Description

Technical Field

[0001] The embodiments of the present application relate to the field of hair styling, in particular to a comb tooth unit and a hair styling device. Background Art

[0002] A hair straightening comb is a commonly used hair styling device in the field of hair styling, which is used for combing and styling hair. Due to the characteristics of hair being slender and soft, the comb teeth of a hair straightening comb are generally in the shape of thin rods and are regularly arranged on the hair straightening comb. In traditional hair straightening combs, the comb teeth that need to achieve the heating function are also in the shape of thin rods, and the spacing between multiple heating comb teeth is small, resulting in a large manufacturing difficulty for the heating comb teeth. Generally, a die-casting process is used to manufacture the heating comb teeth. The heating comb teeth formed by die-casting are usually integrally formed of metal and have a structure in which a comb tooth base is vertically connected to a number of parallel comb teeth.

[0003] Such heating comb teeth formed by die-casting are generally relatively thick. When the heating comb teeth are installed on the comb handle and the heating base of the heating comb teeth is in contact with the heating component to form a hair straightening comb, due to the relatively thick die-cast heating comb teeth and the need to transfer the heat of the heating element to the heating comb teeth through the comb tooth base, the heat transfer efficiency is low, and the heat loss to the heating component is also large.

[0041] The embodiments of the present application provide a comb tooth unit and a hair styling device, which achieve a high heat transfer efficiency of the comb teeth and reduce the heat loss during the heat transfer process.

[0042] First, the embodiments of the present application will describe the traditional hair straightening comb that needs to be improved. Please refer to Figure 1 , Figure 2 . Figure 1 The figure shows the structural diagram of an embodiment of a traditional hair straightening comb, where the traditional hair straightening comb includes a comb handle 110, non-heating comb teeth 120, heating comb teeth 130, a heating element, an indicator light 113, a heating power level adjustment button 112, a heating element switch button 113 and other components. And Figure 2 is Figure 1 a specific structural schematic diagram of the heating comb teeth 130 of the traditional hair straightening comb in the figure. The heating comb teeth 130 include heating comb tooth teeth 131, a comb tooth base 132, an installation structure 133, a connecting block 134 and other component structures. Among them, the heating comb teeth 131 are arranged parallel to each other and then vertically fixed on the comb tooth base 132 to form a row of heating comb tooth units; then several rows of heating comb tooth units are connected through the connecting block 134 to form the heating comb teeth 130; an installation structure 133 is also provided on the heating comb teeth 130 to facilitate the fixed connection with the comb handle 110. Among them, the non-heating comb teeth 120 are directly vertically fixed at one end of the comb handle 110, and the end of the comb handle 110 that fixes the non-heating comb teeth 120 also has a notch leading to the inside of the comb handle 110. The comb tooth base 132 of the heating comb teeth 130 is exactly adapted to be installed in this notch, so that the heating comb teeth 130 and the non-heating comb teeth 120 form the comb teeth of the traditional hair straightening comb, and the heating comb teeth 130 are fixed together with the comb handle 110 by fasteners in the comb handle 110 through the installation structure 133. It can be understood that a heating element is also installed in the comb handle 110 and contacts the comb tooth base 132 of the heating comb teeth 130. The heating element is respectively connected to the indicator light 113, the heating power level adjustment button 112, and the heating element switch button 113 through wires, so that the heating power level adjustment button 112 controls the switching of different heating powers of the heating element, and at the same time, different states of the indicator light 113 indicate different heating powers of the current heating element, and the heating power of the heating element is controlled to be turned on or off through the heating element switch button 113.

[0043] It can be seen that due to the generally thick heating comb teeth formed by die casting in the structure of the heating comb teeth 130 of the traditional hair straightening comb, and fasteners are required for fixation. When the heating comb teeth 130 are installed on the comb handle and the comb tooth base 132 of the heating comb teeth 130 contacts the heating element to form a hair straightening comb, because the heating comb teeth 130 formed by die casting are relatively thick, and the heat of the heating element needs to be transferred to the heating comb tooth teeth 131 through the comb tooth base 132, the heat transfer efficiency is low, and the heat loss of the heating components is also large.

[0044] Please refer to Figure 3 , an embodiment of the comb teeth unit of the present application. The comb teeth unit includes: comb teeth 200; the comb teeth 200 at least include a hair contact surface 210, and the hair contact surface 210 is used to contact the hair to be combed. The hair contact surface 210 is formed by a sheet metal process using a heat-conducting material. The cross-section of the comb teeth is in an inverted "U" shape, and the outer surface of the inverted "U"-shaped comb teeth has a larger surface area to fully contact the hair. Generally, the thickness of the comb teeth 200 is less than or equal to 0.6 mm, and the smaller thickness is beneficial to heat conduction and improves the heat conduction efficiency of the comb teeth unit. Further, the wall thickness of the comb teeth of the comb teeth unit is preferably uniform, which is beneficial to uniform heat conduction. Further, the comb teeth unit further includes a comb teeth fixing foot 220, and the comb teeth fixing foot 220 is fixedly connected to the comb teeth 200. Specifically, as shown in Figure 3 . After the sheet metal process forms the metal sheet-like comb teeth 200 and bends and folds them, they are fixed together with the comb teeth fixing foot 220 by welding or other means. At this time, the comb teeth unit forms two hair contact surfaces 210 that can contact the hair, and forms a cavity 211 with a certain accommodation space. The comb teeth fixing foot 220 also has a buckling portion 221, and the buckling portion 221 is used to be fixed to components such as a comb handle, so that the comb teeth unit is fixed on the comb handle to form a comb.

[0045] Please refer to Figure 4 , another embodiment of the comb teeth unit of the present application. The comb teeth unit includes: comb teeth 200; the comb teeth 200 at least include a hair contact surface 210, and the hair contact surface 210 is used to contact the hair to be combed. The hair contact surface 210 is formed by a sheet metal process using a heat-conducting material. The cross-section of the comb teeth is in an inverted "U" shape, and the outer surface of the inverted "U"-shaped comb teeth has a larger surface area to fully contact the hair. Generally, the thickness of the comb teeth 200 is less than or equal to 0.6 mm, and the smaller thickness is beneficial to heat conduction and improves the heat conduction efficiency of the comb teeth unit. Further, the wall thickness of the comb teeth of the comb teeth unit is preferably uniform, which is beneficial to uniform heat conduction. Further, the comb teeth unit further includes a comb teeth fixing foot 220, and the comb teeth fixing foot 220 is fixedly connected to the comb teeth 200. Specifically, as shown in Figure 4 . After the sheet metal process forms the metal sheet-like comb teeth 200 and bends and folds them, the two ends are respectively fixed together with a comb teeth fixing foot 220 by welding or other means. At this time, the comb teeth unit forms two hair contact surfaces 210 that can contact the hair, and forms a cavity 211 with a certain accommodation space. Each comb teeth fixing foot 220 also has a buckling portion 221, and the buckling portion 221 is used to be fixed to components such as a comb handle, so that the comb teeth unit is fixed on the comb handle to form a comb.

[0046] Further, the comb teeth unit of the embodiment of the present application can also be composed of several comb teeth 200. Please refer to Figure 5 , Figure 6, each comb tooth 200 is arranged with its head and tail connected, forming a comb tooth unit arranged with a number of comb teeth 200. The comb tooth unit in this form has a cross-section in the shape of continuous wave peaks and valleys, such as a continuous structure with a local cross-section in the shape of "U", "V", "W", or "M", etc. Further, adjacent two comb teeth can be fixedly connected through a connecting piece 230. For example, Figure 5 and Figure 6 as shown, the connecting piece 230 is rectangular. One pair of opposite sides of the rectangular connecting piece 230 is fixedly connected to the two ends of adjacent two comb teeth, and each of the other pair of opposite sides of the rectangular connecting piece 230 is fixedly connected to a comb tooth fixing foot 220. For the comb teeth without the connecting piece 230 connected at both ends, the form of the comb tooth fixing foot in the Figure 4 embodiment can be adopted. Multiple forms of comb tooth fixing feet are used in combination so that the comb tooth unit can be firmly fixed at the target position. In practical applications, comb tooth fixing feet 220 can be fixedly connected to all the rectangular connecting pieces 230, or the comb tooth fixing feet 220 can be set at intervals of a certain comb tooth distance according to the actual situation. The position and quantity of the comb tooth fixing feet are not specifically limited herein. In the comb tooth unit formed by the arrangement of a number of comb teeth 200 in this embodiment, each comb tooth has a cavity 211.

[0047] Please refer to Figure 7 、 Figure 8 , an embodiment of the hair shaping device of the present application, includes: shaping teeth 310, a heating element 340, and a comb handle 330. The shaping teeth 310 include: heating comb teeth and non-heating comb teeth 311. The heating comb teeth in this embodiment are the comb tooth units 200 mentioned in the above embodiment. This embodiment takes Figure 5 and Figure 6The comb tooth unit 200 of the embodiment is described as a heating comb tooth. The heating comb tooth 200 can be cooperatively connected with the comb handle 330 through the comb tooth fixing feet 220. The heating element 340 is fixed inside the comb handle 330, and the heating element 340 is in contact with the heating comb tooth 200 so that when the heating element 340 works, heat can be smoothly transferred to the heating comb tooth 200. The non-heating comb teeth can be directly fixedly connected to the comb handle, and the non-heating comb teeth 311 are arranged around the heating comb tooth 200 to prevent the operator from accidentally directly contacting the heating comb tooth 200 from the side, which may cause scalding. The heating element 340 here can be an electrothermal film, or a high-temperature co-fired ceramics (MCH), or a PTC heating element (ptc heater). The specific type of the heating element 340 is not limited here. It can be seen that the hair shaping device of this embodiment can straighten the hair through the shaping teeth 310. The messy hair passes through between the shaping teeth 310 and will be sorted out by the shaping teeth 310, reducing the entanglement between the hairs, and can heat the hair during the process of straightening the hair so that the internal structure of the hair changes after being heated, and then the shape of the hair is changed. After the hair cools, the shaping of the hair is achieved.

[0048] Further, please continue to refer to Figure 7 、 Figure 8 In the hair shaping device of the embodiment of the present application, the comb handle 330 can be composed of an upper body 331 and a lower body 332. Among them, the heating comb teeth 200 are arranged in a single row and vertically connected to the upper body 331, and the non-heating comb teeth 311 are arranged around the heating comb teeth 200 and vertically connected to the upper body 331. Further, the non-heating comb teeth 311 should also be higher than the heating comb teeth 200 to reduce the probability that the operator directly contacts the heating comb teeth 200 from the axial direction of the comb teeth and reduce the probability of scalding caused by the heating comb teeth 200.

[0049] Further, please refer to in combination Figure 9 、 Figure 10 、 Figure 11 、 Figure 12。The hair styling device in this embodiment further includes a comb tooth bracket 320. There is a cavity 211 between the two hair contact surfaces of the heating comb teeth. The comb tooth bracket 320 includes a bracket base 322 and a bracket closing strip 321. The bracket base 322 is perpendicularly and fixedly connected to the bracket closing strip 321. The bracket closing strip 321 is used to cooperate with the two sides of the two hair contact surfaces 210 of the heating comb teeth 200 to close the cavity 211, so as to prevent hair from entering the cavity during hair combing. The comb tooth base 322 is used to cooperate with and connect to the upper body 331. The heating comb teeth 200 are cooperatively connected to the bracket base 322 through the buckling portion 221 of the comb tooth fixing feet 220, realizing that there is no need for fasteners to connect the heating comb teeth 200 and the comb tooth bracket 320, avoiding the difficulty of disassembling and repairing when the fasteners are deformed by heat.

[0050] In one embodiment, the heating element 340 can be placed in the cavity 211 in the heating comb teeth 200. Further, the heating element 340 can be made to fit the shape of the cavity 211, thereby increasing the contact area with the heating comb teeth 200, realizing full contact between the heating element 340 and the heating comb teeth 200, and improving the heat conduction efficiency of the heating comb teeth 200. It can be understood that the heating element 340 needs to be powered by a power supply, and there is a switch 350 to control the heating element 340; the power supply, the switch 340, and the heating element 340 are connected by wires.

[0051] In another embodiment, the hair styling device further includes a heat conducting sheet 400. One side of the heat conducting sheet 400 is in contact with the connecting sheet 230 of the heating comb teeth 200, and the other side of the heat conducting sheet 400 is in contact with one side of the heating element 340. The heat conducting sheet 400 is preferably made of a material with good heat conductivity such as aluminum. The heat of the heating element 340 can be conducted to the heating comb teeth 200 through the heat conducting sheet 400. In this way, only one heating element 340 can be used to conduct heat through the heat conducting sheet to all the heating comb teeth 200, reducing the requirements for the shape and structure of the heating element 340. Further, the hair styling device can also include a heat insulating sheet 500 and a spring sheet 600; the heat insulating sheet 500 is generally a mica sheet, and the mica sheet is a material with poor heat conductivity, playing a role in insulating the comb handle 330. The spring sheet 600 has the ability of elastic deformation. One side of the heat insulating sheet 500 is used to contact the other side of the aforementioned heating element 340, the other side of the heat insulating sheet 500 then contacts one end of the spring sheet 600, and the other end of the spring sheet 600 is clamped with the lower body 332 or the bracket base 322 with a pre-tightening force. The lower body 332 and the upper body 331 are cooperatively connected to form the comb handle 330, and the comb handle 330 encloses the heating element 340, the aluminum sheet 400, the heat insulating sheet 500, and the spring sheet 600. It should be noted that in another embodiment, if the hair styling device has low requirements for heat insulation, the hair styling device in this application embodiment may not include the heat insulating sheet 500, or the heat insulating sheet 500 is a metal sheet.

[0052] The above content is an explanation of the present application in combination with specific embodiments, and it cannot be determined that the specific implementation of the present application is limited to these embodiments. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several transformations and substitutions can still be made, and in this case, it should be regarded as belonging to the protection scope of the present application.
