TECHNICAL FIELD

[0002] This disclosure relates to hair brushes and particularly to heated hair iron brushes.

BACKGROUND

[0003] Typical hair styling devices such as non-heated hair brushes, hot hair brushes, hair irons, and combination blow dryer/hair brushes are ineffective for straightening and styling hair, especially thick hair. Such devices often include curved surfaces or bristles attached to curved surfaces which contact a user’s hair. These curved configurations often produce curve or curl in the hair, which is undesirable in scenarios where the user desires the hair to be straightened. Typical devices designed to straighten hair, such as paddle brushes or flat hair irons, are time consuming to use and lack the capability to both straighten and curve and/or curl hair using the same device. Such devices also lack the capability to separate, heat, and straighten hair simultaneously.

[0031] Described herein are devices for straightening and/or styling a user’s hair, including heated hair straightening iron brushes, also referred to as hair brushes. The disclosed hair brushes include a brush head having bristles, a heating element for heating the brush head and bristles, and a handle attached to the brush head for manipulating the brush head through hair. The brush head includes flat sides with bristles located on each side. For example, the hair brush may include four sides (i.e., a first side, second side, third side, and a fourth side). The flat shape of the sides of the brush head and the heat emitted by the brush body via the heating element efficiently straighten hair while the hair brush is pulled through the user’s hair. Further, the heated bristles attached to each side of the brush head pull the user’s hair into contact with the flat sides of the brush head and separate the user’s hair to more efficiently apply heat and straighten the hair. The user may also use bristles located on multiple sides of the brush body to style curves, curls, or angles into the user’s hair. In this manner the user may selectively straighten, curve, angle, or curl hair using the same hair brush.

The hair brush 100 may include a handle 102, an electrical connector 104, a brush body 106, first bristle inserts 108, second bristle inserts 110, bristles 112, an end cap 114, and a coupler 116. The hair brush may have one or more rows of bristles on each side of the hair brush. The hair brush may have 2, 3, 4, 5, or even 6 sides. Preferably, the hair brush has four sides. Each of the sides may have one row or more, two rows or more, or even three rows or more of bristles. Each side may have six rows or less, five rows or less, or four rows or less. Each row of bristles may be continuous bristles or groups of bristles. For example, the bristles may be a continuous line of bristles without spacing. Each row of bristles may be parallel to one another. Each bristle or group of bristles may be located next to an opposing bristle. The rows of bristles may have bristles or groups of bristles alternating one another. The bristles or groups of bristles may be spaced apart. The bristles may be plastic bristles, synthetic, fiber, nylon, boar bristles, horsehair, goat hair, or a combination thereof. The bristles may be a single bristle. The group of bristles may include about 5 bristles or more, about 10 bristles or more, about 15 bristles or more, about 20 bristles or more, or about 25 bristles or more each located in a tight proximity (e.g., a same hole). The group of bristles may include about 100 bristles or less, about 75 bristles or less, about 50 bristles or less, or about 40 bristles or less. Each row may include about 10 or more, about 12 or more, about 15 or more, about 17 or more, or about 20 or more bristles or groups of bristles. Each row may include about 50 or less, about 40 or less, about 30 or less, or about 25 or less bristles or groups of bristles. The amount and spacing for the bristles may depend upon a diameter of the bristles. For example, a brush having bristles with a diameter of about 1 mm may include about 20 bristles per row and bristles with a dimeter of about 0.01 mm may have about 200 bristles per row. The rows may point in different directions. The rows may be located an angle apart. The rows may be located about 45 degrees or more, about 60 degrees or more, or about 75 degrees or more apart (e.g., about 90 degrees).
