Novel wrong gas cut-off prevention electronic safety monitor

Abstract

The invention discloses a wrong gas cut-off prevention electronic safety monitor. According to the electronic safety monitor, not only a stove gas leakage detection sensor is arranged on a stove, but also a gas leakage detection sensor is arranged at a pipeline joint, so that the stove leakage can be detected, the leakage at the pipeline joint can be detected, meanwhile, a leakage point can be accurately determined, and a wrong gas cut-off condition is prevented by repeatedly acquiring the gas concentration at the stove after delaying for a preset time. In addition, by arranging a box for accommodating the sensor at the pipeline joint, the occurrence of the leakage at the pipeline joint can be effectively, timely and accurately detected by the sensor. Thus, the wrong gas cut-off prevention electronic safety monitor has a simple structure and is convenient and concise to implement, indoor gas leakage can be effectively monitored, accidents are avoided, the property safety of the masses of people is protected, and convenience is brought to use of a user.

Description

technical field [0001] The invention relates to a novel household gas electronic safety monitor for preventing miscutting off. Background technique [0002] Gas is a very clean energy that is widely used in today's life. However, the poisoning accidents caused by the leakage of gas have also gradually increased. In order to prevent various accidents caused by leakage, there are various safety detection devices on the market. [0003] Patents such as CN2731213Y have detected the gas leakage on the stove (or stove pan) by arranging devices on the stove (or stove pan) well. But in reality, many gas explosions are not caused by leakage of gas stoves, but because of loose joints at the joints of indoor gas pipelines or aging of connecting materials at joints, which cause gas leakage, causing explosions and other accidents. Therefore, setting the detection device on the cooking range cannot effectively detect the leakage at the joint of the gas pipeline, and some simply cannot d...

Problems solved by technology

This kind of device can better monitor the gas leakage problem, but its disadvantages are also obvious. When a gas leakage occurs, this gas detection device cannot inform the user of the specific location of the leakage, that is, it is not clear whether it is the leakage at the stove or the pipe joint. Leaks everywhere, causing a lot of trouble for repairs

At the same time, because the density of gas is different from that of air, the distribution of gas in the air is not ideally uniform, especially in the case of long-term micro-leakage, the distribution of gas in space is not uniform. When the gas concentration near the detection device is low Being at the preset value does not mean that the gas concentration in all places in the space is lower than the preset value. Therefore, although the detection device does not alarm to remind the gas leak, the gas concentration in some places in the room has reached a dangerous level, causing flash ignition or explosion accident
