Embodiment 1

[0018] Example 1, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the burner outer fire cover includes an outer fire cover body 1 with a plurality of main fire passages 11, and the lower end surface of the outer fire cover body 1 has an air mixing chamber 2, which communicates with the main fire passages 11, and the main fire passage 11 is connected to the main fire passage 11. The fire channel 11 forms a main fire hole 12 on the outer end surface of the outer fire cover body. The outer fire cover body 1 is located below the main fire channel 11 and forms an annular flame-stabilizing channel 13 around the circumferential direction. The outer end of the flame-stabilizing channel 1 is outside the outer fire cover body. A flame-stabilizing ring 14 is formed on the side, and the inner end communicates with the gas mixing chamber 2 . Further, the inner end of the flame-stabilizing channel 13 is connected with a plurality of independent air intake channels 15 vert...

Embodiment 2

[0022] Example 2, such as Figure 5 As shown, the outer fire cover body 1 is located above the main fire passage 11 and forms an annular flame-stabilizing passage 13 around the circumferential direction, and the length direction of the section of the main fire passage 11 and the flame-stabilizing passage 13 forms an acute angle β, and β is 30° . Refer to Example 1 for other structures.

Abstract

An outer burner cap of a burner comprises an outer burner cap body with a plurality of main flame channels. The lower end of the outer burner cap is provided with a gas mixing chamber communicated with the main flame channels. The main flame channels are provided with main flame holes on at least one of the inner side and the outer side of the outer turner cap body. The outer burner cap is characterized in that the outer flame cap body above or below the main flame channels peripherally forms a circular flame-stabilizing channel, and the outer end of the flame-stabilizing channel forms a flame stabilizer ring on the outer side or inner side of the outer burner cap body. The inner end of the flame-stabilizing channel is communicated with the gas mixing chamber. Compared with the prior art, the outer burner cap has the advantage that the flame-stabilizing channel at the lower edges of the main flame holes can well 'stabilize' flame from the main flame holes during burning so as to stabilize burning.

Description

technical field [0001] The invention relates to an outer fire cover of a burner, which belongs to the technical field of combustion equipment. Background technique [0002] Common household burners generally have an outer fire cover and an inner fire cover to stabilize the flame. The existing burner outer fire cover structure generally includes an outer fire cover body with a plurality of main fire channels. The main fire hole is formed on the outer end surface of the body. This type of patent document can refer to the Chinese utility model patent "A Conical Flame Cover for a Gas Stove Burner" (authorized announcement number: CN2842216Y) whose patent number is ZL200520014838.2, and the Chinese utility model whose patent number is ZL201120246965.0. Utility model patent "A burner fire cover" (authorized announcement number is CN202149492U). The single main flame hole combustion method disclosed above has the disadvantages that the flame is easy to jump after combustion and ...
