Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and in particular to a small oil filter. Background Technology
[0002] Before the EV6 city public transport bus is put into operation, cooling oil needs to be injected into the air compressor for heat dissipation during bus operation. However, after the cooling oil has been injected into the air compressor for a period of time, the unused and residual cooling oil is prone to emulsification. The deteriorated oil will damage the air compressor. Therefore, the mechanic needs to regularly remove the emulsified oil and inject new oil.
[0003] When a bus motor or electrical component malfunctions or is damaged, the repairman needs to disassemble and repair it before reinstalling it on the bus. The repairman also needs to repeatedly test the condition of the components and wiring. For motors and electrical components that still have problems, the repairman needs to repeatedly disassemble, inspect, and repair them.
[0004] Bus batteries of all types will discharge due to their own discharge characteristics. When the bus is stopped, the anti-theft system and alarm device equipped on the vehicle are still working, and the battery will also discharge. If the battery voltage is low and the storage capacity is insufficient, resulting in the battery losing power, a repairman will need to use an external power source to charge the battery.
[0005] The shortcomings and deficiencies of existing technology: When mechanics periodically extract emulsified oil from the air compressor of EV6 buses, due to the low chassis and small gap between the air compressor and the vehicle floor, the air compressor must be disassembled to increase the working space before extraction. Disassembling the air compressor requires two mechanics working simultaneously, taking 40 minutes, increasing mechanics' working hours and the company's labor costs. Furthermore, the disassembly process easily leads to coolant spillage, causing oil stains between the vehicle body and the floor, which can corrode other vehicle components and cause environmental pollution. The spilled oil is also wasted, increasing company costs. When the bus's motor or electrical components malfunction or are damaged, after repair and reinstallation, if problems persist after testing the components and wiring, repeated disassembly, inspection, and repair are necessary. This repetitive work increases mechanics' working hours and the company's labor costs. Additionally, the vehicles remain in a maintenance state for extended periods, unable to operate, resulting in low vehicle utilization. Utility Model Content

[0022] Example
[0023] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a small oil filter, including an aluminum-layered metal outer casing 1, a first mounting base 2 fixedly connected to the top of the aluminum-layered metal outer casing 1, a bidirectional motor 3 fixedly connected to the top of the first mounting base 2, the bidirectional motor 3 using 24V DC power, a sealed cavity 4 fixedly connected to both ends of the bidirectional motor 3, an output shaft 5 fixedly connected to both output ends of the bidirectional motor 3, each output shaft 5 extending into the interior of the sealed cavity 4 and fixedly connected to an impeller 6, an oil suction pipe 7 fixedly connected inside the sealed cavity 4, and a first... The first installation chamber 8 contains an emulsified oil collection tank 9. Inside the emulsified oil collection tank 9 is a first oil delivery pipe 10, the other end of which extends into the sealed cavity 4. A solenoid valve 11 is installed inside the first oil delivery pipe 10. A second mounting base 12 is fixedly connected inside the first installation chamber 8. A new oil tank 13 is mounted on top of the second mounting base 12. A second oil delivery pipe 14 is installed inside the new oil tank 13, with one end of the second oil delivery pipe 14 extending into the emulsified oil collection tank 9. A third... The third oil supply pipe 15 extends to the sealed cavity 4 on the side away from the oil extraction pipe 7. A fourth oil supply pipe 16 is installed between the two sealed cavities 4. A two-way switch 17 is installed inside the fourth oil supply pipe 16. An aluminum filter screen 18 is installed inside the emulsified oil collection tank 9. A paper filter screen 19 is installed inside the emulsified oil collection tank 9 and below the aluminum filter screen 18. The output shaft 5 is driven to rotate by the two-way motor 3, and the output shaft 5 drives the impeller 6 to rotate, so that a vacuum is formed inside the sealed cavity 4, and the emulsified oil inside the bus is drawn into the sealed cavity 4 through the oil extraction pipe 7. The oil enters the emulsified oil collection tank 9 from the first oil supply pipe 10 inside the sealed cavity 4. Then, the emulsified oil is converted into usable oil through the aluminum filter screen 18 and the paper filter screen 19. The usable oil in the emulsified oil collection tank 9 is then drawn into the new oil tank 13 through the second oil supply pipe 14 using the bidirectional motor 3. The oil in the new oil tank 13 is then drawn into the sealed cavity 4 through the third oil supply pipe 15. Finally, the bidirectional switch 17 is opened, allowing the oil to enter the oil extraction pipe 7 through the fourth oil supply pipe 16. This enables the cooling oil to be recycled and reused, saving production costs for enterprises.
[0024] Furthermore, the aluminum-layered metal outer casing 1 is hinged to a first door 20. A solar thermal constant temperature plate 21 is installed on the outside of the first door 20. An inverter 22 is installed on the inside of the first door 20. A constant temperature controller 23 is installed on the inside of the first door 20. Heat-conducting plates 24 are installed at equal intervals on the inside of the first door 20. The temperature of the heat-conducting plates 24 is controlled by the constant temperature controller 23 to maintain a constant temperature inside the first installation chamber 8, ensuring the temperature of the cooling oil and preventing the oil from freezing due to low temperature, thus ensuring the oil quality.
[0025] Furthermore, a second mounting compartment 25 is provided inside the aluminum-layered metal outer casing 1. A charger 26 is installed inside the second mounting compartment 25. A bus battery charging port 27 for use with the charger 26 is also provided inside the aluminum-layered metal outer casing 1. A detector 28 is installed outside the aluminum-layered metal outer casing 1. A connecting cable is installed inside the detector 28, and its other end is electrically connected to the charger 26. A plug plate 29 is fixedly connected to the outside of the detector 28. A hollow plate 30 for use with the plug plate 29 is fixedly connected to the outside of the aluminum-layered metal outer casing 1. In the idle state, the detector... Instrument 28, in conjunction with insert plate 29, is inserted into the interior of hollow plate 30 for easy access. The interior of aluminum-layered metal outer box 1 is hinged with a second door 31. A protective cover 32 is fixedly connected to the top of aluminum-layered metal outer box 1. The protective cover 32 can protect the bidirectional motor 3 and play a certain role in dust and water protection. By connecting the two ends of the line to the bus battery charging port and the bus on-board battery charging port 27, the bus on-board battery can be charged. The detector 28 can detect the electrical and motor components and wiring of the bus after repair. The charger 26 can also supply power to the right half of the bidirectional motor 3.
[0026] In summary: When it is necessary to extract the emulsified engine oil from inside the bus, the bidirectional motor 3 is started. The bidirectional motor 3 drives the output shaft 5 to rotate, and the output shaft 5 drives the impeller 6 to rotate, creating a vacuum inside the sealed cavity 4. The emulsified engine oil inside the bus is then drawn into the sealed cavity 4 through the oil extraction pipe 7 and then enters the emulsified engine oil collection tank 9 through the first oil delivery pipe 10. Subsequently, the emulsified engine oil is converted into usable engine oil through the aluminum filter screen 18 and the paper filter screen 19. The bidirectional motor 3 then draws the usable engine oil from the emulsified engine oil collection tank 9 into the new oil tank 13 through the second oil delivery pipe 14. The engine oil from the new oil tank 13 is then drawn into the sealed cavity 4 through the third oil delivery pipe 15. Finally, the bidirectional switch 17 is opened, allowing... The engine oil enters the interior of the oil extraction pipe 7 through the fourth oil supply pipe 16, thereby enabling the cooling oil to be repeatedly recycled, saving production costs for the enterprise. The inverter 22 converts the sunlight absorbed by the solar constant temperature plate 21 into electrical energy, and then the constant temperature controller 23 controls the temperature of the heat conduction plate 24 to maintain a constant temperature inside the first installation chamber 8, ensuring the temperature of the cooling oil and preventing the oil from freezing due to low temperature, thus ensuring the oil quality. By connecting the two ends of the line to the bus battery charging port and the bus on-board battery charging port 27, the bus on-board battery can be charged. The detector 28 can detect the electrical and motor components and wiring of the bus after repair. The charger 26 can also supply power to the bidirectional motor 3 on the right half.
