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.
