Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present invention relates to dusting sheets, and in
particular to a 3D dusting sheet, which includes a multi-layer
structure and a surface thereof is three-dimensional, and a method
for manufacturing the same is also included in the present
invention.
[0003] 2. Prior Art
[0004] FIG. 1 shows a utility model patent, TW 592118, entitled
"Improved 3D Dusting Paper". As shown in the figure, the utility
model patent is basically characterized in that a storage layer 911
is respectively disposed on the two sides of the middle layer 912
of the dusting paper having multiple layers, wherein a plurality of
storage spaces 99 are carved out in the storage layer 911 for
storing dirt or dust in the storage spaces 99. A plurality of fins
98 extending in different directions are disposed on the storage
spaces 9 9. The fins 98 are further adhered to the storage layer
911 with high frequency bounding to make the fins 98 and the
storage spaces 99 cooperate with each other. An adhesion portion is
respectively disposed on the two sides of the storage layer 911 for
adhering the main body 91 of the dusting paper onto the main body
92 of a mop (see FIG. 2), and a plurality of dust or dirt in the
storage spaces 99, since a large amount of dust or dirt tends to
gather on the perimeter of the dusting paper and move along with
the perimeter of the dusting paper while the dusting paper are in
contact with the objects to be cleaned (e.g. the floor), only a few
dirt may move to the center of the dusting paper, which results in
failure to completely exert the dusting effect of the dusting paper
or cloth.
SUMMARY OF THE INVENTION
[0005] In view of the defects of the prior art, the present
invention provides a 3D dusting sheet and a method for
manufacturing the same, wherein the 3D dusting sheet comprises a
structure in which one or more linings are disposed between the
base sheet and the electrostatic dusting sheet, such that the
surface of the 3D dusting sheet becomes three-dimensional, whereby
a large amount of dirt is gathered in one or more three-dimensional
spaces. Since the surface of the 3D dusting sheet is
three-dimensional, the friction may be more concentrated during
cleaning, and the effect of scraping and collecting the dust or
dirt at the same time may be achieved. Regarding the method for
manufacturing the same, the 3D dusting sheet is formed by partially
re-incorporating the leftovers generated by trimming the fabrics
during the process in-between the base sheet and the electrostatic
dusting sheet through guiding means. In such a manner, a 3D dusting
sheet with excellent capability can be manufactured
economically.

DETAILED DESCRIPTION
[0014] In order to achieve the aforesaid objectives of the
invention, a preferred embodiment of the present invention is
provided herein. Please refer to FIG. 4A, which is a top view of
the dusting sheet according to the present invention, wherein the
chain line indicated by the two arrows is the reference line along
which the cross-sectional view of FIG. 4B is taken. As shown in
FIGS. 4A and 4B, the main body (1) of the dusting sheet comprises a
base sheet (24) and an electrostatic dusting sheet (21), and a
plurality of linings (22) are disposed between the base sheet (24)
and the electrostatic dusting sheet (21) for bulging partially the
main body (1) of the dusting sheet, so as to form the solid layers
as shown in the figure. The electrostatic dusting sheet (21)
including the multi-layer structure is carved by cutter wheel to
form a plurality of triangular fins (7), and a plurality of storage
spaces (9) are further disposed under the fins (7) correspondingly.
The fins (7) help shove the dust or dirt into the storage spaces
(9) for storing the dust or dirt, and in cooperation with the main
body (1) of the dusting sheet partially stuffed with the linings
(22), a dusting sheet comprising multiple inter-layer profiles can
be formed thereby to achieve excellent dusting effect.
[0015] The linings (22) used in the embodiments of the present
invention are leftover cloth straps generated in the manufacturing
process of the electrostatic dusting sheet (21). As shown in FIGS.
4A and 4B, since the electrostatic dusting sheet (21) is trimmed to
be narrower than the base sheet (24), the leftovers of the margin
of the electrostatic dusting sheet (21) may be used as the basic
material of the linings (22), and the width of the linings (22) may
be adjusted according to the desired size of the leftovers. Please
refer to FIG. 5, which shows the first embodiment of the present
invention, wherein each of the two linings (22) is disposed between
the base sheet (24) and the electrostatic dusting sheet (21), and
the bold lines in the figure indicates the positions where the two
linings (22) are installed. As a result, the main body (1) of the
dusting sheet according to the first embodiment may partially bulge
at the portions stuffed with the linings (22), thereby forming two
elongate bulgy portions on the main body (1) of the dusting sheet,
as shown in the cross-sectional view of FIG. 4B. When the 3D
dusting sheet of the present invention is applied, the elongate gap
between the two bulgy portions and the outer sides of the two bulgy
portions may store a large amount of dust or dirt, such that by
this three-dimensional design, the friction may be concentrated on
the bulgy portions of the 3D dusting sheet during cleaning, and the
effect of scraping and collecting the dust or dirt at the same time
may be achieved.
[0016] Next, please refer to FIG. 6, which shows the second
embodiment of the present invention. As shown by the bold lines in
the figure, the linings (22) overlap each other by halves.
Therefore, due to the thickness of the linings (22), the overlapped
middle portion of the linings (22) is higher; that is, the middle
portion of main body (1) of the dusting sheet bulges to be higher,
and the height gradually degrades toward the lateral sides.
According to such an arrangement of the linings (22), the friction
may be mainly concentrated on the middle portion of the main body
(1) of the dusting sheet, and the effect of scraping dust or dirt
may be achieved. Particularly to a wet surface to be cleaned, the
3D dusting sheet according to this embodiment may function as a
scraper to scrape off the dirt and collect the dirt on the two
lateral sides of the middle bulgy portion.
[0017] Please refer to FIG. 7, which shows the third embodiment of
the present invention. As shown by the bold lines in the figure,
the linings are disposed substantially in an S-shape for increasing
the friction on the main body (1) of the dusting sheet. Since the
linings (22) are disposed substantially in the S-shape on the main
body (1) of the dusting sheet, the user may find the friction
applied onto the entire main body (1) of the dusting sheet
uniformly during manipulation and experience better feel of
handling while achieving the effect of scraping and collecting the
dust or dirt at the same time.
[0018] Next, please refer to FIG. 8, which is a schematic view of
the 3D dusting sheet of the present invention collecting dust in
practice. As shown in the figure, the portion stuffed with the
linings (22) in the middle is bulged. If the 3D dusting sheet
sweeps from the left to the right, a large amount of dust (23) can
be collected on the right side of the 3D dusting sheet, and the
particles with irregular mass and shape are collected between the
fins (7) and the storage spaces (9), as shown in the figure. The
electrostatic dusting sheet (21) used in the present invention may
be made of ultra-electrostatic micro-porous fiber, and the base
sheet can be made of chemical fiber or natural fiber, in particular
a non-woven fabric formed of fusible fiber. The linings (22) may be
made with the leftovers generated in the manufacturing process of
the 3D dusting sheet or another material from another source.
[0019] The process of manufacturing the 3D dusting sheet of the
present invention includes: [0020] preparing in advance a base
sheet (24) and an electrostatic dusting sheet (21) which are rolled
up; [0021] guiding the base sheet (24) and the electrostatic
dusting sheet (21) which are rolled up to be continuous to a guide
pulley respectively; [0022] during the process, the electrostatic
dusting sheet (21) is sent through a cutter wheel, whereby a
plurality of triangular fins (7) are carved out on the
electrostatic dusting sheet (21) by the cutter wheel and a
plurality of storage spaces (9) are formed; meanwhile, the margins
of the electrostatic dusting sheet (21) are trimmed by the cutter
wheel and the trimmed-off leftovers are obtained; [0023]
re-incorporating the leftovers of the electrostatic dusting sheet
(21) trimmed to be straps into the process by guiding means, so as
to employ the leftovers as the linings (22) and overlie the linings
on the electrostatic dusting sheet (21) in any required shape
according to the arrangement of the linings (22) mentioned by the
above embodiments; [0024] combining the base sheet (24), the
electrostatic dusting sheet (21), and the linings (22) formed by
the leftovers by fusion to form continuous 3D dusting sheet; [0025]
trimming the prepared continuous 3D dusting sheet by cutting means
to obtain a 3D dusting sheet with a desired length.
[0026] The aforementioned process utilizes fusion means to combine
the base sheet (24), the electrostatic dusting sheet (21), and the
linings (22). However, ultrasonic spot welding may be utilized to
weld the each layer of material by spot for reducing the power
consumption of welding apparatus. Undoubtedly, it is also possible
to secure each layer of material and the linings by physical
stitching means.
[0027] It is preferred that the 3D dusting sheet of the present
invention be used with a mop having a flat panel.
[0028] As for the electrostatic dusting sheet (21), it may be made
of 100% of chemical fiber so as to cause electrostatic phenomenon
spontaneously under friction. In addition, the electrostatic
dusting sheet (21) may be imbued with negative voltage such that
the body or fibers of the electrostatic dusting sheet carry
negative electrons to provide the electrostatic attraction
effect.
[0029] The above embodiments are for better understanding of the
present invention, and the scope of the invention is defined by the
appended claims.
