Description

Technical Field

[0001] This utility model belongs to the field of hair styling product technology, and in particular relates to a cool air curling iron. Background Technology

[0002] Curling irons, a common handheld hair styling device, are used to heat hair for curling. They mainly consist of a handle and a heating element. Traditional curling irons heat the hair at high temperatures using the heating element, then allow it to cool naturally at room temperature to set. This results in a slow setting process, requiring waiting, and the curls are prone to deforming during natural cooling, affecting the final result. Currently, some curling irons have an airflow mechanism that cools the curled hair, improving curling efficiency.

[0003] Chinese patent document CN222804010U discloses a curling iron, including a curling iron body and a connecting assembly. The curling iron body includes a tubular air outlet. The connecting assembly connects the tubular air outlet to the output end of the main unit. The tubular air outlet has several guide structures radially arranged on its outer periphery. Each guide structure has a radially penetrating, oblique air outlet. Both the guide structures and the oblique air outlets extend axially along the tubular air outlet. The airflow generated by the main unit passes through the connecting assembly and is blown out through the oblique air outlets. The guide structures direct the airflow from the oblique air outlets, causing the airflow to be blown out obliquely.

[0004] In the aforementioned patent document's technical solution, the airflow from the vent blows onto the hair, which helps improve the curling effect. However, regardless of whether the main unit generates cold or hot air, the airflow will be heated by the heat after passing through the curling section. Ultimately, the airflow blowing onto the hair from the vent will carry a certain amount of heat, making it impossible to quickly cool and set the heated hair, thus affecting the setting efficiency and final effect of the curling. Utility Model Content

[0005] The purpose of this invention is to provide a cool air curling iron that solves the problem that in existing curling irons, the air outlet is located on the curling part, and the airflow is hot air after passing through the curling part and then blown onto the hair from the air outlet. This results in poor cooling and setting effect of the curls, affecting the setting efficiency and effect of the curls.

[0006] When the hair is heated, the cold air flows towards the curling section. Uneven airflow causes different airflow rates in different areas of the heated hair, and temperature differences between the inner and outer surfaces of the heated hair. This results in poor curl setting and requires extending the heating time, thus reducing curling efficiency.

[0007] To achieve the above objectives, this utility model provides a cooling curling iron, including a curling section and a handle connected to one end of the curling section. The curling section is provided with a heating component. The outer surface of the handle near the end of the curling section has an air outlet circumferentially arranged, and the end away from the curling section has an air inlet. The handle has a mounting cavity inside, and a fan is installed in the mounting cavity. The fan draws in air through the air inlet and drives the air to flow out from the air outlet to cool the hair heated by the curling section.

[0008] Furthermore, the air outlet includes multiple rows of air outlet holes distributed along the circumference of the handle.

[0009] Furthermore, a baffle is fixedly provided inside the mounting cavity, and the baffle is provided with a plurality of baffles extending toward the air outlet, forming a flow diversion channel between adjacent baffles.

[0010] Furthermore, the air outlet includes multiple rows of air outlet holes distributed along the circumference of the handle; a baffle is provided on the inner side of each row of air outlet holes, and the baffle does not contact the air outlet hole or the inner wall of the mounting cavity.

[0011] Furthermore, each of the air outlets has a guide hole on its inner side, and the cross-section of the guide hole has a funnel-shaped structure.

[0012] Furthermore, a circuit board is also provided inside the mounting cavity. The circuit board is located between the fan and the baffle, and the top of the circuit board is lower than the lowest end of the air outlet. Multiple baffles on one side of the baffle are provided with a clearance structure at their bottom to avoid the circuit board.

[0013] Furthermore, the curling section also includes a heat-conducting cylinder and multiple heat-conducting protrusions. The heating component is located inside the heat-conducting cylinder, and the multiple heat-conducting protrusions are spaced apart on the outer surface of the heat-conducting cylinder.

[0014] Furthermore, the outer surface of the heat-conducting cylinder is also provided with anti-scalding comb teeth, which are circumferentially alternately distributed with heat-conducting protrusions on the outer surface of the heat-conducting cylinder. The radial length of the heat-conducting protrusions is less than the radial length of the anti-scalding comb teeth.

[0015] Furthermore, the anti-scalding comb teeth and the heat-conducting protrusions are respectively spaced apart along the axial direction of the heat-conducting cylinder; the distribution density of the heat-conducting protrusions along the axial direction of the heat-conducting cylinder is greater than the distribution density of the anti-scalding comb teeth along the axial direction of the heat-conducting cylinder.

[0016] Furthermore, the heat-conducting protrusions are integrally formed on the outer surface of the heat-conducting cylinder, and the material of the heat-conducting protrusions is metal.

[0017] Furthermore, the curling section also includes a heat-conducting cylinder, which includes two semi-cylindrical shells. A heating plane is formed on the side of the two semi-cylindrical shells that are close to each other, and a heating gap is formed between the two heating planes. The heating gap extends axially and penetrates to the end of the curling section away from the handle. The heating component is provided inside the two semi-cylindrical shells.

[0018] Furthermore, the two semi-cylindrical shells have anti-scalding comb teeth and heat-conducting protrusions alternately distributed on their arc-shaped outer surfaces in the circumferential direction, and the radial length of the heat-conducting protrusions is less than the radial length of the anti-scalding comb teeth.

[0019] The above-mentioned technical solutions of one or more of the cold air curling iron provided in this embodiment of the utility model have at least the following technical effects:

[0020] The user wraps the hair closest to the scalp around the curling iron on the side near the handle, and continues wrapping the remaining hair around other parts of the curling iron. After the hair is heated and shaped by the curling iron, the handle is rotated to move the heated, curled hair in the curling iron and wrap it around the air outlet area of ​​the handle. During the rotation of the handle to move the hair, some hair is heated in the curling iron, while some is cooled and set in the air outlet area after heating, allowing for simultaneous curling and cooling / setting. Alternatively, the heated curled hair can be wrapped around the air outlet area one or more times, and the handle is pulled towards the ends of the hair. As the handle is pulled downwards, all the wrapped hair passes through the air outlet to cool and set until the hair separates from the curling iron.

[0021] Because the air outlet and the heating components of the curling section are physically separated, the airflow driven by the fan does not pass through the heating components. The airflow temperature is lower and it acts directly on the surface of the curling hair, achieving the effect of instant hair styling. This improves the cooling and styling efficiency of the curling hair, shortens the overall styling time, and enhances the user experience.

[0022] In addition, as the user turns the handle to wrap their hair around the air outlet, the curling part moves simultaneously away from the user's head, effectively reducing the risk of burns caused by the heating element coming into contact with the skin. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0040] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0043] In one embodiment of the cool-air curling iron of this utility model, please refer to... Figures 1 to 12 A cooling curling iron includes a curling section 200 and a handle 100 connected to one end of the curling section 200. The curling section 200 is equipped with a heating element 210. The outer surface of the handle 100 near the curling section 200 is provided with an air outlet 110 in a circumferential direction, and the end away from the curling section 200 is provided with an air inlet 120. The handle 100 is provided with a mounting cavity 130, and a fan 140 is installed in the mounting cavity 130. The fan 140 draws in air through the air inlet 120 and drives the air to flow out from the air outlet 110 to cool the hair 300 that has been heated by the curling section 100.

[0044] Specifically, the user wraps the hair 300 near the scalp around the side of the curling section 200 closest to the handle 100. The remaining hair 300 continues to be wrapped around other parts of the curling section 200. After the hair 300 is heated and shaped by the curling section 200, the handle 100 is rotated to move the hair 300 heated and curled in the curling section 200 and wrap it around the air outlet 110 area of ​​the handle 100. During the process of rotating the handle 100 to move the hair 300, part of the hair 300 is heated in the curling section 200, and part of the heated hair is cooled and shaped in the air outlet 110 area, allowing for simultaneous curling and cooling / shaping. Alternatively, the heated hair can be wrapped around the air outlet 110 area one or more times, and the handle 100 is pulled towards the end of the hair 300. As the handle 100 is pulled downwards, all the wrapped hair 300 passes through the air outlet 110 for cooling and shaping until the hair 300 separates from the curling iron.

[0045] Because the air outlet 110 and the heating component 210 of the curling section are physically separated, the airflow driven by the fan 140 does not pass through the heating component 210. The airflow temperature is lower and it acts directly on the surface of the curling hair, achieving a 300-second styling effect. This improves the cooling and styling efficiency of the curling hair, shortens the overall styling time, and enhances the user experience.

[0046] In addition, as the user turns the handle 100 to wrap the hair 300 around the air outlet 110, the curling part 200 moves away from the user's head, effectively reducing the risk of burns caused by the heating element coming into contact with the skin.

[0047] Preferably, please refer to Figure 1 and Figure 7 The air inlet 120 is located on the end face of the handle 100 away from the curling section 200. The fan 140 is horizontally positioned along the axial direction of the mounting cavity 130, making the mounting cavity 130 an axially extending straight fluid channel. Specifically, the axis of the fan 140 is aligned with the axis of the mounting cavity 130, and the mounting cavity 130 directly serves as the air duct body, increasing airflow speed and flow rate. Furthermore, the horizontally positioned fan 140 distributes the center of gravity of the curling iron along the central axis of the handle 100, preventing vibration caused by the tilted placement of the fan 140.

[0048] For further details, please refer to... Figure 1 and Figure 2 The air outlet 110 includes multiple rows of air outlet holes 111 arranged around the circumference of the handle 100. Specifically, the multiple rows of air outlet holes 111 effectively increase the air outlet area and increase the airflow per unit time. The circumferential distribution of the air outlet holes 111 forms a ring-shaped airflow distribution. When the handle 100 is rotated to cool the curls, the airflow passes through the curls over a large area, avoiding cooling blind spots.

[0049] For further details, please refer to... Figures 5 to 8A baffle 150 is fixedly installed inside the mounting cavity 130. The baffle 150 has multiple baffles 151 extending toward the air outlet 110, and a diversion channel 152 is formed between adjacent baffles 151. Specifically, the baffles 151 are used to disperse the central high-speed airflow, avoid airflow concentration, make the airflow evenly distributed in the diversion channel 152, and balance the distribution of airflow velocity. This can reduce noise, and the airflow can be blown stably and evenly onto the hair 300 wrapped around the air outlet 110 area, increasing the cooling consistency of the hair 300 in different positions.

[0050] For further details, please refer to... Figures 5 to 8 The air outlet 110 includes multiple rows of air outlet holes 111 distributed along the circumference of the handle 100; each row of air outlet holes 111 has a baffle 151 on its inner side, and the baffle 151 does not contact the air outlet hole 111 or the inner wall of the mounting cavity 130. Specifically, one baffle 151 corresponds to the inner side of one row of air outlet holes 111, causing the airflow in the diversion channel 152 to flow along the inner wall of the baffle 151 to the air outlet hole 111, guiding the airflow towards the hair 300. The baffle 151 does not contact the air outlet hole 111 or the inner wall of the mounting cavity 130, preventing the airflow impact from generating large noise and vibration.

[0051] For further details, please refer to... Figure 5 Each air outlet 111 has a guide hole 112 on its inner side, and the cross-section of the guide hole 112 is a funnel-shaped structure. Specifically, the airflow is blown out of the air outlet along the guide hole 112, which increases the flow velocity and allows the airflow to penetrate the inner and outer surfaces of the hair 300. The funnel-shaped guide hole 112 further improves the uniformity of the airflow.

[0052] Preferably, please refer to Figure 3 The air outlet 111 has an outwardly expanding guide surface 113 at the end away from the mounting cavity 130, and the left and right adjacent air outlets 111 are staggered in the circumferential direction. Specifically, the guide surface 113 forms an inclined diffusion angle, so that the airflow is output at different angles along the hair 300, and the staggered air outlets 111 make the adjacent airflow coverage areas overlap, reducing the cooling blind zone.

[0053] For further details, please refer to... Figure 6 and Figure 7 The mounting cavity 130 also houses a circuit board 160, which is positioned between the fan 140 and the baffle 150. The top of the circuit board 160 is lower than the lowest point of the air outlet 110. Multiple baffles 151 on one side of the baffle 150 have a clearance structure 153 at their bottom to avoid the circuit board 160. Specifically, the airflow output from the fan 140 passes through the circuit board 160, isolating it from heat transfer and keeping it at a lower temperature during operation. Furthermore, the baffles 151 extend axially to one side of the circuit board 160, extending the length of the diversion channel 152, and the clearance structure 153 prevents the risk of mechanical interference.

[0054] For further details, please refer to... Figure 7 and Figure 9 The curling section 200 also includes a heat-conducting cylinder 220 and multiple heat-conducting protrusions 240. A heating component 210 is located inside the heat-conducting cylinder 220, and the multiple heat-conducting protrusions 240 are spaced apart on the outer surface of the heat-conducting cylinder 220. Specifically, the heat-conducting cylinder 220 is a one-piece molded cylinder. When the curling iron is working, the heating component 210 heats the heat-conducting cylinder 220, and the heat-conducting protrusions 240 heat up along with the heat-conducting cylinder 220 to heat the hair. When the user wraps the hair 300 around the outer surface of the heat-conducting cylinder 220, the heat-conducting protrusions 240 extend into the gaps between the hair 300, increasing the heat-conducting contact area of ​​the hair 300, shortening the heating and curling time of the hair 300, and improving styling efficiency. The heat-conducting protrusions can comb and position the hair, making it less likely to loosen when the hair 300 is heated, curled, and moved, improving the quality of the hair 300's heating and shaping.

[0055] For further details, please refer to... Figure 9 The outer surface of the heat-conducting cylinder 220 is also provided with anti-scalding comb teeth 230. The anti-scalding comb teeth 230 and heat-conducting protrusions 240 are circumferentially alternately distributed on the outer surface of the heat-conducting cylinder 220, and the radial length of the heat-conducting protrusions 240 is less than the radial length of the anti-scalding comb teeth 230. Specifically, the heat-conducting protrusions 240 and the anti-scalding comb teeth 230 cooperate to comb and position the hair 300. The radial length of the heat-conducting protrusions 240 is less than the radial length of the anti-scalding comb teeth 230, and the anti-scalding comb teeth 230 are used to protect the user from being burned by contact with the heat-conducting protrusions 240.

[0056] For further details, please refer to... Figure 7 The anti-scalding comb teeth 230 and the heat-conducting protrusions 240 are respectively arranged at intervals along the axial direction of the heat-conducting cylinder 220; the distribution density of the heat-conducting protrusions 240 along the axial direction of the heat-conducting cylinder 220 is greater than the distribution density of the anti-scalding comb teeth 230 along the axial direction of the heat-conducting cylinder. Specifically, this further increases the heat-conducting contact area of ​​the hair 300, and the high-density heat-conducting protrusions can transfer heat to the surface of the hair 300 more evenly and quickly, reducing the hair heating time and improving the styling efficiency and effect of curling. Preferably, multiple heat-conducting protrusions 240 are equidistantly arranged in the axial direction of the heat-conducting cylinder 220. Specifically, the equidistantly designed heat-conducting protrusions 240 ensure uniform heat transfer, making the hair 300 more evenly heated and reducing the risk of thermal stress concentration.

[0057] For further details, please refer to... Figure 9The heat-conducting protrusions 240 are integrally formed on the outer surface of the heat-conducting cylinder 220, and the material of the heat-conducting protrusions 240 is metal. Specifically, the integrally formed design of the heat-conducting protrusions 240 reduces assembly difficulty and increases structural strength. The metal material of both the heat-conducting protrusions 240 and the heat-conducting cylinder 220 is preferably aluminum. Aluminum's excellent thermal conductivity allows temperature to be quickly transferred to the heat-conducting cylinder 220 and the heat-conducting protrusions 240 when the heating component 210 heats up, ensuring that the heating time of both is not significantly different, guaranteeing stable heating of the hair 300, and also reducing the weight of the curling iron due to the lighter weight of aluminum. Preferably, the cross-section of the heat-conducting protrusions 240 is trapezoidal. Specifically, this increases the heat-contact area of ​​the hair 300 and reduces curling time.

[0058] Further, please refer to Figure 4 The free end of the heat-conducting protrusion 240 is provided with an inclined guide surface 241. Specifically, when winding hair, the guide surface 241 guides the hair 300 into the groove formed by the axially adjacent heat-conducting protrusions 240. Alternatively, the free end of the heat-conducting protrusion 240 is inverted V-shaped and has two inclined guide surfaces 241 to reduce friction and improve the efficiency of the hair 300 entering and winding around the curling section 200.

[0059] Please refer to another embodiment of this utility model of a cold-air curling iron. Figures 10 to 12 The curling section 200 includes a heat-conducting cylinder 220, which comprises two semi-cylindrical shells 221. A heating plane is formed on the side of the two semi-cylindrical shells 221 that are close to each other, and a heating gap 222 is formed between the two heating planes. The heating gap 222 extends axially and penetrates to the end of the curling section 200 away from the handle 100. A heating component 210 is provided inside each of the two semi-cylindrical shells 221.

[0060] Specifically, when the curling iron is in operation, the heating element 210 heats the semi-cylindrical housing 221, causing both semi-cylindrical housings 221 to heat up simultaneously. When curling hair, the user wraps the hair 300 around the outer surface of the heat-conducting cylinder 220 to heat and set the curls. When straightening hair, the user inserts the hair 300 into the heating gap 222 and pulls the handle 100 towards the ends to efficiently straighten the hair 300 within the heating gap 222. The curling iron has both curling and straightening functions, is easy to operate, and meets the needs of diverse styling.

[0061] Further, please refer to Figure 10Each of the two semi-cylindrical shells 221 has a heat insulation element 250 at the end furthest from the handle 100, and a heat insulation gap 251 connecting the two heat insulation elements 250 to the heating gap 222. Specifically, when straightening hair, the user passes the hair 300 through the heat insulation gap 251 into the heating gap 222, presses the two heat insulation elements 250 to ensure that the hair 300 is tightly attached to the plane of the two semi-cylindrical shells 221, and then moves the handle 100 synchronously to further enhance the straightening effect. The heat insulation element 250 effectively isolates the heating area, reducing the risk of burns to the user during curling or straightening operations.

[0062] For further details, please refer to... Figure 11 Each semi-cylindrical shell 221 has alternating heat-conducting protrusions 240 and anti-scalding comb teeth 230 on its arc-shaped outer surface. The radial length of the heat-conducting protrusions 240 is less than the radial length of the anti-scalding comb teeth 230. Specifically, when a user curls their hair, they wrap their hair 300 around the outer surface of the heat-conducting cylinder 220. The heat-conducting protrusions 240 extend into the gaps between the hair 300, increasing the heat-conducting contact area of ​​the hair 300 and improving curling efficiency. In addition, the radial length of the heat-conducting protrusions 240 is less than the radial length of the anti-scalding comb teeth 230, which protect the user from burns by contact with the heat-conducting protrusions 240.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
