An aeration nozzle for spraying water infused with air into an above-ground water cavity defined by a wall, comprising a nozzle body having at least a first internal conical portion including an upstream end and a downstream end, the downstream end being smaller than the upstream end, a water way extending through the nozzle body and the first internal conical portion, an air way extending through the nozzle body, the air way intercepting the water way within the nozzle body downstream of the first internal conical portion, and a check valve disposed along the air way that permits air to be pulled through the air way and into the water way by way of a vacuum force caused by water flowing within the water way through the first internal conical portion and prevents water from entering the air way.

A device and method for producing pulsating waves of energy for the massaging effect normally associated with high pressure jet systems in whirlpools, pedicure spas, bathtubs and other medical and non-medical devices. The jet assembly includes no external pipes and unlike pipeless jet assembly systems in use today, does not require disassembly or circulation of chemical cleaning agents to maintain a sanitary condition of the jet assembly.

A massage pillow configured to be positioned over a fluid jet includes a cushion and a retaining assembly. The cushion includes a front surface, a rear surface, and side surfaces extending there between. The rear surface includes an annular edge defining an opening providing access to an interior of the cushion sized to at least partially cover the jet. The retainer assembly includes an opening configured to align with the jet and a peripheral edge configured to retain the annular edge of the cushion. The retainer assembly is configured to be removably fixed to a wall surrounding the jet with the jet aligned with the opening of the retainer assembly and the opening of the cushion, such that fluid expelled from the jet passes into the interior of the cushion, so that the pillow provides massage and/or warmth due to the expelled fluid.

A bathtub includes a bathing well having a rim and an inner well defined in the rim. The bathtub further includes a rim cap disposed over the rim and an electronic component disposed in at least one of the inner well or the rim cap.

Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

A foot spa tub includes a tub basin, a first magnetic drive member rotatably coupled to a drive motor, and a first casing supporting the magnetic drive member. The first casing is disposed against an exterior surface of a sidewall of the basin. A second magnetic drive member is rotatably coupled to a blade. The first and second magnetic drive members are magnetically coupled to each other so that the blade is drivingly coupled to the drive motor. A nozzle houses the second magnetic drive member and the blade. The nozzle is detachably securable to an interior surface of the sidewall by a magnetic attraction force between the first and second magnetic drive members. A method of circulating liquid in a foot tub spa is also provided.

This disclosure relates generally to jets for spas and, more specifically, to jets that can be adjusted laterally along a width of the proximal end of the jet housing. The angular adjustment of the proximal outlet of the jet may be at least 30?. In some embodiments, the jet assembly includes a housing with a distal inlet at a distal end of the housing and a proximal outlet at a proximal end of the housing, the proximal outlet laterally adjustable along a width of the proximal end of the housing, with the proximal outlet maintaining a constant depth with respect to the proximal end of the housing as the proximal outlet is laterally adjusted along the width of the proximal end of the housing.

An air pump for dispensing air massage therapy to a basin is provided. It may be used and with a disposal liner. The air pump includes a motor, an air generator, a mounting housing member, a gasket or seal, and an air nozzle. The air pump assembly includes the air pump and the air dispenser. The air pump preferably also includes a printed circuit board (PCB), a PCB cover, an LED light, an infrared light, and a contactless fluid sensor. The present invention is also directed to a pump apparatus that includes an air pump as described, a power source, and/or a control apparatus.

A water valve and a pool are provided. The water valve includes a valve body having a first channel; and a valve plate having a valve plate opening and configured to control opening or closing of the first channel by sliding; when the valve plate is in a first position, the valve plate opening is aligned with the first channel and water can flow through the first channel, the water valve is opened; when the valve plate is in a second position, the first channel is blocked by the valve plate, the water valve is closed. The pool includes a water inlet part connected with a pool wall and the water valve detachably connected with the water inlet part. The water valve is simple in operation, has good sealing performance and switch function of the water valve and disinfection function of the chemical dispenser, thereby improving the water valve's performance.
