Description

Technical Field

[0001] The utility model relates to the field of gas alarm equipment, in particular to a gas alarm with a positioning function. Background Art

[0002] A gas alarm is a gas leak detection alarm instrument. When it detects that the gas concentration has reached the critical point of explosion or poisoning, it will send out a signal to remind people to take measures. Its function is to prevent accidents such as fire, explosion and poisoning, and improve the safety of homes and industrial production. The core of the gas alarm is the gas sensor, commonly known as the "electronic nose". When it "smells" the gas, the sensor resistance changes with the gas concentration. When the gas reaches a certain concentration and the resistance reaches a certain level, the alarm will send out an audible and visual alarm. Some alarms can also be linked with the electromagnetic shut-off valve, which can automatically close the gas valve when an alarm is triggered to prevent further gas leakage.

[0003] When installing and positioning existing gas alarms, they are generally fixed to the wall by suction cups or bolts. However, when using a suction cup for installation, when the suction cup is pressed against the wall, the air in the suction cup is discharged, forming a vacuum environment. Due to the effect of atmospheric pressure, the external air pressure will produce pressure on the suction cup, causing a large pressure difference between the suction cup and the wall, thereby generating adsorption force. However, after the suction cup has been used for a long time, dust will clog the small holes at the bottom of the suction cup, thereby affecting the adsorption force of the suction cup. When using bolts for installation, other tools are required for installation. Such operation is more complicated and affects work efficiency.

[0004] Therefore, it is necessary to provide a new gas alarm with a positioning function to solve the above technical problems. Utility Model Content
