Abstract
Abstract A cleaning device for the removal of excrement and extraneous matter from a surface such as human skin and the like, which device includes a trough-like intake channel having a suction passage connectible to a vacuum source for effecting the passage of material from the surface being cleaned to the vacuum source. A filter element is supported in line with the suction passage to retain solid particles removed from the skin while allowing passage of fluids therethrough, and a fluid discharge passage is connectible to a source of liquid washing medium for selectively discharging the liquid onto the skin surface to loosen matter to be removed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
276 words
A cleaning device for cleaning a surface such as human skin and the like through the removal of excrement and semi-liquid matter from the surface by suction, said device comprising: body means including an inner core portion and an outer skirt portion; said inner core portion having side wall surfaces, front and rear ends, and a substantially flat lower surface; said inner core portion having a suction passage therein communicating with said front and rear ends thereof; said outer skirt portion being defined by a skirt wall which is connected at its upper edge to said inner core portion and which includes a portion spaced outwardly from said front end and side wall surfaces of said inner core portion to define an air channel between said inner core portion and said skirt wall; said skirt wall having edge surface portions adapted for engagement with the surface to be cleaned in a manner to maintain said flat surface of said inner core in spaced relation from the surface being cleaned; said skirt wall and said flat surface of said inner core portion defining an intake opening generally adjacent said rear end of said core portion for the entry of matter removed from the surface being cleaned when said device is disposed in an operating position; said skirt wall having at least one opening therein for the entry of breather air into said air channel; and means at said rear end of said inner core portion for connecting said suction passage to a source of vacuum such that material removed from the surface being cleaned is caused to pass through said suction passage toward the source of vacuum.
Claim 2
Dependent Claim
276 words
A cleaning device for cleaning a surface such as human skin and the like through the removal of excrement and semi-liquid matter from the surface by suction, said device comprising: body means including an inner core portion and an outer skirt portion; said inner core portion having side wall surfaces, front and rear ends, and a substantially flat lower surface; said inner core portion having a suction passage therein communicating with said front and rear ends thereof; said outer skirt portion being defined by a skirt wall which is connected at its upper edge to said inner core portion and which includes a portion spaced outwardly from said front end and side wall surfaces of said inner core portion to define an air channel between said inner core portion and said skirt wall; said skirt wall having edge surface portions adapted for engagement with the surface to be cleaned in a manner to maintain said flat surface of said inner core in spaced relation from the surface being cleaned; said skirt wall and said flat surface of said inner core portion defining an intake opening generally adjacent said rear end of said core portion for the entry of matter removed from the surface being cleaned when said device is disposed in an operating position; said skirt wall having at least one opening therein for the entry of breather air into said air channel; and means at said rear end of said inner core portion for connecting said suction passage to a source of vacuum such that material removed from the surface being cleaned is caused to pass through said suction passage toward the source of vacuum.
Claim 3
Dependent Claim
29 words
A cleaning device as defined in claim 1, and further including leak air openings adjacent said rear end of said inner core portion and communicating with said air channel.
Claim 4
Dependent Claim
79 words
A cleaning device as defined in claim 1 wherein said air channel extends from said rear end of said inner core portion along one of said side wall surfaces of said core, along said front end of said inner core portion and along the other of said side wall surfaces of said core to the rear end of said inner core portion, said skirt wall having a lower edge sUrface adapted for contact with the surface to be cleaned.
Claim 5
Dependent Claim
38 words
A cleaning device as defined in claim 1 wherein said skirt wall has a pair of laterally spaced elongated openings adjacent the upper edge of said skirt wall for the entry of breather air into said air channel.
Claim 6
Dependent Claim
235 words
A cleaning device for cleaning a surface such as human skin and the like through the removal of excrement and semi-liquid matter from the surface by suction, said device comprising: body means including an inner core portion and an outer skirt portion; said inner core portion having side wall surfaces, a front end surface, and a substantially flat lower surface; said inner core portion having a suction passage therein communicating with said front end surface, said outer skirt portion being defined by a skirt wall connected at its upper edge to said side wall and front end surfaces of said inner core portion and having a lower edge surface disposed below the plane of said flat lower surface and adapted for engagement with the surface to be cleaned in a manner to maintain said flat lower surface of said inner core in spaced relation from the surface being cleaned so as to define an air channel which underlies said flat surface and has an intake opening generally adjacent said rear end of said core portion such that air entering said intake opening flows through said air channel substantially tangential to the surface being cleaned, said skirt wall having at least one opening therein to permit the entry of breather air into said air intake channel in a manner to cause increased cleaning action by air turbulence and prevent suction adherence to the surface being cleaned.
Claim 7
Dependent Claim
235 words
A cleaning device for cleaning a surface such as human skin and the like through the removal of excrement and semi-liquid matter from the surface by suction, said device comprising: body means including an inner core portion and an outer skirt portion; said inner core portion having side wall surfaces, a front end surface, and a substantially flat lower surface; said inner core portion having a suction passage therein communicating with said front end surface, said outer skirt portion being defined by a skirt wall connected at its upper edge to said side wall and front end surfaces of said inner core portion and having a lower edge surface disposed below the plane of said flat lower surface and adapted for engagement with the surface to be cleaned in a manner to maintain said flat lower surface of said inner core in spaced relation from the surface being cleaned so as to define an air channel which underlies said flat surface and has an intake opening generally adjacent said rear end of said core portion such that air entering said intake opening flows through said air channel substantially tangential to the surface being cleaned, said skirt wall having at least one opening therein to permit the entry of breather air into said air intake channel in a manner to cause increased cleaning action by air turbulence and prevent suction adherence to the surface being cleaned.
Claim 8
Dependent Claim
48 words
A cleaning device as defined in claim 5 wherein said body means includes a nozzle portion and a handle portion, said handle portion comprising a tubular member releasably connected to said nozzle portion and having means thereon for releasably connecting said handle portion to a source of vacuum.
Claim 9
Dependent Claim
48 words
A cleaning device as defined in claim 5 including a filter element supported by said means in said suction passage means, said filter element being adapted to retain solid particles received therein from said suction passage means while allowing liquid to pass therethrough toward said source of vacuum.
Claim 10
Dependent Claim
37 words
A cleaning device as defined in claim 5 wherein said body means includes air leak openings allowing the entry of air into said air intake channel when said device is disposed against a surface during cleaning thereof.
Claim 11
Dependent Claim
30 words
A cleaning device as defined in claim 6 wherein said handle portion is released from said nozzle portion by effecting relative rotation between said handle portion and said nozzle portion.
