A pulse wall nozzle for a bathtub includes a nozzle body provided with a water inlet, a nozzle cover provided with water spray holes and a rotating roller. The nozzle body cooperates with the nozzle cover to form a cyclone cavity. The rotating roller arranged in the cyclone cavity is capable of continuously rotating to result in constant change of water outlet positions, so that the massage range is wider. The pulsed water creates a powerful and rhythmic pulsed fluid. The massage effect is not only strong and profound, but also allows users to immerse themselves in a dynamic massage movement. Venturi suction is generated at the water spray hole, so that air and water at the water spray hole are mixed to form dense bubble water, which can enhance the strength and effect of pulse massage and provide pulse massage rich in bubbles.

Disclosed is a control box. The control box is internally provided with a first chamber, and the first chamber is used for accommodating a control component. The control box is also internally provided with an air supply system for supplying air to a water pool body. 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.

Systems, apparatuses and methods for automated perineal care are provided. A system embodiment includes a user support element, a sensor configured to measure a cleanliness state of a user, a cleaning element configured to clean a user perineal area, and a controller configured to command operation of the cleaning element based on the sensor. An apparatus embodiment includes a containment structure, a sensor, a cleaning element assembly including a drive, actuator and a nozzle, and a controller configured to control the cleaning element assembly based on the sensor. A method embodiment includes positioning a user into a perineal cleaning position, scanning the user with a sensor, determining a cleanliness status, and activating a cleaning element based on the cleanliness status.

The present disclosure discloses an air passage unit for a massaging pool. The air passage unit comprises an air passing portion, a first air connecting portion, and a first fastening structure. The first air connecting portion comprises two first air connecting openings configured to be in communication with the air passing portion, the first fastening structure is configured to be detachably connected to the massaging pool, and the two first air connecting openings are disposed on the first fastening structure so as to enable the two first air connecting openings to be synchronously connected to or detached from the massaging pool through the first fastening structure being connected to or detached from the massaging pool. The present disclosure further discloses an air passage system for a massaging pool. The air passage system comprises an air pump, and an air passage unit. The air passage unit comprises an air passing portion, a first air connecting portion, and a control mechanism. The air passage unit is configured to be alternatively in an inflated state or an exhausted state. When the air passage unit is in the inflated state, a first passing passage is in communication with external air, and a second air passing passage is in communication with the first air connecting portion. When the air passage unit is in the exhausted state, the first air connecting portion is in communication with the first air passing passage through the control mechanism, and the second air passing passage is in communication with the external air through the control mechanism.
