It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] See Figures 1 to 3 One embodiment of this application provides a hair dryer 100, which can dry hair or other items. The following description focuses on the hair drying function of the hair dryer 100. In this application, the hair dryer 100 includes a housing 10 and a blower component 20.

[0033] Specifically, the outer casing 10 has multiple independent air ducts 11 inside, and each air duct 11 has an air inlet 12 and an air outlet 13 at both ends. Each air duct 11 has a blower 20 inside, which, when in operation, allows airflow from the external environment to enter the air duct 11 through the air inlet 12 and exit through the corresponding air outlet 13. The hair dryer 100 has an air outlet channel 30 at each air outlet 13 corresponding to each air duct 11, and the air outlet directions of different air outlet channels 30 can be different.

[0034] For the hair dryer 100 of this application, the outer shell 10 has multiple independent air ducts 11 inside. Each air duct 11 is independently equipped with an air inlet 12, an air outlet 13, and a blower 20. The airflow can circulate independently within its respective air duct 11, effectively ensuring the stability of the wind speed and wind pressure in each direction and improving the overall blowing efficiency. In addition, the air outlet direction of the air outlet channel 30 formed by the multiple air ducts 11 is different, so that the user does not need to frequently adjust the position of the hair dryer 100 to achieve multi-area airflow coverage, so that the airflow distribution is more uniform and the range is wider, thereby effectively covering different areas of the object to be dried and improving the user experience.

[0035] In some embodiments of this application, the outer casing 10 includes a grip area 101 and a functional area 102. The air duct 11, air inlet 12, and air outlet 13 are all located in the functional area 102 of the outer casing 10. The grip area 101 of the outer casing 10 can form a handle-like structure for the user to hold the hair dryer 100.

[0036] The grip area 101 of the outer casing 10 has a handle-like structure, adapting to the user's hand-holding habits and enabling handheld use of the hair dryer 100. Users can operate the hair dryer 100 by holding the grip area 101 of the outer casing 10, adjusting the airflow angle to match the different directions of the air outlet channels 30, further enhancing the flexibility of multi-area airflow coverage. Furthermore, the air ducts 11, air inlets 12, and air outlets 13 are all located in the functional area 102 of the outer casing 10, reducing the probability of hand obstruction of airflow and ensuring stable external airflow into each independent air duct 11, thus ensuring the working efficiency of the blower component 20.

[0037] like Figure 3 As shown in this application, the interior of the outer casing 10 is provided with a plurality of independent air ducts 11, and the outer casing 10 has an air inlet 12 and an air outlet 13 respectively formed at both ends of each air duct 11.

[0038] In some examples, a partition can be installed inside the outer casing 10, dividing the internal space of the outer casing 10 into multiple independent cavities, each of which can form an air duct 11. In some examples, multiple independent tubular structures can be fixed inside the outer casing 10, with the two ends of the tubular structures corresponding to the air inlet 12 and air outlet 13 of the outer casing 10, respectively. The internal space of the tubular structures forms the air duct 11, and the tubular structures can be fixed to the inner wall of the outer casing 10 by means of clips, screws, or adhesives. In some examples, the outer casing 10 can be manufactured by a one-piece molding process such as injection molding, so that the inner surface of the outer casing 10 forms ribs or protrusions extending along the airflow direction. These ribs cooperate with each other to divide the interior of the outer casing 10 into multiple independent elongated spaces to form multiple independent air ducts 11.

[0039] Multiple independent air ducts 11 are set inside the outer casing 10. The airflow of each air duct 11 flows independently from the air inlet 12 to the air outlet 13, which can prevent the airflow disturbance of one air duct 11 from affecting other air ducts 11, ensuring the stability of wind speed and wind pressure of each air duct 11, and improving the overall blowing efficiency of the hair dryer 100.

[0040] In some examples, the air inlet 12 is a circular hole structure. Multiple air inlets 12 are provided at the end of each air duct 11, and the multiple air inlets 12 are arranged at intervals on the outer casing 10.

[0041] The circular air inlet 12 has an arc-shaped edge, which reduces the resistance of airflow as it enters, thereby reducing turbulence and allowing the airflow to enter the air duct 11 more smoothly. This improves air intake efficiency and reduces intake noise. Multiple spaced air inlets 12 can disperse the air intake points, avoiding local airflow congestion that occurs with single-hole air intake. This allows airflow to flow evenly into the air duct 11 from multiple directions, reducing air pressure fluctuations at the inlet of the air duct 11 and ensuring the stability of the airflow drawn into the blower 20, thus improving the consistency of the outlet air pressure.

[0042] In some examples, such as Figure 4 As shown, the outer casing 10 has multiple air outlets 13 at the end of the air duct 11, and the outline of the air outlets 13 is an arc-shaped strip. The multiple air outlets 13 are arranged at intervals and can be enclosed to form a circular structure.

[0043] The arc-shaped, elongated air outlet 13 has a certain curvature, which guides the airflow to diffuse along the arc direction, making the air outlet 13 cover a larger angle. Furthermore, multiple spaced arc-shaped holes can form a circular structure, achieving all-around airflow coverage and preventing localized airflow concentration or leakage. This is especially suitable for covering different areas of the head, such as the top and sides, when drying hair, reducing the frequency of manual adjustment of the hair dryer 100 position, improving drying efficiency and user experience.

[0044] In this application, each air duct 11 is provided with a blower 20. When the blower 20 is in operation, airflow from the external environment can enter the air duct 11 through the air inlet 12 and be output through the corresponding air outlet 13.

[0045] In some examples, the blower 20 can be a fan. The fan can be a fan structure with blades, or it can be a piezoelectric fan or a magnetic levitation fan.

[0046] Among them, the piezoelectric fan utilizes the inverse piezoelectric effect of piezoelectric materials to drive airflow through high-frequency vibration. The piezoelectric fan has no rotating parts inside, and its overall size and weight are small and light, making it suitable for narrow air ducts 11, which is conducive to the overall miniaturization and lightweight design of the hair dryer 100.

[0047] The magnetic levitation fan uses magnetic levitation technology to levitate and rotate the impeller, driving airflow through electromagnetic force. This magnetic levitation fan operates smoothly with extremely low vibration and noise, effectively reducing the energy consumption of the hair dryer and facilitating its quiet design.

[0048] In some examples, the blower component 20 can be a blower, an air pump, a jet device, etc. A blower compresses gas through impeller rotation or volume change to generate a high-pressure airflow, suitable for scenarios where the hair dryer 100 requires concentrated airflow, enhancing localized drying efficiency. An air pump, through the relative motion of a moving and stationary vortex disc, gradually compresses and discharges gas within the vortex chamber, generating a high-pressure, continuous airflow, enabling the hair dryer 100 to combine strong airflow with quiet operation. A jet device ejects a high-speed airflow from a nozzle, providing a gentler breeze and reducing irritation to hair or skin from strong airflow, thus improving the user experience.

[0049] For the hair dryer 100 of this application, multiple air ducts 11 may be equipped with the same or different blowing components 20. For example, some air ducts 11 may be equipped with fans with blades, some air ducts 11 may be equipped with piezo fans, and some air ducts 11 may be equipped with jet devices, so as to expand the blowing effect of the hair dryer 100 and broaden its application scenarios.

[0050] In some embodiments of this application, such as Figure 3 As shown, the hair dryer 100 may further include an air guide 40. The air guide 40 is disposed inside the air duct 11 and is arranged on the side of the blower 20 facing the air outlet 13. The air guide 40 is positioned close to the air outlet 13, which is located on the outer periphery of the air guide 40. The air guide 40 has an air guiding surface 401, which is inclined, allowing airflow to be guided by the air guiding surface 401 and output through the air outlet 13.

[0051] The air guide 40 is located between the blower 20 and the air outlet 13, and the air guide surface 401 is inclined. It can effectively guide the airflow output by the blower 20, avoid the airflow from generating eddies or backflow at the end of the air duct 11, and reduce ineffective energy loss. Furthermore, by guiding the airflow along the preset path, the airflow can converge and flow towards the outer periphery where the air outlet 13 is located, ensuring that more airflow can be directly output from the air outlet 13, thereby improving the air outlet efficiency of the air duct 11.

[0052] In this embodiment, the air outlets 13 are arranged on the outer periphery of the air guide 40, and multiple air outlets 13 form a circular structure. The inclined air guide surface 401 can divert the airflow in the central area to the surrounding areas, so that the air guide 40 guides the airflow to be evenly distributed to the multiple air outlets 13 on the outer periphery, ensuring the uniformity of the airflow. The air outlets 13 distributed on the outer periphery of the air guide 40, in conjunction with the inclined angle of the air guide surface 401, can make the airflow output from the air outlets 13 diffuse radially or in a ring shape, expanding the coverage area of ​​the airflow and improving the drying efficiency of the hair dryer 100.

[0053] In some examples, the air guide 40 includes a main body 41 and an extension 42. The main body 41 is a conical structure that is closed at one end and open at the other end. The extension 42 is open at both ends and hollow inside, and is connected to the end of the main body 41 that has an opening.

[0054] One end of the extension 42 away from the main body 41 is connected to the inner wall of the outer casing 10, where an air outlet 13 is provided. The air outlet 13 is arranged on the outer side of the extension 42. The outer surface of the extension 42 is an arc-shaped surface, and the outer surface of the main body 41 and the outer surface of the extension 42 form an air guide surface 401.

[0055] The main body 41 can initially guide the airflow output from the blower 20. When the airflow blows from the blower 20 to the main body 41, the inclined conical surface of the main body 41 can naturally guide the airflow in the central area to diffuse outward. In this example, the closed end of the main body 41 is arc-shaped, which can reduce the impact friction between the airflow and the guide surface 401, making the airflow diffusion process gentler and reducing energy loss in the initial guidance stage.

[0056] The extension 42 can guide and regulate the airflow diffused by the main body 41 for the second time. When the airflow diffused by the conical main body 41 comes into contact with the arc surface of the extension 42, it will naturally transition along the curved surface, so that the airflow direction is more in line with the outer periphery of the air outlet 13, ensuring that the airflow can be smoothly output through the air outlet 13, reducing air volume loss and improving the convergence efficiency of the airflow to the air outlet 13.

[0057] In this application, the hair dryer 100 has an air outlet channel 30 at each air outlet hole 13 corresponding to each air duct 11, and the air outlet direction of each air outlet channel 30 is different.

[0058] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the hair dryer 100 further includes an adjusting member 50, and each air duct 11 is provided with an adjusting member 50 corresponding to the air outlet 13. The adjusting member 50 is open at both ends and hollow inside. One end of the adjusting member 50 is connected to the position of the outer shell 10 corresponding to the air outlet 13, and the airflow output from the air outlet 13 can be blown out from the other end of the adjusting member 50. The interior of the adjusting member 50 forms an air outlet channel 30.

[0059] The adjusting member 50 is a flexible member that can deform and be fixed at a set angle. The angles at which the multiple adjusting members 50 on the outer shell 10 are fixed are different.

[0060] In this embodiment, the adjusting member 50 is a flexible and shape-adjustable structure. The user can manually bend the adjusting member 50 according to actual needs and fix it at a specific angle. Furthermore, according to the user's actual usage needs, the shaping angles of multiple adjusting members 50 can be adjusted to be different or some adjusting members 50 can be shaped to the same angle, so that the air outlet directions of different air ducts 11 can form different angle combinations to adapt to diverse scenario requirements.

[0061] The adjusting element 50 can be a metal flexible hose or a corrugated flexible hose. The metal flexible hose can be a spiral hose made of copper, aluminum or stainless steel. Its spiral winding structure can stably maintain its shape after being bent at any angle and is not easily deformed by airflow impact or slight external force, ensuring the accuracy of the air outlet direction after shaping.

[0062] The corrugated flexible hose can be made of plastic, silicone, or rubber, making bending easier and providing a more convenient user experience. Furthermore, the lightweight nature of plastic, silicone, or rubber materials reduces the overall weight of the hair dryer by 100%, preventing user fatigue during prolonged use.

[0063] Users can adjust the air ducts 11 using the adjustment piece 50 to create different airflow directions according to their needs, adapting to variations in hair type, hairstyle, and the areas being dried. Furthermore, adjusting the airflow direction expands the usage scenarios of the hair dryer 100; for example, angled airflow avoids direct airflow onto the scalp, while a slight bend allows for precise drying of residual moisture in hidden areas such as behind the ears and neck. In addition, users do not need to move the entire hair dryer 100 to change the airflow direction; they only need to adjust the adjustment piece 50, reducing arm movement and fatigue during prolonged use.

[0064] In some embodiments of this application, the channel of the air outlet 13 can form an air outlet channel 30. Different air outlet channels 30 correspond to different extension directions of the air outlet 13, so that the air outlet directions of multiple air outlet channels 30 are different.

[0065] By utilizing the air outlet 13 as a direct channel for airflow output, no additional independent connectors are needed, reducing the number of parts. This lowers the costs of mold development and material procurement, simplifies the production assembly process, and improves production efficiency. Furthermore, the airflow is directly blown out from the air duct 11 through the air outlet 13, resulting in a shorter and more direct path, concentrated airflow, and higher energy conversion efficiency. In addition, the extension direction of the outlet can be precisely set during the fabrication of the outer casing 10, ensuring that the hair dryer 100 can stably meet specific airflow requirements.

[0066] In some embodiments of this application, such as Figure 3As shown, the hair dryer 100 may further include a main control circuit board 60. The main control circuit board 60 is disposed inside the housing 10 and arranged in the functional area 102 of the housing 10. The blower element 20 is electrically connected to the main control circuit board 60 via wires, and the blower elements 20 in the plurality of air ducts 11 are respectively electrically connected to the main control circuit board 60 via wires.

[0067] The hair dryer 100 may also include a heating element 70, which is disposed in the air duct 11 and arranged on the side of the blower 20 facing the air outlet 13. The heating element 70 is electrically connected to the main control circuit board 60 via wires. The main control circuit board 60 can receive control commands and send control signals to the blower 20 and the heating element 70 to ensure that the components in the multiple air ducts 11 work together.

[0068] The heating element 70 can be a heating wire. The airflow generated by the hair dryer 20 can flow directly over the surface of the heating element 70, quickly absorbing the heat generated by the heating element 70 and forming hot air that flows out from the air outlet 13. The hot air acts on the hair, accelerating the evaporation of hair moisture and also assisting in styling the hair through temperature.

[0069] In some examples, the hair dryer 100 includes multiple control buttons 80, which are disposed on the surface of the housing 10 and are electrically connected to the main control circuit board 60. Each control button 80 establishes an electrical connection through the main control circuit board 60 to a blower element 20 and a heating element 70 inside an air duct 11, thereby controlling the blower element 20 and the heating element 70 in the corresponding air duct 11.

[0070] Each control button 80 corresponds to the blower 20 and heating element 70 of a single air duct 11. Users can adjust the working status of a certain air duct 11 individually according to the usage scenario without affecting other air ducts 11, thus realizing differentiated treatment of different areas and meeting the needs of fine drying, styling or care.

[0071] The hair dryer of this application has multiple independent air ducts inside its outer casing. Each air duct is independently equipped with an air inlet, an air outlet, and a blower component. The airflow can circulate independently within its respective air duct, effectively ensuring stable wind speed and pressure in all directions and improving overall drying efficiency. Furthermore, the air outlet directions of the multiple air ducts are different, allowing users to achieve multi-area airflow coverage without frequently adjusting the position of the hair dryer. This results in a more uniform and wider airflow distribution, effectively covering different areas of the object to be dried and enhancing the user experience.

[0072] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
