Embodiment 1

[0035] Embodiment one: if figure 1 and figure 2, a pressure cut-off device for an electric pressure cooker, comprising a base 8, a base 1 and an upper cover 12, wherein the base 1 and the base 8 are fixed by rivets 27. Two sections of wires 33 are pierced on the upper cover 12 . The two sections of wires 33 form a current loop with the circuit inside the pressure breaker device. The two sections of wires 33 are connected to the same connector 32 outside the base 1 .

[0036] refer to image 3 and Figure 4 , the base 8 is provided with an air inlet port 9 and a sealing ring 10 for sealing the air inlet port 9. The sealing ring 10 is made of plastic material, and the middle part of the sealing ring 10 is sunken downward. When the base 1 is matched with the base 8, the base 1 is stuck Tighten the outer edge of the sealing ring 10; the base 8 is provided with an air intake duct 11 communicated with the air intake port 9. The action process of the sealing ring 10 is as follow...

Abstract

The invention discloses an electric pressure cooker and a pressure power-off device thereof. The essential of the technical scheme is that the pressure power-off device of the electric pressure cooker comprises a base, wherein the base is provided with a movable contact piece and a static contact piece, which are in electric connection; the movable contact piece is provided with an elastic piece which elastically abuts against the static contact piece; the base is provided with a swinging part for rotating and linking the elastic piece to be separated from the static contact piece and a reed which is in clamping joint with the swinging part; the base is provided with a movable shaft for pushing the swinging part and enabling the reed to span across a compression critical point; a linear movement process of the movable shaft is converted into an elastic potential energy storage process of the reed; when the reed spans across the compression critical point, the elastic potential energy of the reed is converted into kinetic energy, the swinging part is linked to rotate rapidly and then the electric connection is disconnected, so that rapid and accurate power-off aiming at electric appliances is realized and the safety is improved.

Description

technical field [0001] The invention relates to a pressure power-off structure, in particular to an electric pressure cooker and a pressure power-off device thereof. Background technique [0002] When the pressure cooker is in operation, it will cause abnormal internal pressure when its safety parts fail, in order to realize its safety, it is necessary to cut off the heating power supply in time. [0003] At present, the Chinese patent with the publication number CN203953296U on the market discloses a pressure switch, comprising: a switch base; It is a cantilever shape arranged on the switch base, and the pressure spring is provided with a movable contact; a static contact shrapnel, the static contact is a cantilever shape arranged on the switch base, and the static contact The shrapnel is located between the pressure shrapnel and the touch shrapnel, and the static contact shrapnel is provided with a static contact opposite to the moving contact, and the static contact is o...
