Be illustrated in conjunction with the accompanying drawings according to embodiment below.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
Fig. 3 is air feed figure of the present utility model.
Embodiment 1: as Fig. 1, Fig. 2, shown in Figure 3, connect A, B 2 points among Fig. 2, electromagnetic gas valve 19 is installed on the air inlet pipe 1, the escape pipe 16 of electromagnetic gas valve 19 links to each other with piezoelectric ceramic ignitor 15, link rod 17 links to each other with piezoelectric ceramic ignitor 15, around the combustion head 3 thermocouple 4 is installed, an end of thermocouple 4 links to each other with electromagnetic gas valve 19, and the other end of the other end of thermocouple 4 and electromagnetic gas valve 19 is by the contact S on the timer 12
1Link to each other.Thermocouple 4 is apart from main combustion head 3 millimeter of combustion head 3.During use, the knob 14 of pressing piezoelectric ceramic ignitor 15 burnt the main combustion head of combustion head 3 about 20 seconds, made thermocouple 4 be heated to normal power supply and made electromagnetic gas valve 19 adhesives, at this moment, unclamp the knob 14 of piezoelectric ceramic ignitor 15, the main combustion head normal combustion of combustion head 3.Arrived the set time, the contact S of timer 12
1Disconnect, electromagnetic gas valve 19 dead electricity, the cut-out source of the gas that resets of the valve body in the electromagnetic gas valve 19 makes the main combustion head burn-out of combustion head 3.Piezoelectric ceramic ignitor 15 also can use ignition.
Embodiment 2: use for convenience, increasing following structure on the basis of embodiment 1: bimetal leaf 21 is installed before ignition burner 6, bimetal leaf 21 links to each other with an end of fork 7, the other end of fork 7 is equipped with magnet 9, magnet 9 is installed between the tongue tube 8,10, the contact S of an end of battery 2 and electromagnetic gas valve 19 and tongue tube 8
2Series connection, the other end is connected with an end of thermocouple 4, the contact S of the other end of thermocouple 4 and tongue tube 10
3Series connection, contact S
1Can with the contact S of tongue tube 8,10
2, S
3Series connection.During use, the combustion gas of access at first enters electromagnetic gas valve 19, is entering the main combustion head of combustion head 3.During burning, the thermocouple 4 generation electromotive force that is heated.Bimetal leaf 21 temperature distortions are rotated fork 7, and magnet 9 is at the contact of tongue tube 8 S
2Move the top, contact S
2Adhesive continues current collector S
2, S
3Simultaneously adhesive, current collector S again
2Disconnect contact S
3The action of adhesive.During use, connect source of the gas, the knob 13 of rotary timer 12, contact S
1Connect, be set required burning time.Press piezoelectric ceramic ignitor 15 link rod 17 is rotated, promote electromagnetic gas valve 19, make it ventilation.The knob 14 of rotary piezoelectric ceramic igniter 15 makes ignition burner 6 burnings, directly adds thrermostatic bimetal-plate 21, bimetal leaf 21 distortion back rotational swing rods 7, and the magnet 9 on the fork 7 makes the contact S of tongue tube 8
2Connect, disconnect the contact S of tongue tube 10
