[0031] The specific structure of the embodiments of this application will be described in detail below.

[0032] This application provides a beverage machine. The beverage machine includes, but is not limited to, a coffee machine and a milk tea machine.

[0033] Please see Figure 1 The beverage machine 1000 provided in this application may include a main unit 300, a raw material box 200, and a grinding mechanism 100.

[0034] The main unit 300 is used to make beverages. For example, the main unit 300 can be a coffee machine or a milk tea machine.

[0035] The raw material container 200 is used to store grinding raw materials. The grinding raw materials can be in block or granular form. For example, the grinding raw materials include, but are not limited to, coffee beans.

[0036] The material container 200 has a discharge port (not shown in the figure). The opening shape of the discharge port is, but is not limited to, circular, rectangular, or irregular. The grinding material can be discharged from the material container 200 through the discharge port.

[0037] The ingredient container 200 is detachably disposed relative to the grinding mechanism 100. The ingredient container 200 supplies grinding materials to the grinding mechanism 100. The grinding mechanism 100 grinds the grinding materials supplied by the ingredient container 200 to prepare powdered ingredients. The main unit 300 can brew and extract the powdered ingredients to prepare a beverage.

[0038] For example, the material container 200 can be detachably mounted on the main unit 300. For instance, the connection between the material container 200 and the main unit 300 includes, but is not limited to, screw connections, snap-fit ​​connections, or magnetic connections. The grinding mechanism 100 can also be detachably mounted on the main unit 300. For instance, the connection between the grinding mechanism 100 and the main unit 300 includes, but is not limited to, screw connections, snap-fit ​​connections, or magnetic connections. In other examples, one of the material container 200 and the grinding mechanism 100 can be detachably mounted on the main unit 300, while the other is not detachably mounted on the main unit 300, as long as the material container 200 and the grinding mechanism 100 are relatively detachable.

[0039] The following section will focus on a detailed description of the structure of the grinding mechanism 100.

[0040] Please see Figure 2 and Figure 3 The grinding mechanism 100 includes a first cutter head assembly 10 and a second cutter head assembly 20.

[0041] Please continue reading. Figure 3 and combined Figure 4 The first cutter head assembly 10 includes a first mounting base 11 and a first cutter head 12.

[0042] The material of the first mounting base 11 includes, but is not limited to, metal, plastic, and a combination of the two.

[0043] The first mounting base 11 has an open mounting space on one side, and the first cutter head 12 rotates around the axis of rotation O1 (see reference). Figure 4 It is rotatably mounted in the mounting space of the first mounting base 11.

[0044] For example, the rotatable connection between the first cutter head 12 and the first mounting base 11 includes, but is not limited to, shaft-hole mating.

[0045] The material of the first cutting disc 12 includes, but is not limited to, metal. The shape of the first cutting disc 12 includes, but is not limited to, a circle.

[0046] The second cutter head assembly 20 is detachably connected to the first cutter head assembly 10. This facilitates the disassembly and assembly of the second cutter head assembly 20, enabling cleaning and maintenance of the grinding mechanism 100.

[0047] Please continue reading. Figure 4 The second cutter head assembly 20 includes a second cutter head 22 and an adjusting member 23.

[0048] The material of the second cutter head 22 includes, but is not limited to, metal. The shape of the second cutter head 22 includes, but is not limited to, a circle.

[0049] The second cutter head 22 is disposed opposite to the first cutter head 12 in the extension direction of the rotation axis O1. Specifically, the second cutter head 22 can be located within the mounting space of the first mounting base 11 and disposed opposite to the first cutter head 12 in the extension direction of the rotation axis O1.

[0050] For example, the second cutter head 22 and the first cutter head 12 can be arranged coaxially, for example, their axes are collinear with the rotation axis O1. In this way, the structure is compact and the space occupied by the first cutter head 12 and the second cutter head 22 in the first mounting base 11 can be reduced.

[0051] The second cutter head assembly 20 may have a feed channel. The feed channel may communicate with the discharge port of the material box 200, so that the grinding material discharged from the discharge port may be fed through the feed channel to the space between the second cutter head 22 and the first cutter head 12. In this way, when the first cutter head 12 rotates about the rotation axis O1, the grinding material located between the first cutter head 12 and the second cutter head 22 can be ground into powder, thereby achieving the purpose of grinding.

[0052] The adjusting component 23 is connected to the second cutter head 22 via a transmission. The adjusting component 23 is used to adjust the gap between the second cutter head 22 and the first cutter head 12.

[0053] In this way, by using the adjusting element 23 to adjust the gap between the first cutter head 12 and the second cutter head 22, it is beneficial to adjust the grinding fineness of the grinding mechanism 100 and meet different user needs.

[0054] Please continue reading. Figure 3The first mounting base 11 is provided with a first limiting structure 14, and the second cutter head assembly 20 is provided with a second limiting structure 24. Of course, in other embodiments, the second limiting structure 24 can be provided on the first mounting base 11, and the first limiting structure 14 can be provided on the second cutter head assembly 20, as long as one of the second cutter head assembly 20 and the first mounting base 11 is provided with the first limiting structure 14, and the other of the second cutter head assembly 20 and the first mounting base 11 is provided with the second limiting structure 24.

[0055] Please continue reading. Figure 3 The first limiting structure 14 includes a limiting part 141 and an unlocking part 142 distributed circumferentially on the first mounting base 11.

[0056] When the second limiting structure 24 engages with the limiting part 141, the second cutter head assembly 20 is restricted from separating from the first cutter head assembly 10. When the second limiting structure 24 corresponds to the unlocking part 142, the second cutter head assembly 20 is allowed to separate from the first cutter head assembly 10.

[0057] Specifically, during the assembly of the second cutter head assembly 20, the second limiting structure 24 can be aligned with the unlocking part 142 along the extension direction of the rotation axis O1, and the second cutter head assembly 20 can be placed in the mounting space of the first mounting base 11. Then, along the circumference of the first mounting base 11, the second cutter head assembly 20 and / or the first cutter head assembly 10 can be rotated until the limiting part 141 and the second limiting structure 24 are aligned in the extension direction of the rotation axis O1. With the matching of the limiting positions, the second cutter head assembly 20 and the first cutter head assembly 10 can be assembled together. During the disassembly of the second cutter head assembly 20, the second cutter head assembly 20 and / or the first cutter head assembly 10 can be rotated in the opposite direction until the unlocking part 142 and the second limiting structure 24 are aligned in the extension direction of the rotation axis O1. Then, the second cutter head assembly 20 and / or the first cutter head assembly 10 can be moved away from the first cutter head assembly 10 along the extension direction of the rotation axis O1, thereby separating the first cutter head assembly 10 and the second cutter head assembly 20.

[0058] In this embodiment, a first limiting structure 14 is provided in one of the second cutter head assembly 20 and the first mounting base 11, and a second limiting structure 24 is provided in the other of the second cutter head assembly 20 and the first mounting base 11. The first limiting structure 14 includes a limiting portion 141 and an unlocking portion 142 distributed circumferentially on the first mounting base 11. When the limiting portion 141 cooperates with the second limiting structure 24 to limit the movement, the second cutter head assembly 20 is restricted to separate from the first cutter head assembly 10. When the unlocking portion 142 corresponds to the position of the second limiting structure 24, the second cutter head assembly 20 can be moved away from the first cutter head assembly 10 along the extension direction of the rotation axis O1 and / or the first cutter head assembly 10 can be moved away from the second cutter head assembly 20, thereby separating the first cutter head assembly 10 and the second cutter head assembly 20, thus enabling the detachable assembly of the first cutter head assembly 10 and the second cutter head assembly 20. Therefore, it can be seen that with fewer parts and a simpler structure, the first cutter head assembly 10 and the second cutter head assembly 20 can be easily disassembled and assembled, which helps to improve the disassembly and assembly efficiency of the grinding mechanism 100 and facilitates the daily maintenance of the grinding mechanism 100.

[0059] Furthermore, the reduction in the number of parts used to assemble the first cutter head assembly 10 and the second cutter head assembly 20 helps to reduce the cumulative assembly error of the grinding mechanism 100 and improves the grinding accuracy of the grinding mechanism 100 to at least a certain extent.

[0060] For example, the number of first limiting structures 14 and second limiting structures 24 are the same.

[0061] For example, there are multiple first limiting structures 14 and multiple second limiting structures 24, such as two, three, four, or five. Multiple first limiting structures 14 are spaced apart on the circumference of the first mounting base 11, and correspondingly, multiple second limiting structures 24 are spaced apart on the circumference of the first mounting base 11. This facilitates the use of the limiting cooperation between the multiple first limiting structures 14 and the multiple second limiting structures 24, thereby improving the reliability of the connection between the first cutter head assembly 10 and the second cutter head assembly 20.

[0062] For example, a plurality of first limiting structures 14 are evenly spaced apart in the circumferential direction of the first mounting base 11, and a plurality of second limiting structures 24 are evenly spaced apart in the circumferential direction of the first mounting base 11. In this way, the force exerted on the plurality of first limiting structures 14 and the plurality of second limiting structures 24 in the circumferential direction of the first mounting base 11 is more uniform, thereby further improving the connection reliability between the first cutter head assembly 10 and the second cutter head assembly 20.

[0063] Please refer to some embodiments of this application. Figure 3 and Figure 4The second cutter head assembly 20 also includes a second mounting base 21. An adjusting member 23 is movably disposed on the inner circumference of the second mounting base 21 along the extension direction of the rotation axis O1. A second limiting structure 24 is disposed on the outer circumference of the second mounting base 21. In this way, by providing the second mounting base 21, not only can it support the adjusting member 23 and the second cutter head 22, achieving a modular design and a more compact structure for the second cutter head assembly 20, but the second limiting structure 24 can also be disposed on the second mounting base 21, facilitating the assembly of the second cutter head assembly 20 with the first mounting base 11, thus enabling a detachable connection between the second cutter head assembly 20 and the first cutter head assembly 10. Furthermore, with the adjusting member 23 located on the inner circumference of the second mounting base 21 and the second limiting structure 24 located on the outer circumference of the second mounting base 21, the overall structural layout is reasonable, and the adjusting member 23 and the second limiting structure 24 will not interfere with each other.

[0064] The material of the second mounting base 21 includes, but is not limited to, metal, plastic, or a combination of both. The shape of the second mounting base 21 includes, but is not limited to, an annular frame shape.

[0065] For specific examples, please refer to [link / reference]. Figure 3 The inner circumferential surface of the first mounting base 11 is recessed with a groove 11A. The groove 11A includes a first groove portion 11A1 and a second groove portion 11A2 along the circumferential direction of the first mounting base 11. In the extension direction of the rotation axis O1, the groove wall of the second groove portion 11A2 away from the second cutter head 22 is provided with a notch 1121. The first groove portion 11A1 defines a limiting portion 141. The second groove portion 11A2 and the notch 1121 together define an unlocking portion 142. The second limiting structure 24 is a boss protruding from the outer circumferential surface of the second mounting base 21.

[0066] Specifically, during the assembly of the grinding mechanism 100, the boss can first be moved into the second groove 11A2 through the notch 1121 along the extension direction of the rotation axis O1. Then, along the circumference of the first mounting base 11, the second cutter head assembly 20 and / or the first cutter head assembly 10 are rotated so that the boss moves into the first groove 11A1. At this time, the first groove 11A1 and the boss are matched and limited in the extension direction of the rotation axis O1. At this time, the second mounting base 21 is restricted to separate from the first mounting base 11, and the second cutter head assembly 20 is restricted to separate from the first cutter head assembly 10. During the disassembly of the grinding mechanism 100, the second cutter head assembly 20 and / or the first cutter head assembly 10 can be rotated in the opposite direction until the boss is located in the second groove 11A2. Then, the second cutter head assembly 20 and / or the first cutter head assembly 10 can be moved away from the first cutter head assembly 10 along the extension direction of the rotation axis O1. After the boss disengages from the second groove 11A2 through the notch 1121, the second mounting seat 21 can be separated from the first mounting seat 11, thereby separating the first cutter head assembly 10 and the second cutter head assembly 20.

[0067] As can be seen from the above description, the locking and unlocking method achieved by the groove 11A and the boss is simple in structure, easy to process and manufacture, and easy to disassemble and assemble, which helps to improve the disassembly and assembly efficiency of the grinding mechanism 100 and facilitates the daily maintenance of the grinding mechanism 100.

[0068] For example, the boss and the second mounting base 21 can be integrally molded, which simplifies the processing of both, reduces manufacturing costs, and improves the connection strength between them. In other examples, the boss and the second mounting base 21 can also be connected by means of adhesive bonding, welding, snap-fitting, or screw connection.

[0069] For some specific examples, please refer to [link / reference]. Figure 3 and Figure 4 The first mounting base 11 includes a body 111 and a connecting plate 112.

[0070] The shape of the connecting plate 112 includes, but is not limited to, a flat plate or a curved plate. The connection method between the connecting plate 112 and the body 111 includes, but is not limited to, welding, snap-fitting, screw connection or adhesive bonding.

[0071] The inner circumferential surface of the body 111 is recessed with a groove 1111. In the extension direction of the rotation axis O1, the side wall of the groove 1111 away from the second cutter head 22 is open to form an opening. A notch 1121 is formed on the connecting plate 112, which covers the opening. The connecting plate 112 and the groove 1111 cooperate to define the groove 11A. This facilitates machining the groove 1111 on the body 111 and the notch 1121 on the connecting plate 112. Then, the connecting plate 112 is assembled with the body 111, and the groove 11A is defined by the cooperation of the connecting plate 112 and the groove 1111. This allows the connecting plate 112 to be used as a stop structure for the second limiting structure 24, simplifying the structure, reducing the manufacturing difficulty of the groove 11A, and improving processing efficiency.

[0072] For some specific examples, please refer to Figure 4 and combined Figure 5 The second cutter head assembly 20 also includes a connector 25. The connector 25 may be made of materials including, but not limited to, metal, plastic, or a combination of both.

[0073] The connecting seat 25 and the second mounting seat 21 are floatingly connected along the extension direction of the rotation axis O1. The second mounting seat 21 and the second cutter head 22 are respectively disposed on both sides of the connecting seat 25. Specifically, in the extension direction of the rotation axis O1, the second mounting seat 21 and the second cutter head 22 are disposed on both sides of the connecting seat 25.

[0074] The second cutter head 22 is mounted on the connecting seat 25. The connection between the second cutter head 22 and the connecting seat 25 includes, but is not limited to, screw connection, snap-fit, adhesive bonding, or welding.

[0075] The adjusting member 23 is movably disposed on the inner circumference of the second mounting base 21 along the extension direction of the rotation axis O1. The adjusting member 23 is connected to the second cutter head 22 via the connecting base 25.

[0076] Based on the above description, by using the second mounting base 21 to support the adjusting member 23 and the connecting base 25, and setting the connecting base 25 to be floatingly connected to the second mounting base 21, and simultaneously mounting the second cutter head 22 on the connecting base 25, the second cutter head 22 can be connected to the second mounting base 21 via the connecting base 25. Compared with not setting the connecting base 25 and using the second cutter head 22 to be floatingly connected to the second mounting base 21, the structure of the second cutter head 22 can be simplified, the structural strength of the second cutter head 22 can be optimized, and the grinding life of the second cutter head 22 can be improved.

[0077] It is understood that this embodiment is described using the example of the second cutter head 22 being movable relative to the first cutter head 12 in the extension direction of the rotation axis O1. In other embodiments, the first cutter head 12 may move relative to the second cutter head 22 in the extension direction of the rotation axis, or both the first cutter head 12 and the second cutter head 22 may be movable relative to each other in the extension direction of the rotation axis O1, so as to achieve the purpose of adjusting the gap between the first cutter head 12 and the second cutter head 22.

[0078] Furthermore, it is also understood that in other embodiments, the second cutter head assembly 20 may not have a connecting seat 25, but instead utilizes the floating connection between the second cutter head 22 and the second mounting seat 21 to achieve the movement of the second cutter head 22 on the rotation axis O1.

[0079] For example, the adjusting member 23 is threadedly connected to the second mounting base 21. In this way, the adjusting member 23 can move in the extension direction of the rotation axis O1 by the relative rotation between the adjusting member 23 and the second mounting base 21. The structure is simple, with few parts and low cost.

[0080] Based on this, exemplarily, the second cutter head assembly 20 also includes a wear-reducing plate 26. The wear-reducing plate 26 is supported on the connecting seat 25, and the surface of the wear-reducing plate 26 away from the connecting seat 25 is the wear-reducing surface. The adjusting member 23 abuts against the wear-reducing surface along the extension direction of the rotation axis O1. Specifically, since the adjustment member 23 moves in the extension direction of the rotation axis O1 by relative rotation between the adjusting member 23 and the second mounting seat 21, if the wear-reducing plate 26 is not provided, the frictional force generated between the adjusting member 23 and the connecting seat 25 when rotating will lead to severe wear between the adjusting member 23 and the connecting seat 25. In contrast, in this embodiment, by providing the wear-reducing plate 26 on the connecting seat 25 and having the adjusting member 23 abut against the wear-reducing surface along the extension direction of the rotation axis O1, the frictional force between the adjusting member 23 and the wear-reducing surface when rotating relative to the connecting seat 25 is reduced, avoiding wear of the connecting seat 25, and at least to a certain extent reducing the wear of the adjusting member 23.

[0081] For example, the wear-reducing pad 26 is made of metal, thus exhibiting good wear resistance. For instance, the wear-reducing pad 26 is made of stainless steel. Therefore, stainless steel is low-cost, highly wear-resistant, and easily machined into a smooth surface, reducing the roughness of the wear-reducing surface.

[0082] For example, the roughness of the friction-reducing surface is less than or equal to Ra2. For instance, the roughness of the friction-reducing surface can be Ra0.9, Ra1, Ra1.1, Ra1.2, Ra1.3, Ra1.4, Ra1.5, Ra1.6, Ra1.7, Ra1.8, or Ra1.9. Thus, the friction-reducing surface is a smooth surface, which helps reduce the frictional force when the adjusting member 23 rotates.

[0083] In some examples, to achieve a floating connection between connector 25 and second mounting base 21, please refer to 5, and in conjunction with it. Figure 6 The second mounting base 21 has a first mounting hole 211 extending through the second mounting base 21 along the extension direction of the rotation axis O1. The second cutter head assembly 20 also includes a first pin 292 and a first elastic member 291. The first pin 292 is movably disposed in the first mounting hole 211 along the extension direction of the rotation axis O1 and is connected to the connecting seat 25. The first elastic member 291 is compressed between the second mounting base 21 and the connecting seat 25.

[0084] As a result, the structure is simple and the processing cost is low. Furthermore, the first elastic element 291 allows the connecting seat 25 to always tend to move away from the second mounting seat 21, which facilitates the second cutter disc 22 to float to a certain extent during the grinding process of the grinding mechanism 100, depending on the size of the grinding material, and can also exert a certain effect on the grinding material, so as to improve the grinding effect of the grinding mechanism 100.

[0085] For example, the first elastic element 291 may include, but is not limited to, a spring. The material of the first elastic element 291 may include, but is not limited to, metal.

[0086] For example, the first elastic element 291 and the first pin 292 may be arranged at intervals along the circumference of the second mounting base 21. For instance, there may be multiple first elastic elements 291 and multiple first pins 292, which are arranged at intervals and alternately along the circumference of the second mounting base 21. As another example, the first elastic element 291 may also be sleeved on the first pin 292.

[0087] For example, please continue reading Figure 6 The connecting seat 25 has a first threaded hole 253 recessed in the connecting seat 25 along the extension direction of the rotation axis O1, and the first pin 292 is threadedly connected to the first threaded hole 253. In this way, the connection method between the connecting seat 25 and the first pin 292 is relatively simple and the assembly efficiency is high.

[0088] Please refer to some embodiments of this application. Figure 4 and Figure 6 The grinding mechanism 100 also includes a funnel component 27.

[0089] The funnel component 27 may be made of, but is not limited to, metal, plastic, and both. The funnel component 27 may be funnel-shaped or substantially funnel-shaped.

[0090] Please continue reading. Figure 4 The funnel component 27 forms a third channel 274.

[0091] The third channel 274 of the funnel component 27 can be located directly below the discharge port of the raw material box 200, or the discharge port can be located inside the third channel 274.

[0092] Please continue reading. Figure 4 The second cutter head 22 has a first channel 221, and the connecting seat 25 has a second channel 251.

[0093] The third channel 274, the second channel 251 and the first channel 221 are connected in sequence to form the feed channel of the second cutter head assembly 20.

[0094] It is understood that the funnel component 27 has a structure with a large opening at one end and a small opening at the other end. By setting the funnel component 27, the larger opening end of the funnel component 27 faces the raw material box 200, and the smaller opening end faces the second channel 251. This facilitates the grinding material discharged from the outlet of the raw material box 200 to enter the space between the first cutter disc 12 and the second cutter disc 22 through the feed channel, avoiding the problem of leakage or poor discharge of the grinding material discharged from the outlet of the raw material box 200.

[0095] Based on this, exemplarily, the funnel member 27 is rotatable about the rotation axis O1 relative to the second mounting base 21. The adjusting member 23 is movable relative to the funnel member 27 along the extension direction of the rotation axis O1. The funnel member 27 rotates about the rotation axis O1 to drive the adjusting member 23 to move along the extension direction of the rotation axis O1. In this way, the funnel member 27 can serve as a driving member for moving the adjusting member 23, thereby facilitating the user's operation of the grinding mechanism 100. Moreover, the funnel member 27 achieves multiple functions, thus eliminating the need for additional components connected to the adjusting member 23 for driving its movement, thereby simplifying the structure of the second cutter head assembly 20 and reducing costs.

[0096] In some embodiments, please continue reading Figure 4 , Figure 5 and Figure 6A rib 252 is provided at the end of the connecting seat 25 facing the second mounting seat 21. The rib 252 extends in a ring shape along the circumference of the second channel 251. The end of the funnel member 27 near the first channel 221 is located on the inner circumference of the rib 252. The adjusting member 23 is located on the outer circumference of the rib 252. In this way, during the process of the grinding material passing through the feed channel, the rib 252 can guide the movement of the grinding material from the third channel 274 to the first channel 221. If the rib 252 is not provided, there will be a gap between the end of the funnel member 27 near the first channel 221 and the end of the connecting seat 25 near the third channel 274, which will cause the grinding material to leak from the gap. The rib 252 makes the entire structure more conducive to the grinding material entering between the first cutter head 12 and the second cutter head 22 through the feed channel, and also facilitates the cleaning of the second cutter head assembly 20.

[0097] For example, the rib 252 and the connecting seat 25 can be integrally molded. This simplifies the overall processing of the rib 252 and the connecting seat 25, reduces manufacturing costs, and improves the connection strength between the rib 252 and the connecting seat 25. Alternatively, the rib 252 and the connecting seat 25 can also be connected by adhesive bonding, welding, snap-fitting, or screws.

[0098] For example, please continue reading Figure 6 The grinding mechanism 100 also includes a fixing member 28. The material of the fixing member 28 includes, but is not limited to, metal, plastic, and a combination of both. The shape of the fixing member 28 includes, but is not limited to, a ring shape extending circumferentially along the second mounting base 21.

[0099] The fastener 28 is fixed to the side of the second mounting base 21 away from the connecting base 25. The connection between the fastener 28 and the second mounting base 21 includes, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection.

[0100] The fastener 28 and the second mounting base 21 cooperate to limit the funnel component 27 in the extension direction of the rotation axis O1.

[0101] In this embodiment, by using the fixing member 28 to cooperate with the second mounting base 21 to limit the funnel member 27 in the extension direction of the rotation axis O1, it is not only easy to assemble, but also to prevent the funnel member 27 from moving during rotation, thereby improving the guiding effect of the funnel member 27 on the grinding material.

[0102] For example, please continue reading Figure 6 and Figure 7An annular retaining plate 271 extending axially along the outer periphery of the funnel component 27 is provided. The free end of the retaining plate 271 has an annular flange 273 extending away from the central axis of the funnel component 27. An annular limiting step 281 extending circumferentially along the funnel component 27 is formed on the surface of the fixing member 28 facing the funnel component 27. The thickness of the flange 273 along the axial direction of the funnel component 27 is less than the distance between the step surface of the limiting step 281 and the second mounting base 21 in the axial direction of the funnel component 27. That is, when one end of the flange 273 along the axial direction of the funnel component 27 abuts against the second mounting base 21, there is a gap between the other end of the flange 273 along the axial direction of the funnel component 27 and the step surface of the limiting step 281 in the axial direction of the funnel component 27. Therefore, the structure is simple and does not restrict the rotation of the funnel component 27.

[0103] For example, please refer to Figure 7 The adjusting component 23 has a locking groove 231 on its outer circumferential surface. The locking groove 231 extends through the adjusting component 23 along the rotation axis O1. The locking plate 271 has a locking rib 272 on its inner circumferential surface. The locking groove 231 engages with the locking rib 272. In this way, through the engaging action of the locking rib 272 and the locking groove 231, the adjusting component 23 can be driven to rotate when the funnel component 27 rotates. Since the locking groove 231 extends through the adjusting component 23 along the rotation axis O1, the engagement between the locking groove 231 and the locking rib 272 does not restrict the movement of the adjusting component 23 along the rotation axis O1 during the rotation of the adjusting component 23. The entire structure is simple, easy to manufacture, and low in cost.

[0104] In other embodiments, a locking rib 272 may be provided on the adjusting member 23, and a locking groove 231 may be provided on the inner circumferential surface of the locking plate 271.

[0105] For example, there can be multiple locking ribs 272, and correspondingly, there can also be multiple locking slots 231. Specifically, there is a one-to-one correspondence between the locking ribs 272 and the locking slots 231, with each locking rib 272 configured with one locking slot 231.

[0106] For example, the locking rib 272, the snap-fit ​​plate 271, the flange 273, and the funnel component 27 can be integrally molded. This simplifies the overall processing of the locking rib 272, snap-fit ​​plate 271, flange 273, and funnel component 27, reduces manufacturing costs, and improves the connection strength between them. Furthermore, for example, the locking rib 272 and the snap-fit ​​plate 271, the snap-fit ​​plate 271 and the funnel component 27, and the snap-fit ​​plate 271 and the flange 273 can also be connected by adhesive, welding, snap-fit, or screw connections.

[0107] For example, to facilitate the rotation of the funnel 27, the beverage machine 1000 may also include at least partially exposed operating handles (not shown). The operating handles are connected to the funnel 27 so that the user can drive the funnel 27 to rotate by operating the operating handles.

[0108] Please return to the reference. Figure 4 The grinding mechanism 100 also includes a drive motor 30 and a transmission component 40.

[0109] The transmission component 40 includes a transmission shaft 43, a primary transmission assembly 42, and a planetary gear transmission assembly 41. The transmission shaft 43 is arranged parallel to the motor shaft of the drive motor 30. The transmission shaft 43 is rotatable relative to the first mounting base 11.

[0110] The primary transmission assembly 42 includes a first external gear 421 and a second external gear 422. The first external gear 421 is mounted on the motor shaft of the drive motor 30. The second external gear 422 is mounted on the transmission shaft 43 and meshes with the first external gear 421. The planetary gear transmission assembly 41 connects the transmission shaft 43 and the first cutter head 12.

[0111] In this way, at least two transmission components, namely the primary transmission component 42 and the planetary gear transmission component 41, are provided between the drive motor 30 and the first cutter disc 12. This allows the transmission ratio between the drive motor 30 and the first cutter disc 12 to be changed. By changing the transmission ratio between the drive motor 30 and the first cutter disc 12, the rotational speed of the first cutter disc 12 can be changed, thereby improving the grinding effect of the grinding mechanism 100.

[0112] For some embodiments of this application, please refer back to the previous section. Figure 3 A second pin 15 and a second elastic element (not shown in the figure) are provided between the second cutter head assembly 20 and the first cutter head assembly 10. Specifically, a second pin 15 and a second elastic element are provided between the connecting seat 25 and the first mounting seat 11.

[0113] The first mounting base 11 has a second mounting hole. A second pin 15 is movably disposed in the second mounting hole along the extension direction of the rotation axis O1. A second elastic member is installed in the second mounting hole, with its elastic force direction along the extension direction of the rotation axis O1. One end of the second elastic member along the extension direction of the rotation axis O1 abuts against the second pin 15, and the other end abuts against the bottom wall of the second mounting hole. The second elastic member is always in a compressed state so that when the second cutter head assembly 20 is installed on the first mounting base 11, the second pin 15 abuts against the connecting seat 25 of the second cutter head assembly 20, thereby ensuring the reliability of the second cutter head assembly 20 after assembly.

[0114] This results in a simple structure and low manufacturing cost. Furthermore, the second elastic element ensures that the connecting seat 25 always tends to move away from the first mounting seat 11, allowing the aforementioned boss to abut against one side wall of the first groove 11A1, thus ensuring reliable connection between the first cutter head assembly 10 and the second cutter head assembly 20. Moreover, the abutment relationship between the second pin 15 and the connecting seat 25 does not affect the detachable configuration of the first cutter head assembly 10 and the second cutter head assembly 20.

[0115] For example, the second elastic element may include, but is not limited to, a spring. The material of the second elastic element may include, but is not limited to, metal.

[0116] For example, there are multiple second elastic elements and second pins 15, and the second elastic elements and second pins 15 can be spaced apart in the circumferential direction of the second mounting base 21.

[0117] For example, please continue reading Figure 3 The second pin 15 is located on the groove wall surface of the second groove 11A2 opposite to the notch 1121. The connecting seat 25 includes an abutment block 254. The abutment block 254 is located in the second groove 11A2 and abuts against the second pin 15.

[0118] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples without contradicting each other.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
