[0023] Reference Figure 1-Figure 5 According to an embodiment of a hair curling iron with adjustable comb teeth, the hair curling iron comprises a handle portion 11 and a heating portion 12 connected to the handle portion 11. A detachable power cord is also connected to the left end of the handle portion 11. The heating portion 12 comprises a heat-conducting sleeve 13 arranged at the right end of the handle portion 11. The heat-conducting sleeve 13 is made of metal to facilitate heat conduction.

[0024] A support sleeve 14 is also provided on the right side of the handle portion 11, and the support sleeve 14 is located in the heat-conducting sleeve 13, and a plurality of comb teeth 15 are provided on the outer curved surface of the support sleeve 14, and the comb teeth 15 extend to the outside of the heat-conducting sleeve 13, and a through hole for accommodating the comb teeth 15 is provided in the heat-conducting sleeve 13. A heating element for heating the heating portion 12 is provided in the handle portion 11, and the heating method of the heating element is not limited, including heating it through the heating wire connected to the heat-conducting sleeve 13, which is a prior art and will not be repeated here. The user can press the button on the handle portion 11 and the heating element to heat the heating portion 12, and the user can comb the hair and style it through the comb teeth 15.

[0025] In order to make the comb teeth 15 recyclable, so that the hair curling iron with adjustable comb teeth is easy to pack and carry, and to prevent the protruding comb teeth from breaking in the bag, the support sleeve 14 includes fixed arc plates 21 on the front and rear sides and a sliding arc plate 22 that slides up and down and is connected between the two fixed arc plates 21. The comb teeth 15 are arranged on the outer curved surface of the sliding arc plate 22, and also include a positioning mechanism 101 for controlling the two sliding arc plates 22 to move toward each other. The positioning mechanism 101 can control the two sliding arc plates 22 to approach each other, thereby retracting the comb teeth 15 into the through hole in the heat-conductive sleeve 13, so as to prevent the protruding comb teeth 15 from breaking when the hair curling iron with adjustable comb teeth is packed and carried.

[0026] In addition, a top cover 31 is provided at the end of the heat-conducting sleeve 13. In order to facilitate the disassembly and assembly of the top cover 31, a slot and an annular groove are provided on the inner side of the top cover 31. The heat-conducting sleeve 13 can be inserted into the annular groove, and the fixed arc plate 21 can be inserted into the slot. The top cover 31 is fixed to the heat-conducting sleeve 13 by friction, which is convenient for users to disassemble and assemble it.

[0027] In this embodiment, the positioning mechanism 101 includes a No. 1 spring 33 connected between the two sliding arc plates 22, and the No. 1 spring 33 tends to make the two sliding arc plates 22 approach each other. In addition, a rotating shaft 34 is rotatably connected to the right side of the handle portion 11, and a support plate 35 is fixed on the rotating shaft 34. The support plate 35 is located between the two sliding arc plates 22, and the support plate 35 and the No. 1 spring 33 are offset left and right. When the rotating shaft 34 rotates, the support plate 35 will abut against the sides of the two sliding arc plates 22 that are close to each other and stretch them apart. The distance between the two sliding arc plates 22 and the length of the comb teeth 15 extending outside the through hole depend on the angle of the rotating shaft 34 and the support plate 35.

[0028] In order to facilitate the user to control the angle of the support plate 35, a rotation groove is provided in the top cover 31 which runs through the left and right sides and is coaxial with the top cover 31. A control panel 36 is rotatably connected in the rotation groove. The control panel 36 is connected to the rotating shaft 34 through a connecting mechanism. The right side of the control panel 36 is integrally formed with a hand control panel 38 which is convenient for the user to twist. That is, the user can rotate the hand control panel 38 to rotate the rotating shaft 34 connected to the control panel 36 through the connecting mechanism to control the extension length of the comb teeth 15.

[0029] Since the top cover 31 can be disassembled, the connecting mechanism includes a boss 37 arranged at the left end of the control panel 36, and the right end face of the rotating shaft 34 can be inserted into the card of the boss 37, that is, when the top cover 31 is installed, the boss 37 can be inserted into the card to complete the connection.

[0030] In addition, in order to lock the extended length of the comb teeth 15, a locking mechanism for controlling the angle of the control plate 36 relative to the top cover 31 is also included. The locking mechanism includes two slide grooves 41 arranged in the outer curved surface of the top cover 31 and distributed up and down. A pressing plate 44 is connected to the slide groove 41 by sliding up and down through a No. 2 spring, and a hook plate 42 is connected to the bottom surface of the pressing plate 44. The hook plate 42 can enter the rotating groove, and with the axis of the control plate 36 as the center, a plurality of equal angles are arranged on the outer curved surface of the control plate 36 to adapt to the hook plate 42. The pressing plate 44 is provided with a positioning groove 43. When the pressing plate 44 is pressed inward, the hook plate 42 will leave the positioning groove 43. At this time, the control plate 36 can drive the rotating shaft 34 and the supporting plate 35 to rotate freely, and control the spacing between the two sliding arc plates 22 and the extended length of the comb teeth 15. When the user lets go, the pressing plate 44 will rebound under the action of the No. 2 spring, and make the hook plate 42 re-enter the rotating groove to lock the angle of the control plate 36 at this time, and lock the extended length of the comb teeth 15 at this time.

[0031] In the second embodiment of the hair curling iron with adjustable comb teeth, in order to facilitate users to care for their hair, it also includes an oil brushing ring 51, which is slidably connected to the outside of the heat-conducting sleeve 13 to the left and right, and a liquid storage tank 52 is arranged in the oil brushing ring 51. The liquid storage tank 52 can store liquids such as hair care oil, and an oil outlet hole 55 is arranged in the side of the liquid storage tank 52. When the oil brushing ring 51 slides left and right outside the heat-conducting sleeve 13, the hair care oil in the liquid storage tank 52 can be applied to the outside of the heat-conducting sleeve 13 through the oil outlet hole 55, so that the user can care for the hair by acting on the hair through the heat-conducting sleeve 13 and the comb teeth 15.

[0032] The oil brush ring 51 can be adsorbed on the left side of the top cover 31 through a permanent magnet to prevent random sliding, and an oil filling hole connected to the liquid storage tank 52 is provided in the outer side surface of the oil brush ring 51 for easy reuse.

[0033] In the second embodiment of the oil brushing ring 51, in order to apply oil evenly and avoid oil leakage through the oil outlet hole 55, the diameter of the oil outlet hole 55 is reduced. Under the action of liquid tension, the liquid in the liquid storage tank 52 will not directly flow out through the oil outlet hole 55. An oil brushing cotton ring 53 is provided in the inner curved surface of the oil brushing ring 51. The oil outlet hole 55 is opposite to the oil brushing cotton ring 53. The right side surface of the liquid storage tank 52 is connected to a pressure ring 54 through a No. 3 spring. The right side surface of the pressure ring 54 is fixed with a pressure plate extending to the right side of the oil brushing ring 51. The pressure ring 54 is located on the left side of the oil brushing cotton ring 53.

[0034] When the oil brush ring 51 is attached to the top cover 31, the pressure ring 54 will be at the leftmost side relative to the oil brush ring 51. At this time, the liquid in the liquid storage tank 52 will not flow out through the oil outlet hole 55 due to liquid tension. When the user pushes the oil brush ring 51 to the left, the pressure ring 54 moves to the right under the action of the No. 3 spring. At this time, the liquid in the liquid storage tank 52 flows out through the oil outlet 55 under the action of pressure and flows onto the oil brush cotton ring 53. Then, the left and right movement of the oil brush ring 51 can apply the liquid in the liquid storage tank 52 to the outside of the heat conductive sleeve 13. After the application is completed, the user pushes the oil brush ring 51 to the far right. During this process, the pressure plate abuts against the top cover 31, and causes the pressure ring 54 to move to the left relative to the oil brush ring 51. At this time, the negative pressure generated in the liquid storage tank 52 will cause air to enter the liquid storage tank 52 through the oil outlet hole 55 to empty the liquid in the oil outlet hole 55 to avoid leakage.

[0035] In addition, in order to increase the structural strength of the heat-conducting sleeve 13 , a reinforcing plate is integrally formed on the inner curved surface of the heat-conducting sleeve 13 , and the reinforcing plate is attached to the fixed arc plate 21 .

[0036] In order to increase the density of the comb teeth 15 , two or more comb teeth 15 are accommodated in one through hole.

[0037] It should be additionally explained that, due to the limitations of the cylindrical structure, when the sliding arc plates 22 approach each other, the comb teeth 15 located on the side will first enter the through holes in the heat-conductive sleeve 13, and the user should avoid the ends of the comb teeth 15 completely entering the heat-conductive sleeve 13 when using it, so as to avoid the comb teeth 15 being unable to enter the through holes when the sliding arc plates 22 move outward. This situation does not hinder the use of the hair curling iron with adjustable comb teeth.

[0038] In addition, the wall thickness of the heat-conducting sleeve 13 in the figure is not the actual wall thickness of the final product, and the lengths of the comb teeth 15 at different extension angles are also different. Specifically, the comb teeth 15 extending in the up and down directions are the longest, and the lengths of the comb teeth 15 inclined forward and backward gradually become shorter.

[0039] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
