The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, show operation principle of the present utility model, mainly comprised detection module 2, control module 1 and executive module, and be connected to form the automatic control system device by lead and connector between detection module 2, control module 1 and the executive module.Control module 1 is installed in the cooking stove for overall package forms, executive module mainly is made up of high-voltage pulse ignition coil, igniting pin 4 and magnetic valve 3, and described magnetic valve 3 is connected with by-passing valve 7, control valve 8 and intake valve 9 respectively, and by-passing valve 7 also is connected with a gas furnace 5 with an end of intake valve 9; The top of described control module 1 also is provided with an air blast 6, detection module 2 is installed in the external side of the inner burner hearth of cooking stove, the pressure detecting bar at its top places the Lu Quan edge, and the top of pressure detecting bar protrudes from stove circle 10-15mm, working power employing 220V AC power.

When using cooking stove, when pot is placed on the cooking stove stove circle, pressure detecting bar upper end in the detection module contacts with the portion in the bottom of a pan, because pot body deadweight gravity is depressed the pressure detecting bar, travel switch when pressure detecting bar lower ends downward is slided about 5-8mm in the shake-up pressure sensitive device, the ignition switch of travel switch and gas supply electromagnetic valve power switch are opened simultaneously, igniting and air feed signal are delivered to control module rapidly, control module will be lighted a fire and the air feed power delivery is given high-voltage pulse igniter igniting (igniter cuts out after second automatically by time relay control ignition operation time 5-10), gas supply electromagnetic valve is opened simultaneously, combustion gas enters the cooking stove burner, cooking stove burning work this moment, whole ignition process finishes.When pot leaves the cooking stove mouth (as reinforced, sabot, wash pot etc.); because the pressure detecting bar loses the gravitational pressure of pot; back-moving spring in the detection module goes back to the pressure detecting masthead to original original state position; at this moment the wiper block of pressure detecting bar lower end leaves the touch point of travel switch; relay contact will delay time (0-5 can regulate second) cut off the gas electromagnetic valve power supply; closed electromagnetic valve also stops the burner of cooking stove is supplied fuel, and cooking stove is ceased fire automatically.Repeat above process and realize that pot puts stove automatic ignition work on the stove, pot leaves the flame-out intelligence that quits work of the cooking stove automatic time delay spark delay function of stopping working automatically.

As shown in Figure 2, showed the utility model control module inner member installation diagram, be provided with a plurality of travel switches, travel switch 1 connects detection module, travel switch 2 connects AC220V input power supply, travel switch 3 connects the 2A fuse, and travel switch 4 connects the magnetic valve of executive module, and the bottom of this module is provided with contact fire pin 5.Described KT1 and KT2 are the time relay, and H1 is a power supply indicator, and H2 is the magnetic valve relay indicating light, and H3 is the high-voltage pulse ignition light, and DH is the high-voltage pulse igniter; When native system is installed on power supply state (start), power supply indicator H2 lights the expression power connection, and time relay KT1 energising is through disconnecting the KT1 normally-closed contact after the original state, and magnetic valve is a closed condition, and whole apparatus system is in holding state.When travel switch XK is depressed when placing on the test rod (pot) switch often open with normally-closed contact closed simultaneously with separate, this moment, the power supply of KT1 was disconnected, its normally-closed contact instantaneous recovery closure state send to magnetic valve, magnetic valve is opened to burner and is supplied gas, this moment is because the normally opened contact closure of travel switch, therefore power supply will be delivered to KT2 and high-voltage pulse igniter DH, the igniting pin of igniter DH begins igniting, at this moment stove automatic ignition work, igniter after igniting is finished (5-10 adjusts arbitrarily in second according to actual needs) stop igniting automatically.

When travel switch returns to the normal position (pot leaves cooking stove), often open and the normally-closed contact of travel switch separate and closure simultaneously, this moment, KT1 got, its time-delay normally opened contact time-delay (being accustomed to adjusting 0-10 according to the operator delayed time in second) disconnects the magnetic valve outage closes, and the cooking stove auto extinguishing quits work.KT2 outage this moment, its normally-closed contact resets and gets back to initial holding state.

But present embodiment as long as regulate the impulse stroke of limit, the slide position regulated at will test rod of test rod lower end in the detection module, makes the duration of ignition more accurate according to the actual needs.Because test rod is in long-term contacting and friction with pot, so aim at replacing test rod and designed conveniently substitute mode of novelty in this example.The lower cover fixed screw that is about to detection module unloads, and pulls down the test rod lower end fixedly behind the set screw, slide block of slide block, test rod just can be from top convenient directly dismounting extract out and clean or replacing.
