Description

Constant pressure valve

Technical Field

The utility model belongs to the technical field of electricity rice cooker, concretely relates to constant pressure valve.

Background

An electric cooker, also called as an electric cooker, is a cooker which converts electric energy into heat energy, has various operation functions of steaming, boiling, stewing and the like on food, and is convenient to use, safe and reliable. The electric cooker not only can cook food, but also can preserve heat, is clean and sanitary when being used, has no pollution, saves time and labor, and is one of indispensable tools for the modernization of housework.

Most of the existing electric cookers are provided with pressure relief valves or constant pressure valves on cooker covers, but some pressure relief valves or constant pressure valves are complex in design structure, and have the problems of inconvenient disassembly, replacement and cleaning. The patent with the application number of CN201811262131.1 discloses a pressure-limiting exhaust device, an electric cooker cover and an electric cooker, wherein the pressure-limiting exhaust device comprises a pressure-limiting valve body and a control component, and the pressure-limiting valve body is connected with an exhaust pipe in a sealing connection mode when in contact; the control part is connected with the pressure limiting valve body through magnetic force, and when the control part is powered on or powered off, the control part can drive the pressure limiting valve body to move in a direction away from or close to the pipe orifice of the exhaust pipe so as to open or close the exhaust passage of the exhaust pipe; the magnetic force between the pressure limiting valve body and the control part is repulsive force. The invention generates magnetic repulsion force when the control component and the pressure limiting valve body are electrified, so that the pressure limiting valve body is pushed to the direction far away from the pipe orifice of the exhaust pipe when the control component is electrified, and the pressure limiting valve body falls back to the pipe orifice of the exhaust pipe under the dead weight when the power is off, thereby realizing the function of controlling the exhaust and pressure relief by magnetic force. The invention controls the movement of the pressure limiting valve body through the magnetic repulsion force, and although the function of controlling the exhaust and pressure relief is realized, the invention still has the problems of complex structure and inconvenient disassembly and cleaning after blockage.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
