Description
The utility model relates to a kind of gas furnace, particularly a kind of button gas furnace.
The thermocouple flame-out protection device that general stove and accessory is adopted comprises thermocouple and magnetic valve two large divisions, so claim the magnetic control safety line again.Its electricity consumption sheet idol is made temperature-sensitive element.In the time of in thermocouple is in the flame scope, thermocouple is heated, and the free electron in the metal is accepted heat energy, and motion aggravates and formation heat difference electromotive force, insert the coil of magnetic valve when the electromotive force that thermocouple is produced, produce magnetic field and make the magnetic valve action, air valve is opened, the combustion gas conducting in the main airway, keep the main burner normal combustion, in case during the fray-out of flame that thermocouple detects, the electromotive force that thermocouple is drawn line end drops to zero, the electromagnetic valve coil dead electricity very soon.Under the effect of spring, it resets rapidly, and valve envelope position source of the gas passage is ended air feed, and main burner is flame-out.
Key pulse gas furnace in the market, its use are after connecting fuel gas source, push button earlier, and the pulse sparking continued to press about 10 seconds, allowed thermocouple be heated, and made the magnetic valve adhesive by thermocouple control, and furnace combustor could normal combustion.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of pushing button to loose one's grip, and need not push the button gas furnace of a period of time.
The purpose of this utility model can reach by following measure: the utility model comprises magnetic valve, thermocouple, nozzle, burner, button, push rod, intensity of a fire adjusting rod, the igniting pin, battery, pulse oscillation circuit, output circuit boosts, housing, it is characterized in that: also have microswitch, delay amplification circuit, battery is connected with pulse oscillation circuit and delay amplification circuit by microswitch, delay amplification circuit is connected with magnetic valve, microswitch joins by the positive pole of capacitor C 3 in diode D1 and the delay amplification circuit, the positive pole of C3 also joins by resistance R 4 and the base stage of triode T2, the colelctor electrode of T2 joins by resistance R 2 and the base stage of triode T1, the emitter-base bandgap grading of T1 joins by the positive pole of capacitor C 2 with capacitor C 3, the colelctor electrode of T1 and magnetic valve, thermocouple joins, and microswitch also joins by transformer B1 in diode D4 and the pulse oscillation circuit.
The purpose of this utility model can also reach by following measure: microswitch is contained in the place near button, when button is pressed, by depression bar pressing microswitch.
Fig. 1 is a functional-block diagram of the present utility model;
Fig. 2 is the utility model structural principle schematic diagram;
Fig. 3 is an electrical schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model is made up of magnetic valve 1, thermocouple 2, nozzle 3, burner 4, button 5, push rod 6, intensity of a fire adjusting rod 7, microswitch 8, igniting pin 9, battery 10, pulse oscillation circuit 11, the output circuit 12 that boosts, delay amplification circuit 13, housing 15 etc.4 etc. mounting structure of magnetic valve 1, thermocouple 2, nozzle 3, burning is identical with existing button stove and accessory, because this stove and accessory has the twin furnace head, so have two to overlap microswitches 8, button 5 etc.; And microswitch 8 is contained in the place near button 5, when button 5 is pressed, can push down microswitch 8 by depression bar 16, makes its closure, connects circuit power; Otherwise microswitch 8 disconnects, and cuts off the electricity supply.
With reference to Fig. 3, pulse oscillation circuit 11 comprises triode T5, transformer B1, diode D4, capacitor C 6, resistance R 9 etc.; The output circuit 12 that boosts comprises controllable silicon SCR, bilateral diode D6, diode D5, resistance R 10, R11, capacitor C 8, C10, transformer B3 etc.; Delay amplification circuit 13 comprises triode T1, T2, capacitor C 2, C3, resistance R 1～R4, diode D1 etc.Because of this stove and accessory has the twin furnace head, so the delay amplification circuit of triode T3, T4, capacitor C 4, another burners of composition such as C5, diode D2; And transformer B2, capacitor C 7, C9 etc. also with delay amplification circuit 13 in the positive pole of capacitor C 3 join, the positive pole of C3 also joins by resistance R 4 and the base stage of triode T2, the colelctor electrode of T2 joins by resistance R 2 and the base stage of triode T1, the emitter-base bandgap grading of T1 joins by the positive pole of capacitor C 2 with capacitor C 3, the colelctor electrode of T1 and magnetic valve 1, thermocouple 2 joins, and microswitch 8 also joins by transformer B1 in diode D4 and the pulse oscillation circuit 11.Now only narrate the operation principle (principle of another burner is identical) of one of them burner.
After microswitch 8 is depressed, connect power supply, triode T5 action produces vibration, and through transformer B1(or B2) boost, by igniting pin 9 pulses sparking, simultaneously to C3(or C5) charge; This moment, stove and accessory promptly can be struck sparks in pulse, lighted furnace combustor.When openhanded the opening that push button, microswitch 8 promptly disconnects, this moment capacitor C 3(or C5) promptly to T2(or T4), T1(or T3) discharge, keep magnetic valve 1 adhesive, make the burner can normal combustion; Until C3(or C5) discharge off, simultaneously the thermocouple generation electric current that is heated in the flame combustion process is kept the magnetic valve adhesive, guarantees that furnace combustor in use can continue normal combustion.When not using stove and accessory, as long as button is restored, then microswitch disconnects, and under mechanism, all recover reset condition.
The utility model has following advantage compared to existing technology:
1. one push button and to loose one's grip, need not press a period of time; And easy to operate, one by i.e. igniting, again by stopping working, automatically plays unexpected blowout protection effect.
2. simple in structure, circuit is reasonable, and cost is lower, and is safe and reliable, is a kind of novel gas furnace.
