[0003] This utility model relates to the field of coffee grinder technology, and in particular to a grinding cup mounting structure. Background Technology

[0004] In coffee grinders, in order to increase the lifespan and quality of the grinding cup, the existing grinding cups are made of metal. However, since the grinding cup is to be installed on the base, it is difficult to make complex shapes with a metal cup. Therefore, a plastic cup holder is added to the bottom of the cup. The cup and the cup holder are connected to form the grinding cup, which is then installed on the base with the help of the cup holder.

[0005] Existing grinding cups often use screws to secure the cup body and base. However, tightening the screws requires manual operation to tighten each screw individually. This process is not only time-consuming and labor-intensive but also increases operational complexity, making it difficult to achieve fast and accurate assembly and limiting production efficiency. Secondly, this method requires welding or machining screw holes on the cup body for assembly, thus increasing material and labor costs. Therefore, it is necessary to improve the existing technology to solve these problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0038] Example 1:

[0039] This utility model provides a grinding cup mounting structure, such as Figures 1 to 7As shown, it includes a cup body 1 and a cup base 2; the outer circumferential surface of the bottom of the cup body 1 is provided with a recessed snap-fit ​​structure, the cup base 2 is provided with a downwardly recessed snap-fit ​​part 20, the inner circumferential surface of the snap-fit ​​part 20 is provided with a protruding snap-fit ​​structure, the bottom of the cup body 1 extends into the snap-fit ​​part 20, and the protruding snap-fit ​​structure can snap into the recessed snap-fit ​​structure to fix the cup body 1 to the cup base 2; the cup body 1 is made of metal, and the cup base 2 is made of plastic.

[0040] Based on the above structural design, the cup body 1 can be firmly assembled through the cooperation of the protruding snap-fit ​​structure and the recessed snap-fit ​​structure, realizing the rapid assembly of the cup body 1 and the cup holder 2 without additional processing, thus reducing material and labor costs. The deformation of the plastic cup holder 2 is elastic deformation, that is, it can rebound to return to its original state after deformation, ensuring that the cup body 1 can be easily assembled into the cup holder 2, and it is not easy to fall off the cup holder 2 during use, avoiding accidents. The stainless steel cup body 1 can withstand the pressure and wear during the grinding process, extending the service life of the grinding cup.

[0041] In this embodiment, the outer circumferential surface of the bottom of the cup body 1 is provided with multiple grooves 11, which are recessed snap-fit ​​structures as described above. The inner circumferential surface of the snap-fit ​​part 20 is provided with multiple protrusions 21 that fit with the grooves 11. The protrusions 21 are protruding snap-fit ​​structures as described above. The protrusions 21 can snap into the grooves 11 to fix the cup body 1 to the cup base 2. The protrusions 21 are connected to the top of the cup base 2 by means of the first snap-fit ​​ring 22, and the grooves 11 are connected to the outer wall of the cup body 1 by means of the first mating ring 12. The first mating ring 12 fits against the first snap-fit ​​ring 22. When it is necessary to install the cup body 1, simply press the cup body 1 so that the bottom of the cup body 1 enters the snap-fit ​​part 20 of the cup base 2 along the first snap-fit ​​ring 22 until the protrusions 21 snap into the grooves 11, so that the cup body 1 is firmly assembled. The cooperation between the protrusions 21 and the grooves 11 can achieve a stable connection between the cup body 1 and the cup base 2, ensuring that the product will not loosen or fall off during use.

[0042] In this embodiment, three grooves 11 and three protrusions 21 are provided. The number of grooves 11 and protrusions 21 provides a more reliable connection, which is the best choice after balancing production costs and performance.

[0043] In this embodiment, the outer wall section of the cup body 1 where the groove 11 is provided includes a first outer vertical section 121, a first outer concave arc section 122, a first outer oblique section 123, a first outer convex arc section 124, a second outer concave arc section 125, a second outer vertical section 126, a second outer convex arc section 127, and a third outer vertical section 128 connected sequentially from top to bottom. The first outer oblique section 123 and the first outer convex arc section 124 are first mating rings 12. The inner wall section of the cup seat 2 where the protrusion 21 is provided includes a first inner oblique section 221, a first inner convex arc section 222, a first inner concave arc section 223, a first inner vertical section 224, a second inner convex arc section 225, and a second inner vertical section 226 connected sequentially from top to bottom. The first inner oblique section 221 and the first inner convex arc section 222 are first locking rings 22. The above structural design makes it easier for the cup body 1 to snap into the snap-fit ​​part 20 of the cup holder 2, making installation easier and more convenient, and the connection between the cup body 1 and the cup holder 2 is more secure after snapping in.

[0044] In this embodiment, the cup holder 2 is provided with multiple drainage and ventilation holes 27. The drainage and ventilation holes 27 can prevent the space between the cup body 1 and the cup holder 2 from being too sealed, and play a role in ventilation and expelling water vapor.

[0045] In this embodiment, the top of the cup body 1 is provided with an outwardly curved edge 17. The curved edge 17 makes the top of the cup body 1 more rounded and smooth, reducing friction and discomfort with the hand and improving the overall user experience.

[0046] In this embodiment, the mounting structure of the grinding cup further includes a grinding component 3 and a mounting component 4. The snap-fit ​​portion 20 of the cup seat 2 is provided with an upwardly protruding mounting base 28, and the bottom of the cup body 1 is provided with an upwardly recessed mounting groove 16. The mounting base 28 can enter the mounting groove 16. The mounting component 4 is mounted on the mounting base 28, and the grinding component 3 is mounted inside the cup body 1 through the mounting component 4. Specifically, the grinding component 3 and the mounting component 4 are prior art, and their structure and working principle will not be described in detail in this application.

[0047] Example 2:

[0048] The difference between Example 2 and Example 1 lies in the different structures of the recessed snap-fit ​​structure and the protruding snap-fit ​​structure; otherwise, they are the same as in Example 1.

[0049] In this embodiment, as Figures 8 to 13As shown, an annular groove 13 is provided on the outer circumferential surface of the bottom of the cup body 1. The annular groove 13 is a recessed snap-fit ​​structure as described above. A protruding ring 23 is provided on the inner circumferential surface of the snap-fit ​​part 20, which fits into the annular groove 13. The protruding ring 23 is a protruding snap-fit ​​structure as described above. The protruding ring 23 can snap into the annular groove 13 to fix the cup body 1 to the cup base 2. The protruding ring 23 is connected to the top of the cup base 2 by means of a second snap-fit ​​ring 24. The annular groove 13 is connected to the outer wall of the cup body 1 by means of a second mating ring 14. The second mating ring 14 fits snugly with the second snap-fit ​​ring 24. When it is necessary to install the cup body 1, simply press the cup body 1 so that the bottom of the cup body 1 enters the snap-fit ​​part 20 along the second snap-fit ​​ring 24 until the protruding ring 23 snaps into the annular groove 13, so that the cup body 1 is firmly assembled, realizing the rapid assembly of the cup body 1 and the cup base 2 and improving the assembly efficiency.

[0050] In this embodiment, the snap-fit ​​part 20 is provided with a positioning protrusion 25, and the bottom surface of the cup body 1 is provided with a positioning groove 15, so that the positioning protrusion 25 can enter the positioning groove 15. Through the cooperation of the positioning protrusion 25 and the positioning groove 15, the circumferential rotation of the cup body 1 is effectively restricted, thereby enhancing the stability of the cup body 1 during use.

[0051] In this embodiment, the inner circumferential surface of the snap-fit ​​portion 20 is provided with a plurality of deformation grooves 26, which are spaced apart around the convex ring 23 to divide the convex ring 23 into multiple segments. The deformation grooves 26 allow the convex ring 23 to undergo greater deformation when the cup body 1 is installed, thereby fitting more tightly to the annular groove 13 and ensuring that the cup body 1 is installed more securely.

[0052] In this embodiment, the cross-section of the outer peripheral surface of the cup body 1 includes, from top to bottom, a fourth outer vertical segment 141, a third outer concave arc segment 142, a second outer oblique segment 143, a third outer convex arc segment 144, a fourth outer concave arc segment 145, a fifth outer vertical segment 146, and a fifth outer concave arc segment 147; the second outer oblique segment 143 is a second mating ring 14; the cross-section of the inner peripheral surface of the cup seat 2 includes, from top to bottom, a second inner oblique segment 241, a third inner convex arc segment 242, a second inner concave arc segment 243, a third inner vertical segment 244, and a third inner concave arc segment 245; the second inner oblique segment 241 is a second locking ring 24. Through the above structural design, the cup body 1 can more easily be locked into the locking part 20 of the cup seat 2, making installation easier and more convenient, and the connection between the cup body 1 and the cup seat 2 is more secure after locking.

[0053] In summary, this grinding cup mounting structure can solve the problems of existing technologies where the grinding cup body and cup base are locked with screws, resulting in time-consuming and labor-intensive assembly, low assembly efficiency, and high material and labor costs.

[0054] Where there is no conflict, the above embodiments and features can be combined with each other.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
