Accompanying drawing acceptance of the bid keep the score state as follows: 1---outer cover; 2---flame boundling circle; 3---the inner bag air register; 4---the combustion chamber; 5---the water conservancy diversion blast cap; 6---nozzle; 7---kitchen range core gasifier; 8---discharging opening; 9---the air inlet port; 10---long tube pin type choke valve; 11---charging aperture; 12---the regulation and control handle; 13---thimble.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, the combustion chamber 4 of this burner is the space that is surrounded by inner bag air register 3 and flame boundling circle 2, outer cover 1 upper opening is wrapped in outside inner bag air register 3 and the flame boundling circle 2, upwardly opening in abutting connection with seam between outer cover 1 upper opening inwall and inner bag air register 3 and flame boundling circle 2 external wall of upper portion, we are referred to as " Bao Tian ".In the prior art outer cover is placed under inner bag and the boundling circle, we are referred to as " day bag ground ", the adjacency seam of it bag ground structure is to open downwards, therefore the High Temperature Gas cognition in the burner is stitched thus and is spilt downwards, the high-temperature gas that spills will be to the burner lower heating, also choke valve is heated, thereby aggravated the rough burning described in the background technology, make the arcing phenomenon more become serious.Wrap day structure of the present utility modelly and then solved this problem, its hot gas all makes progress, and has made full use of the energy first, second the substructure of entail dangers to burner not.As shown in Figure 1, kitchen range core gasifier 7 is arranged on the bottom of inner bag air register 3, its ejiction opening 6 is positioned at the lower central of combustion chamber 4, be covered with a water conservancy diversion blast cap 5 on the top of ejiction opening 6, blast cap 5 peripheries are provided with a plurality of flow deflectors, through hole is arranged between flow deflector, and from then on fuel enter combustion chamber 4 in the through hole mixes with air and burns.Combustion air is entered by the air inlet port 9 of outer cover 1 bottom, and the through hole on inner bag air register 3 enters combustion chamber 4 and burns with fuel mix.

The front end of long tube pin type choke valve 10 links to each other with kitchen range core gasifier 7, and its discharging opening 8 stretches in the gasification cavity of kitchen range core gasifier 7.The background technology part has been mentioned also has one section connecting pipe between choke valve of the prior art and the burner, when the gas phase light hydrocarbon fuel combustion, this section tube connector is also not too serious to the influence of burning, but when the liquid phase light hydrocarbon fuel combustion, the fuel in choke valve exit often gasifies in tube connector prematurely because of temperature rise and pressure drop, and cause local vapour lock and produce rough burning, be i.e. " arcing " often said.The applicant thinks that the reason that causes this arcing just is the out of turn of fuel gasification, just as if hurdler before the hurdle frame several meters just carried out the action of hurdling, and can stride on no hurdle, this place, do not go out, may be obstructed so this sportsman strides when facing the hurdle frame on the contrary.Arcing phenomenon of the prior art is actually the liquid phase light-hydrocarbon fuel in case spray when entering in the tube connector from choke valve, because volume enlarges and gasification has just taken place pressure drop, a large amount of gas savings have just produced vapour lock in tube connector, make fuel oil can't enter in the chamber of gasifier unobstructedly, can make burn-out suddenly in the burner, but because the fuel oil of carrying has pressure, it may so just cause ceaselessly arcing of burner in next detonation suddenly constantly again.Choke valve 10 of the present utility model directly links to each other its discharging opening 8 with kitchen range core gasifier 7, the liquid phase light-hydrocarbon fuel that is come out by discharging opening 8 directly enters in the gasification chamber of expansion of kitchen range core gasifier 7.After burner is enabled, kitchen range core gasifier 7 is heated by the kitchen range temperature, its temperature is much higher than light-hydrocarbon fuel oil gasification temperature, add that the liquid phase light-hydrocarbon fuel enters in the gasification chamber, because volume enlarges and pressure drop, gasification has taken place in fuel therein in time sharp, sprays into through hole on water conservancy diversion blast cap 5 by spout 6 and enters the combustion chamber and fully mix with air, and fuel smooth combustion produces heat energy for cooking use.Here, fuel stably gasifies timely once, burns, and can not produce air-resistance phenomenon.

The utility model can be used for two kinds of fuel of oil gas.As everyone knows, burning gas is that all burners do not have big problem, difficult gasification problem when being exactly oil firing.The utility model has solved this difficult problem, is a kind of burner of real oil-gas two-way.
