Description

Technical Field

[0001] The utility model relates to the technical field of ignition needles, in particular to an ignition needle protection structure. Background Art

[0002] In the existing design of the stove, a sensing needle is designed on the ignition needle. If the sensing needle senses a certain temperature, it will be transmitted to the solenoid valve, and the solenoid valve will ventilate the main fire handle. If the ignition needle does not burn the sensing needle, the sensing needle will not sense the temperature and will be powered off to achieve flameout protection, avoiding safety problems caused by forgetting to turn off the handle or not turning the handle tightly.

[0003] The existing sensing needle is bent near the ignition needle head, and the sensing needle body is bent to extend above the ignition needle head. With this design, the length of the ignition needle head is forced to be shortened, and the sensing needle is long, causing inconvenience in installation and use. Utility Model Content

[0004] The utility model aims to provide an ignition needle protection structure to solve the problem in the background art that the length of the ignition needle tip is forced to be shortened due to the installation of a sensing needle of a flameout protection device.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An ignition needle protection structure is applied to an ignition needle. A needle head is provided on one side of the end of the ignition needle, and a sensing needle is provided on the other side of the end of the ignition needle. The upper end of the sensing needle is integrally connected to an arc-shaped metal part, and the arc-shaped metal part is located at the top of the needle head. Convex bodies are provided on both sides of the arc of the arc-shaped metal part.

[0007] As a further description of the above technical solution:

[0008] The height of the sensing needle is smaller than the height of the needle head.

[0009] As a further description of the above technical solution:

[0010] A vertical body is extended from one end of the arc-shaped metal piece connected to the sensing needle.

[0011] As a further description of the above technical solution:

[0012] The arc-shaped metal piece and the vertical body are both flat.

[0013] As a further description of the above technical solution:

[0014] The convex body is a hemispherical structure.

[0015] As a further description of the above technical solution:

[0016] The adjacent convex bodies are arranged at staggered positions.

[0017] Compared with the prior art, the utility model provides an ignition needle protection structure, which has the following beneficial effects:

[0018] 1. In the utility model, the length of the sensing needle is shortened, and an arc-shaped metal piece is installed at its end. The arc-shaped metal piece has a large surface area in contact with the needle tip, but occupies a small height space. In this way, the needle tip can realize flameout protection sensing without excessively shortening its length. The needle tip can be designed and used according to the conventional length;

[0019] 2. In the present invention, the convex body designed on the arc-shaped metal piece further increases the outer surface of the arc-shaped metal piece in contact with the burner, accelerates the temperature rise of the arc-shaped metal piece, and realizes rapid temperature transfer to the position of the sensing needle.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 2 The utility model provides an ignition needle protection structure, which is applied to an ignition needle 1. A needle head 2 is provided on one side of the end of the ignition needle 1, and a sensing needle 3 is provided on the other side of the end of the ignition needle 1. The upper end of the sensing needle 3 is integrally connected to an arc-shaped metal part 4, and the arc-shaped metal part 4 is located at the top of the needle head 2. The arc-shaped metal part 4 has convex bodies 5 on both sides of the arc.

[0027] Specifically, Figure 1 As shown, the height of the sensing needle 3 is smaller than that of the needle head 2 , and a vertical body is extended from one end of the arc-shaped metal piece 4 connected to the sensing needle 3 , so that the height of the needle head 2 does not need to be shortened too much, which facilitates the installation of the arc-shaped metal piece 4 .

[0028] Specifically, the arc-shaped metal member 4 and the vertical body are both flat, which does not affect the fire head and has a large contact area with the fire head.

[0029] Specifically, Figure 2 As shown, the convex body 5 is a hemispherical structure, and the positions of adjacent convex bodies 5 are staggered to increase the contact surface between the arc-shaped metal part 4 and the burner, so as to quickly transfer the heat to the position of the induction needle 3. The staggered design allows the burner to directly rush to each convex body 5.

[0030] Working principle:

[0031] After the needle 2 of the ignition needle 1 is ignited, the arc-shaped metal part 4 will be heated, and the arc-shaped metal part 4 will quickly transfer the heat to the sensing needle 3, and then the solenoid valve will ventilate the main fire handle. The shape of the arc-shaped metal part 4 and the design of the convex body 5 can allow the arc-shaped metal part 4 to quickly and widely contact the ignition needle spark head, thereby accelerating the heat transfer speed.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
