Description

[Detailed Description of the Invention] The present invention relates to a igniter nozzle, and an object of the present invention is to provide a igniter nozzle structure in which the nozzle portion is particularly long so that it is easy to ignite gas appliances and the like.

As shown in FIG. 1, the conventional igniter has a burner 6' mounted inside an insulator 7' via a lug plate 8, one end of a high voltage lead wire 9 connected to the lug plate 8, and one end of the high voltage lead wire 9 connected to the lug plate 8. One end of a flexible gas pipe 10 is fitted into one end of the burner 6', and the lug plate 8 and the end of the burner 6' are connected to a silicone rubber 11 which is an insulating material.
The burner 6' is hardened and attached to the insulator 7'.
The insulator 7' to which the lug plate 8, high-voltage lead wire 9, and gas pipe 10 are attached is attached to the piece 2 that protrudes from the head of the cylinder 2'.
At the same time, the other end of the gas pipe 10 is connected to the nozzle 5', and the other end 9a of the high voltage lead wire 9 is connected to the high potential part of the high voltage generating element provided inside the main body. ' was fitted onto the tip 1 of the main body to form the crater.

In the conventional structure described above, processing around the insulator 7' is extremely complicated and time-consuming, and processing of the high voltage lead wire 9 is troublesome. Moreover, burner 6′
Since the gas pipe 10 connecting the nozzle 5' and the nozzle 5' is flexible, in a igniter with a relatively long nozzle part, the gas is bent extremely inside the cylinder body 2', causing the gas to reach the burner 6'. They have various drawbacks such as poor flow and poor ignition, and they require many man-hours to assemble and tend to be expensive. The present invention solves the above-mentioned drawbacks and provides a nozzle structure for a igniter that is extremely easy to assemble and can easily ignite gas appliances, etc. even if the nozzle portion is relatively long.

Embodiments will be described in detail below with reference to the drawings.

FIG. 2 is an enlarged sectional view of the mouth of the igniter according to the present invention.

Reference numeral 1 denotes the tip of a main body (not shown), which is molded from a resin material, and inside this main body, although not shown, a gas tank, a high voltage generating element, a switch mechanism, etc. are installed. 2 is a cylinder. This cylindrical body 2 is a relatively long metal cylindrical body (approximately 20 cm), and has an air hole 2a in the head and a low voltage terminal 2 with a part of the head cut out.
b and a protruding piece 2c protruding inwardly are provided at the bottom 2.
d can be freely fitted onto the tip 1 of the main body. A is the burner assembly. This burner assembly A consists of an elongated metal conduit 4 covered with an insulating tube 3.
A nozzle 5 is press-fitted into one end and a burner 6 is connected to the other end. 7 is an insulator. This insulator 7 can be attached to the burner 6, inserted from the bottom 2d of the cylinder 2, and positioned by the protruding piece 2c. Therefore, the burner assembly A is inserted from the bottom 2d of the cylindrical body 2 together with the insulator 7 attached to the burner 6, the insulator 7 is positioned by the protruding piece 2c, and the tip of the burner 6 is aligned with the low voltage terminal. The nozzle 5 is fixed to the distal end 1 of the main body, and the cylindrical body 2 is fitted to the distal end 1 of the main body and connected to the low voltage side of the high voltage generating element. On the other hand, the nozzle 5 is connected to a gas tank provided in the main body and further to the high-pressure side of a high-voltage generating element, thereby distributing power to the burner assembly A at a high potential and the cylinder body 2 at a low potential.

With the above configuration, when igniting, the valve of the gas tank is opened by operating the switch of the switch mechanism installed inside the main body, and the gas in the tank is guided to the burner 6 through the nozzle 5 and the conduit 4. At the same time, this switch operation causes the high voltage generating element to generate a high voltage, and this high voltage is led to the tip of the burner 6 via the nozzle 5 and the conduit 4, and is then led to the low voltage terminal of the cylinder 2 which is at the low voltage. 2b, a spark is discharged and the gas is ignited.

As mentioned above, compared to conventional products, the present invention has the following advantages: 1. Since the burner 6 is only attached to the insulator 7, there is no need to harden the high-pressure lead wire 9 and gas pipe 10 with silicone rubber 11 as in the conventional product, and the handling is simple. be.

2. Since the high potential is led to the tip of the burner 6 via the nozzle 5 and the conduit 4, the high voltage lead wire 9 is unnecessary.

3 Since the nozzle 5 and the burner 6 are connected by the elongated and robust metal conduit 4, there is no possibility of bending and ignition failure as with the conventional gas pipe 10, and the nozzle part can be made as long as desired. Can easily ignite gas appliances, etc.

4 As for assembly, as mentioned above, burner assembly A
After attaching the insulator 7 to the burner 6 (nozzle 5 and burner 6 connected by a covered conduit 4) and setting it inside the cylinder 2,
At the same time as the burner 5 is fitted to the tip 1 of the main body, the burner 5 is connected to the gas tank and the high voltage part of the high voltage generating element and assembled at once, which has various effects such as reducing assembly man-hours and improving productivity. It is.
