Description

Technical Field

[0001] This utility model relates to the technical field of hair care, and in particular to an adjustable tightness hair comb. Background Technology

[0002] In the modern hairdressing industry, perming combs are a common hair styling tool widely used in daily home hairdressing and professional hair salons. Their main function is to help create straight hair, various curls, waves and other hairstyles by combing the hair and using heat or chemical action, which greatly satisfies people's pursuit of personalized hairstyles.

[0003] However, existing perming combs have the following shortcomings in practical use: Combs with a fixed tooth spacing cannot flexibly adjust the clamping force according to different hair volumes. For those with a lot of hair, the fixed and narrow tooth spacing results in excessive clamping force, over-compressing the hair. This not only makes it difficult to stably hold a large amount of hair but also causes uneven stress and damage to the hair, preventing the heat or chemical action from being evenly applied to each strand, thus reducing the uniformity of the perm. For those with less hair, the fixed and wider tooth spacing results in insufficient clamping force, making it difficult to stably hold a small amount of hair between the teeth. During the perming process, this hair can easily loosen and escape the control of the teeth, preventing the heat or chemical action from fully penetrating and making it difficult to create a clear and lasting curl, severely affecting the perming effect. Therefore, existing combs cannot be adapted to people with different hair volumes, resulting in poor perming results. In view of this, the adjustable-tension hair comb of this application is proposed. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0039] like Figures 1 to 12 As shown, in one embodiment, an adjustable hairbrush 1 includes a base 20 and an adjustment assembly. The adjustment assembly includes a comb base 32, a comb block 33, and an elastic element 34. The comb base 32 is disposed on the base 20. The comb base 32 is provided with a plurality of equidistantly distributed first comb teeth 320. The comb block 33 is slidably disposed on the comb base 32. The comb block 33 is provided with a plurality of equidistantly distributed second comb teeth 330. Each first comb tooth 320 and each second comb tooth 330 are arranged alternately. Under the action of an external force, the comb block 33 slides relative to the comb base 32 so that the interval between each second comb tooth 330 and each first comb tooth 320 is adjustable. The elastic element 34 is sleeved on the comb base 32. The elastic element 34 is used to push the comb block 33 to drive each second comb tooth 330 away from each first comb tooth 320.

[0040] It should be noted that the comb holder 32 is disposed on the base 20, and a plurality of first comb teeth 320 are disposed on the upper surface of the comb holder 32 away from the base 20, and each of the first comb teeth 320 is distributed in a rectangular array at equal intervals. The comb block 33 is slidably disposed on the comb holder 32, and a plurality of second comb teeth 330 are disposed on the upper surface of the comb block 33 away from the comb holder 32, and each of the second comb teeth 330 is distributed in a rectangular array at equal intervals, and a row of second comb teeth 330 is located between two adjacent rows of first comb teeth 320, so that each row of first comb teeth 320 and each row of second comb teeth 330 are arranged alternately. Furthermore, one end of the comb block 33 extends from one end face of the comb base 32, and the elastic element 34 is sleeved on the comb base 32. The elastic element 34 is a spring structure, and the two ends of the elastic element 34 respectively abut against the end face of the comb base 32 and the end of the comb block 33 that extends out of the comb base 32 so that the comb block 33 drives each second comb tooth 330 to move away from each first comb tooth 320 on the comb base 32 in a corresponding manner.

[0041] It should be noted that when the user needs to comb their hair, the push comb block 33 extends from the end of the comb base 32 to bring the second comb teeth 330 closer to each of the first comb teeth 320, making the spacing between each of the second comb teeth 330 and each of the first comb teeth 320 adjustable. Simultaneously, the comb block 33 compresses the elastic element 34. This allows the user to flexibly adjust the clamping force according to the amount of hair, ensuring that heat is evenly applied to each strand of hair, thereby improving the perming effect. Furthermore, after the user finishes combing their hair, they release the force of the push comb block 33. Under the elastic force of the elastic element 34, the elastic element 34 moves the push comb block 33 away from the comb base 32, causing each of the second comb teeth 330 to return to its initial position away from the first comb teeth 320, allowing the user to quickly begin the next combing action, thus improving combing efficiency. In this way, the adjustable tightness hairbrush 1 of this application can adjust the interval between the second comb tooth 330 and the first comb tooth 320 to suit people with different hair volumes for comfortable hair combing, thereby improving the combing effect.

[0042] like Figure 9 As shown, in one embodiment, the comb holder 32 has a groove 321, and each first comb tooth 320 is disposed at intervals on the inner bottom wall of the groove 321.

[0043] It should be noted that the comb holder 32 is mounted on the base 20. A plurality of first comb teeth 320 are arranged on the upper surface of the comb holder 32 away from the base 20, and each first comb tooth 320 is arranged in a rectangular, equidistant array. The comb block 33 is slidably mounted on the comb holder 32. A plurality of second comb teeth 330 are arranged on the upper surface of the comb block 33 away from the comb holder 32, and each second comb tooth 330 is arranged in a rectangular, equidistant array. A row of second comb teeth 330 is located between two adjacent rows of first comb teeth 320, thus ensuring that each row of first comb teeth 320 and each row of second comb teeth 330 are arranged in a staggered pattern. Further, as... Figure 6 As shown, in one embodiment, the comb block 33 includes a main rod 331 and a plurality of support rods 332. The main rod 331 and the plurality of support rods 332 slide within the groove 321, and each support rod 332 is arranged alternately between two adjacent first comb teeth 320. Each second comb tooth 330 is respectively disposed on each support rod 332.

[0044] It should be noted that the main rod 331 slides within the groove 321. One end of each support rod 332 is respectively positioned on opposite sides of the main rod 331, while the other end of each support rod 332 extends outwards perpendicular to the axis of the main rod 331, away from the main rod 331. The spacing between each support rod 332 is consistent with the spacing between each first comb tooth 320. When each support rod 332 is staggered between two adjacent rows of first comb teeth 320, each support rod 332 can slide towards each row of first comb teeth 320 in a corresponding manner. Furthermore, each support rod 332 is provided with several second comb teeth 330, allowing each support rod 332 to drive each second comb tooth 330 to slide towards each first comb tooth 320 in a corresponding manner. This makes the spacing between each second comb tooth 330 and each first comb tooth 320 adjustable.

[0045] It should be noted that the sliding direction of the main rod 331 relative to the groove 321 is perpendicular to the direction of combing, while each support rod 332 is vertically arranged on both sides of the main rod 331, and there is a gap between each support rod 332, so that the gap between each support rod 332 is parallel to the direction of combing. In this way, during the combing process, the hair can pass between each row of first comb teeth 320 and each row of second comb teeth 330 to comb the hair.

[0046] like Figure 8 As shown, in one embodiment, the comb holder 32 is also provided with a through groove 322, which connects the inner side wall of the groove 321 and the outer side wall of the comb holder 32. The end of the main rod 331 that is away from each support rod 332 extends out from the through groove 322.

[0047] It should be noted that a through groove 322 is provided on one end of the comb base 32. The two ends of the through groove 322 are connected to the inner side wall of the groove 321 and the outer side wall of the comb base 32, respectively, and the opening direction of the through groove 322 is perpendicular to the combing direction. The main rod 331 slides in the groove 321, and the end of the main rod 331 away from each support rod 332 extends out from the through groove 322, so that the user can use the extended part of the main rod 331 to drive each second comb tooth 330 to move closer to or away from each first comb tooth 320.

[0048] like Figures 6 to 7 , Figure 9 As shown, in one embodiment, a sliding post 324 is provided on the comb seat 32, and the end of the sliding post 324 away from the comb seat 32 passes through the comb block 33, and the elastic member 34 is sleeved on the sliding post 324.

[0049] It should be noted that one end of the sliding column 324 is disposed on the comb holder 32, and the sliding column 324 is located on the end face of the comb holder 32 where the through groove 322 is formed. A stop block 333 is disposed on the main rod 331, and the stop block 333 is located on the end of the main rod 331 that extends relative to the through groove 322, and there is a gap between the stop block 333 and the end face of the comb holder 32. Further, the end of the sliding column 324 away from the comb holder 32 passes through the stop block 333, and the elastic member 34 is sleeved on the sliding column 324, so that both ends of the elastic member 34 abut against the comb holder 32 and the stop block 333 respectively. When the user pushes the main rod 331 to bring each second comb tooth 330 closer to each first comb tooth 320, the main rod 331 simultaneously drives the stop block 333 closer to the comb holder 32 to compress the elastic member 34. When the user releases the push rod 331, the elastic force of the elastic element 34 pushes the stop block 333 to drive the main rod 331 to slide, so that each second comb tooth 330 returns to its initial position away from each first comb tooth 320.

[0050] like Figures 1 to 3 , Figure 6 , Figures 10 to 11 As shown, in one embodiment, the adjustment component further includes a housing 30, on which a plurality of perforations 301 are provided, and each group of adjacent first comb teeth 320 and second comb teeth 330 pass through a perforation 301.

[0051] It should be noted that the comb holder 32 is mounted on the base 20. The outer casing 30 has an insert groove 302 on the side closest to the base 20. The outer casing 30 covers the base 20 so that the comb holder 32 extends into the insert groove 302, thereby clamping and fixing the comb holder 32 to the base 20. The comb holder 32 has a groove 321. When the outer casing 30 is close to the comb holder 32, the inner bottom wall of the insert groove 302 and the groove 321 together form a sliding cavity, and the comb block 33 slides in the sliding cavity. Furthermore, the outer shell 30 is provided with a plurality of perforations 301. The two ends of each perforation 301 are respectively connected to the inner bottom wall of the embedded groove 302 and the outer side wall of the outer shell 30. The perforations 301 are distributed in an equidistant array. When the outer shell 30 is placed on the base 20 to clamp the comb seat 32, each perforation 301 is connected to the groove 321. At the same time, a group of adjacent first comb teeth 320 and second comb teeth 330 pass through a perforation 301 and extend from the side of the outer shell 30 away from the base 20. Furthermore, the perforation 301 tends to be rectangular, and the length of the long side of the perforation 301 is greater than the distance between the first comb tooth 320 and the second comb tooth 330, so that when the outer shell 30 is placed on the base 20, the first comb tooth 320 and the second comb tooth 330 can respectively approach the two opposing inner sidewalls of the perforation 301, and the support rod 332 can drive the second comb tooth 330 to slide from one end of the perforation 301 to the other end to approach the first comb tooth 320.

[0052] like Figures 1 to 4 , Figure 6 , Figures 10 to 11 As shown, in one embodiment, the outer shell 30 is provided with a plurality of tooth sleeves, each tooth sleeve being equidistantly distributed, and each tooth sleeve being used to accommodate each first comb tooth 320 and each second comb tooth 330.

[0053] It should be noted that each tooth sleeve is located on the side of the outer casing 30 away from the base 20, and each tooth sleeve is located at both ends of the long side of the perforation 301, so that each tooth sleeve can accommodate the first comb tooth 320 and the second comb tooth 330 extending from the perforation 301.

[0054] like Figures 10 to 12 As shown, in one embodiment, the tooth sleeve has an inner groove, and the inner groove is connected to the through hole 301. Each inner groove is used to accommodate each first comb tooth 320 and each second comb tooth 330.

[0055] It should be noted that the tooth sleeve has an inner groove, which communicates with the perforation 301 when the tooth sleeve is placed on the outer shell 30. Two tooth sleeves are provided at each end of a perforation 301, ensuring that every two tooth sleeves communicate with a perforation 301. Furthermore, the size of the inner groove is adapted to the size of the portion of the first comb tooth 320 / second comb tooth 330 extending from the perforation 301, allowing the first comb tooth 320 / second comb tooth 330 to pass through the perforation 301 and extend into the inner groove, thus preventing the first comb tooth 320 / second comb tooth 330 from becoming misaligned during combing. Specifically, since each second comb tooth 330 can slide relative to the comb base 32, and the sliding direction is perpendicular to the combing direction, during combing, the hair exerts a force on the sides of each second comb tooth 330. Under long-term stress, the sides of each second comb tooth 330 are prone to misalignment, affecting the combing effect.

[0056] like Figures 10 to 12 As shown, in one embodiment, a guide bar 3030 is provided on the inner sidewall of the inner groove, and a guide groove 323 is provided on the outer sidewall of the first comb tooth 320. The guide bar 3030 and the guide groove 323 are slidably engaged.

[0057] It should be noted that one end of the inner groove is connected to the perforation 301, while the two sides of the inner groove perpendicular to the combing direction are connected to the external environment. Each tooth sleeve includes a first tooth sleeve 303 and a second tooth sleeve 304. The first tooth sleeve 303 is used to accommodate the first comb tooth 320, and the second tooth sleeve 304 is used to accommodate the second comb tooth 330. A guide strip 3030 is provided on the two opposing inner sidewalls of the inner groove on the first tooth sleeve 303. A guide groove 323 is provided on the two opposing outer sidewalls of the first comb tooth 320, and each guide groove 323 is perpendicular to the inner bottom wall of the groove 321. Thus, when the outer shell 30 moves each tooth sleeve to be placed on the base 20 so that each tooth sleeve accommodates the first comb tooth 320, the guide strip 3030 will slide in engagement with the guide groove 323, so that each first comb tooth 320 cannot slide relative to the tooth sleeve. Furthermore, since the second tooth sleeve 304 is connected to the external environment on both sides perpendicular to the combing direction, when the main rod 331 drives each support rod 332 to slide, each second comb tooth 330 can slide out from each inner groove perpendicular to the combing direction to approach each first comb tooth 320, thereby making the interval between each second comb tooth 330 and each first comb tooth 320 adjustable.

[0058] like Figures 1 to 4 , Figure 6 To the bone 7, Figures 10 to 12 As shown, in one embodiment, the outer shell 30 is further provided with a plurality of pillars 305, and each pillar 305 is equidistantly distributed along the circumference of the outer shell 30.

[0059] It should be noted that each post 305 is disposed on the surface of the outer shell 30 near each tooth sleeve, and each post 305 is equidistantly distributed along the circumference of the outer shell 30, so that each post 305 together surrounds each tooth sleeve. In this way, a protective ring-like structure is formed on the outer periphery of the outer shell 30 to prevent the tooth sleeves located in the center from being bent, broken or damaged during storage or carrying, thereby improving the combing effect of each first comb tooth 320 and each second comb tooth 330.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
