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.

A manifold for an air massage system of a tub may have a housing defining an inner cavity having an air inlet configured to be pneumatically connected to a pressure source. Air outlet(s) is pneumatically connected to one or more outlets of the tub. A check valve(s) is in the inner cavity of the housing, the at least one check valve being positioned between the air inlet and the at least one air outlet relative to an air flow through the housing, the at least one check valve allowing fluid communication from the air inlet to the at least one air outlet and blocking water from flowing from the at least one air outlet to the air inlet. A width of the manifold is less than a height of the manifold.

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

A method for operating a health-care device is disclosed. The proposed method includes steps of coaxially aligning a central opening of a bottom retainer and a specific part or an acupoint of a user's body, causing a positioning device positioned on the user's body, causing a working body mounted on the bottom retainer, and operating a working piece to form a working, relation between the working end and the acupoint or the specific part, and a positional relation therebetween.

A valve assembly includes: a valve body, having an inner cavity; a first pipeline arranged on the valve body, having one end that communicates with the inner cavity and another end that is configured to be connected to an air pump; a second pipeline arranged on the valve body, having one end that communicates with the inner cavity and another end that is configured to be connected to a bubble spraying interface of a pool; and a third pipeline arranged on the valve body, having one end that communicates with the inner cavity and another end that is configured to be connected to an inflating interface of the pool. When the air pump is in an activated state, the second pipeline is in a communicating state and supplies air to the spray bubble interface, and the third pipeline is in a communicating state and supplies air to the inflating interface.

The present disclosure relates to a one-way valve (1) and an air supply system for a massage pool comprising the one-way valve (1). The one-way valve (1) includes: a valve body (10), wherein the valve body (10) has an inner cavity (11), and a first pipeline (20), a second pipeline (30) and a third pipeline 40 are arranged on the valve body. One end of the first pipeline (20) communicates with the inner cavity (11) and the other end of the first pipeline (20) is configured to be connected to an air pump; one end of the second pipeline (30) communicates with the inner cavity (11) and the other end of the second pipeline (30) is configured to be connected to a bubble spraying interface of a pool; and one end of the third pipeline (40) communicates with the inner cavity (11) and the other end of the third pipeline is configured to be connected to an inflating interface of the pool. When the air pump is in an activated state, the second pipeline (30) is able to be in a communicating state and supply air to the spray bubble interface, and the third pipeline (40) is able to be in a communicating state and supply air to the inflating interface.

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.
