Abstract
An induction electronic fan is provided. A human body infrared inducer which is used to control the switch of the fan and a control circuit are installed in the fan. When people leave, the fan automatically stops, and fan can automatically start when people approach. The device avoids unnecessary waste.
Description
Technical field
The utility model relates to domestic electric fan, is a kind of human body infrared induction electric fan specifically.
Background technique
At present, domestic electric fan is to control with hand switch and time switch, when the people leaves, and, if forgotten the pass power supply, electric fan can continue to fan or till the time switch time arrives, cause unnecessary waste.Particularly in unexpected power failure, do not close when the people walks, wait the people to walk after again under the situation of incoming call, this waste is more serious.
Summary of the invention
The purpose of this utility model provides a kind of human body infrared induction electric fan, and when the people left, electric fan stopped automatically, when the people near the time, electric fan can be opened automatically.
The purpose of this utility model is achieved in that inductive electric fan, the human body infrared inductor of installation and control Switch for electric fan in electric fan.The inductor control circuit is installed in electric fan.
The beneficial effects of the utility model are: avoid some wastes.
Description of drawings
Fig. 1 is the utility model electric fan schematic representation.
Fig. 2 is the utility model electric fan circuit diagram.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
Among the figure: 1 human body infrared inductor, 2 inductor switches, 3 electric fan driving switch, 4 power supplys, 5 electric fan motor.
Referring to Fig. 1, the human body infrared inductor is installed in the central position of electric fan, and the direction of its induction is always towards the front of electric fan.Here the just table fan of drawing, claim of the present utility model is applicable to the domestic electric fan of form of ownership.
Referring to Fig. 2, inductor switch 2 is pulled from inductor 1, promptly turn off the inductor switch, the human body infrared inductor is inoperative; Inductor switch 2 is pulled inductor 1 this side, promptly open the inductor switch, electric fan driving switch 3 closes, at this moment power supply 4, human body infrared inductor 1, electric fan motor 5 have been formed a closed circuit, the human body infrared inductor is started working, in the certain limit of electric fan front man-hour is arranged, inductor will remain closed the connection of circuit, and electric fan is opened; During the no one of electric fan front, inductor can disconnect closed circuit, forces electric fan to quit work.
Claims (1)
1. an inductive electric fan is characterized in that: the human body infrared inductor that the control Switch for electric fan is installed in electric fan.
