Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] refer to Figures 1 to 7 This application relates to a hair styling tool 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.

[0040] See Figures 1 to 7The first aspect of this application proposes a hair styling accessory 100, which includes a fixed base 10, a rotating clamp 20, a rotating motor 30, and an opening and closing motor 40.

[0041] The fixed base 10 is used to mount or accommodate the rotating clamp 20, the rotating motor 30, and the opening and closing motor 40, and is used to dock with the main unit 200. The fixed base 10 is configured to be detachably connected to the main unit 200.

[0042] The rotating clamp 20 is mounted on the fixed base 10 and rotates relative to the fixed base 10. The rotating clamp 20 includes a first clamp 210 and a second clamp 220 that can open or close. 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 close 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 2111 and an air outlet 212.

[0043] refer to Figure 1 and Figure 3 As shown, the lower end of the rotating clamp 20 can be rotatably mounted to the fixed base 10. When the rotating clamp 20 rotates relative to the fixed base 10, the first clamp 210 and the second clamp 220 rotate together. The first clamp 210 and the second clamp 220 are rotatably connected together 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. And 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.

[0044] refer to Figure 3 and Figure 4 The first clamp 210 is provided with an air duct 211. The air inlet end 2111 of the air duct 211 is inserted into the fixed base 10. When the fixed base 10 is connected to the main unit 200, the airflow delivered by the main unit 200 enters the air duct 211 from the air inlet end 2111 and is blown out from the air outlet 212 to style the hair. For example, the side of the first clamp 210 facing the second clamp 220 is provided with an air outlet 212. 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 part or a metal part. 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 on the arc-shaped surface along the circumferential direction.

[0045] A rotary motor 30 is used to drive the rotating clamp 20 to rotate relative to the fixed base 10. In this application, the stator 310 of the rotary motor 30 is fixed to the fixed base 10, and the rotor 320 of the rotary motor 30 is connected to the first clamp 210 to drive the rotating clamp 20 to rotate relative to the fixed base 10. In the embodiments of this application, the rotary motor 30 is specifically a forward and reverse rotating motor to drive the rotating clamp 20 to rotate in different directions. The rotary motor 30 can be an external rotor 320 motor or an internal rotor 320 motor. By integrating the rotor 320 with the first clamp 210, when the rotor 320 rotates relative to the stator 310, the rotor 320 drives the entire rotating clamp 20 to rotate together.

[0046] The opening and closing motor 40 is used to drive the first clamp 210 and the second clamp 220 of the rotating clamp 20 to open and close, so as to clamp hair. The opening and closing motor 40 is disposed in the fixed base 10, and is used to drive the second clamp 220 to open or close relative to the first clamp 210. The opening and closing 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. In other embodiments, the opening and closing motor 40 may also be mounted on the rotating clamp 20, specifically on the first clamp 210.

[0047] The hair styling accessory 100 of this application, after docking with the main unit 200, has both the rotary motor 30 and the opening / closing motor 40 operating under the control of the main unit 200. When hair styling is required, the opening / closing motor 40 drives the first clamp 210 and the second clamp 220 of the rotating clamp 20 to open to insert hair, and then closes the first clamp 210 and the second clamp 220 to clamp the hair. Afterwards, when the rotary motor 30 is not working, the user can straighten hair; when the rotary motor 30 is working, the rotating clamp 20 rotates, and the user can curl hair. By rotating the rotary motor 30 in opposite directions, left and right curling is automatically achieved. Therefore, the hair styling accessory 100 of this application can automatically curl hair left and right and straighten hair during use.

[0048] The rotary motor 30 and the opening / closing motor 40 work together to achieve either curling or straightening of hair, thus integrating the curling and straightening functions together. In addition, a single hair styling tool can simultaneously curl hair to the left and right. Furthermore, the rotary motor 30 is integrated into the first clamp 210, which occupies little radial space, has a simple structure, and eliminates the need for additional transmission components when curling hair.

[0049] In some embodiments, reference is made to Figure 3 , Figure 5 and Figure 6 The fixed base 10 includes a first fixed shell 110 and a second fixed shell 120. The first fixed shell 110 is sleeved on the second fixed shell 120, and a receiving cavity 101 is formed between the two. The rotary motor 30 is located in the receiving cavity 101. The air inlet end 2111 is rotatably connected to the second fixed shell 120, and the inner cavity of the second fixed shell 120 is connected to the air duct 211.

[0050] In this embodiment, the rotary motor 30 is specifically an external rotor 320 motor. The rotor 320 of the rotary motor 30 is located around the stator 310. The stator 310 is sleeved and fixed on the second fixed housing 120. The rotor 320 is connected to the rotating clamp 20. The second fixed housing 120 is configured to dock with the main unit 200, and the inner cavity of the second fixed housing 120 connects the air inlet 2111 of the ventilation duct 211 with the air outlet of the main unit 200. Through the inner cavity of the second fixed housing 120, the air inlet 2111 of the ventilation duct 211 and the air outlet (not shown) of the main unit 200 are connected axially in the rotary motor 30, establishing a complete airflow channel.

[0051] In this embodiment, the fixed base 10 is composed of a first fixed shell 110 and a second fixed shell 120, which facilitates molding and manufacturing. The second fixed shell 120 serves as a load-bearing component of the stator 310 of the rotary motor 30 and a connector for docking with the main unit 200. It is also connected to the air inlet 2111 of the ventilation duct 211 and the air outlet of the main unit 200, providing a simple and compact design.

[0052] refer to Figure 3 , Figure 5 and Figure 6 The opening / closing motor 40 is mounted on the second fixed housing 120. Specifically, the outer periphery of the second fixed housing 120 is provided with an annular protrusion 123. The opening / closing motor 40 is supported on the annular protrusion 123. The rotary motor 30 and the opening / closing motor 40 are distributed on both sides of the annular protrusion 123.

[0053] The manner in which the rotor 320 is connected to the rotating clamp 20 is not limited. In some embodiments, reference is made to... Figure 3 and Figure 4 A connecting cover 250 is provided on the bottom outer periphery of the rotating clamp 20. The connecting cover 250 is sleeved and fixed on the rotor 320. The connecting cover 250 and the rotating clamp 20 rotate together relative to the fixed base 10. An annular space 260 is formed between the connecting cover 250 and the bottom of the rotating clamp 20. The opening and closing motor 40 is located in the annular space 260.

[0054] For example, the connecting cover 250 includes a flange cover 251 and a connecting ring 252. The flange cover 251 surrounds the first clamping body 210 and the second clamping body 220 and is fixed to the first clamping body 210. The upper end of the connecting ring 252 is fixedly connected to the outer periphery of the flange cover 251, and the lower end is connected to the top of the fixed base 10 and sleeved and fixed on the rotor 320. An annular space 260 is formed between the connecting ring 252 and the bottom of the rotating clamping body 20. In other embodiments, the flange cover 251 and the connecting ring 252 can be separately formed. The connecting ring 252 can also be integrally formed with the rotor 320, that is, the connecting cover 250 can be integrally formed with the rotor 320.

[0055] In this embodiment, by providing a connecting cover 250 on the bottom outer periphery of the rotating clamp 20, it is convenient to connect with the rotor 320 of the rotating motor 30, so that the rotating motor 30 can directly drive the rotating clamp 20 to rotate through its rotor 320. The connecting cover 250 also serves to enclose and protect internal components (such as the opening and closing motor 40, the rotating motor 30, etc.).

[0056] In some embodiments, reference is made to Figure 3 and Figure 6 The first fixed shell 110 includes a ring body 111 and a stepped portion 112 extending inward from the inner wall of the ring body 111. The stepped portion 112 is fixedly connected to the second fixed shell 120, and the stator 310 is fixedly supported on the stepped portion 112.

[0057] refer to Figure 3 and Figure 6 The stepped portion 112 connects the inner wall of the ring 111 to the outer periphery of the second fixed shell 120, and forms the bottom wall of the first fixed shell 110. Optionally, the stepped portion 112 and the second fixed shell 120 are in a concave-convex fit, such that the stepped portion 112 is configured to include a multi-level stepped surface, and the second fixed shell 120 is correspondingly provided with a matching multi-level stepped surface.

[0058] The stepped portion 112 connects the first fixed housing 110 and the second fixed housing 120 on one hand, and also serves as a support element for the stator 310, limiting the axial position of the stator 310. Besides being fitted and fixed to the second fixed housing 120, the stator 310 can also be fixedly supported by the stepped portion 112, thereby providing stability to the stator 310. Furthermore, the stepped portion 112 extends axially towards the side opposite to the rotary motor 30, thus serving as a connector for mating with the main unit 200.

[0059] In some embodiments, reference is made to Figure 3 and Figure 5The air inlet 2111 is rotatably inserted into the second fixed housing 120; wherein the second fixed housing 120 is fixedly provided with the first grille 130, the air inlet 2111 is provided with the second grille 2112, and the second grille 2112 is rotatably connected to the first grille 130 through the connector 140.

[0060] The first grille section 130 and the second grille section 2112 are both components with multiple air passages. After the two are connected, the inner cavity of the second fixed shell 120 still maintains the state of connecting the air inlet end 2111 of the air duct 211 with the air outlet of the main unit 200.

[0061] refer to Figure 3 and Figure 5 The second fixed housing 120 is generally cylindrical. In the axial direction of the rotary motor 30, the second fixed housing 120 includes a large-diameter portion 121 and a small-diameter portion 122 connected to each other. Figure 3 In this configuration, the axial directions of the rotary motor 30 and the opening / closing motor 40 are vertical. The large-diameter portion 121 is adapted to the air inlet 211 of the air duct 211, allowing the air inlet end 2111 to be rotatably embedded within the large-diameter portion 121. A sealing ring is also provided between the outer peripheral wall of the air inlet end 2111 and the inner wall of the large-diameter portion 121. The sealing ring is fitted and fixed to the outer peripheral wall of the air inlet end 2111. A stepped surface is provided on the inner wall of the small-diameter portion 122. A first grille portion 130 is fixedly mounted on the stepped surface. A second grille portion 2112 is supported by the first grille portion 130.

[0062] For example, the second grille portion 2112 rests against the first grille portion 130; the connector 140 is fixedly connected to the first grille portion 130 and rotatably connected to the second grille portion 2112. Optionally, the connector 140 passes through the first grille portion 130 from below and extends into the second grille portion 2112; the connector 140 includes a threaded portion fixedly connected to the first grille portion 130 and an optical shaft portion rotatably connected to the second grille portion 2112. For example, the connector 140 is a bearing, and the first grille portion 130 and the second grille portion 2112 are at least partially nested, and a bearing is provided at the nested engagement.

[0063] In this application, by setting grilles on the second fixed shell 120 and the air inlet 2111 respectively, the relative rotation between the first clamp 210 and the second fixed shell 120 is achieved while ensuring the unobstructed air inlet channel.

[0064] refer to Figure 3 , Figure 5 and Figure 6The hair styling device also includes an eccentric mechanism 50. The output shaft 410 of the opening and closing motor 40 is connected to the second clamp 220 via the eccentric mechanism 50. Specifically, the eccentric mechanism 50 is fixed to the inner wall of the annular space 260, and the eccentric mechanism 50 is drive-connected to the output shaft 410 of the opening and closing motor 40. The eccentric mechanism 50 converts the rotational motion of the output shaft 410 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.

[0065] Further, refer to Figure 5 and Figure 7 The second fixed shell 120 has an annular protrusion 123 on its outer periphery; the eccentric mechanism 50 includes an eccentric wheel 510 and a support frame 520. The support frame 520 is fixed to the annular protrusion 123. The opening and closing motor 40 is installed on the support frame 520. The eccentric wheel 510 is installed on the output shaft 410 of the opening and closing motor 40. The eccentric wheel 510 is located on one side of the second clamp 220.

[0066] In the embodiments of this application, by providing the annular protrusion 123 and the support frame 520, the position of the eccentric wheel 510 in the axial direction of the opening and closing motor 40 is raised, so that the bottom ends of the eccentric wheel 510 and the second clamping body 220 correspond in height in the axial direction of the opening and closing motor 40, and the outer peripheral surface 511 of the eccentric wheel 510 can act on the second clamping body 220. As shown in the figure, in the axial direction of the opening and closing motor 40, the bottom ends of the eccentric wheel 510 and the second clamping body 220 are both located above the second fixed shell 120.

[0067] For example, the eccentric mechanism 50 includes an eccentric wheel 510, the rotation axis of which is parallel to the rotation axis of the first clamp 210, and the outer peripheral surface 511 of the eccentric wheel 510 abuts against the second clamp 220; the eccentric wheel 510 has a first position and a second position within its own rotation range, wherein in the first position, the eccentric wheel 510 causes the second clamp 220 to open relative to the first clamp 210, and in the second position, the second clamp 220 and the first clamp 210 are closed.

[0068] In this application, references Figure 3 , Figure 5 and Figure 5 The rotation axis of the eccentric wheel 510 is parallel to the rotation axis of the first clamp 210; the rotation plane of the eccentric wheel 510 is perpendicular to the rotation axis of the first clamp 210 and parallel to the rotation axis of the second clamp 220 when it rotates relative to the first clamp 210. Figure 3 In the figure, the rotation axis of the eccentric wheel 510 and the rotation axis of the first clamp 210 are parallel to the plane of the drawing, while the rotation axis of the second clamp 220 when rotating relative to the first clamp 210 is perpendicular to the plane of the drawing.

[0069] When the eccentric wheel 510 rotates, its outer peripheral surface 511 can act on the bottom end of the second clamp 220. Furthermore, when the eccentric wheel 510 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 511 of the eccentric wheel 510 is, for example, a cam surface. Relative to the center of the eccentric wheel 510, 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.

[0070] 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 rotary motor 30 and an opening / closing motor 40, and is used to control the operation of the rotary motor 30 and the opening / closing motor 40.

[0071] The hair styling device 1 of this application embodiment, through the control of the rotary motor 30 and the opening / closing motor 40 by the main unit 200, can automatically curl hair left and right and straighten hair. Specifically, the opening / closing motor 40 is energized to drive the first clamp 210 and the second clamp 220 of the rotating clamp 20 to open to insert hair, and then the electromagnet is de-energized to clamp the hair with the first clamp 210 and the second clamp 220. Afterwards, when the rotary motor 30 is not working, the user can straighten hair; when the rotary motor 30 is working, the rotating clamp 20 rotates, and the user can curl hair. By rotating the rotary motor 30 in opposite directions, left and right curling is automatically achieved.

[0072] Furthermore, the host 200 includes a first control button 201 for controlling the rotary motor 30 and a second control button 202 for controlling the opening and closing motor 40; in response to the first control button 201 being triggered, the rotary motor 30 drives the rotary clamp 20 to rotate, and in response to the second control button 202 being triggered, the opening and closing motor 40 controls the second clamp 220 to open relative to the first clamp 210.

[0073] 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 rotary motor 30 by repeatedly turning it on and off, or it can be configured to switch the forward and reverse directions of the rotary motor 30 by pressing it in different directions.

[0074] 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, and the main unit 200 controls the telescopic shaft of the opening and closing 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 perform a straightening or curling operation; or the main unit 200 can automatically control the rotation motor 30 to rotate according to a preset program to perform a curling operation.

[0075] 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.

[0076] A third aspect of this application provides a method for controlling a hair styling device 1. (See also...) Figure 9 The control method for hair styling device 1 includes the following steps.

[0077] S100: Control the output shaft 410 of the opening and closing motor 40 to rotate, so that the second clamp 220 opens relative to the first clamp 210.

[0078] S200, the output shaft 410 of the control opening and closing motor 40 is reset, so that the second clamp 220 and the first clamp 210 are closed to clamp the hair.

[0079] 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.

[0080] Furthermore, the control method for hair styling device 1 also includes the following steps:

[0081] S300: Control the rotor 320 of the rotary motor 30 to rotate, thereby driving the second clamp 220 and the first clamp 210 to rotate for curling.

[0082] S400, the rotor 320 of the rotary motor 30 is controlled to stop rotating.

[0083] S500: After the hair is removed from between the first clamp 210 and the second clamp 220, the rotor 320 of the rotary motor 30 is controlled to reset.

[0084] After the second clamp 220 and the first clamp 210 close and clamp the hair, the rotor 320 of the rotary motor 30 is rotated in a predetermined direction, which drives the second clamp 220 and the first clamp 210 to rotate and perform a curling operation. At this time, either left-hand curling or right-hand curling can be performed.

[0085] Furthermore, S200 includes:

[0086] S210. When hair is detected between the second clamp 220 and the first clamp 210, the output shaft 410 of the opening and closing motor 40 is reset.

[0087] Optionally, 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 disposed 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 410 of the opening and closing motor 40 to reset according to a preset program, so that the second clamp 220 and the first clamp 210 can clamp the hair.

[0088] Optionally, the rotation angle of the output shaft 410 of the opening and closing motor 40 can be detected by an angle sensor, thereby enabling precise control of the reset of the output shaft 410 of the opening and closing motor 40.

[0089] Furthermore, the S300 includes:

[0090] S310. When the hair styling device 1 is detected to be located on the left side of the head, the rotor 320 of the rotary motor 30 is controlled to rotate in a first direction.

[0091] S320. When the hair styling device 1 is detected to be located on the right side of the head, the rotor 320 of the rotary motor 30 is controlled to rotate in a second direction, wherein the second direction is opposite to the first direction.

[0092] For example, in S310 and S320, the gyroscope and image sensor can work together to identify whether the hair styling tool 1 is located on the left or right side of the head, and whether it has shifted between the left and right sides. In this way, different directions of curling operations can be performed in a timely manner according to the position of the hair styling tool 1.

[0093] Using the control method of the hair styling device 1 of this application, the user can choose to straighten hair or curl hair in both the left and right directions.
