Problems solved by technology

However, since the cross-sectional diameter of the bearing 12 is often larger than the cross-sectional diameter of the rotating shaft 14, the cross-sectional diameter of the shaft sleeve 13 is relatively larger than the cross-sectional diameter of the rotating shaft 14. As a result, the internal space of the shaft sleeve 13 is wasted.

Embodiment Construction

[0032] A fan according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same reference symbols.

[0033] In order to improve the performance of the fan and improve the utilization of the existing fan internal space, please refer to Figure 2A , which is a schematic diagram of a fan according to a preferred embodiment of the present invention. The fan 2 of the present invention mainly includes a motor 20 and an impeller 21 , and the motor 20 is used to drive the impeller 21 to rotate. The motor 20 includes two bearings 22 , a shaft sleeve 23 , a rotating shaft 24 , a magnetic element 25 and a plurality of silicon steel sheets 26 . The rotating shaft 24 passes through the shaft sleeve 23 , and the silicon steel sheet group 26 is sleeved on the outside of the shaft sleeve 23 , and the silicon steel sheet group 26 is opposite to the magnetic element 25 .

Abstract

The present invention discloses a fan, which comprises a vane wheel and a motor, and wherein, the motor drives the vane wheel to rotate. The motor comprises a shaft sleeve and a rotary shaft, and the rotary shaft is inserted in the shaft sleeve. The shaft sleeve comprises a tube body and at least one bottom; wherein, the bottom is connected with one end of the tube body; and the inner diameter ofthe tube body is less than the inner diameter of the bottom. Since the tube body and the bottom of the shaft sleeve have different inner diameters, the interior space of the shaft sleeve can be effectively utilized, so that the flexibility of the mechanism design can be enhanced, and furthermore, the efficiency of the fan and the motor can be increased.

Description

technical field [0001] The invention relates to a fan, a motor and a shaft sleeve thereof, in particular to a fan, a motor and a shaft sleeve thereof capable of improving performance. Background technique [0002] As the functions and operating speed of electronic products increase, the heat generated by them also increases relatively. In order to maintain the normal operation of electronic products, fans are often used as heat sinks, and the airflow generated by the fans is used for forced heat dissipation, so that the electronic products The product can be maintained at normal operating temperature. [0003] Please refer to figure 1 As shown, the conventional fan 1 uses a motor 10 to drive the impeller 11 to rotate. In order to make the motor 10 run smoothly, generally a bearing 12 is arranged in the sleeve 13 and covers the rotating shaft 14 so that the rotating shaft 14 can be supported by the bearing 12 to achieve the purpose of running smoothly. [0004] Most of the...
