Abstract
An alarming device capable of automatically closing a gas source after extinguishment of a gas stove comprises a power source, a switch, a diode, a triode, an integrated block, a loudspeaker, a resistor, a photoresistor and an electromagnetic valve. An anode of the power source is connected with a power end of the integrated block, one end of the electromagnetic valve and one end of the resistor; an output end of the integrated block is connected with the loudspeaker, a ground wire end of the integrated block is connected with a collector electrode of the triode and the other end of the electromagnetic valve, a base electrode of the triode is connected with the other end of the resistor and one end of the photoresistor, and the other end of the photoresistor and an emitting electrode of the triode are connected together with a cathode of the power source; and two ends of the electromagnetic valve are connected with the diode in parallel. The alarming device has simple circuits, is safe and reliable, is mounted on a gas delivery pipe of the stove in an assorted manner, can automatically close the gas source and give an alarm under the condition of extinguishment of the stove, and accordingly avoids accidents of fire hazards and poisoning.
Description
Technical field
The utility model relates to a kind of warning device, is specifically related to a kind of gas range and extinguishes the warning device that can close source of the gas automatically.
Background technique
Present gas-fired boiler does not all extinguish the controlling alarm measure, when using gas cooker or gas water-heating furnace, the situation that stove and accessory extinguishes often occurs, as be not easy to cause the generation of poisoning and fire accident by timely discovery.
The model utility content
The purpose of the utility model is exactly the defective that exists to existing technology, provides a kind of gas range to extinguish the warning device that can close source of the gas automatically.
Its technological scheme is: comprise power supply, switch, diode, triode, integrated package, loudspeaker, resistance, photoresistor and solenoid valve.The positive pole of said power supply is connected with an end of the power end of integrated package, solenoid valve and an end of resistance; The output terminal of integrated package connects loudspeaker; The ground terminal of integrated package is connected with the other end of the collector electrode of triode and solenoid valve; The base stage of triode is connected with an end of the other end of resistance and photoresistor, and the negative pole of the other end of photoresistor, the emitter of triode and power supply connects; The said solenoid valve two ends diode that is connected in parallel.
Wherein, said power supply is dryelement cell or ACDC stabilized power supply.Said integrated package is alert sound or music integrated circuit.
It is simple, safe and reliable to the utlity model has circuit, on the supporting gas pipeline that is installed in stove and accessory, can close source of the gas automatically and send warning in the flame-out situation of stove and accessory, avoids fire, intoxication accident to take place.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model circuit theory diagrams.
Embodiment
With reference to Fig. 1; A kind of gas range extinguishes the warning device that can close source of the gas automatically; Comprise power supply DY, K switch, diode D, triode T, ic chip, loudspeaker L, resistance R, photoresistor RL and solenoid valve J, the positive pole of said power supply DY is connected with the end of the power end of ic chip, solenoid valve J and an end of resistance R; The output terminal of ic chip connects loudspeaker L; The ground terminal of ic chip is connected with the collector electrode of triode T and the other end of solenoid valve J; The base stage of triode T is connected with the end of the other end of resistance R and photoresistor RL, and the emitter of the other end of photoresistor RL, triode T and the negative pole of power supply DY connect; The said solenoid valve J two ends diode D that is connected in parallel.
Wherein, said power supply DY is dryelement cell or AC/DC stabilized power supply.Said ic chip is alert sound or music integrated circuit.
Make when using the utility model, solenoid valve is installed on the gas source pipe, photoresistor is installed near the stove and accessory flame.When gas-fired boiler was worked, first powered-down K switch was lighted stove and accessory work, turns on the power switch K after the stove and accessory normal combustion, and at this moment, photoresistor RL presents Low ESR, and triode T ends, not adhesive of solenoid valve J, and its road is unimpeded, the stove and accessory proper functioning; When stove and accessory was stopped working, photoresistor RL presented HR high resistance, triode T conducting; Solenoid valve J adhesive, gas circuit is closed, and stove and accessory quits work; Simultaneously form warning circuit and send warning, thereby avoid fire, intoxication accident to take place by ic chip and loudspeaker L.
