Technical field

The invention relates to the field of opening mechanisms, and in particular to a linkage switch cover mechanism.

Background technique

Conventional rice cookers often install the bubble breaker on the cover body, and the bubble breaker is required to be removed for cleaning. However, the current cover body does not have a structure for preventing the bubble breaker from being leaked, so that the bubble breaker may be leaked. When the bubble breaker is leaking, the rice cooker may not be used or the cleaning may be difficult after use, which may affect subsequent use.

The utility model patent of the application No. 201420034456.5 discloses a rice cooker upper cover, an upper cover body; a handle, the handle is disposed on the upper cover body; a cover buckle plate, the open cover buckle plate is disposed on the upper cover body a cover body or the handle, and can be engaged or opened with a buckle on the body of the rice cooker; and a limit switch, the limit switch is movably disposed on the handle and can be in the working position And moving between the non-working position, and when the limit switch is moved to the working position, the opening and closing plate is prevented from opening with the buckle. At present, conventional rice cookers are opened and closed by means of interlocking and gusseting, and the use manner is simple, but on the new type of rice cooker, it is often necessary to add a bubble breaker for breaking bubbles, and such a bubble breaker is replaced. It is difficult to judge whether it is installed or not, and the existing rice cooker top cover is difficult to control.
