A method of assembling a nozzle assembly is disclosed. The method includes: providing a nozzle member having a central passage defined by at least an inner side surface and an inner distal surface; inserting a fluid atomizer into the central passage of the nozzle member; and, with a distal surface of the fluid atomizer arranged adjacent the inner distal surface of the nozzle member, flexing legs of the fluid atomizer in a radially-outward direction for engaging each leg of the legs with the inner side surface of the nozzle member. A fluid atomizer is also disclosed. A nozzle assembly is also disclosed. A method of utilizing a nozzle assembly is also disclosed.

A nozzle body and a method of forming the nozzle body. The nozzle body includes at least two hollow-cone nozzle geometries. The nozzle body includes an injection molded or a 3D printed thermoplastic material.

A method for producing a nozzle body and a nozzle body. The method includes at least partially processing a nozzle body blank produced by one of an injection molding process or a 3D printing process by laser processing to form the nozzle body. The nozzle body includes a frusto-conical section; at least one nozzle bore having a diameter of less than or equal to 300 μm coupling the frusto-conical section to an outside of the nozzle body; and at least one turbulence channel that is configured to communicate with the frusto-conical section and to taper in a direction toward to the frusto-conical section

The present disclosure relates to an anti-splash water outlet structure. A water path core is provided in a water outlet body, a first water path is formed in the water path core, and a second water path is formed between the outer sidewalls of the water path core and the inner sidewalls of the water outlet body. The water outlet of the second water path surrounds the the water outlet of the first water path, and the water curtain flowing out of the second water path surrounds the water outlet of the first water path. The technical scheme of the present disclosure can avoid the splash of the water column while ensuring the water output of the kitchen faucet and the shower. It has the advantages of simple structure, low cost and good anti-splash effect.

A spray nozzle assembly includes a rotating spray nozzle and a cap for attachment to a squeeze bottle. The spray nozzle includes at least one exit orifice and at least three sidewall portions. The cap includes an indicator on an upper surface.

A spray head adapted for connection to a supply of fluid. The head includes a body to receive the supply of fluid and a number of conical mixing volumes, in fluid connection with the body and supply of fluid, each conical mixing volume having an outlet. Each conical mixing volume includes at least one first inlet for a flow of fluid into the conical mixing volume at an angle to a conical axis thereof, and at least one second inlet for a flow of fluid into the conical mixing volume substantially parallel to the conical axis. There is a valve disposed upstream of the conical mixing volumes, the valve adapted to divide and vary the supply of fluid flow between the at least one first inlet and the at least one second inlet, which in turn varies the output of the fluid from the outlet of the conical mixing volumes.

The invention relates to a fluid spray nozzle which is intended to be mounted on a distribution receptacle, the nozzle comprising at least one fluid inlet capillary extending longitudinally along an axis, a supply means to receive the fluid from the at least one inlet capillary in order to supply it to a pillar comprising at least two pipes, the pipes extending longitudinally along the axis A1 and being radially offset relative to the axis, at least two turbulence channels in fluid connection with the at least two pipes, a turbulence chamber for receiving the fluid coming tangentially from the at least two turbulence channels in order to supply at least one spray opening having axial symmetry and a constant cross-section s, the chamber having a cross-section decreasing towards the opening and having a maximum cross-section S and a maximum diameter, the ratio of the cross-section s of the spray opening to the maximum cross-section S of the turbulence chamber is 1%≤s/S≤20%.

VALVE CARTRIDGE FOR ACTUATORS OF A RANGE OF PACKAGING, having an independent complementary valve mechanism (1) to be mounted directly on the internal region of an outlet nozzle (2) of a known actuator (3) of a usual packaging (4), which actuator is traditionally combined with a pump-type mechanism (5) for extracting the product (P) contained in said packaging (4) and, accordingly, said packaging has a seal-tight upper closing part (6) that forms the body housing the extractor pump-type mechanism (5), the upper part of which is in communication with the outlet nozzle (2), while the lower part is in communication with the inside of the packaging (4), where it produces a vacuum, negative pressure or positive pressure, sufficient to move the product (P) to the outlet nozzle (2), containing an inlet duct (7) and an outlet duct (8), and in the latter there is mounted the independent complementary valve mechanism (1) which alters said stream of the semi-solid product (P) turning it into a drip, trickle or spray.

The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

The ejection head includes a pressing member; a nozzle tip that is fitted to a concavity; and an insert member. The insert member includes: a concave portion that forms a filling space for the content medium; at least one through hole formed on a circumferential wall; and a long groove that extends from the through hole to the nozzle tip. The insert member has a front end having an outer circumferential edge formed as an annular inclined surface, and the front end is formed with a bulging portion. The bulging portion is formed with a plurality of radial grooves and a cylindrical groove. At least one through hole is located in a position that is circumferentially offset from the plurality of radial grooves.
