[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," "outer," and the like, indicating directions or positions, are based on the directions or positions shown in the accompanying drawings and are intended solely for the purpose of facilitating and simplifying the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific manner. Therefore, they should not be construed as limiting the present invention. The terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1 and Figure 2 As shown ( Figure 1 A portable multi-fuel variable frequency generator (not shown) includes a gas pipe 6, the end of which is connected to a carburetor. Connecting the gas pipe 6 to the carburetor (not shown) allows gas to enter the combustion chamber directly, thereby starting the generator. The carburetor configuration of this application is the same as that of conventional fuel (gasoline or diesel) generators and is therefore not shown.

[0022] In this embodiment, the starting end of the gas pipe 6 is connected to a split pressure-reducing valve 5, which is fixed to the generator housing 12. The inlet of the split pressure-reducing valve 5 is connected to the air intake pipe 51, while its two outlets are connected to the gas pipe 6 and the balancing gas pipe 8, respectively. The balancing gas pipe 8 is connected to the oil-gas switching valve 9. In other words, gas enters the split pressure-reducing valve 5 through the air intake pipe 51. The split pressure-reducing valve 5 has two outlets: one connected to the oil-gas switching valve 9 via the balancing gas pipe 8, and the other connected to the carburetor via the gas pipe 6.

[0023] like Figures 3 to 5 As shown, the oil-gas switching valve 9 includes a housing 91, within which is disposed a valve disc 92. In the present invention, valve disc 92 is made of a material with a certain degree of elasticity, such as rubber, TPE, PVC, or a silicone membrane. A protrusion 921 is provided on the circumference of valve disc 92, and the outer periphery is sealed to the housing 91. Valve disc 92 divides the interior of housing 91 into an intake chamber 93 and a movable chamber 94. The intake chamber 93 communicates with the balancing air pipe 8, while the movable chamber 94 communicates with the movable passage 11. A needle valve 95 is disposed within movable passage 11, which can block the fuel passage 10.

[0024] Specifically, valve disc 92 is connected to a first magnetic block 96 on the side facing movable chamber 94. The free end of first magnetic block 96 extends into movable channel 11. A second magnetic block 97 is also disposed within movable channel 11. The adjacent ends of first magnetic block 96 and second magnetic block 97 have the same magnetic poles, creating a repulsive force between them. Second magnetic block 97 abuts the rear end of needle valve 95, with the front end of needle valve 95 aligned with fuel channel 10. A spring 98 is mounted on the outer sleeve of needle valve 95. One end of spring 98 abuts against the outer protrusion at the rear end of needle valve 95, while the other end is confined within the sidewall of movable channel 11.

[0025] When sufficient gas is present in the balancing gas pipe 8, it vents into the inlet chamber 93. As pressure within the inlet chamber 93 increases, the valve disc 92 shifts toward the active chamber 94. In this embodiment, the valve disc 92 is circular, with a first magnet 96 attached to its center. A protrusion 921 projects toward the movable passage 11. The presence of the protrusion 921 further enhances the overall elasticity of the valve disc 92. This allows the valve disc 92 to maintain good maneuverability and resist damage even under prolonged and repeated exposure to gas pressure. When the gas pressure on the valve disc 92 is sufficiently high, its center moves toward the movable passage 11, thereby driving the first magnet 96. The first and second magnets 96, 97, have the same magnetic poles at their adjacent ends, repelling each other, which in turn drives the second magnet 97 in the same direction. This movement of the second magnet 97 pushes the needle valve 95, which in turn moves toward the fuel passage 10, blocking it and preventing fuel flow. In the present application, the fuel channel 10 is a connecting channel between the fuel inlet nozzle and the carburetor. At this time, the gas enters the carburetor smoothly and then enters the combustion chamber for combustion. When the gas is insufficient, the gas entering the balance gas pipe 8 is also insufficient. When the valve plate 92 is not subjected to force, it will return to its natural state, the first magnetic block 96 will naturally rebound, and the second magnetic block 97 will release the repulsive force. At the same time, the spring 98 will return (the second magnetic block 97 will squeeze the spring when pushing the needle valve 95). Under the action of the elastic force, the needle valve 95 moves toward the second magnetic block 97, unblocking the fuel channel 10. The fuel channel 10 is unblocked, so that the generator can use fuel for combustion normally.

[0026] The starting end of the air inlet pipe 51 is connected to the pressure reducing valve 3, and the other end of the pressure reducing valve 3 is connected to the fuel tank 2. The fuel tank 2 is provided with at least one air inlet, and the air outlet of the fuel tank 2 is connected to the pressure reducing valve 3, and the air inlet is connected to the gas source 1. In this embodiment, the fuel tank 2 is provided with three air inlets and one air outlet, each of which is connected to a gas source, and the air outlet is connected to the pressure reducing valve 3. The reduced-pressure gas is connected to the split pressure reducing valve 5 through the air inlet pipe 51.

[0027] When the utility model is used, the gas is reduced in two stages by the pressure reducing valve 3 and the split pressure reducing valve 5, then enters the carburetor, and then enters the engine combustion chamber for combustion and power generation. The gas pressure can be reduced to meet the combustion requirements of the generator, so that the generator can use common cassette gas bottles in addition to fuel oil, realizing multi-fuel function. The fuel tank has three air inlets, which can realize the simultaneous use of three gas bottles (gas source 1 uses a gas bottle), making the generator work longer and reducing the frequency of changing gas bottles.

[0028] More specifically, when the present invention is used, the pressure reducing valve 3 and the split pressure reducing valve 5 are opened, and gas from the gas source 1 enters the fuel tank 2 and the air intake pipe 51, then passes through the split pressure reducing valve 5 and enters the gas pipe 6 and the balance air pipe 8, respectively. After the balance air pipe 8 is ventilated, as described above, the needle valve 95 blocks the fuel passage 10, preventing fuel from entering the carburetor. At this point, the generator is started, and the combustion chamber intake creates a negative pressure due to natural aspiration. This negative pressure forces the gas in the gas pipe connected to the combustion chamber intake into the combustion chamber, igniting the generator and starting it. When the pressure reducing valve 3 is closed or the gas is consumed, the pressure in the oil-gas switching valve 9 decreases, causing the valve plate 92 to rebound, thereby opening the fuel passage and enabling fuel-fired power generation.

[0029] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
