An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.

This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit having a storing part to store the liquid, the atomization unit being configured to generate an aerosol by atomizing the liquid; and a temperature control part configured to control the temperature of the liquid at a given location between the accommodating part (cartridge) and the storing part.

An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

Systems and methods for cleaning transmission surfaces for optical and sensor surfaces in order to maintain optimal performance under a variety of weather and environmental conditions using synthetic jet actuators. The actuators can emit a jet of water or air depending on environmental conditions and the waveform, frequency, amplitude of the actuator can be adjusted based on particle characteristics and transmission signal quality in order to better clean the surfaces.

An ultrasonic stepping motor device for generating ultra-fine single droplet includes a valve housing, a valve core, and a spring. The valve core and the spring are installed inside the valve housing, and the valve core abuts against a liquid inlet of the valve housing under an elastic force of the spring. The valve housing is connected with a injector through a catheter, and the catheter is driven for linear operation by the inverse piezoelectric effect of piezoelectric ceramics through an ultrasonic linear motor. A right end of the catheter is equipped with a rubber piston, and the rubber piston is arranged in a cavity of the injector and matched with the injector. Since the piezoelectric vibrator driven catheter can produce nano feed length, and the volume of droplets overflowed each time can reach micron level, which can meet the requirements of producing micro droplets.

When the unit dose capsule is engaged to the distal end of the elongate horn, the nozzle is disposed in an outwardly facing orientation, and the reservoir is in liquid communication with the at least one nozzle. The unit dose capsule can be included in a kit with a handheld misting device comprising a housing having a dispensing window arranged and configured to contain a sonic generator and a power source.

The present invention relates to a device (10) for supplying a mist of liquid (F). The device (10) is used in combination with a container (20) with an opening (200) for containing the liquid (F). The device (10) includes a main body (100) comprising: (i) a center axis (C); (ii) a liquid chamber (110) formed inside the main body (100), into which a predetermined amount of liquid (F) can be taken up; (iii) a first port (112) formed in a base wall (114) of the main body (100) forming a bottom surface (116) of the liquid chamber (110) so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; (iv) a second port (118) formed in the base wall (114) at a position different from the position where the first port (112) is formed so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; and (v) an aperture (120) connected to the liquid chamber (110), through which a mist of liquid (F) can be released to the outside of the main body (100). The device (10) further includes: a connecting section (122) provided on the main body (100) so as to extend from it in a direction away from the base wall (114) and used for connecting the container (20) to the main body (100); an atomizing element (124) interposed between the liquid chamber (110) and the aperture (120) to atomize the liquid (F) taken up in the liquid chamber (110) and release a mist of the liquid (F) to the outside of the main body (100) from the aperture (120); a first valve (126) mounted on the main body (100) corresponding to the first port (112), wherein the first valve (126) permits the liquid (F) in the container (20) flowing into the liquid chamber (110) through the first port (112) under the influence of gravity, and prevents the liquid (F) in the liquid chamber (110) flowing into the container (20) under the influence of gravity; and a second valve (128) mounted on the main body (100) corresponding to the second port (118), wherein the second valve (128) prevents the liquid (F) in the container (20) from flowing into the liquid chamber (110) through the second port (118) under the influence of gravity, and selectively permits or prevents the liquid (F) in the liquid cha
