Description

technical field [0001] The invention relates to a purifier; in particular, it relates to a household air biological purifier and its control circuit and control method. Background technique [0002] In the fabric production process, in order to achieve anti-wrinkle, anti-shrinkage, flame retardant, etc., or to maintain the durability of printing and dyeing, or to improve the hand feel, formaldehyde needs to be added to the additives. Pure cotton textiles are mostly used as formaldehyde printing and dyeing auxiliaries, because pure cotton textiles are easy to wrinkle, and the use of formaldehyde-containing auxiliaries can improve the stiffness of cotton cloth. Textiles containing formaldehyde will gradually release free formaldehyde during people's use. The main hazard of formaldehyde is the stimulation of skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable; more than 0.08mg / m 3 High formaldehyde concentration ...
