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.
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 the scheme, when the electromagnetic rotor releases high heat during working, gasoline is gasified, and when the gasoline flows through the intermediate connecting pipeline 41, because the inside of the intermediate connecting pipeline 41 is in a sealed state, the gasoline is changed from a liquid state to a gas state, the pressure in the intermediate connecting pipeline 41 is increased, so that the annular elastic sheet 51 expands towards the direction close to the intermediate connecting pipeline 41, and therefore, the gas in the gap between the intermediate connecting pipeline 41 and the annular elastic sheet 51 enters one side of the sliding cavity 52 close to the oil pump core 14, so that the sliding rack 53 is pushed to move towards the direction far away from the oil pump core 14 (at the moment, after the pressure sensor receives the pressure, the circuit for controlling the working of the micro liquid pump 22 is communicated), so that the gear shaft 55 is driven to rotate, the flow direction adjusting ball 50 is driven to rotate, the liquid supply channel 60 is changed from the axial direction to the radial direction, the opening of the backflow channel 62 faces the oil pump core 14, when the flow direction adjusting ball 50 rotates for 90 degrees, the sliding rack 53 moves to the limit position, at this time, the flow direction adjusting ball 50 cannot rotate continuously, (in the rotation process of the flow direction adjusting ball 50, because the expansion degree of the ring-mounted elastic sheet 51 is increased along with the increase of the gasification amount of the gasoline, the flow direction adjusting ball 50 cannot rotate to the position in one step in a short time, therefore, before the flow direction adjusting ball 50 rotates to the limit position, part of the gasoline can flow into the oil outlet pipe 15 through the liquid supply channel 60), after the flow direction adjusting ball 50 rotates to the limit position, the gasoline is pumped out from the oil pump core 14 and enters the backflow channel 62, because the flow direction of the gasoline entering the backflow channel 62 at this time is the same as the bending direction of the elastic sealing plate 61, at this time, the elastic sealing plate 61 bends towards the liquid supply channel 60, so that the backflow channel 62 is opened, and because one end of the two ends of the liquid supply channel 60 is in a closed state at this time, the other end is communicated with the backflow accelerating channel 56, at this time, 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 after passing through the backflow connector 43 and finally flows back to the inside of the oil inlet pipe 16;
in the gasoline reflux 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 enable cooling liquid in the micro liquid pump 22 to flow in the heat dissipation pipeline 21 and finally return to the micro liquid pump 22 again, so that the gasoline which flows through the reflux pipe 42 and has higher temperature is rapidly cooled and is changed into liquid again, meanwhile, the temperature of the gasoline in the oil pump shell 10 and the oil pump core 14 is 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 any more, the air pressure between the intermediate connecting pipeline 41 and the annular elastic sheet 51 is reduced, at the moment, the air in the sliding cavity 52 moves to the 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 opposite movement path in the process, the liquid supply channel 60 is axially arranged along the intermediate connecting pipeline 41 after the resetting is finished, the return passage 62 is aligned with the return accelerating passage 56, and at this time, the oil can still continuously enter the oil outlet pipe 15 for supply, and when the oil pump stops working, the micro liquid pump 22 continuously operates to ensure that the oil temperature cannot gasify the oil, and because when the oil pump temperature is in a normal range, the micro liquid pump 22 does not work, and only works when the oil pump temperature is too high, the service life of the micro liquid pump 22 is prolonged.
Meanwhile, 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 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 the 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 broken and does not work, the gear shaft 55 is driven to rotate by the above-mentioned horizontal movement of the sliding rack 53 and the rotation of the flow direction adjusting ball 50 is completed.
