Description

A kind of net sheet type burner fire lid

Technical field

The utility model is related to burner arts, more particularly to a kind of net sheet type burner fire lid.

Background technology

Burner fire lid in the market is generally divided into two kinds, one of which by a circle or the main glory hole of two circles come Stable, sufficiently burning is reached, another kind is the burner fire lid with mesh sheet, it is steady to reach that mesh sheet is covered with this kind of fire cover Flame, the purpose of burning.(application publication number is burner fire lid with mesh sheet such as Application No. 201310316588.7 CN103438454A Chinese invention patent)《Burner for household gas range》Disclosed interior ring fire cover structure, Patent No. The Chinese utility model patent of ZL201220709118.8 (Authorization Notice No. is CN202973098U)《A kind of burner fire lid》 The China of disclosed burner fire lid structure, Patent No. ZL201320882291.2 (Authorization Notice No. is CN203671602U) Utility model patent《A kind of infrared burner of household gas stove》Disclosed burner structure etc..

In above-mentioned second fire cover structure, mesh sheet lid typically by way of pressing is located at the top of fire cover, current combustion The material of device fire cover is generally copper alloy, mainly adopt copper content for 53% or so brass or copper content be 57% to draw casting Nonstandard brass, the ductility of copper alloy is limited so that all cladding limited widths along to mesh sheet edge in fire cover top, so as to cause Mesh sheet easily drops from fire cover；Further, since fire cover is to easy after the cladding limited width and copper alloy Long-Time Service of mesh sheet It is corroded, also results in mesh sheet and drop from fire cover.

The content of the invention

First technical problem to be solved in the utility model is that providing one kind can be prevented effectively from for prior art The net sheet type burner fire lid that mesh sheet drops.

Second technical problem to be solved in the utility model is that a kind of abundant, combustion of burning is provided for prior art Burn efficient net sheet type burner fire lid.

The utility model solve the technical scheme that adopted of above-mentioned technical problem for：A kind of net sheet type burner fire lid, bag The fire cover body and lid for including open topped is located at the mesh sheet of the fire cover body oral area, it is characterised in that the fire cover body and net Piece is connected by snap ring, and the section of the snap ring is in C fonts, and the upper end of C font openings is first pressure at the edge that card pushes down mesh sheet Ring portion, the lower end of C font openings is the second pressure ring portion that card pushes down fire cover body oral area periphery wall.

Preferably, the oral area periphery wall of the fire cover body has outwardly flange, the second pressure of the snap ring Ring portion is blocked and pushes down the flange.

Further, for convenience of the processing of the collar, preferably, the snap ring has breach, and the arc length of the breach for card The 1/30～1/26 of ring girth, the setting of breach can also facilitate snap ring with mesh sheet and the assembly and connection of fire cover body.

For convenience of the assembling of the burner fire lid, while mesh sheet can also be more stably arranged in fire cover, preferably, The fire cover body is internally provided with the pedestal with centre bore, and there is corresponding depressed part to match in the base in the mesh sheet In the centre bore of seat.

Preferably, be circumferentially provided with least two flame zones in the mesh sheet of the depressed part periphery, adjacent flame zone it Between form auxiliary air air intake passage, the mesh is distributed on depressed part and each flame zone；Air enters logical by auxiliary air Road entrance, so as to auxiliary air can be supplemented for the mesh on flame zone and depressed part, it is ensured that the flame in mesh sheet fully, efficiently fires Burn.

Further, to make auxiliary air supplementary result more preferably, preferably, the flame zone is 4～8, also, each fire Gap is left between flame area and depressed part, each combinations of gaps is formed along the circumferentially disposed auxiliary air circulation canal of depressed part； To be so designed that also can make the flame combustion in mesh sheet more uniform.

Further, the width of the auxiliary air circulation canal is 3～6mm, so as on the basis for ensureing smoothly to pass fire On, can effectively realize the circulation of auxiliary air.

Preferably, the aperture of the mesh is 1.5～1.7mm, pitch of holes is 3.5～4.0mm.

Preferably, the thickness of the mesh sheet is 1.3～1.5mm.

Compared with prior art, the utility model has the advantage of：Fire cover body described in the utility model is led to mesh sheet Snap ring connection is crossed, the section of the snap ring is in C fonts, and the upper end of C font openings is the first pressure ring portion at the edge that card pushes down mesh sheet, The lower end of C font openings is the second pressure ring portion that card pushes down fire cover body oral area periphery wall；It can be seen that can be simultaneously to net by snap ring Piece and fire cover body are fixed, therefore can be prevented effectively from mesh sheet and drop from fire cover body, and Long-Time Service also will not be from fire cover Drop on body.

Specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

Embodiment 1：

As shown in Figures 1 to 3, a kind of fire cover body 1 and lid of net sheet type burner fire lid, including open topped is located at the fire The mesh sheet 2 of the oral area of lid body 1, is evenly equipped with mesh 20 in the mesh sheet 2, above-mentioned fire cover body 1 is fixed with mesh sheet 2 by snap ring 3.On The aperture for stating mesh is 1.5～1.7mm, and pitch of holes is 3.5～4.0mm, and the thickness of mesh sheet is 1.3～1.5mm.

In the present embodiment, the section of the snap ring 3 is in C fonts, and the upper end of C font openings is the edge that card pushes down mesh sheet 2 First pressure ring portion 31, the lower end of C font openings is the second pressure ring portion 32 that card pushes down the oral area periphery wall of fire cover body 1.Further, The oral area periphery wall of fire cover body 1 has an outwardly flange 4, and the second pressure ring portion 32 of the snap ring 3 blocks that to push down this convex Edge 4.It can be seen that by the first pressure ring portion 31 and the second pressure ring portion 32 in snap ring 3 fire cover body 1 and mesh sheet 2 can be made to form stable It is fixed, the problem that mesh sheet 2 easily drops in effectively solving prior art.

Additionally, snap ring 3 also has breach 5, and the arc length of the breach 5 is the 1/30～1/26 of the girth of snap ring 3, breach 5 Setting can not only facilitate the processing of the collar, while the collar can also be facilitated with mesh sheet 2 and the assembly and connection of fire cover body 1.Meanwhile, The pedestal 6 being internally provided with centre bore of above-mentioned fire cover body 1, and have and the corresponding depressed part of pedestal 6 in mesh sheet 2 21 matchings are in the centre bore of the pedestal 6.

Embodiment 2：

As shown in figure 4, as different from Example 1, circumferentially it is equipped with the mesh sheet 2 of the periphery of depressed part 21 in embodiment 2 Four flame zones 23, form auxiliary air air intake passage 24 between adjacent flame zone 23, mesh 21 is distributed on depressed part 22 and each On flame zone 23, i.e., the mesh 20 in embodiment 2 is distributed in plum blossom-shaped.Can be flame so by auxiliary air air intake passage 24 The mesh 20 of area 23 and depressed part 22 supplements auxiliary air so that the flame in mesh sheet 2 fully, efficient burning.

Embodiment 3：

As shown in figure 5, as different from Example 2, the present embodiment Flame area 23 is equally distributed eight, each flame Gap is left between area 23 and depressed part 21, each combinations of gaps forms logical along the circumferentially disposed auxiliary air circulation of depressed part 21 Road 25, the width of auxiliary air circulation canal 25 is 3～6mm.After air is entered by auxiliary air air intake passage 24, can be secondary Air circulation duct 25 forms certain circulation, and so as to the burning preferably for flame in mesh sheet 2 auxiliary air is provided, this Outward, the setting of eight independent flame zones can also make the flame combustion in mesh sheet 2 more uniform, be prevented effectively from the fire in the bottom of a pan when using Not yet done problem that flame is uneven and being burned of causing or food boil.
