Description

空洞の上流端は、ロッドによって区切られてもよい。空洞の下流端部は、フィルターによって区切られてもよい。空洞は、少なくとも１ミリメートルの長さを有してもよい。こうした空洞の長さは、こうした熱が、点火されたエアロゾル発生基体によって、またはエアロゾル発生装置のヒーターによって生成されるかどうかにかかわらず、空洞の上流で生成された熱のフィルターへの伝達を低減することができる。空洞は、フィルターの過度の加熱が回避されるように、熱伝達を低減する場合がある。空洞は、１ミリメートル～７ミリメートルの長さを有してもよい。好ましくは、空洞は、２ミリメートル～５ミリメートルの長さを有してもよい。なおより好ましくは、空洞は３ミリメートルの長さを有してもよい。 The upstream end of the cavity may be delimited by a rod. The downstream end of the cavity may be bounded by a filter. The cavity may have a length of at least 1 millimeter. The length of these cavities reduces the transfer of heat generated upstream of the cavity to the filter, whether such heat is generated by an ignited aerosol generating substrate or by a heater in an aerosol generator. can do. Cavities may reduce heat transfer so that excessive heating of the filter is avoided. The cavity may have a length of 1 mm to 7 mm. Preferably, the cavity may have a length of 2 mm to 5 mm. Even more preferably, the cavity may have a length of 3 millimeters.
