[0002] When using a hair dryer to dry or style hair, users often install hair styling devices (such as diffusers or nozzles) at the air outlet to improve the drying or styling effect. In related technologies, this type of hair styling device often has multiple air outlets and a mechanical airflow regulation mechanism with valves or baffles installed inside. By driving the valves or baffles to rotate, some air outlets are opened and others are closed, thus regulating the airflow and its output position.

[0003] However, during the actual research and development process, the inventors discovered that this structure, which only uses valve plates or baffles to change the air volume and output position, easily generates eddies in the air duct during the process of adjusting the air volume and output position.

[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0053] Please refer to the following: Figures 1 to 11The adjustable airflow hair styling device 100 provided in this application embodiment will now be described. The adjustable airflow hair styling device 100 includes: a main body shell 10, an adjustment nest 20, and an inner core 30.

[0054] The main body shell 10 has at least an air inlet 11, an air outlet A12, and an air outlet B13; the adjusting nest 20 and the inner core 30 are movably disposed within the main body shell 10. The adjusting nest 20 and the main body shell 10 enclose a main air duct 15 and an auxiliary air duct 16. The main air duct 15 is connected to the air outlet A12, and the auxiliary air duct 16 is connected to the air outlet B13. The inner core 30 includes a plurality of air plates 31 arranged in a circular array. When the adjusting nest 20 moves, it can drive the plurality of air plates 31 to move along an involute trajectory so that the main air duct 15 and / or the auxiliary air duct 16 are connected to the air inlet 11.

[0055] Specifically, the adjustment nest 20 is set up, and the adjustment nest 20 surrounds the main air duct 15 and the auxiliary air duct 16; when the adjustment nest 20 is driven to move, it can drive multiple air plates 31 to move in an involute trajectory, thereby connecting the main air duct 15 and the auxiliary air duct 16, and realizing the control of the blowing state of the air outlet A12 and the air outlet B13; due to the setting of the main air duct 15 and the auxiliary air duct 16, the airflow can be divided, which can improve the stability of the airflow, make it less likely to generate airflow vortices, and reduce the noise of the hair styling device.

[0056] In some embodiments, the main body shell 10 has an air outlet 103 on the front side, and both the air outlet A12 and the air outlet B13 penetrate the front and rear surfaces of the air outlet 103; the front surface of the adjusting nest 20 is provided with a first ring body 21 and a second ring body 22, the first ring body 21 is smaller than the second ring body 22 and is located inside the second ring body 22; the first ring body 21 abuts against the rear surface of the air outlet 103 and forms the main air duct 15, and the second ring body 22 abuts against the rear surface of the air outlet 103 and forms the auxiliary air duct 16.

[0057] Specifically, there are multiple air outlets A12 and B13. The multiple air outlets A12 are set according to the position of the main air duct 15 so that the airflow in the main air duct 15 can be blown out from the air outlets A12. The multiple air outlets B13 are set according to the position of the auxiliary air duct 16 so that the airflow in the auxiliary air duct 16 can be blown out from the air outlets B13.

[0058] It is understandable that the main air duct 15 and the auxiliary air duct 16 are formed by the first ring body 21 and the second ring body 22, so that the auxiliary air duct 16 is arranged outside the main air duct 15; therefore, multiple air outlets B13 are located outside multiple air outlets A12, so that the airflow of the main air duct 15 can be blown outward from the air outlets A12, and the airflow of the auxiliary air duct 16 can be blown outward from the air outlets B13.

[0059] It should be noted that the cross-section of the air outlet 103 is circular, and multiple air outlets A12 are located at the center of the air outlet 103 and can be arranged in multiple rows from the inside to the outside. Each row of air outlets A12 is arranged in a circular array. The air outlets B13 are arranged in multiple rows from the outside of the outermost air outlet A12 to the outside. Each air outlet B13 is arranged in a circular array.

[0060] More specifically, the main air duct 15 extends rearward through the rear surface of the adjusting nest 20, making the main air duct 15 conductively connected to the air inlet 11; the first ring body 21 is provided with an air passage window 23, which conductively connects the auxiliary air duct 16 and the main air duct 15. The rear surface of the air outlet 103 is provided with a first cover plate 19, which extends rearward and overlaps with the first ring body 21; when the adjusting nest 20 moves and the air passage window 23 enters the area where the first cover plate 19 is located, the first cover plate 19 can cover the air passage window 23 to close the conductive connection between the main air duct 15 and the auxiliary air duct 16.

[0061] Furthermore, the cross-section of the adjusting nest 20 is circular, and the adjusting nest 20 is rotatably installed inside the main housing. The adjusting nest 20 and the inner core 30 are stacked one after the other, and multiple air plates 31 can surround the main control air passage 313. The main control air passage 313 can connect the main air duct 15 and the air outlet. When the adjusting nest 20 moves, it can drive multiple air plates 31 to move along an involute trajectory to change the cross-sectional size of the main control air passage 313.

[0062] Specifically, the adjustment nest 20 can be rotated to achieve multi-level adjustment. For example, when the adjustment nest 20 is rotated to the first level, the main control air passage 313 of the multiple air plates 31 can be simultaneously adjusted to the first diameter; and the air passage window 23 is covered by the first cover plate 19, so that the airflow enters the main air duct 15 through the air inlet 11 and the main control air passage 313 and blows forward from the air outlet A12. When the drive adjustment nest 20 is rotated to the second position, it can simultaneously drive the main control air passage 313 of the multiple air plates 31 to adjust to the second diameter, which is larger than the first diameter, thereby increasing the air intake of the main air duct 15. At the same time, the air passage window 23 rotates synchronously with the adjustment nest 20 and exits the area where the first cover plate 19 is located, so that the auxiliary air duct 16 can be connected to the main air duct 15 through the air passage window 23, allowing part of the airflow of the main air duct 15 to enter the auxiliary air duct 16, achieving the effect of diversion. In the second position, airflow enters both the main air duct 15 and the auxiliary air duct 16, and this airflow can be discharged simultaneously from the air outlet A12 and the air outlet B13.

[0063] Therefore, in the first setting, only air outlet A12 can be controlled; in the second setting, both air outlets A12 and B13 can be controlled, thus changing the user's desired air outlet location. During the transition from the first to the second setting, the main air duct 15 is not shut off; instead, a portion of the airflow within the main duct 15 is diverted to the auxiliary air duct 16. This improves airflow volume and stability, resulting in smoother airflow. Furthermore, no eddies are generated when switching between different settings, reducing noise and improving airflow efficiency.

[0064] In other embodiments, the second ring body 22 and the inner peripheral side of the main body shell 10 form an extended air duct 18, and the adjusting nest 20 is provided with an extended air vent 24 that penetrates its front and rear surfaces. The extended air vent 24 can be connected to the extended air duct 18 and the air inlet 11. The main body shell 10 also includes an air outlet C14, which is connected to the extended air duct 18.

[0065] Specifically, there are multiple air outlets C14, arranged in a circular array to form a row, and arranged at intervals from the inside to the outside of the outermost air outlet B13; so that the air outlet 103 gradually arranges multiple air outlets A12, B13 and C14 outward from its center position. When the drive adjustment nest 20 is rotated to the first position, it can be controlled to control air to be discharged from only air outlet A12; when the drive adjustment nest 20 is rotated to the second position, it can control air to be discharged from air outlets A12 and B13; when the drive adjustment nest 20 is rotated to the third position, it can control air to be discharged from air outlets A12, B13 and C14.

[0066] It is understandable that during the process of switching the adjustment nest 20 from the first gear to the second gear, and during the process of switching the second gear to the third gear, since the adjustment nest 20 rotates in a rotating manner, the effect of stepless adjustment of the airflow can be achieved by gradually driving the rotation of the adjustment nest 20.

[0067] More specifically, each air panel 31 is provided with an extended air control through hole 314, which penetrates the front and rear surfaces of the air panel 31; the extended air duct 18 can be connected to the air inlet 11 through the extended air outlet 24 and the extended air control through hole 314.

[0068] For example, when the rotating adjustment nest 20 moves to the first stroke, the adjustment nest 20 is in the first position; multiple air plates 31 move along the involute trajectory to adjust the main control air passage 313 to the first diameter, and allow the air inlet 11 to be connected to the main air duct 15 through the main control air passage 313; the air passage window 23 moves synchronously with the rotation of the adjustment nest 20, enters the area where the first cover plate 19 is located, and allows the first cover plate 19 to cover the air passage window 23, closing the connection between the main air duct 15 and the auxiliary air duct 16; the air plate 31 closes the expansion air outlet 24, and closes the connection between the air inlet 11 and the expansion air duct 18 through the air plate 31; at this time, the airflow entering from the air inlet 11 flows out to the air outlet A12 only through the main air duct 15.

[0069] When the rotating adjustment nest 20 moves to the second stroke, the adjustment nest 20 is in the second position. Multiple air vanes 31 move along the involute trajectory to adjust the main control air passage 313 to the second diameter, which is larger than the first diameter, and allow the air inlet 11 to be connected to the main air duct 15 through the main control air passage 313. At the same time, the air window 23 moves out of the area where the first cover plate 19 is located as the adjustment nest 20 rotates, allowing the auxiliary air duct 16 to be connected to the main air duct 15 through the air window 23. The air vane 31 closes the expansion air outlet 24, and closes the connection between the air inlet 11 and the expansion air duct 18. At this time, part of the airflow entering from the air inlet 11 can flow out from the air outlet A12, and part of the airflow enters the auxiliary air duct 16 and flows out from the air outlet B13.

[0070] When the rotating adjustment nest 20 moves to the third stroke, the adjustment nest 20 is in the third position, and multiple air vanes 31 move along an involute trajectory, so that the extended air control passage 314 of the air vane 31 is connected to the extended air outlet 24; at the same time, the air window 23 moves out of the area where the first cover plate 19 is located as the adjustment nest 20 rotates, so that the auxiliary air duct 16 is connected to the main air duct 15 through the air window 23; at this time, the airflow entering from the air inlet 11 can enter the extended air duct 18 through the extended air control passage 314 and the extended air outlet 24 and flow out from the air outlet C14, the airflow can enter the main air duct 15 through the main air control passage 313 and flow out from the air outlet A12, and part of the airflow entering the main air duct 15 enters the auxiliary air duct 16 and flows out from the air outlet B13.

[0071] In some embodiments, the main housing 10 includes a front housing 101 and a rear housing 102 assembled together. An air outlet 103 is disposed on the front surface of the front housing 101, and an air inlet 11 is disposed on the rear housing 102. A clearance notch 104 is provided between the front housing 101 and the rear housing 102. An actuating protrusion 25 is provided on the outer side of the adjusting nest 20, and the actuating protrusion 25 is exposed on the outer side of the main housing 10 through the clearance notch 104. A gear groove 106 is provided on the outer side of the front housing 101 and / or the rear housing 102, and the actuating protrusion 25 is provided with a plurality of gear protrusions 251 for the gear groove 106 to be inserted.

[0072] Preferably, there are two actuating protrusions 25, which are located on the outer side of the adjusting nest 20 and spaced apart. The user drives the adjusting nest 20 to rotate by actuating the two actuating protrusions 25, which can improve the smoothness of the rotation of the adjusting nest 20 and effectively prevent the adjusting nest 20 from getting stuck during rotation.

[0073] It should be noted that the assembly of the front shell 101 and the rear shell 102 can be carried out by any of the following methods: screw fastening, snap-fit ​​installation, adhesive fixing, or welding fixing.

[0074] It is understandable that the gear position groove 106 is set according to the number of gears; for example, if there are three gears, there are three gear position grooves 106, and when the gear position protrusion 251 is inserted into a gear position groove 106, a gear can be triggered. At the same time, the gear position protrusion 251 and the gear position groove 106 can be switched between the main body housing 10 and the toggle protrusion 25; the gear position groove 106 can also be used by using two gear position protrusions 251 to surround the gear position groove 106.

[0075] Specifically, the front surface of the air plate 31 is provided with a first pivot protrusion 311, and the rear surface of the adjusting nest 20 is provided with a first involute-shaped limiting groove 26 for the first pivot protrusion 311 to be inserted; the rear shell 102 is provided with a second involute-shaped limiting groove 105, and the rear surface of the air plate 31 is provided with a limiting protrusion 312 that can be slidably installed in the second involute-shaped limiting groove 105. When the adjusting nest 20 is rotated, it can drive multiple air plates 31 to move along the extension direction of the first involute-shaped limiting groove 26 and the second involute-shaped limiting groove 105, so that the multiple air plates 31 can adjust the different diameters of the main control air passage 313, and can also control the conductive connection between the expansion control air passage 314 and the expansion air outlet 24 through the movement of the multiple air plates 31, or close the expansion air outlet 24 through the movement of the multiple air plates 31.

[0076] In other embodiments, the front housing 101 has multiple mounting slots 107 on the rear surface of the air outlet 103. The mounting slots 107 are used for the movable insertion of the front ends of the first ring body 21 and the second ring body 22. The mounting slots 107 improve the rotational reliability of the adjustment nest 20 and reduce air leakage between the various air ducts, thereby improving the reliability of the hair styling device in controlling the airflow from different air outlets. The rear housing 102 has a plug-in part for inserting into the air outlet of the hair dryer to install the hair styling device on the hair dryer and provide airflow through the hair dryer.

[0077] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
