A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a control member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the control member from or near a side of the faucet head.

A shower head 10, 10 comprises one or more droplet formation chambers 50, each chamber being supplied with water and pressurised air which divides the water into droplets suspended in the airflow. In one aspect, the geometric parameters of the droplet formation chamber are selected to maintain a balance between primary and secondary droplet formation modes wherein a proportion of the primary droplets formed within the chamber are stripped out of the airflow by impact with the chamber walls and re-entrained as secondary droplets formed by thin film disintegration. In another aspect, the air inlet 40 into the droplet formation chamber is provided with guide surfaces 45 which maintain a parallel axial airflow through the chamber.

A portable heated mist inhaler has a body, a supply tank of liquid, an atomizer for atomizing the liquid, and a thermostatically controlled heated nozzle. The supply tank feeds liquid to the atomizer. The atomizer creates a stream of mist from the liquid and entrained surrounding air. The mist is heated inside the nozzle so that it will be comfortable for the user. The portable heated mist inhaler has a battery which powers the atomizer and the heated nozzle.

An apparatus (10) for generating nanobubbles for use with fluid dispensing fittings is described. The apparatus includes a longitudinal shaft having a first end portion (12), a body (16) and a second end portion (14). The first end portion (12) and the second end portion (14) are adapted for connection with the body (16). The first end portion (12) and the second end portion (14) each includes a conical-shaped guide wherein the body comprises airfoil-shaped projecting members (19) arranged circumferentially on the outer circumferential surface of the body (16).

This disclosure relates to nozzles, in particular bath and shower wands that may be hand held and which generate microbubbles from water saturated with air. The bath and shower wands comprise an elongate body comprising an inlet, an elongate outlet and internal flow constriction that can generate micro bubbles from water passing through the wand.

A water pressure boosting device includes an elongated, hollow body having a body wall positioned along a longitudinal plane of the elongated body to define a first chamber and a second chamber. The body wall includes a channel connecting the first chamber and the second chamber. The first chamber includes an inlet at a first end, an outlet at a second end, a passageway spanning between the inlet and the outlet, and a water turbine positioned within the passageway, in which the water turbine spins when a fluid flow passes through the passageway. The second chamber includes an air opening on the elongated body and an air turbine. The air turbine is positioned within the second chamber and rotatable about an axis, and the air turbine spins with the water turbine.

A fire-hose nozzle includes a cylindrical housing having an inlet, an outlet and a water passageway therebetween. Centrally disposed within the passageway is an elongated, rocket-shaped stem having a larger-diameter end near the inlet and a pointed, tapered end near the outlet. Proximal the inlet are circumferentially disposed apertures for injecting ambient air into incoming water to widen the spray pattern through the outlet. Attached to the inlet is a pistol-grip controller for coupling with a conventional fire hose. Therefore, when water is delivered to the housing, the stem disrupts and separates the water stream to decrease hose back pressure, recoil and oscillation.

A foam generating device for a high-pressure water gun has a supporting body (14) defining part of a conduit (2), which extends along an axis (3) and has a mixing chamber (7) communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve (17) which is fitted around one end of the supporting body (14), is axially fixed, is rotatable and is provided with an end portion carrying a nozzle (40); such a nozzle (40) defines the outlet (5) of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve (44) which is coupled to the first sleeve (17) in a fixed axial position and in a rotatable manner and is provided with cams (49) to adjust the nozzle (40) in response to a rotation of the second sleeve (44) with respect to the first sleeve (41).

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.
