A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has an opening. The heat source is coupled to an outer portion of the conduit external to the opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the opening before the combined flow enters the tub through the jet orifice.

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.

A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has a central opening. The heat source is coupled to an outer portion of the conduit external to the central opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide an atomized spray of water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the central opening before the combined flow enters the tub through the jet orifice.

An adjustable spa headrest has two side surfaces laterally disposed between front and back surfaces. A first projection extends outwardly from one of the side surfaces. A guide rail, positioned for receiving the projection, allows the spa headrest to be positioned in a number of positions. The guide rail includes a horizontal slot, a vertical slot including a number of spaced notches, each notch defined by a pair of second projections, and a spring arm depending in the vertical slot. When the first projection moves to a position between one of the second projections and the spring arm, the spring arm moves away from the second projection whereupon the spring arm applies a spring force to the first projection in a direction of second projection. In response to positioning the first projection in one of the notches, the spring arm secures the first projection in the one of the notches.

A magnetic couple jet for hydrotherapy spa equipment contains: a motor, a fixer, and a water jet assembly. The motor includes a rotary shaft and a magnet disc set. The fixer includes a first positioning holder and a second positioning holder, wherein the second positioning holder includes a coupling face and at least one first affix portion. An accommodation chamber is defined between the second positioning holder and the first positioning holder so as to accommodate the rotary shaft and the magnet disc set of the motor. The water jet assembly includes a covering member, an impeller, and a magnet, wherein the covering member has a holding seat, a cap, and a receiving room. The holding seat has an orifice, at least one second affix portion, at least one inlet, and at least one outlet. The impeller has multiple fans, a column, and a housing groove formed.

A bathtub assembly includes a bathtub shell containing a volume of liquid, a circulation system in communication with the shell for creating a flow of liquid to and from the shell, and a dispenser assembly for introducing a substance into a portion of the flow of liquid into the bathtub shell. A control panel is rotatably mounted on an upper rim of the bathtub shell proximate to an inlet to the dispenser assembly and rotates to alternately cover or expose the inlet. A plurality of directed flow jets are connected to the bathtub shell for conveying the flow of liquid into the shell to create a directed flow of liquid within the bathtub shell.

A water jet assembly includes a faceplate with at least one opening, a housing constructed to cooperate with the faceplate, and a mover disposed within a chamber of the housing. The mover is configured to move between a first position adjacent the at least one opening of the face plate and a second position offset from the faceplate to provide a variable volume within the chamber. The water jet assembly also includes an exciter connected to the housing and configured to transition the mover between the first position and the second position to increase and decrease the volume to move fluid into and out of the chamber via the at least one opening.

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.
