The present disclosure provides an atomization device for a facial steamer, including a body, an atomization sheet, a heating mechanism, and an atomizing nozzle; the body is provided with a water inlet pipeline, a water outlet, and an inlet pressure balance channel; the heating mechanism is connected with the water outlet of the body; the atomization sheet is arranged between the water outlet and the heating mechanism; the atomizing nozzle is connected with a free end of the heating mechanism; the inlet pressure balance channel is communicated with the heating mechanism; a water storage cavity is formed in the body; and the water storage cavity is located on a balance path of the inlet pressure balance channel.

A control system for a swimming pool or spa may detect a water level of the swimming pool or spa. The water level may be detected based on information from an APC, information from an environmental sensor, and/or information from an optical sensor. In various embodiments, the control system may determine or estimate a cause of water displacement based on the received information from the APC, environmental sensors, and/or optical sensors.

A spa is provided including a frame, a shell mounted to the frame defining a basin for holding water, at least one sensor for monitoring a spa component or water condition, a communications interface including a cellular transceiver, and a battery for providing power to the at least one sensor and to the communications interface when the spa is not connected to a power source. The spa also includes a controller in electrical communication with the at least one sensor and the communications interface. The controller is configured to, while the spa is not connected to the power source, receive information from the at least one sensor, process the received information, and cause the communications interface to wirelessly transmit the processed information to a remote source or central server.

An induction heating system for a basin of a pedicure chair and a pedicure chair with one or more pumps and one or more heating sources are disclosed. A conducting object is located on an interior side of a first wall of the basin, with an induction heater located on the exterior side of the first wall. The conducting object is separated from the induction heater by a solid portion of the first wall. The induction heater is configured to generate a high frequency field that passes through the solid portion of the first wall and causes the conducting object to generate heat. A controller is configured to turn on/off the induction heater to maintain a desired temperature in the basin.

An air pump for dispensing air massage therapy to a basin is provided. It may be used and with a disposal liner. The air pump includes a motor, an air generator, a mounting housing member, a gasket or seal, and an air nozzle. The air pump assembly includes the air pump and the air dispenser. The air pump preferably also includes a printed circuit board (PCB), a PCB cover, an LED light, an infrared light, and a contactless fluid sensor. The present invention is also directed to a pump apparatus that includes an air pump as described, a power source, and/or a control apparatus.

A spa is provided including a frame, a shell mounted to the frame defining a basin for holding water, at least one sensor for monitoring a spa component or water condition, a communications interface including a cellular transceiver, and a battery for providing power to the at least one sensor and to the communications interface when the spa is not connected to a power source. The spa also includes a controller in electrical communication with the at least one sensor and the communications interface. The controller is configured to, while the spa is not connected to the power source, receive information from the at least one sensor, process the received information, and cause the communications interface to wirelessly transmit the processed information to a remote source or central server.

An irrigation system for use with a spa includes a water heating circuit, an automatic water fill valve connected to a water source, and an irrigation pump in fluid communication with the spa through a first irrigation line and electrically connected to a power source through a switch arrangement. The irrigation pump is adapted to pump water to at least one irrigation head. The automatic water fill valve then refills the spa from the water source. The system may include a fertilizer injector, a skin-product injector, a water softener, and various sensors running through an irrigation application on a smart phone to control the irrigation system and operation of the spa. The system may be installed

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 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.

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.
