The output shaft end of the motor 4 drives the rotating shaft 2 to rotate, and at this time the rotating shaft 2 drives the fan blade 3 to rotate. The rotation of the fan blade 3 causes the air to start flowing, thereby cooling the object, an oil-containing bearing body 8 is fixedly embedded on one side of the motor cover 6, a plurality of oil injection holes 7 are opened on the outer side of the oil-containing bearing body 8, and an oil injection assembly 5 is arranged on one side of the motor cover 6.

[0029] The oil filling assembly 5 includes a fixing frame 51 and a pressure plate 54. The bottom of the pressure plate 54 is rotatably connected with a screw rod 55. An oil storage chamber 53 is provided inside the fixing frame 51. Lubricating oil is injected into the oil storage chamber 53. The turntable 52 is rotated regularly. At this time, the turntable 52 drives the screw rod 55 to rotate. When the screw rod 55 is threadedly connected to the bottom of the fixing frame 51, the pressure plate 54 drives the sealing ring 56 to slide upward on the inner wall of the oil storage chamber 53. A sealing ring 56 is bonded to the outside of the pressure plate 54. A turntable 52 is fixed at one end of the bottom of the screw rod 55. The outside of the sealing ring 56 is seamlessly slidably connected to the inner wall of the oil storage chamber 53. A filling groove 59 and an oil delivery pipe 58 are respectively provided inside the motor cover 6. The oil-containing bearing body 8 is located inside the filling groove 59. The filling groove 59 and the oil delivery pipe 58 is connected, and a one-way valve 57 is installed on the oil pipe 58. The pressure plate 54 squeezes the lubricating oil on the inner wall of the oil storage chamber 53 and injects the lubricating oil into the inner side of the oil pipe 58 and the filling groove 59. The lubricating oil is injected into the interior of the oil-containing bearing body 8 through the oil filling hole 7. The outer side of the screw rod 55 is threadedly connected to the bottom side of the fixing frame 51. The oil storage chamber 53 is connected to the oil pipe 58. The outer side of the fixing frame 51 is fixedly inserted into the bottom side of the motor cover 6.

Timely replenishment of lubricating oil can reduce the friction and wear of the oil-containing bearing body 8, thereby extending the service life of the oil-containing bearing body 8. The shape of the fixing frame 51 is cylindrical.

[0030] Working principle: When the cooling fan is in use, the switch is pressed to start the motor 4, and the output shaft end of the motor 4 drives the shaft 2 to rotate. At this time, the shaft 2 drives the fan blades 3 to rotate. The rotation of the fan blades 3 causes the air to flow, thereby cooling the object. When the shaft 2 rotates, the outer side of the oil-containing bearing body 8 contacts the inner wall of the motor cover 6, and at the same time, the inner wall of the oil-containing bearing body 8 contacts the outer side of the shaft 2;

[0031] When the lubricating oil on the surface of the oil-containing bearing body 8 becomes less, the staff will regularly rotate the turntable 52, and the turntable 52 will drive the screw 55 to rotate. When the screw 55 is threadedly connected to the bottom of the fixing frame 51, the pressure plate 54 drives the sealing ring 56 to slide upward on the inner wall of the oil storage chamber 53. The pressure plate 54 squeezes the lubricating oil on the inner wall of the oil storage chamber 53 and injects the lubricating oil into the inner side of the oil delivery pipe 58 and the filling groove 59. The lubricating oil is injected into the interior of the oil-containing bearing body 8 through the oil filling hole 7. At this time, the oil-containing bearing body 8 can be filled with oil to avoid the lack of lubricating oil in the oil-containing bearing body 8 when in use. Timely replenishment of lubricating oil can reduce the friction and wear of the oil-containing bearing body 8, thereby extending the service life of the oil-containing bearing body 8, reducing the frequency and cost of equipment maintenance, and avoiding the unusable cooling fan due to damage to the oil-containing bearing body 8, thereby reducing the failure rate of the equipment.
