[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] An oil stove in this embodiment relates to the technical field of oil stoves. By arranging the oil injection system inside the air blowing system, the oil mist is promoted to be evenly diffused under wind pressure, and the mixing state of the oil mist and air is optimized, so that the flame is more stable and the combustion efficiency is higher.

[0037] See also Figures 1 to 9 In this embodiment, a fuel stove includes a housing 100, an air supply assembly 200 and an oil supply assembly 300. The housing 100 can support and fix the various components of the fuel stove. The air supply assembly 200 is used to blow air into the fuel stove. The oil supply assembly 300 cooperates with the air supply assembly 200. The air supply assembly 200 can blow air relative to the oil supply assembly 300 to promote uniform diffusion of oil mist under wind pressure, optimize the mixing state of oil mist and air, make the flame more stable, and increase the combustion efficiency.

[0038] The top of the housing 100 is open, and the open top is arranged relative to the cookware, so that the cookware can be heated.

[0039] The air supply assembly 200 includes an air duct 210 and a ventilation hole 220. One end of the air duct 210 is detachably connected to the bottom of the shell 100. The ventilation hole 220 is opened at the bottom of the shell 100. The ventilation hole 220 connects the air duct 210 and the shell 100. The wind from the air duct 210 can be input into the shell 100 through the ventilation hole 220 to provide sufficient oxygen supply for the oil mist and promote the combustion of the oil mist.

[0040] The oil delivery assembly 300 includes an oil delivery unit 310 and a sealing unit 320. The oil delivery unit 310 includes an oil sprayer 311 and an oil delivery member 312. The oil sprayer 311 is detachably connected to the bottom of the housing 100. One end of the oil sprayer 311 extends relative to the inside of the housing 100 and can spray oil mist relative to the cooker. A plurality of ventilation holes 220 are arranged around the oil sprayer 311. The airflow sprayed from the ventilation holes 220 relative to the housing 100 can increase the wind pressure at the edge of the oil mist, promote the diffusion of the oil mist, optimize the mixing state of the oil mist and the air, make the flame more stable, and increase the combustion efficiency. The other end of the oil sprayer 311 is located in the air duct 210. The oil delivery member 312 passes through the air duct 210 and is connected to the oil sprayer 311, and can input the external fuel into the oil sprayer 311.

[0041] The sealing unit 320 is disposed between the oil delivery member 312 and the air duct 210, which can not only enhance the sealing performance between the air duct 210 and the oil delivery member 312, hinder gas leakage in the air duct 210, and prevent the wind pressure from decreasing and becoming unstable, but also hinder the relative rotation of the oil delivery member 312, and prevent the oil delivery member 312 from being abnormally loosened, causing leakage of oil mist.

[0042] In some embodiments, see Figure 2 and Figure 3 The oil delivery unit 310 also includes a mounting hole 313 and a screw-on part 314. The mounting hole 313 is opened at the bottom of the housing 100. A plurality of ventilation holes 220 are arranged around the mounting hole 313. The fuel injection part 311 is inserted into the mounting hole 313. The fuel injection part 311 is firmly installed in the mounting hole 313 and can cooperate with the ventilation hole 220 to promote the flow of air relative to the oil mist, which is beneficial to the mixing of air and fuel near the fuel injection part 311, thereby improving the mixing efficiency of fuel and air, thereby promoting the full progress of the combustion process.

[0043] As a further implementation, threads are provided on the outside of the fuel spraying member 311 , and the screw-on member 314 is threadedly connected to the fuel spraying member 311 . The screw-on member 314 is specifically a nut, which can prevent the fuel spraying member 311 from falling off the housing 100 .

[0044] In some embodiments, see 4 to Figure 6The oil delivery component 300 further includes a first connection unit 330, which is disposed between the oil injection component 311 and the oil delivery component 312. The first connection unit 330 includes a threaded hole 331 disposed on the oil injection component 311 and a threaded head 332 disposed at one end of the oil delivery component 312, and the threaded head 332 is screwed into the threaded hole 331. The connection between the oil injection component 311 and the oil delivery component 312 is tighter and more stable, and is not prone to loosening or falling off. The oil injection component 311 and the oil delivery component 312 are threadedly connected by means of the first connection unit 330, which can facilitate the disassembly and assembly of the oil delivery component 312, simplify the maintenance process of the oil injection component 311 and the oil delivery component 312, and clean up the accumulated oil dirt.

[0045] In some embodiments, see Figures 5 to 7 The oil delivery component 300 also includes a second connecting unit 340, which is arranged between the oil delivery member 312 and the air duct 210. The second connecting unit 340 includes a cylinder 341 connected to the inside of the air duct 210, and the cylinder 341 is integrally connected to the air duct 210. The oil delivery member 312 is movably inserted into the cylinder 341. The oil delivery member 312 is inserted into the air duct 210 from the cylinder 341 and is threadedly connected to the oil injection member 311. The cylinder 341 can increase the contact area with the oil delivery member 312, and the connection of the oil delivery member 312 is more firm and stable, which can prevent the connection part from loosening or falling off due to force during use, and can also provide good basic conditions for the sealing between the oil delivery member 312 and the cylinder 341.

[0046] In some embodiments, see Figures 6 to 9 The sealing unit 320 includes a sealing sleeve 321 and a gasket 322. The gasket 322 is sleeved on the oil conveying member 312. The sealing sleeve 321 is penetrated through the oil conveying member 312 and sleeved on the gasket 322. The inner wall of the sealing sleeve 321 is threadedly connected to the outer wall of the cylinder 341. The two ends of the gasket 322 are respectively abutted against the end of the cylinder 341 and the end of the sealing sleeve 321.

[0047] The inner wall of the sealing sleeve 321 is threadedly connected to the outer wall of the cylinder 341 to form a tight sealing structure. This ensures a firm connection between the sealing sleeve 321 and the cylinder 341, preventing gas from leaking from the connection. The gasket 322 is sleeved on the oil delivery member 312 to provide additional sealing support and protection. The two ends of the gasket 322 are respectively abutted against the end of the cylinder 341 and the end of the sealing sleeve 321 to form a complete sealing structure. The presence of the gasket 322 further enhances the sealing performance and prevents gas leakage.

[0048] As a further implementation, see Figure 8The sealing sleeve 321 includes a sleeve body 321a and a flange portion 321b. The flange portion 321b is arranged at the end of the sleeve body 321a and is integrally connected with the sleeve body 321a. A connecting hole 321c adapted to the oil conveying member 312 is opened on the flange portion 321b. The oil conveying member 312 is inserted into the connecting hole 321c. The flange portion 321b can abut against the end of the gasket 322 to press the gasket 322 to form a complete sealing structure, which can prevent gas leakage.

[0049] In some embodiments, see Fig. 9 The oil delivery member 312 is provided with an annular groove 323, in which the gasket 322 is engaged. The annular groove 323 on the oil delivery member 312 provides a fixed position for the gasket 322 to be installed. The presence of the annular groove 323 enables the gasket 322 to be accurately positioned and fixed, and is not easy to move or fall off, thereby ensuring the stability of the sealing structure. The gasket 322 is engaged in the annular groove 323 to form a tight connection. A firm connection is formed between the gasket 322 and the oil delivery member 312, preventing the gasket 322 from loosening or falling off due to force during use.

[0050] In some embodiments, see Figure 4 An annular flange 211 is provided at one end of the air duct 210 opposite to the shell 100. The annular flange 211 is integrally connected to the shell 100. A screw hole 212 for connecting to the shell 100 is provided on the annular flange 211. A bolt is screwed into the shell 100, and the bolt passes through the shell 100 and is connected to the screw hole 212. The connection between the air duct 210 and the shell 100 is relatively simple, and the connection can be completed through the screw hole 212 and connecting tools such as screws, which simplifies the installation and maintenance process.

[0051] In some embodiments, see Figure 1 A fuel stove also includes a dual ignition system 400, which includes an ignition pin 410 and a mounting hole 420 opened on the housing 100. The two ignition pins 410 are respectively installed in the two mounting holes 420. The two ignition pins 410 simultaneously emit arcs relative to the stove body to ignite. If any one of the ignition pins 410 is damaged, the other ignition pin 410 can still work normally. The system has higher stability and better safety.

[0052] Working process: First, insert the oil injection part 311 into the mounting hole 313, and fix the oil injection part 311 on the housing 100 by using the screw-on part 314. Then, use bolts to connect the annular flange 211 to the housing 100. Next, sequentially sleeve the sealing sleeve 321 and the gasket 322 on the oil delivery part 312. Insert the oil delivery part 312 from the cylinder 341 into the air guide 210, and connect the threaded head 332 of the oil delivery part 312 with the threaded hole 331 of the oil injection part 311. Finally, screw the sealing sleeve 321 onto the cylinder 341 to hinder the relative rotation of the oil delivery part 312 and prevent the oil delivery part 312 from being abnormally loosened, causing air leakage.

[0053] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto.
