Description

Technical Field

[0001] This utility model relates to the technical field of hair curler nozzles, and in particular to a hair restraint structure for a two-way airflow hair curler. Background Technology

[0002] The curling nozzle is an accessory for high-speed hair dryers, primarily used for curling hair and helping beauty enthusiasts create different curly hairstyles.

[0003] Currently, the curling nozzles on high-speed hair dryers often cause hair to slide back and forth on the surface, and the hair tends to clump together. This is because the nozzle surface is generally smooth and lacks a design to restrain the hair. Under external force and the user's angle, the hair easily slides back and forth on the curling nozzle surface during styling, for example, sliding from one end closer to the main unit to the other, increasing the difficulty of styling. This leads to the following problems:

[0004] 1. Currently, the curling nozzles of competing high-speed hair dryers are mostly cylindrical in shape with a smooth, linear surface, which cannot flexibly restrain the hair to prevent it from slipping.

[0005] 2. Currently, the air outlet adopts a straight shape, and its length is the same as the length of the curling iron nozzle. If the curling iron is short, its air outlet outline length is also short. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of existing hair curling nozzles, which have a linearly smooth surface that makes hair prone to slipping, and provides a hair restraint structure for a two-way airflow hair curling nozzle that can flexibly restrain hair and prevent it from slipping.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A hair restraint structure for a two-way airflow hair curler, comprising:

[0009] The main body of the nozzle is cylindrical in shape, and its side wall has several air outlet areas evenly distributed along the circumference of the main body.

[0010] Several guide vanes are detachably connected to several air outlet areas and located outside the nozzle body. The left and right edges of the guide vanes and the side wall of the nozzle body respectively form an air outlet facing left and an air outlet facing right. The length direction of the air outlet is parallel to the axis of the nozzle body. The outer surface of the guide vanes is an arc-shaped surface with both left and right edges curving inward and the middle part arching outward. The outer surface of the guide vanes forms a wave-like structure with high and low undulations from one end to the other. The left and right edges of the air guide blades are air outlets with opposite airflow directions, allowing users to switch between different air outlet directions by manipulating the relevant components on the nozzle body to achieve bidirectional airflow according to actual needs. The air guide blades are made of flexible materials, such as high-temperature resistant rubber. At the same time, the outer surface of the air guide blades adopts a wave-like structure with varying heights, which can flexibly restrain the hair when curling, preventing the hair from slipping in the curling area of ​​the curling barrel, improving the completion and efficiency of curling, thus achieving the purpose of flexibly restraining the hair and preventing it from slipping.

[0011] Preferably, the left and right edges of the guide vane have a wavy structure from one end to the other. The edge of the guide vane at the air outlet adopts an original wavy profile, which greatly increases the length of the air outlet, improves the actual air passage area, optimizes the styling effect on the hair, and allows the hot air to dry and style the hair at different distances during air outlet, thus protecting hair health.

[0012] Preferably, the sidewall of the nozzle body includes several side plates, the outer side of which is an outwardly arched arc structure. The air outlet area is formed between every two adjacent side plates. The air outlet area is provided with a rectangular strip and two parallel rectangular air vents, which are located on the left and right sides of the rectangular strip respectively. The rectangular air vents and the rectangular strip are parallel to the length direction of the side plates. The rectangular air vents are provided with several spaced stiffeners, which are evenly distributed along the length direction of the rectangular air vents. One end of the stiffener is fixedly connected to the sidewall of the rectangular strip, and the outer side of one end of the stiffener is connected to the outer side of the rectangular strip. The inner side of the other end of the stiffener is fixedly connected to the outer edge of the side plate. The guide vanes cover the rectangular air vents on both sides of the corresponding rectangular strip. The center of the guide vanes is detachably connected to the rectangular strip. The air outlet is formed by the side edge of the corresponding guide vane and the outer edge of the corresponding side plate. The outer side of the side plate has an outward arched arc structure, which makes it easy to achieve curly hair styling. At the same time, one end of the rib plate is fixedly connected to the side wall of the rectangular strip, and the outer side of this end is connected to the outer side of the rectangular strip. The inner side of the other end of the rib plate is fixedly connected to the outer edge of the side plate. The air outlet allows airflow to pass through through the flexible surface of the guide vanes, presenting an outer high and inner low configuration, which guides the airflow to fully reach the farthest end of the air duct inside the nozzle body, so that the airflow fills the air duct and then blows out from the air outlet in a consistent manner.

[0013] Preferably, the outer side of the rib plate is an outwardly arched arc, and the left and right inner surfaces of the guide vanes are respectively matched and fitted with the outer side of the corresponding rectangular air outlet inner rib plate. The air outlet direction is the same as the tangential direction of the outer side of its adjacent side plate. The outwardly arched arc of the rib plate and the matching of the left and right inner surfaces of the guide vanes with the outer side of the corresponding rectangular air outlet inner rib plate result in a certain curvature on the inner surface of the guide vanes. The design of the inner surface contour and air outlet angle of the guide vanes ensures that after the airflow exits from inside the curling iron nozzle, it forms a slit when flowing over the surface of the nozzle body. This allows the high-speed airflow to cut across the nozzle surface, creating a Coanda effect that causes hair to automatically adhere to the surface of the curling iron nozzle. This design ensures reliable hair adhesion.

[0014] Preferably, the radial distance from the highest point of the arc-shaped protrusion to the nozzle body is the same as the radial distance from the highest point of the outer protrusion of the side plate to the nozzle body. This results in the side plate and guide vanes forming an approximately cylindrical structure, which facilitates curly hair styling and provides better protection for the hair.

[0015] Preferably, a positioning protrusion is fixed on the rectangular strip, and a positioning groove matching the positioning protrusion is provided at the center of the inner side of the guide vane. Several hooks are fixed on both the left and right inner surfaces of the guide vane, and these hooks are evenly distributed along the length of the guide vane. The guide vane is detachably connected to the air outlet area by matching the hooks with the corresponding stiffeners. The use of stiffeners to design a suspension scheme for the guide vane allows for reliable installation on the nozzle body, ensuring that the left and right air outlet dimensions are completely consistent after installation, and improving the installation process and efficiency.

[0016] The beneficial effects of this utility model are:

[0017] 1. The unique design of the outer side of the guide blades and the main structure of the nozzle allow for flexible restraint of the hair during curling. This prevents the hair from slipping in the curling area of ​​the curling barrel, improving the curling completion and efficiency, thus achieving the goal of flexibly restraining the hair and preventing it from slipping.

[0018] 2. The air outlet uses a flexible surface to allow airflow to pass through and presents a high outer and low inner configuration, which guides the airflow to fully reach the far end of the air duct, so that the airflow fills the air duct and then blows out of the air outlet in a consistent manner.

[0019] 3. The design of the internal surface contour and air outlet angle of the guide vanes makes the airflow form a slit when it flows through the surface of the nozzle body after it comes out of the curling nozzle. This allows the high-speed airflow to cut through the nozzle surface and flow through it, creating the Coanda effect, which makes the hair automatically adhere to the surface of the curling nozzle. This design makes the hair adhesion effect reliable.

[0020] 4. The guide vanes at the air outlet feature a unique wave-shaped profile, which significantly increases the length of the air outlet, improves the actual airflow area, optimizes the styling effect on the hair, and allows the hot air to dry and style the hair from different distances, protecting hair health.

[0021] 5. The suspension scheme for the guide vanes is designed using stiffeners, which allows the guide vanes to be reliably installed on the nozzle body, and ensures that the dimensions of the left and right air outlets are completely consistent after the guide vanes are installed. This also improves the installation process and efficiency. Attached Figure Description

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a hair-restraining structure for a bidirectional air-venting hair curler includes a nozzle body 1, which is cylindrical in shape, with several air outlet areas 2 evenly distributed circumferentially along its sidewalls; several guide vanes 3, detachably connected to the air outlet areas 2 and located outside the nozzle body 1, with the left and right edges of the guide vanes 3 forming left-facing and right-facing air outlets 4 respectively between them and the sidewalls of the nozzle body 1. The length direction of the air outlets 4 is parallel to the axial direction of the nozzle body 1. The outer surface of the guide vanes 3 is an arc-shaped surface with both left and right edges curving inwards and the middle part arching outwards, forming a wavy structure from one end to the other. The left and right edges of the guide vanes 3 exhibit a wavy structure from one end to the other.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sidewall of the nozzle body 1 includes several side plates 5. The outer side of the side plate 5 is an outwardly arched arc structure. The air outlet area 2 is formed between each pair of adjacent side plates 5. The air outlet area 2 is provided with a rectangular strip 6 and two parallel rectangular air vents 7. The two rectangular air vents 7 are located on the left and right sides of the rectangular strip 6, respectively. The rectangular air vents 7 and the rectangular strip 6 are parallel to each other in the length direction of the side plate 5. The rectangular air vents 7 are provided with several spaced stiffeners 8. The stiffeners 8 are evenly distributed along the length direction of the rectangular air vents 7. One end of the stiffener 8 is fixedly connected to the sidewall of the rectangular strip 6. The outer side of one end of the stiffener 8 is connected to the outer side of the rectangular strip 6. The inner side of the other end of the stiffener 8 is fixedly connected to the outer edge of the side plate 5. The guide vanes 3 cover the rectangular air vents 7 on both sides of the corresponding rectangular strip 6. The center of the guide vanes 3 is detachably connected to the rectangular strip 6. The air outlet 4 is formed by the side edge of the corresponding guide vane 3 and the outer edge of the corresponding side plate 5.

[0034] like Figure 3 and Figure 4 As shown, the outer side of the stiffener 8 is an outwardly arched arc. The two inner surfaces of the guide vanes 3 match and fit with the outer side of the corresponding rectangular air outlet 7. The air outlet 4 has the same air outlet direction as the tangent direction of the outer side of its adjacent side plate 5. The radial distance from the highest point of the arc-shaped protrusion to the air nozzle body 1 is the same as the radial distance from the highest point of the outer side of the side plate 5 to the air nozzle body 1.

[0035] like Figure 3 and Figure 5 As shown, a positioning protrusion 9 is fixed on the rectangular strip 6, and a positioning groove 10 matching the positioning protrusion 9 is provided on the inner center of the guide vane 3. Several hooks 11 are fixed on both the left and right inner surfaces of the guide vane 3. The several hooks 11 are evenly distributed along the length direction of the guide vane 3. The guide vane 3 can be detachably connected to the air outlet area 2 by matching the corresponding stiffener 8 through the hooks 11.

[0036] The guide blades 3 are made of flexible materials, such as high-temperature resistant rubber, and the number of guide blades 3 is generally 4 to 8. At the same time, the outer surface of the guide blades 3 adopts a wave-shaped structure with varying heights, which can flexibly restrain the hair when curling, and prevent the hair from slipping in the curling area of ​​the curling barrel when shaping the hair, thereby improving the completion and efficiency of curling. This achieves the purpose of flexibly restraining the hair and preventing it from slipping. The difference in size between the high and low ends of the outer surface of the guide blades 3 is 0.5mm to 2.5mm, which can be matched according to parameters such as the number of blades and the diameter of the curling barrel nozzle. The edge of the guide blades 3 at the air outlet 4 adopts an original wave-shaped contour with a wave depth of 0.5mm to 3mm, which greatly increases the length of the air outlet 4, increases the actual air passage area, optimizes the styling effect on the hair, and allows the hot air to dry and style the hair at different distances when it is venting, protecting the hair health. The width of the air outlet 4, which is formed by the guide blades 3 and the nozzle body 1, is 0.35 to 0.6mm.

[0037] One end of the stiffener 8 is fixedly connected to the side wall of the rectangular strip 6 and the outer side of this end is connected to the outer side of the rectangular strip 6. The inner side of the other end of the stiffener 8 is fixedly connected to the outer edge of the side plate 5. The air outlet 4 allows airflow to pass through through the flexible surface of the guide vane 3 and presents a high outer and low inner configuration, which guides the airflow to fully reach the farthest end of the air duct inside the nozzle body 1, so that the airflow fills the air duct and then blows out from the air outlet 4 in a consistent manner.

[0038] The outer side of the rib plate 8 is an outwardly arched arc. The two inner surfaces of the guide vane 3 match and fit with the outer side of the inner rib plate 8 of the corresponding rectangular air outlet 7, so that the inner surface of the guide vane 3 also has a certain curvature. The design of the inner surface contour and air outlet angle of the guide vane 3 makes the airflow form a scissor when it flows through the surface of the air outlet body 1 after it comes out from inside the hair curler nozzle. This allows the high-speed airflow to cut through the surface of the air outlet and flow through it, forming the Coanda effect, which makes the hair automatically adsorbed onto the surface of the hair curler nozzle. This design makes the hair adsorption effect reliable, and the hair restraint system on the surface can be used to personalize the hair according to the needs of the styling.

[0039] The suspension scheme of the guide vane 3 is designed using the stiffener 8, which allows the guide vane 3 to be reliably installed on the nozzle body 1, and ensures that the dimensions of the left and right air outlets 4 are completely consistent after the guide vane 3 is installed, and improves the installation process and efficiency.
