Abstract:
A two media spray lance and nozzle useful for moistening at least a portion of absorbent material present in a mixer. The nozzle includes a central body with a connecting portion for connecting the nozzle to the two media spray lance for a supply of liquid and gas thereto, and an atomizing portion. The atomizing portion delivers droplets of liquid to the absorbent material present in the mixer to obtain moistened absorbent material.
Abstract:
A fluid spraying gun of the present invention includes: a tube-shape guide, on which a brush extending forward is implanted; a nozzle, which is formed of a flexible pipe member with a front end thereof as a free end, and sprays one portion of gas, which is supplied from the flow separation portion and passes through the nozzle, toward the brush from the front end thereof, while the nozzle undergoes the gyrating motion guided by the tube-shape guide; an inner nozzle, which sprays gas which has passed through a flow rate adjustment portion from a tip portion thereof; and a liquid distribution pipe, which penetrates the tube-shape guide, links an inside of the tube-shape guide with a liquid supply source, has an intermediate portion into which the inner nozzle is inserted in a state where the inner nozzle is directed toward the tube-shape guide, and draws up liquid from the liquid supply source by a negative pressure arising from spraying of gas by the inner nozzle to cause spraying of liquid on the inside of the tube-shape guide. According to the present invention, it is possible to provide a fluid spraying gun in which a liquid with an adequate flow rate can be mixed with a gas, converted into minute drops and sprayed.
Abstract:
The invention relates to a process and a device for the production of mouldings containing a layer of polyurethane in shot operation, in which a gas stream is introduced into the flow channel of the spray device in at least two positions.
Abstract:
Dispensing platforms, both manually operated and motion sensor based, are presented. Such devices incorporate two components: (i) “Flair” “bag within a bag” technology, and (ii) a OnePak™ dispensing head (normally closed outlet valve). Such platforms can be overpressure or underpressure based, and can interface with various Flair™ bottles. In exemplary systems (i) the fluid or other dispensate, and (ii) the propellant, whether a fluid, a gas, air or other, are provided in completely separated circuits, controlled separately, and only optionally mixed at final dispensing, downstream of the outlet valve. A propellant can be used for other ancillary functions, such as cleaning a spout or output channel, making foam or spray, controlling valves, pistons, pumps, making noise, etc.
Abstract:
A dispensing tube assembly includes a first component delivery tube surrounded by a second component delivery tube. The first component delivery tube provides an axial passage, and an annular passage is defined between the first component delivery tube and the second component delivery tube. A component travelling through the axial passage is diverted to enter the surrounding annular passage and mix with a second component traveling in that annular passage. The premixture formed by this mixture of components is then diverted from the annular passage into a post mix chamber and ultimately dispensed as a foam. A foam media may be employed to homogenous the premixture and create a high quality foam. The dispensing tube assembly is advantageously employed in a dispenser wherein soap and air are advanced through coaxial tubes to be mixed and create a foamed soap product.
Abstract:
Various spray devices are presented for mixing two media. A device can include a housing, a first supply line for supplying a first medium, a second supply line for supplying a second medium, and a flow channel leading to a nozzle. The first and second media, for example, a gas and a liquid, respectively, can be mixed in various ways. Following such mixing, the mixed media are guided to an outlet nozzle or bore, and ejected. Using injection molding techniques, very fine grooves can be made in an exemplary spray nozzle device, by appropriately fashioning an injection mold. By carefully controlling the size, shape and dimensions of such grooves, and the pressures at which the two media are fed to the spray nozzle device, a correct ratio of air to liquid can be precisely maintained, which is key to obtaining a desired spray or foam as to droplet size, droplet speed, and type of spray, mist or foam.
Abstract:
A foam soap generator is provided for implementation with various types of foam soap delivery systems. The foam soap generator includes converging air and liquid soap passages at a mixing chamber, where a prefoam is generated for ultimate extrusion through a porous passage member. In one embodiment of the invention, the soap and air are delivered through coaxial tubes, with the soap being introduced axially into the mixing chamber and the air being introduced radially angularly. In another embodiment, the liquid soap is drawn into an entrainment zone by high velocity air passing through the air passageway and into the mixing chamber.

Abstract:
The present invention provides a perfume spray head with leakproof feature comprising a spraying unit and an annular pad, wherein spraying unit has a holding groove with an aerator, a nozzle and a 1 flow passage, a protrudent docking stem with a locking dented ring as well as a curved anchoring trough and an air inlet, and annular pad has an anchoring hole with an anchoring pin, a docking pit, a perforated positioning hole with a positioning and locking pin, an air intake passage and a flow path connected with a liquid feeding channel, as well as a coupling bushing; Thereby, the spray head is switched into “ON status” or “OFF status” when the spraying unit is turned to the position where the flow passage in or out of alignment with the flow path so that effects in component simplification, assembly easiness and cost reduction are achieved.
