Pneumatic massage machine

Claim 2

A pneumatic massage machine comprising a semi-spherical vibratory massage head having a construction allowable of dispersion of liquid therethrough, means for pneumatically driving said massage head for vibration and connected to a given supply source of compressed air, a main cylindrical body carrying said massage head via said pneumatic driving means, a liquid reservoir disposed to said main cylindrical body and connected to said massage head for supply of said liquid, means for forcibly discharging said liquid out of said liquid reservoir upon application of user's finger action thereto and operationally coupled to said liquid reservoir.

Claim 3

A pneumatic massage head as claimed in claim 1 in which said massage head is made of an elastic material.

Claim 4

A pneumatic massage head as claimed in claim 1 in which said massage head is provided with an axial nose hole for dispersion of said liquid.

Claim 5

A pneumatic massage machine as claimed in claim 1 in which said massage head is provided with a finely porous construction allowable of passage of said liquid therethrough.

Claim 6

A pneumatic massage machine as claimed in claim 1 in which said liquid reservoir and said discharging means are mounted outside said main cylindrical body.

Claim 7

A pneumatic massage machine as claimed in claim 5 in which said pneumatic driving means includes a main body coupled to the front end of said main cylindrical body, internally defining an operation chamber and having an air conduit opening at one end in said operation chamber and an air vent opening at one end in said operation chamber and at the other end in the interior of said main cylindrical body, a rotor accommodated within said operation chamber in a freely rotatable and revolvable disposition, a front cover coupled to the front side of said main body, carrying said massage head, and having a liquid conduit opening in the front face thereof in order to allow introduction of said liquid into said massage head for dispersion, and a hose pipe connected at one end to the other end of said air conduit formed in said main body and at the other end to said given supply source of compressed air.

Claim 8

A pneumatic massage machine as claimed in claim 6 further comprising means for damping noises to be generated by the air discharged from said operation chamber.

Claim 9

A pneumatic massage machine as claimed in claim 7 in which said damping means includes at least one bulkhead formed within said main cylindrical body while leaving an annular gap around said hose pipe, the outer diameter of said annular gap being smaller than the inner diameter of said main cylindrical body.

Claim 10

A pneumatic massage machine as claimed in claim 8 in which a pair of bulkheads are arranged being spaced from each other in the axial direction of said main cylindrical body.

Claim 11

A pneumatic massage machine as claimed in claim 6 in which the interior of said liquid reservoir is connected to said liquid conduit of said front cover via a liquid pipe.

Claim 12

A pneumatic massage machine as claimed in claim 5 in which said discharging means includes an elastically deformable cylindrical body mounted outside said main cylindrical body in an arrangement suited for finger pressing, a first check valve disposed to the front end of said deformable cylindrical body and adapted for introduction of atmospheric air into a first air reservoir formed in said deformable cylindrical body, a second check valve disposed to a rear closure of said deformable cylindrical body and adapted for introduction of air in said first air reservoir into a second air reservoir formed in said rear closure, and an air pipe connecting said second air reservoir to the interior of said liquid reservoir.

Claim 13

A pneumatic massage machine as claimed in claim 1 in which said liquid reservoir and said discharging means are accommodated within said main cylindrical body.

Claim 14

A pneumatic massage machine as claimed in claim 12 in which said pneumatic driving means includes a main body suspensorily encased within said main cylindrical body, internally defining an operation chamber, and having an air conduit opening at one end in said operation chamber and an air vent opening at one end in said operation chamber and at the other end in the interior of said main cylindrical body, a rotor accommodated within said operation chamber in a freely rotatable and revolvable disposition, a front cover coupled to the front side of said main body, carrying said massage head outside said main cylindrical body, and having a liquid conduit opening in the front face thereof in order to allow introduction of said liquid into said massage head for dispersion, means for placing said front cover in resilient pressure contact with the front wall of said main cylindrical body, and a hose pipe connected at one end to the other end of said air conduit formed in said main body and at the other end to said given supply source of compressed air.

Claim 15

A pneumatic massage machine as claimed in claim 13 in which said placing means includes a compression spring interposed between said main body and said discharging means.

Claim 16

A pneumatic pressure machine as claimed in claim 13 in which a slide disc is inserted between said front cover and said front wall of said main cylindrical body.

Claim 17

A pneumatic massage machine as claimed in claim 12 in which said discharging means includes a flange intervening between front and rear halves of said main cylindrical body, and having a liquid conduit and an air conduit both opening in the front face thereof and a check valve disposed to the front end of said air conduit, said front half of said main cylinder defining a cylindrical chamber for accommodating said pneumatic driving means, said rear half of said main cylindrical body accommodating said liquid reservoir, and said check valve allowing introduction of air from said cylindrical chamber into said air conduit, and an annular piece disposed to the periphery of said front half of said main cylindrical body for communication of said cylindrical chamber to the atmosphere.

Claim 18

A pneumatic massage machine as claimed in claim 16 in which said liquid conduit formed in said flange is connected at one end to said massage head and at the other end to the interior of said liquid reservoir, and said air conduit formed in said flange is connected to the interior of said liquid reservoir.
