Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 5 The present invention provides a technical solution:

[0026] Example 1:

[0027] A hydraulic oil tank for easy oil stain cleaning includes an oil tank 1. A cover 2 is snap-fitted onto the top of the oil tank 1, allowing it to be easily fastened to the opening of the oil tank 1 and easily removed. A first oil pump 3 is fixedly mounted inside the cover 2. The first oil pump 3 is connected to an oil suction pipe 4 and an oil outlet pipe 5. The oil outlet pipe 5 movably passes through the cover 2. When the cover 2 is lifted and opened, the oil outlet pipe 5 passes through a corresponding through hole in the cover 2. When the first oil pump 3 is activated, the oil suction pipe 4 draws oil from inside the oil tank 1 and pumps the oil out through the oil outlet pipe 5. A vertical rod 6 is movably installed through the central slot. A handle 7 is fixedly installed at the top of the vertical rod 6. In this embodiment, the outer side of the handle 7 can be provided with anti-slip threads to prevent the operator from slipping during use. An airflow channel 701 is provided in the handle 7 and the vertical rod 6. A removable sealing plug 8 is provided at the top of the airflow channel 701. The sealing plug 8 has a certain elasticity and can block the airflow channel 701 to prevent it from being blocked by dust when not in use. A horizontal plate 9 is fixedly installed at the bottom of the vertical rod 6. The shape of the horizontal plate 9 can match the cross-sectional shape of the oil tank 1.

[0028] The horizontal plate 9 has a cavity 901, an oil storage channel 902, and an oil outlet 903. The oil storage channel 902 and the oil outlet 903 are connected. The horizontal plate 9 is equipped with an oil filter pipe device, which is connected to the oil storage channel 902. Therefore, after the oil is filtered and cleaned by the oil filter pipe device, it will flow to the oil storage channel 902 for discharge. An oil inlet cover 16 is fixedly installed on the top of the oil filter pipe device. The oil inlet cover 16 protrudes from the horizontal plate 9. A second oil pump 17 is installed on the oil inlet cover 16. When the second oil pump 17 is turned on, it will pump the oil in the oil tank 1 into the oil inlet cover 16, thereby guiding the flow of the oil. The oil filter pipe device can be driven by a vibration device to shake, which makes the filtration effect better and avoids clogging during filtration.

[0029] A first dustproof net 271 is installed at the outlet end of the oil storage channel 902, and a second dustproof net 272 is installed at the outlet end of the oil outlet 903. The functions of the first dustproof net 271 and the second dustproof net 272 are to prevent oil from back-contaminating the oil storage channel 902 and the oil outlet 903, respectively. Multiple soft brushes 28 are installed at the bottom of the horizontal plate 9. The soft brushes 28 can be used to clean the bottom of the oil tank 1. The cavity 901 is connected to the vent pipe 29, and the vent pipe 29 is connected to the air supply pipe 30. The air supply pipe 30 is tubular rather than flat, so the air supply pipe 30 will not block the connection between the oil storage channel 902 and the oil outlet 903. Multiple output pipes 31 are connected to the bottom of the air supply pipe 30. The output pipes 31 are connected to the inverted U-shaped operating chamber 32, and a first one-way valve 33 is installed in the output pipe 31. The first one-way valve 33 ensures that the gas in the air supply pipe 30 can only flow in one direction. The gas flows into the inverted U-shaped operating chamber 32 in one direction only, and cannot flow backwards. A sliding plate 34 is movably installed in one side of the inverted U-shaped operating chamber 32. The sliding plate 34 can move against the inner wall of the inverted U-shaped operating chamber 32 on that side. An installation rod 35 is fixedly installed at the bottom of the sliding plate 34, and a ball 36 is fixedly installed at the bottom of the installation rod 35. A third spring 37 is connected between the sliding plate 34 and the inner top wall of the inverted U-shaped operating chamber 32. The third spring 37 has good elasticity and can automatically return to its original state when no external force is applied. A second one-way valve 39 and a third dustproof net 40 are movably installed in the other side of the inverted U-shaped operating chamber 32. The second one-way valve 39 ensures that the gas inside the inverted U-shaped operating chamber 32 can only flow outwards through this side of the pipe in one direction and cannot flow backwards. The third dustproof net 40 prevents oil from flowing backwards into this side of the inverted U-shaped operating chamber 32.

[0030] Example 2:

[0031] A hydraulic oil tank for easy oil stain cleaning includes an oil tank 1. A cover 2 is snap-fitted onto the top of the oil tank 1, allowing it to be easily fastened to the opening of the oil tank 1 and easily removed. A first oil pump 3 is fixedly mounted inside the cover 2. An oil suction pipe 4 and an oil outlet pipe 5 are respectively connected to the first oil pump 3. The oil outlet pipe 5 movably passes through the cover 2. When the cover 2 is lifted and opened, the oil outlet pipe 5 passes through a corresponding through hole in the cover 2. When the first oil pump 3 is turned on, the oil suction pipe 4 can draw oil from inside the oil tank 1 and pump the oil out through the oil outlet pipe 5. A vertical rod 6 movably passes through the central slot of the cover 2. An elastic... The sealing ring 201 ensures an elastic seal between the filling vertical rod 6 and the tank cover 2, thereby preventing dust from the external environment from entering the interior of the oil tank 1. A handle 7 is fixedly installed at the top of the vertical rod 6. In this embodiment, the outer side of the handle 7 can be provided with anti-slip threads to prevent the operator from slipping during use. An airflow channel 701 is provided in the handle 7 and the vertical rod 6. A removable sealing plug 8 is provided at the top of the airflow channel 701. The sealing plug 8 has a certain elasticity and can block the airflow channel 701 to prevent it from being blocked by dust when not in use. A horizontal plate 9 is fixedly installed at the bottom of the vertical rod 6. The shape of the horizontal plate 9 can match the cross-sectional shape of the oil tank 1.

[0032] The horizontal plate 9 has a cavity 901, an oil storage channel 902, and an oil outlet 903. The oil storage channel 902 and the oil outlet 903 are connected. An oil filter pipe device is installed in the horizontal plate 9 and is connected to the oil storage channel 902. Therefore, after the oil is filtered and cleaned by the oil filter pipe device, it will flow to the oil storage channel 902 for discharge. An oil inlet cover 16 is fixedly installed on the top of the oil filter pipe device. The oil inlet cover 16 protrudes from the horizontal plate 9. The inner diameter of the oil inlet cover 16 gradually narrows at the end away from the upper hollow ring 10. This can prevent the oil stains falling on the filter screen 15 through the oil inlet cover 16 from flowing back out, making the cleaning more thorough. A second oil pump 17 is installed on the oil inlet cover 16. When the second oil pump 17 is turned on, it will pump the oil in the oil tank 1 to the oil inlet cover 16, thereby guiding the flow of the oil. The oil filter pipe device can be driven by a vibration device to shake, which makes the filtration effect better and avoids clogging during filtration.

[0033] A first dustproof net 271 is installed at the outlet end of the oil storage channel 902, and a second dustproof net 272 is installed at the outlet end of the oil outlet 903. The functions of the first dustproof net 271 and the second dustproof net 272 are to prevent oil from back-contaminating the oil storage channel 902 and the oil outlet 903, respectively. Multiple soft brushes 28 are installed at the bottom of the horizontal plate 9. The soft brushes 28 can be used to clean the bottom of the oil tank 1. The cavity 901 is connected to the vent pipe 29, and the vent pipe 29 is connected to the air supply pipe 30. Because it is tubular rather than flat, the air supply pipe 30 will not block the connection between the oil storage channel 902 and the oil outlet 903. Multiple output pipes 31 are connected to the bottom of the air supply pipe 30, and each output pipe 31 is connected to the inverted U-shaped operating chamber 32. A first one-way valve 33 is installed in each output pipe 31, ensuring that the gas in the air supply pipe 30 can only enter the inverted U-shaped operating chamber 32 in one direction and cannot flow backwards. A sliding plate 34 is movably installed in one side of the inverted U-shaped operating chamber 32. The sliding plate 34 can move against the inner wall of the inverted U-shaped operating cavity 32. A mounting rod 35 is fixedly installed at the bottom of the sliding plate 34, and a ball 36 is fixedly installed at the bottom of the mounting rod 35. A third spring 37 is connected between the sliding plate 34 and the inner top wall of the inverted U-shaped operating cavity 32. The third spring 37 has good elasticity and can automatically return to its original position when no external force is applied. A blocking block 38 is fixedly installed on the inner wall of the outlet at one end of the inverted U-shaped operating cavity 32 where the sliding plate 34 is located. The setting of 38 can prevent the sliding plate 34 from detaching from the inverted U-shaped operating cavity 32 during movement, thereby enabling the device to maintain stable operation. A second one-way valve 39 and a third dustproof net 40 are provided in the other side of the inverted U-shaped operating cavity 32. The setting of the second one-way valve 39 ensures that the gas inside the inverted U-shaped operating cavity 32 can only flow outward through this side of the pipe in one direction and cannot flow backward. The setting of the third dustproof net 40 can prevent oil from entering the side of the inverted U-shaped operating cavity 32 in reverse.

[0034] Example 3:

[0035] This embodiment, based on the above-described Embodiment 1 or Embodiment 2, further discloses and defines the specific structure of the oil filtration pipeline device. Specifically, the oil filtration pipeline device includes an upper hollow ring 10, which is fixedly embedded in the horizontal plate 9 near the cavity 901. An upper elastic connecting ring 11 is connected to the bottom of the upper hollow ring 10, and a connecting pipe 12 is connected to the bottom of the upper elastic connecting ring 11. The connecting pipe 12 is a rigid pipe, and a lower elastic connecting ring 13 is connected to the bottom of the connecting pipe 12. Both the upper elastic connecting ring 11 and the lower elastic connecting ring 13 have good elasticity and can maintain the stability of the connection at both ends when the connecting pipe 12 moves. The bottom of the 3 is connected to a lower hollow ring 14, which is fixed relative to the horizontal plate 9. A filter screen 15 is fixedly installed inside the connecting pipe 12. The function of the filter screen 15 is to filter and clean the dirt in the oil in the oil tank 1. A first spring 18 is connected to the side of the connecting pipe 12. The end of the first spring 18 away from the connecting pipe 12 is fixed to the limiting plate 19. When the connecting pipe 12 is pushed, the first spring 18 will be compressed. When the connecting pipe 12 loses its pushing force, the first spring 18 will automatically return to its original state and push the connecting pipe 12 back to its initial state. This causes the connecting pipe 12 to shake, preventing oil from clogging the filter screen 15 and making the filtration and cleaning of oil more smooth.

[0036] Example 4:

[0037] Based on the above-described Embodiment 1 or Embodiment 2, this embodiment further discloses and defines the specific structure of the vibration device. Specifically, the vibration device includes a rotary motor 20, a transmission rod 21 fixedly mounted on the output end of the rotary motor 20, and a cam 22 fixedly mounted on the transmission rod 21. After the rotary motor 20 is started, it can drive the cam 22 to rotate through the transmission rod 21. A mounting groove 221 is provided on the side of the cam 22, and a second spring 23 is connected in the mounting groove 221. A sliding plate 24 is connected in the second spring 23. The sliding plate 24 can slide in the mounting groove 221. The mounting groove 221 is a horizontal convex shape, so the sliding plate 24 will not detach from the mounting groove 221. An extension rod 25 is fixedly mounted on the side of the sliding plate 24 away from the second spring 23. A vibration ball 26 is fixedly mounted at the end of the extension rod 25. The vibration ball 26 can strike the connecting pipe 12, thereby causing the oil filter pipe device to be driven by the vibration device to shake, resulting in better filtration and preventing blockage during filtration.

[0038] Working principle:

[0039] When in use, the first oil pump 3 is turned on, the oil suction pipe 4 can draw oil from the inside of the oil tank 1 and pump the oil out through the oil outlet pipe 5.

[0040] After a period of use, if it is necessary to clean the oil stains in the oil inside the oil tank 1, the second oil pump 17 can be turned on. The second oil pump 17 pumps the oil into the oil inlet cover 16. The oil enters the oil filter pipe device through the oil inlet cover 16. The oil filter pipe device is equipped with a filter screen 15. The function of the filter screen 15 is to filter and clean the dirt in the oil in the oil tank 1. After filtration, the oil enters the oil storage channel 902 and flows out from the end opening of the oil storage channel 902 and the oil outlet 903 at the bottom of the horizontal plate 9. If the power of the second oil pump 17 is large, the oil flowing out will have a certain force, which can flush and clean the oil stains attached to the inner wall of the oil tank 1, making the oil stains cleaner more thorough.

[0041] During the cleaning process, the rotary motor 20 can be activated. The rotary motor 20 drives the cam 22 to rotate via the transmission rod 21, causing the vibrating ball 26 to be thrown out and impact the connecting pipe 12. When the connecting pipe 12 is pushed, the first spring 18 is compressed. When the connecting pipe 12 loses its pushing force, the first spring 18 automatically returns to its original state, causing the connecting pipe 12 to repeatedly shake, preventing oil from clogging the filter screen 15 and making the filtration and cleaning of oil more efficient. Furthermore, when the handle 7 presses down on the horizontal plate 9 via the vertical rod 6, the soft brush 28 at the bottom of the horizontal plate 9 contacts the bottom wall of the oil tank 1, thereby cleaning the oil from the bottom wall of the oil tank 1. During use, the sealing plug 8 can also be pulled out, allowing gas from the external environment to enter the cavity 901 through the airflow channel 701. The gas in 01 then enters the air supply pipe 30 through the vent pipe 29. The gas in the air supply pipe 30 finally enters the inverted U-shaped operating chamber 32 through the output pipe 31. When the ball 36 touches the bottom of the oil tank 1, as the horizontal plate 9 moves further down, the ball 36 drives the sliding plate 34 to slide upward through the mounting rod 35, thereby squeezing the gas in the inverted U-shaped operating chamber 32. This gas can only be discharged after passing through the second one-way valve 39. At this time, the bottom of the oil tank 1 can be blown by air and airflow, thereby stirring up the oil sludge settled at the bottom, so that the oil sludge can enter the oil inlet hood 16 for filtration and cleaning. Thus, the above-mentioned multiple devices work together to conveniently clean the oil inside the oil tank 1. Finally, the snap-fitted tank cover 2 can be lifted upward, and the horizontal plate 9 can be cleaned separately, making it more convenient to use.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
