TECHNICAL FIELD

[0001] The utility model relates to a gas detection related technical field, specifically to a gas detection device. BACKGROUND

[0002] The gas detection device is a device for monitoring the concentration or composition of gas in the environment. It is usually equipped with high-sensitivity sensors that can detect a variety of harmful gases such as carbon monoxide and hydrogen sulfide in real time and accurately, and issue an alarm. The device is widely used in industrial safety, environmental protection and other fields, effectively preventing gas leakage accidents, and protecting personnel life and property safety and environmental quality.

The driving chip element controls the driving operation of the micro-electromechanical element, the light-emitting element, the particle sensing element, and the gas sensing element respectively, so that the micro-electromechanical element actuates to generate the delivery of the gas, the gas is introduced into the gas detection device through the gas inlet hole of the substrate, and the light spot of the gas is formed by the light source scattered by the light-emitting element. The particle sensing element receives and detects the detection data information of a gas particle, and the gas sensing element detects the detection data information of a gas passing through the gas. Finally, the gas is discharged by the packaging layer.

[0004] The existing gas detection device is prone to accumulate a lot of dust or other stains in the gas inlet pipeline of the detection end after use. If the worker does not clean it in time, the pipeline will be seriously polluted, and the dust and stains in the pipeline will interfere with the normal work of the gas sensor, thereby reducing the accuracy of gas detection. Therefore, we propose a gas detection device. UTILITY MODEL CONTENT
