A sustained duration trigger sprayer capable of dispensing at least 3 mL of product over a time period of about 3 seconds utilizing a force-to-actuate of between about 10 pounds and about 15 pounds. The trigger sprayer includes an enlarged piston bore and piston and an elongated trigger lever creating a high output fluid displacement with a 0.5 inch displacement distance. The container bottle and/or the sprayer shroud are contoured to provide a gripping area opposing the terminal end of the trigger lever wherein the gripping distance in from the gripping area to the terminal end of the trigger lever is no greater than 3.3 inches.

In the case of a sanitary outlet unit (1, 10), it is therefore provided to form throughflow channels (4) in a jet former (3) in such a manner that an outflow direction (14) predetermined by each throughflow channel (4) is oriented in a manner tilted in relation to a longitudinal housing axis (12) in two planes perpendicular to each other and/or about two directions perpendicular to each other.

A shower head to jet a mist of liquid droplets includes a shower nozzle, mist throttle holes, and mist guides. The mist throttle holes are each formed into a conical hole passing through the shower nozzle. The mist guides are each formed into a conical spiral shape and each fitted in the mist throttle holes so as to define mist flow passages each having a spiral shape.

A continuously variable nozzle system includes a nozzle body (5) with an inlet and an outlet. A conduit is defined between the inlet and the outlet by a series connection of components which includes a flow meter (10). The flow meter (10) has a chamber (83) with internal helical splines (82) that are configured to interact with a spray liquid passing through the chamber (83) and create a cyclone-like effect. A sphere (52) is located inside the chamber (83) for free movement along a circular path (106). A sensor is located outside of the chamber (83) and configured to detect motion of the sphere (52) and generate an output (9) signal in response to detected motion.

The present invention relates to a rhinovaccination system for preventing and treating hepatitis B, comprising a hepatitis B vaccine composition for administration to nasal mucosa in combination with a medical nozzle device.

Flow blurring injection utilizes a two-phase concept to generate fine sprays immediately at the interior exit, rather than a typical jet which gradually disintegrates into ligaments and then finer droplets for a conventional injector. Therefore, clean combustion is achieved with the FB injection for fuels with distinct properties without fuel preheating or hardware modification. However, in addition to the droplets, the FB injection also produces ligaments for highly viscous liquids and relatively larger droplets at spray edge, resulting in difficulty in sustaining the flame and performs incomplete combustion and higher emissions close to the combustor all. The disclosed swirl burst injector and method utilizes the advantages of FB injection and swirl atomization to further improve atomization, and overcomes the limitations of FB injection, providing a sustainable way to use both conventional and alternative fuels with improved efficiency and minimized emissions. The fine atomization of the present invention can be also used in various applications where fine sprays are needed.

A shower head to jet an air bubble-liquid mixture by mixing air bubbles into the liquid includes a shower nozzle, a flow-adjustment piece, and air introduction passages. The shower nozzle includes an air bubble mixing space. The flow-adjustment piece is arranged in the air bubble mixing space. The air introduction passages cause air to flow into the air bubble mixing space therethrough.

A liquid saving device includes a liquid guide and a vortex adaptor. The liquid guide includes a primary recess, an indentation, and a plurality of primary pores. The vortex adaptor includes at least one air inlet structure, a trench, a gap and a center through hole. The plurality of primary pores is coupled to the indentation for receiving a first liquid stream to generate a same plurality of second liquid streams at respective ends. At least part of the plurality of primary pores have different lengths. A primary pore has a shorter length if the first primary pore outputs its corresponding second liquid stream with a larger deflection, and vice versa. The trench receives both at least one secondary liquid stream and air to generate a first aerated vortex. An elevated flow of the first aerated vortex with a spray-form liquid stream to generate a second aerated vortex.

According to one embodiment, a processing system includes a chamber, a supplier, a detector, and a controller. The chamber is configured to store a processing object inside. The supplier is configured to supply a plurality of particles and a gas inside the chamber. The detector is configured to detect a state of air flow in a vicinity of the processing object. The controller is configured to control the supplier based on a detection value from the detector. The controller determines generation of a vortex based on data regarding a steady state of the air flow and the detection value from the detector, and controls the supplier to stop supply of the plurality of particles when the generation of the vortex is determined.
