## Abstract

A hair grooming apparatus includes a vacuum mechanism and a vacuum chamber that is in fluid communication with the vacuum mechanism. The vacuum chamber includes a first opening positioned at a first end of the vacuum chamber with a first cross-sectional area and arranged to accommodate an insertion of a section of hair and a second opening positioned at a second and opposite end of the vacuum chamber. The vacuum chamber further includes a wall extending between the first and second openings and defining an interior bore. An air pocket is formed along a section of the interior bore extending from a first location located proximate to the first opening with a second cross-sectional area to a second location positioned between the first location and the second opening with a third cross-sectional area. The second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area.

## Claims

### Claim 1

A hair grooming apparatus comprising:
a vacuum mechanism;
a vacuum chamber in fluid communication with the vacuum mechanism, the vacuum mechanism comprising:
a first opening arranged to accommodate an insertion of a section of hair;
a second opening opposite the first opening; and
a wall extending from the first opening to the second opening and defining an interior bore along a length of the vacuum chamber; and
at least one vane extending inward from the wall into the interior bore.

### Claim 2 (depends on 1)

The hair grooming apparatus of claim 1, wherein the at least one vane further extends along the length of the vacuum chamber.

### Claim 3 (depends on 2)

The hair grooming apparatus of claim 2, wherein the at least one vane is a plurality of vanes extending inward from the wall into the interior bore and further extending along the length of the vacuum chamber.

### Claim 4 (depends on 3)

The hair grooming apparatus of claim 3, wherein the plurality of vanes are arranged equally along an inner circumference of the vacuum chamber.

### Claim 5 (depends on 1)

The hair grooming apparatus of claim 1, wherein a cross-sectional area of the vacuum chamber varies along the length of the vacuum chamber.

### Claim 6 (depends on 1)

The hair grooming apparatus of claim 1, further comprising:
a heated air chamber in fluid communication with the vacuum chamber;
a heating element; and
a fan configured to blow air over the heating element and into the heated air chamber.

### Claim 7 (depends on 6)

The hair grooming apparatus of claim 6, wherein the vacuum chamber, plurality of vanes, heated air chamber, heating element, and fan are positioned within a hand-held unit.
