Air-foam generating apparatus for bath

Claim 2

In a foam-bathing apparatus, an air-foam generating apparatus for use beneath a body of bathing water comprising a hollow case including a porous foam-generating plate overlying the hollow case, said porous plate including a plurality of meandering passages communicating outer and interior surface of said porous plate with the interior of said case; means for directing pressurized air into said hollow case and out through said porous plate passages for passing through the body of bathing water, said passages having diameters ranging from 0.013 mm to 0.48 mm and producing sonic waves when pressurized air is forced through said passages so that a user's skin is subjected to both frictional and vibrational stimuli by air-foams generated beneath the surface of the body of bathing water and engaging a user's skin, said generating plate consisting of a porous porcelain material comprising sintered aluminum oxide grain vitrified (Al 2 O 2 ) produced at a high temperature with the use of an inorganic bonding agents.
