Description

Technical Field

[0001] The utility model relates to the technical field related to air quality detection, and in particular to an air quality detection alarm structure. Background Art

[0002] To ensure safety, it is usually necessary to install air detection alarms indoors to detect toxic gases or flammable and explosive gases. When the gas alarm detects certain toxic gases or flammable and explosive gases such as coal gas and natural gas, the alarm will send out an alarm signal to remind workers to take safety measures to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. During the use of the detection alarm, in order to ensure sufficient contact with the air, it is usually exposed to the external environment. However, the existing device lacks a structure on the inside to provide protection for the alarm, which may cause the alarm to collide with external objects and cause structural damage, thereby affecting the overall operation of the device.

[0003] To this end, we propose an air quality detection alarm structure to solve the above problems. Utility Model Content
