Abstract

The invention discloses measuring equipment for formaldehyde in ambient air, which comprises a device box and a mounting bin, a connecting pipe penetrating through the side walls of the two ends is mounted in the device box, a fixing plate is mounted in the connecting pipe, a first filter screen is arranged in the fixing plate, a first heat dissipation fan is mounted in the connecting pipe, and a second filter screen is mounted in the first heat dissipation fan. A storage box is installed at the bottom end of the interior of the device box, a fixing frame is installed at the top end of the storage box, a supporting plate is installed at the top end of the fixing frame, a threaded hole is formed in the supporting plate, and a ventilation pipe is installed at the top end of the device box. According to the equipment for measuring the formaldehyde in the ambient air, the scraper main body is attached to the first filter screen, so that dust and batting adhered to the first filter screen can be cleaned while the scraper main body rotates, and the situation that the dust and batting enter the device box through the connecting pipe, and consequently the formaldehyde measuring result is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of formaldehyde detection, in particular to equipment for measuring formaldehyde in ambient air. Background technique [0002] Formaldehyde is a colorless, water-soluble liquid that is highly volatile and has a pungent odor. Indoor formaldehyde mainly comes from building materials, furniture, wood-based panels, various adhesive coatings and synthetic textiles, etc. The amount of formaldehyde is very small. After the house is decorated, the ambient air inside the house will contain a large amount of formaldehyde. After formaldehyde is absorbed by the human body, it will cause certain harm to the human body. Therefore, after the house is decorated, it is necessary to clean the ambient air. To detect the formaldehyde in the air, to detect the formaldehyde content in the ambient air, when the formaldehyde is detected, it is necessary to pass the formaldehyde measurement equipment, the traditional formaldehyde me...
