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.

A liquid dispensing device includes a body, a nozzle on an end of the body, a liquid container coupled to the body, and a piston configured to move in the body so as to control an ejection of liquid from the nozzle. The piston and the nozzle are configured to be detached from the body as an assembly.

An airbrush that sprays liquid in a mist form. A supply of a compressed air and a supply of the spray liquid can be controlled at the same time only using a spray button included in a spray head. Accordingly, a loss of the spray liquid can be minimized, the airbrush can be maintained clean, and usability of the airbrush can be enhanced.

A spray-gun apparatus, comprising a spray-gun handle, a spray-gun tube-body, and a connection adapter; wherein the connection adapter is connected between the spray-gun handle and the spray-gun tube-body; wherein the first conduction tube is connected with the spray-gun handle and the spray-gun tube-body to use as a gas output path, and the second conduction tube is connected with a second cover-body to use as a gas suction path. Thereby, the gas sent from the spray-gun handle is blown out through the first conduction tube of the connection adapter and the spray-gun tube-body, and the water-sucking tube set inside the spray-gun tube-body will be made to spray liquid; and the second conduction tube of the connection adapter is used to connect a gas suction apparatus, so that the gas around the second conduction tube can be sucked into through the second conduction tube of the connection adapter.

A system and method for dermal spraying includes a portable, hand-held skin care device with disposable formulation capsules that spray a formulation unto the skin. The device is set to maximize absorption and provide professional and uniform quality of application. The device receives, clamps and identifies the formulation capsules and its contents. Control circuitry regulates the formulation delivery. This assures the quantity, proportion, speed and timing of the application of the cosmetic formulation, including self-cleaning cycle operation and single button control logic. The capsule enables convenience and sterility from use of disposable capsules at home. Preferably the capsules contain a cosmetic or cosmeceutical formulation. The capsule has a sealed body having any of a variety of suitable shapes such as the general shape of a cylinder with two ends having hemispherical caps.

A nebulizer comprises a housing, a closed pressure system, at least one pressure relief mechanism and a nebulization mechanism. The housing comprises a nozzle, and the nozzle comprises an outlet portion and an inlet portion communicated with a pressurized gas source. The closed pressure system comprises at least one gas inlet and a gas outlet. The at least one pressure relief mechanism is disposed on the at least one gas inlet. The nebulization mechanism is capable of moving to a nebulization position. An interior pressure in the closed pressure system is changed by the at least one pressure relief mechanism to control the nebulization mechanism for nebulization.

A spray applicator assembly discharges distributable product from a cartridge using low air pressure. The cartridge is held captive between a piston advancing from the rear to expel contents and a nozzle snugly attached at the front to receive expelled contents and to convert the contents into droplets by subjecting the contents to an array of focused high velocity air streams. The nozzle has an open barrel design and is able to discharge a variety of liquid or viscous distributable product without readjustment, other than resetting a proportioning valve in the low pressure air feed line. An air chamber immediately in front of the cartridge nose provides constant backpressure, which dominates to cleanly stop flow of distributable product into the nozzle whenever the piston stops advancing. When the piston resumes advancement, the flow restarts cleanly. Clean stopping and starting saves distributable product from waste. Variations in the distributable product might include, without limitation, a broad variety of materials including coating materials and combustibles.

The utility model discloses an adjustable coating cleaning gun, comprising a gun body, a trigger switch and a cleaning solution storage kettle, wherein a cleaning spray head is fixed to a gun head of the gun body; a spray pipe joint is fixed to a gun head air passage of the gun body; a swinging spray pipe is arranged in the cleaning spray head; the swinging spray pipe is a hollow elliptical pipe; a long axis of a section of the hollow elliptical pipe is longitudinally arranged, and a short axis is horizontally arranged.

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.

A spray gun includes a one-piece main body, a trigger, a paint needle operating element coupled to the trigger, a paint needle coupled to the paint needle operating element, and an exchangeable spray agent guiding unit, the inlet region of which is or can be connected to a material supply device for the material to be sprayed, wherein the main body has at least one opening for receiving the exchangeable spray agent directing unit. Also disclosed is a material supply device, a cover, a method for mounting an exchangeable spray agent guiding unit in or on a spray gun having a one-piece main body, and a method for removing an exchangeable spray agent directing unit from or out of a one-piece spray gun.
