A jet pump associated with a heat source, such as a heating element or heating coils, is disclosed. The heating element is located in a housing chamber and coaxially with an impeller. An electrical motor rotates the impeller and circulates water within the chamber and between coils of the heating element. The heated water is then discharged into a basin found in a pedicure chair or other devices requiring agitated, heated water.

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 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 whirlpool bath with descaling function is provided. The whirlpool bath 1 comprises a bathtub body 10 including a bathtub 11, suction port 20 sucking the water contained in the bathtub 11, first jet nozzles 30 jetting bubble water into the bathtub 11, a circulation pipe 40 including a water supply pipe 41 and a return pipe 42, a pump 50 installed in the circulation pipe 40, a bypass pipe 60 branched from the water supply pipe 41 and connected to the return pipe 42 to directly return the water in the water supply pipe 41 to the pump, and a second jet nozzle 70 mixing air with water passing through the bypass pipe 60 to generate and jet bubble water. The scale of the circulation pipe 40, the pump 50 and the bypass pipe 60 is removed by bubble water generated by the second jet nozzle 70.

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 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 bathtub (1) which comprises: a main body (2) having side walls (22, 22a, 22b), at least one of which presents an inner surface provided with guide means (3); supporting means (4) engaged with guide means (3) and configured for supporting at least a portion of user's body in order to allow, in use, simulating user flotation.

A massage bathing maintenance system suitable for a massage bathing equipment is provided. The system comprises at least one attached device, at least one slave control device, a master control device, and an analyzing unit. The at least one attached device is configured to actuate with regard to the massage bathing equipment. The at least one slave control device comprises a control unit configured to generate and transmit at least one actuating message according to at least one actuating-status of the at least one attached device. The master control device comprise a log-collecting unit configured to record the at least one actuating message of the at least one slave control device into a logs table. The analyzing unit is configured to analyze the at least one actuating message of the logs table so as to determine whether the actuation of at least one attached device is abnormal.

A spray rod and an intelligent toilet are provided. The spray rod comprises: a body, a body water passage being formed in the body; a nozzle assembly, arranged separately from the body, the nozzle assembly having a nozzle communicated with the body water passage; a vibration motor, provided in the nozzle assembly, so that the vibration motor drives the nozzle assembly to vibrate when the vibration motor operates, and washing water sprayed from the nozzle at least swings in the transverse direction. The spray rod generates pulsating water in the transverse direction by using vibration, provides a novel flushing water splash, and improves the flushing effect.
