DETAILED DESCRIPTION

[0027] The technical solutions in this embodiment of the present application will be described distinctly and completely below in combination with the drawings in this embodiment of the present application. Obviously, the described embodiment is a part of this embodiment of the present application, but not the whole embodiment. Based on this embodiment of the present application, all other embodiments obtained by those ordinary skilled in the art without paying creative labor shall fall within the protection scope of the present application.

[0028] The direction terms mentioned in the present application, such as Up, Down, Front, Back, Left, Right, Inside, Outside and Side, etc., are only the directions referring to the drawings. Therefore, the direction term used is for explaining and understanding the present application, rather than limiting the present application. In addition, in the drawings, structures with similar or identical structures are represented by the same reference signs.

[0029] Referring to FIG. 1, this embodiment of the present application provides an air duct for curling hair, including an inner duct 10 and an outer sleeve 20. The inner duct 10 is provided with an air inlet at the bottom of the inner duct, the interior of the inner duct is hollow, and the side wall of the inner duct 10 is provided with an air outlet part; the outer sleeve 20 is sleeved on the outer side of the inner duct 10, the side wall of the outer sleeve 20 is provided with an air guide part, and the air guide part and the air outlet part are oppositely provided and communicates with each other; where the air outlet direction of the air guide part is deflected in a clockwise direction and/or counterclockwise direction towards the outer sleeve 20.

[0030] Specifically, the air guide part on the outer sleeve 20 is used for guiding the airflow to the side wall of the outer sleeve 20, and flowing along the circumferential direction of the side wall of the outer sleeve 20, that is, the air outlet direction of the air guide part is actually deflected by a certain angle relative to the radial direction of the outer sleeve 20. The airflow flowing along the circumferential direction of the outer sleeve 20 will form a vortex air outlet on the side wall of the outer sleeve 20, thus curling the hair. In this embodiment, the air guide part can adopt unidirectional air outlet and bidirectional air outlet, where the unidirectional air outlet can be that the air outlet direction of the air guide part is deflected in a clockwise direction towards the outer sleeve 20, that is, an airflow flowing in a clockwise direction is formed on the side wall of the outer sleeve 20, so that the hair is curled in a clockwise direction; or the air outlet direction of the air guide part is deflected in a counterclockwise direction towards the outer sleeve 20, that is, an airflow flowing in a counterclockwise direction is formed on the side wall of the outer sleeve 20, so that the hair is curled in a counterclockwise direction. The bidirectional air outlet means that the air guide part has two air outlet directions, and the two air outlet directions are respectively deflected in a clockwise direction and counterclockwise direction towards the outer sleeve 20. It should be noted that the bidirectional air outlet is to choose one direction for air outlet as required, which can be chosen for air outlet either in a clockwise direction or counterclockwise direction, rather than simultaneously chosen for air outlet both in a clockwise direction and counterclockwise direction.

[0031] Through the implementation of this embodiment, an outer sleeve 20 is sleeved on the outer side of the inner duct 10, an air guide part is provided on the outer sleeve 20, the airflow enters the inner duct 10 from the air inlet, and is discharged from the radial direction of the air outlet part of the inner duct 10 to the air guide part, and is deflected in a clockwise direction and/or counterclockwise direction towards the outer sleeve 20 by the air outlet direction of the air guide part, so that the airflow can flow in a clockwise direction or counterclockwise direction along the side wall of the outer sleeve 20, the airflow can have a wall attachment effect on the side wall of the outer sleeve 20, thus achieving the function of hair curling. Compared with the existing structure that uses multiple guide plates, this embodiment uses an outer sleeve 20 to replace the multiple guide plates, and the same air guide function can be achieved only by one component. The present application has the advantages of simple structure, convenient installation and good hair curling effect.

[0032] In this embodiment, the cross section of the outer sleeve 20 is circular or polygonal, that is, the outer sleeve 20 can be a circular duct or a duct with edges. The outer sleeve 20 in this embodiment is a circular duct, and the polygon can be, for example, a triangle, a rectangle, a pentagon or a hexagon, which is not limited here.

[0033] Referring to FIG. 2, FIG. 3, FIG. 5 and FIG. 6, in an embodiment, the air guide part includes a first air outlet slit 21 extending along the axial direction of the outer sleeve 20, where the air outlet direction of the first air outlet slit 21 is deflected in a clockwise direction or counterclockwise direction relative to the outer sleeve 20. Specifically, the first air outlet slit 21 extends from the top of the outer sleeve 20 to the bottom of the outer sleeve 20, multiple first air outlet slits 21 are provided, and the multiple first air outlet slits 21 are uniformly distributed at intervals along the circumferential direction of the outer sleeve 20. Each of the first air outlet slits 21 includes a first slit wall and a second slit wall, the first slit wall and the second slit wall are relatively provided at intervals, the first slit wall and the second slit wall run through the inner and outer sides of the outer sleeve 20, and the first slit wall and the second slit wall can be parallel to each other, close to or far from each other. When the air outlet direction of the air outlet slit is in a clockwise direction, then both the first slit wall and the second slit wall are deflected in a clockwise direction towards the outer sleeve 20; and when the air outlet direction of the air outlet slit is in a counterclockwise direction, then both the first slit wall and the second slit wall are deflected in a counterclockwise direction towards the outer sleeve 20.

[0034] After the airflow is discharged from the radial direction of the air outlet part, it passes between the first slit wall and the second slit, and is discharged in a clockwise direction or counterclockwise direction towards the outer sleeve 20 under the guidance of the first slit wall and the second slit wall. By adopting the structure of the air outlet slit mentioned above, as the air outlet slit extends along the axial direction of the outer sleeve 20, it has a large air outlet area and can curl more hair. Moreover, it has simple air outlet slit structure, making it convenient for the outer sleeve 20 to be integrally styled during manufacturing.

[0035] Furthermore, referring to FIG. 4, in order to achieve bidirectional air outlet, the air guide part further includes a second air outlet slit 22 extending along the axial direction of the outer sleeve 20, the first air outlet slit 21 and the second air outlet slit 22 are provided adjacently along the circumferential direction of the outer sleeve 20, the air outlet direction of the first air outlet slit 21 is deflected in a clockwise direction towards the outer sleeve 20, and the air outlet direction of the second air outlet slit 22 is deflected in a counterclockwise direction towards the outer sleeve 20. Specifically, the first air outlet slit 21 is adjacent to the second air outlet slit 22, the first wall and the second slit wall of the first air outlet slit 21 are deflected in a clockwise direction towards the outer sleeve 20, and the first slit wall and the second slit wall of the second air outlet slit 22 are deflected in a counterclockwise direction towards the outer sleeve 20. By providing two air outlet slits to form circumferential airflow in different directions, the hair can be curled in different directions, so as to meet the requirements of various styles.

When the user rotates the rotating member 30, it drives the inner duct 10 to rotate relative to the outer sleeve, thus changing the position of the air outlet part, so that the air outlet part can be opposite to the first air outlet slit 21 or the second air outlet slit 22, that is, the air outlet part can switch back and forth between the first air outlet slit 21 and the second air outlet slit 22, thus changing the flow direction of the airflow. When the air outlet part is rotated to be opposite to the first air outlet slit 21, the second air outlet slit 22 is covered by the side wall of the inner duct 10, and the airflow flows in a clockwise direction towards the outer sleeve 20; and when the air outlet part is rotated to be opposite to the second air outlet slit 22, the first air outlet slit 21 is covered by the air outlet slit of the inner duct 10, and the airflow flows in a counterclockwise direction towards the outer sleeve. Therefore, the air outlet direction can be switched by rotating the rotating member 30, and the flow direction of the airflow can be changed to adapt to more styling scenarios.

[0037] In addition, it should be noted that for the first air outlet slit 21 with unidirectional air outlet, the rotating member 30 is rotated so that the air outlet part is opposite to the first air outlet slit 21, thus opening the first air outlet slit 21; or the air outlet part is opposite to the inner wall surface of the outer sleeve 20, thus closing the first air outlet slit 21.

[0038] In an embodiment, referring to FIG. 5 and FIG. 6, the first air outlet slit 21 and the second air outlet slit 22 are both provided with multiple partition bars 24, and the multiple partition bars 24 are provided at intervals along the axial direction of the outer sleeve 20. Specifically, the partition bar 24 separates the slender first air outlet slit 21 and the second air outlet slit 22, the first air outlet slit 21 is divided into multiple sub-air outlet slits, making the air force in each of the sub-air outlet slits more concentrated and avoiding turbulence.
