[0045] This utility model proposes a hair styling tool.

[0046] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the hair styling tool includes a housing, a drive unit 40, two heating plate assemblies 20 and two lifting mechanisms 50. The housing includes a handle 11 and two clamping arms 12. The two clamping arms 12 are both located at the front end of the handle 11 and are arranged opposite to each other. Each clamping arm 12 has an arc-shaped plate 30 on its outer side. Each heating plate assembly 20 is correspondingly located on the inner side of one clamping arm 12.

[0047] Two lifting mechanisms 50 are respectively located on two clamping arms 12, and the lifting mechanism 50 on each clamping arm 12 is connected to the corresponding arc plate 30; the driving component 40 is installed on the handle 11 and is connected to the lifting mechanism 50 on the two clamping arms 12 for transmission, so as to drive the arc plate 30 to move along the thickness direction of the clamping arm 12.

[0048] Specifically, the thickness direction of the clamp arm 12 is perpendicular to the length and width directions of the clamp arm 12. The arc plate 30 has a curling surface facing away from the clamp arm 12. The curling surface is a convex arc surface that extends along the length direction of the clamp arm 12 and bends along the width direction of the clamp arm 12. The heating plate assemblies 20 on the two clamp arms 12 are arranged opposite to each other. In use, the hair can be heated and straightened by the two heating plate assemblies 20. When curling is required, after heating a part of the hair by the two heating plate assemblies 20, the hair styling tool is moved to heat the adjacent part of the heated hair. At the same time, the heated hair is wrapped around the clamp arm 12 and the arc plate 30. After the hair wrapped around the arc plate 30 cools down, the hair can be styled into a curl.

[0049] Because the curved plate 30 can move along the thickness direction of the clamping arm 12 under the drive of the drive component 40, the distance between the curved plate 30 and the outer side of the clamping arm 12 can be adjusted, which is equivalent to adjusting the diameter of the curling iron. Before use, the state of the curved plate 30 can be adjusted as needed to curl hair and obtain different curling effects. Since the curved plate 30 is located on the outside of the clamping arm 12, the curved plate 30 and the heating plate assembly 20 do not affect each other.

[0050] This utility model provides an arc-shaped plate 30 and a lifting mechanism 50 connecting the arc-shaped plate 30 on the outer side of each clamping arm 12, and a driving member 40 on the handle 11. The driving member 40 is connected to the lifting mechanism 50 on the two clamping arms 12. The driving member 40 drives the arc-shaped plate 30 to move along the thickness direction of the clamping arm 12, so that the height of the arc-shaped plate 30 relative to the outer side of the clamping arm 12 is adjustable, thereby realizing the adjustable curling diameter and achieving a variety of curling effects.

[0051] In some embodiments, the drive member 40 is annular and rotatably sleeved on the handle 11. Specifically, the rotation axis of the drive member 40 is approximately parallel to the central axis of the handle 11, allowing the user to manually rotate the drive member 40 to raise and lower the arc-shaped plate 30 on the clamping arm 12. This structure is simple and easy to operate. Of course, in other embodiments, the drive member 40 may also be a motor disposed within the handle 11; or the drive member 40 may be slidably mounted on the handle 11 along its length and have an operating portion exposed outside the handle 11.

[0052] In some embodiments, a positioning groove 111 is provided on the outside of the handle 11. The positioning groove 111 is annular and extends circumferentially along the handle 11. The drive member 40 is installed in the positioning groove 111. Specifically, the drive member 40 protrudes out of the positioning groove 111. By setting the drive member 40 in the positioning groove 111, the protrusion height of the drive member 40 relative to the outer surface of the handle 11 can be reduced. At the same time, it is convenient for the drive member 40 to be positioned and installed and limited after installation, thereby improving the reliability of the drive member 40.

[0053] In some embodiments, the curved plate 30 has a first state of being in contact with the clamping arm 12 and a second state of being away from the clamping arm 12. One of the handle 11 and the drive member 40 is provided with a first latching protrusion 114, and the other with a first latching groove 41. In the second state, the first latching protrusion 114 engages with the first latching groove 41. That is, in the second state, the rotation of the drive member 40 can be restricted by the first latching protrusion 114 engaging with the first latching groove 41, thereby keeping the curved plate 30 in the second state and reducing the possibility of the curved plate 30 automatically switching from the second state to the first state during use, making it convenient for the user. Furthermore, this structure is simple and helps to simplify the structure of hair styling tools. When it is necessary to switch the curved plate 30 from the second state to the first state, it is only necessary to forcefully rotate the drive member 40, causing the drive member 40 to elastically deform and allowing the first latching protrusion 114 to slide out of the first latching groove 41. Optionally, there are multiple first protrusions 114, which are distributed at intervals along the circumference of the handle 11. The number of first slots 41 is not less than the number of first protrusions 114. In the second state, each first protrusion 114 is engaged in a first slot 41.

[0054] The lifting mechanism 50 has various structures; for example, in some embodiments, such as... Figures 1 to 7 As shown, the handle 11 is provided with a first through hole 115, and the drive member 40 is provided covering the first through hole 115. The drive member 40 is provided with a plurality of first transmission teeth 42 on its inner side, and the plurality of first transmission teeth 42 are distributed sequentially along the inner wall circumferentially of the drive member 40. The lifting mechanism 50 includes a transmission member 51, a transmission shaft 52, a first gear 53 and a second gear 54. The transmission member 51 is fixed on the arc plate 30 and is provided with a rack portion 511 extending along the thickness direction of the clamping arm 12. The transmission shaft 52 is rotatably mounted on the clamping arm 12 and extends to the inner side of the drive member 40. The first gear 53 and the second gear 54 are both provided on the transmission shaft 52. The first gear 53 meshes with the rack portion 511, and the second gear 54 is located at the first through hole 115 and meshes with the first transmission teeth 42. When the drive member 40 is rotated, it drives the transmission shaft 52 to rotate through the cooperation of the first transmission gear 42 and the second gear 54. The transmission shaft 52 drives the arc plate 30 to rise and fall through the cooperation of the first gear 53 and the rack portion 511. It should be noted that the first gear 53 can be a complete gear or an incomplete gear (i.e., at least one tooth). The transmission teeth on the rack portion 511 and the transmission teeth on the first gear 53 can be standard teeth or non-standard teeth, as long as the first gear 53 can drive the transmission member 51 to move along the thickness direction of the clamping arm 12.

[0055] Furthermore, the transmission component 51 has a mounting groove 512 on the side facing away from the arc-shaped plate 30, the rack portion 511 is located on the side wall of the mounting groove 512, and the first gear 53 is located within the mounting groove 512. Specifically, the dimension of the transmission component 51 along the width direction of the clamping arm 12 is larger than the diameter of the first gear 53, the rack portion 511 is located on one side wall of the mounting groove 512, and the other side wall of the mounting groove 512 is spaced apart from the first gear 53. This arrangement allows for a larger contact area between the transmission component 51 and the arc-shaped plate 30, improving the installation stability of the transmission component 51, while ensuring that the first gear 53 is centrally positioned to guarantee force balance.

[0056] Furthermore, there are multiple transmission components 51, which are spaced apart along the length of the clamping arm 12. Multiple first gears 53 are mounted on the transmission shaft 52, and each of the first gears 53 meshes with the transmission parts of the multiple transmission components 51. This improves the uniformity of force distribution at various positions along the length of the arc-shaped plate 30 and enhances the smoothness of its lifting and lowering.

[0057] Furthermore, the two clamping arms 12 are defined as the first clamping arm and the second clamping arm, respectively. The first clamping arm is rotatably mounted on the front end of the handle 11, and the second clamping arm is fixed to the front end of the handle 11. The hair styling tool has an open state where the first clamping arm is away from the second clamping arm and a closed state where the first clamping arm is close to the second clamping arm. In the closed state, the second gear 54 meshes with the first transmission gear 42. The handle 11 has clearance space within it for the corresponding transmission shaft 52 and the second gear 54 to move when the first clamping arm moves from the closed state to the open state. That is, in both the open and closed states, the second gear 54 on the second clamping arm meshes with the corresponding first transmission gear 42 on the drive member 40. In the closed state, the second gear 54 on the first clamping arm meshes with the corresponding first transmission gear 42 on the drive member 40. When the first clamping arm is opened, the drive shaft 52 and the second gear 54 on the first clamping arm move away from the first drive gear 42 to the clearance space. When the first clamping arm is in the open state, the second gear 54 on the first clamping arm is spaced apart from the corresponding first drive gear 42 on the drive component 40. This avoids the restriction of the lifting mechanism 50 when opening the first clamping arm, and at the same time allows the first clamping arm to open to a larger extent, making it convenient for the user.

[0058] Of course, in other embodiments, both clamping arms 12 can be fixed to the front end of the handle 11, and the heating plate assembly 20 can be movably mounted on the clamping arm 12 along the thickness direction of the clamping arm 12, so that the heating plate assembly 20 on the two clamping arms 12 can be opened and closed.

[0059] Optionally, one of the two lifting mechanisms 50 has a limiting part 521 on the drive shaft 52 corresponding to the first clamping arm. The outer peripheral surface of the limiting part 521 has a second slot 522, and the clamping arm 12 has a limiting member 121. The arc-shaped plate 30 has a first state of being in contact with the first clamping arm and a second state of being away from the first clamping arm. In the second state, the limiting member 121 is engaged in the second slot 522. That is, in the closed state, the arc-shaped plate 30 can be driven to the second state by the driving member 40, so that the limiting member 121 is engaged in the second slot 522. In this way, when the first clamping arm is opened, the arc-shaped plate 30 can still be kept in the second state for user convenience.

[0060] In other embodiments, such as Figures 8 to 12 As shown, the lifting mechanism 50 includes a first slider 55, a second slider 56, and a connecting shaft 57. The first slider 55 is slidably mounted on the clamping arm 12, and the second slider 56 is fixed to the arc plate 30. A wedge-shaped engagement structure extending along the length direction of the clamping arm 12 is provided between the first slider 55 and the second slider 56. The connecting shaft 57 is connected between the first slider 55 and the driving member 40. The driving member 40 is used to drive the connecting shaft 57 to move along the length direction of the clamping arm 12, and to drive the arc plate 30 to rise and fall through the wedge-shaped engagement structure between the first slider 55 and the second slider 56.

[0061] Specifically, the arc-shaped plate 30 has a first state of being in contact with the first clamping arm and a second state of being away from the first clamping arm. The wedge-shaped mating structure includes a first sliding portion 551 located on the first slider 55 and a second sliding portion 561 located on the second slider 56. At least one of the first sliding portion 551 and the second sliding portion 561 extends along the length direction of the clamping arm 12, and the first sliding portion 551 and the second sliding portion 561 slide against each other.

[0062] In this embodiment, the first sliding portion 551 gradually extends at an angle away from the handle 11 and away from the heating plate assembly 20. When the arc plate 30 is in the first state, the second sliding portion 561 at least partially abuts against the end of the first sliding portion 551 near the handle 11. When the driving member 40 drives the connecting shaft 57 and the first slider 55 to move in the direction of the handle 11, the first sliding portion 551 can gradually lift the second sliding portion 561, thereby causing the arc plate 30 to gradually move towards the second state. Conversely, when the arc plate 30 is in the second state, the second sliding portion 561 at least partially abuts against the end of the first sliding portion 551 away from the handle 11. When the driving member 40 drives the connecting shaft 57 and the first slider 55 to move in the direction away from the handle 11, the second sliding portion 561 gradually slides down, thereby causing the arc plate 30 to gradually move towards the first state. This makes the raising and lowering of the arc plate 30 more stable.

[0063] Optionally, the first sliding part 551 extends gradually at an angle away from the handle 11 and away from the heating plate assembly 20, and the second sliding part 561 also extends gradually at an angle away from the handle 11 and away from the heating plate assembly 20.

[0064] Optionally, the handle 11 has a first through hole 115, and the driving member 40 is annular and covers the first through hole 115. The driving member 40 is rotatably sleeved on the handle 11. The driving member 40 has a spirally extending guide groove 43 inside. The lifting mechanism 50 also includes a sliding member 58, which is fixed to the connecting shaft 57 and slidably installed at the first through hole 115. The sliding member 58 has a guide protrusion 582, which is slidably installed in the guide groove 43. Specifically, the guide groove 43 is provided on the inner wall of the driving member 40 and gradually extends along the circumference of the driving member 40 in the direction from one end to the other. When the arc plate 30 is in the first state, the guide protrusion 582 is located at the end of the guide groove 43 near the clamping arm 12. Thus, when the driving member 40 is rotated, the driving member 40 can move along the length direction of the clamping arm 12 with the cooperation of the guide groove 43 and the guide protrusion 582.

[0065] Furthermore, the clamping arm 12 is provided with a mounting hole 122, which is a long strip extending along the length of the clamping arm 12. The first slider 55 and the second slider 56 are both installed in the mounting hole 122. That is, the first slider 55 and the second slider 56 can be restricted to move along the width of the clamping arm 12 through the mounting hole 122, which can improve the stability of the first slider 55 and the second slider 56 and simplify the structure of the clamping arm 12.

[0066] Furthermore, the first slider 55 is provided with a limiting groove 552 on one side of the first sliding part 551. The limiting groove 552 is parallel to the first sliding part 551. The second slider 56 is provided with a limiting protrusion 562. The limiting protrusion 562 is slidably installed in the limiting groove 552 to restrict the second sliding part 561 from disengaging from the first sliding part 551. That is, the limiting groove 552 is provided on the structure on one side of the first sliding part 551, and the opening of the limiting groove 552 faces the side where the first sliding part 551 is located. In this way, the second slider 56 and the first slider 55 can be restricted from separating in the thickness direction of the clamping arm 12, and the arc plate 30 is prevented from falling off the clamping arm 12.

[0067] Furthermore, multiple wedge-shaped mating structures are provided between the first slider 55 and the second slider 56, and these multiple wedge-shaped mating structures are distributed at intervals along the length direction of the clamping arm 12; this can improve the uniformity of force at various positions along the length direction of the arc plate 30 and improve the smoothness of the lifting and lowering of the arc plate 30.

[0068] Furthermore, the two clamping arms 12 are defined as the first clamping arm and the second clamping arm, respectively. The first clamping arm is rotatably mounted on the front end of the handle 11, and the second clamping arm is fixed on the front end of the handle 11. The sliding component 58 of the two lifting mechanisms 50 corresponding to the first clamping arm includes a third slider 581 and a limiting block 584. The third slider 581 is slidably mounted on the first through hole 115 along the length direction of the handle 11 and is provided with a guide protrusion 582. The side of the third slider 581 opposite to the guide protrusion 582 is provided with a locking hole 583. The limiting block 584 is fixed on the connecting shaft 57 and has a limiting locking protrusion 585.

[0069] The hair styling tool has an open state where the first clamping arm is away from the second clamping arm and a closed state where the first clamping arm is close to the second clamping arm. In the closed state, the limiting protrusion 585 fits into the locking hole 583, and the handle 11 has clearance space for the limiting block 584 to move when the first clamping arm moves from the closed state to the open state. That is, in both the open and closed states, the lifting mechanism 50 on the second clamping arm always cooperates with the driving member 40. In the closed state, the limiting protrusion 585 on the first clamping arm engages in the locking hole 583. At this time, when the driving member 40 rotates, it can drive the transmission shaft 52 to move through the sliding part 58 on the first clamping arm. When the first clamping arm is opened, the limiting block 584 on the first clamping arm moves away from the locking hole 583 along with the first clamping arm. This avoids the restriction of the lifting mechanism 50 when opening the first clamping arm, and at the same time allows the first clamping arm to open to a larger extent, making it convenient for the user.

[0070] In some embodiments, the outer side of the clamping arm 12 is provided with a receiving groove 123, and the arc-shaped plate 30 is disposed in the receiving groove 123; this can reduce the protrusion height of the arc-shaped plate 30 relative to the outer side of the clamping arm 12, and reduce the possibility of the arc-shaped plate 30 being hooked when stored.

[0071] In some embodiments, the handle 11 is provided with a first air duct 112 and an air inlet 113 communicating with the first air duct 112, and the clamp arm 12 is provided with a second air duct 124 and a ventilation hole 125 communicating with the second air duct 124. The second air duct 124 communicates with the first air duct 112, and the ventilation hole 125 is located in the area covered by the arc plate 30. The arc plate 30 is provided with an air outlet 31 corresponding to the position of the ventilation hole 125. The hair styling tool also includes a blower fan 60, which is disposed inside the first air duct 112. That is, in use, the blower fan 60 can drive airflow from the air inlet 113 into the first air duct 112 and the second air duct 124, and finally blow it out through the ventilation hole 125 and the air outlet 31. In this way, when the hair is wrapped around the arc plate 30, the airflow blown out from the air outlet 31 can remove the heat from the hair, allowing the hair to cool and set quickly, which can improve the curling effect.

[0072] Optionally, air inlets 113 are provided on both opposite sides of the handle 11 and on the rear end face of the handle 11. This increases the air intake area, which helps to increase the air volume and improve the cooling speed of the hair.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
