[0025] The specific implementation of the utility model will be further explained below in combination with the drawings:

[0026] As Figures 1-5 Indicated,

[0027] A new type furnace head for burner includes furnace head body 1, first air inlet pipe 2 and second air inlet pipe 3, first air inlet pipe 2 and second air inlet pipe 3 are connected on furnace head body 1 respectively, furnace head body 1 is communicated with first air inlet pipe 2 and second air inlet pipe 3 respectively, first air inlet pipe 2 and second air inlet pipe 3 are all integrally formed structure, furnace head body 1, first air inlet pipe 2 and second air inlet pipe 3 are all stainless steel material. In this embodiment, since first air inlet pipe 2 and second air inlet pipe 3 are all integrally formed structure, natural gas mixes with air sufficiently, so that gas is combusted sufficiently, and energy efficiency can be higher. Therefore, compared with traditional technology that adopts die-casting aluminum to manufacture and adopts glueing or riveting to connect furnace head body 1, the utility model will not appear gas leakage, thereby greatly improving the service life of furnace head.

[0028] As a preferred embodiment, first air inlet pipe 2 and furnace head body 1 and second air inlet pipe 3 and furnace head body 1 are all fixed by welding. It can be understood that first air inlet pipe 2 and second air inlet pipe 3 are welded at the connecting place with furnace head body 1, and gas leakage will not easily occur in long-term use. Traditional riveting or glueing will easily cause glue separation or gap cracking after use for a period of time, thereby causing leakage.

[0029] As a preferred embodiment, first air inlet pipe 2 and second air inlet pipe 3 are both arc-shaped and bent at the turning position. It can be understood that the traditional furnace head is generally provided with right-angle bending first air inlet pipe, so that the gas passage is not smooth, thereby reducing premixing effect or combustion efficiency.

[0030] As a preferred embodiment, the wall thickness of first air inlet pipe 2 and second air inlet pipe 3 is 0.8mm. The thin wall and stainless steel material make heat conduction slow and temperature drop fast, thereby effectively protecting the mounting glue part outside the furnace head, and prolonging the service life of the furnace head and other accessories.

[0031] As a preferred implementation, the gas outlet end of the first gas inlet pipe 2 extends to the inner top of the burner body 1. The first gas inlet pipe 2 is an inner ring gas outlet, and the second gas inlet pipe 3 is an outer ring gas outlet. In this way, the inner ring and the outer ring are separated, and the size of the burner can be adjusted.

[0032] As a preferred implementation, a gas mixing frame 4 is connected between the gas inlet end of the first gas inlet pipe 2 and the gas inlet end of the second gas inlet pipe 3. The gas mixing frame 4 is provided with a pair of gas inlet holes, each of which corresponds to the first gas inlet pipe 2 and the second gas inlet pipe 3, respectively. The gas inlet holes include a liquefied gas hole 5 and an air hole 6. By providing the gas mixing frame 4, the liquefied gas and air can be easily introduced. The liquefied gas hole 5 is connected to the liquefied gas pipeline, and the air hole 6 is connected to the air pipeline, making the installation compact and convenient to use.

[0033] As a preferred implementation, the liquefied gas hole 5 is circularly arranged, and the air hole 6 is arcuately arranged on both ends or the outer side of the liquefied gas hole 5. In this way, the pre-mixing effect of the liquefied gas and air is better, and the air surrounds the liquefied gas, which can be better mixed into the air.

[0034] As a preferred implementation, a fixing frame 7 is welded to the top outer wall of the burner body 1. This facilitates the installation of the external components.

[0035] As a preferred implementation, a connecting frame 8 is welded to the bottom surface of the burner body 1. This facilitates the installation of the external components.

[0036] As a preferred implementation, a reinforcing rib 9 is welded between the first gas inlet pipe 2 and the second gas inlet pipe 3. It can be understood that the installation strength of the first gas inlet pipe 2 and the second gas inlet pipe 3 can be enhanced, and the first gas inlet pipe 2 and the second gas inlet pipe 3 can be firmly installed on the external components, improving the quality of use.

[0037] As a preferred implementation, a fireproofing element 10 is welded between the top surface of the fixing frame 7 and the burner body 1.

[0038] In the present application, the gas inlet holes on the first gas inlet pipe 2 and the second gas inlet pipe 3 are of the same structure. The first gas inlet pipe 2 is an inner ring gas outlet (burning), and the second gas inlet pipe 3 is an outer ring gas outlet (burning). The liquefied gas enters the interior of the first gas inlet pipe 2 (the second gas inlet pipe 3) through the liquefied gas hole 5, and the air enters the interior of the first gas inlet pipe 2 (the second gas inlet pipe 3) through the air hole 6. Then, pre-mixing is achieved in the interior of the first gas inlet pipe 2 (the second gas inlet pipe 3), and then the gas is discharged from the gas outlet end of the first gas inlet pipe 2 (the second gas inlet pipe 3).

[0039] It should be pointed out that the main problem existing in the prior art is that in the prior art, the furnace head body and the air inlet pipe are generally made by die casting aluminum integrated molding, however, riveting connection or glue connection is needed between the furnace head body and the air inlet pipe, which is easy to cause gas leakage in use, thereby greatly reducing the use quality of the burner furnace head.

[0040] Therefore, through the improvement of the present application, the furnace head body 1, the first air inlet pipe 2 and the second air inlet pipe 3 are all made of stainless steel material, and the first air inlet pipe 2 and the second air inlet pipe 3 are both integrated molding structure, and the connection between the furnace head body 1 is welded, which will not cause gas leakage in long-term use, thereby greatly improving the service life of the furnace head; in addition, the first air inlet pipe 2 and the second air inlet pipe 3 are both arc-shaped and bent at the turning position, and the thickness is 0.8mm, which is thin-walled and made of stainless steel material, so that the heat conduction is slow and the cooling is fast, thereby effectively protecting the installation glue parts outside the furnace head, prolonging the service life of the furnace head; at the same time, the stainless steel material is also corrosion-resistant and high-temperature-resistant, the inner wall is smooth, the turning position is arc-shaped and bent, so that the air passage is smooth, the premixing effect is good and the premixing efficiency is high, so that the combustion is more sufficient.

[0041] The above embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application, and various deformations and improvements of the technical solutions of the present application made by ordinary engineering technical personnel without departing from the design spirit of the present application should fall within the protection scope determined by the claims of the present application.
