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).

A support stand for a spray gun hopper assembly includes a box that defines an interior space. The box has a bottom, a top, opposing sides, a back, and a front that is open. A cutout extends into the top from the front toward the back. The cutout is configured to insert a hopper of the spray gun hopper assembly, positioning a spray gun of the spray gun hopper assembly in the interior space. The box is configured to support the hopper in a position for a user to add a compound to the hopper, such as a gravity fed texturing material.

A medical device including an application device with a first fluid path and a container movably attached to the application device. The container and the application device have a second fluid path therethrough, the container includes an inner chamber that is intermediate proximal and distal portions of the second fluid path, the inner chamber is fluidly isolated from the proximal portion of the second fluid path at a first position of the container, and the inner chamber is fluidly coupled to the proximal and distal portions of the second fluid path at a second position of the container. The first fluid path bypasses the container and the passage of fluid through the first fluid path is separately controllable from the passage of fluid through the second fluid path.

A dispensing device for connection to a drone is provided. The dispensing device has an outer housing and an inner housing interior of the outer housing. The inner housing has an inner cavity having an entrance opening and an opposing exhaust opening. The area between the outer housing and the inner housing defines an outer cavity adapted to hold a material. The dispensing device also has a fluid access opening to provide fluid access between outer cavity and the inner cavity to allow material in the outer cavity to be transferred to the inner cavity and mixed with air to create an air and material mixture. An air accelerator is provided adjacent the inner cavity to accelerate the air and material mixture out of the dispensing device.

An aqueous product applicator that is connectable as an accessory retrofit product to a commercial or conventional home-use yard blower to convert to blower into an aqueous spraying device, the applicator including a fluid distribution head with an input port that is connectable to a source of pressurized aqueous solution, and a plurality of outlet ports designed to dispense fluid exiting the distribution head in the form of aqueous droplets. The distribution head further includes a mounting system for securing the distribution head to the mouth of the blower tube of a conventional handheld yard blower such that, during use, the aqueous droplets from the distribution head enter the jet air stream emitted by the blower for dispersion.

At the rear end, the powder cup spray gun has an injector, a powder cup and a receptacle for the powder cup. The powder inlet of the injector is connected to the receptacle. The powder cup and the receptacle are designed in such a way that the powder cup can be fitted into the receptacle. In addition, a grip with a connection for conveying air, a connection for atomising air, and a connection for metering air is provided. The connection for the conveying air and the connection for the metering air are connected to the injector via lines running in the grip.

A dispensing system includes a motor driven air pump having an air inlet and an air outlet, and a dispensing device. The dispensing device is releasably connected to the air pump. The dispensing device includes an air connector connected to the air outlet of the pump, a mixture outlet, a product inlet, and a product uptake system connected to the air connector, the mixture outlet, and the product inlet. The dispensing system includes a product container for a product to be dispensed. The product container is connected to the product inlet. The product container is integrated in the dispensing device. The product uptake system may include an ejector for sucking product from the container and/or a container air inlet for pressurizing the container.

A texture sprayer includes a main body and an inlet coupled to the main body. The inlet is configured to receive compressed air. A mixing chamber is disposed downstream of the inlet. The mixing chamber is configured to combine the compressed air with texture material to form a texture spray. A nozzle holder is coupled to the main body. The nozzle holder is movable between a first position and a second position. A first nozzle is coupled to the nozzle holder and a second nozzle is coupled to the nozzle holder. The texture sprayer is configured to discharge the texture spray along a spray axis through the first nozzle when the nozzle holder is in the first position and to discharge the texture spray along the spray axis through the second nozzle when the nozzle holder is in the second position.

A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes an airflow controller for controlling the flow of the compressed air to a nozzle of the spray gun, a pressure regulator for regulating a pressure of the compressed air flowing to the hopper, and a relief valve between the pressure regulator and the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.
