An automatic detection device for vehicle-mounted formaldehyde exceeding the standard

Abstract

The invention discloses a vehicle-mounted formaldehyde standard exceeding automatic detection device. The detection device comprises an upper shell and a lower shell; a bottom cover is buckled at thebottom of the lower shell; a bottom plate is fixedly mounted at the bottom of the bottom cover; a supporting frame is arranged on the inner side of the bottom cover; an air guide plate is arranged above the supporting frame; a first mounting base is mounted on the inner side of the lower shell; a photoelectric detection module is mounted in the middle of the upper shell; a second mounting base ismounted above the upper shell; and an accommodating groove is formed in the second mounting base. In a detection process, formaldehyde in air and a detection solution react in a closed transparent detection box, so that the interference of the outside air is avoided, and the detection precision is high; the air guide plate is arranged, so that the air can uniformly rise and enter the upper shell,and the success rate of sampling the air by an exhaust fan is guaranteed; and mounted parts in the detection device are kept stable, the detection device is convenient to mount and dismount, the detection solution can be replaced conveniently, and the detection device is compact in structure, relatively small in size and suitable to be vehicle-mounted.

Description

technical field [0001] The invention relates to the technical field of air detection equipment, in particular to a vehicle-mounted automatic detection device for formaldehyde exceeding the standard. Background technique [0002] With the prosperity of the decoration industry, the problem of indoor pollution has been brought along. Formaldehyde is an important pollutant in indoor air. The main hazard of formaldehyde is the stimulation of skin and mucous membranes. The formaldehyde content of the furniture is high, which is the main cause of many diseases. Formaldehyde is a colorless and soluble irritating gas. Formaldehyde is pervasive. Some formaldehyde detection devices are susceptible to external interference during detection and sampling, and the detection accuracy is low; [0003] The patent document (CN109668880A) provides a formaldehyde detection device, which belongs to the technical field of formaldehyde detection, which includes: a sampling device, a detection cont...

AI Technical Summary

Problems solved by technology

[0005] By setting the air guide plate on the inner side of the lower casing, the air entering the detection device passes through the uniformly dense air guide holes during the rising process, so that the air rises evenly into the upper casing, ensuring that the air passes through the air inlet of the exhaust fan evenly, thereby ensuring Improve the success rate of air sampling by the exhaust fan, and solve the technical problems of inconvenient sampling and low sampling success rate of the existing formaldehyde detection device;

[0007] The flip cover on the top of the detection device can be flipped open, which is convenient for regular replacement of the detection solution inside the transparent detection box. The detection device is compact in structure and small in size, which solves the problem that the detection solution of the existing formaldehyde detection device is not easy to replace, large in volume, and difficult to replace.
