Portable oil extraction pump

A portable oil extraction pump, comprising:

• a mainframe comprising a control cavity and a first routing hole connected to the control cavity, the portable oil extraction pump further comprising a circuit board and a battery electrically connected to the circuit board, the circuit board and the battery being configured in the control cavity;
• an oil extraction tube connected to the mainframe;
• a pump body configured in the oil extraction tube;
• and
• an oil outlet tube;
• wherein the pump body is connected to the circuit board through a wire, a first sealing member is configured between the oil extraction tube and the mainframe to prevent an oil from entering the control cavity, the material of the first sealing member is a rubber, the wire passes through the first sealing member and the first routing hole and is electrically connected to the circuit board, the wire is connected with the first sealing member and/or the first routing hole through an interference fit;
• the oil outlet tube is connected with the oil extraction tube, when the pump body is driven, the oil is pumped through the oil extraction tube and output through the oil outlet tube;
• wherein the mainframe further comprises an adapter cavity, one end of the oil extraction tube is placed in the adapter cavity, the mainframe is configured with a first separator plate between the adapter cavity and the control cavity, the first sealing member is at least partially located between the first separator plate and the oil extraction tube;
• the first routing hole is provided on the first separator plate, or the first routing hole is disposed on one side of the first separator plate opposite to the oil extraction tube, the wire passes through the first separator plate;
• a junction structure is located between the mainframe and the oil extraction tube, the junction structure is disposed at one end of the adapter cavity opposite to the control cavity;
• the junction structure comprises at least one embedment convex block and a second embedment groove matching with the embedment convex block, and the embedment convex block is disposed in the second embedment groove.
