The device includes a vessel to be filled with a mixture of water and a component producing foam, where the vessel comprises a device for blowing air into the mixture to produce foam. It is provided according to the disclosure that the device comprises at least two vessels to be filled with the mixture arranged one above the other in a vertical direction in tiers, where the vessels comprise the device for blowing air into the mixture to produce foam, where the vessels are open towards an outlet region such that the foam produced in the vessels is merged in the outlet region.

A steam physiotherapy mechanism includes a receptacle having a chamber formed in a housing, a steam pipe disposed in the housing, a steam generating device connected to the steam pipe for generating and supplying a steam into the chamber of the housing, a number of tiles disposed in the housing, and a number of retainers engaged with the tiles for anchoring the tiles in the housing, the tiles each include a number of casings each having a compartment, and one or more of the compartments of the casings are filled with an ore mud. The tiles each include a number of passages formed in the casings and communicating with the compartments of the casings.

An immersion structure (e.g., hot tub, spa, swim spa, pool, showerhead, whirlpool bathtub, and whirlpool bath) has a water treatment system that includes a nano bubble generator for purifying the water. The water treatment system can further include a gas generator that works in conjunction with the nano bubble generator to create a composition of liquid containing nano bubbles. The nano bubbles circulate in the immersion structure thereby cleaning the plumbing system and water. The water treatment system can be located within a cabinet housing the immersion structure. The system can be controlled (e.g., water treatment, operational parameters, cleaning boost, part replacement, etc.) by a user via a smart app on a client device.

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

Vertical decompression relaxation device with vertical tank, with access ladders, with handrail and stairs for internal access, and tie rods adjustable fasteners to tie rods, mainly in the treatment of muscle and fascia stiffness.

A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.

A spa has an insulated cabinet with an uninsulated shell disposed therein. A filter assembly is downstream of a water intake. A heater is downstream of the filter assembly and a pump is downstream of the heater. A diversion line is in fluid line connection with an outlet of the pump. An ozonizor is in fluid communication with the diversion line. The filter assembly is coupled to the diversion line. A data processing system is coupled to the heater, pump, a control panel and a temperature sensor, wherein the data processing system responsive to when the actual temperature of an amount of water in the shell is a magnitude in degrees below a set temperature 1) turns the heater off if it is on or does not turn the heater on if it is already off and 2) turns the pump on if it is off or if it is already running does not turn the pump off.

A pool apparatus for users to do activities in the pool apparatus. The pool apparatus includes a pool main body, one or more than one reaction deices and a control circuit. The control circuit is connected to the reaction device and controls the reaction device according to a setting to increase additional functions of the pool apparatus. When the control circuit is connected to an external device via at least one wireless network, a user may use the external device to adjust the setting. The external device does not need to be paired with the control circuit in advance. Instead, the external device interacts with the control circuit via a protocol to access and adjust the setting.

A walk-in hot tub which can enable one or more users to walk into and out of a hot tub in a dry state may include a hot tub compartment. The hot tub compartment may have a hot tub compartment interior. A tub transfer compartment may be disposed adjacent to the hot tub compartment. The tub transfer compartment may have a transfer compartment interior. An openable transfer compartment door may provide walking access to a user from outside the tub transfer compartment into the transfer compartment interior of the tub transfer compartment. An openable hot tub compartment door may provide walking access to one or more users between the hot tub compartment interior of the hot tub compartment and the transfer compartment interior of the tub transfer compartment.

A SPA pool is provided including a pool body, the pool body including a pool bottom and a pool wall together defining a water cavity. The SPA pool further includes: an inflatable seat defining therein a second air chamber and disposed in the water cavity; a first nozzle assembly, wherein at least a part of the first nozzle assembly is accommodated within the inflatable seat, and a first end of the first nozzle assembly is in fluid communication with the water cavity. The pool body further includes a fluid pipeline disposed in the first air chamber, the fluid pipeline being in fluid communication with a second end of the first nozzle assembly, so that the first nozzle assembly provides fluid communication between the water cavity and the fluid pipeline.
