Automatic soap dispenser

The patented device was under the following description: "An automatic cleaning-fluid dispensing device includes: a containing structure for containing cleaning fluid; a sensing device disposed on a base member being installed in the lower portion of said containing structure wherein said base member is provided with an outlet, a sensing circuit disposed on a circuit board, a motor arrangement electrically connected to the sensing circuit, an outlet for passing a light source of the sensing circuit therefrom so as to detect the presence of an external object closing on the light source; and a dispensing mechanism, which is composed of a push structure functionally connected with the driving motor and a pumping structure operatively engaged with the push structure, installed on the base member in connection with the sensing device; whereby when an external object closes to the sensing device, a given amount of the contained cleaning fluid in the containing structure will be automatically supplied for cleaning purposes.".

An increasing number of public locations and private institutions have been incorporating touchless technology into their washrooms.

Journalist Michael Sasso once termed it as, "Hygienic Company Brings Space Age to Bathroom."

A study was conducted in the accession area of the clinical microbiology laboratory and the outpatient dentistry department of the University of Virginia Medical Center.

[4] The advances of hygiene, such as that of the automatic soap dispenser, can be considered as one of the more silent victories of public health and continues to be an important disease prevention strategy, even in this "modern" era when the "gospel of germs" has waned in popularity.

[5] A strong corollary in the decline of the mortality rate is that of hand-washing (National Center for Health Statistics).

When hands are placed in the basin, the energy emitted from the sensor will bounce back irregularly which triggers the dispensation of soap.

When no hands are present in front of the device, no reflection of light takes place, and therefore, no pulse is sensed.

These colonies will interbreed and lead to a more resistant strain of bacteria that can re-contaminate different hands and would not be completely eliminated by the anti-bacterial soap.
