Novel high-pressure sensor and electric pressure cooker

Abstract

The invention relates to the technical field of novel high-pressure detection devices, in particular to a novel high-pressure sensor and an electric pressure cooker. The pressure sensor comprises a body seat, wherein an air inlet is formed in the upper part of the body seat and communicated with an inner cavity in the body seat, a piston is arranged in the inner cavity, and the outer wall of the piston is tangent to the inner wall of the inner cavity; a magnetic ring is arranged on the piston, and an adjusting piece is arranged at an opening in the bottom of the inner cavity; an elastic pieceis abutted between the piston and an adjusting screw, and a coil is arranged on the outer side of the inner cavity and connected with a circuit. The pressure sensor is directly communicated with the inside of the electric pressure cooker, pressure inside the electric pressure cooker is measured directly, so that safety of the electric pressure cooker can be improved, the pressure can be automatically adjusted according to the pressure values required for cooking different kinds of food, and more tasty and more delicious food can be cooked.

Description

technical field [0001] The invention relates to the technical field of pressure detection devices, in particular to a novel high-pressure pressure sensor and an electric pressure cooker with the pressure detection device. Background technique [0002] The electric pressure cooker is a common kitchen pot on the market. Through the physical phenomenon that the boiling point of the liquid will be raised under higher pressure, the pressure is applied to the water so that the water can reach a higher temperature without boiling to speed up the stewing. Food efficiency. And each electric pressure cooker all has the maximum pressure value that can bear inside, when its internal pressure exceeds this maximum pressure value, just prone to explosion accident; More precise detection and control of the pressure is needed to cook more delicious food. However, the electric pressure cookers on the market today are generally only equipped with temperature sensors. Based on the roughly corr...

Problems solved by technology

And each electric pressure cooker all has the maximum pressure value that can bear inside, when its internal pressure exceeds this maximum pressure value, just prone to explosion accident; More precise detection and control of the pressure is needed to cook more delicious food. However, the electric pressure cookers on the market today are generally only equipped with temperature sensors. Based on the roughly corresponding relationship between the detected temperature and pressure in the pot, it is possible to calculate The internal pressure of the electric pressure cooker, but because it does not directly measure the pressure inside the pot, it is greatly affected by various external conditions; for example, different foods and different amounts will greatly affect the accuracy of the pressure Judgment, which will affect the taste of delicious food, and even constitute a safety hazard if the situation is serious
