The hard cleaning teeth can be made of high-strength stainless steel or plastic with a specific hardness.

[0021] The cleaning teeth are gradually inclined from top to bottom. Specifically, the gradually inclined cleaning teeth can more effectively adapt to the shape and size of the grinding assembly. The inclined cleaning teeth can help to better push and agitate the grinding material, making it easier to remove residual grinding material. At the same time, it also helps to evenly distribute the grinding material, thereby improving the balance and overall taste of extraction.

[0022] The cleaning teeth include a first guide slope and a second guide slope. Specifically, the design of the first guide slope enables the cleaning teeth not only to push and clean the coffee powder, but also to effectively guide the coffee powder to move to the outlet of the grinding assembly, which helps to reduce the accumulation and residue of coffee powder and improve the thoroughness of cleaning. The second guide slope helps to more effectively agitate and push the coffee powder during the grinding process, ensuring more uniform grinding.
