The main body comprises at least one center air delivery passage and at least one liquid-handling passage. The inseparable nozzle defines a liquid-emitting orifice that is in fluid communication with the at least on liquid-handling passage of the main body, and defines a center air orifice that is in fluid communication with the at least on center air delivery passage of the main body.

A fuel cell nozzle includes a fuel circuit receiver configured to receive a fuel circuit and an air circuit. At least a portion of the air circuit is integrally formed with the fuel circuit receiver. The nozzle can further include a base portion that is configured to interface with a fuel cell. The fuel circuit receiver and the air circuit can extend from the base portion.

Infectious diseases may be acquired in public areas such as transportation terminals, shopping centers, schools, hospitals, restaurants and hotels. Large surface areas may be disinfected using a spray system to distribute a suitable fluid such as a disinfectant. Many existing spray systems are large and unwieldy causing operator fatigue. Some spray systems have large, heavy external tanks that provide fluid to the spray system using an external fluid hose. Disclosed is an improved portable spraying system that may be carried by a system operator. The improved system has a tank, a pump, a valve, a nozzle, and a fan all powered by a battery. The tank, the pump, and the battery are arranged to minimize operator fatigue. With the valve set to the priming position, fluid recirculates to prime the pump. Once the pump is primed, the valve is turned to the spray position to begin spraying.

A low-frequency ultrasonic atomizing device includes a piezoelectric vibrator, a horn, a secondary atomizing chamber, a gas-liquid valve end cover, a Laval-type valve core, a stepped valve core, and a gas-liquid valve body. The piezoelectric vibrator is glued onto the horn, and the gas-liquid valve end cap is connected to the gas-liquid valve body by a thread, while both the stepped valve core and the Laval-type valve core are installed within a cylindrical cavity of the valve body, an end of the Laval-type valve core being sleeved at an end of the stepped valve core. The horn and the secondary atomizing chamber, the secondary atomizing chamber and the gas-liquid valve end cover are connected by a double-head stud and a nut. The device achieves multi-stage atomization of droplets, which increases the atomization quantity of a spray device, the droplets being small, and also achieves long distance spraying.

A cathode material integrated processing device, which dries, applies, and heat-treats a cathode material, according to an embodiment of the invention includes a support frame, a chamber part including a cylindrical body configured to accommodate the cathode material and a thick plate coupled to each of both ends of the cylindrical body to seal both the ends of the cylindrical body and configured to fix the cylindrical body to an upper portion of the support frame, a heating part disposed in close proximity to each of the outside the cylindrical body and the outside the thick plate of the chamber part to heat the chamber part, a spray part including one or more nozzles, which is disposed between an upper portion and one side of the cylindrical body of the chamber part and is inserted in a longitudinal direction of the cylindrical body to spray a coating liquid to the cathode material within the chamber part through a gas, a stirring part rotatably disposed inside the cylindrical body of the chamber part to stir the cathode material within the chamber part, a driving part connected to one side of the stirring part and rotatably disposed at one side of an upper portion of the support frame to rotate the stirring part, and a control part configured to control the heating part, the spray part, and the driving part.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

The disclosure concerns a spray bottle assembly for use with an atomized-spray dispensing device. The spray bottle assembly generally includes a bottle containing an amount of cosmetic composition, a release mechanism having a port associated therewith, an insert with an insert lumen configured to engage the port for communicating the cosmetic composition therethrough, a nozzle for configuring a stream of the cosmetic composition expelled from the spray bottle assembly, a mixing chamber for mixing compressed air with the stream of the cosmetic composition, and a spray aperture for communicating atomized spray. The spray bottle assembly is designed for use with equipment having corresponding release elements for engaging the insert and release mechanism of the bottle.

A spray gun includes first and second air outlet channel arrangements. At least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the first arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the second arrangement can be controlled independently of one another in an open and/or closed loop manner. The spray gun also includes a third air outlet channel arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the third arrangement can be controlled in an open and/or closed loop manner independently of at least one parameter of the first arrangement, and/or independently of at least one parameter of the second arrangement. Thus, three different types of air (atomisation, shaping, and transporting) can each be controlled independently providing increased flexibility in use for different painting tasks.
