[0031] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0032] The embodiment of the present application provides a bean bin installation structure, which can be used in a coffee machine, but is not limited to a coffee machine, and can also be used in other bean grinding devices. When the bean bin installation structure is used in a coffee machine, the bean bin 1 is used to hold coffee beans. The following description takes the bean bin 1 being used to hold coffee beans as an example.

[0033] like Figure 1 As shown, the bean bin installation structure includes: a bean bin assembly and a fixing bracket 4. The bean bin assembly includes a bean bin body and a valve 3. The bean bin body includes a bean bin 1 and a bean bin seat 2. The bean bin 1 is provided with a lower bean opening 11, as shown in FIG. Figure 3 and Figure 5 The bean bin seat 2 is configured to support the bean bin 1. The valve 3 is rotatably mounted on the bean bin seat 2 and configured to open or close the lower bean opening 11. The valve 3 is provided with a first tooth portion 313.

[0034] The fixed bracket 4 is configured to support the bean bin assembly and is rotatably matched with the bean bin seat 2. The fixed bracket 4 is provided with a second tooth portion 41. The second tooth portion 41 is configured to be meshed with the first tooth portion 313, so that the valve 3 can rotate relative to the bean bin seat 2 between an open position for opening the lower bean opening 11 and a closed position for closing the lower bean opening 11 during the rotation of the bean bin seat 2 relative to the fixed bracket 4.

[0035] The bean silo installation structure provided in the embodiment of the present application includes a bean silo assembly and a fixed bracket 4. The bean silo assembly includes a bean silo 1, a bean silo seat 2 and a valve 3. The bean silo 1 is used to hold coffee beans. The bean silo 1 is provided with a lower bean opening 11 for the coffee beans to fall and discharge. The discharged coffee beans can be ground into coffee powder. The valve 3 is used to control the opening and closing of the lower bean opening 11. The bean silo seat 2 is used to support the bean silo 1 and serve as a mounting carrier for the valve 3. The fixed bracket 4 can support the bean silo assembly to ensure the stability and reliability of the bean silo assembly during use. The bean silo seat 2 and the fixed bracket 4 can be provided with a material passing port 25 (such as Figure 5 and Figure 6 As shown in FIG. 1 , the feed port 25 can be connected to the lower bean port 11 when the lower bean port 11 is opened. The feed port 25 can be connected to the grinding device. When the valve 3 opens the lower bean port 11, the coffee beans can pass through the lower bean port 11 and the feed port 25 into the grinding device and be ground into coffee powder. When the bean bin assembly needs to be removed, the bean bin assembly is removed from the fixing bracket 4, and the valve 3 can close the lower bean port 11 to prevent the coffee beans in the bean bin 1 from spilling out of the lower bean port 11.

[0036] The valve 3 is rotatably mounted on the bean silo seat 2 and can rotate relative to the bean silo seat 2. The bean silo 1 can be detachably connected to the bean silo seat 2, and the bean silo seat 2 can be rotatably matched with the fixed bracket 4, so that the bean silo assembly can rotate relative to the fixed bracket 4 as a whole. The valve 3 is provided with a first tooth portion 313, and the fixed bracket 4 is provided with a second tooth portion 41 for matching with the first tooth portion 313. The second tooth portion 41 is equivalent to a part of the sun gear, and the first tooth portion 313 is equivalent to a part of the planetary gear. The planetary gear also rotates during the process of orbiting around the sun gear. Therefore, the valve 3 can also rotate relative to the bean silo seat 2 (rotation process) during the process of rotating with the bean silo seat 2 relative to the fixed bracket 4 (revolution process).

[0037] When it is necessary to grind coffee beans, the bean bin assembly is placed on the fixed bracket 4. By rotating the bean bin assembly, the first tooth portion 313 can rotate under the action of the second tooth portion 41, thereby driving the valve 3 to rotate from the closed position to the open position (such as Figure 5 and Figure 6 ), the coffee beans can then fall downward into the grinding device.

[0038] When beans need to be added to the bean bin 1, the bean bin assembly can be rotated in the reverse direction to make the first tooth portion 313 rotate in the reverse direction under the action of the second tooth portion 41, thereby driving the valve 3 to rotate from the open position to the closed position (such as Figure 3 and Figure 4 Then, remove the bean bin assembly from the fixed bracket 4, and add beans into the bean bin 1.

[0039] Therefore, the bean silo installation structure provided in the embodiment of the present application can integrate the fixing / removing process of the bean silo assembly with the opening and closing operation of the valve 3, which is beneficial to avoid the situation where the user forgets to close the valve 3 when removing the bean silo assembly, resulting in spilling beans, and the operation is relatively convenient; and there is no need to additionally set up a complex linkage mechanism to realize the rotation of the valve 3, but the rotation of the valve 3 can be realized through the cooperation of the first tooth portion 313 on the valve 3 and the second tooth portion 41 on the fixed bracket 4, which is beneficial to simplify the structure and reduce costs.

[0040] In other embodiments, the bean silo body may not include the bean silo seat, and a structure corresponding to the function of the bean silo seat may be provided at the bottom of the bean silo (it may also be understood that the bean silo and the bean silo seat are integrally formed) to achieve the coordination relationship between the bean silo body, the valve and the fixed bracket.

[0041] In some exemplary embodiments, the valve 3 includes: a plurality of valve plates 31 distributed along the circumference of the lower bean inlet 11, such as Figure 4 and Figure 6 Each valve plate 31 is provided with a first tooth portion 313. The fixed bracket 4 is provided with a plurality of second tooth portions 41, as shown in FIG. Figure 4 and Figure 6The plurality of second tooth portions 41 are arranged correspondingly to the plurality of first tooth portions 313 .

[0042] The plurality of valve plates 31 may be evenly distributed along the circumference of the bean lower opening 11. The number of the valve plates 31 may be, but is not limited to, two.

[0043] This solution is conducive to reducing the area of ​​a single valve plate 31, so as to reduce the demand for activity space of a single valve plate 31, facilitate the flexible rotation of the valve plate 31 in the bean silo seat 2, and also help to reduce the rotation range of the bean silo assembly to improve the convenience of operation.

[0044] In some exemplary embodiments, the valve plate 31 includes a rotating portion 311 and a shielding portion 312 connected to each other. Figure 2 , Figure 4 and Figure 6 The rotating part 311 is rotatably connected to the bean bin seat 2 and is provided with a first tooth part 313 , and the shielding part 312 is configured to shield a part of the lower bean opening 11 .

[0045] Based on the valve 3 rotating to the closed position, the plurality of shielding parts 312 shield the bean outlet 11 together to close the bean outlet 11. Figure 4 shown.

[0046] Based on the valve 3 rotating to the open position, the plurality of shielding portions 312 are located on the circumferential outer side of the bean lowering opening 11 to open the bean lowering opening 11. Figure 6 shown.

[0047] The rotating portion 311 is located radially outside the valve plate 31, and is mainly used to realize the rotatable connection between the valve plate 31 and the bean bin seat 2 and the meshing of the first tooth portion 313 and the second tooth portion 41 of the fixed bracket 4. The shielding portion 312 is located radially inside the valve plate 31, and is mainly used to cooperate with the lower bean opening 11 to realize the function of the valve 3 opening or closing the lower bean opening 11.

[0048] In some exemplary embodiments, each shielding portion 312 is provided with a slot 314 and a protrusion 315. Figure 2 The card slot 314 is configured to engage with the card protrusion 315 of the adjacent valve plate 31, as shown in FIG. Figure 4 As shown, the valve 3 is self-locking when it is rotated to the closed position. This is beneficial to improve the stability and reliability of the valve 3 when it is in the closed position.

[0049] The card slot 314 may be arranged on the radial inner side of the shielding portion 312, and the card protrusion 315 may be arranged on the radial outer side of the shielding portion 312. Figure 4 Alternatively, the locking groove 314 is arranged on the radially outer side of the shielding portion 312 , and the locking protrusion 315 is arranged on the radially inner side of the shielding portion 312 .

[0050] In some exemplary embodiments, the fixing bracket 4 is arranged to be sleeved on the outside of the bean silo seat 2, and the second tooth portion 41 is arranged on the inner side wall of the fixing bracket 4. The bean silo seat 2 is provided with a notch 21 for avoiding the first tooth portion 313, such as Figure 1 The first tooth portion 313 is disposed in the notch 21 and meshes with the second tooth portion 41. Figure 4 and Figure 6 shown.

[0051] For a solution in which the valve 3 includes a plurality of valve plates 31 , the bean silo seat 2 may be provided with a plurality of notches 21 accordingly to ensure that the first tooth portion 313 of each valve plate 31 can mesh with the corresponding second tooth portion 41 .

[0052] Of course, the bean silo seat 2 may also not be provided with the notch 21 , the side wall of the bean silo seat 2 may be shorter or have no side wall, and the first tooth portion 313 directly protrudes from the bean silo seat 2 and meshes with the second tooth portion 41 .

[0053] In some exemplary embodiments, the inner side wall of the fixing bracket 4 is provided with a slide groove 42, such as Figure 1 , Figure 4 and Figure 6 As shown. The first tooth portion 313 is arranged to be inserted into the fixed bracket 4 along the slide groove 42, and the slide groove 42 is arranged adjacent to the second tooth portion 41. The slide groove 42 can only be used for partial embedding of the first tooth portion 313. The second tooth portion 41 can also only be partially matched with the first tooth portion 313. The first tooth portion 313 can also only be partially matched with the second tooth portion 41.

[0054] In this way, when fixing the bean bin assembly, the first tooth portion 313 of the bean bin assembly needs to be aligned with the slide groove 42, and then the bean bin assembly is placed downward on the fixing bracket 4. At this time, the first tooth portion 313 is located in the slide groove 42, adjacent to the second tooth portion 41, but not meshed. When the bean bin assembly is rotated, the first tooth portion 313 rotates in the direction of the second tooth portion 41 to mesh with the second tooth portion 41. Continuing to rotate the bean bin assembly can rotate the valve 3 relative to the bean bin seat 2, thereby opening the lower bean opening 11.

[0055] When removing the bean bin assembly, the bean bin assembly is rotated in the opposite direction, and the valve 3 rotates in the opposite direction relative to the bean bin seat 2, thereby closing the lower bean opening 11. When the first tooth portion 313 rotates to the slide groove 42, it separates from the second tooth portion 41, and the bean bin assembly can be smoothly removed from the fixed bracket 4.

[0056] Therefore, the provision of the slide groove 42 is conducive to improving the operational convenience of the bean bin assembly removal and fixing process.

[0057] In some exemplary embodiments, the bean bin assembly further includes: an elastic member, such as Figure 1 , Figure 4 and Figure 6As shown, it cooperates with the valve 3 and the bean bin seat 2 and is configured to assist in driving the valve 3 to rotate toward the closed position.

[0058] When the valve 3 is in the closed position, the resetting elastic force of the elastic member is limited and cannot overcome the meshing force between the first tooth portion 313 and the second tooth portion 41 and drive the bean bin assembly as a whole to rotate relative to the fixed bracket 4, so that the valve 3 can be kept in the closed position. During the opening process, the resetting elastic force of the elastic member can play an auxiliary role, which is conducive to reducing the operating force applied by the user to rotate the bean bin assembly, thereby facilitating the user's operating convenience.

[0059] In the case where the valve 3 includes a plurality of valve plates 31 , the number of the elastic members may be equal to and correspond to the number of the valve plates 31 , so as to ensure that each valve plate 31 can be subjected to the auxiliary force of the elastic member during the closing process.

[0060] In some exemplary embodiments, the bean silo seat 2 is provided with a rotating shaft 22 and a positioning shaft 23. Figure 4 and Figure 6 As shown. The valve 3 is provided with an axial hole 317, as shown Figure 2 The rotating shaft 22 is inserted into the shaft hole 317 and can rotate relative to the shaft hole 317 to realize the rotatable connection between the valve 3 and the bean bin seat 2.

[0061] In some exemplary embodiments, the valve 3 is provided with a first limiting portion, the bean hopper seat 2 is provided with a second limiting portion, and the elastic member includes a torsion spring 5, such as Figure 1 , Figure 4 and Figure 6 One torsion arm of the torsion spring 5 is limited at the first limiting portion, and the other torsion arm of the torsion spring 5 is limited at the second limiting portion.

[0062] The structure of the first limiting portion is not limited, for example, it can be an L-shaped limiting protrusion 316 (such as Figure 1 , Figure 4 and Figure 6 As shown), hooking a torsion arm of the torsion spring 5 to achieve limiting; it can also be a socket for partially inserting a torsion arm of the torsion spring 5 to achieve limiting.

[0063] Similarly, the structure of the second limiting portion is not limited, for example, it can also be a gap 24 between the protrusion and the inner wall of the bean silo seat 2 (such as Figure 4 and Figure 6 As shown), clamping the other torsion arm of the torsion spring 5 to achieve limiting; it can also be a socket for inserting the other torsion arm of the torsion spring 5 to achieve limiting; it can also be an L-shaped limiting protrusion to hook the other torsion arm of the torsion spring 5 to achieve limiting.

[0064] The first limiting portion can be arranged on the rotating portion 311 of the valve plate 31 , so that the rotation torque applied by the torsion spring 5 to the valve plate 31 is relatively small, which is conducive to the valve plate 31 to remain in the closed position under the meshing force of the first tooth portion 313 and the second tooth portion 41 .

[0065] In some exemplary embodiments, the torsion spring 5 is sleeved on the positioning shaft 23, which is beneficial to improve the position stability and reliability of the torsion spring 5. The positioning shaft 23 and the rotating shaft 22 can be spaced apart along the circumference of the bean silo seat 2, and are close to each other, and are not easy to interfere with the valve 3.

[0066] For a solution in which the valve 3 includes a plurality of valve plates 31 , the number of the rotating shafts 22 may be equal to and correspond to the number of the valve plates 31 . The number of the positioning shafts 23 may be equal to and correspond to the number of the torsion springs 5 ​​.

[0067] The embodiment of the present application further provides a coffee machine (not shown in the figure), including the bean bin mounting structure of any one of the above embodiments, and thus has all the above beneficial effects, which will not be repeated here.

[0068] In summary, the bean hopper installation structure and the coffee machine provided in the embodiments of the present application are conducive to preventing the user from forgetting to close the valve when removing the bean hopper assembly, resulting in spilling beans, and have a compact structure and are easy to operate.
