The utility model relates to an electric appliance remote controller, comprising a keyboard system, a coding system, an executive system, an amplification circuit and an emission load part, wherein, a boosted circuit is connected between the executive system and the emission load part, and the boosted circuit is formed by the orderly connection of an inverter, an oscillator, a voltage hoisting circuit and a full filter circuit. The utility model has the advantages of low requirement of battery voltage, high emission efficiency, high transmission power, economy, etc.
Description
The utility model relates to a kind of electric appliance remote controller.
The reflector of the radio remote controlled switch of using comprises keyboard system coded system, executive system, amplifying circuit, emission load at present, for making reflector reach certain transmitting power, must use about 12 volts battery, if use the 1.5V battery, then need 8 batteries like this, volume is big and heavy, if directly use 12V type battery, because the performance of such battery, concerning the user, the battery usage charges are higher, and the battery value is low.Therefore, how under the prerequisite that keeps the reflector transmitting power, the voltage request that reduces battery then becomes the improved requirement of this reflector.The reflector of the radio remote controlled switch of selling is considered from factors such as volume, weight and battery its usage economies at present, No. 5 batteries of one a well matched 3-4 1.5V, the result who causes like this is that transmitting power, the emission effciency of such reflector is lower, transmitting range is shorter, influences the normal use of this reflector.
The purpose of this utility model just is to overcome above-mentioned weak point of the prior art, provides that a kind of cell voltage requirement is low, emission effciency, transmitting power height, uses economic remote control switch reflector.
The purpose of this utility model reaches by following measure: a kind of remote control switch reflector, comprise keyboard system, coded system, executive system, amplifying circuit, emission load, said executive system also connects a booster circuit with emission between the load, and said booster circuit is connected by an inverter, an oscillator, a voltage lifting circuit and a whole filter circuit successively and forms.
Below in conjunction with accompanying drawing the utility model embodiment is elaborated.
Fig. 1 is the utility model embodiment circuit diagram.
The utility model remote control switch reflector, comprise keyboard system 1, coded system 2, executive system 3, amplifying circuit 4, emission load 5, executive system also connects a booster circuit with emission between the load, and booster circuit is connected by an inverter 6, an oscillator 7, a voltage lifting circuit 8 and a whole filter circuit 9 successively and forms.Inverter is a NAND gate; Oscillator is a RC oscillator, comprise NAND gate 10,11, resistance R 1, R2, R3, capacitor C 1, two inputs of NAND gate 10 outputs and NAND gate 11 are linked together, divide two-way behind the connecting resistance R2, one tunnel input through resistance R 1 and NAND gate 10 connects, another road connects through the output of capacitor C 1 and NAND gate 11, and another input of NAND gate 10 connects with the output of inverter 6, connects with the input of voltage lifting circuit behind the output connecting resistance R3 of NAND gate 11; Voltage lifting circuit comprises an inductor L1 and a transistor 12, transistor is a NPN transistor, base stage is the input of said voltage lifting circuit, the output of the very said voltage lifting circuit of current collection also connects with whole filter circuit, and transistorized collector electrode connects with battery through inductor L1 simultaneously; Whole filter circuit comprises diode VD, electrochemical capacitor C2, inductor L2, the input of the just very whole filter circuit of diode, negative pole connects with electrochemical capacitor C2 positive pole, inductor L2 respectively, the negative pole of capacitor C 2 connects back ground connection with transistorized emitter, the other end of inductor L2 connects with said emission load.Three NAND gate are to utilize existing three gate circuits in 4011 integrated packages in the foregoing description, and inverter 6 also can directly use a not gate certainly, and NAND gate 11 also can be used a not gate instead and be replaced.
Operation principle is as follows: when in running order, executive system is to inverter output one " 0 " electric potential signal, oscillator 7 work, the oscillating impulse of formation puts on the base stage of transistor 12, makes transistor intermittently open-minded, under the effect of inductor L1, transistorized collector electrode forms the very high voltage wave of peak value, and through whole filter circuit, amplified DC voltage promptly acts in the emission load, experiment shows that it is 9-16V that battery adopts 4.5 volts of voltages can cause the voltage in the emission load; When reflector was in non operating state, executive system was sent " 1 " electric potential signal, oscillator place dead-beat state, and transistor 12 ends, the battery no-output.
Compared with prior art, it is low to the utlity model has the cell voltage requirement, Emission effciency, transmitting power height and use economic dispatch advantage.
