A drywall texture dispensing system includes an air gun that may be fluidly coupled to an air source. A reservoir is provided and the reservoir may contain a fluid. The reservoir is removably coupled to the air gun such that the reservoir is in fluid communication with the air gun. The reservoir has a diameter that is less than approximately thirty cm. Thus, the reservoir facilitates the air gun to dispense the fluid in a restricted area. A lid is removably coupled to the reservoir.

A particle spreader broadly comprising a hopper supported by a wheeled chassis, a rate plate, and a rate control gauge. The hopper presents a hopper discharge opening in fluid communication with a hopper chamber to permit flow of particles therefrom. The rate plate controls particle flow out of the hopper chamber and presents a plate discharge opening. The rate plate is shiftable between a closed position and a first open position in which the plate discharge opening is in at least partial registration with the hopper discharge opening. The rate control gauge is configured to engage the rate plate when the rate plate is in the first open position. The rate plate is biased toward the rate control gauge. The rate control gauge is adjustable to engage the rate plate when the rate plate is in a second open position.

An inhaler is disclosed wherein medicament in a dosing chamber is aerosolized with a vibrator piezoelectric transducer. A spacer is provided between a face of the transducer and a wall of the dosing chamber.

The present invention relates to an automatic black hair powder spray. Particularly, when a cartridge for storing black hair powder is mounted inside a housing in a closed state, the cartridge is pierced such that an external air flows therein and the black hair powder can be discharged together with the inflowing external air and, at this point, a path forming frame, which allows the external air to flow in from the upper part of a cartridge body so as to be guided toward the lower part of the cartridge body, is provided inside the cartridge so as to uniformly disperse all of the black hair powder without the black hair powder accumulating on the inner bottom surface of the cartridge, such that the black hair powder can be discharged in a state in which the black hair powder is uniformly dispersed into the air.

A handheld sprayer includes a housing, a turbine, a spray tip, and a hopper. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and configured to discharge a fluid into the air flow passage. In one embodiment a valve is positioned within the air flow passage and configured to control the airflow from the turbine to the spray tip. In another embodiment, a voltage limiting circuit is configured to control voltage to an electric motor of the turbine to control speed of the turbine. In another embodiment, an air inlet control device is configured to control the air intake of the turbine.

The invention relates to a device (10) for providing an aerosol from an aerosolizable material, the device comprising an aerosolization unit (300) through which pressure pulses of a carrier gas (60) are passed; a reservoir (100) comprising the aerosolizable material and which provides the aerosolizable material to the aerosolization unit (300) where the aerosolizable material is entrained by the carrier gas (60); a material providing valve (210) located between the reservoir (100) and the aerosolization unit (300) which opens in direction of the aerosolization unit (300) and which is opened and closed by a pressure difference between the reservoir (100) and the aerosolization unit (300) and which provides, in an open state, the aerosolizable material to the aerosolization unit (300).

The claimed subject matter relates to a device for dosing and aerosolization of aerosolizable material. The device includes a body with an aerosolization channel with a distal attachment for connecting a source of carrier gas. The carrier gas provides pressure pulses to the aerosolization channel. A proximal attachment allows the aerosolized material to move to a reservoir for receiving the aerosolizable material. The reservoir is connected to the body via the the aerosolization channel. At least part of the walls of the device are self-exciting membranes that can be put into oscillation by the pressure pulses.

A venturi cartridge regulating device for an air-particle dispensing system is provided, which is designed to be pre-assembled and installed in a chamber capable of atmospheric pressurization to regulate the required proportions of air and particle in a mixture formed upon activation by a propellant source and to direct a stream of a particle-gas mixture out of the chamber toward a targeted surface. The apparatus includes a chamber comprising a first plurality of inlet holes and a second plurality of inlet holes; and a conduit arranged at least partially within the chamber having a first opening arranged in the chamber. The first plurality of inlet holes is configured to intake a first substance, the second plurality of inlet holes is configured to intake a second substance, and a mixture of the first and second substances is created and mixture enters the conduit through the first opening.

An apparatus for applying drying powder after a spray tan may comprise a main body configured to receive pressurized air from an air source. The apparatus may include a powder reservoir attached to the main body and configured to hold drying powder. An internal channel within the main body may be configured to direct air flow from the external air source to the powder reservoir. The apparatus may have a nozzle attached to the main body and configured to deliver a mixture of air and drying powder. A trigger mechanism may be configured to control air flow through the internal channel.
