Description

Technical Field

[0001] This utility model relates to the field of hair dryer comb technology, and in particular to a hot and cold air comb. Background Technology

[0002] When styling hair with a traditional hairdryer, the comb typically blows hot air in a 360-degree direction to dry and heat the hair for styling. For safety reasons, the temperature of the hot air from the hairdryer cannot be too high, resulting in a slow styling process that requires prolonged heating, and the style doesn't last long due to the low temperature.

[0003] Currently, the above problems are generally solved by using hot and cold combs. For example, Chinese utility model application CN202220209811.2 discloses a hot and cold comb and its double-layer composite heat insulation structure. It heats the comb teeth with a heating component, which can heat the hair while straightening it and softening it. At the same time, it cools the comb teeth with a cooling component, which can cool and set the heated hair while straightening it. Another example is Chinese invention patent application CN202210997087.9, which discloses a heated comb head and a heated comb with cool air output. Its first comb tooth has the temperature required to soften the hair, so the user can soften and comb the hair without feeling the hot air, thereby setting the hair. Then, the second comb tooth is used to comb the hair. At this time, the air outlet on the second mounting bracket outputs cool natural air to cool the hot hair, thereby quickly cooling the hair while combing it. However, all of the aforementioned patents soften hair through heat conduction and employ rigid comb teeth to achieve good heat transfer. Heating the hair requires direct contact between the comb teeth and the hair, which can easily lead to localized high temperatures at the contact point, making it difficult to heat the entire section of hair evenly and affecting the styling effect. Furthermore, different hair types require different combs. For example, coarse, tangled hair is best suited for wide-tooth combs or wooden combs to reduce pulling and static electricity, while fine, soft hair is best suited for soft-bristled combs such as boar bristle combs or cushion combs. The former distributes scalp oil evenly, increasing shine, while the latter's soft cushion design reduces pulling on fine, soft hair. To achieve good heat conduction, the combing components of these patents are limited to rigid teeth, making them unsuitable for users with different hair types and impacting the user experience.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0005] The purpose of this utility model is to provide a hot and cold air comb that heats and shapes hair with hot air and then cools and sets the heated hair, thereby achieving quick styling and long-lasting hairstyle, effectively improving the styling effect, and can also be adapted to different hair types.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a hot and cold air comb, comprising:

[0008] A hair comb, wherein the outer surface of the hair comb is provided with at least one hair-curling plate and the interior of the hair comb is provided with at least two non-communicating cavities, and the hair comb is provided with a plurality of air outlet holes connected to the cavities.

[0009] The comb handle has one end connected to the comb head, and the comb handle is provided with one or more non-interconnected air ducts. Some of the air ducts are connected to some cavities to form a hot air channel. A heating component is provided in the hot air channel, and the air outlet of the hot air channel corresponds to a part of the hair curling plate.

[0010] A fan is used to drive air to form an airflow and allow some or all of the airflow to enter a hot air passage.

[0011] Furthermore, the comb handle includes an air guide tube, the fan is disposed at the end of the air guide tube away from the comb head, and at least two non-communicating air ducts are provided inside the air guide tube. Part of the air ducts are connected to a part of the cavity to form a hot air channel, and the remaining air ducts are connected to the remaining cavities to form a cold air channel. The heating component is disposed in the air duct corresponding to the hot air channel.

[0012] Furthermore, the comb handle includes an air guide tube, the fan is located at the end of the air guide tube away from the comb head, the heating component is located inside the air guide tube, and an air duct is provided inside the air guide tube, the air duct communicating with a portion of the cavity to form a hot air channel.

[0013] Furthermore, the comb handle also includes a housing, the air duct is sleeved inside the housing, and one end of the housing is connected to the comb head and the other end of the housing is provided with an air inlet mesh.

[0014] Furthermore, the comb handle is provided with a gear adjustment ring and a control board, and the heating component, fan, and gear adjustment ring are all electrically connected to the control board.

[0015] Furthermore, it also includes a power cord, which is electrically connected to the control board and one end of the power cord is clamped to the comb handle by a locking ring.

[0016] Furthermore, the comb includes a bristle base, one end of which is connected to the comb handle. The hair-curling plate is disposed on the outer surface of the bristle base. Additionally, multiple bristles are spaced apart on the outer surface of the bristle base, and the interior of the bristle base is divided by a partition to form at least two non-communicating cavities.

[0017] Furthermore, the comb holder is provided with a top cover at the end away from the comb handle.

[0018] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0019] This invention features a hot air channel. A fan drives air into the channel, which is then heated by a heating element to form an airflow. This airflow is then blown out through the air outlet, creating hot air that evenly heats the entire section of hair, softening and shaping it. This effectively improves the styling effect. Furthermore, the heat is transferred via hot air convection, allowing the invention to adapt to different hair types. Additionally, by placing at least one perming plate on the outer surface of the comb, with the hot air outlet corresponding to the perming plate, the blown hot air heats the perming plate. When needed, the high-temperature perming plate quickly softens and shapes the hair, which is then cooled and styled by the lower-temperature portion of the comb (excluding the perming plate). This achieves a rapid styling effect and allows the style to last longer.

Detailed Implementation

[0030] 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.

[0031] Example 1

[0032] Please refer to Figures 1 to 5 This embodiment provides a hot and cold air comb, comprising:

[0033] The comb 1 has at least one hair-curling plate 2 on its outer surface and at least two non-communicating cavities 3 inside. The comb 1 also has multiple air outlets 4 that communicate with the cavities 3.

[0034] The comb handle 5 is connected to the comb head 1 at one end. The comb handle 5 is provided with one or more non-interconnected air ducts 6. Part of the air ducts 6 are connected to part of the cavity 3 to form a hot air channel. A heating component 7 is provided in the hot air channel. The air outlet of the hot air channel corresponds to part of the hair perming plate 2. The air in the hot air channel is heated by the heating component 7 and blown out from the hot air channel and the air outlet 4 in sequence, which can heat the hair perming plate 2 located nearby.

[0035] The blower 8 drives air to form an airflow and allows part or all of the airflow to enter the hot air channel, so that at least a portion of the airflow is heated by the heating component 7 to form hot air. This hot air can be used to evenly heat the entire section of hair through thermal convection, softening and shaping it, effectively improving the styling effect. Moreover, the heat is transferred through hot air convection rather than through heat conduction, making the structure of the comb unrestricted. Both hard comb teeth and soft comb bristles are applicable in this embodiment, thus adapting to different hair types. In addition, the hot air is dispersed and heats the nearby perming plate 2 as it is blown out, causing the perming plate 2 to be heated and heated. The side of the comb 1 away from the hot air is not heated and remains cold. When needed, the hair is heated by the high-temperature part of the perming plate 2 to quickly soften and shape it, and then the heated hair is cooled and shaped by the low-temperature side of the comb 1, thus achieving a rapid styling effect. Furthermore, the hair retains its style for longer after being subjected to high temperature and rapid cooling.

[0036] Preferably, the perming plate 2 is made of a metal with good thermal conductivity, so that it can be heated to a high temperature by hot air. Furthermore, the perming plate 2 has multiple through holes, a hollow structure, or multiple perming plate 2 gaps woven into a mesh structure, so that some hot air can pass through the perming plate 2 and blow the hair. The perming plate 2 is fixed to the comb head 1 by embedding, gluing, snapping, or screwing. The comb head 1 is made of plastic with poor thermal conductivity, which can effectively prevent the heat of the hot air from being transferred to the side of the comb head 1 away from the air outlet of the hot air channel. The heating component 7 is a metal or ceramic heating element.

[0037] Preferably, the comb head 1 has a flat elliptical cross-section, forming two sides. There are two perming plates 2, which are respectively set on the two sides of the outer surface of the comb head 1. One perming plate 2 is opposite to the air outlet of the hot air channel and can be heated by hot air. The other perming plate 2 is far away from the air outlet of the hot air channel and is not heated by hot air, thus remaining in a cold state. The heated hair can be cooled and styled by the perming plate 2 on this side.

[0038] In this embodiment, the comb handle 5 includes an air guide duct 501, and the fan 8 is disposed at the end of the air guide duct 501 away from the comb head 1. Furthermore, at least two non-communicating air ducts 6 are provided inside the air guide duct 501. The air ducts 6 can be made by common technical means such as perforation, chiseling, or partitioning on the air guide duct 501, which will not be described in detail here. Part of the air ducts 6 are connected to part of the cavity 3 to form a hot air channel, and the remaining air ducts 6 are connected to the remaining cavities 3 to form a cold air channel. The heating component 7 is disposed in the air duct 6 corresponding to the hot air channel.

[0039] Preferably, please refer to Figure 3 , Figure 4 and Figure 5 There are two air ducts 6 and two cavities 3. The two air ducts 6 are connected to the two cavities 3 respectively to form two airflow channels that are not connected to each other. A heating component 7 is set in one airflow channel to form a hot air channel, and no heating component 7 is set in the other airflow channel to form a cold air channel. When the fan 8 is running, it drives the air entering the air guide duct 501 to be divided into two parts and enter the two airflow channels respectively. The air entering the hot air channel is heated and blown out from the corresponding air outlet 4 to form hot air. The air entering the cold air channel is blown out directly from the corresponding air outlet 4 to form cold air. It can heat and cool the corresponding hair curling plate 2 respectively.

[0040] It is understood that the number of air ducts 6, cavities 3, and heating components 7 can all be two or more. Each air duct 6 is connected to each cavity 3 to form multiple airflow channels that are not interconnected. In one part of the airflow channels, heating components 7 are set to form multiple hot air channels, while in another part of the airflow channels, heating components 7 are not set to form multiple cold air channels. Both can generate hot air and cold air and blow them out.

[0041] In this embodiment, the comb handle 5 further includes a housing 502, and the air guide pipe 501 is sleeved inside the housing 502. One end of the housing 502 is connected to the comb head 1, and the other end of the housing 502 is provided with an air inlet screen 503. When the fan 8 is running, outside air is drawn into the housing 502 through the air inlet screen 503 and compressed by the fan 8 to form an airflow, which is then sent into the air guide pipe 501.

[0042] Preferably, the outer shell 502 is composed of two shell pieces joined together, which effectively reduces the difficulty of production.

[0043] In this embodiment, the comb handle 5 is equipped with a gear adjustment ring 9 and a control board 10. The heating component 7, the fan 8, and the gear adjustment ring 9 are all electrically connected to the control board 10. The user can rotate the gear adjustment ring 9 as needed, and the control board 10 controls the start / stop and operating power of the heating component 7 and the fan 8 according to the signal received from the gear adjustment ring 9.

[0044] In this embodiment, a power cord 11 is also included. The power cord 11 is electrically connected to the control board 10, and one end of the power cord 11 is clamped to the comb handle 5 by a locking ring 12. When the other end of the power cord 11 is connected to an external power source, it can supply power to the control board 10.

[0045] In this embodiment, the comb 1 includes a comb base 101, one end of which is connected to the comb handle 5. The hair curling plate 2 is disposed on the outer surface of the comb base 101. Furthermore, multiple comb bristles 102 are distributed at intervals on the outer surface of the comb base 101, and the interior of the comb base 101 is divided by a partition 103 to form at least two non-communicating cavities 3.

[0046] The comb bristles 102 are made of a relatively soft material. When combing oily or fine hair, they can evenly distribute scalp oil to increase shine, reduce pulling on fine hair, reduce scalp irritation, and improve the user experience.

[0047] Optionally, the comb base 101, partition 103, and comb handle 5 are fixedly connected to each other by adhesive, screw, riveting, or welding; the comb base 101 and partition 103 are both made of plastic with poor thermal conductivity.

[0048] In this embodiment, the comb holder 101 is provided with a top cover 13 at the end away from the comb handle 5, which can restrict the hair curling plate 2's freedom in its length direction and is more aesthetically pleasing.

[0049] In this embodiment, the heating assembly 7 and the fan 8 are activated via the control board 10, and the speed adjustment ring 9 is adjusted to a suitable speed. The fan 8 rotates, drawing outside air into the housing 502 through the air inlet 503 and compressing it into airflow. This airflow is then sent into the air duct 501. Part of the airflow enters the hot air channel, and the other part enters the cold air channel. The air entering the hot air channel is heated and blown out through the corresponding air outlet 4, forming hot air. The air entering the cold air channel is blown out directly through the corresponding air outlet 4, forming cold air. The hot air heats the perming plate 2 on one side, while the cold air cools the perming plate 2 on the other side, creating a temperature difference between the two perming plates 2. Therefore, this embodiment can evenly heat and shape the hair with hot air, and cool and set the heated hair with cold air or a low-temperature perming plate 2. Furthermore, it can quickly heat and shape the hair with a high-temperature perming plate 2 as needed, thus achieving rapid styling with a long-lasting hairstyle, effectively improving the styling effect.

[0050] Example 2

[0051] Please refer to Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that:

[0052] In this embodiment, the comb handle 5 includes an air duct 501, the fan 8 is located at the end of the air duct 501 away from the comb head 1, the heating component 7 is located inside the air duct 501, and an air channel 6 is provided inside the air duct 501. The air channel 6 communicates with a portion of the cavity 3 to form a hot air channel. The air in the hot air channel is heated by the heating component 7 to form hot air, which evenly heats the entire section of hair, softening and shaping it, effectively improving the styling effect. As the hot air is blown out, it also dissipates and heats a portion of the nearby perming plates 2, causing that portion of the perming plates 2 to heat up. The other portion of the perming plates 2, which is away from the hot air, does not have hot air blowing out, thus remaining cold. Therefore, when needed, the hair is heated by the high-temperature portion of the perming plates 2 to quickly soften and shape it, and then cooled and styled by the low-temperature portion of the perming plates 2, thereby achieving a rapid styling effect. Moreover, the hair retains its style for a longer time after undergoing high temperature and rapid cooling.

[0053] Preferably, the air outlet end of the fan 8 is sealed and connected to the end of the air duct 501 away from the comb 1, and the fan 8 drives all the airflow into the air duct 501.
