  • the flat first receiving chamber 26 extends the area available for heating, on the one hand reducing the diameter of the heating zone, so that more space is available for thermal insulation and insulation, while also reducing the outer dimensions of the tobacco evaporator It is convenient to carry, and solves the technical problem that the size and volume of the tobacco evaporator in the prior art are large, and the tobacco heating is insufficient and uneven, causing tobacco waste and affecting the mouthfeel.
  • the heating member 30 is not disposed on the bottom wall 210 of the lower cover recess 21, but is tight.
  • the fixing member 30 is attached to the wall surface 11 of the opening of the upper cover 10 facing the recess 21.
  • the heating member 30 can be disposed between the second insulating cotton 62 and the wall surface 11 of the upper cover 10, and is closely attached to the wall surface 11
  • the diameter of the heating zone can also be reduced, and the tobacco sheet 4 in the first accommodation space 26 is sufficiently uniformly heated.

Abstract

La présente invention concerne un évaporateur de tabac et son procédé de commande de chauffage de tabac. L'évaporateur de tabac comprend un boîtier (1). Le boîtier (1) comprend un couvercle supérieur (10), un couvercle inférieur (20) et un élément chauffant (30). Une partie concave (21) avec une ouverture tournée vers le couvercle supérieur (10) est agencée sur le couvercle inférieur (20). Le couvercle supérieur (10) recouvre l'ouverture de la partie concave (21) afin de former une première cavité de réception (26) qui est utilisée de façon à recevoir un flocon de tabac (4) et qui est pourvue d'une section transversale plate. L'élément chauffant (30) est étroitement attaché et fixé à la surface (11) de paroi du couvercle supérieur (10), tout contre l'ouverture de la partie concave du couvercle inférieur ou la paroi inférieure (210) de la partie concave (21) est située sur la surface de la partie extérieure de la première cavité de réception (26). Par conséquent, le flocon de tabac peut être étalé à plat dans la première cavité de réception, de sorte que la quantité de tabac sur la zone de chauffage d'unité soit réduite et que le tabac puisse être plus complètement et uniformément chauffé; la première cavité de réception plate peut être utilisée afin d'étendre la région de chauffage et le diamètre de la région de chauffage est réduit, de sorte que davantage d'espace puisse être utilisé aux fins d'isolation thermique et de conservation de la chaleur, que la taille apparente de l'évaporateur de tabac soit réduite, que l'évaporateur de tabac soit commode à transporter et que le problème technique dans l'état de la technique, selon lequel la taille et le volume de l'évaporateur de tabac sont importants et ainsi les déchets de tabac sont provoqués par un chauffage de tabac insuffisant et non uniforme, soit résolu.
