Description
FIELD OF THE INVENTION
[0001] The present invention relates to a water stopper plug for
sink, and more particularly to a water stopper plug that can be
used in a water stopper base of any sizes.
BACKGROUND OF THE INVENTION
[0002] Conventionally, a water stopping head (70) of a water
stopping head base (60) can be shown in FIGS. 7 and 8, which
includes a main body (71), a fixed rod (72), a water stopping plug
(73) and a nut (74). A receiving space (711) is recessedly formed
in the main body (71), and a plurality of water filtering holes
(712) are in the receiving space (711). A through hole (713) is
formed at the bottom surface of the receiving space (711), and the
through hole (713) can be used to secure the fixed rod (72). The
fixed rod (72) is enlarged in the middle section to form a stopping
edge (721), and a locking pole (722) extends from an upper portion
of the fixed rod (72) to pass through a central through hole (731)
of the water stopping plug (73) and into the through hole (713) of
the water stopper body (71). The locking pole (722) is locked in
the receiving space (711) with the nut (74), so that the water
stopping plug (73) can be disposed between the bottom surface of
the main body (71) and the stopping edge (721) of the fixed rod
(72). A ladder-shaped head (723) located at a lower portion of the
fixed rod (72) can poke through a rotating hole (62) in a water
discharging space (61) of the water stopping base (60).
[0003] When in use, the water stopping head (70) is disposed in the
water discharging space (61) of the water stopper base (60), so the
water stopping plug (73) can be used to block the entire water
discharging space (61) and the dirty water in the sink cannot be
discharged. Meanwhile, the impurities in the dirty water will be
slowly deposited in the receiving space (711) of the main body (71)
to prevent the dirty water from being directly discharged to clog
water pipes. After the impurities are effectively deposited, the
user can use the nut (74) in the receiving space (711) to pull out
the water stopping head (70). With the water discharging channel
that can be temporarily closed and the water stopping head (70)
with filtering function, the water pipe can remain clean and
unblocked to prevent the growth of cockroaches and mosquitoes.
[0004] However, conventional water stopping heads may have problems
such as (i) there are plenty of sinks and water stopper bases (60)
on the market, the water discharging space (61) of different sizes
cause a problem to the customer to choose the water stopping plug
(73) of the same size. The customer may have bought the water
stopping plug (73) that does not match the water stopper bases
(60), so he/she may have to return or change; (ii) the
manufacturers may have to manufacture the water stopping plug (73)
with several different sizes, and each size needs its corresponding
mold, which would increase the manufacturing costs and inventory.
Therefore, there remains a need of a new and improved water
stopping head to overcome the problems illustrated above.
SUMMARY OF THE INVENTION
[0005] The problem to solve in the present invention is that
conventionally the plug of the water stopping head for sink cannot
be used for the water discharging space with different sizes.
[0006] To solve the problem presented above, the present invention
provides a water stopper for sink that is used in a water stopper
base including a water stopper body, a fixed rod, a plug and a
pulling head. A receiving space is recessedly formed in the water
stopper body, and a plurality of water filtering holes are in the
receiving space. A through hole is located at a bottom surface of
the receiving space to secure the insertion of the fixed rod, and
the fixed rod is enlarged in the middle section to form a stopping
edge. A locking pole extends from an upper portion of the fixed rod
to pass through a central through hole of the plug and into the
through hole of the water stopper body. The pulling head can then
lock the locking pole from the receiving space to enable the plug
to be disposed between the bottom surface of the water stopper body
and the stopping edge of the fixed rod, and a ladder-shaped head
located at a lower portion of the fixed rod can poke through a
rotating hole in a water discharging space of the water stopping
base. The plug is a rubber block having a through opening in the
central portion thereof, and a trough is upwardly formed from the
bottom surface of the plug. With the trough, the plug is able to
sustain pressure from every side due to its resilient reformation.
A circular protrusion is formed at an enlarged periphery of the
plug, so that the lower portion of circular protrusion forms a
guiding section, the rear end of which is tapered toward the trough
to form a curved bottom edge.
[0007] Comparing with the conventional arts, the present invention
is advantageous because (i) with the formation of the trough, the
plug can be resiliently deformed, so the plug can be used in the
water stopper base of any sizes, and it is convenient for the
customers to purchase. Also, since the plug can be provided for
most water stopper bases, it is easier and more convenient to
assemble; and (ii) since the plug can be provided for most water
stopper bases, the number of plug with different sizes can be
reduced to lower the costs of the mold and reduce inventory.

intended to represent the only forms in which the present invention
may be prepared or utilized. It is to be understood, rather, that
the same or equivalent functions and components may be accomplished
by different embodiments that are also intended to be encompassed
within the spirit and scope of the invention.
[0017] Unless defined otherwise, all technical and scientific terms
used herein have the same meaning as commonly understood to one of
ordinary skill in the art to which this invention belongs. Although
any methods, devices and materials similar or equivalent to those
described can be used in the practice or testing of the invention,
the exemplary methods, devices and materials are now described.
[0018] All publications mentioned are incorporated by reference for
the purpose of describing and disclosing, for example, the designs
and methodologies that are described in the publications that might
be used in connection with the presently described invention. The
publications listed or discussed above, below and throughout the
text are provided solely for their disclosure prior to the filing
date of the present application. Nothing herein is to be construed
as an admission that the inventors are not entitled to antedate
such disclosure by virtue of prior invention.
[0019] In order to further understand the goal, characteristics and
effect of the present invention, a number of embodiments along with
the drawings are illustrated as following:
[0020] Referring to FIGS. 1 and 2, the present invention provides a
water stopper for sink that is used in a water stopper base (10)
including a water stopper body (20), a fixed rod (30), a plug (40)
and a pulling head (50). A receiving space (21) is recessedly
formed in the water stopper body (20), and a plurality of water
filtering holes (22) are in the receiving space (21). A through
hole (23) is located at a bottom surface of the receiving space
(21) to secure the insertion of the fixed rod (30), and the fixed
rod (30) is enlarged in the middle section to form a stopping edge
(31). A locking pole (32) extends from an upper portion of the
fixed rod (30) to pass through a central through hole (41) of the
plug (40) and into the through hole (23) of the water stopper body
(20). The pulling head (50) can then lock the locking pole (32)
from the receiving space (21) to enable the plug (40) to be
disposed between the bottom surface of the water stopper body (20)
and the stopping edge (31) of the fixed rod (30), and a
ladder-shaped head (33) located at a lower portion of the fixed rod
(30) can poke through a rotating hole (12) in a water discharging
space (11) of the water stopping base (10). The plug (40) is a
rubber block having a through opening (41) in the central portion
thereof, and a trough (42) is upwardly formed from the bottom
surface of the plug (40). With the trough (42), the plug (40) is
able to sustain pressure from every side due to its resilient
reformation. A circular protrusion (43) is formed at an enlarged
periphery of the plug (40), so that the lower portion of circular
protrusion (43) forms a guiding section (44), the rear end of which
is tapered toward the trough (42) to form a curved bottom edge
(45).
[0021] When in use, the water stopper is disposed in the water
discharging space (11) of the water stopper base (10), so the plug
(40) can be used to block the entire water discharging space (11)
and the dirty water in the sink cannot be discharged. Meanwhile,
the impurities in the dirty water will be slowly deposited in the
receiving space (21) of the water stopper body (20) to prevent the
dirty water from being directly discharged to clog water pipes.
After the impurities are effectively deposited, the user can use
the pulling head (50) in the receiving space (21) to pull out the
water stopper. With the water discharging channel that can be
temporarily closed and the water stopper with filtering function,
the water pipe can remain clean and unblocked to prevent the growth
of cockroaches and mosquitoes.
[0022] Furthermore, with the formation of the trough (42), the plug
(40) can be resiliently deformed, so the plug (40) can not only be
used in the water stopper base (10) with a larger water discharging
space (11) (see FIGS. 3 and 4), but also in the water stopper base
(10) with a smaller water discharging space (11) (see FIGS. 5 and
6). When in use, the bottom edge (45) and guiding section (44) with
smaller diameters contact the water discharging space (11) in
order, so that the lower portion of the plug (40) is pressed by the
water discharging space (11) to retract and the plug (40) can be
successfully inserted. After the plug (40) is inserted, the
circular protrusion (43) can be tightly attach to the wall of the
water discharging space (11) due to the resilience and the water
discharging space (11) can be completely blocked by the plug (40),
so the impurities can be filtered in the sink.
[0023] Comparing with the conventional arts, the present invention
is advantageous because (i) with the formation of the trough (42),
the plug (40) can be resiliently deformed, so the plug (40) can be
used in the water stopper base (10) of any sizes, and it is
convenient for the customers to purchase. Also, since the plug (40)
can be provided for most water stopper bases (10), it is easier and
more convenient to assemble; and (ii) since the plug (40) can be
provided for most water stopper bases (10), the number of plug with
different sizes can be reduced to lower the costs of the mold and
reduce inventory.
[0024] Having described the invention by the description and
illustrations above, it should be understood that these are
exemplary of the invention and are not to be considered as
limiting. Accordingly, the invention is not to be considered as
limited by the foregoing description, but includes any
equivalents.
