Abstract: A portable oil extraction pump includes a mainframe, an oil extraction tube, an oil outlet tube and a pump body configured in the oil extraction tube. A mainframe includes a control cavity and a first routing hole connected to the control cavity. The control cavity is configured with a circuit board and a battery electrically connected to the circuit board. The battery is configured to supply the power to the circuit board. The oil extraction tube is connected to the mainframe. A pump body is electrically 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 first sealing member is a soft rubber. The wire passes through the first sealing member and the first routing hole.

Abstract: A portable oil pump with a charging function includes a main unit, an oil pumping pipe, a pump body, and an oil outlet pipe. The oil pumping pipe is connected to the main unit. The oil outlet pipe is in communication with the oil pumping pipe. The pump body is arranged inside the oil pumping pipe. The main unit is equipped with a circuit board, a battery, and a power interface. The battery is a rechargeable battery. A charging unit, a main control unit and a driving unit are integrated on the circuit board. The power interface is used for connecting to a first power signal and transmitting the connected first power signal to the charging unit. The charging unit is used for converting the first power signal into a second power signal for charging the battery.
