Problems solved by technology

[0006] However, the existing hypoxia protection device detects whether the surrounding oxygen concentration is too low through the mechanism design of magnetic force and elastic force. After a period of time, it is prone to elastic fatigue, which will greatly reduce the accuracy of the hypoxia protection device, thereby affecting the safety of users

Abstract

A hypoxia protection device is used for regulating supplied gas quantity when oxygen concentration around a gas burning device is lower than a preset value and comprises an electric gas valve, a thermal couple and a controller, wherein the electric gas valve is used for controlling gas flow supplied to the gas burning device. The thermal couple is arranged nearby the gas burning device and outputs thermoelectric force according to thermal energy generated by the gas burning device. The controller is electrically connected with the electric gas valve and the thermal couple and used for receiving the thermoelectric force, calculating whether the oxygen concentration around the gas burning device is lower than the preset value according to the thermoelectric force and generating an electric signal to control the electric gas valve to regulate gas supplied to the gas burning device when the oxygen concentration is lower than the preset value.

Description

technical field [0001] The present invention is related to a gas device, and more specifically refers to a hypoxia protection device. Background technique [0002] The most common accident when using gas burning appliances (such as water heaters, gas stoves, fireplaces, etc.) is carbon monoxide poisoning, and carbon monoxide poisoning refers to the incomplete combustion of oxygen due to insufficient oxygen in an unventilated environment, which in turn produces toxic gases A buildup of carbon monoxide, an accident in which people inhale carbon monoxide without knowing it. [0003] When gas burners are in use, full mixing of gas and oxygen is the basic requirement for effective combustion. When it is completely burned, the carbon and hydrogen contained in it will become carbon dioxide and water, and when it is incompletely burned, it will produce Toxic carbon monoxide, especially in the case of insufficient oxygen, the incomplete combustion situation is more serious, and in w...
