[0031] Such as Figures 1 to 6As shown in the figure, a grinding bin structure of a coffee machine includes a coffee machine main body 1, a grinding bin 2 is arranged on the coffee machine main body 1, a transmission member 3 is arranged above the grinding bin 2, the transmission member 3 is connected and driven by a driving device 4 arranged in the coffee machine main body 1, a stirring member 5 is assembled on the transmission member 3, a plurality of stirring bars 51 extending into the grinding bin 2 are arranged on the stirring member 5, and the outer surface of the stirring bar 51 is closely attached to the inner surface of the grinding bin 2.

[0032] The above driving device 4 is preferably a motor.

[0033] In this embodiment, a driving gear 41 is connected to the driving device 4, a transmission tooth 31 is arranged on the outer periphery of the transmission member 3, and the transmission tooth 31 meshes with the driving gear 41. The driving device 4 and the transmission member 3 are connected and driven by a gear transmission structure, which has a simple structure, reliable transmission and low running noise.

[0034] The transmission member 3 includes an outer ring 32 and an inner ring 33, a plurality of spokes 34 are arranged between the outer ring 32 and the inner ring 33, and a clamping groove 5a adapted to the spoke 34 is arranged on the stirring member 5.

[0035] The spoke 34 is inclined, and correspondingly, the clamping groove 5a is also inclined.

[0036] The transmission member 3 and the stirring member 5 are connected and driven through the cooperation of the spoke 34 and the clamping groove 5a. When the stirring member 5 is assembled with the transmission member 3, it automatically falls into place by the gravity of the stirring member 5. Here, the spoke 34 is inclined, which can improve the reliability of the connection.

[0037] The inner ring 33 of the transmission member 3 is assembled at the upper end of the transmission shaft 6, and the lower end of the transmission shaft 6 is assembled with the grinding cutter head 71 of the grinding assembly 7. Such a setting makes the grinding cutter head 71 coaxial with the transmission member 3. In this way, the driving device 4 drives the transmission member 3 to rotate, and then the transmission shaft 6 drives the grinding cutter head 71. That is to say, one driving device 4 can drive the rotation of both the stirring member 5 and the grinding cutter head 71 at the same time, and the structure is more compact.

[0038] The grinding assembly 7 includes a mutually adapted grinding cutter head 71 and a cutter head seat, and a tooth groove is arranged on the inner ring of the cutter head seat. The grinding assembly 7 is a prior art, and its structure will not be elaborated here.

[0041] The upper part of the stirring bar 51 is thick and the lower part is thin.

[0042] The stirring member 5 is an integrally formed integral structure.

[0043] The stirring member 5 is made of a flexible material. Flexible materials such as silica gel and rubber can be selected. To improve the reliability of the installation of the transmission shaft 6, a bracket 21 is provided in the grinding bin 2. Since the stirring bar 51 of the stirring member 5 is flexible and deformable, when the stirring bar 51 encounters the bracket 21, it deforms and avoids the bracket 21.

[0044] Working principle:

[0045] For the grinding bin structure of a coffee machine of the present utility model, a stirring member 5 driven to rotate by a driving device 4 is provided in the grinding bin 2, and the outer surface of the stirring bar 51 of the stirring member 5 is closely attached to the inner surface of the grinding bin. When the stirring member 5 rotates, it can stir the coffee beans in the grinding bin 2 and at the same time can scrape the residues adhering to the inner surface of the grinding bin 2.

[0046] Specifically, the driving device 4 drives the driving gear 41 to rotate. The driving gear 41 meshes with the transmission teeth 31 on the outer periphery of the transmission member 3, thereby driving the transmission member 3 to rotate. The stirring member 5 is engaged with the spoke 34 of the transmission member 3 through the card slot 5a. The rotation of the transmission member 3 drives the stirring member 5 to rotate in the grinding bin 2, completing the stirring of the coffee beans and the scraping of the residues on the inner wall of the grinding bin 2.

[0047] At the same time, the rotation of the transmission member 3 drives the transmission shaft 6 to rotate, and then the transmission shaft 6 drives the grinding cutter head 71 to rotate, so as to realize the simultaneous rotation of the driving device 4 driving the stirring member 5 and the grinding cutter head 71.

[0048] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and drawings of the present utility model should be included in the protection scope of the present utility model.
