Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The invention relates to a ceiling fan structure and, in
particular, to a ceiling fan structure whose blade supports are
installed on a decorative cover that is connected to the motor
thereof.
[0003] 2. Related Art
[0004] A conventional ceiling fan structure is illustrated in FIG.
3. It has a motor 51. The blades 52 thereof are installed on
supports 53, which are then installed on the motor 51. As the motor
51 rotates, the supports 53 are driven to rotate the blades 52. Due
to the restriction of suitable position on the motor 51 in such a
structure as well as the limited space, the supports 53 and the
blades 52 can only be mounted at specific places. Therefore, the
ceiling fan structure has very limited variations and
decorations.
[0005] It is then the main theme of the invention to solve the
above-mentioned problems.
SUMMARY OF THE INVENTION
[0006] An objective of the invention is to provide a ceiling fan
structure whose blade supports are installed on a decorative cover
that is connected to a motor. The motor rotates the decorative
cover, which then drives the blade supports to rotate. Therefore,
the blade supports can be installed at any arbitrary places on the
decorative cover according to one's need, rendering high
versatility of the ceiling fan.
[0007] To achieve the above-mentioned objective, the disclosed
ceiling fan structure includes a motor, a decorative cover, and
several blade components. The decorative cover covers on the outer
side of the motor, and is installed on the motor. Each of the blade
components includes a support and a blade. Each blade is installed
on a corresponding support. Each support is installed on the
decorative cover. As the motor drives the decorative cover to
rotate, thereby rotating the blade components.
[0008] The bottom of the motor is mounted with a connecting base
that has a lamp. The bottom of the decorative cover has an opening
for the connecting base to go through.
[0009] The bottom of the decorative cover has several fixing holes.
The top of each support has a fixing part. Each support is mounted
under the decorative cover, with a fixing element going downward
through the corresponding fixing hole of the decorative cover and
fixing onto the corresponding fixing part of the support. The
supports are thus integrated to the decorative cover.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] These and other features, aspects and advantages of the
invention will become apparent by reference to the following
description and accompanying drawings which are given by way of
illustration only, and thus are not limitative of the invention,
and wherein:
[0011] FIG. 1 is an exploded view of the invention;
[0012] FIG. 2 is a partial cross-sectional view of the invention
after assembly; and
[0013] FIG. 3 is an exploded view of a conventional ceiling fan
structure.
DETAILED DESCRIPTION OF THE INVENTION
[0014] The present invention will be apparent from the following
detailed description, which proceeds with reference to the
accompanying drawings, wherein the same references relate to the
same elements.
[0015] Please refer to FIGS. 1 and 2 for the ceiling fan structure
according to the invention. The disclosed ceiling fan structure
includes a motor 1, a decorative cover 2, and several blade
components 3 (only one of which is shown). The motor 1 is an
external rotor motor. That is, the rotor surrounds a stator on the
axis and rotates with respect to the axis. The decorative cover 2
encloses the motor 1 from the outer side thereof and is mounted on
the rotor of the motor 1. In this embodiment, the decorative cover
2 is locked onto the rotor of the motor 1 using fixing screws 21.
As the motor 1 rotates, the decorative cover 2 is driven to rotate
as well.
[0016] Each of the blade components 3 includes a support 31 and a
blade 32. Each of the blades 32 is installed on a corresponding
support 31. Each support is installed on the decorative cover 2. In
this embodiment, the bottom of the decorative cover 2 has several
fixing holes 22. The top of each support 31 has a fixing part 311.
Each support 31 is installed under the decorative cover 2. A fixing
element 33 going downward through the corresponding fixing hole 22
of the decorative cover 2 and fixing onto the corresponding fixing
part 311 of the support 31, thereby integrating the supports 31 and
the decorative cover 2 together. When the motor 1 rotates the
decorative cover 2, the blade components 3 are driven to rotate as
well.
[0017] As described above, the invention has the advantage that the
rotation of the blade components 3 is achieved via the decorative
cover 2. Therefore, each of the blade components 3 can be installed
on an arbitrary position on the decorative cover 2 and still
achieve the desired rotation effect. Furthermore, the decorative
cover 2 can be designed to have creative, characteristic style and
shape. Each of the blade components 3 can be installed at an
appropriate position on the decorative cover 2 under the
consideration of practical and beauty purposes. Therefore, there
are more places for the blade components 3 to install. The ceiling
fan thus has higher versatility in shape and becomes
decorative.
[0018] Besides, the bottom of the motor 1 is provided with a
connecting base 11 for the connection of a lamp 4. The bottom of
the decorative cover 2 has a corresponding opening 23 for the
connecting base 11 to go through. In this case, the disclosed
ceiling fan has the functions of both illumination and
decoration.
[0019] Although the invention has been described with reference to
specific embodiments, this description is not meant to be construed
in a limiting sense. Various modifications of the disclosed
embodiments, as well as alternative embodiments, will be apparent
to people skilled in the art. Therefore, it is contemplated that
the appended claims will cover all modifications that fall within
the true scope of the invention.
