摘要: A toy bathtub device for simulation of giving a doll shower or bubble bath, the like. The includes base tub portion having an upstanding post supporting showerhead which spray nozzle. curtain is mounted on preventing undue splashing water from nozzle and tub. supplied with through conduit by bellows-like pump operates in combination check valve to recycling fashion reservoir thence provided drain plug draining into reuse. floor also aeration system form peripheral series perforations ports bottom wall are interconnected manifold. manifold air under pressure another bellows acting against valve. Each pumps individually controllable separate manually operable pumping handle accessible exterior so that child, play, can select activation and/or bubbling both simultaneously.
