ABSTRACT:
This invention relates to a control device for an air turbulence massage device having a housing. The housing accommodates a blower unit which can be driven by an electrical motor. The housing has a connecting piece for an air tube that is in communication with a turbulence matting. The housing accommodates a check valve device which, when the control device is shut off, prevents water from flowing back from the turbulence matting to the electrical motor and the blower unit. The housing comprises an external housing and a separate internal housing. Air flow is separated from a water discharge path leading from the internal housing such that the blower unit and the electrical motor never contact the water flowing into the housing and the water can flow out of the control device.
