A fluid dispenser having an accumulator and a discharge head. The discharge head is secured to a base unit of the dispenser, which base unit includes a fluid accumulator. The discharge head has a housing displaceable relative to the base unit for actuating the dispenser. The discharge head has an inlet through which fluid travels from the fluid accumulator into the discharge head, and a discharge opening through which the fluid is delivered into the atmosphere. A swirling chamber having an inlet channel is provided between the fluid inlet and the discharge opening so that inflowing fluid is provided with a swirl which forms a spray stream when exiting the discharge opening. The swirling chamber is switched between a first and a second configuration by changing the geometry of its walls and/or the inlet channel.

A fire suppression system in an aircraft includes a first nozzle within a region to perform discharge of a fire suppression agent in a first direction within a region. The systems also includes a second nozzle within the region to perform discharge of the fire suppression agent in a second direction within the region. The discharge in the first direction by the first nozzle and the discharge in the second direction by the second nozzle generate and maintain a vortex of the fire suppression agent that occupies the region with rotational flow.

The present disclosure discloses an anti-splash water outflow device comprises a water outflow body and an internal assembly. The internal assembly comprises an inner body that is rotatable relative to the water outflow body upon being impacted by water. The inner body is disposed with at least two spiral blades, and two adjacent spiral blades of the at least two spiral blades define a spiral water passage. The water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body, and the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray shaped as a lampshade.

A water outlet structure for fine-gentle atomized particle water comprises a water inlet cavity, a first arc acceleration track, a side flushing cavity, a second arc acceleration track, and a water outlet hole. A first end of the first arc acceleration track is connected to a side wall of the water inlet cavity, a second end of the first arc acceleration track is connected to a first end of the side flushing cavity, and a second end of the side flushing cavity is connected to the second arc acceleration track. The water outlet hole is disposed on a circle center of the second arc acceleration track. The present disclosure further provides a shower and a kitchen shower comprising the water outlet structure.

A spray nozzle with posterior positioned switch includes a body (1), a shaft (2) and a pressing bar (3). The body (1) includes a plug (4) blocking off an inner channel. The plug (4) has a through hole (41) in communication with the inner channel. The pressing bar (3) is hinged on a posterior of the body (1). The shaft (2) extends outside the body (1) and is connected to the pressing bar (3). The body (1) includes a first compression spring (5) to push the shaft (2) forward to block off the through hole (41). A positioning mechanism is disposed between the body (1) and the pressing bar (3). The positioning mechanism is controlled by fingers except for thumb to stop the depressed pressing bar (3) in a case that a handle (11) of the body (1) is held in hand.

An atomizer nozzle for atomizing a fluid, in particular a liquid, including a nozzle opening, a spinning chamber and at least one delivery channel for feeding the fluid into the spinning chamber, at least one delivery channel extending into the spinning chamber via at least one inlet. The spinning chamber has a curved base which is curved away from the nozzle opening, and at least one delivery channel is oriented towards the base.

A flow divider for diverging a fluid includes a main body that includes first and second side surfaces being opposite to each other along a central axis of the main body. The first side surface has a central segment transversely intersecting the central axis, and having an inlet channel recessed toward the second side surface, a generally annular channel surrounding the central segment, recessed toward the second side surface, and spatially communicated with the inlet channel at a junction space, and an inclined segment surrounding the annular channel. A width of the annular channel decreases gradually from a start measurement to an end measurement along a rotational direction with respect to the central axis.

The invention relates to nozzle tips including a nozzle body and a tip portion, configured to minimize the accumulation of a resin on the nozzle tip as it is dispensed through the nozzle tip. The nozzle tip can contain a central flow channel and an internal portion that branches and guides the resin into multiple exiting flow channels that define tangential pathways to the outer surface of the nozzle tip. The nozzle tip can include grooves that define extended, sharply angled flow paths for the resin. Nozzle tips can have a neck portion separating a nozzle body and a tip end of the nozzle tip; here, a doughnut-shaped space located around the neck portion can be defined by the base of the nozzle, the crown of the nozzle, and the neck portion, for encouraging turbulent flow of the resin to scour the nozzle tip during dispensing.

A showerhead is provided having a housing, a perforate partition and a nozzle body. The housing has a fluid inlet and a fluid outlet. The perforate partition is provided in the housing between the inlet and the outlet and has at least one peripheral fluid passage communicating with the fluid inlet. Each peripheral fluid passage communicates at a downstream end with an inwardly extending peripheral slot, and each slot communicates at a downstream end with a mixing cavity. The nozzle body is carried by the housing downstream of the mixing cavity and has a compression port at an upstream end and an outlet port at a downstream end in fluid communication with the compression port.
