The water-saving nozzle has an outer housing that includes an outer vortex screw in operative engagement with an inner housing that is disposed inside the outer housing. The vortex screw has helical threads. The inner housing has an inner vortex screw with outside helical threads. When water passes through the outer and inner vortex screws the water is rotated before the water passes into the vortex chambers of the inner and outer housings. The water discharged from the outer housing forms an outer dome shape and the water discharged from the inner housing forms an inner dome shape inside the outer dome shape.

A multifunctional sprinkler device concealed in a ceiling for simultaneously removing smoke and toxic gas is disclosed. The multifunctional sprinkler device concealed in a ceiling for simultaneously removing smoke and toxic gas, in the event of a fire, suctions and removes surrounding smoke and toxic gas while spraying water and at the same time, prevents suffocation by lowering a lethal dose of the toxic gas to be lower than or equal to a safe range within a short time, and provides lighting even in the event of a fire and power outage to guide rapid evacuation.

The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.

The present disclosure discloses a swing structure and a corresponding water outlet device. A water passing chamber in a body of the swing structure is equipped with a swing member, and an upper end of the swing member is provided with a recess facing a water inlet hole of the water passing chamber. The water flow impacts the recess to drive the swing member to swing to one side randomly. After a lower end of the swing member is out of range of a water outlet hole of the water passing chamber, the upper and lower ends of the swing member are adjacent to or abut against a wall of the water passing chamber, so that the swing member can swing back and forth.

A liquid spraying system having an electrically operated pulse width modulation control for directing a modulated liquid discharge based upon frequency and duty cycle of a reciprocally operated liquid control valve. The spray nozzle assembly includes a nozzle body having an inwardly converging conical chamber communicating between an upstream liquid directing plate and a downstream liquid discharge passage. The liquid directing plate is formed with a one or more rings of circumferentially spaced liquid directing passages angularly oriented with respect to a central liquid flow axis of the nozzle body for directing liquid discharging from said nozzle body discharge passage into a predetermined conical spray pattern.

A thermostatically wrapped press-type photosensitive spray shower includes a fixing base; a handheld shower; a pair of side arms whose two opposite sides are provided with a plurality of spray nozzles at intervals. A water conduit system including a main conduit and two first branches. Two water conduit branches being provided between two ends of each of two first branches, one of the two water conduit branches is equipped with a manual pressing valve, the other one of the two water conduit branches is equipped with a solenoid valve, a touch switch of the solenoid valves is assembled on a pressing panel of manual pressing valve. The pair of side arms can spray comprehensively by cooperating with a handheld shower. A mechanical pressing and touch dual-mode switch of a water outlet mechanism is provided.

An aerosol hairspray product for styling and/or shaping hair wherein the product comprises: a container; a spraying device; a propellant; a hairstyling formulation comprising: (a) at least about 50% water; and (b) from about 0.01% to about 20% of a hairstyling polymer, wherein the hairstyling polymer is selected from the group consisting of: acrylates copolymers of two or more monomers of (meth)acrylic acid or one of their simple esters; acrylates/hydroxyesters acrylates copolymers of butyl acrylate, methyl methacrylate, methacrylic acid, ethyl acrylate and hydroxyethyl methacrylate; polyurethane-14/AMP-acrylates polymer blend; and mixtures thereof. The product comprises about 2% or less alcohol, or is substantially free of alcohol, and the product comprises 54% or less VOC.

The present invention relates to a cleaning apparatus comprising steam having an induced cyclonic rotation emanating from a tapered nozzle. Specifically, the present invention comprises an element within a tube near or otherwise adjacent to a tapered nozzle from which steam emanates. As the steam passes the element, a rotation is induced in the steam causing it to rotate upon exiting the tapered nozzle. The induced cyclonic rotation of the steam exiting the tapered nozzle of a cleaning apparatus aids in the cleaning of objects. In an exemplary embodiment, the steam cleaning apparatus is a jewelry cleaning apparatus.

A nozzle includes a shell, a distributor, a panel and a collar. The distributor is inserted in the shell. The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.
