AI Technical Summary
Technical Problem
Existing indoor air chemical pollution detection devices require compressed air to be discharged before the next test can be performed, resulting in low detection efficiency.
Method used
It employs an alternating air intake mechanism and a reciprocating drive assembly, using the cooperation of a square hollow column and a piston to achieve alternating air intake and exhaust, thereby increasing air concentration and reducing the possibility of repeated detection. Combined with a guide fan and guide tube, it increases the airflow range.
Benefits of technology
It improves the accuracy and efficiency of indoor air chemical pollution detection, reduces wasted time, and lowers the possibility of repeated testing.

Abstract
The application relates to the technical field of air pollution detection, and discloses an indoor air chemical pollution detection device, which comprises a square hollow column, a baffle is fixedly arranged in the square hollow column, alternating air inlet mechanisms are arranged at the positions of the two sides of the baffle in the square hollow column, a detection box is fixedly arranged at the upper end of the square hollow column, an exhaust pipe is fixedly inserted into the lower end of the side wall of the detection box, a first pressure valve is arranged in the exhaust pipe, a mounting hole is arranged in the end surface of the detection box, and a formaldehyde detection mechanism is inserted into the mounting hole. The compressed air can improve the air concentration of detection, improve the detection accuracy, reduce time waste, improve the overall efficiency, increase the air circulation detection range, avoid inhaling the detected air as much as possible, and reduce the possibility of repeated detection.
