[0002] How to handle the used oil of the automobile is an important environmental protection concern. Since the used oil contains a large amount of metal particles, waste gas and residues, if not handled correctly, it may cause serious pollution to the soil and water source, and harm the health of the ecological system. Therefore, in the prior art, an extraction device is used to extract the used oil from the engine, gearbox and other devices, and then the extracted waste oil is centrally handled and then discharged.

[0003] However, even the used waste oil can be cleaned and reused, and the existing technology of treating all waste oil uniformly inevitably causes a lot of waste.

[0004] In addition, the device for receiving oil by gravity is usually placed at the bottom of the car, and the oil directly flows down the oil pipe into the storage device. However, different car chassis have different heights. For the same size oil receiving device, if the car chassis is too high, the oil receiving device cannot be placed directly on the ground and needs to be supported by external objects or directly held by hand; if the chassis is too low, it will affect the placement of the oil receiving device. This results in a small range of application of the oil receiving device. CONTENT OF THE INVENTION

[0005] Therefore, the present application provides an oil extraction and collection device to solve the problems of waste oil uniform treatment and small range of application of the oil receiving device in the prior art.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme:

[0007] An oil extraction and collection device, comprising an oil receiving disc, an oil outlet pipe and a liquid storage device, the upper end of the oil outlet pipe is connected with the oil receiving disc, the lower end is connected with the liquid storage device and a lower valve is arranged at the connecting section; the oil receiving disc is used to receive oil, the upper end of the oil receiving disc is open and the opening diameter of the upper end is larger than that of the lower end;

[0008] A collection barrel is sleeved outside the middle part of the oil outlet pipe, the collection barrel is made of transparent material, and the lower valve is below the collection barrel; an oil outlet hole is arranged on the side wall of the oil outlet pipe and is in communication with the collection barrel;

[0009] The oil outlet pipe is a telescopic pipe, and the telescopic position is above the collection barrel.

[0010] Optionally, the oil outlet pipe comprises an inner pipe and an outer pipe, the outer pipe is sleeved on the lower section of the inner pipe, the upper end of the outer pipe is further rotationally connected with a knob for limiting the sliding of the outer pipe; the upper end of the inner pipe is connected with the oil receiving disc, and the lower end of the outer pipe is connected with the liquid accumulator; the oil outlet hole, the lower valve and the collecting barrel are arranged on the outer pipe.

[0011] Optionally, the upper sealing ring is fixed on the inner circumferential wall of the upper end of the outer pipe, and the lower sealing ring is fixed on the outer circumferential wall of the lower end of the inner pipe.

[0012] Optionally, the side wall of the inner pipe is provided with a breathing hole, the breathing hole penetrates the side wall of the inner pipe, and the breathing hole is between the upper sealing ring and the lower sealing ring.

[0013] Optionally, the oil outlet hole is located at the position of the outer pipe close to the bottom of the collecting barrel.

[0014] Optionally, the lower valve is arranged at the position of the outer pipe close to the bottom of the collecting barrel.

[0015] Optionally, the collecting barrel is provided with a vacuum device mounting hole and an oil pumping hole.

[0033] Embodiment One

[0034] An oil extraction and collection device, with reference to Figure 1 and Figure 2 , comprising an oil receiving tray 1, an oil outlet pipe 2 and a reservoir 3, the upper end of the oil outlet pipe 2 is connected with the oil receiving tray 1, the lower end is detachably connected with the reservoir 3 and the connecting section is provided with a lower valve 4. The oil receiving tray 1 is used to receive oil, the upper end of the oil receiving tray 1 is open and the opening diameter is larger than that of the lower end, forming a funnel shape to receive oil.

[0035] The oil outlet pipe 2 is a telescopic pipe, comprising an inner pipe 5 and an outer pipe 6. The outer pipe 6 is slidingly sleeved on the lower section of the inner pipe 5, and the upper end of the outer pipe 6 is also rotatably connected with a knob 7 for limiting the sliding of the outer pipe 6, and the oil outlet pipe 2 is fixed by rotating the knob 7. The knob 7 belongs to mature prior art, so it is not described here. The upper end of the inner pipe 5 is connected with the oil receiving tray 1, the lower end of the outer pipe 6 is connected with the reservoir 3, and the lower valve 4 is arranged on the outer pipe 6.

[0036] In order to achieve the effect of saving labor, a handle is arranged on the knob 7, and anti-slip patterns are arranged on the handle to achieve the anti-slip effect.

[0037] The outer pipe 6 is sleeved with a collection bucket 8 outside the position close to the upper end, and the collection bucket 8 has a larger diameter for directly receiving oil. The lower valve 4 is below the collection bucket 8, which is used to open and close the passage of the outer pipe 6 to the reservoir 3, so that when the lower valve 4 is closed, the oil flowing out of the oil outlet pipe 2 will not flow into the reservoir 3. Correspondingly, an oil outlet hole 9 is formed in the side wall of the oil outlet pipe 2, which is in communication with the collection bucket 8, so that the oil in the oil outlet pipe 2 flows into the collection bucket 8 for collection.

[0038] Among them, the collection bucket 8 is made of transparent material, and a scale is arranged on the side wall. On the one hand, the transparent material is convenient for observing the color of the flowing oil, and the quality of the oil can be judged by observing the color and the number of impurities visible to the naked eye; on the other hand, the scale can more accurately measure the amount of oil.

[0039] In order to make the measurement result more accurate and reduce the error, the oil outlet hole 9 is arranged at a position close to the bottom of the collection bucket 8 on the outer pipe 6. At the same time, the position of the lower valve 4 is also arranged at a position close to the bottom of the collection bucket 8 on the outer pipe 6. By reducing the distance between the lower valve 4 and the oil outlet hole 9 as much as possible, the accumulation of oil between the two is reduced, so that the oil in the oil outlet pipe 2 can all flow directly into the collection bucket 8 for measurement.

[0040] In the implementation process, as the outer tube 6 and the inner tube 5 slide relative to each other, in order to prevent the residual engine oil on the inner tube 5 from polluting people when the length of the oil outlet pipe 2 is adjusted, the upper sealing ring 10 and the lower sealing ring 11 are arranged between the outer tube 6 and the inner tube 5. The upper sealing ring 10 is fixed to the inner circumferential wall of the upper end of the outer tube 6, and the lower sealing ring 11 is fixed to the outer circumferential wall of the lower end of the inner tube 5. Therefore, when the inner tube 5 or the outer tube 6 slides, the upper sealing ring 10 and the lower sealing ring 11 can scrape the residual engine oil between the inner tube 5 and the outer tube 6 clean.

[0041] Further, the breathing hole 12 is arranged on the side wall of the inner tube 5, penetrates the side wall of the inner tube 5, and is between the upper sealing ring 10 and the lower sealing ring 11. The annular space between the upper sealing ring 10 and the lower sealing ring 11 is communicated with the external space of the oil outlet pipe 2 through the breathing hole 12, so as to balance the air pressure of the two spaces and prevent a vacuum from being formed between the upper sealing ring 10 and the lower sealing ring 11 to cause the outer tube 6 to slide difficultly.

[0042] In other embodiments, the breathing hole 12 can also be arranged on the lower sealing ring 11 and penetrate the upper and lower end faces of the lower sealing ring 11, so as to also communicate the annular space between the upper sealing ring 10 and the lower sealing ring 11 with the external space of the oil outlet pipe 2.

[0043] In addition to the above oil receiving mode, another oil receiving mode is arranged on the basis of the device.

[0044] A vacuum device mounting hole 13 and an oil pumping hole 14 are arranged on the top of the collection barrel 8. In use, a vacuum environment between the collection barrel 8 and the oil outlet pipe 2 is established through the vacuum device. A pumping pipe is connected to the oil pumping hole 14, so that the engine oil can be pumped out by using the air pressure.

[0045] Correspondingly, an upper valve 15 is arranged on the inner tube 5 near the oil receiving disc 1. When the vacuum oil pumping mode is used, the upper valve 15 and the lower valve 4 need to be closed at the same time to avoid air circulation.

[0046] The implementation principle of the embodiment of the present application is that the vacuum oil pumping or the gravity oil receiving mode is selected according to the actual situation. When the vacuum oil pumping mode is selected, the upper valve 15 and the lower valve 4 need to be closed.

[0047] Before collecting the engine oil, the lower valve 4 is closed to prevent the engine oil from flowing directly into the liquid storage device 3 and being preliminarily collected in the collection barrel 8. The collection amount and quality of the engine oil are observed through the collection barrel 8. If the engine oil is seriously polluted, the waste liquid storage device 3 is connected to the lower end of the oil outlet pipe 2, and then the lower valve 4 is opened, so that the engine oil flows into the liquid storage device 3. If the engine oil can be cleaned and reused, the available engine oil storage device 3 is connected to the lower end of the oil outlet pipe 2, and then the lower valve 4 is opened, so that the engine oil is discharged into the storage device 3.

[0048] Embodiment Two

[0049] An oil extraction and collection device, referring to Figure 3 The difference between the embodiment and the embodiment one is the structure of the oil outlet pipe 2.

[0050] The oil outlet pipe 2 comprises an inner pipe 5 and an outer pipe 6, the outer pipe 6 is sleeved on the lower section of the inner pipe 5. Further, a sliding groove 16 is axially formed on the sidewall of the outer pipe 6, the sliding groove 16 penetrates the sidewall of the outer pipe 6. A nut 17 is further matched on the outer sidewall of the outer pipe 6 (the nut 17 can also be replaced by an arc-shaped gasket with a threaded hole), the nut 17 is located outside the sliding groove 16, and a screw 18 is threadedly matched in the nut 17, the screw 18 is fixed with the sidewall of the inner pipe 5 after penetrating the sliding groove 16. In this embodiment, only the upper sealing ring 10 is arranged, and the lower sealing ring 11 and the breathing hole 12 are not arranged.

[0051] The rotation position of the screw 18 is adjusted in advance, so that the nut 17 can abut against the sidewall of the outer pipe 6, and the sliding of the inner pipe 5 is limited by the cooperation of the nut 17, the screw 18 and the outer pipe 6. At the same time, the sliding groove 16 also has a guiding effect on the sliding of the inner pipe 5, so that the inner pipe 5 can slide along the axial direction.

[0052] Further, the sliding groove 16, the nut 17 and the screw 18 are uniformly and spacedly arranged in at least two groups along the circumference of the outer pipe 6, so as to fix the inner pipe 5 at different positions.

[0053] In the implementation process, the end of the screw 18 is fixed with the sidewall of the inner pipe 5, and the nut 17 abuts against the sidewall of the outer pipe 6 under the tightening action of the screw 18, so as to limit the sliding of the inner pipe 5. When adjusting the length of the oil outlet pipe 2, the inner pipe 5 is slid up and down with force, so that the nut 17 and the sidewall of the outer pipe 6 slide by friction, and the nut 17 and the sidewall of the outer pipe 6 can be fixed again under the action of friction after the inner pipe 5 is loosened, so as to limit the sliding of the inner pipe 5.

[0054] The technical features of the above embodiments can be combined arbitrarily (as long as the combination of the technical features does not exist contradictory). In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described; the embodiments which are not explicitly written should also be considered as the scope of the present disclosure.
