BACKGROUND OF THE INVENTION
(a) Field of the Invention
[0001] The present invention relates to a deodorization closestool, and particularly to
a deodorization closestool which employs a deodorization device disposed in the closestool
to effectively eliminate the foul odor of excrement in the closestool for improving
the air quality of a washroom.
(b) Description of the Invention
[0002] It is a necessary physiological activity for everyone to go to the washroom at daily
living. An excrement naturally has peculiar smell, foul odor and even unacceptable
smell due to some kinds of food. The uncomfortable smell not only remains in a closestool,
but also spills in the washroom, which is embarrassed or uncomfortable to users.
[0003] Nowadays, aromatizes are often disposed in a washroom to produce aroma for mixing
with and covering the foul odor produced by the excrement. However, the washroom is
still full of the foul odor and so the foul odor is not completely eliminated. Furthermore,
it is required to replace the aromatizes to keep the aroma in the washroom when the
aromatizes are used up. Therefore, it is high cost. In another way, a deodorizer is
dropped in a closestool before and after using the closestool for neutralizing the
foul odor produced by the excrement with the deodorizer thereby eliminating the foul
odor. However, it is inconvenient to use and also high cost.
[0004] In addition, a fan is disposed at a wall of the washroom for removing the foul odor
to the outside of the washroom. However, since the fan is quite far away from the
closestool, the removing effect of the fan is limited. Furthermore, the washroom is
full of foul odor during using the closestool and so the effect of the fan to remove
the foul odor is poor. Another manner is to employ a pipe to connect between the fan
disposed at the wall and a back seat of the closestool. However, it requires to additionally
dispose a pipe and so it is also inconvenient to use.
SUMMARY OF THE INVENTION
[0005] An object of the present invention is to provide a deodorization closestool which
employs an air pumping device disposed in the closestool and an exhaust pipe communicating
with a drainage pipe to inhale and expel peculiar smell for preventing the peculiar
smell from spilling whereby a washroom can be full of clear air.
[0006] Another object of the present invention is to provide a deodorization closestool
which is integrally formed with an air pumping device and an exhaust pipe being disposed
in the closestool.
[0007] A further object of the present invention is to provide a deodorization closestool
which disposes a power switch device at the closestool for facilitating a user to
control at any moment.
[0008] A further object of the present invention is to provide a deodorization closestool
which is defined with a maintenance window at a side surface of the closestool for
facilitating a user to maintain.
[0009] A further object of the present invention is to provide a deodorization closestool
which communicates and combines an exhaust pipe and a drainage pipe thereby overcoming
the inconvenient installation of pipes of a conventional deodorization closestool
and saving space occupied by the pipes.
[0010] To achieve the above objects, a deodorization closestool of the present invention
includes a closestool device comprising a closestool body, a deodorization device
disposed in the closestool body, and a power switch device disposed in the closestool
body. The deodorization device includes an air pumping device which inspires from
an inspiration hole through an exhaust pipe. The inspiration hole is defined in a
proper position of the closestool body. One end of the exhaust pipe communicates a
drainage pipe of the closestool body. At least one check valve is disposed between
the exhaust pipe and the drainage pipe. The power switch device is connected with
the air pumping device for controlling the air pumping device to turn on and off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Referring to Figs. 1 and 2, a deodorization closestool in accordance with a preferred
embodiment of the present invention includes a closestool device 10, a deodorization
device 20 and a power switch device 30. The closestool device 10 includes a closestool
body 11 and a water tank 12. A cushion 13 and a closestool cover 14 are pivotably
disposed at a backseat surface 111 of the closestool body 11. A protruding edge 131
is disposed at a side edge of a rear segment of the cushion 13 for closely connecting
with the closestool body 11 thereby enabling the rear segment of the cushion 13 to
produce a better negative pressure effect. The deodorization device 20 disposed in
the closestool body 11 includes an inspiration hole 21 which is defined in the backseat
surface 111 of the closestool body 11 and at the front of the pivoting position of
the cushion 13. A sieve 24 is disposed at the inspiration hole 21 for preventing sundries
from falling into the inspiration hole 21. The inspiration hole 21 is in communication
with an exhaust pipe 22 disposed in the closestool body 11. One end of the exhaust
pipe 22 is connected to and in communication with a drainage pipe 23 disposed in the
closestool body 11. The exhaust pipe 22 respectively in communication with the inspiration
hole 21 and the drainage pipe 23 is connected with an air pumping device 25. The exhaust
pipe 22 is slanted with an angle to communicate with the drainage pipe 23 for preventing
the excrement in the drainage pipe 23 from entering the exhaust pipe 22. In the preferred
embodiment, a check valve is disposed at a connection segment of the exhaust pipe
22 which is bent from a vertex of the exhaust pipe 22 and is connected to the drainage
pipe 23 for preventing the excrement from entering the exhaust pipe 22. The air pumping
device 25 may be configured to be higher than the height of the maximum water level
of the pool of the closestool body 11. For example, the air pumping device 25 is disposed
at the rear segment of the closestool body 11 which is properly elevated. The power
switch device 30 is disposed in the closestool body 11 and connected to the air pumping
device 25 for controlling to turn on or off the air pumping device 25. The power switch
device 30 is connected to the air pumping device 25 through a power line 31. A maintenance
window 40 is defined in a side surface of the closestool body 11 for facilitating
a user to maintain.
[0014] In use, the air pumping device 25 is turned on, and so the inspiration hole 21 is
enabled to inspire. The air pumping device 25 includes a fan 251 and a check valve
252 disposed at one end thereof near the drainage pipe 23. Also referring to Figs.
3A and 3B, when the deodorization closestool of the present invention is used, smell
of the excrement in the closestool body 11 is inhaled along the exhaust pipe 22 to
the air pumping device 15 due to the inhaling force of the inspiration hole 21. The
air is inhaled to the fan 251 of the air pumping device 25 and the running fan 251
exhausts the air passing there through to the check valve 252 to enable the check
valve 252 to open to allow the air to pass there through. Then the air flows through
the drainage pipe 23 and is expelled. When finishing using the deodorization closestool,
the power switch device 30 is turned off, the fan 251 is stopped to run. The check
valve 252 returns to a close position. Therefore, the foul odor in the pipe cannot
extend through the check valve 252 in a reversed direction. Thus, a user can avoid
to smell the odor of the excrement during using the deodorization closestool, and
the latter user also can avoid to smell the odor of the excrement of the former user
thereby maintaining better quality of air in the washroom.
