[0104] The following describes the specific implementation manners of the present disclosure with reference to the accompanying drawings.

[0105] In this article, "upper", "lower", "front", "rear", "left", "right", etc. are only used to represent the relative positional relationships between relevant parts, rather than defining the absolute positions of these relevant parts.

[0106] In this article, "first", "second", etc. are only used for distinguishing each other, rather than indicating importance, order, and the prerequisite for mutual existence, etc.

[0107] In this text, terms such as "equal" and "identical" are not strict mathematical and / or geometric limitations, and also include tolerances that can be understood by those skilled in the art and are allowed in manufacturing or use, etc.

[0108] In an embodiment of the present application, a hair dryer is provided, including: a body, an air outlet assembly, and a rotary joint assembly. The air outlet assembly includes a first air outlet member and a second air outlet member, and the second air outlet member is configured to rotate relative to the body; the air ducts in the first air outlet member, the second air outlet member, and the body are communicated with each other through the rotary joint assembly, and the air outlet assembly and the body are rotatably connected through the rotary joint assembly.

[0109] The hair dryer provided in the embodiment of the present application includes a body, an air outlet assembly, and a rotary joint assembly. The air outlet assembly includes a first air outlet member and a second air outlet member. The air ducts in the first air outlet member, the second air outlet member, and the body are all communicated with each other through the rotary joint assembly, and the second air outlet member is rotatably connected to the body through the rotary joint assembly. In this way, through a single rotary joint assembly, the functions of communicating the air duct between the fan assembly and the body and rotating the air outlet assembly on the body can be realized simultaneously. The structure is simple, and the purpose of adjusting the blowing direction and blowing range of the hair dryer is achieved, improving the uniformity and blowing efficiency of the hair dryer.

[0110] For the sake of easy understanding, hereinafter, with reference to Figures 1 to 18 a specific structure and its working principle of the hair dryer provided in the embodiment of the present application will be described in detail in conjunction with an embodiment.

[0111] In some related technologies, a vertical hair dryer is configured to have two air outlets, and the two air outlets can blow in different directions. Although this solution can blow to different positions of the user's hair. However, the structural form of this vertical hair dryer imitates the human head, and the two air outlets are relatively fixed and non-adjustable, which results in that on the one hand, the blowing angle of the hair dryer is limited, and on the other hand, when the hair dryer is idle, this shape occupies a large space volume and is not easy to store. In addition, if the air outlet is designed to be adjustable in angle, problems such as how to connect the air duct while realizing rotation will be faced.

[0112] To solve the above problems, as Figures 1 to 4As shown, a hair dryer provided in one embodiment of the present application includes: a body 10 and an air outlet assembly 20. The body 10 may include a support frame 11 and a host assembly 12. The support frame 11 can support the entire hair dryer on the surface of an object such as the ground or a wall, so that the user does not need to hold the hair dryer, freeing the user's hands. The host assembly 12 may include a host component for forming wind, for example, the host assembly 12 may include a housing 121, a control mainboard, a first air duct component 122, a filter assembly 123, a motor assembly 124, and a heating module 125, etc., wherein the control mainboard, the first air duct component 122, the filter assembly 123, the motor assembly 124, and the heating module 125, etc. may be accommodated inside the housing 121, the first air duct component 122 has an air inlet and an air outlet, the motor assembly 124 is used to form wind inside the first air duct component 122, the filter assembly 123 filters the air entering the motor assembly 124, which can filter out dust in the air and prevent the user's hair from being drawn into the motor, thereby protecting the motor assembly 124 and the user's hair; the heating module 125 can heat the wind in the first air duct component 122 to form hot wind. Of course, it can be understood that the body 10 is not limited to this.

[0113] The air outlet assembly 20 is used to blow air toward a target area, where the target area refers to an area where the user's head can be accommodated when the user uses the hair dryer.

[0114] In one embodiment of the present application, the air outlet assembly 20 is constructed into at least two parts: a first air outlet member 21 and a second air outlet member 22. The first air outlet member 21 is provided with a first air outlet surface 21A, and the second air outlet member 22 is provided with a second air outlet surface 22A. Air outlets are respectively provided on the first air outlet surface 21A and the second air outlet surface 22A for blowing air onto the user's hair.

[0115] The hair dryer of the present application further includes a rotary joint assembly, wherein the first air outlet member 21, the second air outlet member 22 and the air duct in the body 10 are connected to each other through the rotary joint assembly, and the second air outlet member 22 is rotatably connected to the body 10 through the rotary joint assembly. In this way, the air duct connection between the fan assembly 20 and the body 10 and the rotation of the air outlet assembly 20 on the body 10 can be achieved simultaneously through one rotary joint assembly, and the structure is simple.

[0116] In one embodiment of the present application, the first outlet surface 21A of the first outlet member 21 and the second outlet surface 22A of the second outlet member 22 are configured to blow air to different positions of the target area. In other words, the first outlet surface 21A of the first outlet member 21 and the second outlet surface 22A of the second outlet member 22 blow air to different positions of the user's hair respectively. For example, the first outlet member 21 may be configured to blow air to the top of the user's hair; the second outlet member 22 may be configured to blow air to the side of the user's hair. However, this is not limited to this.

[0117] In one embodiment of the present application, the second air outlet member 22 rotates relative to the body 10. Specifically, in one embodiment, the first air outlet member 21 is rotatably connected to the body 10 and is configured to rotate relative to the body 10 along the first axis X. That is, the first axis X is the rotation axis of the first air outlet member relative to the body 10; the second air outlet member 22 is configured to move at least partially around the target area as the first air outlet member 21 rotates, so as to blow air to different positions in the circumferential direction towards the target area. In this way, as the first air outlet member 21 rotates along the first axis X on the body 10, the first air outlet member 21 will drive the second air outlet member 22 to rotate synchronously, and the second air outlet member 22 is configured to at least partially surround the target area in the circumferential direction when rotating with the first air outlet member 21. Therefore, the first air outlet member 21 and the second air outlet member 22 can surround the user's hair in the target area and blow air to different positions, thereby achieving the purpose of adjustable blowing angle and blowing range of the hair dryer, and improving the blowing uniformity and blowing efficiency.

[0118] In one embodiment of the present application, when the first air outlet member 21 rotates relative to the body 10 along the first axis X, the first air outlet surface 21A can blow air around the user's top hair in the horizontal direction; the second air outlet member 22 can blow air around the user's side hair in the circumferential direction.

[0119] In one embodiment of the present application, please refer to Figure 1 、 Figure 5 and Figure 9 As shown, the second air outlet member 22 is configured to be rotatably connected to the first air outlet member 21 and is configured to rotate relative to the first air outlet member 21 along the second axis Y. That is, the second axis Y is the rotation axis of the second air outlet member 22 relative to the first air outlet member 21, and the first axis X is perpendicular to the second axis Y. In this way, the second air outlet member 22 can also rotate relative to the first air outlet member 21 along the second axis Y. The second air outlet member 22 rotates relative to the first air outlet member 21 to present different forms between the two. When the hair dryer is idle, the second air outlet member 22 can rotate relative to the first air outlet member 21 to a regular shape that is convenient for storage; when the hair dryer is in use, the second air outlet member 22 can rotate relative to the first air outlet member 21 to form an angle between the two, so as to facilitate blowing air to different positions on the user's head.

[0120] In addition, in the above solution, the second air outlet member 22 can rotate relative to the first air outlet member 21, and can also adjust the angle between the first air outlet member 21 and the second air outlet member 22 according to the head shapes and sizes of different users, so as to adapt to various user head shapes and improve the hair drying effect.

[0121] In one embodiment of the present application, as shown in Figure 5As shown, the host component 12 may include a housing 121, a control main board, a first air duct member 122, a fan blade 123, a fan blade drive motor 124, a heating module 125, etc. Among them, the control main board, the first air duct member 122, the fan blade 123, the fan blade drive motor 124, the heating module 125, etc. may be accommodated inside the housing 121. The first air duct member 122 has an air inlet and an air outlet. The fan blade 123 can form wind inside the first air duct member 122 under the drive of the fan blade drive motor 124, and the heating module 125 can heat the wind in the first air duct member 122 to form hot air. Of course, it can be understood that the host component 12 is not limited to this.

[0122] In an embodiment of the present application, as Figure 6 shown, second air duct members are respectively provided inside the first air outlet member 21 and the second air outlet member 22. For the convenience of description, the components forming the air duct inside the first air outlet member 21 are denoted as the first sub-air duct member 211, and the second air duct member inside the second air outlet member 22 is denoted as the second sub-air duct member 212. Among them, the first air duct member 122, the first sub-air duct member 211, and the second sub-air duct member 212 are respectively provided with an air inlet and an air outlet, and the first air duct member 122 can be respectively communicated with the air inlets of the first sub-air duct member 211 and the second sub-air duct member 212 through its air outlet.

[0123] In an embodiment of the present application, when the second fan assembly 22 is configured to be rotatably connected to the first air outlet member 21 along the second axis Y, the first air outlet member 21 and the body 10, and the second air outlet member 22 and the first air outlet member 21 can be rotatably connected through a rotary joint assembly. In other words, the three air ducts of the first air duct member 122, the first sub-air duct member 211, and the second sub-air duct member 212 can be communicated with each other through the rotary joint assembly, and the first air outlet member 21 and the host component 12 can be rotatably connected through the rotary joint assembly, and the second air outlet member 22 and the first air outlet member 21 can be rotatably connected through the rotary joint assembly. In this way, through the rotary joint assembly, while the air outlet assembly 20 can perform a rotating action, the communication of the air ducts can be realized, and the structure is simple and the assembly is convenient.

[0124] Denote the air outlet of the first air duct member 122 as the first air outlet 122a, the air inlet of the first sub-air duct member 211 as the first air inlet, and the air inlet of the second sub-air duct member 212 as the second air inlet. In an embodiment of the present application, as Figure 6 、 Figures 10 to 18As shown in the figure, the rotary joint assembly includes: a tee joint 281. The tee joint 281 is provided with an air inlet joint 281A, a first air outlet joint 281B, and a second air outlet joint 281C that communicate with each other and are perpendicular to each other axially. Among them, the air inlet joint 281A and the first air outlet 122a are coaxially docked, and the axes of the air inlet joint 281A and the first air outlet 122a extend along the first axis X. The air inlet joint 281A is rotatably connected to the first air outlet 122a. The first air outlet joint 281B is coaxially docked to the first air inlet, and the second air outlet joint 281C is rotatably connected to the second air inlet, and the axis of the second air outlet joint 281C extends along the second axis.

[0125] In this way, the three joints on the tee joint 281 are respectively connected to the first air duct member 122, the first sub-air duct member 211, and the second sub-air duct member 212 to realize the air duct connection function, and the rotation function of the first air outlet member 21 and the second air outlet member 22 is realized by the rotation docking of the joints with the air inlets and air outlets.

[0126] In an embodiment of the present application, as Figure 6 shown, the rotary joint assembly further includes: a swivel joint 282 and a rotary bearing 283. The swivel joint 282 is connected to the first air outlet 122a, and the swivel joint 282 is configured to be inserted into the air inlet joint 281A; the rotary bearing 283 is provided between the swivel joint 282 and the air inlet joint 281A to enable the swivel joint 282 and the air inlet joint 281A to rotate relative to each other.

[0127] In an embodiment of the present application, as Figure 6 and Figure 14 shown, the hair dryer may further include: a driving member 291 and a transmission member 292. The driving member 291 may be selected as a motor or the like; the transmission member 292 is configured to be drivingly connected between the driving member 291 and the tee joint 281, and under the drive of the driving member 291, the transmission member 292 can drive the tee joint 281 to rotate relative to the first air outlet 122a.

[0128] In an embodiment of the present application, as Figure 5 and Figure 14 shown, the transmission member 292 includes: a first gear 292A and a second gear 292B. The first gear 292A is connected to the output shaft of the driving motor to rotate when the output shaft rotates; the second gear 292B is meshed with the first gear 292A, and the second gear 292B is configured to be coaxially connected to the first air inlet joint 281A to drive the first air inlet joint 281A to rotate when the first gear 292A rotates.

[0129] In this way, through the gear transmission method, the purpose that the first air outlet member 21 rotates relative to the main machine assembly 12 along the first axis X can be achieved. It can be understood that in other embodiments not shown, the driving member 291 and the transmission member 292 can also be configured as other structures, which are not limited thereto.

[0130] In an embodiment of the present application, the diameter of the first gear 292A is smaller than the diameter of the second gear 292B. In this way, on the one hand, it is easier to precisely control the rotation angle of the first air outlet member 21; on the other hand, the first gear 292A can be accommodated in the housing 121 of the main machine assembly 12, with a smaller size, less occupied space, and a more compact structure.

[0131] In an embodiment of the present application, as Figure 6 and Figure 7 shown, at least one of the first air outlet 122a and the adapter 282 and the air inlet adapter 281A is further provided with a seal 293 therebetween. By providing the seal 293, the sealing performance of the air duct docking position can be improved, the sealing problem brought about by the relative rotation of the first air outlet member 21 and the second air outlet member 22 of the hair dryer relative to the main machine assembly 12 can be solved, so that the wind force is concentrated and blown out from the air outlet, ensuring that there is no gas leakage during the rotation process.

[0132] In an embodiment of the present application, as Figure 7 shown, the seal 293 can be configured as a sealing ring, and its cross-section is generally in the shape of a trapezoidal groove 293A, and the bottom end of the trapezoidal groove 293A is narrower and the notch end is wider. The sealing ring is configured to be deformable under extrusion, and its notch end can be deformed and enlarged, so that the notch end can be expanded to cover the sealing gap, thereby forming a structure similar to an umbrella valve to achieve a good sealing effect. It can be understood that the specific structure of the seal 293 is not limited thereto.

[0133] In an embodiment of the present application, the second air outlet adapter 281C and the second air inlet are configured to be in frictional fit, so that the rotation angle of the second air outlet member 22 relative to the second air outlet member 22 can be locked. Specifically, friction surfaces that can cooperate with each other can be respectively provided or fixedly connected to the second air outlet adapter 281C and the second air inlet to achieve the purpose of frictional fit therebetween.

[0134] In an embodiment of the present application, as Figure 8 shown, a limiting stop member 23 is provided on the second air outlet member 22. The limiting stop member 23 is configured to move synchronously with the second air outlet member 22 along the second axis Y, and when the second air outlet member 22 and the first air outlet member 21 are at a preset angle, the limiting stop member 23 can abut against the second air outlet member 22. The preset angle can be the maximum rotation angle of the second air outlet member 22 relative to the first air outlet member 21 along the second axis Y.

[0135] In an embodiment of the present application, as Figure 8 shown, the limiting stop member 23 can be configured to be located at the hinged position of the second air outlet member 22 and the first air outlet member 21, and the limiting stop member 23 can be configured as any suitable structure such as a stop block. It can be understood that the specific arrangement position and structure of the limiting stop member 23 are not limited thereto.

[0136] In an embodiment of the present application, as Figure 9 shown, the second air outlet member 22 is configured to be rotatable along the second axis Y to make the second air outlet surface 22A coplanar with the first air outlet surface 21A. Thus, in some application scenarios, the first air outlet surface 21A and the second air outlet surface 22A are arranged coplanarly. In other words, the first air outlet surface 21A can be arranged parallel to the second air outlet surface 22A, so that the second air outlet member 22 and the first air outlet member 21 can blow air to the user's head or side simultaneously in the same direction. Moreover, when the hair dryer needs to be stored in a non-working state, the first air outlet surface 21A and the second air outlet surface 22A are arranged coplanarly. Compared with the case where the first air outlet surface 21A and the second air outlet surface 22A are arranged at an obtuse angle, the overall volume is smaller and the occupied space is smaller. Therefore, after the hair dryer is used, the second air outlet member 22 can be rotated to make the first air outlet surface 21A and the second air outlet surface 22A coplanar, so as to reduce the volume of the blowing assembly and fold the complex shape into a simple conventional shape to occupy the smallest space for storage.

[0137] In an embodiment of the present application, please refer to Figure 6 and Figure 8 shown, a connecting member 24 can be provided on the second air outlet member 22, and the connecting member 24 is configured to move synchronously with the rotation of the second air outlet member 22. A connecting adapter 25 can be provided on the body 10, and the connecting adapter 25 and the connecting member 24 can be combined or separated from each other. When the connecting member 24 moves to make the second air outlet surface 22A coplanar with the first air outlet surface 21A, the connecting member 24 and the connecting adapter 25 are combined with each other. In this way, in the case where the first air outlet surface 21A and the second air outlet surface 22A are coplanar, the current state of the first air outlet member 21 and the second air outlet member 22 can be locked through the cooperation of the connecting member 24 and the connecting adapter 25. On the one hand, when the hair dryer is in the state where the first air outlet surface 21A and the second air outlet surface 22A are coplanar, it can prevent the second air outlet member 22 from accidentally falling off during the working process of the hair dryer; on the other hand, since the shape of the hair dryer is more regular when the first air outlet surface 21A and the second air outlet surface 22A are coplanar and the occupied space for storage is small, the second air outlet member 22 can be prevented from shaking or rotating during storage.

[0138] In one embodiment of the present application, one of the connector 24 and the connector adapter 25 may be configured as a magnet, and the other may be configured as a magnet or iron. However, this is not limited to this. The connector 24 and the connector adapter 25 may also be combined or separated by a snap-on connection or the like.

[0139] In one embodiment of the present application, the second air outlet member 22 is configured to rotate frictionally with the first air outlet member 21, so that the rotation angle of the first air outlet member 21 relative to the second air outlet member 22 can be locked under the action of friction. In this way, when the user uses the hair dryer, when the user manually pulls or electrically drives the second air outlet member 22 to rotate along the second axis Y relative to the first air outlet member 21 to any suitable angle, the angle can be locked by the friction force.

[0140] Therefore, in one embodiment of the present application, Figure 16 As shown, the hair dryer may further include: a wet-dryness detection component 30 provided on at least one of the first air outlet 21 and the second air outlet 22, the wet-dryness detection component 30 being configured to detect wet-dryness information of the object being blown, and an air volume control component 40 provided on at least one of the first air outlet 21 and the second air outlet 22, the air volume control component 40 being configured to control the blowing air volume of the first air outlet 21 and / or the second air outlet 22; the host component is configured to control the blowing air volume of the first air outlet 21 and / or the blowing air volume of the second air outlet 22 based on preset parameters. The preset parameters may be the wet-dryness information detected by the wet-dryness detection component 30, or may be the control parameters stored in advance. In this way, during the blowing process, the hair dryer may adjust the air volume of the first air outlet 21 and the second air outlet 22 according to the wet-dryness state of the user's hair.

[0141] In some scenarios, during the use of the hair dryer, the first air outlet member 21 can blow towards the top of the user's head, and the second air outlet member 22 can blow towards the side of the user's head such as the back of the head. When starting to dry the hair, the air can be blown out from the first air outlet member 21 and the second air outlet member 22 simultaneously. Usually, the hair volume on the top of the user's head is less, so the hair on the top of the head will be dried first. However, due to the larger hair volume at the back of the head and other positions, it will be more difficult to dry. Therefore, if the hair on the top of the user's head has been dried, but the hair at the back of the head and other positions has not been dried, if the air volume of the first air outlet member 21 is not adjusted and the hair on the top of the head is continuously blown, the hot air will cause a poor user experience and continuously damage the hair. Therefore, in the hair dryer in an embodiment of the present application, when the hair on the top of the head is dried, the air volume of the first air outlet member 21 can be adjusted through the air volume control component 40 to reduce the air volume at the top of the head. Moreover, the first air duct member 122 is configured to divide the air into two parts and distribute it to the first air outlet member 21 and the second air outlet member 22. When the air volume in the first air duct member 122 remains unchanged, if the air volume of the first air outlet member 21 is reduced, the air volume of the corresponding second air outlet member 22 will increase. Thus, the hair at the back of the head can be dried faster.

[0142] In some other application scenarios, for short-haired users, they more expect the air volume to be closer to the top of the head. The air volume of the first air outlet member 21 can be controlled to increase, while the air volume of the second air outlet member 22 is reduced by adjusting the air volume of at least one of the first air outlet member 21 and the second air outlet member 22, so as to dry the hair of short-haired users faster.

[0143] In an embodiment of the present application, as Figure 16 , 17A shown in FIGS. 17A to 17E, the air volume control component 40 includes: a blocking member 41 and a moving driving member 42. The blocking member 41 is configured to be reciprocally movably disposed at the air inlet of the first air outlet member 21 and / or the air inlet of the second air outlet member 22 to block or open the corresponding air inlet; the moving driving member 42 is connected to the blocking member 41 and is configured to drive the blocking member 41 to reciprocally move. In this way, by driving the blocking member 41 to reciprocally move through the moving driving member 42 to block or open the corresponding air inlet, the air volume adjustment of the first air outlet member 21 and the second air outlet member 22 is realized.

[0144] In an embodiment of the present application, the air volume control component 40 can be disposed on the first air outlet member 21 and is located at the first air inlet of the first sub-air duct member 211. Since the first air duct member 122 is respectively connected to the first air inlet of the first sub-air duct member 211 and the second air inlet of the second sub-air duct member 212 through the adapter 282 assembly, the air volume control component 40 disposed at the first air inlet can achieve the purpose of simultaneously adjusting the air volumes of the first air outlet member 21 and the second air outlet member 22. It should be understood that the air volume control component 40 can also be disposed at the second air inlet of the second air duct member.

[0145] It should be noted that the blocking member 41 can be implemented by any suitable structure such as a push rod, a baffle, a plug head, etc. Please refer to Figures 17A to 17C As shown, the moving driving member 42 can be implemented by a crank - connecting rod mechanism to achieve the purpose of moving the blocking member 41; as Figure 17E shown, the moving driving member 42 can also adopt a rack - and - pinion mechanism to achieve the purpose of moving the blocking member 41; as Figure 17D shown, the moving driving member 42 can be implemented by a hinge driving mechanism to achieve the purpose of moving the blocking member 41. Of course, it can be understood that the specific structure of the moving driving member 42 is not limited herein.

[0146] In an embodiment of the present application, as Figure 1 and Figure 3 shown, the first air outlet surface 21A of the first air outlet member 21 is configured to be perpendicular to the first axis X, and the second air outlet member 22 is configured to be rotatable along the second axis Y to make the second air outlet surface 22A arranged at an angle with the first air outlet surface 21A.

[0147] In this way, in some application scenarios, the first air outlet member 21 and the second air outlet member 22 can be arranged at an angle to blow to different positions of the user's head. For example, the first air outlet member 21 can be configured such that the first air outlet surface 21A extends to cover at least a partial area of the user's top hair, and the second air outlet member 22 can be configured such that the second air outlet surface 22A is configured to extend to cover at least a partial area of the user's side hair.

[0148] It should be noted that when the second air outlet member 22 rotates relative to the first air outlet member 21, the driving method can be manual operation driving or electric driving.

[0149] In an embodiment of the present application, during the hair - drying process, the second air outlet member 22 can be manually toggled according to the user's head shape to apply a force to the second air outlet member 22, so that the second air outlet member 22 rotates to an angle adapted to the user's head shape. Figure 3 and Figure 4 shown is a schematic diagram of a state of the hair - dryer during the working process. As Figure 3 and Figure 4 shown, the first air outlet member 21 can blow air to the user's top hair from top to bottom, and the second air outlet member 22 can blow air to the user's side hair obliquely downward or horizontally.

[0150] In an embodiment of the present application, as Figure 3 and Figure 4As shown, the first air outlet surface 21A is configured to be arranged at an obtuse angle with the second air outlet surface 22A, so that the first air outlet surface 21A and the second air outlet surface 22A enclose a non-closed target area. Thus, in some application scenarios, the second air outlet member 22 can be rotated to make the first air outlet surface 21A and the second air outlet surface 22A form an obtuse angle, which is more convenient for the user's head to be placed in the target area and more in line with the user's air blowing direction requirements when blowing hair. It can be understood that in other embodiments, the second air outlet member 22 can also be rotated to make the first air outlet surface 21A and the second air outlet surface 22A form a right angle or an acute angle arrangement.

[0151] In an embodiment of the present application, as shown in FIG. 1, the body 10 includes a support frame 11 and a main machine assembly 12 disposed on the top of the support frame 11, and the first air outlet member 21 is rotatably connected to the main machine assembly 12. Thus, the hair dryer can be configured as a vertical hair dryer. However, the specific structure of the body 10 is not limited thereto.

[0152] In an embodiment of the present application, as Figure 5 shown, the extending direction of the first air outlet member 21 is configured to be consistent with the extending direction of the main machine assembly 12, the first axis X is configured to be perpendicular to the first air outlet surface 21A, and the second air outlet member 22 is configured to rotate relative to the first air outlet member 21 to make the extending direction of the second air outlet member 22 consistent with the extending direction of the main machine assembly 12. Thus, the main machine assembly 12 and the air outlet assembly 20 of this hair dryer can occupy the smallest space at this time, which is convenient for storage.

[0153] In an embodiment of the present application, as Figure 5 shown, the main machine assembly 12 is configured to be rotatable relative to the support frame 11 and at least rotated to be parallel to or angled with the support frame 11. Among them, when the main machine assembly 12 is parallel to the support frame 11, the hair dryer is folded, occupying a small space and being conducive to storage; when the main machine assembly 12 is angled with the support frame 11, it is convenient for using the hair dryer.

[0154] It should be noted that the rotatability of the main machine assembly 12 relative to the support frame 11 is not only limited to realizing the folding or opening of the hair dryer, but also the included angle between the main machine assembly 12 and the support frame 11 can be locked at different angles through a locking structure to adapt to different scenarios. For example, when the user lies flat or semi-reclines to blow hair, the first air outlet surface 21A can form an angle with the horizontal plane; when the user sits to blow hair, the first air outlet surface 21A can be arranged horizontally. However, it is not limited thereto. The locking structure can be realized by means of frictional fit, etc.

[0155] In an embodiment of the present application, as Figure 1As shown, the support frame 11 may include a base 111 and a telescopic rod 112. By adjusting the length of the telescopic rod 112, the height of the blowing component can be adjusted to adapt to different users. The specific structure of the telescopic rod 112 is not limited herein.

[0156] In an embodiment of the present application, as Figure 6 shown, in the direction perpendicular to the first axis X and the second axis Y (i.e., the Z-axis direction), the first air outlet member 21 and the second air outlet member 22 are respectively located on opposite sides of the first axis X, and the second axis Y intersects the first axis X.

[0157] In another embodiment of the present application, as Figure 15 shown, in the direction perpendicular to the first axis X and the second axis Y, the first air outlet member 21 and the second air outlet member 22 are respectively located on opposite sides of the first axis X, and the second axis Y deviates from the first axis X towards the side away from the first air outlet member 21, so that during the rotation of the second air outlet member 22 along the second axis Y, it is not easy to touch the user's head.

[0158] In an embodiment of the present application, the distance range by which the second axis Y deviates from the first axis X towards the side away from the first air outlet member 21 is 20 mm to 60 mm. In this way, when the user uses the hair dryer of the present application, during the rotation of the second air outlet member 22 along the second axis Y, it is not easy to touch the user's head, thereby effectively improving the user experience.

[0159] Furthermore, in an embodiment of the present application, the distance by which the second axis Y deviates from the first axis X towards the side away from the first air outlet member 21 is 40 mm. At this time, it can not only ensure that during the rotation of the second air outlet member 22 along the second axis Y, it is not easy to touch the user's head, but also make the contours of the first air outlet member 21 and the second air outlet member 22 better fit the contour of the user's head, improving the blowing effect. Taking the direction perpendicular to the first axis X and the second axis Y as the front-rear direction, the first air outlet member 21 is denoted as the front air outlet assembly, and the second air outlet member 22 is denoted as the rear air outlet assembly. In this embodiment, the second axis Y deviates backward from the first axis X. In this way, when the user's head is placed in the target area surrounded by the front air outlet assembly and the rear air outlet assembly, when the rear air outlet assembly rotates relative to the front air outlet assembly along the second axis Y, the rotation position can be biased backward and away from the user's head to avoid interference between the rotation of the rear air outlet assembly and the user's head.

[0160] In an embodiment of the present application, please refer to Figure 5 and Figure 8As shown in the figure, the air outlet assembly 20 further includes: a swing blade member 26 and a swing driving member 27. The swing blade member 26 is disposed at the first air outlet surface 21A and / or the second air outlet surface 22A, and is configured to include a plurality of swingable blades; the swing driving member 27 is connected to the swing blade member 26 and is configured to drive the blades to swing. In this way, by providing swingable swing blades at the first air outlet surface 21A and the second air outlet surface 22A, it is more conducive to the uniformity of the blown air.

[0161] Figure 8 The figure shows a schematic structural view of the air outlet of the first air outlet member 21 and the second air outlet member 22. In an embodiment of the present application, as Figure 8 shown, the air outlets of the first air outlet member 21 and the second air outlet member 22 can be configured as two long strip-shaped air outlet channels. By adding a plurality of swingable blades at the air outlets to disperse the air outlet area. By the swing of the blades, the blown air can be made softer and blown to a larger area, rather than concentrated in a certain area. Especially for long hair, the swingable blades can better send the air to the end area of the hair. The swing driving member 27 can be configured to drive the blades to swing by a manual operation method or an electric driving method. The specific structure of the swing blade driving member is not limited herein.

[0162] In an embodiment of the present application, as Figures 1 to 4 shown, the first air outlet member 21 and the second air outlet member 22 can be located directly below the main machine assembly 12, and the first air outlet surface 21A is located below the first air outlet member 21. When the first air outlet surface 21A and the second air outlet surface 22A are coplanar, the second air outlet surface 22A is located directly below the second air outlet member 22. In this way, the air on the first air outlet surface 21A can blow downward towards the user's head. It can be understood that the air outlet assembly 20 is not limited to being disposed directly below the main machine assembly 12, and can also be located on the side of the main machine assembly 12 and other positions.

[0163] As Figure 6 shown, the present application further provides an air outlet assembly. The air outlet assembly 20 is provided with an air inlet duct and an air outlet duct. The air outlet duct includes a first air outlet duct and a second air outlet duct; the second air outlet duct is configured to rotate relative to the body 10, and a motor is provided on the body. The extending direction of the first air outlet duct is configured to be parallel to the axis A of the motor. It can be understood that, as Figure 6As shown, the air outlet assembly 20 includes a first air outlet member 21 and a second air outlet member 22. A three-way joint 281 is provided on the air outlet assembly 20. A first air outlet duct is formed inside the first air outlet member 21, and a second air outlet duct is formed inside the second air outlet member 22. For the first air outlet member 21 and the second air outlet member 22, the three-way joint 281 is provided with an air inlet joint 281A, a first air outlet joint 281B, and a second air outlet joint 281C that communicate with each other and are perpendicular to each other axially. The first air outlet joint 281B communicates with the first air outlet duct, and the second air outlet joint 281C communicates with the second air outlet duct. In this way, when there is an angle between the first air outlet member 21 and the second air outlet member 22, the air entering from the air inlet duct can be split into the first air outlet duct and the second air outlet duct. The motor can be the motor assembly 124. Since the extending direction of the first air outlet duct is parallel to the axis A of the motor, and the second air outlet duct is configured to rotate relative to the body 10, the air outlet assembly 20 where the first air outlet duct is located can be fitted to the body 10, thereby saving some space.

[0164] Further, as Figure 9 shown, in an embodiment of the present disclosure, the second air outlet duct is configured to rotate relative to the body 10 to be parallel to the axis A of the motor. In this way, the entire air outlet assembly 20 can be rotated to fit onto the body 10, thereby facilitating the storage of the air outlet assembly 20.

[0165] As Figure 6 shown, in an embodiment of the present application, the first air outlet member 21 is configured to be rotatably connected to the body 10 relative to the body 10 along a first axis X; the second air outlet member 22 is configured to be rotatably connected to the first air outlet member 21 along a second axis Y, and the first axis X is perpendicular to the second axis Y; wherein, both between the first air outlet member 21 and the body 10 and between the second air outlet member 22 and the first air outlet member 21 are rotatably connected. In this way, the function of the air outlet assembly 20 rotating on the body 10 can be realized, the structure is simple, and the purpose of adjustable blowing direction and blowing range of the hair dryer is achieved, improving the uniformity and blowing efficiency of the hair dryer.

[0166] Further, as Figure 6 shown, in an embodiment of the present application, in the direction perpendicular to the first axis X and the second axis Y, the first air outlet member 21 and the second air outlet member 22 are respectively located on opposite sides of the first axis X; the first axis X intersects the second axis Y. In this way, the overall length of the air outlet assembly 20 is effectively saved. As Figure 15 shown, in another embodiment of the present application, the second axis Y deviates from the first axis X to the side away from the first air outlet member 21, so that when the second air outlet member 22 rotates along the second axis Y, it is not easy to touch the user's head.

[0167] As Figure 6As shown in the figure, the present application also provides an air outlet assembly 20, which includes a first air outlet member 21 and a second air outlet member 22. The first air outlet surface 21A of the first air outlet member 21 and the second air outlet surface 22A of the second air outlet member 22 are configured to blow towards the target area. The first air outlet member 21 is rotatably connected to the body 10 and is configured to rotate relative to the body 10 along the first axis X. The second air outlet member 22 is configured to move at least partially around the target area as the first air outlet member 21 rotates, so as to blow towards the target area in the circumferential direction. When the air outlet assembly 20 of the present disclosure is used for blowing hair, the first air outlet member 21 can be rotated along the first axis X. At this time, the second air outlet member 22 rotates synchronously as the first air outlet member 21 rotates on the body 10, so as to surround the user's head in the circumferential direction and blow the air towards the hair until the hair at each position of the user is dried.

[0168] Application Scenario 1

[0169] As Figures 1 to 4 and Figure 6 As shown in the figure, a hair dryer provided in this application scenario includes: a body 10, an air outlet assembly 20 and a rotary joint assembly. The air outlet assembly 20 includes a first air outlet member 21 and a second air outlet member 22. The first air outlet surface 21A of the first air outlet member 21 and the second air outlet surface 22A of the second air outlet member 22 are configured to blow towards different positions of the target area, and the second air outlet member 22 is configured to rotate relative to the body 10. The air ducts among the first air outlet member 21, the second air outlet member 22 and the body 10 are communicated with each other through the rotary joint assembly, and the second air outlet member 22 is rotatably connected to the body 10 through the rotary joint assembly.

[0170] During the use of the hair dryer, the second air outlet member 22 can be rotated. At this time, the second air outlet member 22 rotates on the body 10 and blows the air towards different positions of the hair until the hair at each position of the user is dried. Among them, during the rotation of the second air outlet member 22, the air ducts of the body 10, the first air outlet member 21 and the second air outlet member 22 are communicated through the rotary joint assembly, and the second air outlet member 22 realizes rotation on the body 10 through this rotary joint assembly.

[0171] Application Scenario 2

[0172] As Figure 6 As shown in the figure, the present application provides an air outlet assembly. The air outlet assembly 20 is provided with an air inlet duct and an air outlet duct. The air outlet duct includes a first air outlet duct and a second air outlet duct. The second air outlet duct is configured to rotate relative to the body 10, and a motor is provided on the body 10. The extending direction of the first air outlet duct is configured to be parallel to the axis A of the motor.

[0173] As Figure 3As shown, when the user has short hair or medium-length hair, the extending direction of the first air outlet duct is parallel to the axis of the motor, and the extending direction of the second air outlet duct rotates to be not parallel to the axis of the motor. In this way, it is convenient to dry the hair on the top of the user's head and at the back of the head simultaneously.

[0174] When the user has long hair, Figure 3 When the air outlet assembly is in the state shown in drying the hair on the top of the user's head and at the back of the head, there may be a situation where the middle and ends of the user's hair are not yet dry. At this time, the state of the air outlet assembly can be changed to Figure 9 the state shown, where the extending directions of both air outlet ducts are parallel to the axis of the motor. The user can lie on the sofa or lie prone to blow dry the middle and end parts of the hair.

[0175] The above has described the embodiments of the present disclosure. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the disclosed embodiments. The scope of the present disclosure is defined by the appended claims.
