BACKGROUND OF THE INVENTION

(a) Field of the Invention

The invention relates to a stool device having deodorization function, and more particularly, to a stool device having an appropriate routing pipeline for eliminating odor sources, thereby preventing disturbances caused by a lavatory in use and ensuring good air quality in the lavatory.

(b) Description of the Prior Art

Excretion and defecation are natural physical activities of human beings. It is inevitable that excretion after biological reactions has foul smells and may even be as bad as unbearable due to diet reasons. Discomfort caused by such odors not only exists when one excretes in a lavatory, but also incurs disturbances and irritations a subsequent user of the lavatory. The aforesaid occurrence is embarrassing for both precedent and subsequent users of the toilet. Although an exhaust fan can be installed in the lavatory to discharge air, it is yet unavoidable for the user to bear the odors owing to a position of the exhaust fan and airflows. In addition, odors from excretion are likely diffused into air, and thus the odors can only be gradually eliminated with a certain period of ventilation operation using the fan after excretion, meaning that the subsequent user remains inescapable from the disturbances and discomforts caused by the odors. Having to confront torment by daily physical behavior, it is essential task of industrialist to provide a solution that effectively solves the aforesaid issues.

In view of the aforesaid issues of disturbances caused be excretion odors and unsatisfactory design of prior stools, the invention provides a stool device having deodorization function for offering better hygiene and comfort.

SUMMARY OF THE INVENTION

The primary object of the invention is to provide a stool device having deodorization function, in that the a stool device is capable of rapidly eliminating foul smells and odors from excretion and defecation, thereby preventing disturbances when using a lavatory as well as maintaining good air quality of the lavatory.

To accomplish the aforesaid object, a stool device having deodorization function according to the invention comprises a stool body and a deodorizing device. The deodorizing device has an exhaust fan that draws air from an air inlet via a routing pipeline, and an air inlet located at an appropriate position of the stool body and for rapidly drawing odors of excretion that is further discharged via the routing pipeline.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To better understand objects, technical characteristics and effects of the invention, detailed descriptions shall be given with the accompanying drawings below.

Referring to FIG. 1 showing a stool device having deodorization function in a first embodiment according to the invention, the invention comprises a stool device 10 and a deodorizing device 20. The stool device 10 has a stool body 11, a water closet 12, and a seat 13 and a stool cover 14 pivotally disposed at a rear seat plane 111 of the stool body 11. The seat 13 has a rear side thereof disposed with a protruding edge 131 for closely joining with the stool body 11, so as to provide a rear section of the seat 13 with optimal anti-pressure effects. The deodorizing device 20 has an air inlet 21 located at the rear seat plane 111 of the stool body 11 and also at a front edge of a pivotal joint of the seat 13; a discharging channel 22 connected with the air inlet 21 and located in the stool body 11; a discharging pipeline 23 in communication and connected with the discharging channel 22, and located between a floor and a wall; an exhaust fan 24 disposed at an appropriate position at an upper end of the discharging pipeline 23, and also usually located at a ceiling; and a filter 26 devised at the air inlet 26 and for preventing incoming of alien objects.

To put the stool device having deodorization function according to the invention to use, the exhaust fan 24 is first activated to allow the air inlet with air drawing effects. When one is at the lavatory, odors of excretion in the stool body 11 are rapidly drawn by suction forces of the air inlet 21, and are discharged via the discharging channel 22 and the discharging pipeline 23 in sequence. Not only a user is free from disturbances caused by the lavatory in use, but also a subsequent user is prevented from perplexities incurred by odors from a precedent user, thereby ensuring enhanced sanitary quality of the lavatory.

Referring to FIG. 2 showing a stool device having deodorization function in a first embodiment according to the invention, the invention comprises a stool device 10 and a deodorizing device 30. The stool device 10 has a stool body 11, a water closet 12, and a seat 13 and a stool cover 14 pivotally disposed at a rear seat plane 111 of the stool body 11. The seat 13 has a rear side thereof disposed with a protruding edge 131 for closely joining with the stool body 11. The deodorizing device 30 has an air inlet 312 located at the rear seat plane 111 of the stool body 11; a discharging channel 32 connected with the air inlet 312 and located in the stool body 11; a discharging pipeline 33 in communication and connected with the discharging channel 32, and located between a floor and a wall; an exhaust fan 34 disposed at an appropriate position at an upper end of the discharging pipeline 33; and a flat air inlet tube 31 in communication and connected with the air inlet 312, located behind the rear seat plane 111 of the stool body 11, having an air inlet opening 311 and serving for discharging odors from using the lavatory via the routing pipeline.

Referring to FIG. 3 showing a stool device having deodorization function in a third embodiment according to the invention, the invention comprises a stool device 10 and a deodorizing device 40. The stool device 40 a stool body 11, a water closet 12, and a seat 13 and a stool cover 14, wherein the seat 13 has a groove 132 at a rear lower edge thereof. The deodorizing device 40 has an air inlet tube 41 embedded at the groove 132 of the seat 13. When the seat 13 is lowered, the air inlet tube 41 in form of a flat structure is located at the rear seat plane 111 of the stool body 11; and has a front end thereof provided with an air inlet opening 411 for drawing odors from using the lavatory, and a rear end thereof provided with a flexible joint 412 for connecting to a discharging channel 42 of the stool body 11, wherein the discharging channel 42 is connected with a discharging pipeline 43 and guided by a tube of an exhaust fan 44.

Referring to FIGS. 4A and 4B showing a stool device having deodorization function in a fourth embodiment according to the invention, the invention comprises a stool device 10 and a deodorizing device 50. The stool device 10 has a stool body 11, a water closet 12, and a seat 13 and a stool cover 14. The seat 13 has a lower rear side thereof disposed with a sealed section 130, which is provided with an inlet groove 134 in form of an open groove at an inner side thereof and a groove opening 133.
