A recently granted patent (Publication Number: US11903536B2) discloses an automatic liquid soap supplying mechanism designed specifically for aircraft lavatory units. The mechanism includes a dispenser body with a vertically long shape storing liquid soap and a nozzle for dispensing the soap. The system is equipped with a bracket attached to the wall of the lavatory unit, holding the dispenser body vertically with the nozzle positioned above the washbasin. An actuator with a vertically moving member and a motor is activated by a human body detection unit to dispense soap when a hand is detected near the nozzle. The actuator and bracket are separate elements attached to the wall and indirectly connected only via the aircraft lavatory wall, ensuring efficient and hygienic soap dispensing.

Furthermore, the mechanism features a bracket with lower and upper portions supporting the dispenser body to prevent movement in various directions. The connecting member between the vertically moving member and the nozzle includes a flexible portion, allowing for easy movement and dispensing of soap. This flexible portion is located inside the storage portion of the lavatory unit, ensuring a compact and functional design. The patent highlights the innovative approach to automatic soap dispensing in aircraft lavatories, focusing on user convenience and hygiene maintenance during air travel.
