[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] See Figures 1 to 3 The hair curling device shown in one embodiment of the present invention includes a handle portion 1 having a receiving space 11, an airflow generating component 2 disposed in the receiving space 11, and a hair curling component 3, wherein the airflow generating component 2 is used to generate airflow.

[0030] The handle portion 1 includes a handle housing 12 defining a receiving space 11. The handle housing 12 is a hollow cylindrical structure. A handle base 13 is connected to the bottom of the handle housing 12. The handle base 13 is fixedly connected to the handle housing 12 by an interference fit, but is not limited thereto. Other methods include threaded fixing, clamp fixing, and the like. An air inlet 121 is formed on the handle housing 12 for admitting outside air into the handle housing 12. Specifically, the air inlet 121 is formed near the handle base 13 on the handle housing 12 and includes a plurality of first air inlets that are evenly and regularly arranged. Air enters the receiving space 11 through the air inlet 121. The handle housing 12 is provided with a recessed hole (not shown), which is a rectangular structure. A display screen 14 for displaying the parameters of the curling device is installed in the recessed hole. When the curling device is used, the temperature and other parameters of the device can be understood through the display screen 14. The handle housing 12 is provided with a small hole (not shown) above the recessed hole. A button 15 for turning the curling device on and off is installed in the small hole.

[0031] Furthermore, a second air inlet 131 is formed on the handle bottom shell 13. This second air inlet comprises a plurality of evenly and regularly arranged second air inlets to increase the amount of air entering the receiving space 11. A protruding portion 132 is formed at the center of the handle bottom shell 13, extending outward from the surface of the handle bottom shell 13. This protruding portion 132 surrounds a through hole 133 that extends through the handle bottom shell 13, thereby connecting the receiving space 11 to the outside world.

[0032] The handle portion 1 also includes an inner wire housing 16 disposed within the receiving space 11. This inner wire housing 16 has a conical structure, with one end of the inner wire housing 16 surrounding the outer side of the protruding portion 132 to secure the inner wire housing 16 within the receiving space 11. To allow airflow through the inner wire housing 16 and into the upper portion of the receiving space 11, the inner wire housing 16 is formed with at least one vent 161, with four vents 161 provided. The inner wire housing 16 is used to accommodate the wires (not shown) that power the curling device. The structure of the inner wire housing 16 satisfies the requirements for accommodating the wires while maximizing airflow, thereby increasing the efficiency of the airflow generating assembly 2. One end of the wire extends through the curling device through the through hole 133 to connect to the external mains electricity supply, while the other end is connected to a component within the curling device that requires power.

[0033] The handle 1 further includes a heating element 17 disposed within the receiving space 11. In the height direction of the curling device, the heating element 17 is located above the air inlet 121, thereby heating the airflow entering the receiving space 11. In this embodiment, the heating element 17 is located above the airflow generating assembly 2, thereby heating the airflow generated by the airflow generating assembly 2.

[0034] The hair curling device further comprises a control assembly located in the receiving space 11 , and the control assembly is signal-connected to components such as the airflow generating assembly 2 and the heating element 17 .

[0035] The airflow generating assembly 2 includes a motor and a second impeller connected to the motor. The second impeller and the motor are integrated or separated. In this embodiment, the second impeller and the motor are integrated to reduce the volume and increase the speed of the generated airflow.

[0036] A support frame 18 is also provided in the handle housing 12 to support the airflow generating assembly 2. The support frame 18 is located in the receiving space 11 and is in close contact with the inner wall of the handle housing 12. The handle housing 12 protrudes outward from the inner wall near the top to form an annular step 122. The support frame 18 is held between the wire inner housing 16 and the annular step 122. The wire inner housing 16 and the annular step 122 limit the height movement of the support frame 18. The support frame 18 is a hollow structure. The airflow generating assembly 2 and the control assembly are located in the support frame 18. A convex ring 181 is formed by protruding outward from the inner wall of the support frame 18. The airflow generating assembly 2 is partially held between the convex ring 181 and the annular step 122. The convex ring 181 and the annular step 122 limit the height movement of the airflow generating assembly 2, thereby fixing the airflow generating assembly 2 in the receiving space 11. The inner wall of the support frame 18 has a receiving groove 182, which is concave inward from the inner wall of the support frame 18. There are two receiving grooves 182, which are arranged opposite to each other. The control component includes a PBC board 19, and both sides of the PBC board 19 are clamped in the two receiving grooves 182. The PBC board 19 is located on the wire inner shell 16, thereby fixing the PBC board 19 in the receiving space 11.

[0037] The curling assembly 3 includes a reel 31 connected to the receiving space 11, a first impeller 32 fixedly mounted within the reel 31, and a curling housing 33 having an opening 331. The reel 31 and first impeller 32 are rotatable relative to the handle 1, and the curling housing 33 is fixedly connected to the handle 1. Airflow flows from the receiving space 11 into the reel 31, driving the first impeller 32 to rotate. The rotation of the first impeller 32 drives the reel 31 to rotate. The airflow drives the first impeller 32 to rotate, generating a portion of airflow. For convenience, this portion of airflow merges with the airflow generated by the airflow generating assembly 2 to form a curling airflow. The reel 31 and first impeller 32 are rotatable relative to the handle 1, while the curling housing 33 is fixed relative to the handle 1.

[0038] Please combine Figure 4The curling housing 33 is disposed around the outer side of the reel 31, forming a gap between the curling housing 33 and the reel 31. Hair enters the gap through the opening 331, and the rotation of the reel 31 causes the hair to be wound around the reel 31. The curling housing 33 is provided with a base 332. Specifically, the base 332 and the curling housing 33 are integrally formed, but this is not limited to this. The curling housing 33 and the base 332 can be fixedly connected by screws or other means. The base 332 is provided with a groove 3321. In this embodiment, the groove 3321 extends through the base 332. In other embodiments, the groove 3321 may not extend through the base 332. The curling assembly 3 also includes a curling top shell 36 located on the top of the curling housing 33. The curling top shell 36 can be fixed to the curling housing 33 by means of threads, screws, etc.

[0039] Please combine Figure 5 The reel 31 is formed with an air outlet 311 for airflow. The air outlet 311 is composed of a plurality of air outlets evenly and regularly arranged on the reel 31. The curling airflow flows out of the reel 31 from the air outlet 311 and blows into the gap formed by the reel 31 and the curling housing 33. This airflow attracts the hair located at the opening 331 to the surface of the reel 31. The reel 31 has two moon-shaped hooks 312 at the top. As the reel 31 rotates, the moon-shaped hooks 312 further quickly hook the hair onto the reel 31, thereby increasing the amount of curled hair and the curling efficiency.

[0040] Please combine Figure 4The hair curling device further includes a rotating member fixedly connected to the curling shaft 31. The rotating member is rotatable relative to the handle portion 1 and is rotatably connected to the hair curling housing 33. Specifically, the rotating member is rotatably mounted on the base 332. The rotating member includes a rotating disk 341 and a connecting shaft 342 connected to the rotating disk 341. In this embodiment, to reduce size, the rotating disk 341 and the connecting shaft 342 can be integrally formed. The connecting shaft 342 is rotatably connected to the groove 3321. To reduce rotational friction between the connecting shaft 342 and the groove 3321 and improve rotational stability, a bearing 35 is disposed between the connecting shaft 342 and the groove 3321. The bearing 35 comprises a bearing outer shell (not numbered) connected to the groove 3321, a bearing inner shell (not numbered) connected to the connecting shaft 342, and a ball (not numbered) positioned between the bearing outer shell and the bearing inner shell. To reduce size, the bearing outer shell is secured to the groove 3321 by an interference fit, and the connecting shaft 342 is secured to the bearing inner shell by an interference fit. Of course, in other embodiments, the fixing methods for the bearing outer shell to the groove 3321 and the connecting shaft 342 to the bearing inner shell may include screws, clamps, or other methods, which are not described in detail here. In terms of the height of the curling device, the first impeller 32 is located above the base 332 and the rotating disk 341. In order to allow the airflow generated by the airflow generating assembly 2 to enter the scroll 31 as much as possible and drive the first impeller 32, at least one air hole (unnumbered) is formed on the base 332 and the turntable 341. In this embodiment, the number of air holes set on the turntable 341 is six, and the number of air holes set on the base 332 is four.

[0041] It should be noted that in this embodiment, a sensing component (not shown) is provided at the opening 331 of the curling housing 33, which is connected to the control component signal. When the sensing component senses that a bundle of hair has begun to be placed at the opening 331, the control component activates the heating element 17, thereby heating the airflow. As a result, the curling airflow flowing out of the reel 31 has a relatively high temperature of 100-200°C, styling the hair. The heating element 17 stops heating after 5-10 seconds, and the temperature of the curling airflow drops below 100°C, thereby achieving cold air styling. This method does not damage the hair. After styling the current bundle of hair, when the next bundle of hair is placed, the heating element 17 restarts the heated airflow, and the curling cycle continues.

[0042] The method of curling hair with the curling device is as follows: press the button 15 to start the curling device, and the airflow generating component 2 works to generate airflow. The airflow passes through the heating element 17, the base 332 and the turntable 341 from the receiving space 11 in sequence and enters the reel 31, thereby driving the first impeller 32 to rotate and forming a curling airflow. The rotation of the first impeller 32 drives the rotation of the reel 31, and the curling airflow flows from the reel 31 to the outside of the reel 31. A bunch of hair is placed at the opening 331, and the heating element 17 starts to heat. The curling airflow drives the hair to approach and adhere to the reel 31. The rotation of the reel 31 drives the hair to be wrapped around the reel 31, realizing wind-driven non-mechanical automatic curling. The hot air styling of the hair is completed after 5-10 seconds, and then the heating element 17 is turned off, and the curling airflow with a lowered temperature continues to shape the hair, thereby completing the curling.

[0043] While the curling airflow is high in temperature during the curling process, the presence of the curling housing 33 directs the airflow toward the gap between the curling housing 33 and the reel 31, preventing direct contact with the skin and preventing burns. This provides increased safety. Essential oils or other hair-care products can also be applied to the curling housing 33, providing hair care while curling. Furthermore, negative ions and water ions accompanying the airflow also provide hair care.

[0044] It should be noted that the present invention can replace reels with different outer diameters to produce curls of different sizes, and can also replace reels with different rotation directions to produce curls in different directions.

[0045] In summary, the curling device provided by the present invention has an airflow generating assembly for generating airflow, the airflow flows from the containing space into the reel and drives the first impeller to rotate, the first impeller rotates to drive the reel to rotate, thereby realizing automatic winding of the hair around the reel for curling. The airflow is used to drive the reel to rotate to curl the hair, and the problem of mechanical pinching of the hair will not occur. The hair is highly safe. The curls are shaped by the airflow without damaging the hair. The curling device has a simple structure and a high curling efficiency. By replacing reels with different outer diameters, curls of different sizes can be achieved. The hot air or cold air blown out from the curling device will not directly contact the skin, thus avoiding burns, and the operation is highly comfortable.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
