Description

Technical Field

[0001] This utility model relates to the field of engine oil collection technology, specifically to an engine oil collection and recovery device that is easy to adjust in height. Background Technology

[0002] In the daily use and maintenance of automobiles, engine oil change is a core maintenance step to ensure normal engine operation and extend vehicle lifespan. During oil change operations, the efficient collection and recovery of drained oil not only affects the efficiency of the maintenance work but also directly impacts the cleanliness of the working environment and resource recycling. Therefore, efficient and practical oil collection and recovery devices have become one of the key pieces of equipment in the automotive repair and maintenance field. A search revealed Chinese patent application number 202420554359.2, which discloses an oil collection and recovery device. This device innovatively employs an active extraction method to collect and recover engine oil from inside a vehicle through the coordinated operation of a vacuum pump and an adsorption unit. This effectively shortens the waiting time required for the natural drainage of traditional engine oil, significantly improving the overall efficiency of automotive oil maintenance and repair, and demonstrating a certain advantage in optimizing operational efficiency. Furthermore, the oil control placement unit designed in this patent not only provides a stable storage location for the adsorption unit when it is idle, preventing damage or loss of components, but also allows for secondary recovery of the engine oil adhering to the surface of the adsorption unit after use, further improving the oil collection and recovery rate and laying the foundation for the widespread application of the device. However, in actual automotive repair and maintenance scenarios, this patented device still has significant limitations and struggles to meet diverse oil collection needs. Firstly, it relies solely on the adsorption section for oil collection, resulting in a relatively simplistic method. During engine oil changes or maintenance, the oil is not always in an adsorbable state; it often drips due to component disassembly or gravity. The device lacks a dedicated oil collection tray to catch this dripping oil, leading to ineffective collection, wasted oil resources, potential site contamination, and increased cleaning costs, thus reducing its practicality. Secondly, the patented integrated filter section lacks a disassembly mechanism, making it difficult to clean accumulated impurities after prolonged use. As impurities accumulate, the filter's effectiveness decreases, potentially leading to blockages and disrupting the normal oil collection and recovery process. This increases maintenance difficulty and reduces worker efficiency, hindering long-term stable operation in actual repair and maintenance work.

[0003] Therefore, there is a need for an engine oil collection and recovery device that is easy to adjust in height to solve the above-mentioned problems. Utility Model Content

It has the advantages of being height-adjustable to adapt to different vehicle models, capable of dual oil collection (collecting dripping oil + actively adsorbing oil), and having an easy-to-disassemble and clean filter component. This solves the problems of existing devices having limited collection methods (unable to collect dripping oil), difficulty in adapting to different vehicle engine heights leading to low practicality, and difficulty in cleaning the integrated filter component later, which is not conducive to the use of operators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an engine oil collection and recovery device with easy lifting and adjustment, comprising a trolley, a collection bucket fixedly connected to the top of the trolley, an inlet opening at the top of the collection bucket, a support frame fixedly connected to the top of the inner wall of the collection bucket, and the support frame being directly below the inlet opening, a connecting seat fixedly connected to the top of the inlet opening, an embedding groove opening at the top of the connecting seat, a filter funnel being engaged inside the embedding groove, a pressure cap threadedly connected to the surface of the connecting seat, and the pressure cap cooperating with the filter funnel, a connecting cover threadedly connected to the top of the pressure cap, and an adsorption hose connected to the top of the connecting cover, and an installation device fixedly connected to the top of the trolley.

[0015] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4As shown, this utility model provides an engine oil collection and recovery device that is easy to lift and adjust. It includes a trolley 1, a collection bucket 2 fixedly connected to the top of the trolley 1, an inlet 3 at the top of the collection bucket 2, a support frame 4 fixedly connected to the top of the inner wall of the collection bucket 2, and the support frame 4 is located directly below the inlet 3. A connecting seat 5 is fixedly connected to the top of the inlet 3, and an embedding groove is formed at the top of the connecting seat 5. A filter hopper 6 is fitted inside the embedding groove. The support frame 4 has a ring structure, with its top ring surface completely fitting against the bottom edge of the filter hopper 6 for uniform support. A pressure cap 7 is threadedly connected to the surface of the connecting seat 5, and the pressure cap 7 works in conjunction with the filter hopper 6. A connecting cover 8 is threadedly connected to the top of the pressure cap 7, and an adsorption hose 9 is connected to the top of the connecting cover 8. The top of the trolley 1 is fixedly connected to... The device has a mounting base, with sliding columns 10 fixedly connected to the four corners of the top of the mounting base. A fixing plate is fixedly connected to the top of the four sliding columns 10. A mounting block is fixedly connected to the surface of the sliding column 10. A lifting motor 11 is fixedly connected inside the mounting block. The output shaft of the lifting motor 11 is fixedly connected to a lead screw 12 via a coupling. The top of the lead screw 12 is rotatably connected to the fixing plate. A lifting block 13 is threadedly connected to the surface of the lead screw 12. The lifting block 13 is slidably connected to the sliding column 10. A support frame 14 is fixedly connected to the surface of the lifting block 13. A collection hopper 15 is fixedly connected to the top of the support frame 14. A collection pump 16 is fixedly connected to the top of the mounting base. The output end of the collection pump 16 is connected to the collection bucket 2. The input end of the collection pump 16 is connected to a collection hose 17. The collection hose 17 is connected to the collection hopper 15.

[0017] refer to Figure 1 and Figure 2 The surface of the collection bucket 2 is provided with an observation window, and the top of the trolley 1 is provided with a drain port. The bottom of the drain port is connected to a drain valve 18, and the output end of the drain valve 18 is connected to a discharge channel 19.

[0018] As a technical optimization of this utility model, the amount of oil collected in the collection tank 2 can be observed in real time through the observation window, which makes it convenient for staff to understand the working status of the device and the oil storage status in a timely manner. The cooperation of the drain port, drain valve 18 and drain channel 19 allows the oil in the collection tank 2 to be discharged to the designated storage container through the drain channel 19 after the oil collection is completed by opening the drain valve 18, realizing convenient transfer of oil. The operation is simple and controllable.

[0019] Referring to the figure, a guide surface is provided at the bottom of the inner wall of the collection hopper 15, and a snap-fit ​​groove 20 is provided at the center of the collection hopper 15. A filter funnel 21 is snapped into the inside of the snap-fit ​​groove 20, and the filter funnel 21 is connected to the collection hose 17.

[0020] As a technical optimization of this utility model, the design of the guide surface can guide the dripping oil collected in the collection hopper 15 to converge towards the center, avoiding oil residue in the collection hopper 15; the filter funnel 21 is snapped onto the collection hopper 15 through the snap-fit ​​groove 20, which can not only filter the dripping oil and remove impurities to ensure the purity of the oil entering the collection bucket 2, but also facilitate the later disassembly of the filter funnel 21 for cleaning or replacement, making maintenance highly convenient.

[0021] refer to Figure 1 The top of the collection bucket 2 is fixedly connected to a threaded ring 22, and the inside of the threaded ring 22 is connected to a sealing cap 23, which is used in conjunction with the pressure cap 7. The top of the collection bucket 2 is connected to a placement port, and the inside of the placement port is fixedly connected to a one-way valve, which is used in conjunction with the adsorption hose 9.

[0022] As a technical optimization of this utility model, the sealing cap 23 is connected to the collection bucket 2 via the threaded ring 22. When the device is not in use, the sealing cap 23 can be closed on the outside of the pressure cap 7 to protect the connecting seat 5, filter bucket 6, pressure cap 7 and other components, preventing dust and impurities from entering. The placement port and one-way valve provide a spare connection port for the adsorption hose 9, and the connection position can be flexibly selected according to the actual oil adsorption needs. The one-way valve can prevent the oil or gas in the collection bucket 2 from overflowing in the reverse direction, ensuring the stability of the adsorption process.

[0023] refer to Figure 1 and Figure 2 The top of the collection tank 2 is connected to a balancing valve 24, and a filter screen is fixedly connected to the output end of the balancing valve 24.

[0024] As a technical optimization of this utility model, the air pressure inside the collection tank 2 can be adjusted in real time by the balance valve 24. When the collection pump 16 delivers engine oil to the collection tank 2 or the suction hose 9 absorbs engine oil into the collection tank 2, the balance valve 24 can balance the air pressure difference between the inside of the tank and the outside, so as to avoid the normal collection and delivery of engine oil due to air pressure imbalance. The filter screen can prevent dust and impurities in the outside air from entering the collection tank 2 through the balance valve 24, so as to ensure the cleanliness of the inside of the collection tank 2 and avoid secondary contamination of the engine oil.

[0025] refer to Figure 1 A baffle is fixedly connected to the top of the cart 1, and a cushioning pad is fixedly connected to the surface of the baffle. The cushioning pad is in contact with the collection bucket 2. A battery 25 is fixedly connected to the surface of the baffle, and a controller 26 is fixedly connected to the top of the battery 25. A human-machine interface is provided on the surface of the controller 26.

[0026] As a technical optimization of this utility model, the combination of baffle and buffer pad can provide lateral support and buffer protection for the collection tank 2, reducing the shaking of the collection tank 2 during the movement of the device and preventing oil spillage or damage to the collection tank 2 due to shaking; the battery 25 provides power support for electrical components such as the lifting motor 11, the collection pump 16, and the controller 26, ensuring that the device can work normally without an external power source, improving the mobility and adaptability of the device to different usage scenarios; the human-machine interface of the controller 26 makes it easy for operators to set the lifting height of the lifting motor 11 and control the start and stop of the collection pump 16, reducing the difficulty of operation and improving work efficiency.

[0027] The working principle and usage process of this utility model are as follows: When using this engine oil collection and recovery device that is easy to lift and adjust, firstly, the device is moved to the designated position of the car to be maintained by the trolley 1. Then, the human-machine interface on the surface of the controller 26 is operated, and the battery 25 supplies power to the lifting motor 11. After the lifting motor 11 is started, its output shaft drives the lead screw 12 to rotate through the coupling. When the lead screw 12 rotates, the lifting block 13 connected to it slides along the slide column 10. The lifting block 13 drives the support frame 14 fixed on the surface to rise and fall synchronously, thereby adjusting the collection bucket 15 fixed at the top of the support frame 14 to a suitable height directly below the dripping engine oil of the car. If it is necessary to use the adsorption hose 9 to adsorb the oil, the adsorption hose can be... One end of the suction hose 9 extends into the engine oil pan of the car engine. Then, the balance valve 24 is activated to extract air from the collection bucket 2, creating negative pressure in the suction hose 9. This allows the engine oil to flow through the suction hose 9 into the connecting cover 8, then into the pressure cap 7, and finally through the connecting seat 5 into the filter funnel 6. The filter funnel 6 performs preliminary filtration of the engine oil. The filtered oil then flows into the collection bucket 2 through the inlet 3. The support frame 4 fixed to the top of the inner wall of the collection bucket 2 provides auxiliary support for the filter funnel 6. When engine oil drips from the car engine, the collection bucket 15 catches the dripping oil. The guide surface at the bottom of the inner wall of the collection bucket 15 guides the oil towards the center. The oil then enters the filter funnel 21, which is engaged in the locking groove 20 at the center of the collection bucket 15. The filter funnel 21 further filtrations the oil. After filtration, the collection pump 16 on top of the mounting base (fixed to the top of the trolley 1) is activated. The collection pump 16 draws the filtered oil from the filter funnel 21 into the collection pump 16 through the collection hose 17 connected to its input end, and then delivers it to the collection bucket 2 through the output end of the collection pump 16. During the collection process, the amount of oil collected in the collection bucket 2 is observed in real time through the observation window on the surface of the collection bucket 2. At the same time, the balance valve 24 connected to the top of the collection bucket 2 adjusts the internal air pressure of the collection bucket 2 in real time. The filter screen fixed at the output end of the balance valve 24 prevents external impurities from entering the collection bucket 2. When the oil collection is complete, if it is necessary to drain the oil, open the drain valve 18 connected to the bottom of the drain port on the top of the trolley 1. The oil in the collection bucket 2 flows into the drain through the drain port and the drain valve 18. The liquid valve 18 output end is connected to the discharge channel 19, and then the liquid is discharged to the designated storage container through the discharge channel 19. If the device is not in use for the time being, the sealing cap 23 connected to the threaded ring 22 (fixed on the top of the collection bucket 2) can be rotated to make the sealing cap 23 cooperate with the pressure cap 7 to cover the components such as the connecting seat 5, filter funnel 6, and pressure cap 7. At the same time, the filter funnel 21 in the collection bucket 15 and the filter funnel 6 on the connecting seat 5 can be disassembled for cleaning. After cleaning, they can be reassembled according to the original structure. Alternatively, the other end of the adsorption hose 9 can be directly inserted into the placement port for temporary placement (without the need to use the sealing cap 23 for sealing). The one-way valve allows the residual oil in the adsorption hose 9 to flow back into the collection bucket 2 for the next use.

[0028] It should be noted that the lifting motor 11 disclosed above can be, but is not limited to, the 60BYG series or 86BYG series, paired with a corresponding driver. It is suitable for driving the lead screw 12 to rotate, thereby causing the lifting block 13 to slide along the slide column 10, and thus adjusting the height of the collection hopper 15. It features stable speed, sufficient torque, and high positioning accuracy, and can accurately adapt to the height requirements of the oil dripping position of different engine models. The collection pump 16 can be, but is not limited to, a micro gear pump (such as the DC40 series) or a small self-priming pump (such as the ZCB series), and is suitable for collecting the oil in the collection hopper 15 after it has been filtered by the filter funnel 21. The oil is delivered to the collection tank 2, featuring small size, controllable flow rate, and resistance to oil corrosion, ensuring the stability and efficiency of oil delivery. The controller 26 can use a PLC control module (such as Siemens S7-200SMART or Mitsubishi FX3U series), paired with a human-machine interface (such as Weintek TK6071IP or Kunlun Tongtai TPC7062Ti), suitable for setting the lifting height of the lifting motor 11 and controlling the start and stop of the collection pump 16. It can also reserve a data display interface to provide feedback on the device's operating status. The battery 25 can be, but is not limited to, a 12V lead-acid battery. (e.g., 6-QW-45 series) or 12V lithium battery (e.g., lithium iron phosphate 12V20Ah series) provides independent power supply for the lifting motor 11, collection pump 16, and controller 26. It features sufficient capacity, stable charge / discharge cycles, and compatibility with the power requirements of vehicle-mounted equipment, ensuring normal operation of the device when disconnected from an external power source. The balance valve 24 can be, but is not limited to, a miniature one-way balance valve (e.g., HV series or BV series) to adjust the internal air pressure of the collection tank 2, preventing pressure imbalance during oil collection from affecting delivery efficiency. It features rapid response and good sealing, and its output end... The filter screen can be, but is not limited to, a 100-200 mesh stainless steel filter screen, which effectively blocks external dust and impurities from entering the collection tank 2; the drain valve 18 can be, but is not limited to, a miniature solenoid valve (such as a 2W series normally closed solenoid valve) or a manual ball valve (such as a Q11F series), which is adapted to control the oil in the collection tank 2 to be discharged through the drain channel 19. The solenoid valve can be automatically controlled by the controller 26, while the manual ball valve has the characteristics of simple operation and low failure rate, which can meet the draining needs under different operating scenarios. The controller 26 controls the operation of each electrical appliance using the circuit connection and program control methods commonly used in the existing technology.
