Description

Technical Field

[0001] This invention relates to the field of combustion medium nozzles, and more specifically to a nozzle atomizer and a burner device. Background Technology

[0002] Oil and gas stoves are widely used in hotels, restaurants, homes, and company canteens. The burner head is a key component of oil and gas stoves. Currently, the nozzles of burner heads on the market generally use high-pressure atomizing nozzles. These nozzles have multiple small-diameter spray holes. A high-pressure electromagnetic oil pump is used to pressurize the fuel and deliver it to the nozzle, so that the fuel is sprayed out through multiple spray holes to obtain atomized fuel, which is then ignited and burned by an igniter.

[0003] However, during combustion, the nozzle comes into contact with the combustion flame inside the fuel bowl. Due to the small diameter of the nozzle orifice, carbon deposits from unburned fuel easily adhere to the fuel injector at high temperatures, causing it to become clogged and unable to function properly, thus affecting its service life. At the same time, in order to ensure that the fuel has sufficient pressure to pass through the small nozzle orifice, the high-pressure atomizing nozzle must be used in conjunction with a high-pressure electromagnetic fuel pump. However, the high-pressure electromagnetic fuel pump needs to be controlled by an electronic controller, and it is prone to failure after long-term operation, resulting in high maintenance costs. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a nozzle atomizer and a burner head device, which has the advantages of being less prone to clogging and having a long service life. Moreover, it has a simple structure, is easy to assemble, and can effectively reduce costs.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: a nozzle atomizer, comprising a nozzle, a base and an oil inlet pipe connected in sequence; the upper part of the nozzle is provided with an atomizing nozzle, and a cavity communicating with the atomizing nozzle is formed between the lower part of the nozzle and the upper part of the base; the bottom wall of the base is provided with a mounting through hole and a plurality of first air inlets, the first air inlets communicating with the cavity; one end of the oil inlet pipe is connected to the mounting through hole and communicates with an oil spray port, the oil spray port being located in the cavity near the atomizing nozzle.

[0006] This technical solution provides a nozzle atomizer. Through the connection structure of the nozzle, base, and oil inlet pipe, the airflow entering the cavity from the first air inlet hole becomes a high-speed airflow when passing through the atomizing nozzle due to the narrowing of the airflow channel diameter. This airflow mixes with the fuel flowing out of the fuel injection port to form an atomized oil-gas mixture, which is then directly sprayed out through the larger diameter atomizing nozzle. This design is less prone to clogging, has a long service life, and features a simple structure and easy assembly, reducing maintenance and costs. Furthermore, the fuel flows directly to the fuel injection port through the oil inlet pipe, eliminating the need for high-pressure fuel compression. Therefore, this nozzle atomizer does not require a high-pressure electromagnetic oil pump; a mechanical handle oil valve is sufficient, solving the problem of easy damage to the high-pressure electromagnetic oil pump and thus reducing the cost of the burner unit.

[0007] In a preferred embodiment, the fuel injector and the fuel inlet pipe are integrally formed. The fuel inlet pipe includes a fuel injector, a fuel inlet, and a fuel inlet channel connecting the fuel injector and the fuel inlet. The diameter of the fuel injector is smaller than the diameter of the fuel inlet, and the diameter of the fuel injector is smaller than the diameter of the atomizing nozzle. In this embodiment, the fuel injector and the fuel inlet pipe are integrated. Therefore, the fuel inlet pipe is installed in the mounting through hole, with one end passing through the mounting through hole to allow the fuel injector to extend into the cavity near the atomizing nozzle. This design is simple and easy to install.

[0008] In a preferred embodiment, the fuel injector is located on the base and above the mounting through-hole. The diameter of the fuel injector is smaller than that of the mounting through-hole and smaller than the inner diameter of the fuel inlet pipe. One end of the fuel inlet pipe is threaded into the mounting through-hole for a more secure connection, thus providing better stability and sealing for the atomizer. In this embodiment, the fuel injector is integrated into the base; therefore, only the outlet end of the fuel inlet pipe needs to be connected to the mounting through-hole, and fuel will be directly ejected from the fuel injector on the base.

[0009] In a preferred embodiment, the fuel injector and the base are integrally formed, or the fuel injector is detachably connected to the base via a threaded structure, facilitating the replacement of fuel injectors of different diameters.

[0010] Furthermore, the outer walls of both the upper and lower ends of the oil inlet pipe are threaded, and the inner wall of the mounting through hole is threaded, with the upper end of the oil inlet pipe connected to the mounting through hole by threads.

[0011] In a preferred embodiment, the base has an outwardly extending edge at its bottom, and the edge has multiple second air inlets. The second air inlets are used to communicate with the inner cavity of the burner head device, so that external air can enter the inner cavity of the burner head device through the second air inlets, thereby supplementing the combustion chambers inside the burner head device with air and aiding combustion.

[0012] In a preferred embodiment, multiple first air inlets are evenly distributed around the mounting through hole. The first air inlets are straight holes or spiral holes to facilitate the uniform entry of air into the cavity and ensure atomization effect. Multiple second air inlets are evenly distributed circumferentially along the edge. The second air inlets are straight holes or spiral holes to ensure uniform air intake into the inner cavity of the burner head device, thereby improving the combustion effect.

[0013] In a preferred embodiment, the edge portion is in the shape of an annular cone, a polygonal pyramid, an annular plate, or a polygonal plate.

[0014] In a preferred embodiment, the bottom wall edge of the base has an upwardly protruding annular mounting portion; the nozzle is sealed and connected within the annular mounting portion, and a cavity is formed between the conical surface at the bottom of the nozzle and the top surface of the bottom wall of the base. The conical surface at the bottom of the nozzle, together with the top surface of the bottom wall of the base, forms a cavity with an inner diameter that gradually decreases from bottom to top, causing the airflow channel diameter to gradually decrease until a high-speed airflow is formed at the atomizing nozzle, thereby achieving a better atomization effect.

[0015] In a preferred embodiment, the inner wall of the annular mounting portion is connected to the outer wall of the nozzle by a thread, which provides good sealing and facilitates assembly.

[0016] A burner assembly includes an air inlet component, a housing, a first oil bowl, a second oil bowl, a bowl cover, flame spreaders, a flame ring, an igniter, and a nozzle atomizer as described in any of the above technical solutions. The bottom end of the housing is connected to the air inlet component, which has an air inlet channel. The first oil bowl is located inside the housing, with a mixed oil-gas inlet at its bottom and an air inlet hole on its surface. The ignition needle of the igniter is located inside the first oil bowl. The second oil bowl is located inside the first oil bowl, with teeth at its bottom. The first oil bowl has a conical protrusion and a first oil-gas hole; the second oil bowl has a second oil-gas hole on its side wall; a bowl cover is placed on top of the second oil bowl, and the bowl cover has a third oil-gas hole; a flame spreader is placed above the second oil bowl, and the side wall of the flame spreader has multiple flame spread holes; a flame gatherer is placed on top of the first oil bowl and outside the flame spreader, with the top of the flame gatherer higher than the top of the flame spreader; a base is placed between the air inlet channel and the inner cavity of the shell; the atomizing nozzle is located inside the mixed oil-gas inlet; and the oil inlet pipe extends downwards from the bottom wall of the air inlet component. Specifically, when the burner is working, the atomizing nozzle sprays atomized mixed oil and gas into the first oil bowl through the mixed oil and gas inlet. The sprayed atomized mixed oil and gas impacts the toothed conical protrusion at the bottom of the second oil bowl, achieving secondary atomization, and then is ignited and burned by the igniter. While the atomized mixed oil and gas is burning in the first oil bowl, the heat generated by the combustion heats the first and second oil bowls. When the atomized mixed oil and gas comes into contact with the heated first and second oil bowls, it can quickly vaporize the liquid mixed oil and gas, thereby achieving the purpose of complete combustion.

[0017] The burner device in this technology can achieve three-stage mixing and three-stage combustion by using the air injected by the air intake component, thereby achieving complete combustion, which is energy-saving, environmentally friendly, and highly safe. At the same time, the above-mentioned nozzle atomizer is not easy to clog and has a long service life. Moreover, it does not require the use of electronic controllers, high-pressure electromagnetic oil pumps and heaters, which makes it more stable, more energy-saving and environmentally friendly, and can also reduce maintenance costs.

[0018] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention provides a nozzle atomizer. Through the connection structure of the nozzle, base, and oil inlet pipe, the airflow entering through the first air inlet hole becomes a high-speed airflow as it passes through the atomizing nozzle due to the narrowing of the airflow channel diameter. This airflow mixes with the fuel flowing out of the fuel injector, forming an atomized fuel-air mixture. This mixture is then directly sprayed out through the larger diameter atomizing nozzle, making it less prone to clogging, resulting in a long service life. Moreover, the structure is simple and easy to assemble, reducing maintenance work and lowering costs. In addition, the fuel flows directly to the fuel injector through the oil inlet pipe, and the entire process can be achieved without high-pressure compression of the fuel. Therefore, this nozzle atomizer does not need to be used in conjunction with a high-pressure electromagnetic oil pump; a mechanical handle oil valve can be used instead, solving the problem of easy damage to the high-pressure electromagnetic oil pump and thus reducing maintenance costs.

[0020] A burner device employing the aforementioned nozzle atomizer can achieve full fuel atomization and three-stage combustion, thereby achieving complete combustion, saving energy and protecting the environment; moreover, the nozzle is not easily clogged, has a long service life, and low maintenance costs.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] Reference Figure 1-14 This invention describes a nozzle atomizer 10 and a stove head device 20 according to an embodiment of the present invention.

[0041] In one embodiment, such as Figure 1-2 As shown, a nozzle atomizer 10 is applied to a stove head device 20. The nozzle atomizer 10 includes a nozzle 11, a base 12 and an oil inlet pipe 13 connected in sequence.

[0042] like Figure 7 As shown, the upper part of the nozzle 11 is provided with an atomizing nozzle 110, and the lower part of the nozzle 11 and the upper part of the base 12 form a cavity communicating with the atomizing nozzle 110; the bottom wall of the base 12 is provided with an installation through hole 120 and a plurality of first air inlets 121, the first air inlets 121 communicating with the cavity; the bottom of the base 12 is provided with an outwardly extending edge, the edge being provided with a plurality of second air inlets 122, the second air inlets 122 being used to communicate with the inner cavity of the burner device 20; one end of the oil inlet pipe 13 is connected to the installation through hole 120 and communicates with an oil spray port 131, the oil spray port 131 being located in the cavity near the atomizing nozzle 110, and is used to spray fuel oil.

[0043] The burner head device 20 can be the burner head of a fuel oil or gas stove, and the atomizer 10 can be installed at the bottom of the burner head device 20. Specifically, the base 12 can be located between the inner cavity of the burner head device 20 and the air inlet channel. The first air inlet 121 and the second air inlet 122 are respectively connected to the air inlet channel of the burner head device 20. The atomizing nozzle 110 is located at the mixed oil and gas inlet of the oil bowl in the inner cavity of the burner head device 20, and the mixed atomized fuel is sprayed into the oil bowl for ignition and combustion. Preferably, the oil inlet pipe 13 can adopt a straight pipe structure, which requires less pressure for oil inlet and has a simple structure, making it easy to assemble.

[0044] The working principle of the above-mentioned nozzle atomizer 10 is as follows: The airflow flowing in through the first air inlet 121 enters the cavity formed between the nozzle 11 and the base 12. When flowing through the atomizing nozzle 110, the airflow diameter decreases, the air is compressed, forming an airflow difference and accelerating the airflow. A high-speed airflow is formed at the atomizing nozzle 110, which mixes with the fuel and gas flowing out of the fuel injection port 131 to form an atomized oil-gas mixture. The atomizing nozzle 110 sprays the atomized oil-gas mixture into the combustion chamber of the burner device 20. The atomized oil-gas mixture impacts the toothed conical protrusion of the oil cup in the combustion chamber to achieve re-atomization, and then is ignited and burned by the igniter. The atomization effect is better, which helps to improve the combustion efficiency. At the same time, the second air inlet 122 is located outside the cavity and is not connected to the cavity. A portion of the air entering the air intake channel of the burner device 20 can enter the inner cavity of the burner device 20 through multiple second air inlets 122 to supply the combustion chamber inside the burner device 20, thus playing a role in combustion assistance.

[0045] In the aforementioned nozzle atomizer 10, since there is no need to spray fuel through a small nozzle, there is no need to apply high pressure to compress the fuel. Therefore, in actual use, the burner device 20 using this nozzle atomizer 10 can use a mechanical handle oil valve to control the oil volume, eliminating the need for an electronic controller and a high-pressure electromagnetic oil pump, thus effectively reducing maintenance costs.

[0046] In the above embodiments, the nozzle atomizer 10, through the connection structure of the nozzle 11, base 12, and oil inlet pipe 13, enables the airflow entering from the first air inlet 121 to form a high-speed airflow when passing through the atomizing nozzle 110, due to the narrowing of the airflow channel diameter. This airflow mixes with the fuel flowing out of the fuel injection port 131 to form an atomized oil-gas mixture, which is then directly sprayed out through the larger diameter atomizing nozzle 110. This process is less prone to clogging, has a long service life, and features a simple structure and convenient assembly, reducing maintenance work and lowering costs. Furthermore, since the fuel flows directly to the fuel injection port 131 through the oil inlet pipe 13, the entire process can be achieved without high-pressure compression of the fuel. Therefore, the nozzle atomizer 10 does not need to be used in conjunction with a high-pressure electromagnetic oil pump; a mechanical handle oil valve can be used instead, solving the problem of easy damage to the high-pressure electromagnetic oil pump and thus reducing maintenance costs.

[0047] In one embodiment, such as Figure 1-2 As shown, the fuel injector 131 and the fuel inlet pipe 13 are integrally formed. The fuel inlet pipe 13 is installed inside the mounting through hole 120, with one end passing through the mounting through hole 120 to allow the fuel injector 131 to extend into the cavity near the atomizing nozzle 110. The structure is simple and easy to install. The fuel inlet pipe 13 includes the fuel injector 131, the fuel inlet 132, and the fuel inlet channel 133 connecting the fuel injector 131 and the fuel inlet 132. The diameter of the fuel injector 131 is smaller than the diameter of the fuel inlet 132, and the diameter of the fuel injector 131 is smaller than the diameter of the atomizing nozzle 110.

[0048] The nozzle 131 has a diameter of 1-3 mm, and the inlet 132 has a diameter of 3-8 mm. The inlet channel 133 has a first connecting section and a second connecting section. The first connecting section is connected to the nozzle 131, and the second connecting section is connected to the inlet 132. The inner diameter of the first connecting section is the same as the diameter of the nozzle 131, and the inner diameter of the second connecting section is the same as the diameter of the inlet 132.

[0049] In practice, the diameter of the fuel injector 131 can be 1mm, 2mm, 3mm, etc., and the diameter of the fuel inlet 132 can be 3mm, 5mm, 8mm, etc.

[0050] In another embodiment, such as Figure 3 As shown, the fuel injector 131 is located on the base 12 and above the mounting through hole 120. The diameter of the fuel injector 131 is smaller than the diameter of the mounting through hole 120 and the diameter of the fuel injector 131 is smaller than the inner diameter of the fuel inlet pipe 13. One end of the fuel inlet pipe 13 is threaded into the mounting through hole 120.

[0051] In practice, the fuel injector 131 is integrated on the base 12. Therefore, the fuel outlet of the fuel inlet pipe 13 can be connected to the mounting through hole 120, and the fuel will be sprayed directly from the fuel injector 131 on the base 12.

[0052] As an embodiment of the above-described embodiments, the fuel injector 131 and the base 12 can be integrally formed, or the injector 131 can be detachably connected to the base 12 via a threaded structure. When the fuel injector 131 is connected to the base 12 via a threaded structure, fuel injectors 131 of different diameters can be replaced according to actual usage requirements. The base 12 is provided with a threaded interface for connecting the fuel injector 131, and the fuel injector 131 can be connected to the base 12 via a threaded structure.

[0053] As one embodiment of the above-described embodiment, the outer walls of both the upper and lower ends of the oil inlet pipe 13 are threaded, and the inner wall of the mounting through hole 120 is threaded. The upper end of the oil inlet pipe 13 is connected to the mounting through hole 120 by threads, making the connection more stable and thus giving the nozzle atomizer 10 better stability and sealing. When the nozzle atomizer 10 is applied to the burner device 20, the threaded outer wall of the lower end of the oil inlet pipe 13 facilitates the connection to the fuel source.

[0054] In this embodiment, a plurality of first air inlets 121 are evenly distributed around the mounting through hole 120, and the first air inlets 121 are straight holes or spiral holes.

[0055] The mounting through hole 120 is used to install and allow the oil inlet pipe 13 to pass through. The multiple first air inlets 121 are set as straight holes or spiral holes evenly distributed around the mounting through hole 120, so that the airflow entering through the multiple first air inlets 121 can enter the cavity evenly to ensure the atomization effect.

[0056] In this embodiment, a plurality of second air inlets 122 are evenly distributed circumferentially on the edge portion. The second air inlets 122 are straight holes or spiral holes, which can ensure uniform air intake into the inner cavity of the burner head device 20, thereby improving the combustion-supporting effect.

[0057] In different embodiments, the edge portion can be... Figure 4-6 and Figure 8-9 The ring-shaped cone shown Figure 1-3 The polygonal shape shown Figure 10-11 The annular plate or Figure 12-13 The nozzle atomizer 10 is shown in a multi-faceted plate shape. The thickness of the edge portion can be less than the thickness of the bottom wall of the base 12, primarily used for setting the second air inlet 122 and for mounting on the burner head device 20. It should be noted that the aforementioned annular cone, multi-faceted cone, annular plate, or multi-faceted plate shapes are only several feasible implementations of the nozzle atomizer 10. In specific implementations, the edge portion can adopt other structures for setting the second air inlet 122. Specifically, the edge portion can be at a certain angle to the bottom wall of the base 12, or it can be parallel to the bottom wall of the base 12.

[0058] In yet another embodiment, such as Figure 4-6 As shown, the edge is annularly conical, and the second air inlet 122 is perpendicular to the edge, being a through hole that slopes outward from bottom to top. The oil injection port 131 and the base 12 are integrally formed. In specific implementation, since the air inlet of the combustion chamber is generally located on the side of the oil bowl, external air enters the inner cavity of the burner device 20 obliquely through the second air inlet 122. The entry position is closer to the outer side of the oil bowl, which facilitates the air entering the combustion chamber through the air inlet to aid combustion. Moreover, the structure is simple and can save installation space.

[0059] In the above embodiments, the number of first air inlets 121 can be 2 to 8, and the number of second air inlets 122 can be 6 to 16; for example, in one embodiment of this embodiment, the number of first air inlets 121 can be 5, and the number of second air inlets 122 can be 12.

[0060] In practical applications, the number of the first air inlet 121 and the second air inlet 122 can also be set to other values ​​according to the actual needs of the product.

[0061] In this embodiment, the bottom wall edge of the base 12 is provided with an upwardly protruding annular mounting portion 123; the nozzle 11 is sealed and connected in the annular mounting portion 123, and a cavity is formed between the conical surface at the bottom of the nozzle 11 and the top surface of the bottom wall of the base 12.

[0062] The nozzle 11 has a conical surface at its bottom, which forms a conical cavity with the bottom wall and top surface of the base 12. The upper end of the cavity is connected to the nozzle 110, and the lower end is connected to the first air inlet 121. The oil injection port 131 is located in the cavity near the atomizing nozzle 110.

[0063] In practice, fuel and air can enter the cavity through the fuel inlet pipe 13 and the first air inlet 121, respectively. As the inner diameter of the cavity gradually decreases from bottom to top, the airflow channel diameter gradually decreases until a high-speed airflow is formed at the atomizing nozzle, thereby achieving a better atomization effect.

[0064] In this embodiment, the inner wall of the annular mounting portion 123 is connected to the outer wall of the nozzle 11 by a thread. The inner wall of the annular mounting portion 123 and the outer wall of the nozzle 11 are provided with matching threads, which can realize a threaded connection, provide good sealing performance, and facilitate assembly.

[0065] In another embodiment, such as Figure 5As shown, the present invention provides a burner device 20, which can be applied to stoves such as oil or gas stoves. The burner device 20 includes an air inlet component 21, a housing 22, a first oil bowl 23, a second oil bowl 24, a bowl cover 25, flame spreaders 26, a flame ring 27, an igniter 28, and a nozzle atomizer 10 as described in any of the above embodiments; the bottom end of the housing 22 is connected to the air inlet component 21, and the air inlet component 21 has an air inlet channel; the first oil bowl 23 is disposed inside the housing 22, and the bottom of the first oil bowl 23 has a mixed oil-gas inlet, and the first oil bowl 23 also has an air inlet hole; the ignition needle of the igniter 28 is located inside the first oil bowl 23; the second oil bowl 24 is disposed inside the first oil bowl 23, and the bottom of the second oil bowl 24... The first oil bowl 23 has a toothed conical protrusion and a first oil-gas hole. The second oil bowl 24 has a second oil-gas hole on its side wall. The bowl cover 25 covers the top of the second oil bowl 24 and has a third oil-gas hole. The flame spreader 26 is located above the second oil bowl 24 and has multiple flame spreaders on its side wall. The flame gatherer 27 is located on the top of the first oil bowl 23 and outside the flame spreader 26. The top of the flame gatherer 27 is higher than the top of the flame spreader 26. The base 12 is located between the air inlet channel and the inner cavity of the housing 22. The atomizing nozzle 110 is located inside the mixed oil-gas inlet. The oil inlet pipe 13 extends downward from the bottom wall of the air inlet component 21.

[0066] The first combustion chamber is formed between the inner wall of the first oil bowl 23 and the outer wall of the second oil bowl 24, the second combustion chamber is formed between the second oil bowl 24 and the bowl cover 25, and the third combustion chamber is formed between the bowl cover 25 and the flame spreader 26. The three combustion chambers are connected in sequence.

[0067] The working principle of the aforementioned burner device 20 is as follows: The nozzle atomizer 10 mixes and atomizes the fuel with the air entering through the first air inlet 121. The resulting atomized fuel mixture enters the first combustion chamber through the atomizing nozzle 110, impacting the toothed conical protrusion at the bottom of the second oil bowl 23 within the first combustion chamber for re-atomization. It is then ignited by the ignition needle. The incompletely burned atomized fuel mixture then sequentially enters the second and third combustion chambers, mixing with the air entering the inner cavity of the housing 22 through the second air inlet 122 for continued combustion, thus achieving complete combustion. Simultaneously, the atomized fuel mixture burns in the first combustion chamber, heating both the first and second oil bowls. The contact between the atomized fuel mixture and the heated first and second oil bowls rapidly vaporizes the liquid fuel mixture, achieving complete combustion.

[0068] Since the fuel enters the cavity directly through the oil inlet pipe 13, the entire process can be achieved without high-pressure compression of the fuel. Therefore, the burner device 20 does not need to be used with a high-pressure electromagnetic oil pump; a mechanical handle oil valve is sufficient. This solves the problem of easy damage to the high-pressure electromagnetic oil pump, resulting in low maintenance costs and convenient and safe operation. Moreover, the mixed oil and gas can be directly ignited and burned after atomization, heating the oil bowl simultaneously to achieve vaporization. There is no need to use an additional heater to heat the atomized oil and gas, further improving energy efficiency. In addition, the high-speed high-pressure blower connected to the air inlet channel can be replaced by a regular pressure AC blower, thus solving the problem of unstable small flame control in the existing technology and improving energy efficiency. Therefore, in specific implementation, the burner device 20 can achieve premixed atomization, vaporization, and combustion of fuel without an electronic controller, high-pressure electromagnetic oil pump, high-pressure atomizing nozzle, heater, etc.

[0069] The aforementioned burner device 20 can achieve full atomization, gasification, and three-stage combustion of fuel, thereby achieving complete combustion, which is energy-saving, environmentally friendly, and highly safe. At the same time, by using the nozzle atomizer 10 in the above embodiments, the nozzle is not easy to clog and has a long service life. Moreover, it does not require the use of electronic controllers, high-pressure electromagnetic oil pumps, and heaters, resulting in good stability, greater energy saving and environmental protection, and reduced maintenance costs.

[0070] Currently, kitchen fuels are generally liquefied petroleum gas (LPG) and natural gas, which are flammable and explosive fuels, posing significant safety hazards and being non-renewable resources. The atomizer 10 and burner device 20 provided by this invention can atomize and fully combust fuels such as waste cooking oil and coal-to-oil. Since waste cooking oil and coal-to-oil are not classified as hazardous chemicals and have high flash points, making them difficult to ignite with an open flame, this invention solves the problem of the flammability and explosiveness of existing fuels. Furthermore, waste cooking oil is a renewable resource that can be recycled, making it more energy-efficient and environmentally friendly. Therefore, the atomizer 10 and burner device 20 provided by this invention can rationally utilize new energy fuels such as waste cooking oil and coal-to-oil, enabling them to function in various places requiring stove heating, such as hotels and canteens.

[0071] Other configurations and operations of the nozzle atomizer 10 and the burner device 20 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
