Background technique

[2] With the development of society, the improvement of people's living standards and quality of life, coffee has become a popular drink, and is widely favored by consumers. The coffee processing process comprises the following three steps: Step one, grinding the coffee beans into coffee powder; Step two, loading the coffee powder into the coffee box; and, Step three, pressing the coffee powder in the coffee box. Under normal conditions, coffee powder is easily oxidized and loses its fragrance. Therefore, a grinder that can grind coffee beans into coffee powder by ordinary consumers has emerged. Since the grinders on the existing market only have the function of grinding, and do not have the functions of loading and pressing, there are the following disadvantages: First, consumers need to use coffee in addition to the existing grinders. The powder extrusion machine; Secondly, the consumer needs to implement three operation actions throughout the processing, the operation is complicated, troublesome, and cannot meet the needs of the consumer.

Summary of the invention

[3] The present invention provides a novel fully automatic grinder that overcomes the deficiencies of the prior art grinders that are complicated, cumbersome, and unable to meet the needs of consumers.

[4] The technical solution adopted by the present invention to solve its technical problems is:
