Background technique
Heat summer, the weather sweltering heat, people have to look for nice and cool place to be had a rest or work, big city office or house generally all adopt air conditioner refrigerating now, adopt air-conditioning to regulate room temperature, no doubt can give nice and cool impression, but, grown in the air-conditioned room time, people be easy to air-conditioning sickness, the heart of feeling to have a headache is vexed; In addition, use air-conditioning for a long time, make room air pollution, contract a contagious disease easily, especially in the place of the shared office of many people; So, more and more people begin to return, use electric fan, but be to use electric fan, exist one to hold the problem that the people is fallen ill in bed as the people again, well-known, the people passive protective physical fitness in bed a little less than, use the common electrical fan to aim at the long-term blowing continuously of human body, therefore the people can be easy to take place cold, especially all the more so to baby or child.
Summary of the invention
The technical problem that the utility model solves is to overcome above-mentioned shortcoming, and providing a kind of can discharge ultrared power according to human body, releases infrared induction and controls electric fan automatically and control people's body heat that electric fan starts or stops automatically.
The technical solution of the utility model is: adopt passive human body heat to release infrared inductor PIR and control intergrated circuit, utilize people's body heat to release infrared induction and control electric fan automatically, when human body was motionless, people's body heat was released infrared induction and is controlled electric fan automatically and can not rotate; When person heating, the person will stir, at this moment, people's body heat is released the infrared induction control circuit and is detected the saltus step heat that human body sends automatically and release infrared signal, and starts electric fan, gives body temperature lowering, meanwhile, intergrated circuit output control time-delay picks up counting, and when arriving the delay time of setting, electric fan quits work again automatically.
A kind of people's body heat that the utility model provides is released infrared induction and is controlled electric fan automatically, the supporting element that comprises fans, fan electromotor and supports fan motor, band passive human body heat is installed on described supporting element releases the control circuit of infrared inductor, described control circuit connects in the power circuit of fan electromotor.
Described control circuit is serially connected in the circuit of the weak wind shelves of electric fan, apoplexy shelves or high wind shelves.
Described control circuit is serially connected among the electric fan gear control total input-wire.
At described control circuit output terminal and be connected to hand switch.
The utility model is equipped with the control circuit that band passive human body heat is released infrared inductor owing to having adopted on described supporting element, structure in the power circuit of described control circuit serial connection fan electromotor, like this, just solved the long-term blowing continuously of use common electrical fan well, therefore the people can be easy to take place the problem of cold.In addition, user's body heat is released infrared induction and is controlled electric fan automatically and can not change air quality, can overcome the problem that air-conditioning reduces the discharge value of airborne moisture content and natural air.
In addition, the utility model also has the advantage of economize on electricity, and fan can be because of nobody closes continuous rotation power consumption for a long time; When it for air-conditioning, its power savings is just self-evident.
