The present invention relates to a hairstyling brush iron.
In general, when people, particularly women, design their desired hair styles by trimming strands of hair, the desired hair style is first set with a comb such as a roll brush and then fixed using heat applied from a hairdryer. In the conventional hair styling method, however, the comb and the hairdryer need to be used at the same time, which is cumbersome and inconvenient in use. In addition, a force should be applied to the strands of hair using the comb and the hairdryer in order to transform the strands of hair in a desired manner, which is a laborious work for a user. Further, hair professionals, such as hairdressers, perform such a laborious work repeatedly for a long time, which is quite an exhausting work.
An embodiment of the present invention provides a hairstyling brush iron which can set a user's desired hair style by applying heat to strands of hair and can protect the user's scalp against the heat.
According to an embodiment of the present invention, a hairstyling brush iron is provided, including an iron roll heated up to a high temperature, the iron roll hawing a plurality of grooves formed in a lengthwise direction along an outer surface of the iron roll, and a plurality of brushes coupled to the iron roll by coupling lower portions of the brushes to the grooves of the iron roll, wherein the brushes include one or more heat transfer units, the one or more heat transfer units have hollow holes formed in a vertical direction and coupled to the grooves of the iron roll, and one or more heat shield units coupled to the hollow holes and exposed through upper portions of the one or more heat transfer units.

A configuration of a hairstyling brush iron according to an embodiment of the present invention will now be described.
Referring to
The handle 110 is gripped by a user's hand when the hairstyling brush iron 100 is used. In order to apply power to the heaters 130 formed at one end of the handle 110, a power supply (not shown) is connected to the other end of the handle 110. Here, the outer portion of the handle 110 is formed of an electrical, thermal insulator for ensuring user's safety.
The handle 110 may include a switch 111 for controlling power on/off, a thermostat button 112 for adjusting the temperature of the brushes 140, and a display 113 indicating the current temperature of the brushes 140 through a light emitting diode (LED).
The iron roll 120 is coupled to an end of the handle 110. The iron roll 120 extends lengthwise from the handle 110 and is formed of a metal material. The iron roll 120 receives heat from the heaters 130 formed therein and transmits the heat to the brushes 140.
The iron roll 120 has a hole 121 lengthwise formed therein. In addition, since the heaters 130 are coupled to the hole 121, the heaters 130 are formed in a lengthwise direction of the iron roll 120, thereby uniformly applying heat to the iron roll 120.
The iron roll 120 has a substantially cylindrical shape, and includes first grooves 122 formed on its outer peripheral surface to be coupled to the brushes 140. The first grooves 122 are lengthwise formed along the lateral surface of the iron roll 120. In addition, the first grooves 122 have lower portions disposed within the iron roll 120 having larger diameters than upper portions disposed outside the iron roll 120, thereby preventing the brushes 140 coupled to the first grooves 122 from being dislodged. The first grooves 122 are radially formed along the periphery of the iron roll 120. This allows the brushes 140 coupled to the first grooves 122 to have a shape of a general roll brush.
A second groove 123 is formed at an end of the iron roll 120, and the fixing unit 150 is coupled to the second groove 123. The fixing unit 150 seals side portions of the first grooves 122, thereby fixing the brushes 140 coupled to the first grooves 122.
The heaters 130 are formed within the hole 121 of the iron roll 120. Since the heaters 130 are arranged in a lengthwise direction within the iron roll 120, they may apply a uniform amount of heat to the iron roll 120. The heaters 130 may be general heaters, for example, ceramic heaters, but not limited thereto.
The brushes 140 are formed in plurality to be coupled to the first grooves 122 of the iron roll 120. The brushes 140 are coupled to the first grooves 122 in a row. In addition, as many brushes 140 as the first grooves 122 are formed and coupled to the first grooves 122, respectively. Alternatively, fewer brushes 140 than the first grooves 122 may be formed, so that the brushes 140 may be formed only in some selected first grooves 122.
The brushes 140 receive heat from the iron roll 120 and transfer the heat to user's hair, thereby setting a hair style.
Each of the brushes 140 includes a heat transfer unit 141 coupled to each of the first grooves 122 of the iron roll 120, and a heat shield unit 142 formed within the heat transfer unit 141.
The heat transfer unit 141 is formed such that a diameter of its lower portion is greater than that of its upper portion so as to allow the lower portion to be coupled to the first grooves 122 of the iron roll 120. Since the heat transfer unit 141 receives heat from the iron roll 120 and transfers the same to the user's hair, it may be formed of a highly conductive metal. In addition, the heat transfer unit 141 has a hollow hole that vertically extends through the inside of the heat transfer unit 141. An upper portion of the heat shield unit 142 may be exposed through the hollow hole. In addition, the hollow hole of the heat transfer unit 141 may have a lower diameter greater than an upper diameter, which provides a stepped portion 141a. Therefore, if the heat shield unit 142 is coupled to the stepped portion 141a, it is possible to prevent the heat shield unit 141 from being dislodged. In addition, the heat transfer unit 141 has a lower outer peripheral surface having a predetermined thickness “d”. Thus, the thickness “d” of the heat transfer unit 141 makes adjacent heat transfer units 141 spaced apart from each other.
The heat shield unit 142 is positioned in the hollow hole of the heat transfer unit 141. In addition, the heat shield unit 142 is formed such that its lower diameter is greater than its upper diameter, providing for a stepped portion 142a. The stepped part 142a of the heat shield unit 142 is coupled to the stepped portion 141a of the heat transfer unit 141. The thickness “d” of the heat transfer unit 141 makes adjacent heat shield units 142 spaced apart from each other. Since a height of the heat shield unit 142 is greater than that of the heat transfer unit 141, the heat shield unit 142 protrudes further than a top portion of the heat transfer unit 141. In order to suppress heat transfer of the heat shield unit 141 and the iron roll 120, the heat shield unit 142 may be formed of a plastic material having low thermal conductivity. Specifically, the heat shield unit 142 may be formed of nylon or polybutylenterephthalate (PBT) having high thermal resistance. Therefore, it is possible to prevent the heat transfer unit 141 of high temperature from contacting user's scalp when the hairstyling brush iron 100 is used by the user, while allowing the heat shield unit 142 having relatively low heat conductivity to contact the user's scalp, thereby protecting the user's scalp.
The fixing unit 150 is coupled with the second groove 123 of the iron roll 120. A diameter of the fixing unit 150 is larger than that of the iron roll 120, thereby sealing side portions of the first grooves 122. Therefore, the fixing unit 150 prevents the brushes 140 of the iron roll 120 from being dislodged from the first grooves 122.
As described above, the hairstyling brush iron 100 according to the embodiment of the present invention includes the first grooves 122 formed in a lengthwise direction on the lateral surface of the iron roll 120, and the heat transfer units 141 coupled to the first grooves 122 to make the heat transfer units 141 contact user's hair, thereby facilitating hair style setting. In addition, the hairstyling brush iron 100 according to the embodiment of the present invention includes heat shield units 142 formed within the heat transfer units 141 and protruding further than top portions of the heat transfer units 141 to allow the heat shield units 142, rather than the heat transfer units 141, to contact the user's scalp, thereby protecting the user's scalp against heat of the heat transfer units 141.
Hereinafter, a configuration of a hairstyling brush iron according to another embodiment of the present invention will be described.
Referring to
The brushes 240 are coupled to the iron roll 120. The brushes 240 are coupled to first grooves 122 of the iron roll 120, thereby transferring heat to user's hair. In addition, upper portions of the brushes 240 contact user's scalp. Therefore, each of the brushes 240 is formed of a plastic material having low thermal conductivity, preferably nylon or PBT having high thermal resistance, thereby protecting the user's scalp against heat.
The brushes 240 include a plurality of brushes integrally formed in an array of rows. That is, each row of the integrally formed brushes 240 is coupled to each of the first grooves 122 of the iron roll 120. In addition, each of the brushes 240 includes a stepped portion 240a formed at its lower portion, so that the stepped portion 240a is coupled to each of the first grooves 122, thereby preventing the brushes 240 from being dislodged once they are coupled to the first grooves 122. Further, the brushes 240 may be coupled to the first grooves 122 all at once from one end of the iron roll 120 where a second groove 123 is formed. Therefore, the productivity of the hairstyling brush iron 200 can be increased.
As described above, the hairstyling brush iron 200 according to the embodiment of the present invention includes the brushes 240 integrally formed for each row to allow the brushes 240 to be coupled to the first grooves 122 of the iron roll 120 all at once, thereby increasing the productivity. In addition, in the hairstyling brush iron 200 according to the embodiment of the present invention, each of the brushes 240 is formed of nylon or polybutylenterephthalate (PBT) having high thermal resistance to reduce heat transfer, thereby protecting the user's scalp against heat of high temperature.
Hereinafter, a configuration of a hairstyling brush iron according to still another embodiment of the present invention will be described.
Referring to
The handle 310 is gripped by a user's hand and includes a power supply 111, a thermostat button 112, and a display 113. The handle 310 wraps around a surface of the iron roll 320, opposite to a surface to which the brushes 140 are coupled to thus prevent the iron roll 320 from being exposed, thereby protecting the user from the iron roll 320 of high temperature when the user uses the hairstyling brush iron 300.
The iron roll 320 is substantially plate-shaped and includes grooves 321 formed in a lengthwise direction of its one surface. Of course, the number of the grooves 321 formed in the iron roll 320 may vary according to the area of the iron roll 320. The brushes 140 are coupled to the grooves 321 and protrude toward the one surface of the iron roll 320. The iron roll 320 forms the brushes 140 in a shape of a general cushion brush.
The fixing unit 350 is coupled to an end of the iron roll 320. The fixing unit 350 seals the grooves 321 of the iron roll 320, thereby preventing the brushes 140 from being dislodged from the iron roll 320.
As described above, the hairstyling brush iron 300 according to the embodiment of the present invention includes heat transfer units 141 of the brushes 140 coupled to one surface of the plate-shaped iron roll 320, forming a cushion brush, thereby allowing the heat transfer units 141 to contact user's hair, which enables the user to easily set a hair style. In addition, the hairstyling brush iron 300 according to the embodiment of the present invention includes heat shield units 142 upwardly protruding from the brushes 140, thereby protecting the user's scalp against heat of the heat transfer units 141. In addition, although not shown, the hairstyling brush iron 300 according to the embodiment of the present invention may also include the brushes 240 used in the hairstyling brush iron 200, instead of the brushes 140. In this case, the productivity can further be increased.
Hereinafter, a configuration of a hairstyling brush iron according to still another embodiment of the present invention will be described.
