And the vacuumizing device 7 is communicated with the bypass pipe 31 and is used for sucking air in the oil discharge pipeline 3. The vacuumizing device 7 is used for pumping air in the oil drain pipeline 3, so that negative pressure is formed inside the oil drain pipeline 3, a certain pressure difference exists between the oil pump and the oil drain pipeline 3, and fuel in the oil pump is pressed into the oil drain pipeline 3 by atmospheric pressure. In a specific embodiment, the vacuum device 7 is a suction cylinder.

The oil pump oil discharging device comprises the oil discharging pipeline 3 and the vacuumizing device 7, wherein the first control valve 4 and the second control valve 8 are arranged on the oil discharging pipeline 3, and the on-off of the oil discharging pipeline 3 can be controlled by controlling the two control valves. A bypass pipe 31 is arranged on the oil discharge pipeline 3 between the first control valve 4 and the second control valve 8, and one end of the oil discharge pipeline 3 is provided with a first quick connector 2 for connecting with the automobile oil pump 1; the vacuum pumping device 7 is communicated with the connecting pipe 211 for pumping air in the oil discharging pipeline 3.

More specifically, when the oil discharging device discharges oil, the two control valves are closed, the air in the oil discharging pipeline 3 is pumped by the vacuumizing device 7, so that negative pressure is formed in the oil discharging pipeline 3, the pressure in the oil pump is higher than the pressure in the oil discharging pipeline 3, and then the first control valve 4 is opened. The first control valve 4 is arranged near the connection part of the oil drain pipeline 3 and the outlet of the automobile oil pump 1, and the second control valve 8 is arranged at one end of the oil drain pipeline 3 far away from the automobile oil pump 1. After the first control valve 4 is opened, the fuel in the oil pump is sucked out, and after that, the second control valve 8 is opened, and continuous oil discharge can be realized by utilizing the siphon principle. The first quick connector 2 is connected with the automobile oil pump 1, so that the oil discharging device is more convenient to install and is beneficial to improving the oil discharging efficiency. In summary, the oil discharging device has a simple and novel structure and is convenient to use, and the oil discharging efficiency of the automobile oil pump 1 can be improved.

Further, the bypass pipe 31 is provided with a second quick connector 6, and the vacuumizing device 7 is communicated with the bypass pipe 31 through the second quick connector 6. The vacuumizing device 7 is connected with the oil drain pipeline 3 through the second quick connector 6, so that the whole device is arranged into a split structure, and the vacuumizing device 7 and the oil drain pipeline 3 are detachable, so that the device is convenient to transport and use, and oil drain in different occasions is suitable.

Further, the second quick connector 6 is identical in structure to the first quick connector 2;

the first quick connector 2 comprises a connector main body 21 and an elastic connecting sleeve 22, wherein a flow hole is formed in the connector main body 21 along the axial direction of the main body; the joint main body 21 comprises a connecting pipe 211 and a connecting disc 212, wherein the connecting disc 212 is arranged at one end of the connecting pipe 211, and a threaded connection part 2111 is arranged at one end, far away from the connecting disc 212, of the connecting pipe 211;

the elastic connecting sleeve 22 is detachably arranged on the connecting disc 212, the axis of the elastic connecting sleeve 22 coincides with the axis of the joint main body 21, and a sleeving part 221 is arranged at one end of the elastic connecting sleeve 22 away from the connecting tube 211.

In a preferred embodiment of the present utility model, the second quick connector 6 and the first quick connector 2 are identical in structure, and can be used interchangeably. This ensures the degree of mating of the parts, helping to reduce the cost of subsequent use. The first quick connector 2 is used as follows: the joint body 21 communicates with the oil drain pipe 3 or the bypass pipe 31 via the screw connection portion 2111, and the joint body 21 is attached. After the joint main body 21 is fixed, the elastic connecting sleeve 22 is sleeved on the automobile oil pump 1 or the vacuumizing device 7, so that the communication between the oil discharge pipeline 3 and the automobile oil pump 1 or the communication between the oil discharge pipeline 3 and the vacuumizing device 7 can be realized. In practical applications, a flange may be provided on one end of the oil drain pipe 3 or the bypass pipe 31 to facilitate the installation of the connector body 21. The elasticity required for the elastic connecting sleeve 22 should ensure that the air tightness between the parts is good after the elastic connecting sleeve is sleeved on the automobile oil pump 1 or the vacuumizing device 7.

Further, the connecting disc 212 is provided with a mounting ring 2121, and one end of the elastic connecting sleeve 22 penetrates through the mounting ring 2121 and is sleeved on the connecting disc 212. Since the elastic connecting sleeve 22 is directly sleeved on the connecting disc 212, the use is more convenient, and the replacement is easy, which can reduce the use cost. Specifically, the installation process of the elastic connecting sleeve 22 is as follows: one end of the elastic connecting sleeve 22 is aligned with the mounting ring 2121, and then the elastic connecting sleeve 22 is pressed into the mounting ring 2121 by manually applying external force or extruding equipment and penetrates through the mounting ring 2121 along the axis, so that the elastic connecting sleeve 22 is mounted. In order to ensure that the elastic connecting sleeve 22 is firmly installed, in practical applications, a protruding edge may be disposed at an end of the elastic connecting sleeve 22 away from the sleeve connection portion 221, so that the protruding edge can abut against the outer wall of the connecting tube 211 after the elastic connecting sleeve 22 is installed, and plays a role in clamping and sealing. And the elastic connecting sleeve 22 and the mounting ring 2121 can also be in interference fit so as to ensure air tightness between the two.

More preferably, the connecting pipe 211 is provided with a locking ring 23, and the locking ring 23 is in threaded connection with the outer wall of the connecting pipe 211; when the elastic connecting sleeve 22 is sleeved on the connecting disc 212, the locking ring 23 can be pressed against the elastic connecting sleeve 22 by the knob, so that one side of the locking ring 23 is abutted against the elastic connecting sleeve 22. The knob of the locking ring 23 enables the locking ring 23 to move on the connection tube 211 along the axis of the connection tube 211. Therefore, when the elastic connecting sleeve 22 needs to be mounted, the locking ring 23 is first turned so that the locking ring 23 is away from the elastic connecting sleeve 22, so that a sufficient mounting space is left. After the elastic connecting sleeve 22 is sleeved on the connecting disc 212, the locking ring 23 is turned again so that the locking ring 23 extrudes the elastic connecting sleeve 22, and good air tightness between the elastic connecting sleeve 22 and the connecting disc 212 is ensured.

Further, the socket 221 is provided with anti-slip patterns. The anti-skid patterns can increase the friction force between the sleeving part 221 and the automobile oil pump 1 or the vacuumizing device 7, so that the connection of all the parts is firmer and tighter, and the working stability of the oil discharging device is improved.

Further, the socket 221 is detachably provided with a clip 24. The clamp 24 is used for locking the sleeving part 221 after the sleeving part 221 is sleeved with the automobile oil pump 1 or the vacuumizing device 7, so that the components can be firmly connected.

In a more preferred embodiment, the oil drain pipeline 3 is provided with a transparent window 5. The transparent window 5 can be arranged on the oil discharge pipeline 3 at intervals, and whether the oil discharge pipeline 3 is filled with fuel can be observed through the transparent window 5, so that workers can visually judge whether oil pumping is successful or not. The second control valve 8 is opened only when the operator observes through the transparent window 5 that the oil drain pipe 3 is already filled with fuel, in order to better pump oil.
