Description

Technical Field

[0001] The utility model relates to a fuel generator, in particular to a fuel generator with an external gasoline pump. Background Art

[0002] A fuel generator is a small power generation device, which refers to a power machine that uses fuel as fuel and a fuel engine as the prime mover to drive the generator to generate electricity. It is mainly composed of a fuel engine, a generator, a control system, a base, a shock absorber, a cooling system, a fuel supply system, and an output protection switch. In order to ensure the normal supply of fuel, a fuel pump is usually used in a fuel generator to transport the fuel in the fuel tank to the power unit. The gasoline pump plays a key role in the fuel system. Once the temperature of the gasoline pump is too high, it will not work or work abnormally.

[0003] Chinese patent document CN214836802U discloses an oil pump type fuel supply generator set, including a closed shell with an air inlet window, wherein a power unit, a fuel tank and an oil pump type fuel supply system connecting the power unit and the fuel tank are arranged inside the shell, and the oil pump of the oil pump type fuel supply system is located outside the fuel tank. This solution solves the problem of complex assembly operation of small and medium-sized oil pump type fuel supply generators in the prior art. In the prior art, the volume of the fuel tank can be maximized by arranging the oil pump outside the fuel tank, thereby extending the working time of the generator. However, during the operation of the generator, a large amount of heat will be generated inside the generator, causing the temperature of the gasoline pump to rise. Once the gasoline pump is overheated, it is easy to cause the gasoline pump to be damaged, affecting the normal use of the generator. Utility Model Content

[0004] In order to solve the technical problem in the prior art that a gasoline pump is prone to high temperature and affects the normal use of a generator, the utility model provides a fuel generator, including a shell, a power unit and a cooling fan are arranged in the shell, the power unit is connected to a gasoline pump through an oil pipe, and the other end of the gasoline pump is connected to a fuel supply device; wherein: a mounting portion is arranged outside the shell, the gasoline pump is arranged in the mounting portion, and one end of the oil pipe passes through the shell and is connected to the gasoline pump.

[0005] Compared with the prior art, in this solution, after a mounting portion is provided on the outside of the shell, the gasoline pump is located inside the mounting portion, that is, the gasoline pump is provided outside the shell. Therefore, the shell separates the gasoline pump from the inside of the generator, thereby effectively isolating the thermal influence of the heat generated by the power unit during use on the gasoline pump, thereby extending the service life of the gasoline pump.

[0006] Furthermore, in the prior art, since the gasoline pump is arranged inside the generator housing, when the gasoline pump needs to be maintained, the housing needs to be disassembled for maintenance. However, in the present solution, since the gasoline pump is installed outside the housing, when the gasoline pump needs to be maintained, the gasoline pump outside the housing can be directly maintained, thereby improving the maintainability of the gasoline pump.

[0007] Preferably, the mounting portion is a mounting groove concavely arranged at the bottom of the housing. This solution can ensure the compactness of the fuel generator structure.

[0008] Preferably, a bracket is provided on the mounting portion, and the gasoline pump is fixed on the bracket. This solution facilitates the installation of the gasoline pump on the housing.

[0009] Preferably, the bracket is provided with an arc surface that fits the gasoline pump. This solution can protect the gasoline pump and prevent the gasoline pump from being damaged due to external collision.

[0010] Preferably, a heat sink for the gasoline pump is provided on the mounting portion. This solution utilizes the heat sink to dissipate heat from the gasoline pump, thereby lowering the temperature of the gasoline pump and thus avoiding the problem of damage to the gasoline pump caused by overheating.

[0011] Preferably, the heat sink is a ventilation hole opened on the housing toward the gasoline pump. In this solution, the ventilation hole is used as the heat sink. When the generator is in use, the housing forms a negative pressure through the cooling fan, so that the external air will flow into the generator from the ventilation hole for cooling. When the air passes through the ventilation hole, the gasoline pump will also be cooled, thereby avoiding the problem of overheating and damage of the gasoline pump. The structure is simple.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model separates the gasoline pump from the inside of the generator, thereby effectively isolating the thermal influence of the heat generated by the power unit during use on the gasoline pump, thereby extending the service life of the gasoline pump;

[0014] 2. When the gasoline pump needs to be maintained, the utility model can directly maintain the gasoline pump outside the housing, thereby improving the maintainability of the gasoline pump.

[0015] 3. The utility model can cool down the gasoline pump, thereby avoiding the problem of overheating and damage of the gasoline pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is further described in detail through specific implementation methods:

[0021] 1. Definition

[0022] Power unit: refers to an engine, a machine that can convert other forms of energy into mechanical energy. In the utility model, the power unit is an internal combustion engine, which is a machine that converts chemical energy into mechanical energy.

[0023] Gasoline pump: It sucks gasoline from the fuel tank and sends it to the float chamber of the carburetor through the pipeline and gasoline filter. Gasoline pumps can be divided into two types according to the driving method: mechanical drive diaphragm type and electric drive type.

[0024] Fuel supply equipment: a device for storing fuel, which in this utility model refers to the fuel tank.

[0025] 2. The reference numerals in the drawings of the specification include: housing 1, mounting portion 2, gasoline pump 3, bracket 4, heat sink 5, oil pipe 6.

[0026] The embodiment is basically as shown in the attached Figure 1-Figure 4 As shown: a fuel generator includes a housing 1, a power unit and a cooling fan are arranged in the housing 1, the power unit is connected to a gasoline pump 3 through an oil pipe 6, and the other end of the gasoline pump 3 is connected to a fuel supply device. The power unit is an engine, and the fuel supply device is a fuel tank. In this embodiment, the fuel tank can be a fuel tank provided by the fuel generator. If the fuel generator does not have a fuel tank, the fuel supply device is an external fuel tank.

[0027] The housing 1 is provided with a mounting portion 2 outside, the gasoline pump 3 is arranged inside the mounting portion 2, and one end of the oil pipe 6 passes through the housing 1 and is connected to the gasoline pump 3. Specifically, a concave mounting groove is provided at a top corner of the bottom of the housing 1, and a bracket 4 is detachably connected to the mounting groove on the housing 1. One end of the bracket 4 is fixed to the bottom surface of the housing 1 by bolts, and the gasoline pump 3 is fixed to the bracket 4. The other end of the bracket 4 is provided with an arc surface that fits the gasoline pump 3, such as Figure 3 The gasoline pump 3 is placed in the arc surface, and the arc surface supports the gasoline pump 3. The setting of the arc surface can separate the gasoline pump 3 from the outside world, thereby preventing the gasoline pump 3 from being hit by the outside world.

[0028] A heat sink 5 for the gasoline pump 3 is also provided at the bottom of the housing 1. In this embodiment, the heat sink 5 is a ventilation hole provided on the bottom side wall of the housing 1. The ventilation hole is provided toward the gasoline pump 3. There are six ventilation holes on the housing 1, which are arranged in two rows and three lines. Figure 4 The length of the heat sink 5 matches the length of the gasoline pump 3, thereby ensuring that the airflow can pass through the entire gasoline pump 3.

[0029] The specific implementation process is as follows: When in use, the gasoline pump 3 is connected to the fuel supply device through the oil pipe 6. When the fuel generator is working, the gasoline pump 3 extracts fuel from the fuel supply device and sends it to the power unit for use by the power unit. At the same time, the cooling fan is started, and negative pressure is formed in the housing 1, so the external cold air will flow to the heat sink 5 and then enter the inside of the housing 1 to cool the inside of the housing 1. When the cold air flows to the heat sink 5, it will pass through the gasoline pump 3, thereby also cooling the gasoline pump 3.
