Definitions

  • the invention relates to a heating device for tablets impregnated with active materials, to achieve their vaporization and their corresponding use as an air freshener or as an insect-killing medium.
  • the device uses as a heating medium a PTC semiconductor tablet, known by these acronyms for being positive temperature coefficient tablets, in which the resistance increases exponentially with the temperature until it reaches the previously established, not allowing more current to pass through.

Abstract

Le dispositif comprend une pastille semiconductrice (14) de type PTC pour chauffer des tablettes imprégnées de matières actives qui, en se vaporisant, sont utilisées comme agent d'amélioration de l'atmosphère ou comme composant insecticide. Le dispositif comprend un boîtier en plastique (1) ayant un orifice central (2) avec un logement (4) de positionnement de la pastille semi-conductrice (14) laquelle s'intercale entre deux électrodes (5 et 11) dotées de doigts de connexion correspondants (7 et 10) passant à travers des rainures (8 et 9) du boîtier (1). Le tout est complété avec une plaque en aluminium (16), et l'interposition d'une feuille de papier isolant (15), la plaque (16) et donc les autres composants étant fixés à l'intérieur du boîtier (1) par verrouillage à l'aide de griffes (17) appartenant à des pattes du boîtier (1).
