Description

Gas burner movement and injection automatic ignition device

The utility model is a kind of gas cooker movement and injection automatic ignition device.

Existing gas cooker mainly relies on match combustion, also has by burning torch and ignites, and these people after for tense working are very bothersome, trouble again, because turn on the gas-fire cooking stove and igniting need two hands to finish, not doing a good job also pollutes the environment.

The utility model provides a kind of and can finish two kinds of actions simultaneously at above-mentioned deficiency, and the gas cooker movement and the induction apparatus that turn on the gas-fire cooking stove and ignite make existing gas cooker further perfect.

Technical solution of the present utility model is, adopt threeway, burner, the combining structure of injection automatic ignition device, induction apparatus has three parts, it is electronic switch, injector and igniter, electronic switch is by knob 11, pusher dog 12, impact collision block 13, spring 14, piezoelectric ceramics 10, switch lever 9 constitutes, injector is by tracheae 22, induction tunnel 15, injection tube 20 constitutes, igniter is made of spray point 18 and discharge electrode 19, discharge electrode 19 is contained in injection tube 20 front ends, electronic switch is connected with spray point 18 by high-voltage conducting wires 16, it is characterized in that, the rotary valve that is contained in control wireway 4 break-makes on the wireway 4 between threeway 1 and the burner 6 is connected with electronic switch by guide finger 8, by valve 5 and injector socket, rotary valve is by spring 2, nut 3, sealing bolt 28, cock 29, control valve constitutes, sealing bolt 28 is in cock 29 ends, nut 3 and spring 2 are housed, cock 29 tops are air chambers 30, air chamber 30 communicates with faucet hole 7, cock 29 bottoms are passage 26 and open slot 27, for switch lever 9 and guide finger 8 motions, cock 29 middle parts are gas channels 24, the valve 5 of cock 29 sides communicates with gas channel 24, control valve is contained in the cock 29, on the gas channel 24 in the middle, the break-make of control air chamber 30 and gas channel 24, control valve is by valve rod 25, sealing ring 23,31, spring 33, back-up ring 32,34 constitute, be contained in the sealing ring 31 of valve rod 25 lower ends, spring 33, back-up ring 2,34 stay in the passage 26, the end that induction tunnel 15 has nozzle 21 is enclosed within the injection tube 20, and injection tube 20 is fixed together by connecting part 17 spray points 18.Its operation principle is, knob 11 when the pressing electronic switch, the afterbody that the switch lever 9 that links to each other with knob 11 will act on the valve rod 25 in the passage 26 moves in air chamber 30, air chamber 30 is communicated with gas channel 24, when the knob 11 of electronic switch rotates a certain angle (as 30 °), rotary valve by guide finger 8-5 switch lever interlock also correspondingly rotates a certain angle, thereby the faucet hole in the cock 29 7 is connected with wireway 4, gas flows to burner 6 through the wireway of connecting 4, meanwhile also passes through faucet hole 7, air chamber 30, gas channel 24, valve 5 enters injector.When the knob 11 of electronic switch continues to be threaded to certain angle (as 60 °), pusher dog 12 on the switch lever 9 starts impact collision block 13, because the tension force of spring 14, make and impact collision block 13 and piezoelectric ceramics 10 interactions, this moment, the instantaneous voltage of piezoelectric ceramics 10 reached 15 kilovolts, through high-voltage conducting wires 16, send a telegraph 18 pairs on pin and be contained in discharge electrode 19 discharge electrodes 19 discharge of injection tube 20 ends, at this moment, the spark of discharge is just in time lighted the gas that overflows from injection tube 20, to burner 6 jet flames, lights gas cooker, when not pressing knob 11, the active force of 9 pairs of valve rods 25 of switch lever disappears, and valve rod 25 restores to the original state under the effect of spring 33, and air chamber 30 is disconnected with gas channel 24, the gas circuit of injector is closed, and the knob 11 of rotating electron switch has only the effect of regulating flame size again.

Advantage of the present utility model is, can be in the cooking stove that turns on the gas-fire, automatically and safely it is lighted, it is rational in infrastructure, make simple, be easy to installation, maintenance, be convenient to existing gas cooker is reequiped, and cost is low, be suitable for popularization, be suitable for the cooking stove of multiple fuel gas, non-standard low thermal mass burning gases.
