Toilet Deodorization Device

Abstract

The present invention discloses a toilet deodorization device which belongs to sanitary equipment. An upper side at a rear part of a sitting-type toilet or a squat toilet in a bathroom is pre-built with a hole (by a conventional drill-and-cut technology) to install a connector of the deodorization device. The connector is next connected to an inner vent pipe. Through an air extractor box, a bad odor which is formed when a user is excreting is sucked in and sent to an outdoor structure along a one-way passage, so that the user can be prevented from being contaminated by the bad odor and air in the bathroom can be kept fresh and clean.

What is claimed is: 
     
         1 . A toilet deodorization device comprising:
 a sitting-type toilet or a squat toilet, an upper rim on a rear wall of the toilet is provided with an ventilation hole for installing a connector of the deodorization device;   an inner vent pipe which is hidden in a wall, a lower side of the inner vent pipe is connected to the connector of the deodorization device, the inner vent pipe is extended upward to an air extractor box and is provided with a piping structure to expel upward gas of a bad odor; and   the air extractor box which is a flat and sealed rectangular structure, a center of the air extractor box is provided with air baffles to guide directions of air flow and an upper outlet of the air extractor box is connected to a ventilation outlet of the inner vent pipe.   
     
     
         2 . The toilet deodorization device according to  claim 1 , wherein an upper side at rear edge of a wall of the toilet is provided with a flange to connect from inside to outside the deodorization pipe, an inner and outer part of the flange is provided respectively with a seal washer and the flange is fixed and connected with the inner vent pipe by tightening with a screw cap. 
     
     
         3 . The toilet deodorization device according to  claim 1 , wherein the air extractor box is a flat and sealed rectangular box, a two-third of a width at an upper part of the air extractor box is sealed toward left or a side to provide an upper air baffle, allowing the upper side to form a sealed rectangular air duct; whereas, a two-third of a width at a lower part of the air extractor box is sealed toward right or the other side to provide a lower air baffle, forming another sealed air duct.
