Patent

CA 2196666

An electrical device is disclosed for evaporating active substances. It comprises a housing in which is arranged an electrical heating device and into which a receptacle containing the active substance can be inserted. The device also has a heat exchanger which is in thermal contact with the heating device and located at a point where the active substance evaporates. A connecting plug is provided on the housing for connection to an electrical socket and has a first rotating connection unit which engages with a second rotating connection unit in the housing. Contacts are provided in each of the rotating connection units and can be connected to or disconnected from the associated opposing contacts in the other rotating connection unit. According to the invention, the contacts and associated opposing contacts are arranged on the two rotating connection units in such a way that a continuous electrical connection is created between the connecting plug contacts and the heating device in each of two possible positions separated by 90~, and an angle range is created between the two with a switching position in which the connection is opened.

L'invention concerne un dispositif électronique d'évaporation de substances actives, comportant un boîtier dans lequel est placé un dispositif de chauffage électrique et dans lequel peut être inséré un récipient contenant la substance active. Ce dispositif comprend en outre un échangeur de chaleur en contact thermique avec le dispositif de chauffage, disposé à l'endroit où la substance active doit s'évaporer. Une prise mâle de raccordement à une prise murale est montée sur le boîtier. Cette prise présente un premier élément d'accouplement rotatif, en contact avec un second élément d'accouplement rotatif situé dans le boîtier. Des contacts permettant d'établir ou de couper le contact avec les contre-contacts correspondants de l'autre élément d'accouplement rotatif respectif sont disposés dans chacun des éléments d'accouplement rotatif. Les contacts et les contre-contacts correspondants sont disposés sur les deux éléments d'accouplement rotatif de façon à produire, dans deux positions décalées de 90~, un raccord électrique continu entre les contacts de la prise de raccordement et le dispositif de chauffage et de façon à créer, entre les deux, une zone angulaire avec une position de commutation dans laquelle le raccord est ouvert.
