Description

Technical Field

[0001] This utility model relates to the technical field of gas equipment, specifically to a novel burner head. Background Technology

[0002] The burner head generally has a flame distribution chamber. After the gas enters the flame distribution chamber from the gas inlet channel, it diffuses in the flame distribution chamber and is ejected outward to burn and form a flame. The existing burner head flame distribution chamber generally ejects gas outward through multiple flame outlets set on the burner cap. Since the distribution of the flame outlets is not continuous, the flame output effect of the burner cap is relatively concentrated and not uniform.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of burner head. By setting a connecting block, a gas outlet groove can be formed on the burner head. The fire distribution chamber sprays gas evenly outward through the gas outlet groove, thereby making the flame output effect of the burner head more uniform. At the same time, there is no need to open multiple additional flame outlet holes on the burner head, which simplifies the structure of the burner head and makes the burner head more aesthetically pleasing.

[0005] The purpose of this utility model is achieved as follows:

[0006] A novel burner head includes a flame distribution base and a flame cover. The flame distribution base and the flame cover are connected to form a flame distribution chamber. The flame cover includes a bottom ring part and a top shell part. A connecting block is provided between the bottom ring part and the top shell part. The connecting block is connected and fixed to the bottom ring part and the top shell part respectively, so that a gas outlet groove distributed in a circumferential direction is formed between the bottom ring part and the top shell part.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See Figures 1-9 This novel burner head includes a flame distribution base 1 and a flame cover 2. The flame distribution base 1 and the flame cover 2 are connected to form a flame distribution chamber. The flame cover 2 includes a bottom ring portion 21 and a surface shell portion 22. A connecting block 23 is provided between the bottom ring portion 21 and the surface shell portion 22. The connecting block 23 is connected and fixed to the bottom ring portion 21 and the surface shell portion 22 respectively, so that a gas outlet groove 24 distributed circumferentially is formed between the bottom ring portion 21 and the surface shell portion 22. The gas outlet groove 24 communicates with the flame distribution chamber. By setting the connecting block 23, the gas outlet groove 24 can be formed on the flame cover 2. The flame distribution chamber sprays gas evenly outward through the gas outlet groove 24, so that the flame output effect of the flame cover 2 is more uniform. At the same time, there is no need to open multiple additional flame outlet holes on the flame cover 2, which simplifies the structure of the flame cover 2 and makes the flame cover 2 more aesthetically pleasing.

[0029] Furthermore, a plurality of connecting blocks 23 are provided between the bottom ring portion 21 and the surface shell portion 22. The connecting blocks 23 are evenly distributed along the circumference, which further improves the stability of the connection structure between the bottom ring portion 21 and the surface shell portion 22.

[0030] Furthermore, the shell portion 22 is provided with a thickened portion 221 at the position corresponding to the connecting block 23. The thickened portion 221 protrudes outward from the shell. The thickened portion 221 can improve the structural strength of the shell portion 22. At the same time, the thickened portion 221 can also be used to support the support block 41 on the furnace frame 4.

[0031] Furthermore, such as Figure 5 , Figure 6 As shown, there are eight thickened parts 221, which are evenly distributed around the center of the shell part 22 in the circumferential direction. They can be adapted to most types of furnace racks 4 on the market. The support blocks 41 of the mainstream furnace racks 4 on the market are generally four. The cross formed by the four support blocks 41 and the center line can be a positive cross or an inclined cross at 45°. The eight thickened parts 221 are evenly arranged on the shell part 22, which can basically adapt to the mainstream furnace racks 4.

[0032] Furthermore, the connecting block 23, the face shell 22, and the bottom ring 21 are integrally formed, giving the flame cap 2 better overall structural strength.

[0033] Furthermore, the inner side of the faceplate 22 is provided with a plurality of stud connection parts 222, and the ignition seat 1 is provided with screw holes 16 corresponding to the stud connection parts 222. The stud connection parts 222 and the screw holes 16 are connected and engaged by screws to install and fix the ignition seat 1 and the ignition cap 2, so that the connection strength between the ignition cap 2 and the ignition seat 1 is better and it is not easy to shift.

[0034] Furthermore, a flow divider 3 is provided in the flame distribution chamber at the position between the flame distribution seat 1 and the flame cap 2. The flow divider 3 is annular in shape. The flame distribution chamber forms an upper mixed layer 11 and a lower mixed layer 12 distributed sequentially from top to bottom through the flow divider 3. The flame distribution seat 1 has an air inlet 13. The flow divider 3 is tightly connected to the side of the flame distribution chamber away from the air inlet 13. The flow divider 3 and the side of the flame distribution chamber near the air inlet 13 form an air guiding channel 14. The bottom of the flow divider 3 forms a first guide surface 31 that can guide the airflow from the side of the flame distribution chamber away from the air inlet 13 to the side near the air inlet 13. The first guide surface 31 has a continuous planar structure without perforations or hollow areas.

[0035] When the gas enters the lower mixing layer 12 from the inlet 13, under the action of the diverter 3, the gas will not directly pass through the diverter 3 to enter the upper mixing layer 11. The gas needs to form a detour path under the action of the first guide surface 31. Therefore, the gas can diffuse fully before entering the upper mixing layer 11 through the guide channel 14. The diverter 3 enables the gas flow to detour in the lower mixing layer 12 before entering the upper mixing layer 11 through the guide channel 14, thereby making the gas distribution in the upper mixing layer 11 more uniform and achieving a better flame equalization effect.

[0036] Meanwhile, due to the presence of the diversion component 3, the volume of the upper mixing layer 11 is inevitably smaller than the overall volume of the gas distribution chamber, resulting in a relatively increased internal pressure in the upper mixing layer 11. Consequently, the chance of flashback of the external flame will be relatively reduced.

[0037] Furthermore, the ignition base 1 is provided with a supporting step 17, the lower side of the diverter 3 abuts against the supporting step 17, the bottom of the connecting block 23 abuts against the upper side of the diverter 3, and the stud connection 222 abuts against the side of the diverter 3 facing the guide gas channel 14. The supporting step 17, the connecting block 23 and the stud connection 222 form a limiting structure for limiting the position of the diverter 3, which further improves the stability of the connection structure between the diverter 3 and the ignition base 1 and the burner cap 2.

[0038] Furthermore, the flow divider 3 is provided with a second flow guide surface 32 on one side of the gas guide channel 14, which can guide the airflow from the lower mixing layer 12 upward into the upper mixing layer 11. The second flow guide surface 32 has a continuous planar structure without perforations or hollow areas. The second flow guide surface 32 gives the flow divider 3 a certain thickness, increases the distance of the gas flow through the gas guide channel 14, and makes the gas diffusion more complete.

[0039] Furthermore, the diverter 3 is in the shape of a closed ring, ensuring that all the gas in the lower mixing layer 12 must pass through the gas guide channel 14 before entering the upper mixing layer 11, so that the gas can diffuse better in the lower mixing layer 12 before entering the upper mixing layer 11, thereby making the gas distribution in the upper mixing layer 11 more uniform.

[0040] The flow area of ​​the air guide channel 14 is greater than or equal to the flow area of ​​the air inlet 13, which optimizes the volume of the upper mixing layer 11, thereby further reducing the chance of backfire from the external flame.

[0041] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
