Abstract: An impeller an axis passing through a void and blades extending from the void. A housing: has a planar terminus defined by the housing; is rotatably mounted to the impeller such that, when the housing is positioned with the terminus horizontal and defining the housing bottom, the axis extends vertically and the impeller is above the terminus. The housing has a tubular sidewall: through which the axis extends and in which the impeller is positioned; shaped and dimensioned such that a gap is defined between the sidewall and a notional plane aligned with the terminus to direct air flow ejected from the impeller through the gap. The housing further has a screen occluding the sidewall end distal to the terminus, adapted to allow throughpassage of air and to restrict throughpassage of fingers and such that the screen has a portion that lies in the void. A motor rotates the impeller.

Abstract: Disclosed is a disposable for use with a structure having a vessel surface that defines a vessel for receiving liquid. The disposable includes a pad and a layer. The pad has a pair of surfaces spaced apart from one another by a tubular sidewall. The pad is permeable to air flow. One of the pair of surfaces is positioned, in use, against the vessel surface. The layer overlies the other of the pair of surfaces and is at least substantially impermeable to air flow. In use, gas is introduced into the pad and issues through the sidewall in the form of bubbles. The disposable is useful in association with foot spas and the like.

Abstract: A spa is provided that includes: a basin; a motor having a shaft defining a rotation axis; a hub mounted to the shaft, the hub having North and South pole domains spaced apart from each other and arranged to encircle the rotation axis in alternating relation; and an impeller which is disposed in the basin in axially spaced relation to the hub and is at least substantially constrained against movement but for rotation about the axis, the impeller including a rotor body of a non-magnetic, electrically-conductive material having relatively low magnetic permeability. The improvement in which is that there are lights and coils coupled to the impeller for rotation therewith, the lights and coils being coupled and adapted such that, in use, the rotating magnetic fields associated with the drive hub created induced currents in the coils which actuate the lights and create a net force that rotates the impeller.

Abstract: The foot spa has a rotating drive hub and a pump. The hub has North and South pole domains encircling a rotation axis in alternating relation. The pump includes a housing and an impeller, the housing having a pair of sides and defining: a cavity having a center and a periphery; an intake that communicates with the cavity center; and one or more ports communicating with the periphery. The impeller is mounted in the cavity and: defines blades which are adapted, upon rotation of the impeller in the cavity, to draw water through the intake and eject water through the one or more ports; and includes a portion that is ferromagnetic and a portion that is not ferromagnetic, the portions: being adapted such that rotation of the drive hub causes rotation of the impeller and abutting one another, one being axially displaced from the other.

Abstract: A system for use with a spa adapted for use with a pump having a drive hub. The system comprises an adapter and a disposable pump. The adapter: has a housing defining a recess, a rotor in the recess and an operative position; and is adapted, when operatively positioned: for rotation of the rotor upon rotation of the drive hub. The disposable pump has: a housing having a pair of sides and a void, one of the sides defining an intake and a port, the intake communicating with a center of the void and the port communicating with a void periphery; an impeller in the void; and an operative position adjacent the adapter. The disposable pump is adapted, when operatively positioned, for rotation upon rotation of the drive hub and consequent rotation of the rotor, to draw water through the intake and eject water through the one or more ports.

Abstract: An illuminated foot spa is provided. The foot spa has a surface which defines a basin for containing water and a pump magnetically driven by rotating magnets. A mount defines part of the surface and holds the pump against rotation. A coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of a magnetic field produced by the rotating magnets to produce a current in the coil that powers a plurality of lights operatively connected to the coil. The light conductivity associated with the mount permits the plurality of lights to be visible interiorly of the basin.
