[0047] As shown in Figure 5 , the curling shell 2 is in a tubular one-piece structure, the curling shell 2 includes a connecting rib 22 and a plurality of arc-shaped plates 21 arranged along the circumferential direction of the curling shell 2, the plurality of arc-shaped plates 21 are uniformly distributed around the axis of the curling shell 2, and each arc-shaped plate 21 extends along the axial direction. The connecting portions of the adjacent arc-shaped plates 21 form the second air outlet 23, and the adjacent arc-shaped plates 21 are connected by the connecting rib 22. In this embodiment, the curling shell 2 is integrally formed of metal material, and the existing curling shell 2 is generally injection molded by plastic. The metal material is preferably aluminum or aluminum alloy material. The use of aluminum or aluminum alloy material makes the curling shell 2 light in weight, easy to process, and good in heat transfer effect. The curling shell 2 is first formed by extrusion of aluminum, and then the second air outlet 23 is formed by stamping. The thickness of the arc-shaped plate 21 can be relatively small, thereby reducing the weight of the air nozzle.

The design of the air outlet formed by the air outlet satisfies the wind direction control of the air outlet without relying on the inner cylinder structure, and reduces the difficulty of manufacturing and assembling the curling shell.

[0049] As shown in Figure 7 , in this embodiment, the first inclined surface 211 and the second inclined surface 221 are parallel to each other, and the distance d between the first inclined surface 211 and the second inclined surface 221 is 0.3-0.5mm. Referring to Figure 6The connecting rib 22 is connected with the first inclined surface 211 and the second inclined surface 221, which is beneficial to keep the first inclined surface 211 and the second inclined surface 221 in parallel.

[0050] As shown in Figure 7 and Figure 8 , the first curved surface 210 includes a main curved surface 212 and a transition curved surface 213. The transition curved surface 213 is connected with the first inclined surface 211 on one side and connected with the main curved surface 212 on the other side.

The included angle a between the tangent line Y of the connection between the main curved surface 212 and the transition curved surface 213 and the air outlet direction X of the second air outlet 23 is 20-30 degrees. The included angle a can be set as needed. The smaller the included angle a, the better the curling effect. When the included angle a is 20 degrees, the best curling effect can be achieved.

[0051] The arc plates 21 of the curling shell 2 can be 6-9. In this embodiment, six arc plates 21 are taken as an example. The thickness of the arc plate 21 is 0.8-2.5 mm. The thickness of 1.0-1.5 mm is beneficial to the processing of the curling shell 2 and ensures that the material is not deformed, that is, the stability.

[0052] As shown in Figure 8 , in this embodiment, the maximum outer diameter D of the arc plate 21 is 15-20 mm. The maximum outer diameter D of the arc plate 21: the distance d between the first inclined surface 211 and the second inclined surface 221 = 30-70.

[0053] As shown in Figure 8 , the arc plates 21 on the curling shell 2 are petal-shaped. The maximum outer diameter of the curling shell 2 overlaps with the outer diameter arc line part of the arc plate 21.

[0054] The first air outlet 12 and the second air outlet 23 are distributed in a staggered manner. The air flow from the first air outlet 12 first circulates along the inner wall surface of the curling shell 2 to the second air outlet 23, and finally the air flow is guided out of the second air outlet 23 and circulates along the outer wall of the curling shell 2.

[0055] The first air outlet 12 is provided with a plurality of first air outlets 12. The plurality of first air outlets 12 are circumferentially distributed on the outer surface of the inner cylinder 1, and the plurality of first air outlets 12 are arranged along the length direction of the inner cylinder 1. The openings of the plurality of first air outlets 12 gradually increase or gradually decrease or do not change along the length direction of the inner cylinder 1.

[0056] At least one sealing element 3 is provided between the inner cylinder 1 and the curling shell 2. The inner ring of the sealing element 3 engages with the inner cylinder 1, and the outer ring of the sealing element 3 is adapted to the shape of the curling shell 2 to facilitate the installation and positioning of the curling shell 2. The outer ring of the sealing element 3 abuts against the inner circumferential surface of the curling shell 2. In this embodiment, at least one sealing element 3 includes a pair of sealing elements 3, which are located at both ends of the inner cylinder 1.

[0057] The outer sides of both ends of the inner cylinder 1 protrude outward to form protrusions 13, and openings 130 are provided on the protrusions 13. The sealing element 3 has a first locking block 30 and a second locking block 31 protruding from opposite sides, symmetrically distributed on both sides of the sealing element 3. When the curling shell 2 needs to be installed in reverse, the sealing element 3 is fitted onto the inner cylinder 1 in the opposite direction. The first locking block 30 of the sealing element 3 installed at the upper end of the inner cylinder 1 and the first locking block 30 of the sealing element 3 installed at the lower end of the inner cylinder 1 are both installed downwards. At this time, the first locking block 30 of the sealing element 3 installed at the upper end of the inner cylinder 1 and the opening slot 130 at the upper end of the inner cylinder 1 are connected. The groove 130 is engaged; the second locking block 31 of the seal 3 installed at the lower end of the inner cylinder 1 is engaged with the opening groove 130 at the lower end of the inner cylinder 1; when the hair curler shell 2 needs to be installed in the forward direction, the seal 3 is sleeved on the inner cylinder 1 in the forward direction, and the first locking block 30 of the seal 3 installed at the upper end of the inner cylinder 1 and the first locking block 30 of the seal 3 installed at the lower end of the inner cylinder 1 are both installed upward. At this time, the second locking block 31 of the seal 3 installed at the upper end of the inner cylinder 1 is engaged with the opening groove 130 at the upper end of the inner cylinder 1; the first locking block 30 of the seal 3 installed at the lower end of the inner cylinder 1 is engaged with the opening groove 130 at the lower end of the inner cylinder 1.

[0058] The end head 15 of the inner cylinder 1 is provided with a fixing groove 150 for receiving the first card block 30 or the second card block 31 at the position corresponding to the first card block 30 or the second card block 31.

[0059] The sealing element 3 is either ring-shaped or strip-shaped. In this embodiment, the sealing element 3 at the upper end of the inner cylinder 1 is ring-shaped, and the sealing element 3 at the lower end of the inner cylinder 1 is strip-shaped. It is formed by cutting the ring-shaped sealing element at the position corresponding to the first locking block 30. The reason is that the assembly of the sealing element 3 at the lower end of the inner cylinder 1 would be inconvenient because it would have to be rolled from the upper end of the inner cylinder 1 to the lower end. Therefore, it is cut into strip shape. Then, the first locking block 30 is inserted into the opening groove 130 or the fixing groove 150, making it easier to assemble the sealing element 3 at the lower end of the inner cylinder 1.

[0060] In this embodiment, the lower end face of the upper cover 5 abuts against the side of the sealing member 3 to form a seal, and the inner circumferential surface of the upper cover 5 abuts against the outer side of the locking block 30.

[0061] like Figure 9 As shown, a curling iron according to an embodiment of the present invention includes the above-mentioned suction curling nozzle and main body 4, wherein the suction curling nozzle is fixedly connected to the main body 4.

[0062] In use, the main body 4 is used as a wind end, when the wind blows, the wind flow first enters the inner cylinder 1 through the first air inlet 11 into the air inlet channel 10, because the first air outlet 12 on the surface of the support cylinder 14 is connected with the air inlet channel 10, the wind flow is guided out from the first air outlet 12, because the first air outlet 12 and the second air outlet 23 are distributed in staggered positions, so that the wind flow from the first air outlet 112 to the second air outlet 23 is guided along the inner wall of the curling shell 2 to the second air outlet 23, and finally the wind flow is guided out from the second air outlet 23 and along the outer wall of the curling shell 2.

[0063] Unlike the prior art, the air outlet of the curling shell 2 of the prior art is provided with a wind guide rib, and the gap of the wind guide rib of the curling shell 2 needs to be matched with the inner cylinder 1; or the existing curling shell 2 is spliced by a plurality of arc-shaped plates 21, so that the structure is complex and difficult to assemble. The curling shell 2 in the embodiment is not provided with a wind guide rib, so that the curling shell 2 is easier to be integrally formed, the manufacturing requirements and related processes are reduced, and the user can control the air outlet gap size of the integrally formed curling shell 2 when using the product to curl hair, so that the hair flows along the wind direction and is blown out along the outer wall of the curling shell 2, the hair is not easy to be entangled together when curling, and the user has a better use experience. At the same time, the curling shell 2 of the utility model is made of metal material, has good heat conductivity, improves the speed of hair heating and shaping, and has more durable shaping effect, which meets the needs of most users for shaping effect.

[0064] The above embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent.
