[0026] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0027] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0028] Referring to Figures 1-7 The elastic powder receiving ring according to the embodiments of the present application can be used in all bean grinders, integrated coffee grinders and the like, and is suitable for use with funnels of different sizes.

[0029] In one embodiment, as Figures 1-7 shown, an elastic powder receiving ring includes a powder receiving ring body 1.

[0030] The side of the powder receiving ring body 1 assembled with the powder receiving funnel 2 is provided with a plurality of elastic buckles 11 in the circumferential direction, the inner side surface of the elastic buckle 11 is provided with a convex portion 110, the convex portion 110 is used for interference fit contact with the powder receiving funnel 2, so as to assemble the powder receiving ring body 1 to the powder receiving funnel 2.

[0031] The inner side surface of the powder receiving ring body 1 is provided with an upper limiting portion 12 and a lower limiting portion 13 above and below the elastic buckle 11 respectively, the upper limiting portion 12 and the lower limiting portion 13 are used for limiting the powder receiving funnel 2 in the up and down directions.

[0032] Wherein, when the powder receiving funnel 2 is not connected, the outer side surface of the plurality of elastic buckles 11 and the outer side surface of the powder receiving ring body 1 are located on the same circumferential surface, and the inner side surface of the plurality of elastic buckles 11 and the inner side surface of the powder receiving ring body 1 are also located on the same circumferential surface, that is, each elastic buckle 11 itself is a part of the circular ring body of the powder receiving ring body 1, and the inner side surface is provided with the convex portion 110 used for interference fit contact with the powder receiving funnel 2.

[0033] In specific implementation, the elastic buckle 11 can play a good fitting role. When the powder receiving funnel 2 has a size deviation or the powder receiving ring body 1 has a size deviation, the elastic buckle 11 can still compensate for the deviation through elastic deformation to achieve a good tight fitting state. When the powder receiving funnel 2 is unscrewed from the powder receiving ring body 1, the elastic buckle 11 of the powder receiving ring body 1 can also be easily unscrewed, which is convenient to operate.

[0034] The above embodiment provides a deformable elastic powder receiving ring with a buckle structure. Due to the elastic deformation characteristics of the elastic buckle 11, the elastic assembly with the powder receiving funnel 2 can be realized, and the fitting performance is improved. The elastic operation during assembly is smooth, the wear is reduced, the service life is longer, and the consumer experience is improved. The size precision requirement is low, the part production control precision can be reduced, the yield is high, and the production cost is reduced.

[0035] In the embodiment, a plurality of mounting ears 21 are arranged on the powder receiving funnel 2 in the circumferential direction, and the number and position of the elastic buckles 11 correspond to the number and position of the mounting ears 21 one by one. The convex part 110 is used to be in interference fit with the outer diameter part 210 of the mounting ear 21 to assemble the powder receiving ring body 1 to the powder receiving funnel 2. The upper limiting part 12 and the lower limiting part 13 are used to limit the upper and lower surfaces of the mounting ear 21.

[0036] The number of elastic buckles 11 can be multiple. In order to ensure firm assembly, 2-5 elastic buckles 11 can be provided, preferably 3. The plurality of elastic buckles 11 are uniformly distributed on the circular ring body of the powder receiving ring body 1 in the circumferential direction. The upper limiting part 12 and the lower limiting part 13 are used to limit the upper and lower directions of the mounting ear 21, and play a guiding and limiting role during screwing in and out.

[0037] In specific implementation, when the powder receiving ring body 1 is assembled to the powder receiving funnel 2, the upper limiting part 12 and the lower limiting part 13 of the powder receiving ring body 1 clamp the mounting ear 21 in the upper and lower directions for rotational positioning, and then continue to screw in. At this time, the convex part 110 of the elastic buckle 11 is in contact with the outer diameter part 210 of the mounting ear 21, the elastic buckle 11 is lifted by the outer diameter part 210 of the mounting ear 21, and the convex part 110 is in a state of clamping the mounting ear 21, thereby playing a tight fitting role.

[0038] In the embodiment, the elastic buckle 11 is a cantilever structure connected to the powder receiving ring body 1 at one end and having gaps 111 between the other three surfaces and the powder receiving ring body 1.

[0039] The cantilever structure of the elastic buckle 11 has elastic function and can adapt to powder receiving funnels 2 of different sizes. Moreover, the structure is simple, can be directly machined on the powder receiving ring body 1, the process is simple, and the manufacturing cost is low.

[0040] In the embodiment, the upper limiting part 12 is a ring-shaped plane in contact with the upper surfaces of the plurality of mounting lugs 21. The ring-shaped plane can be a transition plane of the connecting portion to the powder blocking portion of the powder receiving ring body 1, or a plane formed by a convex ring separately provided on the inner side of the powder receiving ring body 1, which can be in contact with the upper surfaces of the mounting lugs 21 to serve as an upper limiting part to prevent the powder receiving funnel 2 from moving upward.

[0041] In the embodiment, the lower limiting part 13 is an L-shaped limiting plate, one end of which is parallelly arranged below the elastic buckle 11 with the bottom surface in the same plane as the lower end surface of the powder receiving ring body 1, and the other end of which is upwardly bent and vertically arranged in front of the elastic buckle 11.

[0042] The number of the lower limiting parts 13 is the same as that of the elastic buckles 11, and each lower limiting part 13 is arranged in one-to-one correspondence with each elastic buckle 11. In specific implementation, the L-shaped structure of the lower limiting part 13 can serve as a lower limiting part to prevent the powder receiving funnel 2 from moving downward, and can also abut against the front end of the mounting lug 21 to prevent the powder receiving funnel 2 from rotating and sliding, so that the powder receiving ring body 1 can be more firmly assembled on the powder receiving funnel 2.

[0043] In the above embodiment, the entire powder receiving ring body 1 is integrally formed, that is, the elastic buckle 11, the upper limiting part 12 and the lower limiting part 13 are integrated.

[0044] In a preferred technical solution, the powder receiving ring body 1 is provided with a ring-shaped powder blocking wall 14 on the side away from the powder receiving funnel 2, and a plurality of mounting lugs 15 are arranged on the outer side surface of the powder blocking wall 14 in the circumferential direction.

[0045] The mounting lugs can have the same or similar shape as the mounting lugs 21 of the powder receiving funnel 2, for example, a strip-shaped lug with a circular arc top edge. Since the powder receiving funnel 2 is sleeved in the inner hole of the powder receiving ring body 1 and assembled with the mounting lugs 21 and the elastic buckle 11, the mounting lugs 21 of the powder receiving funnel 2 cannot be placed on the funnel support of the coffee machine or the bean grinder, so the mounting lugs 15 are arranged on the outer side surface of the powder blocking wall 14 to facilitate placing the powder receiving funnel 2 assembled with the above-mentioned elastic powder receiving ring under the powder outlet of the coffee machine or the bean grinder.

[0046] In specific implementation, by arranging the mounting lugs 15 on the powder blocking wall 14, the powder receiving funnel 2 assembled with the above-mentioned elastic powder receiving ring can be placed under the powder outlet of the coffee machine or the bean grinder, so as to prevent shaking or movement during powder receiving.

[0047] In the embodiment, the material of the powder receiving ring body 1 is metal or plastic, which is convenient for manufacturing and production.

[0048] Other configurations and operations of the elastic powder connecting ring according to the embodiments of the present application are known to those skilled in the art, and will not be described in detail herein.
