Sensing-Type Lavatory Seat Structure with Covering Film

Abstract

A sensing-type lavatory seat structure with covering film includes a covering film output portion and a covering film collecting portion, a rolling motor and a pivot motor accommodated in a body portion thereof, and a U-shaped seat, through two ends thereof, connected to the covering film output portion and the covering film collecting portion. When the user approaches, a sensing unit senses the situation, controls the pivot motor to lower down the seat and controls the rolling motor to replace the covering film. Then, after the user leaves, the sensing unit once again senses the variation, and controls the pivot motor to lift up the seat to wait for the next time usage.

1 . A sensing-type lavatory seat structure with covering film, comprising a main body having:
 a body portion, a seat, a rolling motor, a pivot motor and a sensing unit, wherein the body portion comprises a covering film output portion and a covering film collecting portion and the rolling motor, and the pivot motor are accommodated in the body portion;   the seat approximately has a U shape and the two ends thereof are respectively connected to the covering film output portion and the covering film collecting portion, wherein the covering film collecting portion is driven by the rolling motor and the seat is driven by the pivot motor, and the sensing unit controls the actions of the rolling motor and the pivot motor; and   thereby, when the user approaches, the sensing unit senses the approaching and sends out signal to control the pivot motor to lower down and also to control the rolling motor to act, so as to replace the covering film.   
   
   
       2 . The structure as claimed in  claim 1 , wherein, when the user leaves, the sensing unit senses the leaving and sends out signal to control the pivot motor to lift up the seat. 
   
   
       3 . The structure as claimed in  claim 1 , wherein the sensing unit is mounted on the body portion. 
   
   
       4 . The structure as claimed in  claim 1 , wherein the sensing unit includes an optical sensing unit for detecting through infrared rays. 
   
   
       5 . The structure as claimed in  claim 1 , wherein the sensing unit comprises a pressure sensing unit for detecting the pressure. 
   
   
       6 . The structure as claimed in  claim 5 , wherein the pressure sensing unit is mounted at the bottom of the seat. 
   
   
       7 . The structure as claimed in  claim 1 , wherein the seat is pivotally connected to a guiding piece for smoothly covering the covering film onto the seat. 
   
   
       8 . The structure as claimed in  claim 1 , wherein the covering film collecting portion has a guiding wheel for smoothly rolling up and collecting the covering film. 
   
   
       9 . The structure as claimed in  claim 1 , wherein the body portion is pivotally connected to a cover for covering the seat. 
   
   
       10 . The structure as claimed in  claim 1 , wherein the body portion has a power supplier mounted therein for providing power to the rolling motor and the pivot motor.
