An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece, a liquid container, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the container. The mesh material is configured to vibrate when the piezoelectric material is actuated, whereby the aerosol is produced. The aerosol may be inhaled through the mouthpiece. The device also includes circuitry and a power supply for actuating the mesh assembly. The mouthpiece, the container, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the container. The mesh material has a rigidity that is sufficient to prevent oscillations of varying amplitudes during actuation of the piezoelectric material of the mesh assembly for consistently producing the aerosol.

Ultrasonic atomizer and electronic cigarette

The present invention discloses an ultrasonic atomizer and electronic cigarette. The ultrasonic atomizer includes an atomization piece and a liquid guide structure, which guides liquid onto an upper surface of the atomization piece; the liquid guide structure communicates with a liquid storage cavity; the upper surface of the atomization piece communicates with an airflow passage; and the atomization piece comprises a piezoelectric ceramic layer and an electric conductor, which drives vibration of the piezoelectric ceramic layer. No micropore needs to be provided in the atomization piece of the present invention to eject the atomized gas, thereby being free of the situation that the micropore is blocked by larger atomized gas particles, resulting in that the atomized gas cannot be ejected, and meanwhile the situation of liquid leakage of the atomizer can be better prevented.

INHALER

An inhalation device for delivering medication to a user may include a mouthpiece, a dosing chamber, and a flow channel connecting the mouthpiece to the dosing chamber.

20200023148 · 2020-01-23 · ·

A dry powder inhaler including a first chamber having an orifice for holding a dry powder and a gas, and a second chamber connected to the first chamber by at least one passageway for receiving an aerosolized form of the dry powder from the first chamber and delivering the aerosolized dry powder to a user. At least one optical sensor monitors aerosolized powder particles passing in the second chamber. A vibrator coupled to the first chamber aerosolizes the dry powder and causes the aerosolized powder to move through the at least one passageway thereby delivering the powder from the first chamber to the second chamber as an aerosolized dry powder. A vibrator control unit controls operation of the vibrator based on the amount of aerosolized powder particles passing in the second chamber and delivered to a user.
