Abstract
The utility model discloses an electric pressure cooker, which comprises a cooker cover, a cooker body, a liner, a heating plate and a control circuit. The cooker cover tightly locks the cooker body. Hermetic closure between the liner and the cooker cover is realized by a sealing ring, so that a pressure cavity is formed. The cooker cover is provided with a pressure valve, wherein, the cooker cover is provided with a trigger controlling the electric on-off of the heating plate and a cooker cover self-locking mechanism which ensures that the cooker cover under the upper-pressure state cannot be opened. The pressure valve drives the trigger and is locked with the cooker cover self-locking mechanism. A support seat is arranged on the cooker cover. The trigger, the self-locking mechanism and the pressure valve are all installed on the support seat and encapsulated in the cooker cover by a decorative cover. On the one hand, the utility model with a safe, precise structure can still directly utilize the pressure signal in the cooker to control the operation of the heating plate and sufficiently utilize the high-pressure theory and the advantage of limiting the overexpansion of cooker pressure, and on the other hand, because the pressure valve cooperates with the cooker cover self-locking mechanism to realize the self locking of the cooker cover, when high pressure exists in the cooker, a user cannot open the cooker cover, thus avoiding the occurrence of accidents.
