Abstract

The invention discloses a voltage constant current adjustment control system for a purifying air ventilation fan, which mainly consists of a voltage stabilizing chip U2, a smoke sensor YW, a triode VT1, a triode constant current circuit, a triode VT2, a triode VT5, a relay K, a resistor R9, a resistor R10, adjustable resistor R11, polar capacitor C4, polar capacitor C5, polar capacitor C6, polar capacitor C7, polar capacitor C8, polar capacitor C9, diode D3, diode D4, diode D5, and connected in series The relay K between the P pole and the N pole of the diode D2 is composed of the relay K and the like. The present invention can detect the air pollution within the use range of the purified air ventilation fan through the smoke sensor YW, and can process the detected information and adjust the control voltage, and the present invention can use 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 voltage constant current adjustment control system for a purifying air ventilation fan. 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, and wh...
