Description

Technical Field

[0001] The utility model relates to the technical field of air quality detection, in particular to a timing extraction device for air quality detection. Background Art

[0002] Air quality testing refers to testing the quality of air. The quality of air reflects the concentration of pollutants in the air. Air pollution is a complex phenomenon. The concentration of air pollutants at a specific time and place is affected by many factors. The emission of man-made pollutants from fixed and mobile pollution sources is one of the most important factors affecting air quality, including exhaust from vehicles, ships, aircraft, industrial production emissions, residents' living and heating, garbage incineration, etc. The development density of the city, topography and meteorology are also important factors affecting air quality.

[0003] Atmospheric sampling refers to the method of collecting pollutant samples or polluted air samples in the atmosphere. One type of collection method is to pass a large amount of air through a liquid absorbent or solid adsorbent to enrich the pollutants with lower concentrations in the atmosphere, such as the vacuum method and the filter membrane method. The other type is to use containers (glass bottles, plastic bags, etc.) to collect air containing pollutants.

[0028] The insect killing mechanism includes a lampshade 02, a mosquito-attracting lamp tube 03 and an electric mosquito net 04. The lampshade 02 is fixedly connected to the top of the mounting plate 06, the electric mosquito net 04 is laid on the surface of the lampshade 02, and the mosquito-attracting lamp tube 03 is fixedly connected to the center of the lampshade 02.

[0029] In the present embodiment, preferably, a vacuum pump 10 is fixedly connected to one end of the inner bottom wall of the base 05, a vacuum pipe is fixedly connected to the top of the vacuum pump 10, and a gas pipeline 12 is fixedly connected to one side of the vacuum pump 10. When in use, the vacuum pump 10 mixes and collects the air collected by each sampling pipeline 11 through the vacuum pipe, so that the air in the same detection environment at the same time period can be evenly mixed, which is convenient for later detection.

[0030] In this embodiment, preferably, the other end of the inner bottom wall of the base 05 is fixedly connected to an air box 13, one end of the air box 13 is fixedly connected to a gas pipeline 12, and one end of the gas pipeline 12 is fixedly connected to an air pump 10.
