An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece located at one of opposite longitudinal ends of the device; a liquid container; a transducer that, when actuated, causes a liquid from the container to be aerosolized such that the aerosol may be inhaled from the device by a person through the mouthpiece; and circuitry and a power supply for actuating the transducer. The mouthpiece, the container, and the transducer are located in-line along a longitudinal axis of a housing of the device extending between the opposite longitudinal ends of the device. The container is located between and separates the transducer and the mouthpiece. The container and the transducer are contained within a cartridge that is insertable into and removable from the housing of the device. The container and the transducer are replaceable by the person when the liquid in the container is depleted.

The invention relates to an ultrasonic mist inhaler (100), comprising: —a mouthpiece (1) for inhaling the mist, —a liquid reservoir structure (2) comprising a liquid chamber (21) adapted to receive liquid to be atomized, —a sonication chamber (22) in fluid communication with the liquid chamber (21), wherein at least part of the liquid reservoir structure (2) and the mouthpiece (1) form the sonication chamber (22).

An aerosol-generating device includes a pump. The pump includes a first pump chamber and a second pump chamber on opposing sides of a separation element. Each of the first pump chamber and the second pump chamber have an inlet valve and an outlet valve configured to establish a pumping direction. The pump also includes a first actuator and a second actuator. The first actuator is associated with the first pump chamber and the second actuator is associated with the second pump chamber. The first actuator and the second actuator are each configured to change a chamber volume of the respective pump chamber. The pump further includes a common inlet, and a common outlet. The common inlet and common outlet are in fluid communication with the first pump chamber and the second pump chamber and are configured to establish a flow direction. The pumping direction is aligned with the flow direction.

A dry burning detection method, applied to a vaporizer, includes: obtaining vaporization parameters of a vaporization piece in real time, and calculating a variance between the vaporization parameters and a sample mean, the sample mean being a value representing a vaporization parameter level of a stable vaporization stage of the vaporizer; and determining that the vaporization piece is dry-burned if the variance is greater than a preset variance value corresponding to the vaporization parameter, the preset variance value being used for distinguishing a vaporization parameter fluctuation caused by vaporization dry burning and a vaporization parameter fluctuation caused by non-vaporization dry burning.

A mist inhaler device (200) for generating a mist for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).
