Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas detection, and specifically relates to a combustible gas detector. Background Art

[0002] Combustible gas detectors are important safety devices widely used in industrial, commercial and household environments. Commonly, they are mostly installed in a wall-mounted or fixed manner.

[0003] They detect the concentration of combustible gas in the air through built-in sensors. Once the concentration exceeds the safety threshold, an alarm will be triggered to prevent the occurrence of fire or explosion accidents. However, during actual use, combustible gas detectors often have their air inlets blocked by impurities such as dust and oil stains due to long-term exposure to complex environments, thus affecting their detection accuracy and sensitivity. This problem not only reduces the reliability of the detector but also may pose potential safety hazards. Therefore, a combustible gas detector is proposed to solve the above-mentioned problems.
