Embodiment

Please refer to Fig. 1, the preferred embodiments of fan of the present invention comprises that framework 10, a hollow and offer a vent hole 12 respectively in two ends is installed in a columniform rotor 30 and the some flabellums 40 that removably is installed in the circumferential surface of this rotor 30 in this framework 10 rotationally.

Please refer to Fig. 2 and Fig. 3, this rotor 30 is offered some draw-in grooves 32 vertically in circumferential surface.Each draw-in groove 32 runs through an end face 31 of this rotor 30 and forms an opening in this end face 31.What each draw-in groove 32 comprised the circumferential surface that runs through this rotor 30 that a accepting groove 320 that the cross section that is interconnected is rounded and a cross section are square wears groove 322.This wears the width of groove 322 less than the diameter of this accepting groove 320.

This end face 31 is respectively equipped with a fixing part 34 and a clamping part 36 in the both sides of each opening.This fixing part 34 comprises a boss 340 that is convexly set in this end face 31 and is convexly set in two lugs 342 at the two ends of this boss 340 respectively.These two lugs, 342 correspondences offer respectively one the perforation 346.This clamping part 36 comprises that one is convexly set in the boss 360 of this end face 31 and is convexly set in this boss 360 and offers a buckle ear 362 perpendicular to the bayonet socket 364 of draw-in groove 32.One interdiction piece 344 comprises stopper part 345 that the opening of a U-shaped makes progress, L shaped rotation section 352 and an engagement portion 354 of being located at these 345 two ends, stopper part and oppositely extending respectively.This rotation section 352 is bent to form a flanging 355 downwards again from outside vertical extension of an end of this stopper part 345.This flanging 355 is convexly equipped with a card post 356 that snaps in the perforation 346 of this two lug 342 rotationally respectively in two ends.This engagement portion 354 is convexly equipped with an operation unit 358 in the side away from this flanging 355.

Each flabellum 40 comprises a fan body 42 and is located at an installing department 43 of these fan body 42 1 sides.This installing department 43 comprises that a portion that wears 44 and that is connected in the long strip of this fan body 42 is connected in the general cylindrical cylinder 46 in this outside that wears portion 44.The diameter of this cylinder 46 wears the width of portion 44 greater than this.

Please refer to Fig. 4, during assembling, the portion that wears 44 of each flabellum 40 and cylinder 46 are worn groove 322 and accepting groove 320 from what the opening of this end face 31 inserted a draw-in groove 32.Rotate these operation units 358 to this fixing part 34, make a end that this interdiction piece 344 is provided with engagement portion 354 to these fixing part 34 resiliently deformables, the end of this engagement portion 354 is snapped in the bayonet socket 364 of this clamping part 36.These stopper part 345 blocks are fixed in this draw-in groove 32 in an end of the cylinder 46 of flabellum 40 with this flabellum 40.

When dismantling a flabellum 40, rotate this operation unit 358 to this fixing part 34, make a end that this interdiction piece 344 is provided with engagement portion 354 to these fixing part 34 resiliently deformables, and make the end of this engagement portion 354 withdraw from this bayonet socket 364, can pull out this flabellum 40 by self-corresponding draw-in groove 32.

In other mode of executions, only need satisfy the width of accepting groove 320 or diameter greater than the width of wearing groove 322 or diameter, draw-in groove 32 can be other shapes, and is as calabash shape, trapezoidal.Therefore, installing department 43 correspondences of flabellum 40 also can be other shapes.
