A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

The invention provides for an spray nozzle apparatus (1) for a spray drying apparatus comprising a nozzle provided with at least one nozzle orifice (26) for outputting spray droplets of a product to be dried and a least one inlet orifice (24) for transferring said product into a nozzle chamber (22), including an apparatus for adjusting the size of outputted droplets inline during the spray drying process.

A discharge head (30) of a liquid dispenser (10), comprising a pump device or pressure accumulator, is known for selectively discharging liquid, on the one hand, in the form of an atomized spray jet and, on the other hand, in the form of a non-atomized liquid stream or in the form of individual droplets. The discharge head (30) is provided for fastening to a base unit (20) of the liquid dispenser (10), said base unit comprising a liquid reservoir (22). The discharge head has a housing (32) which is configured for the stationary or linearly movable or linearly and rotatably movable fastening to the base unit (20) of the liquid dispenser (10). The discharge head (30) has a liquid outlet (34) through which liquid may be discharged from the liquid reservoir (22) into a surrounding atmosphere, and a liquid inlet (38) through which liquid may be conducted out of the liquid reservoir (22) to the liquid outlet (34).

It is proposed that the liquid outlet (34) has an outlet channel (36) penetrating the housing. An internal part (50) is arranged inside the outlet channel (36), a spray opening (56) at the end of a spray duct (54) being provided on the front face (52) of said internal part facing in the direction of the surrounding atmosphere. The internal part (50) and the outlet channel (36) are displaceable relative to one another so that in a first relative position a bypass duct (64) is produced between an internal wall of the outlet channel (36) and an outer face of the internal part (50), the flow resistance thereof being lower than that of the spray duct (54), and in a second relative position this bypass duct (64) is at least partially closed so that the flow resistance of the bypass duct (64) is greater than that of the spray duct (54).

The present invention relates to micro fogging device and method which can spray micro fog-like fine water droplet to be used, for example, for protected cultivation, such as green houses, or barns. The micro fogging device can supply fog tinier than the conventional low pressure foggers, and includes: a low pressure fogger unit for forming fog at low pressure; and a venture nozzle which is coupled to a coupling pipe of the low pressure fogger unit to finely segment/divide the water droplets supplied from the low pressure fogger unit, thereby minimizing usage of water and compressed air and maximizing the effectiveness of fog generation.

The embodiments of this application relate to an intelligent sanitary product field, in particular to a sprinkler and an intelligent toilet. The sprinkler includes a sprinkling mechanism, an adjusting mechanism and a water supply mechanism. The sprinkling mechanism is set with a mixing chamber, a first water distribution chamber and a second water distribution chamber. The adjusting mechanism includes a water outlet seat and an adjusting cap where the adjusting cap with a water hole can be placed on the water outlet seat in a movable way and the water outlet seat is set with a first water outlet trough and a second water outlet trough for connecting to the first water distribution chamber and the second water distribution chamber respectively. The water supply mechanism is set on the adjustment cap on the side away from the water outlet seat.

A nozzle arrangement connected to a source of pressurized fluid mat produces a series of fast pulsed discharges of fluid in quick succession wherein the nozzle arrangement comprises a nozzle body with an inlet for the pressurized fluid into a chamber with a downstream wall with an outlet hole in said chamber wall wherein a prodder moves between a sealed and unsealed position in said outlet hole of the chamber wall and wherein a sprung plunger that is upstream of and connected to said prodder and has a annular seal that forms a seal between said plunger and the chamber creating a mobile chamber wall upstream of the downstream wall in said chamber, simultaneously moves between a downstream and an upstream position as the chamber fills with the fluid and then returns to a downstream position as the prodder returns from an unsealed position to a sealed position while the fluid is discharged.

A spray nozzle having a nozzle housing, at least one swirl chamber which is disposed in the nozzle housing, and at least one exit opening, wherein the exit opening is disposed at the end of an exit duct which emanates from the swirl chamber and widens in the direction towards the exit opening, wherein a constriction is disposed at the transition from the swirl chamber to the exit duct, and wherein the angle of the wall steadily increases in the direction towards the exit opening or in portions remains identical, in which an angle of the wall of the exit duct at the exit opening, when viewed in the circumferential direction of the exit opening, is not constant.

A swirler for swirling fluid in a nozzle has a swirler body. The swirler body defines an inlet end, an outlet end opposed to the inlet end, and a circumferential periphery. The circumferential periphery extends axially from the inlet end to the outlet end. The outlet end defines a first swirl chamber. The inlet end defines a second swirl chamber.
