The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To achieve the above objectives, this utility model provides a left-right rotating module linkage air-blowing hair curling accessory, see reference. Figures 1-17 As shown, it includes: The outer cylinder 1 has an assembly plate 2 fixedly connected to its upper end face and an air guide duct 3 fixedly connected to its lower end face. The outer cylinder 1 has a number of assembly strip holes 101 arranged in a ring along its outer side wall. The outer cylinder 1 is fitted with a rotating cap 4, and the assembly plate 2 is provided with a limiting component 5 to limit the rotation angle of the rotating cap 4. Wind rib assembly 13, an integrally formed wind rib assembly 13 is installed inside the outer cylinder 1, and the upper end of the wind rib assembly 13 passes through the top surface of the outer cylinder 1 and is fastened to the swivel cap 4. The air guide plate 8 is provided with the mounting strip hole 101. Each air guide plate 8 extends arc-shaped on both sides along the long direction to form a left air outlet 11 and a right air outlet 12 with the outer side wall of the outer cylinder 1. The rotating cap 4 drives the air frame assembly 13 to rotate, causing the air guide plate 8 to swing, which is used to form an opening and closing cooperation with the left air outlet 11 or the right air outlet 12 of the outer cylinder 1.

[0022] In this embodiment, the outer cylinder 1 serves as the core supporting base, with its upper and lower ends fixedly connected to the assembly plate 2 and the air guide tube 3, respectively, forming a modular installation frame. This provides a stable assembly reference for the swivel cap 4, the air frame assembly 13, and the air guide plate 8. Multiple assembly slots 101 are used to match the installation requirements of the air guide plate 8, so that each air guide plate 8 and the side wall of the outer cylinder 1 enclose a left air outlet 11 and a right air outlet 12, which has a bidirectional air outlet structure. The movable design of the air guide plate 8 breaks through the limitations of the traditional fixed air outlet structure. The opening and closing of the air outlet is achieved by swinging. The overall structure abandons the complex gear transmission, is lightweight and highly efficient, and effectively solves the problems of cumbersome operation and fatigue of holding traditional accessories.

[0023] Further reference Figures 4-7 As shown, the air frame assembly 13 includes a hollow cylindrical air frame 6 and a rubber seal 7. The outer wall of the hollow cylindrical air frame 6 is provided with a plurality of recessed mounting grooves 601 arranged in a ring along the longitudinal direction. The hollow cylindrical air frame 6 is detachably connected to the rubber seal 7 through the recessed mounting grooves 601. The front and rear end faces of the hollow cylindrical air frame 6 are provided with recessed rings 701. The front and rear ends of the rubber seal 7 are integrally connected with rubber strip rings 607. The rubber strip rings 607 and the recessed rings 701 are correspondingly and tightly connected. The hollow cylindrical air frame 6 is formed in one piece and then formed together with the rubber seal 7 in a second piece to form a single unit.

[0024] In this embodiment, the hollow cylindrical wind frame 6 and the rubber seal 7 are an integral unit. The hollow cylindrical wind frame 6 is first molded in one step, and then the hollow cylindrical wind frame 6 is placed into a mold for secondary injection molding, so that the rubber seal 7 and the concave assembly groove 601 and concave ring 701 of the hollow cylindrical wind frame 6 are interlocked to form an integrated structure.

[0025] Furthermore, the upper center of the hollow cylindrical wind frame 6 is integrally formed with a foolproof concave connecting post 602, and the upper surface of the hollow cylindrical wind frame 6 is provided with a number of circular pins 603 arranged in a ring. The circular pins 603 and the foolproof concave connecting post 602 are integrally connected by a reinforcing rib 604. The circular pins 603 are located between two adjacent rubber seals 7. The reinforcing rib 604 enhances the connection strength between the circular pins 603 and the foolproof concave connecting post 602, avoids the breakage of the foolproof concave connecting post 602 due to long-term rotational stress, and improves the durability of the linkage structure.

[0026] Further reference Figures 8-9 As shown, the hollow cylindrical wind frame 6 has a central inner air duct 605 with end sealing at the center. The hollow cylindrical wind frame 6 has a number of lateral concave air duct openings 606 arranged between two adjacent concave assembly grooves 601. The central inner air duct 605 is connected to the lateral concave air duct openings 606. The inner side of the air guide plate 8 is integrally formed with a support protrusion ring 801 corresponding to the lateral concave air duct openings 606, forming air supply ducts on both sides.

[0027] In this embodiment, the external air source airflow is input into the central air duct 605 and outputs outward from several side-concave air duct openings 606 of the annular array. The airflow is evenly distributed and synchronously delivered to each air guide plate 8. The supporting protruding ring 801 is correspondingly supported on the side-concave air duct opening 606, so that the airflow forms a double-sided air supply duct at the air guide plate 8, guiding the airflow to flow directionally to the left air outlet 11 and the left air outlet 11.

[0028] Further reference Figure 9 As shown, the air guide plate 8 has a convex shaft 802 on both sides, the assembly plate 2 has a number of assembly pin holes 202, and the air guide tube 3 has a number of air guide pin holes 301. The convex shafts 802 at both ends of the air guide plate 8 are connected to the assembly pin holes 202 and the air guide pin holes 301 respectively. The upper end of the air guide plate 8 extends inward and is integrally formed with a connecting arm 803. The end of the connecting arm 803 is connected to the movable shaft of the round pin column 603. The air guide plate 8 has the convex shaft 802 as the central axis. Based on the rotation of the round pin column 603, the connecting arm 803 swings, so that the two sides of the air guide plate 8 swing to form an opening and closing cooperation with the left air outlet 11 or the right air outlet 12 respectively.

[0029] In this embodiment, the air guide plate 8 is designed to be axially connected to the assembly plate 2 and the air guide tube 3 via two protruding shafts 802 at both ends. The air guide plate 8 is set to rotate around the protruding shaft 802 as the central axis. The connecting arm 803 serves as a power transmission bridge, and its end is connected to the movable shaft of the round pin 603. This realizes the linkage of the rotation of the hollow cylindrical wind frame 6, the swing of the connecting arm 803, and the deflection of the air guide plate 8. This linkage method has a simple and compact structure, effectively reducing the overall weight of the accessories and alleviating fatigue from holding them for a long time. The arc-shaped extension design of the air guide plate 8 allows it to form a tight opening and closing fit with the side wall of the outer cylinder 1 when it swings. When one side is pressed against the rubber seal 7, it can completely block the corresponding air outlet, while the other side opens naturally, realizing the rapid switching of the air outlet direction of the left air outlet 11 and the left air outlet 11.

[0030] Further reference Figure 11As shown, the rotating cap 4 has an integrally formed central hole 401. The central hole 401 is provided with a foolproof protruding connector 402. The foolproof protruding connector 402 is used to engage with the foolproof concave connector 602. The foolproof protruding connector 402 is fastened to the foolproof concave connector 602 by screws, so that the hollow cylindrical wind frame 6 can be rotated when the rotating cap 4 is rotated.

[0031] Further reference Figures 10-12 As shown, the limiting component 5 includes a connecting block 501 and a spring 502. A stud 201 is integrally formed on the assembly plate 2. The connecting block 501 has a through hole 503 for fitting the stud 201. The connecting block 501 is fastened to the stud 201 by screws. The assembly plate 2 has a strip hole 203. The lower part of the connecting block 501 has a positioning pin 504 for moving into the strip hole 203. The spring 502 is installed in the through hole 503. The two ends of the spring 502 abut against the inner wall of the through hole 503 and the outer wall of the stud 201, respectively. The bottom inner side of the swivel cap 4 has an inwardly convex arc strip 403. The two sides of the inwardly convex arc strip 403 have arc-shaped recesses 404. The side of the connecting block 501 has an arc-shaped protrusion 505. The arc-shaped protrusion 505 engages with the annular recess to limit the rotation angle of the swivel cap 4.

[0032] In this embodiment, the spring 502 inside the through hole 503 is always in a pre-compressed state, so that the arc-shaped protrusion 505 of the connecting block 501 can abut against the inner arc-shaped strip 403 of the rotating cap 4. The arc-shaped trajectory of the inner arc-shaped strip 403 is adapted to the rotation path of the rotating cap 4, and the arc-shaped recesses 404 on both sides correspond to the extreme positions of left-hand rotation and right-hand rotation, respectively. When the rotating cap 4 rotates clockwise or counterclockwise, it rotates until the arc-shaped protrusion 505 is aligned with the arc-shaped recess 404, and the spring 502 resets, causing the arc-shaped protrusion 505 to engage with the arc-shaped recess 404, forming the limits for left-hand rotation and right-hand rotation.

[0033] Further reference Figure 13 As shown, the air duct 3 is provided with a circular ring 10, and a rubber ring 14 is fixedly connected to the end face of the circular ring 10. The inner wall of the air duct 3 is provided with a number of grooves 302 in a circular array. The outer wall of the circular ring 10 is integrally formed with a number of inclined end blocks 1001. The inclined end blocks 1001 are connected to the grooves 302 in a clamping manner. The circular ring 10 is used to connect with air source equipment such as blowers. The rubber ring 14 ensures airtight connection. The sealing performance of the rubber ring 14 can reduce airflow leakage.

[0034] Furthermore, a cap 9 is fitted onto the top of the cap 4, and several locking blocks 405 are provided on the upper inner wall of the cap 4. Several slots 901 are provided on the side of the cap 9, and the locking blocks 405 are snapped together with the slots 901.

[0035] Working principle: Connect the end of the air guide tube 3 to a blower or other air source device. The airflow generated by the air source enters the central inner air duct 605 of the hollow cylindrical air frame 6 through the air guide tube 3. Since the end of the central inner air duct 605 is sealed, the airflow is evenly distributed to the direction of the air guide plate 8 along the lateral concave air duct opening 606 of the annular array, forming a double-sided directional airflow output at the air guide plate 8. When the rotating cap 4 is rotated, the hollow cylindrical wind frame 6 rotates synchronously. The round pin 603 on the hollow cylindrical wind frame 6 rotates with it and pushes the connecting arm 803, causing the air guide plate 8 to swing around the convex shaft 802 as the central axis. When the rotating cap 4 rotates, the spring 502 resets and pushes the arc-shaped protrusion 505 into the arc-shaped concave position 404. The positioning of the rotating cap 4 is completed. One side of the air guide plate 8 swings to fit tightly with the rubber seal 7 to achieve the sealing of the corresponding air outlet. The other side forms an open channel with the side wall of the outer cylinder 1 to complete the switching of the air outlet direction. The air outlet of the open channel directs the airflow outwards, and the airflow forms a spiral airflow field along the side wall of the outer cylinder 1. When the left air outlet 11 is open, a counterclockwise spiral airflow is formed, and when the right air outlet 12 is open, a clockwise spiral airflow is formed. The traction force of the airflow drives the hair strands to wrap around the outer wall of the outer cylinder 1, and with the help of hot air, the hair can be curled and styled.

[0036] refer to Figure 14 and Figure 15 As shown, when the swivel cap 4 rotates counterclockwise, it drives the air frame assembly 13 to rotate counterclockwise, and the round pin 603 also rotates counterclockwise, causing the connecting arm 803 to swing. Based on the convex shaft 802 as the central axis, the right side of the air guide plate 8 abuts against the rubber seal 7, so that the right air outlet 12 is closed and the left air outlet 11 is opened, forming a situation where the swivel cap 4 rotates counterclockwise and the left air outlet 11 blows air out in a curling motion.

[0037] refer to Figure 16 and Figure 17 As shown, when the swivel cap 4 rotates clockwise to the right, it drives the air frame assembly 13 to rotate clockwise. The round pin 603 also rotates clockwise, causing the connecting arm 803 to swing. The left side of the air guide plate 8, based on the convex shaft 802 as the central axis, abuts against the rubber seal 7, causing the left air outlet 11 to close and the right air outlet 12 to open, forming a clockwise airflow from the right air outlet 12 of the swivel cap 4.

[0038] In summary, this utility model provides a left-right rotating module linkage air-blowing hair curling accessory. By rotating the rotating cap 4, the round pin 603 on the hollow cylindrical wind frame 6 is rotated. The rotation of the round pin 603 causes the connecting arm 803 to swing. Using the air guide plate 8 with the convex shaft 802 as the central axis, the two sides of the air guide plate 8 swing to form an opening and closing cooperation with the left air outlet 11 or the right air outlet 12 respectively. The structure is optimized, the design is ingenious, the operation is simple, and it meets the needs of hair curling, with better convenience.
