Description
FIELD OF THE INVENTION
[0001] The present invention relates to a fast detachable automatic
cleaning device, and particularly to an automatic cleaning device
having a simplified structure and reinforced assembly strength.
BACKGROUND OF THE INVENTION
[0002] Common means for cleaning the floor generally involve tools
such as brooms and mops for the cleaning operation. However, with
the development of modern technologies, in addition to automatic
cleaning tools such as vacuum cleaners and floor cleaning robots in
the field of household appliances, there are also large-scale
automatic cleaning devices developed for significantly reducing the
time needed for cleaning operations. More specifically, for
example, the Taiwan Patent No. 1507165 discloses a self-propelled
cleaning device including a cleaning member. The cleaning member
includes a fixed portion, an extension portion and a cleaning
portion. The extension portion extends along an edge of the fixed
portion. The cleaning portion includes a plurality of cantilevers
radially extending outwards from the extension portion, and a
plurality of scraping portions respectively disposed at the
cantilevers. Further, when applying the self-propelled cleaning
device, the fixed portion is driven by the cleaning member to
rotate to further cause the fixed portion to drive the cleaning
portion to rotate through the extension portion. As such, while
moving in a self-propelled manner, the self-propelled cleaning
device drives the scraping portions to rotate through the cleaning
portion to perform a cleaning operation.
[0003] After using the above self-propelled cleaning device for a
period of time, the cleaning member may be contaminated by dirt or
damaged, and needs to be replaced or cleaned. Thus, a detachable
structure is generally designed between the cleaning member and the
automatic cleaning device. For example, the Taiwan Patent No.
1462716 discloses a fast detachable cleaning device including a
driving mechanism and a cleaning disk mechanism. The driving
mechanism includes a transmission shaft and an elastic member
covering the transmission shaft. The cleaning disk mechanism
includes a turntable, a bearing axis disposed at the turntable, and
a plurality of cleaning thread strips radially connected to the
turntable. The elastic member includes a fastening protrusion
extended, bent and formed along the surface of the transmission
shaft. The bearing axis includes a fastening recess corresponding
to the fastening protrusion. Accordingly, the fast detachable
cleaning device may be promptly assembled and disassembled through
fastening and detaching the fastening recess and the fastening
protrusion.
[0004] However, it is found from the technical contents of the
Taiwan Patent No. 1462716 that, an issue of complicated structure
of the driving mechanism is caused as the transmission shaft and
the elastic member are separate components. Further, the fastening
protrusion is disposed at the elastic member. Thus, when the
transmission shaft and the bearing axis undergo multiple assembly
processes, the elastic member is prone to elasticity fatigue in a
way that the fastening protrusion may fail to become steadily
fastened with the fastening recess, hence resulting in an insecure
assembly of the transmission shaft and the bearing axis.
SUMMARY OF THE INVENTION
[0005] It is a primary object of the present invention to solve
issues of a complicated structure and insufficient assembly
strength of conventional solutions.
[0006] To achieve the above object, the present invention provides
a fast detachable automatic cleaning device including a driving
assembly and a cleaning assembly. The driving assembly includes a
transmission shaft that performs a rotation process when activated,
and at least one protrusion block disposed at a periphery of the
transmission shaft and being a formed integral with the
transmission shaft. The cleaning assembly is connected to the
transmission shaft and rotates along with the rotation process. The
cleaning assembly includes a seat, a bearing sleeve connected to
the seat, and a cleaning portion surrounding the seat. The bearing
sleeve includes an assembly space, at least one track in
communication with the assembly space, and at least one fixing hole
in communication with the assembly space. The cleaning assembly has
a first assembly state in which the protrusion block is placed in
the assembly space along the track, and a second assembly state in
which the seat is rotated to cause the bearing sleeve to rotate
relative to the transmission shaft to further cause the protrusion
block to be fastened in the fixing hole.
[0007] In one embodiment, the shape of the protrusion block
corresponds to the shape of the fixing hole. Further, the surface
of the protrusion includes at least one first guiding plane, and
the bearing sleeve is provided with a second guiding plane at each
of two opposite sides of at the track. Further, each of the first
guiding plane and the second guiding plane is a slanted plane or an
arched plane. More specifically, the track penetrates the bearing
sleeve to allow the assembly space to be in communication with the
exterior. More specifically, the driving assembly includes a
plurality of protrusion blocks that are evenly spaced and arranged
at an outer periphery of the transmission shaft, the bearing sleeve
includes a plurality of tracks and a plurality of fixing holes, and
the tracks and the fixing holes are evenly spaced and sequentially
arranged at an outer periphery of the bearing sleeve.
[0008] In one embodiment, the cleaning portion includes a plurality
of arms extending away from the seat, and a plurality of cleaning
strips respectively disposed correspondingly to the arms.
[0009] In one embodiment, the transmission shaft includes a channel
disposed in the transmission shaft, and two through holes disposed
at the transmission shaft near two sides of the protrusion block
and in communication with the channel.
[0010] Through the above embodiments, the present invention
provides following features compared to conventional solutions. In
the present invention, the track of the bearing sleeve allows the
protrusion block of the transmission shaft to be guided and placed
in, and the driving assembly is a formed integral including the
transmission shaft and the protrusion block to further provide a
simplified structure. Therefore, the protrusion block is allowed to
be securely fastened in the fixing hole to enhance the assembly
strength of the transmission shaft and the bearing sleeve, thereby
solving the issues of a complicated structure and insufficient
assembly strength of conventional solutions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Details and technical contents of the present invention are
given with the accompanying drawings below.
[0018] Referring to FIG. 1, the present invention provides a fast
detachable automatic cleaning device (e.g., the dotted part shown
in FIG. 1), which performs a cleaning operation in a self-propelled
manner. The fast detachable automatic cleaning device includes a
driving assembly 1 and a cleaning assembly 2, as shown in FIG. 2
and FIG. 3. The driving assembly 1 includes a transmission shaft 11
and at least one protrusion block 12. The protrusion block 12 is
disposed at a periphery of the transmission shaft 11, and the
transmission shaft 11 and the protrusion block 12 are a formed
integral. The cleaning assembly 2 includes a seat 21, a bearing
sleeve 22 and a cleaning portion 23. The bearing sleeve 22 is
connected to the seat 21. The cleaning portion 23 surrounds the
seat 21. In one embodiment, the seat 21 is appears as a disk, and
the bearing sleeve 22 is connected to an axial position of the seat
21. More specifically, the bearing sleeve 22 includes an assembly
space 221, at least one track 222 and at least one fixing hole 223.
The assembly space 221 is formed at an inner side of the bearing
sleeve 22, the track 222 and the fixing hole 223 are at disposed at
the bearing sleeve 22, and the track 222 and the fixing hole 223
are both in communication to the interior of the assembly space
221. More specifically, the width of the track 222 corresponds to
the width of the protrusion block 12, and the shape of the
protrusion block 12 corresponds to the shape of the fixing hole
223. In one embodiment, the track 222 penetrates the bearing sleeve
22 to allow the assembly space 221 to be in communication with the
exterior. Further, in another embodiment, the track 222 may be a
groove (not shown) facing the assembly space 221. The cleaning
portion 23 includes a plurality of arms 231 and a plurality of
cleaning strips 232. The arms 231 radially extend away from the
seat 21 from the periphery of the seat 21, and the cleaning strips
232 are respectively disposed correspondingly to the arms 231. More
specifically, the cleaning strips 232 may be formed by any desired
cleaning components such as bristles, cloth strips or scrapers
according to application requirements (e.g., sweeping or mopping
the floor) of the fast detachable automatic cleaning device.
[0019] Referring to FIG. 3, FIG. 4A and FIG. 4B, when the fast
detachable automatic cleaning device is to be assembled, the
cleaning assembly 2 sequentially enters a first assembly state and
a second assembly state. More specifically, in the first assembly
state, the bearing sleeve 22 sleeves accommodates around the
transmission shaft 11, and the protrusion block 12 is placed into
the assembly space 221 along the track 222. Next, in the second
assembly state, the bearing sleeve 22 performs a rotation process
to cause the protrusion block 12 to rotate closely to the inner
wall of the bearing sleeve 22. When the bearing sleeve 22 is
rotated by an angle in a way that the fixing hole 223 is aligned
with the protrusion block 12, the protrusion block 12 is fastened
in the fixing hole 223. Thus, the fast detachable automatic
cleaning device completes the assembly process of the driving
assembly 1 and the cleaning assembly 2 through the foregoing
operations, so that the fast detachable automatic cleaning device,
while moving in a self-propelled manner, is capable of driving the
transmission shaft 11 to rotate through the driving assembly 1 to
allow the cleaning strips 232 perform cleaning through the rotation
operation.
[0020] To disassemble the fast detachable automatic cleaning
device, the bearing sleeve 22 may dislocate the protrusion block 12
from the fixing hole 223 through the rotation process, such that
the track 222 moves to and becomes aligned with the protrusion
block 12 along with the rotation process. Thus, the protrusion
block 12 is allowed to move away from the bearing sleeve 22 along
the track 222 to release the engagement between the driving
assembly 1 and the cleaning assembly 2, hence completing the
disassembly process of the fast detachable automatic cleaning
device.
[0021] Accordingly, it is clearly understood from the foregoing
technical contents that, when the assembly or disassembly process
of the fast detachable automatic cleaning device of the present
invention is performed, the track 222 of the bearing sleeve 22
allows the protrusion block 12 of the transmission shaft 11 to be
guided and placed in, and the driving assembly 1 is a formed
integral including the transmission shaft 11 and the protrusion
block 12 to further provide a simplified structure. Therefore, the
protrusion block 12 is allowed to be securely fastened in the
fixing hole 223 to enhance the assembly strength of the
transmission shaft 11 and the bearing sleeve 22, thereby solving
the issues of a complicated structure and insufficient assembly
strength of conventional solutions.
[0022] To provide a more smooth assembly or disassembly process of
the fast detachable automatic cleaning device of the present
invention, in one embodiment, the surface of the protrusion block
12 includes at least one first guiding plane 121, as shown in FIG.
4A and FIG. 4B. Thus, when putting the embodiment to practice, the
bearing sleeve 22 performing the rotation process allows the
protrusion block 12 to be smoothly guided to the inner wall of the
bearing sleeve 22 through the first guiding plane 121, so that the
process of the protrusion block 12 moving to the fixing hole 223
through the track 222 is made more smooth to thereby enhancing the
smoothness of the assembly process of the fast detachable automatic
cleaning device. The bearing sleeve 22 may further include a second
guiding plane 224 at each of two opposite sides of the track 222,
as shown in FIG. 4A and FIG. 4B. Thus, with the guiding
relationship of the first guiding plane 121 and the second guiding
plane 224, the protrusion block 12 may be smoothly guided and
extruded at the inner wall of the bearing sleeve 22 to further
enhance the smoothness of the assembly process of the fast
detachable automatic cleaning device. Each of the first guiding
plane 121 and the second guiding plane 224 may be a slanted plane
or an arched plane.
[0023] To further enhance the smoothness of the assembly or
disassembly process of the fast detachable automatic cleaning
device, in one embodiment, the transmission shaft 11 further
includes a channel 111 disposed in the transmission shaft 11, and
two through holes 112 disposed at the transmission shaft 11 near
two sides of the protrusion block 12 and in communication with the
channel 111, as shown in FIG. 5. Further, when putting this
embodiment to practice, the transmission shaft 11 may provide the
protrusion block 12 with elasticity for extrusion and movement
through the channel 111 and the two through holes 112 that are in
communication, hence allowing the protrusion block 12 to move
smoothly between the track 222 and the fixing hole 223.
[0024] More specifically, in the foregoing embodiments of the
present invention, implementation of the driving assembly 1
including at least one protrusion block 12 and the cleaning
assembly 2 including at least one track 222 and at least one fixing
hole 223 is described. However, in practice, the protrusion block
12, the track 222 and the fixing hole 223 may be implemented in
plural numbers. The protrusion blocks 12 may be evenly spaced and
arranged at an outer periphery of the transmission shaft 11, and
the tracks 222 and the fixing holes 223 may be evenly spaced and
sequentially arranged at an outer periphery of the bearing sleeve
22. Thus, according to the required assembly strength between the
transmission shaft 11 and the bearing sleeve 22, the numbers of the
protrusion blocks 12, the tracks 222 and the fixing holes 223 of
the fast detachable automatic cleaning device may be increased or
decreased.
