The invention relates to a method for avoiding hard switch of beam pressure cooker. Wherein, it prepares the cover into cover top and cover bottom; two sides of cover bottom are mounted with cover ears; two ends of flexible beam are inserted into the cover ears; the cover top, the cover bottom and the inter O-shaped sealing ring are compressed; the lower open of cover bottom is mounted with Y-shaped sealing ring; since the flexible beam is compressed with cover top and cover bottom, without movable elements, the whole cover is integrated; and since it uses Y-shaped sealing ring, the cover can be closed by rotating cover to push the cover ear into cooker ear. |
