Pressure alarm device for electric pressure cooker and method for using same

Abstract

The invention discloses a pressure alarm device for an electric pressure cooker and a method for using the same. The pressure alarm device comprises a base and an outer casing, wherein a spacing bossis arranged above the base, and the outer casing is arranged above the spacing boss. The top of the outer casing is provided with a transparent protective cover, the upper side surface of the outer casing is provided with a display screen casing, the display screen casing is provided with a liquid crystal display, and the rear side of the liquid crystal display is provided with a backlight set. The beneficial effects are as follows: 1. the temperature and pressure information inside the electric pressure cooker can be automatically monitored and displayed, which is convenient for the user to check the use condition of the electric pressure cooker; 2. the pressure can be automatically relieved to avoid the danger of excessive internal pressure of the electric pressure cooker, and the pressure is released, an alarm signal is sent to facilitate the user to find out in time; 3. when the electric pressure cooker is powered off, the internal condition of the electric pressure cooker can be continuously monitored to avoid danger; and 4. the temperature of hot air discharged during the pressure relief can be reduced to avoid scald accidents, and the security is good.

Description

technical field [0001] The invention relates to the technical field of pressure cookers, in particular to a pressure alarm device for an electric pressure cooker and a use method thereof. Background technique [0002] Electric pressure cooker is an upgraded product of traditional pressure cooker and electric rice cooker.
