The invention provides a multifunctional vibrator for hydrotherapy and air therapy. The multifunctional includes a casing and a rotation disc. The casing includes a housing and an end cap. The rotation disc is rotationally disposed in the casing. An inner hole of the rotation disc and a water inlet of an outer hole unit of the housing are both axially arranged, and thus the inner hole and the water inlet are axially communicated and press each other. Furthermore, the interface of the inner hole and the water inlet is a plane, by means of which a gap between the water inlet and the inner hole can be easily reduced. In addition, when a water flow and an air flow go through the inner hole and the water inlet, the water flow and the air flow can drive the rotation disc onto the housing and thus also reduce the gap. Therefore, the multifunctional vibrator for hydrotherapy and air therapy can prevent the water flow or air flow from overflowing from the gap, thereby ensuring therapeutic effects of hydrotherapy and air therapy by maintaining certain pressure.本創作係用於水療或氣療用的多功能振波器,其包含有一殼體及一轉動盤,殼體包含有一外殼及一端蓋,轉動盤可相對轉動地設於殼體內;藉由使轉動盤的內孔軸向設置,並且外殼的外孔單元的進水口亦軸向設置,因此內孔與進水口為軸向地相通及相貼靠,並且內孔與進水口的交界面為一平面,藉此可輕易地降低進水口與內孔的間隙;此外,當水流及氣流通過內孔與進水口時,水流及氣流亦會連帶將轉動盤推抵於外殼上而同樣可降低該間隙;本創作藉此可有效避免水流或氣流通過時從該間隙溢散而出,並因此得以維持一定之壓力以確保水療及氣療的療效。10‧‧‧殼體20‧‧‧外殼21‧‧‧裝設孔22‧‧‧限位部23‧‧‧外孔組24‧‧‧外孔單元241‧‧‧進水口242‧‧‧出水口2422‧‧‧出水口244‧‧‧套筒槽245‧‧‧螺孔246‧‧‧防漏墊圈30‧‧‧端蓋31‧‧‧裝設孔32‧‧‧入水孔33‧‧‧接管34‧‧‧移動部35‧‧‧移動孔40‧‧‧防撞套筒組41‧‧‧防撞套筒50‧‧‧轉動盤51‧‧‧裝設孔52‧‧‧內孔組521‧‧‧內孔60‧‧‧裝設件61‧‧‧軸孔63‧‧‧墊片
