Description

A sealing structure with a detachable cover

technical field

The utility model belongs to the field of small kitchen appliances, in particular to a sealing structure with a detachable cover.

Background technique

Most of the rice cookers currently on the market have detachable covers, which are convenient for users to disassemble and clean while realizing the anti-overflow function. For a rice cooker with a visible window structure on the surface cover, a hole needs to be opened at the position corresponding to the visible window on the removable cover. In order to ensure sufficient air pressure in the pot, the hole needs to be sealed. The pressed part of the existing sealing structure is a block Shaped design, the elastic deformation after pressing is small, and the detachable cover is thin and the material is soft, it is difficult to completely seal the edge and the sealing structure after pressing, which affects the airtightness of the pot, and the gap formed is easy to hide Dirty and difficult to clean.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a sealing structure with a detachable cover that is easy to clean and has good airtightness.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a sealing structure of a detachable cover, the detachable cover includes a detachable cover plate, a detachable cover pressure plate fixedly connected with the detachable cover plate and a The first seal ring between the detachable cover plate and the detachable cover plate, the part of the first seal ring located between the detachable cover plate and the detachable cover plate is a bifurcated structure, and the upper part of the bifurcated structure The lower part of the bifurcated structure is sealed and fitted with the detachable cover plate. The elastic deformation of the bifurcated structure is larger than that of the block structure after being pressed, so that the edge of the thinner and softer detachable cover plate can also be completely sealed with the first sealing ring, so that it is not easy to leak air. Moreover, complete sealing also prevents a large gap between the detachable cover plate and the first sealing ring from causing dirt to be stored and inconvenient to clean.

Further, the edge of the opening of the detachable cover is provided with an inner flange for cooperating with the detachable cover pressing plate and the first sealing ring, and the inner flange is in interference fit with the first sealing ring. The interference fit between the inner flanging and the first sealing ring enables the formation of multi-layer seals between the detachable cover plate and the first sealing ring, thereby increasing the sealing performance, improving the cooking effect and cooking food with better taste.

Further, the detachable cover has a cover base, and a second sealing ring is provided between the cover base and the detachable cover plate. The design of the second sealing ring makes the air tightness between the detachable cover and the pot body better, so that the cooking effect is better.

Further, the outer edge of the detachable cover is provided with a buckle structure, and the cover seat is connected with the detachable cover through the buckle structure. The setting of the buckle structure makes the detachable cover plate penetrate the detachable cover cover seat and then flatten the detachable cover plate and the detachable cover to be relatively fixedly connected, which is convenient for installation.

Further, the detachable cover plate and the detachable cover pressure plate are riveted or screwed.

In summary, the utility model has the following advantages: the utility model has a simple structure and a beautiful appearance, the upper part of the bifurcated structure is closely attached to the detachable cover plate, and the lower part of the bifurcated structure is closely attached to the detachable cover plate. In this way, good airtightness between the detachable cover plate and the detachable cover pressure plate is achieved, sufficient air pressure in the pot is ensured, and dirt generated during use is prevented from entering the detachable cover and causing inconvenient cleaning.
