Title
(EN) LIQUID FOAM DISPENSING DEVICE
(FR) DISPOSITIF DE DISTRIBUTION DE MOUSSE DE LIQUIDE
Abstract
(EN) A liquid foam dispensing device creates and dispenses foam (28) from a source (20) of liquid. The device employs a mixing chamber (12) upstream of a unit of porous material (26) and an outlet (30). When activated, a single motor (68) powers a liquid pump (18) and an air pump (22). The liquid pump (18) transports liquid from a source (20) to the mixing chamber (12). The air pump (22) propels air through the mixing chamber (12) wherein the air becomes pressurized. The liquid and air mix within in the mixing chamber (12). The liquid-air mixture is propelled through the porous material (26) by the flow of air, creating foam (28) that is dispensed from the outlet (30).
(FR) L'invention porte sur un dispositif de distribution de mousse de liquide, qui crée et distribue une mousse (28) à partir d'une source (20) de liquide. Le dispositif fait intervenir une chambre de mélange (12) en amont d'une unité de matériau poreux (26) et une sortie (30). Quand il est actionné, un moteur unique (68) entraîne une pompe à liquide (18) et une pompe à air (22). La pompe à liquide (18) transporte un liquide de la source (20) à la chambre de mélange (12). La pompe à air (22) propulse de l'air à travers la chambre de mélange (12), dans laquelle l'air est mis sous pression. Le liquide et l'air se mélangent à l'intérieur de la chambre de mélange (12). Le mélange liquide-air est propulsé à travers le matériau poreux (26) par l'écoulement d'air, créant une mousse (28) qui est distribuée à partir de la sortie (30).
