Description

[0001] This application claims priority to Korean Patent Application No. 10-2021-0092956, filed on July 15, 2021, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0002] The present invention relates to a hair curler head capable of automatically curling a user's hair by blow-drying, and a hair styling device having the same. Background Technology

[0003] Hair styling devices are typically beauty tools used to style a user's hair to create aesthetically pleasing looks, such as curls or waves to the user's preferences. Examples of hair styling devices include curling irons and heated styling brushes.

[0004] In recent years, a hair styling device has been proposed and used that automatically wraps and curls the hair around the head by blowing air along the surface of the curled head and drawing the hair in through an aerodynamic phenomenon called the "wall effect." This type of hair styling device uses air to attract and surround the hair, thus creating a style without excessive heat damage. Moreover, since it does not require the use of a bristle brush, the hair can slide off the head without tangling when the styling is complete.

[0005] In this type of hair styling device, the even flow of appropriate airflow along the direction of the curling head surface is the main factor affecting the curling performance, and various attempts are being made to improve the curling performance of hair through this point. Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] The present invention addresses the aforementioned problems and aims to provide a curling head for hair curling that, through a simple structure, evenly directs airflow along the surface of the curling head, thereby improving the curling performance of the hair, and a hair styling device having the same.

[0035] Hereinafter, embodiments of the hair curling head and hair styling device having the present invention will be described in detail with reference to the accompanying drawings. In the process of describing with reference to the drawings, the same or corresponding structural elements are given the same reference numerals, and repeated descriptions thereof will be omitted.

[0036] Figure 1 This is a perspective view of a hair curling head according to an embodiment of the present invention. Figure 2 for Figure 1 The diagram shown is a partial exploded 3D view of a curling iron for curly hair. In addition, Figure 3 for Figure 2 A three-dimensional view of the internal insert shown.

[0037] In this embodiment, the curling head 1 for curling hair is used in a hair styling device and is configured to be attached to the handle 2 (see reference) of the hair styling device. Figure 8 The function is as follows: the air generated by the operation of the fan unit built into the handle 2 is ejected along the circumferential direction (surface direction) of the curling head 1, thereby curling the hair.

[0038] Reference Figures 1 to 3 The hair curling head 1 of this embodiment includes a hair curling head body 10, a plurality of slots 20 and an internal insert 30.

[0039] The curling head body 10 has a cylindrical shape and an inlet 17 at one end for allowing air to flow in. A collar 14 can be formed in the inlet 17 of the curling head body 10, which can be detachably connected to the handle 2 of the hair styling device. The curling head body 10 can have a structure where one end (i.e., the fluid inlet) is partially open and the other end is closed.

[0040] The curling head body 10 may have a configuration in which multiple plates 11 are arranged sequentially along the circumferential direction. These plates 11 may have a curved panel configuration with a concave inner surface and a convex outer surface. According to this embodiment, a structure in which six curved panels are arranged sequentially and integrally form a cylindrical shape is illustrated (see reference). Figure 4 The number or curvature of the plates can be changed in a different way than in this embodiment.

[0041] Multiple slots 20 are formed along the longitudinal direction of the curling head body 10, and they are spaced apart at predetermined intervals along the circumferential direction of the curling head body 10. These slots 20 are formed between each plate portion 11 to provide space for the air blown inside the curling head body 10.

[0042] An internal insert 30 is inserted into the interior of the curling head body 10 to guide airflow, so that airflowing in through the inlet 17 of the curling head body 10 is expelled through the slot 20 and flows along the surface of the curling head body 10.

[0043] The internal insert 30 includes: a plurality of guide plates 31 arranged circumferentially; and a frame portion 33 for supporting the guide plates 31 to form air holes 32 between the plurality of guide plates 31. With this structure, the guide plates 31 and air holes 32 are alternately arranged circumferentially to form an internal insert 30 with an overall cylindrical shape. The diameter of the internal insert 30 is smaller than the diameter of the curling head body 10 so that it can be inserted into the curling head body 10, and can have a structure that is embedded and joined with the curling head body 10. An inlet 38 for allowing air to flow in is formed at one end of the internal insert 30, and the other end of the internal insert 30 has a closed structure.

[0044] Multiple guide ribs 35 may be formed on the outer surface of the guide plate 31. These guide ribs 35 may be arranged at predetermined intervals along the longitudinal direction of the inner insert 30. The multiple guide ribs 35 perform the function of dispersing and guiding the airflow that flows in through the air hole 32 into multiple airflows, thereby making the airflow uniform across the entire area of ​​the guide plate 31 and increasing the flow velocity.

[0045] The guide rib 35 may have a shape that is inclined at a predetermined angle relative to the longitudinal direction of the inner insert 30, thereby guiding the wind direction to the inclined direction of the guide rib 35.

[0046] On the other hand, the curling head body 10 may have multiple wing portions 15 for dispersing the air discharged through the slot 20 into multiple airflows, and the multiple wing portions 15 may be in an inclined shape at the outlet position of the slot 20. Similar to the guide ribs 35 of the guide plate 31, the multiple wing portions 15 also perform the function of homogenizing the airflow and increasing the flow rate.

[0047] Figure 4 for Figure 1 The image shows a cross-sectional view of a curling iron for curling hair.

[0048] Reference Figure 4 A slot 20 is formed between a relatively high curvature portion of one plate portion 11 and a relatively flat portion of another plate portion 11. In the following description, any two adjacent plate portions 11 that form the slot 20 will be referred to as the first plate portion 12 and the second plate portion 13, and the first plate portion 12 and the second plate portion 13 are arranged sequentially along the air discharge direction.

[0049] The guide plate 31 is configured to form a first air blowing space 41 and a second air blowing space 42 between the first plate portion 12 and the second plate portion 13, respectively.

[0050] The first blowing space 41 is formed between the guide plate 31 and the first plate portion 12, so that the air flowing in through the blowing hole 32 is blown out and discharged through the slot 20 between the first plate portion 12 and the second plate portion 13.

[0051] The second air-blowing space 42 is formed between the guide plate 31 and the second plate portion 13, and has a smaller space than the first air-blowing space 41. A portion of the air from the first air-blowing space 41 is blown through the second air-blowing space 42.

[0052] The guide plate 31 has a guide surface, the distance between which is narrower than ...

[0053] Figure 5 for Figure 1 The diagram shows the working state of a hair curler.

[0054] Reference Figure 5 The working process of the hair curling head 1 of this embodiment is described as follows: the air (wind) flowing in through the inlet 17 of the hair curling head body 10 is blown into the first blowing space 41 at the bottom of the first plate part 12 through the blowing hole 32 of the internal insert 30.

[0055] For reference Figure 5 The arrows indicate the wind direction. The airflow from the first airflow space 41 is expelled to the outside of the curling head body 10 through the slot 20 between the first plate portion 12 and the second plate portion 13. A portion of the airflow from the first airflow space 41, after being blown into the second airflow space 42, flows into the first airflow space 43 below the second plate portion 13 and merges with the airflow blown through the airflow hole 32. This airflow process occurs identically throughout the entire internal insert 30 and the curling head body 10.

[0056] A portion of the air blown through the air hole 32 into the space between the guide plate 31 and the plate portion 11 is discharged to the outside through the slot 20, while another portion of the air flows through the second air blowing space to form a circulating flow in the circumferential direction of the internal insert 30. As a result, the air discharged to the outside of the curling head body 10 can flow along the surface of the curling head body 10 with an appropriate airflow.

[0057] The air expelled through slot 20 forms a circumferential flow and combines with the air expelled through another slot 20 to form a flow along the surface of the curling head body 10. In this case, the air flowing across the surface is attracted to the curved surface of the curling head body 10 due to the Coanda Effect, and the hair around the curling head body 10 wraps around the surface of the curling head body 10 to form curls.

[0058] In this case, the wind blown by the guide ribs 35 and the wings 15 can make the airflow more uniform, increase the flow rate, and ultimately increase the hair inhalation effect.

[0059] Figure 6 This is a cross-sectional view of a curling head for curling hair according to another embodiment of the present invention. Figure 7 for Figure 6 The diagram shows the working state of a hair curler.

[0060] The hair curling head of this embodiment has a structure that is basically the same as that of the previous embodiment. The difference is that a guide protrusion 34 is also formed on the guide plate 31.

[0061] The guide protrusion 34 protrudes outward from the guide surface of the guide plate 31, and performs the function of guiding the air from the first air-blowing space 41 to the slot 20. The guide protrusion 34 may have a curved shape that protrudes outward, and may be formed at a predetermined interval from the position of the slot 20 to ensure that the air flows into the space of the second air-blowing space 42.

[0062] The air blowing process is the same as in the previous embodiment. The air blown into the first air blowing space 41 of the first plate 12 and guided by the guide protrusion 34 is discharged to the outside through the slot 20. A part of the air blows into the second air blowing space 42 and flows into the first air blowing space 43 of the second plate 13.

[0063] Figure 8 This is a front view of a hair styling device according to an embodiment of the present invention.

[0064] like Figure 8 As shown, the hair styling device of this embodiment includes a handle 2 and a curling head 1 that can be attached to the handle 2.

[0065] The handle 2 is configured to be held by the user and has a built-in fan unit for drawing in air to blow air. An inlet hole 3 is formed in the handle 2 for allowing air to flow in, and a power cable 5 can be connected to the handle 2. Furthermore, operation buttons 4 for user control can be provided on the outer surface of the handle 2.

[0066] The curling head 1 can be detachably mounted on the handle 2, in which case the collar 14 of the curling head body 10 is attached to the handle 2. As the fan unit built into the handle 2 operates, the blown air flows into the inlet 17 of the curling head body 10 and exits from the slot 20 of the curling head body 10 through the process described above.

[0067] The curling head 1 for curling hair can be prepared in various different types according to the diameter of the curling head body 10 or the number and shape of the slots 20. Users can choose the curling head 1 that suits their preferences and attach it to the handle 2 to operate the hair styling device.

[0068] According to an embodiment of the present invention, the structure that guides the direction of airflow from the internal insert disposed inside the curling head body to the outside of the slot has the effect of uniformly guiding airflow along the surface of the curling head.

[0069] This structure allows a portion of the air blown into the curling head body to be expelled to the outside through a narrow slot, while another portion circulates along the inner surface of the curling head body. This provides the advantage of allowing air to flow along the surface of the curling head body at an appropriate volume. Furthermore, the curling head body and internal insert, manufactured through a molding process, are assembled together, thus simplifying the manufacturing process.

[0070] Furthermore, according to embodiments of the present invention, multiple guide ribs and wings are formed in the internal insert and the curling head body to disperse the blown air, thereby having the advantage of improving hair curling performance by increasing the hair attraction effect.

[0071] The invention has been described above with reference to specific embodiments thereof. However, it is understood that those skilled in the art can modify and alter the invention in various ways without departing from the spirit and scope of the invention as set forth in the appended claims.
