Summary of the invention
The purpose of the utility model is in order to overcome deficiency of the prior art, a kind of energy-conservation wall fan that can regulate power automatically to be provided, and whether this scheme uses human inductor human body to exist; To change circuit structure; Regulate output power, realize under the unmanned situation, reduce output power automatically; Thereby energy saving increases output power automatically and have under people's situation.
The utility model solves the technological scheme that its technical problem adopted:
Can regulate the energy-conservation wall fan of power automatically, comprise base, motor; Fan blade; Guard is installed in speed governing pull switch and head-shaking switch on the described base, is installed in the inner control circuit of described base; Also comprise the human inductor that is arranged on the described guard, described human inductor is connected with described control circuit.
Described speed governing pull switch is set to zero-span, first gear, second gear, third gear and fourth speed position.
Described human inductor comprises Fresnel lens, pyroelectric sensor, signal processing circuit and output switch.
Described control circuit comprises and parallel first resistance that is connected of described human inductor; One end of described first resistance is connected with safety fuse cutout with silicon controlled first port; The other end is connected with second resistance; The other end of described second resistance connects charging capacitor and bidirectional trigger diode; The other end of described bidirectional trigger diode connects the said silicon controlled control utmost point, and the other end of described charging capacitor is connected with the live wire of said silicon controlled second port with the input power supply, and described safety fuse cutout connects with the common port of described speed governing pull switch; The output terminal of described speed governing pull switch is connected with described motor, and the other end of described motor connects the zero line of described input power supply.
Whether the beneficial effect of the utility model mainly shows: 1, use the human inductor human body to exist, to change circuit structure, regulate output power; 2, detect after the human body, working power is adjusted to maximum, and under the unmanned situation, power adjustments is to minimum, and is convenient and practical.
Description of drawings
Fig. 1 is the outline drawing of energy-conservation wall fan;
Fig. 2 is the control structure figure of energy-conservation wall fan;
Fig. 3 is the schematic diagram of human inductor.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
With reference to Fig. 1-3, can regulate the energy-conservation wall fan of power automatically, comprise base 1; Motor 2, fan blade 3, guard 4; Be installed in speed governing pull switch 5 and head-shaking switch 6 on the described base 1; Be installed in the control circuit of described base 1 inside, also comprise the human inductor 7 that is arranged on the described guard 4, described human inductor 7 is connected with described control circuit.
Wherein, described speed governing pull switch 5 is set to zero-span, first gear, second gear, third gear and fourth speed position, and zero-span is represented power-off, the rotation speed of the fan that other gears are corresponding different respectively.Voluntarily whether the described energy-conservation wall fan of described head-shaking switch 6 controls swing, the adjustment air supply direction.
Described human inductor 7 comprises Fresnel lens 14, pyroelectric sensor 15, signal processing circuit 16 and output switch 17.Described Fresnel lens 14 focuses on human infrared radiation on the described pyroelectric sensor 15; Described signal processing circuit 16 with described pyroelectric sensor 15 output signals amplify, Shelving, the break-make of the described output switch 17 of output SC sigmal control.
Described control circuit is used to control the proper functioning of said energy-conservation wall fan; Comprise and described human inductor 7 parallel first resistance 12 that are connected; One end of described first resistance 12 is connected with safety fuse cutout 13 with first port of controllable silicon 8; The other end is connected with second resistance 11, and the other end of described second resistance 11 connects charging capacitor 10 and bidirectional trigger diode 9, and the other end of described bidirectional trigger diode 9 connects the control utmost point of said controllable silicon 8; The other end of described charging capacitor 10 is connected with second port of said controllable silicon 8 and the live wire of input power supply; Described safety fuse cutout 13 connects with the common port of described speed governing pull switch 5, and the output terminal of described speed governing pull switch 5 is connected with described motor 2, and the other end of described motor 2 connects the zero line of described input power supply.
