Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing devices, in particular to a straight and curly dual-purpose hair styling device. Background Art

[0002] With the improvement of people's material life, beauty and hairdressing has become a major consumer field, and various appliances for beauty and hairdressing have also emerged, including hair straighteners, hair curlers, etc. As the name suggests, a hair straightener is an appliance for straightening hair, and a hair curler is an appliance for shaping and curling hair. Among the existing products, the functions are relatively single, that is, they can only independently realize the straightening function or the curling function, which cannot meet the user's needs for various styling.

[0003] In order to solve the technical defect of the current curling irons and hair straighteners having a single function, many hair styling devices for both straightening and curling have appeared on the market. Such hair styling devices for both straightening and curling mainly have a heatable styling component rotatably installed on an upper handle and a lower handle, and the styling component is driven to rotate by a driving component such as a rotating shaft, so that the styling component can be switched from a horizontal state to a vertical state, thereby enabling the hair styling device to switch between a straight hair working mode and a curling hair working mode.

[0004] The inventor discovered during the actual research and development process that most of the current hair styling devices that can be used for both straightening and curling use a fixed connection between the rotating shaft and the styling component, and then the styling component is driven to rotate by rotating the rotating shaft to switch between the straightening working mode and the curling working mode; however, a large amount of heat is generated when the styling component is working, and thermal expansion and contraction problems will occur when it is not working, resulting in misalignment between the styling component and the rotating shaft; if misalignment occurs, the rotating shaft and the styling component are not arranged on the same axis, and at this time, the styling component will be stuck when driven to rotate by the rotating shaft, which seriously affects the reliability of the styling device.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] Please also read Figures 1 to 9 The straight and curly dual-purpose hair styling device provided in the embodiment of the present application is now described. The straight and curly dual-purpose hair styling device 10 comprises: an upper handle 11, a lower handle 12 and a heating component 13.

[0040] The upper handle 11 and the lower handle 12 are hinged at the same end, and there are at least two heating components 13, one of which is installed on the upper handle 11 and the other is installed on the lower handle 12, and both heating components 13 are rotatably installed. The upper handle 11 and the lower handle 12 can both be rotatably installed with a first rotating shaft 14, and the first rotating shaft 14 is installed with a connecting member, and the heating component 13 is driven to rotate through the connecting member to switch different angles. The connecting member includes a first connecting member 15 and a second connecting member 16 that is movably installed on the first connecting member 15. When the heating component 13 and the first rotating shaft 14 have a position deviation, the first connecting member 15 can be displaced relative to the second connecting member 16 to reduce the position deviation.

[0041] Specifically, by providing a first connecting member and a second connecting member that can be displaced relative to the first connecting member, the first connecting member is installed on the first rotating shaft, and the second connecting member is installed on the heating component; when a position deviation occurs between the first rotating shaft and the heating component, the second connecting member can be displaced relative to the first connecting member to eliminate the position deviation between the first rotating shaft and the heating component, thereby ensuring that when the first rotating shaft drives the heating component to rotate, it will not get stuck due to the position deviation, thereby improving the reliability of the heating component in switching between the straight hair mode and the curly hair mode.

[0042] Please also read Figures 3 to 9 In some embodiments of the present application, the first connecting member 15 can be rotatably installed on one end of the first rotating shaft 14; the second connecting member 16 can be movably installed on the first connecting member 15, and the second connecting member 16 is fixedly connected to the heating component 13; when the first rotating shaft 14 is rotated, the first connecting member 15 and the second connecting member 16 can be driven to rotate synchronously to drive the heating component 13 to rotate and switch to different angles.

[0043] Specifically, since the first connecting member 15 can be rotatably installed on the first rotating shaft 14, and the second connecting member 16 can be movably installed on the first connecting member 15; therefore, there is a floating connection structure between the first connecting member 15 and the second connecting member 16; when the second connecting member 16 is connected to the heating component 13 for transmission, the floating connection effect between the first connecting member 15 and the second connecting member 16 can be utilized, thereby eliminating the possible position deviation and misalignment problem between the first rotating shaft 14 and the heating component 13, thereby ensuring that the first rotating shaft 14 can normally and reliably drive the heating component 13 to rotate without jamming.

[0044] In more detail, the first connecting member 15 is provided with a first rotating protrusion 151, and the first rotating shaft 14 is provided with a first rotating groove 141 for the first rotating protrusion 151 to be inserted into. The first connecting member 15 can rotate relative to the first rotating shaft 14 with the central axis of the first rotating protrusion 151 as the central rotating point.

[0045] Preferably, the first connecting member 15 is provided with a first limiting notch 152, and the first rotation protrusion 151 is provided on the side of the first limiting notch 152; after one end of the first rotating shaft 14 is inserted into the first limiting notch 152, the first rotation protrusion 151 can be inserted into the first rotating groove 141. Such a structure can improve the connection reliability between the first rotating shaft 14 and the first connecting member 15, and it is not easy to loosen.

[0046] In other embodiments of the present application, the second connecting member 16 is provided with a second limiting groove 161, and the first connecting member 15 is provided with a first limiting protrusion 153 that can adapt to the second limiting groove 161; when the first limiting protrusion 153 is inserted into the second limiting groove 161, the second connecting member 16 can be displaced along the extension direction of the first limiting protrusion 153.

[0047] Specifically, when the first limiting convex strip 153 is horizontally arranged, the second connecting member 16 can be horizontally displaced relative to the first connecting member 15; when the first limiting convex strip 153 is vertically arranged, the second connecting member 16 can be vertically displaced relative to the first connecting member 15. In other words, when the first connecting member 15 and the second connecting member 16 are switched to different angles, the second connecting member 16 can be displaced relative to the first connecting member 15, thereby eliminating the position deviation problem between the first rotating shaft and the heating component 13.

[0048] Exemplarily, when the first rotating shaft 14 drives the heating component 13 to switch to the straight-hair working mode, the heating plate 131 of the heating component 13 is arranged in a horizontal state; at this time, the first connecting member 15 can swing up and down relative to the first rotating shaft 14, that is, it swings up and down in the vertical plane direction with the central axis of the first rotating protrusion 151 as the center; at the same time, the first limiting convex strip 153 is extended in the horizontal plane direction, and the second limiting hook 161 can move horizontally along the extension direction of the first limiting convex strip 153; it can be seen that when the heating component 13 is in the straight-hair working mode, the first connecting member 15 can reduce the position deviation in the vertical plane direction between the heating component 13 and the first rotating shaft 14, and the second connecting member 16 can reduce the position deviation in the horizontal plane direction between the heating component 13 and the first rotating shaft 14; accordingly, when there is a deviation in the spacing distance between the heating component 13 and the first rotating shaft 14, it can also be reduced by the swing of the first connecting member 15.

[0049] Next, when the first rotating shaft 14 drives the heating component 13 to switch to the curling working mode, the heating plate 131 of the heating component 13 is set in a vertical state; at this time, the first connecting member 15 can swing left and right relative to the first rotating shaft 14, that is, it swings left and right in the horizontal plane direction with the central axis of the first rotating protrusion 151 as the center; at the same time, the first limiting convex strip 153 is extended in the vertical plane direction, and the second limiting hook 161 can move vertically along the extension direction of the first limiting convex strip 153; it can be seen that when the heating component 13 is in the curling working mode, the first connecting member 15 can reduce the position deviation of the heating component 13 and the first rotating shaft 14 in the horizontal plane direction, and the second connecting member 16 can reduce the position deviation of the heating component 13 and the first rotating shaft 14 in the vertical plane direction; accordingly, when there is a deviation in the spacing distance between the heating component 13 and the first rotating shaft 14, it can also be reduced by the swing of the first connecting member 15.

[0050] It can be understood that by providing the first connecting member 15 and the second connecting member 16, the position deviation problem between the heating component 13 and the first rotating shaft 14 can be eliminated when the heating component 13 is switched to the straight hair working mode or the curling hair working mode, thereby ensuring that the first rotating shaft 14 can normally drive the heating component 13 to switch to different working modes, eliminating the problem of jamming and improving the reliability of use.

[0051] In other embodiments of the present application, the heating component 13 includes a heating plate 131 and end caps 132 installed at two ends of the heating plate 131, and the end caps 132 can be rotatably installed on the upper handle 11 or the lower handle 12. The heating plate 131 can be installed with electric heating elements, such as PTC heating elements, heating wires, thermistors, conductive coatings, electric heating films, etc., and the heating plate 131 can be heated by the electric heating elements to perform straight hair styling or curly hair styling.

[0052] Specifically, the upper handle 11 and the lower handle 12 are also installed with an articulated bracket 17 and a gear set 18, and one end cover 132 of the heating plate 131 can be rotatably installed on the articulated bracket 17, and the other end cover 132 can be rotatably installed on the gear set 18. The gear set 18 is provided with a first tooth portion 181 and a second tooth portion 182 that mesh with each other, the first tooth portion 181 is provided on the end cover 132, and the second tooth portion 182 is provided on the second connecting member 16.

[0053] Preferably, both end covers 132 are provided with a first hinge shaft 133, wherein one first hinge shaft 133 can be rotatably mounted on the hinge bracket 17, and the other first hinge shaft 133 can be rotatably mounted on the gear set 18, and the first tooth portion 181 is provided on the first hinge shaft 133 rotatably mounted on the gear set 18; accordingly, the second connecting member 16 can be rotatably mounted on the gear set 18, and the second tooth portion 182 is meshed and connected with the first tooth portion 181.

[0054] It should be noted here that in order to enable the first hinge shaft 133 to be rotatably installed, the hinge bracket 17 and the gear set 18 are both provided with holes for rotatably installing the first hinge shaft 133. The assembly of the shaft and the hole is a conventional design method for those skilled in the art, and the specific structure will not be described one by one.

[0055] During operation, the first rotating shaft 14 rotates, which can drive the first connecting member 15 and the second connecting member 16 to rotate synchronously, and the second tooth portion 182 rotates synchronously. At this time, since the second tooth portion 182 is meshed and connected with the first tooth portion 181, it can drive the heating component 13 to rotate and switch the straight hair working mode or the curling hair working mode.

[0056] In more detail, the first knob 19 is rotatably mounted on one end of the upper handle 11 and the lower handle 12 which are hinged together, and the first knob 19 can drive the first rotating shaft 14 to rotate. The other end of the first rotating shaft 14 is hinged with a third tooth portion 142, and the first knob 19 is provided with a fourth tooth portion 191 meshing with the third tooth portion 142; with such a structure, the first knob 19 can be used to drive the first rotating shaft 14 to rotate when the upper handle 11 and the lower handle 12 are relatively opened or relatively closed.

[0057] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
