DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] refer to Figure 1 As shown, one embodiment of the present invention is an electric adjustable curling iron, comprising a handle 1, the front end of which is detachably connected to a cover 2, so as to facilitate disassembly and replacement of handles of different sizes and shapes; more importantly, the curling iron is also equipped with a drive motor 3, combined with Figure 2 As shown, the aforementioned driving motor 3 is installed inside the handle 1, and the output shaft of the driving motor 3 is dynamically connected to a plurality of connecting ribs 4 through an adjusting device. In order to facilitate the disassembly of the handle 1 and the end cover 2, the aforementioned adjusting device can be designed inside the annular structure of the cover 2. At the same time, the aforementioned adjusting device can be detachably connected to the output shaft of the driving motor 3, which is also convenient for disassembly; at the same time, the aforementioned connecting ribs 4 also need to be dynamically connected to their respective movable hair-planting combs 5, and a plurality of movable hair-planting combs 5 are distributed in an annular shape to form a cylindrical shape; the driving motor 3 is used to rotate forward and reverse, and the plurality of connecting ribs 4 are driven by the adjusting device, so that the plurality of movable hair-planting combs 5 are synchronously approached or away from the central axis of the cylindrical structure within a predetermined range, that is, the radial size of the circular comb of the curling iron can be infinitely adjusted.

[0025] As mentioned above, by detachably mounting the handle 1 on the end cover 2 and detachably connecting the drive motor 3 inside the handle 1 to the adjustment device, the handle 1 of different sizes can be conveniently replaced, and the drive motor 3 can also adjust the radial size of the curling iron through the adjustment device, and the radial size of any value can be formed within a predetermined range, which can adapt to various different curling styles. The radial size adjustment of the curling iron is performed by the drive motor, which is more convenient to use.

[0026] In the present invention, the inventor provides three different forms for the structure of the above-mentioned adjustment device, the purpose of which is to enable the motor to conveniently drive multiple movable hair planting combs 5 to move radially within a predetermined range. Therefore, under the above-mentioned idea of ​​the present invention, other structures other than these three forms are not excluded. In this embodiment, the inventor uses a guide plate 21 as the above-mentioned adjustment device, specifically connecting the guide plate 21 to the output shaft power of the drive motor 3, and combining Figure 3 As shown, the guide disc 21 needs to be designed with multiple arc-shaped guide grooves 22. The multiple arc-shaped guide grooves 22 are distributed in a divergent manner on the guide disc 21, and the ends of the multiple connecting ribs 4 are respectively inserted into their respective arc-shaped guide grooves 22. That is, when the driving motor 3 drives the guide disc 21 to rotate, the connecting ribs 4 are forced to move along a predetermined trajectory under the guidance of the arc-shaped guide grooves 22, so that the connecting ribs 4 move outward, driving the movable hair-planting comb 5 to move outward, and adjusting the radial size of the curling iron's circular comb. Conversely, when the driving motor 3 reverses, the connecting ribs 4 are still forced to move inward through the arc-shaped guide grooves 22 of the guide disc 21, driving the movable hair-planting comb 5 to move inward, and adjusting the radial size of the curling iron's circular comb. At the same time, in order to improve the stability of the multiple connecting ribs 4 moving inward / outward under the action of the arc-shaped guide grooves 22, a limiting groove 23 corresponding to the position of the multiple connecting ribs 4 can also be added to the above-mentioned cover 2, and the multiple connecting ribs 4 are respectively passed through their respective limiting grooves 23.

[0027] refer to Figure 4As shown, another embodiment of the present invention provides an adjustment device of another structure, which includes a first screw 31, a screw slider 32 and a plurality of connecting rods 33, wherein the first screw 31 is connected to the output shaft power of the above-mentioned drive motor 3, and then the aforementioned screw slider 32 is mounted on the first screw 31, the screw slider 32 is movably connected to the plurality of connecting rods 33, and the plurality of connecting rods 33 are movably connected to their respective connecting ribs 4; that is, the first screw 13 is driven by the drive motor 3 to rotate forward and reverse, so that the screw slider 32 moves back and forth on the first screw 31, and the connecting rib 4 is driven to move outward or inward through the connecting rod 33, thereby driving the movable hair planting comb 5 to move inward / outward to adjust the radial size of the circular comb of the curling iron. Similarly, in order to improve the stability of the multiple connecting ribs 4 moving inward / outward under the action of the connecting rod 33, a guide column 34 can be added to the cover 2, and the ends of the aforementioned multiple connecting ribs 4 are movably mounted on the guide column 34.

[0028] refer to Figure 5 and Figure 6 As shown, another embodiment of the present invention provides a new adjustment device structure, which is used in the same way as the adjustment device of the above structure. The adjustment device includes a first bevel gear 41 and multiple second screws 42. The aforementioned first bevel gear 41 is connected to the output shaft power of the drive motor 3, and a second bevel gear 43 is provided at the end of the second screw 42, and the second bevel gear 43 is meshed with the first bevel gear 41. Then, the ends of multiple connecting ribs 4 are respectively mounted on their respective second screws 42, and the two are threadedly matched. The drive motor 3 drives the first bevel gear 41 to rotate, and the first bevel gear 41 drives the multiple second gears 43 to rotate, and then, under the action of the thread, drives the connecting ribs 4 to reciprocate on their respective second screws 42, and then drives the movable hair planting comb 5 to move inward / outward to adjust the radial size of the curling iron circular comb. In this embodiment, preferably, in order to ensure the stability of the inward / outward movement of the plurality of connecting ribs 4 under the action of the second screw 42, a third bevel gear 44 can be further provided on the basis of the above structure. Figure 6As shown, the third bevel gear 44 is mirror-symmetrical to the first bevel gear 41, and the third bevel gear 44 is also connected to the power of the drive motor 3; at the same time, the second screw 42 is divided into two groups, and then the second bevel gear 43 at the end of the second screw 42 of the first group is meshed with the first bevel gear 41, and then the second bevel gear 43 at the end of the second screw 42 of the second group is meshed with the third bevel gear 44, and the ends of the multiple connecting ribs 4 are respectively mounted on the two second screws 42, that is, one connecting rib 4 is simultaneously mounted on one second screw 42 of the first group of second screws 42 and one second screw 42 of the second group of second screws 42; thereby, the first bevel gear 41 and the third bevel gear 44 are driven to rotate by the drive motor 3 at the same time, and the two drive their respective second bevel gears 43 to rotate at the same time, so that the upper and lower second screws 42 simultaneously drive their respective connecting ribs 4 to move inward / outward.

[0029] Based on the same purpose as above, in order to improve the stability of the inward / outward movement of the multiple connecting ribs 4 under the action of the second screws 42, screw grooves 45 corresponding to the second screws 42 can be added to the upper and lower parts of the end cover, and screw holes 46 corresponding to the second screws 42 can be provided on the side of the end cover. This allows the second screws 42 to be located in their respective screw grooves 45 and pass through the corresponding screw holes 6, thereby further improving the stability of the inward / outward movement of the connecting ribs 4.

[0030] In another embodiment of the present invention, in order to facilitate the installation of the movable hair planting comb 5 and the force transmission of the connecting rib 4, the movable hair planting comb 5 can be connected to the connecting rib 4 through the comb mounting seat 6, such as Figure 3 As shown, two movable hair-planting combs 5 can be installed on a comb mounting base 6. With this structure, if twelve movable hair-planting combs 5 are installed on the curling iron, only six connecting ribs 4 are required, further simplifying the structure of the curling iron. Moreover, the comb mounting base 6 can be designed to make the two installed movable hair-planting combs 5 at an angle to each other through the corresponding structural design. Based on the same idea as mentioned above, the movable hair-planting combs 5 can also be designed in the same way to be two to twenty. On the other hand, in order to enable the curling iron to generate heat and achieve the effect of an electric heating rod, a heating device 7 can be embedded in the comb mounting base 6, and the heating device 7 and the drive motor 3 are connected to a power supply. The power supply is also connected to the switch body. By heating the heating device 7 through the power supply, the heating of the movable hair-planting combs 5 of the entire curling iron can be achieved. At the same time, by utilizing the detachable mounting structure between the comb mounting base 6 and the movable hair-planting combs 5, the curling iron can be used as a curling iron by removing the movable hair-planting combs 5 on the comb mounting base 6, further increasing the function of the curling iron and expanding its application areas.

[0031] refer to Figures 1 to 6As shown, in actual use of the preferred embodiment of the present invention, after the power of the curling iron is turned on, the radial size of the cylindrical movable hair-planting comb 5 of the curling iron is adjusted by the motor drive. Generally speaking, the adjustable range of its radial size is designed to be 30-55mm. During use, the motor can be controlled to rotate forward and reverse at any time and stop at any position, so as to obtain radial dimensions of any angle to adapt to different curling styles. There is no need to replace the curling iron during use, which improves the efficiency of hair styling to a certain extent. At the same time, as mentioned above, the curling iron can be used as a curling rod by removing the movable hair-planting comb 5 from the comb mounting seat 6.
