The air outlet duct 1 has a frame 3 inside, and several air outlets 5 are opened on the side wall of the air outlet duct 1. Several guide vanes 6 are provided on the side of the air outlet duct 1 corresponding to the positions of the air outlets 5. The guide vanes 6 are inserted into the frame 3. When the guide vanes 6 are installed, they are inserted along the axial direction of the frame 3. Compared with the traditional installation method of fastening the guide vanes 6 to the air outlet duct, the installation efficiency of the guide vanes 6 is improved. In addition, the end cap assembly 2 is anti-detached from the end of the guide vanes 6. When the end cap assembly 2 is placed on the air outlet duct 1, the outer edge of the end cap assembly 2 restricts the radial displacement of the guide vanes 6 and prevents the guide vanes 6 from falling off.

[0041] like Figure 3 As shown, the air outlet duct 1 is integrally formed with a positioning part 4, and the frame 3 includes a first mounting plate 31 and a second mounting plate 32. The first mounting plate 31 and the positioning part 4 are positioned and matched. In addition, the first mounting plate 31 and the second mounting plate 32 are arranged alternately. When the guide vane 6 is installed, it is inserted into the second mounting plate 32 along the axial direction of the air outlet duct 1. At the same time, when the guide vane 6 is installed, the positioning part 4 on both sides assists in positioning and guiding, which further improves the installation efficiency of the guide vane 6 and realizes the rapid installation of the air outlet duct 1. Moreover, a large space is reserved between the first mounting plate 31 and the second mounting plate 32 of the frame 3 to facilitate the air outlet duct 1 to discharge air.

[0042] Preferably, the guide vane 6 has a T-shaped slot 61 on the side near the frame 3, and the end of the second mounting plate 32 has a corresponding T-shaped connecting part 33. When the guide vane 6 is inserted, the bottom end of the T-shaped slot 61 is inserted axially from the top end of the connecting part 33. The T-shaped slot 61 and the connecting part 33 are positioned and inserted together, so that the guide vane 6 is more accurately guided and positioned during installation and more secure after installation.

[0043] In addition, in this embodiment, the guide vane 6 has a T-shaped slot 61, and the frame 3 has a corresponding connecting part 33. In other embodiments, the slot cross section on the guide vane 6 can also be Y-shaped, cross-shaped or other shapes, and Y-shaped or cross-shaped blocks are set on the mounting plate accordingly, which also have the effect of positioning guidance and firm installation.

[0044] like Figure 2 As shown, the guide vane 6 has a bent portion 62 at its end, and positioning grooves 621 are provided on both sides of the bent portion 62. The upper end of the positioning portion 4 is provided with a positioning protrusion 41. After the guide vane 6 is inserted, the positioning protrusion 41 on the positioning portion 4 is inserted into the positioning groove 621, so that the guide vane 6 and the positioning portion 4 form an integral whole, further restricting the radial displacement of the guide vane 6 and improving the installation stability of the guide vane 6.

[0045] like Figure 2 As shown, the end cap assembly 2 and the positioning part 4 on the air outlet 1 are engaged by a buckle 42 and a slot 43. In this embodiment, the positioning part 4 has buckles 42 arranged in a ring at intervals on the side near the end cap assembly 2, and the end cap assembly 2 has a corresponding slot 43 on the side near the air outlet 1. When the end cap assembly 2 is installed, pressing down on the end cap assembly 2 causes the buckles 42 to engage with the slot 43, improving the overall integrity of the curling iron. When the end cap assembly 2 is disassembled, external force is applied to disengage the buckles 42 from the slot 43, facilitating the disassembly and installation of the end cap assembly 2. In other embodiments, by setting a slot 43 on the positioning part 4 and a buckle 42 on the end cap assembly 2, or by simultaneously setting a slot 43 and a buckle 42 on the positioning part 4 and correspondingly setting a buckle 42 and a slot 43 on the end cap assembly 2, the same effect of improving the ease of installation and disassembly of the end cap assembly 2 can be achieved.

[0046] like Figure 2 , 6 As shown, the inner side of the guide vane 6 is provided with air guide ribs 63, and the air guide ribs 63 are arranged at intervals. After the guide vane 6 is installed, the air guide ribs 63 abut against the positioning part 4, and an air guide channel 64 is formed between adjacent air guide ribs 63. When the curling iron is used, the air comes out from the air outlet 5 and is guided and delivered through the air guide channel 64 to curl and shape the hair on the outer surface of the air outlet 1.

[0047] like Figure 2 , 7 As shown in Figure 8, the end cap assembly 2 includes an outer end cap 21 and an inner end cap 22 disposed inside the outer end cap 21. The inner end cap 22 includes a base 221 and a cylindrical portion 222 fixed on the base 221. A first positioning structure 7 is provided between the base 221 and the air outlet duct 1 so that the base 221 of the inner end cap 22 is positioned and installed at the end of the air outlet duct 1 through the first positioning structure 7. A second positioning structure 8 is provided between the outer end cap 21 and the cylindrical portion 222 so that the outer end cap 21 is positioned and installed on the cylindrical portion 222 of the inner end cap 22 through the second positioning structure 8. This realizes the positioning and installation of the outer end cap 21 and the inner end cap 22, and improves the installation stability between the air outlet duct 1, the inner end cap 22 and the outer end cap 21.

[0048] Furthermore, the inner end cover 22 also includes a stop protrusion 223. In this embodiment, multiple stop protrusions 223 are arranged in a ring at intervals on the outer edge of the base 221 of the inner end cover 22. When the inner end cover 22 is placed on the air outlet duct 1, the stop protrusions 223 are attached to the guide vane 6. The guide vane 6 and the stop protrusions 223 are axially stopped, which restricts the axial displacement of the guide vane 6 and improves the installation stability of the guide vane 6 after the end cover assembly 2 is closed.

[0049] like Figure 7As shown, in this embodiment, a positioning protrusion 71 is provided at the upper end of the air outlet duct 1, and a first positioning groove 72 is provided at the corresponding position of the base 221 of the inner end cover 22. When the inner end cover 22 is installed, the first positioning groove 72 and the positioning protrusion 71 are positioned and engaged. At the same time, the positioning protrusion 71 prevents the inner end cover 22 from rotating relative to the air outlet duct 1 after installation. In other embodiments, the first positioning groove 72 is provided at the upper end of the air outlet duct 1, and the positioning protrusion 71 is provided on the base 221 of the inner end cover 22, which has the same effect as the first positioning structure 7 in this embodiment. In addition, by increasing the number of positioning protrusions 71 and first positioning grooves 72 in pairs, the installation stability of the inner end cover 22 is further improved.

[0050] like Figure 8 As shown, in this embodiment, the inner side of the outer end cover 21 is provided with a positioning rib 81, and the cylindrical part 222 of the inner end cover 22 is provided with a corresponding second positioning groove 82. When the outer end cover 21 is placed on the inner end cover 22, the positioning rib 81 is positioned and inserted into the second positioning groove 82, while preventing the outer end cover 21 from rotating relative to the inner end cover 22, which facilitates the positioning and installation of the outer end cover 21. In addition, similar to the first positioning structure 7, by increasing the number of positioning ribs 81 and the second positioning groove 82, the installation stability of the inner end cover 22 is further improved.

[0051] The basic working principle of this utility model is as follows: The frame 3 and the guide vane 6 are inserted together. When installing the guide vane 6, the guide vane 6 is inserted from the end of the frame 3. At the same time, the positioning part 4 is used to assist in positioning, so as to realize the quick installation of the guide vane 6. After the guide vane 6 is installed, the end cap assembly 2 is covered on the end of the guide vane 6 to prevent the guide vane 6 from falling off the air outlet 1. In addition, since the guide vane 6 has a T-shaped slot 61 and the second mounting plate 32 of the frame 3 has a connecting part 33, the T-shaped slot 61 and the connecting part 33 are positioned and inserted together, so as to realize the guiding insertion of the guide vane 6, which facilitates the positioning and installation of the guide vane 6. While realizing the quick installation of the guide vane 6, the installation accuracy of the guide vane 6 is improved. When the curling iron is working, the air is discharged through the air outlet 5 and guided by the guide vane 6 to realize the blow-drying and styling of the hair on the surface of the curling iron.

[0052] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
