  • the heating layer 102 includes at least two sub heating layers 1021, and the layer of the thermal insulation layer 101 may be provided with one or more welding points/welding holes, optionally:
  • Step 1103 passing through the layer body of the heat insulation layer, and respectively providing a positive electrode lead and a negative electrode lead at the positive electrode and the negative electrode of the sub heating layer;
  • step 1104 the heat insulating layer and the heating layer are sintered to obtain a heating unit assembly, and the positive electrode is electrically connected to the positive electrode lead and the negative electrode is electrically connected to the negative electrode lead.
  • step 1001, the step 1002, and the step 1004 are similar to the steps 901, 902, and 903 of the corresponding embodiment of FIG. 9, and details are not described herein.
  • the positive electrode lead 103 and the negative electrode lead 104 may be separately disposed at the positive electrode and the negative electrode of the sub heating layer 1021, respectively, and then subjected to subsequent sintering treatment.
  • the high temperature condition is such that the positive electrode of the sub heating layer 1021 is naturally electrically connected to the positive electrode lead 103 and the negative electrode is naturally electrically connected to the negative electrode lead 104.
  • the positive electrode lead 103 and the negative electrode lead 104 may be electrically connected in the above manner, and details are not described herein.
  • step 1103 may be performed simultaneously with step 1201 or step 1102; or, before step 1101 or step 1102 Executing; or alternatively, may be performed after step 1101 or step 1102, which is not limited herein.
  • the tubular heating part assembly 100 is provided with a thermal insulation layer 101 outside the heating layer 102. Therefore, while the heating layer 101 is heating the flue-cured tobacco branch 300, the heating unit assembly 100 can effectively block the heat radiated from the heating layer 102 from being transferred around the heating unit assembly 100, so that the flue-curing device does not need to be disposed around the heating unit assembly 100.
  • the heat insulating material realizes that the heating unit assembly 100 itself can transmit heat to the outside.

Abstract

L'invention concerne un ensemble partie chauffante (100), un produit associé à un ensemble partie chauffante (100) et un procédé de fabrication. L'ensemble partie chauffante (100) est tubulaire, et comprend une couche d'isolation thermique (101) et une couche chauffante (102) ; et l'ensemble partie chauffante (100) est utilisé pour un torréfacteur à tabac, et lorsqu'une cigarette à torréfier est insérée dans l'ensemble partie chauffante (100), la couche chauffante (102) est mise sous tension et génère de la chaleur pour chauffer la cigarette à torréfier dans la couche chauffante (102), la couche d'isolation thermique (101) empêche la chaleur dissipée par la couche chauffante (102) d'être transférée dans l'environnement de l'ensemble partie chauffante(100). L'ensemble partie chauffante (100) elle-même peut empêcher la chaleur d'être transférée vers l'extérieur.
