AI Technical Summary
Technical Problem
In the aerosol generation device, negative pressure appears in the air pressure of the air insulation chamber, causing the flue gas to suck into the air insulation chamber, reducing the heat insulation effect.
Method used
A suction hole is provided on the connection assembly of the gas insulation layer, with the ventilation area between 0.03mm2 and 3.2mm2 to prevent negative pressure from occurring, and air is sucked from the outside when the air pressure drops.
Benefits of technology
Effectively prevent the gas insulation layer from sucking into the aerosol, maintaining good thermal insulation effect, ensuring that the gas insulation layer is closed, and preventing smoke from entering.

Abstract
The embodiment of the utility model relates to the technical field of aerosol generating devices, and particularly discloses an aerosol generating device which comprises a shell, a first tubular body, a second tubular body and a first connecting assembly, the shell is internally provided with an accommodating cavity for accommodating at least part of the aerosol generating product; the first tubular body is arranged in the shell and defines part of the boundary of the containing cavity. The second tubular body is arranged in the shell and surrounds the first tubular body, and a gas heat insulation layer is arranged between the first tubular body and the second tubular body; the first connecting assembly defines part of the boundary of the gas heat insulation layer, and the first connecting assembly comprises a first sealing piece and a first connecting piece for defining part of the boundary of the containing cavity; the first connecting assembly is provided with an air suction hole communicated with the outside and the gas heat insulation layer so that the gas heat insulation layer can be prevented from generating negative pressure or the negative pressure degree can be prevented from exceeding a threshold value. According to the embodiment of the utility model, the gas heat insulation layer can keep a good heat insulation effect.
