Embodiment 1

[0037] Embodiment one: if figure 1 , a pressure cut-off device for an electric pressure cooker, comprising a base 1, an upper cover 13 cooperating with the base 1 through rivets 33, a connector 31 for electrical connection, the connector 31 includes two sections of wires 36 penetrating into the base 1. The upper cover 13 is provided with a glue injection hole 30 , and the glue injection hole 30 penetrates to the mating surface of the base 1 and the upper cover 13 .

[0038] combine figure 2 , the base 1 is provided with a first alignment body 28, and the positioning plate is provided with a second alignment body 35. After the base 1 and the upper cover 13 are matched, the first alignment body 28, the second alignment body 5 and the upper The cover 13 realizes plug-in fit, and forms a connection groove 29 through which two sections of wires 36 pass. When assembling the upper cover 13 and the base 1 , fix them with rivets 33 first, and then dispense glue through the glue inje...

Abstract

The invention discloses an electric pressure cooker and a pressure power-off device thereof. The pressure switch-off device is characterized in that a base is included, the base is provided with a movable contact and a static contact which are used for electrical connection, and the movable contact is provided with an elastic sheet elastically abutting against the static contact; the base is provided with a push key, a first elastic part which is linked to the push key to separate the elastic sheet from the static contact and a support part with a check block for limiting sliding of the push key. According to the pressure switch-off device, through critical value type limitation of the support part, a linkage relation is quickly triggered when the steam pressure reaches a critical value, so that electrical connection of the movable contact and the static contact is quickly disconnected; disconnecting critical value regulation and control are achieved through a regulating cover and a second elastic part, and a steam pressure value needed when electrical connection of the movable contact and the static contact is disconnected can be regulated and controlled according to the different using conditions.

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...
