Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, specifically relating to a disassembly and assembly structure for a grinding machine bean box. Background Technology

[0002] With the global spread of coffee culture, home and commercial grinders, as core equipment for coffee preparation, have seen user concerns regarding ease of use, structural stability, and cleaning and maintenance efficiency. The bean hopper, a crucial component for coffee bean storage and supply, requires frequent disassembly and assembly for tasks such as replenishing beans and cleaning residual grounds to prevent cross-contamination of flavors or bacterial growth. Therefore, the design of the bean hopper's disassembly and assembly structure directly impacts the overall user experience and lifespan of the equipment.

[0003] In the current technology of grinders, the connection between the bean hopper and the main body is mainly divided into two categories: one is a threaded connection structure, which is fixed by rotating the bean hopper to make the threads mesh. Although this type of structure can provide high connection stability, during frequent disassembly and assembly, the threads are prone to jamming and stripping due to the accumulation of coffee bean powder, making disassembly and assembly difficult later, especially for users with weak hand strength, and the operation is not convenient; the other type is a snap-fit ​​connection structure, which fixes the bean hopper by the cooperation of plastic snaps and slots. Although it solves the jamming problem of threaded connections, the plastic snaps are prone to breakage due to fatigue deformation or uneven stress after long-term use, causing the bean hopper to loosen and fall off, and even generate shaking noise during grinding, affecting grinding accuracy and equipment safety.

[0004] In summary, current grinder bean hopper assembly and disassembly structures generally suffer from poor ease of operation, insufficient structural stability, limited functionality, and difficulties in cleaning and maintenance, failing to meet users' demands for efficient use, long-term durability, and safety and hygiene in grinders. Therefore, developing a grinder bean hopper assembly and disassembly structure that is simple in structure, easy to assemble and disassemble, has stable connections, and is multifunctional has become a key issue that urgently needs to be addressed in the current grinder technology field. Utility Model Content

[0005] This addresses the technical problem of inconvenient disassembly and assembly between the main body of the existing grinder and the bean container.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disassembly and assembly structure for a grinding mill bean box, comprising a main body and a bean box assembly. The opening at the top of the main body is provided with a hollow upper blade support. The inner wall of the upper blade support is provided with a positioning groove. A retaining spring is provided in the positioning groove. The retaining spring has several arc-shaped portions and several straight edges. The straight edges are provided between the arc-shaped portions. The arc-shaped portions are located in the positioning groove on the inner wall, and the straight edges are located on the outside of the positioning groove. The bean box assembly includes a bean box with a connecting part at the bottom. The connecting part of the bean box is inserted into the opening of the upper blade holder. The straight edge of the retaining spring abuts against the surface of the connecting part, so that the upper blade holder and the bean box are engaged by the retaining spring.

[0007] Furthermore, the bean box assembly includes a bean box lid, which is disposed on the top of the bean box.

[0008] Furthermore, the bean box assembly includes a bean box baffle, and the bean box has a track at the bottom of the storage space, with the bean box baffle located in the track.

[0009] The present invention has the following advantages: the connecting part of the bean box is inserted into the opening of the upper blade support, and the straight edge of the snap ring abuts against the surface of the connecting part, so that the upper blade support and the bean box are connected by the snap ring, and the bean box assembly cannot be easily detached. The structure is simple and the operation is convenient. Attached Figure Description

[0012] like Figures 1 to 5 As shown, a bean hopper disassembly and assembly structure for a grinder includes a main body 20 and a bean hopper assembly 10. The upper blade support 21 with a hollow structure is provided in the opening at the top of the main body 20. The upper blade support 21 has a positioning groove 22 in its inner wall. A retaining spring 23 is provided in the positioning groove 22. The retaining spring 23 has several arc-shaped parts 24 and several straight edges 25. The straight edges 25 are provided between the arc-shaped parts 24. The arc-shaped parts 24 are located in the positioning groove 22 on the inner wall, and the straight edges 25 are located on the outside of the positioning groove 22.

[0013] The bean box assembly 10 includes a bean box 11, and the bottom of the bean box 11 is provided with a connecting part 12. The connecting part 12 of the bean box 11 is inserted into the opening of the upper blade support 21. The straight edge 25 of the retaining spring 23 abuts against the surface of the connecting part 12, so that the upper blade support 21 and the bean box 11 are locked together by the retaining spring 23. The bean box assembly 10 cannot be easily detached. It has a simple structure and is easy to operate.

[0014] The bean box assembly 10 also includes a bean box lid 13 and a bean box baffle 14. The bean box lid 13 is placed on the top of the bean box 11 and can prevent foreign objects from entering the bean box 11.
