Definitions

  • the invention relates to the field of cigarette substitute, and specifically to a baked smoking set and a vacuum insulated heating assembly.
  • Publication CN 204 070 517 U discloses a baking-type atomizer with a heating assembly comprising a heating tube and an insulating tube, which are separated by a vacuum layer and attached via insulating gaskets.
  • Publication CN 105 342 014 A discloses a heating assembly for an electronic cigarette comprising an insulating tube made of two layers of glass separated by vacuum.
  • Publications CN 205 409 674 U , CN 203 873 016 U , WO 2018/054793 A1 , CN 207 136 243 U , and CN 207 461 401 U disclose further examples of electronic cigarettes with a heating assembly comprising a vacuum heat insulation.
  • Publication US 2018/0051845 A1 discloses a double tube that has a double tube structure of an inner tube and an outer tube, and holds a space between the inner tube and the outer tube in vacuum.
  • the technical problem to be solved by the invention is to provide a baked smoking set and a vacuum insulated heating assembly against the deficiencies of easy heat dissipation and complicated heat insulation structure in the prior art.
  • the heating circuit is arranged in segments, and each segment is electrically connected to a lead wire respectively, and each segment of the heating circuit is distributed axially on the tubular substrate, and/or each segment of the heating circuit is distributed circumferentially on the tubular substrate.
  • the inner tube is curly formed.
  • the dielectric layer is a glass layer.
  • the heating circuit is located on an outer side of the tubular substrate, so that the heating circuit is located in the vacuum area.
  • a baked smoking set in one preferable embodiment of the invention comprises a heating assembly 1, and the heating assembly 1 comprises an outer tube 11 and an inner tube 12.
  • the inner tube 12 comprises a tubular substrate 19, and a heating circuit 14 formed on a surface of the tubular substrate 19 as to generate heat after electrification; and an axial position of the heating circuit 14 on the inner tube 12 is within an axial interval of the vacuum area 13.
  • the heating circuit 14 on the inner tube 12 is arranged in segments, and each segment is electrically connected to a lead wire 15 respectively.
  • Each segment of the heating circuit 14 can be distributed axially on the tubular substrate 19, or can be distributed circumferentially on the tubular substrate 19, or can be distributed axially and circumferentially. After being arranged in segments, the heating circuit 14 can be heated in segments, and the heated object can be sequentially heated in segments, rather than being heated once.
  • the heating circuit 14 is printed on the tubular substrate 19, which can improve production efficiency, and reduce cost.
  • the heating circuit 14 also can be attached or welded or embedded onto the inner tube 12.
  • an outer wall surface of the inner tube 12 extending out of the outer tube 11 is provided with a lead wire 15 electrically connected to the heating circuit 14, and the external power supply can be connected to supply power to the heating circuit 14 via the lead wire 15.
  • Each segment of the heating circuit 14 can be independently connected to the power supply, so as to achieve the effect of segmented controlling heating.
  • the inner tube 12 is curly formed, and the heating circuit 14 can be curled simultaneously with the tubular substrate 19 after the heating circuit 14 is formed, so that the heating circuit 14 are located within the inner tube 12.
  • the heating circuit 14 is located on an outer side of the tubular substrate 19, so that the heating circuit 14 is located in the vacuum area 13.
  • the tubular substrate 19 can be directly manufactured to a tubular shape, and the heating circuit 14 is arranged outside the tubular substrate 19.
  • the tubular substrate 19 also can be curly formed, and the heating circuit 14 can be arranged on the tubular substrate 19 before or after curling. No matter whether the heating circuit 14 is arranged on the inner side or the outer side of the inner tube 12, the material of the tubular substrate 19 in the two solutions can be the same.
