Abstract

The invention discloses a control system with a constant-current ripple suppression function and for an air purifying ventilator. The control system is mainly composed of a transformer T, a diode rectifier U, a smoke sensor YW, a triode VT1, a triode VT2, a triode VT3, a triode VT4, a triode VT5, a triode constant-current circuit, a polar capacitor C8, a polar capacitor C9 and a relay K serially connected between P and N poles of a diode D3. Air pollution condition within a using range of the air purifying ventilator can be detected through the smoke sensor YW, detection information can be processed, and control voltage can be adjusted; automatic starting and stopping of the air purifying ventilator can be controlled by controlling the air pollution condition through information detected by the smoke sensor YW.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control system for a purifying air ventilation fan with constant current ripple suppression. Background technique [0002] With the continuous progress of industrial automation and the continuous improvement of people's quality of life, people's requirements for their living environment are also constantly improving, and air quality is an important symbol of the quality of the environment, which directly affects people's healthy life. Air purifiers are used in home, medical, and industrial fields. In the home field, stand-alone household air purifiers are the mainstream products in the market. Air purifiers can remove particulate matter in the air, including allergens, indoor PM2.5, etc., and can also solve the problem of volatile organic compounds in indoors, underground spaces, and cars caused by decoration or other reasons. Therefore people often use air purifier to purify indoor air, a...
