[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example 1

[0020] like Figures 1 to 11 As shown, an intelligent energy-saving electronic oil pump includes an electronic oil pump body 1. A filter assembly 4 is provided at one end of the electronic oil pump body 1, and a pump cover 111 is provided at the front end of the electronic oil pump body 1.

The drive assembly is used to drive the electronic oil pump to enter the working chamber, and can also be used to discharge the oil. By precisely matching operating conditions through closed-loop feedback, energy efficiency is greatly improved and energy waste is avoided; the inner rotor 3 and the outer rotor 31 mesh to form a sealed working chamber, which circulates to complete the oil suction and discharge process, ensuring continuous and stable oil delivery and improving efficiency and pressure stability; the filter screen assembly 4 can be quickly disassembled and installed through the snap-fit ​​slot 41, the placement slot 411, the flip plate 424 and the hook 425, which is convenient for cleaning and replacement; the pump cover 111 and other structures ensure the sealing of the inner cavity, and combined with the filtration function of the filter screen assembly 4, it prevents leakage and impurities from entering, protects the oil pump and downstream system, and combines energy saving, high efficiency, easy maintenance and safety.

[0021] like Figures 1 to 5 As shown in the specific embodiment, a rear cover 11 is provided at the rear end of the electronic oil pump body 1. Multiple front-end fixing bolts 131 arranged in a circular pattern are provided between the pump cover 111 and the electronic oil pump body 1. A front-end sealing ring 162 is also provided between the pump cover 111 and the electronic oil pump body 1 to ensure the sealing performance of the electronic oil pump body 1. A filter screen assembly 4 is provided on the side wall of the pump cover 111 away from the electronic oil pump body 1. A filter screen sealing ring 16 is provided between the filter screen assembly 4 and the pump cover 111 to prevent leakage of the pumped oil. The filter screen assembly 4 and the pump cover 111 are connected by a locating pin. A rear-end sealing ring 161 is provided between the pump cover 111 and the electronic oil pump body 1 to ensure the sealing performance of the electronic oil pump body 1. Multiple rear-end fixing bolts 131 arranged in a circular pattern are also provided between the pump cover 111 and the electronic oil pump body 1. In this configuration, the rear cover 11 and pump cover 111 ensure the sealing of the inner cavity, providing a stable working environment for the moving parts. At the interface between the main body 1 and the outer rotor 31, the filter assembly 4 achieves multiple seals through the front sealing ring 16, the rear sealing ring 161 and the filter sealing ring 162, which not only prevents oil leakage but also effectively filters impurities, ensuring the cleanliness and safety of the oil pump and downstream system. Example 2

[0022] The difference between Embodiment 1 and this embodiment is that: Figures 1 to 5As shown, an intelligent energy-saving electronic oil pump has a controller mounting plate assembly 12 located at one end of the pump body 1 near the rear cover 11. A PCB board 14 is mounted on the side wall of the controller mounting plate assembly 12 away from the rear cover 11 within the inner cavity of the pump body 1. The PCB board 14 is used to detect the rotational speed of the drive assembly. In this configuration, the PCB board 14 on the controller mounting plate assembly 12 serves as the core control unit, undertaking the crucial functions of signal processing and control command transmission. When the PCB board 14 receives a working command, it immediately drives the motor rotor 21 mounted on the drive shaft 2 to rotate. The motor stator 22 on the outer ring of the motor rotor 21 cooperates with it to form a high-efficiency electromagnetic drive system, converting electrical energy into mechanical energy to drive the drive shaft 2 to rotate stably. This PCB board-dominated drive control mode is the core technological foundation for its intelligent energy-saving design. Compared to the open-loop control of traditional oil pumps, energy efficiency can be improved by more than 30%. The continuous rotation of the inner and outer rotors causes multiple working chambers to cycle through the process of "volume expansion - oil suction - volume reduction - oil discharge," thereby achieving oil... The continuous and stable delivery of the liquid; this pumping method based on volume change not only ensures the high efficiency of oil intake and discharge, but also effectively avoids oil backflow due to the precision of the gear meshing, further improving pumping efficiency and pressure stability; at the same time, the magnetic plate 26 on the drive shaft 2 and the PCB board 14 form a real-time sensing feedback system, accurately monitoring the speed, position and even load changes of the drive shaft. After the data is quickly processed by the adaptive algorithm built into the PCB board, the motor output power is adjusted in real time; this millisecond-level closed-loop intelligent control allows the oil pump to automatically reduce the speed under light load and accurately increase the power under heavy load, completely avoiding the energy waste of "overpowered motor," and long-term operation can help users reduce electricity costs by more than 40%, showing significant advantages in energy saving.

[0023] like Figures 4 to 7 As shown, in a specific embodiment, the drive assembly includes a drive shaft 2, which is mounted on the electronic oil pump body 1. An inner rotor 3 is mounted at one end of the drive shaft 2, and a motor rotor 21 is also mounted on the drive shaft 2. A motor stator 22 is mounted around the outer ring of the motor rotor 21, and the motor stator 22 is located within the electronic oil pump body 1. This configuration ensures that when the PCB board 14 receives a working command, it immediately drives the motor rotor 21 mounted on the drive shaft 2 to rotate. The motor stator 22 on the outer ring of the motor rotor 21 cooperates with it to form a high-efficiency electromagnetic drive system, converting electrical energy into mechanical energy to drive the drive shaft 2 to rotate stably. This PCB board-dominated drive control mode is the core technology foundation for achieving intelligent energy saving, and compared to the open-loop control of traditional oil pumps, energy efficiency can be improved by more than 30%.

[0024] like Figures 4 to 7As shown, a magnetic sheet 26 is further provided at one end of the drive shaft 2 near the controller mounting plate assembly 12. The magnetic sheet 26 and the PCB board 14 on the controller mounting plate assembly 12 cooperate with each other. In this configuration, it is ensured that when the inner rotor 3 and the outer rotor 31 work together, the oil first enters the pump body through the filter assembly 4 and is pressurized and transported under the action of the volume change of the inner and outer rotors. The PCB board 14 continuously optimizes the operating state of the motor rotor 21 based on the feedback information from the magnetic sheet 26, so that the speed of the drive shaft 2 is always precisely matched with the pump oil demand. This design not only allows the oil pump to maintain high efficiency under different operating conditions, but also minimizes mechanical loss through the low-friction design of the inner and outer rotor structures, further enhancing the energy-saving effect. Example 3

[0025] The difference between Embodiment 2 and this embodiment is that: Figures 7 to 11 As shown, an intelligent energy-saving electronic oil pump has a drive shaft 2 rotatably mounted on a pump cover 111. The inner cavity of the pump cover 111 near the filter assembly 4 has multiple circumferentially distributed sliding slots 17, each symmetrically arranged in pairs. A sliding plate 171 is slidably mounted between each pair of sliding slots 17, and each sliding plate 171 is circumferentially distributed. A return spring 172 is provided inside each sliding slot 17, with the other end of each return spring 172 mounted on a sliding plate 171. In this configuration...

[0026] like Figures 7 to 11 As shown, in a specific embodiment, each hook 425 is adapted to the sliding plate 17, and each flip plate 424 has a rotating rod 422 at both ends, with each pair of rotating rods 422 being symmetrical. Each pair of opposite ends of each rotating rod 422 has a bearing 421, and each pair of bearings 421 is symmetrical. Each pair of opposite ends of each bearing 421 has a fixing plate 421, and each fixing plate 421 is respectively mounted on the filter assembly 4. The filter assembly 4 has multiple circumferentially distributed pins 44, each pin 44 being adapted to the flip plate 424. In this configuration...

[0027] like Figures 4 to 7As shown, the outer rotor 31 is further fitted into the inner cavity of the electronic oil pump body 1. In this configuration, the installation position of the outer rotor 3 is determined to ensure that when the drive shaft 2 drives the inner rotor 3 to rotate, the inner rotor 3 and the outer rotor 31 of the outer ring mesh with each other due to the eccentricity and different number of teeth, forming multiple sealed working chambers. During the oil suction stage, as the inner rotor rotates, the volume of a certain working chamber gradually increases, forming a local vacuum inside. At the same time, it ensures that when the inner rotor and the outer rotor continue to rotate, the multiple working chambers circulate to complete the process of "volume expansion - oil suction - volume reduction - oil discharge", thereby achieving continuous and stable oil delivery. This pumping method based on volume change not only ensures the high efficiency of oil suction and discharge, but also effectively avoids oil backflow due to the precision of tooth meshing, further improving pumping efficiency and pressure stability.

[0028] The implementation principle of the intelligent energy-saving electronic oil pump of the present invention is as follows: The operation of an intelligent energy-saving electronic oil pump begins with the controller fixed board assembly 12, on which the PCB board 14 serves as the core control unit, undertaking the key functions of signal processing and control command transmission. When the PCB board 14 receives the working command, it immediately drives the motor rotor 21 mounted on the drive shaft 2 to rotate. The motor stator 22 on the outer ring of the motor rotor 21 cooperates with it to form a high-efficiency electromagnetic drive system, converting electrical energy into mechanical energy and driving the drive shaft 2 to rotate stably. This drive control mode dominated by the PCB board is the core technology cornerstone for its intelligent energy saving. Compared with the open-loop control of traditional oil pumps, the energy efficiency can be improved by more than 30%. When the drive shaft 2 drives the inner rotor 3 to rotate, the inner rotor 3 and the outer rotor 31 of the outer ring mesh with each other due to the eccentricity and different number of teeth, forming multiple sealed working chambers. During the oil intake stage, as the inner rotor rotates, the volume of a certain working chamber gradually increases, and a local vacuum is formed inside. At this time, the oil is filtered by the filter screen assembly 4 under the action of external atmospheric pressure and is drawn into the enlarged working chamber through the oil pump suction port. During the oil discharge stage, when the working chamber rotates with the inner rotor to the position connected to the oil pressure port, the volume of the working chamber begins to gradually decrease, the oil in the chamber is squeezed, the pressure continues to rise, and finally it is discharged through the oil pressure port and transported to the downstream oil system. The continuous rotation of the inner and outer rotors allows multiple working chambers to cycle through the process of "volume expansion - oil suction - volume reduction - oil discharge," thus achieving continuous and stable oil delivery. This pumping method based on volume change not only ensures high efficiency in oil intake and discharge but also effectively prevents oil backflow due to the precision of the tooth meshing, further improving pumping efficiency and pressure stability. At the same time, the magnetic plate 26 on the drive shaft 2 and the PCB board 14 form a real-time sensing feedback system, accurately monitoring the speed, position, and even load changes of the drive shaft. After the data is quickly processed by the adaptive algorithm built into the PCB board, the motor output power is adjusted in real time. This millisecond-level closed-loop intelligent control allows the oil pump to automatically reduce its speed under light load and precisely increase its power under heavy load, completely avoiding the energy waste of "overpowered motors." Long-term operation can help users reduce electricity costs by more than 40%, demonstrating significant advantages in energy saving. The rear cover 11 and pump cover 111 ensure the sealing of the inner cavity, providing a stable working environment for the moving parts; at the interface between the body 1 and the outer rotor 31, the filter assembly 4 achieves multiple seals through the front sealing ring 16, the rear sealing ring 161 and the filter sealing ring 162, which not only prevents oil leakage, but also effectively filters impurities, ensuring the cleanliness and safety of the oil pump and downstream system. When the inner rotor 3 and the outer rotor 31 work together, the oil first enters the pump body through the filter screen assembly 4, and is pressurized and transported under the action of the volume change of the inner and outer rotors. The PCB board 14 continuously optimizes the operating state of the motor rotor 21 based on the feedback information of the magnetic sheet 26, so that the speed of the drive shaft 2 is always precisely matched with the oil demand of the pump. This design not only allows the oil pump to maintain high efficiency under different working conditions, but also minimizes mechanical loss through the low-friction inner and outer rotor structure, further enhancing the energy-saving effect. Simultaneously, when it is necessary to disassemble the filter assembly 4, insert the pin 44 inward. This pin 44 will then press against one side wall of the bottom of the flip plate 424, allowing the flip plate 424 to rotate with the assistance of the rotating rod 422. When the flip plate 424 rotates, the hook 425 flips, separating it from the sliding plate 171. At this point, the operator can pull the filter assembly 4 outward to remove it. (Simultaneously, during installation, insert the filter assembly 4 into the pump cover 111.) Therefore, the snap-fit ​​slot 41 on the filter assembly 4 can fit into the sliding plate 171. When the filter assembly 4 is inserted, the sliding plate 171 can press the inclined surface of the hook 425, causing the hook 425 to flip. After the filter assembly 4 and the pump cover 111 are inserted, the hook 425 is reset with the assistance of the torsion spring 423 and can hook onto the sliding plate 171, thus achieving locking between the filter assembly 4 and the pump cover 111. This facilitates the disassembly and replacement of the filter assembly 4.
