Abstract

The utility model relates to a sub-ultrasonic remote-control switch for regulating voltage, which belongs to the field of wireless remote control, particularly relating to a device using sub-ultrasonic to remotely control switches of electric appliances. After a receiver receives sub-ultrasonic frequency signals which are generated by a transmitter, the sub-ultrasonic frequency signals are converted into electric signals with a definite frequency by a piezo-electric acoustic frequency sensor; the frequency of the electric signals which are amplified by a frequency selection amplification circuit selected; the amplified signals triggers a phase regulating integrated circuit; the output of the utility model controls a bidirectional controlled silicon to output voltage with different amplitudes; the defects that the existing sub-ultrasonic remote-control switch can not adjust voltages and can not output voltage are solved; the utility model is mainly used for the remote control of household appliances.

Description

Sub-ultrasonic remote-control switch for regulating voltage

The utility model belongs to the wireless remote control field, particularly relates to a kind of switching device of remote control electrical appliance power supply.

Existing sub-ultrasonic remote-control switch, easy to use, simple, it is the Push And Release that comes the remote control electrical appliance power supply with inferior ultrasonic, has brought many conveniences to people's life.But existing this switch does not possess the pressure regulation output function, such as unsatisfactory to aspects such as lamp light modulation, electric fan pressure regulation.

The purpose of this utility model is to provide a kind of sub-ultrasonic remote-control switch that can pressure regulation output.

Its technical scheme is: its reflector is made up of air bag and siren, receiver is made up of shell, plug, jack and receiving circuit, the working power circuit of forming by devices such as step-down current limliting, rectifying and wave-filtering, voltage stabilizings in the receiving circuit, for the signal receiving circuit of being made up of acoustic frequency sensor and frequency-selective network provides direct-current working volts, the signal that receives adds to the trigger end of phase modulation ic chip after amplifying circuit amplifies, the output end signal control bidirectional triode thyristor BCR of IC exports different voltages.

Because receiving circuit has adopted the phase modulation ic chip, voltage divides third gear output, can regulate easily as incandescent lamp light intensity, fan speed etc.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the structural representation of reflector;

Fig. 2 is the profile Facad structure schematic diagram of embodiment 1 and receiver;

Fig. 3 is the profile side structure schematic diagram of embodiment 1 receiver;

Fig. 4 is the receiving circuit schematic diagram of receiver;

Fig. 5 is the contour structures schematic diagram of embodiment 2.

Embodiment 1: as shown in Figure 1, reflector is made up of air bag 1 and siren 2, and when hand pinching rubber pneumatic bag, the air communication of certain pressure is crossed the air bag oral area and entered the flute body, the acceleration shock siren edge of a knife produces cavity resonance again, launches the inferior ultrasonic wave of 16～20KHZ from the wedge shape mouth.

As shown in Figure 4, the civil power of A, B termination 220V, 50HZ is through C ₁Step-down, R ₁Current limliting, D ₁, D ₂Rectification, C ₂Filtering, voltage-stabiliser tube DW voltage stabilizing are for by piezoelectricity acoustic frequency sensor JS, triode BG ₁, resistance R ₂, frequency-selective network LC ₃The signal receiving circuit of forming provides direct-current working volts, and the signal of telecommunication of certain frequency is through BG after the frequency-selecting ₂, BG ₃Amplify, the signal after the amplification is through C ₆, R ₆Deliver to the trigger end pin 1 of phase modulation integrated package HT7713, control the angle of flow of bidirectional triode thyristor BCR by the output signal of output pin 3.Touch wire terminals M and also can trigger HT7713, and control bidirectional triode thyristor BCR.The angle of flow difference of bidirectional triode thyristor, just different from the voltage of C, the output of D two ends, realized the purpose that pressure regulation is exported.

During use, receptor plugs 4 is inserted in the supply socket, needs the appliances power source plug of control to be inserted in the jack 5 of receiver, the pinching reflector just can be realized the remote control to the switch of electrical equipment.

Embodiment 2: as shown in Figure 5, receiver has a screw cap 6(to be equivalent to the plug 4 of embodiment 1), be used for being connected with conversion lamp holder.7 for installing the parts of incandescent lamp, and 3 is the receiver shell, and reflector and receiving circuit are identical with embodiment 1.This embodiment is mainly used in the light modulation of incandescent lamp.
