CLEANING BRUSH STRUCTURE WITH REPLACEABLE BRUSH HAIR
PLATE
FIELD OF THE INVENTION
The present invention generally relates to cleaning brushes, more
particularly to a cleaning brush structure having a replaceable brush hair
plate.
BACKGROUND OF THE INVENTION
In the area of general cleaning accessories, a brush used for cleaning is
very common to everyone, and one of these cleaning brushes will be described
briefly below.
Please refer to FIG. 1. A cleaning brush 10 comprises a slender rod body
11, a plate member 12 extended from one end of the slender rod body 11, a
brush hair plate 14 integrally coupled onto the plate member 12 to form a
brush
hair plate.
Further, the plate member 12 comprises a metal plate 15 protruded from
the front of the plate member 12 for removing a tough dirt or stain. The brush
hair plate 14 comprises a plurality of brush hairs or scrubbing cloths; and
the
embodiment as shown in FIG. 1 adopts a plurality of brush hairs. Further, the
slender rod body 11 has a handle 16 at the other end to facilitate a user to
hold
the handle for cleaning.
In the manufacturing process of the aforementioned cleaning brush 10, it is
nothing more than simply making a cleaning brush for a particular application,
such as manufacturing the cleaning brush 14 with a plurality of brush hairs or
scrubbing cloths and then integrally coupling the plate member 12 of the
cleaning brush 10 to form a finished goods of the cleaning brush for a single
use. However, the mass production process for producing various different
CA 02484677 2004-10-14
brush hair plates 14 according to the prior arts generally combines the brush
hair plate 14 with a slender rod body 11 and a handle 16 together to fulfill
the
requirements for different applications of the brush hair plate 14, but such
manufacturing method has the following shortcomings.
1. Since the brush hair plate 14 is integrally coupled with the plate member
12 of the cleaning brush 10, therefore the brush hair cannot be replaced after
the brush hair plate 14 has been used for a long time or gets too dirty that
causes problems to the cleaning, or the brush hair plate 14 is damaged.
Users have to buy a brand new cleaning brush for the replacement and thus
increasing the costs.
2. As to the manufacture of the cleaning brushes for various different
applications, a particular type of the slender rod body 11 with a particular
type
of the brush hair plate 14 must be made for each model. Such method not
only wastes time, labor and materials, but also wastes earth resources, and
thus such method is a very inefficient one.
3. If a user needs to use a different cleaning brush for a different cleaning
job, it generally requires the user to buy another kind of cleaning brushes to
meet the need. However, buying all kinds of required brushes not only wastes
money, but also takes up spaces for storing these brushes. It will cause
problems for small family to find a place for storing a number of cleaning
brushes. Therefore, the traditional cleaning brushes have not taken the space
for storage into consideration and are definitely inefficient.
In view of the description above, the plate member 12 of a prior-art
cleaning brush 10 is integrally coupled with the brush hair plate 14, which is
an
issue causing inconvenience to the application by user and requiring
improvements on its design to overcome the existing shortcomings.

SUMMARY OF THE INVENTION
In view of the description above, the design of integrally coupling the plate
body of the cleaning brush with the brush hair plate causes the brush hair
plate
unable to be removed, replaced, or cleaned after a long-time use. Since the
brush hair plate cannot be replaced, therefore users have to buy a new set of
cleaning brush, which not only wastes earth resources, but also has a
drawback of occupying too much storage space. Therefore, based on the
actual requirements of the market and users, the inventor of the present
invention conducted extensive researches and experiments, and finally
invented a cleaning brush structure with a replaceable brush hair plate.
The primary objective of the present invention is to provide a structure for
improving the prior-art design of integrally coupling the plate body and the
brush hair plate that causes the brush hair plate unable to be replaced or
cleaned and creates the problems of wasting resources and creating
inconvenience and troubles to users. With the design of accommodating
groove being tapered in width from its front end. to its rear end. on the
plate
body of the cleaning brush, the baseboard being tapered in width from its
front
end to its rear end, and the opening above the accommodating groove being
slightly smaller than its bottom according to the present invention, the
baseboard can have an advantage of being secured into the accommodating
groove, and thus the baseboard will not fall off easily. In the meantime, the
accommodating groove has an opening being disposed above the
accommodating groove and slightly smaller than the bottom of the
accommodating groove and its rear end is broader than its front end, such that
when a user takes out the baseboard for replacement or cleaning, the
baseboard will not come out uncontrollably due to the excessively applied
force.
In the meantime, the present invention concurrently has the economic effect
CA 02484677 2004-10-14
and complies with the environmental protection 'requirements.
Another objective of the present invention is to build a first latch groove
disposed in the wall at the rear end of the accommodating groove and having
an indented opening, a second latch groove disposed in the wall at the front
end of the accommodating groove, a triangular resilient latch disposed on the
wall at the rear end of the baseboard, and a triangular protruded latch
disposed
on the wall at the front end of the baseboard, such that the baseboard is
embedded into the accommodating groove at an inclined angle, and the
protruded latch can be embedded into the second latch groove and the resilient
latch can be embedded into the first latch groove, and the brush hair plate is
exposed and fixed outside the accommodating groove to define a cleaning
brush head. If it is necessary to remove the baseboard, the resilient latch is
pressed by the indented opening and then the rear end of the baseboard is
lifted up to an inclined angle for a user to take out the baseboard.
The above and, other objects, features and advantages of the present
invention will become apparent from the following detailed description taken
with the accompanying drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 2, 3 and 4 for a cleaning brush structure with a
replaceable brush hair plate of the present invention. The cleaning brush 20
comprises a slender rod body 21, a plate member 22 extended from one end of
the slender rod body 21 and an accommodating groove 23 disposed on one
side of the plate member 22, wherein the accommodating groove 23 is tapered
in width from a front end B1 to a corresponding rear end B2, such that the
internal walls on both sides slightly faces its bottom inside and is inclined
at an
appropriate angle a to define an opening above the accommodating groove 23
and the opening is slightly smaller than the bottom as shown in FIGS. 2 and 3,
and a first latch groove 233 is disposed in a wall at the rear end B2 of the
accommodating groove 23, and an indented opening 234 is disposed on the
first latch groove 233 such that a baseboard 241 of a brush hair plate 24 is
embedded precisely into the accommodating groove 23 and the brush hair
plate 24 is exposed from the accommodating groove 23 to define a cleaning
head, and a second latch groove 235 is disposed in a wall at the front end BI
of the accommodating groove 23 as shown in FIG. 2.
In the present invention, the front end C1 of the baseboard 241 has the
same characteristics as the front end 131 of the accommodating groove 23, of
which the front end C1 of the baseboard 241 is slightly narrower than its
corresponding rear end C2 as shown in FIG. 2, and the two corresponding
sidewalls of the baseboard 241 slightly facing the bottom and the front end C1
are inclined at an appropriate angle P, and a triangular resilient latch 244
(however, the persons skilled in the art may use any other equivalent.
component to substitute this component) is disposed on the wall at the
rear end C2 of the baseboard 241, so that if the baseboard 241 is
5
CA 02484677 2010-04-30
embedded into the accommodating groove 23, the resilient latch 244 will
be embedded precisely into the first latch groove 233 in the wall at the
rear end B2 of the accommodating groove 23. Further, a triangular
protruded latch 245 is disposed on the wall at the front end C1 of the
baseboard 241, such that the protruded latch 245 assists the baseboard
241 to be embedded successfully into the second latch 235 of the
accommodating groove 23. In addition, a metal plate 25 is protruded from
the front of the plate member 22 as shown in FIGS. 2 and 4 for the cleaning
brush 20 to remove a tough dirt or stain. However the persons skilled in
1o the art may use any other equivalent component to substitute the metal
plate 25.
Further, the brush hair plate 24 of the baseboard 241 comprises a
plurality of brush hairs or scrubbing cloths. The embodiments as shown
in the figures adopt the brush hair (however the persons skilled in the art
may use any other equivalent component to substitute this component).
Further, a handle 26 is disposed on the other end of the slender rod body
21 as shown in FIG. 4 as to facilitate users to hold the handle 26 for
performing the cleaning job.
From the special design of the aforementioned accommodating
grooves and the baseboard 241 as shown in FIGS. 2 and 4, it is clear
that the front end C1 of the baseboard 241 enters into the opening from
the rear end B2 to the front end B1 of the accommodating groove 23 at
an appropriate angle, the rear end B2 of the accommodating groove 23 is
slightly broader than its front end 131, and the front end C1 of the
baseboard 241 is slightly narrower than its rear end C2, and the
accommodating groove 23 has an opening slightly smaller than its
bottom and being disposed above the accommodating groove 23.

CA 02484677 2004-10-14
Therefore, the baseboard 241 will be embedded into the accommodating
groove 23 from a looser condition to a tighter condition, such that the
protruded latch 245 in the wall C1 at the front end C1 of the baseboard
241 is latched into the second latch groove 235 in the wall at the front
end 131 of the accommodating groove 23, and finally the protruded latch
245 is pressed down.to latch the resilient latch 244 on the wall of the rear
end C2 of the baseboard 241 precisely into the first latch groove 233 in
the wall at the rear end B2 of the accommodating groove 23 at an
inclined angle as shown in FIG. 3.
On the other hand, if it is necessary to remove the baseboard 241 for
replacement or cleaning, the resilient latch 244 is pressed from the
indented opening 234 of the accommodating groove 23 to lift the rear
end C2 of the baseboard 241 as shown in FIGS. 2 and 4. In the
meantime, since the front end C1 of the baseboard 241 and the front end
B1 of the accommodating groove 23 are in the tightened condition and
have a clamping effect, therefore the baseboard 241 will not be
separated as a whole. Then, the front end C1 of the baseboard 241 is
taken out from the front end 131 of the accommodating groove 23 towards
its rear end B2 to effectively prevent the baseboard 241 from affecting or
endangering the environment when the baseboard 241 flies out due to
the excessive applied force.
In summation of the description above, the special design of the
accommodating groove 23 on the plate member 22 of the cleaning brush
20 working in conjunction with the baseboard 241 of the brush hair plate
24 according to the present invention will have the following advantages.
1. Since the rear end B2 of the accommodating groove 23 is slightly
broader than the front end B1 of the accommodating groove 23 and the
7
CA 02484677 2004-10-14
front end C1 of the baseboard 241 is slightly narrower than the rear end
C2 of the baseboard 241 and the accommodating groove 23 has an
opening being slightly smaller than its bottom and disposed above the
accommodating groove 23, therefore the baseboard 241 can be securely
embedded into the accommodating groove without the risk of being
shaken or falling out.
2. Since the opening above the accommodating groove 23 is
slightly smaller than the bottom of the accommodating groove 23 and the
rear end B2 of the accommodating groove 23 is slightly broader than the
1o front end B1, (in other word, the accommodating groove 23 is tapered in
width from the front end B1 to the rear end B2), therefore users can
effectively prevent the baseboard 241 from flying out due to a possible
excessive applied force that may affect and endanger the environment
when a user takes out the baseboard 241 for replacement or cleaning.
3. A user just needs to change the brush hair plate 24 for the
application of another type of cleaning. The.user does not need to buy
a whole cleaning brush simply for a particular brush hair plate 24 for a
specific application. Such arrangement helps users to save costs.
While the invention has been described by means of specific
embodiments, numerous modifications and variations could be made
thereto by those skilled in the art without departing from the scope and
spirit of the invention set forth in the claims.
