Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a thin burner. Background Art

[0002] The bottom-inlet fire burner of the inner-outer type (Siemens type) currently on the market has a burner cover assembly divided into an upper fire cover and a lower fire cover bottom due to its structure. Since the airflow at the bottom of the fire cover must be dispersed from the middle to the large fire cover on the outer circle, the bottom of the fire cover is a hollow structure with a cavity. This cannot be formed as a whole using ordinary processes, and can only be assembled after the parts are processed using a split structure. Not only is the processing procedure complicated, but the appearance is also not beautiful.

[0003] At the same time, the bottom of the fire cover adopts a split structure, which is prone to deformation when used for a long time, affecting the service life of the product. Utility Model Content

[0004] The utility model aims to provide a technical solution for a thin burner in view of the deficiencies in the prior art. The outer ring fire cover seat, the inner ring fire cover seat and the gas distribution channel are formed by integral processing, which not only simplifies the processing procedure but also has a beautiful appearance. Even after long-term use, deformation will not occur, thereby increasing the service life of the product.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A thin burner comprising

[0007] A base;

[0008] Features:

[0009] The base includes an outer ring fire cover seat, an inner ring fire cover seat and an air separation channel that are integrally formed. The inner ring fire cover seat is connected to the outer ring fire cover seat through at least one air separation channel. The outer ring fire cover seat, the inner ring fire cover seat and the air separation channel formed by integrally forming the outer ring fire cover seat not only simplify the processing procedure, but also have a beautiful appearance. Even after long-term use, deformation will not occur, thereby increasing the service life of the product.

[0010] Furthermore, the base is made of stainless steel, which reduces manufacturing costs.

[0011] Furthermore, the outer ring fire cover seat is provided with an outer ring fire dividing cavity, and the inner ring fire cover seat is provided with an air dividing cavity, which is connected to the outer ring fire dividing cavity through an air dividing channel for conveying mixed gas to the outer ring fire dividing cavity.

[0012] Furthermore, the air distribution channel includes a top surface and a bottom surface. The top surface is inclined upward from one side of the inner ring fire cover seat to the other side of the outer ring fire cover seat, and the bottom surface is horizontally arranged between the inner ring fire cover seat and the outer ring fire cover seat, which is conducive to uniform distribution of airflow.

[0013] Furthermore, a step is provided on the inner wall of the outer ring fire separation chamber away from the gas separation channel, and the mixed gas can flow along the step after coming out of the gas separation channel, so as to evenly distribute the mixed gas along the outer ring fire separation chamber.

[0014] Furthermore, the inner ring fire cover seat also includes an inner ring fire dividing chamber separated from the air dividing chamber. A dividing ring is integrally formed between the inner ring fire dividing chamber and the air dividing chamber. The dividing ring protrudes toward one side of the air dividing chamber, so that the inner ring fire dividing chamber and the outer ring fire dividing chamber can independently transport the mixed gas without affecting each other, thereby improving safety and reliability during use.

[0015] Furthermore, the outer ring fire cover seat and the inner ring fire cover seat cooperate to form an air channel for secondary transport of air to improve combustion efficiency.

[0016] Furthermore, an arc-shaped groove is provided in the air passage near the edge of the inner ring fire cover seat for positioning and assembling the ignition needle or the thermocouple.

[0017] Furthermore, it also includes an inner ring fire cover, which is detachably connected to the inner ring fire cover seat through a first fulcrum fastening assembly to prevent the inner ring fire cover from being deformed due to heat.

[0018] Furthermore, it also includes an outer ring fire cover, which is detachably connected to the outer ring fire cover seat through a second fulcrum fastening assembly to prevent the outer ring fire cover from being deformed due to heat.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] 1. The utility model forms the outer ring fire cover seat, the inner ring fire cover seat and the gas distribution channel through integrated processing, which not only simplifies the processing procedure but also has a beautiful appearance. In the case of long-term use, deformation will not occur, thereby improving the service life of the product.

[0021] 2. The air distribution channel includes a top surface and a bottom surface. The top surface is inclined upward from one side of the inner ring fire cover seat to the side of the outer ring fire cover seat, and the bottom surface is horizontally arranged between the inner ring fire cover seat and the outer ring fire cover seat, which is conducive to uniform distribution of airflow.

[0022] 3. A step is provided on the inner wall of the outer ring fire-dividing cavity away from the gas-dividing channel. After the mixed gas comes out of the gas-dividing channel, it can flow along the step, so as to evenly distribute the mixed gas along the outer ring fire-dividing cavity.

[0023] 4. The design of the first fulcrum fastening assembly and the second fulcrum fastening assembly can prevent the inner ring fire cover and the outer ring fire cover from being deformed by heat, thereby extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS
