DETAILED DESCRIPTION

Referring to FIG. 1 to FIG. 7. Technical solutions used in specific embodiments are as follows: A curling iron capable of curling hair in two directions includes a rotary outer shell 1, a rotating body 2, and a fixing knob 3. The rotating body 2 is sleeved in the rotary outer shell 1, and the fixing knob 3 is disposed at a top of the rotary outer shell 1 and connected with the rotating body 2. The rotary outer shell 1 includes a ventilation rod body 1-1, and an air duct cover sheet 1-2. The rotating body 2 includes a partition plate 2-1 and a ventilation bottom cover 2-2. The partition plate 2-1 is disposed on the ventilation bottom cover 2-2. The air duct cover sheets 1-2 are clamped on a surface of the ventilation rod body 1-1, where each air duct cover sheet is secured to one of a plurality of partition blocks 1-1-4 disposed on the outer surface of the rotary shell between the air exits of the first and second rows of air outlets. The ventilation rod body 1-1 includes a plurality of arc-shaped plates 1-1-1, and a plurality of elongated segments (unlabeled), where the plurality arc-shaped plated and the plurality of elongated segments are arranged in an alternating manner such that their respective inner and outer surfaces are continuous and define inner and outer surfaces of the rotary outer shell. Each elongated segment of the plurality of elongated segments includes a first fixing groove 1-1-2 on an inner surface of the elongated segment where the first fixing groove extends along the length of the segment and is disposed between two adjacent ones of the arc-shaped plates 1-1-1. Air outlets 1-1-3 are symmetrically disposed on both sides of the arc-shaped plate 1-1-1. A quantity of the arc-shaped plates 1-1-1 corresponds to a quantity of the air duct cover sheets 1-2. When the rotating body 2 is rotated, the partition plate 2-1 may move between the first fixing grooves 1-1-2. When the partition plate is close to the air outlet 1-1-3 on any side, air flow from a blowing mechanism enters from the ventilation bottom cover 2-2, is separated by the partition plate 2-1, blown out from the air outlet 1-1-3 on the other side, pressed toward both sides through the air duct cover sheet 1-2, and then blown out. Therefore, air may be blown out from the curling iron, so that the curling iron may be conveniently used by one hand in a daily curling process. This improves curling efficiency.


Further, a partition block 1-1-4 is disposed between the air outlets 1-1-3. A first fixing strip 1-2-1, a second fixing strip (1-2-2), and a second fixing groove 1-2-3 are disposed in a concave surface of the air duct cover sheet 1-2. The second fixing groove (1-2-3) is disposed between the first fixing strip 1-2-1 and the second fixing strip 1-2-2. The partition block 1-1-4 limits the first fixing strip 1-2-1 and the second fixing strip 1-2-2, to prevent the air duct cover sheet 1-2 from moving.


Further, a width of the first fixing groove 1-1-2 is larger than a thickness of the partition plate 2-1, and the partition plate 2-1 is movably connected with the first fixing groove 1-1-2. Because the thickness of the partition plate 2-1 is smaller than the width of the first fixing groove 1-1-2, when the rotating body 2 is rotated, the partition plate 2-1 may move between the first fixing grooves 1-1-2.


Further, the second fixing groove 1-2-3 is connected with a bump of a first fixing groove 1-1-2.


Further, a fixed clamping head 2-3 is disposed on an outer side of the ventilation bottom cover 2-2. The fixed clamping head 2-3 is configured to connect and fix a blowing device.


A working principle of the invention is as follows: The quantity of arc-shaped plates 1-1-1 and the quantity of air duct cover plates 1-2 are set based on an actual requirement, to achieve different air outlet effect. The air duct cover piece 1-2 is disposed on the ventilation rod body 1-1, the second fixing groove 1-2-3 is connected with the bump of the first fixing groove 1-1-2 and is clamped on the first fixing groove 1-1-2 through the first fixing strip 1-2-1 and the second fixing strip 1-2-2, and the partition block 1-1-4 limits the first fixing strip 1-2-1 and the second fixing strip 1-2-2 to prevent the air duct cover sheet 1-2 from moving. The rotating body 2 is sleeved in the rotary outer shell 1, and the partition plate 2-1 is inserted into the first fixing groove 1-1-2. Because the thickness of the partition plate 2-1 is small than the width of the first fixing groove 1-1-2, when the rotating body 2 is rotated, the partition plate 2-1 may move between the first fixing grooves 1-1-2. When the partition plate is close to the air outlet 1-1-3 on any side, air flow from a blowing mechanism enters from the ventilation bottom cover 2-2, is separated through the partition plate 2-1, and blown out from the air outlet 1-1-3 on the other side. Therefore, an air outlet direction may be adjusted by the rotating body 2, so that air may be adjustably blown out from the curling iron, which greatly facilitates daily curling. This improves curling efficiency.


The foregoing descriptions are only used to describe the technical solutions of the present disclosure, but are not limited thereto. Any modification, equivalent replacement made by ordinary technicians for the technical solutions of the invention within the spirit and principle of the invention should be included within the scope of the claims of the invention.
