Summary of the invention
The purpose of the utility model is in order to overcome deficiency of the prior art; A kind of intelligent stand fan that can regulate power automatically is provided; This scheme is to use human inductor to regulate the power output of control circuit, avoids working under the unmanned situation, thus energy saving.
The utility model solves the technological scheme that its technical problem adopted:
Can regulate the intelligent stand fan of power automatically, comprise base, support; Motor, fan blade, guard; And speed control switch and head-shaking switch; Carry out the control circuit of start-stop and speed governing, also comprise: be arranged on the human inductor on the described guard, described human inductor is connected with described control circuit.
Described speed control switch is set to the first power key, the second power key, the 3rd power key, the 4th power key and the 5th power key.
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 the common port of silicon controlled first port and described speed control switch; The other end is connected with second resistance; The other end of described second resistance connects charging capacitor and bidirectional trigger diode, and 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 power firestreak with said silicon controlled second port; The output terminal of described speed control switch is connected with described motor, and the other end of described motor connects described zero-power line.
The beneficial effect of the utility model mainly shows as in unmanned situation can reduce power output, energy-conserving and environment-protective automatically; Detect after the human body, increase power again, practical and convenient.
Description of drawings
Fig. 1 is the outline drawing of intelligent stand fan;
Fig. 2 is the control principle figure of intelligent stand 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 intelligent stand fan of power automatically, comprise base 1; Support 2, motor 3, fan blade 4; Guard 5, and speed control switch 6 and head-shaking switch 7, the control circuit that carries out start-stop and speed governing; Also comprise the human inductor 8 that is arranged on the described guard 5, described human inductor 8 is connected with described control circuit.
Wherein, described speed control switch 6 is set to the first power key, the second power key, the 3rd power key, the 4th power key and the 5th power key, corresponding different respectively rotation speeds of the fan.Voluntarily whether the described intelligent stand fan of described head-shaking switch 7 controls swing, the adjustment air supply direction.
Described human inductor 8 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 intelligent stand fan; Comprise and described human inductor 8 parallel first resistance 13 that are connected; The common port of one end of described first resistance 13 and first port of controllable silicon 9 and described speed control switch 6; The other end is connected with second resistance 12; The other end of described second resistance 12 connects charging capacitor 11 and bidirectional trigger diode 10, and the other end of described bidirectional trigger diode 10 connects the control utmost point of said controllable silicon 9, and the other end of described charging capacitor 11 is connected with power firestreak with second port of said controllable silicon 9; The output terminal of described speed control switch 6 is connected with described motor 3, and the other end of described motor 3 connects zero-power line.
When the user when using said intelligent stand fan; Described human inductor 8 detects the existence of human body, and described output switch 17 closures are with 13 short circuits of described first resistance; Therefore; The duration of charge of described charging capacitor 11 shortens, can be rapidly through the described controllable silicon 9 of described bidirectional trigger diode 10 conductings, and this moment, output power was in maximum rating; On the contrary; Described human inductor 8 can not detect the existence of human body, and described output switch 17 breaks off, and described first resistance 13 reduces charging current; Therefore; The duration of charge of described charging capacitor 11 increases, and the ON time of described controllable silicon 9 shortens, and this moment, output power was in minimum state.
In sum, the utility model provides a kind of intelligent stand fan that can regulate power automatically, increases the human detection function; In control circuit, use human inductor to regulate power output; After can realizing that the user leaves, reduce output power automatically, and after the user returns; Automatically recover high-power output, promptly reach energy conservation object.
