Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figures 1 to 4, the burner fire lid in the present embodiment includes fire cover body 1, in the upper table of fire cover body 1
Face circumferentially forms the main fire groove of spaced radial distribution, and wherein, it is main that main fire groove includes the first main fire groove 11 and second
Fiery groove 12, the first main fire groove 11 and the second main fire groove 12 interval setting, and, the groove depth of the first main fire groove 11 is more than second
The groove depth of main fire groove 12, the length of the first main fire groove 11 is more than the length of the second main fire groove 12.
As shown in Fig. 2 being provided with a second main fire groove 12 between two the first main fire grooves 11, due to the second main fire groove 12
Not only shallow but also short, thus the area that the auxiliary air of the first main fire groove 11 supplements region B is relatively large, and then be conducive to the first main fire
The auxiliary air of groove 11 supplements, and the load that the second main fire groove 12 is shared is relatively fewer, and the auxiliary air of needs does not have the first master
After fiery groove 11 is so much, and auxiliary air adds to the first main fire groove 11, naturally also can add in the second main fire groove 12.This fire
The supplementary direction of the auxiliary air of lid is as denoted by the arrows in fig. 2.
Form upwardly extending retaining wall 121 in the outer ledge of the second main fire groove 12, by arranging retaining wall 121, permissible
Change second main fire groove 12 corresponding to go out fiery angle.In the present embodiment, the length of the height H of retaining wall 121 and the second main fire groove 12
Ratio between degree L is 1/7≤H/L≤1/2.Specifically, the height H of retaining wall 121 is 0.5mm≤H≤2mm, the second main fire groove
The fiery angle [alpha] that goes out corresponding to 12 is 80 ° of 40 ° of ＜ α ＜.
Self-assembling formation fire tooth 13 between first main fire groove 11 and the second main fire groove 12, fiery tooth 13 upper surface adjacent to second
The side of main fire groove 12 forms sunk type step 131.In the present embodiment, the submergence depth h of this sunk type step 131 is
0.2mm≤h≤1.0mm.
As shown in figure 5, after cover plate 2 covers, the position of the first main fire groove 11 is correspondingly formed long fire hole 5, the second main fire groove
12 position is correspondingly formed short fire hole 6, and the position of sunk type step 131 is correspondingly formed from stable flame hole 7, makes fire cover from stable flame hole 7
Can have from steady flame effect.
In addition, fiery passage 14, circle from fiery tooth 13 sprays are enclosed under being arranged right below of fiery tooth 13 on fire cover body 1
Fire, encloses fire under the fiery passage 14 of lower circle sprays, so, the integrative-structure that fire cover adopts upper circle fiery and lower circle fire is arranged with circle, make
Fire cover structure more simple, diameter diminishes, reduce processing and material cost.
Lower circle fire passage 14 in the present embodiment includes vertical passageway 141 and oblique from inside to outside from vertical passageway top
The slanted channel 142 of upper extension, wherein, vertical passageway 141 forms opening in the bottom of fire cover body 1, and slanted channel 142 is in fire
The lateral part of lid body 1 forms opening, and, this slanted channel 142 angle of inclination beta with respect to the horizontal plane is 40 ° of 0 ° of ＜ β ＜.
So, the fiery passage 14 of lower circle is the passage of bending, lower circle fire passage 14 from bottom inflow, from the opening of fire cover body 1 lateral part
Go out fire, lower circle fire can be buffered before ejection.
In addition, upper circle fire forms main burning ring, lower circle fire forms little pyrosphere, and little pyrosphere had both played the effect of small fire, and played again
The effect of steady fireworks, encloses fire burning with stably upper, can function well as steady fireworks by adjusting the lower primary air ratio enclosing fire
Effect, steady flame effect is ideal, there is not stable flame hole and easily blocks up problem, substantially increases the adaptability to source of the gas for the burner
As shown in fig. 6, the burner being provided with this fire cover includes pedestal 4, fire cover is using the integral type being arranged on pedestal 4
Fire cover, this integral type fire cover includes fire cover body 1, cover plate 2 and case ring 3.Spray from the lower circle fire passage 14 of fire cover lower floor
Lower circle fire and the double-deck steady fireworks of fire composition spraying from stable flame hole 7 from fire cover upper strata, make the steady flame effect of burner more preferable.
