Abstract
The utility model provides a control circuit of a micropower infrared inductive fan, which consists of an LED-based micropower voltage-stabilizing power circuit, an infrared inductive monitoring circuit and a bidirectional controllable silicon alternating current (AC) switch circuit which is coupled and connected with a photoconductive resistor. An infrared inductive function selecting switch is used for automatically supplying the electricity and keeping the time lapse by adopting human body infrared inducting and monitoring, so that an electric fan starts working when a human body moves and automatically stops working when the human body does not move. Therefore, the control circuit reduces the idle power consumption, and is beneficial to managing a sleep power supply and preventing the human body from having a cold caused by the electric fan when sleeping. With the universal components, the control circuit is low in cost, leads the power consumption to be less than 1 milliwatt, and can be widely used for automatically controlling the electric fan.
Description
Affiliated technical field
The utility model relates to a kind of little power consumption infrared induction fan control circuitry, can be widely used in electric fan and control automatically.
Background technique
Electric fan is an electrical equipment commonly used in summer, generally is to adopt power switch control, and people's use habit has caused idle power consumption again, produces the wasting of resources.The current energy-saving low-carbon of advocating requires to provide the fan control of a kind of little power consumption infrared induction.
Summary of the invention
In order to adapt to people's use habit, accomplish the moving electric fan air-supply of people, the quiet autostop of people, the little power consumption infrared induction of the utility model fan control circuitry, automatic power and time-delay keep, and after no human body moved, power supply was closed automatically.Can be widely used in electric fan controls automatically.
The technological scheme that its technical problem that solves the utility model adopts is: little power consumption stabilized power supply of being done benchmark by LED, the little power consumption infrared thermal releasing of BISS001 control circuit, the bidirectional triode thyristor alternating current switching circuit that LED is connected with the photoresistor coupling, electrical equipment or power devices are started by the infrared induction supervisory circuit, export several minutes delay control signal, bidirectional triode thyristor conducting power supply, after no human body moves, power supply is closed automatically, adopt universal component, low power consumption, low cost, little power consumption infrared induction power supply and standby shut-off circuit power consumption are less than 1 milliwatt.
The beneficial effects of the utility model are, the moving electric fan air-supply of people, and the quiet autostop of people reduces idle power consumption, and help simultaneously sleeping power management and electric fan causes when avoiding sleeping human body are suffered from cold.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Among the figure. be the little power consumption infrared induction of the utility model fan control circuitry.
Specific embodiments
Among the figure. circuit is connected with AC network 220V, wherein an end is connected on the controlled fan power supply through bidirectional triode thyristor, the voltage stabilizing power supply of supervisory circuit: little power consumption voltage-stabilized power supply circuit of doing benchmark by LED, circuit is directly connected to ac power supply by 4007 positive poles, the current-limiting resistance R2 ground connection of connecting with two LED pipe D1, D2, the positive pole of D1 connects the NPN transistor base, there is 2uF electric capacity to connect over the ground, current-limiting resistance R 3 connects the NPN transistor collector, launch very circuit output end of pressure-stabilizing, have 470uF electric capacity to connect over the ground.
The infrared induction supervisory circuit: selecting chip BISS001 for use, is the little power consumption infrared thermal releasing of homemade low cost control circuit, has constituted the efficient low-consume function of infrared induction supervisory system.
Time-delay control is by the setting of BISS001 peripheral cell.
The bidirectional triode thyristor alternating current switching circuit that employing is connected with the photoresistor coupling by φ 3 red-light LEDs, 3 elements only, light idol assembly: be by LED and the direct coupling of photoresistor, and with outer light Isolated Shield, the photoresistor two ends directly are connected with bidirectional triode thyristor G end, A2 end, have both simplified the silicon controlled drive circuit, simultaneously because photoresistor is to drive silicon controlled by change in resistance, the characteristic that soft start is arranged helps device power supply (DPS) safety and self alternating current switching circuit safety.
.SW is the infrared induction functional select switch by strong switch among the figure.
Little power consumption infrared induction fan control circuitry is widely used in electric fan and controls automatically.
