Hair dryers typically have heating elements and temperature control devices inside to heat the airflow. Hair dryers can dry wet hair or style and condition hair. However, the high-speed movement of the airflow from the air inlet to the outlet can easily lead to uneven airflow, and the airflow speed exceeding the speed of the surrounding air can cause instability in the interaction forces between air molecules, resulting in turbulence and affecting the hair dryer's airflow performance.

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] Hair dryers or hair care devices use airflow and heating to dry, style, or care for hair. Taking a hair dryer as an example, the motor drives the impeller to rotate, generating a high-speed airflow. The airflow is blown out from the nozzle. The speed of the airflow exceeds the speed of the surrounding air, causing the interaction forces between air molecules to become unstable, easily forming vortices and turbulence, causing airflow disturbance. This results in some of the airflow from the hair dryer being turbulent. Turbulent airflow leads to uneven airflow, affecting drying efficiency. In addition, during the drying process, turbulent airflow can cause some hair cuticles to flip up in the opposite direction, making some hair frizzy after drying. Turbulent airflow can also affect the styling effect.

[0037] This invention provides an air outlet component 100, which can be applied to air outlet devices such as hair dryers 10 and hair care devices. The air outlet component 100 can stabilize and comb the airflow blown from the air outlet 140, improving the uniformity and stability of the airflow. The air outlet component 100 of this invention can be directly mounted on electrical appliances such as hair dryers 10 and hair care devices, or as an accessory. Users can selectively install it on electrical appliances such as hair dryers 10 and hair care devices according to their actual usage needs.

[0038] Combination Figure 1 , Figure 3 and Figure 5 According to an embodiment of the present invention, the air outlet assembly 100 includes an air duct 110, a first air guide plate 120, and a baffle 130. The air duct 110 has a first end 110a and a second end 110b opposite to each other. The first end 110a of the air duct 110 is closed and the second end 110b is open. The air outlet direction can be from the first end 110a to the second end 110b of the air duct 110, that is, the airflow can flow from the first end 110a to the second end 110b, and the airflow is discharged near the second end 110b. The first air guide plate 120 is connected to the air duct 110 and is configured to expand outward in the air outlet direction from the first end 110a to the second end 110b of the air duct 110. The baffle 130 surrounds the first air guide plate 120 and forms an air outlet 140 between the baffle 130 and the first air guide plate 120. That is, the air duct 110 and the air outlet 140 are separated by the first air guide plate 120.

[0039] Specifically, the first end 110a of the air duct 110 is closed, and the second end 110b is open. Airflow exits near the second end 110b. Part of the vortex blown out from the air outlet 140 enters the air duct 110 from the second end 110b. The air duct 110 can collect and organize the turbulent airflow near its central axis, reducing airflow disturbance near the central axis, thereby ensuring that the airflow from the air outlet 140 is uniform and smooth. In addition, the first guide plate 120 can guide the airflow at the air outlet 140, improving the smoothness and efficiency of airflow. Furthermore, the first guide plate 120 can separate the air duct 110 from the air outlet 140, which can improve the stabilization effect of the air duct 110 on the airflow along its central axis.

[0040] According to the air outlet assembly 100 of the present invention, the first air guide plate 120 guides the airflow and improves the stability of the air outlet, and the air duct 110 can sort and guide the airflow blown out of the air outlet 140 to reduce the disturbance of the airflow. Through the cooperation of the air duct 110 and the first air guide plate 120, the air outlet is smooth and uniform.

[0041] Combination Figure 5 The first air guide plate 120 extends outward in the air outlet direction of the air duct 110. The inner periphery of the first air guide plate 120 is connected to the air duct 110, and the outer periphery gradually expands outward from the first end 110a to the second end 110b to guide the airflow. The airflow can be effectively and smoothly blown out from the air outlet 140 formed between the first air guide plate 120 and the baffle 130, resulting in high air outlet efficiency of the air outlet assembly 100. Furthermore, the air duct extends along the air outlet direction and is connected to the inner periphery of the first air guide plate. By setting the air duct, the airflow blown out after being guided by the first air guide plate can be combed and guided, reducing airflow disturbance and making the air outlet smooth and uniform.

[0042] Combination Figures 1 to 5For example, the air outlet assembly 100 of the present invention can be applied to a hair dryer 10. The hair dryer 10 may include an airflow drive member 310, which drives the airflow from the air inlet to the air outlet 140. The air outlet 140 is formed between the first air guide plate 120 and the surrounding plate. The first air guide plate 120 can guide the airflow to the air outlet 140, thereby improving the airflow efficiency and smoothness. It is understood that when the airflow is blown out from the air outlet 140, reflection, refraction and interference phenomena are likely to occur, resulting in airflow disturbance and airflow turbulence. By setting the air duct 110, the vortex formed by the airflow blown out from the air outlet 140 enters the air duct 110 from the open position of the second end 110b of the air duct 110. The air duct 110 can gather the airflow to organize the airflow. The organized airflow is blown out to a position away from the air duct 110, thereby reducing the airflow disturbance near the central axis of the air duct 110. After being guided by the first air guide plate 120, the airflow is blown out from the air outlet 140. The air tube 110 organizes the airflow blown out from the air outlet 140, making the airflow of the hair dryer 10 smooth and even, which helps to improve the drying efficiency of the hair dryer 10. The airflow is evenly covered on the hair, which helps to maintain the smoothness of the hair and avoids the problem of frizz and roughness caused by disordered airflow after drying.

[0043] Combination Figure 5 Furthermore, a second air guide plate 131 may be provided on the baffle 130. The second air guide plate 131 and the first air guide plate 120 are opposite each other in a direction perpendicular to the axis of the air duct 110. Specifically, an air outlet 140 may be formed between the second air guide plate 131 and the first air guide plate 120. By setting the first air guide plate 120 and the second air guide plate 131 to cooperate, the airflow is guided so that the airflow can be blown out through the air outlet 140 efficiently, thereby improving the air outlet efficiency and air outlet smoothness.

[0044] Combination Figure 5 In some embodiments of the present invention, the second air guide plate 131 and the first air guide plate 120 may gradually move closer together in the air outlet direction so that the airflow is gathered and blown out from the air outlet 140, thereby further improving the air outlet efficiency.

[0045] The first air guide plate 120 and the second air guide plate 131 gradually converge in the air outlet direction. The first air guide plate 120 and the second air guide plate 131 can extend in a straight line or an arc along the air outlet direction, which can all converge the airflow.

[0046] Combination Figure 5 In some embodiments of the present invention, the second air guide plate 131 can gradually retract in the air outlet direction. The first air guide plate 120 and the second air guide plate 131 work together to guide the airflow to the air outlet 140. The gradually retracting structure enables the airflow to be gathered and blown out from the air outlet 140, thereby improving the air outlet efficiency and smoothness.

[0047] Combination Figure 5 In some embodiments of the present invention, the second air guide plate 131 may be configured to extend in a straight line inclined along the air outlet direction, which can better guide the airflow, make the airflow smooth, improve the stability of the airflow process, and further improve the air outlet efficiency and smoothness.

[0048] Combination Figure 5 In some embodiments of the present invention, the first air guide plate 120 is configured to extend in a straight line inclined along the air outlet direction, which can better guide the airflow, make the airflow smooth, improve the stability of the airflow process, and further improve the air outlet efficiency and smoothness.

[0049] Combination Figures 1 to 3 In some embodiments of the present invention, the air outlet 140 may be configured as an annular shape surrounding the air duct 110. The cross-section of the air outlet 140 may include a tapered section 141 and a straight section 142. The tapered section 141 tapers in the air outlet direction to connect with the straight section 142. The tapered section 141 can concentrate the airflow, and the straight section 142 allows the airflow to be blown out of the air outlet 140 smoothly. The tapered section 141 and the straight section 142 work together to improve the efficiency of air outlet and allow the airflow to be blown out of the air outlet 140 smoothly, and also to increase the air outlet speed of the air outlet assembly 100.

[0050] Combination Figure 1 and Figure 3 In some embodiments of the present invention, a plurality of support ribs 150 may be provided between the baffle 130 and the air guide plate. The plurality of support ribs 150 may be evenly spaced along the circumference of the first air guide plate 120. The support ribs 150 are respectively connected to the first air guide plate 120 and the baffle 130. The plurality of support ribs 150 make the first air guide plate 120 and the baffle 130 stably connected, thereby improving the structural stability of the air guide plate and the baffle 130.

[0051] Furthermore, the support ribs 150 can be positioned close to the air outlet plane 143 of the air outlet 140, where the air outlet plane 143 refers to the plane formed when the airflow leaves the air outlet assembly 100 from the air outlet 140. The support ribs 150 can be spaced apart near the air outlet plane 143, forming multiple fixed openings on the air outlet plane 143. The airflow is blown out from these multiple fixed openings. Compared to a single airflow being blown out, the support ribs 150 have a sorting effect on the airflow, especially for turbulent airflow near the central axis of the air outlet duct 110, which has an initial sorting effect, helping to reduce turbulence from the front end of the air outlet. The airflow blown out from the air outlet 140 can further reduce turbulence through the air outlet duct 110.

[0052] Specifically, the first air guide plate 120 and the baffle 130 work together to guide the airflow so that the airflow can flow through the air outlet 140 efficiently and smoothly. The support rib 150 can pre-sort the turbulent airflow at the air outlet 140. The airflow blown out from the air outlet 140 is further sorted through the air duct 110, which effectively reduces the turbulence of the airflow and makes the airflow smoother, thereby improving the air outlet effect of the air outlet assembly 100.

[0053] In some embodiments of the present invention, the width of the support rib 150 along the circumferential direction of the air guide plate ranges from 2.1mm to 3.9mm, so as to effectively tidy up the turbulent airflow at the air outlet 140 in the early stage.

[0054] Furthermore, the width of the aforementioned support rib 150 can be in the range of 2.5mm-3.5mm. Preferably, the width of the support rib 150 is 3mm. The support rib 150 has high stability and can set the spatial interval at the air outlet 140, allowing the airflow to be blown out in multiple fixed opening spaces. It has a good effect on sorting out the turbulent airflow at the air outlet 140, effectively helping to reduce the turbulent airflow at the front end of the air outlet, and can effectively support the first air guide plate 120 and the baffle 130.

[0055] In some embodiments of the present invention, the second end 110b of the duct 110 may be flush with the air outlet plane 143 of the air outlet 140. In this way, the duct 110 can effectively sort and guide the airflow on the air outlet plane 143, reduce the airflow circulation near the air outlet 140, and enable most of the airflow near the central axis of the air outlet assembly 100 to flow in a direction away from the air outlet 140, so that the airflow is smooth and the noise caused by airflow disturbance can be reduced.

[0056] Alternatively, the second end 110b of the duct 110 may protrude from the air outlet plane 143 of the air outlet 140. In this way, the duct 110 can effectively streamline the airflow on the air outlet plane 143, reduce airflow circulation near the air outlet 140, and allow most of the airflow near the central axis of the air outlet assembly 100 to flow away from the air outlet 140, resulting in smooth airflow and reducing abnormal noise caused by airflow disturbance.

[0057] Combination Figure 5In some embodiments of the present invention, the duct 110 may include a cylinder 111 and a cover plate 112. The cover plate 112 may be located at the first end 110a of the duct 110 and cover the cylinder 111. The cylinder 111 may be cylindrical, and the cover plate 112 may be hemispherical. Airflow may be blown out from the air outlet 140, and some turbulent airflow enters the cylinder 111. By covering the cylinder 111 with the cover plate 112, the duct 110 can gather the airflow near its central axis, sort and guide it. The cylindrical duct 110 and the hemispherical cover plate 112 can improve the wind gathering effect, provide traction force to the airflow, guide the airflow to move in the direction of extension of the flow stabilizing structure, and save space in the air outlet assembly 100.

[0058] Furthermore, the cylinder 111 and the air outlet assembly 100 can be coaxially arranged, that is, the central axis of the cylinder and the central axis of the air outlet assembly are located at the same position, which can make the air outlet assembly 100 symmetrical or regularly arranged relative to the central axis, and the air duct 110 can effectively guide the airflow around the central axis, avoiding new turbulence problems caused by uneven airflow layout relative to the central axis.

[0059] In some embodiments of the present invention, the first air guide plate 120 may be annular, with its inner periphery connected to the outer periphery of the air duct 110, and the first air guide plate 120 being close to the second end 110b of the air duct 110. In this way, the air outlet 140 and the air duct 110 can be separated by the first air guide plate 120. The first air guide plate 120 can effectively guide the airflow, allowing the airflow to flow smoothly and efficiently to the air outlet 140, and can also transition the turbulent airflow at the air outlet 140, making it easier for the air duct 110 to sort and guide the turbulent airflow at the air outlet 140, thereby improving the airflow stabilization effect of the air duct 110 at the air outlet 140 and reducing turbulence.

[0060] Combination Figures 1 to 5According to an embodiment of the present invention, the air outlet assembly 100 includes an air duct 110, a first air guide plate 120, and a baffle 130. The air duct 110 includes a cylindrical body 111 and a hemispherical cover plate 112. The first end 110a of the air duct 110 is sealed by the cover plate 112, and the second end 110b is open. Airflow flows from the first end 110a to the second end 110b. The first air guide plate 120 is annular, and the inner periphery of the first air guide plate 120 is connected to the outer periphery of the air duct 110, and is configured to extend from the first end 110a to the second end 110b. The air outlets at both ends 110b extend outwards in the air outlet direction. The first guide plate 120 is close to the second end 110b of the air duct 110. A second guide plate 131 may be provided on the baffle 130. The first guide plate 120 and the second guide plate 131 are opposite each other in a direction perpendicular to the axial direction of the air duct 110. An air outlet 140 is formed between the first guide plate 120 and the second guide plate 131. The first guide plate 120 and the second guide plate 131 gradually approach each other in the air outlet direction and both extend in a straight line inclined in the air outlet direction. The cross-section of the air outlet 140 includes a tapering section 14. 1. A straight section 142 and a tapering section 141 are connected to the straight section 142 in the air outlet direction. A plurality of support ribs 150 are connected between the air guide plate and the baffle 130. The plurality of support ribs 150 are arranged at intervals along the circumference of the first air guide plate 120, and the support ribs 150 are respectively connected to the air guide plate and the baffle 130. The support ribs 150 are set close to the air outlet plane 143 of the air outlet 140. The second end 110b of the air duct 110 is flush with or protrudes from the air outlet plane 143 of the air outlet 140. According to the present invention In the embodiment of the air outlet assembly 100, the first air guide plate 120 and the second air guide plate 131 cooperate to guide the airflow of the air outlet 140, thereby improving the air outlet efficiency. The support ribs 150 set the space between the air outlet 140 and the air outlet plane 143. The airflow is blown out from multiple fixed opening spaces, which helps to reduce turbulence at the front end of the air outlet. The air duct 110 can further comb and guide the airflow blown out of the air outlet 140 to reduce turbulence. The combed airflow flows away from the air outlet 140, making the air outlet smooth and improving the blowing effect.

[0061] Combination Figure 2 and Figure 4 The present invention provides a hair dryer 10, which may include a handle portion 200, a main body portion 300, and the aforementioned air outlet component 100. An air inlet may be disposed on the handle portion 200, the main body portion 300 is connected to the handle portion 200, and the air outlet component 100 may be disposed at one end of the main body portion 300. Optionally, the main body portion 300 may also be provided with an air inlet; that is, the hair dryer 10 may be a single-air-inlet structure with the handle, or a dual-air-inlet structure with both the handle and the main body portion 300. When the hair dryer 10 is a dual-air-inlet structure, the air inlet of the main body portion 300 may be disposed at the other end of the main body portion 300.

[0062] Furthermore, the hair dryer 10 may also include an airflow drive component 310, which may be disposed on the handle portion 200 and drive the airflow from the air inlet to the air outlet 140. A heating wire may also be provided on the airflow path from the air inlet to the air outlet 140 to heat the airflow. An air outlet 140 may be formed between the first air guide plate 120 and the second air guide plate 131. The airflow is guided by the first air guide plate 120 and the second air guide plate 131 to improve the smoothness and efficiency of the airflow.

[0063] Combination Figure 4 In some embodiments of the present invention, the hair dryer 10 may also include a rear cover plate 320, which can cover the other end of the main body 300. That is, the hair dryer 10 may have a single air inlet structure for the handle 200. A light body may be provided on the other end of the main body 300 so that the hair dryer 10 has a light display function, for example, to provide a prompt when the hair dryer 10 is turned on or when the speed is adjusted, thereby improving the user's interactive experience when using the hair dryer 10.

[0064] Combination Figure 3 and Figure 5 In some embodiments of the present invention, the hair dryer 10 may further include an air outlet baffle 160 located around the air outlet 140. The air outlet baffle 160 protrudes from the air outlet plane 143 of the air outlet 140, which can gather the airflow blown out of the air outlet 140, prevent the airflow from spreading after being blown out of the air outlet 140, reduce noise, and reduce the turbulence caused by the diverging flow of the airflow to a certain extent.

[0065] Furthermore, the outer surface of the air outlet baffle 160 can form part of the outer surface of the hair dryer 10. The air outlet baffle 160 is arranged around the air outlet plane 143, which can gather the airflow blown out by the hair dryer 10, prevent the blown airflow from being diffused, and further improve the uniformity of the airflow blown by the hair dryer 10.

[0066] Combination Figure 6 and Figure 7 , Figure 6 The diagram shows a simulated airflow pattern of the air outlet assembly 100 of the hair dryer 10, which does not have a blower tube 110 but only a first air guide plate 120. As can be seen from the diagram, there is localized airflow circulation near the central axis, and the airflow turbulence is obvious. Figure 7 The figure shows a simulation diagram of the hair dryer 10 according to an embodiment of the present invention. As can be seen from the figure, by setting the air duct 110, most of the airflow near the central axis flows away from the air outlet 140, and only a small amount of airflow circulates, which effectively reduces the turbulence of the airflow, makes the airflow smooth, and improves the air output effect of the hair dryer 10.
