Deodorization closestool

Abstract

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.

1 . A deodorization closestool comprising: 
 a closestool device comprising a closestool body;    a deodorization device disposed in the closestool body, the deodorization device comprising an air pumping device which inspires from an inspiration hole through an exhaust pipe, the inspiration hole being defined in a proper position of the closestool body, one end of the exhaust pipe communicating a drainage pipe of the closestool body, at least one check valve being disposed between the exhaust pipe and the drainage pipe; and    a power switch device disposed in the closestool body and connecting the air pumping device, the power switch device being adapted for controlling the air pumping device to turn on and off.    
   
   
       2 . The deodorization closestool of  claim 1 , wherein a cushion and a closetool cover are pivotably disposed at the backseat surface of the closestool body.  
   
   
       3 . The deodorization closestool of  claim 2 , wherein the inspiration hole is defined in the backseat surface of the closestool body.  
   
   
       4 . The deodorization closestool of  claim 1 , wherein the inspiration hole is communicated with the exhaust pipe disposed in the closestool body.  
   
   
       5 . The deodorization closestool of  claim 1 , wherein the height of the air pumping device is higher than that of maximum water level of the pool of the closestool body.  
   
   
       6 . The deodorization closestool of  claim 1 , wherein a sieve is disposed at the inspiration hole for preventing sundries from falling into the inspiration hole.  
   
   
       7 . The deodorization closestool of  claim 2 , wherein a protruding edge is disposed at the side edge of the rear segment of the cushion.  
   
   
       8 . The deodorization closestool of  claim 2 , wherein a recess is defined in the bottom edge of the rear end of the cushion for positioning an inspiration pipe.  
   
   
       9 . The deodorization closestool of  claim 2 , wherein a through groove is defined in the bottom edge of the rear end of the cushion for positioning an inspiration pipe.  
   
   
       10 . The deodorization closestool of  claim 1 , wherein a maintenance window is defined in the side surface of the closestool body for facilitating a user to maintain the deodorization closestool.  
   
   
       11 . The deodorization closestool of  claim 1 , wherein the power switch device is connected with the air pumping device through a power line.  
   
   
       12 . The deodorization closestool of  claim 1 , wherein the exhaust pipe is slanted with an angle to communicate with the drainage pipe for preventing excrement in the drainage pipe from entering the exhaust pipe.  
   
   
       13 . The deodorization closestool of  claim 1 , wherein the air pumping device includes a fan and a check valve disposed at one end thereof near the drainage pipe.  
   
   
       14 . The deodorization closestool of  claim 1 , wherein the air pumping device and the exhaust pipe are disposed in a groove in the edge of the seat surface of the closestool body.
