Abstract

The invention discloses a mini fan, which comprises a substrate, a stator, a rotor, a sealing magnetic sheet and a permanent magnet. The stator is arranged in the substrate; the rotor is provided with an axial seat of which the peripheral face is provided with a plurality of blades; the sealing magnetic sheet is provided with a first combining surface and a second combining surface; the first combining surface of the sealing magnetic sheet combines with hemlines of each blade; and the permanent magnet combines with the second combining surface of the sealing magnetic sheet and is opposite to the stator. Thus, the overall volume of the mini fan can be reduced effectively without reducing the amount of air output.

Description

technical field [0001] The invention relates to a fan, in particular to a blower type miniature fan with a side air outlet function. Background technique [0002] Please refer to figure 1 , 2 As shown, the conventional blower fan 9 includes a base 91 , a stator 92 , a rotor 93 and a cover 94 . The base 91 is a hollow shell, and the side and the top of the base 91 respectively have a side air outlet 911 and an opening 912; the stator 92 is combined in the base 91; the rotor 93 includes a hub 931, a metal ring 932 and a permanent magnet 933, a spoke plate 934 and several blades 935, the hub 931 is rotatably combined in the base 91, the metal ring 932 is combined on the inner peripheral surface of the hub 931, The permanent magnet 933 is combined with the inner peripheral surface of the metal ring 932, so that the metal ring 932 can be interposed between the hub 931 and the permanent magnet 933 to provide a magnetic effect, and the web 934 is separated from the hub The oute...
