Description

Technical Field

[0001] The utility model relates to a generator, in particular to a miniaturized generator. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a fuel engine and converts the energy generated by fuel combustion into mechanical energy, which is then transmitted to the generator, and then converted into electrical energy. Currently, most automotive generators are driven by gasoline or diesel engines. The layout structure is not very reasonable, the size is large, and the weight is heavy, which leads to a large vehicle weight and increased fuel consumption.

[0003] Chinese patent document CN207131488U discloses a small generator, including a frame, a power assembly, a rotation limit device, a pull rod, an L-shaped oil tank, a tool box and a panel assembly. The power assembly is fixed to the bottom surface of the frame. The L-shaped oil tank is fixed to the frame and is located at the upper end of the power assembly. The tool box is fixed to the frame and is located at the upper end of the L-shaped oil tank. The panel assembly is fixed to the pull rod, and the pull rod is fixed to the frame through a rotation limit device. When the pull rod is lowered, the panel assembly is located at the upper end of the tool box. The panel of the utility model is hidden inside, which can better protect the panel; the L-shaped oil tank with a convenient tool box can save more space; the side is provided with a decorative panel, which effectively blocks the internal electrical components and circuits, making the overall appearance more beautiful. Although the prior art is provided with a convenient tool box and an L-shaped oil tank, it still has the problem of large volume and weight. Once the volume of the oil tank is reduced, the oil storage capacity will be reduced, and the oil supply to the generator will be reduced, affecting the normal use of the generator. Utility Model Content

[0004] In order to solve the technical problem of large size and weight of generators in the prior art, the utility model provides a generator, which is arranged on a working device and comprises a shell, an engine, a gasoline pump and an oil pipe. The engine and the oil pipe are located in the shell, and the gasoline pump is connected to the engine through the oil pipe; wherein: the gasoline pump is located outside the shell and connected to the oil tank of the working device, and one end of the oil pipe passes through the shell and is connected to the gasoline pump.

[0005] Compared with the prior art, the present invention adopts an external gasoline pump to introduce fuel from external working equipment, which directly eliminates the need to set up a fuel tank on the generator. That is, the generator itself does not have a fuel tank, so the weight of the fuel tank and the installation volume of the fuel tank can be directly eliminated, which can realize the miniaturization and lightweight of the generator, reduce vehicle fuel consumption, be suitable for different vehicle models, simplify the generator structure, and reduce the cost of the generator.

[0006] Preferably, the oil pipe is fixed on the housing. This solution can ensure the normal delivery of fuel.

[0007] Preferably, the end of the oil pipe connected to the engine is arranged higher than the end of the oil pipe connected to the gasoline pump. This solution can ensure that the excess fuel in the oil pipe returns to the fuel tank when the generator stops running, avoiding fuel waste.

[0008] Preferably, one end of the oil pipe connected to the gasoline pump is fixed to the housing base. This solution can ensure that when the generator stops running, the excess fuel in the oil pipe returns to the fuel tank smoothly, avoiding fuel waste.

[0009] Preferably, the fuel pump is located at the base of the housing. This solution can ensure that when the generator stops running, the excess fuel in the oil pipe returns to the fuel tank, avoiding fuel waste.

[0010] Preferably, the gasoline pump is located at the top corner of the side of the housing base. This solution facilitates the installation of the gasoline pump on the housing and can also ensure the beauty of the generator.

[0011] The utility model has the following beneficial effects:

[0012] 1. By adopting an external gasoline pump, fuel can be introduced from external working equipment, which directly saves the need to set up a fuel tank on the generator. That is, the generator itself does not have a fuel tank, which can directly save the weight of the fuel tank and the installation volume of the fuel tank. It can realize the miniaturization and lightweight of the generator, reduce vehicle fuel consumption, be suitable for different models, simplify the generator structure, and reduce the cost of the generator.

[0013] 2. It can ensure that the excess fuel in the oil pipe returns to the fuel tank smoothly when the generator stops running, avoiding fuel waste.

[0014] 3. It is convenient to install the gasoline pump on the casing and ensure the beauty of the generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is further described in detail through specific implementation methods:

[0018] 1. Definition

[0019] Engine: A machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy.

[0020] Gasoline pump: sucks gasoline from the fuel tank and sends it to the float chamber of the carburetor through the pipeline and the gasoline filter. Gasoline pumps can be divided into two types according to the driving mode: mechanical drive diaphragm type and electric drive type. The utility model adopts an electric drive gasoline pump.

[0021] Vertex angle: refers to the angle formed by two sides.

[0022] 2. The reference numerals in the drawings of the specification include: housing 1, gasoline pump 2, second connection end 3, first connection end 4, housing base 5.

[0023] The embodiment is basically as shown in the attached Figure 1 and Figure 2 As shown: A generator, arranged on a working device, comprises a housing 1, an engine, a gasoline pump 2 and an oil pipe, wherein the engine and the oil pipe are located in the housing 1, and the gasoline pump 2 is connected to the engine through the oil pipe. The oil pipe is fixed on the housing 1, specifically, one end of the oil pipe connected to the engine is higher than one end of the oil pipe connected to the gasoline pump 2, and one end of the oil pipe connected to the gasoline pump 2 is fixed to the housing base 5, wherein one end of the oil pipe connected to the engine is a first connection end 4, and one end of the oil pipe connected to the gasoline pump 2 is a second connection end 3.

[0024] The gasoline pump 2 is located outside the housing 1 and connected to the oil tank of the working equipment, and one end of the oil pipe passes through the housing 1 and is connected to the gasoline pump 2. Specifically, the gasoline pump 2 is arranged outside the housing base 5, and preferably, the gasoline pump 2 is located at the top corner of the side of the housing base 5.

[0025] The specific implementation process is as follows: The generator in the utility model needs to be used in conjunction with a working device, such as being installed on a car. Before use, it is connected to the fuel tank of the working device through a gasoline pump 2. When in use, under the action of the gasoline pump 2, fuel is pumped from the fuel tank of the working device into the oil pipe of the generator and is used by the generator. When the generator stops running, the fuel in the oil pipe flows from the high part of the oil pipe to the low part of the oil pipe under the action of gravity, and then flows back to the fuel tank of the working device, avoiding the waste of fuel.

[0026] In this embodiment, an external gasoline pump 2 is used to introduce fuel from external working equipment for use in the generator, which directly eliminates the need to provide a fuel tank on the generator. That is, the generator itself does not have a fuel tank, so the weight of the fuel tank and the installation volume of the fuel tank can be directly eliminated, which can achieve miniaturization and lightweight of the generator, reduce vehicle fuel consumption, be suitable for different vehicle models, simplify the generator structure, and reduce the cost of the generator.
