Beneficial effect: the utility model sub-ultrasonic remote-control socket, performance is safe and reliable, it is little to take up space, and can be inserted in conveniently on the former commercial power socket in family or office and use; Be inserted on this sub-ultrasonic remote-control socket as desk lamp, electric fan, pinching air bag by hand can be at the Kai Heguan of 15 meters these class small household appliances of scope inner control, reach not only simple economy, but also convenient and practical purpose.

Description of drawings

Accompanying drawing 1 is the sub-ultrasonic remote-control socket circuit catenation principle figure that the utility model provides.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, a kind of sub-ultrasonic remote-control socket is made up of DC power-supply circuit, triggering signal generation circuit, bistable circuit and control switch; The AC220V civil power is connected with pin 1 end, pin 3 ends of bridge rectifier (D1-D4) respectively after resistor R 1, capacitor C1 step-down; Behind bridge rectifier (D1-D4) from

2 and 4 output dc voltages of pin, the direct voltage stably of acquisition+8V after capacitor C2, resistor R 2, capacitor C3 filtering; Triode VT1 and triode VT2 form triggering signal and produce circuit, resistor R 3 is the biasing resistor of VT1, ZD is inferior ultrasonic receiver, inductor L1 and capacitor C4 form antiresonant circuit, resonance frequency is 18KHz, when hand-held air bag sends the inferior ultrasonic wave of 18KHz, ZD converts the ultrasonic signal that receives to the corresponding signal of telecommunication, amplify through triode VT1, choose the signal of 18KHz by the shunt-resonant circuit of triode VT1 collector electrode, delivering to triode VT2 by capacitor C5 amplifies and shaping, form with the spike signal of telecommunication, again through resistor R 5, capacitor C6 output, generation can be controlled the triggering signal of bistable circuit.Triode VT3, triode VT4, resistor R 7, R8, R9, R10, R11, diode D6, D7, capacitor C7, C8 constitute bistable circuit, this circuit has symmetry, because the performance parameter of triode VT3, triode VT4 can not be fully definitely identical, when spike is imported, at first conducting of triode VT4, when the about 0.3V of collector electrode of triode VT4, impel triode VT3 to end, this is a kind of stable state; When two spike when input arranged, triode VT4 is become by conducting and ends, and triode is by by becoming conducting, and this is another kind of stable state; When triode VT4 conducting, its collector voltage is about 0.3V, make triode VT5 be in cut-off state by resistor R 12, LED is not luminous, the coil J no power of relay, the switch J-K of relay control is in open-circuit condition, and promptly the socket P that controls on the sub-ultrasonic remote-control socket is in power failure state, and the electric equipment that is inserted on the socket P can not be worked; When 15 meters with interior scope in hand pinch can produce inferior ultrasonic wave air bag the time, inferior ultrasonic receiver ZD receives ultrasonic signal and converts the corresponding signal of telecommunication to, amplify through triode VT1, choose the signal of 18KHz by the shunt-resonant circuit of triode VT1 collector electrode, delivering to triode VT2 by capacitor C5 amplifies and shaping, form through resistor R 5 with spike, capacitor C6 output, triode VT4 ends, its collector voltage is about 8V, make triode VT5 saturation conduction by resistor R 12, LED is luminous, the coil J energising of relay, the switch J-K of relay control is in closure state, promptly the socket P that controls on the sub-ultrasonic remote-control socket be in electricity condition, the electric equipment that is inserted on the socket P can be worked.

In the accompanying drawing 1, triode VT1, VT3, VT4, VT5 select the C9014 model for use, and VT2 is the C9015 model; Resistor R 1-R12 selects the 1/4W carbon film resistor for use, R1:680K wherein, R2, R4:1K, R3:270K, R5:220 Ω, R6, R11, R12:2.2K, R7-R10:10K; Capacitor C1 selects for use withstand voltage for the 400V capacity is the 0.47uF model, and capacitor C2 and C3 select for use: the electrolytic capacitor of 47uF/25V; Diode D1-D7 selects the IN4007 model for use.

Though described execution mode of the present utility model in conjunction with the accompanying drawings, the protection range that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
