Abstract
A fan includes a frame, a rotor rotatably mounted in the frame,
and a vane. The rotor includes a slot defined in the circumference
of the rotor. The slot extends through an end surface of the rotor.
The vane forms an installing portion to be inserted into the slot
through the end surface. A first base and a second base are formed
on the end surface at opposite sides of the slot. A blocking member
is pivotably mounted to the first base with a first end, and is
detachably engaged with the second base with a second end, to fix
the installing portion in the slot.

Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a fan whose vanes are
replaceable.
[0003] 2. Description of Related Art
[0004] Vanes of fans are generally integrally formed on the
circumference of the fans. As a result, if different shaped fans or
more vanes are needed, new fans will be required, which is
costly.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] Many aspects of the present embodiments can be better
understood with reference to the following drawings. The components
in the drawings are not necessarily drawn to scale, the emphasis
instead being placed upon clearly illustrating the principles of
the present embodiments. Moreover, in the drawings, all the views
are schematic, and like reference numerals designate corresponding
parts throughout the several views.
[0006] FIG. 1 is an exploded, isometric view of an exemplary
embodiment of a fan.
[0007] FIG. 2 is a partially assembled, isometric view of FIG.
1.
[0008] FIG. 3 is an enlarged view of the circled portion III of
FIG. 2.
[0009] FIG. 4 is an enlarged view of the circled portion IV of FIG.

DETAILED DESCRIPTION
[0010] The disclosure, including the accompanying drawings, is
illustrated by way of example and not by way of limitation. It
should be noted that references to "an" or "one" embodiment in this
disclosure are not necessarily to the same embodiment, and such
references mean at least one.
[0011] Referring to FIG. 1, an exemplary embodiment of a fan
includes a hollow and substantially rectangular frame 10, a
columnar rotor 30 rotatably mounted in the frame 10, and a
plurality of vanes 40 detachably mounted on the circumference of
the rotor 30. The frame 10 defines a vent 12 in each of the
opposite ends, to expose the rotor 30 and the vanes 40.
[0012] Referring to FIGS. 2 and 3, the rotor 30 defines a plurality
of slots 32 in the circumference. The slots 32 extend along a
direction parallel to the rotating axis of the rotor. Each slot 32
extends through an end surface 31 of the rotor 30. Each slot 32
includes a first slot 320 having a round cross section and
extending through the end surface 31, and a rectangular second slot
322 communicating with the first slot 320 and extending through the
circumference of the rotor 30. The width of the second slot 322 is
less than the diameter of the first slot 320.
[0013] A first base 34 and a second base 36 are formed on the end
surface 31, at the opposite sides of each slot 32. The first base
34 includes a block 340 protruding from the end surface 31, and two
tabs 342 protruding from opposite ends of the block 340. Each tab
342 defines a pivot hole 346. The second base 36 includes a block
360 protruding from the end surface 31, and an ear 362 protruding
from the block 360 and defining a fixing hole 364 extending through
opposite sides of the ear 362. A blocking member 344 is pivotably
mounted to the first base 34. The blocking member 344 includes a
U-shaped main portion 345 with an opening, and a pivoting portion
352 and a plate 354 substantially perpendicularly extending out
from opposite ends of the main portion 345. The pivoting portion
352 substantially perpendicularly extends out from the end of the
main portion 345 and extends down away from the opening of the main
portion 345 to form a short flange 355. Two pins 356 extend out
from opposite ends of the flange 355, to be pivotably engaged in
the corresponding pivot holes 346, to pivotably mount the blocking
member 344 to the first base 34. An operation piece 358
substantially perpendicularly extends from the plate 354, away from
the flange 355.
[0014] Each vane 40 includes a main body 42 and an installing
portion 43 connected to a side of the main body 42. The installing
portion 43 includes a pole 46 having a round cross-section, and a
rectangular extension portion longitudinally connected between the
pole 46 and the main body 42. The width of the extension portion 44
is less than the diameter of the pole 46.
[0015] Referring to FIG. 4, in assembly of each vane 40, the
installing portion 43 is inserted into a corresponding slot 32
through the end surface 31. Thereby, the pole 46 and the extension
portion 44 are respectively received in the first and second slots
320 and 322.
[0016] The corresponding blocking member 344 is pivoted toward the
second base 36, with the opening of the main portion 345 facing
away from the end surface 31. The operation portion 358 is operated
toward the first base 34, to slightly deform the main portion 345
toward the first base 34. A distal end of the plate 354 is aligned
with the corresponding fixing hole 364. After the operation portion
358 is released, the main portion 345 is self-restored to allow the
distal end of the plate 354 engage into the fixing hole 364. A
bottom wall of the center portion 345 opposite to the opening is
abutted against an end of the pole 46 at the end surface 31, to fix
the vane 40 in the slot 32.
[0017] In uninstalling one of the vanes 40, the operation portion
358 is operated toward the first base 34, to disengage the distal
end of the plate 354 from the fixing hole 364. Therefore, the vane
40 is ready for being taken out of the corresponding slot 32.
[0018] In another embodiment, each slot 32 can be any shape as long
as the width or diameter of the second slot 322 is less than the
width or the diameter of the first slot 320.
[0019] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
various changes may be made thereto without departing from the
spirit and scope of the description or sacrificing all of their
material advantages, the examples hereinbefore described merely
being exemplary embodiments.
