Abstract
The utility model relates to a miniature remote switch which is composed of a miniature transmitter and a socket type receiver. The utility model is characterized in that the transmitter transmits electromagnetic wave outward by a high-frequency oscillator through a miniature ring coil; the receiver is composed of an ultrasound regenerating wave detector, an amplification circuit, an electronic switching circuit and a power supply circuit. The remote switch has small volume, and can be put into a pen or hung on a key chain; the miniature remote switch is conveniently used; the distance of remote control is 10 meters, and the miniature remote switch can be used widely for electric lamps, electric fans, air conditioners and other electric appliances.
Description
This invention is a kind of miniature remote controlled switch that is used for far distance controlled electrical equipment.
At present, many electrical equipment do not have distant control function.Have a kind of extruding gasbag that utilizes to send the product that the certain frequency sound wave comes gauge tap on the market, but this telepilot volume is big, carries inconvenience, and because the interference of ambient sound cause the misoperation of switch easily.
The purpose of this invention is to provide that a kind of volume is little, the miniature remote controlled switch of the radio of reliable in action.
It is made up of a transmitter and a receiver.General transmitter circuit is made up of a LF oscillator and a high frequency oscillator, in order to reduce the volume of transmitter, transmitter provided by the invention is a single high frequency oscillator, and it is by the electromagnetic wave of a micro loop single-turn circular coil to the external radiation characteristic frequency.Toroid winding is the part of oscillatory circuit, again as emitting antenna.Receiver is made up of superregenerative detector, amplifying circuit, electronic switch and feed circuit.Superregenerative detector comes down to a kind of batch (-type) oscillator, its oscillation frequency is consistent with the transmitter oscillation frequency, because the interference and the electronics thermal agitation of environment spurious signal, superregenerative detector will produce a kind of distinctive noise, amplify back control electronic switch through amplifying circuit and disconnect electric switch, will be suppressed in case receive the high-frequency electromagnetic signal that transmitter sends, electronic switch is just connected electric switch.For easy to use, launcher shell is made pen type or is hung on the key chain.
Below in conjunction with accompanying drawing the present invention is done further narration.
Fig. 1 is a transmitter circuit.
Fig. 2 is an acceptor circuit, 1-superregenerative detector wherein, 2-amplifying circuit, 3-electronic switch road, 4-feed circuit.
Fig. 3 is transmitter pen type shell section figure, 1-end cap wherein, and the 2-battery, 3-1 microswitch 1,3-2 microswitch 2,5-shell, 6-writes structure.
In Fig. 1, work as switch S
1Closed looping coil L
1, work as switch S
2Looping circle L when closed
2, because L
1With L
2Have different sectional areas, therefore, high frequency oscillator can be launched two kinds of different frequencies, thus remote-controlled two cover electric switches.Transmitter also can be provided with several switch S more, thus remote-controlled many cover electric switches.Certainly, also can be by changing the frequency that electric capacity changes transmitter.
In Fig. 2, can adjust the oscillation frequency of superregenerative detector by adjusting capacitor C, herein no longer narration.
In Fig. 3, the quantity of microswitch 3 is corresponding to the quantity of transmitter switch S.Writing structure 6 is that a kind of the utilization rotated the known technology that makes refill for ball-point pen flexible, also no longer stating more.
Claims (3)
1, the present invention relates to the miniature remote controlled switch of a kind of radio, it is made up of transmitter and receiver, it is characterized in that transmitter passes through a small outside radiated electromagnetic wave of toroid winding by a high frequency oscillator, receiver is made up of super-regenerative receiver, amplifying circuit, electronic switching circuit and feed circuit.
2, miniature remote controlled switch according to claim 1 is characterized in that the toroid winding of said transmitter only is made up of single turn.
3, miniature remote controlled switch according to claim 1, the transmitter that it is characterized in that it has the different toroid winding of plural sectional area, connect by separately switch and circuit, thereby make transmitter can produce the electromagnetic wave of two or more frequencies, can control a plurality of electric switches simultaneously.
