Description

Technical Field

[0001] This application relates to the field of hair straightening equipment technology, and more specifically, to a clamping component and a hair straightener. Background Technology

[0002] Most hair straighteners and hairdryers currently available are either manually clamped or automatically clamped (pneumatic). Manual clamping is cumbersome and the results vary depending on individual clamping force. Pneumatic clamping, on the other hand, has insufficient clamping force and automatically closes as soon as air is blown, making it impossible to control independently.

[0003] These issues result in hair straightening products not being able to accurately control the temperature of the hair in contact with it and not being able to respond quickly enough, which makes it easy for users to burn their hair and cause damage. In addition, if the temperature control is not accurate, the straightening effect will also be less than satisfactory. Utility Model Content

[0004] In view of the above, this application provides a clamping component for a hair straightener and the hair straightener thereof, which adopts the following technical solution:

[0005] In a first aspect, this application provides a clamping assembly for a hair straightener, including two clamping arms arranged opposite to each other and a connecting structure. The first ends of the two clamping arms are respectively connected to the handle of the hair straightener through the connecting structure. The assembly also includes: a push button, a lever actuator, at least two sliding rods, and at least two rotating shafts; the lever actuator includes: at least two levers.

[0006] The push button is located on the connecting structure and / or the handle, and can be pushed back and forth along a preset push direction;

[0007] The first side of each clamping arm is hinged to the first surface of the corresponding connecting structure via the pivot.

[0008] The two levers are distributed at an angle on both sides of the preset toggle direction, and the first ends of the two levers are respectively hinged to the toggle button;

[0009] The first end of each sliding rod is hinged to the second end of the pull rod, and the second end of each sliding rod is fixedly connected to the second side of the corresponding clamping arm;

[0010] When the lever is pulled back and forth along the preset pulling direction, the two levers are driven to change the included angle movement synchronously. Then, the sliding rod drives the second side of the two clamping arms to slide synchronously in the opposite direction along the preset sliding trajectory around the rotating shaft, so as to achieve clamping or separation between the second sides of the two clamping arms.

[0011] Furthermore, a heating device is provided near the second side of the clamping arm; and / or,

[0012] By placing a heating device near the second side of the clamping arm, the heating temperature can be transferred to the second side of the clamping arm more accurately, which helps to further maintain a stable and precise heating effect on the hair.

[0013] On the second side of the clamping arm, the clamping surfaces of the two clamping arms respectively form mutually cooperating clamping parts.

[0014] By incorporating a clamping section, the clamping arms can better grip the hair.

[0015] Furthermore, the first side and the second side of the clamping arm are arranged opposite each other along the direction of the central axis; wherein, the central axis is the central axis between the two clamping arms arranged opposite each other.

[0016] By setting the first side and the second side of the clamping arm opposite each other along the central axis, the two clamping arms can be better controlled synchronously.

[0017] Furthermore, the first surface of the connecting structure forms a sliding groove that matches the preset sliding trajectory on the sliding rod. After the second end of the sliding rod passes through the sliding groove, the second end of the sliding rod is then fixedly connected to the second side of the corresponding clamping arm.

[0018] By setting a sliding groove in the connecting structure, the second end of the sliding rod passes through the sliding groove and is then fixedly connected to the second side of the corresponding clamping arm, making the overall structure of the hair straightener more aesthetically pleasing and simple.

[0019] Furthermore, along the preset pulling direction, an elastic element is provided on the first side of the transition portion of the pull button or the push button, so that the pull button can be pulled back and forth along the preset pulling direction; wherein, the elastic element can undergo elastic deformation along the preset pulling direction.

[0020] By incorporating an elastic element, after manually pulling the lever to clamp and straighten the hair, releasing the lever will cause it to automatically reset based on the elastic force of the elastic element, thus releasing the hair.

[0021] Furthermore, along the preset pulling direction, the connecting part of the pull button or the push button is provided with a positioning element on the second side opposite to the elastic element, corresponding to the pull limit position, and the connecting part of the pull button or the push button and the positioning element are respectively provided with mutually cooperating magnetic attraction structures on their opposite surfaces; wherein, the pull limit position is the extreme position of the pull button to be pulled to the second side.

[0022] By setting a magnetically based positioning element at the corresponding pull limit position on the second side opposite to the elastic element of the pull button, after manually pulling the pull button to the position corresponding to the pull limit and throughout the entire process of the clamping arm clamping the hair, there is no need to manually apply force to the pull button. The magnetic force can provide a continuous and stable positioning effect on the pull button at this position. After the hair straightening process is completed, only a reverse push force needs to be applied to the pull button to overcome the magnetic force of the positioning element. The pull button can then move in the opposite direction based on the force of the elastic element, thereby causing the clamping arm to release the hair.

[0023] Furthermore, the toggle button also includes a transition part; the first end of the transition part along the preset toggle direction is fixedly connected to the toggle button; the second end of the transition part is respectively hinged to the first end of the two pull rods, so that the first end of the two pull rods is respectively hinged to the toggle button.

[0024] By adding an adapter to the toggle button, the toggle button can be rationally arranged in any desired position, based on the layout of other buttons such as heating buttons on the handle itself.

[0025] Furthermore, the rotating shaft is located at the first end of the clamping arm near the clamping surface; the sliding rod is located at the second end of the clamping arm near the clamping surface; the second end of the clamping surface is opposite to the first end of the clamping surface.

[0026] By setting the rotating shaft at the first end of the clamping arm near the clamping surface and the sliding rod at the second end of the clamping arm near the clamping surface, the rotating shaft and the corresponding sliding rod are kept at the maximum distance within a limited space to increase the torque between them, thereby more effectively clamping and controlling the two clamping arms.

[0027] Furthermore, on the first side of the clamping arm, the clamping surfaces of the two clamping arms are spaced apart by a predetermined distance to facilitate the clamping movement on the second side of the two clamping arms.

[0028] By spacing the two clamping surfaces on the first side of the clamping arm by a preset distance, a certain amount of rotation space is provided for the second side of the two clamping arms to clamp and rotate towards the center, which helps the second side of the two clamping arms to better achieve clamping movement and increase clamping stability.

[0029] Furthermore, the first surface of the connecting structure is circular; the two clamping arms are symmetrically distributed about the diameter of the circle as an axis of symmetry.

[0030] By symmetrically distributing the two clamping arms around the diameter of a circle, it is convenient to uniformly control the clamping and releasing of the two clamping arms in the future.

[0031] Furthermore, the first ends of the two clamping arms extend to form extensions corresponding to the first side of the clamping arms. The extensions are hinged to the first surface of the connecting structure via the pivot, so that the first side of the first end of the clamping arm is hinged to the first surface of the corresponding connecting structure via the pivot.

[0032] By providing an extension, users can easily install or replace the shaft from the outside of the clamping arm, facilitating assembly and subsequent maintenance.

[0033] Furthermore, the first ends of the two pull rods are respectively hinged to the toggle button via a first shaft, and a bearing is provided between the first shaft and the first end of the pull rod; and / or, the first end of each sliding rod is hinged to the second end of the pull rod via a second shaft, and a bearing is provided between the second shaft and the second end of the pull rod.

[0034] By incorporating bearings, the pull rod can be made to move more smoothly.

[0035] Furthermore, the preset pulling direction is parallel to the direction in which the clamping arm connects to the connecting structure; and / or,

[0036] Since the clamping arm is connected to the handle through the connecting structure, the connection direction of the clamping arm, the connecting structure and the handle corresponds to the length direction of the entire hair straightener. By setting the preset pulling direction parallel to the direction of the connection between the clamping arm and the connecting structure, the pulling button can be pulled along the length direction of the entire hair straightener. The pulling button can be set on the connecting structure or the handle, thereby increasing the movement space of the pulling button and making the overall structure more concise.

[0037] The first end and the second end of the sliding rod are fixedly connected in a perpendicular manner to each other.

[0038] Based on the above arrangement, while the pull rod 14 drives the first end of the sliding rod to rotate, the second end of the sliding rod 15 can drive the clamping arm fixedly connected to it to slide around the axis of rotation.

[0039] Secondly, this application provides a hair straightener, including a handle and a clamping assembly of the hair straightener described in any of the above claims.

[0040] By repeatedly pressing the button in the preset direction, the two levers move at the same angle, which in turn causes the second side of the two clamping arms to slide in opposite directions along a preset sliding trajectory around the pivot. This allows the second side of the two clamping arms to clamp or separate, maintaining a stable force each time the hair is clamped. Activating the heating function of the two clamping arms in this clamped state helps the hair straightener maintain a stable and precise heating effect on the hair.

[0041] Furthermore, the handle housing of the handle forms a limiting channel along the preset pulling direction, and the pulling button can be pulled along the limiting channel; and / or,

[0042] By setting a limit channel, it is convenient to limit the movement of the toggle button during the toggle process.

[0043] The connecting structure is located inside the handle housing to form an isolation space between the outer wall of the connecting structure and the inner wall of the handle housing; at least the lever actuator is located within the isolation space.

[0044] By placing at least the lever actuator within an isolated space, the clamping control structure related to the clamping arm can be isolated from the original control circuits, power supply, etc., inside the handle, facilitating assembly and subsequent maintenance.

[0045] Compared with the prior art, the embodiments of this application have the following main advantages:

[0046] In this embodiment, by repeatedly pulling the lever along a preset direction, the two levers are driven to change their angle synchronously. Then, the sliding rods drive the second sides of the two clamping arms to slide synchronously in opposite directions along a preset sliding trajectory around the pivot, so as to achieve clamping or separating movement between the second sides of the two clamping arms. This can maintain a stable force each time the hair is clamped. Subsequently, the heating function of the two clamping arms can be activated in this clamping state, which can help maintain a stable and precise heating effect on the hair.

[0058] This application provides a clamping assembly 10 for a hair straightener, including two clamping arms 1111 disposed opposite to each other and a connecting structure 12. The first ends of the two clamping arms 11 are respectively connected to the handle 30 of the hair straightener (only part of the handle shell is shown in the figure) through the connecting structure 12.

[0059] Typically, various heating components, such as hot air channels, can be installed inside the two clamping arms 11. This allows the heating device 114 to be activated when the clamping arms 11 hold the hair, thus heating and styling the hair during the pulling process. The handle 30 can house the straightener's control circuitry, power supply, etc.

[0060] The clamping assembly 10 also includes: a pull button 13, a lever actuator, at least two sliding rods 15 and at least two rotating shafts 16; the lever actuator includes: at least two pull rods 14.

[0061] The toggle button 13 is located on the connecting structure 12 and / or the handle 30, and can be toggled back and forth along the preset toggle direction F.

[0062] It should be noted that the preset pulling direction can be set arbitrarily according to actual needs. As long as the pulling can drive the two connecting rods to change their angle and move, and ultimately drive the clamping arms 11 to clamp and separate relative to each other, it falls within the scope of protection of this application.

[0063] The first side 111 of each clamping arm is hinged to the first surface of the corresponding connecting structure 12 via a pivot 16.

[0064] Two levers 14 are distributed at an angle on both sides of the preset sliding direction, and the first ends of the two levers 14 are respectively hinged to the sliding button 13.

[0065] Typically, the two levers 14 can be symmetrically distributed on both sides of the preset pulling direction. In addition, they can also be distributed in other asymmetrical ways as needed.

[0066] In addition, the shapes of the sliding rod 15 and the pull rod 14 can be set arbitrarily as needed. For example, the pull rod 14 can be a long rod-shaped structure, and the sliding rod 15 is composed of two parts that are vertically fixedly connected.

[0067] The first end of each sliding rod 15 is hinged to the second end of the pull rod 14, and the second end of each sliding rod 15 is fixedly connected to the second side 112 of the corresponding clamping arm.

[0068] In this embodiment, when the push button 13 is pushed back and forth along the preset pulling direction, the two pull rods 14 move synchronously to change their included angle. Then, the sliding rod 15 drives the second side 112 of the two clamping arms to slide synchronously in the opposite direction along the preset sliding trajectory around the rotating shaft 16, so as to achieve the clamping or separating movement between the second side 112 of the two clamping arms. This can maintain a stable force each time the hair is clamped. Subsequently, when the heating function of the two clamping arms 11 is turned on in this clamping state, it can help maintain a stable and precise heating effect on the hair.

[0069] Continue as Figure 2 As shown, in an optional embodiment, a heating device 114 is disposed near the second side 112 of the clamping arm.

[0070] Based on the previous embodiment, the two clamping arms are used to clamp hair between their second sides 112. This embodiment of the application provides a heating device 114 near the second side 112 of the clamping arms, which can more accurately transfer the heating temperature to the second side 112 of the clamping arms, thereby helping to maintain a stable and precise heating effect on the hair.

[0071] It should be noted that, in addition to the above, the heating device 114 can also be set at any desired position on the clamping arm 11, all of which fall within the scope of protection of this application.

[0072] Continue as Figure 1 As shown, in an optional embodiment, on the second side 112 of the clamping arm, the clamping surfaces (113) of the two clamping arms 11 respectively form mutually cooperating clamping portions.

[0073] The embodiments of this application provide clamping parts (e.g., mating planes) to help clamp the hair more effectively.

[0074] Continue as Figure 2 As shown, in an optional embodiment, the first side 111 and the second side 112 of the clamping arm are arranged opposite each other along the direction of the central axis O; wherein, the central axis is the central axis between the two clamping arms 11 arranged opposite each other.

[0075] By setting the first side 111 and the second side 112 of the clamping arm opposite each other along the central axis, the two clamping arms 11 can be better controlled synchronously.

[0076] It should be noted that, in addition to the embodiments described above, the first and second sides of the clamping arm can also be set at any desired position, as long as they can achieve the purpose described in this application, such that the clamping arm 11 can rotate around the rotating shaft 16 under the drive, and all of them fall within the scope of protection of this application.

[0077] Continue as Figure 5 As shown, in an optional embodiment, the first surface 121 of the connecting structure 12 forms a sliding groove 122 that matches the preset sliding trajectory of the sliding rod 15. After the second end of the sliding rod 15 passes through the sliding groove 122, the second end of the sliding rod 15 is then fixedly connected to the second side 112 of the corresponding clamping arm.

[0078] In this embodiment of the application, by setting a sliding groove 122 in the connecting structure 12, and after the second end of the sliding rod 15 passes through the sliding groove, the second end of the sliding rod 15 is fixedly connected to the second side 112 of the corresponding clamping arm, which makes the overall structure of the hair straightener more beautiful and simple.

[0079] Continue as Figure 4 and 5 As shown, in an optional embodiment, an elastic element 19 (e.g., a spring) is provided on the first side of the adapter 131 of the push button 13 or pull button (detailed description of the adapter is provided in later embodiments) along a preset push direction F, so that the push button 13 can be pushed back and forth along the preset push direction; wherein, the elastic element 19 can undergo elastic deformation along the preset push direction. For example, the adapter 131 of the push button 13 or pull button can be connected to the connecting structure 12 or the handle 30 through the elastic element 19.

[0080] In this embodiment of the application, by setting an elastic element 19, after manually pulling the pull button 13 (at which time the elastic element generates an elastic force due to deformation) to drive the clamping arm 11 to clamp and straighten the hair, the pull button 13 can be automatically reset based on the elastic force of the elastic element 19 to release the hair.

[0081] Continue as Figure 4 and 5 As shown, in an optional embodiment, along the preset pulling direction F, the transition part 131 of the pull button 13 or the push button is provided with a positioning member 20 on the second side opposite to the elastic member 19, and the transition part 131 of the pull button 13 or the push button and the positioning member 20 are respectively provided with mutually cooperating magnetic structures on their opposite surfaces; wherein, the pull limit is the extreme position of the pull button 13 being pulled to the second side.

[0082] In this embodiment, a magnetically based positioning element 20 is provided on the second side of the pull button (or the adapter 131 of the pull button) corresponding to the pull limit position opposite to the elastic element 19. After the pull button 13 is manually pulled to the position corresponding to the pull limit position and during the entire process of the clamping arm 11 clamping the hair, there is no need to manually apply force to the pull button 13. The magnetic force can provide a continuous and stable positioning effect on the pull button 13 at this position. After the straightening process is completed, only a reverse push force is needed to the pull button 13 to overcome the magnetic force of the positioning element. The pull button 13 can then move in the opposite direction based on the force of the elastic element 19, thereby causing the clamping arm 11 to release the hair.

[0083] Continue as Figure 4 and 5 As shown, in an optional embodiment, the toggle button 13 further includes an adapter 131; the first end of the adapter 131 along a preset toggle direction is fixedly connected to the toggle button 13; the second end of the adapter 131 is hinged to the first ends of the two pull rods 14 respectively.

[0084] It should be noted that when the toggle button 13 also includes a transition part 131, based on the previous embodiments, the elastic element and the positioning element described in this application embodiment are respectively disposed on the first side and the second side of the toggle button 13, which can also be regarded as the elastic element and the positioning element being respectively disposed on the first side and the second side of the transition part 131.

[0085] Specifically, the shape and size of the adapter can be arbitrarily set according to actual needs.

[0086] This application embodiment adds a connecting part to the toggle button. Based on the connection of the connecting part, the toggle button can be reasonably arranged in any desired position in combination with the layout of other heating buttons on the handle itself.

[0087] Continue as Figure 1 and 2 As shown, in an optional embodiment, the pivot 16 is located at the first end of the clamping arm 11 near the clamping surface (113); the sliding rod 15 is located at the second end of the clamping arm 11 near the clamping surface (113); wherein the first end and the second end of the clamping surface (113) are opposite each other.

[0088] In this embodiment, the rotating shaft is positioned at the first end of the clamping arm near the clamping surface, and the sliding rod is positioned at the second end of the clamping arm near the clamping surface. This allows the rotating shaft and the corresponding sliding rod to maintain the maximum distance within a limited space, thereby increasing the torque between them and more effectively clamping and controlling the two clamping arms.

[0089] It should be noted that, in addition to the embodiments described above, the rotating shaft and sliding rod can be set at any desired position as needed. As long as the sliding rod can drive the clamping arm to rotate around the rotating shaft, thereby completing the clamping and releasing of the hair, it falls within the scope of protection of this application.

[0090] Continue as Figure 1 As shown, in an optional embodiment, on the first side 111 of the clamping arm, the clamping surfaces (113) of the two clamping arms 11 are spaced apart by a preset distance.

[0091] By spacing the two clamping surfaces on the first side of the clamping arm by a preset distance, a certain amount of rotation space is provided for the second side of the two clamping arms to clamp and rotate towards the center, which helps the second side of the two clamping arms to better achieve clamping movement and increase clamping stability.

[0092] Continue as Figure 4 and 5 As shown, in an optional embodiment, the first surface 121 of the connecting structure 12 is circular; the two clamping arms 11 are symmetrically distributed about the diameter of the circle as the axis of symmetry.

[0093] By symmetrically distributing the two clamping arms around the diameter of a circle, it is convenient to uniformly control the clamping and releasing of the two clamping arms. In addition to the above, the clamping arms 11 can also be asymmetrically distributed as needed; any distribution that achieves the purpose of the invention falls within the scope of protection of this application.

[0094] Continue as Figure 2 As shown, in an optional embodiment, the first ends of the two clamping arms 11 extend to form extensions 18 corresponding to the first side 111 of the clamping arms. The extensions 18 are hinged to the first surface of the connecting structure 12 via a pivot 16, so that the first side 111 of the clamping arm is hinged to the first surface 121 of the corresponding connecting structure 12 via the pivot 16.

[0095] By setting an extension, for example: Figure 2 As shown, the extension 18 can be a plate-like structure, which makes it convenient for users to install or replace the rotating shaft from the outside of the clamping arm, facilitating assembly and subsequent maintenance.

[0096] Continue as Figure 4 and 5 As shown, in an optional embodiment, the first ends of the two pull rods 14 are respectively hinged to the toggle button 13 via a first shaft, and a bearing 21 is provided between the first shaft and the first ends of the pull rods 14; and / or,

[0097] The first end of each sliding rod 15 is hinged to the second end of the pull rod 14 via a second shaft, and a bearing 21 is provided between the second shaft and the second end of the pull rod 14.

[0098] The embodiment of this application makes the pull rod 14 move more smoothly by setting the bearing 21.

[0099] Continue as Figure 4 and 5 As shown, in an optional embodiment, the preset pulling direction F is parallel to the direction in which the clamping arm 11 is connected to the connecting structure 12.

[0100] In this embodiment, since the clamping arm is connected to the handle through the connecting structure, the connection direction of the clamping arm, the connecting structure and the handle corresponds to the length direction of the entire hair straightener. By setting a preset pulling direction parallel to the direction of the connection between the clamping arm and the connecting structure, the pulling button can be pulled along the length direction of the entire hair straightener. The pulling button can be set on the connecting structure or the handle, thereby increasing the movement space of the pulling button and making the overall structure simpler.

[0101] Continue as Figure 5 As shown, in an optional embodiment, the first end and the second end of the sliding rod 15 are fixedly connected in a mutually perpendicular manner.

[0102] Based on the above arrangement, in this application, while the pull rod 14 drives the first end of the sliding rod to rotate, the second end of the sliding rod 15 can drive the clamping arm fixedly connected to it to slide around the axis of rotation.

[0103] Based on the clamping assembly 10 of the hair straightener described in the previous embodiment, this application embodiment also provides a hair straightener, which includes the clamping assembly 10 and handle 30 of the hair straightener described in the above embodiment (only the structure of the handle part is shown in the figure).

[0104] In this embodiment, by repeatedly pressing the button along a preset direction, the two levers move at a synchronized angle. This, in turn, causes the second sides of the two clamping arms to slide synchronously in the opposite direction along a preset sliding trajectory around the axis of rotation via the sliding rod. This allows the second sides of the two clamping arms to clamp or separate, maintaining a stable force each time the hair is clamped. Subsequently, activating the heating function of the two clamping arms in this clamped state helps the hair straightener maintain a stable and precise heating effect on the hair.

[0105] Continue as Figure 1 As shown, in an optional embodiment, the handle housing 32 of the handle 30 (only part of the handle housing is shown in the figure) forms a limiting channel 31 along the preset pulling direction F, and the pull button 13 can be pulled along the limiting channel 31.

[0106] By setting a limit channel, it is convenient to limit the movement of the toggle button during the toggle process.

[0107] Continue as Figure 4 As shown, in an optional embodiment, the connecting structure 12 is located inside the handle housing 32 to form an isolation space between the outer wall of the connecting structure 12 and the inner wall of the handle housing 32; at least the lever actuator is located within the isolation space.

[0108] By placing at least the lever actuator within an isolated space, the clamping control structure related to the clamping arm can be isolated from the original control circuits, power supply, etc., inside the handle, facilitating assembly and subsequent maintenance.

[0109] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.

This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
