The first fixing seat 50, the second fixing seat 60 and the heating pipe 80 are sleeved in the hollow area 41 of the heat insulation member 40, and the heat insulation space 44 is formed in the heat insulation member 40, so that heat generated by the heating pipe 80 is not easily transferred out through the heat insulation member 40, and the heat generated by the heating pipe 80 is effectively prevented from being transferred to the shell of the aerosol generating device 100, so that the shell is overheated.

In some embodiments, the insulation space 44 may be insulated by forming the insulation space 44 in a negative pressure state, that is, by drawing air out of the insulation space 44 so that the gas pressure of the insulation space 44 is lower than the external gas pressure, or in some embodiments, the insulation space 44 may be filled with an inert gas which has a low thermal conductivity, is stable in properties, and is easy to obtain, so that the insulation may be performed by filling the inert gas, for example, the inert gas satisfying these conditions may be any one of argon, krypton, and xenon.

Because the hollow area 41 of the heat insulation member 40 is sleeved with the first fixing seat 50 and the second fixing seat 60, the fastening member 45 can be arranged on the inner wall 43 of the heat insulation member 40, and the first fixing seat 50 and the second fixing seat 60 are respectively provided with a matching portion adapted to the fastening member 45, so that the first fixing seat 50 and the second fixing seat 60 are respectively and independently fixedly connected with the heat insulation member 40 in a clamping manner, and further the first fixing seat 50 and the second fixing seat 60 can independently apply extrusion force required for sealing to the sealing member 70, so that the sealing member 70 reliably provides sealing between the first fixing seat 50 and the first end portion of the heating pipe 80 and between the second fixing seat 60 and the second end portion of the heating pipe 80.

It is easy to understand that the material of the heating tube 80 is made of a high thermal conductive material, so as to conduct the heat generated by the heating element to the inside of the heating tube 80 with high efficiency. For example, the high thermal conductivity material may be a metal or ceramic material, and the ceramic material may be one of an oxide, nitride, carbide, boride, etc., although other high thermal conductivity polymer materials may be used to form the heating tube 80.

In some embodiments, the heating element may be a resistance heating element, such as a metal heating mesh, which is attached to the outer wall of the heating tube 80, and is electrically energized to generate heat, and then the heat is transferred to the inside of the heating tube 80 through the heating tube 80.
