[0024] Example 1

[0025] like Figures 1 to 5As shown, an adjustable air intake combustion device includes an inner flame cap 1, an outer flame cap 2, a burner head 3, and a flame cap base 4. The inner flame cap 1 is inserted into the outer flame cap 2, and the flame cap base 4 is fitted onto the bottom of the outer flame cap 2. The flame cap base 4 is connected to the burner head 3 via an air regulating component 6. The flame cap base 4 is provided with multiple air intake channels 5, which are evenly distributed circumferentially on the flame cap base 4. The air regulating component 6 adjusts the air intake volume of the air intake channels 5. By adjusting the air intake area of ​​the air intake channels 5, the air regulating component 6 controls the amount of air entering the outer flame cap 2, thereby improving combustion efficiency.

[0026] The air regulating assembly 6 includes an air regulating ring 11, a motor 12, and a gear disk 13. The air regulating ring 11 has driven teeth 14, and the gear disk 13 has driving teeth 15. The air regulating ring 11 meshes with the gear disk 13. The gear disk 13 is connected to the moving end of the motor 12. After the motor 12 starts, it drives the gear disk 13 to rotate. The gear disk 13 drives the air regulating ring 11 to rotate through the driving teeth 15, changing the fit between the air regulating ring 11 and the burner cap base 4, thereby changing the air intake area of ​​the air intake channel 5 and achieving the purpose of controlling the air intake volume. The rotation angle of the motor 12 is controlled by detecting the air intake volume and the temperature detected by the thermocouple. By controlling the rotation angle of the motor 12, the air intake area of ​​the air intake channel 5 is controlled, thereby controlling the air intake volume.

[0027] Each of the air intake channels 5 has an air inlet 21 and an air outlet 22 at both ends. The air inlet 21 is located on the outside of the air intake channel 5, and the air outlet 22 is located on the top of the air intake channel 5. The air regulating ring 11 has multiple vent holes 23, the number of which corresponds one-to-one with the number of air inlets 21, and the vent holes 23 are connected to the air inlets 21. The outer burner cap 2 has combustion holes 24 and vent holes 25, and the vent holes 25 are connected to the air outlet 22. Air enters the air inlet 21 through the vent holes 23, then enters the air intake channel 5 through the air inlet 21, and finally reaches the air outlet 22 through the air intake channel 5, and then enters the outer burner cap 2 from the air outlet 22. After the air regulating ring 11 is rotated by the motor 12, the vent holes 23 will shift, changing the communication area between the vent holes 23 and the air inlets 21, thereby controlling the air intake and improving combustion efficiency.

[0028] The burner head 3 is connected to the outer flame cap 2 via an air intake pipe. The top of the outer flame cap 2 is provided with multiple support frames 26, which are evenly distributed axially on the outer flame cap 2. An inclined plate 27 is provided between adjacent support frames 26, and the combustion holes 24 are evenly distributed on the support frames 26 and the inclined plates 27. The through-hole direction of the combustion holes 24 on the inclined plates 27 is perpendicular to the inclined plates 27, and the combustion holes 24 on the inclined plates 27 are inclined inwards, allowing the combustion gas to reach the inner flame cap 1 more fully, improving combustion efficiency. The support frames 26 are A-shaped, and the vent holes 25 are located on the support frames 26.
