Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of security equipment, specifically relates to a nickel-saving type stainless steel air quality early warning civil air defense door. BACKGROUND

[0002] The civil air defense door is the door of the entrance and exit of the people's protective engineering, and is the earliest type of door, which has been widely selected, and has the characteristics of simple structure, reliable operation, convenient maintenance and application to the entrance and exit of various civil air defense engineering.

[0003] However, the civil air defense door is generally airtight and not breathable, and the people inside the civil air defense door cannot effectively understand the situation outside because the four sides of the door are all walls. Therefore, when there is toxic and harmful gas outside the civil air defense door, the people inside cannot fully understand the specific situation of the air quality outside through the civil air defense door, and if the door is opened recklessly, unnecessary loss will be caused.

[0004] Therefore, some civil air defense doors are provided with air detection and early warning devices, which mainly comprise a ventilation hole channel formed on the door body, a detection mechanism and a valve. The detection mechanism is in communication with the ventilation hole channel, and the valve is used to control the on-off of the ventilation hole channel and the detection mechanism. When it is necessary to detect the air quality outside, the valve controls the ventilation hole channel to be in communication with the detection mechanism, and the air outside enters the detection mechanism for detection.

[0005] However, the port of the ventilation hole channel is usually directly formed on the outer surface of the door body, so that the ventilation hole channel is in communication with the outside for a long time, and dust and other impurities and garbage are easily deposited inside, thereby causing the ventilation hole channel to be blocked and affecting use.
