[0001] The utility model relates to the field of hair styling tools, in particular to a portable electric hair comb. Background Art

[0002] An electric hair comb is a hair styling tool that can solve the problem of frizzy hair, shape the hair, and create a simple curly hairstyle; due to its diverse functions, many users like to carry it with them for use when needed. However, the existing electric hair combs generally include a comb tooth part and a handle part connected to one end of the comb tooth part, such as the Chinese utility model patents CN209135569U and CN204796997U. This type of electric hair comb is relatively long and large in size, making it inconvenient to carry and use. In addition, the operating temperature of the electric hair comb reaches 130 - 200 °C. The existing electric hair combs cannot visually display whether the heating comb teeth are heating and whether the heating temperature meets the usage requirements. It is difficult for users to judge whether the temperature of the heating comb teeth is suitable for use, and it is also difficult for users to distinguish whether the heating comb teeth are in a high-temperature state. If users accidentally touch the heating comb teeth, it is easy to cause scalding accidents.

[0003] Therefore, it is necessary to provide a technical solution to solve the above problems. Summary of the Utility Model

[0015] Furthermore, avoidance recesses are provided in the middle of both sides of the comb tooth housing.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) By setting the comb tooth shell to be able to change color when the heating mechanism is heated, the temperature of the comb tooth shell will rise accordingly, and the color of the comb tooth shell will change accordingly. The user can easily find that the color of the comb tooth shell has changed, thereby intuitively reminding the user that the temperature of the comb tooth mechanism is high and that the user should not touch it, and beware of burns;

Detailed implementation manners

[0033] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0034] As Figures 1 to 9 shown, a portable electric hair comb provided by the present utility model includes a housing 1, a control circuit board 2, a heating mechanism 3 and a comb tooth mechanism 4. The comb tooth mechanism 4 is connected to the housing 1. The comb tooth mechanism 4 includes a comb tooth housing 41 and a heat-conducting metal part 43 arranged in the comb tooth housing 41. The bottom of the heat-conducting metal part 43 contacts the heating mechanism 3. At least part of the heat-conducting metal part 43 is exposed from the comb tooth housing 41. The heating mechanism 3 is electrically connected to the control circuit board 2. At least part of the comb tooth housing 41 can change color according to temperature. Preferably, the whole comb tooth housing 41 can change color according to temperature. Specifically, a temperature-sensitive color-changing plastic can be used to form the comb tooth housing 41 by injection molding. The temperature-sensitive color-changing plastic is specifically obtained by adding a temperature-sensitive color masterbatch to the plastic material. It is also possible to spray temperature-sensitive paint on the surface of the comb tooth housing 41 so that the comb tooth housing 41 can change color according to temperature. This is the prior art and will not be elaborated here.

[0035] In this embodiment, by setting the comb housing 41 to be capable of thermochromism, when the heating mechanism 3 heats up, the temperature of the comb housing 41 will also rise accordingly, and the color of the comb housing 41 will also change accordingly. It is very easy for the user to find that the color of the comb housing 41 has changed. Thus, through the color change of the comb housing 41, the user is intuitively reminded that the temperature of the comb mechanism is relatively high and cannot be touched, warning of scalding.

[0036] Furthermore, the housing 1 is connected to the comb housing 41 and a receiving cavity 5 is formed therebetween. The control circuit board 2 and the heating mechanism 3 are arranged in the receiving cavity 5. A holding portion 11 is formed on the outer surface of one end of the housing 1 away from the comb housing 41. Specifically, a plurality of insertion holes are provided at the bottom of the comb housing 41, and a plurality of insertion blocks are provided at the top end inside the housing 1. By inserting the insertion blocks into the insertion holes, the connection between the housing 1 and the comb housing 41 can be achieved.

[0037] In this embodiment, on the one hand, the interior of the housing 1 and the interior of the comb housing 41 form a receiving cavity 5, and electronic components such as the control circuit board 2 and the heating mechanism 3 can be arranged in the receiving cavity 5. On the other hand, a holding portion 11 is formed on the outer surface of one end of the housing 1 away from the comb housing 41. With such a setting, there is no need to additionally provide a holding handle, the structure is compact, the overall volume and length of the electric comb are effectively reduced, and it is convenient for the user to carry and use.

[0038] Furthermore, the heat-conducting metal part 43 includes a metal heat-conducting plate 431 and a plurality of metal heat-conducting comb teeth 432 arranged on the metal heat-conducting plate 431. The metal heat-conducting plate 431 is in contact with the heating mechanism 3, and at least part of the heat-conducting metal part 43 is capable of thermochromism. Specifically, the thermochromism function of the heat-conducting metal part is realized by setting thermochromic paint on the surface of the heat-conducting metal part 43.

[0039] In this embodiment, since during the use of the electric comb, the heat is transferred to the hair by contacting the outside hair through the heat-conducting metal part 43, therefore, by setting the heat-conducting metal part 43 to be capable of thermochromism, when the temperature of the heat-conducting metal part 43 reaches the use temperature, the heat-conducting metal part 43 will change color, thus intuitively reminding the user that the temperature of the heat-conducting metal part 43 reaches the use requirement and can be used, ensuring the use effect.

[0040] Furthermore, the comb tooth housing 41 includes a mounting seat 411, a through hole 412 for the metal heat-conducting comb tooth 432 to pass through is opened in the middle of the mounting seat 411, and a plurality of heat-insulating protective covers 413 are arranged in the middle of the mounting seat 411, each of the heat-insulating protective covers 413 is sleeved on the outer side of one of the metal heat-conducting comb teeth 432, and the surfaces on the left and right sides of each of the metal heat-conducting comb teeth 432 are exposed from the heat-insulating protective cover 413 and can contact the external hair. Specifically, during installation, a plurality of metal heat-conducting comb teeth 432 are installed from the bottom of the comb tooth shell 41 upward through the through hole 49, and each metal heat-conducting comb tooth 432 enters a corresponding heat-insulating protective cover 413, and the metal heat-conducting plate 431 remains in the accommodating cavity 5 below the comb tooth shell 41 to facilitate contact with the heating mechanism 3; the heat-insulating protective cover 413 is provided with a through hole passing through the left and right, and the heat-insulating protective cover 413 covers the outer surface of the peripheral side of the metal heat-conducting comb teeth 432, and the surfaces on the left and right sides of the metal heat-conducting comb teeth 432 are contact surfaces 4321, and the contact surfaces 4321 on both sides are exposed from both sides of the heat-insulating protective cover 413 respectively, so that the contact surface 4321 is in contact with the external hair and transfers heat to the external hair.

[0041] In this embodiment, since the contact surfaces 4321 on both sides of the metal thermal conductive comb teeth 432 are in contact with the hair during use, and the peripheral outer surfaces of the metal thermal conductive comb teeth 432 are in contact with the scalp, the peripheral outer surfaces of the metal thermal conductive comb teeth 432 are covered with a heat insulating protective cover 413, which can effectively prevent the peripheral outer surfaces of the metal thermal conductive comb teeth 432 from scalding the user's scalp during use, and the contact surfaces 4321 on both sides are respectively exposed from both sides of the heat insulating protective cover 413, which does not affect the heating effect of the contact surfaces 4321 on the hair.

[0042] Furthermore, if Figure 5 As shown, a plurality of guide comb teeth 414 are disposed on the mounting base 411 on both sides of the heat insulating protective cover 413, and the guide comb teeth 414 are staggered with the heat insulating protective cover 413. Specifically, a hair passage 46 is formed between adjacent metal heat conductive comb teeth 432, and the mounting base 411, the heat insulating protective cover 413 and the guide comb teeth 414 are integrally injection molded.

[0043] In this embodiment, by staggering the guide comb teeth 414 and the heat-insulating protective cover 413, that is, staggering the guide comb teeth 414 and the metal heat-conducting comb teeth 432, the hair can be better contacted with the contact surface 4321 of the metal heat-conducting comb teeth 432 in the hair channel 46, thereby increasing the heating area and heating uniformity of the hair, thereby improving the styling effect of the hair.

[0044] Furthermore, if Figure 4As shown, it further includes a rechargeable battery 6 disposed in the accommodating cavity 5. The rechargeable battery 6 is electrically connected to the control circuit board 2, and the control circuit board 2 is electrically connected to a charging module 7. A charging hole 12 through which the charging module 7 passes is formed on the housing 1. In this embodiment, by disposing the rechargeable battery 6 in the accommodating cavity 5, the use of this hair straightener is not restricted by the occasion, facilitating the user to use it anytime and anywhere.

[0045] Further, as Figures 4 - 5 shown, a negative ion generator 8 is also disposed in the accommodating cavity 5. The negative ion generator 8 is electrically connected to the control circuit board 2, and a plurality of negative ion discharge holes 40 are formed on the comb tooth housing 41. Specifically, negative ion generators 8 are disposed on both sides of the heating mechanism 3. Correspondingly, negative ion discharge holes 40 are disposed on both sides of the comb tooth housing 41. In this embodiment, by disposing the negative ion generator 8 and the negative ion discharge holes 40, the hair straightener also has a negative ion function.

[0046] Further, as Figure 2 shown, a switch module 21 and a status indicator light 22 are electrically connected to the control circuit board 2. A button 13 corresponding to the switch module 21 and an indicator light hole 14 corresponding to the status indicator light 22 are formed on the housing 1.

[0047] Further, it further includes a protective cover 9 covering the outside of the comb tooth mechanism 4. The protective cover 9 is snap-connected to the comb tooth housing 41. In this embodiment, since this hair straightener is suitable for being carried around and used, the user generally places it in a handbag or backpack, and the hair straightener is likely to collide with other items in the bag. Therefore, by disposing the protective cover 9, on the one hand, it can effectively prevent other items from colliding with the comb tooth mechanism 4, and on the other hand, it can effectively prevent dust or other impurities from soiling the comb tooth mechanism 4. Specifically, as Figure 3 、 4As shown in FIGS. 8 and 9, engaging grooves 47 or engaging blocks are provided at both ends of the comb-tooth housing 41, and corresponding engaging blocks 91 or engaging grooves are provided at both ends of the inner surface of the protective cover 9; avoiding recessed portions are provided in the middle of both sides of the comb-tooth housing 41. Specifically, in this embodiment, engaging grooves 47 are provided at both ends of the comb-tooth housing 41, and correspondingly, engaging blocks 91 are provided at both ends of the inner surface of the protective cover 9. When the protective cover 9 is covered on the outside of the comb-tooth mechanism 4, the engaging blocks 91 on both sides are inserted into the engaging grooves 47 on both sides, which can ensure that the protective cover 9 is firmly installed on the comb-tooth mechanism 4 and effectively prevent the protective cover from falling off due to collision. Further, in order to ensure that the protective cover 9 can be easily pulled out from the comb-tooth mechanism 4 during use, avoiding recessed portions are provided in the middle of both sides of the comb-tooth housing 41. When the protective cover 9 needs to be pulled out, the user places the thumb and index finger at the middle positions on both sides of the protective cover 9. At this time, the thumb and index finger correspond to the avoiding recessed portions on both sides. The thumb and index finger apply force to the protective cover 9. Due to the setting of the avoiding recessed portions on the comb-tooth housing 41, the middle positions on both sides of the protective cover 9 are easily moved towards the inside of the protective cover 9 under the action of the thumb and index finger, thereby causing the protective cover 9 to deform, that is, the width of the protective cover 9 becomes smaller and the length of the protective cover 9 becomes larger correspondingly, so that the engaging blocks 91 at both ends of the protective cover 9 are disengaged from the engaging grooves 47, and thus the protective cover can be easily taken out from the comb-tooth mechanism 4.

[0048] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
