Abstract

The invention discloses a pressure device comprising a device body and an over-pressure protection switch; the over-pressure protection switch comprises a switch body, a first switch terminal, a second switch terminal, a trigger retaining member, a touch device and a sealing device. the first switch terminal is provided with a first contact; the second switch terminal is provided with a second contact; the trigger retaining member comprises a trigger member and an elastic retaining member; the elastic retaining member is connected between a free end of the trigger member and a second end of the second switch terminal; when the pressure in the device body reaches a preset pressure, the pressure in the device body is applied to the sealing device through a connecting port; the sealing devicedrives the touch device to move horizontally to trigger the trigger member so that the elastic retaining member pulls the second end of the second switch terminal away from the second contact so thatthe second contact moves from a contacting position to a break off position and is kept at the break off position. According to the pressure device of the invention, the power off protection under abnormal over-pressure is achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a pressure appliance. Background technique [0002] In the related art, the normal pressure range of the electric pressure cooker is 70kPa (kiloPascal). During the normal use of the electric pressure cooker, a pressure relief valve or a leak between the pot body and the cover of the electric pressure cooker is usually used to realize normal pressure relief. However, when the pressure relief valve fails or there is no normal leakage between the pot body and the cover to discharge the gas in the electric pressure cooker, the electric pressure cooker is prone to burst open, thereby causing harm to users. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to propose a pressure appliance, which increases the safety of use of the pressure applian...
