[0002] Hair styling devices such as hair dryers are typically equipped with multiple nozzles to meet different hair styling needs. These include round nozzles, flat nozzles, and straightening comb nozzles. Traditional nozzles have fixed airflow directions, requiring users to manually adjust the hair dryer's angle to direct the airflow in different directions for styling. However, this requires repeated adjustments to the grip angle, which is tiring, and in certain areas, such as the back of the head, the user's hand rotation is limited, making these areas difficult to reach.

The air outlet is rotatably located at the second end of the connecting structure, and has an air outlet, which is connected to the fan body via the connecting structure. The airflow generated inside the fan body can enter the connecting structure, flow towards the air outlet, and be blown out from the air outlet for the user. Moreover, the air outlet is designed to be long and narrow, and the flat air outlet makes the airflow more concentrated and the airflow speed greater. The airflow can be blown out in a roughly "I" shape, and the airflow direction is more unidirectional. Therefore, when blowing on the user's hair, the hair is less likely to become messy and can be better combed in one direction. Furthermore, the air outlet can rotate relative to the connecting structure, making the angle between the length direction of the air outlet and the rotation axis of the air outlet adjustable. In other words, the air outlet direction can be adjusted. Thus, when styling their own hair, users can directly change the air outlet direction by driving the air outlet to rotate, without needing to move their hands to adjust the direction. Obviously, this is more convenient and less strenuous to operate. Attached Figure Description

[0050] This utility model provides a rotary nozzle 100, which is suitable for use in hair styling equipment and is designed for use with a blower body. For details, please refer to... Figures 1 to 2 In this embodiment, the rotary nozzle 100 includes a connecting structure 1 and an air outlet 2. The connecting structure 1 has a first end and a second end arranged opposite to each other, and the first end of the connecting structure 1 is adapted to be detachably connected to the fan body. The air outlet 2 is rotatably disposed at the second end of the connecting structure 1. The air outlet 2 is provided with an air outlet 2111, and the air outlet 2111 is adapted to communicate with the fan body through the connecting structure 1. The air outlet 2111 is elongated. By rotating the air outlet 2 relative to the connecting structure 1, the angle between the length direction of the air outlet 2111 and the rotation axis of the air outlet 2 is adjustable.

[0051] In this embodiment, the first end of the connecting structure 1 is detachably connected to the fan body, making it easy to detach and install the entire rotary nozzle 100 from the fan body, facilitating the replacement of different types of rotary nozzles 100. The air outlet 2 is rotatably mounted on the second end of the connecting structure 1, and has an air outlet 2111, which is connected to the fan body via the connecting structure 1. The airflow generated inside the fan body can enter the connecting structure 1, flowing towards the air outlet 2111 and being blown out from the air outlet 2111 for the user. Furthermore, the air outlet 2111 is designed to be long and narrow, and its flat shape makes the airflow more concentrated and faster. The airflow can be blown out in a roughly straight line, with a more directional airflow. Therefore, when blowing onto the user's hair, the hair is less likely to become tangled and can be better combed in one direction. Furthermore, the air outlet 2 can be rotated relative to the connecting structure 1, so that the angle between the length direction of the air outlet 2111 and the rotation axis of the air outlet 2 can be adjusted, that is, the air outlet direction of the air outlet 2111 can be adjusted. Thus, when the user is styling their hair, they can directly change the air outlet direction by driving the air outlet 2 to rotate, without the need for the user to move their hands to adjust the direction. Obviously, the operation is more convenient and less strenuous.

[0052] Understandably, the rotation of the air outlet 2 can be driven by a drive device, allowing the air outlet 2 to rotate relative to the connecting structure 1. Driving the air outlet 2 to rotate via a drive device enables more precise angle adjustment and more intelligent operation. Alternatively, the air outlet 2 can be manually driven, making the structure of the rotary air outlet 100 simpler and less expensive.

[0053] Preferably, the air outlet 2 is rotatably sleeved on one end of the connecting structure 1, allowing the air outlet 2 to rotate relative to the connecting structure 1 by manual rotation. Specifically, in conjunction with Figure 2 and Figure 4 As shown, the air outlet 2 includes an air outlet component 21 and a housing component 22. The air outlet component 21 is hollow with openings at both ends. One end of the air outlet component 21 is rotatably connected to the connecting structure 1, and the air outlet 2111 is located at the other end of the air outlet component 21. The airflow blown from the fan body can enter the connecting structure 1 and then enter the air outlet component 21. The housing component 22 is connected to the air outlet component 21 and surrounds the outer periphery of the air outlet component 21. One end of the housing component 22 is rotatably fitted between the connecting structure 1 and the air outlet component 21, and the other end of the housing component 22 has a through hole, the shape of which matches the shape of the air outlet 2111. By stacking the housing component 22 and the air outlet component 21 in two layers, the strength of the air outlet 2 is increased, and the housing component 22 also provides heat insulation, preventing the user from being burned by excessively high temperatures at the air outlet component 21.

[0054] Furthermore, preferably, the shape of the outer shell 22 matches the shape of the air outlet 21, so that the outer shell 22 can fit the air outlet 21 better, and the air outlet 2 structure is more compact, thus making it smaller in size.

[0055] In particular, the connection methods of the air outlet 2 and the connecting structure 1 are slightly different depending on the specific structure of the outer shell 11 and the air outlet 21.

[0056] In one embodiment, such as Figure 4 As shown, the air outlet 21 has a first central cylindrical portion 211 and two first wing-shaped portions 212 located on both sides of the first central cylindrical portion 211. The two first wing-shaped portions 212 are symmetrically arranged on both radial sides of the first central cylindrical portion 211. Both the first central cylindrical portion 211 and the two first wing-shaped portions 212 are hollow, and a through hole is provided at the connection between the first central cylindrical portion 211 and the two first wing-shaped portions 212, so that the first central cylindrical portion 211 and the two first wing-shaped portions 212 are connected. The first central cylindrical portion 211 and the two first wing-shaped portions 212 are all open at the end away from the connecting structure 1, so as to jointly form the air outlet 2111. On the one hand, the overall volume of the air outlet 2 is smaller, and the length of the air outlet 2111 can be longer; on the other hand, it is more convenient for the user to drive the air outlet 2 to rotate by operating the first wing-shaped portions 212, making the rotation operation more convenient.

[0057] The shape of the outer casing 22 matches the shape of the air outlet 21. The outer casing has a second central cylindrical portion and two second wing-shaped portions located on both sides of the second central cylindrical portion, which are symmetrically arranged on both radial sides of the second central cylindrical portion. The second central cylindrical portion is fitted onto the outside of the first central cylindrical portion 211, and the two second wing-shaped portions respectively cover the outside of the two first wing-shaped portions 212.

[0058] Specifically, such as Figure 4 As shown, the outer casing 22 includes a first casing 221 and a second casing 222 that are connected to each other. The first casing 221 and the second casing 222 are respectively sandwiched on both sides of the air outlet 21 and are arranged symmetrically. The first casing 221 and the second casing 222 together enclose the aforementioned second central cylindrical portion and two second wing-shaped portions.

[0059] One of the first housing 221 and the second housing 222 is provided with a second hook 2121, and the other is provided with a second fastening part 223 that engages with the second hook 2121. The second hook 2121 and the second fastening part 223 engage to connect the first housing 221 and the second housing 222 and clamp the air outlet 21 therein. Alternatively, one of the first housing 221 and the air outlet 21 is provided with a second hook 2121, and the other is provided with a second fastening part 223 that engages with the second hook 2121. The second hook 2121 and the second fastening part 223 engage to connect the first housing 221 and the air outlet 21. And / or, one of the second housing 222 and the air outlet 21 is provided with a second hook 2121, and the other is provided with a second fastening part 223 that engages with the second hook 2121. The second hook 2121 and the second fastening part 223 engage to connect the second housing 222 and the air outlet 21. The first housing 221 and the second housing 222 are connected by ultrasonic welding. When assembling the air outlet 2, the first housing 221 or the second housing 222 can be snapped into the air outlet component 21 first, and then the second housing 222 or the first housing 221 can be placed on the outside of the air outlet component 21. Then, the first housing 221 and the second housing 222 are connected and fixed by ultrasonic welding to ensure the reliability of the connection between the first housing 221 and the second housing 222.

[0060] Multiple second hooks 2121 can be provided, and these hooks 2121 are located on the outer sides of the two first wing-shaped portions 212 of the air outlet 21, respectively, on both sides of each first wing-shaped portion 212 facing the first housing 221 and the second housing 222. The multiple second hooks 2121 are positioned near the air outlet 2111. Multiple second fasteners 223 are provided on the inner sides of both the first housing 221 and the second housing 222 to engage with the multiple second hooks 2121. This ensures a tighter connection between the first housing 221 and the second housing 222 and the air outlet 21, preventing the air outlet 2111 from cracking and avoiding accidental hair trapping.

[0061] While the air outlet 2 is securely connected to the connecting structure 1 and not easily detached, it can rotate relative to the connecting structure 1. Specifically, the connecting structure 1 is generally cylindrical with openings at both ends. The air outlet 2 is rotatably fitted onto the inner side of the opening at the second end of the connecting structure 1 at the end facing away from the air outlet 2111. Furthermore, a first connecting portion 2112 is provided inside the air outlet component 21, and a second connecting portion 124 is provided on the connecting structure 1. At least a portion of the second connecting portion 124 extends into the air outlet component 21 to engage with the first connecting portion 2112, allowing the air outlet component 21 to rotate relative to the connecting structure 1. Through the engagement of the first connecting portion 2112 and the second connecting portion 124, the air outlet 2 is prevented from detaching from the connecting structure 1 while ensuring its rotation.

[0062] Specifically, such as Figure 3 As shown, the first connecting portion 2112 is disposed inside the first central cylindrical portion 211, and the first connecting portion 2112 includes a first mounting hole 2112a disposed inside the first central cylindrical portion 211. The second connecting portion 124 includes a second mounting hole 1241 protruding from the second end of the connecting structure 1. At least a portion of the second mounting hole 1241 is inserted into the first mounting hole 2112a, such that one end of the first mounting hole 2112a abuts against the outer side of the second mounting hole 1241, and the end face of the second mounting hole 1241 can protrude from the other end of the first mounting hole 2112a. The rotary nozzle 100 also includes a connector, which passes through the second mounting hole 1241 and is pressed against the end face of the second mounting hole 1241 protruding from the first mounting hole 2112a, so as to restrict the air outlet 21 to the connecting structure 1 and allow the first mounting hole 2112a to rotate relative to the second mounting hole 1241. The air outlet 21 is limited along the axial direction of the connecting structure 1 by means of the second mounting hole 1241 and the connector, thereby preventing the air outlet 21 from detaching from the connecting structure 1. Moreover, since the connector is pressed against the end face of the second mounting hole 1241 but not completely pressed against the first mounting hole 2112a, the first mounting hole 2112a can rotate relative to the second mounting hole 1241, thereby allowing the air outlet 2 to rotate relative to the connecting structure 1.

[0063] The second mounting hole 1241 has a protruding support portion on its outer periphery. One end of the first mounting hole 2112a is pressed against the support portion, and the other end of the first mounting hole 2112a is limited by a connector. The end face of the second mounting hole 1241 is slightly protruding from the end face of the first mounting hole 2112a facing the air outlet 2111. This prevents the connector from being directly pressed against the first mounting hole 2112a, and allows the connector to limit the first mounting hole 2112a in its axial direction. This ensures that the air outlet 2 is reliably connected to the connecting structure 1 while allowing the air outlet 2 to rotate relative to the connecting structure 1. The connector can be a screw or bolt, etc. When assembling the air outlet 2 and the connecting structure 1, one end of the air outlet 2 can be fitted into the second end of the connecting structure 1 so that the first mounting hole 2112a can abut against the support. Then, the connector is inserted from the top opening of the first central cylindrical part 211 and screwed into the second mounting hole 1241, thus completing the assembly. The assembly method is simpler and more convenient.

[0064] In another embodiment, combined Figure 5 and Figure 6As shown, the air outlet 2121 has an air outlet body 213 and an air outlet head 214 located at the end of the air outlet body 213. One end of the air outlet body 213 is connected to the connecting structure 1, and the air outlet head 214 is located at the other end of the air outlet body 213. The air outlet 2111 is located at the end of the air outlet body 213 facing away from the connecting structure 1 and is roughly in the shape of an "I", making the air outlet cross-section of the air outlet 2111 more uniform, thereby making the air outlet more uniform. The shapes of the first housing 221 and the second housing 222 match the shape of the air outlet 21 to cover the outside of the air outlet 21.

[0065] Furthermore, combined Figures 7 to 9 As shown, one end of the connecting structure 1 is fitted inside the air outlet 21. The first connecting portion 2112 includes a first hook 2112b disposed on the inner ring side of the air outlet 21. The second connecting portion 124 includes a first fastening portion 1242 disposed on the outer ring side of the connecting structure 1. The end of the first hook 2112b abuts against the connecting structure 1 and is fastened to the first fastening portion 1242, allowing the first hook 2112b to rotate circumferentially relative to the first fastening portion 1242 relative to the first fastening portion 1242. By abutting against the connecting structure 1 with the end of the first hook 2112b, the movement of the air outlet 21 towards the connecting structure 1 is restricted in the axial direction along the connecting structure 1. By fastening the first hook 2112b to the first fastening portion 1242, the movement of the air outlet 21 away from the connecting structure 1 is restricted, thus restricting the air outlet 21 to the connecting structure 1 in the axial direction along the connecting structure 1. However, along the circumferential direction of the connecting structure 1, the air outlet 21 can also rotate relative to the connecting structure 1, thereby causing the air outlet nozzle to rotate to adjust the air outlet 2111 air outlet direction.

[0066] The first hook 2112b can be arranged in a ring at the end of the air outlet body 213. Alternatively, the first hook 2112b can be segmented, comprising multiple sub-hooks. The multiple sub-hooks are spaced apart circumferentially along the air outlet body 213, making each sub-hook easily elastically deformable, thus facilitating engagement with the first buckle 1242. The first buckle 1242 can be arranged in a complete ring to ensure better engagement strength.

[0067] In terms of the specific structure of the connection structure 1, the connection structure 1 includes a connection ring 11, a support ring 12, a circuit structure 13, a locking cylinder 14, and a telescopic ring 15.

[0068] The connecting ring 11 is roughly cylindrical, and its outer diameter matches the outer diameter of the interface of the fan body. This ensures better alignment of the rotary nozzle 100 with the fan body when it is installed, resulting in a smoother transition at the connection point.

[0069] The support ring 12 is fixedly sleeved on the inner side of the connecting ring 11. The second connecting part 124 is provided at one end of the support ring 12 and extends from the end of the connecting ring 11. The support ring 12 is connected to the first connecting part 2112 on the inner side of the air outlet 21 through the second connecting part 124, thereby restricting the air outlet 21 on the support ring 12 to ensure the position of the air outlet 21 and the entire air outlet 2 relative to the support ring 12.

[0070] In one embodiment, combined with Figure 3 and Figure 4 As shown, the support ring 12 includes a ring body 121, multiple support arms 122, and a support post 123. The ring body 121 is fixedly sleeved on the inner side of the connecting ring 11 and is located near the second end of the connecting ring 11. The multiple support arms 122 are spaced apart circumferentially along the ring body 121, and one end is connected to the ring body 121. The multiple support arms 122 protrude from the connecting ring 11 and extend into the air outlet 21. The support post 123 is located at the other end of the multiple support arms 122, and a second mounting hole 1241 is located on the support post 123. The multiple support arms 122 support the support post 123 on the inner side of the air outlet 21, so that the second mounting hole 1241 can be inserted into the first mounting hole 2112a, thereby ensuring accurate alignment of the first mounting hole 2112a and the second mounting hole 1241.

[0071] Preferably, the connecting ring 11, support ring 12, locking cylinder 14, and telescopic ring 15 are all coaxially arranged. They are also coaxially arranged with the second mounting hole 1241, so that the connection between the connecting structure 1 and the air outlet 21 is located in the middle of the air outlet 2. When the air outlet 2 rotates, it can rotate more effectively around the central axis of the connecting structure 1, resulting in more stable rotation.

[0072] In another embodiment, the first buckle 1242 is provided on the outer periphery of the end of the support ring 12, and when the support ring 12 is sleeved on the inner side of the air outlet 21, it can be engaged with the first hook 2112b of the air outlet 21.

[0073] Circuit structure 13 is located at the other end of support ring 12 and includes multiple connectors 131. Circuit structure 13 may also include a circuit board, with the multiple connectors 131 electrically connected to the circuit board. The multiple connectors 131 are adapted to mate with mating parts on the fan body to electrically conduct electricity between the fan body and the rotary nozzle 100, so that the fan body can identify the type of the rotary nozzle 100, thereby controlling the operation of the rotary nozzle 100 or controlling the flow rate and / or flow of the airflow entering the rotary nozzle 100. The circuit board is also generally arranged in a circular shape, so that the center of the circuit board can be passed through by airflow, to ensure that the airflow can pass through the connecting structure 1 to flow to the outlet nozzle 2.

[0074] The locking sleeve 14 is rotatably sleeved inside the support ring 12 and is suitable for docking and communicating with the fan body. One end of the air outlet 2 is rotatably sleeved between the connecting ring 11 and the locking sleeve 14. The locking sleeve 14 can be locked or unlocked with the fan body by rotation. This makes it easier to assemble and disassemble the connecting structure 1 when it is docked with the fan body.

[0075] The telescopic ring 15 is movably sleeved between the connecting ring 11 and the locking cylinder 14. The telescopic ring 15 has multiple through holes for the multiple connectors 131 to pass through in a one-to-one correspondence. The telescopic ring 15 has a travel along the axial direction of the locking cylinder 14, allowing it to have a first working state in which the multiple connectors 131 are retracted into the multiple through holes, and a second working state in which the multiple connectors 131 can extend out from the multiple through holes. After the rotary nozzle 100 is detached from the fan body, the telescopic ring 15 allows the multiple connectors 131 to retract within the telescopic ring 15, thus protecting the connectors 131 from damage or bending, which would affect the electrical connection performance after the rotary nozzle 100 is connected to the fan body. When the rotary nozzle 100 is connected to the fan body, the movement of the telescopic ring 15 allows multiple connectors 131 to be better exposed so as to connect and conduct electricity with the connecting parts on the fan body.

[0076] Among them, combined Figure 3 and Figure 4 As shown, a first sealing element 18 is provided between the air outlet 21 and the support ring 12. The first sealing element 18 is configured as a first sealing ring, which is sleeved on the outer periphery of the support ring 12 to seal between the air outlet 21 and the support ring 12. This ensures that while the air outlet 21 can rotate relative to the support ring 12, the airflow will not flow out from the gap between the two, and the airflow will flow into the inner cavity of the air outlet 21 from the inner ring side of the support ring 12.

[0077] A second sealing element 19 is also provided at the air outlet end of the rotating cylinder. The second sealing element 19 is a rubber ring. A stepped portion is formed on the inner side of the ring body 121 of the support ring 12, and the first sealing element 18 is sleeved on the outer side of the stepped portion. One end of the rubber ring is sleeved on the outer periphery of the air outlet end of the rotating cylinder, and the other end abuts against the inner side of the stepped portion, so that the rotating cylinder can still ensure a reliable seal with the support ring 12 during rotation, so that the airflow flows from the inner ring side of the rotating cylinder to the inner ring side of the support ring 12.

[0078] Furthermore, multiple guide posts 16 protrude from the support ring 12, and multiple telescopic springs 17 are fitted around each guide post 16. The two ends of each telescopic spring 17 abut against the support ring 12 and the telescopic ring 15, respectively. When the rotary nozzle 100 is in contact with the fan body, the abutting action at the connection point of the fan body pushes the telescopic ring 15 to move, exposing multiple connectors 131 to engage with the connecting parts on the fan body. At this time, each telescopic spring 17 is in an elastic energy-storing state. When the rotary nozzle 100 is removed from the fan body, the elastic restoring force of the multiple telescopic springs 17 pushes the telescopic ring 15 to move and reset, thus re-covering the multiple connectors 131 and protecting them.

[0079] Furthermore, a locking part 141 is provided on the outer periphery of the locking cylinder 14. When the telescopic ring 15 is in the first working state, the locking part 141 is located inside the telescopic ring 15; when the telescopic ring 15 is in the second working state, the locking part 141 is exposed outside the telescopic ring 15. The locking part 141 is adapted to engage with the mating part on the fan body in a wedge shape, so that when the rotary nozzle 100 is in contact with the fan body, the telescopic ring 15 can be driven to switch from the first working state to the second working state, and under the action of the locking part 141 and the mating part, the telescopic ring 15 is driven to rotate, so that the locking part 141 is adapted to engage with the fastening part inside the fan body, thereby fixing the rotary nozzle 100 to the fan body.

[0080] The locking part 141 includes a locking protrusion 1411 protruding from the outer periphery of the locking cylinder 14. The locking protrusion 1411 has a first wedge-shaped surface and a limiting groove is provided at the interface of the fan body. A second wedge-shaped surface is formed in the limiting groove to wedge with the first wedge-shaped surface. When the rotary nozzle 100 is inserted into the interface of the fan body, the second wedge-shaped surface gradually wedges with the first wedge-shaped surface, thereby driving the locking cylinder 14 to rotate relative to the fan body. This causes the overlap area between the second wedge-shaped surface and the first wedge-shaped surface to gradually increase along the axial direction of the interface of the fan body, forming a stop fit in the axial direction and restricting the movement of the rotary nozzle 100 relative to the fan body.

[0081] Furthermore, multiple locking protrusions 1411 are provided, and the multiple locking protrusions 1411 and multiple limiting grooves are arranged in a one-to-one correspondence. The rotary nozzle 100 and the fan body form multiple anti-stopping fits in the axial direction, which can better ensure the stability of the rotary nozzle 100 installation.

[0082] This utility model also provides a hair styling device, which includes a blower body and the aforementioned rotary nozzle 100. The rotary nozzle 100 is detachably connected to the blower body, making it easier to assemble and disassemble the rotary nozzle 100 from the blower body. The blower body can be configured as a hair dryer.

[0083] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
