Description

Agent’s Ref: 14410.0020-00304HAIR STYLING DEVICE TECHNICAL FIELD

[0001] The disclosed embodiments generally relate to systems, devices, and methods for styling hair, and more particularly, for styling hair by simultaneously heating and cooling sections of hair using a heating element and a cooling element of a hair styling device.BACKGROUND

[0002] Hair styling devices may be used to style and curl hair. Many methods for curling hair require specific techniques to successfully create and maintain a curl. For example, to use a hair straightening device to curl hair, the user must twist the device at different angles so that the hair can cool on the edge of the straightening device. This method requires skill and practice to create a consistent curl throughout the hair. To use a curling iron to curl hair, the user must wrap sections of hair around the curling iron barrel, heat the hair, remove the barrel, and hold the curled section of hair while it cools. This method creates a consistently sized curl but lacks curl variety and requires that the user’s hair be straightened before curling. This method further creates inconsistent heat throughout the tress when a tress is double wrapped around the barrel of the curling iron. Other hair styling devices may create a curl by cooling hair as it passes through curved plates. However, such hair styling devices require specific techniques and changes in the orientation of the hair styling device while passing the device through a section of hair to create a curl. Such hair styling devices that require complicated techniques to create and maintain a curl are difficult for users to use and often create inconsistent or poorly shaped curls.

[0003] Therefore, to address these deficiencies in existing hair styling devices, solutions should be implemented to provide a hair styling device that can create consistent curls with a single pass of the hair styling device through a section of hair. Such solutionsAgent’s Ref: 14410.0020-00304 should vary the amount of curl in a section of hair based on, for example, changes in the temperature of the cooling path of the hair, the geometry of the hair styling device, the speed that the hair styling device is passed over a section of hair, and the temperature of the hot plates of the hair sty ling device. Such solutions should not require a user to create specific orientations or changes in orientations of the hair sty ling device as the user passes the device through a section of hair to create a curl. For example, such solutions should provide a hair styling device with specific internal geometries of heating and cooling elements that create a curl without manual bending of the hair at an angle by the user. Such hair sty ling devices should further heat a section of hair consistently until the section of hair enters a cooling radius, which may prevent a frizzing effect in the final hair style. These and other technological improvements and advantages are discussed below.SUMMARY

For example, after passing through the heating portion of body 125, the section of hair may passing over nozzle 320 for the application of cooling air and exit body 125 through exit portion 525. The cooling air distributed from nozzle 320 may further create and maintain a defined curl. As shown in Fig. 5, the path of hair between entrance portion 520 and exit portion 525 may be non-linear. For example, hair may enter body 125 through entrance portion 520 at a higher elevation along body 125 than exit potion 525. The non-linear path of hair through body 125 may allow the section of hair to be manipulated across angles to create a curl as the section of hair passes through body 125. Further, varying the level of heat applied to the section of hair through heating plate 315 and heating plate 515 and the level of cool air applied to the section of hair through nozzle 320 may alter the level and definition of curl in the section of hair. For example, providing colder air through nozzle 320 may create a tighter curl while providing warmer air through nozzle 320 may create a looser curl. As a section of hair passes through body 125, a first portion of the section of hair may be heated while a second portion of the section of hair may be cooled.

The section of hair may then pass over second nozzle 925. Second control valve 1125 may be in an open configuration, and cooling air may be distributed from second nozzle 925. The cooling air distributed from second nozzle 925 may further create and maintain a defined curl. A user may vary the level of heat applied to the section of hair through heating plate 515 and heating plate 1115 and the level of cool air applied to the section of hair through first nozzle 920 or second nozzle 925. Varying the heating and cooling levels may alter the level and definition of curl in the section of hair. For example, providing colder air through first nozzle 920 or second nozzle 925 may create a tighter curl while providing warmer air through first nozzle 920 or second nozzle 925 may create a looser curl.

[0126] In other embodiments, a section of hair may pass through hair styling device 600 such that the end of the section of hair extends from second side 970 of body 625. In such an embodiment, a user may manipulate rotation knob 805 such that second control valve 1125 is in a closed position and first control valve 1120 is in an open position. Allowing a user to open and close first nozzle 920 or second nozzle 925 may allow user to use hair styling device 600 in different orientations while still applying heat to the sections of hair before cooling air is applied to the sections of hair.Agent’s Ref: 14410.0020-00304
