Automatic sanitary film dispensing system for toilet

Abstract

An automatic sanitary film dispensing system includes a supply barrel and a take-up barrel respectively mounted on the front and rear sides of the toilet seat of a toilet, a DC motor mounted in one end of the take-up barrel, a take-up reel pivotally mounted in the other end of the take-up barrel and rotatable manually through a crank handle, a roll of sanitary film rotatably mounted in the supply-barrel and having a slat fixedly fastened to the lead end and connectable between the output shaft of the DC motor and the take-up spindle of the take-up reel for rotation by the DC motor to take up the sanitary film, the sanitary film having cut line portions equally spaced along the length, each cut line portion being tearable to define an oval hole in the sanitary film corresponding to the cavity of the bowl of the toilet in which the toilet seat is installed, and a sensor for detecting the presence of a human being and controlling the DC motor to rotate through a predetermined number of turns when detected a signal.

1 . An automatic sanitary film dispensing system comprising:
 a toilet seat pivoted to the bowl of a toilet for the sitting of a person using the toilet, said toilet seat having a plurality of mounting holes symmetrically disposed at two opposite lateral sides thereof;   a supply barrel mounted on a front side of said toilet seat, said supply barrel having a plurality of arms extending from the periphery thereof and respectively fastened to the mounting holes of said toilet seat, a longitudinal crevice cut through the periphery and longitudinally extending through two opposite open ends thereof, and two end caps detachably capped on the two opposite open ends;   a take-up barrel mounted on a rear side of said toilet seat, said take-up barrel having a hinged cover, said hinged cover defining with the periphery of said take-up barrel a longitudinal crevice when said hinged cover is closed;   a DC motor mounted in one end of said take-up barrel, said DC motor having an output shaft suspending in the associated end of said take-up barrel;   a take-up reel pivotally mounted in an opposite end of said take-up barrel, said take-up reel having a take-up spindle suspending in the associated end of said take-up barrel;   a crank handle connected to said take-up reel and extending out of said take-up reel for operation by a person to rotate said take-up reel;   a roll of sanitary film rotatably mounted in said supply-barrel between said end caps, said sanitary film having a lead end extending out of the longitudinal crevice of said supply barrel and insertable through the longitudinal crevice of said take-up barrel, a slat fixedly fastened to said lead end and connectable between the output shaft of said DC motor and the take-up spindle of said take-up reel for rotation with said output shaft of said DC motor and the take-up spindle of said take-up reel to take up said sanitary film, and a plurality of cut line portions equally spaced along the length thereof, each said cut line portion being tearable to define an oval hole in said sanitary film corresponding to the cavity of the bowl of the toilet in which said toilet seat is installed; and   a sensor mounted in said take-up barrel and electrically connected to said DC motor and adapted for detecting the presence of a human being and controlling said DC motor to rotate through a predetermined number of turns when detected a signal.   
   
   
       2 . The automatic sanitary film dispensing system as claimed in  claim 1 , wherein each said end cap has a center pivot pin suspending inside said supply barrel for supporting said roll of sanitary film in said supply barrel. 
   
   
       3 . The automatic sanitary film dispensing system as claimed in  claim 1 , further comprising a rechargeable battery electrically connected to said DC motor and said sensor.
