Description

Technical Field

[0001] This application relates to the field of hair styling equipment technology, and more particularly to a hair curling device. Background Technology

[0002] Curling irons in the present technology typically have multiple comb teeth on their surface. When curling the user's hair, these comb teeth help guide the hair along with the curling iron. To improve the curl's hold, air vents are usually provided on the body so that the hot air generated inside the curling iron can be blown onto the hair through the air vents for quick styling.

[0003] However, because the comb teeth need to be fixed to the body surface via independent base structures, and the air vents must be positioned away from these comb teeth and their bases, the air vents can only be located in the limited gap area between the comb tooth bases. This requires precise positioning of the comb tooth bases and meticulous planning of the air vent layout during manufacturing to ensure that the two do not interfere with each other on the limited surface area of ​​the body. This process significantly increases the manufacturing difficulty and cost of the curling iron's comb head structure; furthermore, the air vents occupy space on the surface of the curling iron body, compressing the actual space available for setting the comb tooth bases, thus limiting the number of comb teeth that can be installed on the body.

[0039] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0041] Reference Figures 1 to 6 As shown, this application embodiment provides a hair curling device, including a main body 1, an air supply component 2, and a plurality of comb teeth 3; the main body 1 has an installation cavity formed inside, and is provided with a plurality of ventilation holes 11 communicating with the installation cavity; the air supply component 2 is disposed in the installation cavity; the plurality of comb teeth 3 are correspondingly inserted into the plurality of ventilation holes 11; one end of the comb teeth 3 extends along the axial direction of the comb teeth 3 with an air guide groove 31, and the air guide groove 31 forms an air guide notch 32 on the side wall of the comb teeth 3; the end of the comb teeth 3 with the air guide groove 31 is inserted into the ventilation hole 11 so that the air guide groove 31 communicates with the installation cavity, and the air guide notch 32 is exposed on the outside of the main body 1; the airflow driven by the air supply component 2 can flow sequentially through the installation cavity, the air guide groove 31 and the air guide notch 32 to be blown out to the outside of the main body 1.

[0042] Specifically, the main body 1 can be a cylindrical hollow structure, and multiple ventilation holes 11 are provided on a set area on the side of the main body 1. The set area can be located on the side of the main body 1 near one end.

[0043] The ventilation hole 11 is located on the side of the main body 1 and penetrates the side wall of the main body 1, so that the ventilation hole 11 is connected to the mounting cavity; the air supply assembly 2 can be a turbine fan or a fan, which can drive air to be blown out from the ventilation hole 11 after the turbine fan or fan is started.

[0044] The comb teeth 3 can be a cylindrical structure, with one end of the comb teeth 3 recessed to form a groove structure as an air guide slot 31, so that the opening of the air guide slot 31 is at the end of the comb teeth 3; an opening can be provided on one side wall of the air guide slot 31 as an air guide notch 32, and the air guide notch 32 can be a rectangular or other shaped window; or the air guide slot 31 can be a through groove extending radially along the comb teeth 3, so that the air guide slot 31 forms a window structure on the side of the comb teeth 3, so that air can be blown out from the air guide slot 31.

[0045] The comb teeth 3 can be interference-fitted into the ventilation holes 11 to ensure stable installation of the comb teeth 3 within the ventilation holes 11, with the slot opening of the air guide groove 31 facing the mounting cavity. When the air supply assembly 2 is activated, the airflow from the mounting cavity and the air guide groove 31 flows to the air guide notch 32, and then is blown out radially from the air guide notch 32 along the comb teeth 3.

[0046] When the hair curling device provided in this application embodiment is used, the user wraps his / her hair around the main body 1, so that multiple comb teeth 3 are inserted into the user's hair. The air supply component 2 starts the air to flow towards the ventilation hole 11 in the installation cavity, so that the air enters the air guide groove 31 through the slot of the air guide groove 31, and then blows out through the air guide notch 32, so that the comb teeth 3 blow air out to the side to accelerate the styling of the user's hair.

[0047] The hair curling device provided in this application embodiment includes a main body 1, an air supply component 2, and a plurality of comb teeth 3. The inner wall of the main body 1 forms a mounting cavity and is provided with a plurality of ventilation holes 11 communicating with the mounting cavity. The air supply component 2 is disposed within the mounting cavity. One end of each comb tooth 3 is provided with an air guide groove 31, and the side of each comb tooth 3 is provided with an air guide notch 32. After the comb tooth 3 is inserted into the ventilation hole 11, the air guide groove 31 communicates with the mounting cavity, and the air guide notch 32 is exposed on the outside of the main body 1. The air supply component 2 can then drive air through the air guide groove 31 and the air guide notch 32 to blow it out to the outside of the main body 1. The comb teeth 3 are inserted into the ventilation holes 11, and the air guide groove 31 of the comb teeth 3 forms an airflow channel between the mounting cavity and the outside of the main body 1, allowing air in the mounting cavity to be blown out through the air guide groove 31 to the surface of the main body 1, thereby styling the hair curled on the main body 1. The comb teeth 3 are set in the ventilation holes 11, which improves the space utilization of the surface of the hair curling device; it eliminates the need to set an additional base structure on the main body 1 for installing the comb teeth 3, reducing the manufacturing difficulty of the hair curling device; and after the air supply component 2 is activated, the comb teeth 3 blow air out to the side, so that the hair wrapped on the main body 1 is evenly aired, so that the hair curling device has a better styling effect.

[0048] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the bottom of the air guide groove 31 is inclined toward the air guide notch 32 to form an air guide surface 311, so that the air guide surface 311 guides the airflow in the air guide groove 31 to flow toward the air guide notch 32.

[0049] With this configuration, the air guide surface 311 changes the direction of airflow, reduces the loss of kinetic energy during the process of airflow entering the air guide groove 31 and being blown out from the air guide notch 32, and improves the utilization rate of airflow by the curling device.

[0050] Specifically, the air guide surface 311 is the inclined bottom surface of the air guide groove 31. The air guide surface 311 is inclined towards the air guide notch 32. The included angle between the air guide surface 311 and the end face of the comb tooth 3 can be selected to be 30° to 60°, so that after the airflow flowing along the axial direction of the comb tooth 3 comes into contact with the air guide surface 311, the airflow flows along the air guide surface 311 and changes the flow direction of the airflow, so that the airflow is blown out from the air guide notch 32 along the air guide surface 311.

[0051] When the airflow in the air guide groove 31 flows along the air guide surface 311, the airflow direction is inclined relative to the main body 1 in the radial direction, so that the airflow blown out by the two adjacent comb teeth 3 is inclined in the direction away from the surface of the main body 1. Even if one air guide notch 32 is set towards another comb tooth 3, the airflow blown out from the air guide notch 32 will also flow in an inclined direction away from the main body 1, thereby reducing contact with the other comb tooth 3 and reducing the interference of adjacent comb teeth 3 on the airflow.

[0052] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, a plurality of ventilation holes 11 are spaced apart along the axial direction of the main body 1 to form a longitudinal array. The air guiding surfaces 311 of the plurality of comb teeth 3 in the longitudinal array are parallel to each other, and the opening direction of the air guiding notch 32 of each comb tooth 3 in the longitudinal array is inclined at a set angle to the circumference of the main body 1. A plurality of longitudinal arrays are arranged on the main body 1 along the circumference of the main body 1.

[0053] With this configuration, multiple ventilation holes 11 are evenly distributed on the main body 1. Each ventilation hole 11 is specifically arranged at intervals along the axial direction of the main body 1 to form a longitudinal array. The air guide surfaces 311 of each comb tooth 3 in the longitudinal array are parallel to each other so that the airflow blown out by each comb tooth 3 has the same degree of inclination in the radial direction of the main body 1.

[0054] The opening direction of the air guide notch 32 can be selected as the normal direction of the plane where the edge of the air guide notch 32 is located. This normal is inclined at a set angle to the circumference of the main body 1. The set angle can be selected as 45°, 30° or 60°. Of course, it can also be selected between 30° and 60°, as long as the flow direction of the airflow blown out from the air guide notch 32 is inclined relative to the circumference of the main body 1.

[0055] The opening direction of the air guide notch 32 is inclined relative to the circumference of the main body 1, so that the direction of the airflow blown out by the multiple comb teeth 3 in the longitudinal array is also inclined relative to the circumference of the main body 1. If the opening direction of the air guide notch 32 is set along the axial direction of the main body 1, the airflow blown out by the air guide notch 32 of one comb tooth 3 will come into contact with the adjacent comb tooth 3 and be disturbed, which will reduce the flow velocity of the airflow and cause the airflow of the comb tooth 3 to be obstructed. If the opening direction of the air guide notch 32 is set along the circumference of the main body 1, the airflow blown out by the multiple comb teeth 3 in the longitudinal array set along the circumference of the main body 1 will also easily interfere with each other, causing the airflow of the comb tooth 3 to be obstructed.

[0056] Furthermore, when the comb teeth 3 are provided with two air guide notches 32, the opening direction of the air guide notches 32 is set along the circumference or axial direction of the main body 1. The airflow directions of two adjacent comb teeth 3 are opposite and consume each other, resulting in a decrease in airflow velocity and poor airflow. However, when the opening direction of the air guide notches 32 is set at an angle to the circumference of the main body 1, the airflow directions of two adjacent comb teeth 3 in the axial and circumferential directions of the main body 1 can avoid each other, thus preventing adjacent comb teeth 3 from interfering with the airflow. Even if the comb teeth 3 are provided with two opposing air guide notches 32, the airflow of two adjacent comb teeth 3 can also avoid each other and avoid the problem of collision, thereby ensuring smooth airflow from multiple comb teeth 3.

[0057] The user rotates the main body 1, causing the evenly distributed comb teeth 3 on the main body 1 to grasp the hair and move it, thus making the hair curl around the outside of the main body 1. When the hair is curled around the outside of the main body 1, the comb teeth 3 on the multiple longitudinal arrays grasp the hair along the curling direction, and the airflow blown out by the multiple comb teeth 3 can evenly heat the hair curled around the main body 1.

[0058] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, two air guide notches 32 are provided on the sidewall of the comb teeth 3. The two air guide notches 32 are arranged opposite each other in the radial direction of the comb teeth 3, and the air guide surface 311 is located between the two air guide notches 32. Along the direction from one air guide notch 32 to the other air guide notch 32, the distance between the air guide surface 311 and one end face of the comb teeth 3 gradually increases, so that the air guide surface 311 guides the airflow in the air guide groove 31 to flow toward the two air guide notches 32 respectively.

[0059] With this configuration, the airflow in the air guide groove 31 is blown out through the two air guide notches 32, so that the comb teeth 3 can blow out hot air in two opposite directions. Moreover, the airflow blown out by the two air guide notches 32 is in the opposite direction to the tilt of the main body 1, so as to avoid the airflow collision between two adjacent comb teeth 3 and the loss of airflow energy, and ensure the airflow force of the comb teeth 3, and ensure the styling effect of the comb teeth 3 on the hair wrapped on the main body 1.

[0060] Specifically, the air guide groove 31 is a through groove along the radial direction of the comb tooth 3, thereby forming two air guide notches 32 on the side of the comb tooth 3. The two air guide notches 32 are arranged opposite each other along the radial direction of the comb tooth 3, so that the airflow in the air guide groove 31 can be blown out through the two air guide notches 32, so that the comb tooth 3 can have bidirectional airflow.

[0061] The bottom of the aforementioned air guide trough 31 is an inclined air guide surface 311. The air guide surface 311 is inclined toward an air guide notch 32. When the airflow in the air guide trough 31 moves to the air guide surface 311, the airflow is arranged along the air guide surface 311 toward the two air guide notches 32 respectively, so that when the airflow blows out from the two air guide notches 32, the airflow blown out from one air guide notch 32 is inclined in the radial direction of the main body 1 toward the direction away from the main body 1, and the airflow blown out from the other air guide notch 32 is inclined in the radial direction of the main body 1 toward the direction closer to the main body 1, so that the airflow blown out from the two adjacent comb teeth 3 can avoid each other and avoid the airflow blown out from the two adjacent comb teeth 3 colliding with each other and consuming the kinetic energy of the airflow.

[0062] Two adjacent comb teeth 3 can be selected as the first comb tooth and the second comb tooth. The air guide notches 32 of the first comb tooth and the second comb tooth are aligned in the circumferential direction of the main body 1. The air guide surfaces 311 of the first comb tooth and the second comb tooth are parallel. The airflow blown from the first comb tooth toward the second comb tooth 3 is inclined in a direction away from the main body 1, and the airflow blown from the second comb tooth 3 toward the first comb tooth is inclined in a direction closer to the main body 1, so that the airflow blown from the opposite sides of the first comb tooth and the second comb tooth avoids each other.

[0063] When the air guide notch 32 of the comb tooth 3 is inclined to the circumferential direction of the main body 1, the airflow blown out by the adjacent comb teeth 3 is also at different heights, so as to avoid the airflow blown out by other comb teeth 3 in the air outlet direction of the comb tooth 3 from affecting each other.

[0064] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, one end of the comb tooth 3 with the air guide groove 31 is snapped into connection with the ventilation hole 11.

[0065] With this configuration, the comb teeth 3 can be inserted into the ventilation holes 11 and snapped into place, simplifying the operation of installing the comb teeth 3 on the main body 1.

[0066] Specifically, the sidewall of the comb tooth 3 can be made into an elastic wall. When the comb tooth 3 is inserted into the ventilation hole 11, the elastic wall of the comb tooth 3 undergoes elastic deformation, causing the elastic wall of the comb tooth 3 to abut against the inner wall of the ventilation hole 11, so that the comb tooth 3 can be locked and fixed in the ventilation hole 11 after being inserted. Alternatively, the outer side of the end of the comb tooth 3 with the air guide groove 31 can be provided with a slot, and an elastic retaining ring can be embedded in the ventilation hole 11. After the comb tooth 3 is inserted into the ventilation hole 11, the elastic retaining ring is locked into the slot, so that the comb tooth 3 is locked and connected to the ventilation hole 11.

[0067] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the comb teeth 3 include a base 33 and two elastic arms 34. The two elastic arms 34 are connected to one end of the base 33 and are spaced apart. The space between the two elastic arms 34 forms an air guide groove 31. The adjacent sidewall edges of the two elastic arms 34 together form an air guide notch 32. The two elastic arms 34 pass through the ventilation hole 11 and abut against the inner wall of the ventilation hole 11.

[0068] With this configuration, the structure of the two elastic arms 34 combined with the base 33 is simple and has low manufacturing cost. The two elastic arms 34 abut against the inner wall of the ventilation hole 11, so that the two elastic arms 34 can be locked in the ventilation hole 11 under the action of friction. The elastic force of the two elastic arms 34 themselves can ensure the stability of the locking connection.

[0069] Specifically, the base 33 is a columnar structure, and two elastic arms 34 are connected to the end face of the base 33. The two elastic arms 34 are spaced apart in the radial direction of the base 33. The two elastic arms 34 can be parallel to each other, or they can be inclined to each other. The space between the two elastic arms 34 forms an air guide groove 31. The two elastic arms 34 are spaced apart at the radial edges of the base 33 so that the edges of the two elastic arms 34 form air guide notches 32. The air guide groove 31 formed by the two elastic arms 34 is a through groove along the radial direction of the comb teeth 3.

[0070] The furthest radial distance between the two elastic arms 34 at the base 33 is greater than the diameter of the vent hole 11, so that when the two elastic arms 34 are inserted into the vent hole 11, they undergo elastic deformation and move closer to each other, abutting against the inner wall of the vent hole 11 under the action of elastic force. When the two elastic arms 34 abut against the inner wall of the vent hole 11, there is a gap between the two elastic arms 34 to ensure that airflow can pass through the space between the two elastic arms 34 and blow out to the outside of the main body 1.

[0071] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the end of the elastic arm 34 away from the base 33 is provided with a snap-fit ​​protrusion 341, and the inner wall of the ventilation hole 11 is provided with two slots; when the comb teeth 3 snap-fit ​​with the ventilation hole 11, the two snap-fit ​​protrusions 341 are respectively snap-fitted and connected to the two slots.

[0072] With this configuration, the two slots have a positioning effect on the comb teeth 3. By adjusting the position of the two slots, the orientation of the air guide notch 32 of the comb teeth 3 can be adjusted, so that when multiple comb teeth 3 are engaged with the ventilation hole 11, the orientation of the air guide notch 32 of the comb teeth 3 can be conveniently positioned.

[0073] Specifically, the farthest distance between the two elastic arms 34 in the radial direction of the comb teeth 3 can be less than or equal to the diameter of the ventilation hole 11. After the two elastic arms 34 are provided with snap-fit ​​protrusions 341, the farthest distance between the two snap-fit ​​protrusions 341 in the radial direction of the comb teeth 3 is greater than the diameter of the ventilation hole 11. The two slots are arranged opposite to each other. After the two elastic arms 34 are inserted into the ventilation hole 11, the two snap-fit ​​protrusions 341 enter the two slots respectively, and under the action of the elastic force of the two elastic arms 34, the two snap-fit ​​protrusions 341 abut against the slot wall respectively.

[0074] By changing the position of the two slots around the ventilation hole 11, the orientation of the air guide notch 32 of the comb tooth 3 can be controlled. The slots can be set on the inner wall of the ventilation hole 11 near the end of the mounting cavity to facilitate the formation of slots on the inner wall of the ventilation hole 11.

[0075] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the main body 1 includes a handle portion 13 and a comb head 12;

[0076] The comb head 12 is connected to one end of the handle part 13. The handle part 13 and the comb head 12 are hollow inside and interconnected to form a mounting cavity. Multiple ventilation holes 11 are provided on the comb head 12, and the air supply component 2 is installed inside the handle part 13.

[0077] With this configuration, multiple comb teeth 3 are concentrated on the comb head 12, and the handle 13 is provided for the user to hold and rotate easily. The handle 13 is relatively long, and the air supply component 2 makes full use of the space inside the handle 13.

[0078] Specifically, the comb head 12 can be cylindrical, and the handle 13 is cylindrical. The diameter of the handle 13 is smaller than the diameter of the comb head 12. The comb head 12 can be threaded to the handle 13, or it can be snapped together with the handle 13, or they can be connected to each other by bolts.

[0079] Multiple ventilation holes 11 are provided on the comb head 12, and multiple comb teeth 3 are provided on the outside of the comb head 12. When the user turns the handle 13, the comb head 12 can be rotated. The user wraps the hair around the outside of the comb head 12, and the multiple comb teeth 3 are inserted into the user's hair. The air supply component 2 drives the airflow to blow out through the air guide notch 32 of the comb teeth 3, so that the hot air blown out by the comb teeth 3 can quickly style the hair wrapped on the main body 1.

[0080] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the inner wall of the comb head 12 is provided with a plurality of weight-reducing grooves, which extend along the axial direction of the main body 1 and are disposed between two adjacent ventilation holes 11 along the circumferential direction of the main body 1.

[0081] This design allows the weight-reducing groove to decrease the weight of the comb head 12, thereby reducing the overall weight of the curling device.

[0082] Specifically, the weight reduction groove can be a groove structure on the inner wall of the comb head 12. The weight reduction groove is set along the axial direction of the comb head 12 and avoids the ventilation hole 11 to prevent the weight reduction groove from affecting the structural strength of the connection between the comb teeth 3 and the ventilation hole 11.

[0083] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, in some embodiments, the air supply assembly 2 includes a fan 21, a heating wire 22, and a controller 23;

[0084] The fan 21 and heating wire 22 are electrically connected to the controller 23;

[0085] The blower 21 is fixedly installed inside the handle part 13. The end of the handle part 13 away from the comb head 12 is provided with an air inlet 14. The heating wire 22 is disposed between the blower 21 and the comb head 12. The controller 23 is disposed between the blower 21 and the air inlet 14.

[0086] With this configuration, the fan 21, heating wire 22 and controller 23 make full use of the space in the length direction of the handle 13; and after the fan 21 is started, the flowing air first passes through the controller 23 to reduce the temperature of the controller 23, and then is discharged from the air guide notch 32 after being heated by the heating wire 22, so as to improve the styling effect on the hair wrapped on the comb head 12.

[0087] Specifically, the blower 21 can be a turbine blower or a fan, the heating wire 22 can be an electric heating wire, and the controller 23 can be a chip or a circuit board. The controller 23 can be equipped with a power supply, and the chip or circuit board is electrically connected to the blower 21 or the heating wire 22 via wires. The end of the handle 13 away from the comb head 12 is provided with multiple through holes as air inlets 14. After the blower 21 is started, it drives air to enter the mounting cavity through the air inlets 14. The air flows through the controller 23, the blower 21 and the heating wire 22 in sequence and then flows out from the air guide notch 32.

[0088] When air flows in the mounting cavity, it can exchange heat with controller 23 when it flows through controller 23 to reduce the temperature of controller 23. When the air flows to heating wire 22, it exchanges heat with heating wire 22 to improve the stability of the air and cause hot air to be blown out of air guide notch 32.

[0089] In specific use, the hair curling device provided in this embodiment allows the user to hold the handle 13 and place their hair on the outside of the comb head 12, with multiple comb teeth 3 inserted into the hair on the outside of the comb head 12. The user rotates the handle 13 to rotate the comb head 12, causing the hair to curl around the comb head 12. The fan 21 is then activated, allowing air to enter the mounting cavity through the air inlet 14, be heated by the heating wire 22, and then blown out through the air guide notch 32. The heated air flows along the air guide surface 311 from the air guide groove 31, so that the heated air is blown out from the two air guide notches 32 on the comb teeth 3. The hair curled around the comb head 12 is heated and styled by the hot air blown out from the air guide notches 32.
