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

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

The extraction device 102 can extract the received powder material and generate liquid. A user can receive the liquid from a liquid outlet (not shown in the figure) of the extraction device 102.

[0033] In the 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. The beverage machine 100 can be a coffee machine, and the extraction device 102 of the beverage machine 100 can extract the powder material and obtain coffee liquid.

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

[0036] In some embodiments, the beverage machine 100 can further include a housing (not shown in the figure). 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.

[0037] In some embodiments, the beverage machine 100 can further include a control device 103. The control device 103 can include a processor 1031 and a control panel 1032. The processor 1031 can be in communication connection with the control panel 1032 and in communication connection with the bean grinding device 101 and the extraction device 102. The control panel 1032 can be fixedly installed on the housing. The control panel 1032 can be in communication connection with the bean grinding device 101. A worker can control the work of the bean grinding device 101 and the extraction device 102 by performing corresponding operations on the control panel 1032.

[0038] For example, the user can control the bean grinder 101 to start or stop grinding the bean material by the processor 1031 and control the extraction device 102 to start or stop extracting the powder material by the processor 1031 to generate liquid by performing corresponding operations on the control panel 1032.

[0039] In embodiments of the present application, the manner of the communication connection is not specifically limited.

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

[0040] In embodiments of the present application, the operation performed by the user on the control panel 1032 is not specifically limited. For example, a plurality of physical buttons or virtual buttons displayed by an image can be arranged on the operation panel, and the user can click the corresponding button on the control panel 1032 to make the bean grinder 101 and / or the extraction device 102 work or stop working. For another example, the user can slide a corresponding pattern on the control panel 1032 by a finger or a tool adapted to the control panel 1032 to make the bean grinder 101 and / or the extraction device 102 work or stop working.

[0041] In embodiments of the present application, the control panel 1032 can adopt a control panel 1032 commonly used in the related field, which will not be described here.

[0042] Please refer to Figure 2 and Figure 3 In embodiments of the present application, the height direction of the bean grinder 101 can be defined as the vertical direction. For example, the vertical direction can be the Z direction and the opposite direction thereof as shown in Figure 2 and Figure 3 .

[0043] In some embodiments, the bean grinder 101 can include a bean bin mechanism 10, a bin door mechanism 20, a driving mechanism 30, and a bean grinding mechanism 40. The bean bin mechanism 10, the bin door mechanism 20, and the bean grinding mechanism 40 can be arranged in the vertical direction according to the direction from top to bottom.

[0044] The bean bin mechanism 10 can accommodate the bean material. A first feeding port 111 can be arranged on the bean bin mechanism 10, and the first feeding port 111 penetrates the bean bin mechanism 10 along the vertical direction. The first feeding port 111 can be used for the bean material to pass through. The bean material passing through the first feeding port 111 can enter the bin door mechanism 20 and then enter the bean grinding mechanism 40 through the bin door mechanism 20. The bean grinding mechanism 40 can grind the bean material entering the bean grinding mechanism 40 to generate powder material. The bean grinding mechanism 40 can be connected and communicated with the extraction device 102, and the bean grinding mechanism 40 can output the generated powder material to the extraction device 102.

[0045] Please refer to Figure 4 and Figure 5 The door mechanism 20 can include a rotating seat 21, a linkage assembly 22, and a plurality of door bodies 23. The rotating seat 21 can rotate relative to the bean bin mechanism 10. The rotating seat 21 is provided with a first through opening 211, which penetrates the rotating seat 21 in the vertical direction and is arranged corresponding to the first feeding opening 111. The linkage assembly 22 can be arranged on the side of the rotating seat 21 facing the bean bin mechanism 10, and the plurality of door bodies 23 can be arranged on the side of the rotating seat 21 facing the bean bin mechanism 10. The plurality of door bodies 23 are located between the first feeding opening 111 and the first through opening 211 and are arranged corresponding to the first feeding opening 111 and the first through opening 211 in the vertical direction. The plurality of door bodies 23 can be arranged in a direction around the rotation center axis of the rotating seat 21. Each of the plurality of door bodies 23 is connected with the linkage assembly 22 and is rotatably connected with the rotating seat 21 through the linkage assembly 22. When the rotating seat 21 rotates relative to the bean bin mechanism 10, the linkage assembly 22 can move synchronously, thereby causing the plurality of door bodies 23 to rotate synchronously, and the rotation center axis of each door body 23 is parallel to the rotation center axis of the rotating seat 21. Each door body 23 includes an abutting end 231. When the plurality of door bodies 23 rotate synchronously, the plurality of abutting ends 231 can approach or move away from each other; when the plurality of abutting ends 231 approach and abut each other, each door body 23 is attached to the adjacent door body 23, and the abutting ends 231 of the plurality of door bodies 23 abut each other, thereby achieving the shielding of the first feeding opening 111; when the plurality of abutting ends 231 move away from each other, the plurality of door bodies 23 unshield the first feeding opening 111, so that the first feeding opening 111 is communicated with the first through opening 211.

[0046] The driving mechanism 30 can be located on the side of the bean bin mechanism 10 facing the bean grinding mechanism 40 in the vertical direction. The driving mechanism 30 can be connected with the rotating seat 21 and drive the rotating seat 21 to rotate.

[0047] It can be understood that the rotation of the rotating seat 21 can drive the plurality of door bodies 23 to approach or move away synchronously, thereby causing the plurality of door bodies 23 to shield or open the first feeding opening 111, achieving the opening or closing of the first feeding opening 111.

[0048] When the first feeding port 111 is opened, the beans in the bean bin mechanism 10 can pass through the first feeding port 111, the space surrounded by the plurality of door bodies 23, and the first passing port 211, and finally enter the bean grinding mechanism 40. The bean grinding mechanism 40 can grind the beans entering the bean grinding mechanism 40 into powder, and transmit the powder to the extraction device 102. When the extraction device 102 extracts the powder, the plurality of door bodies 23 can be rotated to close the first feeding port 111, so as to block the water vapor generated in the process of the extraction device 102 extracting the powder, reduce the transmission of the water vapor to the bean bin mechanism 10 through the first feeding port 111, increase the probability of the bean bin mechanism 10, reduce the humidity of the beans in the bean bin, and improve the taste of the liquid generated by the extraction device 102.

[0049] It can be understood that the bottom of the bean bin mechanism 10 is the part of the bean bin mechanism 10 close to the bean grinding mechanism 40, and the top is the part of the bean bin mechanism 10 away from the bean grinding mechanism 40. Similarly, the bottom of the bin door mechanism 20 is the part of the bin door mechanism 20 close to the bean grinding mechanism 40, and the top is the part of the bin door mechanism 20 away from the bean grinding mechanism 40.

[0050] In some embodiments, the first receiving groove 2131 is formed on the side of the rotating seat 21 close to the bean bin mechanism 10. The linkage assembly 22 and the plurality of door bodies 23 are accommodated in the first receiving groove 2131. The first receiving groove 2131 is in communication with the first passing port 211. When the first feeding port 111 is opened, the first receiving groove 2131 can be in communication with the first feeding port 111 to realize the communication between the first feeding port 111 and the first passing port 211.

[0051] Please refer to Figure 6 In some embodiments, the bean bin mechanism 10 can include a feeding hopper 11, a limiting plate 12, a first mounting seat 13, a first convex ring 14, and a second convex ring 15. The feeding hopper 11 is provided with a feeding groove 112, which can accommodate beans. The top of the feeding hopper 11 is open, and the opening of the feeding hopper 11 is in communication with the feeding groove 112. The bottom wall of the feeding groove 112 is correspondingly arranged at the opening of the feeding hopper 11. The first feeding port 111 is formed on the bottom wall of the feeding groove 112. In the vertical direction, the height of the position where the first feeding port 111 is formed on the bottom wall of the feeding groove 112 is lower than the height of the edge position of the bottom wall of the feeding groove 112. In the direction of the edge of the feeding groove 112 towards the first feeding port 111, the bottom wall of the feeding groove 112 is inclined, and the height of the position close to the first feeding port 111 is lower than the height of the position away from the first feeding port 111. In this way, the first feeding port 111 is located at the bottom end of the feeding hopper 11.

[0052] The circumferential wall of the feeding groove 112 is fixedly connected with a connecting seat 113, which is located in the feeding groove 112. In the vertical direction, the connecting seat 113 is spaced apart from the bottom wall of the feeding groove 112. The limiting plate 12 is detachably connected to the connecting seat 113. The limiting plate 12 installed on the connecting seat 113 is located in the feeding groove 112 and corresponds to the first feeding port 111. The first projection (not shown in the figure) of the limiting plate 12 in the vertical direction can coincide with the second projection (not shown in the figure) of the first feeding port 111 in the vertical direction, and the area of the first projection is greater than that of the second projection. The spacing between the limiting plate 12 and the bottom wall of the feeding groove 112 at the edge of the first feeding port 111 in the vertical direction can be greater than the length, width or thickness of the bean material, and can be less than twice the length, width or thickness of the bean material.

[0053] The first mounting seat 13 is fixedly connected to the bottom of the feeding hopper 11 and extends in the vertical direction towards the bean grinding mechanism 40. The first mounting seat 13 is arranged to avoid the bin door mechanism 20. The first mounting seat 13 is spaced apart from the first protruding ring 14 and spaced apart from the second protruding ring 15. The first mounting seat 13 is hollow, and the driving mechanism 30 is at least partially accommodated in the first mounting seat 13.

[0054] The first protruding ring 14 and the second protruding ring 15 are both protrudingly arranged on the bottom of the feeding hopper 11 and extend in the vertical direction towards the bean grinding mechanism 40. The second protruding ring 15 is arranged around the first feeding port 111, and the third projection (not shown in the figure) of the second protruding ring 15 in the vertical direction coincides with the second projection. The first protruding ring 14 is arranged around the second protruding ring 15, and the second protruding ring 15 is spaced apart from the first protruding ring 14. The fourth projection (not shown in the figure) of the first protruding ring 14 in the vertical direction coincides with the third projection. The first protruding ring 14 can be arranged on the side of the rotating seat 21 facing the bean bin mechanism 10, and the inner wall of the first protruding ring 14 can be in rotating cooperation with the rotating seat 21, so that the rotating seat 21 can rotate relative to the bean bin mechanism 10. The second protruding ring 15 cooperates with the part of the bottom of the feeding hopper 11 close to the first feeding port 111 to form an annular clamping space 151. The first sealing ring 152 is accommodated in the clamping space 151, and the side of the first sealing ring 152 facing the bean grinding mechanism 40 can abut against the plurality of door bodies 23.

[0055] In the embodiments of the present application, the fixed connection and the fixed installation are not specifically limited in the fixed manner. For example, the fixed manner can include, but is not limited to, bolt fixing, adhesive fixing, buckle fixing, welding fixing and one-piece fixing.

[0056] In the embodiments of the present application, the detachable connection is not specifically limited in the connection manner. For example, the connection manner of the detachable connection can include, but is not limited to, buckle connection, threaded connection and magnetic attraction connection.

[0057] It can be understood that the spacing of the limiting plate 12 and the part on the bottom wall of the feed groove 112 at the edge of the first feed port 111 in the vertical direction can block the beans stacked in the feed groove 112, so that the beans located away from the bottom wall of the feed groove 112 cannot approach and pass through the first feed port 111, limiting the number of beans passing through the first feed port 111; at the same time, it can also block other foreign matters from approaching and passing through the first feed port 111. In this way, the probability of bean blockage in the first feed port 111 can be reduced, and the probability of foreign matters entering the bean grinding mechanism 40 through the first feed port 111 can be reduced, the stability of the beverage machine 100 during operation can be improved, the service life of the beverage machine 100 can be increased, and by setting the limiting plate 12, it can effectively prevent the user's fingers from misoperation into the bean grinding mechanism 40, and prevent accidents from happening.

[0058] It can be understood that, as shown in Figure 4 When the abutting ends 231 of the plurality of door bodies 23 abut to close the first feed port 111, the first sealing ring 152 can close the gap between each door body 23 and the bean bin mechanism 10. In this way, when the first feed port 111 is closed, the plurality of door bodies 23 block the first feed port 111 from the vertical direction, and the first sealing ring 152 closes the gap between the door body 23 and the bean bin mechanism 10 from the direction perpendicular to the vertical direction, which can achieve the isolation of the feed groove 112 bin door mechanism 20; while the plurality of door bodies 23 block the water vapor in the vertical direction, the first sealing ring 152 can reduce the probability of water vapor entering the first feed port 111 from the gap between the door body 23 and the bean bin mechanism 10, and improve the effect of isolating water vapor.

[0059] It can be understood that the bean bin mechanism 10 can be connected with the bin door mechanism 20 in a detachable manner by covering the cover of the rotating seat 21 with the first protruding ring 14. In this way, the convenience of disassembling the bean bin mechanism 10 and the bin door mechanism 20 for the staff or user can be improved, and the staff or user can conveniently overhaul the internal structure of the beverage machine 100.

[0060] It can be understood that when the first protruding ring 14 covers the rotating seat 21, the first protruding ring 14 can be in communication with the first receiving groove 2131.

[0061] In some embodiments, the driving mechanism 30 can include a driving member 31 and a triggering assembly 32. The driving member 31 can be located at one side of the door mechanism 20 in any direction perpendicular to the vertical direction. The driving member 31 can be in communication with the processor 1031. The triggering assembly 32 is connected with the driving member 31. The triggering assembly 32 can include at least one triggering unit 321. The driving member 31 can actuate the triggering unit 321. The triggering unit 321 can control the state change of the first feeding port 111 by the actuation, wherein the state change of the first feeding port 111 can include opening and closing. Thus, when the triggering unit 321 is actuated, the first feeding port can be opened or closed.

[0062] It can be understood that the user can operate the control panel 1032, and the processor 1031 can control the driving member 31 to work in the open door state or the closed door state according to the user's operation. The driving member 31 working in the open door state can actuate the triggering unit 321 to open the first feeding port 111; the driving member 31 working in the closed door state can actuate the triggering unit 321 to close the first feeding port 111.

[0063] In the embodiments of the present application, the number of the triggering unit 321 is not specifically limited. The following embodiments can be exemplified according to the number of the triggering unit 321 being two.

[0064] In some embodiments, the triggering assembly 32 can further include a transmission member 322. The transmission member 322 can be fixedly connected with the mover of the driving member 31, and the driving member 31 can drive the transmission member 322 to move. The transmission member 322 can be connected with the rotating seat 21, and the movement of the transmission member 322 can drive the rotating seat 21 to rotate synchronously. The transmission member 322 has a first position (not shown in the figure) and a second position (not shown in the figure). When the transmission member 322 is in the first position, the plurality of door bodies 23 are away from each other, and the first feeding port 111 is opened. When the transmission member 322 is in the second position, the plurality of door bodies 23 are close to each other, and the first feeding port 111 is closed.

[0065] It can be understood that the user can operate the control panel 1032, and the processor 1031 can control the driving member 31 to work in the open door state or the closed door state according to the user's operation. When the driving member 31 works in the open door state, the driving member 31 can drive the transmission member 322 to move to the first position, so as to open the first feeding port 111. When the driving member 31 works in the closed door state, the driving member 31 can drive the transmission member 322 to move to the second position, so as to close the first feeding port 111.

[0066] In some embodiments, the circumferential wall of the rotating seat 21 can be fixedly connected with an arc-shaped rack 212. The transmission member 322 can be a gear, and the driving member 31 can drive the transmission member 322 to rotate. The transmission member 322 can include a gear portion and a rotating shaft portion. The gear portion of the transmission member 322 can be located on the side of the first mounting seat 13 facing the grinding mechanism 40. The gear portion of the transmission member 322 can be engaged with the arc-shaped rack 212. The diameter of the gear portion of the transmission member 322 is greater than the inner diameter of the first mounting seat 13 and less than the diameter of the rotating shaft portion. The rotating shaft portion of the transmission member 322 is located on the side of the gear portion facing the hopper 11 and is accommodated in the first mounting seat 13. The rotating shaft portion of the transmission member 322 can be rotationally fitted with the inner wall of the first mounting seat 13, so that the transmission member 322 can rotate relative to the bean bin mechanism 10. The axial direction of the transmission member 322 coincides with the vertical direction.

[0067] It can be understood that the driving member 31 can be an electric member having a function of driving the rotation of the component. In the embodiments of the present application, the type of the driving member 31 is not specifically limited. For example, the driving member 31 can be, but is not limited to, a motor.

[0068] It can be understood that when the driving member 31 drives the transmission member 322 to rotate, the arc-shaped rack 212 and the rotating seat 21 can be synchronously rotated, thereby realizing the automatic rotation of the plurality of door bodies 23, so that the first feeding port 111 can be automatically opened or closed.

[0069] Please refer to Figure 7 In some embodiments, the driving mechanism 30 can further include a housing 33, a cam member 323, and a plurality of trigger switches 3212.

[0070] As shown in Figure 2 and Figure 3 The housing 33 is hollow, and at least part of the structure of the driving member 31 can be accommodated in the housing 33. The housing 33 can include a first housing 331 and a second housing 332. The first housing 331 and the second housing 332 can be arranged in the vertical direction, and the first housing 331 is located on the side of the second housing 332 close to the bean bin mechanism 10 in the vertical direction. The first housing 331 and the second housing 332 are detachably connected. The driving member 31 can be fixedly connected with the inner wall of the second housing 332. One side of the grinding mechanism 40 can be fixedly connected with a receiving seat 41. The receiving seat 41 can receive the second housing 332, and the second housing 332 is detachably connected to the receiving seat 41.

[0071] The trigger assembly 32 can further include a cam member 323. The cam member 323 can include a connecting portion 3231 and a wheel body portion 3232. The connecting portion 3231 extends in the vertical direction, and the connecting portion 3231 can be fixedly connected and coaxial with the mover of the driving member 31. The connecting portion 3231 can be provided with the first shell 331 at a position close to the bean bin mechanism 10 in the vertical direction, and the connecting portion 3231 can be fixedly connected and coaxial with the transmission member 322 at a position extending out of the machine shell 33, so as to achieve the connection between the cam member 323 and the driving member 31. The wheel body portion 3232 can be fixedly connected to the peripheral portion of the connecting portion 3231. The wheel body portion 3232 is arranged around the connecting portion 3231, and the wheel body portion 3232 is located on the side of the connecting portion 3231 away from the bean bin mechanism 10 in the vertical direction. The driving member 31 can drive the cam member 323 to rotate, so as to synchronously rotate the transmission member 322, the arc-shaped rack 212 and the rotating seat 21.

[0072] Please refer to Figure 8 and Figure 9 Each trigger unit 321 can include a trigger portion 3211 and a trigger switch 3212. The trigger portion 3211 can be fixedly connected to the peripheral portion of the wheel body portion 3232. The trigger switch 3212 is located on the side of the peripheral wall of the wheel body portion 3232 facing the other side, and the trigger switch 3212 is arranged in a spaced manner with the wheel body portion 3232. The trigger switch 3212 is used to abut against the corresponding trigger portion 3211. The trigger switch 3212 is in communication connection with the processor 1031, so as to realize the communication connection with the driving member 31 through the processor 1031. When the driving member 31 drives the cam member 323 and the transmission member 322 to rotate, the trigger portion 3211 can synchronously rotate, so that the trigger portion 3211 can be close to and abut against the corresponding trigger switch 3212. When the number of the trigger units 321 is multiple, the number of the trigger portions 3211 and the number of the trigger switches 3212 are also multiple. The multiple trigger portions 3211 can be arranged in a spaced manner in the direction around the wheel body portion 3232. The multiple trigger switches 3212 can be arranged in a spaced manner in the direction around the wheel body portion 3232.

[0073] When the transmission member 322 is in the first position, at least one trigger portion 3211 abuts against one trigger switch 3212; when the transmission member 322 is in the second position, at least one trigger portion 3211 abuts against another trigger switch 3212. Each trigger switch 3212 can output a trigger signal to the processor 1031 after abutting against the corresponding trigger portion 3211, and the processor 1031 can receive the trigger signal and control the driving member 31 to stop working, so as to stop the rotation of the wheel body portion 3232, and thus stop the rotation of the rotating seat 21 and each door body 23.

[0074] It is understandable that the user can perform an opening operation on the control panel 1032, causing the control panel 1032 to output an opening signal to the processor 1031. For example... Figure 8 As shown, after receiving the door opening signal, the processor 1031 can control the drive unit 31 to operate in the open state, that is, the mover of the drive unit 31 rotates along the first circumferential direction. The drive unit 31 can drive the cam unit 323 and the transmission unit 322 to rotate along the first circumferential direction, so that the abutment ends 231 of the multiple door bodies 23 move away from each other. At least one trigger part 3211 on the cam unit 323 can approach the corresponding trigger switch 3212 during the rotation of the cam unit 323 along the first circumferential direction. When the transmission unit 322 rotates to the first position, at least one trigger part 3211 abuts against the corresponding trigger switch 3212, so that the corresponding trigger switch 3212 outputs a trigger signal to the processor 1031; at this time, the multiple door bodies 23 do not block the first feed port 111, and the first feed port 111 is opened. After receiving the trigger signal, the processor 1031 controls the drive unit 31 to stop working, so that the rotating seat 21 and the multiple door bodies 23 all stop rotating; at this time, the first feed port 111 can remain open.

[0075] Similarly, the user can perform a door-closing operation by controlling the control panel 1032, causing the control panel 1032 to output a door-closing signal to the processor 1031. After receiving the door-closing signal, the processor 1031 can control the drive unit 31 to operate in the closed state, that is, the mover of the drive unit 31 rotates along the second circumferential direction. Figure 9 As shown, the drive member 31 can drive the cam member 323 and the transmission member 322 to rotate along the second circumferential direction, causing the abutment ends 231 of the multiple door bodies 23 to approach each other. At least one trigger part 3211 on the cam member 323 can approach the corresponding trigger switch 3212 during the rotation of the cam member 323 along the second circumferential direction. When the transmission member 322 rotates to the second position, at least one trigger part 3211 abuts against the corresponding trigger switch 3212, causing the corresponding trigger switch 3212 to output a trigger signal to the processor 1031; at this time, the abutment ends 231 of the multiple door bodies 23 are in contact with each other, and the first feed port 111 is closed. After receiving the trigger signal, the processor 1031 controls the drive member 31 to stop working, so that the rotating seat 21 and the multiple door bodies 23 all stop rotating; at this time, the first feed port 111 can remain closed.

[0076] Therefore, by triggering the abutment between the trigger portion 3211 and the corresponding trigger switch 3212, the rotation angle of the cam member 323 and the transmission member 322 can be limited, and the rotation angle of the rotating seat 21 and the plurality of door bodies 23 can be limited, thereby reducing the probability that the rotating seat 21 and the plurality of door bodies 23 continue to rotate or remain in a rotating state after the first feed inlet 111 is opened or closed, reducing the probability of damage to the bin door mechanism 20, and increasing the service life of the bean grinding device 101.

[0077] It can be understood that the driving member 31 can drive the transmission member 322 to rotate, so that the transmission member 322 is angularly displaced, and the transmission member 322 reciprocates between the first position and the second position.

[0078] It can be understood that the first circumferential direction and the second circumferential direction are opposite circumferential directions. In the first circumferential direction and the second circumferential direction, one direction is clockwise and the other direction is counterclockwise.

[0079] It can be understood that the number of trigger portions 3211 can be two, and the number of trigger switches 3212 can be two, one-to-one correspondence between the two trigger portions 3211 and the two trigger switches 3212; in the direction of rotation of the cam member 323, the two trigger portions 3211 are located between the two trigger switches 3212.

[0080] In the embodiments of the present application, the type of the trigger switch 3212 is not specifically limited. For example, the trigger switch 3212 can be, but is not limited to, a micro switch, a travel switch, or a Hall switch, etc. For example, the trigger switch 3212 can be a micro switch, the trigger switch 3212 is provided with a trigger spring for abutting with the trigger portion 3211 and movable, when the trigger portion 3211 abuts on the trigger spring of the trigger switch 3212 and moves the trigger spring, the trigger switch 3212 is triggered, so as to output a trigger signal to the processor 1031.

[0081] In the embodiments of the present application, the connection relationship of the trigger switch 3212 in the shell 33 is not specifically limited. For example, the trigger switch 3212 can be fixedly installed on the stator of the driving member 31. For example, the trigger switch 3212 can be fixedly connected with the inner wall of the first shell 331.

[0082] For example, the side of the connecting part 3231 facing away from the bean bin mechanism 10 can be provided with a slot, the cross section of the driver 31 mover can be in a non-circular pattern, the slot of the connecting part 3231 can be adapted to the shape of the driver 31 mover, and the driver 31 mover can be inserted into the slot of the connecting part 3231 to achieve the connection and coaxiality of the driver 31 and the cam member 323. At the same time, the side of the transmission member 322 facing away from the bean bin mechanism 10 can be provided with a slot, the cross section of the side of the connecting part 3231 facing the bean bin mechanism 10 can be in a non-circular pattern, the slot of the transmission member 322 can be adapted to the shape of the side of the connecting part 3231 facing the bean bin mechanism 10, and the connecting part 3231 can be inserted into the slot of the transmission member 322 to achieve the connection and coaxiality of the cam member 323 and the transmission member 322.

[0083] For example, the second shell 332 can be detachably fixed on the receiving seat 41 by a buckle, the buckle on the second shell 332 can pass through the clamping groove on the receiving seat 41 in the vertical direction, and then the second shell 332 is rotated to enable the buckle on the second shell 332 to be clamped with the clamping groove on the receiving seat 41.

[0084] The first shell 331 and the second shell 332 can be detachably connected by a buckle. The first shell 331 can be moved in the vertical direction to approach the second shell 332, so that the buckle on the second shell 332 enters the clamping groove on the first shell 331 to achieve the connection of the first shell 331 and the second shell 332.

[0085] It can be understood that after the shell 33, the driver 31, the trigger switch 3212 and the cam member 323 are assembled, they can be simultaneously installed on the receiving seat 41, and then the transmission member 322 can be sleeved on the connecting part 3231 to achieve the installation of the driving mechanism 30 in the beverage machine 100. When the driving mechanism 30 needs to be repaired, the shell 33 can be rotated and moved to disassemble the driving mechanism 30 from the beverage machine 100 and disassemble the driving mechanism 30, which is convenient for users or workers to repair.

[0086] In some embodiments, the bean grinding device 101 can further include an adjusting mechanism 50. The adjusting mechanism 50 is connected with the bean grinding mechanism 40, and the adjusting mechanism 50 can move to drive part of the structure of the bean grinding mechanism 40 to move, so as to adjust the fineness of the powder produced by the bean grinding device 101.

[0087] For example, the second shell 332 can be detachably fixed on the receiving seat 41 by a buckle, the buckle on the second shell 332 can pass through the clamping groove on the receiving seat 41 in the vertical direction, and then the second shell 332 is rotated to enable the buckle on the second shell 332 to be clamped with the clamping groove on the receiving seat 41. Figure 2As shown, the adjusting mechanism 50 can include a knob member 51 and a gear member 52, which can be coaxially and fixedly connected. The bean bin mechanism 10 can further include a second mounting seat 16, which can be spaced apart from the first mounting seat 13 and can be vertically arranged in the hopper 11. Two ends of the second mounting seat 16 are located in the feeding groove 112 and the side of the bean bin mechanism 10 facing the bean grinding mechanism 40, respectively.

[0088] The knob member 51 can include a knob portion and a shaft portion. The knob portion of the knob member 51 can be located in the feeding groove 112, and the diameter of the knob portion of the knob member 51 can be greater than the inner diameter of the portion of the second mounting seat 16 located in the feeding groove 112. The shaft portion of the knob member 51 can enter the second mounting seat 16 from the feeding groove 112 and be rotationally fitted with the inner wall of the second mounting seat 16, so that the knob member 51 can rotate relative to the bean bin mechanism 10.

[0089] The gear member 52 can include a gear portion and a shaft portion. The gear portion of the gear member 52 can be located at the side of the second mounting seat 16 facing the bean grinding mechanism 40. The diameter of the gear portion of the transmission member 322 can be greater than the inner diameter of the first mounting seat 13. The shaft portion of the gear member 52 is located at the side of the gear portion facing the hopper 11 and is accommodated in the second mounting seat 16. The shaft portion of the gear member 52 can be rotationally fitted with the inner wall of the second mounting seat 16, so that the gear member 52 can rotate relative to the bean bin mechanism 10. The bean grinding mechanism 40 can be rotationally connected with an adjusting gear 42, and the rotation of the adjusting gear 42 can adjust the fineness of the powder produced by the bean grinding mechanism 40. The gear portion of the gear member 52 can directly engage with the adjusting gear 42 or indirectly engage with the adjusting gear 42 through other gear members. The axial directions of the knob member 51 and the gear member 52 coincide with the vertical direction.

[0090] It can be understood that the rotation of the knob member 51 can drive the rotation of the gear member 52, so that the adjusting gear 42 of the bean grinding mechanism 40 rotates, thereby adjusting the fineness of the powder produced by the bean grinding mechanism 40.

[0091] In the embodiments of the present application, the bean grinding mechanism 40 can adopt the mechanisms commonly used in the related art, and the principles of arranging the adjusting gear 42 on the bean grinding mechanism 40 and adjusting the fineness of the powder produced by the bean grinding mechanism 40 through the rotation of the adjusting gear 42 are all common principles in the related art, which will not be described herein.

[0092] In some embodiments, the bean grinding device 101 can further include a cover plate 60. The cover plate 60 is used to cover the opening of the hopper 11 and the feeding groove 112 and is detachably connected to the top of the hopper 11.

[0093] For example, the cover plate 60 can be inserted into the feed slot 112 in the vertical direction to cover the feed slot 112 and the opening of the feed hopper 11. The peripheral wall of the cover plate 60 can be sleeved with a second sealing ring 61, which can be attached to the side wall of the feed slot 112 to limit the relative movement between the cover plate 60 and the feed hopper 11 in the vertical direction through friction.

[0094] It can be understood that when the cover plate 60 is covered on the feed hopper 11, it can block foreign matter from entering the feed slot 112, reducing the probability of foreign matter blocking the first feed port 111 and affecting the operation of the bean grinding mechanism 40.

[0095] When the plurality of door bodies 23 cover the first feed port 111, the plurality of door bodies 23 and the first sealing ring 152 can close the feed slot 112 from the bottom of the feed slot 112, and the cover plate 60 can close the feed slot 112 from the top of the feed slot 112, so that the feed slot 112 can form a closed space when the extraction device 102 is working, reducing the probability of water vapor entering the feed slot 112 and affecting the quality of the bean material.

[0096] Please refer to Figure 10 In some embodiments, each door body 23 can further include a first connecting end 232 and a second connecting end 233, and the first connecting end 232, the second connecting end 233, and the abutting end 231 are spaced apart in a direction perpendicular to the vertical direction. Each door body 23 further includes a first abutting wall 234 and a second abutting wall 235, the first abutting wall 234 can be located between the first connecting end 232 and the abutting end 231, and the second abutting wall 235 can be located between the second connecting end 233 and the abutting end 231. The end of the first abutting wall 234 close to the abutting end 231 can be connected to the end of the second abutting wall 235 close to the abutting end 231. The first abutting end 231 of each door body 23 can abut and fit with the second abutting wall 235 of the adjacent door body 23, so that each door body 23 fits with the adjacent door body 23; at this time, the abutting ends 231 of the plurality of door bodies 23 abut with each other, thereby completely covering the first feed port 111.

[0097] It can be understood that the first abutting wall 234 and the second abutting wall 235 can be arc-shaped walls that match each other. One of the first abutting wall 234 and the second abutting wall 235 is a convex arc surface, and the other is a concave arc surface. In the embodiments of the present application, the first abutting wall 234 and the second abutting wall 235 are not specifically limited to be convex arc surfaces or concave arc surfaces. For example, as shown in the drawings, the first abutting wall 234 is a concave arc surface, and the second abutting wall 235 is a convex arc surface.

[0098] In some embodiments, the linkage assembly 22 can include a positioning ring 221 and a plurality of connecting arms 222. The positioning ring 221 can be provided with a second through hole 2211 in the middle portion thereof, which is arranged in correspondence with the first through hole 211 and is in communication with the first through hole 211 to achieve communication with the first feeding port 111. The positioning ring 221 is detachably connected to the bean bin mechanism 10 and can be kept relatively fixed with the feeding hopper 11. The positioning ring 221 is located on the side of the plurality of door bodies 23 away from the feeding hopper 11 and is rotatably connected to the first connecting end 232 of each door body 23. The second through hole 2211 is located between the first through hole 211 and the first feeding port 111 in the vertical direction.

[0099] The plurality of connecting arms 222 correspond to the plurality of door bodies 23 one by one. The plurality of connecting arms 222 are arranged around the positioning ring 221. Each connecting arm 222 includes a first end and a second end arranged at intervals. The first end of each connecting arm 222 is rotatably and detachably connected to the rotating seat 21, and the second end is rotatably connected to the second connecting end 233 of the corresponding door body 23. The plurality of connecting arms 222 are located on the side of the plurality of door bodies 23 away from the feeding hopper 11. The rotation center axis of each connecting arm 222 is parallel to the rotation center axis of the rotating seat 21.

[0100] It can be understood that when the rotating seat 21 rotates, the positioning ring 221 and the bean bin mechanism 10 can be kept relatively fixed and thus do not rotate, and each connecting arm 222 can rotate synchronously in the first receiving groove 2131. Since the rotation center axis of each connecting arm 222 is different from the rotation center axis of the rotating seat 21, each connecting arm 222 can rotate relative to the rotating seat 21 while rotating relative to the positioning ring 221. The rotation of each connecting arm 222 can drive the corresponding door body 23 to rotate synchronously, so that the plurality of door bodies 23 can approach or move away from each other by synchronous rotation, achieving closing or opening of the first feeding port 111.

[0101] It can be understood that the positioning ring 221 and the plurality of connecting arms 222 can be located at the same height in the vertical direction, and the peripheral portion of the positioning ring 221 can be provided with a plurality of notches, each of which can be used for the corresponding connecting arm 222 to enter during rotation, so that the positioning ring 221 avoids each connecting arm 222.

[0102] In some embodiments, the bottom of the feeding hopper 11 can be fixedly connected with a plurality of first positioning cylinders (not shown in the figure). The plurality of first positioning cylinders are arranged at intervals in the direction perpendicular to the vertical direction and extend in the direction close to the bean grinding mechanism 40 in the vertical direction.

[0103] The positioning ring 221 can be fixedly connected with a plurality of positioning columns 2212. The plurality of positioning columns 2212 are arranged in a direction perpendicular to the vertical direction and extend in the vertical direction towards the bean bin mechanism 10. The plurality of positioning columns 2212 correspond to the plurality of first positioning cylinders one by one, and the plurality of positioning columns 2212 and the plurality of first positioning cylinders all avoid the plurality of door bodies 23. Each positioning column 2212 can be inserted into the corresponding first positioning cylinder and fixedly connected with the corresponding first positioning cylinder to achieve the detachable connection between the positioning ring 221 and the feeding hopper 11.

[0104] In some embodiments, the positioning ring 221 can be fixedly connected with a plurality of first pivots 2213, which are arranged in a direction surrounding the second through hole 2211. The plurality of first pivots 2213 all extend in the vertical direction towards the bean bin mechanism 10. The plurality of first pivots 2213 correspond to the plurality of door bodies 23 one by one. Each first pivot 2213 is arranged in the vertical direction through the first connecting end 232 of the corresponding door body 23 to pivotally connect the corresponding door body 23, thereby achieving the rotatable connection between the positioning ring 221 and the plurality of door bodies 23.

[0105] Each connecting arm 222 is fixedly connected with a second pivot 2221 and a third pivot 2222. The second pivot 2221 is located at the first end of the connecting arm 222, and the third pivot 2222 is located at the second end of the connecting arm 222. The second pivot 2221 extends in the vertical direction away from the bean bin mechanism 10, and the third pivot 2222 extends in the vertical direction towards the bean bin mechanism 10. Each second pivot 2221 can be arranged in the vertical direction through the bottom wall of the first receiving groove 2131 to pivotally connect the rotating seat 21, thereby achieving the rotatable connection between each connecting arm 222 and the rotating seat 21. Each third pivot 2222 can be arranged in the vertical direction through the second connecting end 233 of the corresponding door body 23 to pivotally connect the corresponding door body 23, thereby achieving the rotatable connection between each connecting arm 222 and the corresponding door body 23.

[0106] In some embodiments, the rotating seat 21 can include a first sub-seat 213 and a second sub-seat 214. The first sub-seat 213 and the second sub-seat 214 are arranged adjacent to each other in the vertical direction, and the first sub-seat 213 is located on the side of the second sub-seat 214 away from the bean grinding mechanism 40. The first sub-seat 213 and the second sub-seat 214 are both circular ring-shaped seat bodies, and the diameter of the first sub-seat 213 is greater than the diameter of the second sub-seat 214. The first through hole 211 penetrates the first sub-seat 213 and the second sub-seat 214 in the vertical direction. The first receiving groove 2131 is arranged on the side of the first sub-seat 213 facing the bean bin mechanism 10. The arc-shaped rack 212 is fixedly connected to the peripheral portion of the second sub-seat 214.

[0107] As Figure 3 and Figure 6As shown, the door body 23 can further include a door mounting seat 24. The bottom of the hopper 11 can be fixedly connected with a plurality of second positioning cylinders 114. The plurality of second positioning cylinders 114 are spaced apart in a direction perpendicular to the vertical direction and extend in the vertical direction towards the bean grinding mechanism 40. The door mounting seat 24 can be fixedly connected to one end of the plurality of second positioning columns 2212 away from the hopper 11. The door mounting seat 24 can be provided with a mounting groove 241 on a side facing the hopper 11. The mounting groove 241 can include a first region 2411 and a second region 2412. The second region 2412 is located on one side of the first region 2411 and communicates with the first region 2411. A third through hole 242 is formed in the middle of the bottom wall of the first region 2411 and penetrates the door mounting seat 24 in the vertical direction. The third through hole 242 communicates with the first region 2411. The second sub-seat 214 is accommodated in the first region 2411 and rotationally fitted with the inner wall of the first region 2411. The first mounting seat 13 enters the first region 2411 from the end facing the bean grinding mechanism 40. The gear portion of the transmission member 322 is accommodated in the second region 2412 and can rotate in the second region 2412. When the second sub-seat 214 is located in the first region 2411, the third through hole 242 can communicate with the first through hole 211 to achieve communication with the first feeding port 111.

[0108] A boss 243 is arranged on the inner wall of the first region 2411. The boss 243 receives the second sub-seat 214 from the bottom and rotationally fits with the second sub-seat 214. The boss 243 is in the form of an incomplete ring. The two ends of the boss 243 are located on both sides of the position where the first region 2411 and the second region 2412 communicate, and the distance between the two ends of the boss 243 in the circumferential direction is greater than the length of the arc-shaped rack 212 in the circumferential direction. The transmission member 322 located in the second region 2412 can enter the position where the first region 2411 and the second region 2412 communicate and mesh with the arc-shaped rack 212.

[0109] It can be understood that the rotatable connection between the transmission member 322 and the bottom wall of the second region 2412 can be the same as or similar to the rotatable connection between the connecting arm 222 and the bottom wall of the first accommodation groove 2131, which will not be described here.

[0110] It can be understood that the two ends of the boss 243 can limit the movement distance of the arc-shaped rack 212 by abutting against the arc-shaped rack 212, so as to limit the rotation angle of the rotating seat 21. In this way, the situation that the door body 23 is damaged due to the continuous rotation of the rotating seat 21 after the door body 23 is rotated to the position can be reduced, and the service life of the bean grinding device 101 and the beverage machine 100 can be increased.

[0111] The door mounting seat 24 can be connected to the rotating seat 21, thereby achieving the connection of the linkage assembly 22 and the plurality of door bodies 23. In this way, the connection of the door mounting seat 24 and the bean bin mechanism 10 can achieve the connection of the door mechanism 20 and the bean bin mechanism 10. During the assembly of the beverage machine 100, the door mechanism 20 and the bean bin mechanism 10 can be connected first, and then the door mechanism 20 and the bean bin mechanism 10 can be installed in the shell synchronously, thereby improving the convenience of the assembly of the beverage machine 100.

[0112] For example, the door mounting seat 24 can be fixedly connected to the plurality of second positioning cylinders 114 through the screws that are arranged in the door mounting seat 24 and are threadedly connected to the plurality of second positioning cylinders 114. The disassembly of the screws can achieve the separation of the bean bin mechanism 10 and the door mechanism 20, thereby facilitating the maintenance of the bean bin mechanism 10 and the door mechanism 20 by the staff or the user.

[0113] In the embodiments of the present application, the connection relationship between the boss 243 and the door mounting seat 24 is not specifically limited. For example, the boss 243 can be formed by the partial structure of the door mounting seat 24 being bent and extending into the first area 2411 after the door mounting seat 24 is processed by pressing. For another example, the boss 243 can be an independent structure that is fixedly connected to the side wall and / or the bottom wall of the first area 2411.

[0114] In some embodiments, as shown in Figure 6 The door mounting seat 24 is provided with a through slot 244 at a position corresponding to the transmission member 322. The through slot 244 is in communication with the second area 2412, and the through slot 244 is arranged on the side of the door mounting seat 24 away from the bean bin mechanism 10. The end of the connecting portion 3231 toward the bean bin mechanism 10 can pass through the through slot 244 in the vertical direction and be fixedly connected to the transmission member 322.

[0115] It can be understood that the through slot 244 can be arranged in correspondence with and in communication with the insertion slot on the transmission member 322, and the connecting portion 3231 can pass through the through slot 244 and the insertion slot on the transmission member 322 synchronously to achieve the connection with the transmission member 322.

[0116] Please refer to Figure 11 In some embodiments, the side of the bean grinding mechanism 40 toward the bean bin mechanism 10 is provided with a second feeding port 43. The second feeding port 43 is arranged in correspondence with and in communication with the third through port 242. The bean grinding mechanism 40 grinds the bean material entering the bean grinding mechanism 40 through the second feeding port 43 to generate powder.

[0117] The receiving ring 44 can be fixedly connected to the bean grinding mechanism 40. The receiving ring 44 is located on the side of the bean grinding mechanism 40 close to the bean bin mechanism 10. The receiving ring 44 can be arranged around the second feeding port 43 and communicate with the second feeding port 43. The second sub-base 214 is provided with a second receiving groove 2141 on the side facing the bean grinding mechanism 40. The second receiving groove 2141 communicates with the first passing port 211 and the first area 2411. The receiving ring 44 can pass through the third passing port 242 and the first area 2411 and enter the second receiving groove 2141. The receiving ring 44 can abut against the top wall of the second receiving groove 2141 to achieve the receiving of the rotating base 21. The receiving ring 44 can be rotatably connected with the bottom wall and the peripheral wall of the second receiving groove 2141 to achieve the relative rotation between the rotating base 21 and the receiving ring 44.

[0118] It can be understood that when the first feeding port 111 is opened, the beans in the feeding groove 112 can pass through the first feeding port 111, the space surrounded by the plurality of door bodies 23, the second passing port 2211, the first passing port 211, the receiving ring 44 and the second feeding port 43 in the vertical direction from top to bottom, and then enter the bean grinding mechanism 40 for grinding processing. The third passing port 242 can achieve the avoidance of the bin door mounting base 24 to the receiving ring 44. The receiving ring 44 can pass through the receiving rotating base 21 to achieve the receiving of the bean bin mechanism 10 and the bin door mechanism 20. At the same time, the receiving ring 44 can guide the beans passing through the first passing port 211 to flow to the second feeding port 43, thereby reducing the probability of the beans scattering in the shell and failing to enter the bean grinding mechanism 40, and reducing the waste of the beans.

[0119] The receiving of the receiving ring 44 to the bin door mechanism 20 can achieve the separable connection between the bean grinding mechanism 40 and the bin door mechanism 20. The worker can lift the bin door mechanism 20 to achieve the separation of the bin door mechanism 20 and the bean grinding mechanism 40, which can facilitate the worker to maintain the bin door mechanism 20 and the bean grinding mechanism 40 respectively, and can improve the convenience of assembling the beverage machine 100.

[0120] In other embodiments, the receiving ring 44 can be sleeved on the bean grinding mechanism 40 and can rotate relative to the bean grinding mechanism 40. When the bin door mechanism 20 is moved away from the receiving ring 44, the worker can take off the receiving ring 44 from the bean grinding mechanism 40.

[0121] Through the bean grinding device 101 and the beverage machine 100 provided by the embodiments of the present application, when the plurality of door bodies 23 do not block the first feeding port 111, i.e. the first feeding port 111 is opened, the beans in the feeding groove 112 can pass through the first feeding port 111, the space surrounded by the plurality of door bodies 23, the second passing port 2211, the first passing port 211, the receiving ring 44 and the second feeding port 43, and then enter the bean grinding mechanism 40.

[0122] After the beans enter the grinding mechanism 40, the user can perform a door closing operation on the control panel 1032, and the control panel 1032 outputs a door closing signal to the processor 1031. The processor 1031 can control the driving member 31 to work in a door closing state, so that the cam member 323 and the transmission member 322 rotate. The arc-shaped rack 212 and the rotating seat 21 rotate synchronously with the transmission member 322. The rotation of the rotating seat 21 can drive the plurality of connecting arms 222 to rotate relative to the rotating seat 21 and the bean bin mechanism 10, thereby driving the plurality of door bodies 23 to rotate synchronously. The abutting ends 231 of the plurality of door bodies 23 move close to each other. When the plurality of door bodies 23 rotate to the abutting ends 231 abutting each other, and the first abutting wall 234 of each door body 23 abuts against the second abutting wall 235 of the adjacent door body 23, the plurality of door bodies 23 block the first feeding port 111, and the first feeding port 111 is closed. At this time, at least one abutting end 231 abuts against the corresponding trigger switch 3212, and the corresponding trigger switch 3212 outputs a trigger signal to the processor 1031. The processor 1031 controls the driving member 31 to stop working.

[0123] After the user performs the door closing operation on the control panel 1032, the user can continue to perform a designated operation on the control panel 1032, so that the grinding mechanism 40 can grind the beans entering the grinding mechanism 40 to generate powder, and the powder is transmitted to the extraction device 102. The extraction device 102 can extract the received powder to obtain liquid.

[0124] When it is necessary to supplement the beans to the grinding mechanism 40 again, the user can perform a door opening operation on the control panel 1032, and the control panel outputs a door opening signal to the processor 1031. The processor 1031 can control the driving member 31 to work in a door opening state, so that the cam member 323 and the first gear rotate. The arc-shaped rack 212 and the rotating seat 21 rotate synchronously with the transmission member 322. The rotation of the rotating seat 21 can drive the plurality of connecting arms 222 to rotate relative to the rotating seat 21 and the bean bin mechanism 10, thereby driving the plurality of door bodies 23 to rotate synchronously. The abutting ends 231 of the plurality of door bodies 23 move away from each other. When the plurality of door bodies 23 rotate to each door body 23 not blocking the first feeding port 111, the first feeding port 111 is opened. At this time, at least one abutting end 231 abuts against the corresponding trigger switch 3212, and the corresponding trigger switch 3212 outputs a trigger signal to the processor 1031. The processor 1031 controls the driving member 31 to stop working.

[0125] It can be understood that when the extraction device 102 is working, the plurality of doors 23 abutting each other can block the water vapor from passing through the first feed port 111 in the vertical direction, and the first sealing ring 152 abutting the plurality of doors 23 can block the water vapor from passing through the first feed port 111 in other directions perpendicular to the vertical direction, so that the feed tank 112 is sealed, the probability of water vapor entering the feed tank 112 is reduced, the probability of the bean material being damp is reduced, the taste of the liquid produced by the beverage machine 100 through the bean material is improved, and the storage time of the bean material in the feed tank 112 is increased. In addition, the beverage machine can be manually closed when it is in standby or power-off for a short period of time, and the first feed port 111 is closed. In addition, the bean bin cover plate has the sealing of the second sealing ring 61, so that the bean bin mechanism 10 also forms a closed space, which prevents the dampening of the bean material in the bean bin and eliminates the cumbersome operation of manually removing the bean material.

[0126] The user can operate the control panel 1032 to automatically drive the driving member 31, automatically rotate the rotating seat 21, and automatically open and close the first feed port 111. At the same time, the plurality of trigger switches 3212 and the plurality of trigger portions 3211 can cooperate to enable the driving member 31 to stop working in time when the first feed port 111 is opened and closed, thereby reducing the probability of damage to the bean grinding device 101 due to excessive rotation of the transmission member 31, the cam member 323, and the rotating seat 21, and increasing the service life of the bean grinding device 101.

[0127] At the same time, the bean bin mechanism 10 can be fixed relative to the bin door mechanism 20, and the bin door mechanism 20 can be detachably received on the bean grinding mechanism 40. The combination mechanism formed by the bean bin mechanism 10 and the bin door mechanism 20 can be detachably connected with the bean grinding mechanism 40. The worker or user can remove the combination mechanism from the bean grinding mechanism 40 to separately maintain the combination mechanism and the bean grinding mechanism 40, thereby improving the convenience of maintaining the bean bin mechanism 10, the bin door mechanism 20, and the bean grinding mechanism 40. At the same time, the worker or user can place the combination mechanism on the receiving ring 44 to connect the combination mechanism and the bean grinding mechanism 40, thereby improving the convenience of assembling the beverage machine 100.

[0128] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application should be considered in all aspects 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 range of equivalents of the elements of the claims are intended to be embraced in the present application.
