Automatic soap dispenser : ウィキペディア英語版 | Automatic soap dispenser
Automatic soap dispensers (also known as touchless or no-touch soap dispensers) dispense a controlled amount of soap solution (or a similar liquid such as a hand sanitizer). They are often used in conjunction with automatic faucets in public restrooms. They function to conserve the amount of soap used and stem infectious disease transmission. ==History== The idea for the first dispenser was submitted by Guey-Chaun Shiau to be patented in 1989. The patent was under the name, “Automatic Cleaning-liquid Dispensing Device”. The patent was issued in 1991. 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.”.〔Huppert, Michael. "Automatic Cleaning-liquid Dispensing Device – ().〕
