Safety electric pressure cooker

Abstract

The invention discloses a safe pressure cooker which is characterized in that a sealing plate (6) is arranged in the cooker; the edge of the sealing plate (6) is equipped with a sealing ring (7); the sealing plate (6) is sealed with an inner pot (3) through the sealing ring (7); an elastic element (2) is arranged among the inside of the cooker, a cooker cover (1) and the sealing plate (6); the upper part of the elastic element (2) is connected with the cooker cover (1); the sealing plate (6) is movably connected with the lower part of the elastic element (2) or the cooker cover (1); the pressure generating from the cooker pushes the sealing plate (6); the sealing plate (6) transfers the power to a transmission part (4); the transmission part (4) drives a corresponding switch device (5). The invention directly pushes the transmission part through the sealing plate with less transmission links, which can improve the sensitivity and the precision of the transmission, thereby controlling the pressure in the cooker precisely. The invention has the advantages of easy making and low cost.

Description

technical field [0001] The invention relates to a safe electric pressure cooker. Background technique [0002] Chinese patent literature, whose application number is 20060057517.X patent document discloses a kind of electric pressure cooker with movable cover, this kind electric pressure cooker comprises pot cover, elastic element, switch, sealing ring, inner pot, electric heater, outer pot, inner pot The edge of the pot sits on the edge of the outer pot; the lid of the pot is sealed with the inner pot through a sealing ring, and the electric heater, switch, and power supply are connected in series; The elastic displacement generated under the internal pressure of the pot controls the on-off of the power switch, and the elastic displacement is transmitted to the corresponding switch through the transmission member arranged at the displacement or static place of the elastic element. The elastic element is arranged on the pot cover and the outside of the pot, and the elastic ...

AI Technical Summary

Problems solved by technology

When making a pot cover, it is necessary to consider not only the rigidity required for the sealing of the pot cover and the pot, but also the elastic deformation capacity of the pot cover. The technical requirements for making a pot cover are relatively high, and the production process is relatively high, and the cost is high.
