The main body includes an air fan that blows air into the medicine tank through an air duct of the medicine tank cover, and a medicine tank cover detection unit that detects whether or not the air duct of the medicine tank cover is adjacent to the main body so as to detect whether or not the tank unit is mounted on the main body.

Abstract: A flow of breathable gas is delivered to a subject through a patient interface assembly. An enhanced technique for determining whether the airway of subject is disengaged from the patient interface assembly. A model that provides predicted values of a dynamic property of the flow of breathable gas is fit to measured values of the dynamic property. The model and/or the fit of the predicted values to the measured values are then analyzed to determine whether or not the airway of the subject is disengaged from the patient interface assembly. This provide enhanced determination of these conditions even in implementations in which a restrictive patient interface assembly is used.

Abstract: An aerosol-generating system may include an electrical power supply, an electrical heater connected to the electrical power supply, and a substrate container. The substrate container may define a blind cavity containing an aerosol-forming substrate in the form of a gel that is a solid at room temperature.
