An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

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.

Air injectors are provided for conveying fluid and/or gas (e.g., air) into the fluid of a bathing apparatus. The air injectors can include a component for attachment to an outside surface of the bathing apparatus that can be hidden from the view of a user and another component for attachment to a source of the fluid and/or gas (e.g., air). The two components can be connected together for use or disconnected for servicing and cleaning the injectors, as well as servicing a check valve or the injectors.

In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

An inflation system, a massage pool air supply system, and an inflation method. The inflation system includes: a first gas channel (20) and a second gas channel (30); the first gas channel (20) has a gas inlet port and a gas outlet port; the gas inlet port is used for being connected to a gas supply apparatus (10), and the gas outlet port is used for communicating with a gas chamber (51) of the inflated object (50); the first gas channel (20) can be switched between a first state and a second state; the second gas channel (30) is arranged in parallel to the first gas channel (20); the second gas channel (30) is used for communicating with the gas chamber (51); a gas pressure sensor (40) is provided on the second gas channel (30); in the first state, a gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) does not reach a set value, and the first gas channel (20) can inflate the gas chamber (51); in the second state, the gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) reaches the set value, and the first gas channel (20) can stop inflating the gas chamber (51). The inflation system can prevent over inflation and can effectively protect the inflated object.

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.
