Description

Bean grinder and control method, control device and storage medium thereof

[0001] The present application claims priority to the Chinese patent application No. 202411012649.5, filed on July 26, 2024, to the Chinese Patent Office, the whole content of the above application being incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of bean grinders, in particular to a bean grinder and a control method, control device and storage medium thereof. BACKGROUND

[0003] Extracting a cup of high-quality coffee requires considering many elements, and one of the factors that has a greater impact is the coffee powder. The ratio of coffee powder to water directly affects the extraction effect of coffee, which we usually call extraction rate. Baristas have a higher requirement for extraction rate in order to make better coffee.

[0004] Currently, the bean grinders on the market generally cannot accurately calculate the weight of coffee powder needed to make each cup of coffee, resulting in a large fluctuation in the weight of coffee powder for each cup of coffee, leading to waste of coffee beans and rising business costs. Therefore, the present bean grinder uses a weighing device pre-installed outside the whole machine to weigh the powder discharged by the bean grinder to, for example, a powder bowl. However, since the weighing device is installed outside the whole machine, on the one hand, it increases the complexity of the structure outside the whole machine, and on the other hand, since the side components outside the whole machine can easily interfere with the weighing device during use, long-term use can cause the weighing accuracy of the weighing device to be inaccurate, reducing the weighing effect. TECHNICAL PROBLEM

[0005] The main purpose of the present application is to provide a bean grinder and a control method, control device and storage medium thereof, aiming to solve the problem that the existing bean grinders cannot accurately weigh the amount of coffee powder. TECHNICAL SOLUTION

[0039] Please refer to FIGS. 1-6, the present application provides a bean grinder. The bean grinder includes a machine body and a control device 700. The bean grinder can grind bean materials to obtain powder materials. The bean materials can be coffee beans, soybeans, etc. For the sake of convenience, the following description takes coffee beans as the bean materials and coffee powder as the powder materials.

[0040] Specifically, the machine body includes a machine shell 100, a grinding module 200 and a weighing module 300. The machine shell 100 has a receiving cavity formed therein, which can accommodate the grinding module 200 and the weighing module 300.

[0041] The grinding module 200 can be, but is not limited to, comprising a grinding cylinder 210 and a grinding mechanism 220. The grinding cylinder 210 is internally formed with a grinding cavity; the grinding mechanism 220 comprises, for example, two knife plates that are relatively movably arranged and a first driving assembly that drives at least one of the knife plates to move. The grinding gap between the two knife plates is used for grinding and crushing operations such as piercing, milling, and stirring on the granular materials such as coffee beans. When at least one of the two knife plates is movably adjusted in the direction of approaching and moving away from the other, the size of the grinding gap can be adjusted, so that the particle size of the ground powder can be coarsely or finely adjusted. The coarseness or fineness of the particle size of the coffee powder will cause the extraction time of the coffee powder in the powder outlet pipeline 110 to change under the same extraction environment and conditions.

[0042] The grinding module 200 can directly access coffee beans from the outside of the machine shell 100. Alternatively, in an application, the machine body further comprises a bean bin 600. The bean bin 600 can be directly arranged at the upper end of the machine shell 100, or at least partially accommodated in the machine shell 100. The bean bin 600 is a container assembly that can provide a space to accommodate coffee beans. In actual applications, the bean bin 600 can be set to one or several according to actual needs. When the bean bin 600 is set to several, each bean bin 600 can be used to store the same coffee beans, or to store different types of coffee beans.

[0043] It should be noted that when the bean bin 600 is set to several and stores different coffee beans respectively:

[0044] The grinding module 200 can be set to several one by one with the bean bin 600. It can be understood that the coffee beans stored in each bean bin 600 can be used to prepare different types of beverages according to actual needs. At this time, different types of coffee beans and / or different types of beverages can be set one by one with different grinding modules 200, so that the parameters of the knife plates of the grinding module 200, such as the grinding gap of the knife plates and the grinding time of the knife plates, are well adapted to the type of coffee beans and / or beverages one by one, so as to correspondingly prepare beverages with better quality. When the parameters of the knife plates of each grinding module 200 are adjusted in place, they can be directly called and normally used for preparing beverages after storage without repeated adjustment of the parameters of the knife plates. In this way, it helps to simplify the adjustment procedure of the parameters of the knife plates, and makes the grinding accuracy of the grinding module 200 relatively higher and the service life relatively longer.

[0045] Alternatively, the same grinding module 200 is adapted with at least two bean hoppers 600. As described above, each bean hopper 600 stores coffee beans of different types, and each type of coffee beans can be used to prepare a different type of beverage. In this case, different types of coffee beans and / or different types of beverages can correspond to different parameters of the same grinding module 200, such as the grinding gap of the blade, the grinding time of the blade, etc., so as to correspondingly prepare a beverage of better quality. When it is determined that a beverage needs to be prepared, the parameters of the blade of the grinding module 200 corresponding to the beverage need to be adjusted first; when it is determined that another beverage needs to be prepared, the parameters of the blade of the same grinding module 200 need to be adjusted again. In this way, the number of grinding modules 200 can be simplified, and the structure of the whole machine can be simplified.

[0046] Generally, the machine body further comprises a powder outlet pipeline 110, at least a downstream pipe section of the powder outlet pipeline 110 is arranged outside the machine shell 100; an upstream pipe section of the powder outlet pipeline 110 can also be arranged outside the machine shell 100 or penetrate the machine shell 100 to the accommodation cavity according to actual needs. The powder outlet pipeline 110 is used to finally discharge the powder obtained by grinding by the grinding module 200.

[0047] The weighing module 300 is arranged in the machine shell 100 and is used to weigh the powder transferred to the powder outlet pipeline 110 by the grinding module 200. That is, the weighing module 300 needs to complete the weighing operation of the powder at the same time or before the powder enters the powder outlet pipeline 110.

[0048] To this end, in an embodiment, the weighing module 300 comprises a receiving part 310 formed with a receiving cavity for receiving the powder discharged by the grinding module 200 and a weighing part 320 for weighing the powder received by the receiving cavity. The receiving cavity is used to receive the powder, and the weighing part 320 is used to weigh the powder received by the receiving cavity. It can be understood that the receiving of the powder by the receiving cavity and the weighing by the weighing part 320 can be performed simultaneously or the weighing can be performed after a certain time delay after the powder is received. Generally, when the parameters of the blade of the grinding module 200 are normal, the amount of powder that can be ground by the blade each time is basically within a set range (i.e., a preset weight value). The preset weight value corresponds to the weight value of the liquid required for subsequent brewing of the powder, the thickness value of the powder cake, etc., so that a coffee beverage of better quality can be finally brewed. Therefore, in actual operation, when the powder weighed by the weighing part 320 reaches the preset weight value, that is, it is assumed that the grinding module 200 has completed grinding, the powder can be transferred to the powder outlet pipeline 110.

[0049] In a specific embodiment, the receiving portion 310 can be specifically a bottom-sealed and top-opened container structure, such as a conventional cup shape. Based on this, when it is required to receive the powder, the opening of the receiving portion 310 constitutes the upstream of the receiving portion 310, and can be in communication with the downstream of the grinding module 200, specifically, for example, the downstream of the grinding cylinder 210, such as being arranged directly below the downstream of the grinding cylinder 210, so as to receive the powder under the action of gravity. When it is required to transfer the powder to the powder outlet pipeline 110, the opening of the receiving portion 310 becomes the downstream of the receiving portion 310, and can be in communication with the upstream of the powder outlet pipeline 110, and specifically, for example, by means of pouring the receiving portion 310, by means of external suction force, etc., to transfer the powder in the receiving cavity to the powder outlet pipeline 110.

[0050] Alternatively, in a specific embodiment, the receiving portion 310 comprises a receiving body 311 provided with a passage, and an opening and closing member 312 movably arranged in the passage, the opening and closing member 312 having a first position for movably opening the passage, and a second position for movably closing the passage; when moved to the second position, the opening and closing member 312 and the passage jointly define a receiving cavity. In this way, when it is required to receive the powder, the opening and closing member 312 can be operated to move to the second position; when it is required to transfer the powder, without moving the receiving body 311 or the powder outlet pipeline 110, the opening and closing member 312 can be operated to move to the first position.

[0051] Specifically, the number of the opening and closing members 312 can be one or at least two. When the number is one, the opening and closing member 312 can be moved between the first position and the second position by means of, for example, translational movement, rotational movement, etc. When the number is at least two, each opening and closing member 312 can be arranged to be in the second position when moved close, and in the first position when moved away. For a single opening and closing member 312, its movement mode can also be arranged to be translational and / or rotational according to actual requirements.

[0052] The opening and closing member 312 can be arranged at any position of the receiving body 311, such as the upstream section, the downstream section or the downstream end of the passage. For example, as shown in FIGS. 2 to 4, the opening and closing member 312 is generally plate-shaped or sheet-shaped, and is movably arranged at the downstream end of the passage, and specifically, is translational outside the passage.

[0053] The driving force for the movement of the opening and closing member 312 can be manually operated by the user or can be provided by a driving mechanism 313. The driving mechanism 313 can be dedicated to the weighing module 300 or can be provided in another module of the bean grinder and reused to drive the opening and closing member 312 to move between the first position and the second position when the weighing module 300 is in operation. The driving mechanism 313 can include at least a driver such as an electric motor, a pneumatic cylinder or the like. Of course, the driving mechanism 313 can also be formed by a combination of the driver and a transmission assembly. The transmission assembly can be designed to perform, for example, a reversing operation, a speed adjustment operation, a position adjustment operation according to the current installation environment, etc.

[0054] In order to achieve the purpose of weighing the powder received by the receiving portion 310, the weighing portion 320 can be fixedly connected with the receiving portion 310 to jointly weigh the powder received by the receiving body 311, the opening and closing member 312 and the receiving cavity according to actual needs. At this time, the fixed connection between the weighing portion 320 and the receiving portion 310 can be achieved by one-piece forming or by detachable or non-detachable connection after separate forming. When separate forming is adopted, the weighing portion 320 and the receiving portion 310 can be directly connected or indirectly connected through other mounting structures. When the weighing portion 320 is integrally connected with the receiving portion 310, the weight values of the receiving body 311, the opening and closing member 312 and the powder received by the receiving cavity can be obtained simultaneously. Since the weight values of the receiving body 311 and the opening and closing member 312 are basically unchanged, the weight value of the powder can be indirectly determined.

[0055] It should be noted that when the receiving body 311, the opening and closing member 312 and the powder received by the receiving cavity are jointly weighed, the receiving body 311 and the opening and closing member 312 are arranged to be suspended in the casing 100 and are basically not directly connected with other components such as the casing 100, so as to ensure that the receiving body 311 and the opening and closing member 312 are the only components that apply force to the weighing portion 320. Further, the receiving body 311 and the opening and closing member 312 can be arranged to be vertically above the weighing portion 320 and apply downward pressure to the weighing portion 320 to obtain the weight value, or can be arranged to be vertically below the weighing portion 320 and apply downward tension to the weighing portion 320 to obtain the weight value. Of course, the above mainly refers to the connection between the receiving body 311 / opening and closing member 312 and the weighing portion 320, and does not mean that the receiving body 311 / opening and closing member 312 as a whole need to be arranged vertically above or below the weighing portion 320.

[0056] Since the powder meeting the preset weight value needs to be transferred to the powder outlet pipeline 110 after the weighing operation is completed, in an embodiment, if the powder outlet pipeline 110 is also arranged to be suspended at the machine housing 100, that is, substantially not directly connected with other components such as the machine housing 100, the contact type communication connection between the receiving body 311 and the powder outlet pipeline 110 can be achieved, that is, the two can be directly integrally formed or can be connected in a detachable or non-detachable manner after being formed in a separate manner. At this time, it can be understood that the weighing part 320 also weighs the powder outlet pipeline 110 in addition to the above-mentioned receiving body 311, the opening and closing part 312 and the powder received by the receiving cavity.

[0057] However, generally, the powder outlet pipeline 110 cannot be completely suspended at the machine housing 100, but is fixedly installed at the machine housing 100, so it can be understood that in a further scheme, the receiving body 311 and the powder outlet pipeline 110 are formed in a separate manner, and the downstream of the channel and the upstream of the powder outlet pipeline 110 are in non-contact communication. Among them, the non-contact communication means that the receiving body 311 and the powder outlet pipeline 110 are substantially not in contact, and there is no interaction force between them to affect the weighing measurement of the weighing part 320.

[0058] Specifically, when the powder outlet pipeline 110 includes an upstream pipe segment and the receiving body 311 includes a downstream part, the inner diameter of the upstream pipe segment is greater than the outer diameter of the downstream part of the receiving body 311, and the upstream pipe segment is sleeved on the periphery of the downstream part of the receiving body 311. That is, the upstream pipe segment and the downstream part of the receiving body 311 are nested but not in contact, which can avoid forming a radial gap directly between the downstream part of the receiving body 311 and the upstream pipe segment, thereby effectively preventing the powder transferred to the powder outlet pipeline 110 through the receiving body 311 from being dispersed outside the receiving body 311 and the powder outlet pipeline 110, which on the one hand leads to the loss of the powder discharged outward through the powder outlet pipeline 110, resulting in the reduction of the quality of the coffee beverage obtained by the final brewing; on the other hand, it can cause pollution to the environment inside the machine housing 100, and the powder can also block the power output, power input part of the driving mechanism 313, etc., resulting in the influence of power transmission of the power mechanism.

[0059] In order to make the upstream pipe segment and the downstream part of the receiving body 311 not in contact as much as possible, specifically, the upstream pipe segment can be arranged to be flared, that is, the pipe diameter of the upstream pipe segment gradually increases in the direction close to the receiving body 311. In this way, the flared portion forms an inclined guide surface to gather the powder discharged through the receiving body 311 to the upstream pipe segment for concentrated flow.

[0060] When the upstream of the powder outlet pipe 110 and the downstream of the receiving part 310 are spaced apart as described above, the grinder further comprises a baffle extending from the upstream of the powder outlet pipe 110 towards the downstream of the receiving part 310 and at least partially surrounding the periphery of the downstream part of the receiving part 310. The baffle can be arranged only to stop the powder on one side of the powder outlet pipe 110 in the circumferential direction, or can be arranged around the entire circumferential side of the powder outlet pipe 110. The baffle can extend from the powder outlet pipe 110 towards the downstream of the receiving part 310, in which case the baffle can be in contact with or not in contact with the receiving part 310. Conversely, the baffle can also extend from the downstream of the receiving part 310 towards the upstream of the powder outlet pipe 110, in which case the baffle can be in contact with or not in contact with the powder outlet pipe 110.

[0061] Alternatively, when the upstream of the powder outlet pipe 110 and the downstream of the receiving part 310 are also spaced apart, the grinder further comprises a connecting pipe connecting the upstream of the powder outlet pipe 110 and the downstream of the receiving part 310, the connecting pipe being used to guide the powder discharged from the receiving part 310 to the powder outlet pipe 110. The connecting pipe can be arranged as a straight pipe, a curved pipe, a rigid pipe body or a flexible pipe body according to actual needs.

[0062] In order to be able to weigh the powder received by the receiving part 310, the weighing part 320 can also be connected and fixed only with the opening and closing part 312 to jointly weigh the opening and closing part 312 and the powder received by the opening and closing part 312 according to actual needs. In this case, the connection and fixation between the weighing part 320 and the opening and closing part 312 can be achieved by one-piece molding, or can be achieved by detachable or non-detachable connection after separate molding. When separate molding is adopted, the weighing part 320 and the opening and closing part 312 can be directly connected or indirectly connected through other mounting structures. When the weighing part 320 is connected and fixed only with the opening and closing part 312, the weight of the opening and closing part 312 and the weight of the powder received by the receiving cavity can be obtained simultaneously and are not affected by the receiving main body 311. Since the weight of the opening and closing part 312 is basically unchanged, the weight of the powder can be indirectly determined.

[0063] Specifically, one end of the opening and closing member 312 (for ease of understanding, this end is named as the mounting end) is rotatably connected to one side wall of the passage, so as to drive the other end of the opening and closing member 312 (for ease of understanding, this end is named as the free end) to be flipped upward to the second position and flipped downward to the first position. At this time, the weighing part 320 can be a stress sheet arranged on the opening and closing member 312 and close to the free end. When the opening and closing member 312 receives the powder, the powder can directly apply force to the stress sheet. Alternatively, the weighing part 320 can be a force sensor arranged at the mounting end. When the opening and closing member 312 receives the powder, the powder can generate a torque on the opening and closing member 312, which is sensed by the weighing part 320.

[0064] Then, in order to minimize the residual powder on the side wall of the passage, in one scheme, the passage can be arranged in a flared manner from its upstream to its downstream, that is, in a tapered shape, which helps to prevent the powder from gathering at the connection between the outer periphery of the opening and closing member 312 and the side wall of the passage during the falling of the powder, and further helps to improve the accuracy of the weighing value of the weighing part 320. In addition, the side wall of the passage can be subjected to a smoothing treatment, such as reducing the roughness, adding a layer of lubricating material, etc. In addition, the side wall of the passage can be coated with an anti-static coating to avoid static adsorption of the powder, etc.

[0065] When the weighing part 320 is directly connected and fixed with the opening and closing member 312, or in the above-mentioned scheme, the weighing part 320 co-weighs the receiving part 310 and the powder outlet pipe 110, the receiving main body 311 is connected and fixed with the powder outlet pipe 110, that is, directly or indirectly connected in contact communication through some connecting structure. The connection and fixing mode of the receiving main body 311 and the powder outlet pipe 110 can be integrally formed; or can be separately formed and connected in a detachable or non-detachable manner.

[0066] And among them, since the receiving main body 311 and the powder outlet pipe 110 are connected and fixed, when the weighing part 320 is arranged to weigh at least the receiving main body 311, the powder outlet pipe 110 is arranged to be suspended in the cabinet 100. In this way, the weighing part 320 can weigh the powder outlet pipe 110 together, ensuring that the entire weighing process is not affected by the cabinet 100 and does not hinder the direct transfer of the powder.

[0067] In addition, the grinding module 200 and the powder outlet pipe 110 can be arranged in a position-fixed manner, and an installation space can be reserved between the downstream of the grinding module 200 and the upstream of the powder outlet pipe 110:

[0068] Based on this, in an embodiment, the receiving part 310 is fixedly arranged between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110, i.e., at the installation space. In this way, the position of the receiving part 310 relative to the grinding module 200 and / or the powder outlet pipeline 110 is basically maintained unchanged, and there is no need to repeatedly switch the on-off relationship of the grinding module 200, the receiving part 310 and the powder outlet pipeline 110. However, it should be noted that this does not constitute a limitation on the specific connection mode between the grinding module 200 and the receiving part 310, and between the receiving part 310 and the powder outlet pipeline 110. According to actual needs, the grinding module 200 and the receiving part 310, and the receiving part 310 and the powder outlet pipeline 110 can be selectively arranged in a contact type communication connection or a non-contact type communication connection.

[0069] Alternatively, in an embodiment, at least the receiving part 310 is movably arranged relative to the machine housing 100 to have a powder receiving position located between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110, and an avoiding position away from the powder receiving position. That is, when the powder needs to be received and weighed, the receiving part 310 can be moved to the above-mentioned installation space to realize the butt joint with the grinding module 200 and the powder outlet pipeline 110, and be in the powder receiving position; and when the powder does not need to be received and weighed, the receiving part 310 can be moved away from the above-mentioned installation space, and be in the avoiding position.

[0070] Further, when the receiving part 310 is in the avoiding position, the above-mentioned installation space is empty, and it is easy to pull apart the communication distance between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110, and it is easy to cause the powder discharged outward through the downstream of the grinding module 200 to fly before entering the upstream of the powder outlet pipeline 110, resulting in powder loss and other problems. Therefore, in an embodiment, the grinding module 200 and / or the powder outlet pipeline 110 can be movably arranged relative to the machine housing 100, so that after the receiving part 310 is moved to the avoiding position, the grinding module 200 and / or the powder outlet pipeline 110 can be moved close to each other to fill the above-mentioned installation space, so that the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110 are directly connected in communication; conversely, before the receiving part 310 is moved to the powder receiving position, the grinding module 200 and / or the powder outlet pipeline 110 are first operated to move away from each other to make room for the above-mentioned installation space for the receiving part 310 to move in. Alternatively, in an embodiment, a telescopic deformation communication structure can be arranged between the grinding module 200 and the powder outlet pipeline 110. After the receiving part 310 is moved to the avoiding position, the communication structure is elongated and deformed to communicate between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110, so as to fill the above-mentioned installation space; conversely, before the receiving part 310 is moved to the powder receiving position, the communication structure is first operated to be shortened and deformed to make room for the above-mentioned installation space for the receiving part 310 to move in.

[0071] The grinder may need to weigh the powder in some modes during its daily use, and may not need to weigh the powder in some modes. That is, the weighing module 300 can be provided with a weighing mode and a non-weighing mode, and can be flexibly switched between the weighing mode and the non-weighing mode.

[0072] In an embodiment, the weighing mode and the non-weighing mode of the weighing module 300 can be directly realized by program control. Specifically, when the receiving part 310 is located between the downstream of the grinding module 200 and the upstream of the powder outlet pipe 110, the weighing part 320 can be controlled to start and stop, so that the weighing module 300 has the weighing mode when the weighing part 320 is enabled, and has the non-weighing mode when the weighing part 320 is disabled. For example, the weighing part 320 can be electrically connected with the control device 700, and the weighing part 320 is controlled by the control device 700 to have the weighing mode when it is selected to be enabled, and has the non-weighing mode when it is selected to be disabled. The weighing part 320 is enabled, which can be embodied in, for example, that the weighing component in the weighing part 320 that mainly plays a weighing function is powered on, the weighing component receives an instruction to start running, etc.; conversely, the weighing part 320 is disabled, which can be embodied in, for example, that the weighing component is powered off, the weighing component receives an instruction to stop running, etc.

[0073] Further, when the receiving body 311 is located between the downstream of the grinding module 200 and the upstream of the powder outlet pipe 110, the weighing part 320 can be controlled to start and stop, so that the weighing module 300 has the weighing mode when the opening and closing piece 312 is moved to the second position and the weighing part 320 is enabled, has the pre-receiving mode when the opening and closing piece 312 is in the second position and the weighing part 320 is disabled, and has the material passing mode when the opening and closing piece 312 is in the first position and the weighing part 320 is disabled. Specifically, the opening and closing piece 312 closes the channel and defines a receiving cavity that can receive the powder, at this time the weighing part 320 is enabled as described above to have the weighing function, and can weigh the powder received in the receiving cavity, so that the weighing module 300 as a whole operates in the weighing mode. The opening and closing piece 312 closes the channel and defines a receiving cavity that can receive the powder, at this time the weighing part 320 is disabled as described above to have the weighing function, and does not weigh the powder received in the receiving cavity, so that the weighing module 300 as a whole operates in the pre-receiving mode, and can pre-receive a certain amount of powder, so that when the powder outlet pipe 110 needs to discharge the powder outward, it is not necessary to wait for the grinding module 200 to start running, and the pre-received powder in the receiving cavity can be directly discharged outward through the powder outlet pipe 110. The opening and closing piece 312 opens the channel, and the weighing part 320 is disabled as described above to have the weighing function, and does not weigh the powder received in the receiving cavity, at this time the weighing module 300 as a whole operates in the material passing mode, and can guide the powder discharged outward by the grinding module 200 to the powder outlet pipe 110, and thus constitutes a transition pipe.

[0074] Of course, in another embodiment, the weighing mode and the non-weighing mode of the weighing module 300 can also be realized by the program control, but also by the installation state switching of the weighing module 300.

[0075] For example, the weighing module 300 is in the weighing mode when the whole weighing module 300 is installed between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110; and the weighing module 300 is in the non-weighing mode when the whole weighing module 300 is not installed between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110.

[0076] For example, the weighing part 320 and the receiving part 310 can be connected in a clutch manner, so that the weighing module 300 has the weighing mode when the weighing part 320 and the receiving part 310 are connected, and has the non-weighing mode when the weighing part 320 and the receiving part 310 are separated. When the weighing part 320 and the receiving part 310 are not connected in place, the weighing part 320 cannot sense the weight change of the receiving part 310, that is, in the non-weighing mode; on the contrary, when the weighing part 320 and the receiving part 310 are connected in place, the weighing part 320 can timely sense the weight change of the receiving part 310, that is, in the weighing mode.

[0077] Of course, the weighing part 320 and the opening and closing part 312 can also be connected in a clutch manner, so that the weighing module 300 has the weighing mode when the weighing part 320 and the opening and closing part 312 are connected, and has the non-weighing mode when the weighing part 320 and the opening and closing part 312 are separated. When the weighing part 320 and the opening and closing part 312 are not connected in place, the weighing part 320 cannot sense the weight change of the opening and closing part 312, that is, in the non-weighing mode; on the contrary, when the weighing part 320 and the opening and closing part 312 are connected in place, the weighing part 320 can timely sense the weight change of the opening and closing part 312, that is, in the weighing mode.

[0078] Based on any of the above embodiments, the powder outlet pipeline 110 can discharge the weighed powder outside the machine shell 100. At this time, the coffee grinder further comprises a powder bowl 400, which can be moved to communicate with the downstream of the powder outlet pipeline 110 to receive the powder discharged by the powder outlet pipeline 110. The movement of the powder bowl 400 can be realized by manual operation of the user, or can be driven by a dedicated power module. When the downstream of the powder outlet pipeline 110 is downward, the powder bowl 400 can be moved to the directly below the powder outlet pipeline 110 to communicate with the powder outlet pipeline 110 to receive the powder discharged by the powder outlet pipeline 110.

[0079] The powder bowl 400 can be directly installed on the platform where the grinder is placed. Alternatively, in a further embodiment, the grinder further comprises a support bracket 500 which is fixedly connected with the outer wall of the casing 100, which can be integrally formed as shown in FIG. 5, or separately formed and then detachably or non-detachably connected as shown in FIGS. 1-2. The support bracket 500 protrudes laterally from the casing 100, and specifically can be located directly below the downstream of the powder outlet pipe 110. The support bracket 500 can provide a fixed installation for the powder bowl 400. The specific structure of the support bracket 500 is adapted to the fixed installation structure required by the powder bowl 400. For example, when the powder bowl 400 can be directly installed on a flat surface, the support bracket 500 only needs to provide a flat surface. When the powder bowl 400 needs to be installed on a concave surface, the support bracket 500 can provide a concave surface or a groove. Details are not described here.

[0080] The support bracket 500 is fixedly connected with the casing 100, and as much as possible, the support bracket 500 does not contact the weighing module 300. In this way, the support bracket 500 and the weighing part 320 and the receiving part 310 in the weighing module 300 are not in contact. Since the support bracket 500 is outside the casing 100, it can interfere with things around it, but this interference will not affect the weighing module 300, and then will not adversely affect the measurement accuracy of the weighing part 320.

[0081] Based on any of the above embodiments, since the grinder is generally placed vertically on the platform, such as on the desktop. Therefore, in actual application, the grinding module 200, the receiving part 310 and the powder bowl 400 are arranged in the vertical direction of the casing 100. Specifically, the grinding cylinder 210, the receiving part 310, the powder outlet pipe 110 and the powder bowl 400 can be arranged in order from top to bottom, so that the powder can naturally fall in turn, reducing the residual amount in the flow process.

[0082] In addition, based on any of the above embodiments, the casing 100 near the support bracket 500 is provided with a sensor device for detecting whether the powder bowl 400 is placed in place on the support bracket 500. The sensor device can be, but is not limited to, a photoelectric sensor, a weight sensor, an image recognition sensor, etc., which can identify and confirm whether the powder bowl 400 is installed in place.

[0083] The grinder further comprises an input module. The parameters that need to be input in advance can use the touch liquid crystal display screen of the grinder as the input module of the preset parameters, and in addition, can be input by connected external devices, such as mobile phones, tablet computers, notebook computers, PDA and other mobile devices, to form the input module. In a preferred embodiment, the grinder is provided with a touchable liquid crystal display screen, and the above-mentioned parameters can be selectively presented on the display screen, and the parameter input can be realized through touch.

[0084] The grinder further comprises a display and control module. At least a display and control panel of the display and control module is exposed outside the casing 100 to be manually operated by a user. The control buttons of the display and control module constitute the input module as described above. The display part of the display and control module can display preset numbers, characters, patterns, etc. to assist the user to understand the status of the parameter calibration, parameter adjustment, normal use, etc. of the grinder. The operation interface of the display and control module will be described in detail below in combination with specific drawings.

[0085] The control device 700 comprises a memory 750, a processor 710, and a control program of the grinder stored in the memory 750 and executable on the processor 710.

[0086] Referring to FIG. 6, FIG. 6 is a structural schematic diagram of the control device 700 of the hardware operating environment involved in the embodiment of the present application.

[0087] As shown in FIG. 6, the control device 700 can comprise a processor 710, such as a central processing unit 710 (CPU), a communication bus 720, a user interface 730, a network interface 740, and a memory 750. The communication bus 720 is used to realize the connection and communication among these components. The user interface 730 can comprise a display and an input unit such as a keyboard. The optional user interface 730 can further comprise a standard wired interface and a wireless interface. The network interface 740 can optionally comprise a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 750 can be a high-speed random access memory 750 (RAM) or a stable non-volatile memory 750 (NVM), such as a magnetic disk storage device. The memory 750 can optionally be a storage device independent of the aforementioned processor 710.

[0088] Based on different functional configurations of the grinder, corresponding sensors and functional modules can be set to measure or monitor the aforementioned parameter values, and transmit the real-time or preset values to the processor 710 to realize various functional combinations among different parameter modules.

[0089] Those skilled in the art can understand that the structure shown in FIG. 6 does not constitute a limitation on the control device 700, and can comprise more or fewer components than shown, or combine certain components, or different component arrangements.

[0090] As shown in FIG. 6, the memory 750 as a storage medium can include an operating system, a network communication module, a user interface 730 module, and a control program of the coffee grinder.

[0091] In the control device 700 shown in FIG. 6, the network interface 740 is mainly used for data communication with a network server; the user interface 730 is mainly used for data interaction with a user; the processor 710 and the memory 750 in the control device 700 of the application can be arranged in the coffee grinder, and the control device 700 calls the control program of the coffee grinder stored in the memory 750 through the processor 710, and executes the control method of the coffee grinder provided by the embodiments of the application.

[0092] In addition, the application further provides a control method of a coffee grinder. It should be noted that the coffee grinder can be the coffee grinder of any of the above embodiments, or can be other coffee grinders different from the above.

[0093] Please specifically combine FIG. 7, in the first embodiment of the control method of the coffee grinder provided by the application, the coffee grinder at least includes a shell 100, a powder outlet pipeline 110, a grinding module 200, and a weighing module 300. The control method of the coffee grinder includes:

[0094] Step A100: controlling the grinding module 200 to start running and transfer the powder to the weighing module 300;

[0095] Step A200: controlling the weighing module 300 to receive the powder and weigh the received powder, and controlling the grinding module 200 to stop running when the weight of the received powder reaches a preset weight value;

[0096] Step A300: controlling the weighing module 300 to transfer the weighed powder to the powder outlet pipeline 110.

[0097] In this embodiment, the control device 700 first controls the grinding module 200 to start running, and starts the weighing module 300 in the weighing mode at the same time, in advance, or after a certain time delay when the grinding module 200 starts running. In this way, when the coffee beans are ground into powder by the grinding module 200 and discharged outward through its downstream, the weighing module 300 can simultaneously receive and measure the weight of the received powder, so that when the weight of the powder received by the weighing module 300 reaches a preset weight value, the communication between the grinding module 200 and the weighing module 300 is immediately cut off, and / or the grinding module 200 is immediately controlled to stop working, so as to avoid the weighing module 300 continuously receiving the material, resulting in overloading of the coffee powder.

[0098] And before step A100, it further includes:

[0099] Step A111: confirming whether the weighing module 300 is installed in place downstream of the grinding module 200;

[0100] Step A112: if yes, confirming whether the weighing module 300 is enabled in the weighing mode;

[0101] Step A113: if yes, controlling the weighing value of the weighing module 300 to be zeroed, and then controlling the grinding module 200 to start running and transfer the powder to the weighing module 300.

[0102] In the present embodiment, since the weighing module 300 can be movably arranged, it has a powder receiving position installed between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110, and an uninstalled state removed from between the downstream of the grinding module 200 and the upstream of the powder outlet pipeline 110. In the above steps, first, it can be automatically detected and confirmed whether the weighing module 300 is installed in the cabinet 100, and whether it is installed in place in the cabinet 100, based on a preset sensor device. If the weighing module 300 has been installed in the cabinet 100, but is not installed at the designated installation area, or there is an abnormality in the installation direction, etc., that is, it is not installed in place in the cabinet 100. The sensor device can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the weighing module 300.

[0103] When it is confirmed that the weighing module 300 has been installed in the cabinet 100 and installed in place in the cabinet 100, it is necessary to confirm whether the weighing module 300 is enabled in the weighing mode. As known from the above, the weighing module 300 is optionally provided with a weighing mode and a non-weighing mode, wherein when in the weighing mode, the weighing module 300 can measure the weight of the transferred and received powder; when in the non-weighing mode, the weighing module 300 can receive the powder, or only act as a transition pipeline for the powder to flow from the downstream of the grinding module 200 to the upstream of the powder outlet pipeline 110.

[0104] When it is confirmed that the weighing module 300 has been enabled in the weighing mode, further, the weighing value of the weighing module 300 can also be zeroed to reduce the influence of the weighing module 300 itself on the powder weight deviation as much as possible. Then, in the process of the grinding module 200 continuously discharging powder to the weighing module 300, the weight of the powder received by the weighing module 300 can be measured in real time to form the actual powder weight. When the actual powder weight of the powder received by the weighing module 300 gradually increases to reach a preset weight value, the preset powder weight of the powder is locked by controlling the grinding module 200 to stop grinding and discharging powder, and / or by controlling the weighing module 300 to stop receiving powder, and the powder is transferred to the powder outlet pipeline 110 for discharge to the outside by the powder outlet pipeline 110.

[0105] In addition, when the coffee grinder further comprises an input module for the user to input parameters and / or control instructions, the step A100 comprises:

[0106] Step A121: confirming whether a start instruction input by the user through the input module is received;

[0107] Step A122: if yes, controlling the grinding module 200 to start running and transferring the powder to the weighing module 300.

[0108] In the embodiment, whether the grinding module 200 starts running can be determined by whether the user inputs a start instruction through the input module. When the user inputs a start instruction through the input module, the control device 700 receives the start instruction and starts the grinding module 200 to run, so as to achieve the purpose of grinding the bean material to obtain the powder and transfer the powder to the receiving part 310 of the weighing module 300.

[0109] In addition, please refer to FIG. 8, the present application provides a second embodiment of a control method of a coffee grinder, which specifically comprises a powder outlet pipeline 110, a grinding module 200, a weighing module 300 and a powder bowl 400, and the control method of the coffee grinder comprises:

[0110] Step B100: confirming whether the powder bowl 400 is placed in place downstream of the powder outlet pipeline 110;

[0111] Step B200: if yes, controlling the grinding module 200 to start running and transferring the powder to the weighing module 300;

[0112] Step B300: controlling the weighing module 300 to receive the powder and weigh the received powder, and controlling the grinding module 200 to stop running when the weight of the received powder reaches a preset weight value;

[0113] Step B400: controlling the weighing module 300 to transfer the weighed powder to the powder outlet pipeline 110, so as to discharge the powder from the powder outlet pipeline 110 to the powder bowl 400.

[0114] In the embodiment, the schemes of steps B200 to B400 are basically the same as those of steps A100 to A300, and will not be described herein. In step B100, the control device 700 first needs to confirm whether the powder bowl 400 is placed in place downstream of the powder outlet pipeline 110, for example, at the support bracket 500, which can be sensed and confirmed by a sensor arranged downstream of the powder outlet pipeline 110, for example, at the support bracket 500.

[0115] When the powder bowl 400 is not placed in place, to prevent waste of powder, the grinding module 200 can be optionally controlled to start running; or the grinding module 200 can be optionally controlled to start running, the weighing module 300 can be controlled to receive and weigh the powder, but the weighing module 300 is not controlled to transfer the weighed powder to the powder outlet pipeline 110.

[0116] In addition, please refer to FIG. 9, the present application provides a third embodiment of a control method of a coffee grinder, the coffee grinder comprising a grinding module 200, a weighing module 300 and a powder bowl 400, the control method of the coffee grinder comprising:

[0117] Step C100: obtaining a preset weight value of single grinding powder;

[0118] Step C200: determining whether the automatic mode or the manual mode is currently selected to be enabled;

[0119] Step C300: after determining that the automatic mode is currently selected to be enabled, confirming whether the powder bowl 400 is placed in place, and automatically running the grinding module 200 after confirming that the powder bowl 400 is placed in place; or after determining that the manual mode is currently selected to be enabled, prompting the user to manually run the grinding module 200;

[0120] Step C400: controlling the grinding module 200 to transfer the powder to the weighing module 300;

[0121] Step C500: controlling the weighing module 300 to receive the powder and weigh the received powder, and controlling the grinding module 200 to stop running when the weight of the received powder reaches the preset weight value;

[0122] Step C600: controlling the weighing module 300 to transfer the weighed powder to the powder bowl 400.

[0123] In this embodiment, the preset weight value can be first obtained. In this embodiment, the obtaining method of the preset weight value is not limited, which can be stored in the memory 750 of the control device 700, and when needed, the corresponding data can be directly called from the memory 750 by the processor 710. Alternatively, the preset weight value can also be obtained by the user to input on site or pre-input. At this time, the coffee grinder can actively remind the user to input the corresponding data based on the input module, or the user can actively input the corresponding data based on the input module. The ways to remind the user are various, which can be but not limited to the light signal of the warning light, the prompt sound of the buzzer, the message push received by the mobile device in communication connection with the control device 700, etc.

[0124] The specific value of the preset weight value can be directly determined by the user according to experience, or can be determined by a specific requirement association. The specific requirement is, for example, related to quality parameters such as taste, mouthfeel, and the like of the coffee beverage prepared; related to the type of coffee beans, the extraction method, and the like. The preset weight value can be a fixed point value, or a range value within a suitable range.

[0125] In addition, the grinder also provides two choices of automatic mode and manual mode through, for example, the input module described above, which can be selected by the user manually. When it is determined that the automatic mode is selected, it is necessary to automatically determine whether the powder bowl 400 is placed in place, and then automatically start the operation of the grinding module 200 after confirming that the powder bowl 400 is placed in place. When it is determined that the manual mode is selected, the user needs to determine whether the powder bowl 400 is placed in place, and then manually trigger the start of the operation of the grinding module 200 after confirming that the powder bowl 400 is placed in place.

[0126] When the grinding module 200 starts to operate, the subsequent steps C400 to C600 can refer to the steps A100 to A300 described above, and will not be described one by one.

[0127] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application, using the content of the present application specification and drawings, or directly / indirectly applied to other related technical fields is included in the patent protection scope of the present application.
