A container structure for a floating type humidifier according to the present disclosure, in which the floating type humidifier is installed to be movable in a state in which the floating type humidifier floats on water stored in an accommodating space, includes: a lower body which has therein the accommodating space opened at an upper side thereof, and has a lower surface that is horizontally formed and seated on an installation surface; and an upper body which has a lower end that is correspondingly coupled to an upper end of the lower body, and an upper end that is formed to be bent toward the accommodating space so as to have a curved surface, and allows water flowing in a lateral direction by external force to flow back into the accommodating space.

The invention relates to an ultrasonic mist inhaler, comprising: a liquid reservoir structure comprising a liquid chamber adapted to receive liquid to be atomized, a sonication chamber in fluid communication with the liquid chamber,
wherein the sonication chamber comprises means of ultrasonic vibrations receiving a predetermined signal for vibrating the means of ultrasonic vibrations in a range comprised between 2.8 MHz and 3.2 MHz as depicted in FIG. 3.

An ultrasonic droplet delivery device and related methods for delivering precise and repeatable amounts of a substance to a user for respiratory use is disclosed. The ultrasonic droplet delivery device generally comprises a body housing, a mouthpiece having an ejector mechanism, and a fluid cartridge having at least one fluid reservoir. In certain embodiments, the ejector mechanism may comprise at least one ultrasonic actuator and at least one aperture plate with a plurality of openings formed through its thickness for ejecting droplets. The device may further comprise at least one differential pressure sensor configured to activate the ejector mechanism upon sensing a pre-determined pressure change within the device to thereby generate the ejected stream of droplets.

Various aspects of the present disclosure are directed to an electronic cigarette with improved aerosol delivery characteristics. For example, an electronic cigarette consistent with the present disclosure may include a wick capable of enhanced delivery of electronic cigarette juice to a heating element. In particular, the wick may be a stainless-steel, wire mesh. In some specific embodiments, the wick may be coated to improve its electrically insulative characteristics.

An ultrasonic atomizer including a shell, a sealing cover, a base, a through pipe, an outer connecting ring, an inner connecting ring, an outer loudspeaker cover, a butt-joint pipe, an inner loudspeaker cover and an atomization mechanism, wherein the through pipe is arranged on the shell, the outer connecting ring is arranged at a corresponding position of the through pipe, the inner connecting ring is arranged inside the through pipe, the outer loudspeaker cover is arranged inside the shell, and an end portion of the outer loudspeaker cover penetrates out of the sealing cover and extends outside so as to be connected with the base, the butt-joint pipe is arranged inside the through pipe, the inner loudspeaker cover is connected with an end portion of the butt-joint pipe, and the atomization mechanism is arranged inside the base.

An ultrasonic electronic cigarette atomizer is disclosed, including an atomization core, an atomizer housing, and a liquid bin. When liquid is filled into the liquid bin, the liquid passing hole is closed and the air outlet channel is closed, to avoid leakage or immersion of liquid, the atomizer is clean and sanitary, waste is avoided, and cost is saved. The whole operation is very simple, the atomization core is convenient to replace, hands are not stained with liquid, and the liquid is convenient to fill. The cigarette liquid is unlikely to flow out through the liquid filling hole, and large granular cigarette liquid generated in atomization can be recycled.

A fluid dispensing cartridge includes a housing body having a proximal end wall, a distal end wall, a fluid chamber, and a hollow throat portion. The fluid chamber is in fluid communication with the hollow throat portion. The proximal end wall provides a proximal termination of the fluid chamber and the distal end wall provides a distal termination of the hollow throat portion. A plurality of electrical contacts face proximally from the proximal end wall. The fluid dispensing cartridge includes a fluid jetting chip that has a plurality of fluid jetting nozzles.

The present disclosure generally relates to the field of aerosol generation devices, and more particularly to electronic cigarettes configured to generation of aerosols from aqueous formulations of nicotine or cannabis products. The present disclosure further provides aqueous cannabinoid compositions for use in the aerosol generation devices.
