BRUSH STRUCTURE AND A BRISTLE STRUCTURE THEREOF PROVIDING A HIGHLY
EFFECTIVE CLEANING ABILITY
Abstract
A brush structure and a bristle structure thereof are disclosed.
The brush structure comprises a brush body and a bristle structure.
The bristle structure is set up on the brush body and includes a
plurality of bristles. Each bristle has a cleaning structure set up
at the free end of the bristle. The cleaning structure comprises a
plurality of cleaning units. Each cleaning unit has a near end and
a far end relative to the position of the brush body, and the
diameter of the near end is larger than the diameter of the far
end. A circular fillister is formed between each two neighboring
cleaning units. Hence, the bristle structure is able to scrape and
take away the crud from the surface of a cleaned object easily. It
is also easy to wash the jammed crud out of the circular
fillisters. Moreover, the average cross-section area of the
cleaning units is smaller than that of the other part of the
bristle, and thereby the free end of the bristle is soft and not
easily harm the surface of the cleaned object.

Description
FIELD OF INVENTION
[0001] The present invention relates to a brush structure and a
bristle structure thereof, and more particularly, to the brush
structure and the bristle structure thereof providing a highly
effective cleaning ability.
DESCRIPTION OF RELATED ART
[0002] There are many different types of brushes in the present
market, most of the brushes are specified by their cleaning
ability, the cleaning ability is distinguished by the structure of
the bristles, and hence some of the countries have revealed related
patents, for example, the following patents of the Republic of
China (Taiwan): 269780, 272398, 312615, 319683, 344657, 374701,
388708, 414035, 430550, 440439, 1230044 and M281505, and U.S. Pat.
Nos. 4,167,794, 4,317,463, 4,471,505, 5,678,275, 5,926,897,
5,987,691, 6,138,314, 6,276,021, 6,643,886, 6,851,153, 6,886,207,
D483,950 and D487,350 . . . etc.
[0003] In the prior art, the U.S. Pat. No. 5,678,275, "Toothbrush
with bristles having intermediate roughened portion", discloses a
slightly similar structure as the invention described here. The
U.S. Pat. No. 5,678,275 reveals a kind of the structure of the
toothbrush which is consisted of a plurality of bristles and each
of the bristles is consisted of a stabilizing post which is rigidly
attached to the head portion, a plurality of roughened portions on
the post, and a smooth tip at the free end of the post. The
roughened portions are evenly placed on the stabilizing post and
each roughened portion consists of a plurality of grooves. In
general the free ends of the bristles are where get touched with
the cleaned objects, and thereby the free ends of the bristles
should have a strong cleaning ability. In the U.S. Pat. No.
5,678,275, the free end of each bristle is a short cylinder with a
smooth tip; hence this structure does not provide an obvious
cleaning ability.
[0004] In addition strong scraping boards are required to clean the
crud, the scraping boards in the structure of the bristles provided
by the U.S. Pat. No. 5,678,275 are thin and weak, and thereby the
cleaning ability of the bristles is not strong. Furthermore some
small pieces of crud will be stuck in the fillisters because the
fillisters of the bristles are very narrow and deep, and thereof
the crud stuck in the fillisters is very difficult to be cleaned or
washed away.
[0005] The complicated structure of the roughened portions of the
bristles of the U.S. Pat. No. 5,678,275 has a high cost. The main
objective of the present invention is to provide a brush structure
and a bristle structure thereof having a highly effective cleaning
ability and a low cost.
SUMMARY OF THE INVENTION
[0006] One of the objectives of the present invention is to provide
a brush structure and a bristle structure thereof to scrape and
take away the crud from the surface of the cleaned object with a
highly effective cleaning ability.
[0007] One of the objectives of the present invention is to provide
a brush structure and a bristle structure thereof to clean or wash
away the crud jammed on the bristles easily.
[0008] One of the objectives of the present invention is to provide
a brush structure and a bristle structure which can't easily harm
the surface of the cleaned object.
[0009] The present invention provides a brush structure and a
bristle structure thereof with highly effective cleaning ability.
The brush structure includes a brush body and a bristle structure.
The bristle structure is set up on the brush body and includes a
plurality of bristles. Each bristle has a cleaning structure set up
at the free end of the bristle. The cleaning structure includes a
plurality of cleaning units. Each cleaning unit has a near end and
a far end relative to the position of the brush body, and the
diameter of the near end is larger than the diameter of the far
end.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0017] FIG. 1A and FIG. 1B are illustrating the brush structure and
the bristle structure of one of the preferable embodiments of the
present invention. The present invention discloses a brush
structure and a bristle structure thereof with a highly effective
cleaning ability. The brush structure 1 comprises a brush body 10
and a bristle structure 12, and the bristle structure 12 is set up
on the brush body 10. The bristle structure12 comprises a plurality
of bristles 121, and each bristle 121 has a cleaning structure 123
which is set up at the free end of the bristle 121. On the bristle
121, the free end is on the opposite side to the brush body 10.
Each cleaning structure 123 comprises a plurality of cleaning units
1231. Each cleaning unit 1231 has a near end 12311 and a far end
12313 relative to the position of the brush body 10. The diameter
of the near end 12311 is larger than the diameter of the far end
12313. On each bristle 121, all the cleaning units 1231 are
connected to form the cleaning structure 123. A circular fillister
1233 is formed between each two neighboring cleaning units 1231.
Owing to several circular fillisters 1233 existing at the free end
of each bristle 121, the brush structure 1 is able to scrape the
crud from the surface of the cleaned object and take away the crud
easily, and therefore the brush structure 1 of the present
invention has a highly effective cleaning ability. Because the
circular fillisters 1233 are wide and open, it is easy to wash away
the crud jammed in the circular fillisters 1233; this is another
one of the characteristics of the present invention. Because all
the cleaning units 1231 have a smaller average cross-section area
than that of the other part of the bristle 121, the cleaning
structure 123 on each bristle 121 is soft and thereby not easily
harm the surface of the cleaned object.
[0018] FIG. 2 is illustrating the bristle structure of another
preferable embodiment of the present invention. The present
invention discloses a brush structure and a brittle structure
thereof with a highly effective cleaning ability. The brush
structure 1 (shown in FIG.1) comprises a brush body 10 and a
bristle structure 12, and the bristle structure 12 is set on the
brush body 10. The bristle structure 12 comprises a plurality of
bristles 121, and each bristle 121 has a cleaning structure 123.
The cleaning structure 123 is set up at the free end of the bristle
121. The cleaning structure 123 comprises a plurality of cleaning
units 1231, each cleaning unit 1231 has a near end 12311 and a far
end 12313 relative to the position of the brush body, and the
diameter of the near end 12311 is larger than the diameter of the
far end 12313. The difference between the cleaning units 1231 in
this embodiment and that in FIG. 1B is that a smooth round 125 is
set up on the convex edge of each cleaning unit 1231, and a smooth
fillet 127 is set up on the concave edge of each circular fillister
1233 which is formed between each two neighbouring cleaning units
1231. Because of the smooth round 125 on the convex edge of each
cleaning unit 1231, the brush structure 1 with the cleaning units
1231 shown in FIG. 2 of the prevent invention can prevent the edge
of the cleaning units 1231 from harming the surface of the cleaned
object. The smooth fillet 127 formed between each two neighboring
cleaning units 1231 can prevent the crud from sticking in the
circular fillister 1233, and hence makes the brush structure 1 easy
to clean up.
[0019] FIG. 3 and FIG. 4 are illustrating the cleaning units of
another two preferable embodiments of the present invention. As
shown in FIG. 3 and FIG. 4, each cleaning unit 1231 has a near end
12311 and a far end 12313 relative to the position of the brush
body 10, and the diameter of the near end 12311 is larger than the
diameter of the far end 12313. The lateral surfaces of the cleaning
units 1231 in FIG. 1B, FIG. 5, FIG. 6 and FIG. 7 are revolved by
straight line or line segments, but the lateral surfaces of the
cleaning units 1231 in FIG. 3 and FIG. 4 are revolved by curves.
The lateral surfaces of the cleaning units 1231 in FIG. 3 are
convex, but the lateral surfaces of the cleaning units 1231 in FIG.
4 are concave, and thereby the cleaning units 1231 in FIG. 4 can
store more crud than the cleaning units 1231 in FIG. 3. The
cleaning units 1231 shown in FIG. 3 and FIG. 4 can also be applied
to the embodiment shown in FIG. 2.
[0020] FIG. 5, FIG. 6 and FIG. 7 are illustrating diagrams of three
other preferable embodiments of the present invention. Each of
these cleaning units 1231 has a near end and a far end relative to
the position of the brush body, and the diameter of the near end is
larger than the diameter of the far end. The cleaning units 1231 in
FIG. 5, FIG. 6 and
[0021] FIG. 7 are different to the cleaning unit 1231 in FIG. 1B
because the cleaning units 1231 in FIG. 5, FIG. 6 and FIG. 7 are
revolved by line segments, and can also be applied to the
embodiment shown in FIG. 2.
[0022] The present invention provides a brush structure and a
bristle structure thereof with highly effective cleaning ability.
The characteristic of the present invention is in the bristle
structure which includes a plurality of bristles. Each bristle has
a cleaning structure set up at the free end of the bristle, and the
free end is on the opposite side to the brush body. The cleaning
structure includes a plurality of cleaning units. Each cleaning
unit has a near end and a far end relative to the position of the
brush body, and the diameter of the near end is larger than the
diameter of the far end. A circular fillister is formed between
each two neighboring cleaning units. Due to several circular
fillisters being placed at the free end of each bristle, the brush
structure is able to clean and take the crud away from the surface
of the cleaned object easily. Because the circular fillisters are
wide and open, it is also easy to wash away the crud jammed in the
circular fillisters. The average cross-section area of the cleaning
units is smaller than that of the other part of the bristle, so the
free end of each bristle is soft and thereby not easily harm the
surface of the cleaned object. The brush structure provided in the
present invention can be applied to all types of brushes such as
toothbrushes, cleaning brushes or any other type of brush.
[0023] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention covers modifications and variations of this
invention provided they fall within the scope of the following
claims and their equivalents.
