Patent

CA 2439801

An apparatus periodically dispenses an air freshening substance from a pressurized container into a room. A device is provided to sense when the room is occupied, such as by detecting the light level in the room. The air freshening substance is dispensed more frequently when the room is being used than at other times. However, the dispensing continues even when the room is unoccupied to treat odors arising from objects permanently located in the room.

L'invention concerne un appareil distribuant, de manière périodique, une substance désodorisante, depuis un contenant pressurisé, dans une pièce. Un dispositif permet de détecter lorsque la pièce est occupée, par exemple, par la détection du niveau de lumière de la pièce. La substance désodorisante est distribuée plus fréquemment lorsque la pièce est utilisée que lorsqu'elle est inoccupée. Cependant, la distribution continue même lorsque la pièce n'est pas occupée, afin de traiter les odeurs émanant des objets se trouvant en permanence dans ladite pièce.
