Abstract
Abstract Disclosed is a device, intended primarily for home use, for both vacuuming and scrubbing facial skin surfaces to remove oils and debris from the skin. The device is adapted for attachment to a conventional water outlet and comprises a Venturi tube to which is attached a housing overlying the throat suction aperture of the tube. The housing accommodates a turbine rotor which is rotated by the flow of water through the Venturi throat and the rotor drives a remote facial brush. Coaxial with the rotor is a vacuum controlling rotor which may deliver continuous or pulsating vacuum. When producing pulsating vacuum, the rotor periodically interrupts or pulses the vacuum produced in the housing which, via a flexible tube, is utilized by a remote vacuum head applied by the user to his facial surfaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
A facial treatment device comprising a Venturi tube having the mouth of the converging portion adapted for attachment to a conventional bathroom water faucet, an aperture in the throat portion of said tube and a housing overlying said aperture, a turbine rotor mounted within said housing for rotation on an axis transverse to the longitudinal axis of said Venturi tube, said rotor having vanes extending through said throat aperture whereby said rotor is rotated by water moving through said Venturi tube, a remote facial brush operatively connected to said turbine rotor for rotation thereby, a vacuum controlling rotor of hollow cylindrical configuration within said housing and connected to said turbine rotor for coaxial rotation thereby, said housing having a suction aperture therein, a remote suction head connected by a flexible tube to said housing aperture, a plurality of apertures in said vacuum controlling rotor longitudinally aligned with said vacuum aperture, whereby rotation of said vacuum controlling rotor periodically opens and closes said suction aperture to pulse the vacuum appearing at the suction head caused by the static pressure reduction in said housing produced by the increase in kinetic energy of water flowing past said throat aperture.
Claim 2
Dependent Claim
196 words
A facial treatment device comprising a Venturi tube having the mouth of the converging portion adapted for attachment to a conventional bathroom water faucet, an aperture in the throat portion of said tube and a housing overlying said aperture, a turbine rotor mounted within said housing for rotation on an axis transverse to the longitudinal axis of said Venturi tube, said rotor having vanes extending through said throat aperture whereby said rotor is rotated by water moving through said Venturi tube, a remote facial brush operatively connected to said turbine rotor for rotation thereby, a vacuum controlling rotor of hollow cylindrical configuration within said housing and connected to said turbine rotor for coaxial rotation thereby, said housing having a suction aperture therein, a remote suction head connected by a flexible tube to said housing aperture, a plurality of apertures in said vacuum controlling rotor longitudinally aligned with said vacuum aperture, whereby rotation of said vacuum controlling rotor periodically opens and closes said suction aperture to pulse the vacuum appearing at the suction head caused by the static pressure reduction in said housing produced by the increase in kinetic energy of water flowing past said throat aperture.
Claim 3
Dependent Claim
71 words
A facial treatment device as claimed in claim 1 in which a rigid tubular member is interposed between said suction head and the distal end of said flexible tube, a movable tubular handle movably mounted on said tubular member, and apertures in the tubular member selectively obstructed by adjusting the position of said handle with respect to said tubular member for adjusting the degree of vaccum appearing at said suction head.
Claim 4
Dependent Claim
48 words
A facial treatment device as claimed in claim 1 in which diametric passages extend through said turbine rotor, said passages being located between the rotor blades so that the interior of said housing communicates with said throat aperture for all positions of the rotor blades with respect thereto.
Claim 5
Dependent Claim
28 words
A facial treatment device as claimed in claim 1 in which said remote facial brush has a flexible connecting means extending between the brush and said turbine rotor.
Claim 6
Dependent Claim
21 words
A facial treatment device as claimed in claim 4 in which said facial brush is detachable from said flexible connecting means.
