[0031] Example 1

[0032] like Figure 1~Figure 4 As shown, the utility model discloses a combustion chamber, which includes a combustion chamber body 3, the interior of the combustion chamber body 3 is cylindrical, and an air inlet hole communicating with the interior of the combustion chamber body 3 is opened on the side wall of the combustion chamber body 3;

[0033] An air inlet pipe 1 is arranged in the combustion chamber body 3, and the air inlet pipe 1 includes an open end 11 and a sealed end; the open end 11 of the air inlet pipe 1 is connected to the air inlet hole; the sealed end of the air inlet pipe 1 is sealed by a sealing plate 10, and the sealing plate 10 is arranged obliquely so that its plate surface faces the inner wall of the combustion chamber body 3; an air outlet 4 is opened on the side wall of the air inlet pipe 1, and the air outlet 4 faces the inner wall of the combustion chamber body 3, and the air outlet 4 is located at the sealed end of the air inlet pipe 1, and is located on the lower side of the sealing plate 10.

[0034] In the above structure, since the sealing plate 10 at the sealing end of the air inlet pipe 1 is inclined, the air outlet 4 is located on the side, and the interior of the combustion chamber body 3 is cylindrical, that is, the inner wall is arc-shaped; when the wind enters the air inlet pipe 1 from the air inlet hole, the sealing plate 10 changes the direction of the wind, so that the wind is blown out from the air outlet 4 at an angle and blows toward the inner wall of the combustion chamber body 3 at an angle. Since the inner wall is arc-shaped, the wind can flow along the inner wall, and then the wind can rotate inside the combustion chamber body 3. Since the wind rotates inside the combustion chamber body 3, the liquid fuel in the combustion chamber can be fully atomized.

[0035] In the present invention, the axis of the air inlet pipe 1 passes through the center of the combustion chamber body 3 .

[0036] like Figure 1 As shown, the air inlet hole is opened at the top of the combustion chamber body 3, the air inlet pipe 1 is vertically arranged, and the axis of the air inlet pipe 1 passes through the center of the combustion chamber body 3. Figure 1 In the figure, the air inlet pipe 1 is vertically arranged, the lower end of the sealing plate 10 is located on the left, and the air outlet 4 is located on the left, then the wind coming out of the air outlet 4 blows toward the inner wall of the combustion chamber body 3 at an angle to the lower left; since the wind blows toward the inner wall of the combustion chamber body 3 at an angle to the lower left, most of the wind will flow counterclockwise along the arc-shaped inner wall, thereby causing the wind to rotate inside the combustion chamber body 3.

[0037] like Figure 1 As shown, in the present invention, the pipe opening at the sealing end is an oblique pipe opening, and the sealing plate 10 is sealed on the oblique pipe opening, so that one end of the sealing plate 10 is high and the other end is low.

[0038] Furthermore, the distance from the lowest end of the sealing plate 10 to the inner wall of the combustion chamber body 3 is less than or equal to the radius of the combustion chamber. Figure 1 As shown, the air inlet pipe can be located in the upper half of the combustion chamber body 3, ensuring that the wind blows downward at an angle, thereby ensuring that most of the wind can rotate counterclockwise, thereby causing the wind to rotate inside the combustion chamber body 3.

[0039] Furthermore, the interior of the combustion chamber body 3 is in a through cylindrical shape, and a fire baffle 7 is provided at one end of the combustion chamber body 3. A fire outlet hole 8 is provided at the center of the fire baffle 7, and the diameter of the fire outlet hole 8 is smaller than the inner diameter of the combustion chamber body;

[0040] Or a plurality of fire baffles 7 are arranged at one end of the combustion chamber body 3, the fire baffles 7 are arranged in parallel and spaced apart, a fire outlet hole 8 is opened in the center of the fire baffle 7, and the diameter of the fire outlet hole 8 is smaller than the inner diameter of the combustion chamber body.

[0041] like Figure 2 , 4 As shown, the fire baffle 7 is located at the right end. When the combustion chamber is applied to the combustion mechanism, a fan 9 is arranged at the left end of the combustion chamber to introduce air to ensure combustion, and at the same time, the flame and fuel in the combustion chamber move along the axis direction of the combustion chamber. Due to the existence of the fire baffle 7, liquid fuel can be prevented from leaking out of the combustion chamber.

[0042] When multiple fire baffles 7 are provided, the intervals between the multiple fire baffles 7 form a liquid collecting tank to prevent the liquid fuel from leaking out. At the same time, since the wind is rotating in the utility model, the liquid fuel in the liquid collecting tank can be atomized again under the action of the rotating wind to ensure sufficient combustion and avoid fuel waste.

[0043] Example 2

[0044] like Figure 1~Figure 4 The utility model also discloses a combustion mechanism, which includes an ignition element 5, a nozzle 6 and the combustion chamber in Example 1; the ignition element 5 is arranged in the combustion chamber body 3; a fuel hole 2 connected to the inside of the combustion chamber body 3 is opened on the side wall of the combustion chamber body, and the nozzle 6 is arranged at the fuel hole 2.

[0045] In the combustion mechanism of the present invention, since the sealing plate 10 at the sealing end of the air inlet pipe 1 is inclined, the air outlet 4 is located on the side, and the interior of the combustion chamber body 3 is cylindrical, that is, the inner wall is arc-shaped; when the wind enters the air inlet pipe 1 from the air inlet hole, the sealing plate 10 changes the direction of the wind, so that the wind is blown out from the air outlet 4 at an angle and blows toward the inner wall of the combustion chamber body 3 at an angle. Since the inner wall is arc-shaped, the wind can flow along the inner wall, and then the wind can rotate inside the combustion chamber body 3. Since the wind rotates inside the combustion chamber body 3, the liquid fuel in the combustion chamber can be fully atomized.

[0046] In the present invention, the outlet of the nozzle 6 is located at the fuel hole 2 .

[0047] The current ignition element 5 and the nozzle 6 are very close, and the nozzle 6 is located in the entire combustion chamber. Since the nozzle 6 is burned for a long time, carbon deposition is easy to occur at the nozzle 6, especially when the fuel quality is poor. If the nozzle 6 is set far away, ignition is difficult. In the present utility model, the outlet of the nozzle 6 is located at the fuel hole 2, which can prevent the nozzle 6 from being burned for a long time and carbon deposition. At the same time, there is a whirlwind in the combustion chamber, which can fully atomize the fuel, thus avoiding the problem of difficulty in ignition due to the long distance between the ignition element and the nozzle 6.

[0048] Furthermore, the ignition element 5 is located in the air inlet pipe 1 , an ignition end of the ignition element 5 passes through the sealing plate 10 and extends out of the air inlet pipe 1 , and the ignition element 5 is fixed on the sealing plate 10 .

[0049] like Figure 3 As shown, the axis of the ignition element 5 coincides with the axis of the air inlet pipe 1, and the inner diameter of the air inlet pipe 1 is larger than the diameter of the ignition element 5. The ignition element 5 can be an iridium spark plug.

[0050] Furthermore, the centers of the air inlet hole and the fuel hole 2 are located on the same circle, the axis of the fuel hole 2 passes through the center of the combustion chamber body 3, and the fuel hole 2 is located on the opposite side of the air outlet 4, so that the fuel hole 2 faces the outer plate surface of the sealing plate 10; the ignition end of the ignition element 5 is located at the center of the combustion chamber body 3.

[0051] like Figure 3 As shown, the fuel hole 2 is located on the opposite side of the air outlet 4, so that the fuel hole 2 faces the outer surface of the sealing plate 10. The outer surface of the sealing plate 10 can block the oil, so that the fuel is concentrated at the ignition end of the ignition element 5. At the same time, the sprayed fuel will also drive part of the wind to blow toward the outer surface of the sealing plate 10, and then the wind flows downward at the center of the combustion chamber, and then part of the wind rotates at the center, ensuring sufficient atomization of the fuel.

[0052] Further, such as Figure 4As shown, a blower 9 is provided at one end of the combustion chamber body 3 away from the fire baffle 7. The blower 9 can inject a large amount of air into the combustion chamber to ensure sufficient combustion inside the combustion chamber.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
