Gas-assisted detection device

Abstract

The invention relates to the technical field of safety protection and discloses a gas auxiliary detection device, which includes a bracket and a box body. The box body is fixed on the bracket. The box body is provided with an inner cavity and an air inlet rod; the air inlet rod is equipped with an annular cavity. There is an air inlet on the cavity, a high-pressure air box is fixed on the bracket, baffles and air bags are provided on both sides of the inner cavity, a first sprocket is fixed on the rotating shaft, and an infrared light is installed on the bottom of the baffle; There is an opening and a detection box. The detection box is provided with a first glass plate. There is a photoresistor in the detection box. The photoresistor is electrically connected to an indicator light. The bracket is provided with an internal meshing ratchet structure. The internal meshing ratchet mechanism includes an outer ratchet and an active gear. The pawl, the non-return pawl and the driving wheel. A second sprocket is fixed inside the driving wheel. A turntable is fixed on the outer edge of the outer ratchet. A second glass plate is provided on the turntable, and a transparent tape is provided on the second glass plate. The sticky side of the clear tape faces the lumen. The invention has a simple structure and can detect air without filtering particles.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a gas auxiliary detection device. Background technique [0002] Air, commonly known as "life gas", we need to breathe every day. However, the air contains different amounts of impurities in different environments. These impurities are undoubtedly harmful to the human body. We cannot see them with the naked eye. We need a detection device to detect whether the impurity content in the air is harmful to human health. [0003] Generally, the detection of gas is the detection of PM2.5, and it is believed that PM2.5 is the standard for judging the harmfulness of human body. In fact, large particles of dust exceeding PM2.5 in the air are also harmful to human health. Inhaling too much large particles of dust can also cause respiratory diseases, but the detection of PM2.5 will filter large particles of dust and cannot be clearly detected The content of large particles in the...

Problems solved by technology

In fact, large particles of dust exceeding PM2.5 in the air are also harmful to human health. Inhaling too much large particles of dust can also cause respiratory diseases, but the detection of PM2.5 will filter large particles of dust and cannot be clearly detected The content of large particles in the air

Therefore, the detection of the particle content in the air cannot be filtered, and the detection of particles in the air will be affected after filtering large particles
