HYGIENIC SHEET MATERIAL DISPENSER

摘要

A hygienic sheet material dispenser includes a housing with a dispensing opening, a compartment for a sheet material product, a first sensor arranged to assume an active mode in which it scans for the presence of a user, a dispensing motor arranged to drive a driving mechanism, a second sensor for sensing when a piece of said product has been removed, and a microcontroller connected to the first sensor, the second sensor and the dispensing motor, said dispenser also being configured to be switched to a passive mode. The dispenser is arranged to switch to the passive mode after a first predetermined period of time has elapsed in the active mode without detection of a user; wherein, upon entering the passive mode, a length of said product is fed from the dispenser out of the dispensing opening and the first sensor and the microcontroller are substantially deactivated; and wherein the dispenser is arranged to switch back to the active mode when the second sensor senses that said product has been removed.
