Detailed Implementation

[0030] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1-7 As shown, this utility model proposes a hair curling iron, including a first barrel 1 and a second barrel 2. By the relative movement between the first barrel 1 and the second barrel 2, different air outlet channels are constructed to facilitate blowing air in different directions, thereby making it easy to switch the blowing direction.

[0032] The first cylinder 1 has a forward air outlet channel 3 and a reverse air outlet channel 4 on its peripheral side. It should be noted that the forward air outlet channel 3 and the reverse air outlet channel 4 have opposite air outlet directions. One of them is clockwise and the other is counterclockwise. Specifically, the forward air outlet channel refers to the air duct that runs clockwise from the inside of the first cylinder 1 to the outside, with the central axis of the first cylinder 1 as the center. The reverse air outlet channel 4 refers to the air duct that runs counterclockwise from the first cylinder 1 to the outside, with the central axis of the first cylinder 1 as the center. Thus, the air blown out from the forward air outlet channel 3 and the air blown out from the reverse air outlet channel 4 form two opposite directions.

[0033] The second cylinder 2 is slidably sealed inside the first cylinder 1, and the second cylinder 2 is coaxially arranged with the first cylinder 1; one end of the second cylinder 2 is provided with an air inlet 6, and the second cylinder 2 is provided with a first air outlet 5; specifically, the relative sliding direction between the second cylinder 2 and the first cylinder 1 can be the axial direction or along a certain spiral direction.

[0034] The second cylinder 2 has at least two positions along the axial direction of the first cylinder 1: In the first position, the first air outlet 5 is connected to the forward air outlet channel 3. In this position, gas entering the second cylinder 2 from the air inlet 6 enters the forward air outlet channel 3 through the first air outlet 5 and is discharged from the forward air outlet channel 3. In the second position, the first air outlet 5 is connected to the reverse air outlet channel 4. In this position, gas entering the second cylinder 2 from the air inlet 6 enters the reverse air outlet channel 4 through the first air outlet 5 and is discharged from the reverse air outlet channel 4. When the second cylinder 2 is in the first position, the first air outlet 5 is only connected to the forward air outlet channel 3 and not to the reverse air outlet channel 4. When the second cylinder 2 is in the second position, the first air outlet 5 is only connected to the reverse air outlet channel 4 and not to the forward air outlet channel 3. In specific implementation, the switching between the first and second positions can be achieved by moving the second cylinder 2 along the axial direction or by rotating it along the spiral direction.

[0035] Taking the switching between the first and second positions by moving the second cylinder along the axial direction as an example, the user can choose to adjust according to their own needs. Specifically, if the user wants to adjust the air outlet direction, they only need to push or pull the second cylinder 2 along the axial direction to switch from the first position to the second position, or from the second position to the first position, so that the gas enters the reverse air outlet channel 4 through the first air outlet 5 and is discharged from the reverse air outlet channel 4, or the gas enters the forward air outlet channel 3 through the first air outlet 5 and is discharged from the forward air outlet channel 3, thereby achieving the Coanda effect curling.

[0036] To facilitate the switching of the second cylinder 2 between the first and second positions, the following measures are adopted:

[0037] The end of the second cylinder 2 furthest from the air inlet 6 is a sealed end, on which a push rod 7 is fixedly installed. The push rod 7 extends outward from the first cylinder 1, and a positioning groove 8 is provided on the push rod 7, which is arranged along the axial direction of the second cylinder 2. The first cylinder 1 is provided with a positioning slider 9 that slides in cooperation with the positioning groove 8, and the positioning slider 9 is fixedly connected to the first cylinder 1. The cooperation between the positioning slider 9 and the positioning groove 8 can play a limiting role, preventing the second cylinder 2 from rotating circumferentially relative to the first cylinder 1 when the push rod 7 is pushed or pulled.

[0038] To better facilitate user judgment of whether the second cylinder 2 has moved to the first or second position, limiting blocks can be installed at both ends of the positioning groove 8. When the push rod 7 is pushed or pulled, causing the limiting block at one end of the positioning groove 8 to abut against the positioning slider 9, it can be determined that the second cylinder 2 has moved to the first or second position. For example, when the push rod 7 is pushed, causing the limiting block at the end of the positioning groove 8 away from the second cylinder 2 to abut against the positioning slider 9, the second cylinder 2 moves to the first position; when the push rod 7 is pulled, causing the limiting block at the end of the positioning groove 8 close to the second cylinder 2 to abut against the positioning slider 9, the second cylinder 2 moves to the second position. To prevent the second cylinder 2 from moving again when it is in the first or second position, a locking component can be installed between the push rod 7 and the first cylinder 1. The locking component can be a positioning pin and a positioning hole, with the positioning pin slidably installed on the first cylinder 1 and the positioning hole opened on the push rod 7. In some implementations, a return spring can be used to facilitate switching between the first and second positions. For example, the transition from the second position to the first position can be achieved by using a return spring.

[0039] As one implementation method, see Figures 3-6 As shown, the first cylinder 1 is provided with a first cavity 10 and a second cavity 11. The first cavity 10 and the second cavity 11 are both arranged along the axial direction of the first cylinder 1. The first cavity 10 is connected to the forward air outlet channel 3, and the second cavity 11 is connected to the reverse air outlet channel 4.

[0040] The inner wall of the first cylindrical body 1 is provided with a second air outlet 12 and a third air outlet 13. The second air outlet 12 communicates with the first cavity 10, and the third air outlet 13 communicates with the second cavity 11. When the second cylindrical body 2 is in the first position, the first air outlet 5 communicates with the second air outlet 12; when the second cylindrical body 2 is in the second position, the first air outlet 5 communicates with the third air outlet 13. Specifically, the second air outlets 12 are arranged in multiple rows along the circumference of the first cylindrical body 1, with each row of second air outlets 12 evenly distributed in the axial direction. The third air outlets 13 are arranged in multiple rows along the circumference of the first cylindrical body 1, with each row of third air outlets 13 evenly distributed in the axial direction. In the axial direction, the second air outlets 12 and the third air outlets 13 are staggered.

[0041] The first air outlet 5 is elongated and arranged along the circumference of the second cylinder 2. The second air outlet 12 and the third air outlet 13 are both elongated holes arranged along the circumference of the first cylinder 1; the corresponding arcs of the second air outlet 12 and the third air outlet 13 are equal and not greater than half the arc of the corresponding arc of the first air outlet 5. The second air outlet 12 and the third air outlet 13 are staggered. Specifically, the first air outlets 5 are arranged in multiple rows along the circumference of the first cylinder 1, with each row of first air outlets 5 evenly distributed in the axial direction; each first air outlet 5 corresponds to one second air outlet 12 and one third air outlet 13. In the first position, the first air outlet 5 is connected to the corresponding second air outlet 12, but not to the third air outlet 13; in the second position, the first air outlet 5 is connected to the corresponding second air outlet 12, and also to the corresponding third air outlet.

[0042] Furthermore, the first cylinder 1 includes an inner cylinder 14 and an outer cylinder 15, which are coaxially arranged. A partition 16 is provided between the inner cylinder 14 and the outer cylinder 15, and the partition 16 is sealed to both the inner cylinder 14 and the outer cylinder 15. The partition 16 is arranged along the axial direction of the first cylinder 1. The first cavity 10 and the second cavity 11 are both formed by two adjacent partitions 16, the inner cylinder 14, and the outer cylinder 15. The first cavity 10 and the second cavity 11 are spaced apart along the circumferential direction of the first cylinder 1. Both ends of the first cavity 10 and the second cavity 11 are sealed to prevent gas entering the first cavity 10 and the second cavity 11 from flowing out from both ends.

[0043] The first cylinder 1 also includes an air guide plate 17; the air guide plate 17 is fixedly installed on the outer cylinder 15, and the outer cylinder 15 has a fourth air outlet 18 and a fifth air outlet 19. The fourth air outlet 18 is connected to the first cavity 10, and the fifth air outlet 19 is connected to the second cavity 11. One side of the air guide plate 17, together with the fourth air outlet 18 and the outer wall of the outer cylinder 15, forms a forward air outlet channel 3, which refers to the side of the air guide plate 17 near the fourth air outlet 18. The other side of the air guide plate 17, together with the fifth air outlet 19 and the outer wall of the outer cylinder 15, forms a reverse air outlet channel 4, which refers to the side of the air guide plate 17 near the fifth air outlet 19. In specific implementation, the air guide plate 17 is fixedly connected to the outer wall of the outer cylinder 15 through a connecting plate. The connecting plate is arranged along the axial direction of the outer cylinder 15 and is located between two adjacent fourth air outlets 18 and fifth air outlets 19. By setting the air guide plate 17, the blown air can have a certain angle, so that the hair can be close to the outer edge of the curling iron.

[0044] The outer wall of the outer cylinder 15 is provided with protrusions 20 along the axial direction. The protrusions 20 are spaced apart from the air guide plates 17, and each of the protrusions 20 has a guide surface on its side near the two adjacent air guide plates 17. By providing the protrusions 20, it is possible to prevent the air blown out of the forward air outlet 3 from blowing hair into the reverse air outlet 4, and to prevent the air blown out of the reverse air outlet 4 from blowing hair into the forward air outlet 3, so as to make it easier to roll the hair around the outer circumference of the first cylinder 1 by utilizing the Coanda effect. On the other hand, the protrusions 20 can be used to adjust the direction of the blown air.

[0045] Along the axial direction of the first cylinder 1, the distance between two adjacent first air outlets 5 in the same row, the distance between two adjacent second air outlets 12 in the same row, and the distance between two adjacent third air outlets 13 in the same row are all equal.

[0046] One end of the first cylinder 1 is an open end, and the air inlet 6 is close to the open end; the open end of the first cylinder 1 is provided with a claw that engages with the air outlet of the air supply equipment, so as to facilitate quick connection with the air supply equipment.

[0047] This invention enables quick switching of the airflow direction of a hair curler, eliminating the need for the user to rotate the curler and improving user convenience. Specifically, in the first position, the airflow sequentially passes through the air inlet 6, the first air outlet 5, the second air outlet 12, the first cavity 10, the fourth air outlet 18, and the forward airflow channel 3. In the second position, the airflow sequentially passes through the air inlet 6, the first air outlet 5, the third air outlet 13, the second cavity 11, the fifth air outlet 19, and the reverse airflow channel 4.
