[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0037] In the description of the embodiments of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0038] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0039] In existing curling irons with a pressing handle, the maximum number of revolutions of the curling assembly is generally determined by the pressing stroke of the pressing handle, and the pressing stroke of the pressing handle is generally fixed due to the internal space of the curling iron. The pressing handle can also be understood as a pressing assembly, which is mainly used to receive external force to perform a pressing operation. When the pressing stroke is fixed, the maximum number of revolutions of the curling assembly is also limited to a fixed value. However, the requirements for the maximum number of revolutions of the curling assembly in different application scenarios of the curling iron are also different, and existing curling irons are difficult to meet the usage requirements in various application scenarios. Therefore, an embodiment of the present application proposes a curling iron that can adjust the maximum number of revolutions of the curling assembly by adjusting the pressing stroke of the pressing assembly in the curling iron.

[0040] The following will be combined Figure 1 , Figure 2 and Figure 3 , the curling iron of the embodiment of the present application is described, specifically:

[0041] The curling iron provided in the embodiment of the present application mainly comprises: a curling assembly 1, a handheld part 2 and a power unit 3, wherein the power unit 3 mainly comprises a pressing assembly 31 and a transmission assembly 32; wherein the transmission assembly 32 is mainly a multi-stage power assembly, and adjacent power assemblies are coordinated. The pressing assembly 31 and the transmission assembly 32 are arranged on the handheld part 2, specifically, the transmission assembly 32 is arranged inside the handheld part 2, the pressing assembly 31 is mainly arranged on the outside of the handheld part 2, and the pressing assembly 31 can accept an externally applied force to perform a pressing operation. The pressing assembly 31 is in transmission connection with the transmission assembly 32, and the pressing assembly 31 can transmit the externally applied force to the transmission assembly 32.

[0042] The pressing component 31 is also provided with a first elastic component 311, and one end of the first elastic component 311 that contacts the pressing component 31 is connected to the pressing component 31, and when the pressing component 31 moves, it will also drive the first elastic component 311 to move. The first elastic component 311 can be a spring or other elastic element, which is not limited here. The housing 012 of the handheld part 2 is provided with a gear adjustment part 21, and the gear adjustment part 21 can be a push button, which is mainly used to adjust the maximum number of rotations of the curling component. The handheld part 2 is also provided with a stopper 22 connected to the gear adjustment part 21, and one end of the stopper 22 is provided with a plurality of step structures 221, and one end of the stopper 22 can be the head or tail of the stopper 22, which is not limited here. Moving the gear adjustment part 21 can move the stopper 22 and then adjust the position of the plurality of step structures 221, so that different step structures 221 correspond to the first elastic component 311, and the position is mainly the step position of the plurality of step structures 221.

[0043] When the pressing assembly 31 is subjected to external pressure, the pressing assembly 31 moves toward the inside of the hand-held part 2. Under the pressure of the pressing assembly 31, the first elastic component 311 moves toward the corresponding step structure 221 and abuts against the corresponding step structure 221 to be deformed. The deformed first elastic component 311 applies a force to the transmission assembly 32 through the pressing assembly 31, so that the transmission assembly 32 drives the curling assembly 1 to rotate. When the pressing assembly 31 releases the external pressure, the deformed first elastic component 311 abuts against the step structure 221, and pushes the pressing assembly 31 to reset under the action of the elastic force.

[0044] In a curling iron provided by an embodiment of the present application, a gear adjustment part is used to adjust the positions of multiple step structures so that different step structures correspond to the first elastic part; when the pressing component is subjected to pressure, the first elastic part abuts against the corresponding step structure under the pressure of the pressing component, and the deformed first elastic part applies a force to the transmission component so that the transmission component drives the curling component to rotate. The pressing stroke of the pressing component is adjusted by the gear adjustment part, and different gears correspond to different maximum rotation numbers of the curling component, thereby adjusting the maximum rotation number of the curling component.

[0045] Further, combined with Figure 1 , Figure 4 and Figure 5 In the embodiment of the present application, the transmission assembly 32 of the curling iron includes: a sector gear 3211, a linkage gear set and a transmission bar 3214. The rotation center end of the sector gear 3211 is rotationally connected to the pressing assembly 31, the serrated end of the sector gear 3211 is linkage-coordinated with the linkage gear set, and the linkage gear set is linkage-coordinated with the transmission bar 3214. A fixedly connected rotating gear 3215 is provided at one end of the curling assembly 1 close to the handheld portion 2, and the rotating gear 3215 of the curling assembly 1 is linkage-coordinated with the transmission bar 3214. The power of the pressing assembly 31 is transmitted to the rotating gear 3215 of the curling assembly 1 through the sector gear 3211, the linkage gear set and the transmission bar 3214, so that the curling assembly 1 rotates. It can be understood that the linkage gear set includes gears with multiple linkages, and the higher the linkage level, the higher the number of turns that the curling assembly 1 can rotate.

[0046] Further, combined with Figure 1 and Fig.12, the transmission bar 3214 is also provided with a protrusion 32141, and the protrusion 32141 forms a slot 5 with the end wall in the curling iron. It can be understood that the protrusion 32141 can form a slot 5 with the end wall of the handheld part 2 or the end wall of the curling assembly 1, and the specific details are not limited here. The slot 5 is provided with a second elastic component 312, and the second elastic component 312 is similar to the first elastic component 311 mentioned above, and the specific details are not repeated here. The second elastic component 312 abuts against the protrusion 32141, and the second elastic component 312 is compressed when the pressing assembly 31 receives pressure. When the pressing assembly 31 releases pressure, the transmission bar 3214 can be pushed by elastic force to reset the pressing assembly 31. At this time, if either the first elastic component 311 or the second elastic component 312 is not invalid, the movement of the multi-stage linkage gear and the reset of the pressing assembly 31 can be guaranteed.

[0047] Further, such as Figure 6 and Figure 7 As shown, the linkage gear set includes a first double gear 3212 and a second double gear 3213, and the first double gear 3212 and the second double gear 3213 are respectively composed of two gears of different sizes assembled from top to bottom. Specifically, the curling iron is limited by the volume and the stroke of the pressure component, and a 4-stage linkage can be designed. Among them, the fan gear 3211 is linked with the smaller gear in the first double gear 3212 to form a first-stage linkage component; the larger gear in the first double gear 3212 is linked with the smaller gear in the second double gear 3213 to form a second-stage linkage component; the larger gear in the second double gear 3213 is linked with the transmission bar 3214 to form a third-stage linkage component; the transmission bar 3214 is linked with the rotating gear 3215 of the curling iron to form a fourth-stage linkage component. Specifically, under the action of the pressing component, the sector gear 3211 rotates toward the inside of the hand-held part. At this time, the sawtooth end of the sector gear 3211 coincides with the sawtooth end of the smaller gear of the first double gear 3212, and the sector gear 3211 drives the first double gear 3212 to rotate under the action of force; similarly, the sawtooth end of the larger gear of the first double gear 3212 coincides with the sawtooth end of the smaller gear of the second double gear 3213, thereby driving the second double gear 3213 to rotate; similarly, the sawtooth end of the larger gear of the second double gear 3213 coincides with one sawtooth end of the transmission bar 3214, thereby driving the transmission bar 3214 to move; finally, the other sawtooth end of the transmission bar 3214 coincides with the sawtooth end of the rotating gear 3215, thereby driving the rotating gear 3215 to rotate, and driving the curling component to rotate. In one practicable manner, the number of teeth of the rotating gear 3215 is consistent with the number of teeth of the smaller gear of the first double gear 3212 , which can make the pressing operation of the pressing assembly 31 more convenient.

[0048] Further, combined with Figure 1 , Figure 8and Fig. 9 The pressing component 31 is provided with a chamber with a preset space inside. The preset space is generally not too large due to the volume of the curling iron. The sector gear 3211 and the first double gear 3212 are mainly located in the chamber, and in order to meet the chamber space conditions, the radius of the first double gear 3212 is smaller than the sector radius of the sector gear 3211 to avoid interference.

[0049] Furthermore, only one double gear may be used in the transmission assembly to form a three-stage linkage, as shown in FIG. Fig.10 and Fig.11 As shown. The linkage gear set is a third double gear, which can be understood as the second double gear 3213 mentioned above. The sector gear 3211 is linked with the smaller gear in the second double gear 3213 to form a first-stage linkage assembly; the larger gear in the second double gear 3213 is linked with the transmission bar 3214 to form a second-stage linkage assembly; the transmission bar 3214 is linked with the rotating gear of the curling iron to form a third-stage linkage assembly, thereby driving the curling assembly to rotate. It can be understood that the double gears described above can also be coaxial gears or other transmission elements, which are not specifically limited here.

[0050] Further, the transmission bar in the transmission assembly can be a rack, a belt or a toothed chain, which is not specifically limited here. The transmission bar is mainly used to drive the curling assembly to rotate. Preferably, the transmission bar is a rack, and the tooth surfaces at both ends of the rack are on opposite sides.

[0051] Further, such as Figure 1 As shown, a protrusion 313 is further provided on the inner side of the rear end of the pressing assembly 31 , one end of the first elastic component 311 is connected to the protrusion 313 , and the first elastic component 311 is installed between the protrusion 313 and the trapezoidal structure 221 and corresponds to the trapezoidal structure 221 .

[0052] Further, such as Figure 1 As shown, the curling assembly is provided with an extended rotating shaft 11, an E-shaped meson 12, a sleeve 13 and a pressing block 14, the rotating gear 3215 of the curling assembly is fixedly mounted on the extended rotating shaft 11, the E-shaped meson 12 tightly sleeves the sleeve 13 on the rotating end of the extended rotating shaft 11, and the pressing block 14 fixes the sleeve 13 on the curling iron. Specifically, the pressing block 14 fixes the sleeve 13 on the electrode assembly housing 013 of the curling iron, limits the axial movement of the rotating gear 3215 of the curling assembly, and makes the curling assembly more stable when rotating.

[0053] Further, such as Figure 1As shown, the extension end of the curling assembly connected to the handheld part is also provided with an electrode sheet 16; the electrode sheet 16 is electrically connected to the heating element of the curling assembly, and the heating element of the curling assembly is located in the housing 014 of the curling assembly, and is used to provide electrical energy to the heating element. The motor sheet 16 wraps the extension end of the curling assembly to ensure that the heating element of the curling assembly still has contacts to conduct electricity when rotating.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
