Description

Technical Field

[0001] This invention belongs to the field of hair styling tool technology, and particularly relates to a hair clip air duct structure and its hair straightener. Background Technology

[0002] A hair straightener, also known as an electric straightener, is a hair styling tool used to quickly straighten hair. Most traditional hair straighteners simply use a heating plate to clamp and heat the hair, while a few also have a blower function, which dries the hair while straightening it.

[0003] Most hair straighteners on the market typically have their airflow direction perpendicular to the plates. When using a hair straightener, hair is placed between the plates and heated to straighten it. However, the airflow from a hair straightener tends to blow hair out of the styling area, making it difficult to achieve a straightened look or resulting in extremely low efficiency. Users need to repeat the straightening process multiple times, leading to a poor user experience.

[0004] Therefore, in view of the above-mentioned technical problems, the present invention provides a hair clip air duct structure applied to a hair straightener. By guiding the airflow from the outlet to always be directed towards the air inlet side through the diffuser, the present invention can prevent hair from being blown out of the styling area, ensure that the straightening styling is completed smoothly, improve the straightening efficiency and improve the user experience, thereby solving one or more of the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, the present invention provides a hairpin air duct structure. Includes articulated air guide connectors and hair clips; The hair clip has an internal air guide cavity, a styling surface, and an air outlet. The air outlet is connected to the air guide cavity, and the opening of the air outlet faces the styling surface. The opening of the air outlet is also inclined towards the air inlet side of the air guide cavity. The air outlet guides the air out to blow towards the styling area of ​​the clip panel and the air inlet side.

[0006] Optionally, in some technical solutions, a guide plate is provided on the side of the air guide cavity near the air outlet. The guide plate is arranged at a non-perpendicular angle with the longitudinal axis of the air guide cavity, and the guide plate guides the air outlet to blow towards the air inlet side.

[0007] Optionally, in some technical solutions, the guide plate is composed of several baffles, which are distributed along the length axis of the air guide cavity, and the several baffles divide the air outlet in a segmented manner.

[0008] Optionally, in some technical solutions, the distance between the partitions and the longitudinal axis of the air guide cavity gradually decreases from the air inlet of the air guide cavity.

[0009] Optionally, in some technical solutions, the angle A between the partition and the longitudinal axis of the air guide cavity is less than 89 degrees.

[0010] Optionally, in some technical solutions, the air guide connector is provided with a first air outlet and a second air outlet, the first air outlet and the second air outlet being respectively connected to the air guide cavities of the two hair clips.

[0011] Optionally, in some technical solutions, a guide plate is provided on the inner side of the shaped surface near the air outlet. The guide plate is arranged at a non-perpendicular angle with the length axis of the air guide cavity, and the guide plate guides the air outlet to blow towards the air inlet side.

[0012] Optionally, in some technical solutions, the outer side of the air outlet is formed as a first calibration plane, and the upper plane of the guide plate is parallel to or lower than the first calibration plane.

[0013] Optionally, in some technical solutions, one end of the guide plate extends along the longitudinal axis of the air guide cavity.

[0014] In addition, the present invention also provides a hair straightener that applies the hair clip airflow structure described above.

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] In the description of this invention, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] In the description of this invention, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0023] like Figure 1 As shown, in the prior art, the hot air from the hair straightener blows out from the rear end of the straightener. When the user is straightening their hair, the air blown by the hair straightener blows the hair towards the front end of the hair clip 2. In this case, only a portion of the hair can fall on the effective working area of ​​the straightener, namely the styling area of ​​the styling surface 6, for straightening, while a small portion of the hair cannot fall on the styling surface 6 for straightening. This results in low straightening efficiency of the straightener, and the user needs to repeat the straightening operation multiple times to achieve the desired straightening effect. Furthermore, during the use of the straightener, some hair is blown directly out from the front end of the straightener, making it difficult to hold the hair in place.

[0024] Example 1 like Figure 2-8As shown, Embodiment 1 of the present invention provides a hair clip air duct structure, including an air guide connector 1 and two hair clips 2. The two hair clips 2 are hinged to the air guide connector 1. The air guide connector 1 is provided with a first air outlet 3 and a second air outlet 4, which are respectively connected to the two hair clips 2. The interior of the hair clip 2 is formed as an air guide cavity 5, and the first air outlet 3 and the second air outlet 4 are respectively connected to the air guide cavity 5 of the two hair clips 2. One side of the hair clip 2 is provided with a styling surface 6 for styling. One side of the styling surface 6 is provided with a clamping member 7. An air outlet 8 is provided inside the clamping member 7. The opening of the air outlet 8 faces the styling area of ​​the clamping panel 6 and is connected to the air guide cavity 5. The opening of the air outlet 8 is also inclined to the air inlet 10 side of the air guide cavity 5, that is, the opening of the air outlet 8 has a component facing the air inlet 10 side. When air is emitted from the air outlet 8, one component perpendicular to the styling surface 6 blows towards the styling area, while the other component parallel to the styling surface 6 blows towards the air inlet 10. This allows the air outlet 8 to guide the airflow towards both the styling area of ​​the styling surface 6 and the air inlet 10, concentrating the hair within the styling area of ​​the styling surface 6 and drawing it towards the air inlet end of the hair clip 2, preventing it from being blown out of the clip's front end. This hair clip airflow structure, applied to the straightener, by tilting the air outlet 8 towards the air inlet 10, controls the airflow to always be directed towards the styling area of ​​the styling surface 6 and the air inlet 10. This prevents hair from being blown out of the styling area, ensuring successful straightening, improving straightening efficiency, and enhancing the user experience.

[0025] Specifically, the front end of the air guide connector 1 is formed as a mounting base 11. The upper and lower hair clips 2 are rotatably hinged by a pin 12. The upper and lower hair clips 2 may have the same air duct structure. The front end face of the mounting base 11 is divided into a first air outlet 3 and a second air outlet 4. The upper hair clip 2 is installed corresponding to the first air outlet 3, and the lower hair clip 2 is installed corresponding to the second air outlet 4. More specifically, the hair clip 2 is formed as a cavity structure. The internal cavity of the hair clip 2 forms an air guide cavity 5. The rear opening of the air guide cavity 5 forms an air inlet 10, and the front end of the air guide cavity 5 is closed. A styling surface 6 is installed on the front side of the hair clip 2. The styling surface 6 may be a heating plate surface. The front of the styling surface 6 is the styling area of ​​the hair straightener. The styling surface 6 is used to heat and style the hair, making it easier to achieve a straight hair effect after heating. A clamping member 7 is longitudinally arranged along the outer side of the styling surface 6. The clamping member 7 is compressibly mounted on the upper hair clamping plate 2 with the spring 13, and can be fixedly mounted on the lower hair clamping plate 2. Thus, when the hair straightener is operated, the upper hair clamping plate 2 can open at a certain angle to allow the user to put the hair into the straightener. Then, the upper hair clamping plate 2 presses down on the lower hair clamping plate 2, and the two clamping members 7 on the upper and lower hair clamping plates 2 can clamp the hair. Since the upper hair clamping plate 2 is equipped with a spring 13, the upper clamping member 7 can be compressed. After the spring 13 is compressed on the upper clamping member 7, its reaction force provides sufficient pressure to clamp the hair, and can also pull the straightener to complete the straightening operation.

[0026] Furthermore, in this embodiment, a plurality of air outlets 8 are longitudinally arranged on the inner side of the clamping member 7. The openings of the air outlets 8 face the styling area of ​​the clamping panel 6, and the openings of the air outlets 8 are also inclined towards the air inlet 10. Specifically, the air outlets 8 have an angle of 0-90 degrees in the direction perpendicular to the styling surface and an angle of 0-90 degrees in the direction parallel to the styling surface, which is the plane of the clamping panel 6. The air outlets 8 are connected to the air guide cavity 5 so that the hot air in the air guide cavity 5 can be blown out from the air outlets 8. The air outlets 8 are used to blow out hot air to heat the hair for straightening and styling. The air outlets 8 can also be a single elongated air outlet 8. More specifically, in this embodiment, a guide plate 9 is arranged on the side of the air guide cavity 5 near the air outlets 8. The guide plate 9 is arranged at a non-perpendicular angle to the length axis L of the air guide cavity 5. The guide plate 9 guides the air outlets 8 to the air inlet 10 of the air guide cavity 5. The air guide plate 9 can be composed of multiple partitions 14 or a single partition 14. The air guide plate 9 is integrally formed with the outer shell of the hair straightener 2. Each partition 14 of the air guide plate 9 is not perpendicular to the longitudinal axis L of the air guide cavity 5, and the upper end of the air guide plate 9 faces the air inlet 10 of the air guide cavity 5. This allows the air guide plate 9 to direct the airflow from the air outlet 8 towards the air inlet 10 of the air guide cavity 5, achieving a reverse airflow effect. This allows the airflow from the air outlet 8 to blow the hair towards the back of the straightener, concentrating the hair within the styling area of ​​the styling surface 6 for straightening. This prevents the airflow from the air outlet 8 from blowing the hair out of the front of the hair straightener 2, ensuring successful straightening and improving efficiency. In this case, the number of straightened styles achieved by the user in a single straightening action is effectively increased, reducing the number of repetitive straightening operations and improving the user's straightening experience. Furthermore, in this embodiment, the guide plate 9 is composed of several partitions 14, which are evenly distributed along the length axis L of the air guide cavity 5. The partitions 14 divide the air outlet 8 into segments. Specifically, the guide plate 9 is composed of four partitions 14, which are arranged in a fan shape. The four partitions 14 are evenly distributed along the length axis L of the air guide cavity 5. The four partitions 14 are located on one side of the air outlet 8 in the air guide cavity 5, and the upper part of each partition 14 is close to or tightly attached to the lower part of the shaped surface 6. Each partition 14 corresponds to one of the air outlets 8, so that the partitions 14 can achieve segmented air diversion of the air outlet 8. It should be noted that the air from the hair straightener enters the air guide cavity 5 from the air inlet 10 through the first air outlet 3 or the second air outlet 4. The side of the air guide cavity 5 with the baffle 14 plays a guiding role, and the baffle 14 divides the air into sections to the air outlet 8. The side without the baffle 14 is a larger volume air channel, which can accommodate the air volume and avoid the formation of vortices when blowing air.

[0027] Furthermore, in this embodiment, as Figure 5As shown, the distance between the partitions 14 and the longitudinal axis L of the air guide cavity 5 gradually decreases from the air inlet 10 of the air guide cavity 5. Specifically, the four partitions 14 are arranged in a progressive manner, that is, the distance C between the bottom end of the four partitions 14 and the longitudinal axis L of the air guide cavity 5 gradually decreases from the air inlet 10 of the air guide cavity 5 to the closed end of the air guide cavity 5, and one end of each partition 14 extends to the longitudinal axis L of the air guide cavity 5. Since the airflow of the straightener is provided by the air guide connector 1, when the airflow blows into the air guide cavity 5, the air pressure at the rear end of the air guide cavity 5 will be higher than the air pressure at the front end of the air guide cavity 5, that is, the air pressure at the air inlet 10 of the air guide cavity 5 is higher than the air pressure at the closed end of the air guide cavity 5. The progressive arrangement of each partition 14 can balance the airflow at each air outlet 8 and improve the straightening effect of the straightener. It should be noted that the area of ​​each partition 14 can be increased sequentially to achieve the progressive arrangement effect.

[0028] Furthermore, in this embodiment, the angle A between the guide plate 9 and the longitudinal axis L of the air guide cavity 5 is less than 89 degrees. Specifically, in order to ensure that the air outlet 8 blows the air to the side of the air inlet 10 of the air guide cavity 5, the plane on which each partition 14 is located is set so that the angle A between it and the longitudinal axis L of the air guide cavity 5 is less than 89 degrees, that is, the partition 14 and the axis L form an acute angle. The size of the acute angle can be specifically set according to product requirements. As long as the two are not perpendicular, the air outlet can have a component pointing towards the air inlet 10.

[0029] Example 2 like Figure 9-11As shown, Embodiment 2 of the present invention provides a hair clip air duct structure, including an air guide connector 1 and two hair clips 2. The two hair clips 2 are hinged to the air guide connector 1. The air guide connector 1 is provided with a first air outlet 3 and a second air outlet 4, which are respectively connected to the two hair clips 2. The interior of the hair clip 2 is formed as an air guide cavity 5, and the first air outlet 3 and the second air outlet 4 are respectively connected to the air guide cavity 5 of the two hair clips 2. One side of the hair clip 2 is provided with a styling surface 6 for forming a style. One side of the styling surface 6 is provided with a clamping member 7. An air outlet 8 is provided inside the clamping member 7. The opening of the air outlet 8 faces the styling area of ​​the clamping panel 6 and is connected to the air guide cavity 5. The opening of the air outlet 8 is also inclined to the air inlet 10 side of the air guide cavity 5, that is, the opening of the air outlet 8 has a component facing the air inlet 10 side. When air is emitted from the air outlet 8, one component perpendicular to the styling surface 6 blows towards the styling area, while the other component parallel to the styling surface 6 blows towards the air inlet 10. This allows the air outlet 8 to guide the airflow towards both the styling area of ​​the styling surface 6 and the air inlet 10, concentrating the hair within the styling area of ​​the styling surface 6 and drawing it towards the air inlet end of the hair clip 2, preventing it from being blown out of the clip's front end. This hair clip airflow structure, applied to the straightener, by tilting the air outlet 8 towards the air inlet 10, controls the airflow to always be directed towards the styling area of ​​the styling surface 6 and the air inlet 10. This prevents hair from being blown out of the styling area, ensuring successful straightening, improving straightening efficiency, and enhancing the user experience.

[0030] Specifically, the main difference between this embodiment two and embodiment one lies in the different positions of the guide plate 9. In this embodiment two, the guide plate 9 is positioned on the styling surface 6 and close to the inner side of the air outlet 8. More specifically, the interior of the hair clip 2 is formed as an air guide cavity 5, the rear end of the air guide cavity 5 is formed as an air inlet 10, and the front end of the air guide cavity 5 is closed. The two hair clips 2 are rotatably hinged to the air guide side connector via a pin 12. The front end of the air guide connector 1 is formed as a mounting base 11, which is divided into a first air outlet 3 and a second air outlet 4. The upper hair clip 2 is installed corresponding to the first air outlet 3, and the lower hair clip 2 is installed corresponding to the second air outlet 4. The first air outlet 3 connects to the air guide cavity 5 of the upper hair clip 2, and the second air outlet 4 connects to the air guide cavity 5 of the lower hair clip 2. A styling surface 6 is installed on the front side of the hair clip 2. The styling surface 6 is a heating panel used to heat the hair. A clamping member 7 is installed on the outer side of the styling surface 6 on the hair clip 2. The clamping member 7 is used to clamp the hair. Multiple air outlets 8 are provided on the outer side of the styling surface 6 and on the inner side of the clamping member 7. The air outlets 8 are connected to the air guide cavity 5. The air supplied to the air guide cavity 5 from the first air outlet 3 or the second air outlet 4 can be blown out from the air outlets 8.

[0031] Furthermore, in this embodiment, a guide plate 9 is provided on the inner side of the shaped surface 6 near the air outlet 8. The guide plate 9 is set at a non-perpendicular angle to the longitudinal axis L of the air guide cavity 5, and the guide plate 9 guides the air outlet 8 toward the air inlet 10 of the air guide cavity 5. Specifically, the guide plate 9 is set on the side of the shaped surface 6 near the air outlet 8 and located inside the air outlet 8. The guide plate 9 can be composed of multiple partitions 14, with each air outlet 8 corresponding to each partition 14. The plane of the multiple partitions 14 is inclined toward the air inlet 10 of the air guide cavity 5, that is, the guide plate 9 is set at a non-perpendicular angle E to the longitudinal axis L of the air guide cavity 5, and the guide plate 9 guides the air outlet 8 toward the air inlet 10 of the air guide cavity 5. When the hair straightener is used for straightening, the air in the air guide cavity 5 is blown out from the air outlet 8. Under the guidance of the guide plate 9, the air is blown to the side of the air inlet 10 of the air guide cavity 5, so that the air can be concentrated at the rear end of the hair straightener, thus preventing the hair from being blown to the front end of the hair straightener and away from the working area of ​​the styling surface 6.

[0032] Furthermore, in this embodiment, the angle E between the guide plate 9 and the longitudinal axis L of the air guide cavity 5 is less than 89 degrees. Specifically, in order to ensure that the air outlet 8 blows the air to the side of the air inlet 10 of the air guide cavity 5, the plane on which each partition 14 is located is set so that the angle E between it and the longitudinal axis L of the air guide cavity 5 is less than 89 degrees, that is, the partition 14 and the axis L form an acute angle. The size of the acute angle can be specifically set according to product requirements. As long as the two are not perpendicular, the air outlet can have a component pointing towards the air inlet 10.

[0033] Furthermore, in this embodiment, the outer side of the air outlet 8 is formed as a first calibration plane 15, and the upper plane of the guide plate 9 is parallel to or lower than the first calibration plane 15. Specifically, in practical applications, if the height of the partitions 14 of the two hair clips 2 is too high, when the two hair clips 2 are in a clamping state, the guide plates 9 on the two hair clips 2 will touch each other, causing the clamping member 7 to fail to clamp the hair. Therefore, in order to prevent the height of the partitions 14 from affecting the clamping effect of the hair clips 2, the hair clips 2 are formed as a first calibration plane 15 on the outer side of the air outlet 8. The first calibration plane 15 is formed on the shell of the hair clips 2, and the height of the multiple partitions 14 is not higher than the first calibration plane 15, that is, the upper plane of the guide plate 9 is parallel to or lower than the first calibration plane 15. Figure 11 There is a gap F between the top surface of the partition plate 14 and the first calibration plane 15, and the gap F can approach zero.

[0034] Furthermore, in this embodiment, one end of the guide plate 9 extends along the longitudinal axis L of the airflow cavity 5. Specifically, in order to better guide the airflow from the air outlet 8 towards the styling surface 6, thereby improving the straightening effect of the hair straightener, one end of each partition 14 is located outside the air outlet 8 and connected to the side of the first calibration plane 15, and the other end of each partition 14 extends along the longitudinal axis L of the airflow cavity 5, that is, one end of the guide plate 9 extends along the longitudinal axis L of the airflow cavity 5, such as... Figure 10 The extended distance shown is G. When the hair straightener performs a straightening operation, the airflow from the air outlet 8 is guided by the guide plate 9 to the center of the styling surface 6, making the hair more evenly heated and thus improving the straightening effect. Preferably, the guide plate 9 is integrally formed with the styling surface 6, that is, multiple partitions 14 are directly formed on the styling surface 6, which can effectively reduce production costs.

[0035] Example 3 like Figure 12 As shown, Embodiment 3 of the present invention provides a hair straightener. The hair straightener utilizes the hair clip air duct structure of the above embodiments. The opening of the air outlet 8 faces the styling area of ​​the clamping plate 6, and the opening of the air outlet 8 is also inclined towards the air inlet 10 side of the air guide cavity 5. Therefore, the air outlet 8 can guide the airflow towards the styling area of ​​the styling surface 6 and the air inlet 10 side, thereby concentrating the hair in the styling area of ​​the styling surface 6 and drawing it towards the air inlet end of the hair clip 2, preventing it from being blown out of the front end of the hair clip 2. The guide plate 9 can be disposed inside the air guide cavity 5 near the air outlet 8 or on the styling surface 6 near the inner side of the air outlet 8. The guide plate 9 is set at a non-perpendicular angle to the longitudinal axis L of the air guide cavity 5. The hair straightener, through the air outlet 8 and the guide plate 9, guides the airflow to always face the styling area of ​​the styling surface 6 and the air inlet 10 side of the air guide cavity 5, preventing hair from being blown out of the styling area, ensuring smooth straightening, reducing the number of repetitions of the straightening operation, improving straightening efficiency, and enhancing the user experience.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
