DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The core of the present invention is to provide a hair styling device, in which eccentric rotating shafts are arranged at both ends of the heating element in the longitudinal direction, so that the volume of the hair styling device is reduced and it is convenient to use and carry.

[0037] Please refer to Figures 1-7 , Figure 1 This is a schematic structural diagram of a specific embodiment of the hair styling device provided by the present invention; Figure 2 This is an exploded schematic diagram of the hair styling device provided by the present invention; Figure 3 This is a schematic diagram of the structure when the heating element rotates to the position closest to the lower shell; Figure 4 for Figure 3 A partial enlarged view of part A; Figure 5 This is a schematic diagram of the structure when the heating element rotates to the position farthest from the lower shell; Figure 6 for Figure 5 A partial enlarged view of part B; Figure 7 Schematic diagram of the explosion of the heating element.

[0038] The hair styler provided in this embodiment includes a lower housing, an upper housing pivotally connected to the lower housing, an elastic element 6 disposed between the lower and upper housings to enable the two to be relatively open, and a heating element 3. The lower housing is provided with a shaping portion for cooperating with the heating element 3 to shape hair.

[0039] The heating element 3 is rotatably mounted on the upper housing, and has at least two moldings disposed on its outer periphery;

[0040] The rotation axis of the heating element 3 is not colinear with the central axis thereof. The heating element 3 is rotated so that its different shaping parts cooperate with the shaping parts to form wave curls of different sizes.

[0041] It should be noted that the shaping part can be provided on the lower heating body assembly 5 of the lower shell, or can be a structure without heating function, which is determined according to the actual situation.

[0042] The number of the shaping part in the heating body 3 can be two relatively arranged or a plurality of circumferentially uniformly arranged, which is determined according to the actual situation.

[0043] When the hair shaper provided by the embodiment is used, the heating body 3 can be eccentrically rotated by rotating the heating body 3, and different shaping parts in the heating body 3 cooperate with the shaping part to form different shaping effects when the heating body 3 is rotated to different positions. The arrangement of the rotating heating body 3 does not affect the width of the heating body 3, and the space at both ends of the length direction of the heating body 3 is sufficient, so that the length of the hair shaper is not additionally increased, which is beneficial to realize the miniaturization of the hair shaper, facilitate the carrying and use of the hair shaper.

[0044] On the basis of the above embodiment, in order to enable the heating body 3 to be eccentrically rotated, an eccentric shaft can be arranged on the heating body 3, and the eccentric shaft is arranged on the upper shell.

[0045] It should be noted that the upper shell includes the upper handle 1 as a gripping part and the upper body 4 connected with the upper handle 1, and the lower shell includes the lower handle 2 and the shaping part connected with the lower handle 2.

[0046] The eccentric shaft can be an integral structure and is arranged in the length direction of the heating body 3 and extends out of both ends of the length direction of the heating body 3. Alternatively, a front eccentric shaft 351 and a rear eccentric shaft 311 coaxial with each other can be arranged at both ends of the length direction of the heating body 3.

[0047] As shown in Figure 3 , Figure 5 The arrangement of the front eccentric shaft 351 and the rear eccentric shaft 311 enables the size of the heating surface for shaping hair to be different when the heating body 3 is rotated to different working positions, so that different shaping effects can be formed. As shown in Figure 3 The heating body 3 is rotated to a position close to the lower heating body assembly 5, the depth of the shaping part in the heating body 3 for cooperating with the lower heating body assembly 5 is increased, and a large-sized wave roll can be formed. As shown in Figure 5 The heating body 3 is rotated to a position far away from the lower heating body assembly 5, the depth of the shaping part in the heating body 3 for cooperating with the lower heating body assembly 5 is reduced, and a small-sized wave roll can be formed. Of course, the heating body 3 can be arranged as a columnar structure with different sizes of heating protrusions on the surface, and different sizes of heating protrusions will cooperate with the lower heating body assembly 5 when the heating body 3 is rotated to different positions, so that more types of shaping can be formed.

[0048] When the hair styler is used, the heating body 3 can be switched to the styling part in the working position in size to adapt to different styling effects, and the heating body 3 is realized eccentric rotation through the front eccentric shaft 351 and the rear eccentric shaft 311 arranged at the two ends in the length direction, and the width of the heating body 3 is not increased, at the same time, since the space at the two ends in the length direction of the heating body 3 is sufficient, the length of the hair styler is not additionally increased, which is beneficial to realize the miniaturization of the hair styler, and the hair styler is convenient to carry and use.

[0049] It should be noted that the styling part is a heating surface of the heating body 3 for contacting the hair.

[0050] On the basis of the above embodiment, in order to facilitate the rotation control of the heating body 3, the first gear 3512 coaxial with the front eccentric shaft 351 is arranged in the heating body 3, the upper body 4 is provided with the second gear 41 engaged and driven with the first gear 3512, and the rotation push button 8 coaxial with the second gear 41 and capable of driving the second gear 41 to rotate is arranged; the rotation push button 8 is connected with the second gear 41.

[0051] In the use process, the rotation push button 8 can be rotated to drive the second gear 41 to rotate, the second gear 41 drives the first gear 3512 to rotate, and the front eccentric shaft 351 is driven to rotate, so that the heating body 3 rotates relative to the support 12.

[0052] Since the space on the side of the heating body 3 close to the power cord in the length direction is relatively large, the front eccentric shaft 351 can be installed on the side close to the upper handle 1 to make full use of the space.

[0053] In order to facilitate operation, as shown in Figure 1 In the use process, the rotation push button 8 can be rotated to drive the second gear 41 to rotate, the second gear 41 drives the first gear 3512 to rotate, and the front eccentric shaft 351 is driven to rotate, so that the heating body 3 rotates relative to the support 12.

[0054] Preferably, in order to avoid slipping in the operation process, anti-slip lines can be arranged on the surface of the rotation push button 8.

[0055] Preferably, the number of teeth of the second gear 41 is greater than that of the first gear 3512, so that the rotation push button 8 can rotate a smaller angle to make the heating body 3 rotate a larger angle.

[0056] In order to make the rotation push button 8 smoothly drive the second gear 41 to rotate, the rotation push button 8 can be connected with the second gear 41 through the connecting shaft 81, and the rotation push button 8 is fixed in the circumferential direction relative to the second gear 41.

[0057] Need to be explained, because the front eccentric shaft 351 is provided with the first gear 3512, therefore, the diameter of the front eccentric shaft 351 is greater than the diameter of the rear eccentric shaft 311.

[0058] On the basis of the above embodiment, the bracket 12 can be provided with a mounting hole for mounting the front eccentric shaft 351 and the rear eccentric shaft 311, and the outer peripheral portion of at least one of the front eccentric shaft 351 and the rear eccentric shaft 311 is provided with a limiting portion to rotate the heating body 3 within a range of not more than 180°.

[0059] The limiting portion can be a limiting protrusion 3511 protruding from the outer peripheral portion of the front eccentric shaft 351, and the mounting hole is provided with a limiting groove cooperating with the limiting protrusion 3511 to rotate the heating body 3 within a range of not more than 180°.

[0060] As shown in Figure 3 , Figure 5 In this specific embodiment, two limiting grooves can be arranged symmetrically at 180° in the circumferential direction of the mounting hole, and the outer peripheral portion of the front eccentric shaft 351 is provided with a limiting protrusion 3511 cooperating with the limiting grooves; when the limiting protrusion 3511 cooperates with the two limiting grooves, the heating body 3 is in the working position; in addition, the mounting hole in the bracket 12 provided on the upper shell for cooperating with the front eccentric shaft 351 can also be arranged as an arc structure less than 180°, and the limiting protrusion 3511 is limited when it rotates to the upper surface of the mounting hole in the bracket 12.

[0061] Need to be explained, the upper handle cover plate 11 is provided with a pressing portion for cooperating with the mounting hole on the bracket 12, and the pressing portion is provided with a pressing portion for cooperating with the outer peripheral portion of the front eccentric shaft 351 and an arc-shaped groove for rotating the limiting protrusion 3511.

[0062] As shown in Figure 4 , rotate the rotating push button 8, the heating body 3 rotates to the working position, the limiting protrusion 3511 cooperates with the limiting groove on one side of the mounting hole, and the size of the modeling part cooperating with the lower heating body 3 increases in depth at this working position, which can form a large roll, as shown in Figure 6 , the heating body 3 rotates to another working position, the limiting protrusion 3511 cooperates with the limiting groove on the other side of the mounting hole, and the size of the modeling part cooperating with the lower heating body 3 decreases in depth at this working position, which can form a small roll.

[0063] On the basis of the above embodiment, a tension spring 9 for avoiding the rotation of the heating body 3 relative to the support 12 in the working state can be further included. When the limiting protrusion 3511 cooperates with the limiting recess, the tension spring 9 provides a pre-tightening force for the heating body 3. One end of the tension spring 9 is connected with the heating body 3, and the other end is connected with the upper shell.

[0064] In use, when the limiting recess cooperates with the limiting protrusion 3511, the tension spring 9 is in a stretched state. If the heating body 3 rotates, the tension of the tension spring 9 needs to be overcome. Therefore, the heating body 3 can be kept relative to the support 12 in a specified state in the working state, so that the modeling effect is stable.

[0065] On the basis of the above embodiment, a first boss 91 for mounting the tension spring 9 can be arranged on the front eccentric shaft 351. The central axis of the first boss 91 is arranged non-collinearly with the central axis of the front eccentric shaft 351. The upper body 4 is provided with a second boss 92 for mounting the other end of the tension spring 9.

[0066] When the limiting protrusion 3511 cooperates with the limiting recess, the deformation amount of the tension spring 9 is the smallest. When the front eccentric shaft 351 rotates relative to the support 12 to the intermediate position, the deformation amount of the tension spring 9 is the largest.

[0067] Preferably, the first boss 91 and the second boss 92 are both cylindrical bosses.

[0068] In the process of rotating the heating body 3 relative to the support 12, when the limiting recess cooperates with the limiting protrusion 3511, the deformation amount of the tension spring 9 is the smallest. At this time, the heating body 3 is rotated relative to the support 12, and the elastic force of the tension spring 9 needs to be overcome. When the heating body 3 rotates relative to the support 12 to the intermediate position, the intermediate position refers to the case that the heating body 3 rotates to the 90° position when the rotation angle of the heating body 3 is 180°. After that, the heating body 3 is rotated again, the deformation of the tension spring 9 gradually decreases, the elastic force of the tension spring 9 provides power for the rotation of the heating body 3, and can assist the heating body 3 to rotate to another working position, so that the limiting protrusion 3511 cooperates with the limiting recess on the other side.

[0069] On the basis of the above embodiment, the heating body 3 can include a heating shell 32, a heating element 33 arranged inside the heating shell 32, a front cover 35 provided with a front eccentric shaft 351, a rear cover 31 provided with a rear eccentric shaft 311, and a pressing plate 34. The front cover 35 and the rear cover 31 are both detachably connected with the heating shell 32.

[0070] The heating body 3 is arranged in the form of an assembly, which can facilitate processing.

[0071] As Figure 2As shown, the power cord connected with the handle is provided with a power cord protective sleeve 7, the tail of the hair styler is provided with a tail cover 71, the lower handle 2 is provided with an upper handle cover plate 11 between the upper handle 1 and the upper body 4, the bracket 12 is detachably connected with the upper body 4, the second gear 41 is provided on the upper body 4 through a connecting piece, the mounting hole for cooperating with the rear eccentric shaft 311 at one end of the bracket 12 is a circular through hole, and the mounting hole for cooperating with the front eccentric shaft 351 at the other end of the bracket 12 is a semicircular through hole. The upper body 4 is provided with a long strip-shaped through hole, the rotating push button 8 can move along the length direction of the long strip-shaped through hole, and in the use process, the rotating push button 8 can drive the heating body 3 to rotate, when the rotating push button 8 is rotated to one end of the long strip-shaped through hole, the limiting protrusion 3511 cooperates with the limiting recess on the outside of the mounting hole, the outside here refers to the position shown in the cooperation position in the figure, the heating body 3 is located at a position close to the lower heating body assembly 5, at this time, the upper handle 1 and the lower handle 2 are relatively tightly closed, and the hair can form a larger size of curl degree; when it is needed to change the size of the curl degree, the rotating push button 8 can be rotated, the heating body 3 is rotated relative to the bracket 12, the limiting protrusion 3511 is rotated to cooperate with the limiting recess on the inside of the mounting hole, in the rotating process, at the beginning, the elastic force of the tension spring 9 needs to be overcome, after passing the intermediate position, under the elastic force of the tension spring 9, the heating body 3 is automatically rotated to the position where the limiting protrusion 3511 is rotated to cooperate with the limiting recess on the inside of the mounting hole, the inside here refers to the position shown in the cooperation position in the figure, the heating body 3 is located at a position far away from the lower heating body assembly 5, at this time, the upper handle 1 and the lower handle 2 are relatively tightly closed, and the hair can form a smaller size of curl degree.
