Portable air pollution detection device

Abstract

The invention discloses a portable air pollution detection device, which comprises a casing, a button group, an outer cover, a handle, a pull ring, a filter screen, screws, fixing holes, a collection box, an air pipe, a motor, a bellows, an electrostatic adsorption plate, a brush and storage tube. The beneficial effect of the present invention is: by installing a layer of filter screen on the outer cover of the device, the device can pre-filter the inhaled air when detecting the air quality, so that only small particles such as dust in the air can be inhaled. The device is small in size, and a handle is installed on one side of the shell, and a pull ring is installed on the side of the bellows, so that the device is light in weight and easy to carry. The device adopts electrostatic adsorption, and removes the adsorbed dust and dust with a brush and collects them inside the bellows. The air quality is judged by detecting the amount of dust collected inside the bellows. The device does not need to be disassembled and cleaned after use, which is more convenient to use.

Description

technical field [0001] The invention relates to a portable air pollution detection device, which belongs to the field of air pollution detection. Background technique [0002] Air detection in a broad sense refers to the detection of air components, and air detection in a narrow sense is mainly from the perspective of application, focusing on the detection of dust in the air. Air quality testing is an emerging industry. It is a technical process of analysis and testing for air pollutants exceeding the standard. According to the test result value, a nationally recognized and legally valid test report is issued. According to the air quality standard, it can be judged The pollution status of various indicators in the air, and carry out targeted prevention and control measures. [0003] However, the existing air pollution detection devices still have certain defects in use. Generally, the quality of control is judged by detecting the content of dust in the air, and it is often ...

Problems solved by technology

[0003] However, the existing air pollution detection devices still have certain defects in use. Generally, the quality of control is judged by detecting the content of dust in the air, and it is often necessary to constantly move the position of the detection device during detection to accurately judge the air quality of the environment in an all-round way. , and the existing air pollution detection device has the disadvantage of being inconvenient to carry, and the inside of the air pollution detection device needs to be cleaned once after each detection, which is troublesome
