Description

DE~DORIZATION CLOSEST40L
FTELD OF THE INVENTION
The present invention relates to a deadorization closestool, and particularly to a dcodorization closestool which employs a deodorizatian device disposed in the closestool to el~eetively ciirninate the foul odor of excrement in the clasestaal far improving the air quality of a washraam.
BACKCE~QUlI_p OF TAE INVENTION
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 same kinds of food. The uncomfortable smell nat anly remains in a closestool, but also spills in the washroom, which is embarrassed or uneprnfartable to users.
Nowadays, aromatizers are often disposed in a washroom to produce aroma for mixing with and covering the foul odor produced by the excrement. 1-(owever, the washxoom is still full of the foul odar and so the foul odor is rzot completely eliminated. Furthermore, it is .required to replace the aromatizers to keep the aroma in the washroom when the aromatizers are used up. "therefore, it is high cost. rn another way, a deodorizer is dropped in a clasestaol before and after using the closestool for neutralizing the foul odor produced by the excrement with r the deodorizer thereby eliminating the foul odor. However, it is inconvenient to use and also high cost.
In addition, a fan is disposed at a wall ofthe washroom for remaving the foul odor to the outside of the washroom. However, since the fan is quite far away fram the closestool, the removing effect a.f the fan is limited. Furthermore, the washraam is full of foul odor during using the elosestool 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.

DIETAILED DESCRIPTION OF THE PREF)~RRED EMBODIMENTS
Referring to Figs. 1 and 2, a deodorization elosestvol in accordance with a preferred embodiment of the present invention includes a cl4scstool device 10, a deadorizatian device 20 and a power switch device 30. T'he closestool device 10 includes a closestoal bady 1 l and a water tank I2. A cushion 13 and a closcstool cover I4 are pivatably disposed at a backseat surface 111 of the closestoal body 11. A protruding edge 1.31 is disposed at a side edge of a rear segment of the cushion 13 far closely connecting with the closescoal body i 1 thereby enabling the rear segment of the cushion 13 to produce a better negative pressure effect. The i5 deodorization device 20 disposod in the closestool body 11 includes an inspiration hole 21 which is defined in the backsoat surface 111 of the closestool body 11 and at the tiont of the pivoting position of the cushion 13. A sieve 24 is disposed at the inspiration hole 2I
for preventing sundries from falling into the inspiration hole 21. The inspiration hale 2i is in communication with an exhaust pipe 22 disposod in the closcstool body 11. One e~~d of thr:
exhaust pipe 22 is canni~c;ted to and in communication with a drainage pipe 23 disposed in the clascstoo( body 11.
The exhaust pipe 22 respectively in communication with the inspiration halo 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 presenting the excrement in the drainage pipe 23 from entering the exhaust pipe 22. In the preferred r,~rnbodiment, a check valve is disposed at a connection se~nent of the exhaust pipe 22 which is bent (rorn a vertex of the exhaust pipo 22 and is connect~l to the drainage pipe 23 for preventing the excrement from entearing the exhaust pipe 22. The air pumping device 25 may be canFrgur~ to be higtler than the height of the maximum water level of the pool of the closestaol body 11, l~or example, the air pumping device 25 is disposed at the rear segment of the clasestaol bady 11 which is properly elevated. The power switch device 30 is disposed in the closestool body 1 l and connected to the air pumping device 25 for contraliing to turn on or oil 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 1. I
far facilitating a user to maintain.
In use, the air pumping device 25 is turned on, and so the inspiration bole 21 is enabled to inspire. "r'he 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 farce of the inspiration hole 21. The air is inhaled to the fan 251 of the air pumping device 25 and the I 5 running fan 251 exhausts the air passing thercthrough to the check valve 252 to enable the check valve 252 to open to allow the air to pass therethrough. Then tfle air haws through the drainage pipe 23 and is expelled. When finishing using the deodorization clasestool, 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 deodorizatian cla5estool, and the latter user also can avoid to smell the odor of the excrement of the former user thereby maintaihing better quality of air in the washroom.
