The air supply system comprises an air suction part having a housing, the housing is provided with an air inlet and an air outlet, and the air inlet is communicated with the first chamber; the air suction part further comprises an air pump provided in the housing, and when the air pump is started, air in the first chamber can be suctioned into the housing by means of the air inlet. The air supply system further comprises a valve part provided with a pipeline, the pipeline is provided with an air intake port and an air supply port, the air intake port is communicated with the air outlet of the housing, and the air supply port is used for being communicated with the water pool body; when the valve part is opened, the air suctioned into the housing can flow into the water pool body along the pipeline. According to the present invention, the working environment in the first chamber can be kept dry, so that the service life of the control component is prolonged. The present invention further provides a massage water pool.

A water distribution system for providing multiple bathing functions independently for a walk-in bath tub using one pump that delivers pressurized water to a first valve having a first outlet for communicating pressurized water to a second valve and a second outlet for communicating pressurized water to a drain, the second valve selectively positioned for communicating pressurized water selectively to a respective piping system for a micro bubbles bathing function and for a pressurized jet bathing function, and a controller for moving the valves selectively to provide three operational bathing functions independently with the one pump. A method for providing multiple bathing functions independently with one pump is disclosed.

The present disclosure provides a hydrogen generation and dispersion device and methods of making and using the same.

A terminal product usable time management system includes a remote server and a local apparatus. The local apparatus includes a data memory storing an identifier and an encrypted usable time of the terminal product, a microprocessor used to send a start notification of a usable time management process, a product controller used to control a product load, and a wireless networking device used to communicate with the remote server to receive a new expiry date to update the usable time. The usable time management process includes: reading the encrypted usable time stored in the data memory, decrypting the encrypted usable time, decreasing the usable time per time unit, encrypting the decreased usable time, storing the encrypted and decreased usable time into the data memory, and instructing the product controller to disable some or all functions of the terminal product, if the usable time is inaccessible or decreased to zero.

A steam generator for a shower steam system includes a first chamber, a second chamber, and an intermediate heat transfer member. The first chamber is configured to receive water. The second chamber is configured to receive a flow of air. The intermediate heat transfer member fluidly separates the first chamber from the second chamber. The intermediate heat transfer member includes a heating element configured to generate heat energy. The intermediate heat transfer member is configured to transfer heat energy generated by the heating element to the first chamber to generate steam in the first chamber, and transfer heat energy generated by the heating element to the flow of air in the second chamber.

A passive cooling system for an electric motor drive circuit in a bathing installation, including a section of hollow pipe made of a thermally conductive tubing material, the pipe configured to form part of a water recirculation path of the bathing installation. An adapter structure has a conformal surface configured for attachment to an outer surface of the pipe and a circuit contacting surface for attachment to the motor drive circuit, the adapter structure fabricated of a thermally conductive adapter material. The adapter structure provides a thermal conductive path between the motor drive circuit and the pipe section, configured to pass heat generated by the circuitry to the pipe section and into spa water flowing through the water recirculation path, to cool the circuitry and warm the spa water.

The present invention discloses a therapeutic device includes a bubble generator configured to generate bubbles. The systems consists of a water pump, a diffuser to diffuse CO2 into the water, a sensor for temperature, a tank for CO2, a pressure regulator to lower the CO2 pressure from the tank, a solenoid valve to turn off and on the flow of CO2, a controller to control the system and a display to show the conditions of the system's operation.

An agent analysis system includes a terminal product system, a remote diagnosis system (RDS), and an agent analyzer. The terminal product system is supplied with a power source and provided with a current sensor to sense the power source. The RDS is used to transmit at least one control instruction via internet for the terminal product system. They agent analyzer is used to communicate with the terminal product system and the RDS, and configured to measure and analyze the electricity use characteristics of the terminal product system to be transmitted to the RDS; and receive and convert the control instruction from the RDS via internet for the terminal product system.
