Disclosed are an inclined ultrasonic atomizing sheet structure, an atomizer and an electronic cigarette. The inclined ultrasonic atomizing sheet structure comprises atomization cotton and an ultrasonic atomizing sheet. The ultrasonic atomizing sheet is obliquely arranged relative to the horizontal plane, and two ends of the atomization cotton are used for connecting to tobacco tar in a tobacco tar cavity via tobacco tar guide cotton, or the two ends of the atomization cotton are directly arranged in the tobacco tar cavity. A lower surface of the atomization cotton is in contact with an atomization surface of the ultrasonic atomizing sheet. The ultrasonic atomizing sheet structure can prevent the ultrasonic atomizing sheet from being soaked in the tobacco tar and thus prevent the situation that smoke cannot be produced by atomization.

Systems and methods are provided for aerosolizing and delivering therapeutic substances in an electronic aerosol delivery device with airflow regulation. Calibrated airflow resistance settings enable adjustment and control of flow velocity and or flow volume of air, aerosolized air, and or entrained aerosol particles, through the device, for optimal aerosol delivery among diverse conditions and applications.

An ultrasonic vaporization assembly includes: a piezoelectric drive element provided with a first through hole; a vaporizer plate stacked with the piezoelectric drive element, the vaporizer plate having a microporous zone at a position corresponding to the first through hole; and a loading board arranged on a side surface of the vaporizer plate which faces away from the piezoelectric drive element, the loading board being provided with a second through hole at a position corresponding to the microporous zone. A ratio of a pore size of the second through hole to a diameter of the microporous zone is greater than or equal to 0.75 and less than or equal to 1.5.

A microporous vaporization assembly includes: a microporous vaporization plate for vaporizing an aerosol-generation substrate to generate aerosols; and a circuit board flexibly electrically connected to the microporous vaporization plate, the circuit board transmitting an electrical signal of the circuit board to the microporous vaporization plate. In an embodiment, the microporous vaporization assembly includes a flexible electrical conductor between the circuit board and the microporous vaporization plate. The flexible electrical conductor is in contact with the circuit board and the microporous vaporization plate respectively, to implement a flexible electrical connection between the circuit board and the microporous vaporization plate.

A microporous vaporization assembly includes: a piezoceramic plate, a through hole being provided in the piezoceramic plate; and a vaporization plate including a body part and a fence part, the body part being stacked on and bonded to the piezoceramic plate and covering the through hole, a plurality of vaporization holes being provided in an area of the body part corresponding to the through hole. The fence part is arranged protruding from a surface of the body part stacked with the piezoceramic plate and surrounds an outer circumference of the piezoceramic plate.

A pulmonary delivery system includes an elongated body having an openable and closeable portion thereof for receiving an insertable and replaceable container such as a cartridge of pure medical product disposed in a saline solution. The medical product may be epinephrine, insulin or nicotine disposed in a saline solution. The system also incorporates a penetrating element that is disposed in the cylinder to pierce the cartridge and release the nicotine solution into the cylinder and into or on a micron mesh grid. A flow of air created by inhaling through a mouthpiece draws air into an individual's lungs from an entrainment port and onto a grid for atomizing a mist of micron droplets through the grid. It is recognized that the air from the entrainment port further dilutes the concentration of the medical product. The grid is connected to a source of electrical power to vibrate the mesh grid.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.
