The invention relates to an ultrasonic mist inhaler (100), comprising 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 the liquid reservoir structure (2) comprises the sonication chamber (22).

A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

A volatile material atomizing device comprises a housing having a fan, a fluid outlet, a plurality of air inlets and a plurality of air outlets. The plurality of air outlets are positioned at least partially around the fluid outlet. A fluid reservoir includes a wick and containing a volatile material. The fluid reservoir is disposed within the housing. An atomizing assembly is in fluid communication with the wick and positioned in the housing. The atomizing assembly is configured to dispense the volatile material out of the fluid outlet.

The present invention achieves a decontamination effect with a proper amount of hydrogen peroxide mist supplied to a room to be decontaminated by further refining such hydrogen peroxide mist supplied to the room for dispersion/diffusion, and reducing the duration of operations such as aeration to increase efficiency of decontamination.

The decontamination system includes a mist generation means, a mist discharge port, and a mist dispersion/diffusion means. The mist generation means converts a decontamination liquid into a mist to generate a mist for decontamination. The mist discharge port is opened at an upper portion on an internal side wall surface of the room to discharge a such mist into the inside of the room. The mist dispersion/diffusion means generates sound flows by an ultrasound in the vertical direction from a plate surface of a vibration plate provided adjacent to a lower portion of the mist discharge port on the internal side wall surface of the room or adjacent to a lower portion on a side surface in a mist discharge direction. The mist is pressed by acoustic radiation pressure backward or laterally in intermittent operation or stronger/weaker operation of the system.

A nebulizer for producing an inhalable mist of droplets, comprising at least an aerosol generator, a housing having a liquid reservoir and control electronics, the aerosol generator consisting at least of a membrane, a piezo element and a substrate plate, and the control electronics comprising at least an RF generator, a controller, memory and switching elements, and an inductor. The aerosol generator forms a resonant circuit together with the inductor and the control electronics are configured to at least partly excite the aerosol generator to vibrate. The aerosol generator is configured such that aerosol droplets are producible by vibrations and the RF generator is configured to vary the amount of aerosol produced.

An acoustic force assisted painting system includes a housing, a nozzle, and at least one first transducer. The conduit is configured to receive paint from an external source. The nozzle is disposed in the housing. The nozzle has an inlet that is fluidly connected to the conduit and is configured to receive paint from the conduit. The nozzle has an outlet configured to dispense the paint. The at least one first transducer is disposed in the housing at a location downstream of the nozzle outlet in a flow direction of the paint.

A decontamination system not requiring large-scale equipment such as large-diameter ducts and anti-condensation heaters and for that reason capable of efficiently using a decontamination liquid. Long pipes can be installed for each of a plurality of rooms to be decontaminated, a decontamination liquid is not present in supply pipes as a residual dead liquid, and a proper amount of decontamination liquid can essentially be supplied for each room to cause no failure of an ultrasonic vibrator.

The decontamination system employs a decontamination mist and includes a compressed air generating means and a decontamination liquid supplying means, and each room to be decontaminated is provided with a primary mist generating means and a secondary mist generating means. The conveyance distance of a primary mist supply pipe communicating the primary mist generating means and the secondary mist generating means is longer than the conveyance distance of a decontamination liquid supply pipe communicating the decontamination liquid supplying means and the primary mist generating means.

The present disclosure provides a spray device and a cleaning apparatus. The spray device includes an atomization structure, which is configured to atomize a cleaning liquid when the cleaning liquid is sprayed to form liquid droplets, and a jet structure, which is configured to spray a gas along a determined direction to cause the gas sprayed to collide with the liquid droplets to form atomized particles. The spray device provided by the present disclosure may increase cleaning uniformity and cleaning efficiency to improve cleaning process results, and may further reduce an impact force to the to-be-cleaned surface by the liquid droplets to a certain level. Thus, the damage to a surface pattern of a wafer may be reduced.

A mist spraying hair brush with retractable bristles includes a brush body, an actuating shaft, a mist spraying assembly, and a housing containing these components. The actuating shaft has a bended portion. When the actuating shaft is rotated and the bended portion pushes the brush body, multiple bristles of the brush body extend out of the housing. The mist spraying assembly has an electric oscillation assembly and an injection portion. The injection portion communicates with the oscillation assembly, such that liquid flows to the oscillation assembly via the injection portion and is atomized into spray. Then the spray flows out of the housing. The mist spraying hair brush with retractable bristles is small in size and is convenient in storage. Moreover, the multiple bristles can retract into the housing, so the multiple bristles will not be bended when carried in a bag full of objects.

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).
