Description
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- These and other embodiments, aspects and features of the invention will be better understood from a detailed description of the preferred embodiments of the invention, which are further described below in conjunction with the accompanying figures.

Aprotruding edge 131 is disposed at a side edge of a rear segment of thecushion 13 for closely connecting with the closestool body 11 thereby enabling the rear segment of thecushion 13 to produce a better negative pressure effect. Thedeodorization device 20 disposed in the closestool body 11 includes aninspiration hole 21 which is defined in thebackseat surface 111 of the closestool body 11 and at the front of the pivoting position of thecushion 13. Asieve 24 is disposed at theinspiration hole 21 for preventing sundries from falling into theinspiration hole 21. Theinspiration hole 21 is in communication with anexhaust pipe 22 disposed in the closestool body 11. One end of theexhaust pipe 22 is connected to and in communication with adrainage pipe 23 disposed in the closestool body 11. Theexhaust pipe 22 respectively in communication with theinspiration hole 21 and thedrainage pipe 23 is connected with anair pumping device 25. Theexhaust pipe 22 is slanted with an angle to communicate with thedrainage pipe 23 for preventing the excrement in thedrainage pipe 23 from entering theexhaust pipe 22. In the preferred embodiment, a check valve is disposed at a connection segment of theexhaust pipe 22 which is bent from a vertex of theexhaust pipe 22 and is connected to thedrainage pipe 23 for preventing the excrement from entering theexhaust pipe 22. Theair 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, theair pumping device 25 is disposed at the rear segment of the closestool body 11 which is properly elevated.

Amaintenance window 40 is defined in a side surface of the closestool body 11 for facilitating a user to maintain. - In use, the
air pumping device 25 is turned on, and so theinspiration hole 21 is enabled to inspire. Theair pumping device 25 includes afan 251 and acheck valve 252 disposed at one end thereof near thedrainage 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 theexhaust pipe 22 to the air pumping device 15 due to the inhaling force of theinspiration hole 21. The air is inhaled to thefan 251 of theair pumping device 25 and the runningfan 251 exhausts the air passing there through to thecheck valve 252 to enable thecheck valve 252 to open to allow the air to pass there through. Then the air flows through thedrainage pipe 23 and is expelled. When finishing using the deodorization closestool, thepower switch device 30 is turned off, thefan 251 is stopped to run. Thecheck valve 252 returns to a close position. Therefore, the foul odor in the pipe cannot extend through thecheck 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. - Referring to Fig. 4, a deodorization closestool in accordance with a second embodiment of the present invention includes a
