[0033] The utility model provides a hair curling accessory which is used for a hair curling device.

[0034] In the embodiment of the present utility model, Figures 1 to 8 As shown, the curling accessory comprises a fixing sleeve 20, a barrel body 10 and a front cover 30, wherein the fixing sleeve 20 is provided with an air inlet channel 21; the barrel body 10 is an integrated structure and is provided with a plurality of air guide structures 11, each of the air guide structures 11 comprises a first air guide portion 111 and a second air guide portion 112 which are spaced apart and extend along the length direction of the barrel body 10, so as to form an air outlet 114 between the first air guide portion 111 and the second air guide portion 112, and the first air guide portion 111 and the second air guide portion 112 are sequentially arranged along the first circumferential direction of the barrel body 10 ... The air guide portion 111 is protruded relative to the second air guide portion 112. In the first circumferential direction, the spacing between the first air guide portion 111 and the second air guide portion 112 is greater than or equal to 0 mm. The first air guide portion 111 and the second air guide portion 112 are provided with an air guide surface 113 on the side facing each other. Each air guide surface 113 extends obliquely along the first circumferential direction. The rear end of the barrel body 10 is connected to the fixed sleeve 20, and the inner cavity of the barrel body 10 is connected to the air inlet channel 21; the front cover 30 is installed at the front end of the barrel body 10 to block the front end opening of the barrel body 10.

[0035] Specifically, the first circumferential direction may be a counterclockwise direction (refer to Figure 5 C1 in the figure), or clockwise (refer to Figure 8 In the same state, for example, the state in which the front cover 30 of the curling accessory points to the direction of the fixing sleeve 20 and is projected on a virtual projection surface.

[0036] All the air guide surfaces 113 extend obliquely along the first circumferential direction in the direction close to the outer peripheral surface of the barrel 10, so that the air outlet direction of each air outlet 114 is set at an acute angle with the outer peripheral surface of the barrel 10, so that when the airflow in the inner cavity of the barrel 10 flows out from the air outlet 114, the airflow can flow along the outer peripheral surface of the barrel 10 under the action of the Coanda effect, and when multiple air outlets 114 discharge air at the same time, the outlet airflow can flow around the outer peripheral surface of the barrel 10. In this way, when the hair is close to the barrel 10, the hair can be rolled around the barrel 10 under the drive of the airflow. When the outlet airflow is hot air, the hair can be heated by the hot air to achieve the effect of curling. In this way, automatic curling can be achieved, which is convenient for users to perform curling operations.

[0037] In the first circumferential direction, when the spacing between the first air guide portion 111 and the second air guide portion 112 is greater than or equal to 0mm, that is, there is no overlapping part between the first air guide portion 111 and the second air guide portion 112 in the radial direction of the barrel 10, so when forming the barrel 10, the profile can be made first, and then the guide surface and the air outlet 114 can be CNC-processed on the surface of the profile. Since the spacing between the first air guide portion 111 and the second air guide portion 112 is greater than or equal to 0mm, the difficulty of CNC processing can be reduced. Optionally, the air guide surface 113 on the first air guide portion 111 extends from the outer side surface of the first air guide surface 113 to the inner side surface, so that the air flow can be better inclined and guided along the first circumferential direction. Optionally, the barrel 10 is a straight tube, a tapered tube or other irregular shapes (for example, one section is a straight tube and the other section is a tapered tube).

[0038] The technical solution of the utility model is to set the barrel 10 as an integrated structure, and to form a plurality of first air guides 111 and second air guides 112 on the barrel 10, which are spaced apart and extend along the length direction of the barrel 10, so that an air outlet 114 is formed between the first air guide 111 and the second air guide 112, and in the first circumferential direction, the spacing between the first air guide 111 and the second air guide 112 is greater than or equal to 0 mm. Compared with the assembled barrel 10 structure, the number of parts of the barrel 10 can be reduced, the structure of the barrel 10 can be simplified, and it is convenient to assemble in the production process. Compared with the method in which the first air guide 111 and the second air guide 112 overlap in the radial direction of the barrel 10 to form the air outlet 114, it is convenient to process and form the air guide surface 113 and the air outlet 114 on the barrel 10, and the difficulty of forming can be reduced. Moreover, an air guiding surface 113 is provided on the side where the first air guiding portion 111 and the second air guiding portion 112 face each other, so that each air guiding surface 113 extends obliquely along the first circumferential direction, so that the outlet direction of the air flow can extend roughly along the tangential direction of the cylinder body 10, so that the air flow can flow along the outer circumferential surface of the cylinder body 10.

[0039] In some embodiments, the number of air guide structures 11 (i.e., the number of air outlets 114) is 5, 6, 7 or 8; such a configuration can not only better form a winding airflow around the outer periphery of the barrel 10, but also avoid the situation where too many air outlets 114 lead to a complex structure and excessively high production costs.

[0040] The material of the barrel 10 can be multiple. For example, in some embodiments, the material of the barrel 10 is metal, such as the material of the barrel 10 is aluminum alloy, zinc alloy, etc. By adopting metal to make the barrel 10, the barrel 10 structural strength can be made high and the service life is long. In the present embodiment, the material of the barrel 10 is aluminum alloy, which can be convenient for the barrel 10 molding and help reduce production costs. Of course, in other embodiments, the material of the barrel 10 can also be engineering plastics, such as PA6+30% GF material.

[0041] In some embodiments, the wind guiding surface 113 of the first wind guiding portion 111 is arranged in parallel with the wind guiding surface 113 of the second wind guiding portion 112. Such an arrangement can facilitate processing and forming of the two wind guiding surfaces 113 while achieving better wind guiding.

[0042] In some embodiments, a support rib 12 is provided in the air outlet 114, the support rib 12 connects the first air guide portion 111 and the second air guide portion 112, and is located between the two ends of the second air guide portion 112. Specifically, the number of the support ribs 12 may be one or more, and the support ribs 12 are connected to the two air guide surfaces 113 as a whole. By providing the support ribs 12, the structural strength of the air outlet 114 can be improved, and the risk of deformation of the first air guide portion 111 and the second air guide portion 112 can be reduced.

[0043] In some embodiments, the width of the support rib 12 gradually decreases along the air outlet direction of the air outlet 114. This arrangement can reduce the influence of the support rib 12 on the air outlet airflow, that is, avoid the formation of turbulent airflow outside the support rib 12, so that the air outlet airflow at each position of the air outlet 114 (in the length direction of the barrel 10) is more uniform, thereby improving the airflow curling effect.

[0044] The utility model also proposes a curling device (not shown), which includes a housing, a fan assembly, a heating assembly and a curling accessory. The specific structure of the curling accessory refers to the above embodiment. Since the curling device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, an air duct is provided in the housing, and the curling accessory is connected to one end of the housing through a fixed sleeve 20. The air inlet channel 21 of the fixed sleeve 20 is connected to the air duct. The heating assembly and the fan assembly are both provided in the air duct, and the heating assembly is located between the fan assembly and the air inlet channel 21. The housing is also provided with an air inlet. Optionally, the air inlet is provided at one end of the housing away from the fixed sleeve 20. The heating assembly can be a conventional heating device such as an electric heating wire. Among them, the housing can be straight, "7"-shaped or "T"-shaped, etc.

[0045] In some embodiments, the fixing sleeve 20 is detachably connected to the housing, that is, the curling accessory can be detachably mounted on one end of the housing through the fixing sleeve 20, so that the curling accessory can be easily replaced, for example, by equipping a plurality of curling accessories of different sizes, so that the user can choose to use according to the needs.

[0046] The fixing sleeve 20 can be detachably connected to the outer shell in a variety of ways. For example, in one embodiment, the fixing sleeve 20 is snap-fitted to the outer shell; in another embodiment, the fixing sleeve 20 and the outer shell are connected via a threaded structure (the fixing sleeve 20 is provided with an external thread, and the outer shell is correspondingly provided with a threaded hole; or the air inlet channel 21 is provided with an internal thread, and the outer shell is correspondingly provided with an external threaded portion).

[0047] In some embodiments, the hair curling device comprises a plurality of (at least two) hair curling accessories, wherein the plurality of hair curling accessories are selectively mounted on the housing, wherein the first circumferential directions of at least two of the hair curling accessories are opposite (refer to Figure 5 and Figure 8 ).
