[0002] Coffee grinders used in home environments are used less frequently and require less coffee grounds compared to commercial grinders. Therefore, users typically need to manually control the amount of coffee beans fed into the grinder.

[0041] In the technical solution provided by this invention, when an operation such as weighing beans is required, the drive mechanism can introduce external beans into the receiving cavity through the feed inlet. This effectively controls the opening and closing of the feed inlet to a certain extent, ensuring that beans are only introduced into the receiving cavity when needed, preventing spoilage due to excessive pre-stored beans. After the beans are introduced into the receiving cavity, the weighing device can weigh them, thus obtaining the actual mass value of the beans in a timely and accurate manner. This weight is then fed back to the drive mechanism, helping it to promptly stop the continued introduction of external beans. Furthermore, the drive mechanism can also discharge the beans from the receiving cavity through the discharge outlet, effectively controlling the opening and closing of the discharge outlet to a certain extent, allowing beans to be discharged as needed.
[0042] The drive mechanism and weighing device in this application work together to precisely control the output of coffee beans each time, thus ensuring a stable and controllable coffee bean feed rate to the grinder. Furthermore, the coffee bean weighing device in this application is integrated into the grinder, meaning it is specifically designed for use with the grinder. The quantitative transfer of coffee beans between the weighing device and the grinder requires minimal user intervention, meaning they are minimally exposed to the external environment. This helps improve the consistency of coffee bean feeding accuracy, reduces contamination of the beans, and ultimately enhances the quality of beverages made from the beans.

[0050] Please see Figures 1 to 10 This invention provides a bean weighing device 200. This bean weighing device 200 can be specifically used for weighing beans. In practical applications, the bean weighing device 200 is mainly assembled into a coffee grinder.
[0051] It is understandable that, in addition to the bean weighing device 200, the coffee grinder also includes the main body 100.
[0052] The main body 100 includes at least a frame 110 and a grinding device 120 disposed on the frame 110. The grinding device 120 includes a grinding container 121 and a grinding assembly 122 that acts within the grinding container 121. The interior of the grinding container 121 forms a grinding chamber. The grinding chamber is provided with a grinding inlet 121a and a grinding outlet 121b. The grinding inlet 121a is used to receive external soybeans, while the grinding outlet 121b is used to discharge the ground powder.
[0053] The grinding assembly 122 is used to grind the soybeans in the grinding chamber to obtain powder of the desired fineness. Therefore, the type of grinding assembly 122 is not limited, and can be, but is not limited to, a cutter head assembly and a power unit that drives the cutter head assembly. The cutter head assembly, for example, specifically includes two cutter heads. A grinding gap is formed between the two cutter heads. When the soybeans in the grinding chamber enter the grinding gap, the power unit drives at least one of the two cutter heads to move relative to the other. The movement can be, for example, by rotating around a fixed axis. In this way, the soybeans in the grinding gap are squeezed and ground during the movement, ultimately obtaining powder.
[0054] Please refer to details. Figures 1 to 2 The rack 110 includes, for example, a base and a stand. The base extends generally horizontally and is used to mount on a platform such as a desktop. The stand is erected vertically on the base.
[0055] The frame can partially or completely define a mounting cavity. Optionally, part or all of the grinding device 120 can be assembled into the mounting cavity. Alternatively, other devices in the main body 100 besides the grinding device 120 can also be selected to be partially or completely assembled into the mounting cavity as needed.
[0056] In a further embodiment, the main body 100 may also include a bean hopper 140. The bean hopper 140 contains a bean storage chamber. Similarly, the bean storage chamber may have a bean inlet and a bean outlet 141. Initially, external beans can enter the bean storage chamber through the bean inlet. The bean storage chamber can pre-store at least two portions of beans as needed. When needed, the beans in the bean storage chamber can be discharged outwards through the bean outlet 141.
[0057] When the main body 100 includes a base and a stand as described above, the bean hopper 140 and the stand can be integrally formed. That is, at least a portion of the stand constitutes the bean hopper 140. At least a portion of the aforementioned mounting cavity constitutes the bean storage cavity.
[0058] Alternatively, the bean hopper 140 and the upright frame can be detachably or non-detachably connected and fixed after being separately formed. Specifically, for example, the aforementioned mounting cavity extends through the top or any side of the upright frame to form an insertion interface. The bean hopper 140 can enter and exit the mounting cavity via the insertion interface, thereby achieving a detachable connection between the bean hopper 140 and the upright frame.
[0059] Generally, the stand is offset to the side of the central axis of the base, so that the base can reserve enough space for placement on the horizontal side of the stand.
[0060] The base has a corresponding space for placing external containers, such as powder bowls for collecting powder.
[0061] The area above the base, corresponding to the mounting space, can accommodate all or part of the aforementioned grinding device 120. This allows for a substantially vertical alignment between at least the grinding outlet 121b of the grinding chamber and the external container, enabling the powder discharged through the grinding outlet 121b to fall into the external container under gravity. Furthermore, the relatively heavy grinding device 120 and the bean hopper 140 are arranged horizontally, helping to stabilize the machine's center of gravity between them.
[0062] Based on the above, then combining Figures 3 to 10 The specific configuration scheme of the main symmetrical bean device 200 will be described.
[0063] The bean weighing device 200 is assembled in the coffee grinder. The bean weighing device 200 includes a receiving part 210, a drive mechanism 220, and a weighing device 230.
[0064] The specific form of the receiving component 210 is not limited; it can be set as a plate, a frame, a container, etc., according to actual needs. For ease of understanding, the following explanation will take the container-shaped structure shown in the figure as an example.
[0065] The receiving component 210 is provided with a receiving cavity 211. The receiving cavity 211 is provided with an inlet 212 and an outlet 213.
[0066] The drive mechanism 220 is used to feed external soybeans into the receiving chamber 211 through the feed inlet 212 and / or to discharge soybeans from the receiving chamber 211 outward through the discharge outlet 213.
[0067] Weighing device 230 is used to weigh the mass of the soybeans fed into the receiving cavity 211.
[0068] In the technical solution provided by the present invention, when it is necessary to perform an operation such as weighing beans, the drive mechanism 220 can introduce external beans into the receiving cavity 211 through the feed port 212, that is, to a certain extent, the opening and closing control of the feed port 212 is realized, so that the beans are only introduced into the receiving part 210 when needed, and the beans are prevented from deteriorating due to excessive pre-storage.
[0069] Once the soybeans are fed into the receiving cavity 211, the weighing device 230 can weigh the soybeans, thus obtaining the actual mass value of the soybeans in a timely and accurate manner. This mass value is then fed back to the drive mechanism 220, which helps the drive mechanism 220 to stop the continued feeding of external soybeans in a timely manner.
[0070] Furthermore, the drive mechanism 220 can also discharge the soybeans in the receiving chamber 211 outward through the discharge port 213, which means that the opening and closing control of the discharge port 213 is realized to a certain extent, so that the soybeans can be discharged as needed.
[0071] The combination of the drive mechanism 220 and the weighing device 230 in this application can accurately control the output of beans each time, thereby making the bean feed of the grinder stable and controllable.
[0072] Furthermore, the bean weighing device 200 of this application is mounted on a coffee grinder. This means the bean weighing device 200 is specifically designed for coffee grinders. The quantitative transfer of beans between the bean weighing device 200 and the coffee grinder requires virtually no user intervention, meaning it is minimally exposed to the external environment. This helps improve the consistency of bean feeding accuracy and reduces bean contamination, ultimately contributing to improved quality of beverages made from beans.
[0073] It can be understood that the bean weighing device 200 is generally located upstream of the grinding inlet 121a and is used to weigh the mass of the beans entering the grinding inlet 121a. The upstream side refers to any time and space before the beans enter the grinding inlet 121a.
[0074] It is understandable that there are no restrictions on the specific form in which the bean weighing device 200 is assembled into the main body 100: For example, in one configuration, at least a portion of the bean weighing device 200 may be external to the main unit 100. That is, at least a portion of the bean weighing device 200 is exposed outside the main unit 100, and can be visually viewed by the user, or can be used by the user to perform the required and corresponding operations.
[0075] At this time, the weighing device 200 can remain connected to the main body 100. For example, the weighing device 200 can be directly or indirectly mounted on a stand. The weighing device 200 and the main body 100 are pre-integrated as a whole, allowing for transfer and storage as a whole.
[0076] Alternatively, the bean weighing device 200 can be installed independently of the main body 100. For example, the bean weighing device 200 and the main body 100 can be kept separate. The bean weighing device 200 can be placed near the main body 100 by default or as recommended. Alternatively, the bean weighing device 200 can be installed at any position on the main body 100 to suit the actual installation environment, making the overall application of the coffee grinder more flexible and compatible.
[0077] When the bean weighing device 200 is assembled to the main body 100, the bean weighing device 200 and the main body 100 can be directly connected. For example, at least a portion of the bean weighing device 200 is directly embedded in the main body 100. Alternatively, the bean weighing device 200 can be directly and fixedly or movably assembled to the outer wall of the main body 100.
[0078] Alternatively, the bean weighing device 200 can be indirectly connected to the main body 100. For example, the bean weighing device 200 can be assembled to the inside or outside of the main body 100 via additional fittings. Alternatively, the bean weighing device 200 can be assembled to the inside or outside of the main body 100 via other modules fixed in the grinder. These other modules can be the grinding device 120 as described above, or the bean hopper 140, or any other suitable module structure.
[0079] Alternatively, in another configuration, the bean weighing device 200 can be integrated into the main body 100. That is, the bean weighing device 200 is essentially not visible. This contributes to a cleaner and more aesthetically pleasing overall design of the coffee grinder. It also helps to protect the bean weighing device 200 using the grinder's frame 110, such as part of the outer casing structure. Specifically, it can protect components within the bean weighing device 200, such as the weighing device 230 and the feed inlet 212 in the receiving part 210, preventing external environmental contamination or impurities from interfering with the weighing process.
[0080] Furthermore, after the bean weighing device 200 is assembled to the main body 100, in one embodiment, the bean weighing device 200 can be fixed in position relative to the grinding container 121. That is, the bean weighing device 200 is fixedly assembled to the main body 100.
[0081] Optionally, the receiving part 210 of the bean weighing device 200 may be integrally formed with the grinding container 121 and the stand in the main body 100. Alternatively, the two may be formed separately and then connected and fixed in a detachable or non-detachable manner.
[0082] Alternatively, in another embodiment, the orientation of the bean weighing device 200 relative to the grinding container 121 can be adjusted. That is, after the bean weighing device 200 is assembled into the main body 100, its orientation and / or position can be adjusted when needed, such as when product debugging is required or when different positions of the grinding device 120 need to be matched, so that the orientation of the bean weighing device 200 is more accurate and practical.
[0083] The orientation adjustment of the bean weighing device 200 can be, but is not limited to, vertical height adjustment, horizontal distance adjustment from the grinding device 120, etc. Alternatively, it can be adjusting the orientation of the receiving cavity 211, the feed inlet 212 and / or the discharge outlet 213, etc.
[0084] In the specific assembly scheme of the bean weighing device 200, for example, when the main body 100 is not equipped with a bean hopper 140, the bean weighing device 200 can be directly assembled on the stand, and the discharge port 213 of the receiving part 210 and the grinding inlet 121a of the grinding container 121 are correspondingly set.
[0085] A bean drop channel is formed between the discharge port 213 of the receiving component 210 and the grinding inlet 121a of the grinding container 121. This bean drop channel can be controlled to open or close. When open, the beans in the receiving component 210 can enter the grinding container 121.
[0086] Specifically, the bean flow channel can achieve flexible switching between the conduction state and the blocking state by, for example, moving the opening and closing parts set at the discharge port 213 and / or the grinding inlet 121a, or the valve body set at the pipeline between the discharge port 213 and the grinding inlet 121a.
[0087] And / or, when the bean weighing device 200 includes a drive mechanism 220 as described above, and especially when the drive mechanism 220 is configured to discharge the beans in the receiving chamber 211 outward through the discharge port 213, the drive mechanism 220 can also be used to control the opening or blocking of at least a partial section of the bean dropping channel. For example, controlling the opening or blocking of the discharge port 213 located in the receiving chamber 211 or the section of the channel adjacent to the discharge port 213 in the bean dropping channel.
[0088] Furthermore, when the main body 100 is provided with a bean hopper 140 as described above, the receiving component 210 and the bean hopper 140 may optionally be integrated. For example, the receiving component 210 may directly constitute the bean hopper 140.
[0089] Alternatively, the receiving component 210 and the bean hopper 140 can be installed separately. Then, the receiving component 210 and the bean hopper 140 can be connected in a detachable or non-detachable manner.
[0090] Since the receiving component 210 and the bean hopper 140 are separate components, the receiving component 210 is generally located between the bean hopper 140 and the grinding container 121. Similar to the bean drop channel described above, a bean inlet channel is formed between the receiving component 210 and the bean hopper 140. The bean inlet channel can be controlled to open or close. When open, the beans in the bean hopper 140 can enter the receiving component 210.
[0091] Specifically, the bean inlet channel can be flexibly switched between the open and closed states by, for example, moving the opening and closing parts provided at the bean outlet 141 and / or the inlet 212 of the bean hopper 140, or the valve body provided at the pipe between the bean outlet 141 and the inlet 212.
[0092] And / or, when the bean weighing device 200 includes a drive mechanism 220 as described above, especially when the drive mechanism 220 is configured to feed external beans into the receiving cavity 211 via the feed inlet 212, the drive mechanism 220 can also be used to control the opening or closing of at least a partial section of the bean feed channel. For example, controlling the opening or closing of the feed inlet 212 located in the receiving cavity 211 or the section of the channel adjacent to the feed inlet 212 in the bean feed channel.
[0093] Of course, when the receiving part 210 and the bean hopper 140 are separate, similarly to the above, the receiving part 210 can be built into the bean hopper 140. Alternatively, the receiving part 210 can also be at least partially externally placed in the bean hopper 140.
[0094] Furthermore, based on the above, once the bean weighing device 200 is assembled in place at the main body 100, a direct connection can be made between, for example, the discharge port 213 and the grinding inlet 121a. For example, the discharge port 213 and the grinding inlet 121a can be directly aligned.
[0095] Alternatively, in one specific design, the grinder may also include a connecting pipe 130. The outlet 213 is connected to the grinding inlet 121a via the connecting pipe 130. In this case, the specific orientations of the weighing device 200 and the grinding device 120 are not restricted. As long as the shape, size, and other structural parameters of the connecting pipe 130 are designed appropriately, it can be directly adapted to connect the outlet 213 and the grinding inlet 121a.
[0096] The specific orientations of the discharge port 213 and the grinding inlet 121a are not restricted. Generally, to make good use of gravity, the discharge port 213 can be located above the grinding inlet 121a. For example, the discharge port 213 can be located vertically above the grinding inlet 121a. In this case, when the aforementioned connecting pipe 130 is provided, the connecting pipe 130 extends essentially vertically. Alternatively, for example, the discharge port 213 can be located diagonally above the grinding inlet 121a. In this case, when the aforementioned connecting pipe 130 is provided, the connecting pipe 130 can extend at an angle, forming an inclined guide channel.
[0097] Generally, a coffee grinder can be equipped with one bean hopper 140. Alternatively, depending on actual needs, the coffee grinder may have at least two bean hoppers 140. When there are at least two bean hoppers 140, each bean hopper 140 can be used to store the same type of coffee beans, serving as a backup for each other. Alternatively, at least two of the bean hoppers 140 can be used to store different types of coffee beans, allowing users to choose according to their needs.
[0098] When at least two bean hoppers 140 are provided, in order for the same bean weighing device 200 to be adapted to weigh the bean material discharged from each bean hopper 140, optionally, at least one of the receiving member 210 and each bean hopper 140 is movable relative to the other, so that during its movement, the bean weighing device 200 can weigh the mass value of the bean material discharged from each bean hopper 140 respectively.
[0099] For example, the orientation of each bean bin 140 within the main body 100 remains essentially fixed. At this time, at least the receiving component 210 of the bean weighing device 200 can reciprocate between each bean bin 140, causing the feed inlet 212 to pass sequentially through the bean outlet 141 of each bean bin 140, thereby receiving the bean material discharged outward through each bean outlet 141.
[0100] Or, for example, the orientation of at least the receiving member 210 of the bean weighing device 200 remains basically fixed. At this time, each bean bin 140 can pass through the receiving member 210 in sequence, causing the bean outlet 141 of each bean bin 140 to pass through the inlet 212 in sequence, so that the bean material discharged from each bean outlet 141 can be put into the inlet 212.
[0101] As can be seen from the above, the weighing device 230 is mainly used to weigh the soybeans entering the receiving cavity 211.
[0102] In a specific configuration, the weighing device 230 can directly weigh the soybeans. For example, the weighing device 230 is built into the receiving cavity 211 and is configured to receive all the soybeans entering the receiving cavity 211. After receiving, the mass of the received soybeans can be weighed. The weighing device 230 can directly form a partition structure within the receiving cavity 211 or a cover structure provided at the discharge port 213. Alternatively, the weighing device 230 can be equipped with, for example, a stress sensor at the aforementioned partition structure and / or cover structure.
[0103] First, it should be clarified that the distinction between contact and non-contact connections discussed below primarily refers to whether or not an external force affecting the weighing weight of the beans is applied to the weighing device 230. In other words, a non-contact connection refers to a connection that does not contact the weighing device 230, thus essentially not applying any external force affecting its weight. Conversely, a contact connection refers to a connection that is in contact with the weighing device 230, and at the point of contact, an external force affecting its weight is applied to the weighing device 230.
[0104] Based on this, in another specific configuration, the weighing device 230 is at least in contact with the receiving member 210. Simultaneously, the drive mechanism 220 is in a non-contact connection with the receiving member 210. That is, the drive mechanism 220 essentially does not apply gravity to the receiving member 210. In this case, the weighing device 230 is configured to weigh the receiving member 210 at least after the receiving cavity 211 has received the beans.
[0105] Since the mass value of the receiving component 210 itself (hereinafter referred to as the container mass value for ease of understanding) remains essentially constant: when no external bean material is connected, if the weighing device 230 is activated and weighs, the mass value of the container will be measured. When external bean material is connected, the weighing device 230 is activated and weighs, and the mass value of both the container and the bean material will be measured. Therefore, the mass value of the bean material can be calculated.
[0106] Alternatively, in another specific configuration, the weighing device 230 is at least in contact with the receiving member 210. Simultaneously, the drive mechanism 220 is also in contact with the receiving member 210. That is, the drive mechanism 220 applies gravity to the receiving member 210. In this case, the weighing device 230 is configured to weigh the total mass of the receiving member 210 and the drive mechanism 220, at least after the beans are introduced into the receiving cavity 211.
[0107] Similarly, since the container mass of the receiving component 210 and the mass of the driving mechanism 220 (hereinafter referred to as the driving mass value for ease of understanding) remain essentially constant: when no external bean material is connected, if the weighing device 230 starts and weighs, the weight being measured is the sum of the container mass value and the driving mass value. When external bean material is connected, if the weighing device 230 starts and weighs, the weight being measured is the sum of the container mass value, the driving mass value, and the bean material mass value. Therefore, the bean material mass value can be calculated.
[0108] It is understandable that in practical applications, the weighing device 230 can weigh the aforementioned receiving component 210, or the receiving component 210 and the drive mechanism 220 as a whole, simply after the soybeans are inserted into the receiving cavity 211, and then calculate the mass value of the soybeans. At this time, it is assumed that the aforementioned container mass value and drive mass value are basically stable and unchanged.
[0109] Alternatively, the weighing device 230 can weigh the receiving component 210, or the entire receiving component 210 and drive mechanism 220, not only after the beans are introduced into the receiving cavity 211, but also before the beans are introduced into the receiving component 210, and before that, the entire receiving component 210 and drive mechanism 220 are introduced into the receiving component 210. The weight of the beans is then calculated. In this case, the weight of the container and the drive mechanism are calibrated each time or at a set period, which helps to promptly detect abnormalities such as residue in the receiving component 210 or structural damage to the drive mechanism 220, resulting in a more accurate final weight of the beans.
[0110] There are several solutions for the drive mechanism 220 to achieve the above objectives: For example, the drive mechanism 220 can be configured as a pneumatic drive device. The pneumatic drive device can create negative pressure in the receiving cavity 211 and / or positive pressure in the bean hopper 140 to push the beans in the bean hopper 140 into the receiving cavity 211. And / or, the pneumatic drive device can create positive pressure in the receiving cavity 211 and / or negative pressure in the grinding cavity to push the beans in the receiving cavity 211 into the grinding cavity.
[0111] Or such as Figures 3 to 10 As shown, the drive mechanism 220 includes a cover and a drive assembly 222. The cover is movably disposed on the receiving member 210. During the movement of the cover, the inlet 212 and / or outlet 213 at its location can be opened or closed. The drive assembly 222 is drively connected to the cover.
[0112] The cover can be movably disposed at the inlet 212 and / or outlet 213, for example, disposed inside or outside the inlet 212 and / or outlet 213, directly acting on the inlet 212 and / or outlet 213. Alternatively, the cover can be movably disposed within the receiving cavity 211, and then indirectly act on the inlet 212 and / or outlet 213.
[0113] In practical applications, two covers can be provided. The two covers are a feed cover 221a that is movably disposed at the feed inlet 212 and a discharge cover 221b that is movably disposed at the discharge outlet 213. That is, under the drive of the drive component 222, the feed cover 221a can open or close the feed inlet 212; the discharge cover 221b can open or close the discharge outlet 213.
[0114] At this time, driven by the drive component 222, the movement of the feed cover 221a and the movement of the discharge cover 221b are independently configured. Specifically, for example, there are two drive components 222. One of the two drive components 222 drives the movement of the feed cover 221a, and the other drives the movement of the discharge cover 221b. Moreover, the two drive components 222 are structurally complete and functionally independent, and they basically do not affect each other.
[0115] Alternatively, the movement of the feed cover 221a and the movement of the discharge cover 221b can be configured in a mutually related manner. This relationship can be reflected in the timing, stroke, and frequency of movement of the feed cover 221a and the discharge cover 221b.
[0116] Correspondingly, two drive components 222 can be configured. One of the two drive components 222 drives the feed cover 221a to move, while the other drives the discharge cover 221b to move. However, the two drive components 222 can be configured in a coordinated manner in terms of structure or function.
[0117] Alternatively, a single drive component 222 can be configured. This drive component 222 synchronously drives the feed cover 221a to move and the discharge cover 221b to move.
[0118] Considering the actual application requirements of the bean weighing device 200 in the main body 100, specifically, under the drive of the drive component 222, one of the feed cover 221a and the discharge cover 221b can be sealed to the corresponding feed port 212 or discharge port 213, while the other can be opened to the corresponding feed port 212 or discharge port 213.
[0119] That is, before or at the same time as the feed inlet 212 is opened by the feed cover 221a, the discharge outlet 213 can be sealed by the discharge cover 221b. This allows the receiving cavity 211 to better receive and temporarily store external soybeans in real time, and allows enough time for the weighing device 230 to weigh them.
[0120] Furthermore, at the same time or after the feed inlet 212 is sealed by the feed cover 221a, the discharge outlet 213 can be opened by the discharge cover 221b. This allows the soybeans that have been received and weighed in the receiving cavity 211 to be discharged quantitatively, preventing soybeans from continuing to enter the feed inlet 212 and increasing weighing errors.
[0121] The weighing device 230 and the drive assembly 222 can be configured together. Specifically, for example, but not limited to, the grinder also includes a control device. The control device is electrically connected to both the weighing device 230 and the drive assembly 222.
[0122] At this time, when the control device senses that the drive assembly 222 drives the discharge cover 221b to seal the discharge port 213 and the feed cover 221a to open the feed port 212, it indicates that external beans have been introduced into the receiving cavity 211. The external beans are temporarily sealed inside the receiving cavity 211 by the discharge cover 221b. At this point, it is highly likely that a bean weighing operation will be performed. The control device can then control the weighing device 230 to start operation and weigh the receiving component 210 or the entire receiving component 210 and drive mechanism 220 according to a preset mass value.
[0123] Alternatively, when the control device senses that the mass value weighed by the weighing device 230 has reached a preset mass threshold, the control device can control the drive assembly 222 to drive the feed cover 221a to seal the feed port 212. That is, to ensure that the receiving cavity 211 stops receiving external soybeans, thus preventing the weighing device 230 from weighing too many soybeans.
[0124] In another embodiment, optionally, after sensing that the drive assembly 222 drives the discharge cover 221b to open the discharge port 213 and the feed cover 221a to open the feed port 212, the control device may assume that the current receiving cavity 211 is equivalent to a through-passage transition pipe, serving the purpose of transitioning the soybeans to the grinding cavity. At this time, the control device can control the weighing device 230 to remain off, or start operation but not perform the weighing function.
[0125] To enable the cover to open and close the corresponding inlet 212 or outlet 213 during its movement: Specifically, the cover body is translatably disposed relative to the receiving member 210, so that the corresponding feed port 212 or discharge port 213 can be opened or closed during its translation. For example, the translation direction of the feed cover body 221a can be along the plane of the feed port 212, or along the central axis of the feed port 212. Similarly, the translation direction of the discharge cover body 221b can be along the plane of the discharge port 213, or along the central axis of the discharge port 213.
[0126] And / or specifically, the cover is rotatably disposed relative to the receiving member 210 so that it can open or close the corresponding feed port 212 or discharge port 213 during its rotation. In this case, for example, the axis of rotation of the feed cover 221a can be any axis on the plane containing the feed port 212, or an axis outside the plane containing the feed port 212 that is parallel to or intersects it. Similarly, for example, the axis of rotation of the discharge cover 221b can be any axis on the plane containing the discharge port 213, or an axis outside the plane containing the discharge port 213 that is parallel to or intersects it.
[0127] Of course, the cover can be formed by a single structure. Alternatively, the cover can include at least two plates. At least one of the plates is movable such that the plates can jointly open or close the corresponding inlet 212 or outlet 213.
[0128] Specifically, the plates in the feed cover 221a are arranged sequentially along the plane of the feed inlet 212, and together they seal the feed inlet 212 after they approach each other. Alternatively, the feed inlet 212 opens together after the plates move away from each other. Similarly, the plates in the discharge cover 221b are arranged sequentially along the plane of the discharge outlet 213, and together they seal the discharge outlet 213 after they approach each other. Alternatively, the discharge outlet 213 opens together after the plates move away from each other.
[0129] Alternatively, the plates in the feed cover 221a may be arranged sequentially along the central axis of the feed inlet 212, and stacked together to seal the feed inlet 212 after the plates approach each other. Conversely, the feed inlet 212 may open together after the plates move away from each other. Similarly, the plates in the discharge cover 221b may be arranged sequentially along the central axis of the discharge outlet 213, and stacked together to seal the discharge outlet 213 after the plates approach each other. Conversely, the discharge outlet 213 may open together after the plates move away from each other.
[0130] In the above embodiments, specifically, at least one plate may be provided with a through hole along its thickness direction. Then, during the relative translation and / or relative rotation of the plates, the remaining at least one plate may be moved to open or close the through hole.
[0131] Of course, the movement scheme of the plate can refer to the above, and can be translated and / or rotated.
[0132] Furthermore, based on one or more of the above embodiments, the drive mechanism 220 further includes a pusher 223. The pusher 223 is movably disposed relative to the receiving member 210, and simultaneously or subsequently, when the drive assembly 222 drives the cover to open the discharge port 213, the pusher 223 pushes the soybeans in the receiving cavity 211 outward through the discharge port 213. By providing the pusher 223, the soybean weighing device 200 can be freed from dependence on gravity, or, in conjunction with gravity, better discharge the soybeans in the receiving cavity 211 outward through the discharge port 213.
[0133] There are several specific designs for pusher component 223: For example, in one specific embodiment, the feed cover 221a and / or the discharge cover 221b constitute a pusher 223. For example, when the discharge cover 221b opens the discharge port 213, the feed cover 221a moves horizontally toward the discharge port 213, which is equivalent to a piston structure. This can both keep the feed port 212 sealed and push the soybeans in the receiving cavity 211 outward through the discharge port 213.
[0134] Alternatively, for example, the discharge port 213 is located at the vertical bottom of the receiving cavity 211. The discharge cover 221b is correspondingly located vertically below the receiving member 210. Thus, when the discharge cover 221b seals the discharge port 213, and the inlet 212 is opened to receive external beans, the beans can accumulate at the discharge cover 221b, i.e., be received by the discharge cover 221b. At this time, while the drive assembly 222 drives the discharge cover 221b to open the discharge port 213, the specific action of the discharge cover 221b can achieve the purpose of driving the received beans outward through the discharge port 213. In other words, the discharge cover 221b constitutes a pusher 223.
[0135] Specifically, in one embodiment, the discharge cover 221b is rotatable. When rotated to an angle relative to the plane of the discharge port 213, the discharge cover 221b forms an inclined surface. The soybeans collected on this inclined surface can slide outwards along the inclination, ensuring that all the soybeans weighed within the receiving chambers 211 can be pushed out.
[0136] Alternatively, in one embodiment, the pusher 223 is positioned adjacent to the discharge port 213 and extends toward the discharge cover 221b. The discharge cover 221b is translatably positioned and can move past the pusher 223, so that during the translation of the discharge cover 221b, the pusher 223 can push the soybeans received by the discharge cover 221b in the opposite direction.
[0137] The extension direction of the pusher 223 intersects with the translation direction of the discharge cover 221b. Specifically, the pusher 223 can extend to directly abut against the surface of the discharge cover 221b that receives the soybeans. Thus, when the discharge cover 221b translates, it slides along the surface of the discharge cover 221b that receives the soybeans, pushing the soybeans out. Alternatively, the pusher 223 can extend to maintain a certain gap with the surface of the discharge cover 221b that receives the soybeans. However, this gap is generally set to be no larger than the particle size of the soybeans. In this way, the soybeans received by the discharge cover 221b can also be pushed out when the discharge cover 221b translates.
[0138] The pusher 223 mentioned above can be integrally formed with the receiving component 210. For example... Figures 3 to 10 As shown, it is directly defined by a portion of the shell wall of the receiving member 210. At this time, the orientation of the pusher member 223 relative to the receiving member 210 remains essentially fixed.
[0139] Alternatively, after the pusher 223 and the receiver 210 are separately formed, they can be detachably or non-detachably connected. In this case, the orientation of the pusher 223 relative to the receiver 210 can be set to be fixed. Or, according to actual needs, the orientation of the pusher 223 relative to the receiver 210 can also be adjusted. And during its adjustment, at least the distance between the pusher 223 and the discharge cover 221b should be different, or the effective plate area of the pusher 223 acting on the pusher should be different, or the actual position of the pusher 223 acting on the pusher should be different, etc. There are no restrictions.
[0140] Alternatively, when the pusher 223 is at least partially exposed on the outside of the receiver 210, the exposed portion of the pusher 223 can be structurally modified so that the exposed portion can be adapted for installation of the weighing device 230. This allows the pusher 223 to be reused to achieve a stable assembly of the weighing device 230.
[0141] Please refer to the specific details. Figures 5 to 10 In practical applications, there are two covers. The two covers are a feed cover 221a that can be moved along the plane of the feed inlet 212 and a discharge cover 221b that can be moved along the plane of the discharge outlet 213.
[0142] Optionally, the planes where the inlet 212 and the outlet 213 are located are parallel or nearly parallel, so that the translation direction of the inlet cover 221a and the translation direction of the outlet cover 221b are basically in the same or opposite directions, thus making the setting in the translation space more reasonable and making the overall structure of the receiving part 210 more regular and beautiful.
[0143] And / or the feed cover 221a is exposed on the outside of the feed inlet 212. And / or the discharge cover 221b is exposed on the outside of the discharge outlet 213. In this way, the feed cover 221a and / or the discharge cover 221b do not occupy additional space in the receiving cavity 211, and make the disassembly, replacement and maintenance of the feed cover 221a and / or the discharge cover 221b more intuitive and convenient.
[0144] Furthermore, one of the cover and the receiving component 210 is provided with a guide protrusion 214, and the other is provided with a guide groove. The guide protrusion 214 and / or the guide groove are adapted to extend the translational trajectory of the cover. During the translation of the cover, the guide protrusion 214 moves within the guide groove. In this way, based on the mutual guiding cooperation of the guide protrusion 214 and the guide groove, the translational trajectory of the feed cover 221a and / or the discharge cover 221b is more accurate and the translational process is more stable.
[0145] Specifically, such as Figures 3 to 6 As shown, in the first embodiment of the drive assembly 222, the drive assembly 222 includes a first gear set 222a, a second gear set 222b, and a gear 222c.
[0146] The first gear assembly 222a is located on the feed cover 221a near the discharge cover 221b. That is, all teeth in the first gear assembly 222a face the discharge cover 221b. In this case, the first gear assembly 222a and the feed cover 221a can be integrally formed. Alternatively, the first gear assembly 222a and the feed cover 221a can be separately formed and then connected in a detachable or non-detachable manner.
[0147] The second gear assembly 222b is located on the discharge cover 221b near the inlet cover 221a. That is, all teeth in the second gear assembly 222b face the inlet cover 221a. In this case, the second gear assembly 222b and the discharge cover 221b can be integrally formed. Alternatively, the second gear assembly 222b and the discharge cover 221b can be separately formed and then connected in a detachable or non-detachable manner.
[0148] Gear 222c is rotatably disposed between the first gear set 222a and the second gear set 222b, and meshes with both gear sets 222a and 222b respectively. The axis of rotation of gear 222c can be a fixed axis. For example, gear 222c is rotatably mounted on the receiving member 210 via a fixed shaft. Alternatively, depending on actual needs, the axis of rotation of gear 222c can be a movable axis. For example, gear 222c is rotatably mounted on the receiving member 210 via a movably disposed shaft.
[0149] At this point, driven by an external force, gear 222c rotates actively, and either the feed cover 221a or the discharge cover 221b moves actively, causing the feed cover 221a and the discharge cover 221b to move in opposite directions. The external force can be applied manually by the user, or it can be applied automatically by additional settings such as a motor or other driver.
[0150] Or specifically, such as Figures 7 to 10 As shown, in the second embodiment of the drive assembly 222, the drive assembly 222 includes a first pivot shaft 222d, a second pivot shaft 222e, and a swing member 222f.
[0151] The first pivot shaft 222d is disposed corresponding to the feed cover 221a. The second pivot shaft 222e is disposed corresponding to the discharge cover 221b. One of the swing member 222f and the feed cover 221a is fixedly connected to the first pivot shaft 222d, and the other is rotatably connected to the first pivot shaft 222d. One of the swing member 222f and the discharge cover 221b is fixedly connected to the second pivot shaft 222e, and the other is rotatably connected to the second pivot shaft 222e.
[0152] Specifically, for example, the first pivot shaft 222d is fixedly disposed on the side of the feed cover 221a near the weighing device 230. Similarly, the second pivot shaft 222e is fixedly disposed on the side of the discharge cover 221b near the weighing device 230. Then, the swing member 222f is rotatably connected to the first pivot shaft 222d and the second pivot shaft 222e respectively. Thus, when the swing member 222f swings, that is, rotates around the moving axis, the feed cover 221a and the discharge cover 221b are moved in tandem.
[0153] Furthermore, the rotational connection positions between the swing member 222f and the first pivot shaft 222d, and between the swing member 222f and the second pivot shaft 222e, can be movable, for example... Figures 7 to 10 As shown, the swing member 222f has guide grooves corresponding to the first pivot shaft 222d and the second pivot shaft 222e, respectively. The first pivot shaft 222d can move within its guide groove, and the second pivot shaft 222e can move within its guide groove, thereby making the swing of the swing member 222f smoother and more adaptable.
[0154] Driven by an external force, the oscillating component 222f actively oscillates, and the feed cover 221a or the discharge cover 221b actively translates, thereby causing the feed cover 221a and the discharge cover 221b to translate in opposite directions. Similarly, the external force can be applied manually by the user, or it can be applied automatically by additional settings such as a motor or other driver.
[0155] Furthermore, the specific structure of the receiving member 210 is not limited. For example, the volume of at least a portion of the receiving cavity 211 gradually increases from the inlet 212 to the outlet 213. For example, when the direction from the inlet 212 to the outlet 213 is from top to bottom, at least a portion of the receiving cavity 211 takes the shape of a frustum-shaped cone, smaller at the top and larger at the bottom. In this way, the soybeans entering the receiving cavity 211 can fall more evenly and dispersedly at the outlet cover 221b.
[0156] Furthermore, to achieve its control purpose, the aforementioned control device may specifically include: a processor, such as a central processing unit (CPU), a communication bus, a user interface, a network interface, and memory. The communication bus is used to establish communication between these components. The user interface may include a display screen, an input unit such as a keyboard, and optionally, a standard wired or wireless interface. The network interface may optionally include a standard wired or wireless interface (such as a Wi-Fi interface). The memory may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Alternatively, the memory may be a storage device independent of the aforementioned processor.
[0157] Those skilled in the art will understand that the above-described structure does not constitute a limitation on the control device, and may include more or fewer components, or combine certain components, or have different component arrangements.
[0158] The memory, as a storage medium, can include an operating system, a network communication module, a user interface module, and the control program for the coffee grinder.
[0159] In the aforementioned control device, the network interface is mainly used for data communication with the network server; the user interface is mainly used for data interaction with the user; the processor and memory in the control device of the present invention can be set in the coffee grinder, and the control device calls the control program of the coffee grinder stored in the memory through the processor and executes the control method of the coffee grinder provided in the embodiments of the present invention.
[0160] Next, the present invention also provides a control method for a coffee grinder.
[0161] In the first embodiment, the coffee grinder may include at least the coffee weighing device 200 as described above. In this case, the control method for the coffee weighing device 200 includes: Step A100: In response to the weighing instruction, control the drive mechanism 220 to feed the external beans into the receiving chamber 211 through the feed inlet 212.
[0162] Step A200: Control the weighing device 230 to start operation and weigh, and obtain the actual mass value of the soybean material received in the receiving cavity 211.
[0163] Step A300: After the actual quality value reaches the preset quality threshold, the control drive mechanism 220 discharges the soybean material in the receiving chamber 211 out through the discharge port 213.
[0164] In this embodiment, when the weighing command is triggered, the entire machine will automatically respond and run the preset related steps.
[0165] It is understandable that the "weighing beans" command is set to be triggered in any reasonable form, such as, but not limited to: The system utilizes an external input device on the coffee grinder, allowing users to actively input commands as needed. This input device can be a dedicated mechanical button, or it can be a pre-installed interface within the machine's control panel. Optionally, the input device can be a fixed component specifically designed for the coffee grinder, permanently mounted on its exterior. Alternatively, it can be a mobile terminal that is wired or wirelessly connected to the grinder and can be separated from it.
[0166] Of course, the bean weighing command can also be associated with other preset commands and other working modes. For example, when the coffee grinder's preset grinding command is triggered, the bean weighing command can be associated with it. Or, for example, when the coffee grinder is used in combination with another device, such as a brewing machine, if the brewing machine is triggered to run a beverage preparation mode, the bean weighing command can be associated with it.
[0167] When the weighing command is triggered, the drive mechanism 220 first needs to feed the external beans into the receiving cavity 211 through the feed port 212. This will allow the beans to enter the weighing range of the weighing device 230.
[0168] Next, the weighing device 230 starts and runs the weighing function. The weighing device 230 can weigh the beans in real time during the dynamic process of the external beans gradually entering the receiving cavity 211, and obtain the actual mass value of the beans that gradually increases until the actual mass value is close to or basically reaches the preset mass threshold.
[0169] Of course, the weighing device 230 can also perform phased weighing of the external soybeans gradually entering the receiving cavity 211 according to a preset weighing cycle. For example, the time required for the soybeans to reach a preset quality threshold can be estimated in advance as the first time period. Then the first time period can be divided into, for example, the early period and the later period.
[0170] The weighing device 230 can operate at a lower frequency in the first time period, or even without weighing. Conversely, the weighing device 230 can operate at a higher frequency in the second time period, even reaching a real-time weighing frequency. Optionally, the duration of the first time period can be set to be no less than the duration of the second time period. This allows for an appropriate reduction in the operating time and frequency of the weighing device 230 throughout the entire weighing process.
[0171] It can then be understood that there are no restrictions on how the preset quality threshold is determined. It can be, but is not limited to, default values stored in the program beforehand, suggested values obtained in advance and matched with the current bean type, or preference values entered by the user that match their personal preferences.
[0172] Once the weighing device 230 confirms that the actual mass value of the external soybean material currently connected to the receiving cavity 211 has reached the preset mass threshold, the drive mechanism 220 then controls the weighed soybean material in the receiving cavity 211 to be discharged outward through the discharge port 213.
[0173] Before, simultaneously with, or after the soybeans in the receiving chamber 211 are discharged out through the discharge port 213, the procedure also includes: controlling the drive mechanism 220 to stop the external soybeans from continuing to enter the receiving chamber 211 through the feed port 212.
[0174] It is understandable that, due to the different specific structures of the receiving component 210 and the receiving cavity 211, for example, when the weighing device 230 is configured to weigh only the beans, rather than weighing the receiving component 210 and / or the drive mechanism 220 as a whole, two solutions may be formed: Firstly, it lacks a pre-storage function. Essentially, the drive mechanism 220 causes all the soybeans in the receiving chamber 211 to be discharged through the outlet 213, including the previous batch of soybeans that has already been weighed (i.e., reached the preset quality threshold) and the subsequent batches of soybeans that continue to enter the receiving chamber 211 through the inlet 212. Therefore, before or simultaneously with the step of the drive mechanism 220 driving the soybeans in the receiving chamber 211 to be discharged through the outlet 213, the drive mechanism 220 must first be controlled to stop driving external soybeans into the receiving chamber 211 through the inlet 212.
[0175] Secondly, it has a pre-storage function. That is, the drive mechanism 220 will selectively discharge the previous batch of soybeans that has been weighed (i.e., has reached the preset mass threshold) through the discharge port 213. At the same time or before this, the subsequent batches of soybeans that continue to enter the receiving chamber 211 through the feed port 212 will not be discharged. In this case, it is possible to selectively control the drive mechanism 220 to stop driving the external soybeans into the receiving chamber 211 through the feed port 212 before, at the same time, or after the step of the drive mechanism 220 driving the soybeans in the receiving chamber 211 to be discharged through the discharge port 213. Alternatively, the drive mechanism 220 can be controlled to keep the external soybeans continuously entering the receiving chamber 211 through the feed port 212.
[0176] There are several ways to implement this pre-storage function. For example, but not limited to, dividing the receiving cavity 211 into at least two chambers: a feeding chamber connected to the feeding port 212 and a discharging chamber connected to the discharging port 213. The weighing device 230 mainly functions in the discharging chamber. Furthermore, the feeding chamber and the discharging chamber can be controlled to be connected or disconnected.
[0177] For example, the inlet 212 and outlet 213 are not arranged vertically sequentially. Their central axes form a certain angle. This allows the soybeans to be fed in smoothly by gravity when the central axis of the inlet 212 extends vertically. However, since the central axis of the outlet 213 is at an angle to the vertical, it cannot automatically discharge the soybeans outwards entirely by gravity. Conversely, when the central axis of the outlet 213 extends vertically, the soybeans can be discharged outwards smoothly by gravity. However, since the central axis of the inlet 212 is at an angle to the vertical, it cannot automatically feed the soybeans in smoothly by gravity. Or, it cannot directly guide the soybeans fed into the receiving cavity 211 to the outlet 213 by gravity. And so on.
[0178] Of course, the drawings and other examples in this application mainly show that the receiving part 210 does not have the above-mentioned pre-storage function.
[0179] When the grinding assembly 122 is provided as described above, similarly, before, at the same time or after the soybean material in the receiving cavity 211 is discharged out through the discharge port 213, the step of controlling the grinding assembly 122 to start operation is also included to grind the soybean material that enters the grinding inlet 121a through the discharge port 213 to obtain powder.
[0180] It is understandable that after the weighed soybeans (i.e., those that have reached the preset quality threshold) are discharged, they mainly enter the grinding chamber of the grinding component 122 for grinding. Therefore, before, simultaneously with, or after the soybeans enter the grinding inlet 121a, it is necessary to control the grinding component 122 to start operation, ensuring that the grinding operation can be smoothly connected and executed after the soybean weighing operation.
[0181] Next, in the second embodiment provided by the present invention, the coffee grinder may include at least the bean weighing device 200 as described above. More specifically, the drive mechanism 220 in the bean weighing device 200 includes a feed cover 221a that can open or close the feed port 212, a discharge cover 221b that can open or close the discharge port 213, and a drive assembly 222 that drives and connects the feed cover 221a and the discharge cover 221b respectively.
[0182] At this time, the control method of the bean weighing device 200 includes: Step B100: In response to the weighing instruction, the control drive component 222 drives the discharge cover 221b to seal the discharge port 213 and the feed cover 221a to open the feed port 212.
[0183] Step B200: Control the weighing device 230 to start operation and weigh, and obtain the actual mass value of the soybean material received in the receiving cavity 211.
[0184] Step B300: After the actual quality value reaches the preset quality threshold, control the drive component 222 to drive the feed cover 221a to seal the feed port 212.
[0185] In this embodiment, the focus is on detailing how the drive mechanism 220 drives external soybeans into the receiving chamber 211 through the feed inlet 212 and how it drives the soybeans in the receiving chamber 211 to be discharged outward through the discharge outlet 213.
[0186] Before the weighing instruction is triggered, the relative positions of the feed cover 221a and the discharge cover 221b are not restricted. For example, the feed cover 221a can keep the feed port 212 sealed, and the discharge cover 221b can keep the discharge port 213 sealed.
[0187] Alternatively, in one embodiment as described above, when the feed cover 221a and the discharge cover 221b move alternately in opposite directions, the feed cover 221a can remain closed at the feed inlet 212, while the discharge cover 221b is driven to open the discharge outlet 213. Since the feed inlet 212 is generally oriented upwards compared to the discharge outlet 213, it is relatively easier for external impurities to enter. This ensures that in standby or idle states, the feed inlet 212 is well sealed, effectively preventing external impurities from entering the receiving cavity 211.
[0188] After the weighing command is triggered, the drive component 222 drives the discharge cover 221b to seal the discharge port 213 and the feed cover 221a to open the feed port 212. The two actions can be performed almost simultaneously. Or at least, the discharge cover 221b must be ensured to seal the discharge port 213 before the feed cover 221a opens the feed port 212.
[0189] Next, the external soybean material can enter the receiving chamber 211 through the feed inlet 212 under the action of gravity or driven by an external force. The weighing device 230 starts and operates the weighing function as described above.
[0190] When the actual weight of the soybeans received in the receiving cavity 211 reaches the preset weight threshold, the drive component 222 must immediately drive the feed cover 221a to seal the feed port 212 and stop the continued intake of external soybeans. At the same time or after this, the drive component 222 drives the discharge cover 221b to open the discharge port 213 and discharge the weighed soybeans.
[0191] It should be noted that for the parts not described in the second embodiment, you may refer to the first embodiment, which will not be elaborated here.
[0192] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
