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.

Disclosed is a disposable for use with a surface that defines a basin for receiving liquid. The disposable has a pair of surfaces spaced apart from one another by a tubular sidewall. One of the pair of surfaces is positioned, in use, against the basin-defining surface. In use, gas issues through the sidewall in the form of bubbles. The disposable is useful in association with foot spas and the like. A mechanism for puncturing a liner is also disclosed.

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

The present invention relates to the technical field of massagers, and discloses a multipurpose thermostatic underwater massager, which includes a thermostatic principal machine, a duct switch for controlling output of gas flow, a cushion, an air outlet duct, an air outlet handle, and a first soft duct and a second soft duct for conveying gas flow. The duct switch is installed at the air outlet of the thermostatic principal machine, and the first soft duct and the second soft duct are respectively connected with the two outlets of the duct switch. The outlet of the second soft duct is communicated with the cushion, and the two ends of the air outlet duct are respectively communicated with the front and back of the cushion.

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.

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

An air connection pipeline device of a massage pool may comprise a pipeline. The pipeline may be formed with a first air connection passage and a second air connection passage. The first air connection passage may have a first air inlet and a first air outlet. The first air connection passage may include a check valve located between the first air inlet and the first air outlet. The check valve may be driven to open when the air flow moves from the first air inlet to the first air outlet and close when reversely. The second air connection passage may be provided with a switch valve. The switch valve may comprise a second valve core and a second elastic body. The second valve core may slide between a closed position to close the second air connection passage and an open position to open the second air connection passage. The second elastic body may press against the second valve core. An initial state of the second valve core may be the closed position.

An airway structure of a massage pool may include a control valve. The airway structure may comprise an air connection passage with an air connection port and a control plate rotatable relative to the air connection port. A control valve may be installed at the air connection port. The control valve may have a valve core portion that can slide between an open position and a closed position relative to the air connection port. The control plate may be provided with a ventilation port, an open area and a closed area. A position of the open area and the closed area may be controlled by the rotation of the control plate to match the valve core portion. The control plate and the valve core portion may be in a transmission connection and the rotation of the control plate may drive the valve core to slide, and the valve core portion is in the open position through the cooperation of the open area and the valve core portion to open the air connection port and the ventilation port and the air connection port are connected, and the valve core portion is in the closed position through the cooperation of the closed area and the valve core portion to close the air connection port.
