[0030] In implementation, when the outer frame 108 rotates, the fan blade 104 rotates in the interior of the fan body 1, then the user injects lubricating oil into the inner hole of the oil-bearing bearing body 106, the rotating shaft 107 is inserted into the bearing hole of the oil-bearing bearing body 106, the spherical head face at the bottom end of the oil-bearing bearing body 106 is in contact with the wear-resistant sheet 42, and in this process, the excess air in the outer frame 108 escapes along the side of the oil-bearing bearing body 106. After the fan body 1 is powered on, during the operation of the rotating shaft 107, the lubricating oil climbs up along the surface of the rotating shaft 107 to the central hole of the oil seal ring 431 and the penetration area of the rotating shaft 107. Since the surface of the part in this area is coated with a water-repellent and oil-repellent agent to form a nanometer layer, when the lubricating oil flows to this area and is continuously gathered here to form an oil bead due to the pushing force, the lubricating oil bead is difficult to flow out due to its own tension; under the joint action of the oil seal 433 and the oil break groove 432, the phenomenon of lubricating oil leakage is avoided, and finally flows into the interior of the oil storage groove 112, so as to realize the function of preventing the heat dissipation fan from leaking.

[0031] Working principle: in use, first place the fan body 1 at the specified position of the air purifier, the user places the cover body 110 and the filter screen 114 on the surface of the fan body 1, and then pushes the cover body 110 and the filter screen 114 upwards, so that the installation sliding block 22 slides in the installation sliding groove 23, and the cover body 110 is guided under the joint action of the installation sliding block 22 and the installation sliding groove 23.

Under the action of the filter screen 114, the dust and other impurities in the air are blocked and screened, so as to avoid the dust and impurities from entering the interior of the fan body 1, so as to realize the function of the heat dissipation fan that the cover body 110 and the filter screen 114 are conveniently assembled, so that the user can conveniently assemble the cover body 110 and the filter screen 114 on the surface of the fan body 1 when using the heat dissipation fan, and the heat dissipation fan has better dustproof effect on the interior of the fan body 1 when in use.

[0032] Subsequently, the hot air inside the air purifier enters the inside of the fan body 1 through the air inlet hole 109, and under the action of the rotating shaft 107, the outer frame 108 rotates in the inside of the fan body 1.

In this process, the excess air in the outer frame 108 escapes along the side of the oil-containing bearing body 106. After the fan body 1 is powered on, the lubricating oil climbs up along the surface of the rotating shaft 107 during the operation of the rotating shaft 107, and the center hole of the oil seal ring 431 and the penetrating area of the rotating shaft 107 are formed. Because the surface of the part is coated with a water and oil repellent agent to form a nanometer layer, the lubricating oil continuously accumulates in this place to form an oil bead when it flows to this area under the action of the thrust force. The lubricating oil bead is difficult to flow out due to its own tension; under the joint action of the oil seal 433 and the oil break groove 432, the phenomenon of lubricating oil leakage is avoided, and finally flows into the inside of the oil storage groove 112. In this way, the lubricating oil circulates in the inside of the oil-containing bearing body 106 and the rotating shaft 107 to achieve the function of preventing the leakage of the cooling fan, so that the lubricating oil circulates in the inside of the oil-containing bearing body 106 during the use of the cooling fan, and the phenomenon of lubricating oil leakage is eliminated, and the noise is reduced.

Under the action of the motor body 331, the rotating column 332 rotates in the inside of the containing groove 31. When the rotating column 332 rotates, the rotating column 332 drives the rotating toothed disc 32 to rotate in the inside of the containing groove 31. Under the meshing action of the rotating toothed disc 32 and the half toothed disc 333, the half toothed disc 333 rotates in the inside of the containing groove 31. Under the action of the half toothed disc 333, the angle of the fan body 1 is adjusted, so that the fan body 1 has higher practicality, to realize the function of adjusting the angle of the cooling fan, so that the fan body 1 can be adjusted to the required angle for use according to the needs during the use of the cooling fan, so that the cooling fan is more practical during use. Finally, the use of the cooling fan is completed.
