Description

Technical Field

[0001] This utility model relates to the field of stove head technology, and in particular to a swirl-fired stove head. Background Technology

[0002] Existing fuel-fired electric injection burners and gas-push burners have many shortcomings, such as: 1. Pressure atomization is achieved by direct blowing with a fan, resulting in incomplete combustion and fuel waste. 2. They cannot achieve a low flame; high oil pressure and strong airflow result in a large flame, while low airflow and low oil pressure cause oil to fall and fail to burn properly. 3. The existing burner's matching oil pump, controller, and other electronic components have a high failure rate, leading to wasted time and money on maintenance. Therefore, there is an urgent need for a swirl burner that achieves 100% gasification, complete combustion, adjustable flame size, and saves both fuel and electricity. Summary of the Invention

[0003] The purpose of this invention is to provide a swirl-fired burner head that achieves complete gasification, thereby overcoming the problem that existing burner heads cannot operate at low flames. It features the characteristics of not requiring electric heating, relying on its own heat for vaporization and combustion, and saving electricity and oil.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a swirl-fired burner head, including a vaporization chamber, a vaporization plate, an oil bowl, a centrifugal shaft, an ignition needle, an atomizing oil pipe, a wind duct, a main air outlet, a fire cage ring, a fan motor, a motor impeller, and a fan housing. The fire cage ring and the oil bowl are stepped, as are the oil bowl and the wind duct. The vaporization chamber is located at the top of the centrifugal shaft. The vaporization plate and the vaporization chamber are welded at four protruding points, and there is a 3 mm gap between the vaporization chamber and the vaporization plate. An air inlet plate is provided on the lower side of the vaporization chamber, and the inlet of the main oil inlet pipe is provided above the vaporization plate. The inlet of the atomizing oil pipe is connected to the air inlet plate, and an air duct is provided above the motor impeller.

[0006] Preferably, the vaporization chamber and the centrifugal shaft are fixed with screws.

[0007] Preferably, the vaporization chamber is concave-convex in shape.

[0008] Preferably, the main oil inlet pipe and the air duct are welded at their junction, and the ignition needle and the air duct are connected in a cross shape and fixed with screws.

[0009] Preferably, the atomizing oil pipe and the air duct are welded together, and the air inlet plate and the air duct are welded together at the junction.

[0010] Preferably, the fan motor and the motor impeller are rigidly connected.

[0011] Preferably, a main air outlet is provided on the side of the air duct.

[0012] Preferably, a wind-oil linkage valve is provided next to the main air outlet to achieve wind-oil matching.

[0013] Preferably, the air duct and the fan housing are connected by a flange.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model's swirl-fired burner head uses a rotating fan to blow air and drive the internal vaporizer to rotate. High-pressure ignition and combustion for three to ten seconds ensure complete vaporization of the oil in the vaporization chamber, achieving 100% vaporization combustion, high oil utilization, and energy saving. 2. Because of vaporization combustion, the fan can supply less air or only a weaker supply to achieve a low flame. The flame size can be adjusted to suit different restaurant needs. 3. This burner head uses a linked oil valve and air valve principle, replacing the existing oil pump, nozzle, and controller. A pure copper needle valve and a 304 stainless steel air valve are connected in parallel, and through gear linkage, turning the oil valve also changes the airflow, achieving air-oil matching for more complete combustion. This mechanical principle greatly reduces the failure rate. 4. This burner head uses a large-cavity vaporization chamber, significantly reducing the probability of carbon buildup clogging the vaporization chamber. Attached Figure Description

[0020] Example 1

[0021] Please see the appendix Figure 1 The present invention provides a swirl-fired burner head, comprising a vaporization chamber 1, a vaporization plate 2, an oil bowl 4, a centrifugal shaft 5, an ignition needle 6, an atomizing oil pipe 7, an air duct 8, a main air outlet 10, a fire cage ring 11, a fan motor 12, a motor impeller 13, and a fan housing 15. The fire cage ring 11 and the oil bowl 4 are stepped, as are the oil bowl 4 and the air duct 8. The vaporization chamber 1 is located on top of the centrifugal shaft 5. The vaporization plate 2 and the vaporization chamber 1 are welded at four protruding points. There is a 3 mm gap between the vaporization chamber 1 and the vaporization plate 2. An air inlet plate 9 is provided on the lower side of the vaporization chamber 1. The inlet of the main oil inlet pipe 3 is provided above the vaporization plate 2. The air inlet plate 9 is connected to the inlet of the atomizing oil pipe 7. An air duct 14 is provided above the motor impeller 13.

[0022] Vaporization chamber 1 and centrifugal shaft 5 are fixed with screws.

[0023] The vaporization chamber 1 is concave-convex in shape.

[0024] The main oil inlet pipe 3 and the air duct 8 are welded together, and the ignition needle 6 and the air duct 8 are connected in a cross shape and fixed with screws.

[0025] The atomizing oil pipe 7 and the air duct 8 are welded together, and the air inlet plate 9 and the air duct 8 are welded together at their junction.

[0026] The fan motor 12 and the motor impeller 13 are rigidly connected.

[0027] A main air outlet 10 is provided on the side of the air duct 14.

[0028] A wind-oil linkage valve 16 is provided on the side of the main air outlet 10.

[0029] The air duct 8 and the fan housing 15 are connected by a flange.

[0030] Working Principle and Usage: When the power is turned on, the blower 12 rotates, simultaneously driving the vaporization chamber 1 to rotate at high speed. The solenoid valve of the main oil inlet pipe 3 opens, supplying oil to the vaporization chamber. Simultaneously, high-pressure air enters the oil bowl 4 from the air duct 14 and the fan disc 9. Multiple rows of air holes around the oil bowl blow air into its interior. When the manual button is turned on, the solenoid valve of the ignition atomizing oil pipe 7 opens, and the ignition needle 6 ignites the oil under high pressure. The atomizing oil pipe generates atomized oil through the high-pressure air, which is ignited by the ignition needle 6. The flame is blown into the oil bowl 4 through the multiple rows of air holes, re-igniting the oil centrifugally atomized in the vaporization chamber 1. At this point, the burner head is successfully ignited. Releasing the ignition switch stops the ignition needle 6, and the solenoid valve of the atomizing oil pipe 7 closes, stopping the oil supply. The burner head then burns normally. The size of the flame is controlled by the linkage between the needle-type oil valve and the air duct pressure relief valve. The airflow is controlled by the pressure relief of the air-oil linkage valve 16. Rotating the oil valve counterclockwise increases the oil flow, gradually closing the air pressure relief valve and increasing the air pressure. This reduces the reverse flame, achieving a balance between high airflow and high oil flow, and low airflow and low oil flow, ensuring complete combustion. Rotating the oil valve counterclockwise two full rotations results in maximum oil flow, while rotating the air valve half a rotation closes it completely, maximizing air pressure. Conversely, rotating counterclockwise closes the oil valve completely, opens the air pressure relief valve, minimizing airflow, and provides oil through a long-life oil passage. After approximately 3 to 10 seconds of ignition, the centrifugal force of the oil in the vaporization chamber causes it to rotate at high speed at the protruding part. The heat from the burner flame vaporizes the oil within the vaporization chamber, and the gas is discharged from the bottom of the vaporization chamber and combusted.

[0031] This invention provides a swirl-fired burner head. A rotating fan blows air and drives the internal vaporizer to rotate. High-pressure ignition and combustion for three to ten seconds ensure complete vaporization of the oil in the vaporization chamber, achieving 100% vaporization combustion, high oil utilization, and energy saving. Because of vaporization combustion, the fan can supply less air or a very weak airflow to achieve a low flame. The flame size can be adjusted to suit different restaurant needs. This burner head uses a linkage principle between the oil valve and the air valve, replacing the existing oil pump, nozzle, and controller. A pure copper needle valve and a 304 stainless steel air valve are connected in parallel, and through gear linkage, turning the oil valve also changes the airflow, achieving air-oil matching for more complete combustion. This mechanical principle greatly reduces the failure rate. The vaporization chamber of this burner head uses a large-cavity vaporization design, significantly reducing the probability of carbon buildup clogging the vaporization chamber.
