An atomizer for an electronic cigarette and an electronic cigarette are presented. The atomizer comprises a substrate, a heating device and a cover member. The substrate is provided with a mounting space. One end of the heating device is inserted into the mounting space and partially extends to the outside through the substrate to form a controlling member, and the other end is exposed to the outer surface of the substrate. When the controlling member is pressed into the substrate by an external pressing force, the heating device is pushed to move toward the outside of the substrate along the mounting space and partially extends out of the substrate. The cover member is detachably mounted to the substrate and covers the controlling member. The technical solution of the present invention is convenient for the user to disassemble and replace the heating device inside the atomizer, effectively saving the use cost.

The invention relates to an aerosol-generating device. The aerosol-generating device comprises a first housing portion and a second housing portion. The first housing portion comprises a cavity for receiving an aerosol-generating article comprising aerosol-forming substrate. The first housing portion and second housing portion are configured arrangeable in a first position, in which the first housing portion is extended relative to the second housing position, and in which the cavity is accessible for insertion of the aerosol-generating article. The first housing portion and second housing portion are configured arrangeable in a second position, in which the second housing portion is retracted at least partly within the cavity.

A method of generating aerosol from aerosol generating material using an aerosol provision device is disclosed. The method comprises supplying power to a heating element to begin heating the aerosol generating material to an operational temperature (e.g. a temperature at which aerosol is generated). After a first predetermined time period, the method provides a signal to a user to signify that the user may begin inhaling on the device. After a second predetermined time period or after a user has stopped inhaling, the method reduces the supply of power to the heating element. In this way a user can be guided as to when to inhale on a device. The timing may be adjusted to suit a particular delivery and/or device. Also described are aerosol provision devices and systems.
