CA 2227419

A device for dispensing a volatile substance includes a gas-fueled, portable heat source. The heat source has a combustion nozzle capable of supporting a flame. The device includes a sole plate for heating the volatile substance and heat transfer device for enclosing the combustion nozzle and transferring heat from the flame to the sole plate. A heat box substantially surrounds the heat transfer device and sole plate. The heat box has a window (44) through which volatile substances released from the sole plate may escape. The device also has a housing (46) within which the heat box is held in spaced relation from the housing, the housing (46) having a housing window (52) adjacent to the heat box window (44). By use of the device, a flame at the combusion nozzle heats the sole plate to volatilize a volatile substance placed thereon, which may then escape into the atmosphere through the heat box window, with the housing remaining cool. Operation of the device may be controlled by control buttons (64, 66).

Dispositif de distribution d'une substance volatile, comportant une source de chaleur portative alimentée au gaz. La source de chaleur comporte un bec de combustion capable de soutenir une flamme. Le dispositif comporte une plaque de sole pour le chauffage de la substance volatile et un dispositif de transfert de chaleur permettant d'enfermer le bec de combustion et de transférer la chaleur depuis la flamme sur la plaque de sole. Une boîte de chauffage entoure sensiblement le dispositif de transfert de chaleur et la plaque de sole. La boîte est munie d'une ouverture (44) par laquelle les substances volatiles dégagées de la plaque de sole peuvent s'échapper. Le dispositif comporte également un boîtier (46) dans lequel est placée la boîte de chauffage, avec un espacement par rapport au boîtier, le boîtier (46) présentant une ouverture (52) à proximité de l'ouverture de la boîte de chauffage (44). Au moyen du dispositif, une flamme produite au niveau du bec de combustion chauffe la plaque de sole de façon à volatiliser une substance volatile placée sur elle, qui peut ensuite s'échapper dans l'atmosphère à travers l'ouverture de la boîte de chauffage, le boîtier demeurant froid. Le fonctionnement du dispositif peut être commandé par des boutons de commande (64, 66).
