Problems solved by technology

[0003] Most of the existing air sampling devices do not have the pretreatment function and cannot dehumidify the sample air, resulting in low accuracy of the air detection results. At the same time, the existing air sampling devices do not have the function of conveniently replacing the filter screen. After use, the air filter tends to accumulate a large amount of dust, which affects the air filtration effect. Moreover, most of the existing air sampling devices do not have the data recording function, so that the staff need to manually record the detection data at different locations and times, resulting in The convenience of use is low, so there is an urgent need for an ambient air sampling device with a pretreatment structure to solve the existing problems

Abstract

The invention discloses an ambient air sampling device with a pretreatment structure, the ambient air sampling device comprises a box body, an air inlet pipe, a dehumidification cavity and a detection cavity, both sides of the upper end of the box body are provided with grips, and the middle part of the upper end of the box body is provided with a display panel. The device has the beneficial effects that through the design of the dehumidification cavity, the refrigerator and the condensation plate, the air sampling device can have a pretreatment function, sample air can be dehumidified, and therefore the accuracy of an air detection result is improved, the air inlet pipe, the filter screen and the lifting handle are arranged, the air sampling device can have the function of conveniently replacing the filter screen, the air filter screen can be rapidly replaced after repeated use, so that the influence on the air filtering effect is avoided, the air sampling device can have the data recording function through the design of a laser receiver and a data storage hard disk, detection data of different places and time can be automatically recorded, and the use convenience of the device is improved.

Description

technical field [0001] The invention relates to the technical field of air sampling, in particular to an ambient air sampling device with a pretreatment structure. Background technique [0002] Ambient air quality is a standard formulated to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on Air Pollution Prevention and Control", protect and improve the living environment, ecological environment, and safeguard human health. Sample collection was performed using an ambient air sampling device. [0003] Most of the existing air sampling devices do not have the pretreatment function and cannot dehumidify the sample air, resulting in low accuracy of the air detection results. At the same time, the existing air sampling devices do not have the function of conveniently replacing the filter screen. After use, the air filter tends to accumulate a large amount of dust, which affects the air filtration effe...
