Detailed Description
Further description will be made with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2 and 3, the present embodiment provides a high efficiency ignition needle 100 of a gas burner, the ignition needle 100 including a head portion 10 extending in a horizontal direction and a tail portion 20 extending in a vertical direction, so that the ignition needle 100 is shaped like a "7"; the head 10 is suspended above the gas burner for discharging to generate an arc to ignite the gas, and the tail 20 is inserted into the gas burner for receiving electricity to supply power to the head 10. The tail 20 is wholly or partly surrounded by a housing 21 made of ceramic material. Specifically, the head 10 extends toward the gas burner (i.e. downward in the drawing) to form a bump 11, and based on the principle of tip discharge, the ignition needle 100 discharges to the gas burner through the bump 11, the arc is led out between the bump 11 and the gas burner, and the arc is not easy to run. Therefore, the generated arc can always face the injection port of the fuel gas, so that the high-efficiency ignition can be realized.
Since the gas range is very easily contaminated with dirt and oil water in use, the arc easily drifts along the surface of the housing 21 when the ignition needle 100 discharges, thereby avoiding the injection port to cause abnormal ignition. Based on this, in this embodiment, an isolating knot 30 is disposed at the junction of the head 10 and the tail 20 of the ignition needle 100, and as shown in fig. 2, the isolating knot 30 is also made of ceramic material, and includes an isolating ring 31 with a diameter larger than that of the housing 21 and an isolating block 32 extending from the isolating ring 31 toward the protruding point 11, and the isolating knot 30 is used for blocking the protruding point 11 from discharging to the gas burner via the surface of the housing 21. The principle is that when the surface of the ignition needle 100 is stained with oil stains, the distance from the salient point 11 to the surface of the gas burner through the shell 21 becomes larger due to the existence of the isolation knot 30, so that the electric arc generated by discharging the salient point 11 to the gas burner will not pass through the surface of the shell 21, but directly generate between the salient point 11 and the gas burner, thereby igniting the gas injected from the injection port.
In order to avoid that the ignition needle 100 directly discharges to the gas burner at the cracking position after the shell 21 is cracked, the shell 21 of the embodiment is provided with a double-layer structure, and when the outer layer of the shell 21 is cracked, the inner layer still wraps the tail portion 20 of the ignition needle 100, so that the tail portion 20 of the ignition needle 100 cannot discharge to the gas burner. Similarly, when the inner layer of the casing 21 is cracked, the outer layer still wraps the tail portion 20 of the ignition needle 100, so that the tail portion 20 of the ignition needle 100 does not discharge to the gas burner.
In order to simplify the processing technology, the outer layer of the shell 21 and the isolating knot 30 are integrally formed, or the isolating knot 30 is of a double-layer structure, the outer layer of the shell 21 and the outer layer of the isolating knot 30 are integrally formed, and the inner layer of the shell 21 and the inner layer of the isolating knot 30 are integrally formed.
Typically, the ignition pin 100 is a metal rod, and when the electric wire is connected, the electric wire is often directly welded to the end face or the side face of the tail portion 20 in the prior art, which easily causes the disconnection, resulting in poor contact and even falling of the electric wire. The end of the tail portion 20 of the present embodiment is electrically connected by a connector 40. Specifically, the connector 40 has a ferrule 41 at one end into which the end of the tail portion 20 is inserted and soldered or riveted thereto, and a terminal 42 at the other end soldered to an electric wire. In this way, the connection between the ignition needle 100 and the electric wire is more secure.
In addition, since the position of the arc generated by the discharge is uncertain and even moves when the cylindrical ignition needle 100 is stained with the mixture of oil and water, the bottom surface of the head 10 of the ignition needle 100 is set to be a plane in this embodiment, so that the arc is only generated at the position of the salient point 11 and does not move when the ignition needle 100 discharges, thereby always ensuring that the arc can be aligned with the injection port and achieving the effect of efficient ignition.
Referring to fig. 4, the present embodiment further provides a side ignition device 1000 of a gas burner, including an ignition needle 100, a sensing needle 200, a ground needle 300 and a base 400, where the ignition needle 100 and the sensing needle 200 are inserted into the base 400 and are electrically connected from the lower side of the base 400, the ignition needle 100 and the ground needle 300 are oppositely arranged, and the ignition needle 100 directly discharges to the ground needle 300. The ignition needle 100 of the present embodiment is a high efficiency ignition needle as shown in fig. 2 and 3.
In order to improve the reliability of the product, the structure of the sensing needle 200 and the ignition needle 100 is the same, and a ground needle 300 is also disposed below the sensing needle 200. Meanwhile, the side ignition device 1000 further includes a flameout protection circuit (not shown) electrically connected to the ignition needle 100 and the sensing needle 200 and adapted to enable the sensing function of the ignition needle 100 when the sensing needle 200 is detected to be failed or enable the ignition function of the sensing needle 200 when the ignition needle 100 is detected to be failed. Thus, when any one of the functions of the ignition needle 100 and the sensing needle 200 is disabled, the other one can be used instead, so that the service life and the reliability of the product can be remarkably prolonged.
In summary, according to the utility model, the protruding point is extended from the head of the ignition needle towards the gas burner, and the protruding point discharges towards the gas burner, so that the problem that the ignition needle cannot normally ignite due to the fact that the arc moves during discharging can be avoided, the ignition efficiency can be greatly improved, and the use experience of consumers can be effectively improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
