[0002] The existing gas stove mainly has two ignition modes of piezoelectric ignition and electronic pulse continuous ignition. The piezoelectric ignition, also known as electronic ignition, ignites by hammering piezoelectric ceramic to generate electric spark, and needs to be used with a fire spraying head and an ignition needle.

[0003] The electronic ignition device of the prior art sets the gas outlet of the nozzle and the ignition needle below the bottom of the burner head of the burner, and the burner head is provided with a fire gap, so that the nozzle sprays fire to the fire gap of the burner head to ignite the burner after piezoelectric ignition, thereby igniting the inner and outer ring flames of the burner.

[0004] In addition, some technologies use an ignition needle and a fire spraying gas pipe to extend from the inner cavity of the gas stove to above the burner head, and the fire spraying gas pipe and the ignition needle are arranged close to each other, and the fire spraying port faces the discharge end, thereby improving the success rate of ignition. However, in actual use, if it is used outdoors or at the air inlet, the fire from the fire spraying port will be blown to one side, thereby reducing the success rate of ignition. SUMMARY

[0005] The main purpose of the utility model is to provide an electronic ignition structure which improves the success rate of ignition by setting two fire spraying ports on the side of the top of the fire spraying gas pipe facing the ignition needle.

[0006] The utility model provides an electronic ignition structure, which comprises a base, an ignition needle and a fire spraying gas pipe.

[0008] The fire spraying gas pipe is provided with a fire spraying seat on one side facing the ignition needle. The front center line of the fire spraying seat is perpendicular to the vertical center line of the ignition needle. Two fire spraying ports are mirror-imaged arranged on the fire spraying seat along the front center line of the fire spraying seat. The two fire spraying ports can improve the success rate of ignition of the electronic ignition structure.

[0009] Preferably, the base is provided with a base connecting hole, and the inner side of the base connecting hole is provided with a base inner connecting thread. The side of the ignition needle is provided with an ignition needle outer side connecting thread. The base inner connecting thread and the ignition needle outer side connecting thread are matched, so that the ignition needle is screw-connected and arranged on the base.

[0010] Preferably, a rotating component is provided on the top of the outer connecting thread of the ignition needle on the outer side of the ignition needle, which is fixedly connected to the ignition needle, so that the ignition needle can be threadedly connected to the base by rotating the rotating component.

[0011] Preferably, the cross-section of the rotating component is hexagonal.

[0012] Preferably, an annular windproof protrusion is provided on the top side of the flamethrower pipe.

[0013] Preferably, the windproof protrusion has an air intake groove on the side facing the ignition needle, along the center line of the front of the flame base, which allows air to enter.

[0014] Preferably, the bottom of the ignition needle is connected to the discharge end via a wire, and the bottom of the flame jet pipe is connected to the gas conduit.

[0015] Preferably, at least one air inlet is provided at the bottom side of the flamethrower pipe.

[0016] The beneficial effects of the electronic ignition structure of this utility model are as follows:

[0017] 1. Setting two flame nozzles can improve the ignition success rate of the electronic ignition structure.

[0018] 2. By using a one-piece molded flamethrower pipe and base, the flamethrower pipe's exhaust direction is always directed towards the ignition needle, thus reducing the difficulty of installation and debugging, and improving product yield. Attached Figure Description

[0029] A base connecting hole 31 is arranged on the other side of the base 3, a base inner connecting thread 32 is arranged on the inner side of the base connecting hole 31, an ignition needle outer side connecting thread 22 is arranged on the side surface of the ignition needle 2, the base inner connecting thread 32 and the ignition needle outer side connecting thread 22 are matched, so that the ignition needle 2 is screw-connected to the base 3. A rotating piece 21 fixedly connected to the ignition needle is arranged on the top of the ignition needle outer side connecting thread 22 on the outer side of the ignition needle 2, the cross section of the rotating piece 21 is hexagonal, the ignition needle 2 is screw-connected to the base 3 by rotating the rotating piece 21. The bottom of the ignition needle 2 is connected to the discharge end through a wire 4.

[0030] The flame spraying gas pipe 1 is integrally formed on one side of the base 3, and the integrally formed flame spraying gas pipe 1 and the base 3 are arranged, so that the gas outlet direction of the flame spraying gas pipe 1 is always directed to the ignition needle 2.

[0031] A flame spraying seat 11 is arranged on the side of the flame spraying gas pipe 1 directed to the ignition needle 2, the front center line of the flame spraying seat 11 is perpendicular to the vertical center line of the ignition needle 2, two flame spraying openings 12 are arranged on the flame spraying seat 11 along the front center line of the flame spraying seat 11.
