The invention provides a soybean milk machine with a split style cup body structure. The soybean milk machine comprises a cup body and a machine head buckled on the cup body, wherein the cup body comprises a body and a connecting ring arranged on the body; and the machine head is covered on the connecting ring and is electrically connected with the body. As the split style cup body is adopted, the soybean milk machine with the split style cup body structure of the invention not only can meet the requirement of the depth of the cup body for boiling soybean milk, but also can meet the requirement of depth of the cup body for cooking a soup and the like, improves the adaptability and practicality of the cup body, and is beneficial to the inter-class integration of functions of the soybean milk machine. Because a printed circuit board (PCB), a heating device and the like are arranged in the body of the cup body, the body can be independently used. For example, after a cover body is configured, the body can be assembled into an electric slow cooker, an electric chafing dish pot and the like, thereby realizing the diversification of functions of the soybean milk machine. Furthermore, the connecting ring of the cup body can be made from materials with a relatively low cost, so that the cost of the whole machine is reduced.
