Description

[Technical Field]

[0001] The present invention relates to the agricultural machinery technical field, and more particularly to a burner structure of a steam sprayer and a steam sprayer. [Background technology]

[0002] Sprayers are agricultural and forestry plantation protection machinery and equipment that are widely used for pest control, disinfection, sterilization, or fertilization. Sprayers include fog machines and steam sprayers. Steam sprayers separate the chemical agent and the auxiliary agent, heat the auxiliary agent alone, and then mix the room-temperature chemical agent with the high-temperature heated auxiliary agent and spray it, ensuring the efficacy of the chemical agent. In addition, steam sprayers have the advantages of being smaller in volume and lighter in weight than fog machines. Therefore, steam sprayers are more widely used.

[0003] When using a conventional steam sprayer, heat is absorbed through a single-layer heat-absorbing coil tube installed inside the sprayer, but only 60% of the heat is absorbed. Some of the heat is lost to the air through the outer shell, resulting in low heat utilization. Furthermore, conventional steam sprayers typically have an exhaust port directly attached to the burner to discharge smoke and gas. During use, high temperatures are generated by the smoke and flames at the exhaust port, making it easy for users to be burned and, in severe cases, causing fires and other problems, resulting in low safety and overall operational disadvantages. At the same time, the machine is noisy during operation, affecting the user experience. Furthermore, conventional sprayers typically use a plunger pump to inject a certain amount of fuel when igniting, which results in slow ignition, high ignition power, and high fuel consumption. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to solve at least one of the technical problems in the prior art, and therefore aims to provide a steam atomizer that is simple in structure, reduces the probability of burns, reduces noise, and improves safety and reliability. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0034]

[0023] The following detailed description of the embodiments of the present invention is provided in the drawings, and the same or similar reference numerals throughout the drawings denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are intended to illustrate the present invention only and should not be construed as limiting the present invention.

[0035] A steam atomizer 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0036] As shown in FIGS. 1 to 12, a steam sprayer 100 according to an embodiment of the present invention includes a blower section 10, a combustion section assembly 20, a burner structure 30, and an exhaust pipe structure 40.

[0037] The blower 10 has an air outlet 11, and the combustion section assembly 20 includes a combustion section housing 21 and a combustion section 22. One side of the combustion section housing 21 has an intake passage and the other side is open. As shown in Fig. 2, the left side of the combustion section housing 21 has an intake passage that is connected to the air outlet 11, the right side of the combustion section housing 21 is open, and at least a portion of the combustion section 22 (e.g., the left portion) is provided to penetrate the open side. The blower 10 is configured to introduce an airflow into the combustion section assembly 20, thereby forming a vortex airflow and enhancing sufficient mixing and combustion of the fuel and airflow.

[0038] The burner structure 30 comprises a burner inner housing 31 and a burner outer housing 32. The burner outer housing 32 is arranged coaxially or parallel to the burner inner housing 31. Preferably, the burner outer housing 32 is arranged coaxially with the burner inner housing 31, so that a first gap 321 formed therebetween becomes uniform in each direction, which is advantageous for overall assembly.

[0039] Furthermore, the burner internal housing 31 can be formed in a cylindrical body 221 structure, and the burner internal housing 31 defines a first heating chamber 311. The other side of the combustion section 22 is provided to penetrate into the burner external housing 32, and one side of the burner internal housing 31 is connected to the other side of the combustion section 22. For example, as shown in FIG. 2, the right side of the combustion section 22 is provided to penetrate into the burner external housing 32, and the left end surface of the burner internal housing 31 is connected to the right end surface of the combustion section 22.

[0040] The exhaust pipe structure 40 is provided near the other side of the burner internal housing 31 away from the combustion section 22 in the axial direction, for example, near the other side of the burner internal housing 31 (the right side of the burner internal housing 31 shown in FIG. 2). A second heating chamber 44 is defined within the exhaust pipe structure 40, and the first heating chamber 311 communicates with the second heating chamber 44. As a result, after the oil-gas mixture produced in the combustion chamber 2215 of the combustion section 22 is ignited, further produced smoke gases and the like can enter the second heating chamber 44 in this order from the combustion chamber 2215 and the first heating chamber 311. The exhaust pipe structure 40 has an exhaust port 431, which communicates with the second heating chamber 44, and the opening direction of the exhaust port 431 faces away from the combustion section 22.

[0041] In addition, the opening direction of the exhaust port 431 facing away from the combustion section 22 includes cases where the normal direction of the cross section of the exhaust port 431 is parallel to the axial direction of the burner internal housing 31, cases where the normal direction of the cross section of the exhaust port 431 forms a certain acute angle with the axial direction of the burner internal housing 31 in the same projection plane, and cases where the normal direction of the cross section of the exhaust port 431 is perpendicular to the axial direction of the burner internal housing 31.

[0042] As a result, the steam atomizer 100 according to the embodiment of the present invention is provided with an exhaust pipe structure 40 in the burner internal housing 31, with the second heating chamber 44 of the exhaust pipe structure 40 communicating with the first heating chamber 311 of the burner internal housing 31, and with the exhaust port 431 opening away from the combustion section 22. In contrast to the related art, which typically provides a direct smoke gas exhaust port 431 in the burner internal housing 31 for vertical exhaust, which poses a relatively high risk of ignition or explosion, the provision of the exhaust pipe structure 40 allows high-temperature smoke gas, flames, etc. to be drawn out, reducing the risk of ignition or explosion and significantly improving safety and reliability. At the same time, the arrangement of the exhaust pipe provides a certain degree of buffering effect against smoke gas, thereby achieving noise reduction.

[0043] As shown in FIGS. 1 to 4 and 12 , the burner structure 30 includes a heating tube 33, which includes an internal heating tube 331. The internal heating tube 331 is installed in the first heating chamber 311, and the inlet 33111 and outlet 33121 of the internal heating tube 331 protrude from the first heating chamber 311 along the side of the burner internal housing 31 away from the combustion section 22. That is, the auxiliary agent enters the first heating chamber 311 from the outside through the inlet 33111 of the internal heating tube 331, and then is discharged from the inside of the first heating chamber 311 to the outside through the outlet 33121 of the internal heating tube 331. During this process, the oil-gas mixture formed by mixing the fuel and air stream is ignited inside the first heating chamber 311, thereby heating the auxiliary agent passing through the internal heating tube 331 inside the first heating chamber 311.

[0044] 2, an external heating pipe 332 is provided within the first gap 321, forming a preheat chamber. The inlet 33111 of the external heating pipe 332 is connected to the auxiliary agent tank 64 of the steam atomizer 100, and the outlet 33121 of the external heating pipe 332 is connected to the inlet 33111 of the internal heating pipe 331. That is, the auxiliary agent in the auxiliary agent tank 64 first enters the external heating pipe 332 and is preheated in the preheat chamber of the external heating pipe 332 by the preheat from the first combustion chamber 2215. The auxiliary agent then enters the internal heating pipe 331 from the external heating pipe 332 and is further heated in the first heating chamber 311 before being discharged from the internal heating pipe 331. Here, the burner outer housing 32 serves as a burn prevention mechanism, preventing users from being burned by direct contact with the external heating pipe 332. Meanwhile, the external heating pipe 332 simplifies the sealing structure and reduces the possibility of auxiliary agent leakage.

[0045] As a result, the burner structure 30 of the steam atomizer 100 according to the embodiment of the present invention has an external heating tube 332 disposed inside the first gap 321, which forms a preheat chamber, thereby preheating the auxiliary agent using the preheated heat inside the first heating chamber 311, and then further heating it using the internal heating tube 331, thereby effectively improving fuel utilization efficiency, saving fuel, and improving the uniformity of heating of the auxiliary agent. Furthermore, the two-layer housing structure can further improve safety and reliability.

[0046] 2 to 4 and 12, in some embodiments of the present invention, the external heating pipe 332 is installed in close contact with the outer wall of the burner internal housing 31 along the axial direction, so that the heat inside the first heating chamber 311 of the burner internal housing 31 is conducted to the external heating pipe 332 through the outer wall of the burner internal housing 31, further heating the auxiliary agent inside the external heating pipe 332, improving the thermal efficiency of the fuel and thereby achieving the effect of fuel saving. At the same time, the complete combustion of the fuel can further reduce smoke gas emissions and reduce pollution.

[0047] In some examples, as shown in Figures 2 to 4, the external heating tube 332 forms an external coil tube, which is spirally attached to the outer wall of the burner internal housing 31 along the axial direction of the burner internal housing, and the spiral structure increases the time for the auxiliary agent to pass through the external coil tube, further improving the preheating effect.

[0048] Alternatively, in order to ensure the time for the auxiliary agent to pass through the external coil tube, enhance the preheating effect, and increase the heat conduction efficiency of the first heating chamber 311, the axial distance between any two adjacent spiral coil bodies in the external coil tube is 20 mm or less, and the tube diameter of the external coil tube is 4 mm to 6 mm.

[0049] In some other examples of the present invention, the external heating pipe 332 is a heating flat pipe, which is formed into a cylindrical hollow structure extending along the axial direction and fitted onto the outer wall of the burner internal housing 31. Preferably, the cylindrical hollow heating flat pipe is coaxial with the burner internal housing 31, so that the radially inner surface of the cross section of the heating flat pipe is in close contact with the radially outer wall of the burner internal housing 31, which further improves the efficiency of heat transfer from the burner internal housing 31 to the inside of the heating flat pipe; further, the use of a cylindrical hollow flat pipe structure can also reduce the volume occupied by the external heating pipe 332.

[0050] In some other examples of the present invention, the external heating pipe 332 may be a plurality of heating flat pipes, in order to ensure heat transfer efficiency while further reducing volume and simplifying assembly. Each heating flat pipe is formed into an arc-shaped hollow structure extending along the axial direction, and the plurality of heating flat pipes are closely attached to the outer wall of the burner internal housing 31 along the circumferential direction. For example, the cross section of each heating flat pipe may be formed into a 90-degree arc, and four heating flat pipes are sequentially attached to the outer wall of the burner internal housing 31 along the circumferential direction to cover the inside of the burner internal housing 31.

[0051] Furthermore, in some examples, the external heating tube 332 is a plurality of heating flat pipes, and the circumferential spacing of the burner inner casing 31 between any two adjacent heating flat pipes is 10 mm or less, thereby facilitating assembly while ensuring conduction efficiency.

[0052] In some examples, in order to facilitate sealing of the preheat chamber and improve the appearance effect, the cover plate 34 has an external protrusion 621 that protrudes radially from the burner internal housing 31, and the dimensional difference between the radial dimension of the combustion section housing 21 and the radial dimension of the burner internal housing 31 is equal to the radial protrusion dimension of the external protrusion 621 corresponding to the axial direction.

[0053] In some examples, to facilitate sealing of the preheat chamber and improve the appearance effect, the cover plate 34 has an external protrusion 621 that protrudes radially from the burner internal housing 31, and the radial outer surface of the burner external housing 32 is flush with the radial outer surface of the combustion section housing 21.

[0054] As shown in FIGS. 2 to 4 , in some embodiments of the present invention, the exhaust pipe structure 40 includes an exhaust pipe having a connecting portion 41 connected to the burner internal housing 31. The axial direction of the connecting portion 41 and the axial direction of the burner internal housing 31 intersect on the same projected plane. For example, the two may be perpendicular to each other when projected onto the plane on which the axis of the connecting portion 41 exists, or they may form a certain angle when projected onto the plane on which the axis of the connecting portion 41 exists, with the included angle facing away from the combustion section 22. This allows the second combustion chamber 2215 to communicate with the first combustion chamber 2215 through the connecting portion 41, and further directs the smoke and flame inside the first combustion chamber 2215 along a predetermined path. At the same time, compared to related art in which an exhaust port 431 is directly provided in the burner internal housing 31, the presence of the connecting portion 41 prevents the smoke and flame from directly backflowing into the first heating chamber 311, thereby reducing the risk of burns.

[0055] 2 to 4, in a further embodiment of the present invention, the exhaust pipe further includes a reduced diameter portion 42 and a curved portion 43. One end of the reduced diameter portion 42 is connected to the connecting portion 41, and one end of the curved portion 43 is connected to the other end of the reduced diameter portion 42. The other end of the curved portion 43 faces away from the combustion section 22 and forms an exhaust port 431. Here, the radial dimension of the one end of the reduced diameter portion 42 connected to the connecting portion 41 is larger than the radial dimension of the other end connected to the curved portion 43. This utilizes the reduced diameter portion 42 to further buffer exhaust gases such as smoke gases, thereby playing a role in reducing exhaust gas emissions and noise.

[0056] As shown in FIG. 2, in some examples, in order to further improve the buffering effect of the exhaust gas and reduce obstructions in the exhaust gas flow process, the inner diameter of one end of the reduced diameter section 42 is equal to the inner diameter of the connecting portion 41, and the inner diameter of the other end of the reduced diameter section 42 is equal to the inner diameter of one end of the curved section 43.

[0057] Preferably, the outer diameter of one end of the reduced diameter portion 42 is equal to the outer diameter of the connecting portion 41, and the outer diameter of the other end of the reduced diameter portion 42 is equal to the outer diameter of one end of the curved portion 43, thereby ensuring the overall appearance of the steam atomizer 100.

[0058] As shown in Figures 2 to 4, in some examples, the axial direction of the other end of the curved portion 43 is parallel to the axial direction of the burner internal housing 31, so that the exhaust port 431 faces away from the combustion section 22, further preventing the possibility of smoke gases, flames, etc. causing burns to the operator.

[0059] In some embodiments, to enhance the noise reduction effect of the exhaust pipe structure 40, the exhaust pipe structure 40 further includes a perforated pipe and a high-temperature sound-insulating layer wrapped around the outer periphery of the perforated pipe. The perforated pipe is disposed within the exhaust pipe and may be arranged coaxially with the exhaust pipe, for example. A radial gap is formed between the perforated pipe and the exhaust pipe, and the high-temperature sound-insulating layer is disposed within the gap.

[0060] In some examples, the high-temperature sound-insulating layer may be porous glass fiber, whereby the exhaust gas forms a vortex and enters the glass fiber through the holes in the perforated pipe, using the glass fiber to absorb pressure waves while not interfering with the exhaust gas's discharge, thereby further reducing noise under conditions where the exhaust gas can be discharged normally.

[0061] In some other examples, the exhaust pipe structure 40 includes multiple baffle plates spaced apart within the exhaust pipe along the extension direction of the exhaust pipe, whereby the airflow is reflected by the multiple baffle plates internally, and finally the shock wave energy is exhausted and exits again through the outlet 33121, thereby reducing noise.

[0062] In some examples, the external heating pipe 332 comprises a first external heating pipe and a second external heating pipe, and the second external heating pipe is connected to the first external heating pipe. The first external heating pipe is installed in close contact with the outer wall of the burner internal housing 31 along the axial direction of the burner internal housing, and the second external heating pipe is installed in close contact with the outer wall of the exhaust pipe along the axial direction of the exhaust pipe. In this way, in addition to heating the auxiliary agent using thermal conduction in the first heating chamber 311, heating is also performed using thermal conduction in the second heating chamber 44, which further improves thermal efficiency and saves fuel consumption.

[0063] In some examples, the second external heating pipe and the internal heating pipe 331 are connected via a joint, which is made of a high-temperature resistant metallic material.

[0064] In some examples, the second external heating pipe is an external coiled pipe and is spirally attached to the outer wall of the exhaust pipe along the axial direction of the exhaust pipe, or the second external heating pipe is a heating flat pipe and is attached to the outer wall of the exhaust pipe along the axial direction of the exhaust pipe, thereby utilizing the external coiled pipe structure to lengthen the time it takes for the additive to pass through the exhaust pipe, and utilizing the heating flat pipe structure to increase the contact area between the additive and the outer wall of the exhaust pipe, thereby further utilizing residual heat and improving thermal efficiency.

[0065] In some examples, the second external coil tube is spirally attached to the outer wall of the exhaust pipe along the axial direction of the exhaust pipe. For example, the second external coil tube may be spirally attached to the connecting portion 41, or the second external coil tube may be spirally attached to the connecting portion 41 and the reduced diameter portion 42.

[0066] Preferably, the first external heating pipe and the second external heating pipe are integrally formed, thereby reducing the number of connecting parts and simplifying the overall structure.

[0067] 2 and 12 , the internal heating tube 331 is an inner coiled tube assembly, which includes a straight heating tube section 3311 and a coiled tube section 3312 connected thereto. The straight heating tube section 3311 extends from the outside to the inside of the first heating chamber 311 along the axial direction of the burner internal housing 31, and the coiled tube section 3312 extends spirally from the inside to the outside of the first heating chamber 311 along the axial direction of the straight heating tube section 3311, with the straight heating tube section 3311 wrapped around the inside of the coiled tube section 3312. This structural design of the straight heating tube section 3311 and the coiled tube section 3312 can further lengthen the time it takes for the auxiliary agent to pass through the first combustion chamber 2215. Furthermore, this design allows the inlet 33111 and the outlet 33121 of the inner coiled tube assembly to be located on the same side, which is advantageous for the overall structural layout.

[0068] 2 and 12 , in some examples, the coiled pipe section 3312 has a straight coiled pipe section to facilitate connection between the injection head 50 and the coiled pipe section 3312. The straight coiled pipe section is located at one end of the coiled pipe section 3312 away from the combustion section 22 and protrudes from the inside to the outside of the first heating chamber 311. The straight heating pipe section 3311 is connected to the preheat chamber, and the straight coiled pipe section is connected to the injection head 50.

[0069] 12, in some examples, the inner coiled tube may include a heated straight tube section 3311 and a coiled tube section 3312 connected thereto. The heated straight tube section 3311 extends from the outside to the inside of the first heating chamber 311 along the axial direction of the burner inner casing 31, and the coiled tube section 3312 extends spirally from the inside to the outside of the first heating chamber 311 along the axial direction of the heated straight tube section 3311, and is arranged so that the heated straight tube section 3311 is wrapped inside the coiled tube section 3312. In this way, the structural design of the heated straight tube section 3311 and the coiled tube section 3312 can further lengthen the time it takes for the auxiliary agent to pass through the first combustion chamber 2215. Furthermore, by adopting this design, the inlet 33111 and the outlet 33121 of the inner coiled tube assembly can both be located on the same side, which is advantageous for the overall structural layout.

[0070] As shown in FIG. 12, preferably, the axial gap between any two adjacent spiral coil bodies of the coil tube section 3312 is 10 mm or more so that the auxiliary material in the internal heating tube 331 is heated over the entire angle and the uniformity of heating is improved.

[0071] As shown in FIG. 12, in order to simplify the structure, reduce the number of parts, and at the same time improve the assembly integration, the heating straight pipe section 3311 and the coil pipe section 3312 are integrally formed.

[0072] Alternatively, in some embodiments of the present invention, in order to further avoid energy loss and increase the heat utilization rate, the burner structure 30 further includes an insulating layer. At least one of the burner inner housing 31 and the burner outer housing 32 has an insulating layer. For example, the insulating layer may be located on the inner wall of the burner inner housing 31, or the insulating layer may be located on the inner wall of the burner outer housing 32.

[0073] As shown in FIGS. 5 to 8, in some embodiments of the present invention, the combustion section 22 includes a cylindrical body 221, a combustion chamber cover 222, an evaporation net (not shown), and a combustion chamber outer casing 223.

[0074] The cylindrical body 221 has a first open opening 2213 on one side and a first through hole 2211 penetrating in the axial direction on the other side. For example, as shown in Fig. 5, the cylindrical body 221 has the first open opening 2213 on the upper side and the first through hole 2211 on the lower side. The cylindrical body 221 has a plurality of second through holes 2212 in its peripheral wall, which penetrate through the wall thickness of the cylindrical body 221 and are arranged at a distance from each other in the upper part of the cylindrical body 221 along the circumferential direction of the cylindrical body 221.

[0075] A combustion chamber cover 222 is provided to cover a first opening 2213 of the cylindrical body 221 so as to define a combustion chamber 2215 together with the cylindrical body 221. The combustion chamber cover 222 has an internal spark plug mounting hole 22221. An evaporation net is provided in the combustion chamber 2215, thereby increasing the amount of fuel vaporized when it enters the combustion chamber 2215. One side of the combustion chamber external housing 223 (the upper side of the combustion chamber external housing 223 in FIG. 5) has a second opening 2223, and the other side of the combustion chamber external housing 223 (the lower side of the combustion chamber external housing 223 in FIG. 5) has a third through-hole 2231.

[0076] Furthermore, the combustion chamber outer casing 223 is fitted onto the outside of the cylindrical body 221, and there is a predetermined gap between the inner wall of the combustion chamber outer casing 223 and the outer wall of the cylindrical body 221. The projection of the first through hole 2211 onto the plane in which the third through hole 2231 exists falls within the range of the third through hole 2231.

[0077] As a result, the steam sprayer 100 according to an embodiment of the present invention defines a combustion chamber 2215 using a cylindrical body 221 and a combustion chamber cover 222, provides a second through hole 2212 in the cylindrical body 221 that communicates with the combustion chamber 2215, and fits the combustion chamber external casing 223 onto the outside of the cylindrical body 221, leaving a predetermined gap between the cylindrical body 221 and the combustion chamber external casing 223. By providing a predetermined gap between the combustion chamber external casing 223 and the cylindrical body 221 and multiple circumferentially arranged second through holes 2212 on the cylindrical body 221, the airflow introduced by the blower section 10 of the steam sprayer 100 can form a vortex airflow within the combustion chamber 2215. At the same time, by making the first through hole 2211 fall within the range of the third through hole 2231 on the plane on which the third through hole 2231 of the combustion chamber external casing 223 exists, and by utilizing the structure of the combustion chamber external casing 223 to connect the entire combustion section 22 to the combustion section casing 21 and the burner structure 30, the entire combustion section 22 can be easily attached to the combustion section casing 21 of the steam atomizer without affecting the oil-gas mixture from entering the burner structure 30 of the steam atomizer through the first through hole 2211 and the third through hole 2231, and the overall volume occupation can be reduced.

[0078] As shown in Figures 5 to 8, in some examples of the present invention, the bottom of the cylindrical body 221 has a cover plate 34 of the cylindrical body 211, and the first through hole 2211 is provided in the center of the cylindrical cover plate, so that the vortex oil-gas mixture in the combustion chamber 2215 is introduced into the burner internal casing 31 of the burner structure 30 through the first through hole 2211 and the third through hole 2231, and further heats the inner coil tube inside the first heating chamber 311 of the burner internal casing 31.

[0079] As shown in FIGS. 5 to 8 , in some examples of the present invention, the combustion chamber cover 222 includes a cover body 2221 and a cover shroud 2222. The cover shroud 2222 is connected to the outer periphery of the cover body 2221 and is disposed so as to surround the cover body 2221. For example, in FIG. 4 , the cover shroud 2222 is disposed below the outer periphery of the cover body 2221. The cover shroud 2222 is further provided with an internal spark plug mounting hole 22221. When the combustion section 22 is assembled into the combustion section housing 21 of the steam atomizer, the internal spark plug mounting hole 22221 on the cover shroud 2222 corresponds to the position of the external spark plug mounting hole on the combustion section housing 21, thereby facilitating the spark plug 90 to pass through the external spark plug mounting hole and the internal spark plug mounting hole 22221, in that order, and protrude into the combustion chamber 2215.

[0080] 5 to 8 , in some embodiments of the present invention, a first flange 2214 is provided on the upper edge of the side wall of the cylindrical body 221, and is configured to extend upward along the axial direction of the cylindrical body 221 and curve outward along the radial direction of the cylindrical body 221. Preferably, the first flange 2214 extends upward along the axial direction of the cylindrical body 221 and curve outward along the radial direction of the cylindrical body 221, and the bent portion of the first flange 2214 transitions in an arc shape. Similarly, a second flange 2224 is provided on the lower edge of the side wall of the cover shroud 2222, and is configured to extend downward along the axial direction of the cover shroud 2222 and curve outward along the radial direction of the cover shroud 2222. Preferably, the second flange 2224 extends downward along the axial direction of the cover shroud 2222 and outward along the radial direction of the cover shroud 2222, and the bent portion of the second flange 2224 transitions in an arc shape, which facilitates welding between the combustion chamber cover 222 and the cylindrical body 221 and ensures the tightness and reliability of the connection between them.

[0081] 5 to 8, in some examples, the other side of the cylindrical body 221 (the lower side of the cylindrical body 221 in FIG. 1) is connected to the other side of the combustion chamber external housing 223 (the lower side of the combustion chamber external housing 223 in FIG. 5), and the two are provided coaxially. This, on the one hand, makes it more advantageous to form a vortex airflow by utilizing the circumferential uniformity of a predetermined gap formed between the two, and on the other hand, it is also advantageous to communicate between the first through hole 2211 and the third through hole 2231, so that the vortex mixture can pass through the first through hole 2211 and the third through hole 2231 from the combustion chamber 2215 and enter the inside of the first heating chamber 311 of the burner structure 30.

[0082] 5, in some examples, the combustion chamber outer housing 223 has a housing cover plate 34, and the third through-hole 2231 is provided in the center of the housing cover plate, which facilitates connection between the combustion chamber outer housing 223 and the cylindrical body 221.

[0083] Preferably, in some examples, the first through-hole 2211 and the third through-hole 2231 are arranged coaxially and have the same size, as shown in Fig. 5, which can ensure the passage of the swirling oil-gas mixture and utilize the remaining space on the other side of the combustion chamber outer casing 223 and the remaining space on the other side of the cylinder 221 to achieve a tight connection between them.

[0084] In another embodiment of the present invention, a plurality of fourth through holes are provided in the peripheral wall of the cover shroud 2222, and the plurality of fourth through holes are spaced apart along the circumferential direction of the cover shroud 2222. This allows the airflow introduced by the blower 10 to pass through the fourth through holes, the predetermined gap, and the second through hole 2212 into the combustion chamber 2215, forming a vortex airflow, which is further advantageous for sufficient mixing of the oil and gas.

[0085] 5 to 8, in some embodiments, a third flange 2232 is provided on the upper edge of the side wall of the combustion chamber external housing 223, and the third flange 2232 is configured to extend in a curved manner upward along the axial direction of the combustion chamber external housing 223 and outward along the radial direction. Preferably, the third flange 2232 extends upward along the axial direction of the combustion chamber external housing 223 and outward along the radial direction, with a smooth transition at the bent portion. This makes the plane on which the edge of the third flange 2232 exists perpendicular to the axial direction of the combustion chamber external housing 223, further facilitating the connection between the combustion chamber external housing 223 and the combustion unit housing 21 and the burner external housing 32.

[0086] Preferably, the predetermined gap is 5 mm to 15 mm, as shown in Figure 5. If the predetermined gap is less than 5 mm, it is not favorable for the airflow introduced by blower unit 10 to pass through the predetermined gap and second through-hole 2212 into combustion chamber 2215 and form a vortex. On the other hand, if the predetermined gap is more than 15 mm, the space of combustion chamber 2215 becomes relatively small, which reduces the volume of the oil-gas mixture in combustion chamber 2215 and also is not favorable for the formation of a vortex.

[0087] 5, in some examples, the cover body 2221 has a fuel pipe 22211 that communicates with the combustion chamber 2215. Fuel in the fuel tank 63 can be introduced into the combustion chamber 2215 via this fuel pipe 22211.

[0088] 5, in some examples, the combustion chamber outer casing 223 forms a cylindrical structure as a whole, and the cross section of the third flange 2232 forms a ring structure, which can further reduce the volume occupied and the weight of the entire equipment compared to related art that uses a rectangular combustion section 22.

[0089] As shown in Figures 1 and 2, in some embodiments of the present invention, in order to facilitate assembly of the exhaust pipe structure 40, the burner internal housing 31 has an external protrusion that protrudes from the burner external housing 32 in the axial direction, and the exhaust pipe structure 40 is provided on the external protrusion, or the burner external housing 32 is provided with an avoidance portion, and the exhaust pipe structure 40 passes through and exits through the avoidance portion.

[0090] In some examples, the burner outer casing 32 is made of a heat insulating material to ensure the heat quantity in the second heating chamber 44 and reduce heat loss. Meanwhile, in other examples, the burner outer casing 32 is provided with a plurality of heat dissipation holes arranged along the circumferential direction to reduce the heat quantity loss in the second heating chamber 44 and at the same time prevent the burner outer casing 32 from overheating.

[0091] As shown in Figures 1, 2 and 3, in some embodiments of the present invention, the blower 10 is an axial fan assembly or a casing 12 fan assembly. The blower 10 is configured to generate a wind pressure of 800 Pa or more in the intake passage. Setting the wind pressure in the intake passage makes it easier to generate a vortex flow in the combustion chamber 2215, which is beneficial to the complete combustion of the oil-gas mixture and reduces exhaust gas emissions, while also reducing noise while reducing exhaust gas emissions.

[0092] In some examples, as shown in FIGS. 13 to 15 , the axial fan assembly includes an intake pipe 15, a drive unit 14, and an axial fan. The drive unit 14 may be a drive motor. A mounting seat 18 is provided at one end of the intake pipe 15. The mounting seat 18 has a generally cylindrical structure and at least a portion of it protrudes into the intake pipe 15. A ventilation gap is provided between the mounting seat 18 and the inner wall of the intake pipe 15, and a guide vane may be provided in the ventilation gap. The ventilation gap forms the air outlet 11. The drive unit 14 is attached to the mounting seat 18 and has a rotating shaft 141 extending along the axial direction of the intake pipe 15. The axial fan is rotatably provided at the other end of the intake pipe 15 and is connected to the rotating shaft 141 and driven to rotate by the drive unit 14. Here, the operating wind pressure in the intake pipe 15 is 800 Pa or more.

[0093] Furthermore, the axial fan includes a hub 161 and a plurality of vortex fan blades 162. The hub 161 is connected to the rotating shaft 141. The plurality of vortex fan blades 162 are spaced apart along the circumferential direction of the hub 161, and each vortex fan blade 162 is located between the intake pipe 15 and the hub 161.

[0094] This allows the drive unit 14 to be located at the rear end of the mounting seat 18 by using an axial fan assembly, thereby reducing the direct effect of the intake airflow to some extent. On the other hand, the axial fan also facilitates the connection between the blower unit 10 and the combustion unit housing 21, reducing the volume occupied.

[0095] As shown in FIGS. 1 to 4, in another embodiment of the present invention, a casing 12 fan assembly includes a casing 12 and a corrosion-resistant high-pressure assembly 13. The corrosion-resistant high-pressure assembly includes a drive unit 14 and an impeller (not shown). A first mounting chamber and a second mounting chamber are defined within the casing 12, spaced apart from each other. The casing 12 has an air intake port 121 and an air outlet 11 communicating with the second mounting chamber. The drive unit 14 is provided in the first mounting chamber, and the impeller is provided in the second mounting chamber. A drive shaft of the drive unit 14 extends from the first mounting chamber to the second mounting chamber and is connected to the impeller to drive the impeller, drawing air from the air intake port 121 into the second mounting chamber and introducing it into the intake passage via the air outlet 11. As a result, the separated first and second mounting chambers allow the drive unit 14 to be separated from the impeller, and corrosion and damage to parts due to the second mounting chamber, the air outlet 11 connected to it, the air flow in the intake passage, and the backflow of the oil-gas mixture can be avoided.

[0096] 13 to 15, in some embodiments, the blower 10 further includes a filter 17 to reduce damage to components due to impurities in the airflow. The filter 17 is provided in the air intake path of the blower 10 and is located upstream of the air intake passage.

[0097] As shown in FIG. 15 , in some examples, the blower unit 10 is an axial fan assembly, and the filter 17 includes a connecting plate 171, a tubular body 173, a fixing plate 172, and multiple filter plates 174. The connecting plate 171 is connected to one side of the combustion unit housing 21. A through-hole is provided in the center of the connecting plate 171, and the position of the through-hole corresponds to the position of the intake passage. The tubular body 173 is provided to pass through the through-hole. One end of the intake pipe 15 facing away from the mounting seat 18 is provided to pass through the tubular body 173. The fixing plate 172 is provided spaced apart from the connecting plate 171 in the axial direction of the tubular body 173, and is connected to the lower end surface of the tubular body 173. Multiple filter plates 174 are provided along the outer periphery of the tubular body 173 at intervals between the connecting plate 171 and the fixing plate 172. Here, the axial flow fan is spaced apart from the fixed plate 172 in the axial direction.

[0098] As shown in FIGS. 1, 5, and 9 to 11, in some embodiments of the present invention, the combustion section 22 has a fuel pipe 22211. For example, as shown in FIG. 5, the fuel pipe 22211 can be provided in the combustion chamber cover 222 of the combustion section 22. The combustion section housing 21 has an oil supply hole through which the fuel pipe 22211 passes. The oil supply hole is located on the other side of the combustion section housing 21 opposite to its open side, for example, on the left side in FIG. 2. The steam atomizer 100 further includes a box assembly 60 and an injection head 50. The box assembly 60 includes a fuel tank 63, an auxiliary agent tank 64, and a chemical agent tank 62. The fuel tank 63 is connected to the combustion section 22 via the fuel pipe 22211. The auxiliary agent tank 64 is connected to an inlet end 3321 of the external heating pipe 332. The inlet end 3321 can protrude radially along the peripheral wall of the burner outer housing 32. The drug reservoir 62 and the outlet 33121 of the internal heating tube 331 are both connected to the spray head 50, thereby forming a spray containing the drug.

[0099] Alternatively, a calcium magnesium ion filter 641 is provided between the auxiliary agent tank 64 and the external heating pipe 332. This allows the calcium magnesium ion filter 641 to filter out calcium magnesium ions in the auxiliary agent, thereby reducing calcium magnesium precipitation in the steam atomizer 100.

[0100] 1 to 3, in some embodiments, the device further includes a handle portion 80, one end of which is connected to the combustion unit housing, making it easier for the user to grip.

[0101] As shown in FIGS. 1 and 9 to 11, in some examples, the box assembly 60 further includes a box housing 61. The box housing 61 defines a box structure with one side open, and the box structure is generally rectangular. The box housing 61 may be formed by a bottom housing and a housing shroud surrounding the edge of the bottom housing. The box structure defines a first storage chamber 611 and has an escape port 613 on one side of the box structure. For example, as shown in FIGS. 9 and 10, the escape port 613 is located at the upper edge of the top sidewall of the box housing 61. When an auxiliary agent tank 64 is attached to the first storage chamber 611, the auxiliary agent pipe can pass through and exit the first storage chamber 611 through the escape port 613. The fuel tank 63 and the chemical tank 62 are attached horizontally in parallel to each other above the box structure and are each lockably connected to the box structure. At the same time, the other side wall of the box structure adjacent to the side wall where the escape port 613 is located is recessed inward to form a second storage chamber 612, which can accommodate structures such as a power supply 71, a pump body 72, a control system 73, etc.

[0102] 9 to 11, in some examples, one side wall of the fuel tank 63 and the drug tank 62 has a protrusion 621, and the other side wall has a recess 632 that fits with the protrusion 621. When the fuel tank 63 and the drug tank 62 are attached to the top of the box housing 61, the protrusion 621 fits with the recess 632, thereby further increasing the tightness of the connection, ensuring an appearance effect, and improving the overall integration.

[0103] In some examples, the vapor atomizer 100 includes a spark plug 90. The combustion section 22 has an internal spark plug mounting hole 22221. The combustion section housing 21 has an external spark plug mounting hole corresponding to the position of the internal spark plug mounting hole 22221. The spark plug 90 is disposed to pass through the external spark plug mounting hole and the internal spark plug mounting hole 22221 in sequence, and at least a portion of the spark plug 90 is located within the combustion chamber 2215 of the combustion section 22. The vapor atomizer 100 further includes a power source 71, a pump body 72, and a control system 73. The power source 71, the pump body 72, and the control system 73 are all disposed within the second containing chamber 612. The power source 71 is connected to the pump body 72, the blower 10, and the spark plug 90, respectively. The control system 73 is connected to the spark plug 90, the blower 10, and the pump body 72, respectively, and controls the spark plug 90, the blower 10, and the pump body 72. In this way, the mutually isolated first storage chamber 611 and second storage chamber 612 are used to respectively mount the drug tank 62, auxiliary agent tank 64, and fuel tank 63, as well as the power supply 71, pump body 72, and control system 73, thereby improving the overall integration level and preventing the drug tank 62, auxiliary agent tank 64, and fuel tank 63 from being unexpectedly damaged or leaking and infiltrating the power supply 71 and control system 73, causing a major risk to use.

[0104] In some embodiments, the fuel tank 63 is provided with a fuel pump 631. The control system 73 includes an electronic injection ignition module and a solenoid valve 633. The outlet end of the fuel pump 631 is connected to the fuel pipe 22211 via the solenoid valve 633. Here, the electronic injection ignition module is connected to the spark plug 90, the blower 10, and the solenoid valve 633, respectively, to control the ignition and operation stages of the vapor atomizer 100.

[0105] Furthermore, when the vapor atomizer 100 is in the ignition stage, the electronic injection ignition module controls the solenoid valve 633 to be at a first opening degree and the blower 10 to be at a first wind pressure or a first wind speed.

[0106] When the vapor atomizer 100 is in the operating stage, the electronic injection ignition module controls the solenoid valve 633 to be at the second opening degree and the blower 10 to be at the second wind pressure or the first wind speed.

[0107] Here, the first opening degree is larger than the second opening degree, and the first wind pressure is smaller than the second wind pressure; the first opening degree is larger than the second opening degree, and the first wind speed is smaller than the second wind speed.

[0108] As a result, by controlling this electronic injection ignition module, during the ignition stage, the wind pressure or wind speed of the blower 10 is relatively low, the opening of the solenoid valve 633 is large, and the amount of fuel supplied is large, which is advantageous for supplying fuel into the combustion chamber 2215, and can improve the ignition speed and ignition power compared to the related art method of injecting a fixed amount of fuel using a plunger pump.

[0109] At the same time, by adopting a relatively small opening of the solenoid valve 633 during the operating stage, reducing the amount of fuel supplied and increasing the wind pressure or wind speed, it is favorable for sufficient mixing of the fuel and the vortex air flow in the combustion chamber 2215, thereby improving combustion efficiency and reducing fuel consumption and exhaust gas emissions.

[0110] 1 and 9, in some examples, the box assembly 60 further includes a sealing cover to further protect components such as the power supply 71 and the control system 73 within the second storage chamber 612. The sealing cover is removably provided over the second storage chamber 612.

[0112] In describing the present invention, a "first feature" or a "second feature" may comprise one or more of said features.

[0113] In describing the present invention, "plurality" means two or more.

[0114] In describing the present invention, a first feature being "above" or "below" a second feature can include direct contact between the first and second features, or can include contact between the first and second features that is not in direct contact but is made via another feature between them.
