Abstract: Water outlet fitting, e.g. tap or shower head, producing a combined flow of gas and water, and power connector therefor An apparatus produces bubbles of pure water from a flow emitter (11) comprising an annular water outlet (13) surrounding a gas outlet (12) and operating within a defined parameter space. One or more flow emitters may be incorporated into an emitter body (10) configured as a shower head or a tap. In another aspect, an apparatus produces bubbles of water from coaxial, gas and annular water flowpaths. In another aspect, a magnetic power connector is arranged to supply electrical energy to a shower head.

Abstract: A shower head is supplied with an annular airflow which surrounds a column of water travelling through a chamber to produce a suspension of water droplets in air, the diameter and length of the chamber and the diameter of the water column are selected in combination with the fluid flow parameters to operate the shower within a defined parameter space corresponding to the non-axisymmetric Rayleigh breakup regime, where the water column remains intact and spaced apart from the chamber wall for the entire length Lc of the chamber, where the airflow perturbs the water column within the chamber causing it to disintegrate into droplets downstream of the chamber outlet, and where multiple chambers are moulded on non-parallel axes with elastomeric linings facilitating withdrawal of the mould tool.
