The first housing 10 is provided with a first stopper 13. In one embodiment, an outer peripheral wall 121 of the first side 12 is provided with the first stopper 13; wherein the first side 12 can be combined with the periphery of the first base 11 by means such as integral molding or assembly, but is not limited thereto.

[0076] Figure 3 The figure shows an exploded perspective view of a blower fan according to an embodiment of the present invention. Figure 4 A partial side cross-sectional view of a blower fan according to an embodiment of the present invention is shown. Figures 1 to 4 In one embodiment, the second shell base 20 is combined with the first shell base 10, and the second shell base 20 has a second base 21 and a second side portion 22. An air outlet T2 is provided between the second base 21 and the first base 11, and a second limiting member 23 is provided on an outer peripheral wall 221 of the second side portion 22. A channel G is formed between the second limiting member 23 and the first limiting member 13; wherein the second side portion 22 can also be combined with the periphery of the second base 21 by means such as integral molding or assembly, but is not limited to the above. In one embodiment, the first shell base 10 may be provided with a plurality of buckling portions 14, and the second shell base 20 may be provided with a plurality of buckling sheets 24, and the buckling portions 14 are combined with the buckling sheets 24, that is, one buckling portion 14 is correspondingly combined with one buckling sheet 24; thereby, the first shell base 10 and the second shell base 20 can be quickly snap-fitted together using the buckling portions 14 and the buckling sheets 24 to enhance assembly convenience, but the present invention is not limited to the above, and the first shell base 10 and the second shell base 20 may also be fixed by means such as screwing or bonding.

[0077] The impeller 30 is disposed between the first housing 10 and the second housing 20. The impeller 30 may be a blast impeller, which is rotatably coupled to the stator 40. The stator 40 is disposed between the first housing 10 and the second housing 20, and is used to drive the impeller 30 to rotate. The stator 40 has at least one wire 41, and the at least one wire 41 extends through the channel G. Thus, by using the first stopper 13 and the second stopper 23 located around the channel G, the at least one wire 41 can be limited in the channel G, so as to effectively prevent the at least one wire 41 from being loosened or falling off.

[0078] In one embodiment, the second base 21 of the second housing 20 may be provided with a wire outlet 211, and the at least one wire 41 extends to the outside of the second housing 20 through the wire outlet 211; thereby, the at least one wire 41 can be directly wired outside the second housing 20 to avoid the at least one wire 41 occupying the internal space of the blower 1 of the present invention, thereby improving the use margin of the internal space of the blower 1. In addition, the second base 21 of the second housing 20 may be further provided with a wire groove 212, the wire groove 212 is located outside the second housing 20 and connected to the wire outlet 211, the at least one wire 41 is accommodated in the wire groove, and extends through the channel G along the wire groove 212; thereby, the wire groove 212 can be used to store and hide the at least one wire 41, and can also be used to position the at least one wire 41 to provide wiring and fixing functions.

[0079] In one embodiment, the first stopper 13 and the second stopper 23 may jointly form a stopper S around the channel G, the stopper S surrounds the channel G in an axial direction D1 and a radial direction D2, and the stopper S is used to stop and limit the at least one wire 41 in the channel G. Thus, by using the stopper S to surround the channel G in the axial direction D1 and the radial direction D2, even if the at least one wire 41 is improperly pulled by an external force, the stopper S can be used to present a full-circle stopper function to more effectively limit the at least one wire 41 in the channel G, and can completely prevent the at least one wire 41 from being loosened or falling off, thereby ensuring that the blower fan 1 can operate normally, thereby achieving the effect of improving the service life of the blower fan 1 of the present invention.

[0080] Therefore, based on the above structural design, a plurality of embodiments are further listed in detail below to illustrate various structural types of the first limiting member 13, the second limiting member 23 or the stopper S, but are not limited to the embodiments listed below.
