A misting head system (24) configured to render a fluid (32) into a mist (36) is provided. The system (24) includes a misting head body (26) and a poppet (20). The misting head body (26) has a cylindrical chamber (28), an inlet (30) configured to pass the fluid (32) into the chamber (28), and an orifice (34) configured to pass the fluid (32) out of the chamber (28) and to render the fluid (32) into the mist (36). The poppet (20) has a cylindrical core (38) configured to force the fluid (32) to pass through a space (44) between the core (38) and an inner wall (46) of the chamber (28), a fracture band (54) coupled to the core (38), configured to center the core (38) within the chamber (28), and having a plurality of flutes (60) configured to fracture the fluid (32) as the fluid (32) passes through the space (44), and an orifice end (40) of the core possessing a plurality of symmetrically spaced slits (48) configured to further fracture the fluid (32).

An atomizing spray nozzle structure comprising a main unit, a rotor and a spray nozzle, wherein the main unit and the spray nozzle are joined by thread tightening. Inside the main unit is an accommodating space. The spray nozzle has a through channel running along the axis thereof. The accommodating space is communicative with the through channel, having a rotor inside the through channel and the accommodating space, characterized in that: an end of the rotor corresponding to the accommodating space is a tapered end, and a neck is protruded from the tapered end, the length of the rotor is longer than the through channel at all circumstances, and the end with protruded neck exposed in the accommodating space of the main unit; thereby the rotor can be easily taken out for cleaning purpose after the main unit and the spray nozzle are disassembled.

A high pressure misting nozzle is disclosed having a nozzle stem body with a fluid inlet and a first chamber in communication with the fluid inlet, a fogger nozzle attached to the nozzle stem body, the fogger nozzle having a nozzle orifice and a second chamber in communication with the nozzle orifice and the first chamber, a valve member movably located in the first chamber and movable between a closed position preventing fluid communication between the fluid inlet and the first chamber, and an open position which allows fluid communication between the fluid inlet and the first chamber, and a nozzle pin movably located in the second chamber, the nozzle pin having fluid metering notches and being freely movable between a first position in which it is displaced away from the nozzle orifice, and a second position in which it is located adjacent to the nozzle orifice, the fluid entering the second chamber urging the nozzle pin toward the second position. When the nozzle pin is in the second position, the fluid metering notches control the flow of fluid through the nozzle orifice to achieve optimum atomization of the fluid.
