Deodorization closestool
A deodorization closestool 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. The power switch device is connected with the air pumping device for controlling the air pumping device to turn on and off. The deodorization closestool employs the air pumping device disposed in the closestool and the exhaust pipe communicating with the drainage pipe to inhale and expel peculiar smell for preventing the peculiar smell from spilling whereby a washroom can be full of clear air.
(a) Field of the Invention
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
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.
SUMMARY OF THE INVENTIONAn 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.
