Pressurised sprayer, comprising a tank, the tank comprising a main body, a head region and a plunger for manually pressurising said tank. Pressurised sprayer also comprising a compressed air inlet for automatically pressurising the tank with air from outside, a pressure relief valve, a compressed flow outlet, and a removable, external compressor module that is independent of the tank, the compressor module for its part comprising an air compressor and a battery for supplying the air compressor with electricity, the compressor module being connected to said compressed air inlet, said compressor module being secured to the sprayer. Pressurised sprayer where said compressed air inlet comprises a valve stem, said valve stem for its part being a non-return valve, and the compressor module is connected to said valve stem via a hose having a connection head.

The subject matter discloses a faucet inserted into a paint port of a painting apparatus to control flow of paint removed from the painting apparatus, the faucet comprising an external mold rotatably insertable into a paint port of a painting apparatus; wherein said external mold is spiral; an internal mold insertable into the external mold; a faucet valve to control flow of paint from the paint apparatus.

A tank holding a quantity of liquid releasably connects to an electric pump module through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The electric pump module includes an electric pump, a switch assembly, and a check valve. The electric pump module directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

A nasal douche having a valve, container part and cap part, wherein the container part serves to receive irrigation liquid and carries cap part. The cap part has a nose attachment with an outlet opening for irrigation liquid connected fluidically to interior of container part via discharge channel, wherein nose attachment is intended to be attached to a nostril of the user. The container part or cap part is assigned a mouthpiece for controlling the valve, wherein the valve is closed in a rest position and flow of irrigation liquid out through the nose attachment is thus suppressed, and wherein the valve can be brought to an open position, under the action of respiratory air when the user blows into the mouthpiece, and irrigation liquid thus flows out through the nose attachment, wherein respiratory air or ambient air flows into the container part to allow the outward flow.

A system for micro spray backpacks is a reusable device which has at least one cartridge that contains at least one agrochemical element or another type of concentrate which is to be dispensed separately from the dilution, performing this task at the very moment at which its application is required. The device contemplates the adjustment in the concentration of the mix, as well as the change of the cartridges without spilling the solvent contained in the tank of the backpack. The cartridge prevents oxidation of the concentrate which is to be applied due to its being isolated, reducing economic and environmental costs. The device is designed for use in agricultural and industrial sectors.

A fluid dispenser includes a bottle having an opening, a fluid dispensing tube inside the bottle, an inner cap having a top surface having first and second openings separated from each other, a lower cylindrical post extending from the top surface and being coupleable to the opening of the bottle, and an upper cylindrical post extending from the top surface and in an opposite direction relative to the lower cylindrical post; and a cap connector detachably coupled to the upper cylindrical post, the cap connector expanding and contracting between an expansion position and a contraction position and providing an extension path of the fluid dispensing tube in the bottle.

A power sprayer is disclosed herein. The power sprayer includes a support frame configured to mount to a back of a user, a liquid reservoir affixed to the support frame, and a fluid distribution wand hydraulically coupled to the liquid reservoir and configured to distribute the volume of liquid from the liquid reservoir. The power sprayer may further include a compressed air assembly affixed to the support frame. The compressed air assembly may include a compressed air tank and a pressure regulator. The compressed air assembly may be pneumatically coupled with the liquid reservoir and configured to internally pressurize a volume of liquid in the liquid reservoir with compressed air from the compressed air tank and via the pressure regulator and a plurality of valves. The power sprayer may be configured for autonomous mobility independent of an air compressor.

A hand-held laundry treating apparatus includes a portable body for storing wash water and contaminated water, supplying wash water according to positive pressure air supplied into the portable body, collecting contaminated water generated during washing of a laundry item using negative pressure air created during generation of the positive pressure air, and washing a localized portion of the laundry item while being in contact with the laundry item placed on a vertical plane or a horizontal plane, and a water tank separately mounted at the portable body for storing wash water to be supplied when washing the localized portion of the laundry item placed on the vertical plane or the horizontal plane and contaminated water generated after washing of the laundry item.

The disclosure includes a system comprising a first chamber having pressurized gas, a compressor connected to the first chamber (which may be a bladder), and a second chamber connected to the first chamber. The second chamber includes contents. The system also includes an exit from the second chamber. The pressurized gas from the first chamber travels into the second chamber to force the contents out of the exit of the second chamber. The compressor increases the pressure of the gas in the first chamber.

The present lid and sprayer provides a safe and labor-saving means to pressurize the interior of a pressure vessel through the use of a valve stem. The valve stem extends from the top of the lid, aligned with the cylindrical axis of the lid and protected from damaging impact. The valve stem may be protected by the gripping portion of the lid and may be protected by other enclosing structures within the lid. The user partially fills the pressure vessel, and attached the present lid. Then, the air chuck of a compressor is attached to the valve stem to pressurize the pressure vessel. Thus, the user may spray a liquid from the sprayer without the need for manual pumping.
