In the initial state, the external oil tank is filled with gasoline, the micro liquid pump 22 is filled with a proper amount of cooling liquid, and the circuit of the micro motor 54 is controlled to be disconnected; at this time, in the sliding cavity 52, the working circuit path of the electromagnet plate 522 operates, the electromagnet plate 522 has magnetism, the left end of the sliding rack 53 is fixedly connected with the electromagnet plate 522, the sliding rack 53 is positioned at the left side of the sliding cavity 52, the elastic rod 531 is in a stretching state, and the liquid supply channel 60 is in an axial direction at this time;
when the oil pump core 14 starts to operate, the oil inlet pipe 16 guides oil in the oil tank into the oil pump shell 10, the oil is pumped out through the oil pump core 14 and is guided out through the oil supply pipe 17 sequentially through the flow direction adjusting ball 50, the oil outlet pipe 15 and the overflow valve 30, when the gasoline passes through the liquid supply channel 60 in the flow direction adjusting ball 50, due to the limitation of the bending degree of the elastic sealing plate 61 arranged in the backflow channel 62, the elastic sealing plate 61 cannot be turned and bent in the direction far away from the liquid supply channel 60, at the moment, the oil only flows in the direction of the liquid supply channel 60, and when the oil pressure in the oil supply pipe 17 is too high, the oil guided into the overflow valve 30 by the oil outlet pipe 15 flows back to an external oil tank from the overflow channel 31.
Because the driving part of the oil pump core 14 is an electromagnetic rotor, the electromagnetic rotor can generate heat when in work, and because the gasification temperature of the gasoline is lower, when the oil pump core 14 pumps the gasoline, the temperature of the gasoline can be gradually increased due to the heat generated by the electromagnetic rotor, so that the gasoline can be gradually gasified to form bubbles, and thus when the gasoline is introduced into the motorcycle engine, the work done by the motorcycle engine is abnormal because the gasoline is gasified;
in this embodiment, when the heat released by the electromagnetic rotor is high, the gasoline is gasified, when the gasoline flows through the intermediate connecting pipe 41, because the inside of the intermediate connecting pipe 41 is in a sealed state, the gasoline changes from a liquid state to a gas state, the pressure in the intermediate connecting pipe 41 increases, so that the annular elastic sheet 51 expands in a direction close to the intermediate connecting pipe 41, so that the gas in the gap between the intermediate connecting pipe 41 and the annular elastic sheet 51 enters the side of the sliding cavity 52 close to the oil pump core 14, at this time, the temperature of the gas in the sliding cavity 52 increases, after the temperature sensor in the sensing cavity 521 detects the temperature increase, the operating circuit of the electromagnetic plate 522 is controlled to be open, the electromagnetic plate 522 loses magnetism, the electromagnetic plate 522 is separated from the sliding rack 53, at this time, the elastic restoring force of the elastic rod 531 controls the sliding rack 53 to move in a direction away from the electromagnetic plate 522, thereby driving the gear shaft 55 to rotate, thereby driving the flow direction regulating ball 50 to rotate, so that the flow direction regulating ball 60 changes from an axial direction to a radial direction, the opening of the return flow channel 62 is opened toward the oil pump core 14, when the flow direction regulating ball 50 rotates 90 degrees, the flow regulating ball 50, therefore, the flow regulating ball cannot continue to the flow regulating ball 50 in a short time, and the flow regulating ball 50, and the flow regulating ball can continue to the flow regulating ball 50, and the flow regulating ball 50, thus the flow regulating ball 50, and the oil pump 50 can continue to the oil pump 14, and the oil pump 50, and the oil pump 14, thereby, and the oil pump is regulated ball is regulated by the oil pump 50 can continue to the oil pump 50, and the flow regulating ball is stopped in a short time, at the moment, the gasoline entering the backflow channel 62 from the backflow channel 62 flows in the same direction as the bending direction of the elastic sealing plate 61, at the moment, the elastic sealing plate 61 bends towards the direction of the liquid supply channel 60, so that the backflow channel 62 is opened, at the same time, because one end of the two ends of the liquid supply channel 60 is in a closed state at the moment, the other end of the two ends of the liquid supply channel 60 is communicated with the backflow accelerating channel 56, at the moment, the oil flows to the backflow accelerating channel 56, the flowing speed of the gasoline is increased again under the action of gravity, and the oil enters the backflow pipe 42 through the backflow connector 43 and finally flows back to the inside of the oil inlet pipe 16;
during the gasoline backflow process, the pressure sensor enables the micro liquid pump 22 to be started through a circuit which is communicated with and controls the micro liquid pump 22 to be electrified, so that cooling liquid in the micro liquid pump 22 flows in the heat dissipation pipeline 21 and finally returns to the micro liquid pump 22 again, the temperature of the gasoline flowing through the backflow pipeline 42 with higher temperature is rapidly reduced and is changed into liquid again, meanwhile, the temperature of the gasoline in the oil pump shell 10 and the temperature of the gasoline in the oil pump core 14 are reduced, the gasoline cannot be gasified, at the moment, the air pressure in the intermediate connecting pipeline 41 is reduced, the annular elastic sheet 51 is not expanded, the air pressure between the intermediate connecting pipeline 41 and the annular elastic sheet 51 is reduced, at the moment, the gas in the sliding cavity 52 moves to a gap between the annular elastic sheet 51 and the intermediate connecting pipeline 41, the sliding rack 53 is further moved reversely, the flow direction adjusting ball 50 is reset through the reverse movement path of the process, after the resetting, the liquid supply channel 60 is axially along the intermediate connecting pipeline 41, the backflow channel 62 is aligned with the backflow acceleration channel 56, at the moment, the oil can still continuously enter the oil outlet pipe 15 for supplying, when the oil temperature stops working, the micro liquid pump 22 can not operate, and the micro oil pump can not work, and the micro oil pump 22 can only does not work, and can not work.
Example 2:

after the micro motor 54 is installed, when the annular elastic sheet 51 expands, the air pressure between the middle connecting pipeline 41 and the annular elastic sheet 51 is increased, the circuit of the micro motor 54 is communicated through the second pressure sensor, the micro motor 54 can be directly started to drive the flow direction adjusting ball 50 to rotate for ninety degrees through the gear shaft 55, then the micro motor 54 stops, and the flow direction adjusting ball 50 completes oil path switching operation in a short time, so that the amount of high-temperature gasoline supplied to an engine is reduced, and meanwhile, the flow direction adjusting ball 50 can be reset and rotated in a short time after the annular elastic sheet 51 stops expanding, and the loss amount of returned gasoline is reduced;
when the micro motor 54 is damaged and cannot work, the gear shaft 55 is driven to rotate and the rotation of the flow direction adjusting ball 50 is completed by the horizontal movement of the sliding rack 53 according to the first embodiment.
