DETAILED DESCRIPTION

[0023] Figures 1 to 6 This is the best embodiment of the mixed combustion burner. Figures 1 to 6 The utility model is further described.

[0024] Reference Figure 1-2 The mixed combustion burner includes a burner base 1, an upper burner shell 2, a diverter ring 4, an oil receiving pan 13, an oil receiving pipe 10, a fire pipe 6 and a fire cover. The upper burner shell 2 is arranged on the upper side of the burner base 1, the fire cover is arranged on one side of the burner base 1, the fire pipe 6 is arranged on the inner side of the fire cover, the diverter ring 4 is arranged on the inner side of the upper burner shell 2, the oil receiving pipe 10 is spirally arranged in the burner base 1, and the spiral diameter of the oil receiving pipe 10 gradually increases from bottom to top, the oil receiving pan 13 is arranged between the oil receiving pipe 10 and the diverter ring 4, the upper end of the oil receiving pipe 10 is connected to the upper side of the oil receiving pan 13, and the lower end of the oil receiving pipe 10 is arranged through the burner base 1.

[0025] A burner bottom shell 8 is located inside the burner base 1, with the upper burner shell 2 positioned above it. An oil connection pipe 10 is located within the burner bottom shell 8. An air inlet connector 9 is threadedly connected to the center of the underside of the burner base 1. An annular step is provided at the top of the air inlet connector 9, which supports and secures the burner bottom shell 8. A mixture of gas and air enters the burner bottom shell 8 through the air inlet connector 9.

[0026] A spark holder 15 is fixedly provided on one side of the burner base 1. A spark outer cover is fixed on the upper side of the spark holder 15. A spark opening is provided on the upper end of the spark outer cover facing the upper burner shell 2. The upper end of the spark tube 6 passes through the spark holder 15 and extends into the spark outer cover. The upper end of the spark tube 6 is arranged opposite the spark opening. A spark inner cover 14 is also provided on the upper end of the spark tube 6. The side of the spark inner cover 14 has an opening facing the spark opening.

[0027] A slot 1501 is provided on the outer side of the upper portion of the fire starter seat 15, and a block 7 is provided at the lower end of the fire starter cover to fit into the slot 1501, so that the fire starter cover can be quickly disassembled and assembled, with a simple structure and easy installation.

[0028] The oil receiving pipe 10 has the same outer diameter as the diverter ring 4, allowing the gas-air mixture to reach the outside of the diverter ring 4 and then enter the upper burner shell 2 for full combustion. Several supports 12 are provided on the oil receiving pipe 10, connecting between adjacent pipe coils. These supports 12 prevent vibration caused by the gas-air mixture passing through the pipe, maintaining a stable structure.

[0029] See also Figure 3 In this embodiment, the diverter ring 4 includes a plurality of wavy rings 401 and horizontal washers 402, which are arranged alternately. The gas and air mixture enters the upper burner shell 2 through the gaps between the wavy rings 401 and the horizontal washers 402, where the gas and air are evenly mixed again, ensuring stable combustion of the main fire.

[0030] See also Figure 4 A through hole is formed in the middle of the oil receiving pan 13, and a horizontal pipe 11 is provided at the upper end of the oil receiving pipe 10. One end of the horizontal pipe 11 is bent upward and passes through the through hole, and the upwardly bent end of the horizontal pipe 11 is set higher than the bottom of the oil receiving pan 13. This prevents ash from falling into the oil receiving pipe 10 and causing blockage.

[0031] In addition, the oil connection pipe 10 in this embodiment is also connected to the air inlet pipeline through a valve. Back-blowing of the oil connection pipe 10 is achieved through the air inlet pipeline to prevent the oil connection pipe 10 from being blocked.

The two support clips 1201 are respectively arranged on both sides of the oil receiving pipe 10. The clamps at both ends of the support clip 1201 respectively snap on the two adjacent circles of the pipe body, and the middle parts of the two support clips 1201 are fixedly connected by screws.

[0033] The mixed combustion burner is provided with an oil receiving pipe 10 inside the burner base 1. The oil receiving pipe 10 is used to directly receive the oil in the oil receiving pan 13, reducing the cleaning workload. More importantly, the spiral structure of the oil receiving pipe 10 can fully mix the gas and air mixture entering the burner base 1, and has a certain spiral guide effect, so that the gas and air mixture can smoothly reach the diverter ring 4 while mixing. Compared with the previous diverter hole structure, the resistance is smaller and the mixing is more complete. In addition, the heat of the oil receiving pipe 10 can be used to preheat the gas and air mixture, and the combustion is more complete.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
