[0024] The utility model is further explained in connection with the drawings and examples.

[0025] Please refer to Figures 1-6The utility model provides a kind of embodiment: high-efficiency combustion-supporting fire increasing device, including fuel tank 1;Still including atomizer 3 and venturi mixer main body 9, the inside of fuel tank 1 is slidably connected with float 2 by guide rod, the middle of float 2 is fixedly connected with atomizer 3, and float 2 is penetrated by atomizer 3, the front end of fuel tank 1 is fixedly connected with filler port 4, the upper end of fuel tank 1 is fixedly connected with vapour reserve box 5, vapour reserve box 5 inside front end is embedded with gas sensor 6, the rear end of vapour reserve box 5 is fixedly connected with first one-way air valve 7, the upper end of vapour reserve box 5 is fixedly connected with venturi mixer suction pipe 8, the upper end of venturi mixer suction pipe 8 is fixedly connected with venturi mixer main body 9, one side of venturi mixer main body 9 is fixedly connected with second one-way air valve 10, one side of second one-way air valve 10 is fixedly connected with air pump 11, after liquid fuel is added in fuel tank 1 from filler port 4, float 2 makes atomizer 3 float up, then pass threaded plug and stop filler port 4, and open atomizer 3 and send liquid fuel into vapour reserve box 5 upwards to atomize, so that the contact area of atomized liquid fuel and air increases, so that atomized liquid fuel is more easily changed into steam, simultaneously start air pump 11 and inject air into venturi mixer main body 9, air in venturi mixer main body 9 will experience a period of flow rate increase and pressure decreases, to form negative pressure in venturi mixer suction pipe 8, and fuel steam and mist drop in vapour reserve box 5 are sucked into venturi mixer main body 9, and air from first one-way air valve 7 into vapour reserve box 5 due to negative pressure is sucked into venturi mixer main body 9, so that fuel steam is mixed with air fully before being ignited, to greatly increase the temperature when flame burns, and the working principle of venturi mixer main body 9 is prior art, not repeated here.

[0026] Please refer to Figures 4-6In this embodiment, a diversion pipe assembly 12 is fixedly connected to the other side of the Venturi mixer body 9. Multiple threaded pipes 13 are provided within the diversion pipe assembly 12. Fuel vapor and small droplets are fully mixed with air within the Venturi mixer body 9 and then enter the diversion pipe assembly 12, flowing into the multiple threaded pipes 13. This allows the gaseous fuel to spiral forward within the threaded pipes 13, reducing internal gas eddies and improving the stability of the airflow and flame shape. Subsequently, the gaseous fuel passes through the copper mesh flame arrester 19 and reaches the outside, where it can be ignited by the user using an ignition tool. A heat transfer frame 14 is fixedly connected to the outside of the diversion pipe assembly 12. A heat exchange duct 15 is provided at the lower end of the heat transfer frame 14. Multiple heat absorption plates 16 are fixedly connected within the heat exchange duct 15, and an exhaust fan 17 is fixedly connected to the rear end of the heat exchange duct 15. The exhaust fan 17 is used to ventilate the heat exchange duct. A negative pressure is generated in the heat exchange duct 15 and the exhaust gas return suction cup 20 to draw the heated air around the flame into the heat absorption plate 16 through the suction port 21 to heat the heat exchange duct 15 and the heat conduction frame 14. The heat exchange duct 15 then preheats the mixed gas in the threaded pipe 13 through heat conduction, which intensifies the molecular movement in the mixed gas and makes the contact between fuel and oxygen more complete, thereby further improving the combustion efficiency and combustion stability. An insulation sleeve 18 is fixed to the outside of the heat conduction frame 14. A copper mesh flame arrester 19 is embedded in one side of the diversion pipe group 12. The copper mesh flame arrester 19 is used to prevent the flame from spreading into the diversion pipe group 12 and the threaded pipe 13. An exhaust gas return suction cup 20 is fixed to one side of the heat exchange duct 15. Multiple suction ports 21 are opened on the side end face of the exhaust gas return suction cup 20. The side end face of the suction port 21 is fixed to the diversion pipe group 12.

[0027] In use, after adding liquid fuel into the fuel tank 1 through the filling port 4, the float ring 2 causes the atomizer 3 to float. Then, the filling port 4 is blocked by the threaded plug, and the atomizer 3 is turned on to atomize the liquid fuel and send it upward into the vapor pre-reservation box 5. This increases the contact area between the atomized liquid fuel and the air, making it easier for the atomized liquid fuel to turn into vapor. At the same time, the air pump 11 is started to inject air into the Venturi mixer body 9. The air in the Venturi mixer body 9 will undergo a process of increased flow rate and decreased pressure, thereby creating a negative pressure in the Venturi mixer suction pipe 8, which draws the fuel vapor in the vapor pre-reservation box 5 into the Venturi mixer body 9. The air that enters the vapor pre-reservation box 5 from the first one-way air valve 7 due to the negative pressure is also drawn into the Venturi mixer body 9. This allows the fuel vapor to be fully mixed with the air before being ignited, thereby greatly increasing the temperature during flame combustion. The working principle of the Venturi mixer body 9 is existing technology and will not be described in detail here.

[0028] Fuel vapor and droplets are fully mixed with air in the Venturi mixer body 9 and then enter the diversion pipe group 12 and flow into multiple threaded pipes 13 to allow the gasified fuel to spiral forward in the threaded pipes 13, thereby reducing the eddy currents inside the gas and improving the stability of the airflow and flame shape. Subsequently, the gasified fuel passes through the copper mesh flame arrester 19 and comes to the outside, where the user can ignite it with an ignition tool.

[0029] The exhaust fan 17 is used to generate negative pressure in the heat exchange duct 15 and the exhaust gas return suction cup 20, so as to draw the heated air around the flame into the heat absorption plate 16 through the suction hole 21 to heat the heat exchange duct 15 and the heat conduction frame 14. The heat exchange duct 15 then preheats the mixed gas in the threaded pipe 13 through heat conduction, which intensifies the molecular movement in the mixed gas and makes the contact between fuel and oxygen more complete, so as to further improve the combustion efficiency and further improve the combustion stability. The copper mesh flame arrester 19 is used to prevent the flame from spreading into the diversion pipe group 12 and the threaded pipe 13.

[0030] Through the above steps, by setting up the atomizer 3 and the Venturi mixer body 9, the liquid fuel is atomized, making it easier for the atomized liquid fuel to turn into vapor. The fuel vapor in the vapor pre-reservoir box 5 is drawn into the Venturi mixer body 9 by the air pump 11 and the Venturi mixer body 9 and fully mixed with air, thereby significantly increasing the fuel combustion efficiency and the temperature during flame combustion. Furthermore, by setting up the heat conduction frame 14 and the exhaust gas return suction plate 20, the mixed gas in the Venturi mixer body 9 enters the diversion pipe group 12 and then flows into multiple threaded pipes 13, so that the gasified fuel spirals forward in the threaded pipes 13, thereby reducing the eddy currents inside the gas, improving the stability of the airflow and flame shape, and recovering the heated air around the flame to preheat the mixed gas in the threaded pipes 13, thereby further improving the combustion efficiency and combustion stability.
