A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

An automatic pipe clean system for massage bath equipment includes a bathtub, a water-filling pipe, a water-draining pipe, a suction pipe, a pump pipe, a pump connected between the suction pipe and the pump pipe, an automatic water-filling pipe, a water-filling valve and a controller. The controller is configured to: in a cleaning stage: turn on the pump to allow the water to pass and clean the suction pipe and the pump pipe; and in a drying stage: turn on the pump to allow the water to drain out from the suction pipe and the pump pipe; and turn off the pump.

There is disclosed a spa. The spa generally having a unibody shell having a base, a peripheral wall extending from the base up to a rim portion, a basin suspended from the rim portion, and at least one opening in the peripheral wall, the basin, the rim portion, the peripheral wall and the base defining a cavity therebetween, the at least one opening exposing the cavity, the base having a pair of channels recessed from the base towards the cavity; and a modular panel having a main panel covering the opening while exposing the pair of channels, and a subpanel engageable to the main panel and covering at least partially the pair of channels.

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 manifold to be used in a hot tub plumbing system is provided, the manifold including an intake port configured to be coupled to a water pump in the hot tub plumbing system, and a plurality of output ports configured with connecting portions to connect with tubing to supply water from the water pump to a corresponding plurality of jets in the hot tub plumbing system.

A hydrotherapy apparatus, which utilizes the configuration between a sprinkler piping, a reflow piping, a sterilizing piping and a drainage pipe and the operation of a medical motor to control the concentration of a fluid mixture of a medicament and cold water such that each cleaning and sterilizing process does not need to replenish water, saving much time and avoiding waste of water resources. Further, the hydrotherapy apparatus enables the medicament fluid to be maintained at a predetermined concentration to provide a sufficient sterilization effect, and can effectively and completely drain off waste water after the cleaning process, preventing cross-infection between different users.

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 walk in bath includes a shell, a door, and a seal member. The shell defines a bathing area and includes a wall with an opening therein. The door is moveable relative to the wall between a closed position, in which the door engages the opening, and an open position allowing ingress into and egress from the bathing area through the opening. The seal member is located between the wall and the door in the closed position to seal a gap therebetween to prohibit water from leaking from the bathing area through the gap. The seal member includes a first end, a second end, and an intermediate hollow section extending between the first and second ends. Each of the first and second ends is closed to prevent water from entering into the seal member.

A method and a control panel are described for facilitating the control of a bathing unit system so that the bathing unit system is caused to transition between operating in accordance with a first operational mode to operating in accordance with a second operational mode. A control signal is generated in response to a unitary user input event performed by a user at a control panel of the bathing unit system, the control signal conveying an ambiance activation command associated with a specific ambience setting, the generation of the control signal comprising selecting the specific ambience setting from a set of ambience settings stored in a memory device. The control signal is then transmitted from the control panel to the controller over a communication link where it is processed to cause the bathing unit system to transition from being in the rest mode to operating in accordance with the specific ambience setting. The method and a control panel may allow simplifying the control of the bathing unit system in order to achieve a desired total effect by allowing a user to cause the bathing unit to operate in accordance with an ambience setting by way of a unitary user input event performed at the control panel.
