AI Technical Summary
During use, traditional burners are prone to blockage of combustion holes due to condensation water and foreign matters, which affects combustion efficiency and safety. In addition, existing stainless steel or copper burners still have the risk of condensation water dropping.
The copper combustion head is designed with an inner groove on its outer layer. The combustion hole is located at the bottom of the groove and a flare-shaped inner layer is adopted to avoid condensation water and foreign matters entering. It is combined with an intermediate platform structure to prevent water accumulation.
It improves the safety and service life of the burner, reduces the failure rate, and extends the service life of the burner.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of burners, in particular to an improved burner structure. Background Technique
[0002] After a period of use, the traditional cast iron burner will rust due to condensed water dripping on the burner, resulting in the gradual reduction of the fire holes, leading to a decline in efficiency and even problems such as poor flame transmission.
[0003] Subsequently, stainless steel or copper burners emerged. Although the rust problem was solved, there was still a risk of condensed water dripping into the fire holes, resulting in abnormal operation of the burner. This is mainly because when the water heater starts heating from cold water, due to the low temperature of the flue pipe, a lot of condensed water will form on the inner wall of the flue pipe during heating, and even rust impurities will fall down together. When it falls, it will directly fall into the fire holes, causing the fire holes to be blocked and abnormal combustion. Content of the Utility Model
[0004] The purpose of the utility model is to provide an improved burner structure to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: An improved burner structure, including an igniter and a combustor, the igniter and the combustor are connected together through a workpiece, and further includes a burner, the igniter and the combustor are arranged on one side of the burner, the burner includes a combustion head and a chassis, the combustion head is installed on the chassis, an air inlet pipe is arranged on one side of the chassis, the combustion head is of a sandwich structure, the sandwich structure includes an inner layer and an outer layer, a through hole is arranged at the center of the chassis, the inner layer is connected to the through hole, the outer layer is connected to the outer edge of the chassis, and a plurality of circumferentially distributed combustion holes are arranged on the outer layer.
[0006] Preferably, the combustion head is made of copper.
[0007] Preferably, an inner groove is arranged on the outer wall of the outer layer of the combustion head, and the combustion holes are arranged at the bottom of the inner groove.
[0008] Preferably, the inner side is in the shape of a flared mouth, and the tip of the flared mouth shape faces downward.
[0009] Compared with the prior art, the beneficial effects of the utility model are: The utility model solves the combustion problem caused by condensed water or foreign objects entering the combustion holes by arranging an inner groove in the burner, improves the safety of the burner, and prolongs the service life of the burner.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0014] Please refer to Figure 1-2 , the present utility model provides a technical solution: an improved burner structure, including an igniter 1 and a combustion supporter 2, the igniter 1 and the combustion supporter 2 are connected together through a workpiece, and further includes a burner 3, the igniter 1 and the combustion supporter 2 are arranged on one side of the burner 3, the burner 3 includes a combustion head 4 and a chassis 5, the combustion head 4 is installed on the chassis 5, an air inlet pipe 6 is arranged on one side of the chassis 5, the combustion head 4 is a sandwich structure, and the sandwich structure includes an inner layer 41 and an outer layer 42. A through hole 51 is arranged at the center of the chassis 5, the inner layer 41 is connected to the through hole 51, the outer layer 42 is connected to the outer edge of the chassis 5, and a plurality of circumferentially distributed combustion holes 7 are arranged on the outer layer 42.
[0015] The combustion head 4 is made of copper parts, which can effectively solve the problem of rusting of cast iron in the traditional technology.
[0016] An inner groove 43 is arranged on the outer wall of the outer layer of the combustion head 4, and the combustion holes 7 are arranged at the bottom of the inner groove 43. The combustion holes 7 are evenly arranged on the side of the combustion head 4, and at the bottom of the inner groove 43 where the combustion holes 7 are located, an eaves design structure is made directly above the inner groove 43. This structure can directly prevent foreign objects or condensed water from entering the combustion holes 7, thereby increasing the service life of the burner and reducing the use failure rate.
[0017] The inner layer 41 is in the shape of a flared mouth, and the tip of the flared mouth shape faces downward. Different from the traditional burner, the structure of canceling the middle platform is adopted, and the inner ring adopts an inclined structure, so that condensed water or foreign objects will not accumulate on the burner.
