Abstract

The invention discloses an indoor formaldehyde content detection device and a use method thereof, and belongs to the field of formaldehyde detection. According to the indoor formaldehyde content detection device and the use method thereof, in the scheme, a formaldehyde purification device rotates in a base by switching on a power supply and turning on a motor; a detection direction is adjusted, alight receiving rate in the formaldehyde purification device is improved through strip-shaped light inlet holes; light enters the formaldehyde purification device through the strip-shaped light inletholes, and a temperature in the formaldehyde purification device is increased through sunlight; a shape of a shape memory spring in a support tube is changed through a temperature change; a telescopicrod enables a top block to slide up and down in the support tube through the shape memory spring to extrude a hydroxylamine phosphate solution; and the hydroxylamine phosphate solution is dispersed into a connecting tube through the formaldehyde detection device, enters chromogenic adsorption cotton and is mixed with formaldehyde ions in adsorption holes to change colors so that the detection offormaldehyde in the air is directly observed.

Description

technical field [0001] The invention relates to the field of formaldehyde detection, and more specifically relates to an indoor formaldehyde content detection device and a use method thereof. Background technique [0002] Acute formaldehyde poisoning is manifested as irritation to the skin and mucous membranes. Inhalation of high concentrations of formaldehyde can cause respiratory irritation symptoms, sneezing, coughing with burning sensation in the nose and throat; in addition, it can also induce bronchial asthma, pneumonia, pulmonary edema A large amount of formaldehyde intake through the digestive tract at one time can cause symptoms of digestive tract and systemic toxicity, corrosive burns of the mouth, throat and digestive tract, abdominal pain, convulsions, death, etc. Skin contact with formaldehyde can cause allergic dermatitis, stains, Skin necrosis and other lesions, oral ingestion of 10-20ml formaldehyde solution can be fatal. [0003] Formaldehyde has many uses ...
