Description
FIELD OF THE INVENTION
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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
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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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
[0010] 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.
[0011] 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
and complies with the environmental protection requirements.
[0012] 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.
[0013] 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
[0018] 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 B1 of the accommodating groove 23 as shown in FIG. 2.
[0019] In the present invention, the front end Cl of the baseboard
241 has the same characteristics as the front end B1 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 .beta., 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 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 15
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 the art may use any other equivalent
component to substitute the metal plate 15.
[0020] 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.
[0021] 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 B1, 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. 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 B1 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.
[0022] 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 B1 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.
[0023] 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 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.
[0024] 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 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.
[0025] 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.
[0026] 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. |
