[0021] like Figure 1-Figure 7 As shown, an automatic fuel supply assembly for an engine is mainly composed of a fuel pump 2 and a housing 1. The fuel pump 2 is arranged in the housing. To achieve the passage of fuel, an oil inlet hole 2a connected to the fuel tank is vertically arranged in the fuel pump 2, and an oil inlet channel 1a for communicating with the upper end of the oil inlet hole 2a is horizontally arranged on the housing 1. The fuel pumps are all prior art and will not be described in detail here.
[0022] In order to realize automatic oil supply, a control component is arranged in the housing 1, and a sensor component 9 is arranged in the middle of the lower part of the housing 1, which can be inserted into the oil tank to detect the oil level in the oil tank, and the fuel pump 2 and the sensor component 9 are electrically connected to the control component. The control component adopts a control board with information processing function, information receiving function, information sending function and charging function in the prior art, and the sensor component can adopt a combination of a reed switch, a high-level sensor and a low-level sensor. At the same time, an indicator light for indicating the oil supply status, a switch button for turning on the entire device and a power port for connecting the control component to a power source are also arranged on the housing.
[0023] To facilitate observation of the oil inlet status, an observation channel 1b connected to the top surface of the shell 1 is vertically arranged at the end of the shell 1 located at the oil inlet channel 1a away from the oil inlet nozzle 4, and the observation channel 1b is connected to the end of the oil inlet channel 1a away from the oil inlet nozzle 4. At the same time, an observation component for easy observation is arranged in the observation channel 1b. Of course, observation components may also be arranged at other positions of the shell's oil inlet channel.
[0024] The observation assembly includes a transparent observation window 5 disposed at the upper end of the observation channel 1b, and an observation seal ring 6 is disposed between the observation window 5 and the housing 1. Preferably, the observation window is installed at the upper end of the observation channel 1b by threaded connection, and of course the observation window can also be installed by snap-fitting or other means.
[0025] A filter screen 7 may also be provided at a position where the observation channel 1b is connected to the end of the oil inlet channel 1a away from the oil inlet nozzle 4, so that the fuel entering the fuel tank can be filtered through the filter screen to improve the quality of the fuel entering the fuel tank.
[0026] To facilitate the installation of the entire oil supply assembly, a fuel tank cap 3 for installing the fuel supply assembly at the fuel tank opening is provided at the lower end of the housing 1, and the sensor assembly 9 is provided below the fuel tank cap 3. To facilitate the installation of the fuel tank clamping parts and the sealing of the fuel tank, a fuel tank sealing ring 12 is provided on the inner side of the bottom surface of the fuel tank cap 3 to ensure the sealing of the fuel tank.
[0027] Since the structure of the oil inlet of the oil tank has a threaded or clamped structure, a variety of oil tank caps can be provided for connecting with different oil tanks, and the connection between the oil tank cap and different oil tanks can also be achieved by adding a conversion head 8 under the oil tank cap.

A fuel tank clamping piece 3c is arranged between the inner fuel tank cover 3a and the outer fuel tank cover 3b to prevent the fuel tank from falling out of the fuel tank after installation. The fuel tank clamping piece 3c is provided with at least one clamping end. Correspondingly, a protrusion hole is provided on the inner fuel tank cover 3a for the clamping end on the fuel tank clamping piece 3c to extend out, so that the fuel tank cover can be clamped at the fuel tank port, so that the fuel tank cover can be installed at the corresponding fuel tank inlet by clamping. In order to facilitate the installation of the fuel tank sealing ring 12, a protrusion is arranged downward on the bottom surface of the middle part of the fuel tank inner cover, and the fuel tank sealing ring is sleeved outside the protrusion, and the protrusion is arranged on the side of the protrusion.
[0029] In order to match the use of the oil inlet of the oil tank as a threaded structure, an internal thread matching the external thread of the oil tank is provided on the adapter 8. The adapter 8 includes an adapter inner cover 8a and an adapter outer cover 8b arranged inside and outside, and the adapter outer cover is made of metal material, and the adapter inner cover is made of plastic material, and the adapter inner cover and the adapter outer cover can be installed by press fitting. In order to achieve the installation of the adapter and the oil tank cover, a clamping flange for the oil tank clamping part 3c to be clamped is provided inwardly at the upper end of the adapter outer cover 8b, and a gap is left between the bottom of the clamping flange and the upper end of the adapter inner cover 8a. The internal thread is provided on the adapter inner cover, and in order to adapt to oil tanks with various thread specifications, the specifications of the internal thread are various, and at the same time, an adapter sealing ring 8d is provided at the inner side of the adapter inner cover 8a at the position of the upper end of the internal thread.
[0030] Of course, the inner cover of the fuel tank may also be provided with an internal thread, and the corresponding adapter may be provided with a clamping structure, and the adapter and the inner cover of the fuel tank may be connected via threads.
[0031] In order to realize the connection between the oil supply assembly and the oil pipe, an oil inlet nozzle 4 is arranged at the end of the oil inlet channel 1a away from the oil tank. At the same time, a limit column 10 parallel to the oil inlet nozzle is arranged on the shell, and the limit column is equipped with a dust cover 11 covering the limit column and the oil inlet nozzle.
