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

[0034] See Figures 1 to 9 This application relates to a hair styling tool accessory 100. The hair styling tool accessory 100 is used to mate with a main unit (not shown) to form a hair styling tool. The hair styling tool accessory 100 includes a fixed housing 10, a rotating clamp 20, a first motor 30, and a second motor 40.

[0035] The fixed housing 10 is connected to the rotating clamp 20 and is used to dock with the main unit to deliver the airflow from the main unit to the rotating clamp 20. The inner cavity of the fixed housing 10 is used to construct an air inlet channel for delivering airflow into the rotating clamp 20.

[0036] The rotating clamp 20 is assembled onto the fixed housing 10 and rotates relative to the fixed housing 10. The rotating clamp 20 includes a first clamp 210, a second clamp 220, a connecting body 230, and a clamping member 240. At least one of the first clamp 210 and the second clamp 220 is provided with an air duct 201, which communicates with the inner cavity of the fixed housing 10. The connecting body 230 connects the first clamp 210 and the second clamp 220, and the clamping member 240 is rotatably disposed between the first clamp 210 and the second clamp 220.

[0037] refer to Figures 1 to 3 The first clamp 210 and the second clamp 220 are both roughly semi-cylindrical, and their bottom ends are connected by a connector 230 (see...). Figure 7 The bottom ends of the first clamp 210, the second clamp 220, and the connector 230 are located in the inner cavity of the fixed shell 10.

[0038] In this embodiment, both the first clamp 210 and the second clamp 220 are provided with air ducts 201. The bottom of the air duct 201 has an air inlet 2011, which communicates with the inner cavity of the fixed housing 10. The air duct 201 also has an air outlet 2012. When the hair styling accessory 100 is in use, the fixed housing 10 is connected to the main unit. The airflow delivered by the main unit during operation flows through the fixed housing 10 into the air duct 201 and exits from the air outlet 2012, styling the hair.

[0039] For example, taking the first clamp 210 as an example, the surface of the first clamp 210 facing away from the second clamp 220 is an arc-shaped surface, and an air outlet 2012 is provided on the arc-shaped surface along the circumference. For example, an air outlet 2012 is also provided on the side of the first clamp 210 facing the second clamp 220. The air outlet 2012 on the side of the first clamp 210 facing the second clamp 220 is also embedded with a heating element (not marked), which heats the airflow into hot air. Optionally, the heating element is a ceramic part or a metal part.

[0040] The clamping member 240 is rotatably disposed between the first clamping body 210 and the second clamping body 220, so that the clamping member 240 can cooperate with the second clamping body 220 to clamp the hair. A hair-clamping space can be formed between the clamping member 240 and the second clamping body 220, and when the clamping member 240 moves toward the second clamping body 220, the clamping member 240 and the second clamping body 220 can clamp the hair.

[0041] The first motor 30 is located on the connecting body 230 and is connected to the clamping member 240 for transmission, thereby driving the clamping member 240 to move relative to the second clamping body 220. Specifically, the first motor 30 is a reversible motor, so that the output shaft of the first motor 30 can rotate counterclockwise or clockwise, that is, it can rotate in two opposite directions, thereby driving the clamping member 240 to move closer to or away from the second clamping body 220, clamping or releasing the hair.

[0042] The second motor 40 is disposed inside the fixed housing 10 and is used to drive the rotating clamp 20 to rotate relative to the fixed housing 10. For example, the second motor 40 drives the rotating clamp 20 to rotate relative to the fixed housing 10 through a transmission connection with the connecting body 230. Specifically, the second motor 40 is a forward and reverse reversible motor, so that the second motor 40 can drive the rotating clamp 20 to rotate in two opposite directions, thereby realizing left curling or right curling.

[0043] After the hair styling accessory 100 of this application is connected to the main unit, the first motor 30 and the second motor 40 operate under the control of the main unit. When hair styling is required, hair is placed between the clamping member 240 and the second clamping body 220, and the first motor 30 clamps the hair between the clamping member 240 and the second clamping body 220. Afterwards, when the second motor 40 is not operating, the user can straighten hair; when the second motor 40 is operating, it drives the rotating clamping body 20 to rotate, allowing the user to curl hair. By rotating the second motor 40 in opposite directions, left and right curling is automatically achieved. Therefore, the hair styling accessory 100 of this application can clamp hair, perform left and right curling operations, and also straighten hair during use.

[0044] In some embodiments, reference is made to Figure 4 The first clamp 210 is equipped with a signal generating device 211, and the second clamp 220 is equipped with a signal receiving device 221. The signal generating device 211 and the signal receiving device 221 work together to monitor whether there is hair between the first clamp 210 and the second clamp 220. Specifically, the signal generating device 211 can emit a signal that can be received by the signal receiving device 221. Either the signal receiving device 221 or the signal generating device 211 is configured to communicate with a host computer. For example, if the signal receiving device 221 is configured to communicate with a host computer, and there is hair between the first clamp 210 and the second clamp 220, the signal is blocked by the hair, and the signal receiving device 221 cannot receive the signal, resulting in a sudden change in the signal sent from the signal receiving device 221 to the host computer.

[0045] For example, signal generating device 211 is an infrared transmitter such as an infrared emitting tube or board, and signal receiving device 221 is an infrared receiver such as an infrared receiving tube or board. For example, signal generating device 211 is an ultrasonic transmitter, and signal receiving device 221 is an ultrasonic receiver.

[0046] With this configuration, in this application, the host can determine whether there is hair between the first clamp 210 and the second clamp 220 based on whether the received signal changes abruptly. When there is hair between the first clamp 210 and the second clamp 220, the host controls the first motor 30 to drive the clamping member 240 to move and clamp the hair.

[0047] In some embodiments, reference is made to Figure 4 The first clamp 210 has a first receiving cavity 212, and the signal generating device 211 is located in the first receiving cavity 212 and is enclosed by the first insulating plate 213; and / or, the second clamp 220 has a second receiving cavity 222, and the signal receiving device 221 is located in the first receiving cavity 212 and is enclosed by the second insulating plate 223.

[0048] refer to Figure 4In this application, the signal generating device 211 is disposed in the first receiving cavity 212 of the first clamp 210; the first insulating plate 213 can prevent damage to the signal generating device 211 when clamping hair. The signal receiving device 221 is disposed in the first receiving cavity 212 of the first clamp 210, and the second insulating plate 223 can prevent damage to the signal receiving device 221 when clamping hair.

[0049] Optionally, the first receiving cavity 212 is isolated from the air duct 201 in the first clamp 210 to prevent the high-temperature airflow from damaging the signal generating device 211 during hair curling. Optionally, the second receiving cavity 222 is isolated from the air duct 201 in the second clamp 220 to prevent the high-temperature airflow from damaging the signal receiving device 221 during hair curling.

[0050] In this application, the signal generating device 211 is specifically an infrared emitting plate. The signal generating device 211 is also specifically an infrared receiving plate. The infrared emitting plate is disposed on the first insulating plate 213, and the infrared receiving plate is disposed on the second insulating plate 223. Both the signal generating device 211 and the infrared receiving plate are configured as plate structures, which can provide a large emitting or receiving area, thereby improving sensing sensitivity.

[0051] In some embodiments, reference is made to Figures 3 to 5 The first clamp 210 has a receiving cavity 214, and the clamping member 240 is configured to be at least partially located within the receiving cavity 214.

[0052] For example, the clamping member 240 includes a connecting rod 241 and a clamping plate 242 connected to each other. The clamping plate 242 is configured to rotate relative to the first clamping body 210. The connecting rod 241 is drively connected to the output shaft of the first motor 30. The clamping plate 242 can enter the first clamping body 210 completely or partially. Figure 4 The diagram illustrates the situation when the clamp 242 is located inside the receiving cavity 214, and also uses a dotted line to indicate the situation when it extends out of the receiving cavity 214 and approaches the second clamp 220.

[0053] This design allows the clamping plate 242 to retract at least partially into the first clamping body 210 when not clamping hair, preventing damage to the clamping plate 242. Furthermore, by allowing the clamping member 240 to be partially located within the receiving cavity 214, the space occupied is reduced, resulting in a more compact structure.

[0054] In some embodiments, reference is made to Figures 3 to 5 The axis of the first motor 30 is parallel or coincident with the rotation axis R of the rotating clamp 20. The clamping member 240 includes a connecting rod 241 and a clamping plate 242. The connecting rod 241 is arranged radially along the first motor 30 and is connected to the output shaft of the first motor 30. The clamping plate 242 is arranged at an angle to the connecting rod 241 and rotates in the circumferential direction defined by the rotation axis R of the rotating clamp 20.

[0055] For example, the first motor 30 is located within the gap between the first clamping body 210 and the second clamping body 220. The axis of the first motor 30 coincides with the axis of rotation R of the rotating clamping body 20 when it rotates relative to the fixed housing 10. The connecting rod 241 is arranged radially along the first motor 30 and is drively connected to the output shaft of the first motor 30 through a transmission mechanism 310. The transmission mechanism 310 includes at least one pair of gears. The connecting rod 241 and the clamping plate 242 form an L-shaped structure. The clamping plate 242 is rotatably disposed on the rotating clamping body 20 near the outer peripheral edge of the rotating clamping body 20.

[0056] For example, one end of the connecting rod 241 includes two forked arms 2411, which are offset circumferentially in the direction defined by the rotation axis R of the rotating clamp 20 and are both connected to the clamping plate 242. This configuration provides two transmission connection points between the connecting rod 241 and the clamping plate 242, which can stably support the clamping plate 242 and make its rotation more stable.

[0057] By setting a connecting rod 241 extending radially along the first motor 30, the rotational motion of the output shaft of the first motor 30 can be converted into the circumferential rotation of the clamping plate 242. In this way, the setting of the connecting rod 241 utilizes the interval between the first clamping body 210 and the second clamping body 220, so that the clamping member 240 has little impact on the setting of the air duct 201 in general, so that the air duct 201 inside the two clamping bodies can be as large as possible without increasing the volume of the first clamping body 210 or the second clamping body 220.

[0058] In other embodiments, the clamping member 240 is configured to move linearly relative to the second clamping body 220. For example, the clamping member 240 includes a connecting rod 241 and a clamping plate 242. The transmission mechanism 310 is a rotary-linear motion conversion mechanism. The rotational motion of the output shaft of the first motor 30 is converted into the linear motion of the connecting rod 241 through the transmission mechanism 310. The rotary-linear motion conversion mechanism may be, for example, a gear and rack mechanism, wherein the gear is drivenly connected to the output shaft of the first motor 30, and the rack is fixedly connected to the connecting rod 241 or is integral with the connecting rod 241.

[0059] In some embodiments, reference is made to Figure 4 The second clamp 220 is provided with a flexible buffer 224, which is located on the extension line of the rotation trajectory of the clamping member 240; or the clamping member 240 is provided with a flexible buffer 224 on the side facing the second clamp 220.

[0060] refer to Figure 4In this application, a flexible buffer 224 is provided on the side of the clamping plate 242 of the second clamping body 220 facing the clamping member 240. The flexible buffer 224 is, for example, a rubber pad, but is not limited thereto. The flexible buffer 224 is located on the extension line of the rotation trajectory of the clamping member 240. In this way, when the clamping member 240 rotates toward the second clamping body 220 and clamps the hair, the flexible buffer 224 can also prevent the hair from being rigidly clamped, avoiding the risk that the hair cannot be removed in case of an accident.

[0061] For example, the flexible buffer 224 is a rubber pad. The rubber pad is fixed to the second clamp 220. The rubber pad is either bonded to the second clamp 220 or the surface of the second clamp 220 has a groove (not shown) in which the rubber pad is held and fixed.

[0062] In other embodiments, the flexible buffer 224 may also be disposed on the side of the clamping member 240 facing the second clamping body 220. In this way, the flexible buffer 224 moves with the clamping member 240 and can clamp the hair together with the second clamping body 220, avoiding the hair being rigidly clamped and avoiding the risk of the hair being unable to be removed in case of an accident.

[0063] In some embodiments, reference is made to Figures 7-9 The fixed shell 10 is provided with an air inlet cavity 101; the bottom outer periphery of the rotating clamp 20 is provided with a connecting cover 250, which is connected to the air duct 201 and is rotatably provided on the outer periphery of the air inlet cavity 101.

[0064] The top of the fixed housing 10 has an opening (not marked). The connecting cover 250 is located inside the fixed housing 10. The first clamp 210 and the second clamp 220 extend out of the fixed housing 10 from the opening. The connecting cover 250 is rotatably fitted onto the air inlet cavity 101, thereby connecting the air inlet cavity 101 with the air ducts 201 inside the two clamps. Optionally, the axis of the connecting cover 250 coincides with or is parallel to the axis of the air inlet cavity 101.

[0065] In this application, a connecting cover 250 is provided on the bottom outer periphery of the rotating clamp 20, and a straight air intake path is established between the connecting cover 250 and the air intake cavity 101, resulting in high air intake efficiency.

[0066] Optional, see reference Figures 7 to 9 The inner wall of the fixed shell 10 is also provided with an arc-shaped step portion 102. The connecting cover 250 is rotatably supported on the arc-shaped step portion 102. Multiple arc-shaped step portions 102 may be provided at intervals in the circumferential direction defined by the axis of the rotating clamp 20.

[0067] The arc-shaped step portion 102 acts as a limit in the axial direction of the fixed housing 10. In the axial direction of the first motor 30, the upward movement of the connecting cover 250 is limited by the top wall of the fixed housing 10, and the upward movement of the connecting cover 250 is limited by the arc-shaped step portion 102.

[0068] For example, the fixed shell 10 includes a first shell 110 and a second shell 120. The air inlet cavity 101 is disposed in the first shell 110, and the inner wall of the second shell 120 is provided with an arc-shaped step portion 102 that supports the connecting cover 250.

[0069] The first housing 110 and the second housing 120 are detachably connected in the axial direction of the first motor 30, thereby facilitating assembly with the rotating clamp 20 and the second motor 40. The first housing 110 has a connector on its side opposite to the second housing 120 for detachable connection with the main unit. The top wall of the second housing 120 has the aforementioned opening.

[0070] Optionally, an annular sealing portion (not shown) is provided between the inner wall of the fixed housing 10 and the connecting cover 250. The annular sealing portion is in sealing contact with the outer peripheral wall of the connecting cover 250 and with the inner wall of the fixed housing 10. The annular sealing portion is, for example, a sealing ring that is sleeved and fixed on the outer periphery of the connecting cover 250.

[0071] By setting an annular sealing part, the sealing between the connecting cover 250 and the fixed shell 10 is increased. The airflow delivered by the main unit can only flow through the air inlet cavity 101 to the connecting cover 250 and then to the air duct 201, thereby avoiding leakage of the airflow delivered by the main unit and improving the air outlet efficiency of the hair styling tool accessory.

[0072] In some embodiments, reference is made to Figure 2 and Figure 5 The rotating clamp 20 also includes a protective cover 260. The protective cover 260 is located between the first clamp 210 and the second clamp 220, and covers the first motor 30. The protective cover 260 is connected to at least one of the connecting cover 250 and the connecting body 230. The protective cover 260 isolates the first motor 30, the transmission mechanism 310, and the connecting rod 241 from the external space, providing protection while also maintaining a clean appearance.

[0073] refer to Figures 7 to 9 The second motor 40 is located between the inner wall of the fixed housing 10 and the outer wall of the air inlet cavity 101. The rotor 410 of the second motor 40 is sleeved on the outer wall of the air inlet cavity 101, and the connecting cover 250 is fixed to the rotor 410.

[0074] A placement space is formed between the outer wall of the air inlet cavity 101 and the inner wall of the fixed housing 10. The second motor 40 is located within this placement space. The axis of the second motor 40 coincides with the axis of the first motor 30. The rotor 410 of the second motor 40 is rotatably mounted on the air inlet cavity 101, and the rotor of the second motor 40 is also fixed to the connecting cover 250. The stator 420 of the second motor 40 is fixed inside the fixed housing 10. In this way, when the rotor 410 of the second motor 40 rotates, it can drive the rotating clamp 20 to rotate through the connecting cover 250.

[0075] In this application, a connecting cover 250 is provided on the bottom outer periphery of the rotating clamp 20, which facilitates the connection with the rotor 410 of the second motor 40, allowing the second motor 40 to directly drive the rotating clamp 20 to rotate via its rotor 410. Furthermore, the rotor 410 of the second motor 40 is integrated into the connecting cover 250 of the rotating clamp 20, resulting in a small radial footprint and a compact structure. Additionally, the connecting cover 250 is also fitted onto the outer wall of the air inlet cavity 101, enabling transmission between the connecting cover 250 and the rotor 410 while establishing a straight air inlet path between the connecting cover 250 and the air inlet cavity 101, resulting in high air inlet efficiency.

[0076] In some embodiments, reference is made to Figures 7 to 9 The connecting cover 250 includes a first ring portion 251 disposed on the bottom outer periphery of the rotating clamp 20 and a second ring portion 252 fixedly connected to the first ring portion 251. The second ring portion 252 is sleeved and fixed on the rotor 410.

[0077] For example, the first ring portion 251 is integrally formed with the rotating clamp 20. The second ring portion 252 is fixed to the bottom end of the first ring portion 251 by fasteners 253 such as bolts. The connecting cover 250 is sleeved on the outer periphery of the rotor 410 through the second ring portion 252, thereby being fixedly connected to the rotor 410. In other embodiments, the first ring portion 251 may also be fixed to the rotating clamp 20 by fasteners 253; the second ring portion 252 may also be integrally formed with the first ring portion 251.

[0078] For example, the second ring portion 252 includes a first inner ring surface 2521 and a second inner ring surface 2522 arranged in a stepped manner. The first inner ring surface 2521 is fitted onto the air inlet cavity 101 with a gap, and the second inner ring surface 2522 is fixed to the rotor 410. The inner diameter of the second inner ring surface 2522 is larger than the inner diameter of the first inner ring surface 2521.

[0079] In this application, by including a first ring portion 251 and a second ring portion 252 in the connecting cover 250, the first ring portion 251 is connected to the rotating clamp 20, and the second ring portion 252 is connected to the rotor 410, thereby achieving a transmission connection between the rotating clamp 20 and the second motor 40. Furthermore, in the two parts of the second ring portion 252, the first inner ring surface 2521 is clearance-fitted with the outer wall of the air inlet cavity 101, allowing the connecting cover 250 to be rotatably mounted on the outer wall of the air inlet cavity 101 and to communicate with the internal space of the air inlet cavity 101; the second inner ring surface 2522 is interference-fitted with the rotor 410, enabling a transmission connection between the connecting cover 250 and the rotor 410. This method eliminates the need for fasteners 253 to connect the connecting cover 250 and the rotor 410, while also achieving communication between the connecting cover 250 and the internal space of the air inlet cavity 101, simplifying the structural design.

[0080] In some embodiments, the rotor 410 of the second motor 40 is connected to a connecting cylinder 411 located within the air inlet cavity 101. The hair styling accessory 100 also includes a grid plate 50, a connector 60, and a fixing structure 70. The grid plate 50 is fixed to the inner wall of the fixing housing 10. The connector 60 passes through the connecting cylinder 411 and is rotatably connected to it. One end of the connector 60 is connected to the grid plate 50 along the axial direction of the connecting cylinder 411, and the second end is connected to the fixing structure 70. The fixing frame abuts axially against the connecting cylinder 411.

[0081] The grid plate 50 is specifically fixed to the inner wall of the air inlet cavity 101 and located at the entrance of the air inlet cavity 101. The entrance of the air inlet cavity 101 is used to communicate with the airflow outlet of the main unit. The grid plate 50 is a component with multiple air passages. The grid plate 50 can filter the airflow delivered by the main unit and prevent impurities such as hair from entering the air duct 201.

[0082] The rotor 410 is connected to the connecting cylinder 411, which is rotatably supported on the grid plate 50 via the connecting member 60. For example, a first bearing 412 and a second bearing 313 are fixedly installed axially inside the connecting cylinder 411, with the second bearing 313 close to the grid plate 50. The inner rings of the first bearing 412 and the second bearing 313 are fitted and fixed onto the connecting member 60. The fixing structure 70 abuts against the first bearing 412. By providing the first bearing 412 and the second bearing 313, the connecting member 60 can support the rotor 410 inside the air inlet cavity 101, enhancing the stability of the rotor 410 during rotation.

[0083] For example, the fixing structure 70 includes two fixing members 710 connected to the connector 60 and a gasket 720 disposed between the two fixing members 710. One fixing member 710 abuts against the first bearing 412, and the other fixing member 710 abuts against the gasket 720. In this way, the connection between the fixing structure 70 and the connector 60 is more reliable, preventing loosening.

[0084] Furthermore, an elastic element 414 is provided between the first bearing 412 and the second bearing 313. The two ends of the elastic element 414 abut against the first bearing 412 and the second bearing 313 respectively, axially limiting the first bearing 412 and the second bearing 313. In addition, the elastic force of the elastic element 414 allows the first bearing 412 to tightly abut against the fixing member 710, while not affecting the relative rotation between the connecting member 60 and the connecting cylinder 411.

[0085] A second aspect of this application also provides a hair styling device, including the aforementioned hair styling device accessory 100 and a main unit. The main unit is connected to the hair styling device accessory 100 and electrically connected to a first motor 30 and a second motor 40, for controlling the operation of the first motor 30 and the second motor 40.

[0086] The hair styling tool of this application embodiment controls a first motor and a second motor via a main unit, enabling it to clamp hair and automatically curl and straighten it. Specifically, the first and second motors operate under the control of the main unit. When hair styling is needed, hair is placed between the clamping member and the second clamping body, and the first motor clamps the hair between the clamping member and the second clamping body. Afterward, when the second motor is not operating, the user can straighten the hair; when the second motor is operating, it drives the rotating clamping body to rotate, allowing the user to curl the hair. By rotating the second motor in opposite directions, left and right curling is automatically achieved. Therefore, the hair styling tool accessory of this application can clamp hair, curl it left and right, and straighten it during use.

[0087] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0088] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
