The aerosol-generating means 1 comprises an electric heater for heating the aerosol-generating article 3.

As an example of the electrically actuated smoking device, the aerosol-generating article 3 comprises a plug of an aerosol-forming substrate such as a cigarette plug, and when the aerosol-generating article 3 is inserted into the aerosol-generating means 1, The heater accommodated in the aerosol-generating means 1 is inserted into the aerosol-generating substrate.

However, in such a type of smoking device, the electric heater is in direct contact with the aerosol-generating substrate and, therefore, may be contaminated with material from the aerosol-forming substrate during use, thereby reducing the heat transfer efficiency and deodorizing by carbonization. Causes the problem to occur.

Therefore, there is a need to frequently clean the electric heater inside the apparatus, but there is a problem that it is not easy to clean the heater installed in the narrow space inside the apparatus. Therefore, when it is difficult to wash, the entire apparatus needs to be discarded.

In addition, it may be difficult to remove the aerosol-generating article 3 from the aerosol-generating means 1 after smoking due to such contamination of the heater.

Therefore, the development of a technology that can solve the above problems is required.
