DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0028] Referring to Figures 1 to 10 The heat-conducting comb tooth device of the electric heating straightening comb for heat-pulling hair includes a handle 1, a comb handle 2 arranged at the front end of the handle 1, a slot hole 21 horizontally and through arranged on one side of the comb handle 2, two groups of heating modules 3 arranged in parallel along the long edge direction of the comb handle 2 in the comb handle 2, a plurality of groups of fixed heat-pulling modules 4 arranged vertically on the comb handle 2 and equidistantly along the long edge direction of the comb handle 2, a movable heat-pulling module 5 arranged in parallel along the long edge direction of the comb handle 2 in the comb handle 2, and the movable heat-pulling module 5 being provided with a plurality of groups of movable comb teeth 51 and an adjusting unit 52 capable of synchronously driving the plurality of groups of movable comb teeth 51 to horizontally approach or move away from the fixed heat-pulling modules 4.

[0029] The plurality of groups of movable comb teeth 51 are arranged vertically on the comb handle 2 and staggered with the plurality of groups of fixed heat-pulling modules 4.

[0030] Before using the electric heating straightening comb to heat-pull and style hair, the device needs to be connected to an external power source first, and the heating module 3 is driven to work. The heating module 3 generates stable heat energy in the working state, and synchronously transmits the heat energy to the fixed heat-pulling module 4 and the movable heat-pulling module 5, so that the two are quickly heated until the preset heat-pulling temperature is reached, thereby meeting the heating and shaping needs of the hair. After heating is completed, the user can realize smooth clamping and straightening of the hair through the coordinated cooperation between the fixed heat-pulling module 4 and the movable heat-pulling module 5.

[0031] In the hot drawing process, if the comb tooth spacing does not match the current hair bundle thickness, the working gap between the comb teeth needs to be dynamically adjusted. The driving unit arranged on one side of the movable hot drawing module 5 can be directly driven to work. After the driving unit acts, the synchronous belt drives multiple movable hot drawing modules 5 to move in the horizontal direction, so that the movable hot drawing modules 5 as a whole move closer to or farther away from the fixed hot drawing module 4, thereby realizing accurate adjustment of the spacing between the comb teeth. Through this adjustment mode, the working spacing can be flexibly set according to the thickness of the hair volume, the user's needs or styling preferences, ensuring that the hair bundle is evenly heated and stably clamped during each drawing process, improving the drawing effect while avoiding problems such as tangling and damage caused by uneven heating.

[0032] Referring to Figure 8 and Figure 9 As shown in the drawings: the fixed hot drawing module 4 is provided with fixed comb teeth 41 capable of hot drawing hair and a quick release unit 42 capable of detachably arranging the fixed comb teeth 41 on the comb handle 2; the fixed comb teeth 41 are detachably arranged on the comb handle 2 in a vertical state through the quick release unit 42; and the quick release unit 42 is embeddedly installed in the slot hole 21.

[0033] The fixed comb teeth 41 are arranged on the holder 1 body in a detachable and movable connection manner through the quick release unit 42, so that the fixed comb teeth 41 can be quickly installed or detached according to the user's needs. The arrangement of this structure not only facilitates the user's operation during daily maintenance and cleaning, but also makes it possible to adjust the arrangement density of multiple groups of fixed comb teeth 41. When the user wants to adjust the spacing between the comb teeth to adapt to different thickness, sparseness or styling requirements of the hair, the user only needs to rearrange the fixed comb teeth 41 through the quick release unit 42 to accurately adjust the transverse position of the fixed comb teeth 41, thereby flexibly setting the required comb tooth density distribution and improving the personalized adaptation ability of the hot drawing comb.

[0034] During the hair hot drawing operation, the heating module 3 first enters the working state to generate heat, and efficiently conducts the heat to the fixed comb teeth 41, so that the fixed comb teeth 41 are heated to a preset working temperature in a short time. The heated fixed comb teeth 41 can directly contact the hair, and heat treat the clamped hair bundle by means of the uniform and stable heat output on the surface of the fixed comb teeth 41, so as to promote the hair to be straightened and styled in a heated state, and finally achieve the effect of smooth and straight styling.

[0035] Referring to Figure 8 As shown in the drawings: the fixed comb teeth 41 are composed of a first tooth plate 411 arranged in a U shape and a first heat conducting sheet 412 embeddedly installed in the first tooth plate 411; and the bottom of the first tooth plate 411 is further provided with a first sliding groove 413 and a through hole 414 capable of allowing the adjustment unit 52 to pass through.

[0036] The first sliding groove 413 is provided with two positions, and the two positions of the first sliding groove 413 are oppositely and penetratingly arranged on the bottom of the first tooth plate 411; the heat conduction sheet is closely assembled in the first tooth plate 411 in an embedded manner, and the bottom of the first heat conduction sheet 412 is flush with the bottom of the first tooth plate 411 through precise fitting, so as to form an integrated heat transfer structure, and avoid uneven heat dissipation or energy loss caused by uneven heat conduction surface.

[0037] During the installation process, when the first heat conduction sheet 412 is accurately buckled on the heating surface of the heating module 3, the heat energy generated by the heating module 3 can be efficiently conducted to the first heat conduction sheet 412 through the contact surface. Since the first heat conduction sheet 412 is made of an alloy material with excellent heat conduction performance and forms a good thermal coupling interface with the heating module 3, it can ensure that the heat is evenly spread to all parts of the first tooth plate 411 in a short time.

[0038] With the rise of the temperature of the first heat conduction sheet 412, the first tooth plate 411 embedded therein is also gradually heated, and after being heated to a preset target temperature, synchronous heating of the entire first tooth plate 411 area is realized. When the user uses the first tooth plate 411 to perform a hair straightening operation, the first tooth plate 411 can apply heat energy to the hair fibers through continuous and stable heat output, thereby achieving a fast and uniform straightening and styling effect.

[0039] Referring to Figure 8 As shown in the figure, the two sides of the fixed comb teeth 41 are also respectively embeddedly installed with a fixed magnetic attraction block 415 and a movable magnetic attraction block 416 which can cooperate with the quick release unit 42 to quickly release the fixed comb teeth 41.

[0040] The fixed magnetic attraction block 415 is embeddedly installed on one side of the fixed comb teeth 41, and the movable magnetic attraction block 416 is movably embeddedly installed on the other side of the fixed comb teeth 41 and can move horizontally along the long side of the fixed comb teeth 41.

[0041] When it is necessary to self-adjust the installation position of the fixed comb teeth 41, it is only necessary to take the required fixed comb teeth 41 according to the heat stretching demand and insert and place them in the corresponding position. When the fixed comb teeth 41 are inserted into the corresponding position in the comb handle 2, it is necessary to further lock the fixed comb teeth 41 to ensure that the fixed comb teeth 41 will not be separated from the comb handle 2, at which time it is only necessary to drive the quick release unit 42 to act in cooperation with the fixed magnetic attraction block 415 and the movable magnetic attraction block 416 to lock the fixed comb teeth 41 in the comb handle 2.

[0042] Referring to Figure 9As shown: the quick release unit 42 includes a fixed magnetic strip 421, a movable magnetic strip 422 and a locking piece 423; the movable magnetic strip 422 is embeddedly installed in the slot hole 21; the locking piece 423 is screw-connected to the outside of the movable magnetic strip 422, used to lock the movable magnetic strip 422 and the comb handle 2; the fixed magnetic strip 421 is embeddedly installed in the other side inner wall of the comb handle 2 relative to the movable magnetic strip 422.

[0043] When it is needed to flexibly adjust the installation position of the fixed comb teeth 41 to adapt to different hair volume or styling needs, the user first inserts the plug-in end of the fixed comb teeth 41 into the comb handle 2. At this time, the fixed magnetic block 415 and the movable magnetic block 416 arranged on both sides of the fixed comb teeth 41 are respectively butted against the fixed magnetic strip 421 and the movable magnetic strip 422 on the inside of the comb handle 2, and the preliminary positioning of the fixed comb teeth 41 is realized through magnetic attraction.

[0044] The fixed comb teeth 41 are stably magnetically attracted by the fixed magnetic strip 421 and the movable magnetic strip 422, ensuring that the fixed comb teeth 41 will not be loose or fall off in the normal use state; and the movable magnetic block 416 is designed to be slidably arranged along the long edge direction of the fixed comb teeth 41 and works together with the movable magnetic strip 422. After the fixed comb teeth 41 are inserted into the comb handle 2, the magnetic force generated by the movable magnetic strip 422 attracts and drives the movable magnetic block 416 to automatically slide close to the movable magnetic strip 422, and makes the movable magnetic block 416 and the movable magnetic strip 422 be attracted at the same time and be clamped in the slot hole 21, realizing the effect that the two magnetic blocks are tightly attracted to the corresponding magnetic strips at the same time, thereby enhancing the installation stability of the fixed comb teeth 41 in the comb handle 2.

[0045] If the user needs to replace or re-adjust the spacing position of the fixed comb teeth 41, he only needs to manually loosen the locking piece 423 between the movable magnetic strip 422 and the comb handle 2, so as to release the limiting connection of the movable magnetic strip 422. After releasing, remove the movable magnetic strip 422 and tilt the comb handle 2, so that the movable magnetic block 416 is retracted into the body of the fixed comb teeth 41, and the magnetic attraction state is released, so as to realize the purpose of smoothly pulling out the fixed comb teeth 41 from the comb handle 2. Without the aid of tools, the fixed comb teeth 41 can be disassembled or replaced, greatly improving the use convenience and structural maintainability.

[0046] Referring to Figure 4 and Figure 10 As shown: the movable comb teeth 51 are composed of a second tooth plate 511 arranged in a U shape and a second heat-conducting sheet 512 embeddedly installed in the second tooth plate 511; the bottom of the second tooth plate 511 is further provided with a second sliding groove 513 and a screw hole 514 capable of being screw-connected with the driving end of the adjusting unit 52; the second tooth plate 511 is slidably arranged on the heating module 3 through the second sliding groove 513.

[0047] Since the movable combs 51 are arranged in multiple groups and staggered and spaced apart from the multiple groups of fixed combs 41, when it is necessary to adjust the spacing between the movable combs 51 and the fixed combs 41, only the driving unit needs to be actuated, and the driving unit in the working state will synchronously drive the movable combs 51 to move closer to or away from the fixed combs 41 along the horizontal axis direction, so as to realize flexible adjustment of the spacing between the movable combs 51 and the fixed combs 41. This structure allows users to make personalized adjustments according to different hair quality, hair volume and styling needs, so that the comb gap is always in the optimal matching state.

[0048] Referring to Figure 10 As shown: the adjusting unit 52 is provided with an adjusting rod 521 capable of synchronously adjusting multiple groups of movable combs 51 and an adjusting piece 522 capable of driving the adjusting rod 521 to adjust; the adjusting rod 521 is arranged in parallel along the long edge direction of the handle 1 in the handle 1 and is screwed with the screw holes 514 of multiple groups of movable combs 51; the adjusting piece 522 is coaxially fixedly arranged at one end of the adjusting rod 521 close to the handle 1.

[0049] When it is necessary to adjust the spacing between multiple groups of movable combs 51 and fixed combs 41, the staff only needs to manually hold and rotate the adjusting piece 522, which will synchronously drive the adjusting rod 521 connected thereto to act during rotation; in the rotating state, the adjusting rod 521 drives multiple groups of movable combs 51 screwed thereto to move synchronously through the threaded connection mechanism, realizing the adjustment operation of the movable combs 51 moving closer to or away from the fixed combs 41 along the horizontal direction. This structure enables the movable combs 51 to complete precise and unified displacement adjustment according to the operation needs on the basis of maintaining staggered arrangement, thereby realizing linkage adjustment of the spacing between the movable hot stretching module 5 and the fixed hot stretching module 4.

[0050] This structure realizes synchronous adjustment of multiple groups of movable combs 51 through the adjusting piece 522 linkage adjusting rod 521, so that the comb spacing adjustment operation is simple and synchronous, significantly improving the overall adjustment accuracy and efficiency, meeting the individual needs of different hair volume or hair quality for temperature contact surface and clamping force during hot stretching, and improving the consistency and comfort of straightening.

[0051] The adjusting unit 52 is not limited to the above structure, but can also be other structures for the purpose of synchronously driving multiple groups of movable combs 51 to move horizontally.

[0052] Referring to Figure 6 As shown: the heating module 3 is provided with two groups of first heating strips 31 and second heating strips 32 capable of continuously heating; the first heating strips 31 and the second heating strips 32 are arranged in parallel relative to each other in the comb handle 2.

[0053] When it is necessary to synchronize the heating of the fixed heat-drawing module 4 and the movable heat-drawing module 5 after the distance adjustment is completed, the user only needs to turn on the heating switch, and the first heating strip 31 and the second heating strip 32 are powered by the power supply system. At this time, the first heating strip 31 and the second heating strip 32 start working and generate heat energy, and respectively conduct heat to the fixed heat-drawing module 4 and the movable heat-drawing module 5 in thermal contact with them. Because the two are in close thermal conduction contact with the corresponding heating strips, efficient absorption and transmission of heat energy can be achieved. As the heating process continues, the temperature of the fixed heat-drawing module 4 and the movable heat-drawing module 5 will gradually rise until the set preheating temperature is reached, and the system can control the heating to stop through the temperature control unit, thereby completing the rapid preheating process of the whole heat-drawing assembly.

[0054] Preferably, the first heating strip 31 and the second heating strip 32 adopt an electromagnetic coil structure to generate heat energy through electromagnetic induction, avoiding the problem of exposed heating bodies in the traditional resistance heating method and effectively reducing the risk of direct scalding or burning of hair by high-temperature elements during contact.

[0055] The comb teeth of the present application can self-adjust the heating distance according to the heating demand, which is convenient to operate and has good effect.

[0056] The above examples only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
