Description

TECHNICAL FIELD The invention relates to a technical field of household appliance, and more particularly to a food preparation device. BACKGROUND A food preparation device is a household appliance that integrates functions of preparing soy milk, grinding dry powder, squeezing juice, mincing meat, shaving ice, and so on. Moreover, the food preparation device is the household appliance used to prepare various kinds of food such as juice, soy milk, jam, dry powder, shaved ice, minced meat and so on, and is a product that is multi-functionalized from a juicing machine. Safety performance is vital to the household appliances such as the food preparation device. At present, the food preparation device commercially available generally adopt a split structure, including a body and a detachable container. When the food preparation device is in operation, a motor in the body rotates at a high speed and drives a knife or a stirring member in the container to rotate so as to complete food preparation. At this time, the container needs to be locked on the body to avoid a safety accident caused by removal of the container during operation of the food preparation device. In the prior art, a locking member is provided in the body, and the locking member slides in a horizontal direction toward an inside of the body to cooperate with the container, so as to lock the container and the body together. Although this structure can improve the safety performance of the food preparation device, the locking member occupies a larger space, which makes a size of the body larger. Therefore, there is a need for a food preparation device that can lock the container and the body together and can reduce the size of the body. EP2371251A describes an electromotive operated food processor which comprising an agitator vessel which is sealed by a cover. A sealing is arranged between the cover and an opening edge of the agitator vessel, where the cover is locked by one or multiple moving bolt elements. The bolt elements are moved hydraulically or pneumatically or mechanically. EP2371251A is also related to a preparation container for boiling, cooking or steaming of food.
