[0026] Reference Figure 1-8 A drainage cooling structure of a burner includes a drainage cooling component 1 and a sleeve 2. The drainage cooling component 1 is installed at the upper end of the sleeve 2. The ignition device 7 is sleeved inside the drainage cooling component 1 and the sleeve 2. A ventilation duct 94 is formed between the sleeve 2 and the ignition device 7. The lower end of the sleeve 2 is provided with an air inlet 22 communicating with the ventilation duct 94. The drainage cooling component 1 is provided with an air outlet 11 communicating with the ventilation duct. The air inlet 22 is communicated with the lower air chamber 91. The bottom of the lower air chamber 91 is provided with an air inlet 9 and a gas inlet 8. A lower partition 51 is provided at the upper part of the lower air chamber 91. A mixed gas port 95 is provided on the lower partition 51. The lower air chamber 91 is communicated with the upper air chamber 93 through the mixed gas port 95.

[0027] An annular partition 62 is disposed between the lower baffle 51 and the bottom of the lower air chamber 91. The annular partition 62 surrounds the sleeve 2 and is provided with an air inlet passage 96 on one side. One end of the annular partition 62 is connected to one end of the longitudinal partition 61, while the other end of the longitudinal partition 61 extends outward and is sealed to the outer shell of the lower air chamber 91. The air inlet 9 is located on one side near the air inlet passage 96 and near the longitudinal partition 61. The mixing port 95 is located on the other side away from the air inlet passage 96 and near the longitudinal partition 61. The gas inlet 8 is located in the passage between the air inlet 9 and the mixing port 95. The annular partition 62 and the longitudinal partition 61 both isolate air from gas, allowing only air to enter the ventilation duct 94. They also lengthen the horizontal distance between the air and gas passages, allowing the air and gas to mix evenly within the passages.

[0028] An upper baffle 41 is disposed above the lower baffle 51, forming a middle air chamber 92 between the two. A lower spacer sleeve 52 is vertically disposed above the lower baffle 51, and an upper spacer sleeve 42 is disposed above the upper baffle 41. The diameter of the upper spacer sleeve 42 is smaller than that of the lower spacer sleeve 52, and the top of the lower spacer sleeve 52 is higher than the bottom of the upper spacer sleeve 42. The interior of the upper spacer sleeve 42 communicates with the upper air chamber 93. A sleeve 2 extends through the bottom bowl 31, upper air chamber 93, and middle air chamber 92 at the bottom of the combustion chamber 97. The bottom of the sleeve 2 connects to the bottom of the lower air chamber 91. A drain inlet 12 is disposed at the bottom of the lower air chamber 91 and communicates with the ventilation duct 94. A middle gas chamber 92 is provided, and the mixed gas in the lower gas chamber 91 enters the middle gas chamber 92 through the mixed gas port 95. The mixed gas continues to mix as it flows through this channel, and the air and fuel gas are mixed more evenly, making the combustion more complete and reducing the carbon monoxide content after combustion. Finally, the mixed gas enters the upper gas chamber 93, passes through the outside of the ignition divider 32, passes through the ignition divider 32, and enters the combustion chamber 97.

[0029] The drainage and cooling component 1 is arranged in a ring shape, and the air outlet 11 is vertically arranged around the drainage and cooling component 1. A drainage outlet 10 is arranged at the lower end of the outer side of the drainage and cooling component 1, and a ring groove 13 is arranged on the outer side of the lower end of the drainage and cooling component 1. The ring groove 13 is embedded in the top end of the sleeve 2, and a flange 21 is arranged at the top end of the sleeve 2. The ring groove 13 is arranged on the upper part of the flange 21, and the lower end of the flange is placed at the bottom of the combustion chamber 97.

[0030] like Figure 2 、 Figure 3 The housing includes an upper shell 4 and a lower shell 5. The upper shells 4 and 5 are sealed together. The upper partition 41 is fixed to the bottom of the upper shell 4, and the lower partition 51 is fixed to the upper part of the lower shell 5. The upper shell 4 and the lower shell 5 are designed to be split, and can be replaced at will during maintenance. The upper shell and the lower shell can also be designed as an integrated structure as needed (such as Figure 4 、 Figure 5 ).

[0031] Ventilation, cooling and combustion-supporting process: air enters the lower air chamber 91, and part of the air directly enters the ventilation duct 94 from the air inlet holes 22 around the ignition device 7, first reducing the temperature of the lower part of the ignition device 7, and the air is ejected upward from the air outlet 11 on the drainage and cooling component 1, reducing the temperature of the head of the ignition device 7 and increasing the oxygen content in the combustion chamber 97, thereby achieving the effect of supporting combustion and reducing the content of carbon monoxide after combustion.

[0032] Drainage process: Liquid flows into the combustion chamber 97, then flows into the ventilation duct 94 through the drainage inlet 12, and flows out through the bottom drainage outlet 10. The size and number of the air inlet holes 22 and the space size of the ventilation duct 94 can be set as needed to ensure that the drainage effect is not affected during ventilation and cooling.

[0033] The structures and connections not mentioned are common knowledge.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
