Description

TECHNICAL FIELD

[0001] The utility model relates to the field technology of chef machine, especially a chef machine capable of preventing food container from loosening. BACKGROUND

[0002] Chef machine, i.e. food processor, such as blender, shredder or multifunction machine, etc. is commonly used in people's life and can be used for stirring and processing food such as vegetables, fruits, beans, flour, eggs and butter. Generally, when the chef machine is used, the food container is placed on the base, and then the stirring assembly is inserted into the food container from the upper opening of the food container to perform stirring action. Therefore, the food container is prone to loosening or even falling off from the base due to vibration or external force during stirring.

[0003] In view of the above problems, some people in the industry have studied a scheme, CN118716903A discloses an intelligent chef machine with self-protection function, which comprises a base and a material barrel. The material barrel has a base, and the base is provided with a mounting groove corresponding to the base. The side wall of the mounting groove is provided with an elastic protrusion, and the base is provided with a bayonet corresponding to the elastic protrusion. The base is detachably connected to the mounting groove. It also includes a locking mechanism, which includes a push rod inside the base. The base is also provided with a jack. When the elastic protrusion is separated from the bayonet, the push rod moves horizontally towards the jack to make the push rod extend into the jack. When the material barrel base is correctly placed in the mounting groove, the elastic protrusion cooperates with the bayonet to realize the stable fixation of the material barrel. When the elastic protrusion and the bayonet are accidentally separated, the push rod in the locking mechanism will move horizontally and extend into the jack on the material barrel base, thereby locking the material barrel and preventing it from falling off or moving.

[0004] However, the structure of the locking mechanism is complex, and the push rod needs to be driven by a driving device (including a micro motor, a first transmission and a second transmission) to move, which is high in cost.
