DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 5 In an embodiment of the utility model, an air pump type new energy fuel stove includes a stove body 1, a fuel tank 2 for storing fuel and an air supply pump 3 for spraying the fuel after vaporization. A stove head 4 is installed on the top of the stove body 1, an outer fire cover 5 is provided below the stove head 4, and a plurality of fire holes 6 are provided on the upper side of the outer fire cover 5. A fuel vaporization component is installed inside the stove body 1, and the fuel vaporization component includes a vaporization chamber 21 located inside the stove body 1, and a fuel injection component is installed on the top of the vaporization chamber 21, and an igniter 7 for igniting the vaporized fuel is installed inside the outer fire cover 5.

[0024] The stove head 4 is installed on the stove body 1, the outer fire cover 5 is installed below the stove head 4, and the fire hole 6 is opened on the outer fire cover 5. The fuel vaporization component can change the fuel from liquid to mist oil droplets or gas, which can increase the contact area with the air and make the combustion more complete. The vaporization chamber 21 can provide a space for the coexistence of fuel and air, which is convenient for the vaporization and atomization of the fuel. The nozzle assembly can conveniently spray the fuel. The air supply pump 3 and the igniter 7 can be purchased directly from the market. The igniter 7 can ignite the vaporized fuel, which is convenient for the use of the fuel stove.

[0025] In one embodiment, specifically, the fuel injection assembly includes an oil pump 8 located inside the fuel tank 2, the output end of the oil pump 8 is connected to a fuel supply pipe 9, the other end of the fuel supply pipe 9 is connected to a fuel injection bin 10, the fuel injection bin 10 is wide at the top and narrow at the bottom, a plurality of fuel injection micropores 11 are provided at the bottom of the fuel injection bin 10, a separation column 12 is installed inside the fuel injection bin 10, a gap for forming an oil film is provided between the fuel injection bin 10 and the separation column 12, a cavity 13 is formed inside the separation column 12, the cavity 13 is connected to the air supply pump 3, a plurality of jet holes 14 cooperating with the fuel injection micropores 11 are provided on the side wall of the separation column 12, the fuel injection micropores 11 are in the shape of a venturi tube, and the jet holes 14 are in the shape of a cone, the oil pump 8 can be purchased directly from the market, and the oil pump 8 and the fuel supply pipe 9 are connected. In addition, the fuel injection tank 10 is located at the top of the vaporization chamber 21, and the fuel injection micropores 11 are opened at the bottom of the fuel injection tank 10. The number of fuel injection micropores 11 is multiple, and the number of fuel injection tanks 10 can also be multiple. The fuel injection tank 10, which is wide at the top and narrow at the bottom, can facilitate the inflow of fuel. The separation column 12 can form a thinner oil film between the fuel injection tank 10, and the jet hole 14 is opened at the bottom of the separation column 12. The jet hole 14 is arranged opposite to the fuel injection micropores 11. The conical jet hole 14 can facilitate gas acceleration, and the venturi-shaped fuel injection micropores 11 can facilitate the vaporization and atomization of fuel. More specifically, a filter 20 is installed on the fuel supply pipe 9. The filter 20 can be purchased directly from the market, and can filter the fuel entering the fuel injection tank 10 to avoid clogging of the fuel supply pipe 9 and the fuel injection micropores 11 on the fuel injection tank 10.

[0026] Among them, the fuel injection tank 10 is provided with an oil inlet pipe 15, the fuel supply pipe 9 and the oil inlet pipe 15 are connected by a joint, the oil inlet pipe 15 extends into the interior of the fuel injection tank 10, and one end of the oil inlet pipe 15 located inside the fuel injection tank 10 is provided with an anti-backflow component for preventing gas from entering the fuel supply pipe 9. The oil inlet pipe 15 is installed on the top of the fuel injection tank 10, which can facilitate the connection with the fuel supply pipe 9. The anti-backflow component can prevent the excessive air pressure inside the fuel injection tank 10 from entering the fuel supply pipe 9, so as to maintain a higher air pressure inside the fuel injection tank 10 and facilitate the vaporization and atomization of the fuel.

[0027] On the basis of the above embodiments, specifically, the anti-backflow assembly includes a conical plate 16 that cooperates with the oil inlet pipe 15, and a plurality of guide rods 17 are installed inside the fuel injection tank 10. The outer edge of the conical plate 16 is slidably connected to the guide rod 17, and the outer side of the guide rod 17 is provided with a spring 18 connected to the conical plate 16. The conical plate 16 can be slidably connected to one end of the oil inlet pipe 15 through the guide rod 17, and the spring 18 can facilitate the resetting of the conical plate 16. The bottom of the conical plate 16 is empty and can form an air collecting hood. The air pressure inside the fuel injection tank 10 can make the connection between the air collecting hood and the oil inlet pipe 15 more stable to prevent gas from entering. When the hydraulic pressure in the fuel supply pipe 9 is higher than the air pressure inside the fuel injection tank 10, a gap will be formed between the conical plate 16 and the oil inlet pipe 15, which can facilitate the entry of fuel into the fuel injection tank 10.

[0028] When this fuel stove is in use, the oil pump 8 can transport the fuel to the fuel injection tank 10 through the oil supply pipe 9. When the hydraulic pressure inside the oil supply pipe 9 is higher than the air pressure inside the fuel injection tank 10, a gap will be formed between the conical plate 16 and the oil inlet pipe 15, and the fuel will enter the fuel injection tank 10 through this gap. Then the fuel will enter the gap between the separation column 12 and the fuel injection tank 10 and form an oil film. The oil film will gather near the fuel injection micropores 11 at the bottom. At the same time, the air supply pump 3 will spray high-pressure gas onto the fuel injection micropores 11 through the jet holes 14 to provide power for the oil near the fuel injection micropores 11. Since the total amount of oil near the fuel injection micropores 11 is very small, a small amount of oil will form a Venturi effect near the fuel injection micropores 11. In this process, the oil will be atomized to form oil droplets that are fully mixed with air and enter the vaporization chamber 21 in a mixed state. As the oil continues to atomize, the atomized oil will be blown out from the fire holes 6 on the outer fire cover 5, and the igniter 7 can ignite the blown oil-gas mixture for easy use.

[0029] In one embodiment, specifically, a return pipe 19 is connected to the bottom of the vaporization chamber 21, and the return pipe 19 is connected to the fuel tank 2. The return pipe 19 can recover the fuel that is not fully atomized inside the vaporization chamber 21 into the fuel tank to avoid wasting fuel.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
