[0032] See figure 1 , the fan 100 provided by the first embodiment of the present invention includes a rotor part 130 . The rotor part 130 includes a hub 131 and a plurality of blades 133 .

[0033] The hub 131 includes a top plate 1311 and a side wall 1312 . The side wall 1312 is annular, such as a rotating cylinder, and the top plate 1311 is located at the center of the side wall 1312 and connects the periphery of the side wall 1312 . There is an included angle between the top plate 1311 and the side wall 1312, preferably 90 degrees, and of course it can be greater than 90 degrees. The hub 131 is generally cylindrical or conical.

[0034] The fan blade 133 is disposed on the outer surface 1313 of the side wall 1312 and extends substantially radially from the center of the hub 131 . The number of fan blades 133 is not limited, and can be evenly distributed on the outer surface 1313 of the side wall 1312 .

[0035] In this embodiment, at least one through hole 134 is dispo...

[0040] See figure 2 The fan 200 provided by the second embodiment of the present invention includes a fan frame 110 , a stator portion 120 disposed on the fan frame 110 , and a rotor portion 130 rotatably engaged with the stator portion 120 . The fan 200 in this example adopts a drive mode in which the magnetic member 135 cooperates with the coil.

[0041] The fan frame 110 includes a bracket 111, a first outer frame 112, a second outer frame 115, a side frame 113 and a beam 114, please refer to image 3 with Figure 4 . Wherein, the bracket 111 is connected with the stator part 120, and the bracket 111 may specifically be a disk-shaped bracket.

[0042] See image 3 , the first outer frame 112 is specifically a cube-shaped frame with a hole, the hole can be a circular hole, and the center of the hole coincides with the center of the bracket 111, and the outer edge of the bracket 111 and the inner side of the first outer frame 112 Fixedly connected by a plurality of beam...

[0056] See Figure 9 , Figure 9 shows a schematic structural diagram of a fan 300 provided by the third embodiment of the present invention, and figure 2 Compared to the fan 200 shown, the differences are:

[0057] Figure 9 The shown fan 300 is not provided with a shaft sleeve, but a groove 124 is opened at the center of the bracket 111 , and a fixing clip 125 is arranged inside the groove 124 . An end of the rotating shaft 132 away from the top plate 1311 protrudes into the groove 124 and rotatably cooperates with the fixing clip 125 . The stator coil 121 is connected to the PCB 123 through a fixing block 126 .

[0058] The working principle of the fan provided by the second embodiment and the third embodiment of the present invention is as follows:

[0059] When the control circuit of the PCB board 123 supplies power to the stator coil 121 , the stator coil 121 is magnetic, and the magnetic stator coil 121 interacts with the magnetic member 135 to make the magnetic m...

Abstract

The fan and electronic equipment provided by the embodiments of the present invention include a rotor part, and the rotor part includes fan blades and a hub. The hub includes a side wall for fixing the fan blade and a top plate connected to the side wall, the top plate is provided with at least one through hole, and the inner surface of the side wall is provided with a wind guiding structure. When the fan rotates and the airflow passes through the fan with the rotation of the blades, part of the airflow will pass through the through hole of the top plate and flow out from the assembly gap between the stator part and the rotor part through the gap between the stator part and the rotor part. The path into the inside of the fan is opposite, and the air guide structure on the inner surface of the side wall is more conducive to the flow of air in the gap between the stator part and the rotor part, thereby avoiding the deposition of dust on the part where the stator part and the rotor part rotate and cooperate, which is beneficial to Improve the service life of the fan.

Description

technical field [0001] The invention relates to the field of components, in particular to a fan and electronic equipment. Background technique [0002] The fan is a device that people often need to use in production and life. The fan can dissipate heat and cool down the electronic components by rotating, thereby prolonging the service life of the electronic components. However, in the process of use, dust often enters the rotation matching parts of the stator and the rotor of the fan, which brings wear to the rotation matching parts of the stator and the rotor, and greatly reduces the service life of the fan. [0003] In the prior art, a staggered structure is provided in the assembly gap between the stator and the rotor of the fan to prevent dust from entering. The assembly gap is set to prevent the contact between the rotor and the stator, which can ensure the normal rotation of the rotor. However, setting the staggered structure in the assembly gap needs to occupy a lar...
