Description

Technical Field

[0001] This utility model relates to the field of hair styling technology, and in particular to an automatic hair curling device with air supply capability. Background Technology

[0002] To adapt to different occasions, people wear different clothes to better shape their image and boost their confidence. Hairstyle is an important part of personal image. Currently, there are two main ways to style a hairstyle: one is through a professional hairstyling salon, and the other is for the user to do it themselves using professional tools. The former has the advantage of achieving the desired style, but the disadvantage is that it takes more time, and is generally suitable for important occasions. The latter has the advantage of saving time, but the disadvantage is that the user needs to prepare various different tools, and is generally suitable for everyday needs. In daily life, these everyday needs are more frequent; therefore, hairstyling devices have become important tools for people.

[0003] Existing hair styling devices, such as curling irons, typically heat hair by direct contact with a heating element. While this softens the hair for easier styling, the direct contact with the heating element can burn the hair and damage its quality. Furthermore, the long cooling time after use makes them difficult to store, negatively impacting the user experience. Utility Model Content

[0051] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0052] like Figures 1-16 As shown, this utility model provides an embodiment of an automatic hair curling device with air supply capability.

[0053] The automatic hair curling device with air supply includes a housing 1 with a main body 10 and a handle cover 11 that mates with the main body 10 to form a storage cavity (not shown in the attached figure). The handle cover 11 has an air inlet 12 communicating with the storage cavity, which generates airflow when the air supply component 7 is working. The automatic hair curling device also includes a heating component 4, a curling component, a rotating component, an air supply component 7, and a control circuit board 3 that controls the operation of the heating component 4, the curling component, and the rotating component. The control circuit board 3 is connected to an external power source via a rotating tail (not shown in the attached figure) to supply power to the control circuit board 3. The control circuit board 3 is located in the housing 1 and mates with the housing 1 to form the storage cavity. The housing 1 can be injection molded.

[0054] The heating component 4 includes a heat-conducting pipe 40 sealed at one end and a heat-conducting component 41 disposed within the heat-conducting pipe 40, as well as an electric heating component (not shown in the figure) that is thermally connected to the heat-conducting component 41. The other end of the heat-conducting pipe 40 is connected to the fixing base 2. The heat-conducting pipe 40 is provided with a heating cavity 401, and both the heat-conducting component 41 and the electric heating component are disposed within the heating cavity 401.

[0055] The hair curling assembly includes a hair curling tube 5 fitted onto a heat-conducting pipe 40. One end of the hair curling tube 5 is rotatably connected to a fixed base 2. A first gap 54 is provided between the hair curling tube 5 and the heat-conducting pipe 40. The hair curling tube 5 allows the hair to contact the surface of the heat-conducting pipe 40 through the first gap 54, thereby achieving dispersed heating of the hair. The rotating assembly includes a rotary motor 60 and a transmission mechanism 6 connecting the rotary motor 60 and the hair curling tube 5. The transmission mechanism 6 converts the rotation of the rotary motor 60 into the rotation of the hair curling tube 5. The transmission mechanism 6 includes a driving gear 61 located on the rotating shaft of the rotary motor and a driven gear disk 62 meshing with the driving gear 61. The driven gear disk 62 includes a gear hole 622 with transmission teeth 621 meshing with the driving gear 61. The end of the hair curling tube 5 is fixed to the driven gear disk 62, and a bearing 63 is provided between the hair curling tube 5 and the fixed base 2. The air supply assembly 7 includes a fan 72 and a fan motor 71 connected to the fan 72, and a first air duct 8 that delivers the airflow generated by the fan 72 to the first gap 54 through the fixed base 2 and the heat pipe 40. Under the control of the control circuit board 3, the fan 72 inputs air from the fixed base 2 into the heat pipe 40 through the first air duct 8, and outputs air from the heat pipe 40 and the fixed base 2 to the first gap 54.

[0056] The air inlet of the first air duct 8 is connected to the receiving cavity. The first air outlet 81 of the first air duct 8 is located between the heat-conducting pipe 40 and the fixing base 2, and can be discharged from the first gap 54. When the control circuit board 3 controls the fan 72 to work on the heating component 4, that is, when the air supply component 7 works during styling, hot air is output from the first gap 54. The hot air can flow along the surface of the heat-conducting pipe 40 in the heating component 4, and can reheat the hair in the first gap 54. The airflow heating can be more uniform, and can soften the hair faster to achieve the styling. At the same time, the hot air can carry away the heat on the surface of the hair that is in direct contact with the heat-conducting pipe 40. In this way, the temperature during styling is not significantly reduced, which would affect the softening of the hair, and the hair that is in direct contact with the heat-conducting pipe 40 is not overheated and damaged. When the control circuit board 3 controls the fan 72 to work after the heating component 4 stops, the airflow passes through the heat pipe 40 in the heating component 4, which can cool the inside of the heating component 4, such as the internal heat-conducting component 41 and the inner wall of the heat pipe 40. At the same time, when the airflow passes through the outside of the heating component 4, such as the outer surface of the heat pipe 40, it can cool the heating component 4 again, thus accelerating the cooling speed of the heating component 4. This allows the automatic hair curling device to be quickly stored after use, improving the user experience.

[0057] The first air duct 8 includes a through hole 21 provided in the fixed base 2 and a first air groove 2202 provided between the heat-conducting pipe 40 and the contact surface of the fixed base 2. The through hole 21 is connected to the receiving cavity. One end of the first air groove 2202 is connected to the through hole 21 through the heat-conducting pipe 40, and the other end is connected to the first gap 54. That is, the first air outlet 81 of the first air duct 8 is connected to the first gap 54 through the gap 56 formed between the heat-conducting pipe 40 and the mounting hole 533. That is, the air inlet end of the first air groove 2202 is connected to the heat-conducting pipe 40. The air outlet end of the first air groove 2202 is the same as the first air outlet 81 of the first air duct 8. This allows the air to cool the hair located in the first gap 54 during styling, achieving rapid styling. At the same time, it can also control the temperature of the heat-conducting pipe 40 during operation. The fixed base 2 includes a bracket end 20 for fixing the rotary motor 60 and a fixed end 22 for fixing the heat pipe 40 and the curling tube 5. The fixed end 22 is provided with a fixed step, which includes a vertical surface 223, a first fixed surface 220 and a second fixed surface 221 with multiple first protrusions 2201 in the circumferential direction, and a limiting ring 222. The second fixed surface 221 is provided with multiple third protrusions 2211. The second fixed surface 221 cooperates with the bearing 63. The limiting ring 222 limits the position of the bearing 63. The third protrusions 2211 form a third joint, which can reduce the mating surface with the bearing 63 and can also be well installed even with reduced machining accuracy. When the heat pipe 40 is fitted onto the first fixed surface 220, a first air groove 2202 is formed between adjacent first protrusions 2201. The air inlet end of the first air groove 2202 is connected to the heat pipe 40. A first air outlet 81 is provided between the vertical surface 223 and the end face of the heat pipe 40. The first air outlet 81 is connected to the other end of the first air groove 2202. That is to say, the first air groove 2202 is formed by a first groove (not shown in the figure) formed between adjacent first protrusions 2201. When the fixed end 22 is engaged with the hair curler 5, the first groove forms the first air groove 2202. One end of the first air groove 2202 is located inside the heat pipe 40 and is connected to the through hole 21. The other end of the first air groove 2202, that is, the first air outlet 81, is located between the end of the heat pipe 40 and the vertical surface 223.

[0058] In this embodiment, there are two heat-conducting components 41. Each heat-conducting component 41 includes a planar heat-conducting plate 410 and two arc-shaped heat dissipation plates 411 connected to the planar heat-conducting plate 410. The two arc-shaped heat dissipation plates 411 are provided with a slot 412 on the side away from the planar heat-conducting plate 410. The two arc-shaped heat dissipation plates 411 respectively contact the inner wall surface of the heat-conducting pipe 40 to form a first chamber 414 communicating with the through hole 21. When there are two heat-conducting components 41, the heat-generating component is located between the two planar heat-conducting plates 410. The slot 412 can be used to adjust the tightness of the fit between the arc-shaped heat dissipation plate 411 and the heat-conducting pipe 40, thereby improving the heat conduction efficiency.

[0059] Two baffles 413 are provided between the two planar heat-conducting plates 410 to form a fixed cavity 43 for mounting the heating element. The side of the fixed cavity 43 has a guide groove 44 communicating with the through hole 21. The guide groove 44 and the heat-conducting pipe 40 form a second chamber. The through hole 21 communicates with two first chambers 414 and one second chamber. When the fan 72 generates airflow through the structure formed by the heat-conducting component 41 within the heat-conducting pipe 40, it can reduce airflow disturbance within the heat-conducting pipe 40 and increase the airflow discharge speed. The area of ​​the first air outlet 81 is smaller than the area of ​​the through hole 21, which can increase the airflow speed at the first air outlet 81. When heating, the airflow is at a high temperature, allowing for secondary heating of the heating element and effective control of the temperature within the heat-conducting pipe 40. When heating stops, it can quickly reduce the temperature of the heat-conducting pipe 40.

[0060] When curling hair, the drive gear 61 in the transmission mechanism 6 drives the driven gear disk 62 to rotate. The curling tube 5 connected to the driven gear disk 62 is rotatably connected to the fixed base 2 through the bearing 63. The curling tube 5 rotates around the heat-conducting pipe 40, so that the hair can come into contact with the heat-conducting pipe 40. When the heat-conducting pipe 40 heats up, it can soften the hair. Cooling can be used to set the style when different styles are applied.

[0061] The air supply assembly 7 also includes a second air duct 9 that delivers the airflow generated by the fan 72 to the first gap 54 via the transmission mechanism 6 and the curling tube 5. The second air outlet 91 of the second air duct 9 communicates with the first gap 54 through the gap 56 formed between the heat-conducting pipe 40 and the mounting hole 533. The second air outlet 91 is positioned opposite to the first air outlet 81, and the airflows from the first air outlet 81 and the second air outlet 91 are opposite each other. Since the airflow from the second air duct 9 reaches the second air outlet 91 directly without passing through the curling tube 5 and mixes with the airflow from the first air outlet 81 before entering the first gap 54, when the heating component 4 is heating softened hair, the room-temperature airflow from the second air duct 9 can cool the softened hair, achieving a rapid styling effect. When the heating component 4 stops working, the air supply assembly 7 can also cooperate with the first air duct 8 through the second air duct 9 to cool the inside and outside of the heating component 4, accelerating the cooling speed. After use, the user can quickly store the product, improving the user experience.

[0062] The second air duct 9 includes a second air groove 532 disposed between the bearing 63 and the hair curler 5, and an air duct chamber 534 formed by the end face of the hair curler 5 and the transmission mechanism 6 communicating with the gear hole 622. That is, the mounting end 53 of the hair curler 5 is provided with a mounting cavity 530, and the second air groove 532 includes a plurality of second protrusions 531 disposed in the mounting cavity 530. A second groove (not shown in the figure) is formed between adjacent second protrusions 531. The second groove extends from the opening of the mounting cavity 530 to the mounting hole 533. When the mounting cavity 530 cooperates with the bearing 63, the second groove forms a second air groove 532 between the bearing 63 and the wall of the mounting cavity 530. The second air groove 532 communicates with the mounting hole 533.

[0063] The hair curler 5 has a mounting cavity 530 that mates with the bearing 63 and a mounting hole 533 at the bottom of the mounting cavity 530. A second air groove 532 is provided between the wall of the mounting cavity 530 and the bearing 63. One end of the second air groove 532 communicates with the gear hole 622, and the other end connects to the mounting hole 533 along the surface of the bearing 63. The air outlet of the second air groove 532 communicates with the first gap 54 through a gap 56 formed between the heat-conducting pipe 40 and the mounting hole 533. The second air outlet 91 corresponds to the first air outlet 81. In other words, the air inlet of the second air groove 532 communicates with the gear hole 622, the second air groove 532 connects to the mounting hole 533 along the surface of the bearing 63, and the air outlet of the second air groove 532 communicates with the first gap 54 through a gap 56 formed between the heat-conducting pipe 40 and the mounting hole 533. After assembly, there is a certain gap 56 between the outer side of the heat-conducting pipe 40 and the mounting hole 533. One end of the gap 56 is connected to the second air outlet 91 and the first air outlet 81, and the other end of the gap 56 is connected to the first gap 54.

[0064] The side of the hair curler 5 is provided with a hair curling groove 51, a hair curling cavity 50 and a hair curling opening 52 provided on the side wall of the hair curling cavity 50. The end of the hair curler 5 is provided with a hair curling hole 55, which is connected to the hair curling cavity 50, the hair curling groove 51 and the hair curling opening 52.

[0065] Based on the above implementation, this utility model also proposes another embodiment. The automatic hair curling device further includes an outer cylinder 101 sleeved on the hair curling tube 5. A second gap 103 is provided between the hair curling tube 5 and the outer cylinder 101. The first gap 54 and the second gap 103 are connected in the circumferential direction. The end and side of the outer cylinder 101 are respectively provided with an outer cylinder chamber 104 and an outer cylinder notch 102. The outer cylinder notch 102 is connected to the outer cylinder side hole 106 in the length direction. The outer cylinder side hole 106 forms two arc-shaped protrusions 105 at the end of the outer cylinder 101 to converge the outer cylinder notch 102.

[0066] As needed, the end of the heat pipe 40 is provided with a distributor 42, which has a distribution groove 421 and a guide slope 422 on one side.

[0067] After styling is complete, the fan motor 71 controls the fan 72 via the control circuit board 3. The airflow generated by the fan 72 passes through the first air duct 8, which consists of the through hole 21, the heat pipe 40, and the first air groove 2202 between the heat pipe 40 and the mounting base 2, to expel heat from inside the heat pipe 40. Simultaneously, the airflow passes through the second air duct 9 to deliver room-temperature air to the second air outlet 91, where it mixes with the hot air from the first air outlet 81 and is cooled. The cooled air then passes through the gap 56 formed between the heat pipe 40 and the mounting hole 533 into the first gap 54. When the heat pipe 40 is at a high temperature, the airflow passing through the first air duct 8 is also at a high temperature. By mixing with the room-temperature airflow from the second air outlet 91, the airflow's temperature decreases, and it interacts with the hair, preventing damage to the hair from high temperatures. When the hair temperature leaving the heat pipe 40 is higher than the airflow temperature, the airflow acts as a temperature reducer. When the hair temperature leaving the heat pipe 40 is lower than the airflow temperature, the airflow provides secondary heating to the hair, resulting in more even heating and faster softening of the hair. Once the styling is complete, the internal temperature of the heat pipe 40 can be reduced through the first air duct, while the ambient temperature airflow delivered through the second air duct reduces the surface temperature of the heat pipe 40. This allows the temperature of the heat pipe to be quickly reduced after the hairstyle is styled, making it easy to store quickly.

[0068] When in use, the hot airflow discharged from the first air duct 8 mixes with the room temperature airflow discharged from the second air outlet 91 of the second air duct 9 and reaches the hair in the first gap 54 for heating. The low temperature hot airflow can reheat the hair that has been heated by the heat pipe 40. Because the hot airflow heating can make the styled hair more evenly heated, it avoids the secondary heating that would cause the hair temperature to be too high and affect the hair quality.
