Description

Technical Field

[0001] This application relates to the field of hair styling technology, and in particular to a hair curling iron with cooling and setting function. Background Technology

[0002] As people's living standards improve, hair styling devices are increasingly used in homes. These products typically include hair straighteners and curling irons. Hair straighteners are generally clip-shaped and often use a flat clamping design, resulting in poor curling effects. Although some hair straighteners have curved plates, the curvature is small, and the heating surface is usually a separate raised curved surface connected to the whole unit by a step, making it easy to snag hair during curling. Existing curling irons use a single curved body, winding hair by rotating a component, but lack a hair clamping function. This makes it difficult for existing hair straighteners to combine the functions of a hair straightener and a curling iron. Furthermore, since hair straighteners only require the clamping surface to style hair and do not need to be wound, existing hair straighteners usually lack a cool air setting function, making them functionally limited. Therefore, the market urgently needs a product that combines the functions of a hair straightener and a curling iron while also providing cooling and setting capabilities. When using cool air setting on hair straighteners, the hinged installation of the clamping plates and the arrangement of the internal cool air vents and ducts must also be considered. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems and provide a hair curling clip with cooling and setting function. The hair curling clip of this application has the functions of curling and styling hair and partial curling. The heating surface is continuous, making it easy to use when styling. It is also reasonably arranged and has the function of cooling and setting, which improves the setting efficiency and saves internal space.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A hair curling iron with cooling and shaping function includes a front shell, a rear shell, a heating element, a motor, fan blades, and a clamping plate. The front shell and the rear shell form an elliptical outer shell, and the inner cavity of the outer shell is an air guide cavity. A heating element with an arc-shaped contour that transitions continuously with the edge of the rear shell is installed on the front shell. The two ends of the heating element are flush with the front shell, so that a heating surface with half of its area being arc-shaped is formed on the front end face of the outer shell. The motor is connected to the fan blades and installed at the bottom of the air guide cavity. The housing forms an inwardly inclined air guide wall on the lower side of the fan blade. The air guide wall forms a mounting groove on the front side of the front housing. The clamping plate is hinged to the mounting groove. The rear housing has an air inlet on the side corresponding to the air guide wall. The rear housing has several vertically arranged air outlets in the area corresponding to the heating surface. A circuit board is installed between the motor and the air outlet in the air guide cavity. When the motor drives the fan blade to run, the airflow enters through the air inlet, flows through the circuit board, and is output through the air outlet.

[0006] In this application, the oval overall shell shape combined with the arc-shaped, continuous transition of the heating surface design enables the product to have the dual functions of curling and styling. The heating surface has no stepped breaks, effectively avoiding snagging the hair and ensuring smooth curling. The oval shell has a gentle curve, making it easier to operate during styling. In addition, the motor drives the fan blades, and the output airflow and the air guide cavity work together to allow cool air to quickly act directly on the surface of the styled hair through the air outlet, achieving a coordinated operation of heat shaping and cold setting, improving styling efficiency. At the same time, the air guide wall of the front shell guides the air intake and forms the hinge position of the clamp, making reasonable use of space. The air guide wall guides the airflow and forms the mounting position of the clamp. The installation of the clamp does not easily affect the airflow intake, effectively saving installation space. Moreover, the airflow simultaneously dissipates heat from the circuit board. The structure is reasonably arranged and makes efficient use of resources.

[0007] In one embodiment, the rear housing has two rows of air outlets forming an air outlet area on both sides of its arc-shaped profile.

[0008] In one embodiment, each of the air outlets is provided with a cross-shaped diversion rib.

[0009] In one embodiment, the device further includes a negative ion generator and an output line connected thereto. The negative ion generator is connected to the circuit board. The output line extends upwards. Symmetrically distributed limiting walls extend from the inner side of the front housing. The output line is engaged with the spacing formed by the limiting walls, and the negative ion release end of the output line is located in the middle of the front housing.

[0010] In one embodiment, the rear housing has an arc-shaped clearance groove in the area corresponding to the fan blade.

[0011] In one embodiment, the edge of the rear housing is provided with a plurality of protrusions near the heating element, and the protrusions are arc-shaped.

[0012] In one embodiment, the rear housing has buckles extending from both sides in the area of ​​the heating surface, and the front housing has fastening grooves on both sides, with locking blocks inside the fastening grooves. The buckles are inserted into the fastening grooves and fastened to the locking blocks.

[0013] In one embodiment, the front housing is equipped with a connecting seat, the middle of the connecting seat is separable, both ends of the connecting seat are provided with connecting blocks and form connecting grooves, the inner side of the heating element is provided with connecting ribs and inserted into the connecting grooves, the heating element is also provided with limiting ribs on both sides, and the edge of the connecting seat is inserted into the inner side of the limiting ribs.

[0014] In one embodiment, a spring is installed at the hinge point between the clamping plate and the front housing, and a locking buckle is also provided at the bottom of the housing to limit the rotation of the clamping plate.

[0015] In one embodiment, the side of the clamp that is in contact with the heating element is provided with a heat insulation sheet that matches the curvature of the heating element, and the outer side of the clamp is provided with heat dissipation holes that correspond to the position of the air outlet.

[0023] This application provides a hair curling iron with cooling and setting function to solve the technical problem that existing hair curlers are difficult to combine the functions of a hair curling iron and a curling iron. In addition, since the hair curling iron only needs to use the clamp surface to curl and style the hair and does not need to be wrapped, the existing hair curling iron does not have a cooling and setting function, which is a single function and affects the user experience.

[0024] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figures 1 to 7 This application provides a hair curling iron with cooling and shaping function, including a front housing 100, a rear housing 200, a heating element 300, a motor 400, a fan blade 410, and a clamping plate 20; the front housing 100 and the rear housing 200 form an elliptical outer shell 10, and the inner cavity of the outer shell 10 is an air guide cavity 11; a heating element 300 with an arc-shaped contour that transitions continuously with the edge of the rear housing 200 is installed on the front housing 100, and the two ends of the heating element 300 are flush with the front housing 100, so that a heating surface with half of its area being arc-shaped is formed on the front end surface of the outer shell 10; the motor 400 and the fan blade 410 are installed at the bottom of the air guide cavity 11, and the front housing 100... A guide wall 110 inclined inward is formed on the lower side of the blower assembly 400. The guide wall 110 forms a mounting groove 111 on the front side of the front housing 100. The clamping plate 20 is hinged to the mounting groove 111. An air inlet 210 is opened on the side of the rear housing 200 corresponding to the guide wall 110. The rear housing 200 has a plurality of vertically arranged air outlets 220 in the area corresponding to the heating surface. A circuit board 500 is installed in the air guide cavity 11 between the motor 400 and the air outlets 220. When the motor 400 drives the fan blade 410 to run, the airflow enters through the air inlet 210, flows through the circuit board 500 and is output through the air outlets 220.

[0026] Specifically, the front housing 100 and the rear housing 200 are both arc-shaped and interlocked to form an overall elliptical outer shell 10. The inner cavity of the outer shell 10 is a connected air guide cavity 11. The upper part of the front housing 100 forms a mounting position, where the heating element 300 is installed, with its two side edges close to the rear housing 200. The overall outline of the heating element 300 is adapted to the front housing 100 and transitions smoothly with the edge of the rear housing 200, thus forming an arc-shaped curved heating surface on the front end face of the outer shell 10. The connection of the heating element 300 is continuous with the outer shell 10. When using it, the user can perform partial curling or hair curling, making it smooth to use and multifunctional. The air guide cavity 11 is also arc-shaped, providing installation space for various components. The motor 400 and the fan blade 410 are located on the lower side of the air guide cavity 11 and are fixed to the front housing 100 by threaded connection. The front housing 100 is located below the motor 400 and the fan blade 410. An inwardly inclined air guide wall 110 is formed, and the opposite side of the air guide wall 110 is a plurality of air inlets 210 opened in the rear housing 200. The air guide wall 110 makes the air inlet side of the air inlets 210 form an inclined airflow direction. When the blower assembly 400 is running, the airflow can flow in better from the air inlets 210. When the motor 400 and the fan blades 410 are running, the airflow on the air inlet side is less likely to form a chaotic airflow. The air guide cavity 11 is located on the upper side of the blower assembly 400, where the circuit board 500 is installed. The rear housing 200 has vertically arranged air outlets 220 in the upper area corresponding to the heating surface. The air outlets 220 are vertically distributed in the area corresponding to the heating surface, so that when the user curls and perms the hair, cooling and styling can be performed accordingly. The position of the air outlets 220 is reasonable and corresponds to the heating surface, which improves the styling efficiency. At the same time, when the airflow is output, it flows through the circuit board 500, which also plays a role in heat dissipation of the circuit board 500, making efficient use of resources.

[0027] Furthermore, the rear housing 200 has two rows of air outlets 220 vertically distributed on both sides of its arc-shaped contour, forming an air outlet area. Each air outlet 220 contains a cross-shaped diversion rib 221. The rear housing 200 is arc-shaped, with the air outlet area located on both sides near the edge of the arc. The central protrusion 240 of the rear housing 200 is a closed surface. The air outlet area is composed of two rows of vertically distributed air outlets 220, and the diversion ribs 221 within the air outlets 220 are cross-shaped. This ensures that the airflow output from the motor 400 and fan blades 410 is more concentrated after passing through the diversion ribs 221, improving cooling and shaping efficiency. Furthermore, the airflow can be diverted to both sides through the air outlets 220 on both sides, ensuring a larger cooling and shaping area and further improving the cooling and shaping effect.

[0028] Furthermore, it also includes an output line 610 connected to the negative ion generator 600. The output line 610 extends upwards, and the inner side of the front housing 100 is provided with symmetrically distributed limiting walls 130. The output line 610 is engaged with the gap formed by the limiting walls, and the negative ion release end of the output line 610 is located in the middle of the front housing 100. The heating area of ​​the upper part of the front housing 100 is flat, with the front side used to install the heating element 300. The gap for engaging the output line 610 is formed in the middle of the limiting walls 130 extending in the air guide cavity 11 on the rear side, so that the negative ion release end of the output line 610 is located in the middle. Since the air outlet 220 of the rear housing 200 is located on both sides near the edge, the negative ions released by the output line 610 located in the middle can be fully dispersed to the air outlet area on the upper side of the air guide cavity 11, so that when the cold air is used for hair styling, the airflow can evenly output negative ions, which can care for the hair and reduce hair damage.

[0029] Furthermore, the rear housing 200 (410) is provided with an arc-shaped clearance groove 230 in the area corresponding to the fan blade 410. The motor 400 is fixed to the front housing 100 to drive the connected fan blade 410. The arc-shaped clearance groove 230 provided by the rear housing 200 in the area corresponding to the fan blade 410 can ensure that the fan blade 410 is not easily bumped during operation, thus avoiding affecting normal operation.

[0030] Furthermore, the rear housing 200 has several protrusions 240 spaced near the heating element 300 along its edge, and these protrusions 240 are arc-shaped. The multiple protrusions 240 spaced apart on both sides of the rear housing 200 in the corresponding heating surface areas form a flow-diverting zone. When curling hair, the arc-shaped protrusions 240 can divert the hair, making it more dispersed and more evenly styled. Combined with the air outlet 220 for cooling and styling, the hair can be cooled and styled more evenly through the flow diversion by the protrusions 240, ensuring a superior cooling and styling effect.

[0031] See further Figure 3 The rear housing 200 has buckles 250 extending from both sides in the area of ​​the heating surface. The front housing 100 has fastening grooves 120 on both sides, and fastening blocks 121 are provided in the fastening grooves 120. The buckles 250 are inserted into the fastening grooves 120 and fastened to the fastening blocks 121. The buckles 250 extending from both sides of the rear housing 200 are square with an opening in the middle. The fastening grooves 120 on both sides of the front housing 100 have fastening blocks 121. The upper surface of the fastening blocks 121 is inclined, making it easier to operate when the buckles 250 are fastened to the fastening blocks 121. By fastening the buckles 250 in the area of ​​the heating surface to the fastening blocks 121, the installation of the front housing 100 and the rear housing 200 in the area of ​​the heating surface is stable, without the need for other fixing structures that would affect the internal airflow.

[0032] For details, please refer to [link / reference]. Figures 4 to 6 The front housing 100 is equipped with a connecting seat 700. The middle part of the connecting seat 700 is separable. Both ends of the connecting seat 700 are provided with connecting blocks 710 and form connecting grooves 720. The inner side of the heating element 300 is provided with connecting ribs 310 and inserted into the connecting grooves 720. The heating element 300 is also provided with limiting ribs 320 on both sides. The edge of the connecting seat 700 is inserted into the inner side of the limiting ribs 320. The connecting slots 720 formed between the horizontally arranged connecting blocks 710 at both ends of the connecting seat 700 and the main body can be engaged with the L-shaped connecting ribs 310. In this embodiment, the connecting seat 700 is composed of a first connecting plate 730 and a second connecting plate 740 that are separately distributed vertically. When the heating element 300 is installed, the first connecting plate 730 and the second connecting plate 740 can be engaged with the connecting ribs 310 at both ends of the heating element 300 for quick and easy engagement and fixation. After engaging with the first connecting plate 730 and the second connecting plate 740 at both ends of the heating element 300, the limiting ribs 320 of the front housing 100 limit the two sides of the first connecting plate 730 and the second connecting plate 740, so that the heating element 300 is quickly fixed to the front housing 100 through the connecting seat 700, forming an arc-shaped contour that is continuous with the outer shell 10. While the heating element 300 is quickly engaged and fixed, the overall structure is simple and reasonable and easy to install.

[0033] Furthermore, a spring (not shown in the figure) is installed at the hinge position between the clamping plate 20 and the front housing 100. A locking buckle 12 is also provided at the bottom of the housing to limit the rotation of the clamping plate 20. A hinge wall 21 extends from the bottom of the clamping plate 20. The hinge wall 21 is hinged to the mounting groove 111 via a hinge shaft. One end of the spring is inserted into the mounting groove 111 of the front housing 100, and the other end abuts against the clamping plate 20, thereby making the clamping plate 20 elastic and capable of reciprocating rotation. The locking buckle 12 at the bottom of the housing is rotatable. The locking buckle 12 forms a locking block 13 in the mounting groove 111. The lower side of the hinge wall 21 forms a groove that cooperates with the locking block 13. When the locking 12 is moved, causing the locking block 13 to move to the lower side corresponding to the groove, the swing of the clamping plate 20 is limited and cannot be unfolded, so that the clamping plate 20 can fit against the heating element 300 for easy storage.

[0034] See Figure 7The clamping plate 20 has a heat insulation sheet 22 on the side that fits against the heating element 300, which matches the curvature of the heating element 300. The outer side of the clamping plate 20 has heat dissipation holes 23 corresponding to the positions of the air outlet 220. The side of the clamping plate 20 facing the heating surface has a curved heat insulation sheet 22 that matches the heating surface, facilitating clamping and heating. After use, it works with the heat dissipation holes 23 to dissipate heat, improving heat dissipation efficiency. Furthermore, the position and shape of the heat dissipation holes 23 are consistent with the distribution of the air outlet 220, resulting in a uniform appearance and improving the overall aesthetics of the product.
