After oil drainage is finished, the motor 40 drives the rotating cup 20 to rotate for a set angle, so that the oil storage cavity 21 is communicated with the first oil cavity 13 through the oil conveying cavity 22, the motor 40 and the control coil 33 are powered off, and the oil storage cavity 21 is kept communicated with the first oil cavity 13; after the control coil 33 is powered off, the memory alloy 32 is reset due to the disappearance of the external magnetic field, the plunger body 31 moves in the direction away from the bottom of the oil storage chamber 21, the volume of the oil storage chamber 21 is increased, and the external liquid enters the oil storage chamber 21 through the first oil chamber 13 and the oil delivery chamber 22. The oil suction and oil discharge actions are completed.
In other embodiments, when the memory alloy 32 is designed to be in other deformation forms, the plunger body 31 and the memory alloy 32 may be connected at an angle, and the moving direction of the plunger body 31 is in the direction of the maximum driving force for deforming the memory alloy 32.
In a preferred embodiment of the present invention, the memory alloy 32 pushes the plunger body 31 to move back and forth in the oil chamber 21, and the plunger body 31 cannot move stably because the vibration of the memory alloy 32 from the axial direction is not controllable when the memory alloy is axially expanded and contracted. Therefore, the plunger body 31 is provided with a stopper 311 and a stopper rod 312, one end of the stopper rod 312 is hermetically inserted into the oil storage chamber 21, the other end of the stopper rod 312 is fixedly connected with the stopper 311, the stopper 311 is matched with the cavity 11, and the cavity 11 guides the stopper 311. Due to the limit of the stopper 311, the stopper rod 312 can only move along the axial direction of the cavity 11, and even if the stretching and retracting of the memory alloy 32 have vibration deviating from the axial direction, the movement of the stopper rod 312 in the oil storage chamber 21 is not influenced.
In the present embodiment, when energized, the motor 40 drives the rotating cup 20 to rotate by a set angle, so that the oil storage chamber 21 communicates with the second oil chamber 14 through the oil delivery chamber 22; the control coil 33 generates a magnetic field around the control coil after being electrified, the memory alloy 32 extends under the action of the magnetic field, the memory alloy 32 pushes the stopper 311 out towards the bottom of the oil storage cavity 21, namely towards the left side in fig. 1, the cross section of the stopper 311 is matched with that of the cavity 11, so that the stopper 311 can only move along the axial direction of the cavity 11, the plug can only move along the axial direction of the oil storage cavity 21, and the sealing between the plug and the oil storage cavity 21 in the moving process is ensured. As the plug is inserted into the oil reservoir chamber 21, the liquid in the oil reservoir chamber 21 is discharged through the oil delivery chamber 22 and the second oil chamber 14. After oil drainage is finished, the motor 40 drives the rotating cup 20 to rotate for a set angle, so that the oil storage cavity 21 is communicated with the first oil cavity 13 through the oil conveying cavity 22, the motor 40 and the control coil 33 are powered off, and the oil storage cavity 21 is kept communicated with the first oil cavity 13; after the control coil 33 is powered off, the memory alloy 32 is reset due to the disappearance of the external magnetic field, the stopper 311 is driven to move towards the direction far away from the bottom of the oil storage cavity 21, and the end part of the plug moves to the opening end of the oil storage cavity 21. The volume of the oil reservoir chamber 21 increases and external fluid is sucked into the oil reservoir chamber 21. Because cavity 11 is spacing to stopper 311, the plunger can only remove along a direction for even the plunger is few with the coincidence part in oil storage chamber 21, the plunger can not produce and rock, guarantees with the sealed of oil storage chamber 21.
In other embodiments, a guide groove may be provided in the cavity 11, and the stopper 311 cooperates with the guide groove to form a guide, or other guide ways.
As a preferred embodiment of the present invention, since the memory alloy 32 can be deformed rapidly under the action of the magnetic field, after the magnetic field disappears, the recovery speed of the memory alloy 32 is relatively slow, which affects the corresponding speed of the control pump.
