Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a comb with concave arcs on the upper and lower teeth and a spear-shaped spindle design at the front of the teeth for airflow guidance. Background Technology

[0002] Throughout its long history, the form and function of combs have continuously evolved. Early combs, such as those from the Neolithic period, had relatively simple shapes, mostly rectangular with flat teeth and ridges, primarily used to meet basic hair grooming needs. At that time, people's requirements for combs were limited to preventing hair from becoming tangled and hindering production activities. As time progressed, from the Shang Dynasty to the Warring States period, comb decorations gradually became more elaborate, craftsmanship became more refined, and the shape changed from rectangular to a winnowing basket shape. However, innovations in its combing function were relatively slow.

[0003] The drawbacks of traditional straight-line combs with simple structures are becoming increasingly apparent. Ordinary combs have difficulty combing through tangled or thick hair, often requiring multiple combing attempts, which is inefficient and can easily cause hair to slip out due to excessive pulling. Hairdressers also find it difficult to accurately control the thickness of hair sections during operation, resulting in large errors and seriously affecting the hairdressing effect and experience. Utility Model Content

[0004] The purpose of this invention is to provide a comb with concave arcs on the upper and lower surfaces of the teeth and a spear-shaped spindle design at the front end of the teeth. The guide teeth on the side wall of the comb handle are short and have spear-shaped tips, which can be inserted into the hair before combing to pre-separate knotted or tangled hair strands, reducing the resistance of subsequent combing and significantly improving combing efficiency. It also reduces damage to the hair caused by strong pulling. The concave arc groove in the middle of the outer surface of the comb teeth works in conjunction with the prismatic spearhead to optimize the grasping and separation effect of the hair, avoiding excessive pulling or inadequate combing in some areas, and improving the combing quality.

[0005] To achieve the above objectives, a comb with concave arc teeth and a spear-shaped spindle-shaped guide design at the front of the teeth is provided. The comb includes: a comb back; a comb handle is fixedly connected to both sides of the outer surface of the comb back; a positioning hole is provided on the front surface of the comb handle; guide teeth are provided on the sidewall of the comb handle; the guide teeth and the comb handle are provided with a plurality of comb teeth; a concave arc-shaped groove is provided in the middle of the outer surface of each comb tooth; and a prismatic spearhead is fixedly connected to the lower surface of each comb tooth. The fixed connection between the comb back and the comb handle ensures stable grip; the positioning holes facilitate functional expansion; the guide teeth, comb teeth, and special tooth shape design improve combing efficiency and accuracy; and the concave arc-shaped groove optimizes the hair-grabbing effect of the comb teeth.

[0006] According to the aforementioned comb with concave upper and lower teeth and a spear-shaped spindle-shaped guide design at the front of the teeth, the position of the prismatic spearhead is parallel to the position of the comb handle. The length of the guide teeth is shorter than that of the comb teeth, and the tips of the guide teeth are also spearhead-shaped. The parallel alignment of the prismatic spearhead with the comb handle ensures precise combing angles. The design of long and short teeth and the spearhead creates layered combing, enhancing the combing effect and smoothness.

[0007] According to the aforementioned comb with concave upper and lower teeth and a spear-shaped spindle-shaped guide design at the front of the teeth, the outer surface of the comb handle is provided with anti-slip texture, and the comb teeth array is distributed on the lower surface of the comb back. The anti-slip texture prevents the comb from slipping during use, and the comb teeth array distribution ensures full coverage of the hair, improving combing evenness and operational safety.

[0008] According to the aforementioned comb with concave upper and lower teeth and a spear-shaped spindle-shaped guide design at the tooth tip, the interior of the positioning hole is connected to the rear surface of the comb handle. The through-hole design facilitates connection with other accessories, meets diverse usage needs, and expands the comb's functionality and application scenarios.

[0009] The above-mentioned solution has the following beneficial effects:

[0010] This invention features a comb handle, positioning holes, guide teeth, comb teeth, concave arc-shaped grooves, and prismatic spearheads. The guide teeth on the sidewall of the comb handle are short and have spearhead-shaped tips, allowing them to be inserted into the hair before combing to pre-separate knotted or tangled strands, reducing resistance during subsequent combing and significantly improving combing efficiency. This also reduces damage to the hair caused by strong pulling. The concave arc-shaped groove in the center of the outer surface of the comb teeth works in conjunction with the prismatic spearheads to optimize the gripping and separation of hair, preventing excessive pulling or inadequate combing and improving overall combing quality.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-3 This utility model discloses a comb with concave upper and lower teeth and a spear-shaped spindle-shaped guide design. It includes a comb back 1, with comb handles 3 fixedly connected to both sides of the outer surface of the comb back 1. The comb back 1 provides support for the comb handles 3 through a stable connection structure, enabling the comb handles 3 to withstand external force during gripping and effectively transmit the force to the comb teeth 2 on the lower surface of the comb back 1, achieving stable combing operation. A positioning hole 4 is provided on the front surface of the comb handle 3, penetrating the structure of the front surface of the comb handle 3. The positioning hole 4 can cooperate with suitable positioning pins and connectors, allowing the comb to be precisely assembled and positioned with other auxiliary tools or storage devices, enhancing the comb's flexibility and storage convenience. Guide teeth 5 are provided on the side wall of the comb handle 3, attached to the side wall of the comb handle 3, forming a front guiding structure together with the comb handle 3. Before the comb teeth 2 contact the hair, the guide teeth 5 pre-separate the hair using their own shape, providing a guide for the comb teeth 2. Deep combing creates smooth conditions. The guide teeth 5 and comb handle 3 are equipped with several comb teeth 2. The comb teeth 2 and guide teeth 5 are arranged in an orderly manner with the comb handle 3 as the carrier, forming a hierarchical combing tooth group. Under the overall framework of the comb back 1, the hair styling process is achieved through the pre-combing of the guide teeth 5 and the fine combing of the comb teeth 2. Each comb tooth 2 has a concave arc groove 6 in the middle of its outer surface. The combination of the concave arc groove 6 and the outer surface of the comb tooth 2 changes the contact shape between the comb tooth 2 and the hair. It works in conjunction with the rhomboid spearhead 7 on the lower surface of the comb tooth 2 to form a unique contact surface during combing, optimizing the grasping and separation effect of the hair. The rhomboid spearhead 7 is fixedly connected to the lower surface of each comb tooth 2. The rhomboid spearhead 7 is firmly connected to the lower surface of the comb tooth 2. With its geometric shape, it cuts into the hair first during the combing process of the comb tooth 2, effectively reducing the resistance when the comb tooth 2 enters the hair as a whole and improving combing efficiency.

[0020] The prismatic spearhead 7 is positioned parallel to the comb handle 3. This parallel arrangement ensures that the prismatic spearhead 7 maintains the correct cutting angle when the user holds the comb handle 3 for combing, acting stably and efficiently on the hair and maintaining the smoothness of the combing process. The guide teeth 5 are shorter than the comb teeth 2, and their tips are also spearhead-shaped. The short length and spearhead design of the guide teeth 5 complement the longer comb teeth 2 in terms of height difference and function. During combing, the guide teeth 5 loosen the hair first, and the comb teeth 2 follow up to comb, together forming an efficient layered combing system. The outer surface of the comb handle 3 has anti-slip textures, which cover the outer surface of the comb handle 3 to increase the grip between the hand and the comb handle 3. The coefficient of friction, working in conjunction with components such as the comb back 1 and comb teeth 2, provides users with a stable grip when holding the comb handle 3, ensuring the accuracy and safety of combing actions. The comb teeth 2 are arrayed on the lower surface of the comb back 1, and are closely arranged in an array on the lower surface of the comb back 1. Under the rigid support of the comb back 1, a complete and uniform combing working surface is formed, which can fully cover the hair area and ensure the integrity and uniformity of the combing operation. The interior of the positioning hole 4 is connected to the rear surface of the comb handle 3. The structural design of the positioning hole 4, which runs through the front and rear surfaces of the comb handle 3, provides a through channel for various connecting components, enabling the comb to be stably connected with other functional accessories, expanding the functionality and applicability of the comb in different usage scenarios.

[0021] Working principle: First, the user holds the comb handle 3 by its non-slip texture on the outer surface. The stable connection between the comb back 1 and the handle 3 ensures the comb remains stable in the hand. The positioning hole 4 can be reserved for connecting auxiliary accessories. When the comb is brought close to the hair, the guide teeth 5 on the side wall of the handle 3, with their short length and spear-like tips, make initial contact with the hair, pre-separating knots or tangles, creating conditions for subsequent combing by the comb teeth 2. Pushing the comb, the array of comb teeth 2 on the lower surface of the comb back 1 penetrates deep into the hair. The sharp, prismatic tips 7 on the lower surface of the comb teeth 2 cut into the hair, reducing the overall... The comb resists the entry of hair; at the same time, the concave arc groove 6 on the outer surface of the comb teeth 2 cooperates with the prismatic spearhead 7 to optimize the gripping and separation effect on the hair. During the combing process, the parallel layout of the prismatic spearhead 7 and the comb handle 3 ensures that it always acts on the hair at the correct angle. The layered combing system formed by the guide teeth 5 and the comb teeth 2 continues to play a role. The guide teeth 5 loosens the hair, and the comb teeth 2 performs fine combing. If necessary, the comb can be assembled with other auxiliary tools or storage devices through the positioning hole 4 and the matching positioning pin and connector to expand the use scenarios of the comb or to facilitate convenient storage.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
