[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1 to 4 As shown, this utility model embodiment provides an oil extraction device, which includes a first tube 10, a second tube 20, and a sealing part 30. The first tube 10 has a first oil extraction channel, and a first oil extraction port 11 is provided at the lower end of the first tube 10. The first oil extraction port 11 is connected to the first oil extraction channel. The second tube 20 is movably inserted into the first oil extraction channel along the axial direction of the first tube 10. The second tube 20 has a second oil extraction channel, and a second oil extraction port 21 is provided at the lower end of the second tube 20. The second oil extraction port 21 is connected to the second oil extraction channel. The sealing part 30 is provided at the lower end of the second tube 20. The sealing part 30 moves synchronously with the second tube 20 and has a sealing position that closes the first oil extraction port 11 and an open position that avoids the first oil extraction port 11.

[0029] The oil pumping device provided by the embodiment comprises a first pipe body 10, a second pipe body 20 and a sealing part 30. The first pipe body 10 is provided with a first oil pumping channel. The lower end of the first pipe body 10 is provided with a first oil pumping port 11. The first oil pumping port 11 is in communication with the first oil pumping channel. The second pipe body 20 is provided with a second oil pumping channel. The lower end of the second pipe body 20 is provided with a second oil pumping port 21. The second oil pumping port 21 is in communication with the second oil pumping channel. The second pipe body 20 is movably arranged in the first oil pumping channel along the axial direction of the first pipe body 10. The lower end of the second pipe body 20 is provided with the sealing part 30. The sealing part 30 can move synchronously with the second pipe body 20. When the sealing part 30 is in the sealing position, the first oil pumping port 11 can be closed. When the sealing part 30 is in the open position, the first oil pumping port 11 can be avoided. Specifically, the oil pumping device is placed in an oil drum. The second pipe body 20 is movably arranged in the first oil pumping channel along the axial direction of the first pipe body 10, so that the sealing part 30 is in the open position. Then, the first oil pumping port 11 of the first pipe body 10 and the second oil pumping port 21 of the second pipe body 20 are used to pump oil at the same time, so as to ensure the oil pumping efficiency of the oil pumping device. When the oil in the oil drum is in a lower position, the second pipe body 20 is moved in the first pipe body 10, so that the sealing part 30 is switched from the open position to the sealing position. The sealing part 30 can block the first oil pumping port 11. The second pipe body 20 is arranged in the first pipe body 10. The inner diameter of the second pipe body 20 is smaller than the inner diameter of the first pipe body 10. In this way, when the oil drum is tilted, the lower end of the second pipe body 20 can extend into the bottom of the oil drum. The vegetable oil remaining in the bottom of the oil drum can be avoided. A large amount of manpower can be avoided. The production cost is reduced.

[0030] As shown in Figure 1 , the oil pumping device comprises an operating part 40. The operating part 40 is arranged on the first pipe body 10. The operating part 40 is used to drive the second pipe body 20, so as to drive the sealing part 30 to switch between the sealing position and the open position when the second pipe body 20 moves. In the above structure, the operating part 40 is connected with the second pipe body 20. When the operating part 40 is controlled by the worker, the second pipe body 20 can move along the axial direction of the first pipe body 10, so as to drive the sealing part 30 to switch between the sealing position and the open position. The movement mode of the second pipe body 20 is simple and convenient to operate.

[0031] As shown in Figures 1 to 3As shown, the sealing part 30 includes an annular baffle 31 and a sealing ring 32. The annular baffle 31 is disposed on the second pipe body 20, and the sealing ring 32 is disposed on the annular baffle 31 and sleeved on the outer side wall of the second pipe body 20. When the sealing part 30 is in the sealing position, the lower surface of the sealing ring 32 is in sealing engagement with the annular baffle 31, and the upper surface of the sealing ring 32 is in sealing engagement with the first oil extraction port 11. With the above structure, an annular baffle 31 is disposed on the outer side wall of the second pipe body 20, and the sealing ring 32 is sleeved on the outer side wall of the second pipe body 20 and disposed on the annular baffle 31. When the sealing part 30 is in the sealing position, the lower surface of the sealing ring 32 is in sealing engagement with the annular baffle 31, and the upper surface of the sealing ring 32 can be in sealing engagement with the first oil extraction port 11, ensuring the sealing effect of the sealing ring 32.

[0032] In this embodiment, there is a gap between the outer wall of the second tube 20 and the inner wall of the first tube 10, and the lower end of the second tube 20 protrudes beyond the lower end of the first tube 10. The gap between the outer wall of the second tube 20 and the inner wall of the first tube 10 allows the second tube 20 to be movably inserted into the first tube 10. The lower end of the second tube 20 protruding beyond the lower end of the first tube 10 allows the vegetable oil in the oil drum to be completely sucked out when the oil drum is low, even with the inner diameter of the second tube 20 being smaller than that of the first tube 10, thus preventing waste.

[0033] In this embodiment, the oil extraction device further includes a one-way valve plate, which is disposed inside the second oil extraction port 21. By providing a one-way valve plate inside the second oil extraction port 21, the one-way valve plate can close the second oil extraction port 21 when the first pipe 10 and the second pipe 20 are extracted from the oil tank. This can prevent the vegetable oil in the second pipe 20 from flowing back and avoid waste of vegetable oil.

With the above structure, by pivotally mounting the lifting handle 41 on the first tube 10 and connecting the lower end of the pull rod 51 to the annular baffle 31, the lifting handle 41 and the pull rod 51 can be driven together to move the pull rod 51 along a direction parallel to the axis of the first tube 10 when the lifting handle 41 is pivoted. Furthermore, since the pull rod 51 is connected to the annular baffle 31, the sealing part 30 can be switched between a sealed position and an open position when the lifting handle 41 is pivoted and drives the pull rod 51 to move, thus simplifying the drive structure.

[0035] As Figure 1 shown in FIG. 1, the first pipe body 10 is provided with a mounting seat 12, the mounting seat 12 is provided with a first connecting rod 13, the first end of the first connecting rod 13 is hinged to the mounting seat 12, the second end of the first connecting rod 13 is hinged to the upper end of the pull rod 51, the pull handle 41 is drivingly connected with the first connecting rod 13 to drive the first connecting rod 13 to swing and drive the pull rod 51 to move along the axis direction parallel to the first pipe body 10.
