Preferably, the cross section of described body is equal to or less than the cross section of spacing hole, and the cross section of described root is greater than the cross section of spacing hole.The body of limited post inserts in the spacing hole, body cooperates the spacing hole setting, thereby spacing fixing circuit board, root carries out spacing to circuit board at above-below direction, prevent that circuit board from contacting with fore shell, thereby avoid damaging the components and parts of circuit board, can generate heat during in addition owing to circuit board work, prevent that also the overheated fore shell that causes of components and parts is impaired thereby root limit circuit plate contact fore shell is set.
Preferably, described root is provided with fluting.Save material.
Preferably, described fluting is four and is distributed on around the root.This is the concrete structure that fluting is set, and guarantees the soundness of root under the prerequisite of saving material.
Preferably, described spacing hole is four, lays respectively at four jiaos of circuit board.Arrange like this and make fixation.
Preferably, described fore shell middle part is provided with block piece, and described block piece is positioned at the top of circuit board bearing, and described circuit board is provided be used to the groove of dodging block piece.
Preferably, fan also comprises mesochite, described fore shell comprises an end wall and is arranged on end wall sidewall on every side, described mesochite is socketed on the sidewall, described circuit board is provided with control switch and charging inlet, and corresponding mesochite is respectively equipped with for the first through hole and the second through hole of placing control switch and charging inlet.Mesochite is socketed on the sidewall of fore shell and back cover, thereby makes the more close and firm that connects and fixes between fore shell and the back cover.
The present invention is owing to be fixed on circuit board on the fore shell by hot melt, thereby guarantees that circuit board can not become flexible, and circuit board firmly is fixed on the fore shell.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
The present invention discloses a kind of fan, comprises fore shell and the circuit board that is fixed on the fore shell, and as shown in Figure 1 to Figure 3, described circuit board 1 is fixed on the fore shell 2 by hot melt.The present invention is owing to be fixed on circuit board 1 on the fore shell 2 by hot melt, thereby guarantees that circuit board 1 can not become flexible, and circuit board 1 firmly is fixed on the fore shell 2.
In the present embodiment, what hot melt was fixing is specially, and described fore shell 2 is provided with limited post 21, and corresponding circuit board 1 is provided with spacing hole 11, and described limited post 21 inserts in the spacing hole 11 to be fixed by hot melt; Limited post 21 and spacing hole 11 cooperate, and limited post 21 at first plays spacing fixation to circuit board 1, and then by hot melt is fixing circuit board 1 firmly are fixed on the fore shell 2.Wherein, described limited post 21 comprises a root and a body, and described body and spacing hole 11 cooperate, and the cross section of described body is equal to or less than the cross section of spacing hole 11, and the cross section of described root is greater than the cross section of spacing hole 11.The body of limited post 21 inserts in the spacing hole 11, body cooperates spacing hole 11 to arrange, thereby spacing fixing circuit board 1, root carries out spacing to circuit board 1 at above-below direction, prevent that circuit board 1 from contacting with fore shell 2, thereby avoid damaging the components and parts of circuit board 1, can generate heat during in addition owing to circuit board 1 work, prevent that also the overheated fore shell 2 that causes of components and parts is impaired thereby root limit circuit plate 1 contact fore shell 2 is set.
In the present embodiment, described root is provided with fluting 22, and described fluting 22 is four and is distributed on around the root.This is the concrete structure that fluting 22 is set, and guarantees the soundness of root under the prerequisite of saving material, and certainly, the fluting 22 that other number is set also is feasible.
In the present embodiment, described fore shell 2 middle parts are provided with block piece 23, and described block piece 23 is positioned at the top of circuit board 1 bearing, and described circuit board 1 is provided be used to the groove 12 of dodging block piece 23.Described block piece 23 is trapezoidal plate, because back cover encloses bone arranging to be provided with around the fan assembly, enclose bone one trapezoid-shaped openings that is used for placing wire is set, thereby block piece 23 is just drunk the opening close-fitting, prevents from leaking out.
