Title

(EN) FLUID DISPENSER WITH ONE-WAY VALVE, AIR-INLET MECHANISM, AND INTEGRATED FLUID LEVEL SENSOR

(FR) DISTRIBUTEUR DE FLUIDE AVEC VALVE UNIDIRECTIONNELLE, MÉCANISME D'ENTRÉE D'AIR ET CAPTEUR DE NIVEAU DE FLUIDE INTÉGRÉ

Abstract

(EN) A fluid dispenser for hygienic and efficient delivery of liquids such as soap, sanitizer, or lotion is disclosed. The dispenser comprises a reservoir having an upper and lower portion, the lower portion being coupled to a dispensing mechanism incorporating a one-way valve configured to allow liquid discharge while preventing backflow and contamination. An actuator, operable manually or automatically, activates the dispensing mechanism to release the liquid through an outlet nozzle. To prevent vacuum formation within the reservoir, an air inlet mechanism is provided at the upper portion to allow entry of filtered ambient air, thereby equalizing internal pressure. The air inlet mechanism includes a filtration assembly comprising a prefilter and a HEPA filter to maintain fluid purity. A sensor unit positioned within the dispenser monitors the fluid level, facilitating accurate detection and timely refilling.

(FR) L'invention concerne un distributeur de fluide pour l'administration hygiénique et efficace de liquides tels que du savon, un désinfectant ou une lotion. Le distributeur comprend un réservoir ayant une partie supérieure et une partie inférieure, la partie inférieure étant accouplée à un mécanisme de distribution incorporant une valve unidirectionnelle conçue pour permettre une évacuation de liquide tout en empêchant un reflux et une contamination. Un actionneur, actionnable manuellement ou automatiquement, active le mécanisme de distribution pour libérer le liquide à travers une buse de sortie. Pour empêcher la formation de vide à l'intérieur du réservoir, un mécanisme d'entrée d'air est disposé au niveau de la partie supérieure pour permettre l'entrée d'air ambiant filtré, ce qui permet d'égaliser la pression interne. Le mécanisme d'entrée d'air comprend un ensemble de filtration comprenant un préfiltre et un filtre HEPA pour maintenir la pureté du fluide. Une unité de capteur positionnée à l'intérieur du distributeur surveille le niveau de fluide, facilitant une détection précise et un remplissage en temps opportun.
