Abstract

The invention discloses a control system for a purifying air ventilation fan with a constant current type voltage stabilizing filter. VT3, transistor VT4, transistor VT5, relay K, polar capacitor C10, polar capacitor C12, resistor R7, resistor R8, adjustable resistor R9, resistor R10, resistor R11, resistor R12, and P pole connected in series with diode D3 It is composed of the relay K between the N pole and so on. The present invention can detect the air pollution within the scope of use of the purifying air ventilation fan through the smoke sensor YW, and can process the detected information, and adjust the control voltage, and the present invention can pass the information detected by the smoke sensor YW To control the air pollution situation to control the automatic opening and closing of the purifying air ventilation fan.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control system for a purifying air ventilation fan with a constant current type voltage stabilizing filter. 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 purif...
