[0008] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0010] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0011] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0012] Currently, common hair styling curling irons usually require direct contact with hair strands, using high-temperature clamping and physical winding to achieve the desired style. This requires complete manual winding, and the overall temperature of the curling iron is high, which can easily burn the skin and ears. To address this issue, a type of hair styling device based on the Coanda effect has been proposed in this field. This device uses the Coanda effect to attract and automatically wind hair, and the device itself has low heat generation requirements and is less prone to overheating. However, the user experience of this type of hair styling device is not ideal.

[0013] The reason for this is that the air outlet direction of the current hair styling device's air guide blades is fixed. When users hold the hair styling device and curl the hair on the left and right sides respectively, they can only get hair styles with the same curling direction. In order to ensure that the hair styles on the left and right sides are symmetrical, users usually need to hold the hair styling device in an extremely awkward way, which leads to a decline in user experience.

[0014] In view of this, the present invention provides a hair styling device that, by setting adjustable air guide vanes, can change the direction of the air outlet, thereby meeting the user's needs in different usage scenarios and at least improving the problem of poor user experience of current hair styling devices.

[0015] To facilitate understanding of the hair styling device provided by the present invention, it will be described below in conjunction with the accompanying drawings, wherein... Figure 1 This is a three-dimensional structural diagram of an embodiment of the hair styling device provided by the present invention; Figure 2 for Figure 1 Exploded view of the hair styling device; Figure 3 for Figure 2 A magnified structural diagram of part A in the middle; Figure 4 for Figure 1 A schematic diagram of the main structure of the hair styling device; Figure 5 for Figure 4Schematic diagram of the structure of the mid-section BB; Figure 6 for Figure 4 A schematic diagram of the structure of the hair styling device (excluding the windshield); Figure 7 for Figure 6 Schematic diagram of the structure of the mid-section CC; Figure 8 for Figure 6 Schematic diagram of the structure of the mid-section DD; Figure 9 for Figure 6 A schematic diagram of the structure of the EE in mid-section.

[0016] Please see Figures 1 to 3 In one embodiment of the present invention, the hair styling device 100 includes a mounting bracket 1, a plurality of air guide blades 2, and a driving assembly 3; the mounting bracket 1 extends along a first direction X; the plurality of air guide blades 2 are arranged around the periphery of the mounting bracket 1, the plurality of air guide blades 2 surround each other and define an air blower cavity on the inner side, and an air outlet 2a is defined between two adjacent air guide blades 2, the air guide blades 2 are configured to rotate about the axis of the first direction X, and adjust the orientation of the air outlet 2a; the driving assembly 3 is disposed on the mounting bracket 1, and the driving assembly 3 is configured to drive the plurality of air guide blades 2 to rotate synchronously.

[0017] "The mounting bracket 1 extends along the first direction X" means that the length direction of the mounting bracket 1 is the first direction X, and when the mounting bracket 1 is a rotating body structure, the axial direction of the mounting bracket 1 is the first direction X.

[0018] Regarding "multiple air guide blades 2 surround each other and define a blower cavity on the inner side", the blower cavity is connected to multiple air guide outlets 2a. The blower cavity is used to introduce blowing airflow, and the blowing airflow can be discharged from the air guide outlets 2a. Based on the Coanda effect, the discharged blowing airflow can form a negative pressure adsorption effect on the surface of the air guide blades 2, thereby adsorbing hair.

[0019] "The air outlet 2a is defined between two adjacent air guide blades 2" can be understood as follows: the two adjacent air guide blades 2 are positioned with their front and rear ends facing each other in the circumferential direction of the mounting bracket 1, and an air outlet 2a is defined between them. During the rotation of the air guide blades 2, the angle between the front end of one air guide blade 2 and the rear end of the other air guide blade 2 changes, thereby changing the size and orientation of the air outlet 2a. For ease of understanding, the air outlet 2a is defined between the front end of the first air guide blade 2 and the rear end of the second air guide blade 2. For example, in the projection of the first direction X, the orientation of the air outlet 2a is originally counterclockwise, and the front end of the first air guide blade 2 is in an upward position relative to the rear end of the second air guide blade 2. By rotating the air guide blades 2 counterclockwise, the front end of the first air guide blade 2 can be relatively lowered, and the rear end of the second air guide blade 2 can be relatively raised, thereby adjusting the orientation of the air outlet 2a to clockwise.

[0020] The phrase "the guide vane 2 rotates around the axis of the first direction X" can be understood as follows: the first end of the guide vane 2 rotates around the axis of the first direction X, the tail end of the guide vane 2 rotates around the axis of the first direction X, and the middle part of the guide vane 2 rotates around the axis of the first direction X.

[0021] In the technical solution provided by this invention, multiple air guide blades 2 are arranged around the periphery of the mounting bracket 1, and an air outlet 2a is defined between two adjacent air guide blades 2. Based on this, the air guide blades 2 are configured to rotate along the axis of the first direction X, so that the orientation of two adjacent air guide blades 2 changes, that is, the orientation of the air outlet 2a defined between them changes. The orientation of the air outlet 2a can be switched freely between clockwise and counterclockwise around the first direction X. The direction in which the hair is wrapped around the multiple air guide blades 2 can be changed according to the user's actual usage needs. For example, after the user uses their right hand to style the hair on the left side clockwise, they can adjust the orientation of the air outlet 2a by using the drive component 3, and then use their left hand to style the hair on the right side counterclockwise, ensuring that the hair styling on both sides is symmetrical and the process is relatively smooth, thus improving the user experience.

[0022] Please see Figure 2 In one embodiment, the air guide blade 2 includes a blade body 21 and a rotating connection portion 22; the blade body 21 extends circumferentially along the mounting bracket 1 and has two air guide ends 211 in the circumferential direction; the rotating connection portion 22 is disposed on the inner side of the blade body 21 and between the two air guide ends 211, and the rotating connection portion 22 is rotatably connected to the mounting bracket 1; wherein, an air guide opening is defined between the two air guide ends 211 of two adjacent blade bodies 21 that are close to each other.

[0023] In conjunction with the above embodiments, the two air guide ends 211 of the blade body 21 are the first and last ends of the air guide blade 2; the "rotational connection part 22" can be a rotational connection protrusion or a rotational connection hole.

[0024] In the above technical solution, since the rotating connection part 22 is located on the inner side of the blade body 21 and between the two air guide ends 211, the air guide blade 2 is rotatably connected to the mounting bracket 1 by means of the rotating connection part 22, which is equivalent to the middle part of the air guide blade 2 being rotatably connected to the mounting bracket 1. During the rotation of the air guide blade 2, the two air guide ends 211 can be raised and lowered respectively. Under the cooperative action of the two adjacent air guide blades 2, the direction of the air guide opening can be changed with a small rotation range.

[0025] Please see Figure 2 and Figure 3In one embodiment, the mounting bracket 1 includes two mounting portions 11, which are located at both ends of the blower cavity in the first direction X. The mounting portions 11 are provided with a plurality of rotating mating portions 112 distributed circumferentially. The blade body 21 is provided with rotating connecting portions 22 at both ends in the first direction X. The two rotating connecting portions 22 of the blade body 21 are respectively rotatably connected to the corresponding rotating mating portions 112 on the two mounting portions 11.

[0026] The number of multiple rotating mating parts 112 on the mounting part 11 is usually equal to the number of multiple air guide blades 2, and the distribution positions of the multiple rotating mating parts 112 on the two mounting parts 11 should coincide in the projection of the first direction X, so as to ensure that the two rotating mating parts 112 that coincide in the projection of the first direction X can be responsible for the rotating installation of one air guide blade 2.

[0027] In the above technical solution, the two mounting parts 11 are located at both ends of the blower cavity in the first direction X, and each mounting part 11 is provided with a plurality of rotating mating parts 112. Based on this, the blade body 21 is also provided with rotating connecting parts 22 at both ends of the first direction X. Through the rotating connection between the two rotating connecting parts 22 and the corresponding two rotating mating parts 112, the air guide blade 2 can be provided with an installation foundation at both ends of the first direction X, ensuring that its installation is firm and stable.

[0028] Please see Figure 4 and Figure 5 In one embodiment, the mounting bracket 1 further includes two windproof covers 12, which are respectively disposed on two mounting portions 11; the two ends of the blade body 21 extend into the two windproof covers 12 respectively.

[0029] The "windshield 12" typically has an open end and an inner cavity, and the blade body 21 at the end in the first direction X can extend into its inner cavity from the open end of the windshield 12.

[0030] In the above technical solution, by setting wind deflectors 12 at both ends of the blade body 21, the wind deflectors 12 can block both ends of the blower cavity along the first direction X. At the same time, the two wind deflectors 12 extend into both ends of the blade body 21, thereby limiting the exhaust position of the blower airflow to the air outlet 2a, reducing airflow loss and improving the curling efficiency. In addition, the wind deflectors 12 can also provide limiting protection for the air guide blade 2, preventing hair strands from getting stuck in the air outlet 2a from the end of the air guide blade 2.

[0031] Specifically, please refer to Figure 5The inner wall of the windshield cover 12 is provided with a stepped surface, and the end of the air guide blade 2 is provided with a sealing protrusion. The sealing protrusion extends into the inner side of the windshield cover 12, and makes the end face of the air guide blade 2 face the stepped surface, so as to increase the relative area between the air guide blade 2 and the windshield cover 12, increase the air outlet path, that is, increase the air outlet resistance, and enhance the air leakage prevention effect of the windshield cover 12.

[0032] Please see Figure 6 , Figure 7 and Figure 9 In one embodiment, the drive assembly 3 includes two drive wheels 31 and a linkage shaft 32. The two drive wheels 31 are rotatably mounted on two mounting portions 11 along the axis of the first direction X. Multiple push protrusions 311 are provided on the periphery of the drive wheels 31, and the multiple push protrusions 311 abut against the inner surfaces of multiple blade bodies 21. The linkage shaft 32 extends along the first direction X, and its two ends are connected to the two drive wheels 31. Within the rotational stroke of the drive wheels 31, the push protrusions 311 are configured to push one of the air guide ends 211 of the blade body 21 away from the center of the mounting portion 11, so that the other air guide end 211 is close to the center of the mounting portion 11.

[0033] "The center of the mounting part 11" refers to the center of the mounting part 11 projected in the first direction X; "the drive wheel 31 is rotatably mounted on the mounting part 11 along the axis of the first direction X" means that the drive axis of the drive wheel 31 coincides with the central axis of the mounting part 11, that is, coincides with the central axis of the plurality of guide vanes 2.

[0034] In the above technical solution, the drive wheel 31 is provided with a plurality of pushing protrusions 311 on its periphery. The plurality of pushing protrusions 311 abut against the inner surfaces of the plurality of blade bodies 21 respectively. During the rotation stroke of the drive wheel 31, the plurality of pushing protrusions 311 can push the plurality of blade bodies 21 to move, thereby causing one of the air guide ends 211 of the blade body 21 to move away from the center of the mounting part 11, so that the other air guide end 211 moves closer to the center of the mounting part 11, thereby changing the orientation of the air guide outlet 2a. This drive solution has fewer structural components, lower cost and higher reliability.

[0035] In other embodiments, the drive assembly 3 may also include a drive gear and a plurality of driven gears. The plurality of driven gears are respectively mounted on the rotating connection portion 22 of the plurality of guide vanes 2. The drive gear meshes with the plurality of driven gears at the same time. Under the rotation of the drive gear, the plurality of driven gears can drive the plurality of guide vanes 2 to rotate synchronously.

[0036] Please see Figure 2 and Figure 5In one embodiment, a plurality of first reinforcing ribs 212 are provided on the inner side of the blade body 21. The plurality of first reinforcing ribs 212 extend along the circumferential direction and are arranged at intervals along the first direction X. The plurality of first reinforcing ribs 212 include two first end reinforcing ribs 212a at the end positions. Two rotating connecting parts 22 of the blade body 21 are respectively provided on the two first end reinforcing ribs 212a. The two mounting parts 11 are located between the two first end reinforcing ribs 212a.

[0037] Considering that the function of the guide vane 2 is to guide the airflow direction, the guide end 211 of the blade body 21 usually needs to bear a large load. In the above technical solution, multiple first reinforcing ribs 212 are provided on the inner side of the blade body 21, which can improve the strength of the blade body 21 along the circumferential direction of the mounting bracket 1, so that the blade body 21 can be designed to be relatively thin. On this basis, a rotating connection part 22 is provided on the first end reinforcing rib 212a, and the two mounting parts 11 are located between the two first end reinforcing ribs 212a, which reduces the occupation of the first end reinforcing rib 212a on the internal space of the blower cavity and ensures the airflow of the guide outlet 2a at the first direction X end.

[0038] Please see Figure 3 and Figure 7 In one embodiment, one of the drive wheels 31 is configured as an active drive wheel 31a, and the active drive wheel 31a is provided with a snap-fit ​​protrusion 312; the mounting part 11 is provided with a plurality of snap-fit ​​grooves 111, and the plurality of snap-fit ​​grooves 111 are distributed circumferentially; within the rotation stroke of the active drive wheel 31a, the snap-fit ​​protrusion 312 can sequentially snap into the plurality of snap-fit ​​grooves 111 to fix the opening orientation of the air guide outlet 2a.

[0039] The snap-fit ​​protrusion 312 can be set to protrude toward the central axis of the mounting part 11. At this time, the opening direction of the plurality of snap-fit ​​grooves 111 is opposite to the central axis of the mounting part 11. Of course, the snap-fit ​​protrusion 312 can also be set toward the first direction X. Correspondingly, the opening direction of the plurality of snap-fit ​​grooves 111 is set toward the opposite direction of the snap-fit ​​protrusion 312.

[0040] In the above technical solution, during the rotation of the active drive wheel 31a, the locking protrusion 312 selectively engages with the locking groove 111 through interference, thereby achieving the positioning of the active drive wheel 31a relative to the mounting part 11, so that the air guide blade 2 is kept in the corresponding position and the air guide outlet 2a is kept in the corresponding orientation, thereby stably performing the air guiding function.

[0041] Multiple snap-fit ​​grooves 111 can be used to position the air outlet 2a to the counterclockwise and clockwise extreme air outlet directions respectively. The airflow is ejected from the air outlet 2a, flows over the windward side of the outer side of the blade body 21, and flows over the top side of the outer side of the blade body 21 in sequence through the Coanda effect, and reaches the leeward side of the outer side of the blade body 21, where it merges with the airflow ejected from the next air outlet 2a. All the airflows are connected end to end to form a cyclone, thereby achieving the effect of curling hair.

[0042] Please see Figure 5 In one specific embodiment, the active drive wheel 31a is detachably connected to the corresponding windshield cover 12. At the same time, the corresponding windshield cover 12 is also connected to the linkage shaft 32. By turning the windshield cover 12, the active drive wheel 31a can be rotated and the linkage shaft 32 can be rotated, thereby driving the two drive wheels 31 to rotate, and finally driving the multiple guide vanes 2 to rotate.

[0043] Please see Figure 3 and Figure 7 In one embodiment, the active drive wheel 31a is provided with a limiting groove 313, which extends circumferentially, and the mounting part 11 is provided with a limiting protrusion 113, which extends into the limiting groove 313. Within the active stroke of the active drive wheel 31a, the two circumferentially opposite sidewalls of the limiting groove 313 can respectively abut against the limiting protrusion 113 to prevent the pushing protrusion 311 from disengaging from the air guide end 211 of the blade body 21.

[0044] "The two side walls of the limiting groove 313 that are opposite each other along the circumferential direction can respectively abut against the limiting protrusion 113" means that the two side walls of the limiting groove 313 abut against the limiting protrusion 113 respectively, which means that the active drive wheel 31a reaches the limit position in the clockwise and counterclockwise rotation directions respectively.

[0045] In the above technical solution, the mutual cooperation between the limiting groove 313 and the limiting protrusion 113 can limit the active stroke of the active drive wheel 31a, which helps to reduce the probability of the push protrusion 311 detaching from the blade body 21 due to excessive rotation of the active drive wheel 31a, and improves the reliability of the hair styling device 100.

[0046] Please see Figure 2 and Figure 8In one embodiment, the mounting bracket 1 further includes connecting ribs 13 that connect the two mounting portions 11. Multiple connecting ribs 13 are arranged circumferentially. The connecting ribs 13 are arranged corresponding to two air guide ends 211 that are close to each other. An elastic contact portion 131 is provided on the side of the connecting rib facing the air guide end 211. The elastic contact portion 131 is configured to be abutted by one of the air guide ends 211 to limit the orientation of the air guide outlet 2a. Within the rotation stroke of the active drive wheel 31a, the air guide end 211 can abut against the elastic contact portion 131 to varying degrees.

[0047] Since the connecting rib 13 is set to correspond to two air guide ends 211 that are close to each other, that is, the connecting rib 13 is set to correspond to the air guide outlet 2a, at the same time, between the two adjacent air guide blades 2 corresponding to the connecting rib 13, only one of the air guide ends 211 abuts against the elastic contact part 131 set on the connecting rib 13, and the air guide end 211 of the air guide blade 2 is in a raised state relative to the connecting rib 13.

[0048] In the above technical solution, multiple connecting ribs 13 are provided between the two mounting parts 11. This not only ensures that the relative positions of the two mounting parts 11 are fixed, but also allows the connecting ribs 13 to correspond to the positions of the air outlet 2a. Furthermore, the connecting ribs 13 can be used as a base to set up the elastic contact part 131. The air guide end 211 can abut against the elastic contact part 131 to different degrees. This means that the elastic contact part 131 can provide a base for the air guide end 211 of the air guide blade 2 when the snap-fit ​​protrusion 312 snaps into different snap-fit ​​grooves 111. This, in turn, cooperates with the push protrusion 311 to fix the position of the air guide blade 2.

[0049] In one embodiment, the plurality of snap-fit ​​grooves 111 include a first snap-fit ​​groove, a second snap-fit ​​groove, a third snap-fit ​​groove, and a fourth snap-fit ​​groove distributed sequentially along the circumference of the mounting bracket 1. The first snap-fit ​​groove and the fourth snap-fit ​​groove correspond to the clockwise limit air outlet direction and the counterclockwise limit air outlet direction of the air guide outlet 2a, respectively. The second snap-fit ​​groove and the third snap-fit ​​groove 111 correspond to the clockwise gentle air outlet direction and the counterclockwise gentle air outlet direction of the air guide outlet 2a, respectively. The width of the air guide outlet 2a in the limit air outlet direction is smaller than the width in the gentle air outlet direction. For example, the width of the air guide outlet 2a in the limit air outlet direction is 0.5 mm, and the width in the gentle air outlet direction is 1 mm, thereby achieving an adjustable air outlet effect.

[0050] In the above technical solution, increasing the width of the air outlet 2a increases the air volume, thereby increasing the amount of hair curled. At the same time, it increases the heating amount, prolongs the curling time, and improves the curling effect. Under the same airflow speed, increasing the width of the air outlet 2a results in a larger air volume. Similarly, under the same air volume, increasing the width of the air outlet 2a results in a smaller airflow speed, requiring less power and consuming less energy, which can save energy and protect the environment to a certain extent.

[0051] Please see Figure 2 and Figure 8 In one embodiment, a second reinforcing rib 213 is provided on the inner side of the blade body 21, and the second reinforcing rib 213 extends along the first direction X; a plurality of third reinforcing ribs 14 are provided between two adjacent connecting ribs 13, and the plurality of third reinforcing ribs 14 are distributed along the first direction X, and a clearance groove 141 is provided on the third reinforcing rib 14 corresponding to the position of the second reinforcing rib 213, which extends into the clearance groove 141.

[0052] In the above technical solution, a second reinforcing rib 213 is provided on the inner side of the blade body 21. Since the second reinforcing rib 213 extends along the first direction X, it can improve the structural strength of the blade body 21 in the first direction X. In addition, a plurality of third reinforcing ribs 14 are provided between two adjacent connecting ribs 13. The plurality of third reinforcing ribs 14 are distributed along the first direction X, which can improve the overall structural strength of the mounting bracket 1. On this basis, a clearance groove 141 is provided on the third reinforcing rib 14 corresponding to the position of the second reinforcing rib 213 and extending along the first direction X. The clearance groove 141 can provide room for the second reinforcing rib 213 provided on the blade body 21, making the structure of the hair styling device 100 more compact.

[0053] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
