Abstract
A swim mask apparatus having a mask equipped with a floating air-suction device is provided. The mask includes a plurality of straps extending from two lateral sides thereof to firmly attach the mask to a wearer's head and thereby provide watertight protection for the wearer's eyes and nose. The mask is provided with a one-way exhaust valve and a one-way sniffing valve. The floating air-suction device includes a float and an air hose extending therefrom. A terminal end of the air hose is connected to the one-way sniffing valve to form an inhalation airway between the float and the mask. The buoyancy of the float normally maintains the open end of the air hose coupled thereto above the water surface. When it is pulled sufficiently below the water surface by the air hose, the buoyant float is resistive to the displacement to the extent that compressing members formed therein constrictively engage the end of the air hose to prevent water from entering therethrough.
