[0002] A milk frother is a device used to froth milk liquid into milk foam. It is mostly used in various beverage shops. The milk frother generally includes a stirring mechanism and a frothing mechanism. When frothing milk, the raw materials usually need to be put into the stirring mechanism. The stirring mechanism stirs and mixes the various raw materials through the stirring shaft, and then the mixed raw materials are input into the frothing mechanism for frothing to form milk foam. Since milk is a perishable food, some raw materials will generally remain on the stirring shaft, which is easy to stink and deteriorate, so it needs to be cleaned frequently. However, the frothing mechanism generally has a complex structure, and the various parts of the frothing mechanism need to be disassembled before it can be cleaned. Multiple cleanings require the frothing mechanism to be disassembled and assembled multiple times, which is time-consuming and labor-intensive, making the work of the beverage shop staff more cumbersome.
