Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beauty and hairdressing tools, in particular to a hair straightening comb. Background Art
[0002] Hair straightening combs are widely used in the hairdressing industry to achieve hair straightening. The hair straightening comb mainly consists of an electric heating element, metal comb teeth with good heat conductivity, an external heat insulation cover, an outer shell handle, etc. The hair is straightened after passing through the heated metal comb teeth. The metal comb teeth 6 of the existing hair straightening comb are usually open from the root to the tip, and the gaps generally become wider as they go up. Figure 8 As shown in the figure, during the combing process, some hair may escape from the top of the comb teeth and escape from the straightening comb, resulting in ineffective straightening of this part of the hair. This phenomenon is particularly noticeable at the ends of the hair, as the hair volume decreases. This can negatively impact the straightening effect, requiring more time to comb hair and affecting the user experience. Utility Model Content
[0003] In view of the shortcomings of the prior art, the utility model provides a hair straightening comb with inverted hook teeth, which has a more reasonable structural design, can prevent hair from running out from the top ends of the comb teeth, and has a better hair straightening effect and user experience.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hair straightening comb with inverted hook comb teeth, comprising a housing, a heating element, and a comb tooth assembly, wherein the heating element is mounted in the housing and the comb tooth assembly is mounted on the housing, characterized in that the comb tooth assembly includes inward-retracting comb teeth and hook-shaped comb teeth, the two types of comb teeth being arranged alternately and spaced apart from each other; an inclined portion is provided on the upper side surface of the inward-retracting comb teeth, so that the upper portion of the inward-retracting comb teeth forms an inwardly retracted structure; a hook-shaped portion is provided on the upper side wall of the hook-shaped comb teeth, protruding toward the inclined portion, the hook-shaped portion protruding to approach the inward-retracting surface of the inward-retracting comb teeth and having a gap between the hook-shaped portion and the inward-retracting comb teeth, the gap forming a hair passage for hair to enter the hair straightening comb.
[0005] Furthermore, the hook-shaped portion is an angular structure, which extends toward the upper end of the inclined portion on the retracted comb teeth to cover the gap between the retracted comb teeth and the hook-shaped comb teeth.
[0006] Furthermore, a heat insulation cover is also included. The heat insulation cover is also a comb-tooth structure and is installed on the shell to cover the retracted comb teeth and the hook-shaped comb teeth.
[0007] Furthermore, hook-shaped portions are provided on both sides of the hook-shaped comb teeth, so that the gap between each retracted comb tooth and the hook-shaped comb tooth is covered by the hook-shaped portion.
[0008] Preferably, the hook-shaped comb teeth are a structure in which the left and right halves are independent of each other, and the two halves of the hook-shaped comb teeth are installed back to back in the gap between adjacent inward-retracted comb teeth.
[0009] Furthermore, a clamping ear extending upward is provided at the top end of the hook-shaped comb teeth, and the clamping ear is inserted into the heat insulation cover to achieve positioning of the hook-shaped comb teeth.
[0010] Alternatively, the hook-shaped comb teeth are an integral structure, and the hook-shaped portions are symmetrically arranged on both sides of the hook-shaped comb teeth.
[0011] Furthermore, a base plate is provided at the bottom of the hook-shaped comb teeth, connecting the hook-shaped comb teeth into an integral structure through the base plate to form an integral component; each hook-shaped comb tooth extends from between adjacent indented comb teeth, and the base plate is pressed by the bottom end of the indented comb teeth. Alternatively, each indented comb tooth extends from between adjacent hook-shaped comb teeth, and the base plate of the indented comb teeth is pressed by the bottom end of the hook-shaped comb teeth.
[0012] This utility model features a hooked portion near the tip of one of two adjacent comb teeth, while the adjacent comb teeth on the other side are recessed near the tip to form an inclined portion. These two portions are interlaced and interlocked, leaving a gap to form a hair channel for easy entry of hair. After a strand of hair enters the straightening comb through the hair channel, the hooked portion traps the hair within the gap between the teeth. The hair is then pulled out of the comb teeth after being straightened by the heated comb teeth. This ensures that all hair is straightened, effectively reducing the time spent combing hair repeatedly and enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1-4 In a first embodiment, a hair straightening comb with inverted hook teeth comprises a housing 1, a heating element, a comb assembly, and a circuit board. The heating element is connected to the circuit board and mounted together in the housing 1, and the comb assembly is mounted on the housing 1. The comb assembly comprises retracted comb teeth 2 and hooked comb teeth 3, which are arranged alternately with each other, i.e., one hooked comb tooth 3 is paired with one retracted comb tooth 2. An inclined portion 21 is provided on the upper side surface of the retracted comb teeth 2, forming an inwardly constricted structure (i.e., flat at the top and thick at the bottom) at the upper side wall of the hooked comb teeth 2. The hooked portion 31 is provided on the upper side wall of the hooked comb teeth 2, protruding toward the inclined portion 21. The hooked portion 31 protrudes to near the retracted surface of the retracted comb teeth 2, and a gap is formed between the hooked comb teeth 2 and the retracted comb teeth 2. This gap forms a hair channel 5 for hair to enter the hair straightening comb. The width of the hair channel 5 is much smaller than the gap between conventional comb teeth, thereby preventing hair from falling out. It should be noted that the definitions of directions such as up and down in the present invention are based on the state where the teeth of the hair straightening comb are facing upwards. When the viewing angle of the teeth changes, the aforementioned directions will also change accordingly.
[0023] The hook-shaped portion 31 can be an angular structure (such as one corner of a triangle or one corner of a trapezoid, with the bottom edge being a horizontal side), which is aligned with the upper end of the inclined portion 21 on the retracted comb tooth 2 and extends to cover the gap between the retracted comb tooth 2 and the hook-shaped comb tooth 3, that is, the inclined portion 21 is located below the hook-shaped portion 31.
[0024] The heat shield 4 is also provided (according to the prior art). The heat shield 4 is also in a comb-shaped structure and is mounted on the housing 1 to cover the retracted comb teeth 2 and the hook-shaped comb teeth 3 .
[0025] Hook-shaped parts 31 are provided on both sides of the hook-shaped comb teeth 3 so that the gap between each retracted comb tooth 2 and the hook-shaped comb tooth 3 is covered by the hook-shaped part 31 .
[0026] The hook-shaped comb teeth 3 are a structure in which the left and right halves are independent of each other, and the two halves of the hook-shaped comb teeth 3 are installed in the gap between the adjacent inward-retracted comb teeth 2 in a back-to-back posture.
[0027] An upwardly extending latch 32 is provided at the top end of the hook-shaped comb teeth 3 . The latch 32 is inserted into the heat insulation cover 4 so as to position the hook-shaped comb teeth 3 .
[0028] Reference Figure 4-Figure 7 In the second embodiment, the hook-shaped comb teeth 3 are an integral structure, and the hook-shaped portions 31 are symmetrically arranged on both sides of the hook-shaped comb teeth 3 .
[0029] A bottom plate 33 is provided at the bottom of the hook-shaped comb teeth 3, through which the hook-shaped comb teeth 3 are connected into an integral structure to form an integral component; each hook-shaped comb tooth 3 extends from between adjacent inward-retracted comb teeth 2, and the bottom plate 33 is pressed by the bottom end of the inward-retracted comb tooth 2.
[0030] During use, hair passes through the hair channel 5 between the hook portion 31 and the indented surface and enters the gap between the indented teeth 2 and the hooked teeth 3 for straightening. During the straightening process, although some hair may migrate to the upper portion of the gap between the indented teeth 2 and the hooked teeth 3, the hook portion 31 covers the upper portion, preventing the hair from slipping out of the upper portion. This ensures that substantially all hair is straightened, and the straightened hair can then be pulled out from the side of the straightening comb.
[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
