Description

Novel ignition needle and combustor

Technical Field

The utility model relates to the field of gas stoves, in particular to a novel ignition needle and a burner.

Background

The existing gas stove is ignited by an igniter, and the igniter extends to the gas outlet hole by an ignition needle, so that the gas is ignited by the tip discharge of the igniter.

For example, the patent document with publication number CN210891781U discloses an ignition needle, including discharge head and needle body, the outside cover of needle body is equipped with ceramic interior sleeve pipe, the needle body lower extreme is connected with the wire, still includes: the auxiliary ceramic tube is sleeved on the guide wire and is connected with the lower end of the ceramic inner sleeve.

For another example, a patent document with publication number CN212339315U discloses a gas stove ignition needle, which relates to the technical field of gas stove ignition needles, and comprises an ignition needle body, wherein the ignition needle body comprises a discharge end, and the discharge end faces a fire hole; the cross-sectional area of the discharge end gradually decreases in a direction toward the fire hole.

However, in the above-mentioned technique, one end of the ignition needle extends to a certain distance outside the ceramic sleeve, and the extended portion is spark with the surrounding metal body, so that it is difficult to ensure only the tip discharge, resulting in ignition failure.

Therefore, a novel ignition needle is provided for solving the technical problems.

Disclosure of Invention

In order to solve the technical problems, the utility model aims to: provided is a novel ignition needle which can discharge only through a tip and has high ignition efficiency.

The utility model adopts the technical scheme that: a novel ignition needle comprising: the body, the body includes the pottery cover, the tip of pottery cover is equipped with the recess, the middle part embedding of pottery cover is run through and is installed the needle body, the one end that the needle body is located the recess is the discharge end, the discharge end extends outside the recess.

The utility model provides a combustor, includes ignition needle, still include furnace end (2), furnace end (2) are in including distributor (21) and lid fire lid (22) on distributor (21), be equipped with breach (211) on distributor (21), needle body (13) are located in breach (211).

As a further improvement, openings are arranged on the outer side and the top of the notch (211).

As a further improvement, the fire cover (22) is made of ceramic porous plates.

As a further improvement, an installation seat (3) is fixed on the outer wall of the lower part of the distributor (21), and the lower part of the body (1) is installed on the installation seat (3).

As a further improvement, a thermocouple (4) is also arranged on the mounting seat (3), and the thermocouple (4) is arranged on the outer side of the body.

The beneficial effects of the utility model are as follows: through setting up the recess at the tip of ceramic sleeve, the root that makes the needle body outstanding ceramic sleeve end can not send the spark to the metal body around, guarantees that the spark sends from the discharge end, improves ignition efficiency.

Drawings

The utility model is further illustrated by the following description and examples of the embodiments in conjunction with the accompanying drawings.

FIG. 1 is a schematic view of a novel ignition needle provided by the utility model;

fig. 2 is a schematic structural view of a burner provided by the present utility model.

In the figure: 1-body, 11-ceramic sleeve, 12-recess, 2-furnace end, 21-distributor, 211-breach, 22-fire lid, 3-mount pad, 4-thermocouple.

Detailed Description

Reference will now be made in detail to the present embodiments of the present utility model, examples of which are illustrated in the accompanying drawings, wherein the accompanying drawings are used to supplement the description of the written description so that one can intuitively and intuitively understand each technical feature and overall technical scheme of the present utility model, but not to limit the scope of the present utility model.
