Description

Technical Field

[0001] This utility model relates to the field of oil mist separator technology, specifically a novel electronic oil mist separator. Background Technology

[0002] As is well known, automotive oil mist separators are mainly used in engines, transmissions, crankcases, and other components to separate lubricating oil mist, reduce oil consumption, and prevent oil mist from entering the intake system or polluting the environment. They are widely used in gasoline-powered vehicles, hybrid vehicles, and some high-performance engines.

[0003] A utility model patent with patent authorization announcement number CN202538543U discloses an oil mist separator, the purpose of which is to provide an oil mist separator in which the main body and the filter element are connected by threads. The oil mist separator includes a main body and an oil cup, a drain is provided at the bottom of the oil cup, the main body has an inlet and an outlet, and a filter element is provided on the inlet and outlet passages, and the filter element is connected to the main body by threads.

[0004] However, existing oil mist separators also have certain drawbacks. The old-style oil mist separators are mechanical, and the impeller is driven by air pressure to obtain the rotation speed. They perform high-speed mist separation of oil, water, and exhaust gas. When the driving air source is unstable, the impeller speed will be unstable, which will directly affect the atomization separation effect. Furthermore, there is a lack of detection of the impeller speed, which will affect the atomization separation accuracy. Utility Model Content

[0023] Please see Figure 1 , Figure 3A pad 200 is fixedly connected to the end face of the control board 104. The pad 200 contacts the motor housing 103. A locking hole 201 is provided on the end face of the pad 200. A movable plate 202 is slidably connected to the inner wall of the motor housing 103. A locking ball 204 is fixedly connected to the end face of the movable plate 202. The locking ball 204 is slidably connected to the locking hole 201. Through the cooperation of the locking hole 201 and the locking ball 204, the pad 200 can be locked in place, so that the control board 104 is in a stable position.

[0024] Please see Figure 1 , Figure 3 A spring 203 is fixedly connected to the end face of the movable plate 202. The other end of the spring 203 is fixedly connected to the motor housing 103. The movable plate 202 can be connected and used through the setting of the spring 203. Two pads 200 are provided. The two pads 200 are symmetrically distributed on the control plate 104. The pads 200 can be used in conjunction with the ball 204 for limiting.

[0025] Please see Figure 1 , Figure 4 A storage mechanism 3 is provided on both the motor housing 103 and the control board 104. The storage mechanism 3 includes a cable 300. The cable 300 is provided on the control board 104 and contacts the motor housing 103. A fixing frame 301 is fixedly connected to the rear side of the motor housing 103. A storage rod 302 is fixedly connected to the inner side wall of the fixing frame 301 and contacts the cable 300. A support plate 303 is slidably sleeved on the outer side of the storage rod 302 and contacts the cable 300. A second spring 304 is fixedly connected to the back of the support plate 303 and the other end of the second spring 304 is fixedly connected to the fixing frame 301. Through the action of the storage rod 302 and the support plate 303, the cable 300 can be stored and used.

[0026] Please see Figure 1 , Figure 4 There are two springs 304, which are symmetrically distributed on the support plate 303. The support plate 303 can be supported by the springs 304. The outer side of the storage rod 302 is connected to the screw cylinder 305 by thread. The back of the screw cylinder 305 is fixedly connected to the compression plate 306. The compression plate 306 contacts the cable 300. The cable 300 can be clamped by the screw cylinder 305 and the compression plate 306.

[0027] The specific implementation process of this utility model is as follows: In use, by pushing the control board 104 into the motor housing 103, the pad 200 is driven into the motor housing 103. When the pad 200 contacts the ball 204, the ball 204 can be pushed to move under the pressure of the rounded corner of the pad 200, so as to drive the moving plate 202 to move, causing the spring 203 to deform, and finally causing the ball 204 to slide along the surface of the pad 200. When the ball 204 slides into the hole 201, the spring 203 returns to its original deformation, so as to push the ball 204 into the hole 201, and the pad 200 is locked in place, so that the control board 104 is stable.

[0028] By passing the excess cable 300 used by the control board 104 through the motor housing 103 and wrapping the cable 300 around the outside of the storage rod 302, the cable 300 comes into contact with the support plate 303. Under the action of the second spring 304, the support plate 303 can be stably supported. Then, the screw barrel 305 is pushed to rotate. With the threaded connection, the screw barrel 305 can drive the extrusion plate 306 to move, so that the extrusion plate 306 comes into contact with the cable 300 and clamps the cable 300 to ensure the stable storage of the cable 300.

[0029] The control board 104 (ECU) sends a start signal to the brushless motor 105, controlling the speed of the brushless motor 105 to 10,000 revolutions per minute. The rotation speed pulse voltage is output through the rotor position signal of the brushless motor 105 to obtain real-time monitoring of the rotation of the impeller assembly 106, thereby achieving atomization precision control, realizing precise control of the speed of the brushless motor 105, real-time monitoring, and improving the fuel separation effect.
