Description

Technical Field

[0001] The present application relates to the field of concentration detectors, and in particular, to a concentration detector for air pollution sources. Background Art

[0002] Air refers to the mixture of gases in the earth's atmosphere, so air is a mixture. It is mainly composed of nitrogen, oxygen, rare gases, carbon dioxide and other substances (such as water vapor, impurities, etc.), of which the volume fraction of nitrogen is about 78%, the volume fraction of oxygen is about 21%, the volume fraction of rare gases is about 0.934%, and the volume fraction of carbon dioxide is about 0.04%. There are also some other particles in the air. An air particle concentration detector is needed in the process of detecting the concentration of these particles.

[0003] The structure of the product can refer to the air particle concentration detector disclosed in Chinese patent document 2020206977232, which includes a body, an air inlet, a control switch, a heat dissipation hole, a power cord, an indicator light and a display screen. A purification device is arranged at the lower end of the body, and air is introduced into the shell through the air duct. The HEPA filter layer and the activated carbon layer are used to absorb odor and other particles in the air. A quick disassembly mechanism is arranged at the bottom of the sealing ring. When disassembly is required, the pressing piece is pressed down to make the pressing piece slide downward on the outer surface of the mounting piece. The pressing piece squeezes the spring piece to separate the spring piece from the card piece, and then the shell and the sealing ring are removed, the connecting cover is screwed off, the fixing frame is pulled out of the shell, and then the HEPA filter layer and the activated carbon layer are removed for cleaning. The device is easy to use and simple to operate, and effectively solves the problems of poor evolution effect of the introduced gas and troublesome disassembly of the shell of traditional air particle concentration detectors.

[0004] When conducting atmospheric concentration detection, the atmosphere needs to be sucked in and then put into detection. However, this patent does not have the function of filtering the sucked atmosphere, so that the air is still discharged, affecting the environment.

[0005] A concentration detector for an air pollution source is now provided. Summary of the invention
