[0032] The present utility model provides a hair straightener.

[0033] In the embodiments of the present utility model, as shown in the drawings, Figures 1 to 7 The hair straightener includes a main body 10 and two hair straightening components 20, the main body 10 has two clamping parts 11 that are opposite and openable and closable, and each clamping part 11 is provided with a mounting groove 111 on the side facing the other clamping part 11; each hair straightening component 20 is correspondingly arranged in one mounting groove 111, and the hair straightening component 20 includes a mounting seat 21, a ceramic heat-conducting plate 22 and a heating film 23, the ceramic heat-conducting plate 22 is mounted on the mounting seat 21, the heating film 23 is arranged on the side of the ceramic heat-conducting plate 22 facing the mounting seat 21, the mounting seat 21 is connected with the clamping part 11, and the surface of the ceramic heat-conducting plate 22 facing away from the heating film 23 is arranged towards the other mounting groove 111.

[0034] Specifically, the main body 10 is further provided with a main control board, the main control board is provided with a control circuit and other conventional circuits, the heating film 23 is provided with two wiring parts, the two wiring parts are electrically connected with the control circuit, so that the control circuit can pass current to the heating film 23, so that the heating film 23 generates heat, and the specific circuit structure will not be described here.

[0035] The semiconductor heating material (for example, an oxide semiconductor material containing one or more of zinc, aluminum, manganese, tin, cerium and yttrium) can be coated (for example, by spraying or deposition) on the inner wall of the ceramic heat-conducting plate 22 to form the heating film 23, or the heating film 23 can be attached to the ceramic heat-conducting plate 22 after the heating film 23 and the ceramic heat-conducting plate 22 are respectively formed. The ceramic heat-conducting plate 22 can be made of silicon nitride ceramic or aluminum nitride ceramic, etc. When the ceramic heat-conducting plate 22 is used as the hair straightening component 20, the ceramic material has high hardness and a smooth surface, so that the ceramic heat-conducting plate 22 can avoid additional coating and simplify the structure of the ceramic heat-conducting plate 22. Moreover, the ceramic heat-conducting plate 22 has good oxidation resistance and durability, and a long service life.

[0036] The technical scheme of the utility model installs the ceramic heat-conducting plate 22 on the mounting seat 21, and arranges the heating film 23 on the side of the ceramic heat-conducting plate 22 facing the mounting seat 21. In use, the heating film 23 generates heat and conducts heat to the ceramic heat-conducting plate 22, and the ceramic heat-conducting plate 22 clamps the hair to straighten the hair. When the heating film 23 is used as a heating element, the heating film 23 can cover the surface of the ceramic heat-conducting plate 22 as much as possible, so that the heating film 23 and the ceramic heat-conducting plate 22 have a large heat-conducting area. When the heating film 23 generates heat, the heat can be evenly conducted to the ceramic heat-conducting plate 22, so that the ceramic heat-conducting plate 22 can be uniformly heated to improve the hair straightening effect. Moreover, the heating film 23 can be directly combined with the ceramic heat-conducting plate 22, so that the fixing structure of the heating element can be reduced, and the structure of the hair straightener can be simplified.

[0037] In some embodiments, as shown in FIG. 1, Figure 5 The ceramic heat-conducting plate 22 includes a plate body 221 and two clamping portions 222 arranged on the back of the plate body 221. The two clamping portions 222 extend along the length direction of the plate body 221 and are spaced apart along the length direction of the plate body 221. The heating film 23 is located between the two clamping portions 222, and the two clamping portions 222 are clamped on the mounting seat 21. Specifically, the side surfaces of the two clamping portions 222 facing each other or away from each other are provided with protrusions or clamping grooves 223, and the mounting seat 21 is provided with clamping structures matched with the protrusions / clamping grooves 223. In this way, the hair straightener can be easily assembled.

[0038] In addition, in other embodiments, the ceramic heat-conducting plate 22 can be integrally injection molded with the mounting base 21. The heating film 23 can be arranged on the ceramic heat-conducting plate 22 first, and then the ceramic heat-conducting plate 22 and the mounting base 21 are integrally injection molded. In this way, the heating film 23 is covered, which is beneficial to reduce the risk of the heating film 23 falling off. Alternatively, the ceramic heat-conducting plate 22 and the mounting base 21 can be integrally injection molded first, and the heat-conducting surface of the ceramic heat-conducting plate 22 facing away from the heat-conducting surface of the ceramic heat-conducting plate 22 is exposed. The heating film 23 is arranged on the heat-conducting surface.

[0039] In some embodiments, the mounting base 21 includes two seat bodies 211. Each seat body 211 has a receiving groove 212, a limiting portion 213 at one end of the receiving groove 212, and a mounting opening 214 at the other end of the receiving groove 212. The two ends of the clamping portion 222 are inserted into the receiving grooves 212 of the two seat bodies 211 through the mounting openings 214 of the two seat bodies 211, respectively. The mounting openings 214 of the two seat bodies 211 are opposite to each other. Specifically, the receiving groove 212 is provided with a protrusion 216 at the groove opening, and the clamping portion 222 is provided with a clamping groove 223 on the side facing away from the other clamping portion 222. The clamping groove 223 is arranged through the two ends in the length direction of the clamping portion 222. During installation, one end of the clamping portion 222 is inserted into the receiving groove 212 of one of the seat bodies 211 first, so that the protrusion 216 of the seat body 211 is clamped into the clamping groove 223. Then, the other end of the clamping portion 222 is inserted into the receiving groove 212 of the other seat body 211, so that the protrusion 216 of the seat body 211 is clamped into the clamping groove 223. The limiting portion 213 can limit the clamping portion 222 from sliding out of the receiving groove 212. When the two seat bodies 211 are installed in the mounting groove 111, the two seat bodies 211 can be limited from sliding relative to the ceramic heat-conducting plate 22, thereby fixing the ceramic heat-conducting plate 22. In this way, the assembly stroke of the single seat body 211 and the clamping portion 222 can be reduced, which is beneficial to installation and improves the assembly efficiency of the straightening iron. The two seat bodies 211 can be in abutment or spaced apart by a certain gap. Of course, in other embodiments, the mounting base 21 can be integrally arranged, and the mounting base 21 is provided with a mounting opening at one end for inserting the clamping portion 222.

[0040] In some embodiments, the opposite sides of the mounting groove 111 are provided with limiting grooves 112, and each limiting part 213 is provided with a clamping protrusion 215 located in the limiting groove 112. Specifically, the clamping part 11 comprises a bottom shell 113 and a cover plate 114 covering the bottom shell 113, and the cover plate 114 of any clamping part 11 is located on the side of the bottom shell 113 facing the other clamping part 11, the mounting groove 111 is located on the end side of the cover plate 114, and the part of the cover plate 114 close to the mounting groove 111 and the bottom shell 113 forms a limiting groove 112, and the part of the bottom shell 113 located on the side of the mounting groove 111 and opposite to the cover plate 114 has a limiting groove 112, i.e. the opposite sides of the mounting groove 111 in the length direction of the clamping part 11 are provided with limiting grooves 112. During installation, the mounting seat 21 is first installed in the mounting groove 111, and then the cover plate 114 is covered on the bottom shell 113, so that the mounting seat 21 can be fixed in the mounting groove 111. The structure of fixing by the clamping protrusion 215 and the limiting groove 112 is simple and reliable, and is convenient for assembly. The clamping part 11 adopts the form of the bottom shell 113 and the cover plate 114, and during installation, the hair straightening part 20 and other components such as the main control board can be installed in the bottom shell 113 first, and then the cover plate 114 is installed, which is convenient for the assembly of the hair straightener.

[0041] Of course, in other embodiments, the seat body 211 can be locked in the clamping part 11 by screws. In addition, in other embodiments, the clamping part 11 comprises a lower shell and an upper shell, and the upper shell of any clamping part 11 is located on the side of the lower shell facing the other clamping part 11, and the mounting groove 111 is formed between the upper shell and the lower shell, i.e. the opening of the mounting groove 111 is located on the upper shell, the bottom wall of the mounting groove 111 is located on the lower shell, and the limiting grooves 112 are respectively formed between the lower shell and the upper shell and on the opposite sides of the mounting groove 111.

[0042] In addition, in other embodiments, in combination with the above description Figure 6 and Figure 7The clamping portion 222 is located on the side of the ceramic heat-conducting plate 22 and has a clamping groove 223, and the mounting seat 21 has a protrusion 216 clamped in the clamping groove 223. Specifically, the clamping groove 223 is located between the front surface (the outer surface for contacting the hair) and the back surface of the ceramic heat-conducting plate 22, and the width of the clamping groove 223 along the thickness direction of the ceramic heat-conducting plate 22 is smaller than the thickness of the ceramic heat-conducting plate 22, that is, the clamping groove 223 is arranged by using the space of the side of the ceramic heat-conducting plate 22. The seat body 211 has a containing groove 212, a limiting portion 213 located at one end of the containing groove 212, and a mounting opening 214 located at the other end of the containing groove 212, and the containing groove 212 is provided with the protrusion 216 at the slot opening. The clamping groove 223 is arranged through both ends in the length direction of the ceramic heat-conducting plate 22. During installation, one end of the ceramic heat-conducting plate 22 can be inserted into the containing groove 212 of one of the seat bodies 211, so that the protrusion 216 of the seat body 211 is correspondingly clamped into the clamping groove 223 on the side of the ceramic heat-conducting plate 22, and the other end of the ceramic heat-conducting plate 22 is inserted into the containing groove 212 of the other seat body 211, and the protrusion 216 of the seat body 211 is also correspondingly clamped into the clamping groove 223. In this way, the structure of the ceramic heat-conducting plate 22 can be simplified, the sintering of the ceramic heat-conducting plate 22 is facilitated, and the yield of the ceramic heat-conducting plate 22 is improved.

[0043] With reference to Figures 1 to 6 In some embodiments, the hair straightener further comprises a temperature sensing element, a spring sheet 31, and a buffer 32, the temperature sensing element is located between the spring sheet 31 and the heating film 23, the side of the spring sheet 31 away from the temperature sensing element abuts against the buffer 32, and the buffer 32 is clamped to the clamping portion 222. That is, by limiting the spring sheet 31 through the buffer 32, the pressure of the spring sheet 31 on the mounting seat 21 can be reduced, thereby reducing the risk of deformation or damage of the mounting seat 21 due to excessive force, and improving the reliability of the hair styling component 20. In some embodiments, the thickness of the clamping protrusion 215 along the depth direction of the mounting groove 111 is greater than the height of the limiting groove 112 along the depth direction of the mounting groove 111. Alternatively, the buffer 32 is a metal piece, so that the size of the buffer 32 can be reduced, and the occupied space of the buffer 32 on the hair styling component 20 can be reduced.

[0044] In some embodiments, the side of the mounting seat 21 away from the ceramic heat-conducting plate 22 has a movable space 115 with the bottom wall of the mounting groove 111, and the hair straightener further comprises a resilient member 33, which is located in the movable space 115 and abuts between the mounting seat 21 and the clamping portion 11. That is, when the ceramic heat-conducting plate 22 is pressed down, the mounting seat 21 and the ceramic heat-conducting plate 22 can move into the movable space 115 against the elastic force of the resilient member 33, so that when the hair straightening operation is performed, the two ceramic heat-conducting plates 22 can effectively adhere to the hair, and the friction with the hair can be reduced. The resilient member 33 can be a spring or a rubber block, etc.

[0045] In some embodiments, the number of elastic members 33 is multiple, and the multiple elastic members 33 are distributed along the length direction of the ceramic heat-conducting plate 22. In this way, the hair iron 20 can be uniformly stressed, and the structure of the single elastic member 33 can be simplified.

[0046] In some embodiments, the bottom wall of the mounting groove 111 is provided with a positioning groove, and the elastic member 33 is arranged in the positioning groove. In this way, the elastic member 33 can be conveniently positioned and mounted, and the elastic member 33 can be effectively limited to avoid displacement of the elastic member 33 during use.

[0047] In some embodiments, the two clamping portions 11 are hinged to each other at the ends away from the mounting groove 111, and the two clamping portions 11 are provided with a reset spring 12, and the reset spring 12 has elastic deformation to drive the two clamping portions 11 to move away from each other. In this way, the opening range of the two clamping portions 11 can be large, and the user can use conveniently. Of course, in other embodiments, the main body 10 further includes a handle, one of the two clamping portions 11 is connected to the handle as a whole, and the handle and the clamping portion 11 are provided with a mounting position, and the other clamping portion 11 is hinged to the mounting position.
