Description

Technical Field

[0001] This invention belongs to the field of liquid fuel stove technology, and particularly relates to a burner. Background Technology

[0002] Alcohol-oil stoves are a new type of energy-saving stove based on alcohol-based fuel. They are an extension of energy-saving stoves based on diesel and liquefied petroleum gas. They have the original functions of energy-saving stoves based on diesel and liquefied petroleum gas, but use environmentally friendly, clean and efficient alcohol-based oil as fuel. With a special high-efficiency energy-saving alcohol-based oil burner core, the alcohol-based oil is completely and fully burned, with high heat conversion efficiency and the emitted gases are water and carbon dioxide.

[0003] Existing burners, such as the one with patent number CN110397956A, can use various liquid fuels. When the air blown in from the fan through the air duct, it blows against the side wall of the internal combustion chamber, changing the fan's air from cold to hot, thus eliminating the need for preheating and saving thermal energy. In this invention, the fan air can enter the ignition chamber from the cooling air vent. On the one hand, it can provide oxygen to the ignition needle, making the high flash point fuel easier to ignite after atomization, avoiding fuel waste and environmental pollution caused by delayed ignition.

[0004] However, during use, it was found that some of the gas was not fully burned before overflowing from the combustion chamber, resulting in a waste of gas. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a burner that enables more complete combustion of fuel and improves fuel utilization.

[0006] In view of this, the present invention provides a burner comprising:

[0007] An ignition chamber is provided with an ignition component and an atomizing nozzle assembly. The atomizing nozzle assembly is used to spray fuel, and the ignition component is used to ignite the fuel.

[0008] A combustion chamber is located above the ignition chamber and is connected to the ignition chamber via a fire hole. Cooking utensils are placed above the combustion chamber.

[0009] The air intake chamber is provided with an air inlet, through which combustion-supporting gas can enter the air intake chamber. The air intake chamber is connected to both the ignition chamber and the combustion chamber.

[0010] The combustion chamber is equipped with a swirl assembly, which is used to create a swirl of fuel within the combustion chamber.

[0011] In this technical solution, the swirl assembly is used to create a swirl of fuel in the combustion chamber, which increases the fuel travel distance, increases the fuel time in the combustion chamber, improves the uniformity of fuel-air mixing, and allows the fuel to be burned more completely, thereby improving fuel utilization.

[0012] Furthermore, the swirl assembly is placed in the combustion chamber and is coaxially arranged above the fire passage. The swirl assembly has multiple swirl holes arranged along the axis of the swirl assembly. Each swirl hole is located outside the fire passage and is inclined.

[0013] In this technical solution, by setting up a swirl assembly, the fuel after ignition cannot directly enter the combustion chamber from the flame hole, but expands outward and enters the upper part of the combustion chamber from the swirl hole. Since the swirl hole is inclined, the swirl assembly makes both the fuel and the flame rotate before entering the combustion chamber, increasing the fuel's travel distance and the time the fuel spends in the combustion chamber, which can make the fuel burn more completely and improve fuel utilization.

[0014] Furthermore, the swirling orifice includes two types of orifices with kidney-shaped and circular cross-sectional shapes.

[0015] Furthermore, the air intake chamber surrounds the area where it connects to the ignition chamber and the combustion chamber, and air passages are provided on the side walls of both the ignition chamber and the combustion chamber.

[0016] Furthermore, a blocking and dispersing component is provided between the swirl assembly and the air inlet, and the blocking and dispersing component is connected to the power structure and can rotate axially.

[0017] In this technical solution, by setting a blocking and dispersing component above the air intake, the fuel sprayed from the atomizing nozzle assembly impacts the blocking and dispersing component and disperses, preventing it from directly swirling into the upper part of the combustion chamber. Instead, it burns fully at the air intake orifice. Furthermore, the power structure causes the blocking and dispersing component to rotate circumferentially, allowing some of the fuel adhering to the blocking and dispersing component to rotate, disperse, and burn along with it. This increases the fuel's travel distance, increases the time the fuel spends in the combustion chamber, improves the uniformity of fuel-air mixing, and allows the fuel to burn more completely, thereby improving fuel utilization.

[0018] Furthermore, the blocking and dispersing component includes several fixedly connected discs, each disc including an end plate and multiple wheel pieces arranged around the axis of the end plate. The wheel pieces are vertically arranged on the end face of the wheel piece relative to the end plate, and the wheel pieces are inclined relative to the diameter of the end plate. All discs are coaxial and their ends are fixedly connected.

[0019] Furthermore, the power structure includes:

[0020] A rotating shaft is rotatably disposed in the combustion chamber and horizontally positioned above the fire passage. The aforementioned wheel is coaxially fixed on the rotating shaft. One end of the rotating shaft extends out of the combustion chamber and into the air intake chamber. The rotating shaft is located on the side above the air intake.

[0021] A drive impeller is fixedly sleeved on the extended end of the shaft that extends into the air inlet chamber.

[0022] In this technical solution, the combustion-supporting gas enters the intake chamber through the air inlet, which can generate a lateral driving force on the drive impeller, causing the drive impeller to rotate and drive the shaft to rotate, thus realizing the rotation of the impeller and achieving full mixing of fuel and air.

[0023] Furthermore, the number of wheel pieces on the discs is not the same, and the wheel pieces on adjacent discs are staggered.

[0024] In this technical solution, the same noise spectrum can be avoided when all the discs cut the ejected fuel and flame at the same time, thus avoiding the howling sound caused by the superposition of the same noise spectrum, thereby reducing the noise that obstructs the operation of the dispersion component and improving the sound quality.

[0025] Furthermore, the atomizing nozzle assembly includes a tube body, a connecting nut is threaded onto the outside of the tube body, a nozzle is fixedly installed on the top of the tube body, an ignition needle is installed on the side of the connecting nut, and the distance between the side of the nozzle and the top of the ignition needle is three millimeters.

[0026] Furthermore, the blocking and dispersing component is made of copper alloy material.

[0027] In this technical solution, the copper alloy material makes the blocking and dispersing parts resistant to high temperatures, lightweight, and with strong thermal conductivity, enabling them to transfer heat to the cookware above the combustion chamber.

[0028] The beneficial effects of this invention are:

[0029] 1. By using a swirl assembly to create a swirling flow of fuel in the combustion chamber, the fuel travel distance and time in the combustion chamber can be increased, improving the uniformity of fuel-air mixing, resulting in more complete combustion and improved fuel utilization.

[0030] 2. By installing a deflector above the air intake, the fuel sprayed from the atomizing nozzle assembly impacts the deflector and disperses, preventing it from directly swirling into the combustion chamber. Instead, it burns fully at the air intake orifice. Furthermore, the power structure causes the deflector to rotate circumferentially, allowing some of the fuel adhering to it to rotate, disperse, and burn. This increases the fuel's travel distance and time within the combustion chamber, improving the uniformity of fuel-air mixing and resulting in more complete combustion and higher fuel efficiency.

[0031] 3. The staggered arrangement of the discs on adjacent discs avoids the generation of the same noise spectrum caused by all discs cutting the ejected fuel and flame at the same time. This prevents the superposition of the same noise spectrum and the resulting howling sound, thereby reducing the noise from the obstructing components and improving the sound quality.

Additionally, features described with reference to certain examples may be combined in other examples.

[0047] Example 1:

[0048] like Figure 1-2 As shown, a burner includes an ignition chamber 1, a combustion chamber 2, and an air intake chamber 3. The ignition chamber 1 contains an ignition assembly 10 and an atomizing nozzle assembly 5. The atomizing nozzle assembly 5 sprays fuel, and the ignition assembly 10 ignites the fuel. The combustion chamber 2 is located above the ignition chamber 1 and is connected to the ignition chamber 1 via a flame port 18. Cooking utensils are placed on top of the combustion chamber 2. The air intake chamber 3 surrounds the connection between the ignition chamber 1 and the combustion chamber 2. Both the ignition chamber 1 and the combustion chamber 2 have vent holes 20 on their side walls. The air intake chamber 3 has an air inlet 17, through which combustion-supporting gas can enter the air intake chamber 3. The air intake chamber 3 is connected to both the ignition chamber 1 and the combustion chamber 2 via the vent holes 20.

[0049] A swirl assembly 4 is provided inside the combustion chamber 2. The swirl assembly 4 is used to create a swirling flow of fuel within the combustion chamber 2. By creating a swirling flow of fuel within the combustion chamber 2 using the swirl assembly 4, the travel distance of the fuel can be increased, the time the fuel spends in the combustion chamber 2 can be increased, the uniformity of fuel-air mixing can be improved, the fuel can be burned more completely, and the fuel utilization rate can be improved.

[0050] Example 2:

[0051] like Figure 1-2 As shown, the atomizing nozzle assembly 5 includes a tube body 6, a connecting nut 7 is threaded onto the outside of the tube body 6, a nozzle 8 is fixedly installed on the top of the tube body 6, an ignition needle 9 is installed on the side of the connecting nut 7, and the distance between the side of the nozzle 8 and the top of the ignition needle 9 is three millimeters.

[0052] Example 3:

[0053] like Figure 2-6 As shown, the swirl assembly 4 is placed inside the combustion chamber 2 and is coaxially positioned above the flame guide hole 18. The swirl assembly 4 has multiple swirl holes 11 arranged along its axial direction, each located outside the flame guide hole 18, and the swirl holes 11 are inclined. The swirl holes 11 include two types with cross-sectional shapes: kidney-shaped and circular. By setting the swirl assembly 4, the ignited fuel cannot directly enter the combustion chamber 2 through the flame guide hole 18, but instead expands outwards and enters the combustion chamber 2 above the swirl holes 11. Since the swirl holes 11 are inclined, the swirl assembly 4 ensures that both the fuel and flame rotate before entering the combustion chamber 2, increasing the fuel's travel distance and time within the combustion chamber 2, resulting in more complete combustion and improved fuel utilization. Figure 8 As shown, a cover plate 21 is also provided above the swirl assembly 4, and a flame outlet 22 is provided on the cover plate. The flame outlet 22 is inclined.

[0054] Example 4:

[0055] like Figure 2 and Figure 7 As shown, a blocking and dispersing component 12 is also provided between the swirl assembly 4 and the air inlet 17. The blocking and dispersing component 12 is connected to the power structure and can rotate axially. The blocking and dispersing component 12 is made of copper alloy. The copper alloy material makes the blocking and dispersing component 12 resistant to high temperatures, lightweight, and has strong thermal conductivity, enabling it to transfer heat to the cookware above the combustion chamber 2.

[0056] The blocking and dispersing component 12 includes several fixedly connected discs 13. Each disc 13 includes an end plate 19 and multiple wheel pieces 14 arranged around the axis of the end plate 19. The wheel pieces 14 are vertically arranged on the end face of the wheel piece 14 relative to the end plate 19 and are inclined relative to the diameter of the end plate 19. All discs 13 are coaxial and their ends are fixedly connected. The power structure includes a rotating shaft 15 and a drive impeller 16. The rotating shaft 15 is rotatably arranged in the combustion chamber 2 and horizontally arranged above the fire hole 18. The discs 13 are coaxially fixedly arranged on the rotating shaft 15. One end of the rotating shaft 15 extends out of the combustion chamber 2 and extends into the intake chamber 3. The rotating shaft 15 is located on the side above the intake port 17. The drive impeller 16 is fixedly sleeved on the extended end of the rotating shaft 15 that extends into the intake chamber 3. Combustion-supporting gas enters the intake chamber 3 through the intake port 17, which can generate a lateral driving force on the drive impeller 16, causing the drive impeller 16 to rotate and drive the rotating shaft 15 to rotate.

[0057] By setting a blocking and dispersing element 12 above the air inlet 17, the fuel sprayed from the atomizing nozzle assembly 5 can impact the blocking and dispersing element 12 and disperse, preventing it from directly swirling into the upper part of the combustion chamber 2. Instead, it can be fully burned at the orifice of the air inlet 17. Furthermore, the power structure causes the blocking and dispersing element 12 to rotate circumferentially, allowing some of the fuel adhering to the blocking and dispersing element 12 to rotate, disperse, and burn along with it. This increases the fuel's travel distance, increases the time the fuel spends in the combustion chamber 2, improves the uniformity of fuel-air mixing, and allows the fuel to burn more completely, thereby improving fuel utilization.

[0058] Example 5:

[0059] like Figure 2 and Figure 7 As shown, the number of wheel pieces 14 on the wheel 13 is different, and the wheel pieces 14 on adjacent wheel 13 are staggered. This avoids the generation of the same noise spectrum due to all wheel pieces 14 cutting the ejected fuel and flame at the same time, thereby avoiding the howling sound caused by the superposition of the same noise spectrum, and thus reducing the noise of the obstruction and dispersion component 12 and improving the sound quality.

[0060] In the specific operation, the atomizing nozzle assembly 5 sprays fuel outward, which is ignited by the ignition assembly 10. Simultaneously, the combustion-supporting gas enters the intake chamber 3 through the air inlet 17. After being preheated, the combustion-supporting gas enters the ignition chamber 1 and combustion chamber 2 through the air inlet 17. The gas in the ignition chamber 1 can also enter the combustion chamber 2 through the flame hole 18. The sprayed fuel is blocked and dispersed by the blocking and dispersing component 12, achieving full mixing of fuel and air. The parallel swirl assembly 4 forms a swirl, increasing the fuel's travel distance and the time it spends in the combustion chamber 2, improving the uniformity of fuel-air mixing, allowing for more complete combustion and improving fuel utilization. At the same time, the wheel pieces 14 on adjacent discs 13 are staggered, which avoids the generation of the same noise spectrum caused by all discs 13 cutting the sprayed fuel and flame at the same time. This avoids the whistling sound caused by the superposition of the same noise spectrum, thereby reducing the noise of the blocking and dispersing component 12 and improving sound quality.

[0061] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
