[0024] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar elements, unless otherwise represented. The embodiments described in the following exemplary embodiments do not represent all the implementations in accordance with this disclosure. Instead, they only describe devices and methods in accordance with some aspects of this disclosure, as detailed in the appended claims.

[0025] In the related art, in order to ensure the stability of the wireless straightening comb when placed in the charging base, solve the problem that the wireless straightening comb is easy to fall when charging, a support structure is often provided on the charging base, and the straightening comb is placed in the charging base at an angle, and the charging base and the support structure jointly support the straightening comb, thereby improving the stability of the wireless straightening comb when placed in the charging base, but this also leads to a larger volume of the charging base, which is not convenient to place and carry.

[0026] In order to solve the above technical problems, according to an embodiment of the present disclosure, a charging device is provided for charging a straightening comb, the charging device comprising: a containing groove for containing at least a part of the straightening comb, the containing groove comprising a first bottom surface, the first bottom surface being a central symmetric figure; a plurality of first limiting portions, the plurality of first limiting portions being provided on the first bottom surface and limiting displacement of the straightening comb parallel to the first bottom surface, wherein the plurality of first limiting portions are symmetrically arranged about the geometric center of the first bottom surface.

[0027] This disclosure improves the stability of the hair straightener when placed in the charging device by providing a plurality of first limiting parts that are geometrically symmetrical about the first bottom surface of the charging device receiving slot, thereby allowing the hair straightener to be inserted and placed in the charging device in both directions.

[0028] Figure 1 This is a schematic diagram of the structure of a charging device according to an exemplary embodiment. Figure 2 This is a cross-sectional view of a charging device according to an exemplary embodiment.

[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, the charging device 100 may include a receiving slot 110 and a plurality of first limiting parts.

[0030] The receiving slot 110 can be a slot for accommodating a hair straightener. When the hair straightener is placed in the charging device 100 for charging, at least a portion of the hair straightener can be inserted into the receiving slot 110 for charging.

[0031] Multiple first limiting parts can be provided on the first bottom surface 111. The first limiting parts can restrict the straightening comb placed in the receiving groove 110 from moving in a direction parallel to the first bottom surface 111. This can improve the connection stability between the straightening comb and the charging device 100 when the straightening comb is charging, and reduce the situation of the straightening comb shaking or tipping over.

[0032] The receiving slot 110 may include a first bottom surface 111, which may be a centrally symmetrical shape, with multiple first limiting parts arranged symmetrically about the geometric center of the first bottom surface 111. This symmetrical configuration allows the straightener to be inserted into the receiving slot 110 for charging from either side, reducing the accuracy and directional requirements when placing the straightener on the charging device 100 and improving operational convenience.

[0033] This disclosure improves the stability of the hair straightener when it is placed in the charging device 100 by providing a plurality of first limiting parts that are geometrically symmetrical about the first bottom surface 111 of the receiving groove 110 of the charging device 100, thereby allowing the hair straightener to be inserted and placed in the charging device 100 in both directions.

[0034] In some embodiments, the receiving slot 110 can be elliptical, and the cross-sectional shape of the corresponding structure into which the straightener is inserted into the receiving slot 110 can also be elliptical. After the straightener is rotated 180 degrees and 360 degrees around the insertion direction, it can be normally inserted into the receiving slot 110 of the charging device 100. The elliptical cross-sectional shape of the corresponding structure into which the straightener is inserted into the receiving slot 110 makes it easier for the user to hold the straightener.

[0035] In some embodiments, the accommodation groove 110 can be circular, the cross-sectional shape of the corresponding structure into which the straight comb is inserted can also be circular, and the straight comb can be normally inserted into the accommodation groove 110 of the charging device 100 after being rotated by any angle around the insertion direction, thereby further reducing the operation accuracy and direction requirement when the straight comb is placed on the charging device 100.

[0036] The present disclosure is not limited thereto, and the accommodation groove 110 can also be other central symmetric figures to facilitate reducing the direction requirement for inserting the straight comb.

[0037] In some embodiments, the plurality of first limiting portions can include one or more of protrusions and recesses. By making the first limiting portions protrude or recess along the defense line perpendicular to the first bottom surface 111, displacement of the straight comb placed in the accommodation groove 110 in a direction parallel to the first bottom surface 111 can be limited, thereby improving the connection stability of the straight comb and the charging device 100 when the straight comb is charging, and reducing the situation of the straight comb shaking or toppling. In addition, the concave-convex structure is easy to cooperate and separate, and while improving the stability of the straight comb and the charging device 100, the insertion and removal resistance of the straight comb and the charging device 100 can also be reduced, and the difficulty of the user inserting and removing the straight comb can be reduced.

[0038] In other embodiments, the first limiting portion can also include one or more of buckles, flexible members, elastic members, or magnetic members.

[0039] In some embodiments, as shown in Figure 1 and Figure 2 The plurality of first limiting portions can include a first sub-limiting portion 121, and the number of the first sub-limiting portions 121 can be multiple. The plurality of first sub-limiting portions 121 can be arranged around the geometric center of the first bottom surface 111. By arranging the plurality of first sub-limiting portions 121 around the geometric center of the first bottom surface 111 of the accommodation groove 110, the first sub-limiting portions 121 can support the straight comb to be inserted in the charging device 100 in the normal and reverse directions, and can limit the displacement of the straight comb in a direction parallel to the first bottom surface 111 when the straight comb is placed in the charging device 100, thereby improving the stability of the straight comb and the charging device 100 in the circumferential direction.

[0040] In some embodiments, as shown in Figure 1 and Figure 2As shown, the plurality of first limiting portions can include a first sub-limiting portion 121, the first sub-limiting portion 121 being an annular limiting portion, and the first sub-limiting portion 121 being arranged around the geometric center of the first bottom surface 111. By arranging the annular limiting portion arranged on the first bottom surface 111 of the accommodating groove 110 around the geometric center of the first bottom surface 111, the first sub-limiting portion 121 can not only support the straightening comb to be inserted into the charging device 100 in the correct direction, but also can improve the stability of the straightening comb and the charging device 100 in the circumferential direction when the straightening comb is placed in the charging device 100, and the structural complexity of the first bottom surface 111 of the charging device 100 is reduced.

[0041] In some embodiments, as shown in Figure 1 and Figure 2 , the first sub-limiting portion 121 can be a groove, and the first sub-limiting portion 121 can include a first surface 1210, which can be a surface formed by recessing the first bottom surface 111, wherein in a direction away from the first surface 1210 and close to the first bottom surface 111, the cross-sectional area of the first sub-limiting portion 121 parallel to the first bottom surface 111 gradually increases. For example, the opening shape of the first sub-limiting portion 121 can be similar to the shape of the first surface 1210, and the area of the opening of the first sub-limiting portion 121 can be greater than the area of the first surface 1210. This can make the structure of the straightening comb more easily inserted into the first sub-limiting portion 121 when the straightening comb is inserted into the charging device 100, and reduce the accuracy requirement of the straightening comb inserted into the charging device 100.

[0042] In some embodiments, as shown in Figure 1 and Figure 2 , the plurality of first limiting portions can include a second sub-limiting portion 122, the second sub-limiting portion 122 being a central symmetric structure, and the geometric center of the second sub-limiting portion 122 coinciding with the geometric center of the first bottom surface 111. By arranging the second sub-limiting portion 122 as a central symmetric structure and coinciding the geometric center of the second sub-limiting portion 122 with the geometric center of the first bottom surface 111, the second sub-limiting portion 122 can not only support the straightening comb to be inserted into the charging device 100 in the correct direction, but also can further limit the displacement of the straightening comb in the direction parallel to the first bottom surface 111 when the straightening comb is placed in the charging device 100, and further improve the stability of the straightening comb and the charging device 100.

[0043] In some embodiments, as shown in Figure 1 and Figure 2As shown, the second sub-limiting portion 122 can be a protrusion, and the second sub-limiting portion 122 can include a second surface 1220, which can be a surface formed by the first protrusion of the first bottom surface 111. In a direction away from the second surface 1220 and close to the first bottom surface 111, the cross-sectional area of the second sub-limiting portion 122 parallel to the first bottom surface 111 gradually increases. For example, the second sub-limiting portion 122 can be a boss structure, and the lower bottom surface area of the second sub-limiting portion 122 is greater than the upper bottom surface area. This can make it easier for the straightening comb to be inserted into the second sub-limiting portion 122 when the straightening comb is inserted into the charging device 100, thereby reducing the accuracy requirement of the straightening comb when inserted into the charging device 100.

[0044] In some embodiments, as shown in Figure 1 and Figure 2 The charging device 100 further includes a plurality of first contacts 130, which can be arranged on the first bottom surface 111. The charging device 100 can output an electric current to the outside via the first contacts 130 to charge the straightening comb electrically connected to the first contacts 130.

[0045] The first contacts 130 can be symmetrically arranged about the geometric center of the first bottom surface 111, so that the straightening comb can be charged when inserted in either direction, thereby reducing the operation accuracy and direction requirement when the straightening comb is placed on the charging device 100.

[0046] In some embodiments, as shown in Figure 1 and Figure 2 The accommodation groove 110 further includes a guide structure 140, which can be arranged on the side wall of the accommodation groove 110. The guide structure 140 can be a protrusion structure extending in the depth direction of the accommodation groove 110. For example, the guide structure 140 can be four and uniformly distributed on the side wall of the accommodation groove 110.

[0047] The guide structure 140 can guide the straightening comb when inserted into the charging device 100 and limit the rotation of the straightening comb in the accommodation groove 110, thereby improving the stability of the straightening comb in the accommodation groove 110.

[0048] In some embodiments, as shown in Figure 1 and Figure 2 The opening of the accommodation groove 110 is provided with a curved surface structure, which can be used to limit the movement of the straightening comb and make the straightening comb slide along the curved surface structure and be inserted into the accommodation groove 110, thereby reducing the accuracy requirement of the straightening comb when inserted into the charging device 100.

[0049] Based on the same concept, the disclosure also provides a straightening comb, which can be charged by the charging device 100. The straightening comb can be any beauty device for hair styling.

[0050] Figure 3 FIG. 1 is a structural schematic diagram of a straightening comb according to an exemplary embodiment. Figure 4 FIG. 2 is a structural schematic diagram of a second bottom surface of a straightening comb according to an exemplary embodiment. Figure 5 FIG. 3 is a structural schematic diagram of a second bottom surface of a straightening comb according to an exemplary embodiment.

[0051] In some embodiments, as shown in FIG. 1, the straightening comb 200 can include a housing 210 and a plurality of second limiting portions. Figures 3-5

[0052] The housing 210 can be an outer shell of the straightening comb 200. The housing 210 can include a second bottom surface 211, and the plurality of second limiting portions can be disposed on the second bottom surface 211 and limit displacement of the straightening comb 200 in a direction parallel to the second bottom surface 211. Thus, when the straightening comb 200 is being charged, the connection stability of the straightening comb 200 and the charging device 100 can be improved, and the shaking or tilting of the straightening comb 200 can be reduced.

[0053] The second bottom surface 211 can be a center-symmetric figure, and the second bottom surface 211 can have the same shape as the first bottom surface 111. The plurality of second limiting portions can be symmetrically disposed about the geometric center of the second bottom surface 211. Through the above symmetric configuration, the straightening comb 200 can be inserted into the accommodation slot 110 for charging in both directions, the operation accuracy and direction requirement when placing the straightening comb 200 on the charging device 100 can be reduced, and the operation convenience can be improved.

[0054] The present disclosure improves the stability of the straightening comb 200 when placed on the charging device 100 by disposing the plurality of first limiting portions symmetrically about the geometric center of the first bottom surface 111 of the accommodation slot 110 of the charging device 100, and disposing the plurality of second limiting portions symmetrically about the geometric center of the second bottom surface 211 of the straightening comb 200.

[0055] Figure 6 FIG. 1 is a structural schematic diagram of a straightening comb and a charging device according to an exemplary embodiment.

[0056] In some embodiments, as shown in FIG. 1, the straightening comb 200 can include a housing 210 and a plurality of second limiting portions. Figure 3 and Figure 6 ​As shown, the housing 210 can include a handle portion 212, at least a portion of the handle portion 212 is inserted into the receiving groove 110 when the straightening comb 200 is inserted into the charging base, and the second bottom surface 211 can be an end surface of the handle portion 212. By arranging the limiting structure and the charging terminal in this way, the product length direction of the straightening comb 200 can be parallel to the horizontal direction, and the design of the straightening comb 200 being vertically placed on the charging device 100 can be achieved, thereby eliminating the need for an inclined support structure of the charging base, and thus reducing the volume of the straightening comb 200 and the charging device 100, and reducing the total space occupied by the straightening comb 200 when placed on the charging device 100.

[0057] In some embodiments, the receiving groove 110 can be oval-shaped, and the cross-sectional shape of the handle portion 212 can also be oval-shaped, so that the handle portion 212 can be normally inserted into the receiving groove 110 of the charging device 100 after the straightening comb 200 is rotated by 180 degrees or 360 degrees around the insertion direction. Designing the cross-sectional shape of the handle portion 212 to be oval-shaped can facilitate the user to hold the handle portion 212 of the straightening comb 200.

[0058] In some embodiments, the receiving groove 110 can be circular, and the cross-sectional shape of the handle portion 212 can also be circular, so that the handle portion 212 can be normally inserted into the receiving groove 110 of the charging device 100 after the straightening comb 200 is rotated by any angle around the insertion direction, thereby further reducing the operation accuracy and direction requirement when placing the straightening comb 200 on the charging device 100.

[0059] In some embodiments, as shown in Figure 4 and Figure 5 The plurality of second limiting portions can include one or more of protrusions and recesses, and by making the second limiting portions protrude or recess along a line of defense perpendicular to the second bottom surface 211, displacement of the straightening comb 200 placed in the receiving groove 110 in a direction parallel to the second bottom surface 211 can be limited, thereby improving the connection stability of the straightening comb 200 and the charging device 100 when the straightening comb 200 is charging, and reducing the shaking or tilting of the straightening comb 200. In addition, the concave-convex structure is easy to cooperate and separate, which can improve the stability of the straightening comb 200 and the charging device 100, while reducing the plugging resistance of the straightening comb 200 and the charging device 100, and reducing the difficulty of the user plugging the straightening comb 200.

[0060] In other embodiments, the second limiting portion can also include one or more of buckles, flexible members, elastic members, or magnetic members.

[0061] In some embodiments, as shown in Figure 5 and Figure 6The plurality of second limiting portions can include third sub-limiting portions 221, and the number of the third sub-limiting portions 221 can be multiple. The plurality of third sub-limiting portions 221 are arranged around the geometric center of the second bottom surface 211. By arranging the plurality of second sub-limiting portions 122 arranged on the second bottom surface 211 of the accommodating groove 110 around the geometric center of the second bottom surface 211, the second sub-limiting portions 122 can not only support the straightening comb 200 to be inserted into the charging device 100 in the forward and reverse directions, but also limit the displacement of the straightening comb 200 in the direction parallel to the second bottom surface 211 when the straightening comb 200 is placed in the charging device 100, thereby improving the stability of the straightening comb 200 and the charging device 100 in the circumferential direction.

[0062] In some embodiments, as shown in Figure 5 and Figure 6 The plurality of second limiting portions can include third sub-limiting portions 221, and the third sub-limiting portions 221 can be annular limiting portions. The third sub-limiting portions 221 are arranged around the geometric center of the second bottom surface 211. By arranging the annular limiting portions arranged on the second bottom surface 211 of the accommodating groove 110 around the geometric center of the second bottom surface 211, the second sub-limiting portions 122 can not only support the straightening comb 200 to be inserted into the charging device 100 in the forward and reverse directions, but also improve the stability of the straightening comb 200 and the charging device 100 in the circumferential direction when the straightening comb 200 is placed in the charging device 100, and reduce the structural complexity of the second bottom surface 211 of the straightening comb 200.

[0063] In some embodiments, as shown in Figure 5 and Figure 6 The third sub-limiting portions 221 can be protrusions. The third sub-limiting portions 221 as protrusions can abut against the first sub-limiting portions 121 as grooves and limit the displacement of the straightening comb 200 in the direction parallel to the second bottom surface 211. In addition to improving the stability of the straightening comb 200 and the charging device 100, the third sub-limiting portions 221 can also reduce the plugging resistance of the straightening comb 200 and the charging device 100, thereby reducing the difficulty of the user plugging the straightening comb 200.

[0064] In some embodiments, as shown in Figure 5 and Figure 6The plurality of second limiting portions can include a fourth sub-limiting portion 222, which is a central symmetric structure, and the geometric center of the fourth sub-limiting portion 222 can coincide with the geometric center of the second bottom surface 211. By setting the second sub-limiting portion 122 as a central symmetric structure and coinciding the geometric center of the second sub-limiting portion 122 with the geometric center of the second bottom surface 211, the second sub-limiting portion 122 can not only support the straightening comb 200 to be inserted and placed in the charging device 100 in both directions, but also further limit the displacement of the straightening comb 200 in the direction parallel to the second bottom surface 211 when the straightening comb 200 is placed in the charging device 100, thereby further improving the stability of the straightening comb 200 and the charging device 100.

[0065] In some embodiments, the straightening comb 200 can include a port assembly 223, and the fourth sub-limiting portion 222 can be a groove. The port assembly 223 can be arranged in the fourth sub-limiting portion 222. By arranging the port assembly 223 in the fourth sub-limiting portion 222, the reuse of the groove structure is achieved, the number of grooves on the surface of the shell 210 is reduced, and the aesthetics of the straightening comb 200 is improved.

[0066] For example, the port assembly 223 can be a universal serial bus interface.

[0067] In some embodiments, as Figure 5 and Figure 6 The charging device 100 further includes a plurality of second contacts 230, which can be arranged on the second bottom surface 211. After the straightening comb 200 is inserted into the charging device 100, the first contacts 130 can be electrically connected with the second contacts 230, and the straightening comb 200 can receive current through the first contacts 130 and the second contacts 230 to be charged.

[0068] The second contacts 230 can be symmetrically arranged about the geometric center of the second bottom surface 211, so that the straightening comb 200 can be charged when inserted in both directions, thereby reducing the operation accuracy and direction requirement when the straightening comb 200 is placed on the charging device 100.

[0069] The present disclosure improves the stability of the straightening comb 200 when placed in the charging device 100 by arranging a plurality of first limiting portions symmetrically about the geometric center of the first bottom surface 111 of the accommodation groove 110 of the charging device 100, and arranging a plurality of second limiting portions symmetrically about the geometric center of the second bottom surface 211 of the straightening comb 200.
