A gyrating nozzle spray gun includes a grip including an air inlet, a valve seat, a gas-delivery tube connected to the valve seat and terminating in a mating connection portion and a trigger operable for letting external compressed air go into the air inlet and the gas-delivery tube, an attachment tube connected to the mating connection portion of the gas-delivery tube, and a gyrating pattern generator including a gas-supply tube connected to the mating connection portion and suspended in an accommodation chamber, a bearing mounted on a connecting portion, a coupling socket mounted on an outer race and a gyrating nozzle fastened to the coupling socket and rotatably disposed in an orifice and defining a gas accumulation chamber and an oblique jet hole for ejection of the intake flow of compressed air that goes through the air inlet, the gas-delivery tube and the gas-supply tube into the gas accumulation chamber.

An unheated, essential oil diffuser relies on a pressurized air stream to educt oil from a reservoir, followed by separators including separation chambers and an annular channel. The latter is a long channel having an aspect ratio (L/d) of from about 10 to about 120, for length L and thickness d. Thickness d is effective diameter, also known as hydraulic diameter (4 times c.s. area, divided by wetted or exposed perimeter), and may be from about 25 to about 100 thousandths of an inch (0.6 to 2.5 mm) across the thin passage, with a target range of from about 55 to 75 mils (0.7 to 1 mm). This geometry provides laminar flow at Reynolds number values less than a few hundred for virtually its complete distance of from under one inch (25 mm) to over three inches (76 mm).

A gyrating nozzle head spray gun includes grip including air inlet, valve seat, gas-delivery tube connected to valve seat and terminating in mating connection screw rod and trigger operable for letting external compressed air go into air inlet and gas-delivery tube, attachment tube connected to mating connection screw rod of the gas-delivery tube, gyrating nozzle head assembly including gas-supply tube connected to mating connection screw rod and suspended in attachment tube, bearing, cap, linking module and gyrating nozzle head mounted on one end of the gas-supply tube, and water-delivery tube having one end extended bottom of coupling hole of gas-delivery tube and connected to water tank for sucking in water and opposite end thereof inserted through gyrating nozzle head for ejecting fluid for creating mist of fine droplets upon ejection of compressed air through the gas-supply tube and oblique jet hole and central axle hole of the gyrating nozzle head.

A nebulizer includes a housing having a chamber for holding an aerosol, an air outlet communicating with the chamber for permitting the aerosol to be withdrawn from the chamber, and a reservoir for holding a liquid to be aerosolized. The nebulizer also includes a liquid orifice located in the chamber, one or more liquid channels defined between the reservoir and the liquid orifice, the one or more liquid channels having a liquid volume, and a pressurized gas outlet located in the chamber adjacent to the liquid orifice. A baffle is located in the chamber and positioned relative to the pressurized gas outlet and the liquid outlet so as to divert pressurized gas from the pressurized gas outlet and over the liquid orifice. The baffle has a diverter surface area. The liquid volume is at least 80 mm.sup.3. The diverter surface area is less than 5.0 mm.sup.2.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

Disinfecting method for disinfecting a room or a surface, comprising the steps of: a) providing a fluid comprising at least one organic compound obtainable from natural substances, wherein the organic compound is provided in an non-polar or polar medium, or in a mixture of non-polar and polar media; b) mixing the fluid with a gas such that fluid particles are suspended in the gas, and an aerosol of fluid particles is formed; c) directing a flow of the aerosol formed in step b) on said surface or into said room.

An improved structure of gyrating nozzle spray gun includes a grip including an air inlet and a trigger-controlled valve seat, a gas delivery tube connected to the valve seat, and a gyrating nozzle head including a connection nut threaded onto a front tubular mating connection screw rod of the gas delivery tube, an end cap threaded onto outer thread of the connection nut, a bearing positioned in the end cap, and a rotator mounted in the bearing and rotatable with an inner race of the bearing and defining therein a gas accumulation chamber for receiving compressed air from the valve seat via the gas delivery tube and the connection nut and an oblique jet hole eccentrically located in the front wall thereof for ejecting compressed air and causing the rotator to rotate during ejection of compressed air.

A spray apparatus having built-in air regulation and a swivel connection to an air supply and uses thereof are described herein.

The invention relates to a method and a device for generating a nanoaerosol, wherein at least one fluid to be atomized is atomized in a nozzle via a nozzle opening of the nozzle along a discharge direction in the form of fluid particles, the atomized fluid particles are deflected from the discharge direction and larger fluid particles are at least partially separated from smaller fluid particles, the separated larger fluid particles are returned to the fluid to be atomized and the smaller fluid particles are dispensed onto the environment. A cartridge in which the nozzle and the fluid to be atomized are arranged is used. According to the invention, a stream of a carrier gas is generated in the nozzle and at least one fluid to be atomized is brought into contact with the carrier gas.
