Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] refer to Figures 1 to 7 This application relates to a hair styling device accessory 100. (See reference) Figure 8 It also relates to a hair styling device 1 including the hair styling device accessory 100, wherein the hair styling device accessory 100 is coupled with the main unit 200 to form the hair styling device 1.

[0041] See Figures 1 to 7 The hair styling device accessory 100 proposed in the first aspect of this application includes a fixed housing 10, a rotating clamp 20, a first motor 30, and a second motor 40.

[0042] The fixed housing 10 is used to mount or house the rotating clamp 20, the first motor 30, and the second motor 40, and is used to dock with the main unit 200. The fixed housing 10 is configured to be detachably connected to the main unit 200.

[0043] The rotating clamp 20 is mounted on the fixed housing 10 and rotates relative to the fixed housing 10. The rotating clamp 20 includes a first clamp 210 and a second clamp 220. Optionally, an elastic reset member 230 is provided between the first clamp 210 and the second clamp 220, and the first clamp 210 and the second clamp 220 have a closing tendency under the action of the elastic reset member 230. An air duct 211 is provided inside the first clamp 210, and the air duct 211 has an air inlet end 2112 and an air outlet 212. The air inlet end 2112 is located inside the fixed housing 10. The air inlet end 2112 is provided at the bottom end of the first clamp 210, and the top end of the first clamp 210 is located outside the fixed housing, for styling hair.

[0044] like Figure 3 As shown, the lower end of the rotating clamp 20 is rotatably mounted to the fixed housing 10. When the rotating clamp 20 rotates relative to the fixed housing 10, the first clamp 210 and the second clamp 220 rotate together. The first clamp 210 and the second clamp 220 are rotatably connected to each other and can open or close relative to each other. An elastic reset member 230 is disposed between the first clamp 210 and the second clamp 220. Under the elastic force of the elastic reset member 230, the first clamp 210 and the second clamp 220 tend to remain closed. In the non-use state, the first clamp 210 and the second clamp 220 remain closed. For example, the first clamp 210 and the second clamp 220 are connected by a pivot 240, and the elastic reset member 230 is a torsion spring sleeved on the pivot 240.

[0045] The first clamp 210 is provided with an air duct 211. The air inlet end 2112 of the air duct 211 is inserted into the fixed housing 10. When the fixed housing 10 is connected to the main unit 200, the airflow delivered by the main unit 200 during operation enters the air duct 211 from the air inlet end 2112 and is blown out from the air outlet 212 to style the hair. For example, refer to Figure 4 The first clamp 210 has an air outlet 212 on the side facing the second clamp 220. Further, a heating element 213 is embedded in the air outlet 212 on the side of the first clamp 210 facing the second clamp 220, and the heating element 213 heats the airflow into hot air. Optionally, the heating element 213 is a ceramic or metal component. For example, the surface of the first clamp 210 facing away from the second clamp 220 is an arc-shaped surface, and an air outlet 212 is provided circumferentially on the arc-shaped surface.

[0046] The first motor 30 drives the rotating clamp 20 to rotate relative to the fixed housing 10. In this application, the output shaft of the first motor 30 is connected to the first clamp 210. When the first motor 30 is working, it drives the first clamp 210 to rotate together with the second clamp 220. The first motor 30 can be fixedly installed at any suitable position on the fixed housing 10. Specifically, the first motor 30 is a reversible motor, so that the output shaft of the first motor 30 can rotate counterclockwise or clockwise, thereby driving the rotating clamp 20 to rotate counterclockwise or clockwise, thus achieving left-hand or right-hand hair curling.

[0047] The second motor 40 is disposed within the fixed housing 10 and is used to drive the second clamp 220 to open or close relative to the first clamp 210. The second motor 40 can drive the second clamp 220 to open relative to the first clamp 210 by rotating forward, and drive the second clamp 220 to close relative to the first clamp 210 by rotating in reverse. When an elastic reset member 230 is provided, when the second clamp 220 is closed relative to the first clamp 210, the elastic reset member 230 also serves to close the second clamp 220 relative to the first clamp 210.

[0048] After the hair styling device accessory 100 of this application is connected to the main unit 200, both the first motor 30 and the second motor 40 operate under the control of the main unit 200. When hair styling is required, the second clamp 220 opens relative to the first clamp 210 to insert hair, and then the second motor 40 resets to clamp the hair with the first clamp 210 and the second clamp 220. Afterwards, when the first motor 30 is not working, the user can straighten hair; when the first motor 30 is working, the rotating clamp 20 rotates, and the user can curl hair. By rotating the first motor 30 in opposite directions, left and right curling is automatically achieved. When in use, the hair styling device accessory 100 of this application can automatically curl hair left and right and straighten hair. Thus, the first motor 30 and the second motor 40 work together to achieve curling or straightening hair, thereby integrating the curling and straightening functions together; in addition, left and right curling can be achieved simultaneously with a single hair styling device.

[0049] refer to Figure 1 and Figure 3 In the embodiments of this application, the first motor 30 is disposed inside the fixed housing 10 and outside the air duct 211. Specifically, both the first motor 30 and the air inlet end 2112 of the air duct 211 are disposed inside the fixed housing 10. The first motor 30 and the air duct 211 are offset axially from each other, with the first motor 30 located outside the air duct 211. Thus, the first motor 30 has no effect on the air intake of the air duct 211.

[0050] Optionally, in a direction perpendicular to the rotation axis of the first clamp 210, the first motor 30 and the second motor 40 are located on opposite sides of the air inlet 2112. For example... Figure 3 As shown, in the embodiment of this application, the rotation axis of the first clamp 210 is parallel to the axial direction of the first motor 30, both being along the vertical direction. The direction perpendicular to the rotation axis of the first clamp 210 is the radial direction of the first motor 30. Figure 3 (The middle is the left and right direction). The first motor 30 and the second motor 40 are located on both sides of the air inlet 2112, which can make full use of the space inside the fixed housing 10 in the circumferential direction of the air inlet 2112.

[0051] In some embodiments, reference is made to Figure 3 , Figure 6 The fixed outer shell 10 is provided with a support ring 110, and an annular space 101 is formed between the support ring 110 and the shell wall of the fixed outer shell 10. The bottom end of the support ring 110 is connected to a base plate 120, and the base plate 120 has a grid-like structure for air passage. The air inlet end 2112 is inserted into the support ring 110 and is rotatably supported on the base plate 120. The first motor 30 and the second motor 40 are both located in the annular space 101.

[0052] The upper end of the support ring 110 is connected to the air inlet 2112, and the lower end is connected to the exhaust port of the main unit 200. The support ring 110 establishes a connection channel between the air duct 211 and the main unit 200, and also supports the rotation of the rotating clamp 20. After the fixed outer shell 10 is connected to the main unit 200, the exhaust port of the main unit 200 is connected to the air inlet 2112 through the support ring 110, thereby establishing the air inlet channel of the hair styling device 1.

[0053] The base plate 120 is mounted on the inner wall of the support ring 110. For example, the support ring 110 has an annular groove (not marked) inside, and the base plate 120 is fixed in the annular groove. At least one air passage 121 is arranged circumferentially on the base plate 120, and the air passage 121 is specifically fan-shaped but not limited thereto.

[0054] After the air inlet 2112 is supported by the base plate 120, the cavity inside the support ring 110 located below the base plate 120 communicates with the air inlet 2112 through an air channel. The cavity inside the support ring 110 located below the base plate 120 is used to communicate with the exhaust port of the main unit 200. A sealing ring is also provided between the outer peripheral wall of the air inlet 2112 and the inner wall of the support ring 110. The sealing ring is fitted and fixed on the outer peripheral wall of the air inlet 2112. During the rotation of the rotating clamp 20 relative to the fixed housing, the air inlet 2112 and the support ring 110 remain sealed, so that the airflow delivered by the main unit 200 leaks into the fixed housing 10.

[0055] The first motor 30 and the second motor 40 are located within the annular space 101, thus isolating them from the air inlet 2112 inside the support ring 110. This ensures that both the first motor 30 and the second motor 40 are located outside the air inlet channel of the hair styling device accessory 100. Specifically, the fixed housing 10 has a bottom wall 130, which connects the side wall of the fixed housing 10 to the support ring 110. Both the first motor 30 and the second motor 40 are supported by the bottom wall 130. The bottom end of the second clamp 220 is inserted into the fixed housing 10 and located outside the support ring 110. Axially, the top end of the support ring 110 is lower than the top end of the fixed housing, and the bottom ends of the second clamp 220 are all located above the top end of the support ring 110. Therefore, when the second clamp 220 opens and closes relative to the first clamp 210, it is not affected by the support ring 110.

[0056] In the embodiments of this application, the rotation of the rotating clamp 20 is supported by a support ring 110. In addition, while the support ring 110 establishes a connection channel between the air duct 211 and the host 200, it also isolates the first motor 30 outside the air inlet channel, which helps to ensure the unobstructed flow of the air inlet channel.

[0057] Furthermore, in order to ensure that the rotating clamp 20 can rotate stably, refer to Figure 3 In some embodiments, the air inlet 2112 is provided with a grille 214, which rests against the base plate 120. The hair styling device accessory 100 also includes a connector 140 connecting the grille 214 and the base plate 120, and the grille 214 is rotatably connected to the base plate 120 through the connector 140.

[0058] The grille section 214 is located at the inlet of the air inlet end 2112 and is fixedly mounted on the air inlet end 2112. Optionally, the grille section 214 and the air inlet end 2112 are integrally formed. The grille section 214 is provided with a vent 2141. After the grille section 214 and the base plate 120 are connected, the vent 2141 communicates with the air passage, and the air inlet end 2112 of the air passage 211 remains in communication with the inner cavity of the support ring 110. Optionally, the number of vents 2141 is the same as the number of air passages on the base plate 120, and the two correspond one-to-one in the axial direction of the first motor 30. Optionally, the shape of the vent 2141 is the same as the shape and size of the air passage.

[0059] In this embodiment, the grille portion 214 rests against the base plate 120; the connector 140 is fixedly connected to the base plate 120 and rotatably connected to the grille portion 214. Optionally, the connector 140 passes through the base plate 120 from below and extends into the grille portion 214; the connector 140 includes a threaded portion fixedly connected to the base plate 120 and an optical shaft portion rotatably connected to the grille portion 214. In other embodiments, the connector 140 is a bearing, and the grille portion 214 and the base plate 120 are at least partially nested, with a bearing provided at the nested joint.

[0060] In this application, by setting a base plate 120 inside the support ring 110 and setting a grille 214 at the air inlet 2112, the grille 214 and the base plate 120 are rotatably engaged, thereby providing stable support for the rotating clamp 20.

[0061] In some embodiments, reference is made to Figure 3 and Figure 4 The top of the fixed housing 10 has an opening. A flange cover 215 is provided on the outer peripheral wall of the first clamping body 210. The flange cover 215 is rotatably installed on the top of the fixed housing 10 and closes the opening. The flange cover 215 has a through hole 2151, and the second clamping body 220 passes through the through hole 2151.

[0062] The bottom end of the rotating clamp 20 is inserted into the fixed housing 10 through an opening, wherein the first clamp 210 is rotatably inserted into the support ring 110; the second clamp 220 passes through the through hole 2151, its bottom end is inserted into the fixed housing 10 and has an axial distance from the top end of the support ring 110. After the first clamp 210 is assembled into the support ring 110, the flange cover 215 is located at the top end of the fixed housing 10 and closes the opening, thereby sealing the inner cavity of the fixed housing 10 and protecting components such as the first motor 30 and the second motor 40.

[0063] In the embodiments of this application, the implementation method of the transmission connection between the output shaft of the first motor 30 and the first clamp 210 is not limited. For example, refer to... Figure 3 , Figure 5 and Figure 6 As shown, the hair styling device accessory 100 also includes a small gear 50 and a large gear 60 that mesh with each other. The small gear 50 is fixed to the output shaft of the first motor 30, and the large gear 60 is sleeved on the first clamp 210.

[0064] The first motor 30 transmits rotational power to the first clamping body 210 through a meshing pinion 50 and a gear 60. Specifically, both the gear 60 and the pinion 50 are positioned close to the inner surface of the flange cover 215, thereby avoiding the support ring 110 below.

[0065] refer to Figure 3 , Figure 6 andFigure 7 The hair styling device also includes an eccentric mechanism 70. The output shaft of the second motor 40 is connected to the second clamp 220 via the eccentric mechanism 70. Specifically, the eccentric mechanism 70 and the second motor 40 are mounted on a mounting plate 80 and fixed within the annular space 101 by the mounting plate 80. The eccentric mechanism 70 is drive-connected to the output shaft of the second motor 40. The eccentric mechanism 70 converts the rotational motion of the output shaft into the rotation of the second clamp 220 relative to the first clamp 210, thereby enabling the second clamp 220 to open and close relative to the first clamp 210.

[0066] For example, the eccentric mechanism 70 includes an eccentric wheel 710 and a transmission mechanism 720. The transmission mechanism 720 drives the output shaft of the second motor 40 and the eccentric wheel 710. The transmission mechanism 720 includes a rotating shaft, and the transmission shaft 721 is parallel to the output shaft of the second motor 40. The eccentric wheel 710 is fixed to the rotating shaft. The transmission mechanism 720 also includes at least one stage of reduction gear set, which drives the output shaft of the second motor 40 and the transmission shaft 721.

[0067] In this example, by setting the transmission mechanism 720, a suitable speed ratio can be achieved between the second motor 40 and the eccentric wheel 710; on the other hand, the position of the eccentric wheel 710 in the axial direction of the second motor 40 can be raised. Specifically, the bottom ends of the eccentric wheel 710 and the second clamping body 220 are positioned at corresponding heights in the axial direction of the second motor 40, so that the outer circumferential surface 711 of the eccentric wheel 710 can act on the second clamping body 220. Optionally, in the axial direction of the second motor 40, the bottom ends of both the eccentric wheel 710 and the second clamping body 220 are located between the support ring 110 and the large gear 60.

[0068] For example, the eccentric mechanism 70 includes an eccentric wheel 710, the rotation axis of which is parallel to the rotation axis of the first clamp 210, and the outer peripheral surface 711 of the eccentric wheel 710 abuts against the second clamp 220; the eccentric wheel 710 has a first position and a second position within its own rotation range, wherein in the first position, the eccentric wheel 710 causes the second clamp 220 to open relative to the first clamp 210, and in the second position, the second clamp 220 is closed with the first clamp 210.

[0069] In this application, the rotation axis of the eccentric wheel 710 is parallel to the rotation axis of the first clamping body 210; the rotation plane of the eccentric wheel 710 is perpendicular to the rotation axis of the first clamping body 210 and parallel to the rotation axis of the second clamping body 220 relative to the first clamping body 210. In the figure, the rotation axes of the eccentric wheel 710 and the first clamping body 210 are parallel to the drawing plane, while the rotation axis of the second clamping body 220 relative to the first clamping body 210 is perpendicular to the drawing plane.

[0070] When the eccentric wheel 710 rotates, its outer peripheral surface 711 can act on the bottom end of the second clamp 220. Furthermore, when the eccentric wheel 710 rotates within a predetermined angle range, it has a first position that allows the second clamp 220 to open relative to the first clamp 210, and a second position that allows the second clamp 220 to close relative to the first clamp 210. The outer peripheral surface 711 of the eccentric wheel 710 is, for example, a cam surface. Relative to the center of the eccentric wheel 710, the cam surface is an undulating slope. The cam surface acts on the second clamp 220 through different areas thereon, causing the second clamp 220 to open or close relative to the first clamp 210.

[0071] Please refer to Figure 8 The second aspect of this application discloses a hair styling device 1. The hair styling device 1 includes the hair styling device accessory 100 disclosed in the first aspect and a main unit 200. The main unit 200 is connected to the hair styling device accessory 100, wherein the main unit 200 is electrically connected to a first motor 30 and a second motor 40, and is used to control the operation of the first motor 30 and the second motor 40.

[0072] The hair styling device 1 of this application embodiment, through the control of the first motor 30 by the main unit 200, can automatically curl hair left and right and straighten hair. Specifically, when styling hair, the second clamp 220 opens relative to the first clamp 210 to insert hair, and then the second motor 40 resets to clamp the hair between the first clamp 210 and the second clamp 220. Afterwards, when the first motor 30 is not working, the user can straighten hair; when the first motor 30 is working, the clamp 20 rotates, and the user can curl hair. By rotating the first motor 30 in opposite directions, left and right curling is automatically achieved.

[0073] Furthermore, the host 200 includes a first control button 201 for controlling the first motor 30 and a second control button 202 for controlling the second motor 40; in response to the first control button 201 being triggered, the first motor 30 drives the rotating clamp 20 to rotate, and in response to the second control button 202 being triggered, the second motor 40 controls the second clamp 220 to open relative to the first clamp 210.

[0074] The first control button 201 and the second control button 202 are exposed on the outer surface of the main unit 200 and are connected to the control board inside the main unit 200. Using the first control button 201 and the second control button 202, the user can choose to straighten hair or curl it left or right. Specifically, the first control button 201 can be configured to switch the forward and reverse directions of the first motor 30 by repeatedly turning it on and off, or it can be configured to switch the forward and reverse directions of the first motor 30 by pressing it in different directions.

[0075] Furthermore, the hair styling device 1 also includes a hair-clamping sensor with a first clamp 210 or a second clamp 220. The hair-clamping sensor is communicatively connected to the main unit 200 and is configured to send a signal to the main unit 200 indicating that there is hair between the first clamp 210 and the second clamp 220. When hair is placed between the first clamp 210 and the second clamp 220, the hair-clamping sensor sends a signal to the main unit 200, which then controls the telescopic shaft of the second motor 40 to retract, thereby closing the first clamp 210 and the second clamp 220 to clamp the hair. The user can then choose to straighten or curl the hair; or the main unit 200 can automatically control the first motor 30 to rotate according to a preset program to curl the hair.

[0076] The type of hair-clamping sensor is not limited, as long as it can detect hair between the first clip 210 and the second clip 220. Optionally, the hair-clamping sensor is an infrared grating sensor, which is disposed on the side of the first clip 210 facing the second clip 220.

[0077] A third aspect of this application provides a control method for a hair styling device 1. (See reference...) Figure 9 The control method for the hair styling device 1 includes the following steps.

[0078] S100: Control the output shaft of the second motor 40 to rotate, so that the second clamp 220 opens relative to the first clamp 210.

[0079] S200: Control the output shaft of the second motor 40 to reset, so that the second clamp 220 and the first clamp 210 close to clamp the hair.

[0080] After the second clamp 220 and the first clamp 210 close and clamp the hair, the user can straighten the hair; or proceed with subsequent steps to curl the hair.

[0081] Furthermore, the control method for the hair styling device 1 also includes the following steps:

[0082] S300: Control the output shaft of the first motor 30 to rotate, thereby driving the second clamp 220 and the first clamp 210 to rotate and curl the hair.

[0083] S400, Control the output shaft of the first motor 30 to stop rotating.

[0084] S500: After the hair is removed from between the first clamp 210 and the second clamp 220, the output shaft of the first motor 30 is controlled to reset.

[0085] After the second clamp 220 and the first clamp 210 close and clamp the hair, the output shaft of the first motor 30 can be rotated in a predetermined direction to drive the rotating clamp 20 to rotate and perform a curling operation. At this time, either left curling or right curling can be performed.

[0086] Furthermore, S200 includes:

[0087] S210. When the hair-clamping sensor that detects whether there is hair between the second clamp 220 and the first clamp 210 is triggered, the output shaft of the second motor 40 is controlled to reset.

[0088] The hair styling device 1 uses a hair-clamping sensor to detect whether there is hair between the second clamp 220 and the first clamp 210. The hair-clamping sensor is, for example, an infrared grating sensor located on the side of the first clamp 210 facing the second clamp 220. When hair is placed between the first clamp 210 and the second clamp 220, the infrared grating sensor is triggered and sends a signal to the main unit 200. The main unit 200 can automatically control the output shaft of the second motor 40 to reset according to a preset program, thereby enabling the second clamp 220 and the first clamp 210 to clamp the hair.

[0089] Optionally, the rotation angle of the output shaft of the second motor 40 can be detected by an angle sensor, thereby enabling precise control of the reset of the output shaft of the second motor 40.

[0090] Furthermore, the S300 includes:

[0091] S310. When the hair styling device 1 is detected to be located on the left side of the head, the output shaft of the first motor 30 is controlled to rotate in a first direction.

[0092] S320. When the hair styling device 1 is detected to be located on the right side of the head, the output shaft of the first motor 30 is controlled to rotate in a second direction, wherein the second direction is opposite to the first direction.

[0093] For example, in S310 and S320, the gyroscope and image sensor can work together to identify whether the hair styling device 1 is located on the left or right side of the head, and whether it has shifted between the left and right sides. This allows for timely execution of curling operations in different directions based on the position of the hair styling device 1. Using the control method of the hair styling device of this application, the user can choose to straighten the hair or curl it in both left and right directions.
