An insertion port is provided on the leak-proof protective cover 4, and the powder inlet end 50 of the powder guiding chamber 40 is inserted into the insertion port. The leak-proof protective cover 4 surrounds and fits against the outer periphery of the powder inlet end 50 of the powder guiding chamber 40.

[0025] Furthermore, the powder guiding chamber 40 is provided with a receiving surface 51 and a gathering area 52. The powder enters the powder guiding chamber 40 through the powder inlet end 50 and is sprinkled into the gathering area 52 under the action of the receiving surface 51.

[0026] Furthermore, a guide plate 6 is provided on the powder inlet end 50 of the powder guiding chamber 40, and the guide plate 6 has a U-shaped guide hole.

[0027] Furthermore, it also includes an installation groove 7 disposed in the powder box 10, and positioning strips 71 are symmetrically arranged on the inner side wall of the installation groove 7. Limiting grooves 53 are respectively provided on both sides of the powder guiding chamber 40.

[0030] The working principle of this utility model is as follows:

[0031] When grinding coffee beans, one end of the guide container 40 on the powder container 10 is inserted into the slot of the leak-proof protective cover 4. After assembly, the leak-proof protective cover 4 surrounds and adheres to the outer periphery of the guide container 40. When the burr assembly inside the machine body 1 rotates, it rotates and conveys the coffee powder to the outlet 3. The coffee powder enters the guide container 40 through the outlet 3, and then passes through the inlet 5 into the powder container 10. Compared with the prior art where the inlet 5 of the powder container 10 is directly attached to the outlet 3 on the grinding chamber 2, since one end of the guide container 40 of this application is inserted into the slot of the leak-proof protective cover 4, and the leak-proof protective cover 4 adheres to the outer periphery of the guide container 40, coffee powder leakage can be effectively prevented.

[0032] Based on the above technical solution, this application provides a connecting plate 41 inside the socket. One end of the connecting plate 41 is fixed to the powder outlet 3, and the other end is connected to the edge of the leak-proof protective cover 4. The connecting plate 41 and the leak-proof protective cover 4 together form a socket with a gradually increasing diameter. The shape of the socket is adapted to the powder inlet end 50 of the powder guiding chamber 40.

[0033] Based on the above technical solution, this application provides a receiving surface 51 and a gathering area 52 in the powder guiding chamber 40. The receiving surface 51 faces the direction of the rotating powder feeding of the burr assembly. When coffee powder is fed into the powder guiding chamber 40, the coffee powder is first sent to the receiving surface 51. Under the blocking effect of the receiving surface 51, the coffee powder will fall into the gathering area 52, and then move downward along the gathering area 52 and fall into the powder box 10. With this setting, more coffee powder can be sprinkled in the middle of the powder box 10, reducing the coffee powder adhering to the inner wall of the powder box 10.

[0034] Based on the above technical solution, this application provides a guide plate 6 at the powder inlet end 50 of the powder guide chamber 40. The guide plate 6 is provided with a U-shaped guide hole, which defines a vertical part 6-1 and a horizontal part 6-2. When the burr assembly rotates to feed the powder, the coffee powder first passes through the vertical part 6-1 and is conveyed to the receiving surface 51. As the burr assembly continues to rotate, the remaining coffee powder is conveyed to the receiving surface 51 through the horizontal part 6-2.

[0035] Based on the above technical solution, regarding the installation of the powder guiding chamber 40, this application provides an installation groove 7 on the powder box 10, a positioning strip 71 in the installation groove 7, and limit grooves 53 on both sides of the powder guiding chamber 40. When the powder guiding chamber 40 is installed in the installation groove 7, the positioning strip 71 is inserted into the limit groove 53.

[0036] Based on the above technical solution, this application provides a positioning frame 8 on the edge of the leak-proof protective cover 4 and an installation port 81 on the periphery of the powder inlet 5 of the powder box 10. When the powder guide chamber 40 is inserted into the insertion port of the leak-proof protective cover 4, the positioning frame 8 is limited within the installation port 81.

[0037] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
