Description

BACKGROUND

Conventional techniques for drying and straightening hair are time-consuming and at times technically demanding. A hair blow dryer is a device that is used to dry hair by blowing heated air over strands of hair causing the moisture on the hair to evaporate. Hair dryers can be difficult to use by an individual, especially a person that desires to straighten their hair while it dries. A flat iron is a device that is used to straighten hair and typically include two arms that extend outward in the same direction from a single base. The arms are typically positioned opposite one another and each contain a plate that can be heated to high temperatures. Hair is straightened by closing the heated plates around selected strands of hair and breaking with heat the hydrogen bonds that were responsible for the bends in the hair. The hair will thus remain straight until these hydrogen bonds are allowed to reform, usually from exposure to moisture. Flat irons known in the art are not effective on wet or damp hair and thus, require the time-consuming step of completely drying the strands of hair using, for example, a hair dryer prior to use.

The air duct receives air from the motorized fan and channels air out of at least one of the first and second opposed aims.

The heatable surface can deliver heat to strands of damp hair placed between the first and second opposed arms. The hinge element can rotate the first and second opposed arms in relation to the handle portion and in relation to each other. The heatable surface can be a flat aluminum plate or a flat ceramic plate. The handle portion and the first and second opposed arms can be coupled by the hinge element such that an angle between one of the first and second opposed arms and the handle portion is greater than 180 degrees. The air duct can also include a main air duct coupled to two opposing air ducts. The two opposing air ducts can be housed adjacent and on opposite sides of one of the heatable surface. The two opposing air ducts can include openings through which the air from the motorized fan is channeled onto strands of hair placed between the first and second opposed arms. The tool can also include a heating element housed in each of the first and second opposed arms that deliver heat to the heatable surfaces. At least one of the heating elements can be housed in close proximity to the air duct to deliver heat to the air as it passes through the air duct.

The heatable surface 430 can further be coupled to the cover element 420 and/or the top element 410.

FIG. 5 is an exploded view 500 of a hinge element 140. The hinge element 140 can couple to the handle portion 110 at one end and to the opposed arms 120, 130 at another. The hinge element 140 can bias the opposed arms 120, 130 into the open position such that hair can be easily placed between the surfaces of the opposed arms 120, 130. A user can compress the hinge element 140 such that the opposed arms 120, 130 are approach one another and hair is held between them such as on the heating surfaces. Further, the hinge element 140 can allow the upper arm 130 and the lower arm 120 to be placed on the same longitudinal axis as the handle portion 110 or, in the alternative, as shown in FIG. 1, the hinge element 140 can allow the arms 120, 130 to be positioned at various angles relative to the longitudinal axis of the handle portion 110.

The hinge element 140 can have an axis 510 in the shape of a cylinder. Each end of the axis 510 can extend longitudinally through opposing holes located in a hinge element of the lower fan base 221, a hinge element of the bottom element 311 and a hinge element of the top element 411 with each hinge element portion 221, 311, 411 positioned next to the other in layers, as illustrated in FIG. 5. Each hinge portion 221, 311, 411 can be circular-shaped in order to allow for maximum rotation around the axis 510. A screw 520 and a washer 525 can be used at the ends of the axis 510 to secure all hinge portions 221, 311, 411 in place.

In operation, the electrical cord 230 can provide electricity to the motorized fan 240. A user can turn the motorized fan 240 on and off by pressing one of the buttons 485. The operation of the motorized fan 240 can create a pressure gradient across the fan element 245, such that air can pass through the air intake openings 215 and filter 225, through the fan element 245, through the main air duct 270, into the two opposing air ducts 370 and out through the openings in the two opposing air ducts 375 and in the bracket element 345. The air can become heated as it passes through the two opposing air ducts 370 due to the close proximity of the two opposing air ducts 370 to the heating element 350. A user can also control the flow rate of the air by pressing one of the buttons 485 to increase the spin rate of the motorized fan 240 and another of the buttons 485 to decrease the spin rate. The air can have a drying effect on wet or damp hair when the lower distal portion is placed in close proximity to the hair.

Further, the electrical cord 230 can provide electricity to the heating elements 350, 450, which can then provide heat to the heatable surfaces 330, 430. A user can control the set point temperature of the heatable surfaces 330, 430 by pressing one of the buttons 485 to increase the set point temperature and another of the buttons to decrease the set point temperature. The control board 470 can be configured to deliver electricity to the heating elements 350, 450 until the set point temperature has been achieved. The heatable surfaces 330, 430 can be opposing portions, and can straighten wet or damp hair when heated and placed in a closed position by rotating the upper and lower arms 120, 130 toward one another about the axis 510 of the hinge 140 and placing strands of hair in between the heatable surfaces 330, 430.

In another variation, the motorized fan 240 can create a vacuum that pulls air into the openings in the two opposing air ducts 370, through the main air duct 270 and through the motorized fan element 245. The air can exit through the air intake openings 215. The air can become heated as it passes in close proximity to the heatable surfaces 330, 430 and the heating element 350. In operation, the motorized fan 240 can extract moisture off the wet or damp hair placed between the two opposing arms 120, 130, and such moisture can evaporate due to the decrease in air pressure caused by the vacuum created by the motorized fan 240 and the increase in temperature due to the heating element 350.
