Problems solved by technology

[0002] Most residents use liquefied petroleum gas or natural gas for cooking, cooking, and boiling water. During the cooking process, the soup overflows, which is easy to extinguish the gas flame on the stove, causing the gas to leak into the room. It may cause a fire accident, which may cause property damage or endanger life
[0003] Most of the gas alarms sold on the market are installed on the cooker hood on the upper part of the cooker. The detection of gas leakage is limited to the small area of ​​the cooker, and the gas leakage can only be detected when the gas leaks to a certain concentration.

Abstract

The invention discloses a combustible gas and smog leakage reminding device. The combustible gas and smog leakage reminding device is characterized by comprising a 9V direct-current electrical source, a gas detection circuit, a critical value sampling circuit, an astable multivibrator circuit and an audio output circuit. The gas detection circuit is composed of a gas sensor QM and a resistor R1, and the selected model of the gas sensor QM is QM-N6. The astable multivibrator circuit and the audio output circuit are composed of a time-base circuit IC1, a resistor R2, a resistor R3, a capacitor C1 and a piezoelectric ceramic piece HA, and the selected model of the time-base circuit IC1 is NE555. The combustible gas and smog leakage reminding device is a gas leakage warning device with the gas sensor used as a detecting element, the device is suitable for detecting leakage of volatile gas such as natural gas, coal gas, gasoline, carbon monoxide, hydrogen, alkanes and alcohol, and timely detection warning can be conducted on smog formed by fires of wood, paper, woolens, rubber products, plastic products and the like.

Description

technical field [0001] The invention belongs to the technical field of electronics and gas use safety, and relates to a combustible gas and smoke leakage warning device. Background technique [0002] Most residents use liquefied petroleum gas or natural gas for cooking, cooking, and boiling water. During the cooking process, the soup overflows, which is easy to extinguish the gas flame on the stove, causing the gas to leak into the room. It may lead to a fire accident, which may cause property damage or endanger life. [0003] Most of the gas alarms sold on the market are installed on the cooker hood above the cooker. The detection of gas leakage is limited to the small area of ​​the cooker, and it can only be detected when the gas leaks to a certain concentration. [0004] In order to solve or make up for the defects of these gas alarm devices on the market, the combustible gas and smoke leakage alarm device of the present invention uses a gas sensor as a gas leakage alarm...
