Abstract
Description
Technical Field
[0001] This utility model relates to the field of hair styling tools, specifically a hot air comb with anti-scalding function and multiple interchangeable comb heads. Background Technology
[0002] Traditional hot air combs typically feature a fixed comb head design, offering limited functionality and failing to meet the diverse needs of different hairstyles, such as straightening or curling. Furthermore, direct hot air blowing onto the hair can easily cause burns to the scalp or damage to the hair due to excessive temperature, and the unreasonable arrangement of the air outlet and comb teeth results in uneven heat distribution.
[0003] A heat-resistant straightening comb disclosed in Chinese Publication No. CN220987916U attempts to improve its heat-resistant performance by adding a heat-insulating structure or adjusting the position of the air outlet. However, its heat-resistant effect relies on a single heat-insulating component and does not form a systematic heat control solution or achieve effective heat source isolation, resulting in limited heat-resistant performance. Furthermore, the fixed comb head limits its functionality, and replacing the comb head requires tools, making the operation cumbersome. Additionally, its air outlet is arranged vertically with the comb teeth, resulting in poor airflow guidance and a tendency for localized high-temperature accumulation during styling, failing to balance styling efficiency and safety. Therefore, there is an urgent need for a new type of hot air comb that combines a highly efficient heat-resistant structure, a replaceable comb head design, and scientific airflow guidance. Utility Model Content
[0004] This utility model overcomes the shortcomings of the above-mentioned technology and adopts the following technical solution:
[0005] A heat-resistant hot air comb includes a handle 1 and an air outlet 2 connected to the handle. The air outlet 2 is connected to a heat-resistant comb head via a snap-fit assembly 3.
[0006] Preferably, the anti-scalding comb includes a three-dimensional circular brush comb 41, with a handle 411 located at the middle of the end away from the air outlet 2.
[0007] Preferably, the anti-scalding comb includes a single-sided brush comb 42, which has a flow guide baffle 421 inside. The flow guide baffle 421 divides the inner cavity of the single-sided brush comb 42 into a lower flow guide cavity 422 and an upper isolation cavity 423.
[0008] Preferably, the main body of the handle 411 is a long elliptical cylinder structure, and has an asymmetrical curved surface 411a in the left and right directions of its long axis, with the two ends of the long axis extending to form reverse warped portions 411b.
[0009] Preferably, the sidewall of the handle 411 is uniformly distributed with longitudinally extending anti-slip ridges 411c.
[0010] Preferably, the upper part of the handle 411 is provided with a handle head 411d, the size of which is larger than the lower body of the handle in all circumferential directions, so as to increase the contact area between the hand and the handle 411.
[0011] Preferably, the three-dimensional ring brush head 41 is provided with first comb teeth 412 extending vertically from the outer surface and first strip-shaped air outlets 413 in the circumferential direction; the first comb teeth 412 are arranged in multiple rows in a staggered ring, and the first strip-shaped air outlets 413 and the first comb teeth 412 are arranged alternately.
[0012] Preferably, the baffle 421 is a long, arc-shaped plate that extends downwards from the top of the air inlet 424 of the single-sided brush head 42 to the tail of the brush head, and the arc surface of the baffle 421 protrudes towards the isolation cavity 423 to form an airflow guiding surface.
[0013] Preferably, the upper part of the single-sided brush head 42 is provided with a housing 425 for easy gripping, and the lower part is a working surface 426 that is recessed upwards; the working surface 426 is provided with second comb teeth 427 and a second strip-shaped air outlet 428 extending along its length direction, the extension direction of the second strip-shaped air outlet 428 intersecting the inclined direction of the guide baffle 421; the arc-shaped contour formed by the bottom of all the second comb teeth 427 is consistent with the curvature of the working surface 426; the upper part of the working surface 426 is provided with a heat insulation baffle 429, and the heat insulation baffle 429 is provided with strip-shaped holes that are aligned with the position of the second strip-shaped air outlet 428.
[0014] Preferably, the snap-fit assembly 3 includes:
[0015] The annular base 31 located at the end of the air outlet duct 2 has a radially protruding wedge-shaped locking block 32 on its inner wall;
[0016] The retaining ring 33 located at the connection end of the anti-scalding comb has an L-shaped locking groove 34 on its outer edge that matches the wedge-shaped retaining block 32;
[0017] The L-shaped locking groove 34 is provided with a limiting boss 35 with an arc surface.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. Active anti-scalding design of the 3D circular brush comb: The handle is located in the middle of the far end of the comb head. Its long elliptical cylindrical design increases the grip distance, keeping fingers away from the high-temperature area; the asymmetrical curved surfaces and reverse curvature on both sides of the long axis conform to the natural grip posture of the fingers, improving rotation comfort and reducing operation fatigue; the circumferential dimension of the handle head is larger than that of the main body, increasing the contact area of the hand, and combined with the anti-slip ridges, it enhances the stability of operation on wet hair and avoids slipping; the first strip-shaped air outlet is alternately distributed with the long comb teeth, and the hot air is evenly diffused from multiple directions. The gaps formed by the staggered layout of the comb teeth accelerate the airflow circulation and avoid local heat accumulation.
[0020] 2. Single-sided brush comb with multiple anti-scalding design: The inclined arc-shaped baffle concentrates the hot air into the baffle chamber. The isolation chamber reduces the transfer of heat to the upper part of the comb through physical separation, preventing the upper shell, which is easy to hold, from overheating. The heat insulation baffle at the bottom of the baffle chamber further prevents the high-temperature airflow from directly contacting the root of the comb teeth. Its strip-shaped holes are aligned with the second strip-shaped air outlet to ensure that the hot air is blown out evenly in a diffused form, reducing the heat intensity per unit area and preventing burns to the scalp.
[0021] 3. Refined adaptation of the single-sided comb's arc-shaped structure: The lower part of the comb adopts an upwardly concave arc-shaped working surface, which matches the natural curvature of the human head, ensuring that the pressure is evenly distributed when the comb teeth are in contact with the scalp, reducing pulling damage; Continuous arc-shaped arrangement of short comb teeth: The bottom of the comb teeth forms a smooth contour along the curvature of the arc-shaped working surface, enhancing the smoothness of combing, while avoiding hair-catching problems caused by inconsistent comb tooth lengths.
[0022] 4. Quick switching between multi-functional comb heads: The L-shaped locking groove and limiting protrusion design of the buckle component enable the "push and twist" operation to switch between the two comb heads in an instant, meeting the needs of instant switching between straight hair and curly hair.

[0025] Figure 3 This is a cross-sectional view of the single-sided brush comb of this utility model;
[0026] Figure 4 This is an exploded view of the single-sided brush comb of this utility model; Detailed Implementation
[0027] Example 1: Use of a 3D circular brush comb
[0028] Assembly process: such as Figure 1 and 2 As shown, align the retaining ring 33 at the connecting end of the three-dimensional ring brush comb 41 with the annular base 31 at the end of the air outlet duct 2, and push it axially so that the wedge-shaped retaining block 32 enters the vertical section of the L-shaped locking groove 34. Then rotate the comb head clockwise by 15° until the wedge-shaped retaining block slides along the horizontal section of the locking groove to the arc surface of the limiting boss 35 and locks, thus completing the installation of the three-dimensional ring brush comb.
[0029] Operation process: When using the product, the user's fingers naturally wrap around the handle head 411d. Due to the anti-slip ridges 411c on the side wall of the handle, even if the hands are wet and slippery due to hairspray residue, clear tactile feedback can be obtained, achieving a stable grip. When rotating the handle, the reverse curved part 411b guides the palm to apply force in the natural direction of force, causing the comb head to rotate flexibly. After the hot air is turned on, the first strip-shaped air outlet 413 cooperates with the staggered first comb teeth 412, and hot air is evenly sprayed out from the gaps between the comb teeth, circling and heating the hair, thereby achieving uniform heating and styling of the curls.
[0030] Example 2: Use of a single-sided brush head
[0031] Assembly process: Referring to the assembly method of the three-dimensional ring brush comb, the retaining ring 33 at the connecting end of the single-sided brush comb 42 is connected and fixed to the annular base 31 at the end of the air outlet 2 through the buckle assembly 3.
[0032] Operation process: such as Figure 3 , 4 As shown, when using the single-sided brush head 42, the hot air introduced by the air outlet 2 is directed at an acute angle to the guide cavity 422 via the guide baffle 421. Because the curved surface of the guide baffle bulges towards the isolation cavity 423, the hot air forms a spiral acceleration effect within the guide cavity. The isolation cavity 423 forms an air insulation layer, which, combined with the heat-insulating material of the upper grip shell 425, makes the surface temperature of the shell lower than that of the guide cavity, preventing burns when holding. After the hot air passes through the strip-shaped holes of the heat-insulating baffle 429 and is precisely aligned with the second strip-shaped blow-drying nozzle 428, it is sprayed out at an angle, reducing the heat intensity per unit area. When the user combs their hair, because the radius of curvature of the arc-shaped contour of the working surface 426 matches the side curve of the human head, and the bottom of the second comb teeth 427 is arranged along the curvature of the working surface to form a continuous arc, the contact pressure between the comb teeth and the scalp is evenly distributed, effectively reducing hair pulling damage and achieving smooth combing and styling of straight hair.
[0033] Example 3: Quick replacement of comb hair
[0034] like Figure 1 As shown, when a user needs to change from the three-dimensional circular brush comb head 41 to the single-sided brush comb head 42, or vice versa, they simply need to rotate the currently used comb head counterclockwise to disengage the wedge-shaped locking block 32 from the limiting boss 35 and rotate it to the opening of the L-shaped locking groove, and then remove it from the air outlet 2. Then, align the retaining ring 33 of the other comb head connection end with the annular base 31 at the end of the air outlet 2, align the wedge-shaped locking block 32 with the opening of the L-shaped locking groove 34, and follow the steps of axial push-in and clockwise rotation to make the wedge-shaped locking block 32 slide past the limiting boss 35 and complete the installation. The entire replacement process is simple, quick, and takes very little time, meeting the user's need to quickly switch between different hairstyles.
[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
