[0010] The present application relates to the technical field of beverage preparation equipment, and in particular to a weighing module, beverage preparation equipment and a control method thereof. Background Art

[0011] There are many factors to consider when brewing a high-quality cup of coffee, and one of the most influential factors is the coffee powder. The ratio of coffee powder to water directly affects the extraction effect of the coffee, which we usually call the extraction rate. In order to make a better coffee, baristas have high extraction rates.

[0012] Currently, coffee machines on the market, such as the widely used fully automatic coffee machines, generally use a timer to control the amount of ground coffee. This means controlling the weight of the ground coffee by controlling the operating time of the grinding assembly. As we all know, there are single-origin coffees and blends, but both types of coffee beans have significant differences. The size and roasting levels of the beans vary, leading to varying hardness. This leads to errors in controlling the weight of the ground coffee by controlling the operating time of the grinding assembly, resulting in inconsistent quality of the extracted coffee.

[0013] For commercial use, existing fully automatic coffee machines are unable to accurately calculate the weight of coffee grounds required for each cup of coffee. This results in large fluctuations in the weight of coffee grounds, leading to wasted coffee beans and increased business costs. Therefore, businesses urgently need a fully automatic coffee machine that can accurately determine the amount of coffee grounds required for each cup of coffee. This ensures consistent quality for each cup of coffee, keeps the weight of coffee grounds within a fixed error range, and avoids waste and saves costs.

[0014] To address the aforementioned technical issues, existing beverage preparation equipment incorporates a weighing module that accurately measures the weight of ground coffee, ensuring a uniform amount of ground coffee and consistent quality. However, existing weighing modules are difficult to disassemble and assemble, and can easily interfere with surrounding mechanisms. Technical issues

[0015] The main purpose of this application is to propose a weighing module, a beverage preparation device and a control method thereof, aiming to solve the problem of inconvenience in disassembling and assembling the weighing module within the machine body. Technical Solutions

[0016] To achieve the above-mentioned objectives, the present application proposes a weighing module, which is used to be housed in the inner cavity of a body of a beverage preparation device and is located at the outlet end of the grinding module and / or the inlet end of the brewing module in the body;

[0017] Wherein, the weighing module is provided with a plug-in structure, and the plug-in structure is detachably connected to a matching structure provided on the body. Beneficial effects

[0018] In the technical solution provided in the application, the weighing module is arranged between the grinding module and / or the brewing module, and is independent of the grinding module and the brewing module structure, so that the disassembly and assembly of the weighing module will not affect the grinding module and the brewing module too much; the movable coordination between the plug-in structure and the matching structure enables the machine body to be directly removed from the inner cavity to the outside after the inner cavity is opened, and also to be movably loaded from the outside to the inner cavity, with the characteristics of convenient disassembly and assembly and easy operation; the grinding module grinds the powder, and the powder is discharged outward at the outlet end of the grinding module and before entering the inlet end of the brewing module. It will be received in the weighing module and accurately weighed by the weighing module, thereby ensuring that the amount of powder of the extracted coffee is uniform and the quality is stable.

[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0065] First application example:

[0066] Referring to Figures 1 to 17 , the present application provides a beverage preparation device comprising a housing and a weighing module 10. The housing comprises at least a housing defining an inner cavity, and a grinding module and / or brewing module disposed within the inner cavity, with the housing having a mating structure. Furthermore, to enable intelligent and automatic operation of the beverage preparation device, the housing may further include a control device housed within the inner cavity of the housing and / or a display module at least partially exposed on the outer wall of the housing.

[0067] This design does not limit the specific type of beverage preparation device; it can be any device or product that can extract and brew materials to ultimately produce a beverage. Specifically, the beverage preparation device can be, but is not limited to, a coffee machine, a soymilk maker, a bean grinder, a food processor, etc. Correspondingly, the materials involved in this application can be beans such as coffee beans and soybeans. For ease of understanding, the following embodiments are described using a coffee machine as an example of a beverage preparation device, where the materials include coffee beans that have not been ground by a grinding module, as well as coffee powder obtained after being ground by a grinding module.

[0068] The grinding module may include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder defines a grinding chamber; the grinding mechanism includes, for example, a movable cutting tool and a first drive assembly that actuates the cutting tool. The cutting tool can be designed with a desired shape and suitable motion to facilitate puncturing, grinding, stirring, and other crushing operations on granular materials such as coffee beans. Examples of these tools include bayonets and blade discs. The outlet of the grinding module refers to the outlet of the grinding cylinder.

[0069] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee beverage. The brewing mechanism is mainly configured as a pressing mechanism, a heating mechanism and / or a water supply component according to different brewing requirements. In addition, the brewing mechanism can also be configured as, but is not limited to, a refrigeration mechanism and / or a milk supply component, etc. according to actual needs, to obtain different types of coffee beverages. The inlet end of the brewing module refers to the inlet end of the brewing cylinder.

[0070] In view of the above, the beverage preparation equipment includes a grinding module and a brewing module, and the weighing module 10 is arranged at the outlet end of the grinding module and the inlet end of the brewing module as an example for explanation. It should be emphasized that when the weighing module 10 is used in the beverage preparation equipment, the weighing module 10 can be assembled into the body in any suitable posture according to actual needs. For ease of understanding, in the following embodiments, the beverage preparation equipment as a whole and its components all have approximately vertical horizontal and vertical directions. Among them, the horizontal direction is any suitable direction on the horizontal plane, which can specifically be a first horizontal direction and a second horizontal direction arranged in a cross pattern. The angle between the first horizontal direction and the second horizontal direction can be set to approximately 90°.

[0071] Please refer to Figures 1 to 2. The present application also provides a weighing module 10. The weighing module 10 is used in the above-mentioned beverage preparation equipment and is specifically accommodated in the inner cavity of the casing. The weighing module 10 can be set between the outlet end of the grinding module and the inlet end of the brewing module in the body. The inlet end of the weighing module 10 can be connected to the outlet end of the grinding module in an on-off manner, and the outlet end of the weighing module 10 can be connected to the inlet end of the brewing module in an on-off manner. Among them, when the inlet end of the weighing module 10 is connected to the outlet end of the grinding module, and the outlet end of the weighing module 10 is disconnected from the inlet end of the brewing module, the weighing module 10 can receive and accommodate the coffee powder discharged outward from the outlet end of the grinding module, and perform the weighing function at the same time or with a delay to run the weighing mode. When the inlet end of the weighing module 10 is connected to the outlet end of the grinding module, and the outlet end of the weighing module 10 is connected to the inlet end of the brewing module, the weighing module 10 mainly plays the function of transitioning powder, does not perform the weighing function, and runs in non-weighing mode.

[0072] Among them, the outer wall of the weighing module 10 is provided with a plug-in structure, which is detachably connected to the matching structure set in the body, and the two are movably connected, so that the weighing module 10 can be removed from the inner cavity of the body under the drive of external force, and can also be installed from the outside of the inner cavity of the body.

[0073] In the technical solution provided in the present application, the weighing module 10 is arranged between the grinding module and the brewing module, and is independent of the grinding module and the brewing module structures respectively, so that the disassembly and assembly of the weighing module 10 will not affect the grinding module and the brewing module too much; the movable coordination between the plug-in structure and the matching structure enables it to be directly pulled out from the inner cavity of the body after the inner cavity of the body is opened, or to be movably inserted from the outside of the body into the inner cavity, with the characteristics of convenient disassembly and assembly and easy operation; the grinding module grinds the powder, and the powder is discharged outward at the outlet end of the grinding module and before entering the inlet end of the brewing module. It will be received in the weighing module 10 and accurately weighed by the weighing module 10, thereby ensuring that the amount of powder extracted from the coffee is uniform and the quality is stable.

[0074] When the weighing module 10 is used in a beverage preparation device, it is placed in the body of the machine as a modular component. The plug-in structure of the weighing module 10 and the matching structure of the body can be quickly disassembled and assembled. When the weighing module 10 is installed in the housing and located between the grinding module and the brewing module, the current position of the weighing module 10 constitutes the preset installation position:

[0075] In one embodiment, when the weighing module 10 is removed from the machine body, the pre-set installation position becomes vacant, creating a gap between the grinding module and the brewing module. Optionally, a plug-in structure can also be provided on the grinding module and / or the brewing module. Based on this plug-in structure, the grinding module and / or the brewing module can be plugged into a mating structure on the machine body to replace the pre-set installation position, thereby placing the brewing module and the grinding module as close together as possible to prevent powder from scattering during transfer.

[0076] Alternatively, in one embodiment, a detachable or integral, deformable connecting structure can be provided between the grinding module and / or the brewing module. When the weighing module 10 is installed in the housing, the connecting structure compresses and deforms; conversely, when the weighing module 10 is removed from the housing, the connecting structure extends and deforms, thereby connecting the outlet of the grinding module and the inlet of the brewing module, thereby preventing a gap from forming between the grinding module and the brewing module. The connecting structure can be a soft rubber channel, etc., and the specific form is not limited.

[0077] Based on this, further, in one embodiment, the beverage preparation device can also identify whether the weighing module 10 is installed in the casing through its own preset or externally connected control device, combined with one or several sensor devices, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0078] In view of the above, it can be seen that the beverage preparation device and / or the weighing module 10 are pre-set with optional weighing mode and non-weighing mode. In actual application, the beverage preparation device can adjust whether the whole machine is currently in weighing mode or non-weighing mode by manual setting based on, for example, preset buttons. Among them, when the whole machine is in non-weighing mode, the weighing component can be in an uninstalled state when it is removed from the inside of the casing, or it can be in an installed state installed in the casing. When the weighing module 10 is in an installed state installed in the casing, the weighing module 10 can be used as a transfer mechanism for conveying powder from the grinding module to the brewing module as described above. The weighing module 10 is set to a normally open form, which is equivalent to a connecting pipeline. When the powder is conveyed from the grinding module to the brewing module, the powder passes through the weighing module 10 freely and unimpeded.

[0079] Specifically, the plug-in structure and the matching structure complement each other in terms of setting quantity, setting orientation, structural type, etc., and with the coordination of the two, the weighing module 10 can move into the inner cavity of the casing along a specified direction under the drive of an external force, and move out from the inner cavity of the casing along a specified direction.

[0080] There are many solutions for plug-in and matching structures to achieve this purpose:

[0081] In one embodiment, one of the plug-in structure and the mating structure may provide a rolling surface, while the other may be configured as a roller. The rolling surface may be a flat surface that allows the roller to roll in any desired direction. The rolling surface may also be a concave surface with a certain curvature to restrict the rolling direction of the roller. Accordingly, the roller may be a one-way roller or a universal roller.

[0082] In one embodiment, referring to Figures 1 and 2 , one of the plugging and unplugging structure and the mating structure is a first chute, and the other is a first protrusion 271. The first protrusion 271 is slidably connected and mated with the first chute. Taking the first chute as an example, the first chute is arranged along the desired plugging and unplugging direction. A single first chute can be provided on the weighing module 10 or the machine body. Alternatively, at least two first chute can be spaced apart along another direction substantially perpendicular to the plugging and unplugging direction. The first protrusion 271 is adaptively configured to accommodate the first chute.

[0083] For example, as shown in Figures 1 and 2, first protrusions 271 are provided on the weighing module 10, and are located on opposite sides in a direction substantially perpendicular to the insertion and removal direction. A first chute is provided on the housing (not shown in the figures). It should be noted that the first chute can be provided at any suitable location within the housing, such as on the inner wall of the housing, on the outer wall of the grinding module adjacent to the weighing module 10, or on the outer wall of the brewing module adjacent to the weighing module 10.

[0084] The coordinated arrangement of the first sliding groove and the first sliding protrusion 271, on the one hand, can realize the plugging and unplugging operation of the weighing module 10 relative to the inner cavity of the casing more smoothly, and has the characteristics of easy operation, labor-saving and simple structure; on the other hand, the first sliding groove can produce a certain limiting effect on the first sliding protrusion 271, so as to accurately guide the plugging and unplugging operation of the weighing module 10 relative to the inner cavity of the casing, thereby avoiding position displacement of the weighing module 10 during the plugging and unplugging process, resulting in poor plugging and unplugging effect.

[0085] According to actual needs, in a further solution, an interference structure can be set at the movable connection between the plug-in structure and the mating structure. For example, an interference structure is set downstream of the plug-in structure and the mating structure in the insertion direction, so that the weighing module 10 is subjected to gradually increasing interference resistance during the process of being inserted into the inner cavity of the casing, so that when the weighing module 10 is finally inserted into the inner cavity of the casing, the interference resistance between the two is sufficient to prevent the weighing module 10 from escaping from the inner cavity of the casing (without sufficient external force to drive it), thereby achieving self-locking in the current installation state.

[0086] Specifically, the interference structure is, for example, provided with an interference protrusion at a corresponding position of the first chute, or the groove width at a corresponding groove section of the first chute is set to be gradually narrowed, etc. The specific setting is not limited.

[0087] Alternatively, in one embodiment, the weighing module 10 further includes a first connector, which connects and fixes the weighing module 10 and the body when the weighing module 10 is accommodated in the casing. The first connector can firmly lock the weighing module 10 in the inner cavity of the casing. There are many specific ways of the first connector, but it is not limited to one or more of the following: a screw connection between a screw connection part and a connecting hole, a magnetic fixation between a magnetic part and a magnetic matching part, a buckling fixation between a snap fastener and a buckle hole, a vacuum adsorption fixation between an adsorption part and an adsorption matching part, and an adhesive fixation between two adhesive parts.

[0088] As shown in Figures 1 and 2, the first connecting member can be specifically configured as a screw, bolt or other threaded member (not shown in the drawings), and a first connecting hole 272 is correspondingly provided on the weighing module 10, and the threaded member is threadedly connected to the first connecting hole 272.

[0089] Next, in one embodiment, the first connector and the plug-in structure are arranged on different side surfaces of the weighing module 10. For example, when the plug-in structure is arranged at intervals along another direction substantially perpendicular to the plug-in direction, the first connection hole 272 / first connector can be arranged on any side of the weighing module 10 in the plug-in direction. In this way, the structural arrangement and connection operation of the first connector / first connection hole 272 can be made without interfering with the movable connection and cooperation between the plug-in structure and the matching structure. In addition, the first connector / first connection hole 272 and the plug-in structure / matching structure can limit the weighing module 10 in more directions, ultimately helping to stabilize the connection of the weighing module 10 within the inner cavity of the housing.

[0090] The plug-in structure can be provided at any location on the weighing module 10. Specifically, the weighing module 10 can include at least one module unit and a first shock-absorbing structure 300. When the weighing module 10 includes a single module unit, the first shock-absorbing structure 300 can be provided between the module unit and the machine body. When the weighing module 10 includes at least two modules, the first shock-absorbing structure 300 can be provided between at least one module unit and the machine body, and / or between two adjacent modules.

[0091] It should be noted that when the weighing module 10 includes a single module, the module can be directly configured as a weighing device as described below (see below for the specific structure). When the weighing module includes at least two modules, the division method of the two modules is not limited. In this case, at least one of the modules can be provided with a plug-in structure.

[0092] Specifically, in the embodiment shown in Figures 1 and 2, the two modules can be specifically a weighing body 100 and a base 270, with the base 270 having a plug-in structure. The weighing body 100 refers to the portion of the weighing module 10 that primarily performs the weighing function; the base 270 refers to the portion of the weighing module 10 that primarily provides support, assists with installation, and provides structural reinforcement.

[0093] Specifically, the base 270 can be one or more of a block-shaped structure, a plate-shaped structure, a frame-shaped structure, and the like. For example, as shown in FIG2 , the base 270 is generally plate-shaped, and the plate segments on opposite sides of the base 270 are bent in the same direction and then bent and extended in opposite directions away from each other or in relatively close directions, forming two flanges. The flanges directly constitute the first sliding protrusion 271. The plate segment on the other side of the base 270 is bent in the same direction to form another flange, which is provided with a first connecting hole 272. This facilitates the formation of the flange as a whole and helps to appropriately raise the weighing body 100.

[0094] The first shock-absorbing structure 300 can be directly a spring member, a metal shrapnel or other structure, or a structure such as an elastic block made of elastic material. The first shock-absorbing structure 300 can be set as one, in which case the first shock-absorbing structure 300 is set as close as possible to the center of gravity of the weighing body 100. Alternatively, the first shock-absorbing structure 300 can be set as multiple, and multiple first shock-absorbing structures 300 can be set at the center of gravity of the weighing body 100, and can also be evenly set around the periphery of the center of gravity of the weighing body 100. The setting of the first shock-absorbing structure 300 can dampen the action between the weighing body 100 and the base 270, thereby helping the weighing body 100 to better and more accurately realize its weighing function.

[0095] Specifically, the base 270 can be configured to be fixed relative to the aforementioned body. Taking the example of the base 270 being fixed relative to the housing, the base 270 and the housing can be integrally formed, or the base 270 and the housing can be separately formed and then connected and fixed. Of course, in other embodiments, the weighing body 100 can also be configured to be fixed relative to the aforementioned body.

[0096] When the two modular units are the aforementioned base 270 and the weighing body 100, the weighing body 100 includes a weighing device 130 for weighing. In this case, the plug-in structure can be specifically disposed on the base 270. This allows the plug-in structure and the weighing body 100 to be relatively separate and structurally independent, thereby helping to reduce mutual interference between the two.

[0097] Furthermore, the aforementioned mating structure and the housing at its location can also be integrally formed, or they can be separately formed and then removably or non-detachably connected. When the mating structure and the housing at its location are separately formed and then removably or non-detachably connected, a second shock-absorbing structure can be further provided between them. The configuration of the second shock-absorbing structure is similar to that of the first shock-absorbing structure described above and will not be further described.

[0098] Based on any of the above embodiments, the structural design of the weighing body 100 is as follows:

[0099] First, referring to Figures 2 to 9, in one embodiment, the weighing module 10 includes a receiving container 110, a driving device 120, and a weighing device 130. The receiving container 110 includes a container body 111 and an opening and closing member. The container body 111 is provided with a material delivery channel 111a for connecting the outlet end of the grinding module and the inlet end of the brewing module. The opening and closing member is movably disposed relative to the container body 111, having an open position that connects the material delivery channel 111a and a closed position that closes the material delivery channel 111a. The driving device 120 is drivingly connected to the opening and closing member. The weighing device 130 extends along a first horizontal direction and includes a weighing portion 131 and a fixing portion 132 located at opposite ends of the first horizontal direction. The weighing portion 131 is fixedly connected to the receiving container 110, and the fixing portion 132 is fixedly connected to the driving device 120. The weighing portion 131 is configured not to bear the weight of the driving device 120.

[0100] The container body 111 is generally cylindrical, with the space within the cylinder directly defining a feed channel 111a. The feed channel 111a can extend in a direction as needed, for example, along the direction of gravity or in a direction inclined relative to gravity. Of course, the feed channel 111a can be configured as a straight channel structure or, depending on actual needs, as a channel structure that is at least partially curved.

[0101] The opening and closing member can be positioned anywhere within the feed channel 111a, for example, at the inlet end, at the outlet end, or anywhere between the inlet and outlet ends of the feed channel 111a. For example, as shown in Figures 3 and 4 , the opening and closing member is positioned at the outlet end of the feed channel 111a and externally positioned within the container body 111. The opening and closing member is generally plate-shaped. The shape and dimensions of the portion of the opening and closing member that covers the outlet end of the feed channel 111a can be adapted to that of the outlet end.

[0102] There is no restriction on the movement of the opening and closing member relative to the container body 111:

[0103] In one embodiment, the opening and closing member can be flipped relative to the container body 111. Specifically, one end of the opening and closing member is rotatably connected to an edge of the outlet end of the material delivery channel 111a, and the other end of the opening and closing member can flip to a closed position toward the other edge of the outlet end of the material delivery channel 111a, and flip to an open position toward the other edge of the outlet end of the material delivery channel 111a.

[0104] Alternatively, in the embodiment shown in Figures 3 and 4, the opening and closing member can be translated relative to the container body 111. Specifically, the opening and closing member is offset to one side of the outlet end of the material delivery channel 111a and can be translated to a closed position toward the other side of the outlet end of the material delivery channel 111a, and can be translated to an open position away from the other side of the outlet end of the material delivery channel 111a.

[0105] The configuration of the drive mechanism 120 is related to the movement of the opening and closing member. The drive mechanism 120 includes at least a drive assembly, which is operatively connected to the opening and closing member to drive the opening and closing member to move back and forth between a closed position and an open position. The fixing portion 132 can be connected to a portion of the drive assembly that is not connected to the opening and closing member and is relatively fixed, such as the housing structure.

[0106] Alternatively, please refer to Figures 5 to 7 for details. In one embodiment, the driving device 120 includes a docking seat 121 and a driving assembly. The docking seat 121 is connected and fixed to the fixing portion 132. Specifically, in one application, the fixing portion 132 is arranged at one end of the top of the docking seat 121; the driving assembly is arranged on the docking seat 121 and is detachably connected to the opening and closing member, wherein when the driving assembly is connected and drives the opening and closing member to move to the open position, it can continue to maintain connection with the opening and closing member; after the driving assembly is connected and drives the opening and closing member to move to the closed position, the driving assembly is disconnected from the opening and closing member and separated from each other, and is in a non-contact state. A receiving cavity can be formed inside the docking seat 121. The docking seat 121 can be set to be closed, and the driving assembly is at least partially sealed and accommodated in the receiving cavity. The setting of the docking seat 121 can provide a connection space for the fixing portion 132 that is independent of the driving assembly, and also provide a stable and sealed receiving space for the driving assembly.

[0107] It should be emphasized that in one application, the weighing device 130 is roughly cantilevered. This design, by locating the drive assembly at the docking station 121 and connecting the fixing portion 132 to the docking station 121, allows the drive assembly to directly apply downward force to the fixing portion 132, bearing only the container body 111 and the powder contained therein. Compared to conventional solutions in which the drive assembly and container body 111 are integrally arranged in the weighing unit 131, the weighing unit 131 in this design bears virtually no weight of the drive assembly. This effectively prevents the heavier drive assembly from placing a load on the weighing unit 131, thereby ensuring that the weighing results of the weighing unit 131 in this design are more sensitive and accurate. Furthermore, vibrations generated by the drive assembly during operation are effectively prevented from causing measurement deviations in the weighing unit 131, thereby ensuring that the weighing process of the weighing unit 131 in this design is more stable and efficient.

[0108] In addition, it can be understood that since the weighing device 130 is roughly in the shape of a cantilever extending along the first horizontal direction, its weighing part 131 and the fixing part 132 are respectively arranged at both ends of the first horizontal direction. Therefore, in actual application, please refer to Figures 1 and 17. The weighing part 131 is connected to the receiving container 110, and at least the part of the receiving container 110 connected to the weighing part 131 can be suspended vertically below the weighing part 131, or it can be supported vertically above the weighing part 131. Similarly, the fixing part 132 is connected to the driving device 120, and the part of the driving device 120 that can be connected to the fixing part 132 can be connected vertically below the fixing part 132, or it can be connected vertically above the fixing part 133. However, for ease of understanding, in the following embodiments, the example is taken as follows: at least the portion of the receiving container 110 connected to the weighing part 131 is suspended vertically below the weighing part 131, and at least the portion of the driving device 120 connected to the fixing part 132 is connected vertically below the fixing part 132.

[0109] In one embodiment, the receiving container 110 also includes a connecting seat 113, the weighing part 131, the connecting seat 113 and the container body 111 are directly or indirectly fixedly connected to each other, and the opening and closing member can be installed on the connecting seat 113 so as to be movably translated in a first horizontal direction close to and away from the container body 111.

[0110] Specifically, the connecting seat 113 extends and is located below the weighing device 130 and is connected to the below of the weighing device 130, the container body 111 and the weighing part 131 are connected and fixed to the connecting seat 113, and the opening and closing member can be installed on the connecting seat 113 for translation and movement in the first horizontal direction close to and away from the container body 111, and the projection of the weighing device 130 on the horizontal plane is completely located within the projection plane of the connecting seat 113 on the horizontal plane; the driving assembly includes a driver 122 and a rotating member 123, the driver 122 and the fixed part 132 are both connected and fixed to the docking seat 121, the driver 122 is drivingly connected to the rotating member 123, one of the connection points between the rotating member 123 and the opening and closing member is provided with a guide groove 114b extending along the second horizontal direction, and the other is provided with a guide protrusion 123a, and during the rotation of the rotating member 123, the guide protrusion 123a has a first stroke section in which it contacts the guide groove 114b and slides along the guide groove 114b, and a second stroke section that disengages from the guide groove 114b.

[0111] In another embodiment, the container body 111 may be connected and fixed to the weighing part 131 , and the connecting seat 113 and the weighing device 130 , as well as the connecting seat 113 and the container body 111 , may be separately connected in cooperation.

[0112] The driver 122 performs a rotational output and can specifically be a motor having a rotatably arranged output shaft. The rotating member 123 is connected to the output shaft of the driver 122 so that, under the rotational drive of the output shaft of the driver 122, the rotating member 123 can be driven by the driver 122 to rotate in the same direction, ultimately driving the guide protrusion 123a to slide against and contact the guide groove 114b. Because the guide groove 114b extends along the second horizontal direction, the rotational motion of the rotating member 123 can be converted into a translational motion that pushes the guide groove 114b along the first horizontal direction and the movement of the protrusion 123a of the rotating member 123 within the guide groove 114b toward the second horizontal direction, ultimately achieving the purpose of driving the opening and closing member to perform translational movement along the first horizontal direction. The second horizontal direction in which the guide groove 114b extends is perpendicular to the first horizontal direction of the translational motion of the guide groove 114b. In the above description, when the guide protrusion 123a is in the first stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a mutually contacting and connected state, and the driving force of the driver 122 can ultimately be transmitted to the opening and closing member, thereby switching the opening and closing member between the open position and the closed position. When the guide protrusion 123a is in the second stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a disconnected state, and the driving force of the driver 122 cannot be transmitted to the opening and closing member, and the opening and closing member is locked in the current position (specifically, the closed position). At this time, the driving device 120 and the receiving container 110 remain substantially separated. The driving device 120 independently applies force to the fixing portion 132 of the weighing device 130, and the receiving container 110 independently applies force to the weighing portion 131 of the weighing device 130. This helps to prevent the gravity of the driving device 120 from affecting the measured weight of the material received by the receiving container 110, thereby further helping to improve the weighing accuracy and optimize the weighing effect.

[0113] It should be noted that when the guide protrusion 123a is in the first travel segment, the guide protrusion 123a is in sliding engagement with at least the sidewall of the guide groove 114b. Optionally, the top of the guide protrusion 123a can be in sliding engagement with the bottom wall of the guide groove 114b, thereby ensuring a smoother sliding connection between the guide protrusion 123a and the guide groove 114b. Alternatively, the top of the guide protrusion 123a can be spaced apart from the bottom wall of the guide groove 114b, thereby ensuring that the connecting base 113 remains suspended above the guide protrusion 123a and the docking base 121. In this manner, apart from the weighing portion 131 in direct contact with the container body 111 and the fixing portion 132 in direct contact with the docking base 121, no other components come into contact with the weighing device 130. This minimizes any other contact during weighing by the weighing device 130, thereby ensuring accurate weighing.

[0114] In a preferred embodiment, the guide protrusion 123a may include a boss and a ring sleeved on the outer circumference of the boss, wherein the ring can be sleeved on the boss and rotate around the boss, and the ring contacts and drives the opening and closing part to move in the guide groove 114b. The friction force formed by the contact of the ring driving the guide groove 114b is converted into rolling friction force, thereby reducing the friction generated and preventing wear and friction noise caused by long-term contact friction.

[0115] Further, please refer to Figures 5 to 7. In one embodiment, the outer top wall of the docking seat 121 is provided with a circular limiting hole 121f that passes through the inner wall and an arc-shaped groove 121a that is provided on the outer periphery of the limiting hole 121f. The arc length of the arc-shaped groove 121a is not less than the arc length corresponding to the guide protrusion 123a when performing the first stroke segment. The rotating member 123 includes a rotating arm 123c and a rib 123c that protrudes downward from the bottom end of the rotating arm 123c to extend into the arc-shaped groove 121a. 3d, a rotating boss 123e protrudes from one radial end of the rotating arm 123c, facing toward the docking seat 121. The rotating boss 123e is rotatably connected to the limiting hole 121f of the docking seat 121. A guide protrusion 123a protrudes from the other radial end of the rotating arm 123c, facing away from the docking seat 121. A rib 123d slides along the side walls of the arcuate groove 121a. The driver 122 is housed within the docking seat 121, and the drive shaft extends upward and outward from the through-limiting hole 121f. To enhance the structural strength of the rotating arm 123c, in one embodiment, the rotating member 123 may further include fan-shaped plates 123b extending from both sides of the rotating arm 123c.

[0116] In one embodiment of the present application, the rotating boss 123e is mounted on the drive shaft of the driver 122 and is located above the limiting hole 121f. The outer diameter of the rotating boss 123e is larger than the aperture of the limiting hole 121f, so that the rotating boss 123e can cover the area above the limiting hole 121f. In another embodiment, the rotating boss 123e extends into the limiting hole 121f, wherein the outer diameter of the rotating boss 123e substantially matches the aperture of the limiting hole 121f, so that the rotating boss 123e fills the entire limiting hole 121f.

[0117] Specifically, the arcuate groove 121a can be arranged along the entire circumference of the rotation axis of the rotating member 123, so that the rib 123d can slide along the entire circumference of the side groove wall of the arcuate groove 121a, thereby achieving unidirectional and full-circumferential rotation of the rotating member 123. Alternatively, the arcuate groove 121a can be arranged partially along the circumference of the rotation axis of the rotating member 123, so that when the rib 123d slides along the side groove wall of the arcuate groove 121a, the rotating member 123 can achieve unidirectional rotation of a limited arc length.

[0118] The rotating arm 123c, rib 123d, and guide protrusion 123a of the rotating member 123 can be integrally formed, or they can be formed separately and then removably or non-removably connected and fixed. The provision of the rotating arm 123c and rib 123d helps to reduce material consumption of the rotating member 123 and prevents excessive sliding connection between the rotating member 123 and the guide groove 114b and the arcuate groove 121a, which would increase sliding losses.

[0119] It should be noted that, in order to allow the guide protrusion 123a to extend into and out of the guide groove 114b, in one embodiment, the outer peripheral surface of the guide protrusion 123a and / or the corresponding side groove wall of the guide groove 114b can be configured as an inclined straight surface or an arcuate surface to provide smooth guidance. Alternatively, in one embodiment, the rotating member 123 can be telescopically mounted on the docking seat 121 relative to its own rotational axis, and the arcuate groove 121a can be configured with a gradually increasing depth in the portion corresponding to the second stroke segment.

[0120] As can be seen from the above, the rotation of the rotating member 123 simultaneously drives the guide protrusion 123a to slide along the guide groove 114b, and simultaneously drives the rib 123d to slide along the arcuate groove 121a. Therefore, in order to limit the rotation angle range of the rotating member 123, the sliding strokes of the rotating member 123 itself, the guide protrusion 123a and the guide groove 114b, and the sliding strokes of the rib 123d and the arcuate groove 121a can be specifically configured.

[0121] In view of the above, referring to FIG10 , when the opening and closing member translates along the first horizontal direction, the guide slot 114b extends substantially along a second horizontal direction perpendicular to the first horizontal direction. In this case, the guide slot 114b includes at least a first side slot wall and a second side slot wall disposed opposite each other in the first horizontal direction, both of which extend along the second horizontal direction. If the distance between the first side slot wall and the second side slot wall, i.e., the slot width of the guide slot 114b, is k, and the length of the guide protrusion 123a of the rotating member 123 along the first horizontal direction, i.e., the radius of the guide protrusion 123a when the guide protrusion 123a is cylindrical, is r, then k is greater than twice r. This means that when the guide protrusion 123a is located between the first side slot wall and the second side slot wall, it can only abut against the first side slot wall or the second side slot wall. When the guide protrusion 123a abuts against the first side slot wall or the second side slot wall, the gap between the guide protrusion 123a and the other side slot wall is t. This helps to avoid excessive friction interference between the guide protrusion 123a and the guide groove 114b, ensuring that the guide protrusion 123a can slide along the guide groove 114b.

[0122] If the rotation radius of the guide protrusion 123a, that is, the distance from the rotation center of the rotating member 123 to the guide protrusion 123a is L, and the moving path length of the rotating member 123 driving the opening and closing member is S, then S=2L-k.

[0123] 11 to 14 , if it is defined that when the guide protrusion 123a slides in the guide groove 114b to the first limit position, the opening and closing member is in the open position; when the guide protrusion 123a slides in the guide groove 114b to the second limit position, the opening and closing member is in the closed position.

[0124] In one embodiment, the driver 122 is configured to stop operating immediately when the guide protrusion 123a is driven to move to the first limit position or the second limit position.

[0125] Alternatively, in one embodiment, the driver 122 is configured to continue operating when the guide protrusion 123a is moved to the first limit position or the second limit position, and the driver 122 stops operating after the guide protrusion 123a continues to slide to a certain stroke.

[0126] It should be noted that there are multiple ways to stop the control driver 122:

[0127] In one embodiment, the target rotation angle can be determined by calculating the rotation angle range of the driver 122. For example, based on the structural design parameters of the guide groove 114b, the guide protrusion 123a, etc., the required rotation angle for the guide protrusion 123a to move to the first limit position or the second limit position is calculated, and then the target rotation angle is used as the target rotation angle to control the driver 122 to stop operation.

[0128] Alternatively, in one embodiment, the rotation angle range of the rotating member 123 may be determined by limiting the rotation angle range of the rotating member 123. Specifically, the rotation angle range of the rotating member 123 may be set to be greater than 180° and less than 360°. When the rotation angle range is exceeded, the driver 122 is controlled to stop operating.

[0129] Alternatively, in one embodiment, an additional stop structure can be provided to mechanically stop the rotation of the rotating member 123 or the output shaft. Specifically, the stop structure can be provided, for example, within the guide groove 114b at a predetermined position corresponding to the sliding path of the guide protrusion 123a, or on the docking station 121 at a predetermined position corresponding to the rotation path of the rotating member 123.

[0130] Alternatively, in one embodiment, a sensor device can be provided to determine the active position of the guide protrusion 123a and / or the rotating member 123. Specifically, in conjunction with Figures 5 and 7, in one embodiment, the docking station 121 is provided with a position sensor 121b protruding from the side of the arc-shaped groove 121a, and the position sensor 121b is provided with a sensing portion 121c. The sensing portion 121c can be provided protrudingly on the side surface of the position sensor 121b facing the arc-shaped groove 121a, and the sensing portion 121c and the position sensor 121b can be integrally formed, or can be separately formed and then connected and fixed in a detachable or non-detachable manner. The sensing portion 121c can specifically be provided with a through groove 121d. The through groove 121d is adapted to be provided at the corresponding outer periphery of the rotating member 123. The through groove 121d can, to a certain extent, limit the rotation of the rotating member 123 along its rotation axis without affecting the rotation of the rotating member 123. The rotating member 123 is provided with a triggering portion corresponding to the sensing portion 121 c. When the triggering portion approaches the sensing portion 121 c, the position sensor 121 b is triggered to generate a sensing signal.

[0131] As shown in Figure 15, two of the aforementioned sensing parts 121c or position sensors 121b can be provided at intervals. Taking two sensing parts 121c as an example, the two sensing parts 121c correspond to the open position and closed position of the opening and closing member, respectively. The two sensing parts 121c are provided at intervals on the rotating periphery of the trigger portion of the rotating member 123. The driver 122 drives the rotating member 123 to rotate, and by switching the driver 122 between forward and reverse rotation, the trigger portion switches back and forth between the two sensing parts 121c.

[0132] It should be noted that when the driver 122 is configured to continue to operate for a certain distance after driving the guide protrusion 123a to the first or second limit position before stopping, in one embodiment, the guide protrusion 123a can be configured to disengage from the guide groove 114b after sliding for the distance, thereby completing the clutch connection between the rotating member 123 and the opening and closing member. There are various ways to disengage, such as gradually reducing the groove depth of the corresponding groove section of the guide groove 114b so that the guide protrusion 123a is gradually pushed out of the guide groove 114b; or the guide groove 114b can be configured to be open at both ends in the second horizontal direction so that the guide protrusion 123a can disengage from the guide groove 114b outwardly from the open ends.

[0133] Furthermore, based on the above, and in conjunction with Figures 3 and 4 , in one embodiment, the connecting base 113 is provided with a mounting slot 113a, within which a guide rod 115 is disposed, extending along a first horizontal direction. The opening and closing member may specifically include a cover plate 112 and a slider 114. The cover plate 112 covers the notch of the mounting slot 113a and is provided with a mounting hole 112a extending therethrough and communicating with the mounting slot 113a. The slider 114 is received within the mounting slot 113a and partially extends outward from the mounting hole 112a. The slider 114 is fixed relative to the cover plate 112. The portion of the slider 114 within the mounting slot 113a is provided with a guide hole 114a for slidably engaging with the guide rod 115. The portion of the slider 114 extending outside the mounting slot 113a is provided with the guide slot 114b or the guide protrusion 123a. The number of guide rods 115 provided may be one or multiple guide rods 115 extending side by side in the same direction. The guide holes 114 a are suitable for adaptively adjusting the number and positions of the guide rods 115 .

[0134] Of course, in one embodiment, the opening and closing member may specifically include a cover plate 112 and a slider 114, and the slider 114 is fixedly connected to one side of the cover plate 112 covering the mounting groove 113a and is not exposed on the outside of the cover plate 112. At this time, the above-mentioned guide groove 114b or the guide protrusion 123a may be provided on the side of the cover plate 112 facing away from the mounting groove 113a.

[0135] In addition, in one embodiment, the weighing device 130 can be suspended in the housing and roughly present a cantilever shape. When the weighing module 10 does not receive any material, the counterweight of the weighing part 131 of the weighing device 130 is set to be equivalent to the counterweight of the fixed part 132, or the counterweight of the weighing part 131 of the weighing device 130 is set to be smaller than the counterweight of the fixed part 132. That is, when the weighing module 10 does not receive any material, the structural design is to set the weighing part 131 and the fixed part 132 of the weighing device 130 to be balanced with each other, or at least the weighing part 131 is smaller, so as to avoid the unbalanced force between the weighing part 131 and the fixed part 132 of the weighing device when not weighing, which may cause the cantilever weighing device to deflect, and easily reduce the weighing accuracy of the weighing device after long-term use.

[0136] To facilitate installation of the weighing device, referring to Figures 8 and 9 , in one embodiment, the weighing module 10 further includes a first bracket 140, a second bracket 150, and a second connector 160. The first bracket 140 is detachably connected to the connecting base 113 and the weighing portion 131; the second bracket 150 is detachably connected to the docking base 121 and the fixing portion 132. One of the second bracket 150 and the docking base 121 is provided with a second slide groove 121e, and the other is provided with a second slide protrusion 151 that slidably engages with the second slide groove 121e. When the second bracket 150 and the docking base 121 are slidably connected, the second connector 160 connects and secures the second bracket 150 to the docking base 121. Both the first bracket 140 and the second bracket 150 can be configured in a plate or sheet shape, making them easier to fold to fit the shapes of the docking base 121 and the connecting base 113, and helping to reduce the weight of the entire device. A limiting groove 141 can be provided on the side of the first bracket 140 facing away from the connecting seat 113, and the weighing part of the weighing device can be limitedly installed in the limiting groove 141 and fixed to the first bracket 140 through a connecting piece. The setting of the second sliding protrusion 151 and the second sliding groove 121e can be specifically referred to the setting of the first sliding protrusion 271 and the second sliding groove 121e, and no further details are given. The setting of the second sliding protrusion 151 and the second sliding groove 121e helps to achieve the plug-in and unplug fixation between the second bracket 150 and the docking seat 121, and the sliding connection direction between the second sliding protrusion 151 and the second sliding groove 121e is different from the weighing direction of the weighing part and the counterweight direction of the fixing part 132, so as to avoid excessive influence on the weighing function of the weighing device. Similarly, the setting of the above-mentioned connecting piece and the second connecting piece 160 can be specifically referred to the above-mentioned first connecting piece, and no further details are given.

[0137] In addition, in view of the above, if the receiving container 110 includes a container body 111 and an opening and closing member as described above, in one embodiment, the driving device includes a main body portion and a power output portion. Specifically, when the driving device includes a driving assembly as described above, the main body portion of the driving device is, for example, the driver 122; when the driving device includes a driving assembly and a docking station 121 as described above, the main body portion of the driving device is, for example, the driver 122 and the docking station 121. When the output shaft of the driver 122 is directly connected to the opening and closing member, the output shaft of the driver 122 directly constitutes the power output portion of the driving device; when the output shaft of the driver 122 is connected to the opening and closing member through the above-mentioned rotating member 123, the output shaft of the driver 122 and the rotating member 123 together constitute the power output portion of the driving device.

[0138] Next, referring to Figure 16, in one embodiment, the outlet end of the container body 111 is spaced apart from the main body of the drive device in the vertical direction, and a connection space is reserved at the space. The connection space allows the power output portion of the drive device to be connected to the opening and closing member in a disengageable manner. In this case, the weighing module 10 may also be provided with a stopper 600 on at least one side of the connection space. The stopper 600 can effectively prevent powder discharged outward through the outlet end of the container body 111 from entering the connection space, thereby preventing the powder from clogging or obstructing the clutch connection between the power output portion of the drive device and the opening and closing member.

[0139] Furthermore, in one embodiment, the stopper 600 may be protruded from at least one of the receiving container 110, the opening and closing member, and the connecting seat 113 toward the driving device, and may be integrally formed with the receiving container 110, the opening and closing member, and the connecting seat 113, or may be separately formed and then detachably or non-detachably connected thereto. And / or in one embodiment, the stopper 600 may be protruded from at least one of the docking seat 121 and the driver 122 toward the weighing body 100, and may be integrally formed with the docking seat 121 and the driver 122, or may be separately formed and then detachably or non-detachably connected thereto.

[0140] In one embodiment, the connection space has a first side proximal to the container body 111 and two second sides disposed on opposite sides of the first side. In this case, the blocking member 600 can be disposed directly on the first side of the connection space and / or on at least one of the second sides. The positioning of the blocking member 600 can be flexibly determined based on actual application requirements.

[0141] In one embodiment, at least one surface of the stopper 600 facing the container body 111 may be smoothed. The smoothing method may include, but is not limited to, substantially reducing the surface roughness of the side surface, providing a smooth material layer on the side surface, and the like. The smooth material may be, for example, glass, ceramic, or some metals.

[0142] Alternatively, in one embodiment, at least one side surface of the baffle 600 facing the container body 111 may be subjected to a repulsive treatment. The repulsive treatment is to guide the approaching powder away from the baffle 600. The repulsive treatment scheme may include, but is not limited to, providing a layer of electrostatic repulsive material on the side surface, providing air holes on the side surface and blowing the air holes outward, etc. Examples of the electrostatic repulsive material include antistatic organic glass plates (antistatic acrylic plates), antistatic PVC plates (antistatic polyvinyl chloride plates), antistatic PC plates (antistatic polycarbonate plates), antistatic PET plates (polyethylene terephthalate), and antistatic nylon plates (MC501CDR6).

[0143] Alternatively, in one embodiment, at least one surface of the baffle 600 facing the container body 111 may be subjected to a suction process. The suction process involves attracting approaching powder to a designated area of ​​the baffle 600. This suction process may include, but is not limited to, providing air holes on the side surface and directing suction inward. The designated area may further include a structure for collecting powder, such as a collection chamber or trough.

[0144] In addition, in view of the above, in one embodiment, the opening and closing member and / or the container body 111 may be provided with a flexible structure at the connection between the two. That is, the flexible structure may be provided on the side of the opening and closing member facing the container body 111, and / or on the side of the container body 111 facing the opening and closing member, and / or independently provided between the opening and closing member and the container body 111. In this way, when the opening and closing member moves to the closed position, the contact between the opening and closing member and the container body 111 is a flexible contact. Compared with the solution in which the two are in rigid contact, this can effectively prevent the opening and closing member and the container body 111 from being completely and tightly contacted due to friction and collision between the opening and closing member and the container body 111, or wear caused by friction of residual powder during long-term use, thereby preventing the opening and closing member and the container body 111 from leaking powder.

[0145] In specific applications, the opening and closing member and / or the container body 111 can be configured as a whole to be made of a flexible material to form a flexible structure as a whole. Alternatively, a flexible material layer can be provided at the connection between the opening and closing member and / or the container body 111, and the flexible material layer forms a flexible structure. The flexible material can further be an elastic material, that is, a material that can elastically deform when subjected to force and restore the elastic deformation when the external force is removed, such as a rubber material, a silicone material, etc. In addition, in view of the above, in one embodiment, a scraper can be provided at the container body 111 and / or the connecting seat 113 toward the opening and closing member. The scraper is provided at a position between the closed position and the open position of the opening and closing member, so that when the opening and closing member returns from the closed position to the open position, the scraper can act on the passing opening and closing member to scrape off the powder brought out by the opening and closing member, thereby preventing the opening and closing member from bringing the powder into the above-mentioned connection space. The powder scraped off by the scraping member will continue to fall to the inlet end of the brewing module, thereby effectively preventing part of the powder from being taken out by the opening and closing member, causing the amount of powder entering the brewing module to be less than the amount of powder weighed by the weighing device 130, resulting in weighing errors.

[0146] There is no limitation on the specific structure of the scraper. For example, the scraper can be set as a plate-like structure, and the plate-like structure is adapted to the shape of the surfaces of the opening and closing parts that are close to each other, so that the scraper can fully adapt to the surface shape of the opening and closing parts and more completely scrape off the powder in the opening and closing parts. Furthermore, the plate-like structure can be made of a rigid material or a flexible material. When the scraper is made of a rigid material, the height T1 of the scraper protruding from the container body 111 and / or the connecting seat 113 can be set to be equal to or slightly less than the distance T2 between the container body 111 and / or the connecting seat 113 and the opening and closing parts. If T1 is equal to T2, the end surface of the scraper is slidably connected to the end surface of the opening and closing parts; if T1 is slightly less than T2, there will not be too much friction interference between the scraper and the opening and closing parts. When the scraping member is made of a flexible material, the height T1 of the scraping member protruding from the container body 111 and / or the connecting seat 113 can be set to be slightly greater than the distance T2 between the container body 111 and / or the connecting seat 113 and the opening and closing member. In this case, the portion of the scraping member that is greater than T2 bends and deforms, which helps increase the sliding contact area between the scraping member and the opening and closing member, thereby more efficiently scraping powder from the end surface of the opening and closing member.

[0147] The scraping member can also be configured as a brush body structure. The brush body structure also includes a plurality of bristles protruding from the container body 111 and / or the connecting seat 113. Similarly to the above, the bristles can be made of a rigid material or a flexible material.

[0148] As shown in FIG4 , the weighing device 130 is further provided with a fastening mechanism for securing the opening and closing member (e.g., the cover 112) against the container body 111 when the opening and closing member is in the closed position. The fastening mechanism can be configured as a latching structure or a magnetic structure 117. Specifically, taking the magnetic structure 117 as an example, at least one of the opening and closing member and the weighing module 10 is provided with the magnetic structure 117, while the other is configured to be at least partially made of a metal containing iron, cobalt, and nickel, or is also provided with another magnetic structure with opposite magnetic polarity. Specifically, at least one of the opening and closing member and the container body 111 can be provided with the magnetic structure 117, while the other can be configured to be at least partially made of a metal containing iron, cobalt, and nickel. Two magnetic structures 117 can be provided, one located on either side of the symmetric axis of the container body 111 along the first horizontal direction of the weighing device 130. Since the connecting base 113 is connected to the container body 111 and the opening and closing member can be movably received in the connecting base 113, the fastening mechanism can also be provided on the connecting base 113. Preferably, the fastening mechanism is arranged around the outer periphery of the outlet of the container body 111. In other embodiments, the fastening mechanism can be arranged on at least one of the machine body, the brewing module, and the grinding module.

[0149] In addition, in view of the above, in one embodiment, when the weighing device 130 realizes the connection between the fixing part 132 and the driving device 120 through the second bracket 150 as described above, if the connection direction between the fixing part 132 and the weighing part 131 is the first horizontal direction, then the second bracket 150 can be specifically extended along the second horizontal direction that is approximately perpendicular to the first horizontal direction, and both opposite ends of the second bracket 150 in the second horizontal direction can be connected to the driving device 120, and the fixing part 132 is roughly connected to the middle part of the second bracket 150 in the second horizontal direction.

[0150] Based on this, the position of the output shaft of the driver 122 and / or the rotation axis of the rotating member 123 can be set to coincide with or be offset from the center of the receiving container 110 and the center of the entire driving device 120 in the vertical direction. When offset, the offset can be in the first horizontal direction and / or the second horizontal direction. By specifically adjusting the structure and rotation angle range of the rotating member 123, the clutch connection with the opening and closing member can be achieved, which helps to reduce the difficulty of the structural design and assembly of the output shaft of the driver 122 and / or the rotating member 123 to a certain extent.

[0151] In addition, in one embodiment, when the beverage preparation equipment as described above is preset with itself or externally connected to a control device, the control device can be electrically connected to the driver 122 so as to flexibly control the operating parameters of the driver 122, thereby correspondingly adjusting the rotational movement of the rotating part 123 and the opening and closing movement of the opening and closing part.

[0152] Based on this, in one embodiment, the control device can control the driver 122 to adjust the closing speed V1 of the opening and closing member during the process of moving from the open position to the closed position to be greater than the opening speed V2 of the opening and closing member during the process of moving from the closed position to the open position. In this way, when the weighing module 10 is required to perform the weighing function, the opening and closing member can move quickly into place.

[0153] Specifically, the closing speed V1 and / or the opening speed V2 can be set to a constant speed, in which case the closing speed V1 is always greater than the opening speed V2. Alternatively, the closing speed V1 and / or the opening speed V2 can be set to a variable speed, in which case the average closing speed V1 is greater than the average opening speed V2.

[0154] And / or in one embodiment, the control device can control the driver 122 to adjust the speed V3 when the rotating member 123 is not connected to the opening and closing member to be greater than the speed V4 when the rotating member 123 is connected to the opening and closing member. In this way, when the driving assembly is required to drive the opening and closing member to open and close, the speed is relatively faster and the time consumed is relatively shorter, which helps to improve the overall efficiency of the opening and closing member's movement, and ultimately improve the working efficiency of the weighing module 10 when performing the weighing function.

[0155] Based on any of the above embodiments, referring to FIG. 21 , the present application further provides a control method for a beverage preparation device, specifically comprising:

[0156] Step E100: Detecting whether the weighing module 10 is installed in the machine body and / or whether the weighing module 10 is activated;

[0157] In this embodiment, the system can detect whether the weighing module 10 is installed in the machine body based on the preset sensor device. The sensor device is, for example, a photoelectric sensor, a force sensor, an image recognition sensor, etc., without limitation. In view of the above, it can be seen that the weighing module 10 is detachably connected to at least one of the housing, the grinding module, and the brewing module. Therefore, for the beverage preparation equipment, there may be a situation where the weighing module 10 has been installed in the machine body and is located at the preset installation position; and there may be a situation where the weighing module 10 is removed from the machine body, at which time the preset installation position may be vacant, or the preset installation position may be occupied by the grinding module and / or the brewing module.

[0158] When it is determined that the weighing module 10 has been installed in the preset installation position, the weighing module 10 may be in an activated state, in which case the structure and functions of the weighing module 10 are normal and can be controlled at any time for purposes such as weighing and pre-acceptance. Alternatively, the weighing module 10 may be in an inactivated state, which may indicate that there is some abnormality in the structure and / or function of the weighing module 10 and timely maintenance is required, or it may indicate that the structure and functions of the weighing module 10 are normal but have not been activated.

[0159] Step E210: When it is determined that the weighing module 10 has been installed in the machine body and / or the weighing module 10 is activated, a system preset or externally input weighing mode program or a non-weighing mode program is selected.

[0160] In this embodiment, when it is determined that the weighing module 10 has been installed in the machine body and / or the weighing module 10 is activated, it indicates that the structure and function of the weighing module 10 are normal and can be used. At this time, the system will provide a weighing mode program or a non-weighing mode program for the user to freely select. Among them, when the weighing mode program is triggered, the weighing module 10 operates in weighing mode, can accept powder and measure the weight of the powder. When the non-weighing mode program is triggered, the weighing module 10 operates in non-weighing mode, and there is no need to measure the weight of the powder.

[0161] Furthermore, after step E100, the method further includes:

[0162] Step E220: When it is determined that the weighing module 10 is not installed in the machine body and / or the weighing module 10 is not enabled, calling a non-weighing mode program preset by the system or input externally.

[0163] In this embodiment, when it is determined that the weighing module 10 is not installed in the machine body and / or the weighing module 10 is not enabled, the weighing function of the weighing module 10 cannot be enabled, so the system can directly or the user can select the non-weighing mode program.

[0164] Specifically, when the weighing module 10 includes a receiving container and an opening and closing member for opening and closing the receiving container as described above, if the weighing module 10 is installed in the machine body and the non-weighing mode program is called, the opening and closing member is in a long-term open state.

[0165] In addition, in one embodiment, when the grinding module and / or the brewing module is provided with a communication structure as described above, the step E100 further includes:

[0166] Step E230: When it is determined that the weighing module 10 is not installed in the machine body, detecting whether the connecting structure is connected to the outlet end of the grinding module and the inlet end of the brewing module.

[0167] In this embodiment, when the weighing module 10 is not installed to the preset installation position, the preset installation position may be vacant, or may be occupied by the grinding module or the brewing module. Among them, when the preset installation position is vacant, the powder discharged by the grinding module cannot directly and completely enter the brewing module, so it is necessary to use a connecting structure. At this time, by detecting the connectivity state of the connecting structure, it can be determined whether the functions of the grinding module and the brewing module can be normally enabled. When the connecting structure connects the outlet end of the grinding module and the inlet end of the brewing module, both the grinding module and the brewing module can operate normally; when the connecting structure is not connected to the outlet end of the grinding module and the inlet end of the brewing module, both the grinding module and the brewing module cannot operate normally, and it is necessary to manually or automatically operate the connecting structure to connect the outlet end of the grinding module and the inlet end of the brewing module, and then start the normal operation of the grinding module and the brewing module.

[0168] In addition, in one embodiment, after the above step E210, the method further includes:

[0169] Step E300: When it is determined that the non-weighing mode program is called, detecting whether the grinding module and / or the brewing module are installed in place.

[0170] In this embodiment, when it is determined that the non-weighing mode program is called, the weighing module 10 does not have the weighing function. At this time, the weighing module 10 may not be installed in the machine body, resulting in the preset installation position being vacant, and it is necessary to determine whether the grinding module and / or the brewing module are installed in place at the preset installation position. Of course, when a connecting structure is provided as described above, it is also possible to determine whether the connecting structure is installed in place at the preset installation position, that is, whether the connecting structure connects the grinding module and the brewing module. Alternatively, the weighing module 10 may have been installed in place in the machine body. At this time, the weighing module 10 only serves a function such as pre-acceptance, and does not affect the normal use of the grinding module and the brewing module. Therefore, it is necessary to determine whether the grinding module and the brewing module are installed in place at their corresponding installation positions.

[0171] It should be emphasized that the beverage preparation equipment in the present application can be a bean grinder for grinding coffee beans. The weighing module 10 can be arranged in the coffee bean grinder, and the grinder is provided with a grinding module. The weighing module 10 is matched with the grinding module of the grinder. The installation and control method of the weighing module 10 in the grinder is consistent with the above. The powder material weighed by the weighing module 10 can be received by the powder bowl and then brewed manually.

[0172] Second application example:

[0173] Referring to Figures 1, 3, 15, and 17, this application provides a beverage preparation device comprising a housing and a weighing module. The housing comprises at least a housing defining an inner cavity, and a grinding module and / or brewing module disposed within the inner cavity, with the housing having a mating structure. Furthermore, to enable intelligent and automatic operation of the beverage preparation device, the housing may further include a control device housed within the inner cavity of the housing and / or a display module at least partially exposed on the outer wall of the housing.

[0174] This design does not limit the specific type of beverage preparation device; it can be any device or product that can extract and brew materials to ultimately produce a beverage. Specifically, the beverage preparation device can be, but is not limited to, a coffee machine, a soymilk maker, a bean grinder, a food processor, etc. Correspondingly, the materials involved in this application can be beans such as coffee beans and soybeans. For ease of understanding, the following embodiments are described using a coffee machine as an example of a beverage preparation device, where the materials include coffee beans that have not been ground by a grinding module, as well as coffee powder obtained after being ground by a grinding module.

[0175] The grinding module may include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder defines a grinding chamber; the grinding mechanism includes, for example, a movable cutting tool and a first drive assembly that actuates the cutting tool. The cutting tool can be designed with a desired shape and suitable motion to facilitate puncturing, grinding, stirring, and other crushing operations on granular materials such as coffee beans. Examples of these tools include bayonets and blade discs. The outlet of the grinding module refers to the outlet of the grinding cylinder.

[0176] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee beverage. The brewing mechanism is mainly configured as a pressing mechanism, a heating mechanism and / or a water supply component according to different brewing requirements. In addition, the brewing mechanism can also be configured as, but is not limited to, a refrigeration mechanism and / or a milk supply component, etc. according to actual needs, to obtain different types of coffee beverages. The inlet end of the brewing module refers to the inlet end of the brewing cylinder.

[0177] In view of the above, the following is specifically described by taking as an example a beverage preparation device in which the body includes a grinding module and a brewing module, and the weighing module is arranged between the outlet end of the grinding module and the inlet end of the brewing module:

[0178] In conjunction with Figures 1 to 3 , the present application further provides a weighing module, which is used in the aforementioned beverage preparation device and is specifically housed within the inner cavity of the housing. The weighing module can be disposed between the outlet of the grinding module and the inlet of the brewing module in the housing. The inlet of the weighing module is connectable and disconnectable to the outlet of the grinding module, and the outlet of the weighing module is connectable and disconnectable to the inlet of the brewing module. When the inlet of the weighing module is connected to the outlet of the grinding module and the outlet of the weighing module is disconnected from the inlet of the brewing module, the weighing module can receive and store coffee powder discharged from the outlet of the grinding module, while simultaneously or with a delay performing a weighing function, thereby operating in a weighing mode. When the inlet of the weighing module is connected to the outlet of the grinding module and the outlet of the weighing module is connected to the inlet of the brewing module, the weighing module primarily serves as a powder transition device and does not perform a weighing function, thereby operating in a non-weighing mode.

[0179] When used in beverage preparation equipment, the weighing module can be assembled into the body in any suitable position, depending on actual needs. For ease of understanding, in the following embodiments, the beverage preparation equipment as a whole and its components are assumed to have approximately perpendicular horizontal and vertical directions. The horizontal direction is any suitable direction on a horizontal plane, specifically a first horizontal direction and a second horizontal direction arranged in an intersecting manner. The angle between the first horizontal direction and the second horizontal direction can be approximately 90°.

[0180] In view of the above, please refer to Figures 1 and 8 for details. In this embodiment, the weighing module includes a weighing device 130, and the weighing device 130 includes a fixing portion 132 and a weighing portion 131 connected in sequence along a first horizontal direction; the fixing portion 132 is used to be connected and fixed to a fixed carrier in the beverage preparation equipment; the weighing portion 131 is suspended relative to the fixed carrier, and the weighing portion 131 is used to bear the gravity of the material to be measured so as to measure the weight of the material to be measured.

[0181] In the technical solution provided by the present application, the fixing portion 132 of the weighing device 130 is connected and fixed to a fixed carrier in the beverage preparation machine; the fixed carrier can be specifically determined based on the installation environment actually reserved for the weighing device 130 by the beverage preparation machine, thereby making the installation of the weighing device 130 in the beverage preparation machine more flexible and adaptable; the weighing portion 131 is suspended relative to the fixed carrier, so that the fixing portion 132 and the weighing portion 131 together form a cantilever structure extending along a first horizontal direction, which helps the weighing portion 131 to effectively bear the gravity of the material to be measured while completing the weight measurement of the material to be measured; and the independent arrangement of the fixing portion 132 and the weighing portion 131 helps to effectively separate the material to be measured from the fixed carrier, preventing related structures on the fixed carrier from interfering with the weighing measurement of the material to be measured by the weighing portion 131. In this way, the weighing module of the present application can not only achieve convenient disassembly and assembly with the beverage preparation machine, but also effectively ensure the efficient execution of its own weighing function.

[0182] It is understandable that the specific forms of the fixed carrier of the beverage preparation equipment can be various: for example, when the weighing module is directly installed on the casing of the machine body, the casing constitutes the fixed carrier. And / or when the weighing module and the grinding module are pre-installed as one body and the two are installed together in the casing, or when the weighing module and the grinding module are separately installed in the casing, but the weighing module is specifically installed on the outer wall of the grinding module, the grinding module constitutes the fixed carrier. And / or when the weighing module and the brewing module are pre-installed as one body and the two are installed together in the casing, or when the weighing module and the brewing module are separately installed in the casing, but the weighing module is specifically installed on the outer wall of the brewing module, the brewing module constitutes the fixed carrier. Of course, when the weighing module is independently arranged in a modular manner, the fixed carrier can also be a carrier structure preset in the weighing module.

[0183] The method of connection and fixing of the fixing portion 132 to the fixing carrier is not limited and can be an integrally formed connection or a separately formed, detachable or non-detachable connection. Specifically, when the fixing portion 132 and the fixing carrier are separately formed and detachably connected, the method of detachable connection between the two is not limited and can be, but is not limited to, one or more of screw connection, snap connection, adhesive connection, and adsorption connection.

[0184] Specifically, the fixing portion 132 can be provided with a plug-in structure directly or indirectly through another component that is relatively fixed to the fixing portion 132; the fixing carrier is correspondingly provided with a mating structure. The plug-in structure and the mating structure are detachably connected, so that the weighing module can be moved outward from the housing under external force and can also be installed outside the housing.

[0185] In one embodiment, one of the plug-in structure and the mating structure may provide a rolling surface, while the other may be configured as a roller. The rolling surface may be a flat surface that allows the roller to roll in any desired direction. The rolling surface may also be a concave surface with a certain curvature to restrict the rolling direction of the roller. Accordingly, the roller may be a one-way roller or a universal roller.

[0186] In one embodiment, one of the plugging and unplugging structure and the mating structure is a first sliding groove, and the other is a first sliding protrusion. The first sliding protrusion is slidably connected and mated with the first sliding groove. Taking the first sliding groove as an example, the first sliding groove is arranged along the desired plugging and unplugging direction. A single first sliding groove can be provided on the fixed portion 132 or on the fixed carrier (directly or indirectly). Alternatively, at least two first sliding grooves can be spaced apart and arranged along another direction substantially perpendicular to the plugging and unplugging direction. The first sliding protrusion is adaptively configured to accommodate the arrangement of the first sliding groove.

[0187] When the weighing module is used in a beverage preparation device, it is placed in the machine body as a modular component. The plug-in structure of the weighing module and the matching structure of the machine body can be quickly disassembled and assembled. When the weighing module is installed in the housing and located between the grinding module and the brewing module, the current position of the weighing module constitutes the preset installation position:

[0188] In one embodiment, when the weighing module is removed from the machine body, the pre-set installation position becomes vacant, creating a gap between the grinding module and the brewing module. Optionally, a plug-in structure can also be provided on the grinding module and / or the brewing module. Based on this plug-in structure, the grinding module and / or the brewing module can be plugged into a mating structure on the machine body to replace the pre-set installation position, thereby placing the brewing module and the grinding module as close together as possible to prevent powder from scattering during transfer.

[0189] Alternatively, in one embodiment, a detachable or integral, deformable connecting structure can be provided between the grinding module and / or the brewing module. When the weighing module is installed in the housing, the connecting structure compresses and deforms; conversely, when the weighing module is removed from the housing, the connecting structure extends and deforms, connecting the outlet of the grinding module with the inlet of the brewing module, thereby preventing a gap from forming between the grinding module and the brewing module. The connecting structure can be a soft rubber channel, etc., and its specific form is not limited.

[0190] Furthermore, in one embodiment, the beverage preparation device can also identify whether the weighing module is installed in the body through its own preset or externally connected control device, combined with, for example, sensor devices, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0191] In view of the above, it can be seen that the beverage preparation device and / or the weighing module are pre-set with optional weighing mode and non-weighing mode. In actual application, the beverage preparation device can adjust whether the whole machine is currently in weighing mode or non-weighing mode by manual setting based on, for example, preset buttons. Among them, when the whole machine is in non-weighing mode, the weighing component can be in an uninstalled state when it is removed from the inside of the casing, or it can be in an installed state installed in the casing. When the weighing module is in an installed state installed in the casing, the weighing module can be used as a transfer mechanism for conveying powder from the grinding module to the brewing module as described above. The weighing module is set to a normally open form, which is equivalent to a connecting pipeline. When the powder is conveyed from the grinding module to the brewing module, the powder passes through the weighing module freely and unobstructed.

[0192] The fixed portion 132 and the weighing portion 131 of the weighing device 130 extend generally along the first horizontal direction. Specifically, the weighing device 130 can be roughly in the shape of a cantilever extending along the first horizontal direction. One section of the cantilever constitutes the fixed portion 132, and the other section constitutes the weighing portion 131. The cantilever section constituting the weighing portion 131 can be directly formed by a force sensing device, or by mounting a force sensing device on the cantilever section. The force sensing device can be, but is not limited to, a stress gauge, a pressure sensor, a tension sensor, a thrust sensor, or the like.

[0193] In actual application, the portion of the weighing device 130 that constitutes the weighing part 131 may have a sufficient receiving surface reserved therein, which is sufficient to receive the powder to be tested discharged from the outlet of the grinding module. Or in one embodiment, the weighing module further includes a receiving container 110, which is used to receive the material to be tested and is directly or indirectly connected and fixed to the weighing part 131. The receiving container 110 mainly serves to receive the powder to be tested. The receiving container 110 is connected and fixed to the weighing part 131, so that the weighing part 131 can measure the weight of the receiving container 110 and the powder to be tested received by the receiving container 110 as a whole. Since the weight of the receiving container 110 is basically unchanged and known, the weight of the powder to be tested received by the receiving container 110 can be easily calculated.

[0194] The receiving container 110 and the weighing unit 131 can be integrally formed, or they can be separately formed and then detachably or non-detachably connected. When the receiving container 110 and the weighing unit 131 are separately formed and then detachably connected, the receiving container 110 and the weighing unit 131 remain relatively independent in structure, facilitating their separate assembly and disassembly.

[0195] Furthermore, in one embodiment, the receiving container 110 includes a container body 111 and a connecting seat 113. The container body 111 is disposed on a side of the weighing portion 131 away from the fixing portion 132; the connecting seat 113 extends from a side wall of the container body 111 toward the weighing portion 131 and is fixedly connected to the weighing portion 131.

[0196] Since the weighing device 130 is roughly in the shape of a cantilever extending along the first horizontal direction, its weighing part 131 and fixing part 132 are respectively arranged at the two ends of the first horizontal direction. Therefore, in actual application, please refer to Figures 1 and 17, the weighing part 131 is connected to the receiving container 110, and at least the part of the receiving container 110 connected to the weighing part 131 can be suspended vertically below the weighing part 131, or it can be supported vertically above the weighing part 131. Similarly, the fixing part 132 is connected to the driving device 120, and the part of the driving device 120 that can be connected to the fixing part 132 can be connected vertically below the fixing part 132, or it can be connected vertically above the fixing part 133.

[0197] When at least the portion of the receiving container 110 connected to the weighing unit 131 is supported vertically above the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing pressure changes. When at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing tension changes.

[0198] The portion where the receiving container 110 is connected to at least the weighing part 131, and the portion where the driving device 120 / fixed carrier is connected to at least the fixing part 132, can be arranged on both sides of the weighing device 130 in the vertical direction, or can be located on the same side of the weighing device 130 in the vertical direction.

[0199] However, for ease of understanding, the following embodiments are described as follows: at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, and at least the portion of the driving device 120 connected to the fixing unit 132 is connected vertically below the fixing unit 132. Specifically, as shown in Figures 8 and 9, the connecting base 113 is suspended below the weighing unit 131 and is fixedly connected to the lower end of the weighing unit 131.

[0200] When a connecting seat 113 is provided, the container body 111 can be directly connected to the weighing part 131, or the container body 111 can be indirectly connected to the weighing part 131 through the connecting seat 113 after being connected to the connecting seat 113. The connecting seat 113 and the container body 111 can be integrally formed, or can be separately formed and then connected in a detachable or non-detachable manner. As shown in Figures 8 and 9, in one embodiment, the weighing module further includes a first bracket 140, which is detachably connected to the weighing part 131 and the connecting seat 113, and the first bracket 140 includes a first main section 140a and two first bending sections 140b. The first main section 140a extends along the second horizontal direction and is connected and fixed to the weighing part 131; the two first bending sections 140b are arranged on opposite sides of the first main section 140a in the second horizontal direction, and are bent and extended along the vertical direction. The two first bending sections 140b are respectively connected and fixed to the two side walls of the connecting seat 113.

[0201] The first bracket 140 can be set to be plate-shaped or sheet-shaped, which is easier to adapt to the shape of the connecting seat 113 and fold, and helps to reduce the weight of the whole machine. The first main section 140a extends along the second horizontal direction, which helps to increase the connection area with the weighing part 131 in the second horizontal direction, and helps to strengthen the connection between the first bracket 140 and the weighing part 131. The two first bending sections 140b can be adapted to the shape of the two side walls of the connecting seat 113 for connection and fixation, which helps to strengthen the connection between the first bracket 140 and the connecting seat 113. The first main section 140a and the first bending section 140b can be integrally formed, which is easier to process and form. Of course, the first main section 140a and the first bending section 140b can also be connected and fixed detachably or non-detachably after separate molding.

[0202] In addition, the container body 111 can be configured as a container structure with a bottom so as to smoothly receive the powder to be tested that circulates from top to bottom. At this time, the container body 111 is configured to be movable, and during the movement, it has a receiving state with the inlet end facing upward, and a dumping state with the inlet end facing downward. The receiving container 110 may also include a power mechanism that drives the container body 111 to move, so that the container body 111 can switch between the receiving state and the dumping state. When the movement is to the receiving state, the powder to be tested enters the inlet end of the container body 111 from top to bottom, and the weighing unit 131 can measure the weight of the receiving container 110 as a whole. When the movement is to the dumping state, the container body 111 can dump the received powder after weight measurement downward to the inlet end of the brewing module. In this way, the receiving and transfer of the powder to be tested is completed.

[0203] Alternatively, in one embodiment, the container body 111 is provided with a material delivery channel 111a along the vertical direction; the receiving container 110 also includes an opening and closing piece, which is movably provided on the connecting seat 113 along the first horizontal direction, so as to have a closed position that can be moved toward the container body 111 to cut off the material delivery channel 111a, and an open position that can be moved away from the container body 111 to conduct the material delivery channel 111a; the weighing module also includes a driving device 120, which is fixed relative to the fixed carrier and drives the opening and closing piece.

[0204] Specifically, the container body 111 is generally cylindrical, with the space within the cylinder directly defining a feed channel 111a. The feed channel 111a can extend in a direction as needed, for example, along the direction of gravity or in a direction inclined relative to gravity. Of course, the feed channel 111a can be configured as a straight channel structure or, depending on actual needs, as a channel structure that is at least partially curved.

[0205] The opening and closing member can be positioned anywhere within the feed channel 111a, for example, at the inlet end, at the outlet end, or anywhere between the inlet and outlet ends of the feed channel 111a. For example, as shown in Figures 4 and 5 , the opening and closing member is positioned at the outlet end of the feed channel 111a and externally positioned within the container body 111. The opening and closing member is generally plate-shaped. The shape and dimensions of the portion of the opening and closing member that covers the outlet end of the feed channel 111a can be adapted to that of the outlet end.

[0206] There is no restriction on the movement of the opening and closing member relative to the container body 111:

[0207] In one embodiment, the opening and closing member can be flipped relative to the container body 111. Specifically, one end of the opening and closing member is rotatably connected to an edge of the outlet end of the material delivery channel 111a, and the other end of the opening and closing member can flip to a closed position toward the other edge of the outlet end of the material delivery channel 111a, and flip to an open position toward the other edge of the outlet end of the material delivery channel 111a.

[0208] Alternatively, in the embodiment shown in Figures 4 and 5, the opening and closing member can be translated relative to the container body 111. Specifically, the opening and closing member is offset to one side of the outlet end of the material delivery channel 111a and can be translated to a closed position toward the other side of the outlet end of the material delivery channel 111a, and can be translated to an open position away from the other side of the outlet end of the material delivery channel 111a.

[0209] The configuration of the drive mechanism 120 is related to the movement of the opening and closing member. The drive mechanism 120 includes at least a drive assembly, which is operatively connected to the opening and closing member to drive the opening and closing member to move back and forth between a closed position and an open position. The fixing portion 132 can be connected to a portion of the drive assembly that is not connected to the opening and closing member and is relatively fixed, such as the housing structure.

[0210] Alternatively, please refer to Figures 6 to 9 for details. In one embodiment, the driving device 120 includes a docking seat 121 and a driving assembly. The docking seat 121 is connected and fixed to the fixing portion 132. Specifically, in one application, the fixing portion 132 is arranged at one end of the top of the docking seat 121; the driving assembly is arranged on the docking seat 121 and is detachably connected to the opening and closing member, wherein when the driving assembly is connected and drives the opening and closing member to move to the open position, it can continue to maintain connection with the opening and closing member; after the driving assembly is connected and drives the opening and closing member to move to the closed position, the driving assembly is disconnected from the opening and closing member and separated from each other, and is in a non-contact state. A receiving cavity can be formed inside the docking seat 121. The docking seat 121 can be set to be closed, and the driving assembly is at least partially sealed and accommodated in the receiving cavity. The setting of the docking seat 121 can provide a connection space for the fixing portion 132 that is independent of the driving assembly, and also provide a stable and sealed receiving space for the driving assembly.

[0211] It should be emphasized that the weighing device 130 is roughly cantilevered. By positioning the drive assembly at the docking station 121 and connecting the fixing portion 132 to the docking station 121, the drive assembly directly applies downward force to the fixing portion 132, bearing only the container body 111 and the powder contained therein. Compared to conventional solutions in which the drive assembly and container body 111 are integrally positioned within the weighing unit 131, the weighing unit 131 in this design bears virtually no weight of the drive assembly. This effectively prevents the heavy drive assembly from placing a load on the weighing unit 131, thereby ensuring that the weighing results of the weighing unit 131 in this design are more sensitive and accurate. Furthermore, vibrations generated by the drive assembly during operation are effectively prevented from causing measurement deviations in the weighing unit 131, thereby ensuring that the weighing process in this design is more stable and efficient.

[0212] Furthermore, in one embodiment, the opening and closing member moves translationally along the first horizontal direction toward and away from the container body 111, and the projection of the weighing device 130 on the horizontal plane is completely located within the projection plane of the connecting seat 113 on the horizontal plane; the driving assembly includes a driver 122 and a rotating member 123, the driver 122 and the fixing portion 132 are both connected and fixed to the docking seat 121, the driver 122 is driven and connected to the rotating member 123, one of the connection points between the rotating member 123 and the opening and closing member is provided with a guide groove 114b extending along the second horizontal direction, and the other is provided with a guide protrusion 123a, and during the rotation of the rotating member 123, the guide protrusion 123a has a first stroke section that contacts the guide groove 114b and slides along the guide groove 114b, and a second stroke section that disengages from the guide groove 114b.

[0213] The driver 122 performs a rotational output and can be a motor or a combination of a motor and a transmission assembly. The transmission assembly can be, for example, a gear set, a worm gear mechanism, or the like. The rotating member 123 is connected to the rotational output shaft of the driver 122 so that, under the rotational drive of the rotational output shaft of the driver 122, the rotating member 123 can be driven by the driver 122 to rotate in the same direction, ultimately driving the guide protrusion 123a to slide against and contact the guide groove 114b. Since the guide groove 114b extends along the second horizontal direction, the rotational motion of the rotating member 123 can be converted into a translational motion that drives the guide groove 114b along the first horizontal direction and the guide protrusion 123a of the rotating member 123 within the guide groove 114b toward the second horizontal direction, ultimately achieving the purpose of driving the opening and closing member to perform translational movement along the first horizontal direction. The second horizontal direction in which the guide groove 114b extends is perpendicular to the first horizontal direction of the translational motion of the guide groove 114b. In the above description, when the guide protrusion 123a is in the first stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a mutually contacting and connected state, and the driving force of the driver 122 can ultimately be transmitted to the opening and closing member, thereby switching the opening and closing member between the open position and the closed position. When the guide protrusion 123a is in the second stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a disconnected state, and the driving force of the driver 122 cannot be transmitted to the opening and closing member, and the opening and closing member is locked in the current position (specifically, the closed position). At this time, the driving device 120 and the receiving container 110 remain substantially separated. The driving device 120 independently applies force to the fixing portion 132 of the weighing device 130, and the receiving container 110 independently applies force to the weighing portion 131 of the weighing device 130. This helps to prevent the gravity of the driving device 120 from affecting the measured weight of the material received by the receiving container 110, thereby further helping to improve the weighing accuracy and optimize the weighing effect.

[0214] It should be noted that when the guide protrusion 123a is in the first travel segment, the guide protrusion 123a is in sliding engagement with at least the sidewall of the guide groove 114b. Optionally, the top of the guide protrusion 123a can be in sliding engagement with the bottom wall of the guide groove 114b, thereby ensuring a smoother sliding connection between the guide protrusion 123a and the guide groove 114b. Alternatively, the top of the guide protrusion 123a can be spaced apart from the bottom wall of the guide groove 114b, thereby ensuring that the connecting base 113 remains suspended above the guide protrusion 123a and the docking base 121. In this manner, apart from the weighing portion 131 in direct contact with the container body 111 and the fixing portion 132 in direct contact with the docking base 121, no other components come into contact with the weighing device 130. This minimizes any other contact during weighing by the weighing device 130, thereby ensuring accurate weighing.

[0215] In a preferred embodiment, the guide protrusion 123a may include a boss and a ring sleeved on the outer circumference of the boss, wherein the ring can be sleeved on the boss and rotate around the boss, and the ring contacts and drives the opening and closing part to move in the guide groove 114b. The friction force formed by the contact of the ring driving the guide groove 114b is converted into rolling friction force, thereby reducing the friction generated and preventing wear and friction noise caused by long-term contact friction.

[0216] Furthermore, referring to Figures 6 to 9 , in one embodiment, the outer top wall of the docking base 121 is provided with a circular restriction hole 121f extending therethrough, and an arcuate groove 121a surrounding the outer periphery of the restriction hole 121f. Specifically, the bottom of the docking base 121 forms a partition, and the rotating member 123 and the driver 122 are disposed on the upper and lower sides of the partition, respectively. The driver 122 is connected to the rotating member 123 via the restriction hole 121f provided through the partition. The arc length of the arc groove 121a is not less than the arc length corresponding to the guide protrusion 123a when performing the first stroke segment; the rotating member 123 includes a rotating arm 123c and a rib 123d protruding downward from the bottom end of the rotating arm 123c to extend into the arc groove 121a, and a rotating boss 123e is protruded from one radial end of the rotating arm 123c toward the docking seat 121, and the rotating boss 123e is rotatably connected to the limiting hole 121f of the docking seat 121, and the other radial end of the rotating arm 123c is protruded with a guide protrusion 123a facing away from the docking seat 121, and the rib 123d slides along the side groove wall of the arc groove 121a; the driver 122 is accommodated in the docking seat 121, and the drive shaft extends upward from the through limiting hole 121f to the outside. In order to enhance the structural strength of the rotating arm 123 c , in one embodiment, the rotating member 123 may further include fan-shaped plates 123 b extending from both sides of the rotating arm 123 c .

[0217] In one embodiment of the present application, the rotating boss 123e is mounted on the drive shaft of the driver 122 and is located above the limiting hole 121f. The outer diameter of the rotating boss 123e is larger than the aperture of the limiting hole 121f, so that the rotating boss 123e can cover the area above the limiting hole 121f. In another embodiment, the rotating boss 123e extends into the limiting hole 121f, wherein the outer diameter of the rotating boss 123e substantially matches the aperture of the limiting hole 121f, so that the rotating boss 123e fills the entire limiting hole 121f.

[0218] Specifically, the arcuate groove 121a can be arranged along the entire circumference of the rotation axis of the rotating member 123, so that the rib 123d can slide along the entire circumference of the side groove wall of the arcuate groove 121a, thereby achieving unidirectional and full-circumferential rotation of the rotating member 123. Alternatively, the arcuate groove 121a can be arranged partially along the circumference of the rotation axis of the rotating member 123, so that when the rib 123d slides along the side groove wall of the arcuate groove 121a, the rotating member 123 can achieve unidirectional rotation of a limited arc length.

[0219] The plate 123b, rotating arm 123c, rib 123d, and guide protrusion 123a of the rotating member 123 can be integrally formed, or they can be formed separately and then removably or non-removably connected and fixed. The provision of the rotating arm 123c and rib 123d helps to reduce material consumption of the rotating member 123 and prevents excessive sliding connection between the rotating member 123 and the guide groove 114b and the arcuate groove 121a, which would increase sliding losses.

[0220] It should be noted that, in order to allow the guide protrusion 123a to extend into and out of the guide groove 114b, in one embodiment, the outer peripheral surface of the guide protrusion 123a and / or the corresponding side groove wall of the guide groove 114b can be configured as an inclined straight surface or an arcuate surface to provide smooth guidance. Alternatively, in one embodiment, the rotating member 123 can be telescopically mounted on the docking seat 121 relative to its own rotational axis, and the arcuate groove 121a can be configured with a gradually increasing depth in the portion corresponding to the second stroke segment.

[0221] As can be seen from the above, the rotation of the rotating member 123 simultaneously drives the guide protrusion 123a to slide along the guide groove 114b, and simultaneously drives the rib 123d to slide along the arcuate groove 121a. Therefore, in order to limit the rotation angle range of the rotating member 123, the sliding strokes of the rotating member 123 itself, the guide protrusion 123a and the guide groove 114b, and the sliding strokes of the rib 123d and the arcuate groove 121a can be specifically configured.

[0222] In view of the above, referring to FIG10 , when the opening and closing member translates along the first horizontal direction, the guide slot 114b extends substantially along a second horizontal direction perpendicular to the first horizontal direction. In this case, the guide slot 114b includes at least a first side slot wall and a second side slot wall disposed opposite each other in the first horizontal direction, both of which extend along the second horizontal direction. If the distance between the first side slot wall and the second side slot wall, i.e., the slot length of the guide slot 114b, is k, and the length of the guide protrusion 123a of the rotating member 123 along the first horizontal direction, i.e., the radius of the guide protrusion 123a when the guide protrusion 123a is cylindrical, is r, then k is greater than twice r. This means that when the guide protrusion 123a is located between the first side slot wall and the second side slot wall, it can only abut against the first side slot wall or the second side slot wall. When the guide protrusion 123a abuts against the first side slot wall or the second side slot wall, the gap between the guide protrusion 123a and the other slot wall is t. This helps to avoid excessive friction interference between the guide protrusion 123a and the guide groove 114b, ensuring that the guide protrusion 123a can slide along the guide groove 114b.

[0223] If the rotation radius of the guide protrusion 123a, that is, the distance from the rotation center of the rotating member 123 to the center of the guide protrusion 123a is L, and the moving path length of the rotating member 123 driving the opening and closing member is S, then S=2L-k.

[0224] 11 to 14 , if it is defined that when the guide protrusion 123a slides in the guide groove 114b to the first limit position, the opening and closing member is in the open position; when the guide protrusion 123a slides in the guide groove 114b to the second limit position, the opening and closing member is in the closed position.

[0225] In one embodiment, the driver 122 is configured to stop operating immediately when the guide protrusion 123a is driven to move to the first limit position or the second limit position.

[0226] Alternatively, in one embodiment, the driver 122 is configured to continue operating when the guide protrusion 123a is moved to the first limit position or the second limit position, and the driver 122 stops operating after the guide protrusion 123a continues to slide to a certain stroke.

[0227] It should be noted that there are multiple ways to stop the control driver 122:

[0228] In one embodiment, the target rotation angle can be determined by calculating the rotation angle range of the driver 122. For example, based on the structural design parameters of the guide groove 114b, the guide protrusion 123a, etc., the required rotation angle for the guide protrusion 123a to move to the first limit position or the second limit position is calculated, and then the target rotation angle is used as the target rotation angle to control the driver 122 to stop operation.

[0229] Alternatively, in one embodiment, the rotation angle range of the rotating member 123 may be determined by limiting the rotation angle range of the rotating member 123. Specifically, the rotation angle range of the rotating member 123 may be set to be greater than 180° and less than 360°. When the rotation angle range is exceeded, the driver 122 is controlled to stop operating.

[0230] Alternatively, in one embodiment, an additional stop structure can be provided to mechanically stop the rotation of the rotating member 123 or the output shaft. Specifically, the stop structure can be provided, for example, within the guide groove 114b at a predetermined position corresponding to the sliding path of the guide protrusion 123a, or on the docking station 121 at a predetermined position corresponding to the rotation path of the rotating member 123.

[0231] Alternatively, in one embodiment, a sensor device can be provided to determine the active position of the guide protrusion 123a and / or the rotating member 123. Specifically, in conjunction with Figures 6 and 9, in one embodiment, the docking station 121 is provided with a position sensor 121b protruding from the side of the arc-shaped groove 121a, and the position sensor 121b is provided with a sensing portion 121c. The sensing portion 121c can be provided protrudingly on the side surface of the position sensor 121b facing the arc-shaped groove 121a, and the sensing portion 121c and the position sensor 121b can be integrally formed, or can be separately formed and then connected and fixed in a detachable or non-detachable manner. The sensing portion 121c can specifically be provided with a through groove 121d. The through groove 121d is adapted to be provided at the corresponding outer periphery of the rotating member 123. The through groove 121d can, to a certain extent, limit the rotation of the rotating member 123 along its rotation axis without affecting the rotation of the rotating member 123. The rotating member 123 is provided with a triggering portion corresponding to the sensing portion 121 c. When the triggering portion approaches the sensing portion 121 c, the position sensor 121 b is triggered to generate a sensing signal.

[0232] As shown in Figure 15, two of the aforementioned sensing parts 121c or position sensors 121b can be provided at intervals. Taking two sensing parts 121c as an example, the two sensing parts 121c correspond to the open position and closed position of the opening and closing member, respectively. The two sensing parts 121c are provided at intervals on the rotating periphery of the trigger portion of the rotating member 123. The driver 122 drives the rotating member 123 to rotate, and by switching the driver 122 between forward and reverse rotation, the trigger portion switches back and forth between the two sensing parts 121c.

[0233] It should be noted that when the driver 122 is configured to continue to operate for a certain distance after driving the guide protrusion 123a to the first or second limit position before stopping, in one embodiment, the guide protrusion 123a can be configured to disengage from the guide groove 114b after sliding for the distance, thereby completing the clutch connection between the rotating member 123 and the opening and closing member. There are various ways to disengage, such as gradually reducing the groove depth of the corresponding groove section of the guide groove 114b so that the guide protrusion 123a is gradually pushed out of the guide groove 114b; or the guide groove 114b can be configured to be open at both ends in the second horizontal direction so that the guide protrusion 123a can disengage from the guide groove 114b outwardly from the open ends.

[0234] Furthermore, based on the above, and in conjunction with Figures 4 and 5 , in one embodiment, the connecting base 113 is provided with a mounting slot 113a, within which a guide rod 115 is disposed, extending along a first horizontal direction. The opening and closing member may specifically include a cover plate 112 and a slider 114. The cover plate 112 covers the notch of the mounting slot 113a and is provided with a mounting hole 112a extending therethrough and communicating with the mounting slot 113a. The slider 114 is received within the mounting slot 113a and partially extends outward from the mounting hole 112a. The slider 114 is fixed relative to the cover plate 112. The portion of the slider 114 within the mounting slot 113a is provided with a guide hole 114a for slidably engaging with the guide rod 115. The portion of the slider 114 extending outside the mounting slot 113a is provided with the guide slot 114b or the guide protrusion 123a. The number of guide rods 115 provided may be one or multiple guide rods 115 extending side by side in the same direction. The guide holes 114 a are suitable for adaptively adjusting the number and positions of the guide rods 115 .

[0235] Of course, in one embodiment, the opening and closing member may specifically include a cover plate 112 and a slider 114, and the slider 114 is fixedly connected to one side of the cover plate 112 covering the mounting groove 113a and is not exposed on the outside of the cover plate 112. At this time, the above-mentioned guide groove 114b or the guide protrusion 123a may be provided on the side of the cover plate 112 facing away from the mounting groove 113a.

[0236] In addition, in one embodiment, the weighing device 130 is suspended in the inner cavity of the housing and is roughly cantilevered. When the weighing module is not receiving any material, the counterweight of the weighing part 131 of the weighing device 130 is set to be equivalent to the counterweight of the fixed part 132, or the counterweight of the weighing part 131 of the weighing device 130 is set to be smaller than the counterweight of the fixed part 132. That is, when the weighing module is not receiving any material, the structural design is such that the weighing part 131 and the fixed part 132 of the weighing device 130 are balanced with each other, or at least the weighing part 131 is smaller, so as to avoid the unbalanced force between the weighing part 131 and the fixed part 132 of the weighing device when not weighing, which may cause the cantilever weighing device to deflect, and easily reduce the weighing accuracy of the weighing device after long-term use.

[0237] To further facilitate installation of the weighing device, referring to Figure 15 , in one embodiment, the weighing module further includes a second bracket 150, which includes a second main section 150a and two second bent sections 150b. The second main section 150a extends along the second horizontal direction and is connected and fixed to the fixing portion 132. The two second bent sections 150b are disposed on opposite sides of the second main section 150a in the second horizontal direction and extend in a vertical direction. The two second bent sections 150b are respectively connected and fixed to the side walls of the drive device 120. The second bracket 150 can be configured in a plate or sheet shape, making it easier to fold to fit the shape of the drive device 120 and helping to reduce the weight of the entire device.

[0238] Furthermore, in one embodiment, the weighing module also includes a second connecting member 160. One of the second bracket 150 and the docking seat 121 is provided with a second sliding groove 121e, while the other is provided with a second sliding protrusion 151 that slidably engages with the second sliding groove 121e. When the second bracket 150 and the docking seat 121 are slidably connected and in place, the second connecting member 160 connects and secures the second bracket 150 and the docking seat 121. The second main section 150a extends along the second horizontal direction, increasing the connection area with the fixing portion 132 in the second horizontal direction and strengthening the connection between the second bracket 150 and the fixing portion 132. When the drive device 120 is connected to the docking seat 121 and the second bracket 150, the two second bent sections 150b can adapt to the shape of the side walls of the docking seat 121 to secure the connection, thereby strengthening the connection between the second bracket 150 and the docking seat 121. The second main section 150a and the second bent section 150b can be integrally formed, making it easier to process and form. Of course, the second main section 150a and the second bent section 150b can also be connected and fixed detachably or non-detachably after being separately formed.

[0239] A limiting groove 141 can be provided on the side of the first bracket 140 facing away from the connecting seat 113, and the weighing part of the weighing device can be limitedly installed in the limiting groove 141 and connected and fixed to the first bracket 140 through a connecting piece. The setting of the second sliding protrusion 151 and the second sliding groove 121e can be specifically referred to the setting of the above-mentioned first sliding protrusion and the second sliding groove 121e, and no further details are given. The setting of the second sliding protrusion 151 and the second sliding groove 121e helps to achieve the plug-in and unplug fixation between the second bracket 150 and the docking seat 121, and the sliding connection direction between the second sliding protrusion 151 and the second sliding groove 121e is different from the weighing direction of the weighing part and the counterweight direction of the fixing part 132, so as to avoid excessive influence on the weighing function of the weighing device. Similarly, the setting of the above-mentioned connecting piece and the second connecting piece 160 can be specifically referred to the above-mentioned first connecting piece, and no further details are given.

[0240] In view of the above embodiments, in a further solution, the present application further specifically provides a weighing module, which includes a weighing device 130, a fixed carrier, a receiving container 110, and a driving device 120. The weighing device 130 extends laterally along a first horizontal direction and includes a fixing portion 132 and a weighing portion 131 located at both ends of the first horizontal direction; the fixing portion 132 of the weighing device 130 is suspended from the fixed carrier; the receiving container 110 is fixed to the weighing portion 131, and the receiving container 110 and the fixed carrier are arranged at both ends of the weighing device 130 along the first horizontal direction; the driving device 120 is arranged on the fixed carrier and supports the weighing device 130 together with the fixed carrier; the projections of the weighing device 130, the driving device 120, and / or the fixed carrier in a vertical direction perpendicular to the first horizontal direction at least partially overlap.

[0241] That is, the projection of the weighing device 130 in the vertical direction is the first projection, the projection of the driving device 120 in the vertical direction is the second projection, and the projection of the fixed carrier in the vertical direction is the third projection, then the first projection and the second projection at least partially overlap; and / or the first projection and the third projection at least partially overlap.

[0242] Specifically in one embodiment, when the connecting seat 113 is provided as described above, the projection of the connecting seat 113 in the vertical direction is the fourth projection, then the first projection and the fourth projection at least partially overlap, and preferably, the first projection completely falls within the fourth projection and is completely covered by the fourth projection.

[0243] The above arrangement helps to make the orientation layout between the weighing device 130 and the driving device 120, and between the weighing device 130 and the docking seat of the receiving container 110 more reasonable, and the force more balanced, which helps to stabilize the overall structure of the weighing module.

[0244] It should be emphasized that the beverage preparation equipment in the present application can be a bean grinder for grinding coffee beans, the weighing module can be arranged in the coffee bean grinder, the grinder is provided with a grinding module, the weighing module and the setting are matched with the grinding module of the grinder, the installation and control method of the weighing module in the grinder are the same as above, and the powder material weighed by the weighing module can be received by the powder bowl and then brewed manually.

[0245] The third application example:

[0246] Referring to Figures 3-4, 6, 8, and 10-20, this application provides a beverage preparation device comprising a body and a weighing module. The body comprises at least a housing defining an inner cavity, a grinding module disposed within the inner cavity, and a brewing module, the body being provided with a mating structure. Furthermore, to enable intelligent and automatic operation of the beverage preparation device, the body may further include a control device housed within the inner cavity of the housing and / or a display module at least partially exposed on the outer wall of the housing.

[0247] This design does not limit the specific type of beverage preparation device; it can be any device or product that can extract and brew materials to ultimately produce a beverage. Specifically, the beverage preparation device can be, but is not limited to, a coffee machine, a soymilk maker, a bean grinder, a food processor, etc. Correspondingly, the materials involved in this application can be beans such as coffee beans and soybeans. For ease of understanding, the following embodiments are described using a coffee machine as an example of a beverage preparation device, where the materials include coffee beans that have not been ground by a grinding module, as well as coffee powder obtained after being ground by a grinding module.

[0248] The grinding module may include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder defines a grinding chamber; the grinding mechanism includes, for example, a movable cutting tool and a first drive assembly that actuates the cutting tool. The cutting tool can be designed with a desired shape and suitable motion to facilitate puncturing, grinding, stirring, and other crushing operations on granular materials such as coffee beans. Examples of these tools include bayonets and blade discs. The outlet of the grinding module refers to the outlet of the grinding cylinder.

[0249] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee beverage. The brewing mechanism is mainly configured as a pressing mechanism, a heating mechanism and / or a water supply component according to different brewing requirements. In addition, the brewing mechanism can also be configured as, but is not limited to, a refrigeration mechanism and / or a milk supply component, etc. according to actual needs, to obtain different types of coffee beverages. The inlet end of the brewing module refers to the inlet end of the brewing cylinder.

[0250] In view of the above, the following is specifically described by taking an example in which a beverage preparation device includes a grinding module and a brewing module, and a weighing module is arranged between the outlet end of the grinding module and the inlet end of the brewing module:

[0251] In conjunction with Figures 17 and 18 , the present application further provides a weighing module, which is used in the aforementioned beverage preparation device and is specifically housed within the inner cavity of the housing. The weighing module can be disposed within the housing between the outlet of the grinding module and the inlet of the brewing module. The inlet of the weighing module is operably connected to the outlet of the grinding module, and the outlet of the weighing module is operably connected to the inlet of the brewing device. When the inlet of the weighing module is connected to the outlet of the grinding module and disconnected from the inlet of the brewing device, the weighing module can receive and store coffee grounds discharged from the outlet of the grinding module, while simultaneously or with a delayed weighing function, operating in a weighing mode. When the inlet of the weighing module is connected to the outlet of the grinding module and the outlet of the weighing module is connected to the inlet of the brewing device, the weighing module primarily serves as a powder transfer device and does not perform a weighing function, operating in a non-weighing mode.

[0252] When the weighing module is used in a beverage preparation device, it is placed in the machine body as a modular component. The plug-in structure of the weighing module and the matching structure of the machine body can be quickly disassembled and assembled. When the weighing module is installed in the housing and located between the grinding module and the brewing module, the current position of the weighing module constitutes the preset installation position:

[0253] In one embodiment, when the weighing module is removed from the machine body, the pre-set installation position becomes vacant, creating a gap between the grinding module and the brewing module. Optionally, a plug-in structure can also be provided on the grinding module and / or the brewing module. Based on this plug-in structure, the grinding module and / or the brewing module can be plugged into a mating structure on the machine body to replace the pre-set installation position, thereby placing the brewing module and the grinding module as close together as possible to prevent powder from scattering during transfer.

[0254] Alternatively, in one embodiment, a detachable or integral, deformable connecting structure can be provided between the grinding module and / or the brewing module. When the weighing module is installed in the housing, the connecting structure compresses and deforms; conversely, when the weighing module is removed from the housing, the connecting structure extends and deforms, connecting the outlet of the grinding module with the inlet of the brewing module, thereby preventing a gap from forming between the grinding module and the brewing module. The connecting structure can be a soft rubber channel, etc., and its specific form is not limited.

[0255] Based on this, further, in one embodiment, the beverage preparation device can also identify whether the weighing module is installed in the casing through its own preset or externally connected control device, combined with one or several sensor devices, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0256] In view of the above, it can be seen that the beverage preparation device and / or the weighing module are pre-set with optional weighing mode and non-weighing mode. In actual application, the beverage preparation device can adjust whether the whole machine is currently in weighing mode or non-weighing mode by manual setting based on, for example, preset buttons. Among them, when the whole machine is in non-weighing mode, the weighing component can be in an uninstalled state when it is removed from the inside of the casing, or it can be in an installed state installed in the casing. When the weighing module is in an installed state installed in the casing, the weighing module can be used as a transfer mechanism for conveying powder from the grinding module to the brewing module as described above. The weighing module is set to a normally open form, which is equivalent to a connecting pipeline. When the powder is conveyed from the grinding module to the brewing module, the powder passes through the weighing module freely and unobstructed.

[0257] The weighing module includes a receiving container 110, a driving device 120, a weighing device 130, and a stopper 600. The receiving container 110 includes a container body 111 and an opening and closing member. The container body 111 is provided with a material feeding channel 111a. The opening and closing member is movably arranged relative to the container body 111, so as to have an open position for conducting the material feeding channel 111a and a closed position for closing the material feeding channel 111a. The driving device 120 includes a main body and a power output part movably arranged relative to the main body, and the power output part is drivingly connected to the opening and closing member. The weighing device 130 includes a weighing part 131 connected to the receiving container 110. The stopper 600 is at least provided to stop the side of the power output part close to the container body 111.

[0258] In the technical solution provided in the present application, when the driving device 120 drives the opening and closing parts to move to the closed position, the container body 111 can receive the powder to be tested, for example, discharged through the grinding module, and the weighing device 130 can simultaneously or delayedly measure the weight of the powder to be tested received by the container body 111; when the weight measurement operation is completed, the driving device 120 drives the opening and closing parts to move to the open position, and the powder received by the container body 111 is discharged through its own outlet end. Since the baffle 600 is at least arranged between the container body 111 and the power output part of the driving device 120, the powder discharged from the container body 111 is not easy to fly to the power output part, thereby effectively avoiding the powder from causing interference such as blockage of the power output part, thereby ensuring the normal and efficient operation of the driving device 120.

[0259] It should be noted that when the weighing module is used in a beverage preparation device, it can be assembled into the body in any suitable posture according to actual needs. For ease of understanding, in the following embodiments, the beverage preparation device as a whole and its components have approximately perpendicular horizontal and vertical directions. The vertical direction is also approximately the direction of gravity. The horizontal direction is any suitable direction on the horizontal plane, which can specifically be a first horizontal direction and a second horizontal direction arranged in a cross pattern. The angle between the first horizontal direction and the second horizontal direction can be set to approximately 90°.

[0260] In this design, the container body 111 is generally cylindrical, with the space within the cylinder directly defining a feed channel 111a. The feed channel 111a can extend in a direction as needed, for example, vertically or in a direction inclined relative to the vertical. Of course, the feed channel 111a can be configured as a straight channel structure or, depending on actual needs, as a channel structure that is at least partially curved.

[0261] The opening and closing member can be positioned anywhere within the feed channel 111a, for example, at the inlet end, at the outlet end, or anywhere between the inlet and outlet ends of the feed channel 111a. For example, as shown in Figures 3 and 4 , the opening and closing member is positioned at the outlet end of the feed channel 111a and externally positioned within the container body 111. The opening and closing member is generally plate-shaped. The shape and dimensions of the portion of the opening and closing member that covers the outlet end of the feed channel 111a can be adapted to that of the outlet end.

[0262] There is no restriction on the movement of the opening and closing member relative to the container body 111:

[0263] In one embodiment, the opening and closing member can be flipped relative to the container body 111. Specifically, one end of the opening and closing member is rotatably connected to an edge of the outlet end of the material delivery channel 111a, and the other end of the opening and closing member can flip to a closed position toward the other edge of the outlet end of the material delivery channel 111a, and flip to an open position toward the other edge of the outlet end of the material delivery channel 111a.

[0264] Alternatively, in the embodiment shown in Figures 3 and 4, the opening and closing member can be translated relative to the container body 111. Specifically, the opening and closing member is offset to one side of the outlet end of the material delivery channel 111a and can be translated to a closed position toward the other side of the outlet end of the material delivery channel 111a, and can be translated to an open position away from the other side of the outlet end of the material delivery channel 111a.

[0265] The configuration of the drive mechanism 120 is related to the movement of the opening and closing member. The drive mechanism 120 includes at least a drive assembly, which is operatively connected to the opening and closing member to drive the opening and closing member to move back and forth between a closed position and an open position. The fixing portion 132 can be connected to a portion of the drive assembly that is not connected to the opening and closing member and is relatively fixed, such as the housing structure.

[0266] Alternatively, please refer to Figures 19 and 6 to 8 for details. In one embodiment, the driving device 120 includes a docking seat 121 and a driving assembly. The docking seat 121 is connected and fixed to a fixing portion 132. Specifically, in one application, the fixing portion 132 is provided at one end of the top of the docking seat 121. The driving assembly is provided on the docking seat 121 and is detachably connected to the opening and closing member. When the driving assembly is connected and drives the opening and closing member to move to the open position, it can continue to maintain connection with the opening and closing member. After the driving assembly is connected and drives the opening and closing member to move to the closed position, the driving assembly is disconnected from the opening and closing member and separated from each other, entering a non-contact state. A receiving cavity can be formed inside the docking seat 121. The docking seat 121 can be configured to be closed, with the driving assembly at least partially sealed and accommodated in the receiving cavity. The provision of the docking seat 121 can provide a connection space for the fixing portion 132 that is independent of the driving assembly, while also providing a stable and sealed accommodation space for the driving assembly.

[0267] It can be understood that the weighing device 130 may only include the weighing part 131. Or the weighing device 130 is roughly cantilevered in the first horizontal direction, and includes a fixed part 132 and a weighing part 131 connected to each other. The fixed part 132 is connected to a fixed carrier in the beverage preparation equipment. The fixed carrier may be, but is not limited to, one or more of a housing, a grinding module, and a brewing module. The weighing part 131 is connected and fixed to the receiving container 110. The fixed part 132 and the weighing part 131 may be integrally formed, or they may be separately formed and then connected detachably or non-detachably.

[0268] Since the weighing device 130 is roughly in the shape of a cantilever extending along the first horizontal direction, its weighing part 131 and fixing part 132 are respectively arranged at the two ends of the first horizontal direction. Therefore, in actual application, please refer to Figures 16 and 17, the weighing part 131 is connected to the receiving container 110, and at least the part of the receiving container 110 connected to the weighing part 131 can be suspended vertically below the weighing part 131, or it can be supported vertically above the weighing part 131. Similarly, the fixing part 132 is connected to the driving device 120, and the part of the driving device 120 that can be connected to the fixing part 132 can be connected vertically below the fixing part 132, or it can be connected vertically above the fixing part 133.

[0269] When at least the portion of the receiving container 110 connected to the weighing unit 131 is supported vertically above the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing pressure changes. When at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing tension changes.

[0270] The portion where the receiving container 110 is connected to at least the weighing part 131, and the portion where the driving device 120 / fixed carrier is connected to at least the fixing part 132, can be arranged on both sides of the weighing device 130 in the vertical direction, or can be located on the same side of the weighing device 130 in the vertical direction.

[0271] However, for ease of understanding, the following embodiments are described as follows, assuming that at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, and at least the portion of the driving device 120 connected to the fixing unit 132 is connected vertically below the fixing unit 132. Specifically, as shown in FIG8 , the connecting base 113 is suspended below the weighing unit 131 and is fixedly connected to the lower end of the weighing unit 131.

[0272] In the above embodiment, by arranging the drive assembly at the docking seat 121 and connecting the fixing portion 132 to the docking seat 121, the drive assembly directly applies a downward force to the fixing portion 132, and only bears the direct downward force exerted by the container body 111 and the powder contained in the container body 111 on the weighing portion 131. Compared to the conventional solution in which the drive assembly and the container body 111 are integrally arranged in the weighing portion 131, the weighing portion 131 in this design does not bear the weight of the drive assembly. In this way, the heavy drive assembly can be effectively prevented from causing a force burden on the weighing portion 131, thereby ensuring that the weighing results of the weighing portion 131 in this design are more sensitive and accurate. It also effectively prevents the vibration generated by the drive assembly during operation from causing measurement deviations in the weighing portion 131, thereby ensuring that the weighing process of the weighing portion 131 in this design is more stable and effective.

[0273] Furthermore, in one embodiment, the receiving container 110 further includes a connecting seat 113 extending below the weighing device 130 and connected to the weighing device 130. The container body 111 and the weighing portion 131 are connected and fixed to the connecting seat 113. The opening and closing member is movably installed on the connecting seat 113 in a first horizontal direction close to and away from the container body 111. The projection of the weighing device 130 on the horizontal plane is completely located within the projection plane of the connecting seat 113 on the horizontal plane. The driving assembly includes a driver 122 and a rotating member 123. The driver 122 and the fixing portion 132 are both connected and fixed to the docking seat 121, and the driver 122 is drivingly connected to the rotating member 123. One of the connection points between the rotating member 123 and the opening and closing member is provided with a guide groove 114b extending along a second horizontal direction intersecting the first horizontal direction, and the other is provided with a guide protrusion 123a. During the rotation of the rotating member 123, the guide protrusion 123a has a first stroke section that contacts the guide groove 114b and slides along the guide groove 114b, and a second stroke section that disengages from the guide groove 114b.

[0274] The driver 122 performs a rotational output and can be a motor or a combination of a motor and a transmission assembly. The transmission assembly can be, for example, a gear set, a worm gear mechanism, or the like. The rotating member 123 is connected to the rotational output shaft of the driver 122 so that, under the rotational drive of the rotational output shaft of the driver 122, the rotating member 123 can be driven by the driver 122 to rotate in the same direction, ultimately driving the guide protrusion 123a to slide against and contact the guide groove 114b. Since the guide groove 114b extends along the second horizontal direction, the rotational motion of the rotating member 123 can be converted into a translational motion that pushes the guide groove 114b along the first horizontal direction and the movement of the protrusion of the rotating member 123 within the guide groove 114b toward the second horizontal direction, ultimately achieving the purpose of driving the opening and closing member to perform translational movement along the first horizontal direction. The second horizontal direction in which the guide groove 114b extends is perpendicular to the first horizontal direction of the translational motion of the guide groove 114b. In the above description, when the guide protrusion 123a is in the first stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a mutually contacting and connected state, and the driving force of the driver 122 can ultimately be transmitted to the opening and closing member, thereby switching the opening and closing member between the open position and the closed position. When the guide protrusion 123a is in the second stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a disconnected state, and the driving force of the driver 122 cannot be transmitted to the opening and closing member, and the opening and closing member is locked in the current position (specifically, the closed position). At this time, the driving device 120 and the receiving container 110 remain substantially separated. The driving device 120 independently applies force to the fixing portion 132 of the weighing device 130, and the receiving container 110 independently applies force to the weighing portion 131 of the weighing device 130. This helps to prevent the gravity of the driving device 120 from affecting the measured weight of the material received by the receiving container 110, thereby further helping to improve the weighing accuracy and optimize the weighing effect.

[0275] It should be noted that when the guide protrusion 123a is in the first travel segment, the guide protrusion 123a is in sliding engagement with at least the sidewall of the guide groove 114b. Optionally, the top of the guide protrusion 123a can be in sliding engagement with the bottom wall of the guide groove 114b, thereby ensuring a smoother sliding connection between the guide protrusion 123a and the guide groove 114b. Alternatively, the top of the guide protrusion 123a can be spaced apart from the bottom wall of the guide groove 114b, thereby ensuring that the connecting base 113 remains suspended above the guide protrusion 123a and the docking base 121. In this manner, apart from the weighing portion 131 in direct contact with the container body 111 and the fixing portion 132 in direct contact with the docking base 121, no other components come into contact with the weighing device 130. This minimizes any other contact during weighing by the weighing device 130, thereby ensuring accurate weighing.

[0276] In a preferred embodiment, the guide protrusion 123a may include a boss and a ring sleeved on the outer circumference of the boss, wherein the ring can be sleeved on the boss and rotate around the boss, and the ring contacts and drives the opening and closing part to move in the guide groove 114b. The friction force formed by the contact of the ring driving the guide groove 114b is converted into rolling friction force, thereby reducing the friction generated and preventing wear and friction noise caused by long-term contact friction.

[0277] Further, please refer to Figures 19 to 20 and Figures 6 to 7. In one embodiment, the outer top wall of the docking seat 121 is provided with a circular limiting hole 121f that passes through the inner wall and an arc-shaped groove 121a that is provided on the outer periphery of the limiting hole 121f. The arc length of the arc-shaped groove 121a is not less than the arc length corresponding to the guide protrusion 123a when performing the first stroke segment; the rotating member 123 includes a rotating arm 123c and a bottom end of the rotating arm 123c that protrudes downward to extend into the arc-shaped groove 121a. The rotating arm 123c includes a convex rib 123d. A rotating boss 123e is provided at one radial end toward the docking seat 121. The rotating boss 123e is rotatably connected to the limiting hole 121f of the docking seat 121. A guide protrusion 123a is provided at the other radial end of the rotating arm 123c, facing away from the docking seat 121. The rib 123d slides along the side walls of the arcuate groove 121a. The driver 122 is housed within the docking seat 121, and the drive shaft extends upward and outward from the through-limiting hole 121f. To enhance the structural strength of the rotating arm 123c, in one embodiment, the rotating member 123 may further include fan-shaped plates 123b extending from both sides of the rotating arm 123c. In practical applications, the plates 123b and the rotating arm 123c may be integrally formed, directly forming a single flat plate structure.

[0278] In one embodiment of the present application, the rotating boss 123e is mounted on the drive shaft of the driver 122 and is located above the limiting hole 121f. The outer diameter of the rotating boss 123e is larger than the aperture of the limiting hole 121f, so that the rotating boss 123e can cover the area above the limiting hole 121f. In another embodiment, the rotating boss 123e extends into the limiting hole 121f, wherein the outer diameter of the rotating boss 123e substantially matches the aperture of the limiting hole 121f, so that the rotating boss 123e fills the entire limiting hole 121f.

[0279] Specifically, the arcuate groove 121a can be arranged along the entire circumference of the rotation axis of the rotating member 123, so that the rib 123d can slide along the entire circumference of the side groove wall of the arcuate groove 121a, thereby achieving unidirectional and full-circumferential rotation of the rotating member 123. Alternatively, the arcuate groove 121a can be arranged partially along the circumference of the rotation axis of the rotating member 123, so that when the rib 123d slides along the side groove wall of the arcuate groove 121a, the rotating member 123 can achieve unidirectional rotation of a limited arc length.

[0280] The plate 123b, rotating arm 123c, rib 123d, and guide protrusion 123a of the rotating member 123 can be integrally formed, or they can be formed separately and then removably or non-removably connected and fixed. The provision of the rotating arm 123c and rib 123d helps to reduce material consumption of the rotating member 123 and prevents excessive sliding connection between the rotating member 123 and the guide groove 114b and the arcuate groove 121a, which would increase sliding losses.

[0281] It should be noted that, in order to allow the guide protrusion 123a to extend into and out of the guide groove 114b, in one embodiment, the outer peripheral surface of the guide protrusion 123a and / or the corresponding side groove wall of the guide groove 114b can be configured as an inclined straight surface or an arcuate surface to provide smooth guidance. Alternatively, in one embodiment, the rotating member 123 can be telescopically mounted on the docking seat 121 relative to its own rotational axis, and the arcuate groove 121a can be configured with a gradually increasing depth in the portion corresponding to the second stroke segment.

[0282] As can be seen from the above, the rotation of the rotating member 123 simultaneously drives the guide protrusion 123a to slide along the guide groove 114b, and simultaneously drives the rib 123d to slide along the arcuate groove 121a. Therefore, in order to limit the rotation angle range of the rotating member 123, the sliding strokes of the rotating member 123 itself, the guide protrusion 123a and the guide groove 114b, and the sliding strokes of the rib 123d and the arcuate groove 121a can be specifically configured.

[0283] In view of the above, referring to FIG10 , when the opening and closing member translates along the first horizontal direction, the guide slot 114b extends substantially along a second horizontal direction perpendicular to the first horizontal direction. In this case, the guide slot 114b includes at least a first side slot wall and a second side slot wall disposed opposite each other in the first horizontal direction, both of which extend along the second horizontal direction. If the distance between the first side slot wall and the second side slot wall, i.e., the slot width of the guide slot 114b, is k, and the length of the guide protrusion 123a of the rotating member 123 along the first horizontal direction, i.e., the radius of the guide protrusion 123a when the guide protrusion 123a is cylindrical, is r, then k is greater than twice r. This means that when the guide protrusion 123a is located between the first side slot wall and the second side slot wall, it can only abut against the first side slot wall or the second side slot wall. When the guide protrusion 123a abuts against the first side slot wall or the second side slot wall, the gap between the guide protrusion 123a and the other side slot wall is t. This helps to avoid excessive friction interference between the guide protrusion 123a and the guide groove 114b, ensuring that the guide protrusion 123a can slide along the guide groove 114b.

[0284] If the rotation radius of the guide protrusion 123a, that is, the distance from the rotation center of the rotating member 123 to the center of the guide protrusion 123a is L, and the moving path length of the rotating member 123 driving the opening and closing member is S, then S=2L-k.

[0285] 11 to 14 , it is defined that when the guide protrusion 123a slides to the first limit position in the guide groove 114b, the opening and closing member is in the open position; when the guide protrusion 123a slides to the second limit position in the guide groove 114b, the opening and closing member is in the closed position.

[0286] In one embodiment, the driver 122 is configured to stop operating immediately when the guide protrusion 123a is driven to move to the first limit position or the second limit position.

[0287] Alternatively, in one embodiment, the driver 122 is configured to continue operating when the guide protrusion 123a is moved to the first limit position or the second limit position, and the driver 122 stops operating after the guide protrusion 123a continues to slide to a certain stroke.

[0288] It should be noted that there are multiple ways to stop the control driver 122:

[0289] In one embodiment, the target rotation angle can be determined by calculating the rotation angle range of the driver 122. For example, based on the structural design parameters of the guide groove 114b, the guide protrusion 123a, etc., the required rotation angle for the guide protrusion 123a to move to the first limit position or the second limit position is calculated, and then the target rotation angle is used as the target rotation angle to control the driver 122 to stop operation.

[0290] Alternatively, in one embodiment, the rotation angle range of the rotating member 123 may be determined by limiting the rotation angle range of the rotating member 123. Specifically, the rotation angle range of the rotating member 123 may be set to be greater than 180° and less than 360°. When the rotation angle range is exceeded, the driver 122 is controlled to stop operating.

[0291] Alternatively, in one embodiment, an additional stop structure can be provided to mechanically stop the rotation of the rotating member 123 or the output shaft. Specifically, the stop structure can be provided, for example, within the guide groove 114b at a predetermined position corresponding to the sliding path of the guide protrusion 123a, or on the docking station 121 at a predetermined position corresponding to the rotation path of the rotating member 123.

[0292] Alternatively, in one embodiment, a sensor device can be provided to determine the active position of the guide protrusion 123a and / or the rotating member 123. Specifically, in conjunction with Figures 19 and 20, in one embodiment, the docking station 121 is provided with a position sensor 121b protruding from the side of the arc-shaped groove 121a, and the position sensor 121b is provided with a sensing portion 121c. The sensing portion 121c can be provided protruding from the side surface of the position sensor 121b facing the arc-shaped groove 121a, and the sensing portion 121c and the position sensor 121b can be integrally formed, or can be separately formed and then connected and fixed in a detachable or non-detachable manner. The sensing portion 121c can specifically be provided with a through groove 121d. The through groove 121d is adapted to be provided at the corresponding outer periphery of the rotating member 123. The through groove 121d can, to a certain extent, limit the rotation of the rotating member 123 along its rotation axis without affecting the rotation of the rotating member 123. The rotating member 123 is provided with a triggering portion corresponding to the sensing portion 121 c. When the triggering portion approaches the sensing portion 121 c, the position sensor 121 b is triggered to generate a sensing signal.

[0293] As shown in Figure 20, two of the aforementioned sensing parts 121c or position sensors 121b can be provided at intervals. Taking two sensing parts 121c as an example, the two sensing parts 121c correspond to the open position and closed position of the opening and closing member, respectively. The two sensing parts 121c are provided at intervals on the rotating periphery of the trigger portion of the rotating member 123. The driver 122 drives the rotating member 123 to rotate, and by switching the driver 122 between forward and reverse rotation, the trigger portion switches back and forth between the two sensing parts 121c.

[0294] It should be noted that when the driver 122 is configured to continue to operate for a certain distance after driving the guide protrusion 123a to the first or second limit position before stopping, in one embodiment, the guide protrusion 123a can be configured to disengage from the guide groove 114b after sliding for the distance, thereby completing the clutch connection between the rotating member 123 and the opening and closing member. There are various ways to disengage, such as gradually reducing the groove depth of the corresponding groove section of the guide groove 114b so that the guide protrusion 123a is gradually pushed out of the guide groove 114b; or the guide groove 114b can be configured to be open at both ends in the second direction so that the guide protrusion 123a can disengage from the guide groove 114b outward from the open ends.

[0295] Furthermore, based on the above description, and in conjunction with Figures 3 to 20 , the connecting base 113 is provided with a mounting slot 113a, within which a guide rod 115 is disposed, extending along a first horizontal direction. The opening and closing member may specifically include a cover plate 112 and a slider 114. The cover plate 112 covers the notch of the mounting slot 113a and is provided with a mounting hole 112a extending therethrough and communicating with the mounting slot 113a. The slider 114 is received within the mounting slot 113a and partially extends outward from the mounting hole 112a. The slider 114 is fixed relative to the cover plate 112. The portion of the slider 114 within the mounting slot 113a is provided with a guide hole 114a for slidably engaging with the guide rod 115. The portion of the slider 114 extending outside the mounting slot 113a is provided with the guide slot 114b or the guide protrusion 123a. The number of guide rods 115 provided may be one or multiple guide rods 115 extending side by side in the same direction. The guide holes 114 a are suitable for adaptively adjusting the number and positions of the guide rods 115 .

[0296] Of course, in one embodiment, the opening and closing member may specifically include a cover plate 112 and a slider 114, and the slider 114 is fixedly connected to one side of the cover plate 112 covering the mounting groove 113a and is not exposed on the outside of the cover plate 112. At this time, the above-mentioned guide groove 114b or the guide protrusion 123a may be provided on the side of the cover plate 112 facing away from the mounting groove 113a.

[0297] In addition, in one embodiment, the weighing device 130 is suspended in the inner cavity of the machine body and is roughly cantilevered. When the weighing module does not carry any material, the counterweight of the weighing part 131 of the weighing device 130 is set to be equivalent to the counterweight of the fixed part 132, or the counterweight of the weighing part 131 of the weighing device 130 is set to be smaller than the counterweight of the fixed part 132. That is, when the weighing module does not carry any material, the structural design is to set the weighing part 131 and the fixed part 132 of the weighing device 130 to be balanced with each other, or at least the weighing part 131 is smaller, so as to avoid the unbalanced force between the weighing part 131 and the fixed part 132 of the weighing device when not weighing, which may cause the cantilever weighing device to deflect, and easily reduce the weighing accuracy of the weighing device after long-term use.

[0298] It can be seen from the above embodiments that, for example, the docking seat 121 and the shell portion of the driver 122 of the present application constitute the above-mentioned main body; the rotation output shaft of the driver 122 and the rotating member 123 constitute the above-mentioned power output portion.

[0299] In view of the above, in one embodiment, the container body 111 is connected to one side of the opening and closing member in the first horizontal direction, and the feeding channel 111a extends in the vertical direction, and the opening and closing member is movably arranged along the first horizontal direction; the main body is arranged at intervals on one side of the open receiving container 110 in the vertical direction, and a connecting space is defined at the interval, and the power output part is passed through the connecting space; the blocking member 600 extends in the vertical direction and is arranged in the connecting space.

[0300] It will be appreciated that the connection space is defined by the gap between the receiving container 110 and the main body. The stopper 600 can be positioned anywhere within the connection space as needed. Furthermore, the main body can also define a movable space within which the power take-off unit can be positioned. This movable space is located within the connection space, and the space outside the movable space is the remaining space within which the stopper 600 can be positioned as needed. This arrangement not only facilitates the stopping function of the stopper 600 but also effectively prevents structural interference with the movement of the power take-off unit.

[0301] There are many schemes for constructing the connection space: for example, it is defined by the lower end surface of the connecting seat 113, the lower end surface of the container body 111 and at least one of the lower end surfaces of the opening and closing piece, and the upper end surface of the docking seat 121 and at least one of the upper end surfaces of the driver 122.

[0302] When the driving device 120 is basically located vertically below the connecting seat 113 and the container body 111 is located on one side of the driving device 120 in the first horizontal direction, the powder discharged outward from the lower end outlet of the container body 111 will mainly fly into the above-mentioned activity space along the first horizontal direction. Therefore, in one embodiment, the blocker 600 includes a first stop portion, which is arranged on one side of the connecting space along the first horizontal direction close to the container body 111, which helps to effectively block most of the flying powder in a targeted manner.

[0303] Furthermore, some of the powder discharged from the lower outlet of the container body 111 may fall into the aforementioned active space along the second horizontal direction. Therefore, in one embodiment, the stopper 600 includes a second stopper located on at least one side of the connecting space in the second horizontal direction. Specifically, if the connecting space has a first side and a second side in the second horizontal direction, then in one embodiment, two second stoppers may be provided, one on the first side and the other on the second side. Alternatively, in one embodiment, only one second stopper may be provided, which may be located on either the first or second side depending on actual needs. Actual needs may include, but are not limited to, the distance between the power take-off (PTO) and the first and second sides, respectively. If the PTO is closer to the first side, the second stopper may be located on the first side. Other considerations include airflow conditions between the first and second sides, such as airflow volume and direction. If airflow on the first side has a higher flow rate and flows toward the second side, the second stopper may be located on the first side.

[0304] In one embodiment, when the stopper 600 includes both a first stopper and a second stopper, the first stopper and the second stopper can be integrally formed, for example, by being formed from a single plate material that is partially bent and extended. Alternatively, the first stopper and the second stopper can be formed separately and then connected in a detachable or non-detachable manner.

[0305] In addition, it should be noted that when the weighing module is used in a beverage preparation device, the baffle 600 can be set on at least one of the housing, the grinding module, the brewing module and the weighing module at a corresponding position; or, the housing, the grinding assembly, the brewing module and / or the weighing module at least partially constitute the baffle 600.

[0306] Taking the stopper 600 (specifically, the first stopper) provided on the weighing module as an example, the receiving container 110 has a first surface facing the main body. The first surface can be the lower end surface of the container body 111, the lower end surface of the opening and closing member, and / or the lower end surface of the connecting seat 113. The driving device 120 has a second surface facing the receiving container 110. The second surface can be the upper end surface of the docking seat 121 and / or the upper end surface of the driver 122.

[0307] In one embodiment, the stopper 600 can be suspended in the connection space. That is, the upper end of the stopper 600 does not seal against the first surface, but instead forms a first gap. Similarly, the lower end of the stopper 600 does not seal against the second surface, but instead forms a second gap. The dimensions of the first and second gaps are set within a reasonable set spacing range to prevent excessive powder from passing through either the first or second gaps.

[0308] Alternatively, in one embodiment, the first gap can be set to be sufficiently small so that the upper end of the stopper 600 can be in movable contact with the first surface, and the second gap can be set to be sufficiently small so that the lower end of the stopper 600 can be in movable contact with the second surface. The manner of movable contact is not limited and can be sliding contact or rolling contact, etc.

[0309] Alternatively, in one embodiment, the upper end of the stopper 600 is connected to the first surface, while the lower end of the stopper 600 is separated from the second surface to form a second gap. In this case, the stopper 600 can be integrally formed with the first surface, so that a portion of the receiving container 110 directly constitutes the stopper 600. Alternatively, the stopper 600 can be separated from the first surface, with the upper end of the stopper 600 in relatively fixed, sealed contact with the first surface.

[0310] Alternatively, in one embodiment, the lower end of the stopper 600 is connected to the second surface, while the upper end of the stopper 600 is separated from the first surface to form a first gap. In this case, the stopper 600 can be integrally formed with the second surface, so that a portion of the drive device 120 directly constitutes the stopper 600. Alternatively, the stopper 600 can be separated from the second surface, with the lower end of the stopper 600 in relatively fixed, sealed contact with the second surface.

[0311] In one embodiment, at least one surface of the stopper 600 facing the container body 111 (i.e., the surface facing away from the connection space) may be smoothed. Smoothing methods may include, but are not limited to, substantially reducing the surface roughness of the side surface to achieve a smooth surface, or providing a layer of smooth material on the side surface. Examples of smooth materials include glass, ceramic, and some metals.

[0312] Alternatively, in one embodiment, at least one side surface of the baffle 600 facing the container body 111 (i.e., the side surface facing away from the linking space) can be subjected to a repulsive treatment. The repulsive treatment is to direct the falling powder away from the baffle 600. The repulsive treatment scheme may include, but is not limited to, providing a layer of electrostatic repulsive material on the side surface, providing air holes on the side surface and causing the air holes to blow outward, etc. Examples of electrostatic repulsive materials include antistatic organic glass plates (antistatic acrylic plates), antistatic PVC plates (antistatic polyvinyl chloride plates), antistatic PC plates (antistatic polycarbonate plates), antistatic PET plates (polyethylene terephthalate plates), and antistatic nylon plates (MC501CDR6).

[0313] Alternatively, in one embodiment, at least one surface of the baffle 600 facing the container body 111 (i.e., the surface facing away from the connection space) can be subjected to a suction process. This suction process involves attracting falling powder to a designated area of ​​the baffle 600. This suction process can include, but is not limited to, providing air holes on this side surface that direct suction inward, or providing a layer of electrostatic adsorption material on this side surface. The designated area can further include a structure for collecting powder, such as a collection chamber or trough.

[0314] In one embodiment, the blocking member 600 may be tilted relative to the vertical direction to form an inclined guide surface to guide the powder away from the driving device 120 .

[0315] In view of the above embodiments, in a further solution, the present application also provides a beverage preparation device. The beverage preparation device includes a housing, a grinding module, a brewing module and a weighing module. The grinding module is arranged in the housing and is used to grind the raw materials into powder; the brewing module is arranged in the housing and is used to receive the raw material powder and brew it; the weighing module is arranged in the housing and is connected between the grinding module and the brewing module. The weighing module includes a receiving container 110 and a driving device 120. The receiving container 110 includes a container body 111 and an opening and closing member. The driving device 120 drives the opening and closing member to movably open and close the container body 111. When the weighing module is installed in the housing, at least one of the housing, the grinding module and the brewing module separates the driving device 120 of the weighing module from the discharge port of the container body 111.

[0316] In this way, the housing, the grinding module and / or the brewing module that separate the driving device 120 from the discharge port of the container body 111 can prevent the powder discharged outward through the discharge port of the container body 111 from flying onto the driving device 120.

[0317] Based on this, in a further solution, the weighing module can be the weighing module described above, that is, including a stopper 600. In this case, in one embodiment, the housing, the grinding module, and / or the brewing module that separates the driving device 120 from the discharge port of the container body 111 are independently provided with the stopper 600. In other words, the stopper 600 is a structure that exists independently of the housing, the grinding module, and / or the brewing module, but the stopper 600 and the housing, the grinding module, and / or the brewing module that separates the driving device 120 from the discharge port of the container body 111 can each prevent the powder from flying onto the driving device 120, which is equivalent to forming a two-stage stopper.

[0318] Of course, in another embodiment, the housing, the grinding module, and / or the brewing module that separates the driving device 120 from the discharge port of the container body 111 at least partially constitutes the blocking member 600. That is, the blocking member 600 and at least partially the housing, the grinding module, and / or the brewing module that separates the driving device 120 from the discharge port of the container body 111 are of the same structure.

[0319] It should be emphasized that the beverage preparation equipment in the present application can be a bean grinder for grinding coffee beans, the weighing module can be arranged in the coffee bean grinder, the grinder is provided with a grinding module, the weighing module and the setting are matched with the grinding module of the grinder, the installation and control method of the weighing module in the grinder are the same as above, and the powder material weighed by the weighing module can be received by the powder bowl and then brewed manually.

[0320] Fourth application example:

[0321] Referring to Figures 1, 2-8, and 10-16, this application provides a beverage preparation device comprising a housing and a weighing module. The housing comprises at least a housing defining an inner cavity, a grinding module disposed within the inner cavity, and a brewing module, the housing being provided with a mating structure. Furthermore, to enable intelligent and automatic operation of the beverage preparation device, the housing may further include a control device housed within the inner cavity of the housing and / or a display module at least partially exposed on the outer wall of the housing.

[0322] This design does not limit the specific type of beverage preparation device; it can be any device or product that can extract and brew materials to ultimately produce a beverage. Specifically, the beverage preparation device can be, but is not limited to, a coffee machine, a soymilk maker, a bean grinder, a food processor, etc. Correspondingly, the materials involved in this application can be beans such as coffee beans and soybeans. For ease of understanding, the following embodiments are described using a coffee machine as an example of a beverage preparation device, where the materials include coffee beans that have not been ground by a grinding module, as well as coffee powder obtained after being ground by a grinding module.

[0323] The grinding module may include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder defines a grinding chamber; the grinding mechanism includes, for example, a movable cutting tool and a first drive assembly that actuates the cutting tool. The cutting tool can be designed with a desired shape and suitable motion to facilitate puncturing, grinding, stirring, and other crushing operations on granular materials such as coffee beans. Examples of these tools include bayonets and blade discs. The outlet of the grinding module refers to the outlet of the grinding cylinder.

[0324] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee beverage. The brewing mechanism is mainly configured as a pressing mechanism, a heating mechanism and / or a water supply component according to different brewing requirements. In addition, the brewing mechanism can also be configured as, but is not limited to, a refrigeration mechanism and / or a milk supply component, etc. according to actual needs, to obtain different types of coffee beverages. The inlet end of the brewing module refers to the inlet end of the brewing cylinder.

[0325] In view of the above, the following is specifically described by taking as an example a beverage preparation device in which the body includes a grinding module and a brewing module, and the weighing module is arranged between the outlet end of the grinding module and the inlet end of the brewing module:

[0326] In conjunction with Figures 1 to 3 , the present application further provides a weighing module, which is used in the aforementioned beverage preparation device and is specifically housed within the inner cavity of the housing. The weighing module can be disposed between the outlet of the grinding module and the inlet of the brewing module in the housing. The inlet of the weighing module is connectable and disconnectable to the outlet of the grinding module, and the outlet of the weighing module is connectable and disconnectable to the inlet of the brewing module. When the inlet of the weighing module is connected to the outlet of the grinding module and the outlet of the weighing module is disconnected from the inlet of the brewing module, the weighing module can receive and store coffee powder discharged from the outlet of the grinding module, while simultaneously or with a delay performing a weighing function, thereby operating in a weighing mode. When the inlet of the weighing module is connected to the outlet of the grinding module and the outlet of the weighing module is connected to the inlet of the brewing module, the weighing module primarily serves as a powder transition device and does not perform a weighing function, thereby operating in a non-weighing mode.

[0327] When the weighing module is used in a beverage preparation device, it is placed in the machine body as a modular component. The plug-in structure of the weighing module and the matching structure of the machine body can be quickly disassembled and assembled. When the weighing module is installed in the housing and located between the grinding module and the brewing module, the current position of the weighing module constitutes the preset installation position:

[0328] In one embodiment, when the weighing module is removed from the machine body, the pre-set installation position becomes vacant, creating a gap between the grinding module and the brewing module. Optionally, a plug-in structure can also be provided on the grinding module and / or the brewing module. Based on this plug-in structure, the grinding module and / or the brewing module can be plugged into a mating structure on the machine body to replace the pre-set installation position, thereby placing the brewing module and the grinding module as close together as possible to prevent powder from scattering during transfer.

[0329] Alternatively, in one embodiment, a detachable or integral, deformable connecting structure can be provided between the grinding module and / or the brewing module. When the weighing module is installed in the housing, the connecting structure compresses and deforms; conversely, when the weighing module is removed from the housing, the connecting structure extends and deforms, connecting the outlet of the grinding module with the inlet of the brewing module, thereby preventing a gap from forming between the grinding module and the brewing module. The connecting structure can be a soft rubber channel, etc., and its specific form is not limited.

[0330] Based on this, further, in one embodiment, the beverage preparation device can also identify whether the weighing module is installed in the casing through its own preset or externally connected control device, combined with one or several sensor devices, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0331] In view of the above, it can be seen that the beverage preparation device and / or the weighing module are pre-set with optional weighing mode and non-weighing mode. In actual application, the beverage preparation device can adjust whether the whole machine is currently in weighing mode or non-weighing mode by manual setting based on, for example, preset buttons. Among them, when the whole machine is in non-weighing mode, the weighing component can be in an uninstalled state when it is removed from the inside of the casing, or it can be in an installed state installed in the casing. When the weighing module is in an installed state installed in the casing, the weighing module can be used as a transfer mechanism for conveying powder from the grinding module to the brewing module as described above. The weighing module is set to a normally open form, which is equivalent to a connecting pipeline. When the powder is conveyed from the grinding module to the brewing module, the powder passes through the weighing module freely and unobstructed.

[0332] In the present design, the weighing module includes a receiving container 110, a driving device 120, a weighing device 130 and a scraper 710. The receiving container 110 includes a container body 111 and a cover plate 112. The container body 111 is provided with a material delivery channel 111a. The cover plate 112 is movably installed on the container body 111 to have an open position for conducting the material delivery channel 111a and a closed position for closing the material delivery channel 111a. When in the closed position, the cover plate 112 has a bearing surface facing the material delivery channel 111a. The driving device 120 is driven and connected to the cover plate 112. The weighing device 130 includes a weighing portion 131 directly or indirectly connected to the receiving container 110. The scraper 710 protrudes toward the bearing surface and is arranged between the open position and the closed position. During the movement of the cover plate 112 from the closed position to the open position, the scraper 710 abuts against the bearing surface.

[0333] In the technical solution provided in the present application, when the driving device 120 drives the cover 112 to move to the closed position, the container body 111 can receive the powder to be tested, for example, discharged through the grinding module, and the weighing device 130 can simultaneously or delayedly measure the weight of the powder to be tested received by the container body 111; when the weight measurement operation is completed, the driving device 120 drives the cover 112 to move to the open position, and the bearing surface will carry a part of the powder and drive it to move toward the open position. During this process, the scraper 710 is in contact with the bearing surface, and can scrape the powder taken away by the bearing surface toward the brewing module, ensuring that the powder weighed in the container body 111 is relatively completely transferred to the brewing module, thereby helping to improve the brewing quality of the powder by the brewing module.

[0334] It should be noted that when the weighing module is used in a beverage preparation device, it can be assembled into the body in any suitable posture according to actual needs. For ease of understanding, in the following embodiments, the beverage preparation device as a whole and its components have approximately perpendicular horizontal and vertical directions. The vertical direction is also approximately the direction of gravity. The horizontal direction is any suitable direction on the horizontal plane, which can specifically be a first horizontal direction and a second horizontal direction arranged in a cross pattern. The angle between the first horizontal direction and the second horizontal direction can be set to approximately 90°.

[0335] In this design, the container body 111 is generally cylindrical, with the space within the cylinder directly defining a feed channel 111a. The feed channel 111a can extend in a direction as needed, for example, vertically or in a direction inclined relative to the vertical. Of course, the feed channel 111a can be configured as a straight channel structure or, depending on actual needs, as a channel structure that is at least partially curved.

[0336] The cover plate 112 can be positioned anywhere within the feed channel 111a, for example, at the inlet end of the feed channel 111a, at the outlet end of the feed channel 111a, or anywhere between the inlet and outlet ends of the feed channel 111a. For example, as shown in Figures 4 and 5 , the cover plate 112 is positioned at the outlet end of the feed channel 111a and is externally positioned to the container body 111. The cover plate 112 is generally plate-shaped. The shape and dimensions of the portion of the cover plate 112 that covers the outlet end of the feed channel 111a can be adapted to the outlet end of the feed channel 111a.

[0337] There is no limitation on the movement of the cover 112 relative to the container body 111:

[0338] In one embodiment, the cover plate 112 is capable of flipping relative to the container body 111. Specifically, one end of the cover plate 112 is rotatably connected to an edge of the outlet end of the material delivery channel 111a, and the other end of the cover plate 112 is capable of flipping to a closed position at the other edge of the outlet end of the material delivery channel 111a, and flipping to an open position at the other edge of the outlet end of the material delivery channel 111a, facing away from the outlet end of the material delivery channel 111a.

[0339] Alternatively, in the embodiment shown in Figures 4 and 5, the cover plate 112 can be translated relative to the container body 111. Specifically, the cover plate 112 is offset to one side of the outlet end of the material delivery channel 111a and can be translated to a closed position toward the other side of the outlet end of the material delivery channel 111a, and can be translated to an open position away from the other side of the outlet end of the material delivery channel 111a.

[0340] The configuration of the drive device 120 is related to the movement of the cover 112. The drive device 120 includes at least a drive assembly, which is operatively connected to the cover 112 to drive the cover 112 back and forth between a closed position and an open position. The fixing portion 132 can be connected to a portion of the drive assembly that is not connected to the cover 112 and is relatively fixed, such as the housing structure.

[0341] Alternatively, please refer to Figures 6 to 8 for details. In one embodiment, the drive device 120 includes a docking seat 121 and a drive assembly. The docking seat 121 is connected and fixed to a fixing portion 132. Specifically, in one application, the fixing portion 132 is disposed at one end of the top of the docking seat 121. The drive assembly is disposed on the docking seat 121 and is detachably connected to the cover plate 112. When the drive assembly is connected and drives the cover plate 112 to move to the open position, it can continue to maintain connection with the cover plate 112. After the drive assembly is connected and drives the cover plate 112 to move to the closed position, the drive assembly and the cover plate 112 are disconnected and separated from each other, entering a non-contact state. A receiving cavity can be formed within the docking seat 121. The docking seat 121 can be configured to be enclosed, with the drive assembly at least partially sealed and accommodated within the receiving cavity. The provision of the docking seat 121 can provide a connection space for the fixing portion 132 that is independent of the drive assembly, while also providing a stable, sealed accommodation space for the drive assembly.

[0342] The weighing device 130 is roughly cantilevered and includes a fixed portion 132 and a weighing portion 131. The fixed portion 132 is connected to a fixed support within the beverage preparation device. The fixed support may be, but is not limited to, one or more of a housing, a grinding module, and a brewing module. The weighing portion 131 is fixedly connected to the receiving container 110.

[0343] Since the weighing device 130 is roughly in the shape of a cantilever extending along the first horizontal direction, its weighing part 131 and fixing part 132 are respectively arranged at the two ends of the first horizontal direction. Therefore, in actual application, please refer to Figures 1 and 16, the weighing part 131 is connected to the receiving container 110, and at least the part of the receiving container 110 connected to the weighing part 131 can be suspended vertically below the weighing part 131, or it can be supported vertically above the weighing part 131. Similarly, the fixing part 132 is connected to the driving device 120, and the part of the driving device 120 that can be connected to the fixing part 132 can be connected vertically below the fixing part 132, or it can be connected vertically above the fixing part 133.

[0344] When at least the portion of the receiving container 110 connected to the weighing unit 131 is supported vertically above the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing pressure changes. When at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing tension changes.

[0345] The portion where the receiving container 110 is connected to at least the weighing part 131, and the portion where the driving device 120 / fixed carrier is connected to at least the fixing part 132, can be arranged on both sides of the weighing device 130 in the vertical direction, or can be located on the same side of the weighing device 130 in the vertical direction.

[0346] However, for ease of understanding, the following embodiments are described as follows, assuming that at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, and at least the portion of the driving device 120 connected to the fixing unit 132 is connected vertically below the fixing unit 132. Specifically, as shown in FIG8 , the connecting base 113 is suspended below the weighing unit 131 and is fixedly connected to the lower end of the weighing unit 131.

[0347] In the above embodiment, by arranging the drive assembly at the docking seat 121 and connecting the fixing portion 132 to the docking seat 121, the drive assembly directly applies a downward force to the fixing portion 132, and only bears the direct downward force exerted by the container body 111 and the powder contained in the container body 111 on the weighing portion 131. Compared to the conventional solution in which the drive assembly and the container body 111 are integrally arranged in the weighing portion 131, the weighing portion 131 in this design does not bear the weight of the drive assembly. In this way, the heavy drive assembly can be effectively prevented from causing a force burden on the weighing portion 131, thereby ensuring that the weighing results of the weighing portion 131 in this design are more sensitive and accurate. It also effectively prevents the vibration generated by the drive assembly during operation from causing measurement deviations in the weighing portion 131, thereby ensuring that the weighing process of the weighing portion 131 in this design is more stable and effective.

[0348] Furthermore, in one embodiment, the receiving container 110 further includes a connecting seat 113 extending below the weighing device 130 and connected to the weighing device 130. The container body 111 and the weighing portion 131 are connected and fixed to the connecting seat 113. The cover 112 is movably mounted on the connecting seat 113 in a first horizontal direction close to and away from the container body 111. The projection of the weighing device 130 on the horizontal plane is completely located within the projection plane of the connecting seat 113 on the horizontal plane. The driving assembly includes a driver 122 and a rotating member 123. The driver 122 is a rotating member 123. 122 and the fixing portion 132 are both connected and fixed to the docking seat 121, the driver 122 is drivingly connected to the rotating member 123, and one of the connection points between the rotating member 123 and the cover plate 112 is provided with a guide groove 114b extending along a second horizontal direction intersecting the first horizontal direction, and the other is provided with a guide protrusion 123a. During the rotation of the rotating member 123, the guide protrusion 123a has a first stroke section in which it contacts the guide groove 114b and slides along the guide groove 114b, and a second stroke section that is out of contact with the guide groove 114b.

[0349] The driver 122 performs a rotational output and can be a motor or a combination of a motor and a transmission assembly. The transmission assembly can be, for example, a gear set, a worm gear mechanism, or the like. The rotating member 123 is connected to the rotational output shaft of the driver 122 so that, under the rotational drive of the rotational output shaft of the driver 122, the rotating member 123 can be driven by the driver 122 to rotate in the same direction, ultimately driving the guide protrusion 123a to slide against and contact the guide groove 114b. Since the guide groove 114b extends along the second horizontal direction, the rotational motion of the rotating member 123 can be converted into a translational motion that pushes the guide groove 114b along the first horizontal direction and the movement of the protrusion of the rotating member 123 within the guide groove 114b toward the second horizontal direction, ultimately achieving the purpose of driving the cover plate 112 to perform translational movement along the first horizontal direction. The second horizontal direction in which the guide groove 114b extends is perpendicular to the first horizontal direction of the translational motion of the guide groove 114b. In the above description, when the guide protrusion 123a performs the first stroke segment, the driver 122, the rotating member 123 and the cover plate 112 are in a mutually contacted and connected state, and the driving force of the driver 122 can eventually be transmitted to the cover plate 112, thereby realizing the mutual switching of the cover plate 112 between the open position and the closed position; when the guide protrusion 123a performs the second stroke segment, the driver 122, the rotating member 123 and the cover plate 112 are in a disconnected state, and the driving force of the driver 122 cannot be transmitted to the cover plate 112, and the cover plate 112 is locked in the current position (specifically set to the closed position). At this time, the driving device 120 and the receiving container 110 basically remain in a separated state. The driving device 120 independently applies force to the fixed part 132 of the weighing device 130, and the receiving container 110 independently applies force to the weighing part 131 of the weighing device 130. This helps to avoid the gravity of the driving device 120 from affecting the weight measurement of the material received by the receiving container 110, and therefore helps to improve the weighing accuracy and optimize the weighing effect.

[0350] It should be noted that when the guide protrusion 123a is in the first travel segment, the guide protrusion 123a is in sliding engagement with at least the sidewall of the guide groove 114b. Optionally, the top of the guide protrusion 123a can be in sliding engagement with the bottom wall of the guide groove 114b, thereby ensuring a smoother sliding connection between the guide protrusion 123a and the guide groove 114b. Alternatively, the top of the guide protrusion 123a can be spaced apart from the bottom wall of the guide groove 114b, thereby ensuring that the connecting base 113 remains suspended above the guide protrusion 123a and the docking base 121. In this manner, apart from the weighing portion 131 in direct contact with the container body 111 and the fixing portion 132 in direct contact with the docking base 121, no other components come into contact with the weighing device 130. This minimizes any other contact during weighing by the weighing device 130, thereby ensuring accurate weighing.

[0351] In a preferred embodiment, the guide protrusion 123a may include a boss and a ring sleeved on the outer circumference of the boss, wherein the ring can be sleeved on the boss and rotate around the boss, and the ring contacts and drives the cover plate 112 to move in the guide groove 114b. The friction force formed by the contact of the ring driving the guide groove 114b is converted into rolling friction force, thereby reducing the friction generated and preventing wear and friction noise caused by long-term contact friction.

[0352] Further, please refer to Figures 6 to 8. In one embodiment, the outer top wall of the docking seat 121 is provided with a circular limiting hole 121f that passes through the inner wall and an arc-shaped groove 121a that is provided on the outer periphery of the limiting hole 121f. The arc length of the arc-shaped groove 121a is not less than the arc length corresponding to the guide protrusion 123a when performing the first stroke segment. The rotating member 123 includes a rotating arm 123c and a rib 123c that protrudes downward from the bottom end of the rotating arm 123c to extend into the arc-shaped groove 121a. 3d, a rotating boss 123e protrudes from one radial end of the rotating arm 123c, facing toward the docking seat 121. The rotating boss 123e is rotatably connected to the limiting hole 121f of the docking seat 121. A guide protrusion 123a protrudes from the other radial end of the rotating arm 123c, facing away from the docking seat 121. A rib 123d slides along the side walls of the arcuate groove 121a. The driver 122 is housed within the docking seat 121, and the drive shaft extends upward and outward from the through-limiting hole 121f. To enhance the structural strength of the rotating arm 123c, in one embodiment, the rotating member 123 may further include fan-shaped plates 123b extending from both sides of the rotating arm 123c.

[0353] In one embodiment of the present application, the rotating boss 123e is mounted on the drive shaft of the driver 122 and is located above the limiting hole 121f. The outer diameter of the rotating boss 123e is larger than the aperture of the limiting hole 121f, so that the rotating boss 123e can cover the area above the limiting hole 121f. In another embodiment, the rotating boss 123e extends into the limiting hole 121f, wherein the outer diameter of the rotating boss 123e substantially matches the aperture of the limiting hole 121f, so that the rotating boss 123e fills the entire limiting hole 121f.

[0354] Specifically, the arcuate groove 121a can be arranged along the entire circumference of the rotation axis of the rotating member 123, so that the rib 123d can slide along the entire circumference of the side groove wall of the arcuate groove 121a, thereby achieving unidirectional and full-circumferential rotation of the rotating member 123. Alternatively, the arcuate groove 121a can be arranged partially along the circumference of the rotation axis of the rotating member 123, so that when the rib 123d slides along the side groove wall of the arcuate groove 121a, the rotating member 123 can achieve unidirectional rotation of a limited arc length.

[0355] The plate 123b, rotating arm 123c, rib 123d, and guide protrusion 123a of the rotating member 123 can be integrally formed, or they can be formed separately and then removably or non-removably connected and fixed. The provision of the rotating arm 123c and rib 123d helps to reduce material consumption of the rotating member 123 and prevents excessive sliding connection between the rotating member 123 and the guide groove 114b and the arcuate groove 121a, which would increase sliding losses.

[0356] It should be noted that, in order to allow the guide protrusion 123a to extend into and out of the guide groove 114b, in one embodiment, the outer peripheral surface of the guide protrusion 123a and / or the corresponding side groove wall of the guide groove 114b can be configured as an inclined straight surface or an arcuate surface to provide smooth guidance. Alternatively, in one embodiment, the rotating member 123 can be telescopically mounted on the docking seat 121 relative to its own rotational axis, and the arcuate groove 121a can be configured with a gradually increasing depth in the portion corresponding to the second stroke segment.

[0357] As can be seen from the above, the rotation of the rotating member 123 simultaneously drives the guide protrusion 123a to slide along the guide groove 114b, and simultaneously drives the rib 123d to slide along the arcuate groove 121a. Therefore, in order to limit the rotation angle range of the rotating member 123, the sliding strokes of the rotating member 123 itself, the guide protrusion 123a and the guide groove 114b, and the sliding strokes of the rib 123d and the arcuate groove 121a can be specifically configured.

[0358] In view of the above, referring to FIG10 , when the cover plate 112 translates along the first horizontal direction, the guide slot 114b extends substantially along a second horizontal direction perpendicular to the first horizontal direction. In this case, the guide slot 114b includes at least a first side slot wall and a second side slot wall disposed opposite each other in the first horizontal direction, both of which extend along the second horizontal direction. If the distance between the first side slot wall and the second side slot wall, i.e., the slot width of the guide slot 114b, is k, and the length of the guide protrusion 123a of the rotating member 123 along the first horizontal direction, i.e., the radius of the guide protrusion 123a when the guide protrusion 123a is cylindrical, is r, then k is greater than twice r. This means that when the guide protrusion 123a is located between the first side slot wall and the second side slot wall, it can only abut against the first side slot wall or the second side slot wall. When the guide protrusion 123a abuts against the first side slot wall or the second side slot wall, the gap between the guide protrusion 123a and the other slot wall is t. This helps to avoid excessive friction interference between the guide protrusion 123a and the guide groove 114b, ensuring that the guide protrusion 123a can slide along the guide groove 114b.

[0359] If the rotation radius of the guide protrusion 123a, that is, the distance from the rotation center of the rotating member 123 to the center of the guide protrusion 123a is L, and the moving path length of the cover plate 112 driven by the rotating member 123 is S, then S=2L-k.

[0360] 11 to 14 , if it is defined that when the guide protrusion 123a slides to the first limit position in the guide groove 114b, the cover 112 is in the open position; when the guide protrusion 123a slides to the second limit position in the guide groove 114b, the cover 112 is in the closed position.

[0361] In one embodiment, the driver 122 is configured to stop operating immediately when the guide protrusion 123a is driven to move to the first limit position or the second limit position.

[0362] Alternatively, in one embodiment, the driver 122 is configured to continue operating when the guide protrusion 123a is moved to the first limit position or the second limit position, and the driver 122 stops operating after the guide protrusion 123a continues to slide to a certain stroke.

[0363] It should be noted that there are multiple ways to stop the control driver 122:

[0364] In one embodiment, the target rotation angle can be determined by calculating the rotation angle range of the driver 122. For example, based on the structural design parameters of the guide groove 114b, the guide protrusion 123a, etc., the required rotation angle for the guide protrusion 123a to move to the first limit position or the second limit position is calculated, and then the target rotation angle is used as the target rotation angle to control the driver 122 to stop operation.

[0365] Alternatively, in one embodiment, the rotation angle range of the rotating member 123 may be determined by limiting the rotation angle range of the rotating member 123. Specifically, the rotation angle range of the rotating member 123 may be set to be greater than 180° and less than 360°. When the rotation angle range is exceeded, the driver 122 is controlled to stop operating.

[0366] Alternatively, in one embodiment, an additional stop structure can be provided to mechanically stop the rotation of the rotating member 123 or the output shaft. Specifically, the stop structure can be provided, for example, within the guide groove 114b at a predetermined position corresponding to the sliding path of the guide protrusion 123a, or on the docking station 121 at a predetermined position corresponding to the rotation path of the rotating member 123.

[0367] Alternatively, in one embodiment, a sensor device can be provided to determine the active position of the guide protrusion 123a and / or the rotating member 123. Specifically, in conjunction with Figures 6 and 8, in one embodiment, the docking station 121 is provided with a position sensor 121b protruding from the side of the arc-shaped groove 121a, and the position sensor 121b is provided with a sensing portion 121c. The sensing portion 121c can be provided protrudingly on the side surface of the position sensor 121b facing the arc-shaped groove 121a, and the sensing portion 121c and the position sensor 121b can be integrally formed, or can be separately formed and then connected and fixed in a detachable or non-detachable manner. The sensing portion 121c can specifically be provided with a through groove 121d. The through groove 121d is adapted to be provided at the corresponding outer periphery of the rotating member 123. The through groove 121d can, to a certain extent, limit the rotation of the rotating member 123 along its rotation axis without affecting the rotation of the rotating member 123. The rotating member 123 is provided with a triggering portion corresponding to the sensing portion 121 c. When the triggering portion approaches the sensing portion 121 c, the position sensor 121 b is triggered to generate a sensing signal.

[0368] As shown in Figure 15 , two of the aforementioned sensing portions 121c or position sensors 121b can be provided at intervals. Taking two sensing portions 121c as an example, the two sensing portions 121c correspond to the open and closed positions of the cover 112, respectively. The two sensing portions 121c are spaced apart on the rotating periphery of the trigger portion of the rotating member 123. The driver 122 drives the rotating member 123 to rotate, and by switching the driver 122 between forward and reverse rotation, the trigger portion switches back and forth between the two sensing portions 121c.

[0369] It should be noted that when the driver 122 is configured to continue to operate for a certain distance after driving the guide protrusion 123a to the first or second limit position before stopping, in one embodiment, the guide protrusion 123a can be configured to disengage from the guide groove 114b after sliding for the distance, thereby completing the clutch connection between the rotating member 123 and the cover plate 112. There are various ways to disengage the guide protrusion 123a, such as gradually reducing the groove depth of the corresponding groove section of the guide groove 114b so that the guide protrusion 123a is gradually pushed out of the guide groove 114b; or the guide groove 114b can be configured to be open at both ends in the second direction so that the guide protrusion 123a can disengage from the guide groove 114b outward from the open ends.

[0370] In addition, based on the above, please refer to Figures 4 to 5. In one embodiment, the connecting seat 113 is provided with a mounting groove 113a, the cover plate 112 covers the notch of the mounting groove 113a, and is penetrated by a mounting hole 112a connected to the mounting groove 113a, and the driving assembly further includes a slider 114 and a guide rod 115, wherein the slider 114 is accommodated in the mounting groove 113a and is arranged to be movably translated along the above-mentioned first horizontal direction, a part of the slider 114 extends from the mounting hole 112a to the outside of the mounting groove 113a, the slider 114 is relatively fixed to the cover plate 112, wherein the portion of the slider 114 accommodated in the mounting groove 113a is provided with a guide hole 114a, and the portion of the slider 114 extending out of the mounting groove 113a is provided with a guide groove 114b or a guide protrusion 123a; the guide rod 115 extends along the first horizontal direction and is arranged in the mounting groove 113a, and is slidably connected and cooperated with the guide hole 114a. The number of guide rods 115 can be one or a plurality of guide rods 115 extending side by side in the same direction. The guide holes 114a are suitable for adaptively adjusting the number and position of the guide rods 115.

[0371] In addition, in one embodiment, the weighing device 130 is suspended in the inner cavity of the machine body and is roughly cantilevered. When the weighing module does not carry any material, the counterweight of the weighing part 131 of the weighing device 130 is set to be equivalent to the counterweight of the fixed part 132, or the counterweight of the weighing part 131 of the weighing device 130 is set to be smaller than the counterweight of the fixed part 132. That is, when the weighing module does not carry any material, the structural design is to set the weighing part 131 and the fixed part 132 of the weighing device 130 to be balanced with each other, or at least the weighing part 131 is smaller, so as to avoid the unbalanced force between the weighing part 131 and the fixed part 132 of the weighing device when not weighing, which may cause the cantilever weighing device to deflect, and easily reduce the weighing accuracy of the weighing device after long-term use.

[0372] In view of the above-mentioned embodiment of the weighing module, the feed channel 111a has a discharge channel opening. The area of ​​the bearing surface is set to be no less than the cross-sectional area of ​​the discharge channel opening. The overall size of the cover 112 can be set to be relatively small according to actual needs, for example, just equivalent to the cross-sectional area of ​​the discharge channel opening, so that the entire upward surface of the cover 112 is the bearing surface. Or the overall size of the cover 112 can be set to be relatively large according to actual needs, so that the upward surface of the cover 112 partially constitutes the bearing surface. Therefore, for ease of understanding, the closed position of the cover 112 generally refers to the position of the bearing surface when it moves to just cover the discharge channel opening; the open position of the cover 112 generally refers to the position of the bearing surface when it moves to be completely offset from the discharge channel opening.

[0373] Based on this, in one embodiment, the scraper 710 is arranged closer to the closed position than the open position. That is, the scraper 710 is sufficiently close to the closed position of the cover 112. Specifically, it can be expressed as follows: the scraper 710 is arranged closer to the container body 111. In view of the above, it can be seen that the closed position of the cover 112, that is, the position where the bearing surface just covers the discharge channel opening, is equivalent to the position of the discharge channel opening. Generally, the discharge channel opening is arranged opposite to the inlet end of the brewing module, so that when the weighing device 130 completes the weight measurement of the bearing container and the powder carried therein, the cover 112 opens the feed channel 111a, and the powder will just enter the inlet end of the brewing module. Therefore, by bringing the scraper 710 sufficiently close to the closed position of the cover plate 112, when the cover plate 112 and the scraper 710 produce relative displacement, the scraper 710 can scrape off part of the powder carried on the supporting surface, and the scraped powder can more easily enter the inlet end of the brewing module and be further away from the connection between the drive device 120 and the cover plate 112, thereby helping to fully recover the powder scraped by the scraper 710 and effectively prevent the scraped powder from entering the connection between the drive device 120 and the cover plate 112, thereby interfering with the power transmission between the drive device 120 and the cover plate 112.

[0374] Furthermore, in one embodiment, the cover plate 112 reciprocates between an open position and a closed position along a first horizontal direction, and in a second horizontal direction, the size of the scraper 710 is not less than the size of the discharge channel opening. It is understood that the maximum cross-sectional area of ​​the powder carried on the bearing surface is generally not greater than the cross-sectional area of ​​the discharge channel opening. Therefore, in the second horizontal direction, the maximum size of the powder carried on the bearing surface is generally not greater than the maximum size of the discharge channel opening. By setting the size of the scraper 710 in the second horizontal direction to be larger, when the scraper 710 and the cover plate 112 are relatively displaced, the scraper 710 can fully act on all areas of the powder carried on the bearing surface, thereby helping to scrape off the powder carried on the bearing surface at one time.

[0375] It is understood that the scraper 710 can be provided on at least one of the housing, the grinding module, the brewing module, and the weighing module. Furthermore, the scraper 710 and the housing, the grinding module, the brewing module, and / or the weighing module can be integrally formed or separately provided with a detachable or non-detachable connection.

[0376] Take the scraper 710 provided in the weighing module as an example:

[0377] In one embodiment, the receiving container 110 further includes a connecting seat 113, which extends and protrudes from the side wall of the container body 111 toward the weighing part 131 and is fixedly connected to the weighing part 131. The container body 111 and / or the connecting seat 113 are provided with a mounting surface, and the scraper 710 protrudes from the mounting surface toward the bearing surface. During the movement of the cover 112 from the closed position to the open position, at least in a certain stroke section, the bearing surface will move to face the mounting surface. By arranging the scraper 710 at the mounting surface, it is possible to ensure the stable installation of the scraper 710, enhance the scraping strength of the scraper 710, and make the structure of the scraper 710 as simple as possible and use less materials.

[0378] When a mounting surface is provided as described above, and the scraper 710 protrudes from the mounting surface toward the bearing surface, the distance between the mounting surface and the bearing surface is set to H1, and the protruding dimension of the scraper 710 is set to H2. Based on this:

[0379] In one embodiment, when the scraper 710 is made of a rigid material, H2 is set to be equivalent to H1. This equivalent means that the dimensions of H2 and H1 can be exactly the same, or within a preset deviation range. A rigid material, i.e., a material with relatively high hardness, such that when the scraper 710 and the cover plate 112 come into sliding contact, the scraper 710 is essentially unaffected by force and deformation. Examples include hard polymer materials or metal materials. The scraper 710 is not easily deformed by the interaction force, thereby ensuring that the scraper 710 has sufficient scraping strength against the load-bearing surface, thereby optimizing the scraping effect on the load-bearing surface.

[0380] Alternatively, in one embodiment, when the scraper 710 is made of a flexible material, H2 is set to be no less than H1. This allows the length of the scraper 710 to be slightly greater than the distance between the mounting surface and the load-bearing surface. When the scraper 710 and the cover plate 112 come into sliding contact, the portion of the scraper 710 near the load-bearing surface bends and deforms, which not only helps to increase the contact force between the scraper 710 and the load-bearing surface, but also helps to expand the scraping area between the scraper 710 and the load-bearing surface, thereby optimizing the scraping effect on the load-bearing surface.

[0381] In addition, the present application further provides a weighing module, which includes the receiving container, the driving device, and the weighing device as described above. In addition, the weighing module also includes a flexible structure 720.

[0382] In a further embodiment, the container body 111 has a discharge surface, which is provided with a discharge channel opening connected to the feed channel 111a. It should be noted that the discharge surface can at least partially constitute the above-mentioned mounting surface; or the discharge surface and the mounting surface can be provided independently of each other.

[0383] The discharge surface and / or the supporting surface are provided with a flexible structure 720, so that when the cover plate 112 is moved to the closed position, the discharge surface and the supporting surface flexibly abut at the flexible structure 720. The flexible structure 720 can be a flexible material layer disposed on the discharge surface and / or the supporting surface; alternatively, the flexible structure 720 can be a flexible protrusion protruding from the discharge surface and / or the supporting surface. The provision of the flexible structure 720 facilitates partial or full flexible abutment between the supporting surface and the discharge surface when in the closed position, thereby enhancing the sealing between the supporting surface and the discharge surface. This is particularly important when a certain amount of powder accumulates on the supporting surface and the discharge surface over long-term use. The flexible contact ensures that the accumulated powder does not easily wear out the connection between the supporting surface and the discharge surface. Of course, the flexible structure 720 can also be provided independently of the discharge surface and the supporting surface, located between them.

[0384] It should be noted that the flexible structure 720 is configured to seal the gap between the cover plate and the discharge channel opening when the cover plate closes the discharge channel opening. At this time, the above-mentioned flexible contact can be the exact contact between the bearing surface and the discharge surface, and the two do not deform at the flexible structure 720, or produce a small deformation that is almost negligible. Or in one embodiment, when the cover plate 112 moves to the closed position, the discharge surface and the bearing surface are in interference contact at the flexible structure 720. Interference contact, that is, a relatively large degree of deformation occurs between the bearing surface and the discharge surface, which helps to further increase the sealing contact effect between the bearing surface and the discharge surface.

[0385] Furthermore, the flexible structure 720 can be provided in a localized area between the load-bearing surface and the discharge surface, or can be provided throughout the entire area of ​​the load-bearing surface and the discharge surface. In one specific application, the flexible structure 720 is provided at least around the periphery of the discharge channel opening. This allows the flexible structure 720 to be effective in all directions along the entire periphery of the discharge channel opening, thereby enhancing the sealing effect of the load-bearing surface and the discharge surface along the entire periphery of the discharge channel opening.

[0386] Based on the above, when the weighing module is provided with the flexible structure 720, it can be understood that the weighing module can also be provided with the scraping member 710 described above. Alternatively, in one embodiment, the receiving container 110 further includes a connecting seat 113, and the cover plate is movably mounted on the connecting seat 113. When the cover plate is moved along the first horizontal direction to open the discharge channel opening, the cover plate is scraped by the discharge channel opening and / or the connecting seat 113. In other words, the discharge channel opening and / or the connecting seat 113 directly play the scraping role of the scraping member 710 described above.

[0387] It should be emphasized that the beverage preparation equipment in the present application can be a bean grinder for grinding coffee beans, the weighing module can be arranged in the coffee bean grinder, the grinder is provided with a grinding module, the weighing module and the setting are matched with the grinding module of the grinder, the installation and control method of the weighing module in the grinder are the same as above, and the powder material weighed by the weighing module can be received by the powder bowl and then brewed manually.

[0388] Fifth application example:

[0389] Referring to Figures 1-3, 5-8, and 10-16, this application provides a beverage preparation device comprising a body and a weighing module. The body comprises at least a housing defining an inner cavity, a grinding module disposed within the inner cavity, and a brewing module, the body being provided with a mating structure. Furthermore, to enable intelligent and automatic operation of the beverage preparation device, the body may further include a control device housed within the inner cavity of the housing and / or a display module at least partially exposed on the outer wall of the housing.

[0390] This design does not limit the specific type of beverage preparation device; it can be any device or product that can extract and brew materials to ultimately produce a beverage. Specifically, the beverage preparation device can be, but is not limited to, a coffee machine, a soymilk maker, etc. Correspondingly, the materials referred to in this application can be beans such as coffee beans and soybeans. For ease of understanding, the following embodiments are described using a coffee machine as the beverage preparation device, where the materials include coffee beans that have not been ground by the grinding module, as well as coffee powder obtained after grinding by the grinding module.

[0391] The grinding module may include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder defines a grinding chamber; the grinding mechanism includes, for example, a movable cutting tool and a first drive assembly that actuates the cutting tool. The cutting tool can be designed with a desired shape and suitable motion to facilitate puncturing, grinding, stirring, and other crushing operations on granular materials such as coffee beans. Examples of these tools include bayonets and blade discs. The outlet of the grinding module refers to the outlet of the grinding cylinder.

[0392] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee beverage. The brewing mechanism is mainly configured as a pressing mechanism, a heating mechanism and / or a water supply component according to different brewing requirements. In addition, the brewing mechanism can also be configured as, but is not limited to, a refrigeration mechanism and / or a milk supply component, etc. according to actual needs, to obtain different types of coffee beverages. The inlet end of the brewing module refers to the inlet end of the brewing cylinder.

[0393] In view of the above, the following is specifically described by taking as an example a beverage preparation device in which the body includes a grinding module and a brewing module, and the weighing module is arranged between the outlet end of the grinding module and the inlet end of the brewing module:

[0394] Please refer to Figures 1 to 2. The present application also provides a weighing module, which is used in the above-mentioned beverage preparation equipment and is specifically accommodated in the inner cavity of the casing. The weighing module can be set between the outlet end of the grinding module and the inlet end of the brewing module in the body. The inlet end of the weighing module can be connected to the outlet end of the grinding module in an on-off manner, and the outlet end of the weighing module can be connected to the inlet end of the brewing module in an on-off manner. Among them, when the weighing module moves close to the grinding module manually or automatically driven by a preset power module, it is in a powder receiving position, the inlet end of the weighing module is connected to the outlet end of the grinding module, and when the outlet end of the weighing module is disconnected from the inlet end of the brewing module, the weighing module can receive and accommodate the coffee powder discharged outward from the outlet end of the grinding module, and perform the weighing function simultaneously or with a delay. When the inlet of the weighing module is connected to the outlet of the grinding module, and the outlet of the weighing module is connected to the inlet of the brewing module, the weighing module primarily serves as a transition point for the powdered material and does not perform a weighing function. When the weighing module is moved manually or automatically by a preset power module toward the brewing module, it is in the brewing position and can transfer the powdered material pre-loaded in the weighing module to the brewing module.

[0395] It should be noted that when the weighing module is used in a beverage preparation device, it can be assembled into the body in any suitable posture according to actual needs. For ease of understanding, in the following embodiments, the beverage preparation device as a whole and its components have approximately perpendicular horizontal and vertical directions. The vertical direction is also approximately vertical. The horizontal direction is any suitable direction on the horizontal plane, which can specifically be a first horizontal direction and a second horizontal direction arranged in a cross pattern. The angle between the first horizontal direction and the second horizontal direction can be set to approximately 90°.

[0396] When the weighing module is used in a beverage preparation device, it is placed in the machine body as a modular component. The plug-in structure of the weighing module and the matching structure of the machine body can be quickly disassembled and assembled. When the weighing module is installed in the housing and located between the grinding module and the brewing module, the current position of the weighing module constitutes the preset installation position:

[0397] In one embodiment, when the weighing module is removed from the machine body, the pre-set installation position becomes vacant, creating a gap between the grinding module and the brewing module. Optionally, a plug-in structure can also be provided on the grinding module and / or the brewing module. Based on this plug-in structure, the grinding module and / or the brewing module can be plugged into a mating structure on the machine body to replace the pre-set installation position, thereby placing the brewing module and the grinding module as close together as possible to prevent powder from scattering during transfer.

[0398] Alternatively, in one embodiment, a detachable or integral, deformable connecting structure can be provided between the grinding module and / or the brewing module. When the weighing module is installed in the housing, the connecting structure compresses and deforms; conversely, when the weighing module is removed from the housing, the connecting structure extends and deforms, connecting the outlet of the grinding module with the inlet of the brewing module, thereby preventing a gap from forming between the grinding module and the brewing module. The connecting structure can be a soft rubber channel, etc., and its specific form is not limited.

[0399] Based on this, further, in one embodiment, the beverage preparation device can also identify whether the weighing module is installed in the casing through its own preset or externally connected control device, combined with one or several sensor devices, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0400] In view of the above, it can be seen that the beverage preparation device and / or the weighing module are pre-set with optional weighing mode and non-weighing mode. In actual application, the beverage preparation device can adjust whether the whole machine is currently in weighing mode or non-weighing mode by manual setting based on, for example, preset buttons. Among them, when the whole machine is in non-weighing mode, the weighing component can be in an uninstalled state when it is removed from the inside of the casing, or it can be in an installed state installed in the casing. When the weighing module is in an installed state installed in the casing, the weighing module can be used as a transfer mechanism for conveying powder from the grinding module to the brewing module as described above. The weighing module is set to a normally open form, which is equivalent to a connecting pipeline. When the powder is conveyed from the grinding module to the brewing module, the powder passes through the weighing module freely and unobstructed.

[0401] Specifically, the plug-in structure and the matching structure complement each other in terms of setting quantity, setting orientation, structural type, etc., and with the coordination of the two, the weighing module can move into the inner cavity of the casing along a specified direction under the drive of external force, and move out from the inner cavity of the casing along a specified direction.

[0402] First, referring to Figures 2 to 10, in one embodiment, the weighing module includes a receiving container 110, a driving device 120, and a weighing device 130. The receiving container 110 includes a container body 111 and an opening and closing member. The container body 111 is provided with a material delivery channel 111a for connecting the outlet end of the grinding module and the inlet end of the brewing module. The opening and closing member is movably arranged relative to the container body 111, so as to have an open position that connects the material delivery channel 111a and a closed position that blocks the material delivery channel 111a. The driving device 120 is drivingly connected to the opening and closing member. The weighing device 130 includes a weighing portion 131 and a fixing portion 132 located at two ends. The weighing portion 131 is fixedly connected to the receiving container 110, and the fixing portion 132 is fixedly connected to the driving device 120. The weighing portion 131 and the fixing portion 132 are located at two ends of the weighing device 130 extending along a first horizontal direction.

[0403] The container body 111 is generally cylindrical, with the space within the cylinder directly defining a feed channel 111a. The feed channel 111a can extend in a direction as needed, for example vertically or in a direction inclined relative to the vertical. Of course, the feed channel 111a can be configured as a straight channel structure or, depending on actual needs, as a channel structure that is at least partially curved.

[0404] The opening and closing member can be positioned anywhere within the feed channel 111a, for example, at the inlet end, at the outlet end, or anywhere between the inlet and outlet ends of the feed channel 111a. For example, as shown in Figures 3 to 5 , the opening and closing member is positioned at the outlet end of the feed channel 111a and externally positioned within the container body 111. The opening and closing member is generally plate-shaped. The shape and dimensions of the portion of the opening and closing member that covers the outlet end of the feed channel 111a can be adapted to that of the outlet end.

[0405] There is no restriction on the movement of the opening and closing member relative to the container body 111:

[0406] In one embodiment, the opening and closing member can be flipped relative to the container body 111. Specifically, one end of the opening and closing member is rotatably connected to an edge of the outlet end of the material delivery channel 111a, and the other end of the opening and closing member can flip to a closed position toward the other edge of the outlet end of the material delivery channel 111a, and flip to an open position toward the other edge of the outlet end of the material delivery channel 111a.

[0407] Alternatively, in the embodiments shown in Figures 3 to 5, the opening and closing member can be translated relative to the container body 111. Specifically, the opening and closing member is offset to one side of the outlet end of the material delivery channel 111a and can be translated to a closed position toward the other side of the outlet end of the material delivery channel 111a, and can be translated to an open position away from the other side of the outlet end of the material delivery channel 111a.

[0408] The configuration of the drive mechanism 120 is related to the movement of the opening and closing member. The drive mechanism 120 includes at least a drive assembly, which is operatively connected to the opening and closing member to drive the opening and closing member to move back and forth between a closed position and an open position. The fixing portion 132 can be connected to a portion of the drive assembly that is not connected to the opening and closing member and is relatively fixed, such as the housing structure.

[0409] Alternatively, referring specifically to Figures 6 to 8 , in one embodiment, the drive device 120 includes a docking station 121 and a drive assembly. The docking station 121 is connected and fixed to a fixing portion 132. Specifically, in one application, the fixing portion 132 is disposed at one end of the top of the docking station 121. The drive assembly is disposed on the docking station 121 and is detachably connected to the opening and closing member. When the drive assembly is connected and drives the opening and closing member to the open position, it remains connected to the opening and closing member. After the drive assembly is connected and drives the opening and closing member to the closed position, the drive assembly disconnects from the opening and closing member and separates from each other, entering a non-contact state. Specifically, the drive device 120 can be continuously operated in the same direction or disengaged from the opening and closing member in the opposite direction. A receiving cavity can be formed within the docking station 121. The docking station 121 can be configured as a closed structure, with the drive assembly at least partially sealed within the receiving cavity. The provision of the docking station 121 provides a connection space for the fixing portion 132 that is independent of the drive assembly, while also providing a secure, sealed receiving space for the drive assembly.

[0410] It should be emphasized that in one application, the weighing device 130 is roughly cantilevered. This design, by locating the drive assembly at the docking station 121 and connecting the fixing portion 132 to the docking station 121, allows the drive assembly to directly apply downward force to the fixing portion 132, bearing only the container body 111 and the powder contained therein. Compared to conventional solutions in which the drive assembly and container body 111 are integrally arranged in the weighing unit 131, the weighing unit 131 in this design bears virtually no weight of the drive assembly. This effectively prevents the heavier drive assembly from placing a load on the weighing unit 131, thereby ensuring that the weighing results of the weighing unit 131 in this design are more sensitive and accurate. Furthermore, vibrations generated by the drive assembly during operation are effectively prevented from causing measurement deviations in the weighing unit 131, thereby ensuring that the weighing process of the weighing unit 131 in this design is more stable and efficient.

[0411] Since the weighing device 130 is roughly in the shape of a cantilever extending along the first horizontal direction, its weighing part 131 and fixing part 132 are respectively arranged at the two ends of the first horizontal direction. Therefore, in actual application, please refer to Figures 1 and 16, the weighing part 131 is connected to the receiving container 110, and at least the part of the receiving container 110 connected to the weighing part 131 can be suspended vertically below the weighing part 131, or it can be supported vertically above the weighing part 131. Similarly, the fixing part 132 is connected to the driving device 120, and the part of the driving device 120 that can be connected to the fixing part 132 can be connected vertically below the fixing part 132, or it can be connected vertically above the fixing part 133.

[0412] When at least the portion of the receiving container 110 connected to the weighing unit 131 is supported vertically above the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing pressure changes. When at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, the weighing unit 131 is generally configured to measure weight by sensing tension changes.

[0413] The portion where the receiving container 110 is connected to at least the weighing part 131, and the portion where the driving device 120 / fixed carrier is connected to at least the fixing part 132, can be arranged on both sides of the weighing device 130 in the vertical direction, or can be located on the same side of the weighing device 130 in the vertical direction.

[0414] However, for ease of understanding, the following embodiments are described as follows, assuming that at least the portion of the receiving container 110 connected to the weighing unit 131 is suspended vertically below the weighing unit 131, and at least the portion of the driving device 120 connected to the fixing unit 132 is connected vertically below the fixing unit 132. Specifically, as shown in Figures 8 to 10, the connecting base 113 is suspended below the weighing unit 131 and is fixedly connected to the lower end of the weighing unit 131.

[0415] Furthermore, in one embodiment, the receiving container 110 further includes a connecting seat 113 extending below the weighing device 130 and connected to the weighing device 130. The container body 111 and the weighing part 131 are connected and fixed to the connecting seat 113. In other embodiments, the container body 111 can also be directly connected to the weighing part 131, and the connecting seat 113 can be fixed to the container body 111 and / or the weighing part 131, or the weighing part 131 can be independently provided. The opening and closing member can be installed on the connecting seat 113 in a first horizontal direction close to and away from the container body 111. The projection of the weighing device 130 on the horizontal plane is completely located within the projection plane of the connecting seat 113 on the horizontal plane. The driving assembly includes a driver 122 and a rotating member 1 23. The driver 122 and the fixing portion 132 are both connected and fixed to the docking seat 121. The driver 122 is driven and connected to the rotating member 123. One of the connection points between the rotating member 123 and the opening and closing member is provided with a guide groove 114b extending along a second horizontal direction intersecting the first horizontal direction, and the other is provided with a guide protrusion 123a. During the rotation of the rotating member 123, the guide protrusion 123a has a first stroke section that contacts the guide groove 114b and slides along the guide groove 114b, and a second stroke section that is out of contact with the guide groove 114b. The driving component can be separated from the closing member in the installation direction of the opening and closing member. At the same time, before driving the opening and closing member to execute the instruction to open or close the container body 111, it is in a separated state from the opening and closing member.

[0416] The driver 122 performs a rotational output and can be a motor or a combination of a motor and a transmission assembly. The transmission assembly can be, for example, a gear set, a worm gear mechanism, or the like. The rotating member 123 is connected to the rotational output shaft of the driver 122 so that, under the rotational drive of the rotational output shaft of the driver 122, the rotating member 123 can be driven by the driver 122 to rotate in the same direction, ultimately driving the guide protrusion 123a to slide against and contact the guide groove 114b. Since the guide groove 114b extends along the second horizontal direction, the rotational motion of the rotating member 123 can be converted into a translational motion that pushes the guide groove 114b along the first horizontal direction and the movement of the protrusion of the rotating member 123 within the guide groove 114b toward the second horizontal direction, ultimately achieving the purpose of driving the opening and closing member to perform translational movement along the first horizontal direction. The second horizontal direction in which the guide groove 114b extends is perpendicular to the first horizontal direction of the translational motion of the guide groove 114b. In the above description, when the guide protrusion 123a is in the first stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a mutually contacting and connected state, and the driving force of the driver 122 can ultimately be transmitted to the opening and closing member, thereby switching the opening and closing member between the open position and the closed position. When the guide protrusion 123a is in the second stroke segment, the driver 122, the rotating member 123, and the opening and closing member are in a disconnected state, and the driving force of the driver 122 cannot be transmitted to the opening and closing member, and the opening and closing member is locked in the current position (specifically, the closed position). At this time, the driving device 120 and the receiving container 110 remain substantially separated. The driving device 120 independently applies force to the fixing portion 132 of the weighing device 130, and the receiving container 110 independently applies force to the weighing portion 131 of the weighing device 130. This helps to prevent the gravity of the driving device 120 from affecting the measured weight of the material received by the receiving container 110, thereby further helping to improve the weighing accuracy and optimize the weighing effect.

[0417] It should be noted that when the guide protrusion 123a is in the first travel segment, the guide protrusion 123a is in sliding engagement with at least the sidewall of the guide groove 114b. Optionally, the top of the guide protrusion 123a can be in sliding engagement with the bottom wall of the guide groove 114b, thereby ensuring a smoother sliding connection between the guide protrusion 123a and the guide groove 114b. Alternatively, the top of the guide protrusion 123a can be spaced apart from the bottom wall of the guide groove 114b, thereby ensuring that the connecting base 113 remains suspended above the guide protrusion 123a and the docking base 121. In this manner, apart from the weighing portion 131 in direct contact with the container body 111 and the fixing portion 132 in direct contact with the docking base 121, no other components come into contact with the weighing device 130. This minimizes any other contact during weighing by the weighing device 130, thereby ensuring accurate weighing.

[0418] In a preferred embodiment, the guide protrusion 123a may include a boss and a ring sleeved on the outer circumference of the boss, wherein the ring can be sleeved on the boss and rotate around the boss, and the ring contacts and drives the opening and closing part to move in the guide groove 114b. The diameter of the ring is smaller than the width of the guide groove 114b. The friction force formed by the contact of the ring driving the guide groove 114b is converted into rolling friction force, thereby reducing the friction generated and preventing wear and friction noise caused by long-term contact friction.

[0419] Further, referring to Figures 6 to 8, in one embodiment, the outer top wall of the docking seat 121 is provided with a circular limiting hole 121f extending therethrough and an arc-shaped groove 121a provided on the outer periphery of the limiting hole 121f. The arc length of the arc-shaped groove 121a is not less than the arc length corresponding to the guide protrusion 123a when performing the first stroke segment. The rotating member 123 includes a rotating arm 123c and a rib 123d protruding downward from the bottom end of the rotating arm 123c to extend into the arc-shaped groove 121a. A rotating boss 123e is provided at one radial end of the rotating arm 123c, facing toward the docking seat 121. Rotating boss 123e is rotatably connected to a limiting hole 121f in the docking seat 121. A guide boss 123a is provided at the other radial end of the rotating arm 123c, facing away from the docking seat 121, and a rib 123d slides along the side walls of the arcuate groove 121a. The driver 122 is housed within the docking seat 121, with the drive shaft extending upward and outward from the limiting hole 121f. To enhance the structural strength of the rotating arm 123c, in one embodiment, the rotating member 123 may further include fan-shaped plates 123b extending from both sides of the rotating arm 123c.

[0420] In one embodiment of the present application, the rotating boss 123e is mounted on the drive shaft of the driver 122 and is located above the limiting hole 121f. The outer diameter of the rotating boss 123e is larger than the aperture of the limiting hole 121f, so that the rotating boss 123e can cover the area above the limiting hole 121f. In another embodiment, the rotating boss 123e extends into the limiting hole 121f, wherein the outer diameter of the rotating boss 123e substantially matches the aperture of the limiting hole 121f, so that the rotating boss 123e fills the entire limiting hole 121f.

[0421] Specifically, the arcuate groove 121a can be arranged along the entire circumference of the rotation axis of the rotating member 123. In the embodiment of the present application, the rotation axis is consistent with the direction of gravity of the driving device 120, so that the rib 123d can slide along the entire circumference of the side groove wall of the arcuate groove 121a, thereby achieving unidirectional and full-circumferential rotation of the rotating member 123. Alternatively, the arcuate groove 121a can be arranged partially along the circumference of the rotation axis of the rotating member 123, so that when the rib 123d slides along the side groove wall of the arcuate groove 121a, the rotating member 123 can achieve unidirectional rotation of a limited arc length segment.

[0422] The plate 123b, rotating arm 123c, rib 123d, and guide protrusion 123a of the rotating member 123 can be integrally formed, or they can be formed separately and then removably or non-removably connected and fixed. The provision of the rotating arm 123c and rib 123d helps to reduce material consumption of the rotating member 123 and prevents excessive sliding connection between the rotating member 123 and the guide groove 114b and the arcuate groove 121a, which would increase sliding losses.

[0423] It should be noted that, in order to allow the guide protrusion 123a to extend into and out of the guide groove 114b, in one embodiment, the outer peripheral surface of the guide protrusion 123a and / or the corresponding side groove wall of the guide groove 114b can be configured as an inclined straight surface or an arcuate surface to provide smooth guidance. Alternatively, in one embodiment, the rotating member 123 can be telescopically mounted on the docking seat 121 relative to its own rotational axis, and the arcuate groove 121a can be configured with a gradually increasing depth in the portion corresponding to the second stroke segment.

[0424] As can be seen from the above, the rotation of the rotating member 123 simultaneously drives the guide protrusion 123a to slide along the guide groove 114b, and simultaneously drives the rib 123d to slide along the arcuate groove 121a. Therefore, in order to limit the rotation angle range of the rotating member 123, the sliding strokes of the rotating member 123 itself, the guide protrusion 123a and the guide groove 114b, and the sliding strokes of the rib 123d and the arcuate groove 121a can be specifically configured.

[0425] In view of the above, when the opening and closing member translates along the first horizontal direction, the guide groove 114b extends approximately along a second horizontal direction perpendicular to the first horizontal direction. In this case, the guide groove 114b includes at least a first side groove wall and a second side groove wall disposed opposite each other in the first horizontal direction, and both the first side groove wall and the second side groove wall extend along the second horizontal direction. If the distance between the first side groove wall and the second side groove wall, i.e., the groove width of the guide groove 114b, is k, and the length of the guide protrusion 123a of the rotating member 123 along the first horizontal direction, i.e., the radius of the guide protrusion 123a when the guide protrusion 123a is a cylinder, is r, then k is greater than 2 times r. That is, when the guide protrusion 123a is located between the first side groove wall and the second side groove wall, it can only abut against the first side groove wall or the second side groove wall. When the guide protrusion 123a abuts against the first side groove wall or the second side groove wall, the gap between the guide protrusion 123a and the other side groove wall is t. This helps to avoid excessive friction interference between the guide protrusion 123a and the guide groove 114b, ensuring that the guide protrusion 123a can slide along the guide groove 114b.

[0426] If the rotation radius of the guide protrusion 123a, that is, the distance from the rotation center of the rotating member 123 to the center of the guide protrusion 123a is L, and the moving path length of the rotating member 123 driving the opening and closing member is S, then S=2L-k.

[0427] 11 to 14 , if it is defined that when the guide protrusion 123a slides in the guide groove 114b to the first limit position, the opening and closing member is in the open position; when the guide protrusion 123a slides in the guide groove 114b to the second limit position, the opening and closing member is in the closed position.

[0428] In one embodiment, the driver 122 is configured to stop operating immediately when the guide protrusion 123a is driven to move to the first limit position or the second limit position.

[0429] Alternatively, in one embodiment, the driver 122 is configured to continue operating when the guide protrusion 123a is moved to the first limit position or the second limit position, and the driver 122 stops operating after the guide protrusion 123a continues to slide to a certain stroke.

[0430] It should be noted that there are multiple ways to stop the control driver 122:

[0431] In one embodiment, the target rotation angle can be determined by calculating the rotation angle range of the driver 122. For example, based on the structural design parameters of the guide groove 114b, the guide protrusion 123a, etc., the required rotation angle for the guide protrusion 123a to move to the first limit position or the second limit position is calculated, and then the target rotation angle is used as the target rotation angle to control the driver 122 to stop operation.

[0432] Alternatively, in one embodiment, the rotation angle range of the rotating member 123 may be determined by limiting the rotation angle range of the rotating member 123. Specifically, the rotation angle range of the rotating member 123 may be set to be greater than 180° and less than 360°. When the rotation angle range is exceeded, the driver 122 is controlled to stop operating.

[0433] Alternatively, in one embodiment, an additional stop structure can be provided to mechanically stop the rotation of the rotating member 123 or the output shaft. Specifically, the stop structure can be provided, for example, within the guide groove 114b at a predetermined position corresponding to the sliding path of the guide protrusion 123a, or on the docking station 121 at a predetermined position corresponding to the rotation path of the rotating member 123.

[0434] Alternatively, in one embodiment, a sensor may be provided to determine the active position of the guide protrusion 123a and / or the rotating member 123. Furthermore, in the above embodiment, the driving device 120 further includes a position sensor 121b, and the driving device 120 further includes a triggering portion that is linked to the output shaft. The position sensor 121b is disposed on one side of the triggering portion. When the output shaft rotates until it is disconnected from the opening and closing member, it drives the triggering portion to move until it triggers the position sensor 121b. The position of the triggering portion constitutes a stop position.

[0435] Specifically, in conjunction with Figures 6 and 15 , in one embodiment, the docking station 121 is provided with a position sensor 121b protruding from the side of the arcuate groove 121a. The position sensor 121b is provided with a sensing portion 121c. The sensing portion 121c can be provided protruding from the side surface of the position sensor 121b facing the arcuate groove 121a. The sensing portion 121c and the position sensor 121b can be integrally formed, or they can be separately formed and then removably or non-removably connected and fixed. The sensing portion 121c can specifically be provided with a through-slot 121d. The through-slot 121d is adapted to be provided at the corresponding outer periphery of the rotating member 123. The through-slot 121d can, to a certain extent, limit the rotation of the rotating member 123 along its rotation axis without affecting the rotation of the rotating member 123. A trigger portion is provided on the rotating member 123 or the output shaft corresponding to the sensing portion 121c. When the trigger portion approaches the sensing portion 121c, the position sensor 121b is triggered to generate a sensing signal.

[0436] One sensing portion 121c can be provided, and correspondingly, one position sensor 121b can be provided. In this case, one stop position is provided. It can be understood that whether the guide protrusion 123a rotates to separate from the guide groove 114b after moving from the open position to the closed position, or whether the guide protrusion 123a rotates to separate from the guide groove 114b after moving from the closed position to the open position, the trigger portion is driven to the same stop position.

[0437] Of course, two sensing parts 121c can also be provided, with the two sensing parts 121c corresponding to one or two position sensors 121b. In this case, there are two corresponding stop positions, namely, a first stop position, in which the trigger part is located when the guide protrusion 123a rotates to separate from the guide groove 114b after moving from the closed position to the open position; and a second stop position, in which the trigger part is located when the guide protrusion 123a rotates to separate from the guide groove 114b after moving from the open position to the closed position. The two position sensors 121b are respectively provided at the first stop position and the second stop position. The first stop position and the second stop position are spaced apart from each other, so that the output shaft does not need to drive the rotating member 123 to rotate a full circle, and only switches between the first stop position and the second stop position.

[0438] The position sensor 121b is used to detect the position of the driving device 120 when it is triggered when the rotating part 123 of the driving device 120 drives the opening and closing parts, or when the rotating part 123 is started to prepare to move from the separation state to the contact opening and closing state. In this way, by setting two position sensors 121b, it is possible to accurately detect whether the rotating part 123 of the driving device 120 is in the separation position state after the open position or in the separation position state after the closed position.

[0439] It should be noted that when the driver 122 is configured to continue to operate for a certain distance after driving the guide protrusion 123a to the first or second limit position before stopping, in one embodiment, the guide protrusion 123a can be configured to disengage from the guide groove 114b after sliding for the distance, thereby completing the clutch connection between the rotating member 123 and the opening and closing member. There are various ways to disengage, such as gradually reducing the groove depth of the corresponding groove section of the guide groove 114b so that the guide protrusion 123a is gradually pushed out of the guide groove 114b; or the guide groove 114b can be configured to be open at both ends in the second direction so that the guide protrusion 123a can disengage from the guide groove 114b outward from the open ends.

[0440] Furthermore, based on the above, and in conjunction with Figures 3 to 5 , in one embodiment, the connecting base 113 is provided with a mounting slot 113a, within which a guide rod 115 is disposed, extending along a first horizontal direction. The opening and closing member may specifically include a cover plate 112 and a slider 114. The cover plate 112 covers the notch of the mounting slot 113a and is provided with a mounting hole 112a extending therethrough and communicating with the mounting slot 113a. The slider 114 is received within the mounting slot 113a and partially extends outward from the mounting hole 112a. The slider 114 is fixed relative to the cover plate 112. The portion of the slider 114 within the mounting slot 113a is provided with a guide hole 114a for slidably engaging with the guide rod 115. The portion of the slider 114 extending outside the mounting slot 113a is provided with the guide slot 114b or the guide protrusion 123a. The number of guide rods 115 provided may be one or multiple guide rods 115 extending side by side in the same direction. The guide holes 114 a are suitable for adaptively adjusting the number and positions of the guide rods 115 .

[0441] Of course, in one embodiment, the opening and closing member may specifically include a cover plate 112 and a slider 114, and the slider 114 is fixedly connected to one side of the cover plate 112 covering the mounting groove 113a and is not exposed on the outside of the cover plate 112. At this time, the above-mentioned guide groove 114b or the guide protrusion 123a may be provided on the side of the cover plate 112 facing away from the mounting groove 113a.

[0442] In addition, in one embodiment, the weighing device 130 is suspended in the inner cavity of the machine body and is roughly cantilevered. When the weighing module does not carry any material, the counterweight of the weighing part 131 of the weighing device 130 is set to be equivalent to the counterweight of the fixed part 132, or the counterweight of the weighing part 131 of the weighing device 130 is set to be smaller than the counterweight of the fixed part 132. That is, when the weighing module does not carry any material, the structural design is to set the weighing part 131 and the fixed part 132 of the weighing device 130 to be balanced with each other, or at least the weighing part 131 is smaller, so as to avoid the unbalanced force between the weighing part 131 and the fixed part 132 of the weighing device when not weighing, which may cause the cantilever weighing device to deflect, and easily reduce the weighing accuracy of the weighing device after long-term use.

[0443] It should be emphasized that the beverage preparation equipment in the present application can be a bean grinder for grinding coffee beans, the weighing module can be arranged in the coffee bean grinder, the grinder is provided with a grinding module, the weighing module and the setting are matched with the grinding module of the grinder, the installation and control method of the weighing module in the grinder are the same as above, and the powder material weighed by the weighing module can be received by the powder bowl and then brewed manually.

[0444] In addition, based on any of the above embodiments, the weighing module may be internally or externally connected to a control device 800 . And / or when the weighing module is used in a beverage preparation device, the beverage preparation device may be internally or externally connected to a control device 800 .

[0445] The control device 800 is electrically connected to the weighing module, for example, the driving device 120 in the weighing module. The control device 800 can also be electrically connected to the grinding module, brewing module, position sensor 121b, etc. as needed.

[0446] The control device 800 includes a memory 850 , a processor 810 , and a control program for the weighing module and / or a control program for the beverage preparation device stored in the memory 850 and executable on the processor 810 .

[0447] 22 to 23 , which are schematic diagrams of the structure of a control device 800 for a hardware operating environment according to an embodiment of the present application.

[0448] As shown in Figures 22 and 23, the control device 800 may include: a processor 810, such as a central processing unit (CPU), a communication bus 820, a user interface 830, a network interface 840, and a memory 850. The communication bus 820 is used to enable communication between these components. The user interface 830 may include a display and an input unit, such as a keyboard. Optionally, the user interface 830 may also include a standard wired interface or a wireless interface. The network interface 840 may optionally include a standard wired interface or a wireless interface (such as a wireless fidelity (WI-FI) interface). The memory 850 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 850 may be a storage device independent of the processor 810.

[0449] Those skilled in the art will understand that the structures shown in Figures 22 to 23 do not constitute a limitation on the control device 800, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0450] As shown in FIG. 22 and FIG. 23 , the memory 850 as a storage medium may include an operating system, a network communication module, a user interface 830 module, and a control program for a weighing module and / or a control program for a beverage preparation device.

[0451] In the control device 800 shown in Figures 22 to 23, the network interface 840 is mainly used for data communication with the network server; the user interface 830 is mainly used for data interaction with the user; the processor 810 and the memory 850 in the control device 800 of the present application can be set in the weighing module and / or the beverage preparation equipment. The control device 800 calls the control program of the weighing module and / or the control program of the beverage preparation equipment stored in the memory 850 through the processor 810, and executes the control method of the weighing module and / or the control method of the beverage preparation equipment provided in the embodiment of the present application separately or simultaneously.

[0452] In view of the above beverage preparation device, it can be known that in specific applications, the beverage preparation device is pre-set with multiple functional modes, such as weighing mode, pre-load mode and non-weighing mode, and various modes are available for users to freely choose.

[0453] It can be understood that the weighing mode is a mode that requires the weighing module to run its own weighing function.

[0454] Based on this, referring to FIG. 24 , the control method of the beverage preparation device includes:

[0455] Step G100: When the weighing mode is selected, the weighing module is controlled to execute the weighing module control method described below.

[0456] Specifically, the control method of the weighing module includes:

[0457] Step G110: upon receiving the opening instruction, controlling the driving device 120 to drive the opening and closing member to move to the open position at a first speed;

[0458] In this embodiment, the opening instruction can be manually entered by the user, for example, manually input through a control panel set on the body, triggered input through a mobile terminal connected to the control device 800, etc., without limitation.

[0459] Alternatively, the opening instruction may be related to the motion state, position state, working state, etc. of certain components of the weighing module. Specifically, for example, it may be related to the position state of the container body 111. For example, in one embodiment, the control method of the beverage preparation device further includes:

[0460] Step G1101: When the weighing mode is selected and the opening instruction is triggered automatically or manually when or after the container body 111 is determined to move to the brewing position and / or when or before the brewing module starts to operate.

[0461] It can be understood that by monitoring the driving state of the power module that drives the container body 111 to move, or by using the sensing results of a specially provided sensor device, it can be determined whether the container body 111 has moved to the brewing position. Similarly, it can also be determined whether the brewing module has started to run. When the container body 111 moves from the powder receiving position toward the brewing position until it just reaches the brewing position, the opening instruction is triggered; or when the container body 111 moves from the powder receiving position to the brewing position, the opening instruction is triggered after a preset time; or when the container body 111 moves from the powder receiving position to the brewing position, the opening instruction is triggered while determining that the brewing module has just started to run; or when the container body 111 moves from the powder receiving position to the brewing position, the opening instruction is triggered within a preset time before determining that the brewing module has started to run. In this process, the opening instruction can be manually triggered by the user or pre-compiled by the program.

[0462] Step G120: upon receiving the closing instruction, controlling the driving device 120 to drive the opening and closing member to move to the closed position at a second speed; wherein the second speed is greater than the first speed.

[0463] In this embodiment, similarly, the closing instruction can be manually entered by the user, for example, manually input through a control panel set on the body, triggered input through a mobile terminal connected to the control device 800, etc., without limitation.

[0464] Alternatively, the closing instruction may be related to the motion state, position state, working state, etc. of certain components of the weighing module. Specifically, for example, it may be related to the position state of the container body 111. For example, in one embodiment, the control method of the beverage preparation device further includes:

[0465] Step G1201: When the weighing mode is selected and the container body 111 is determined to move to the powder receiving position, and / or before or after the grinding module starts to operate, the closing instruction is automatically or manually triggered.

[0466] It can be understood that by monitoring the driving state of the power module that drives the container body 111 to move, or by means of the sensing results of a specially provided sensor device, it can be determined whether the container body 111 has moved to the powder receiving position. Similarly, it can also be determined whether the grinding module has started to start running. When the container body 111 moves from the brewing position or other positions toward the powder receiving position until it just reaches the powder receiving position, the closing instruction is triggered; or when the container body 111 moves from the brewing position or other positions to the powder receiving position, the opening instruction is triggered; or when it is determined that the grinding module has just started to run, the closing instruction is triggered; or within the preset time before it is determined that the grinding module has started to run, the closing instruction is triggered. In this process, the closing instruction can be manually triggered by the user or pre-compiled by the program.

[0467] In the technical solution provided by the present application, a closing instruction is generally triggered when or before the weighing module is required to measure the weight of the powder discharged by the grinding module, for example. At this time, since the powder ground by the grinding module is generally discharged in real time, the driving device 120 needs to relatively quickly and promptly drive the opening and closing member to the closed position so that it can smoothly receive the powder to be measured. When the weight measurement operation is completed, the powder needs to be transferred, for example, to the brewing module, and an opening instruction is triggered. At this time, since the brewing operation of the brewing module does not start in real time, the driving device 120 can drive the opening and closing member to the open position at a relatively slow speed, leaving sufficient time for the powder to be transferred, thereby preventing the powder from accumulating and remaining in the feeding channel 111a or at the opening and closing member. In this way, the opening and closing speeds of the opening and closing member can be made more suitable for actual application requirements, and help improve the opening and closing efficiency of the opening and closing member, and ultimately help improve the operating efficiency of the weighing module.

[0468] Furthermore, in one embodiment, the driving device 120 includes a driver 122, wherein the driver 122 has a rotatable output shaft, and the output shaft is detachably connected to the opening and closing member; the control method of the weighing module further includes:

[0469] Step G130: After moving to the open position or the closed position, controlling the output shaft to rotate in the same direction at a third speed for a first stroke until the output shaft is disconnected from the opening and closing member.

[0470] In this embodiment, using the aforementioned guide protrusion 123a and guide groove 114b as an example, after executing step G110, the control device 800 controls the output shaft to drive the guide protrusion 123a to slide along the guide groove 114b to the first position, thereby moving the opening and closing member to the open position. The control device 800 then controls the output shaft to rotate in the same direction to the first stroke. During this first stroke, the guide protrusion 123a continues to slide from the first position until it exits the guide groove 114b, thereby separating the rotating member 123 from the opening and closing member.

[0471] Similarly, after executing step G120, the control device 800 controls the output shaft to drive the guide protrusion 123a to slide along the guide groove 114b to the second position, thereby moving the opening and closing member to the closed position. The control device 800 then controls the output shaft to rotate in the same direction to the first stroke. During this first stroke, the guide protrusion 123a continues to slide from the second position to exit the guide groove 114b, thereby separating the rotating member 123 from the opening and closing member.

[0472] Specifically, it can be understood that the purpose of the first stroke is to achieve the separation of the rotating member 123 and the opening and closing member, which is basically unrelated to the main function of the driving device 120 to drive the opening and closing member to switch between the open position and the closed position, and basically does not affect the powder held in the container body 111. Therefore, in this stroke, the third speed can be set to be greater than the second speed, so that the guide protrusion 123a can be disengaged from the guide groove 114b at a relatively fast speed, thereby improving the overall operating efficiency.

[0473] It should be noted that step G130, which is executed after step G110, and step G130, which is executed after step G120, can be set separately. For example, step G130 can be executed only after step G110, or only after step G120. Of course, the two can also be set together, that is, step G130 needs to be executed after both step G110 and step G120. In this case, the first stroke in the two steps G130 can be set to be the same or different; the third speed in the two steps G130 can be set to be the same or different.

[0474] Furthermore, when step G110 is performed again after step G130 is provided as described above, step G110 includes:

[0475] Step G111: upon receiving the opening instruction, controlling the output shaft to rotate at a fourth speed for the first stroke until the output shaft is connected to the opening and closing member;

[0476] Step G112: Control the output shaft to rotate in the same direction at a first speed to drive the opening and closing member to move to the open position.

[0477] In this embodiment, when the open command is received, guide protrusion 123a is separated from guide groove 114b. Therefore, it is necessary to first connect guide protrusion 123a to guide groove 114b. Based on this, control device 800 controls the output shaft to rotate, driving guide protrusion 123a toward guide groove 114b until it enters guide groove 114b. Once guide protrusion 123a is inserted into guide groove 114b, it can continue to slide along guide groove 114b, driving the opening and closing member to the open position.

[0478] Furthermore, when step G120 is performed again after step G130 is provided as described above, step G120 includes:

[0479] Step G121: upon receiving the closing instruction, controlling the output shaft to rotate at a fourth speed for the first stroke until the output shaft is connected to the opening and closing member;

[0480] Step G122: Control the output shaft to rotate in the same direction at a second speed to drive the opening and closing member to move to the closed position.

[0481] Similarly, when a close command is received, guide protrusion 123a is separated from guide groove 114b, so it is necessary to first connect guide protrusion 123a to guide groove 114b. Based on this, control device 800 controls the output shaft to rotate, driving guide protrusion 123a toward guide groove 114b until it enters guide groove 114b. Once guide protrusion 123a is inserted into guide groove 114b, it can continue to slide along guide groove 114b, driving the opening and closing member to the closed position.

[0482] It should be noted that the first stroke setting in the above-mentioned steps G111 and G121 is equivalent to the above-mentioned step G130 and will not be described in detail. The fourth speed can also be selected to be greater than the second speed. Furthermore, the fourth speed can be set to be the same as the third speed, greater than the third speed, or less than the third speed according to actual needs. Among them, when the fourth speed is greater than the third speed, it helps to quickly connect the guide protrusion 123a and the guide groove 114b to the position, shortening the response time of the opening instruction and the closing instruction. When the fourth speed is less than the third speed, it helps the guide protrusion 123a to dock with the guide groove 114b more smoothly.

[0483] In the above embodiment, the driver 122 can be specifically configured as a motor, and the driver 122 drives the opening and closing member to switch between the open position and the closed position by switching the direction of the motor. In this way, there is no need to achieve reversal by rotating the rotating member 123 in a full circle or providing an additional reversing component, which helps to simplify the structure.

[0484] Based on the above embodiment, the rotation direction of the output shaft is the same as the movement direction of the opening and closing member, which helps to simplify the overall structure of the driving device 120 and avoids multiple reversing transmissions that would reduce efficiency.

[0485] Furthermore, in one embodiment, the control method of the weighing module further includes:

[0486] Step G141: upon receiving the opening instruction or the closing instruction, controlling the position sensor 121b to start operation;

[0487] Step G142: When it is detected that the trigger unit is currently in the corresponding stop position, controlling the driver 122 to start operation;

[0488] Step G143: When it is detected that the trigger unit is not currently in the corresponding stop position, the driver 122 is controlled to reset and then start running.

[0489] In this embodiment, taking the above-mentioned first stop position and second stop position as an example, at this time, the position sensor 121b set at the first stop position is the first position sensor 121b, and the position sensor 121b set at the second stop position is the second position sensor 121b.

[0490] When step G110 is executed and the open command is received, the control device 800 first controls the first position sensor 121b to start operation and, through sensing by the first position sensor 121b, determines whether the trigger portion is currently in the first stop position. If the trigger portion is in the first stop position, it indicates that the drive device 120 is operating normally, and the driver 122 can be directly controlled to start operation, driving the open...
