[0002] Hair dryers are common household appliances. Most hair dryers direct the airflow directly at the user's hair to dry it. However, for users with thick, dense hair, the airflow cannot reach the roots. This results in the outer layer of hair being dried, while the inner layers close to the scalp remain wet. By the time the inner layers are dried, the outer strands have already been damaged by prolonged exposure to high temperatures. Furthermore, using a hair dryer requires holding the hairdryer in one hand and constantly moving the hair with the other to dry the inner layers faster, which is extremely inconvenient and can lead to messy, flat, and unsightly hair. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] See attached document Figures 1 to 9 This utility model provides a hair dryer accessory for hair care, designed to be used with a hair dryer.

[0037] The hair dryer accessory includes a main body 1 and a comb assembly 2. The main body 1 has an air cavity 10, an air inlet 111, and multiple air outlets 132. The air outlets 132 and the air inlet 111 are all connected to the air cavity 10. The comb assembly 2 includes a cylindrical body 21 rotatably mounted on the main body 1 and comb teeth 22 mounted on the cylindrical body 21. The cylindrical body 21 is located on one side of the air outlet 132 in the direction of airflow. The main body 1 is provided with multiple first air guides 131, each of which corresponds to an air outlet 132. The multiple first air guides 131 are arranged sequentially along a first direction. The multiple first air guides 131 are all used to guide the gas flowing through the air outlet 132 to flow along the outer wall of the cylindrical body 21.

[0038] This invention utilizes multiple air outlets 132 and multiple first air guides 131 to direct the airflow from each outlet 132 towards the outer wall of the cylinder 21, forming an adhering airflow with a consistent path, thus effectively increasing the airflow intensity reaching the outer wall of the cylinder 21. This allows the user to loosen the inner hair strands when combing with the comb teeth 22, and the airflow from the multiple outlets 132 can directly reach the inner hair strands or roots, effectively increasing the drying speed of the inner hair. This solves the problem of existing hair dryers failing to reach the inner hair and requiring the use of another hand to manipulate the hair. The hair dryer accessory of this invention allows for convenient one-handed operation, quickly drying both the inner and outer hair layers, effectively reducing the time the surface hair is exposed to high temperatures and minimizing hair damage. It also features comb teeth 22 for combing hair. When blow-drying, the comb teeth 22 reach deep into the hair roots, allowing the hot air to heat and style the roots, resulting in naturally lifted and uncluttered hair. This avoids the problem of messy, flat hair sticking to the scalp after blow-drying, creating a fuller and more layered overall style. Furthermore, the barrel 21 is rotatably mounted on the main body 1, allowing the user to rotate the barrel 21 to change the relative position between the comb teeth 22 and the main body 1. This helps the user find the optimal angle between the comb teeth 22 and the main body 1, enhancing the user experience.

[0039] Specifically, the first direction is the direction of gas flow.

[0040] The main body 1 includes a docking base 11 and an air guide bracket 13. The air guide bracket 13 is connected to the docking base 11 and forms an air cavity 10 with the docking base 11. The air inlet 111 is located on the docking base 11. The air guide bracket 13 is wave-shaped, with a first air guide section 131 located at the top of the air guide bracket 13. Multiple air outlets 132 are distributed on one side of the top of a corresponding wave on the air guide bracket 13. The multiple air outlets 132 are all located on the same side of each wave, making the height of the multiple air outlets 132 consistent, so that the air blowing from the multiple air outlets 132 is in the same direction, and the air blown from the multiple air outlets 132 is blown towards the outer wall of the barrel 21 to form a stronger airflow, which, together with the comb teeth 22, can dry hair faster.

[0041] The first air guide section 131 is arc-shaped, and the top tangent of the outer wall of the cylinder 21 and the top tangents of the multiple first air guide sections 131 are on the same plane. In this way, the gas flowing near the air outlet 132 of the cylinder 21 can be guided to the outer wall of the cylinder 21, and the air outlet 132 can be guided by the first air guide section 131 near the cylinder 21, which can reduce airflow separation at the air outlet 132. The remaining first air guide sections 131 are used to guide the gas blown out of their respective corresponding air outlets 132 to the outer wall of the first air guide section 131 in front, so that the air blown out of the multiple air outlets 132 flows along the tangential direction of the outer wall of the cylinder 21, reducing airflow separation, and working with the comb teeth 22 to help the user dry the inner layer of hair.

[0042] In one embodiment, the first air guide 131 and the air guide bracket 13 can be two separate components. Specifically, the first air guide 131 is an arc-shaped panel that is attached to the air guide bracket 13 using methods such as snap-fit, adhesive, or ultrasonic pressing. Alternatively, in other embodiments, the first air guide 131 can be integrally formed with the air guide bracket 13.

[0043] In one embodiment, the air guide bracket 13 is provided with a plurality of second air guide sections 133, which are located inside the air cavity 10. The plurality of second air guide sections 133 are spaced apart along the length direction of the cylinder 21. An air guide groove 134 is formed between every two adjacent second air guide sections 133 and the inner sidewall of the air guide bracket 13. The air guide groove 134 is used to guide the gas to the air outlet 132 for discharge. In this way, the air blown out by the hair dryer flows to the air guide groove 134 after passing through the air inlet 111 and the air cavity 10. The air is concentrated and the pressure is increased by the air guide groove 134 before being output from the air outlet 132, which can increase the air pressure at the air outlet 132 and increase the airflow speed at the air outlet 132, so as to speed up the efficiency of drying hair.

[0044] In this embodiment, the first end of a first air guide 131 is offset from the second end of an adjacent first air guide 131 so that the gas flowing from the air outlet 132 flows along the side wall of the first air guide 131, thereby better forming an attached airflow.

[0045] There are two first air guide sections 131 and three air outlets 132. The cross-section of the air guide bracket 13 is W-shaped. The air blown out of the three air outlets 132 follows the same path, which can ensure the strength of the airflow reaching the outer wall of the cylinder 21 and meet the user's needs. Of course, in other embodiments, the number of first air guide sections 131 can be three, four, five, etc., and the number of air outlets 132 can also be two, four, five, etc. Among them, the air outlets 132 can include multiple small round holes, with the openings of the small round holes facing the cylinder 21; or, the air outlets 132 can also be elongated through holes, with the openings of the through holes facing the cylinder 21; or, the air outlets 132 can also be composed of one or more notches, with the top and sides of the notches being through openings, which, together with the first air guide sections 131, can guide the air to flow along the direction of the cylinder 21.

[0046] In one embodiment, the main body 1 further includes a surrounding wall 12 and a first panel 14 and a second panel 15 respectively disposed on both sides of the surrounding wall 12. The surrounding wall 12 is hollow. The air guide bracket 13 is connected to the docking base 11 through the surrounding wall 12. The air cavity 10 is formed by the air guide bracket 13, the docking base 11 and the air guide bracket 13 surrounding it. The cylinder 21 is located between the first panel 14 and the second panel 15 and is located on one side of the surrounding wall 12. The cylinder 21 is rotatably connected to the first panel 14 and / or the second panel 15, that is, the cylinder 21 is located on one side of the air outlet 132.

[0047] Specifically, the enclosure 12 can be integrally formed with the docking base 11, or the enclosure 12 can be integrally formed with the air guide bracket 13. The first panel 14, the second panel 15, and the enclosure 12 are integrally formed; or, the first panel 14 and the second panel 15 are not integrally formed with the enclosure 12, and the first panel 14, the second panel 15 and the enclosure 12 are each a component, and the first panel 14 and the second panel 15 can be fixed to the enclosure 12 by means of clips, screws, adhesives, ultrasonic pressing, etc.; or, the first panel 14, the second panel 15, the docking base 11, and the air guide bracket 13 are integrally formed, etc.

[0048] In one embodiment, the barrel 21 includes a comb base 211 and a flexible substrate 212. The comb base 211 has a cavity 216 inside, and an opening 214 communicating with the cavity 216 is formed on the comb base 211. The flexible substrate 212 is disposed on the comb base 211 and located at the opening 214. The comb teeth 22 are disposed on the flexible substrate 212, which is made of a flexible material. In this way, when the user uses the comb teeth 22 to comb their hair, the cavity 216 can provide space to avoid the deformation of the flexible substrate 212, and the deformation of the flexible substrate 212 can bring a certain degree of elasticity to the comb teeth 22, making the comb teeth 22 feel softer and more elastic, thus improving the comfort of using the comb teeth 22.

[0049] Specifically, the flexible substrate 212 can be made of materials such as rubber, silicone, TPU (thermoplastic polyurethane), TPE (thermoplastic elastomer), or soft PVC (polyvinyl chloride). The comb base 211 and the flexible substrate 212 can be fixed together using a secondary injection molding process; alternatively, the flexible substrate 212 can also be fixed to the comb base 211 by means of bonding, ultrasonic welding, etc. Of course, in other embodiments, the cylinder 21 can also be integrally molded and lack elasticity.

[0050] In one embodiment, a rotation limiting structure 23 for increasing friction is provided between the barrel 21 and the main body 1. The rotation limiting structure 23 can keep the relative position between the barrel 21 and the main body 1 stationary when the user does not rotate the barrel 21, so that the user can comb the hair with the comb teeth 22.

[0051] The rotation limiting structure 23 includes a limiting ball head 232, a mounting base 231, and an elastic element 233. The mounting base 231 has a mounting cavity 2311 with one end being a limiting opening 2312. The elastic element 233 is placed inside the mounting cavity 2311. Part of the limiting ball head 232 is placed inside the mounting cavity 2311, with the portion of the limiting ball head 232 located outside the limiting opening 2312 for contact with the main body 1. Both ends of the elastic element 233 abut against the mounting base 231 and the limiting ball head 232, respectively. A column 213 is provided inside the cylinder 21, and the mounting base 231 is mounted on the column 213. The mounting base 231 is located on one side of the central axis of the cylinder 21. Multiple ribs 143 are provided on the main body 1, arranged along the central axis of the cylinder 21. A groove is formed between two adjacent ribs 143 for use with the limiting ball head 232. The elastic element 233 utilizes its restoring force to abut the limiting ball head 232 against the main body 1, increasing the friction between the cylinder 21 and the main body 1. This ensures that the relative position between the cylinder 21 and the main body 1 remains fixed when the user does not rotate the cylinder 21. Furthermore, when the user overcomes the friction between the limiting ball head 232 and the main body 1, the cylinder 21 can be rotated to adjust the angle between the comb teeth 22 and the main body 1 for user convenience. The locking groove also provides a tactile feedback when rotating the cylinder 21 and facilitates precise positioning of the relative position between the cylinder 21 and the main body 1.

[0052] Specifically, the elastic element 233 can be a compression spring, a torsion spring, or an S-shaped spring sheet, etc., and the limiting ball head 232 can be a ball or the end that contacts the main body 1 can be a spherical or arc-shaped surface.

[0053] Of course, in other embodiments, the limiting ball head 232 can also be in the shape of a cube, a frustum, etc. The rotation limiting structure 23 is a damping layer, wherein the damping layer is disposed at the rotation position of the cylinder 21 and the main body 1; or, the rotation limiting structure 23 can also be a protrusion, which is disposed on the cylinder 21 and makes contact with the main body 1 by compression, etc.

[0054] In one embodiment, shaft holes 217 are provided at both ends of the cylinder 21, and annular protrusions 142 are provided at the corresponding ends of the cylinder 21 on the main body 1. The annular protrusions 142 are placed in the shaft holes 217 to realize the rotatable connection between the cylinder 21 and the main body 1. Specifically, annular protrusions 142 are provided on both the first panel 14 and the second panel 15.

[0055] In this embodiment, the main body 1 is provided with a connector rod 141. The cavity 216 communicates with the shaft hole 217. The connector rod 141 is located on the annular protrusion 142 and is placed inside the cylinder 21, that is, the connector rod 141 is placed inside the cavity 216 and fits against the inner sidewall of the cylinder 21. This increases the contact area between the main body 1 and the cylinder 21, improving the reliability of the connection between the main body 1 and the cylinder 21 and the stability of rotation. Specifically, there are two connector rods 141, which are located on the annular protrusion 142 of the first panel 14 and the second panel 15, respectively.

[0056] In this embodiment, limiting portions 215 are provided on both sides of the inner wall of the cylinder 21 to limit the travel of the insertion rod 141, thereby limiting the rotation angle of the cylinder 21 and the comb teeth 22, preventing excessive rotation of the comb teeth 22, and preventing damage caused by contact between the comb teeth 22 and the air guide bracket 13. Specifically, the rotation of the cylinder 21 can be greater than 180°.

[0057] Of course, in other embodiments, the cylinder 21 can also be rotatably connected to the main body 1 via a shaft. For example, the shaft can pass through the cylinder 21, with both ends of the shaft placed inside holes in the main body 1, thus achieving a rotatable connection between the cylinder 21 and the main body 1. Alternatively, the main body 1 can have circular grooves at both ends corresponding to the cylinder 21, with both ends of the cylinder 21 placed within these grooves, also achieving a rotatable connection between the cylinder 21 and the main body 1. In this embodiment, the use of an annular protrusion 142 increases the contact area between the cylinder 21 and the main body 1, improving the reliability of the connection between the cylinder 21 and the main body 1, and enhancing the stability of the cylinder 21's rotation.

[0058] Furthermore, based on the aforementioned hair dryer accessory, this utility model also provides a device for hair care, including a hair dryer and the hair dryer accessory described in any of the above embodiments, wherein the hair dryer accessory is detachably connected to the hair dryer. Specifically, the hair dryer accessory is provided with a connector 112 that is detachably connected to the hair dryer, so that when the user is drying their hair, the hair dryer accessory can be attached to the hair dryer, so that the air blown by the hair dryer can reach the roots of the hair, thereby increasing the speed of drying the hair and preventing the hair from becoming messy.
