[0002] In the field of abrasive equipment, grinders are widely used in scenarios such as grinding kitchen seasonings. In the prior art, to achieve the function of grinding multiple materials, dual-head grinders have emerged. For example, utility model patent CN222840891U discloses a dual-head grinder, which sets grinding mechanisms on both sides of one end of the machine body, connects the two grinding mechanisms using a drive source and transmission components, and achieves one grinding mechanism working while the other does not work during tilted grinding through the engagement and disengagement of a clutch gear set. This solves the problem of idle mechanisms doing useless work due to simultaneous grinding in traditional dual-head grinders, effectively improving service life.

[0003] However, existing dual-head grinding equipment still has certain drawbacks. On the one hand, the dual-head components have complex structures and a large number of parts, resulting in high production costs. On the other hand, the complex component composition makes the assembly process cumbersome, requiring a lot of time and manpower, resulting in low assembly efficiency and hindering large-scale production and widespread application. Therefore, there is an urgent need to develop a multi-purpose grinding equipment with a simpler structure, lower cost, and easier assembly. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described in detail with reference to the embodiments. Example 1

[0026] A single-head multi-purpose grinder includes a storage cup 1, a main unit 2, and a grinding head 3. The storage cup 1 and the grinding head 3 are respectively installed on both sides of the main unit 2. The storage cup 1 is screwed onto the main unit 2. A cup lid is installed at the end of the storage cup 1 and the cup lid is engaged with the cup body of the storage cup 1. The storage cup 1 is provided with a first raw material bin 11 and a second raw material bin 12. The first raw material bin 11 and the second raw material bin 12 can respectively store materials such as pepper and sea salt. The main unit 2 is equipped with a first raw material channel 21 and a second raw material channel 22. When the storage cup 1 is installed on the main unit 2, the first raw material bin 11 is connected to the first raw material channel 21, and the second raw material bin 12 is connected to the second raw material channel 22. The mill head 3 is equipped with a transfer chamber 31. A rotatable rotary switch 4 is installed between the main unit 2 and the mill head 3. When the rotary switch 4 is rotated, the transfer chamber 31 is connected to one of the raw material channels, the first raw material channel 21 and the second raw material channel 22. The transfer chamber 31 can accept not only one material from the first raw material bin 11 or the second raw material bin 12, but also materials from the first raw material bin 11 and the second raw material bin 12 can be accepted sequentially. The two materials are mixed in the transfer chamber 31 before grinding. This grinder, by setting a rotatable rotary switch 4 between the main unit 2 and the mill head 3 to control the connection status between the first raw material channel 21, the second raw material channel 22 and the transfer chamber 31 of the mill head 3, can realize that the two materials in the first raw material bin 11 and the second raw material bin 12 in the storage cup 1 can be ground together using a single mill head 3. Compared to traditional dual-head grinders that require two grinding mechanisms symmetrically set on both sides of the machine body 1, its advantages are: it eliminates the need for dual grinding mechanisms 2, and achieves multi-material grinding function through a combination of a single grinding head 3 and a rotary switch 4, reducing a set of core components such as grinding components 21, clutch gear set 22, and driven gear 23, thereby reducing material costs and processing complexity; at the same time, the single-head structure eliminates the symmetrical assembly process and debugging steps of dual grinding mechanisms 2, reducing the number of parts and assembly process, improving production efficiency, and better meeting the needs of low-cost, high-efficiency large-scale production.

[0027] An end cover 32 is installed on the machine head 3. In this embodiment, the end cover 32 is snapped into the machine head 3 and covers the transfer chamber 31. A rotary switch 4 is located between the end cover 32 and the main machine 2. The rotary switch 4 can rotate between the two. The end cover 32 has a cover window that communicates with the transfer chamber 31. The rotary switch 4 has a rotating window for adapting to the cover window. When the rotating window communicates with the cover window, the storage cup 1 will communicate with the transfer chamber 31. Integrating the rotary switch 4 between the end cover 32 and the main machine 2 results in a compact structure and reasonable layout. The channel switching function is realized through a standardized window adaptation method, avoiding the use of complex transmission components, simplifying the internal structure of the machine head 3, reducing the number of parts, reducing assembly difficulty and production costs, and enabling rapid switching of material channels through rotation operation, thereby improving ease of use and production efficiency.

[0028] The rotating window includes a first rotating window 42 and a second rotating window 43, both of which are square in shape. The cover window includes a first cover window 323 and a second cover window 324. The first raw material warehouse 11 is connected to the transfer warehouse 31 through the first rotating window 42 and the first cover window 323. The second raw material warehouse 12 is connected to the transfer warehouse 31 through the second rotating window 43 and the second cover window 324.

[0029] The upper end face of the end cap 32 has an upwardly protruding inner ring 321, and the inner side of the inner ring 321 has a protruding post 326 for installing screws. The lower end face of the main unit 2 has a downwardly protruding positioning block 23. The positioning block 23 is arc-shaped and wraps around the outside of the protruding post 326 for positioning. The positioning block 23 extends into the inner ring 321 and is adapted to the protruding post 326. The rotary switch 4 is fitted on the outside of the inner ring 321 and can rotate around the inner ring 321. Through the cooperation of the positioning block 23 and the inner ring 321, the relative position of the main unit 2 and the end cap 32 can be precisely defined, simplifying the alignment process during assembly and improving installation efficiency.

[0030] The rotary switch 4 has a guide block 41 on its lower end face and an arc-shaped guide groove 322 on its upper end face. The guide block 41 slides along the guide groove 322. The arc-shaped guide groove 322 provides a clear rotation trajectory for the guide block 41, ensuring the stability and accuracy of the rotary switch 4 during rotation and avoiding channel switching misalignment caused by shaking. The cooperation between the guide block 41 and the guide groove 322 forms a mechanical limiting structure, which can precisely control the rotation angle of the rotary switch 4 and ensure accurate switching of the connection state between the transfer chamber 31 and the first raw material channel 21 or the second raw material channel 22. This design achieves the guiding function through simple groove block cooperation, without the need for complex transmission components or positioning devices, simplifying the connection structure between the rotary switch 4 and the end cover 32, reducing processing difficulty and assembly costs, and improving the smoothness and reliability of operation.

[0031] The rotary switch 4 is equipped with an annular sleeve 44. Part of the annular sleeve 44 is fitted onto the outside of the main unit 2, and the other part of the annular sleeve 44 is fitted onto the outside of the end cover 32. The annular sleeve 44 increases the contact area with the operator's hand, making the rotation operation more effortless and convenient, and facilitating precise control of the rotation angle to switch the raw material channel. At the same time, the annular sleeve 44 completely covers the mechanical connection between the rotary switch 4 and the main unit 2 and the machine head 3, hiding the seam structure, preventing external impurities from entering or material leakage, improving product sealing and cleanliness, and enhancing the stability of the connection between the main unit 2 and the machine head 3 through the integrated sleeve connection.

[0032] A first gap 100 is provided between the inner wall of the annular sleeve 44 and the outer wall of the main unit 2, and a second gap 200 is provided between the inner wall of the annular sleeve 44 and the outer wall of the machine head 3. This provides room for the rotation of the rotary switch 4, avoids the annular sleeve 44 from being hindered by direct contact friction with the outer walls of the main unit 2 and the machine head 3, and ensures the smoothness of the rotary switch 4 when switching the raw material channel.

[0033] The main unit 2 includes a main unit housing 24. The first raw material channel 21 and the second raw material channel 22 are both located on the main unit housing 24. The lower end face of the main unit housing 24 has a curved groove 241, and the upper end face of the rotary switch 4 has a curved protrusion 45. Both the groove 241 and the protrusion 45 are annular in shape. The rotary switch 4 rotates and slides on the groove 241 via the protrusion 45. The groove 241 on the lower end face of the main unit housing 24 and the protrusion 45 on the upper end face of the rotary switch 4 are designed to cooperate, allowing the protrusion 45 to rotate and slide freely within the groove 241. The small contact area between the protrusion 45 and the groove 241 reduces the rotational resistance of the rotary switch 4, resulting in smoother rotation. This design also provides a stable rotational guide structure for the rotary switch 4, ensuring the positional accuracy of the rotary switch 4 when switching raw material channels.

[0034] The rotary switch 4 is provided with a first positioning groove 47, a second positioning groove 48 and a third positioning groove 49. The main unit 2 is equipped with an elastic element 25 and a positioning rod 26. One end of the positioning rod 26 presses on the elastic element 25 and the other end rests on the rotary switch 4. When the positioning rod 26 is positioned in the first positioning groove 47, the first raw material bin 11 is connected to the transfer bin 31. When the positioning rod 26 is positioned in the second positioning groove 48, the second raw material bin 12 is connected to the transfer bin 31. When the positioning rod 26 is positioned in the third positioning groove 49, neither the first raw material bin 11 nor the second raw material bin 12 is connected to the transfer bin 31.

[0035] The upper surface of the rotary switch 4 is provided with a first positioning groove 47, a second positioning groove 48, and a third positioning groove 49. The main unit 2 is equipped with an elastic element 25 and a positioning rod 26. The elastic element 25 is a spring. The main unit 2 has an installation groove, in which both the elastic element 25 and the positioning rod 26 are installed. One end of the positioning rod 26 presses against the elastic element 25, and the other end rests against the rotary switch 4. The left and right sides of the first positioning groove 47, the second positioning groove 48, and the third positioning groove 49 are all designed with ramps to facilitate the entry and exit of the positioning rod 26. When the positioning rod 26 is positioned in the first positioning groove 47, the first raw material bin 11 is connected to the transfer bin 31; when the positioning rod 26 is positioned in the second positioning groove 48, the second raw material bin 12 is connected to the transfer bin 31; when the positioning rod 26 is positioned in the third positioning groove 49, neither the first raw material bin 11 nor the second raw material bin 12 is connected to the transfer bin 31. The positioning rod 26 is matched with the first positioning groove 47, the second positioning groove 48 and the third positioning groove 49, so that the operator can quickly know that the rotary switch 4 has been rotated into place and determine whether the first rotary window 42 or the second rotary window 43 on the rotary switch 4 is fully open.

[0036] The main unit 2 is equipped with a battery 5, a motor 6, and a reducer 7. The battery 5 provides power to the motor 6. The output end of the motor 6 is connected to the reducer 7. The output end of the reducer 7 is equipped with a rotating shaft sleeve 8. A rotating shaft 9 is clamped on the rotating shaft sleeve 8. An inner grinding core 300 that can be raised and lowered is installed on the other end of the rotating shaft 9. The outlet end of the transfer chamber 31 is fixed with the inner grinding core 300. A grinding channel 700 is formed between the inner grinding core 300 and the outer grinding core 400. A spring 500 is fitted on the rotating shaft 9. One end of the spring 500 presses on the inner grinding core 300, and the other end of the spring 500 is supported on the bracket 311 in the transfer chamber 31.

[0037] An adjustment assembly 600 is installed at the lower end of the machine head 3. The adjustment assembly 600 includes a mounting platform 6001 and a cover plate 6002. The mounting platform 6001 is fastened to the body of the transfer chamber 31 by screws. A coarse and fine adjustment component 6003 is installed on the inner side of the mounting platform 6001. The cover plate 6002 covers the outlet end of the coarse and fine adjustment component 6003. An adjustment ring 6004 that can rotate on the outer side of the mounting platform 6001 is installed. The adjustment ring 6004 wraps around the mounting platform 6001. One end of the coarseness adjusting component 6003 is fitted onto the rotating shaft 9 and contacts the inner grinding core 300, while the other end is adapted to the adjusting ring 6004. The coarseness adjusting component 6003 has multiple slots of varying heights. The bottom of the adjusting ring 6004 is fixed with a top block for lifting the coarseness adjusting component 6003. When the adjusting top block is in different slots, the width of the grinding channel 700 between the inner grinding core 300 and the outer grinding core 400 will change accordingly. Example 2

[0038] Example 2 is basically the same as Example 1, except that the lower end face of the rotary switch 4 is provided with an annular groove 46, and the upper edge of the end cover 32 is provided with an upwardly protruding outer ring 325. The outer ring 325 extends into the annular groove 46, and the inner sidewall of the outer ring 325 seals with the inner sidewall of the annular groove 46. This seal is to prevent the powder after grinding from leaking out of the equipment. The cooperation between the outer ring 325 and the annular groove 46 forms an axial limiting structure, which can accurately constrain the relative position of the rotary switch 4 and the end cover 32, preventing the rotary switch 4 from moving up and down or radially offset during rotation, and ensuring the accuracy of the connection and switching between the transfer chamber 31 and the first raw material channel 21 and the second raw material channel 22.
