CA 2415371

A liquid sprayer (20) is provided. This liquid sprayer includes a bottle (22) having an opening and a sprayer housing attached to the bottle. This sprayer housing includes an electrical motor (26), a voltage source for powering the electrical motor, a pump driven by the motor, a switch (40) for completing an electrical circuit, a nozzle mechanism attached to the sprayer housing for spraying a liquid. The liquid sprayer also includes a deformable "pinched tube" mechanism which prevents liquid from flowing through the nozzle when the sprayer is not being used. The sprayer housing also includes a trigger (34) movably connected to the sprayer housing for closing the switch, translating the piston (30) and creating a leak-tight seal by squeezing the "pinched tube".

L'invention concerne un vaporisateur de liquide (230), lequel comprend une bouteille (22) comportant une ouverture, ainsi qu'un logement de vaporisateur attaché à la bouteille. Ce logement comprend un moteur électrique (26), une source de tension destinée à alimenter le moteur électrique, une pompe entraînée par le moteur, un commutateur (40) servant à achever le circuit électrique, ainsi qu'un mécanisme de buse fixé sur le logement du vaporisateur aux fins de vaporisation d'un liquide. Ce vaporisateur de liquide comprend également un mécanisme de tube se pinçant et se déformant, lequel empêche le liquide de s'écouler à travers la buse, lorsque l'on n'utilise pas le vaporisateur. Le logement comporte encore une détente (34) reliée mobile au logement, aux fins de fermeture du commutateur, de transfert du piston (30) et de création d'un scellement étanche par pincement du tube se pinçant.
