Description

Technical Field

[0001] The utility model relates to the technology of hairdressing products, in particular to a hair straightener dryer. Background Art

[0002] In daily life, hair straighteners are often used to straighten hair to achieve hairdressing effects. Most traditional hair straighteners simply use a heating plate to clamp the hair and heat it to straighten it. A few straightening combs also have a blow-drying function, which can dry the hair while combing it. However, there are few dual-function hairdressing appliances with heating straighteners and hair dryers.

[0003] For example, a hair straightening blow-drying comb with Chinese utility model patent application number 202223012232.8 has an air duct inside, and there is an obvious height difference between the main air duct and the transition air duct, and the height difference is connected by a right-angle stepped transition section. Figure 1 The simplified structure between the main air duct 1 and the transition air duct 2 is shown. This structural design has the following defects: when strong winds blow toward the retaining wall 3 between the main air duct and the transition air duct, on the one hand, the wind is blocked and rebounds, and on the other hand, the right-angle step transition section 4 cannot smooth the transition of the strong wind, and there is still a lot of wind noise.

[0010] As a preferred solution, the bottoms of the transition section and the air outlet section are flush, the smooth curved surface is arranged on the top and / or both sides of the transition section and the air outlet section, and the transition section is equipped with a motor and a heater.

[0011] As a preferred solution, two straight hair plates are fixedly installed parallel to each other on both sides of the styling surface, and an air outlet is provided on the top surface of the air outlet section. The air outlet is located between the two straight hair plates. The plane where the air outlet is located is lower than the straight hair plates, forming a height difference between the air outlet and the straight hair plates.

[0012] As a preferred solution, a plurality of air guide plates are provided on the air outlet.

[0013] As a preferred solution, the air guide plate is bent and extended from the air outlet into the air outlet section to form an air guide plate end, and the distance between each air guide plate end and the top of the air outlet section gradually increases in the direction away from the transition section.

[0014] As a preferred solution, the transition section and the air outlet section are an integrated structure and can be assembled and installed on one of the arms.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] Please refer to Figures 2 to 10 As shown, it shows the specific structure of the preferred embodiment of the utility model, which is a hair straightener dryer, including a hair straightener unit 10 and a dryer unit 20. This hair styling device has both the functions of a hair straightener and a dryer, and can realize the following multiple modes: one is a hair straightening mode, two is a dryer mode, and three is a hair straightening and blowing mode at the same time. In addition, there are two options of heating and non-heating in the dryer mode.

[0051] The hair straightening unit 10 includes two arms hinged at one end, and two hair straightening plates facing each other are arranged on the shaping surfaces of the two arms. The two arms are called an upper clamping arm 11 and a lower clamping arm 12. The hair straightening plate of the upper clamping arm 11 is an upper hair straightening plate 111, and the hair straightening plate of the lower clamping arm 12 is a lower hair straightening plate 121. When the upper hair straightening plate 111 and the lower hair straightening plate 121 are opened, the hair 100 to be straightened is placed between the upper hair straightening plate 111 and the lower hair straightening plate 121, and then the upper hair straightening plate 111 and the lower hair straightening plate 121 are closed and pulled, and the clamped hair is heated and straightened at the same time by the upper hair straightening plate 111 and the lower hair straightening plate 121, so as to achieve a straightening effect.

[0052] like Figure 3 As shown, the upper clamp arm 11 includes an upper shell 112 and an upper shell cover 113. The upper shell cover 113 is combined with the upper shell 112 by means of snaps, screws or ultrasonic welding, so that the space between the upper shell 112 and the upper shell cover 113 is a hollow structure. Switches and control components such as buttons / knobs / push buttons can be installed in the hollow space. The weight of the entire upper clamp arm 11 is reduced because of its hollow structure rather than a solid structure.

[0053] The lower clamp arm 12 includes a lower shell 122 and a lower shell cover 123. The lower shell cover 123 is combined with the lower shell 122 by snapping, screwing or ultrasonic welding, so that the space between the upper shell cover 113 and the lower shell 122 is a hollow structure. Similarly, the hollow structure can be effectively utilized, which will be explained below.

[0054] Combination Figure 2 and Figure 3 As shown, the upper clamp arm 11 has at least one upper straightening plate 111, and in this embodiment, there are two, which are two straight straightening plates with heating function. The two straightening plates are fixedly installed or elastically installed on the upper clamp arm 11 to form an upper shaping surface. The two upper straightening plates 111 are arranged at a distance, and a avoidance position is formed between the two to make room so that a through-hole avoidance cavity 13 can be opened in the middle position of the upper clamp arm 11. The avoidance cavity 13 is used as a wind nozzle of the hair dryer, and the blowing air can be guided out of the avoidance cavity 13.

[0055] Recombination Figure 2 and Figure 3 As shown, the lower clamp arm 12 has at least one lower straightening plate 121, and in this embodiment, there are two lower straightening plates 121, so as to form a vertically opposite relationship with the upper straightening plate 111. The two lower straightening plates 121 are fixedly installed or elastically installed on the lower clamp arm 12 to form a lower shaping surface. The two lower straightening plates 121 are arranged at a distance, and a avoidance position is formed between the two to make room so that the air outlet 215 of the hair dryer can be set in the middle position of the lower clamp arm 12, realizing a perfect combination of the two functions of the hair dryer and the hair straightening on the same product.

[0056] like Figures 2 to 4 As shown, the air cylinder unit 20 includes an air supply duct 21 located at one arm thereof, which can be arranged at the upper clamping arm 11 or the lower clamping arm 12, and the exchange of positions does not affect normal operation. The air supply duct 21 of this embodiment is only arranged at the lower clamping arm 12, and the air outlet 215 blows toward the avoidance cavity 13 of the upper clamping arm 11, so as to be used as an air cylinder.

[0057] like Figures 4 to 10 As shown, the air supply duct 21 includes a transition section 212, an air outlet section 213, and an air inlet section 211 which are interconnected. The air supply duct 21 also has an air inlet 214 and an air outlet 215. When the wind tube function is used, the outside wind enters the air inlet section 211 from the air inlet 214 in sequence → then enters the transition section 212 → then enters the air outlet section 213 → finally blows out from the air outlet 215.

[0058] like Figure 7 As shown, in one embodiment, the transition section 212, the air outlet section 213, and the air inlet section 211 are on the same arm, and the other arm is provided with a avoidance cavity 13 corresponding to the air outlet 215, and the length and width of the avoidance cavity 13 are larger than those of the air outlet 215. The wind blown out of the air outlet 215 also passes through the wind nozzle shape formed by the avoidance cavity 13, so as to better guide the wind of the hair dryer to blow toward the user's hair. In the lower clamping arm 12, two lower straight hair plates 121 are fixedly installed parallel to each other on both sides of the styling surface, and the air outlet 215 on the top surface of the air outlet section 213 is located between the two lower straight hair plates 121. The plane where the air outlet 215 is located is lower than the two lower straight hair plates 121, and a height difference C is formed between the air outlet 215 and the two lower straight hair plates 121, so that there is enough space to diffuse the airflow 200 ejected at high speed from the air outlet 215, so as to quickly dry the hair.

[0059] The transition section 212 and the air outlet section 213 are an integrated structure, which can be assembled and installed on one of the arms, for example, in the lower clamping arm 12. This integrated structure makes injection molding simpler, with a high yield rate and high production efficiency. In addition, the integrated structure realizes seamless connection between the air supply sections, which is more conducive to reducing the wind noise generated by high-speed airflow.

[0060] like Figure 8 and Fig. 9As shown, the transition section 212 is higher than the outlet section 213, and a height difference A is formed between the two, and the height difference A is connected by a smooth curved surface 216. The connection of the smooth curved surface 216 specifically includes the following characteristics: first, position continuity, which means that the position between the height difference A is continuously extended without any section in the middle; second, tangent continuity, which is a more common continuity method. On the basis of position continuity, the tangent directions at the intersection of the two connected curves are made consistent to generate a smooth effect when the surface transitions; third, curvature continuity, which is based on tangent continuity, and the curvature at the intersection of the two connected curves is consistent, that is, the two curves are tangent, and their tangent radii are consistent, so as to generate a very smooth surface with no obvious corners and smooth transition.

[0061] Specifically, in this embodiment, the smooth curved surface 216 includes a first curved surface 2161 and a second curved surface 2162 which are continuous. The first curved surface 2161 is connected to the transition section 212, and the second curved surface 2162 is connected to the air outlet section 213. The center of the first curved surface 2161 is within the air supply duct 21, and the center of the second curved surface 2162 is outside the air supply duct 21, so as to form a smooth slope descending from the higher transition section 212 to the air outlet section 213, so as to achieve a gradually narrowing and smooth transition connection between the two. Since there is no angle at the connection position that may cause abnormal noise, the wind resistance and noise can be greatly reduced.

[0062] In some embodiments, the bottoms of the transition section 212 and the air outlet section 213 are flush, and the smooth curved surface 216 is provided at the top and / or both sides of the transition section 212 and the air outlet section 213. That is, the transition connection can be made only at the top by the smooth curved surface 216, or only at the sides by the smooth curved surface 216. In this embodiment, the aperture of the air supply duct 21 is reduced by the smooth curved surface 216 at the top and both sides at the same time, so that a certain height difference and two-side avoidance can be made, so that there is enough space to install the straightening plate.

[0063] like Figure 8 As shown, the transition section 212 is equipped with a motor 22 and a heater 23. The motor 22 blows the air from the air inlet section 211 to the heater 23. The heater 23 is powered on when hot air needs to be blown, and does not work when cold air is blown. After being heated by the heater 23, warm / hot air is formed and passes to the air outlet section 213. The air inlet section 211 is enclosed by the lower shell 122 of the arm and the lower shell cover 123. A circuit board 24 is installed in the air inlet section 211. The circuit board 24 is installed in the space of the air inlet section 211. The wind entering from the air inlet 214 continuously dissipates heat for the circuit board 24, ensuring that the circuit board 24 has a long service life.

[0064] The air inlet 214 is arranged beside the two arm hinge positions 14 , and the air inlet 214 is connected to the air inlet section 211 . In this embodiment, the air inlet 214 is a plurality of densely distributed through holes on the air inlet ring 25 .

[0065] like Figures 8 to 10 As shown, the air outlet 215 is provided with a plurality of air guide plates 26, which can evenly blow out the air in the air outlet section 213 to avoid uneven air outlet from the long air outlet 215. In this embodiment, the air guide plate 26 is bent and extended from the air outlet 215 into the air outlet section 213 to form an air guide plate end 261, and the distance between each air guide plate end 261 and the top of the air outlet section 213 gradually increases in the direction away from the transition section 212. Since each air guide plate 26 is an arc-shaped plate, on the one hand, it plays the function of changing the direction of the air outlet, and can blow the horizontal air in the air outlet section 213 vertically out of the air outlet 215. On the other hand, the gradually increasing first air guide plate ends 261 isolate the air inlet section 211 to ensure that the air volume between each two adjacent air guide plates 26 is uniform.

[0066] In summary, the design focus of the present invention is that it mainly adopts a smoothly transitional curved surface connection between the transition section 212 and the air outlet section 213 to form a smooth slope that descends from the higher transition section 212 to the lower air outlet section 213, so as to achieve a gradually narrowing and smooth transition connection between the two. Since there is no angle at the connection position that may cause abnormal noise, the wind resistance and noise can be greatly reduced.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
