Abstract
The utility model relates to an improved furnace head fire cover which comprises a fire cover body mounted on a furnace head; a ring-shaped air cavity is formed in the fire cover body, the side wall of the fire cover body is provided with a plurality of outer ring fire holes formed in a tilting way in the circumferential direction, the outer ring fire holes are communicated with the ring-shaped air cavity, a ring-shaped groove is formed in the side wall of the fire cover body above the outer ring fire holes, a plurality of flame increasing holes communicated with the ring-shaped air cavity are formed in the ring-shaped groove in a tilting way, and the flame increasing holes and the outer ring fire holes form included angles alpha mutually; in the furnace head fire cover adopting the structure, by additionally arranging the ring-shaped groove above the outer ring fire holes, and forming the flame increasing holes in the ring-shaped groove, the flame increasing holes and the outer ring fire holes are all used for flame ejection, so as to form stronger burning flame, the fuel gas is in full contact with air, and the combustion efficiency is improved.
Description
Technical field
The utility model relates to a kind of stove burner fire cover technical field, especially a kind of improved stove burner fire cover.
Background technology
At present, existing stove burner fire cover, general only offers one group of fire output hole or a groove that fires at fire cover face or sidewall, and it is simple in structure, but due to the limited amount of one group of fire output hole, in use, be easy to cause mix with air abundant not.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable for structure, can fully mix the improved stove burner fire cover of sufficient combustion with air.
The utility model solves the technical scheme that its technical problem adopts:
Improved stove burner fire cover, comprise the fire cover body being arranged on burner, in fire cover body, offer annular air cavity, fire cover body sidewall is tilting by circumferencial direction and offers a plurality of outer shroud fire holes, outer shroud fire hole communicates with annular air cavity, it is characterized in that, the fire cover body sidewall of described outer shroud fire hole top offers annular groove, on annular groove, being tilting offers a plurality of ，Zeng Yan hole, increasing flame hole and outer shroud fire holes that communicate with annular air cavity and forms mutually angle α.
Adopt the stove burner fire cover of this structure, by set up annular groove above outer ring fire hole, annular groove is provided with increasing ，Zeng Yan hole, flame hole and outer shroud fire hole jets out flames jointly, forms stronger combustion flame, and combustion gas is fully contacted with air, improves efficiency of combustion.
The utility model can also adopt following technical measures to solve:
Described angle α is acute angle; Form certain injection power, improve efficiency of combustion.
The aperture in described each increasing flame hole is less than the aperture of outer shroud fire hole; Fire hole is less, and jet velocity is faster, contacts sooner with air, burns more abundant.
Described annular groove is provided with annular bottom surface and annular top surface, and increasing flame hole is tilting and is opened on annular bottom surface; Increase flame hole and annular groove and form certain angle of inclination, flame is first to rush at after annular top surface, then along annular groove ejection, makes flame be unlikely to directly to spray and scatter, and has guaranteed the cohesion of firepower.
The beneficial effects of the utility model are:
The improved stove burner fire cover of the utility model, by set up annular groove above outer ring fire hole, annular groove is provided with and increases flame hole, increasing flame hole and outer shroud fire hole jets out flames jointly, form stronger combustion flame, combustion gas is fully contacted with air, improve efficiency of combustion.
Accompanying drawing explanation
Fig. 1 is that in the utility model, fire cover is arranged on the structural representation on burner.
Fig. 2 is the structural representation after the utility model dissects.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the structural representation after the utility model dissects.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 1 to 4, improved stove burner fire cover, comprise the fire cover body 1 being arranged on burner 6, in fire cover body 1, offer annular air cavity 2, fire cover body 1 sidewall is tilting by circumferencial direction and offers a plurality of outer shroud fire holes 3, outer shroud fire hole 3 communicates with annular air cavity 2, it is characterized in that, fire cover body 1 sidewall of described outer shroud fire hole 3 tops offers annular groove 4, on annular groove 4, be tilting and offer a plurality of increasing flame holes 5 that communicate with annular air cavity 2, increase flame hole 5 and form mutually angle α with outer shroud fire hole 3.
Adopt the stove burner fire cover 1 of this structure, by set up annular groove 4 above outer ring fire hole 3, annular groove 4 is provided with and increases flame hole 5, increasing flame hole 5 jets out flames jointly with outer shroud fire hole 3, form stronger combustion flame, combustion gas is fully contacted with air, improve efficiency of combustion.
More specifically embodiment as the present embodiment:
Described angle α is acute angle; Form certain injection power, improve efficiency of combustion.
The aperture in described each increasing flame hole 5 is less than the aperture of outer shroud fire hole 3; Fire hole is less, and jet velocity is faster, contacts sooner with air, burns more abundant.
Described annular groove 4 is provided with annular bottom surface 401 and annular top surface 402, and increasing flame hole 5 is tilting and is opened on annular bottom surface 401; Increase flame hole 5 and form certain angle of inclination with annular groove 4, flame is first to rush at after annular top surface 402, then along annular groove 4 ejections, makes flame be unlikely to directly to spray and scatter, and has guaranteed the cohesion of firepower.
Above-described specific embodiment, is only the utility model preferred embodiment, and the equivalent arrangements of such as doing according to the utility model claim, all should be technology of the present utility model and contain.
