Toilet paper supply machine and identifiable toilet paper roll

Abstract

The present utility model provides a toilet paper supply machine and identifiable toilet paper roll, in which the toilet paper roll supporting base of a supply machine body is provided with a motion sensing device, and two ends of the toilet paper roll each is associated with a cover tube, in which one outer tube portion of one cover tube is provided with a through hole, through which the toilet paper roll is mounted to the supply machine body, such that when the motion sensing device is covered by the outer tube, the motion sensing device can identify the through hole; in addition, a cutting device arranged within the supply machine body is further provided with a stopping device, in the case when the motion sensing device senses that the toilet paper roll is an incorrect one or an unqualified one, the stopping device is started to stop the cutting device, such that the cutting device is stopped from cutting the toilet paper. In this way, the present utility model is able to protect the toilet paper supply machine.

What is claimed is: 
     
         1 . A toilet paper supply machine, in which a toilet paper roll can be inserted, and the toilet paper supply machine is able to cut the inserted toilet paper roll to provide a piece of toilet paper, wherein the toilet paper supply machine comprises:
 a supply machine body comprising:
 a rear base for wall mounting; 
 a front cover movably pivoted in front of the rear base; 
 a paper outlet opening is provided below or in front of the front cover; 
 two integral or assembled paper roll supporting bases provided in front of the rear base, wherein a storage space for storing a toilet paper roll is provided between the two paper roll supporting bases; 
 a cutting device for cutting the toilet paper, wherein the cutting device is arranged in front of the rear base and below the two paper roll supporting bases, and wherein one side of the cutting device is provided with a manual knob rotating synchronously with the cutting device; 
 a motion sensing device, wherein the motion sensing device is arranged on an inner surface of one of the two paper roll supporting bases; and 
 a protruding ring provided in a center of one end of the toilet paper roll, wherein the protruding ring is provided with at least one through hole through which the motion sensing device can sense, wherein the toilet paper roll is placed between the two paper roll supporting bases, and wherein the through hole is adjacent to the motion sensing device to allow the motion sensing device to sense via the through hole. 
   
     
     
         2 . The toilet paper supply machine according to  claim 1 , further comprising two cover tubes, each cover tube comprising an inner tube portion adapted to insert into a paper tube located in the center of the toilet paper roll, and an outer tube portion protruding from one end of the toilet paper roll, wherein the outer tube portion of at least one cover tube is provided with the through hole to form the protruding ring, and the protruding ring covers the motion sensing device. 
     
     
         3 . The toilet paper supply machine according to  claim 2 , wherein the through hole is a through hole radially penetrating the outer tube, and the outer tube is provided with a plurality of the through holes. 
     
     
         4 . The toilet paper supply machine according to  claim 2 , wherein the motion sensing device is an infrared sensor comprising a transmitter and a receiver. 
     
     
         5 . The toilet paper supply machine according to  claim 1 , further comprising a stopping device, wherein the stopping device comprises a motor which is arranged on one side of the cutting device, a reduction gear set which is arranged on one side of the cutting device and driven by the motor, and a hindering element driven by the reduction gear set; and a hindering portion provided on one side of the manual knob, a hindering bar of the hindering element is adapted to stop the hindering portion to stop the cutting device from cutting the paper. 
     
     
         6 . The toilet paper supply machine according to  claim 5 , wherein the hindering element is a sector gear, and the hindering bar protrudes from one side of the sector gear. 
     
     
         7 . The toilet paper supply machine according to  claim 5 , wherein the stopping device further comprises a housing, the housing is fixed outside of the paper roll supporting base, the reduction gear is set and the hindering element are disposed within the housing, and the hindering bar of the hindering element protrude from the housing. 
     
     
         8 . The toilet paper supply machine according to  claim 5 , further comprising a controller, wherein the controller is connected to the infrared sensor and the motor. 
     
     
         9 . The toilet paper supply machine according to  claim 8 , further comprising a battery power supply unit, wherein the battery power supply unit is connected to the controller. 
     
     
         10 . An identifiable toilet paper roll, comprising:
 a toilet paper roll which comprises a paper tube and toilet paper wound thereon;   
       and two cover tubes, the two cover tubes each comprising an inner tube portion adapted to insert into the paper tube located in the center of one end of the toilet paper roll, and an outer tube portion protruding from one end of the toilet paper roll, wherein the outer tube portion of one cover tube is provided with a through hole to allow a motion sensing device to sense via the through hole.
