A spray device (A) according to the present disclosure includes: a two-fluid nozzle (11) which sprays a mist (91); a spray-device-side gas flow path (12) for supplying a gas to the two-fluid nozzle (11); a gas supply source (17) which supplies the gas to the spray-device-side gas flow path (12); a spray-device-side liquid flow path (13) for supplying a liquid to the two-fluid nozzle (11); a liquid supply source (18) which supplies the liquid to the spray-device-side liquid flow path (13); a pulse-driven liquid flow control valve (14) having a valve opening degree that is adjusted according to a pulse signal to control the flow rate of the liquid in the spray-device-side liquid flow path (13); and a controller (30) which adjusts, in multiple levels, the concentration of the mist (91) sprayed from the two-fluid nozzle 11 by adjusting the valve opening degree of the liquid flow control valve 14.

The present invention discloses a water mist nano gasification conversion device, including a main body (1), an electronic high-voltage generator (5), a water inlet (3), a water supply tank (4), an electronic water mist spraying device (6) arranged in the water supply tank (4), and an atomization tube (2) arranged above the water supply tank (4). Water droplets and water mist sprayed by the electronic water mist spraying device (6) by using a negative electric field are blown into an electric field region which is arranged in the atomization tube (2) for ionization and decomposition. The nanoscale water mist generated by the device has the advantages of sterilizing and humidifying the air, improving air cleanliness and achieving skin moisturization.

An ultrasonic humidifier may include a water tank, an atomizer arranged in the water tank, an upper cover detachably connected with the water tank and an artificial flower, wherein the upper cover is provided with a mist outlet pipeline, and a branch of the artificial flower is inserted from the mist outlet pipeline; and a user can change different varieties and styles of artificial flowers according to current mood. Different colors and styles of artificial flowers have different impacts on visual sense every time, which is not easy to generate visual fatigue. Moreover, mist is directly sprayed from the branch of the artificial flower, and the artificial flower becomes beautiful and elegant visually. When aromatic oil matched with the artificial flower is added into water, smell sense and visual sense of the user are capable of being perfectly unified.

Disclosed is a mist maker featuring forced airflow to reduce moisture condensation and/or featuring airflow drifting, including: a hollow water-proof housing, a base, a atomizer, and an air blowing device, the base being disposed at the hollow water-proof housing, an accommodation space for accommodating an essential oil water solution, the atomizer being configured to atomize the essential oil water solution to form a mist; the air blowing device produces a forced airflow to push the mist; in further conjunction with a miniaturized landscape zone, a special profile is created; the forced airflow produced by the air blowing device is discharged radially via the air vents in the hollow water-proof housing, thereby carrying the mist overflowing out of the flow zone farther away to avoid mist accumulation around the mist maker and thus avoids water accumulation caused by mist condensation.

A plurality of air-releasing openings with inclined sidewalls are arranged at the periphery of the water tank of an aroma diffuser product, each air-release opening disposed in a position that is set at a certain angle along the inclined direction of the sidewalls. The certain angle being formed by the center longitudinal axis of the exit side of the opening relative to the radius of the water tank. A plurality of mist-releasing openings is arranged non-horizontally at the upper part of the water tank or the periphery of the water tank cover. An aroma diffuser or ultrasonic atomizer configured with the plurality of air-releasing openings and/or the plurality of mist-releasing openings.

A deposition apparatus supplies mist containing fine particles to a substrate and forms a film including the fine particles on a substrate surface, and includes an air guide member that covers at least a portion of the substrate surface, and a mist supplying section that supplies mist to a space between the substrate surface and the air guide member. The mist supplying section includes a charge applying section, which applies a positive or negative charge to the mist, and a mist ejecting section, which ejects the mist charged by the mist applying section into the space. The air guide member has a wall surface facing the substrate surface, and the deposition apparatus includes an electrostatic field generating section that causes a potential having a same sign as the mist charged by the charge applying section to be generated by the wall surface.

Provided is a mist generator including: a container that stores a liquid; a gas supply unit that supplies a gas into the container; and an electrode that generates plasma of the gas between the electrode and the liquid, where the supply direction of the gas fed from the gas supply opening of the gas supply unit is different from a direction in which gravity acts.

Provided is a mist device capable of suppressing a decrease in amount of mist generated to be retained in a retaining space. A mist device 1 of the present invention includes a mist generation unit 8 that generates mist from stored water, and a mist supply unit 10 that supplies the mist generated by the mist generation unit to a retaining part that forms a retaining space having an upper part opened, the mist device is configured so that the mist supplied from the mist supply unit is retained in a retaining space 4, and the mist generation unit 8 includes a mist supply flow rate decrease suppression part 40 that suppresses a decrease in amount of mist generated.

Provided herein are an ultrasonic-based aerosol generation device with a new structure capable of reducing cartridge replacement costs and a control method thereof. The ultrasonic-based aerosol generation device according to some embodiments of the present disclosure may include a replaceable cartridge which is configured to store a liquid aerosol-forming substrate and a control main body which is configured to be coupled to the cartridge. Also, the control main body may include a controller and a vibration member which is configured to generate ultrasonic vibrations to vaporize the aerosol-forming substrate stored in the cartridge. Here, the controller may monitor a temperature of the vibration member and controls operation of the vibration member on the basis of a monitoring result.

Provided herein is an ultrasonic-based aerosol generation device capable of ensuring immediate aerosol generation according to puffs and reducing cartridge replacement costs. The ultrasonic-based aerosol generation device according to some embodiments of the present disclosure may include a control main body which includes a vibration member configured to generate ultrasonic vibrations and a cartridge which is replaceable and coupled to the control main body. In this structure, since the vibration member, which is a relatively expensive component, is disposed at the control main body side, the cartridge replacement costs may be significantly reduced. Further, since a vibration transmission member configured to transmit the ultrasonic vibrations of the vibration member to a liquid aerosol-forming substrate is disposed in the cartridge, an aerosol may be smoothly generated.
