[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of a food processor may mainly include, but are not limited to, making soy milk, squeezing juice, making rice paste, mincing meat, shaved ice, making coffee and / or preparing facial masks. Food processors may include machines for crushing and mixing food, such as soy milk machines, blenders or wall-breaking food processors. In order to achieve different functions such as mincing meat, shredding and kneading noodles, the food processor needs to provide different speeds for the mixing blade assembly. However, existing food processors generally use the following two methods to achieve multi-functions: 1. The motor itself can achieve output at different speeds; 2. Different speed change devices are set in different mixing cups. However, both of the above methods have the problem of high cost. Utility Model Content
