[0031] Please refer to Figure 1 , Figure 1 An embodiment of the present application shows a beverage machine 100.

[0032] In embodiments of the present application, the beverage machine 100 can include a bean grinding device 101 and an extraction device 102.

[0033] In embodiments of the present application, the type of the bean material is not specifically limited. For example, the bean material can be, but is not limited to, coffee beans, soybeans, etc.

[0034] For example, the bean material can be coffee beans, and the powder material can be coffee powder obtained by grinding the coffee beans.

[0035] It can be understood that the principle of the extraction device 102 extracting the powder material to generate beverage can be the same as or similar to the general principle of a coffee machine extracting coffee powder to generate coffee liquid in the related art, and will not be described here.

[0036] In some embodiments, the beverage machine 100 can further include a housing (not shown in the figure), and the bean grinding device 101 and the extraction device 102 can be fixedly connected with the housing and at least partially located in the housing.

For another example, the communication connection can be a wireless communication connection realized by functions such as 3G, 4G, 5G, Bluetooth, wireless local area network, etc.

[0041] In embodiments of the present application, the operation that the operator needs to perform on the operation panel 1032 is not specifically limited. For example, a plurality of physical buttons or virtual buttons displayed by images can be provided on the operation panel 1032, and the user can click the corresponding button on the operation panel 1032 to determine the brewing information of the required beverage. For another example, the user can slide the corresponding pattern on the operation panel 1032 by using a finger or a tool adapted to the operation panel 1032 to determine the brewing information of the required beverage.

[0042] In embodiments of the present application, the operation panel 1032 can adopt the operation panel 1032 commonly used in the related field, which will not be described here.

[0043] Please refer to Figure 2 and Figure 3 In embodiments of the present application, the length direction, the width direction and the height direction of the bean grinding device 101 can be defined as the first direction, the second direction and the vertical direction, respectively. For example, the first direction can be the X direction and the opposite direction thereof as shown in Figure 2 and Figure 3 The second direction can be the Y direction and the opposite direction thereof as shown in Figure 2 and Figure 2 The vertical direction can be the Z direction and the opposite direction thereof as shown in Figure 3 and

[0044] In embodiments of the present application, the bean grinding device 101 can include a bean bin mechanism 10, a weighing mechanism 20 and a bean grinding mechanism 30. The bean bin mechanism 10, the weighing mechanism 20 and the bean grinding mechanism 30 can be arranged in the order from high to low in the vertical direction.

[0045] The bean bin mechanism 10 can receive beans. The bean bin mechanism 10 can be fixedly connected with the shell.

[0046] The weighing mechanism 20 can include a weighing assembly 21 and a weight detection member 22. The weighing assembly 21 can be provided with a weighing cavity 2111, and the weighing assembly 21 is provided with a first opening 2112 in the vertical direction towards one side of the bean grinding mechanism 30, the first opening 2112 being in communication with the weighing cavity 2111; the weighing assembly 21 is provided with a first counter interface 2113 in the vertical direction away from one side of the bean grinding mechanism 30, the first counter interface 2113 being in communication with the weighing cavity 2111. The cross-sectional area of the first counter interface 2113 is smaller than that of the first opening 2112. The bean bin mechanism 10 is provided with a second counter interface 1121 in the vertical direction towards one side of the weighing mechanism 20, and the side of the bean bin mechanism 10 provided with the second counter interface 1121 can be inserted into the first counter interface 2113, so that the part of the bean bin mechanism 10 provided with the second counter interface 1121 enters the weighing cavity 2111, thereby making the second counter interface 1121 in communication with the weighing cavity 2111. The bean material received by the bean bin mechanism 10 can enter the weighing cavity 2111 through the second counter interface 1121.

[0047] Please refer to Figure 4 The weight detection member 22 can be in communication with the processor 1031 and connected with the weighing assembly 21. The weight detection member 22 can detect the weight change of the weighing assembly 21 and the bean material in the weighing cavity 2111, so as to determine the weight of the bean material entering the weighing cavity 2111 from the bean bin mechanism 10; the weight detection member 22 can output the detection information corresponding to the weight of the bean material in the weighing cavity 2111 to the processor 1031, and the processor 1031 can determine whether the weight of the bean material in the weighing cavity 2111 reaches the weight corresponding to the preparation information according to the detection information; when the weight of the bean material reaches the weight corresponding to the preparation information, the processor 1031 can control the weighing assembly 21 to work, so that the bean material in the weighing cavity 2111 moves out of the weighing cavity 2111 from the first opening 2112.

[0048] The bean grinding mechanism 30 can be located below the weighing mechanism 20 to receive the weighing mechanism 20. The bean grinding mechanism 30 can be fixedly connected with the shell. In this way, the bean bin mechanism 10, the weighing mechanism 20 and the bean grinding mechanism 30 can be kept relatively fixed. The bean grinding mechanism 30 can be in communication with the first opening 2112, and the bean grinding mechanism 30 can receive the beans in the weighing cavity 2111 through the first opening 2112. The bean grinding mechanism 30 can be in communication with the processor 1031, and when the weight of the beans in the weighing cavity 2111 reaches the weight corresponding to the preparation information, the bean grinding mechanism 30 can be controlled to start working, so that the bean grinding mechanism 30 grinds the received beans to form powder; the processor 1031 can detect whether the bean grinding mechanism 30 completes the grinding processing of all the beans entering the bean grinding mechanism 30, and controls the bean grinding mechanism 30 to stop working after determining that the bean grinding mechanism 30 completes the grinding processing of all the beans. The bean grinding mechanism 30 can be in communication with the extraction device 102, and the bean grinding mechanism 30 can transmit the powder generated by grinding to the extraction device 102. The processor 1031 can control the extraction device 102 to extract the powder according to the preparation information to generate the beverage after controlling the bean grinding mechanism 30 to stop working.

[0049] In the embodiments of the present application, the fixed connection and the fixed installation are not limited in specific forms. For example, the fixed connection can include, but is not limited to, screw fixing, welding fixing, integral forming fixing and buckle fixing.

[0050] It can be understood that the weight detection member 22 can detect the weight of the beans entering the weighing cavity 2111 from the bean bin mechanism 10. When the weight of the beans entering the weighing cavity 2111 reaches a specified weight, the processor 1031 can control the weighing assembly 21 to work, so that the beans in the weighing cavity 2111 can fall into the bean grinding mechanism 30 under the action of gravity through the first opening 2112; the processor 1031 can control the bean grinding mechanism 30 to work synchronously, so that the bean grinding mechanism 30 grinds the beans entering the bean grinding mechanism 30 to generate powder, and transmits the powder to the extraction device 102.

[0051] By weighing the beans through the weighing mechanism 20, the weight of the beans entering the bean bin mechanism 10 for grinding can correspond to the preparation information of the beverage confirmed by the user. Compared with the related art, which determines the amount of beans by the working time of the bean bin mechanism 10 and other factors, the embodiment of the present application can improve the accuracy of the amount of beans by weighing the beans first and then grinding the beans, thereby reducing the probability that the powder generated by the bean grinding mechanism 30 deviates from the powder required by the user when preparing the beverage. In this way, the quality of the beverage prepared by the beverage machine 100 can be improved, and the user experience can be improved.

[0052] In the embodiments of the present application, the type of the weight detecting member 22 is not specifically limited. For example, the weight detecting member 22 can be, but is not limited to, a weight sensor.

[0053] It can be understood that the bean grinding mechanism 30 can include a grinding motor 31, and the processor 1031 can be communicatively connected with the grinding motor 31. The grinding motor 31 can be connected with a cutter 32 for grinding the bean material, and the grinding motor 31 can drive the cutter 32 to rotate to grind the bean material. The processor 1031 can detect the working condition of the grinding motor 31 to determine whether the bean grinding mechanism 30 has completed the grinding of all the bean material entering the bean grinding mechanism 30.

[0054] In the embodiments of the present application, the way in which the processor 1031 determines whether the bean grinding mechanism 30 has completed the grinding of all the bean material by the grinding motor 31 is not specifically limited.

[0055] For example, the processor 1031 can be electrically connected with the grinding motor 31 and monitor the working current of the grinding motor 31. When the grinding motor 31 drives the cutter 32 to rotate to grind the bean material, the contact between the bean material and the cutter 32 will hinder the rotation of the cutter 32, so that the grinding motor 31 needs to increase the working current to increase the driving force for driving the cutter 32 to rotate, so that the cutter 32 can continue to grind the bean material. Thus, the working current of the grinding motor 31 when grinding the bean material can be greater than the working current of the grinding motor 31 when idling, and the working current of the grinding motor 31 when idling can be preset in the processor 1031. The processor 1031 can determine whether the grinding motor 31 is idling or grinding the bean material according to whether the working current of the grinding motor 31 is greater than the working current preset in the processor 1031, and further determine whether the grinding motor 31 has completed the grinding of all the bean material.

[0056] For another example, the grinding motor 31 can include a processing unit (not shown in the figure), and the processing unit can be communicatively connected with the processor 1031. The processing unit can determine the rotation speed of the rotor of the grinding motor 31 and transmit the rotation speed to the processor 1031. The rated rotation speed of the grinding motor 31 when idling can be preset in the processor 1031, and the processor 1031 can determine whether the grinding motor 31 is idling or grinding the bean material according to whether the rotation speed of the grinding motor 31 is higher than the rated rotation speed, and further determine whether the grinding motor 31 has completed the grinding of all the bean material.

[0057] Please refer to Figure 5In some embodiments, the bean grinding device 101 can further include a mounting seat 40. The mounting seat 40 can be located between the weighing mechanism 20 and the bean grinding mechanism 30 in the vertical direction. The mounting seat 40 can be fixedly connected with the shell. The weight detection piece 22 can be fixedly installed on the mounting seat 40 and located on the side of the mounting seat 40 facing the weighing mechanism 20 in the vertical direction. The mounting seat 40 is provided with a first accommodating cavity 41 on the side facing the weighing mechanism 20 and a second accommodating cavity 42 on the side facing the bean grinding mechanism 30. A second opening 43 is provided in the middle of the mounting seat 40 and penetrates the mounting seat 40 in the vertical direction. The second opening 43 communicates with the first accommodating cavity 41 and the second accommodating cavity 42.

[0058] The first accommodating cavity 41 can accommodate the bottom of the weighing assembly 21, so that the mounting seat 40 is sleeved on the bottom of the weighing assembly 21; the bottom of the weighing assembly 21 can abut against the bottom wall of the first accommodating cavity 41, and the first opening 2112 can correspond to the second opening 43. The second opening 43 can communicate with the first opening 2112, so as to realize the communication between the second opening 43 and the weighing cavity 2111.

[0059] The side of the bean grinding mechanism 30 facing the weighing mechanism 20, i.e. the top of the bean grinding mechanism 30, can be provided with a bean grinding feeding port 33. The bean material entering the bean grinding feeding port 33 can move into the bean grinding mechanism 30 and abut against the cutter 32 in the bean grinding mechanism 30, so as to realize the grinding processing of the bean material. The second accommodating cavity 42 can accommodate the top of the bean grinding mechanism 30, so that the mounting seat 40 is sleeved on the top of the bean grinding mechanism 30; the top of the bean grinding mechanism 30 can abut against the top wall of the second accommodating cavity 42. The second opening 43 can be correspondingly arranged with the bean grinding feeding port 33. The bean grinding feeding port 33 can communicate with the second opening 43, so as to realize the communication between the weighing cavity 2111 and the bean grinding mechanism 30.

[0060] It can be understood that the mounting seat 40 can be fixedly connected with the shell; the mounting seat 40 can receive the weighing mechanism 20 through the abutment between the bottom wall of the first accommodating cavity 41 and the weighing mechanism 20, so as to realize the relative fixation between the weighing mechanism 20 and the shell. Meanwhile, the sleeving of the mounting seat 40 on the weighing mechanism 20 and the sleeving of the mounting seat 40 on the bean grinding mechanism 30 can realize the positioning of the weighing mechanism 20 and the bean grinding mechanism 30, so that the bean material in the weighing cavity 2111 can enter the bean grinding mechanism 30 through the first opening 2112, the second opening 43 and the bean grinding feeding port 33 for grinding processing.

[0061] Please refer to Figure 6 In some embodiments, the weighing assembly 21 can include a weighing tank 211 and an extension piece 212, and the weighing mechanism 20 can further include an opening switch assembly 40.

[0062] The weighing tank 211 is provided with a first interface 2113 at the top thereof in the vertical direction and a first opening 2112 at the bottom thereof, and a weighing cavity 2111 is formed in the weighing tank 211. The first accommodating cavity 41 accommodates the bottom of the weighing tank 211. The extension member 212 is fixedly connected to one side of the weighing tank 211 in the first direction. The extension member 212 can be supported on the weight detection member 22.

[0063] The opening switch assembly 23 can include a movable door 231. The movable door 231 can be located in the weighing cavity 2111, and the movable door 231 is rotatably connected to the weighing tank 211. The rotation center axis of the movable door 231 can coincide with the second direction. As shown in Figure 3 When the movable door 231 is at the first angle, the movable door 231 can be perpendicular to the vertical direction, and the movable door 231 can block the first opening 2112 and block the beans in the weighing cavity 2111, so that the beans are all supported on the movable door 231. As shown in Figure 6 When the movable door 231 is at the second angle, the movable door 231 can be perpendicular to the first direction, and the movable door 231 does not block the first opening 2112 at this time. The beans in the weighing cavity 2111 can pass through the first opening 2112 under the action of gravity and enter the bean grinding mechanism 30. When the beans enter the weighing cavity 2111 and are supported on the movable door 231, the gravity of the beans can be transmitted to the weighing tank 211 through the movable door 231 and to the extension member 212 through the weighing tank 211. The weight detection member 22 supporting the extension member 212 can detect the change of the gravity transmitted to the extension member 212, so as to detect the weight of the beans supported on the movable door 231, that is, the weight of the beans in the weighing cavity 2111.

[0064] Please refer to Figure 7The weighing mechanism 20 can further include a driving assembly 24. The driving assembly 24 can be mounted outside the weighing assembly 21, and the driving assembly 24 can be connected with the movable door 231. The driving assembly 24 can be in communication connection with the processor 1031. The driving assembly 24 can drive the movable door 231 to rotate, so that the movable door 231 rotates from the first angle to the second angle, and rotates from the second angle to the first angle. When the movable door 231 is at the first angle and receives the beans, the processor 1031 can control the driving assembly 24 to work when the weight of the beans on the movable door 231 reaches the corresponding weight according to the detection information of the weight detection piece 22, and the driving assembly 24 can drive the movable door 231 to rotate from the first angle to the second angle, so that the beans received by the movable door 231 enter the grinding mechanism 30 through the first opening 2112. When the movable door 231 is at the second angle, the processor 1031 can determine that the beverage machine 100 needs to make a beverage according to the operation of the user on the operation panel 1032, and then control the driving assembly 24 to work, and the driving assembly 24 can drive the movable door 231 to rotate from the second angle to the first angle, so that the weighing mechanism 20 can weigh the beans entering the weighing cavity 2111 to determine whether the weight of the beans ground by the grinding device 101 meets the preparation information determined by the user through the operation panel 1032.

[0065] It can be understood that the beans received by the movable door 231 in the opening switch assembly 23 can make the gravity of the beans transmitted to the extension piece 212, so that the weight detection piece 22 can detect the weight of the beans entering the weighing cavity 2111 by detecting the weight change of the extension piece 212, and the weight detection piece 22 can detect the weight of the beans in the weighing cavity 2111 without entering the weighing cavity 2111, which can improve the convenience of the bean weight detection.

[0066] When the weight of the beans received by the movable door 231 meets the amount of beans required for the beverage machine 100 to make a beverage, that is, the weight of the beans meets the preparation information of the beverage, the movable door 231 can be opened by rotating, so that the first opening 2112 is opened, and the beans originally received on the movable door 231 can fall off from the movable door 231 due to the loss of support, so that the beans that have completed the weighing can enter the grinding mechanism 30 through the first opening 2112. In this way, the movable door 231 can open the first opening 2112 while removing the support for the beans, thereby reducing the probability of the beans remaining on the movable door 231 after completing the weighing, and reducing the probability of the beans ground by the grinding mechanism 30 being insufficient to affect the quality of the beverage.

[0067] In the embodiments of the present application, the connection relationship between the extension piece 212 and the weight detection piece 22 is not specifically limited. For example, the extension piece 212 can abut against the top of the weight detection piece 22. For another example, the extension piece 212 can be fixedly connected to the weight detection piece 22 by a screw.

[0068] Please refer to Figures 8 to 10 In some embodiments, the weighing tank 211 is provided with two insertion holes 2114 on two sides in the second direction, and the two insertion holes 2114 are in communication with the weighing cavity 2111. The movable door 231 is provided with two connection holes 2311 on two ends in the second direction, and the two connection holes 2311 correspond to and are in communication with the two insertion holes 2114, respectively. The movable door 231 is further provided with two connection grooves 2312 between the two connection holes 2311 in the second direction. The two connection grooves 2312 are spaced apart in the second direction and correspond to the two connection holes 2311 one by one. When the movable door 231 is at the first angle, each connection groove 2312 can penetrate the bottom of the movable door 231 in the vertical direction. Each connection groove 2312 is in communication with the corresponding connection hole 2311, and the projection area of each connection groove 2312 in the second direction can be greater than the projection area of the corresponding connection hole 2311 in the second direction.

[0069] The opening switch assembly 23 can further include two connection pins 232. The two connection pins 232 correspond to the two connection holes 2311 one by one and correspond to the two connection grooves 2312 one by one, respectively. Each connection pin 232 can include a plug-in part 2321 and a movable part 2322. Each plug-in part 2321 extends in the second direction. Each plug-in part 2321 can pass through the corresponding insertion hole 2114 and connection hole 2311 in the second direction, and each plug-in part 2321 can be rotationally fitted with the inner wall of the corresponding insertion hole 2114. The movable part 2322 can be fixedly connected to one end of the corresponding plug-in part 2321 facing the other plug-in part 2321, and the movable part 2322 can extend in the second direction. Each plug-in part 2321 is connected with a plurality of movable parts 2322, and the plurality of movable parts 2322 located on the same plug-in part 2321 can be spaced apart in the direction surrounding the plug-in part 2321. Each movable part 2322 can be partially accommodated in the corresponding connection hole 2311, and the remaining part enters the corresponding connection groove 2312. Each movable part 2322 is fixedly connected with a buckle 2323 on the end of the movable part 2322 in the second direction away from the plug-in part 2321. The side wall of each connection groove 2312 in the second direction away from the other connection groove 2312 is an abutting wall 2313, and each buckle 2323 abuts against the corresponding abutting wall 2313, thereby limiting the movement of the corresponding connection pin 232 in the second direction in the direction of stretching out of the connection hole 2311.

[0070] It can be understood that each connecting pin 232 is rotationally fitted with the inner wall of the corresponding insertion hole 2114, so that the connecting pin 232 can rotate relative to the weighing tank 211, and the movable door 231 connected with the connecting pin 232 can rotate relative to the weighing tank 211. In this way, through the connection of the two connecting pins 232 and the corresponding insertion holes 2114, the relative rotation connection between the movable door 231 and the weighing tank 211 can be achieved.

[0071] In the embodiments of the present application, the connection relationship between the connecting pin 232 and the corresponding connecting hole 2311 is not specifically limited. For example, the insertion part 2321 of the connecting pin 232 can be interference fitted with the corresponding connecting hole 2311.

[0072] It can be understood that the connecting pin 232 can be made of a material with deformation function. When the weighing assembly 21 is assembled, the worker first presses the movable part 2322 of each connecting pin 232, so that the plurality of movable parts 2322 of the same connecting pin 232 are close to each other, so that the plurality of buckles 2323 are close to each other, and then the worker can pass the connecting pin 232 through the insertion hole 2114 and insert it into the connecting hole 2311. After the plurality of movable parts 2322 of the same connecting pin 232 enter the connecting hole 2311, they can be away from each other under the action of their own elastic force, so that the plurality of buckles 2323 abut against the inner wall of the connecting hole 2311; after the plurality of buckles 2323 enter the connecting slot 2312, the plurality of movable parts 2322 can be further away from each other under the action of their own elastic force, so that the plurality of buckles 2323 are further away from each other, so that the projection of each buckle 2323 in the second direction coincides with the projection of the corresponding abutment wall 2313 in the second direction. At this time, when the connecting pin 232 is moved in the direction of stretching out of the connecting hole 2311 of the weighing tank 211 under the action of external force, each buckle 2323 can abut against the corresponding abutment wall 2313 to limit the movement of the connecting pin 232, thereby maintaining the connection between the movable door 231 and the weighing tank 211.

[0073] In the embodiments of the present application, the material of the connecting pin 232 is not specifically limited. For example, the connecting pin 232 can be, but is not limited to, a plastic material.

[0074] In some embodiments, each of the insertion portions 2321 is provided with a positioning slot 234 opening towards one end of the corresponding connection slot 2312 in the second direction. The opening switch assembly 23 can further include two elastic members 233 corresponding to the two connection pins 232. One end of each of the elastic members 233 is accommodated in the corresponding positioning slot 234, and the other end is in abutment with the inner wall of the corresponding connection slot 2312. Each of the elastic members 233 can be elastically deformed after compression and generate an elastic force, and can drive the corresponding connection pin 232 to move in the direction of stretching out of the weighing tank 211 by the elastic force, and keep the tendency of moving in the direction of stretching out of the weighing tank 211.

[0075] It can be understood that each of the elastic members 233 can drive the corresponding insertion portion 2321 to keep the tendency of moving in the direction of stretching out of the weighing tank 211, thereby avoiding the situation that the connection pin 232 completely enters the connection hole 2311 and the connection slot 2312, and avoiding the situation that the connection pin 232 falls off from the corresponding insertion hole 2114, thereby affecting the connection between the movable door 231 and the weighing tank 211.

[0076] After each of the connection pins 232 passes through the corresponding connection hole 2311 and the insertion hole 2114, one end of the connection pin 232 stretches out of the weighing tank 211 from the insertion hole 2114 and keeps outside the weighing tank 211.

[0077] In the embodiments of the present application, the type of the elastic member 233 is not specifically limited. For example, the elastic member 233 can be, but is not limited to, a spring.

[0078] In some embodiments, the driving assembly 24 can include a movable driving member 241 and a gear set.

[0079] The movable driving member 241 is a driving member with a rotating driving function. The movable driving member 241 is in communication connection with the processor 1031. The movable driving member 241 can be fixedly installed on the extension portion and located at some of the extension portion in the second direction. The gear set can include a plurality of gears, one of the plurality of gears of the gear set is fixedly connected with one of the connection pins 232 in a coaxial manner, and another of the plurality of gears is fixedly connected with the movable driving member 241; and each of the plurality of gears is in meshing engagement with at least one adjacent gear. The movable driving member 241 can drive the gear connected with the movable driving member 241 to rotate when the movable driving member 241 works, so as to synchronously rotate the gear set; the gear connected with the connection pin 232 can synchronously rotate the connection pin 232 and the movable door 231. In this way, the processor 1031 can control the rotation of the movable door 231 by controlling the work of the movable driving member 241.

[0080] In the embodiments of the present application, the type of the movable driving member 241 is not specifically limited. For example, the movable driving member 241 can be, but is not limited to, a motor.

[0081] In embodiments of the present application, the number of gears in the gear set is not specifically limited.

[0082] For example, as shown in FIG. 2, the gear set can include a first gear 242 and a second gear 243. The first gear 242 can be fixedly connected coaxially with a connecting pin 232. The second gear 243 can be fixedly connected with the movable driving member 241. The first gear 242 is engaged with the second gear 243. The movable driving member 241 can drive the second gear 243 to rotate, so that the first gear 242 is synchronously rotated, thereby synchronously rotating the movable door 231. Figure 7

[0083] In some embodiments, the bean bin mechanism 10 can include a receiving assembly 11, a screw rod 12, and a transmission driving member 13.

[0084] The receiving assembly 11 can receive bean materials in the vertical direction. The receiving assembly 11 is provided with a transmission cavity 14 extending in the first direction. The receiving assembly 11 is provided with a transmission feed port 1111, which is in communication with the top of the transmission cavity 14. The transmission feed port 1111 can allow the bean materials received by the receiving assembly 11 to enter the transmission cavity 14. The transmission cavity 14 can be in communication with the second docking port 1121, and the transmission cavity 14 can be in communication with the weighing cavity 2111 through the second docking port 1121. In the first direction, the second docking port 1121 is spaced apart from the transmission feed port 1111.

[0085] The screw rod 12 can be received in the transmission cavity 14, and the screw rod 12 can be rotatably connected to the receiving assembly 11. The screw rod 12 can extend in the first direction. The transmission driving member 13 can be fixedly installed on the outside of the receiving assembly 11, and can be fixedly connected with the screw rod 12. The transmission driving member 13 has a rotating driving function. The transmission driving member 13 can be in communication with the processor 1031. The processor 1031 can control the transmission driving member 13 to work after determining the preparation information of the beverage required by the user through the operation panel 1032. The transmission driving member 13 can drive the screw rod 12 to rotate, thereby driving the bean materials in the transmission cavity 14 to move, so that the bean materials move in the direction of the second docking port 1121 along the transmission feed port 1111, and the bean materials enter the weighing cavity 2111 through the second docking port 1121.

[0086] The processor 1031 can control the transmission driving member 13 to stop working when the weight of the bean materials in the weighing cavity 2111 determined by the weight detection member 22 reaches the weight of the bean materials corresponding to the preparation information, thereby stopping the movement of the bean materials in the transmission cavity 14, and preventing the bean materials from entering the weighing cavity 2111.

[0087] ​It can be understood that the cooperation of the transmission driver 13, the screw rod 12 and the transmission cavity 14 can realize the control of the beans entering the weighing cavity 2111. The processor 1031 can control the transmission driver 13 to stop working when it is determined that the beans in the weighing cavity 2111 meet the amount required for beverage making, so as to stop the feeding of the beans to the weighing cavity 2111. In this way, the probability that part of the beans in the transmission cavity 14 enter the bean grinding mechanism 30 simultaneously when the movable door 231 rotates to make the beans in the weighing cavity 2111 enter the bean grinding mechanism 30 can be avoided; the situation that the amount of beans is too much can be reduced, and the situation that the quality of the beverage is poor due to the excessive amount of beans can be reduced. The quality of the beverage can be improved, and the user experience can be improved.

[0088] In the embodiments of the present application, the type of the transmission driver 13 is not specifically limited. For example, the transmission driver can be, but is not limited to, a motor.

[0089] It can be understood that the screw rod 12 can be rotatably connected to the receiving assembly 11 through a rotating connecting piece. In the embodiments of the present application, the type of the rotating connecting piece is not specifically limited. For example, the rotating connecting piece can be, but is not limited to, a bearing, a pin shaft or a hinge.

[0090] In some embodiments, the receiving assembly 11 can include a feeding hopper 111 and an adapter seat 112. The feeding hopper 111 can include a receiving part 1112 and a transmission part 1113. A receiving groove 1114 can be formed on the receiving part 1112, the receiving groove 1114 is a groove, and a transmission feeding port 1111 can be formed on the bottom wall of the receiving groove 1114. The receiving groove 1114 can accommodate the beans, so as to realize the receiving of the beans by the receiving assembly 11. The transmission feeding port 1111 is in communication with the receiving groove 1114, and the beans in the receiving groove 1114 can enter the transmission cavity 14 through the transmission feeding port 1111. The transmission part 1113 can be fixedly connected to the bottom of the receiving part 1112. The transmission cavity 14 can include a first cavity 141 and a second cavity 142 which are in communication. The first cavity 141 can be formed in the transmission part 1113 and penetrates one side of the transmission part 1113 in a first direction; the transmission driver 13 can be located on the other side of the transmission part 1113 in the first direction. At least part of the structure of the screw rod 12 is accommodated in the first cavity 141.

[0091] The adapter seat 112 can be fixedly connected to the transmission part 1113 and can be located on the side of the transmission part 1113 which is penetrated by the first cavity 141. The second cavity 142 can be formed in the adapter seat 112, and at least part of the structure of the screw rod 12 is accommodated in the second cavity 142. A second feeding port is formed on the bottom of the adapter seat 112 in the vertical direction, and the second feeding port is in communication with the second cavity 142.

[0092] It can be understood that the screw rod 12 can drive the beans in the transmission cavity 14 to move from the first cavity 141 to the second cavity 142 when the screw rod 12 rotates. The beans in the second cavity 142 can enter the weighing cavity 2111 through the second inlet under the action of gravity.

[0093] After the user performs the specified operation on the operation panel 1032 to determine the beverage production information, the processor 1031 can control the movable driving member 241 to work, and the movable driving member 241 drives the movable door 231 to rotate, so that the movable door 231 rotates to the first angle.

[0094] Then the processor 1031 can control the transmission driving member 13 to work, and the transmission driving member 13 drives the screw rod 12 to rotate, so that the beans in the transmission cavity 14 move to the direction close to the second interface 1121, and enter the weighing cavity 2111 through the second interface 1121, and then are received on the movable door 231. The weight of the beans on the movable door 231 increases, and the weight detecting member 22 can detect the weight change of the extension member 212, so as to realize the detection of the weight of the beans received on the movable door 231, and output the corresponding detection information to the processor 1031. The processor 1031 can determine whether the weight of the beans on the movable door 231 corresponds to the production information according to the detection information, and control the transmission driving member 13 to stop working when it is determined that the weight of the beans corresponds to the production information, so as to stop the feeding of the beans.

[0095] Then the processor 1031 can control the movable driving member 241 to work, and the movable driving member 241 drives the movable door 231 to rotate from the first angle to the second angle, so that the first opening 2112 is opened, and the beans received on the movable door 231 can enter the grinding mechanism 30 through the first opening 2112 and the bean feeding inlet 33. The processor 1031 can control the grinding mechanism 30 to work, so that the grinding mechanism 30 grinds the beans to generate powder. The processor 1031 can detect the working state of the grinding motor 31, and controls the grinding mechanism 30 to stop working when it is determined that all the beans have been ground. The grinding mechanism 30 can transmit the powder to the extraction device 102, and the processor 1031 can control the extraction device 102 to work according to the production information determined by the user, so that the extraction device 102 extracts the powder to obtain the beverage corresponding to the production information.

[0096] It can be understood that, by weighing the beans by the weighing mechanism 20, the beverage machine 100 can make the weight of the beans entering the bean bin mechanism 10 for grinding correspond to the beverage making information confirmed by the user. Compared with determining the amount of beans by the working time of the bean bin mechanism 10 and other factors, the scheme of weighing the beans first and then grinding the beans in the embodiments of the present application can improve the accuracy of the amount of beans, thereby reducing the probability that the powder produced by the grinding mechanism 30 deviates from the powder required by the user when making the beverage. In this way, the quality of the beverage made by the beverage machine 100 can be improved, and the user experience can be improved.

[0097] At the same time, the beverage machine 100 can stop the rotation of the screw rod 12 when it is determined that the weight of the beans in the weighing cavity 2111 corresponds to the making information, thereby stopping the feeding of the beans and reducing the probability that the weight of the beans entering the grinding mechanism 30 exceeds the weight corresponding to the making information, thereby improving the quality of the beverage and improving the user experience.

[0098] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
