The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).

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 lid, for attachment to a container holding a liquid for use with a liquid spraying device, a vent duct defining a vent conduit extending through a lid body from a duct inlet end to a duct outlet end. A valve is disposed in the vent duct and is configured to permit air flow in a first direction, from the duct inlet end to the duct outlet end, while preventing liquid flow in a second direction opposite the first direction. A cap extends over the duct inlet end, the cap including a cap interior surface defining an interior air chamber, communicating with the vent conduit, and at least a first passage, communicating between the interior air chamber and a first cap inlet. A tube is coupled to the duct outlet end and has a tube outlet end fluidly communicating with an interior of the container.

An apparatus for applying an ultraviolet coating includes: a substantially vertically oriented frame; a first roll rotatably attached to the first side of the frame; a second roll rotatably attached to its second side; multiple nozzles disposed on the first side, above the first roll; a motor coupled to the second roll; an ultraviolet coating fluid reservoir disposed above, and coupled to, the nozzles, thereby providing the nozzles with the ultraviolet coating fluid; and an air compressor coupled to the nozzles, thereby providing the nozzles with compressed air. The ultraviolet coating fluid is provided to the nozzles solely via a gravity feed from the reservoir. In use, the motor causes sheet material, initially wound around the first roll, to advance up and over the frame and then wind onto the second roll, as the ultraviolet coating fluid is sprayed onto the sheet material by the nozzles.

The present disclosure provides a sprayer. The sprayer includes the spraying part. A spraying needle penetrates a first control channel and passes through a second water channel to reach a spraying end. A control block is connected with the spraying needle, the spraying needle is fitted in with an inner wall of a second control channel to block the water passing through the second control channel, meanwhile, the control block blocks an air inlet hole, and water in a water tank is separated from the atmospheric pressure. When the spraying needle is separated from the second control channel, the control block is distal to the air inlet hole, water in the water tank is communicated with atmospheric pressure, and the water reaches the spraying end through the second control channel.

A soap dispenser showerhead for releasing soap directly into the shower stream for easier soap application includes a showerhead comprising a handle portion and a head portion. A water flow channel extends through a bottom side of the handle portion up through the head portion to be released through a plurality of flow apertures. A valve is coupled within the water flow channel and has a valve control extending through the handle portion. A soap dispenser is selectively engageable within a cavity of the handle portion of the showerhead adjacent the valve. The soap dispenser has a storage compartment configured to store liquid soap and a nozzle in fluid communication with the storage compartment and the valve. The valve control regulates the flow of liquid soap into the water flow channel.

A reservoir system for use with a spray gun. The system includes a cup receptacle and a lid. The lid includes a lid body and a collar. The lid body provides a spout and a platform surrounding the spout. At least a portion of the platform forms a partial helical shape revolving about a central axis of the spout. The collar is rotatably connected to the lid body. Further, the collar includes a lid connector structure configured to connect the lid to the cup receptacle. In some embodiments, the reservoir system further includes one or more of an adaptor, a plug and a shaker core.
