A method of purging a whirlpool bathtub includes providing a pump having an off condition and an on condition, the pump configured to circulate water to a basin through a water feed line. The method further includes providing a blower having an off condition and an on condition, the blower configured to provide air to the basin through an air feed line. The method further includes turning the blower to the on condition and the pump to the off condition, and introducing at least a portion of the air from the blower into the water feed line.

A bathtub device for bubble bath physiotherapy, wherein the bathtub body is mounted on the bathtub body support. The exhaust system of the bathtub device is mounted in a space between the bathtub body and the bathtub body support. A fan is configured for delivering gas. The air suction inlet ends of the air suction pipe are configured to be in communication with the upper open side of the bathtub body, and the air suction outlet end is connected to the air inlet side interface device of the fan. The exhaust inlet end of the exhaust pipe is connected to the air outlet side interface device of the fan. The present invention further provides a bubble bath physiotherapy system comprising the bathtub device. By using the bathtub device, a safer bubble bath can be achieved.

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.

A footbath has a base member defining a platform. A flexible continuous side wall extends from a proximal end region connected about a periphery of the base member to a distal end region. The side wall has a collapsed position and an extended position. The platform of the base member and the side wall cooperate to define a bath chamber for retaining water with the bath chamber sized to receive a body part. A retention member is supported by the base member to extend from the base member to the distal end region of the side wall to retain the side wall in the extended position.
