Description

Technical Field

[0001] This utility model relates to the field of comb technology, and more specifically, to a hot air comb. Background Technology

[0002] People with long hair typically need to hold a hairdryer in one hand and a comb in the other while blow-drying their hair to achieve a straight style and quick drying. However, this process requires users to frequently switch gestures to adjust the hairdryer's airflow level while simultaneously combing, making the overall process rather cumbersome and inconvenient for one-handed operation, especially prone to causing fatigue during prolonged use.

[0003] To improve drying efficiency and simplify the process, a type of hot air comb integrating blow-drying and combing functions has emerged on the market. In these products, hot air circulates inside the comb teeth and is expelled through openings in the teeth, achieving simultaneous combing and drying. For example, CN 205624990 U discloses a smart hair dryer comb with the air outlet located at the end of the comb teeth, directly blowing hot air to the scalp area. However, in this design, the hot air is concentrated at the tip of the comb teeth, resulting in concentrated heat and scalp burning, causing discomfort for users. Furthermore, because the hot air fails to effectively reach the structural layer between the hair roots and strands, the overall drying efficiency is not significantly improved compared to traditional hair dryers, leaving room for further optimization. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, the embodiments of this utility model propose a hot air comb, in which the temperature-controlled air outlet section in the middle of the comb teeth delivers air evenly, accelerating the drying speed; the closed hemispherical structure at the heat-conducting diffusion end disperses heat, preventing scalp burns and improving convenience and comfort.

[0005] The technical solution adopted by this utility model is as follows: a hot air comb is provided, including a housing, a heating wire, and a fan. The housing has multiple comb teeth on one side and an air inlet on the other side. The fan is disposed inside the housing. Each comb tooth has a heating wire. Each comb tooth includes a heat-conducting diffusion end and a temperature-controlled air outlet section. The heat-conducting diffusion end is located at the head of the comb tooth and has a closed structure. The temperature-controlled air outlet section is located in the middle of the comb tooth and has multiple air outlets evenly distributed on its outer periphery. The airflow enters the housing through the air inlet, flows into the comb tooth after being pushed by the fan, is heated by the heating wire to form hot air, and is blown out through the air outlet.

[0006] With the above structure, by evenly opening air outlet holes in the temperature-controlled air outlet section in the middle of the comb teeth, hot air is blown out from the inside of the comb teeth to the hair roots and hair strands at multiple points, significantly improving the drying speed; the closed hemispherical structure of the heat-conducting diffusion end effectively releases heat and avoids direct burns to the scalp; the integrated hot air comb structure simplifies the operation steps, eliminating the need for users to manually adjust the airflow level of the hair dryer, improving the convenience and comfort of use.

[0007] According to one embodiment of the present invention, the heat-conducting diffusion end has a hemispherical structure, which evenly diffuses heat to the surrounding area through the hemispherical end, reducing the burning sensation of concentrated hot air, and can be used for scalp massage to improve the comfort of use.

[0008] According to one embodiment of the present invention, a humidity sensor is provided on one side of the housing to monitor the humidity of the hair in real time. It can be linked with the control circuit to automatically adjust the heating power to prevent excessive drying and protect the hair quality.

[0009] According to one embodiment of the present invention, a conductive sheet is provided inside the outer shell, and each heating wire is electrically connected to the conductive sheet. The reliable connection of the conductive sheet improves the electrical contact stability and simplifies the assembly process of the component.

[0010] According to one embodiment of the present invention, the conductive sheet includes a first conductive ring and a second conductive ring arranged in inner and outer rings, and the two ends of the heating wire are electrically connected to the first conductive ring and the second conductive ring respectively, so that the heating wire is subjected to more uniform force and the heating is more stable.

[0011] According to one embodiment of the present invention, an inner shell is provided inside the housing, and the fan is fixedly installed on the inner shell. By supporting and positioning the fan through the inner shell, the operating vibration and noise are reduced, thereby improving the product's service life and user experience.

[0012] According to one embodiment of the present invention, the tail of the comb teeth is provided with a connecting air guide section, which is used to efficiently guide the airflow output by the fan into the comb teeth and deliver it to the temperature-controlled air outlet section, thereby achieving a seamless transition of the airflow channel and reducing wind resistance.

[0013] According to one embodiment of the present invention, the heat-conducting diffusion end, the temperature-controlled air outlet section, and the connecting air guide section are integrally molded structures, which simplifies mold manufacturing and injection molding processes and enhances the overall strength and sealing of the comb teeth.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0035] like Figure 1-9 As shown, this embodiment discloses a hot air comb, including a housing, a heating wire 5, and a fan 8. The housing has multiple comb teeth 3 on one side and an air inlet 1a on the other side. The fan 8 is disposed inside the housing. Each comb tooth 3 is provided with a heating wire 5. The comb tooth 3 includes a heat-conducting diffusion end 31 and a temperature-controlled air outlet section 32. The heat-conducting diffusion end 31 is located at the head of the comb tooth 3 and has a closed structure. The temperature-controlled air outlet section 32 is located in the middle of the comb tooth 3, and multiple air outlets 32a are evenly opened on its outer periphery. The airflow enters the housing through the air inlet 1a, is pushed by the fan 8 and flows into the comb tooth 3. It is heated by the heating wire 5 to form hot air, which is then blown out through the air outlets 32a.

[0036] Furthermore, combined Figure 3 As shown, the housing includes a first half-shell 1 and a second half-shell 2, which are connected by a mating joint to form a sealed cavity for accommodating and protecting internal structural components, such as a circuit board 9 and a battery 10 installed in this closed structure. The rear side of the housing has multiple air inlets 1a for introducing external air, and the front side of the housing has multiple comb teeth 3, each comb tooth 3 being independently arranged for contacting the hair and conducting hot air.

[0037] Furthermore, an inner shell 7 is provided inside the housing, and a fan 8 is fixedly mounted on the inner shell 7. The air inlet end of the fan 8 faces the air inlet hole 1a, and the air outlet end communicates with the interior of the comb teeth 3. The inner shell 7 serves to support and position the fan 8, effectively reducing the vibration and noise generated during the operation of the fan 8, improving the working stability of the fan 8, the overall product lifespan, and the user experience. The fan 8 is used to draw in air from outside the housing and deliver the air into the interior of the comb teeth 3 at a certain speed, forming a directional high-speed airflow.

[0038] Furthermore, combining Figure 4As shown, the comb teeth 3 have a hollow structure with an internal cavity containing a heating wire 5, which is fixed to the conductive sheet 6 by welding. Each comb tooth 3, from front to back, includes a heat-conducting diffusion end 31, a temperature-controlled air outlet section 32, and a connecting air guide section 33. The three sections are integrally formed, resulting in high overall structural strength and good sealing. The heat-conducting diffusion end 31 is located at the front end of the comb tooth 3 and has a hemispherical closed structure. This structure can evenly diffuse heat to the surrounding area, effectively releasing concentrated heat and preventing scalp burns. It also has a scalp massage effect, improving user comfort. The temperature-controlled air outlet section 32 is located in the middle of the comb tooth 3, and its outer periphery is evenly provided with multiple air outlet holes 32a. These holes are used to evenly spray the heated airflow as hot air, directly acting on the hair roots and strands, achieving simultaneous combing and drying. The connecting air guide section 33 is located at the tail of the comb tooth 3 and is connected to the internal air duct of the housing. It is used to guide the airflow generated by the fan 8 into the interior of the comb tooth 3 and deliver it to the temperature-controlled air outlet section 32, so as to achieve seamless connection of the airflow channel, reduce wind resistance, and improve the airflow efficiency.

[0039] Furthermore, a contact plane 31a is provided at the end of the heat-conducting diffusion end 31 to increase the contact area of ​​the heat-conducting diffusion end 31 and reduce the pressure.

[0040] Furthermore, combined Figure 4 As shown, in this embodiment, the outer diameter of the temperature-controlled air outlet section 32 gradually increases along the direction from the heat-conducting diffusion end 31 to the connecting air guide section 33, forming a gradually expanding structure. This causes the airflow velocity to gradually increase from front to back, which helps to improve the uniformity of hot air output, prevent single-point overheating, and enhance the temperature control performance and air outlet stability of the comb teeth 3. The comb teeth 3 can be made of materials with good heat resistance, such as nylon, heat-resistant plastic, metal, or wood, to ensure structural stability under continuous hot air action.

[0041] Furthermore, combining Figure 9 As shown, a conductive sheet 6 is provided inside the outer casing, and each heating wire 5 is electrically connected to the conductive sheet 6. The heating wire 5 is installed on the conductive sheet 6 by welding, and the conductive sheet 6 is then fixed to the inner wall of the casing by screws. The conductive sheet 6 consists of a first conductive ring 61 and a second conductive ring 62, arranged in a ring structure on the inner and outer sides respectively. The two ends of the heating wire 5 are the first end 51 and the second end 52, respectively. The first end 51 is fixedly connected to the first conductive ring 61, and the second end 52 is fixedly connected to the second conductive ring 62, thereby realizing the positive and negative polarity distribution of the electrical path. The above connection improves the installation strength and electrical contact stability of the heating wire 5, and also facilitates modular assembly and maintenance.

[0042] Furthermore, the hot air comb is also equipped with a humidity sensor 4, which is located on the same side as the comb teeth 3. The humidity sensor 4 is preferably positioned close to the comb teeth 3, enabling it to capture hair humidity signals in real time during the blow-drying process. In this embodiment, multiple comb teeth 3 are provided, and the humidity sensor 4 is located in the middle of these teeth. The humidity signal is transmitted to the processor in the circuit board 9 via wires. The processor dynamically determines the current dryness of the hair based on the collected data and generates control commands to adjust the working state of the fan 8. When high hair humidity is detected, the processor controls the fan 8 to run at high speed to output a large volume of hot air; when low humidity is detected, the fan speed is reduced, thereby decreasing the airflow and achieving automatic matching and adjustment between airflow and hair humidity.

[0043] In this embodiment, the hot air comb works as follows:

[0044] When the user holds the hot air comb and turns on the power switch, the circuit board 9 is powered on, activating the heating wire 5 and the fan 8. After the fan 8 starts, external air is drawn into the housing through the air inlet 1a. The resulting airflow is evenly distributed to the connecting air guide section 33 of each comb tooth 3 by the guiding effect of the inner shell 7. When the air flows through the cavity of the comb tooth 3, it comes into full contact with the electrically heated heating wire 5, rapidly heating up to form a hot airflow.

[0045] As the hot air flows along the temperature-controlled air outlet section 32, its velocity gradually increases due to the gradually narrowing inner radius of the structure, eventually radiating out from the air outlet 32a. At this time, the user places the comb teeth 3 close to the head, and the contact plane 31a of the heat-conducting diffusion end 31 gently contacts the scalp, transferring some heat to the hair roots while combing the hair; while the hot air ejected from the temperature-controlled air outlet section 32 acts directly on the hair strands, achieving rapid hair drying.
