A kind of burner of gas-cooker
Technical field
The utility model relates to a kind of burner of gas-cooker.
Background technology
Usually the burner of gas-cooker comprises burner, big fire cover base, big fire lid and little fire lid, wherein is provided with the swingfire that the is obliquely installed groove that fires at the big fire tops, behind the combustion gas mixing air through swingfire fire groove ejection rotation and burning.The phenomenon of incomplete combustion appears in this swingfire mode easily, and carbon monoxide content is higher in the discharging, influences safe in utilization.
Summary of the invention
The purpose of the utility model provides the burner of more even, the safe and reliable gas-cooker of a kind of combustion flame.
The technical solution of the utility model is: a kind of burner of gas-cooker, and comprise fiery cover base, be provided with the fire big fire lid of groove of swingfire, on the periphery wall of said big fire lid, be provided with circular straight fiery fire output hole.
Be provided with straight fiery fire output hole at big fire lid periphery, combustion gas not only can spray through the swingfire groove rotation that fires like this, can also form straight flame in the periphery, and integral combustion is more even, and inside and outside flame combustion is more efficient, and is safe and reliable.
On said fiery cover base, be provided with four sections fan-shaped air vents of symmetry.Can further improve the air capacity that gets into burner, satisfy burning and supply with, improve efficiency of combustion with oxygen.
The utility model has the advantages that: it is more even to burn, and inside and outside flame combustion is more efficient, and is safe and reliable.

The specific embodiment
Embodiment:
Consult Fig. 1-2, a kind of burner of gas-cooker comprises fiery cover base 1, is provided with swingfire fire the big fire lid 2 and the little fire lid 3 of groove 4, on the periphery wall of big fire lid 2, is provided with circular straight fiery fire output hole 5.On fiery cover base 1, be provided with four sections fan-shaped air vents 6 of symmetry.
In the present embodiment, the fire output hole of big fire lid is the direct rotary integral type, and the angle difference that fires of two fire output holes realizes that internal flame gathers, and flame envelope is tangent not overlapping, and the thermal efficiency is higher.Four air vents on the fire cover base can increase by 30% air feeding amount, make burning more abundant.
Above-listed detailed description is specifying to one of the utility model possible embodiments; This embodiment is not the claim in order to restriction the utility model; Allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
