[0018] As attached Figure 1-2 As shown in the figure, this embodiment demonstrates a floating hair straightener, including two hinged handle assemblies and two heating plate assemblies 4 respectively movably disposed on opposite sides of the two handle assemblies; the heating plate assembly 4 extends at least partially out of the handle assembly, and the handle assembly is also provided with an elastic floating component, the end of the floating component away from the handle assembly abutting against the heating plate assembly 4, causing the heating plate assembly 4 to have a first floating state of approaching or moving away from the corresponding handle assembly, and a second floating state of offset and tilting relative to the corresponding handle assembly, so that the floating hair straightener can automatically adjust the pressure in the working state.

[0019] The unit comprises two handle assemblies: an upper handle assembly 2 and a lower handle assembly 3. The upper handle assembly 2 and the lower handle assembly 3 are hinged together by a locking ring 1. The locking ring 1 connects the upper handle assembly 2 and the lower handle assembly 3, allowing them to open and close hingedly around the locking ring 1.

[0020] Heating plate assemblies 4 are installed on the inner sides of both the upper handle assembly 2 and the lower handle assembly 3. The heating plate assembly 4 includes a heat conduction panel 5, a heating element 6, and a heat insulation sleeve 7. The heating element 6 is disposed inside the heat insulation sleeve 7, and the heat conduction panel 5 is disposed on the heat insulation sleeve 7. Further, the heat conduction panel 5 can be made of ceramic, aluminum alloy, or titanium; this embodiment is not limited to this. The internal heating element 6 can be a PTC heating element, a heating wire, or a combination of PTC and NTC; this embodiment is not limited to this. After being powered on, the heating plate assembly 4 heats up to the set temperature for direct heating. The heat insulation sleeve 7 effectively blocks the heat from the heating element 6 from being transferred to the handle, preventing burns.

[0021] The floating assembly includes at least two elastic members, one end of each elastic member being connected to the handle assembly and the other end being connected to a floating member. Furthermore, the heating plate assembly 4, facing the handle assembly, has a number of positioning grooves 21 for abutting the floating member, and these positioning grooves 21 are configured as a trumpet-shaped unfolding structure. The end of the floating member abutting the positioning groove 21 is configured as an arc-shaped conical surface structure matching the shape of the positioning groove 21, allowing the heating plate assembly 4 to have a first floating state and a second floating state that move relative to the handle assembly.

[0022] Specific examples Figure 3-6 As shown, this embodiment has two elastic members and two floating members, namely a first floating member 19, a second floating member 20, a first elastic member 16, and a second elastic member 17. One end of the first elastic member 16 abuts against the handle assembly, and the other end abuts against the first floating member 19; one end of the second elastic member 17 abuts against the handle assembly, and the other end abuts against the second floating member 20; both the first floating member 19 and the second floating member 20 are lower than the heating plate assembly 4.

[0023] The handle assembly also includes a connection module that connects the heating plate assembly 4 and the handle assembly. The first floating member 19 and the second floating member 20 are connected to the connection module. The floating assembly also includes a third elastic member 18, one end of which abuts against the handle assembly and the other end against the connection module.

[0024] When the hair is clamped, the thickness of the hair will cause the heating plate assembly 4 to be subjected to reverse pressure, which will push the first floating member 19 and the second floating member 20 to compress the first elastic member 16 and the second elastic member 17. At the same time, the third elastic member 18 provides overall cushioning, so that the clamping force is moderate and the hair is not pulled.

[0025] Specifically, the connection module includes a connecting sleeve 10, a rotating shaft structure, a connecting port 11, and a rotating hole structure on the edge of the connecting port 11. A third elastic element 18 abuts against the connecting sleeve 10. The rotating shaft structure includes two first rotating blocks 12 and two second rotating blocks 13, which are disposed on the heating plate assembly 4. The first rotating blocks 12 are distributed along the length direction of the heating plate assembly 4, and the second rotating blocks 13 are distributed along the width direction of the heating plate assembly 4. The rotating hole structure includes two first rotating grooves 14 adapted to the first rotating blocks 12, and two second rotating grooves 15 adapted to the second rotating blocks 13, which are used to limit the maximum stroke of the heating plate assembly 4 relative to the handle assembly.

[0026] The first rotating block 12 is symmetrically arranged on both sides of the opening 25 along the Y-axis of the coordinate system, and the second rotating block 13 is symmetrically arranged on both sides of the opening 25 along the X-axis of the coordinate system.

[0027] In this embodiment, the heat insulation sleeve 7 is rotated in the length direction by the cooperation of two first rotating blocks 12 and two first rotating grooves 14; and the heat insulation sleeve 7 is rotated in the width direction by the cooperation of two second rotating blocks 13 and two second rotating grooves 15. At the same time, the heat insulation sleeve 7 can drive the heat conduction panel 5 to rotate, thereby realizing the rotation of the heat conduction panel 5 in the length or width direction of the heat insulation sleeve 7, that is, realizing the rotation of the heat conduction panel 5 in the length direction of the handle assembly.

[0028] Specifically, the length direction of the aforementioned heat insulation sleeve 7 refers to... Figure 4 The length on the X-axis of the coordinate system, and the width direction of the heat insulation sleeve 7 refer to... Figure 4 The length on the Y-axis in the coordinate system.

[0029] Thanks to the combination of the rotating shaft structure and the rotating hole structure, the heating plate assembly 4 can be finely adjusted in the length and width directions to adapt to different hairstyle requirements, such as straight hair, inward curl, outward curl, etc.

[0030] This embodiment, through the connection module, creates a certain amount of space for movement between the heating plate assembly 4 and the upper handle assembly 2, as well as between the heating plate assembly 4 and the lower handle assembly 3. Furthermore, the floating component allows the heating plate assembly 4 to rotate 360 ​​degrees, enabling the angle of the upper and lower plates to be freely adjusted according to individual hair thickness and density. This avoids pulling on the hair caused by large-angle rotation or excessive force, thus improving the user experience and the straightening effect.

[0031] Furthermore, both the upper handle assembly 2 and the lower handle assembly 3 include a handle body 8 and a handle cover 9 that are connected to each other. The handle body 8 and the handle cover 9 can be connected by screws or snap-fit ​​connections, etc., and this embodiment does not impose any limitations on this.

[0032] Specific examples Figure 3-6 As shown, the connecting module connects the heat insulation sleeve 7 and the handle cover 9. The connecting module includes a connecting sleeve 10, a rotating shaft structure, a connecting port 11 on the handle cover 9, and a rotating hole structure on the edge of the connecting port 11.

[0033] The handle cover 9 has a groove 29 for the heating plate assembly 4 to be inserted into, and a connection port 11 is located at the top or bottom of the groove 29. At least one-third of the thickness of the heating plate assembly 4 extends beyond the opening of the groove 29 to ensure sufficient movement space for the heating plate assembly 4. Specifically, as shown... Figure 3 As shown, the groove 29 of the handle cover 9 of the upper handle assembly 2 is recessed upwards. At this time, the connection port 11 is located at the top of the groove 29 on the handle cover 9. The heating plate assembly 4 extending at least 1 / 3 of its width from the opening end of the groove 29 means that the thickness of the heating plate assembly 4 extending downwards from the groove 29 exceeds 1 / 3 of its own thickness.

[0034] like Figure 6 As shown, the groove 29 of the handle cover 9 of the lower handle assembly 3 is recessed downwards. At this time, the connection port 11 is located at the bottom of the groove 29 on the handle cover 9. The heating plate assembly 4 extending at least 1 / 3 of its width from the opening end of the groove 29 means that the thickness of the heating plate assembly 4 extending upwards from the groove 29 exceeds 1 / 3 of its own length. The thickness of the heating plate assembly 4 mentioned above refers to... Figure 3 Or the length on the Z-axis of coordinate system 6.

[0035] like Figure 3 As shown, the bottom of the connecting sleeve 10 is fixedly connected to the heat insulation sleeve 7, and the connecting sleeve 10 and the heat insulation sleeve 7 can be an integrally formed structure. The top of the connecting sleeve 10 is inserted into the connecting port 11 on the handle cover 9.

[0036] Positioning grooves 21 are provided on both sides of the heat insulation sleeve 7, and the positioning grooves 21 cooperate with the first floating member 19 and the second floating member 20 respectively.

[0037] The first elastic element 16 and the second elastic element 17 are disposed within the space formed by the handle body 8 and the handle cover 9, and the first floating member 19 and the second floating member 20 protrude from the handle cover 9. The first floating member 19 and the second floating member 20 protrude from the handle cover 9 and abut against the positioning grooves 21 on both sides of the heat insulation sleeve 7 to ensure floating stability. The cooperation structure between the floating block and the positioning grooves 21 of the heat insulation sleeve 7 can also ensure the symmetry of pressure distribution when clamping the gun.

[0038] In some embodiments, the handle cover 9 is provided with a through hole on the end face near the heat insulation sleeve 7, which allows the first floating member 19 and the second floating member 20 to extend out of the handle cover 9 as a whole. After the first floating member 19 and the second floating member 20 extend out of the end face of the handle cover 9 with the through hole, they abut against the end face of the heat insulation sleeve 7 near the handle cover 9.

[0039] In other embodiments, the handle cover 9 is provided with a through hole on the end face near the heat insulation sleeve 7, through which the first floating member 19 and the second floating member 20 can extend out of the handle cover 9 as a whole. The through hole can only allow the protruding ends of the first floating member 19 and the second floating member 20 to extend out. The protruding ends of the first floating member 19 and the second floating member 20 both extend out of the end face of the handle cover 9 with the through hole and abut against the end face of the heat insulation sleeve 7 near the handle cover 9.

[0040] The first elastic element 16, the second elastic element 17 and the third elastic element 18 mentioned above are springs or elastic rubber columns.

[0041] like Figure 4 and 7 As shown, the heat insulation sleeve 7 has a front sleeve 22 and a middle sleeve 23 at one end. The front sleeve 22 is detachable from the heat insulation sleeve 7, and the middle sleeve 23 is fixedly connected to the front sleeve 22. Specifically, the front sleeve 22 can be connected to the heat insulation sleeve 7 by plugging or snapping, etc., and this embodiment does not limit this. The detachable connection of the front sleeve 22 facilitates the routing of components inside the heat insulation sleeve 7. After routing, the front sleeve 22 is connected to the heat insulation sleeve 7, and finally the middle sleeve 23 is fixed to the front sleeve 22.

[0042] The heat insulation sleeve 7 has a cable routing groove 24 near the middle sleeve 23. An opening 25 is provided on the back of the heat insulation sleeve 7, and the connecting sleeve 10 is fixed to the opening 25. The first rotating block 12 and the second rotating block 13 of the rotating structure are respectively located at the upper and lower ends and the left and right sides of the opening 25.

[0043] Furthermore, the connecting sleeve 10 is provided with a wiring hole 26, and a partition plate 27 is provided in the middle of the wiring hole 26; the connecting sleeve 10 is provided with limit strips 28 on both sides of the wiring hole 26.

[0044] The design of the front sleeve 22 allows the heating element 6 inside the heat insulation sleeve 7 to first run towards the front sleeve 22, then bend through the wiring groove 24 near the middle sleeve 23 of the heat insulation sleeve 7, and then run through the wiring hole 26 on the connecting sleeve 10.

[0045] The separator 27 and the limiting strip 28 can separate and organize the wire harness, preventing the wires from getting tangled or damaged by friction, reducing the risk of short circuits and improving electrical safety.
