Description

Technical Field

[0001] This utility model relates to the field of personal care electrical appliances, and in particular to a high-speed hot air comb. Background Technology

[0002] Hot air combs, as a common personal care tool, integrate the functions of blow-drying and combing, allowing users to style their hair with hot air while combing, making them very popular in the market. When existing hot air combs are in operation, a motor drives a fan to rotate, drawing in external cold air through the air inlet on the handle. After flowing through the heating element, the air becomes hot air and is then blown out through the air outlets within the comb teeth assembly, acting on the hair.

[0003] However, traditional hot air brushes have a significant drawback: their airflow direction is fixed. The airflow exits from the vents in a single, fixed direction. This means that during styling, users need to frequently manually rotate or adjust the angle of the hot air brush to ensure the hot air is evenly distributed across the different sides of the hair. This operation is cumbersome and inconvenient, especially when creating hairstyles with volume and texture. The fixed airflow direction makes it difficult to achieve a circular heating effect around the hair strands, resulting in lower styling efficiency and less effective results. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed hot air comb that can automatically change the airflow direction, resulting in uniform and efficient heating and shaping.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-speed hot air comb, including a handle and a comb tooth assembly mounted on the handle. A first motor is provided inside the handle, which divides the internal space of the handle into an air inlet chamber and a heating chamber located on both sides. An air inlet hole corresponding to the position of the air inlet chamber is opened on the handle. A rotating air duct is provided inside the comb tooth assembly, and an air outlet hole corresponding to the position of the rotating air duct is opened on the comb tooth assembly. The first motor drives the airflow to enter from the air inlet hole and flow through the air inlet chamber, the heating chamber and the rotating air duct in sequence. A second motor is provided inside the handle, which drives the rotating air duct to rotate, so that the airflow is rotated and discharged from the air outlet hole.

[0006] By adopting the above technical solution, directional airflow and rotational output are achieved, which not only improves the uniformity of hot air distribution and avoids local overheating, but also enhances the efficiency of drying and styling hair. At the same time, the overall structure is compact and easy for users to hold and use.

[0007] A further feature of this invention is that the comb assembly includes a comb skeleton and a comb shell covering the comb skeleton. Comb bristles are fixedly disposed on the comb skeleton, and the comb shell has perforations corresponding to the positions of the comb bristles. The air outlet is located on the comb shell.

[0008] By adopting the above technical solution, the rotating hot air can be applied directly and evenly to the hair strands while combing, achieving simultaneous combing and heating styling, resulting in better styling effects.

[0009] A further feature of this invention is that a rotating roller, which is connected to the output shaft of the second motor, is provided inside the rotating air duct, and the rotating roller is fixedly connected to the comb tooth frame.

[0011] A further feature of this invention is that: a connector is fixedly connected to the output shaft of the second motor, and a toothed groove is provided circumferentially at one end of the connector away from the output shaft of the second motor; a retaining rib is provided on the roller corresponding to the position of the toothed groove, and the toothed groove engages with the retaining rib.

[0012] By adopting the above technical solution, a robust transmission connection is provided, ensuring rotational synchronization.

[0013] A further feature of this invention is that the tooth groove is provided with an arc surface, which allows the tooth groove and the retaining rib to engage disengageably.

[0014] By adopting the above technical solution, the transmission components are allowed to automatically disengage under overload or abnormal conditions, avoiding damage to the motor, improving the safety and durability of the equipment, and facilitating fault recovery for users.

[0015] A further feature of this invention is that a support member is provided inside the rotating air duct, the support member is engaged with the handle, and the rotating roller passes through the support member.

[0016] By adopting the above technical solution, it is ensured that the rotating roller and the output shaft of the second motor always rotate on the same axis, preventing vibration and noise caused by swaying when the rotating roller rotates at high speed, and ensuring the smoothness of operation; in addition, the inner wall of the support component regulates and guides part of the airflow, so that the airflow enters the rotating air duct more smoothly and more concentratedly, reducing airflow turbulence and pressure loss, thereby improving airflow efficiency.

[0017] A further feature of this invention is that the support member is detachably connected to the handle, and a limiting component is provided between the support member and the comb assembly. When the support member is detached from the handle, the support member drives the comb assembly away from the handle through the limiting component.

[0018] By adopting the above technical solution, the comb tooth assembly can be automatically brought out when the support is disassembled, which facilitates the replacement or cleaning and maintenance of the comb tooth assembly.

[0019] A further feature of this invention is that: a limiting ring protrudes from the inner wall of the support member; an installation portion is provided at the end of the rotating roller away from the second motor; the comb frame extends toward the rotating air duct and forms an extension portion; the extension portion abuts against the outer wall of the installation portion; the installation portion, the extension portion, and the rotating roller together form a limiting groove for accommodating the limiting ring; the limiting groove and the limiting ring are in a limiting fit and together constitute the limiting component.

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] A high-speed hot air comb, such as Figure 1-8As shown, the device includes a handle 1 and a comb assembly 2 mounted on the handle 1. A first motor 3, a centrifugal fan motor, is installed inside the handle 1 to guide airflow into the handle 1. The first motor 3 divides the internal space of the handle 1 into an air inlet chamber 101 and a heating chamber 102 located on both sides. A heating element 103, which can be a ceramic heating core, is installed inside the heating chamber 102. An air inlet hole 11 corresponding to the position of the air inlet chamber 101 is provided on the handle 1. A rotating air duct 20 is provided inside the comb assembly 2, and the comb assembly 2 has a corresponding air duct 20. The air outlet 21 corresponding to position 0 is driven by the first motor 3 to enter through the air inlet 11, flowing sequentially through the air inlet cavity 101, the heating cavity 102, and the rotating air duct 20. A second motor 4, a geared motor, is installed inside the handle 1. The second motor 4 drives the rotating air duct 20 to rotate, causing the airflow to rotate and exit through the air outlet 21. The air inlet 11 is located at the tail of the handle 1, and the comb assembly 2 and its air outlet 21 are located above the handle 1. The rotating air duct 20, heating cavity 102, second motor 4, first motor 3, and air inlet 101 are arranged sequentially from top to bottom. This structural design achieves directional airflow and rotational output, improving the uniformity of hot air distribution, preventing localized overheating, enhancing drying and styling efficiency, and providing a compact overall structure for easy gripping and use.

[0040] Preferably, the comb assembly 2 includes a comb frame 22 and a comb shell 23 covering the comb frame 22. Comb bristles 221 are fixedly disposed on the comb frame 22. The comb shell 23 has perforations 231 corresponding to the positions of the comb bristles 221. Air outlets 21 are located on the comb shell 23. The air outlets 21 and perforations 231 are spaced apart and arranged in an array. During rotation, the comb frame 22, comb shell 23, and comb bristles 221 rotate synchronously. Through this structural design, while the comb bristles 221 comb the hair, the rotating hot air can act directly and evenly on the hair strands, achieving simultaneous combing and heating styling, resulting in a better styling effect. The specific explanation is as follows: Compared with traditional static hot air combs, the rotating bristles 221 actively wrap around and guide the hair, while the rotating hot air blows evenly and continuously from all sides onto the wrapped hair bundle, simulating the technique of "twisting the hair bundle while heating it with a hairdryer". This can quickly and easily create a natural, full, and long-lasting curl or fluffy effect. Moreover, when the rotating bristles 221 encounter resistance, they can roll over the knots, reducing the pulling sensation and making the combing process smoother and gentler on the scalp. In addition, compared with traditional static hot air combs, the rotating hot air forms a dynamic, uniform heat field around the hair bundle, avoiding heat accumulation at a certain point, thereby effectively preventing hair damage caused by local overheating.

[0041] Preferably, the rotating air duct 20 is provided with a rotating roller 5 that is drively connected to the output shaft of the second motor 4, and the rotating roller 5 is fixedly connected to the comb tooth frame 22. By setting the rotating roller 5, while providing support for the comb tooth assembly 2, the power is directly transmitted from the second motor 4 to the comb tooth assembly 2, ensuring the stable rotation of the rotating air duct 20, reducing energy loss, and improving transmission efficiency and reliability.

[0042] Preferably, the output shaft of the second motor 4 is fixedly connected to a connector 6. The end of the connector 6 furthest from the output shaft of the second motor 4 has a circumferentially oriented toothed groove 61. The inner wall of the roller 5 has a retaining rib 51 corresponding to the position of the toothed groove 61, and the toothed groove 61 engages with the retaining rib 51. This structural design provides a robust transmission connection, ensuring rotational synchronization.

[0043] Preferably, the tooth groove 61 is provided with an arc surface 611, and the orthographic projection of the end face of the retaining rib 51 in contact with the tooth groove 61 falls into the orthographic projection area of ​​the arc surface 611, so that the tooth groove 61 and the retaining rib 51 can be disengaged from each other. The retaining rib 51 is made of a flexible material, such as soft rubber. Under normal operating torque, the second motor 4 drives the connecting member 6 to rotate. Due to the positive pressure between the arc surface 611 and the retaining rib 51, static friction is generated, which drives the rotating roller 5 and the comb assembly 2 to rotate synchronously. When the comb assembly 2 is stuck (such as hair tightly wrapped around it) and the rotating roller 5 cannot rotate, the second motor 4 continues to drive the connecting member 6 to rotate. The torque applied to the retaining rib 51 increases sharply. When the torque exceeds the maximum static friction torque between the arc surface 611 and the retaining rib 51, the connecting member 6 and the rotating roller 5 no longer rotate synchronously. The connecting member 6 "spins" or "slips" relative to the retaining rib 51, so that the retaining rib 51 disengages from the tooth groove 61. The above structural design allows the transmission components to automatically disengage under overload or abnormal conditions, preventing motor damage, improving the safety and durability of the equipment, and facilitating fault recovery for users.

[0044] Preferably, a support member 7 is provided inside the rotating air duct 20. The support member 7 is engaged with the handle 1, and the rotating roller 5 passes through the support member 7 and is spaced apart from the support member 7. By providing the support member 7, it is ensured that the rotating roller 5 and the output shaft of the second motor 4 always rotate on the same axis, preventing vibration and noise caused by swaying when the rotating roller 5 rotates at high speed, and ensuring stable operation. In addition, since the rotating roller 5 rotates relative to the support member 7, there is a gap between the support member 7 and the rotating roller 5. This gap space constitutes part of the airflow channel from the heating chamber 102 to the rotating air duct 20, and the inner wall of the support member 7 regulates and guides part of the airflow, so that the airflow enters the rotating air duct 20 more smoothly and in a more concentrated manner, reducing airflow turbulence and pressure loss, thereby improving airflow efficiency.

[0045] Preferably, the support member 7 is detachably connected to the handle 1, and a limiting component is provided between the support member 7 and the comb tooth assembly 2. When the support member 7 is detached from the handle 1, the support member 7, through the limiting component, drives the comb tooth assembly 2 away from the handle 1. This structural design allows the comb tooth assembly 2 to be automatically pulled out when the support member 7 is removed, facilitating the replacement or cleaning and maintenance of the comb tooth assembly 2.

[0046] Preferably, a limiting ring 81 protrudes from the inner wall of the support member 7. A mounting part 52 is provided at the end of the roller 5 away from the second motor 4. The diameter of the mounting part 52 is smaller than that of the roller 5. A threaded hole is provided on the mounting part 52. The comb frame 22 extends toward the rotating air duct 20 and forms an extension part 222. The extension part 222 abuts against the outer wall of the mounting part 52. The mounting part 52 and the extension part 222 are connected by bolts. The mounting part 52, the extension part 222, and the roller 5 together form a limiting groove 82 that accommodates the limiting ring 81. The limiting groove 82 and the limiting ring 81 are matched for limiting and together constitute the limiting component. When the support member 7 is disassembled from the handle 1, the limiting ring 81 abuts against the extension part 222 and drives the extension part 222, as well as the roller 5 fixedly connected to the extension part 222, to be disassembled simultaneously. Through the above structural design, the assembly and disassembly of the comb component 2 can be achieved with a simple structure, and the operation is simple, thus optimizing the user experience.

[0047] In another implementation, the bolts between the mounting part 52 and the extension part 222 are first removed. When the support member 7 is disassembled from the handle 1, the limiting ring 81 abuts against the extension part 222 and drives the extension part 222 to disassemble synchronously, while the rotating roller 5 remains connected to the connecting member 6. During assembly, the support member 7 is fitted into the rotating roller 5 until the limiting ring 81 abuts against the end face of the rotating roller 5 (the end face of the limiting groove 82), and the installation is indicated by tactile feedback. Through the above structural design, the assembly and disassembly of the comb assembly 2 are realized with a simple structure, and the operation is simple, thus optimizing the user experience.

[0048] Preferably, a connector 91 is provided between the support member 7 and the handle 1. The connector 91 and the handle 1 are rotatably connected. The support member 7 and the handle 1 are connected through the connector 91. The connector 91 is provided with a protrusion 911. The support member 7 is provided with a slot 71 for receiving the protrusion 911. Preferably, there are a plurality of slots 71 and protrusions 911, which are arranged circumferentially along the support member 7 and the connector 91 and are spaced apart. The slot 71 includes an inlet area 711 and a limiting area 712. The protrusion 911 is engaged with the limiting area 712. In the positioning area 712, a locking member 92 is movably connected to the connector 91. The locking member 92 has a locked state in which the protrusion 911 is locked in the slot 71, and an active state in which the protrusion 911 is moved away from the slot 71. In the locked state, the locking member 92 is engaged in the entry area 711, fixing the protrusion 911 of the connector 91 in the limiting area 712. In the active state, the locking member 92 is moved away from the entry area 711, and the protrusion 911 of the connector 91 can be disengaged from the entry area 711, allowing the support member 7 to disengage from the connector 6. Through the above structural design, a secure and convenient assembly and disassembly between the support member 7 and the handle 1 is achieved.

[0049] Preferably, the support member 7 has a locking hole 62 corresponding to the position of the slot 71. The locking hole 62 and the slot 71 are coaxially aligned. The locking member 92 includes a locking tongue 921 passing through the locking hole 62. The locking tongue 921 enters the locking hole 62 and the slot 71 and abuts against the protrusion 911. The locking tongue 921 is provided with a lever 93 for controlling its axial displacement. The lever 93 controls the locking tongue 921 to move closer to or away from the locking hole 62. A return spring 94 is provided at the end of the locking tongue 921 away from the locking hole 62. The return spring 94 causes the locking tongue 921 to tend to move closer to the locking hole 62. Through the above structural design, quick locking or releasing is achieved, allowing the support member 7 and the comb tooth assembly 2 to be quickly disassembled and assembled. This facilitates the replacement of different comb teeth (such as rib comb teeth, air cushion comb teeth, etc.) to adapt to different usage needs. The operation is simple and easy to replace, optimizing the user experience.
