[0083] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0084] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0085] See Figures 1 to 8 The present invention provides a manually controlled hair curler with forward and reverse rotation control, comprising: a main body housing 10, a heat vent 40, a manual rotation mechanism 60, and a hair curling lever 30. One end of the heat vent 40 is mounted on one end of the main body housing 10. The manual rotation mechanism 60 includes a control button 603, a reversing slider 602, and a transmission assembly 604. The control button 603 and the reversing slider 602 are respectively disposed on the main body housing 10. The transmission assembly 604 is disposed within the main body housing 10. The reversing slide 602 is connected to the transmission assembly 604, and the transmission teeth of the transmission assembly 604 and the control button 603 are engaged with each other. The curling lever 30 is mounted on the outside of the heat exchanger 40, and one end of the curling lever 30 is engaged with the transmission teeth of the transmission assembly 604 so as to rotate under the control of the control button 603. The reversing slide 602 is used to control the reversing direction of the transmission assembly 604, thereby reversing the rotation direction of the curling lever 30.

[0086] Specifically, if Figure 1As shown in FIG, the control button 603 can be positioned above the main housing 10, and the reversing slider 602 can be positioned on a side of the main housing 10. A button through-hole 1011 is defined in the main housing 10, and the control button 603 is rotatably mounted on the button through-hole 1011. During use, the control button 603 can be pressed with an external force, and the pressing force causes the control button 603 to rotate. Rotation of the control button 603 transmits power to the transmission assembly 604, thereby rotating the gears of the transmission assembly 604. The power is then transmitted to the curling lever 30 via the transmission assembly 604, thereby rotating the curling lever 30. Since the curling lever 30 is positioned outside the heat exchanger 40, the curling lever 30 can rotate. To curl hair, after placing hair into the curling connector, the heating button controls the heating element 40 to heat, and the control button 603 controls the rotation of the curling lever 30, thereby curling the hair onto the outer surface of the heating element 40. The heating element 40 heats and shapes the hair, achieving the curling function. To reverse the rotation direction of the curling lever 30, the reversing slider 602 is moved to control the transmission assembly 604, which then drives the curling lever 30 in the opposite direction. This allows the user to reverse the rotation direction of the curling lever 30 as needed. In the embodiment of the present invention, the curling lever 30 can be manually controlled to rotate by controlling the button 603 to achieve curling, and the reversing sliding block 602 can be used to achieve reversal of the curling lever 30. Firstly, compared with the method of using a rotating wheel to drive the curling lever 30 to rotate, the curling lever 30 is more convenient to use. Secondly, compared with the method of using an electric drive to rotate the curling lever 30, the motor and the motor drive control circuit can be omitted, thereby saving costs and lowering the product price to meet actual market needs. Thirdly, the user can reverse the rotation direction of the curling lever 30 according to actual needs, which is convenient for the user.

[0087] See Figure 2 and Figure 4 The control button 603 may include a button main shell 6031 and a transmission plate 6032. The button main shell 6031 is connected to the transmission plate 6032. The button main shell 6031 or the transmission plate 6032 is rotatably connected to the host housing 10. The transmission plate 6032 is provided with an external transmission tooth at the contact point with the transmission assembly 604. The external transmission tooth is used to drive the transmission assembly 604 to rotate under the action of the button main shell 6031. Figure 2 and Figure 4As shown, the control button 603 rotates around the shaft under the action of an external force. The control button 603 comprises a main housing 6031 and a transmission plate 6032, which are fixedly connected. For example, the main housing 6031 and the transmission plate 6032 can be integrally molded to form the control button 603. A portion of the main housing 6031 is positioned above the main housing 10. When the main housing 6031 is pressed by an external force, the transmission plate 6032 rotates synchronously with the main housing 6031. External transmission teeth are provided at the contact point between the transmission plate 6032 and the transmission assembly 604. These teeth drive the transmission assembly 604, which in turn transmits power to the curling lever 30 through the transmission assembly 604, driving the curling lever 30 to rotate.

[0088] See Figures 5 to 8 The transmission assembly 604 includes a forward and reverse conversion gear set, which is connected to the reversing slide block 602 and is used to reverse the pressing and rotating of the control button 603, so as to convert the pressing and rotating of the control button 603 into a rotation that can drive the curling lever 30 to rotate on the upper surface of the heat exchanger 40; the forward and reverse conversion gear set is also used to reverse the rotation direction of the curling lever 30 under the control of the reversing slide block 602. Figures 5 to 8 As shown in , the forward and reverse conversion gear set includes: a disc direction-changing rotating gear 6044 and a rotating gear rod 6045, wherein the disc direction-changing rotating gear 6044 is configured to rotate under the drive of the control button 603; a direction-changing transmission tooth is provided on the upper surface of the disc direction-changing rotating gear 6044, and the direction-changing transmission tooth on one side of the disc direction-changing rotating gear 6044 engages with the rotating gear rod 6045 to drive the curling lever 30 to rotate in a first rotation direction via the rotating gear rod 6045; the rotating gear rod 6045 is further configured to move under the control of the reversing sliding block 602, and enable the direction-changing transmission tooth on the other side of the disc direction-changing rotating gear 6044 to engage with the rotating gear rod 6045 to drive the curling lever 30 to rotate in a second rotation direction via the rotating gear rod 6045; wherein the second rotation direction is opposite to the first rotation direction.

[0089] Specifically, if Figure 7As shown in , under the action of the reversing sliding block 602, the rotating gear rod 6045 can be moved to a position where it engages with the reversing transmission teeth on one side of the disk reversing rotating gear 6044. In this way, when the disk reversing rotating gear 6044 is controlled to rotate by the control button 603, the transmission teeth above the disk reversing rotating gear 6044 can engage with the teeth on the rotating gear rod 6045, thereby driving the rotating gear rod 6045 to rotate in the first rotation direction, and driving the curling lever 30 to rotate in the first rotation direction. When reversing is required, the reversing sliding block 602 can be toggled to move the rotating gear rod 6045 to a position where it engages with the reversing transmission teeth on the other side of the disk reversing rotating gear 6044 (as shown in FIG. 1 ). Figure 8 ). Thus, when the control button 603 controls the rotation of the disk direction-changing gear 6044, the disk direction-changing gear 6044 drives the rotating gear rod 6045 to rotate in the second rotation direction. This achieves rotational reversal of the rotating gear rod 6045, and thereby the curling lever 30. For example, when the first rotational direction is clockwise, the second rotational direction is counterclockwise.

[0090] See Figure 5 and Figure 6 The forward and reverse direction conversion gear set further includes: a rotating connector 6046, which is a hollow structure. The end of the rotating gear rod 6045 close to the hair curling lever 30 is provided with a transmission head 60452. The rotating connector 6046 is telescopically arranged in the hollow structure of the rotating connector 6046 to drive the hair curling lever 30 to rotate. Figure 5 and Figure 6 As shown in FIG, the hollow structure of the rotating connector 6046 allows the end of the rotating gear rod 6045 near the curling lever 30 to be inserted into the rotating connector 6046. Furthermore, the transmission head 60452 at one end of the curling lever 30 may be non-cylindrical. The hollow structure of the rotating connector 6046 is compatible with the transmission head 60452. This allows the transmission head 60452 to drive the rotating connector 6046 to rotate synchronously after insertion. A rotating external gear 60461 is also provided on the outer side of the end of the rotating connector 6046 near the curling lever 30. This external gear 60461 drives the curling lever 30 to rotate synchronously. Furthermore, when the reversing slider 602 drives the rotating gear to move, the transmission head 60452 can move within the rotating connector 6046, facilitating adjustment of the position of the reversing slider 602.

[0091] See Figures 4 to 6 The manual rotating mechanism 60 further includes: a rotating mechanism housing 601, the transmission assembly 604 is installed in the rotating mechanism housing 601, and the other end of the rotating gear rod 6045 is further provided with a gear rod rotating shaft 60451, and the gear rod rotating shaft 60451 is rotatably arranged at the tail end of the rotating mechanism housing 601. Figures 4 to 6 As shown in FIG, the rotating mechanism housing 601 may include a left rotating mechanism housing 6011 and a right rotating mechanism housing 6012. The left rotating mechanism housing 6011 and the right rotating mechanism housing 6012 may be fixedly connected by screws to mount the transmission assembly 604 within the rotating mechanism housing 601. By rotatably positioning the gear rod rotating shaft 60451 at the rear end of the rotating mechanism housing 601, the rotating gear rod 6045 may rotate around the gear rod rotating shaft 60451.

[0092] See Figure 2 and Figure 4 The manual rotation mechanism 60 further includes: a button reset spring 6035, the control button 603 is further provided with a shaft through-hole 6034, the control button 603 is rotatably connected to the rotation mechanism housing 601 through the shaft through-hole 6034; the control button 603 is further provided with a button reset shaft 6033, one end of the button reset spring 6035 is fixedly connected to the rotation mechanism housing 601, and the other end of the button reset spring 6035 is connected to the button reset shaft 6033, and the button reset spring 6035 is used to provide a reset force for the control button 603. Figure 2 and Figure 4 As shown in FIG, the control button 603 is rotatably connected to the rotating shaft within the rotating mechanism housing 601 via a rotating shaft through-hole 6034. When an external force is applied to the control button 603, the button return spring 6035 is required to reset the control button 603. Specifically, when the external force is applied to the control button 603, the control button 603 rotates, causing the button return shaft 6033 to move from one end of the button return through-hole 60122 in the right rotating mechanism housing 6012, adjacent to the button return spring 6035, to the other end, thereby stretching the button return spring 6035. When the external force is removed, the force of the button return spring 6035 pulls the button return shaft 6033 back, thereby resetting the control button 603. One end of the button return spring 6035 can be fixed to the outside of the rotating mechanism housing 601.

[0093] See Figures 4 to 6The transmission assembly 604 also includes an acceleration gear set, and the control button 603 is connected to the forward and reverse conversion gear set through the acceleration gear set to control the rotation acceleration of the forward and reverse conversion gear set; wherein, the acceleration gear set includes: a first rotating gear 6041, a second rotating gear 6042 and a speed-changing rotating gear 6043, the first rotating gear 6041 and the control button 603 are meshed with each other to rotate under the control of the control button 603; the second rotating gear 6042 and the first rotating gear 6041 are meshed with each other. The shaft is set, and the first rotating gear 6041 is used to drive the second rotating gear 6042 to rotate synchronously in one direction; the teeth of the speed-changing rotating gear 6043 and the second rotating gear 6042 are meshed with each other, and the number of teeth of the second rotating gear 6042 is greater than the number of teeth of the speed-changing rotating gear 6043. The speed-changing rotating gear 6043 is accelerated by the second rotating gear 6042; the speed-changing rotating gear 6043 is connected to the disc changing rotating gear 6044 to drive the disc changing rotating gear 6044 to rotate synchronously.

[0094] Specifically, if Figures 4 to 6As shown in FIG, pressing the control button 603 with an external force causes the control button 603 to rotate. The engagement between the control button 603 and the first rotating gear 6041 drives the first rotating gear 6041 to rotate synchronously. Because the first rotating gear 6041 is coaxially connected to the second rotating gear 6042 via helical teeth, when the first rotating gear 6041 rotates synchronously with the control button 603, the helical teeth simultaneously drive the second rotating gear 6042 to rotate in one direction. In other words, when the control button 603 rises and resets, it can drive the first rotating gear 6041 to rotate. However, because the helical teeth are interposed between the first and second rotating gears 6041 and 6042, when the first rotating gear 6041 rotates in the opposite direction, the first and second rotating gears 6041 and 6042 slip against each other, preventing the second rotating gear 6042 from rotating in the opposite direction. This ensures the one-way, synchronous rotation of the second rotating gear 6042 and the first rotating gear 6041. The rotation of the second rotating gear 6042 drives the speed-changing rotating gear 6043 to rotate. Because the second rotating gear 6042 has a greater number of teeth than the speed-changing rotating gear 6043, each rotation of the second rotating gear 6042 drives the speed-changing rotating gear 6043 to rotate multiple times, thereby achieving speed change. Furthermore, because the speed-changing rotating gear 6043 is coaxially arranged with the disk direction-changing rotating gear 6044, the speed-changing rotating gear 6043 drives the disk direction-changing rotating gear 6044 to rotate synchronously. This, in turn, drives the rotating gear rod 6045 to rotate, thereby driving the curling lever 30 to rotate. And because the rotating gear rod 6045 can move under the control of the reversing sliding block 602, the teeth of the rotating gear rod 6045 can engage with the teeth on one side or the other side of the disc reversing rotating gear 6044 to achieve clockwise or counterclockwise reversing rotation.

[0095] See Figure 7 and Figure 8 The reversing sliding block 602 is provided with a Y-shaped reversing head 6023, and the Y-shaped reversing head 6023 is connected to both ends of the rotating gear rod 6045, and the Y-shaped reversing head 6023 is used to drive the rotating gear rod 6045 to move and reverse; Figure 7 and Figure 8 As shown in FIG, the two Y-shaped hooks of the Y-shaped reversing head 6023 are respectively disposed at the ends of the rotating gear rod 6045. Thus, when an external force moves the reversing slide block 602 left and right, the rotating gear rod 6045 can also be driven to move left and right. This structure also makes the installation of the reversing slide block 602 more convenient.

[0096] See Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The bottom of the reversing sliding block 602 is respectively provided with a first reversing positioning hole 6021 and a second reversing positioning hole 6022. The main housing includes an upper housing 101 and a lower housing 102. The lower housing 102 is further provided with a spring positioning column 1021 at a position opposite to the first reversing positioning hole 6021 or the second reversing positioning hole 6022. The spring positioning column 1021 is used to position and fix the reversing movement of the reversing sliding block 602. Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown in , the reversing slide 602 is provided with two reversing positioning holes near the lower housing 102, and a spring positioning post 1021 is provided at a corresponding position on the lower housing 102.
