[0045] The present invention is described in detail below with reference to the accompanying drawings.

[0046] like Figure 1-8 As shown, a multifunctional hair straightening comb with heating and vibration comprises a shell 1, wherein the shell 1 comprises an upper shell 11 and a lower shell 12 which are spliced ​​to each other, wherein a power supply battery 13 and a power supply circuit board 14 for supplying power to a metal heat conductive sheet 17 are arranged in the shell 1, wherein the upper shell 11 is provided with a mounting groove 41, wherein a comb tooth module is installed in the mounting groove 41.

[0047] The comb tooth module includes a plurality of metal heat-conducting teeth 3 and heat-insulating teeth 20 sleeved on the metal heat-conducting teeth 3. The heat-insulating teeth 20 are hollow structures. The heat-insulating teeth 20 include a heat-insulating head 21 sleeved on the end of the metal heat-conducting teeth 3 and a heat-insulating connecting strip 22 attached to the side of the metal heat-conducting teeth 3. The heat-insulating head 21 and the heat-insulating connecting strip 22 can prevent the metal heat-conducting teeth 3 from directly contacting the skin, thereby reducing damage to the hair. In addition, when the comb tooth module 2 contacts the hair and scalp, the vibration motor 53 can be used to stimulate the hair follicles and massage the scalp.

[0048] The heat-insulating teeth 20 and the metal heat-conducting teeth 3 are spliced ​​to form an integrated columnar structure; the metal heat-conducting teeth 3 will not protrude outward and will not be exposed. When combing the hair, the hair, skin, etc. will not come into direct contact with the metal heat-conducting teeth 3. The heat is conducted through the heat-insulating connecting strips 22 and the heat-insulating head 21, which effectively protects the hair.

[0049] Furthermore, a connecting protrusion 31 is formed on the outer end of the metal thermally conductive tooth 3, and a connecting groove 25 which cooperates with the connecting protrusion 31 is formed on the inner side of the thermal insulation head 21; when the thermal insulation tooth 20 is spliced ​​with the metal thermally conductive tooth 3, the thermal insulation head 21 is connected to the connecting protrusion 31 of the metal thermally conductive tooth 3 through the connecting groove 2525, and the thermal insulation tooth 20 sleeved on the metal thermally conductive tooth 3 can be stably connected to the metal thermally conductive tooth 3. When combing the hair, the thermal insulation tooth 20 is not easy to fall off the metal thermally conductive tooth 3, thereby ensuring the stability of the connection and better thermal insulation effect.

[0050] Furthermore, a first connecting end face 33 is formed at the outer end of the metal heat-conducting tooth 3, a connecting protrusion 31 is formed on the first connecting end face 33, a second connecting end face 34 is formed on the heat-insulating head 21, and a connecting groove 25 is formed on the second connecting end face 34; the metal heat-conducting tooth 3 can be in surface contact with the second connecting end face 34 of the heat-insulating head 21 through the first connecting end face 33, and a part of the heat of the metal heat-conducting tooth 3 can be transferred to the heat-insulating head 21. When the heat-insulating head 21 contacts the hair scalp, it has a heat-conducting effect, which not only prevents the metal heat-conducting tooth 3 from contacting the hair scalp, but also has a heating effect, and the combing effect is better.

[0051] In one embodiment, there is a buffer gap between the first connection end face 33 and the second connection end face 34, so as to prevent the heat of the metal heat-conducting teeth 3 from being transferred to the tip of the heat-insulating head 21 through the tip of the metal heat-conducting teeth 3, thereby preventing damage to the scalp. At the same time, the gap also allows the heat-insulating teeth 20 to have a certain movable distance, so that there is a certain movement buffer when the heat-insulating head 21 contacts the scalp to avoid damage to the scalp. After the buffer contact, the metal heat-conducting teeth 33 are in surface contact with the second connection end face 34 of the heat-insulating head 21 through the first connection end face 33, and part of the heat of the metal heat-conducting teeth 3 can be transferred to the heat-insulating head 21, and part of the heat of the metal heat-conducting teeth 3 can be transferred to the heat-insulating head 21, when the heat-insulating head 21 contacts the hair scalp.

[0052] Furthermore, the heat-insulating head 21 is formed with an arc surface 23 that contacts the scalp and hair; the outer ring curvature of the heat-insulating teeth 20 is adapted to the outer ring curvature of the metal heat-conducting teeth 3; the heat-insulating teeth 20 are connected at the tips to form a virtual arc surface, thereby improving the hair drying effect.

[0053] In order to further facilitate the combing effect, the heat-insulating teeth 20 are flat and oval in shape, which provides a better combing effect.

[0054] The heat-insulating connecting strip 22 is formed with a guide protrusion 24 protruding inwardly along the length direction, and the side of the metal heat-conducting tooth 3 is formed with a guide groove 32 matched with the guide protrusion 24 along the length direction. Thus, the metal heat-conducting tooth 3 is limited in the horizontal direction to prevent the metal heat-conducting tooth 3 from shaking left and right, and to prevent the metal heat-conducting tooth 3 from shaking left and right to cause a gap between the metal heat-conducting tooth 3 and the heat-insulating tooth 20, thereby causing a hair jam phenomenon.

[0055] The comb tooth module 2 also includes a metal plate 35 for mounting the metal heat-conducting teeth 3 and a heat-insulating plate 36 for mounting the heat-insulating teeth 20; the metal plate 35 and the heat-insulating plate 36 are both mounted on the mounting groove 41 of the housing 1. During installation, the heat-insulating plate 36 is sleeved on the metal heat-conducting teeth 3 of the metal plate 35 through the molded heat-insulating teeth 20, and at this time, the guide protrusions 24 molded on the heat-insulating connecting strip 22 are slidably matched with the guide grooves 32 of the metal heat-conducting teeth 3 to achieve a sliding connection, until the connecting protrusions 31 at the ends of the metal heat-conducting teeth 3 are embedded in the connecting grooves 25 of the heat-insulating head 21, to achieve a positioning connection, which can prevent the metal heat-conducting teeth 33 from being limited in the horizontal direction and prevent the metal heat-conducting teeth 3 from shaking left and right.

[0056] The metal heat-conducting teeth 3 are aluminum alloy heat-conducting teeth, and the heat-insulating teeth 20 are nylon comb teeth. In the present invention, the aluminum alloy comb teeth can be replaced with comb teeth of other heat-conducting materials, that is, it can realize the heat transfer of the heating plate to the heating arc surface for heating. The nylon comb teeth are replaced with heat-insulating comb teeth such as plastic comb teeth, that is, the heat cannot be transferred to the insulating comb teeth, thereby achieving a heat-insulating effect.

[0057] Furthermore, a connecting structure 4 is provided between the heat insulating plate 36 and the mounting groove 41, and the connecting structure 4 includes an engaging block 42 formed transversely at the bottom of the heat insulating plate 36, an outer side wall of the engaging block 42 is formed with an inwardly concave engaging groove 43, and the mounting groove 41 is provided with a clamping block 44 capable of elastically clamping the engaging block 42, the clamping block 44 can be embedded in the clamping groove 43, and a side sliding groove 45 for the engaging block 44 to slide is formed transversely on the side wall of the mounting groove 41; a guiding inclined surface 46 for sliding cooperation with the bottom surface of the engaging block 42 is formed on the top of the clamping block 44, a guide column 47 is connected to the inner end of the clamping block 44, and a compression spring 48 is provided on the side sliding groove 45, and the compression spring 48 can drive the engaging block 44 to pop out a part transversely outward; a transverse guide hole 49 for the guide column 47 to slide is formed transversely through the shell 1, and the outer end of the guide column 47 extends outward. In this embodiment, when the heat insulation board 36 needs to be installed in the installation groove 41, the engaging block 42 of the heat insulation board 36 will press down the engaging block 44, and the engaging block 44 will retreat into the side sliding groove 45 under the action of the guide inclined surface 46. After being installed in place, the engaging block 44 will extend into the installation groove 41 under the elastic action of the compression spring 48, and the engaging block 44 will be embedded in the engaging groove 43 of the engaging block 42 to lock the engaging block 42, and the comb module 2 is installed. When the comb module 2 needs to be disassembled, the guide column 47 is pulled to disengage the engaging block 44 from the engaging groove 43 of the engaging block 42. At this time, the comb module 2 can be taken out from the installation groove 41 to achieve disassembly; after disassembly, the style of the comb module 2 can be changed, and the practicality is further improved.

[0058] In this embodiment, the installation groove 41 is detachably mounted with a shielding cover 37 . After the comb tooth module 2 is disassembled, the shielding cover 37 can be installed to prevent the heating component in the installation groove 41 from being exposed and causing burns.

[0059] A vibration device 5 is also provided in the shell 1. The vibration device 5 includes a mounting base plate 51 arranged on the lower shell 12. The mounting base plate 51 is provided with an upright positioning column 52. The number of the positioning columns 52 is multiple, and two adjacent positioning columns 52 are arranged at intervals. The mounting base plate 51 is provided with a vibration motor 53 installed by the positioning column 52. The lower shell 12 is also provided with a pressing plate 54. The pressing plate 54 is formed with a positioning hole 55 that cooperates with the positioning column 52 and an arc groove 56 that cooperates with the vibration motor 53. An eccentric wheel 57 is installed at the driving end of the vibration motor 53. When the eccentric wheel 57 rotates, it can contact the shell 1 to drive the shell 1 to vibrate; the vibration motor 53 rotates under the power supply of the battery, thereby driving the eccentric wheel 57 installed at the driving end to rotate, realizing vibration, and driving the shell 1 to vibrate. When the comb tooth module 2 contacts the scalp, it has a better massage effect and maintains the hair.

[0060] The shell 1 will vibrate when driven by the vibration motor 53.
