Description

Technical Field

[0001] This utility model specifically relates to a high-efficiency air nozzle. Background Technology

[0002] As people's demands for the performance of personal care appliances continue to increase, hair dryers, as a widely used hair styling tool in daily life, have evolved from simply "drying hair" to offering multiple functions such as "efficient drying, hair care and styling, and a comfortable experience." To meet the needs of different users for airflow, wind speed, temperature, and airflow modes, various nozzle accessories are widely used in hair dryers to achieve effects such as concentrated airflow, diffused soft airflow, and styling.

[0003] Most hair dryer nozzles on the market are static in structure, mainly including concentrator nozzles, diffuser nozzles, and styling nozzles. These nozzles typically adjust the airflow by changing the shape or cross-sectional area of ​​the air outlet, such as using a tapered channel to concentrate the airflow or a flared opening to diffuse it. However, these traditional nozzles have significant technical limitations: First, the airflow is a static, continuous flow with limited coverage, making it difficult to achieve uniform blowing over a large area, resulting in low drying efficiency; second, the airflow lacks dynamic variation characteristics and cannot simulate the alternating "hot air blow-drying + cold air setting" treatment mode used in professional hairstyling, affecting the final styling effect and hair health; third, when the user holds the nozzle close to the hair, the concentrated hot air can easily cause localized high temperatures, posing a risk of scalp burns or hair damage.

[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency air nozzle that is efficient, comfortable, and has the effects of hot air blowing and cold air shaping.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a high-efficiency nozzle, including a nozzle holder for connecting to a hair dryer. The nozzle holder has a through-flow air guide channel, and a baffle is provided in the air guide channel. The nozzle holder has an annular sliding groove on the side wall of the air guide channel. The baffle has a sliding part that is inserted into the annular sliding groove, allowing the baffle to rotate axially relative to the nozzle holder. The baffle has a blade in the middle that can push the baffle to rotate when airflow occurs in the air guide channel. The baffle has at least two blades, and the adjacent blades form an air guide outlet.

[0008] As described above, the high-efficiency air nozzle consists of a central column located in the middle, a sliding part that surrounds the central column in an annular shape, and blades that are located between the central column and the sliding part and are evenly distributed around the central column as the central axis.

[0009] As described above, the high-efficiency nozzle has curved blades with a forward-facing outlet surface and a rearward-facing windward surface. The two ends of the blades are connected to a central column and a sliding part, respectively. The two sides of the blades are the upper windward edge and the lower windward edge, respectively. The upper windward edge of each blade extends from the lower end of the central column to the sliding part, and the upper windward edge is connected to the sliding part at point A. The lower windward edge of each blade extends from the upper end of the central column to the sliding part, and the lower windward edge is connected to the sliding part at point B. All points A and B are located on the same sliding plane, which makes the lower windward edge of each blade located above the upper windward edge of the adjacent blade. The air outlet faces the outlet surface of the blade.

[0010] The high-efficiency air nozzle described above has three blades.

[0011] As described above, in the high-efficiency air nozzle, the air guide channel gradually expands from back to front, and the baffle is located in the front half of the air guide channel.

[0012] As described above, the high-efficiency nozzle has a detachable connection structure at the rear end of the nozzle holder for connecting to a hair dryer.

[0013] The high-efficiency nozzle described above includes a detachable connection structure comprising a magnetic element located at the rear end of the nozzle seat.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. Achieving automatic airflow rotation and wide-area diffusion significantly improves hair drying efficiency. By incorporating a rotatable airflow-driven baffle within the airflow channel, the main airflow from the hair dryer propels the baffle to rotate, dividing the airflow into multiple independent spiral streams that are blown out from the air outlet. This structure eliminates the need for an additional motor or power source, achieving dynamic airflow, greatly expanding the airflow coverage area, improving the uniformity of airflow on the hair surface and air circulation efficiency, thereby significantly shortening drying time.

[0016] 2. It features an alternating hot and cold airflow mode, combining the functions of hot styling and cold setting. As the spoiler rotates continuously, the hot airflow periodically sweeps across the hair while intermittently introducing surrounding cool air, simulating the "hot styling – cold setting" process in professional hair care. This dynamic alternation not only accelerates moisture evaporation but also effectively closes the hair cuticles, reduces heat damage, and enhances the durability and shine of the hairstyle, achieving both efficient drying and hair styling.

[0017] 3. The structure is safe and reliable, easy to use and prevents burns. It adopts a gradually expanding airflow channel and tangential air outlet design to fully diffuse the airflow, reducing the heat flux density per unit area and avoiding localized overheating. Users can operate the nozzle close to their hair without the risk of burns. Additionally, the nozzle holder has a magnetic detachable connection structure at the rear, allowing for quick and accurate installation, enhancing ease of use and user experience.

[0025] The utility model will be further described below with reference to the accompanying drawings:

[0026] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0027] This embodiment introduces a high-efficiency air nozzle, such as Figures 1 to 3As shown, the device includes a nozzle holder 1 for connection to a hair dryer A. The rear end of the nozzle holder 1 is connected to the air outlet A1 of the hair dryer A, so that the nozzle holder 1 has a through-flow air guide channel 10, allowing the airflow blown out by the hair dryer A to be concentrated or diffused through the air guide channel 10 before being blown out from the front side of the nozzle holder 1. A baffle 2 is provided within the air guide channel 10. The nozzle holder 1 has an annular sliding groove 11 on the side wall of the air guide channel 10. The baffle 2 has a sliding part 21 that inserts into the annular sliding groove 11, allowing the baffle 2 to rotate axially relative to the nozzle holder 1. The baffle 2 has blades 22 in its middle that can drive the baffle 2 to rotate when airflow appears in the air guide channel 10. The baffle 2 has at least two blades 22, and adjacent blades 22 form an air outlet 20. Structural principle explanation: When the blower A is working, a high-speed airflow P1 enters the air guide channel 10 from the air outlet A1 and acts on the surface of the blades 22 of the baffle 2. Due to the specific curved shape and windward angle of the blades 22, the airflow exerts a thrust on the blades, generating a torque around the central axis, thereby driving the baffle 2 to achieve self-rotation under the guidance of the sliding part 21 and the sliding groove 11. As the baffle 2 continues to rotate, the originally continuous main airflow is periodically divided into multiple sub-airflows, which are sequentially discharged through the air guide outlets 20 between adjacent blades, forming multiple independent airflows P2 with a spiral motion trend. This structure enables the airflow blown by the blower A to drive the baffle 2 to rotate, such as... Figures 3 to 6 As shown, the airflow P1 from the hair dryer A passes through the deflector 2 and exits from the air outlet 20, forming at least two independent airflows P2. Simultaneously, the rotation of the deflector 2 causes the airflow P2 to form a spiral vortex, significantly widening the airflow area and keeping the airflow dynamically changing. This significantly increases the coverage area of ​​the blower, effectively improving the efficiency of hair drying. More importantly, when the airflow P2 blows out hot air, during the continuous rotation of the deflector 2, the airflow periodically sweeps across the hair surface in space. Combined with the intermittent mixing of ambient cold air, this creates an alternating "hot and cold" effect on the hair surface. This not only increases the rate of moisture evaporation but also allows for rapid cooling and setting after heat styling, achieving a dual care function similar to "heat styling + cold setting" in professional hairdressing. Thus, while improving drying efficiency, it also provides the hair care and styling effects of heat styling and cold setting.

[0028] As a preferred option, such as Figures 3 to 6As shown, the aerodynamic spoiler 2 consists of a central column 23 located in the middle, a sliding part 21 forming a ring around the central column 23, and blades 22 evenly distributed around the central column 23 as the central axis, located between the central column 23 and the sliding part 21. The sliding part 21 is a ring structure surrounding the blades 22, and its shape is similar to or matches the sliding groove 11, thereby improving the connection strength and rotational stability of the aerodynamic spoiler 2. This integrated structural design helps to ensure the structural strength and rotational balance of the aerodynamic spoiler 2 under the impact of high-speed airflow, and reduces vibration and noise. In this embodiment, three blades 22 are provided, which means that three air outlets 20 are formed, thereby forming three independent airflows P2. The symmetrical layout of the three blades has good aerodynamic balance, which can avoid eccentric rotation and ensure uniform and stable airflow.

[0029] As a further optimization plan, such as Figure 6 and Figure 7As shown, the blade 22 is curved and has a front air outlet surface 221 facing forward and a rear windward surface 222. The two ends of the blade 22 are connected to the central column 23 and the sliding part 21, respectively. The two sides of the blade 22 are the upper wind side 223 and the lower wind side 224, respectively. That is, the airflow first passes through the upper wind side 223 of the blade 22 and then reaches the lower wind side 224. The upper windward edge 223 is connected to the sliding part 21 at point A. The lower windward edge 224 of each blade 22 extends from the upper end of the central column 23 to the sliding part 21, and is connected to the sliding part 21 at point B. All points A and B are located on the same sliding plane, that is, the sliding part 21 is an annular thin plate on a sliding plane, and all points A and B are connected on this sliding plane. Preferably, the point A of the blade 22 basically coincides with the point B of the adjacent blade 22, and is connected at the same position of the sliding part 21. This makes the lower windward edge 224 of the blade 22 located above the upper windward edge 223 of the adjacent blade 22, and thus the air guide outlet 20 faces the air outlet surface 221 of the blade 22. This staggered arrangement means that the air guide outlet 20 formed between adjacent blades is not straight along the axial direction, but has a certain circumferential tilt angle. Specifically, because the leeward side 224 is higher than the adjacent upwind side 223, the airflow is forced to move along a spiral trajectory when passing through the air guide outlet 20, thereby enhancing the tangential velocity component of the outlet airflow. This design cleverly converts some of the axial kinetic energy into rotational kinetic energy, giving the outlet airflow P2 stronger diffusion and entrainment capabilities, effectively driving the surrounding air to participate in the flow, and further expanding the actual effective wind area. With the above structure, the airflow P1 blown out by the hair dryer A first reaches the windward surface 222 of the blade 22. The curved windward surface 222 drives the deflector 2 to rotate. Since the lower windward side 224 of the blade 22 is located above the upper windward side 223 of the adjacent blade 22, the air outlet 20 formed by the upper windward side 223 and the lower windward side 224 of the adjacent blade 22 is oriented roughly tangentially to the circumference. That is, when the airflow is blown out, the airflow P2 blows directly towards the air outlet surface 221 of the blade 22, which greatly increases the degree of airflow diffusion. This results in a very wide airflow area after the airflow is blown out, which allows the high-efficiency nozzle to be close to the hair for drying, making it less likely to cause burns. This is because the wide-angle diffused airflow reduces the heat flux density per unit area, avoiding local high temperature accumulation. At the same time, the rotation of the deflector 2 causes the airflow P2 to rotate continuously, forming an alternating hot and cold air effect on the hair surface, achieving a high-efficiency, uniform blow-drying effect with cooling and styling functions.

[0030] As a preferred option, such as Figures 1 to 3As shown, the air guide channel 10 gradually expands from back to front, creating a diffused airflow effect and further increasing the airflow area of ​​the hair. This gradually expanding channel design conforms to the subsonic diffusion principle in fluid mechanics, which helps to reduce airflow velocity, increase static pressure, and allow the airflow to enter the turbulence area more smoothly, reducing turbulence losses. At the same time, the turbulence-inducing element 2 is set in the front half of the air guide channel 10, so that the airflow is fully expanded before being divided and rotated by the turbulence-inducing element, thereby enhancing the continuity and stability of the airflow rotation and making the spiral curl effect more obvious.

[0031] As a preferred option, such as Figure 2 and Figure 3 As shown, the nozzle holder 1 has a detachable connection structure at its rear end for connecting a hair dryer. This detachable connection structure includes a magnetic component 12 located at the rear end of the nozzle holder 1, enabling quick installation and removal via magnetic attraction. This eliminates the need for screw tightening or clip pressing, greatly improving ease of use and user experience. The magnetic connection also provides excellent sealing and coaxial alignment, ensuring smooth airflow and preventing air leakage or eccentric disturbance. This design is particularly suitable for applications requiring frequent nozzle changes or one-handed operation.
