    Abstract: A toilet bowl is automatically cleaned by a device having an automatic liquid soap dispenser and a guided flow tube. The dispenser is provided with a timer-activated device, and the guided flow tube is connected to the water supply connection of the toilet bowl. The liquid soap is squeezed through the guided flow tube into the water supply connection, thereby allowing the water to be mixed with the liquid soap for flushing and cleaning the toilet bowl.

  • Patent number: 5492247
    Abstract: An automatic soap dispenser having an infrared sensing device and associated circuitry to trigger a driver device into operation. The dynamic power of the device is generated from a motor, through a speed reducing gear to deliver a low speed, high torque driving power to a toothed piece. The toothed piece is driven forward in a direction perpendicular to the soap feeding tube of the soap storage bag, allowing liquid soap in the feeding tube to be squeezed and dispensed for hands cleaning. When the squeezing operation is accomplished, the resiliency of the feeding tube pushes the toothed piece back to its original position and is ready for the next soap dispensing.
