The brush head has a locking cavity formed therein and the handle has a locking rib formed thereon. The locking rib is removably received within the locking cavity by which the brush head and the handle are retained one above the other when the handle is rotated to its folded position below the brush head. The handle includes a hollow fluid chamber running therethrough. A spray pump is detachably connected to the handle so that a spray tube communicates with the hollow fluid chamber to enable a fluid to be sprayed therefrom. ## Claims ### Claim 1 A rotatable brush, comprising: a brush head having a set of bristles projecting therefrom to brush a contact surface; a handle pivotally connected to said brush head to be held in the hand of a user to manipulate said brush head over the contact surface; and a hinge by which said handle is pivotally connected to said brush head so that said handle is rotatable relative to said brush head between an unfolded position lying end-to-end and axially aligned with said brush head and a folded position lying below said brush head. ### Claim 2 (depends on 1) The rotatable brush recited in claim 1, wherein opposing ends of said brush head and said handle have respective locking lips, said locking lips being detachably mated together to retain said handle in said unfolded position lying end-to-end and axially aligned with said brush head. ### Claim 3 (depends on 1) The rotatable brush recited in claim 1, further comprising locking means by which to hold said brush head and said handle one above the other when said handle is rotated to said folded position lying below said brush head. ### Claim 4 (depends on 3) The rotatable brush recited in claim 3, wherein said locking means includes a catch formed on said brush head, said handle moving into detachable mating engagement with said catch when said handle is rotated to said folded position lying below said brush head. ### Claim 5 (depends on 4) The rotatable brush recited in claim 4, wherein said handle has a locking rib formed thereon and said brush head has a locking cavity formed therein, said locking rib being removably received within said locking cavity so that said handle moves into said detachable mating engagement with said catch when said handle is rotated to said folded position lying below said brush head. ### Claim 6 (depends on 5) The rotatable brush recited in claim 5, wherein said catch formed on the brush head includes at least one locking edge located at one side of said locking cavity, said at least one locking edge projecting into said locking cavity, and said handle moving into said detachable mating engagement with said at least one locking edge when said handle is rotated to said folded position below said brush head and said locking rib is removably received within said locking cavity. ### Claim 7 (depends on 5) The rotatable brush recited in claim 5, wherein said catch formed on said brush head includes a pair of locking edges located at opposite sides of said locking cavity, said pair of locking edges projecting into said locking cavity, and said handle moving into said detachable mating engagement with said pair of locking edges when said handle is rotated to said folded position below said brush head and said locking rib is removable received within said locking cavity. ### Claim 8 (depends on 5) The rotatable brush recited in claim 5, wherein said locking means also includes at least one locking groove formed in said handle adjacent said locking rib, said at least one locking groove of said handle snapping into said detachable mating engagement with said catch when said handle is rotated to said folded position and said locking rib is removably received within the locking cavity formed in said brush head. ### Claim 9 (depends on 5) The rotatable brush recited in claim 5, wherein said locking means also includes a pair of locking grooves formed in said handle at opposite sides of said locking rib, said pair of locking grooves snapping into said detachable mating engagement with said catch when said handle is rotated to said folded position and said locking rib is removably received within the locking cavity formed in said brush head. ### Claim 10 (depends on 5) The rotatable brush recited in claim 5, wherein each of said brush head and said handle has a top and a bottom, said locking cavity being formed at the bottom of said brush head and said locking rib being formed at the bottom of said handle so that said locking cavity and said locking rib are disposed in opposite facing alignment when said handle is rotated to said folded position. ### Claim 11 (depends on 1) The rotatable brush recited in claim 1, wherein said handle has a hollow fluid chamber, said brush further comprising a spray pump detachably connected to said handle and communicating with said hollow fluid chamber thereof. ### Claim 12 (depends on 11) The rotatable brush recited in claim 11, wherein said spray pump includes a pump head and a spray tube extending from said pump head and being removably received within the hollow fluid chamber of said hollow handle. ### Claim 13 (depends on 12) The rotatable brush recited in claim 12, wherein said handle has an open end and a first threaded coupler extending therearound and the pump head of said spray pump has a second threaded coupler extending therearound, said first and second couplers being rotated into mating engagement with one another, whereby said spray pump is detachably connected to said handle. ### Claim 14 A brush, comprising: a brush head having a set of bristles projecting therefrom to brush a contact surface; a handle pivotally connected to said brush head to be held in the hand of a user to manipulate said brush head over the contact surface, said handle having a hollow fluid chamber extending therethrough; a spray pump being detachably connected to said handle and communicating with said hollow fluid chamber thereof; a hinge by which said handle is pivotally connected to said brush head so that said handle is rotatable relative to said brush head between an unfolded position lying end-to-end and axially aligned with said brush head and a folded position lying below said brush head; a first lock by which to hold said handle in said unfolded position lying end-to-end and axially aligned with said brush head; and a second lock by which to detachably connect said brush head to said handle one above the other when said handle is rotated to said folded position lying below said brush head. ### Claim 15 (depends on 14) The brush recited in claim 14, wherein said first lock includes first and second locking lips located at respective opposing ends of said brush head and said handle, said locking lips being mated together to hold said handle in said unfolded position. ### Claim 16 (depends on 14) The brush recited in claim 14, wherein said second lock includes a locking groove formed on said handle and a catch formed on said brush head, said locking groove snapping into detachable mating engagement with said catch when said handle is rotated to said folded position lying below said brush head.
