Indoor air quality detection device

Abstract

The invention relates to an indoor air quality detection device. The indoor air quality detection device comprises an air collecting bottle, wherein a motor is fixedly arranged at the top surface of the inner wall of the air collecting bottle; an output shaft of the motor faces down, and fan blades are fixedly arranged at the output shaft of the motor; electrode plates are respectively fixedly arranged at both sides of the motor, and are respectively connected with a positive electrode wiring point circuit and a negative electrode wiring point circuit of the motor; guide sleeves are respectively fixedly arranged at both sides of the back surface of the inner wall of the air collecting cylinder through fixed frames; the centerlines of the two guide sleeves are positioned on one line, and are respectively vertical to one side of the air collecting cylinder; a movable rod is arranged in each guide sleeve, and penetrates through the corresponding guide sleeve; the periphery of each movablerod is in contact fit with the inner wall of the corresponding guide sleeve. The indoor air quality detection device has the advantages that the size of indoor space is not limited; when the indoor space is larger, a flexible pipe is longer, and the period of air entering the air collecting cylinder until the motor stops work is longer; when the indoor space is smaller, the flexible pipe is shorter, and the period of air entering the air collecting cylinder until the motor stops work is shorter; the application range is broader.

Description

technical field [0001] The invention belongs to the field of environment detection, in particular to an indoor air quality detection device. Background technique [0002] Indoor air testing is based on indoor air quality standards, which can determine the pollution status of various indicators in the room and carry out targeted prevention and control measures. With the increase of people's attention to air quality, indoor air testing has developed into a new industry, which can issue nationally recognized and legally valid test reports based on the test results. However, because it is too professional and cumbersome, if people want to know the indoor air quality, they cannot find professionals for quality inspection every time. There are also some air quality detectors on the market, but they are often large in size and will cause problems. It occupies a large indoor space, and if the indoor space is large, it is necessary to move the detector to perform multiple detections...

However, because it is too professional and cumbersome, if people want to know the indoor air quality, they cannot find professionals for quality inspection every time. There are also some air quality detectors on the market, but they are often large in size and will cause problems. Occupies a large indoor space, and if the indoor space is large, it is necessary to move the detector to perform multiple detections and calculate the average value to obtain a more accurate air quality index, which is extremely inconvenient in actual use
