Description
Technical field
The utility model relates to a kind of gas burner, particularly relates to a kind of gas burner improving gas mixed nub structure.
Background technology
At present, the blowing type gas burner on market in use, there will be because air blast lost efficacy, flow out along the pipeline of air blast, and cause poisoning phenomenon, there is larger potential safety hazard by combustion gas.Simultaneously, in order to control combustion better flame and improve efficiency of combustion, air door is provided with in the guide duct of burner, but when damper positions slightly changes, significant change can be there is in the air inflow of guide duct at once, make gaseous mixture proportional imbalance, cause the phenomenon occurring flame instability or flare drift, affect efficiency of combustion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of gas burner improving gas mixed nub structure.
The utility model solves the technical scheme that its technical problem adopts:
A kind of gas burner improving gas mixed nub structure, comprise body of heater and gas mixing pipe, described gas mixing pipe one end is communicated with described body of heater, the other end is air inlet, described gas mixing pipe sidewall is provided with several fuel gas holes obliquely, and described gas mixing pipe is outside equipped with the interlayer air chamber that described fuel gas hole is wrapped to form sealing by shell, described shell offers the air inlet of describedization air chamber, described air inlet below described fuel gas hole is provided with wind deflector, described wind deflector offers several air-guiding holes.
Described fuel gas hole annular spread is in the sidewall of described gas mixing pipe, and correspondingly, described shell annular is arranged on the sidewall of described gas mixing pipe, forms annularization air chamber.
Described air-guiding hole is be evenly distributed in the inclined hole on described wind deflector.
Described body of heater top is provided with banking fire lid, and described banking fire covers and is provided with logical fire hole and is uniformly distributed in banking fire lid periphery but not center.
The beneficial effects of the utility model are: the utility model passes through said structure, when combustion gas is from entering into of air inlet air chamber, under the damping effect changing gas chamber sidewall, combustion gas can spray in gas mixing pipe obliquely along fuel gas hole, in mixing tube, form negative pressure, even if air blast lost efficacy, air also can flow in gas mixing pipe and combustion gas mixing from the air inlet below fuel gas hole under the effect of negative pressure, the phenomenon preventing combustion gas from flowing out from air inlet, eliminates potential safety hazard; Simultaneously, air inlet below fuel gas hole is provided with wind deflector, wind deflector is provided with several air-guiding holes, like this, under the effect of wind deflector, when air door changes, the air flowing through air-guiding hole can not change at once, guarantee that air inflow is stablized, and then make the flameholding of burner, improve efficiency of combustion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of gas burner improving gas mixed nub structure, comprise body of heater 1 and gas mixing pipe 2, gas mixing pipe one end is communicated with body of heater 1, and the other end is air inlet 11, and gas mixing pipe 2 sidewall is provided with several fuel gas holes 4 obliquely, gas mixing pipe 2 is outside equipped with the interlayer air chamber 8 that fuel gas hole 4 is wrapped to form sealing by shell 3, the air inlet 5 of offering air chamber 8 on shell 3, air inlet 11 place below fuel gas hole 4 is provided with wind deflector 6, wind deflector 6 offers several air-guiding holes 7.
The utility model passes through said structure, when combustion gas is from air inlet 5 entering into air chamber 8, under the damping effect changing air chamber 8 sidewall, combustion gas can spray in gas mixing pipe 2 along fuel gas hole 4 obliquely, in mixing tube 2, form negative pressure, even if air blast lost efficacy, air also can flow in gas mixing pipe 2 and combustion gas mixing from the air inlet 11 below fuel gas hole 4 under the effect of negative pressure, the phenomenon preventing combustion gas from flowing out from air inlet 11, eliminates potential safety hazard; Simultaneously, air inlet 11 place below fuel gas hole 4 is provided with wind deflector 6, wind deflector 6 is provided with several air-guiding holes 7, like this, under the effect of wind deflector 6, when air door changes, the air flowing through air-guiding hole 7 can not change at once, guarantee that air inflow is stablized, and then make the flameholding of burner, improve efficiency of combustion.
As preferred embodiment of the present utility model, fuel gas hole 4 annular spread is in the sidewall of gas mixing pipe 2, and correspondingly, shell 3 annular is arranged on the sidewall of gas mixing pipe 2, forms annularization air chamber; The annular spread of fuel gas hole 4 makes combustion gas spray equably in gas mixing pipe 2, is conducive to combustion gas and fully mixes with air.
In the present embodiment, air-guiding hole 7 is for being evenly distributed in the inclined hole on wind deflector 6; After air flows through inclined hole, air can form swirling eddy in gas mixing pipe 2, is conducive to fully mixing of combustion gas and air equally.
In the present embodiment, body of heater 1 top is provided with banking fire lid 9, banking fire lid 9 is provided with logical fire hole 10 and is uniformly distributed in banking fire lid 9 periphery but not center; Make the air inlet 11 of gas mixing pipe 2 can not be formed directly through with logical fire hole 10, then mixed airflow can be locked in gas mixing pipe 2 by banking fire lid 9, can not produce power run off; And mixed airflow flows out equably from logical fire hole 10, combustion efficiency is good, the noise produced when can also reduce burning.
The utility model is safe and reliable, and flameholding, efficiency are high, noise is low, can be widely used among various gas furnace.
