Agitator for a surface treatment apparatus and a surface treatment apparatus having the same
An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.
1 . An agitator for a vacuum cleaner comprising:
an agitator body; and
a resiliently deformable flap extending outwardly from the agitator body, the resiliently deformable flap including:
a front face;
a rear face; and
one or more projections extending outwardly from the front face, wherein the one or more projections includes a raised portion that extends outwardly from the front face and a recessed portion that extends inwardly from the front face;
wherein the resiliently deformable flap includes a polyester layer and a silicone layer, the polyester layer forming the front face and the silicone layer forming at least a portion of the rear face.
2 . The agitator of claim 1 , further comprising a first bristle strip and/or row of tufts disposed adjacent to the first deformable flap.
3 . The agitator of claim 1 , wherein the one or more projections includes a first plurality of projections arranged in a first row.
4 . The agitator of claim 3 , wherein the one or more projections includes a second plurality of projections arranged in a second row.
5 . The agitator of claim 4 , wherein the first row and the second row are substantially parallel to each other.
6 . The agitator of claim 4 , wherein the first plurality of projections in the first row are offset left-to-right relative to the second plurality of projections in the second row.
7 . The agitator of claim 1 , wherein the one or more projections are formed only in the polyester layer.
8 . An agitator for a vacuum cleaner comprising:
an agitator body; and
a resiliently deformable flap extending outwardly from the agitator body, the resiliently deformable flap including:
a front face;
a rear face;
one or more projections extending outwardly from the front face, wherein the one or more projections includes a raised portion that extends outwardly from the front face and a recessed portion that extends inwardly from the front face; and
a facing layer coupled to a backing layer, the facing layer forming the front face and the backing layer forming the rear face.
9 . The agitator of claim 8 , wherein at least a portion of the facing layer is melted to at least partially form the one or more projections.
10 . The agitator of claim 9 , wherein the melted facing layer forms the one or more projections having a localized hardness.
11 . The agitator of claim 9 , wherein a portion of the melted facing layer flows away from the facing layer to form the raised portion and the recessed portion.
12 . The agitator of claim 9 , wherein only a portion of the facing layer is melted to form the one or more projections.
13 . An agitator for a vacuum cleaner comprising:
an agitator body; and
a resiliently deformable flap extending outwardly from the agitator body, the resiliently deformable flap including:
a front face;
a rear face;
one or more projections extending outwardly from the front face, wherein the one or more projections includes a raised portion that extends outwardly from the front face and a recessed portion that extends inwardly from the front face; and
a facing layer coupled to a backing layer by way of one or more intermediate layers, wherein at least a portion of the intermediate layer is melted to at least partially form the one or more projections.
14 . The agitator of claim 13 , wherein at least a portion of the facing layer is melted to form at least a portion of the one or more projections.
15 . The agitator of claim 3 , wherein the first row is disposed 1.75 mm+0.50/ −0.60 mm away a cleaning edge of the resiliently deformable flap.
16 . The agitator of claim 1 , wherein the one or more projections include a raised portion that extends outwardly from the front face having a generally annular shape.
17 . The agitator of claim 1 , wherein the one or more projections include a raised portion that extends outwardly from the front face having a generally annulus shape.
18 . The agitator of claim 17 , wherein the one or more projections have an outer diameter of annulus of 2.20 mm+/−0.30 mm.
19 . The agitator of claim 3 , wherein the first plurality of projections have a projection center to center distance of 5.00 mm.
