Definitions

  • This application relates to the field of heat-not-bum cigarette device technologies, and in particular, to an aerosol generation device.
  • Tobacco products (such as cigarettes and cigars) burn tobacco during use to produce tobacco smoke. Attempts are made to replace these tobacco-burning products by manufacturing products that release compounds without being burnt.

  • the material may be tobacco or other non-tobacco products, where the non-tobacco products may or may not contain nicotine.
  • a size of an inner diameter of a receiving cavity is usually slightly greater than an outer diameter of the tobacco products. As a result, the tobacco products shake after being received in the receiving cavity, which affects heat transfer with a heater.

  • the air inlet pipe 20 is also used to provide support for the lower support mechanism 60, so that the lower support mechanism 60 can be stably maintained in the main housing 10.
  • the air flow is as shown by an arrow R4 in FIG. 4 .
  • FIG. 5 shows a schematic structural diagram of a preferred embodiment of the heater 30 heating by radiating infrared rays.
  • the heater 30 includes: a tubular substrate 31, an inner space of the tubular substrate 31 forming a cavity for receiving and heating the aerosol-forming article A; an infrared emission coating 32, formed on an outer surface of the tubular substrate 31, configured to radiate infrared rays to the aerosol-forming article A received in the tubular substrate 31, thereby heating the aerosol-forming article A; and an electrode coating 33, formed on the infrared emission coating 32 and conducting electricity with the infrared emission coating 32, and then connected to the positive pole/negative pole of the electric core by ways of welding pins, conductive rings and the like to supply power to the infrared emission coating 32.
  • the tubular substrate 31 is made of materials with excellent infrared transmission, such as quartz, glass, silicon carbide, ceramics, or mica.
  • the infrared emission coating 32 is preferably composed of oxides of at least one metal element, such as Mg, Al, Ti, Zr, Mn, Fe, Co, Ni, Cu, Cr, and Zn. These metal oxides can radiate far-infrared rays with heating effect when heated to an appropriate temperature.
  • a coating thickness may preferably be controlled between 30 ⁇ m to 50 ⁇ m.
  • the electrode coating 33 is made of a metal or alloy with low resistivity, such as silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or the above metal alloy materials.
  • the lower support mechanism 60 includes: an annular protrusion 61 extending into the heater 30, and an annular port 62 formed between the annular protrusion 61 and an outer wall of the lower support mechanism 60.
  • the aerosol-forming article A abuts against the annular protrusion 61 to provide a stop for the aerosol-forming article A.
  • the lower end of the heater 30 is inserted into the port 62 to be fixed.
  • the upper support mechanism 50 includes: a rigid support member 51 and a flexible support member 52, constructed into an annular shape, where the rigid support member 51 is usually made of hard plastic materials, such as PEEK, and an inner wall thereof is provided with several long and thin strip protrusions 511 arranged in a spaced manner along the circumferential direction thereof around the aerosol-forming article A of the cavity.
  • the long and thin strip protrusions 511 are designed to be inclined from top to bottom, so as to provide guidance for inclination during the operation in which the aerosol-forming article A passes through the rigid support member 51 when the aerosol-forming article A is received into the heater 30; and when the aerosol-forming article A is received into the cavity, the long and thin strip protrusions 511 can also clamp the aerosol-forming article A.
