℃。
By above aerosol generating device and the method for being evenly heated aerosol generation matrix, may be implemented gas
Colloidal sol occurs matrix and is heated uniformly to generate the temperature range of volatile component aerosol.
By some preferred embodiments, can further realize for overall in cylindrical body, and circumference range is 17mm
~24mm, the aerosol generation matrix that length range is 10mm~50mm are evenly heated effect.
Below with reference to two specific embodiments, the present invention is described in further detail.
Embodiment 1: compare in the temperature field that matrix occurs for the aerosol of different heating method
It is overall in cylindrical body, circumference 24mm, length 20mm that the specification of matrix, which occurs, for aerosol.In addition base occurs for aerosol
One end of matter is further connected with the cigarette holder section for aspirating and cooling down.The periphery outside that matrix occurs for aerosol is also enclosed with outside matrix
Wall material, such as: cellulosic paper.
The aerosol generating device of the present embodiment has the second hair of the needle-shaped first heating element 2 in center with surrounding sleeve-shaped
Thermal element 3.First heating element 2 occurs inside matrix 4 for being inserted into aerosol, and second heatiing element 3 is surrounded on aerosol hair
On the outside of raw matrix periphery, the package wall material for matrix not occurring with aerosol be bonded, between generated gap be used to supply
Suction airstream passes through.
