Problems solved by technology

[0003] In the above-mentioned second fire cover structure, the mesh is generally set on the top of the fire cover by means of pressure riveting. At present, the material of the burner fire cover is generally copper alloy, and brass or copper with a copper content of about 53% is mainly used. The casting non-standard brass with a content of 57% has limited ductility of the copper alloy, which makes the covering width of the edge of the mesh on the edge of the top of the fire cover limited, which makes the mesh easy to fall from the fire cover; in addition, due to The covering width of the fire cover on the mesh is limited and the copper alloy is easily corroded after long-term use, which will also cause the mesh to fall from the fire cover

Embodiment 1

[0024] Such as Figure 1~4 Shown, a kind of combination burner cap, comprises the fire cap body 1 of top opening and the mesh sheet 2 that is located at this fire cap body 1 mouth. The mesh 2 has meshes 2. In this embodiment, the meshes 21 are evenly distributed on the mesh 2. The aperture of the mesh is 1.5-1.7mm, the spacing between the holes is 3.5-4.0mm, and the thickness of the mesh is 1.3-1.5mm. . The fire cover body 1 includes an inner seat body 12 and a sleeve body 11 sleeved outside the seat body 12, wherein the seat body 12 includes a chassis 124 and a ring wall 121 vertically arranged on the chassis 124 and having a central hole 123, And the mesh 2 rests on the ring wall 121 . In addition, the inner peripheral wall of the upper port portion of the casing 11 has an inwardly protruding annular flange 111 , and the edge of the mesh 2 is limited below the annular flange 111 . It can be seen that through the cooperation of the ring wall 121 and the ring flange 111, th...

Embodiment 2

[0028] Such as Figure 5 As shown, different from Example 1, the mesh 2 on the periphery of the recessed portion 22 in Example 2 is provided with four flame zones 23 in the circumferential direction, and secondary air inlet passages 24 are formed between adjacent flame zones 23, and the mesh The holes 21 are evenly distributed on the depressed portion 22 and each flame zone 23 , that is, the mesh holes 21 in Embodiment 2 are distributed in a quincunx shape. In this way, the secondary air can be supplied to the flame zone 23 and the mesh 21 of the recessed portion 22 through the secondary air inlet passage 24, so that the flame on the mesh 2 can be fully and efficiently burned.

Embodiment 3

[0030] Such as Figure 6 As shown, different from Embodiment 2, in this embodiment, there are eight flame regions 23 evenly distributed, and there are gaps between each flame region 23 and the recessed part 22, and each gap is combined to form a The secondary air circulation channel 25 is provided, and the width of the secondary air circulation channel 25 is 3-6 mm. After the air enters from the secondary air inlet channel 24, it can form a certain circulation in the secondary air circulation channel 25, so as to better provide secondary air for the combustion of the flame on the mesh 2. In addition, eight independent flame zones The setting also can make the flame on the mesh 2 burn more evenly, effectively avoiding the problem of sticky pot or undercooked food caused by uneven flame at the bottom of the pot during use.

Abstract

The invention relates to a combinative burner fire cover, which comprises a fire cover body and a reticular sheet, wherein the upper part of the fire cover body is open; the reticular sheet covers a mouth part of the fire cover body; the fire cover body comprises an internal seat body and a sleeve body which is arranged outside the seat body in a sleeving manner; the seat body comprises a chassis and an annular wall which is vertically arranged on the chassis and is provided with a center hole; the reticular sheet is placed on the annular wall; meanwhile, the inner circumferential wall of a mouth part at the upper end of the sleeve body is provided with an annular flange which is inwards protruded; the edge of the reticular sheet is limited below the annular flange. In comparison with the prior art, the combinative burner fire cover provided by the invention has the advantages that the reticular sheet and the fire cover body are fixed through the cooperative effect of the annular wall and the annular flange; the reticular sheet can be effectively prevented from falling off from the fire cover body, and also cannot fall off from the fire cover body after being used for a long term.

Description

technical field [0001] The invention relates to the field of burners, in particular to a combined burner fire cover. Background technique [0002] At present, burner fire covers on the market are generally divided into two types, one of which achieves stable and sufficient combustion through one or two circles of main flame holes, and the other is a burner fire cover with mesh. The cover is provided with a mesh to achieve the purpose of stabilizing the flame and burning. The burner fire cover with mesh is as the inner ring fire cover structure disclosed in the Chinese invention patent "Household Gas Stove Burner" with the application number 201310316588.7 (the application publication number is CN103438454A), and the patent number is ZL201220709118.8 (the authorized announcement number is CN202973098U) Chinese utility model patent "a kind of burner fire cover" discloses the burner fire cover structure, and the patent number is ZL201320882291.2 (authorization announcement num...
