An aerosol delivery system includes a perforate membrane comprising a plurality of apertures, as well as a fluid reservoir reservoir in fluid communication with a first side of the perforate membrane and actuation means configured to vibrate the perforate membrane to cause a liquid in the fluid reservoir during use to be ejected as liquid droplets from a second side of the perforate membrane. The plurality of apertures comprises first and second arrays of apertures of first and second configurations which are grouped together in first and second discrete regions of the perforate membrane. The fluid reservoir includes first and second reservoir portions and a liquid barrier by which the first and second reservoir portions are separated. A removable cartridge for an aerosol delivery system.

An ultrasonic atomization sheet (1) and atomizer and an ultrasonic electronic cigarette are disclosed. The ultrasonic atomization sheet (1) comprises a flaky piezoelectric substrate (101), a surface electrode (102) attached to one surface of the piezoelectric substrate (101), and a drive electrode (103) attached to the other surface of the piezoelectric substrate (101). The piezoelectric substrate (101) is elongated. The piezoelectric substrate (101) is composed of an oscillating section (106) and a fixed section (107) connected to each other. The surface electrode (102) is fixed on one surface of the oscillating section (106), and the drive electrode (103) is fixed on the other surface of the oscillating section (106). The surface electrode (102) and the drive electrode (103) are both rectangular or circular.

A simulated three-dimensional flame apparatus, comprising a base (1), a mist generation mechanism disposed in the base (1), and an outer cover (2) and a light emitting mechanism connected to the base (1). The inner cavity of the outer cover (2) is a mist accumulation chamber (3), a mist outlet (4) of the mist generation mechanism is in communication with the mist accumulation chamber (3), or a part that generates mist in the mist generation mechanism is disposed inside of the mist accumulation chamber (3). The top of the outer cover (2) is provided with a flame outlet (5). The light emitting mechanism is disposed inside of the outer cover (2) and the light emission direction thereof is toward the flame outlet (5), such that the light beam from the light emitting mechanism radiates on the mist emitted from the flame outlet (5), and the refraction of the light beam off the mist forms a dynamic flame (6). The light beam from the light source (17) radiates on the mist which is emitted irregularly, the light refracts off the mist and forms a dynamic flame (6), thereby presenting realistically the flickering effect of a burning flame.

A humidifier includes a container for containing a fluid; a cartridge for nebulizing the fluid, the cartridge configured to be fixed inside the container, the cartridge including a cartridge housing including a bottom side that is configured to contact a bottom of the container, a top side opposite to the bottom side; a back side; a front side; a left side; and a right side; and a handle on the top side of the cartridge housing, the handle projecting upward and away from the cartridge housing.

A hookah device (202) which attaches to a hookah (246). The hookah device (202) comprises a plurality of ultrasonic mist generator devices (201) for generating a mist for inhalation by a user. The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

Provided herein is an ultrasonic-based aerosol generation device. The aerosol generation device according to some embodiments of the present disclosure includes a liquid reservoir configured to store an aerosol-forming substrate in a liquid state, a wick configured to absorb the stored aerosol-forming substrate, an ultrasonic vibrator configured to vaporize the absorbed aerosol-forming substrate through ultrasonic waves to generate an aerosol, and a controller configured to control the ultrasonic vibrator. Here, at least a portion of the wick and at least a portion of the ultrasonic vibrator may be implemented to have a flat shape and may be disposed to come in close contact with each other. In this way, a vaporization area may be maximized, and vapor production may be significantly enhanced.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.
