Description

Technical Field

[0001] The utility model relates to a hair curler for curling and curling hair, in particular to a hair curler assembly with a hair curler having an adjustable diameter and a hair curler comprising the hair curler assembly. Background Art

[0002] The curling iron at least comprises a handle and a curling roller assembly that can generate heat. The temperature of the curling roller of the curling roller assembly that can generate heat can be controlled by an electric control device. The curling roller of the curling roller assembly is usually made of materials such as tourmaline, ceramics or titanium alloy, so that the curling roller can generate heat evenly, thereby creating a bend and protecting the hair quality by improving the protein structure of the hair during the curling process. For a manual curling iron, the user needs to manually wrap the hair to be styled around the curling roller in one or more turns during use. For an automatic curling iron, the user turns on a switch to start the motor to drive the rotating drum to rotate relative to the curling roller, thereby wrapping the hair to be styled around the curling roller in one or more turns.

[0003] In order to make the curling shape of hair diversified, rich in layering and more beautiful, a diameter-adjustable curling roller has been proposed, and the diameter of this curling roller can be changed between a minimum size and a maximum size so that the hair can have a curling shape with different curvature radii. This diameter-adjustable curling roller includes at least two (usually three) heat-conducting members, each of which includes a first extension formed on one longitudinal edge and a second extension formed on another longitudinal edge. Each heat-conducting member is radially movably mounted on a first support seat at one longitudinal end and radially movably mounted on a second support seat at another longitudinal end, so that a plurality of heat-conducting members are enclosed to form a curling roller. Regardless of the diameter state, the first extension of each heat-conducting member and the second extension of the adjacent heat-conducting member always overlap each other in the circumferential direction of the curling roller. In this way, it is possible to prevent the adjacent heat-conducting members from forming a gap along the longitudinal direction when the diameter of the curling roller is adjusted, thereby preventing the hair from being sandwiched between the adjacent heat-conducting members.

[0004] However, since the heat-conducting member is radially movably mounted on the support seat at the longitudinal end, there is a gap between the longitudinal end of the heat-conducting member and the support seat to a greater or lesser extent, and hair can be easily caught in the gap. In order to make it easy to take the hair out of the gap between the longitudinal end of the heat-conducting member and the support seat, the existing solution tends to increase the size of the gap, but this not only allows foreign matter to enter the interior of the curling barrel assembly or get stuck in the gap, but also makes the entire curling iron look crudely made and cheap.

[0005] Therefore, there is a need to improve the existing hair roller assembly with adjustable diameter hair roller. Utility Model Content

[0006] The purpose of the utility model is to overcome the defects in the above-mentioned prior art and provide a hair roller assembly with a hair roller with adjustable diameter and a hair curler including such a hair roller assembly, wherein the hair roller assembly can prevent hair from entering the gap between the longitudinal end of the heat conductor and the support seat to prevent hair from being clamped in the gap. At the same time, since there is no problem of hair being clamped, the gap between the longitudinal end of the heat conductor and the support seat can be minimized to prevent foreign matter from entering the interior of the hair roller assembly or being stuck in the gap.

Since the risk of hair being caught between the first connecting member and the first support seat is eliminated, the gap between the longitudinal end of the heat conductive member and the support seat can be minimized, thereby improving the workmanship accuracy and preventing foreign matter from entering the interior of the hair roller assembly or getting stuck in the gap.

[0038] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the accompanying drawings are only used to illustrate the present invention and do not constitute a limitation to the present invention.

[0039] Figure 1 The hair roller assembly with a hair roller with adjustable diameter according to the present invention is schematically shown in a three-dimensional view, wherein the hair roller is adjusted to a state with a minimum diameter. Figure 2 The hair roller assembly with a hair roller with adjustable diameter according to the present invention is schematically shown in a three-dimensional view, wherein the hair roller is adjusted to a state with a maximum diameter. Figure 3 2 is an exploded perspective view of a hair roller assembly with an adjustable diameter according to the utility model. Figure 1-3 As shown, the hair roller assembly 1 with a hair roller having an adjustable diameter according to the utility model generally includes at least two elongated heat-conducting members 3, each of which has a heat-conducting body 3b forming a longitudinal central cavity 3a, a first extension 3c formed on one longitudinal edge of the heat-conducting body 3b, and a second extension 3d formed on the other longitudinal edge of the heat-conducting body 3b. A heating element 5 that generates heat when powered on is arranged in the central cavity 3a of each heat-conducting member 3. The hair roller assembly 1 also includes a first support seat 7, a second support seat 9, and a hollow support column 11 connecting the first support seat 7 and the second support seat 9 together. A first concave cavity 7a is formed in the center of the first support seat 7, and a second concave cavity ( Figure 3 The ends of the hollow support column 11 are respectively installed in the first cavity 7a and the second cavity. The ends of the hollow support column 11 are preferably installed in the first cavity and the second cavity by shape matching. For example, the hollow support column 11 can be formed to have a generally triangular cross-section, and the first cavity and the second cavity are also formed as generally triangular cavities.

[0040] The first support seat 7 is also formed with a first radially extending hole 7b corresponding to each heat-conducting member 3, and the second support seat 9 is also formed with a second radially extending hole 9b corresponding to each heat-conducting member 3. Each heat-conducting member 3 is mounted on the first support seat 7 through the first connecting member 13 at one end, and each heat-conducting member 3 is mounted on the second support seat 9 through the second connecting member 15 at the other end. Each first connecting member 13 includes a mounting portion 13b protruding from one side of the body portion 13a and a first guide shaft 13c protruding from the opposite side of the body portion 13a and the mounting portion 13b. The mounting portion 13b of the first connecting member 13 can be inserted into the central cavity 3a of the heat-conducting member 3, so that the end of the heat-conducting member 3 abuts against the body portion 13a of the first connecting member 13 and the heat-conducting member 3 is preferably fixedly connected to the mounting portion 13b by screws. The second connecting member 15 has a structure substantially the same as the first connecting member 13 and is fixedly connected to the other end of the heat-conducting member 3 in the same manner. Each heat-conducting member 3 is formed by inserting the first guide shaft 13c of the first connecting member 13 fixedly connected thereto into the first radially extending hole 7b corresponding to the first supporting seat 7, and inserting the second guide shaft 15c of the second connecting member 15 fixedly connected thereto into the second radially extending hole 9b corresponding to the second supporting seat 9, so that multiple heat-conducting members 3 surround the hollow supporting column 11 to form a hair curler 17. The outer side surface of the heat conductor 3b of the heat-conducting member 3 is preferably arc-shaped, so that the hair curler 17 formed by the multiple heat-conducting members 3 is generally cylindrical.

[0041] The hair roller assembly 1 further comprises a driving mechanism for radially moving the heat-conducting member 3 relative to the first support seat and the second support seat to adjust the diameter of the hair roller 17. Preferably, the driving mechanism may comprise a central shaft 19 extending through the hollow support column 11, the first support seat 7 and the second support seat 9, and a first driving plate 21 and a second driving plate 23 fixedly mounted at both ends of the central shaft 19 so as to be able to rotate with the central shaft 19. The first driving plate 21 is formed with a plurality of first arc-shaped holes 21a corresponding to the heat-conducting member 3, and the distance from each first arc-shaped hole 21a to the center of the first driving plate 21 is gradually changing. The second driving plate 23 has the same structure as the first driving plate 21, and thus, the second driving plate 23 is also formed with a plurality of second arc-shaped holes 23a corresponding to the heat-conducting member 3, and the distance from each second arc-shaped hole 23a to the center of the second driving plate 23 is gradually changing. The first guide shaft 13c of the first connecting member 13 passing through the first radially extending hole 7b of the first supporting seat 7 also passes through the corresponding first arc-shaped hole 21a on the first driving plate 21, and the second guide shaft 15c of the second connecting member 15 passing through the second radially extending hole 9b of the second supporting seat 9 also passes through the corresponding second arc-shaped hole 23a on the second driving plate 23. The hair curler generally further includes an adjusting element (not shown in the figure) for driving the central shaft 19 to rotate. In this way, by operating the adjusting element, the central shaft 19 can be driven to rotate, thereby causing the first driving plate 21 and the second driving plate 23 to rotate together with the central shaft 19. Since the first guide shaft 13c of the first connecting member 13 fixedly connected to the heat-conducting member 3 passes through the first radially extending hole 7b of the first supporting seat 7 and the first arc-shaped hole 21a on the first driving plate 21 at the same time, the second guide shaft 15c of the second connecting member 15 fixedly connected to the heat-conducting member 3 passes through the second radially extending hole 9b of the second supporting seat 9 and the second arc-shaped hole 23a on the second driving plate 23 at the same time, and the distance from each first arc-shaped hole 21a to the center of the first driving plate 21 is gradually changing, and the distance from each second arc-shaped hole 23a to the center of the second driving plate 23 is gradually changing, therefore, when When the first driving plate 21 and the second driving plate 23 rotate together with the central shaft 19 in one direction, each heat-conducting member 3 is caused to move radially outward through the first guide shaft 13c and the second guide shaft 15c to increase the diameter of the hair roller 17 surrounded by the plurality of heat-conducting members 3; when the first driving plate 21 and the second driving plate 23 rotate together with the central shaft 19 in a direction opposite to the one direction, each heat-conducting member 3 is caused to move radially inward through the first guide shaft 13c and the second guide shaft 15c to reduce the diameter of the hair roller 17 surrounded by the plurality of heat-conducting members 3. The first extension portion 3c of each heat-conducting member 3 and the second extension portion 3d of the adjacent heat-conducting member always overlap closely with each other in the circumferential direction of the hair roller 17, so as to prevent the adjacent heat-conducting members 3 from forming a gap in the longitudinal direction during the process of adjusting the diameter of the hair roller 17, thereby preventing the hair from being sandwiched between the adjacent heat-conducting members 3.An upper cover 25 may also be included, which can be snapped onto the second support base 9 to prevent the second driving plate 23 from being exposed.

[0042] According to the utility model, each first connector 13 also includes a flange 13d arranged on the periphery of the body portion 13a and protruding from the body portion 13a along the same direction as the mounting portion 13b (i.e., along a direction parallel to the longitudinal direction of the heat conductor). When the first connector 13 is mounted on the heat conductor 3, the flange 13d is in close contact with the outer side of the heat conductor. Accordingly, a first groove 7c is formed around each first radially extending hole 7b on the first support seat 7, i.e., each first radially extending hole 7b is located at the bottom of the corresponding first groove 7c. When the heat conductor 3 is installed in place between the first support seat 7 and the second support seat 9, the flange 13d of each first connector 13 is received in the corresponding first groove 7c and can move therein with the heat conductor. Therefore, the top surface 8 of the part of the side wall of the first support seat 7 defining the first groove 7c has a height raised relative to the contact surface between the flange 13d of the first connecting member 13 and the first support seat 7. When the user is curling the hair, the hair will generally fall on the top surface 8 of the first support seat 7, and will not fall on the plane where the gap between the bottom side of the flange 13d of the first connecting member 13 and the first support seat 7 is located. Therefore, the part of the side wall of the first support seat 7 defining the first groove 7c can prevent the hair from falling into the gap between the bottom side (i.e., the side close to the first support seat) of the flange 13d of the first connecting member 13 and the first support seat 7, thereby preventing the hair from being caught in the gap between the bottom side of the flange 13d of the first connecting member 13 and the first support seat 7. Preferably, the depth of the first groove 7c is equal to or greater than the height of the flange 13d of the first connecting member 13, thereby more effectively preventing the hair from falling into the gap between the bottom side of the flange 13d of the first connecting member 13 and the first support seat 7. Preferably, the first groove 7c is in the shape of a trumpet that opens toward the center of the first support seat, so as to minimize the gap between the outer side of the flange 13d of the first connecting member 13 and the first support seat 7, so as to further prevent hair from falling into the gap between the bottom side of the flange 13d of the first connecting member 13 and the first support seat 7.

[0043] In addition, a guide portion 13e extending radially outward may also be formed on the bottom side of the flange 13d of the first connecting member 13 (i.e., the side close to the first supporting seat), and a guide groove 7e is correspondingly formed on the bottom surface 7d of the first groove 7c of the first supporting seat 7. The guide portion 13e of the first connecting member 13 may be received in the guide groove 7e of the first supporting seat 7 so that each heat-conducting member 3 can be moved radially in the process of adjusting the diameter of the curling roller 17. Preferably, the guide portion 13e is formed substantially aligned with the first guide shaft 13c in the radial direction, and therefore, the guide groove 7e is formed radially around the first radially extending hole 7b. In addition, a circumferential hole 7f may be formed on the circumferential wall of the first groove 7c defined by the first supporting seat 7, and the circumferential hole 7f leads to the guide groove 7e, and in the process of moving the heat-conducting member 3 radially outward, the guide portion 13e may be as shown. Figure 2 The movement shown passes through the circumferential hole 7f, so that the diameter of the adjusted hair roller can be increased as much as possible without increasing the size of the first support seat 7.

[0044] Since the hair will droop under the action of gravity during the process of curling the hair with the curling iron, the hair will be clamped in the gap between the bottom side of the heat-conducting member 3 and the first support seat 7, so in the preferred embodiment, a protruding flange 13d is provided on the outer periphery of the body portion 13a of the first connecting member 13 mounted on the bottom side of the heat-conducting member 3, and a corresponding first groove 7c is provided on the first support seat 7. It should be understood that, although not shown, if necessary, a protruding flange can also be provided on the outer periphery of the body portion of the second connecting member 15 mounted on the top side of the heat-conducting member 3, and a corresponding second groove can be provided on the second support seat 9. Of course, the top side of the flange of the second connecting member 15 can also be formed with a guide portion extending radially outward, and a guide groove is formed on the bottom surface of the second groove of the second support seat 9 correspondingly.

[0045] In a preferred embodiment, the flange 13d protrudes from the body portion 13a of the first connector 13 and is in close contact with the outer side of the heat conductor 3 when the first connector 13 is mounted on the heat conductor 3, so that the gap between the body portion 13a and the heat conductor 3 is blocked, and thus hair will not be caught in the gap between the body portion 13a and the heat conductor 3. Although there may be a gap between the flange 13d and the heat conductor 3, the gap between the flange 13d and the heat conductor 3 is formed along the circumferential direction of the heat conductor 3 and the flange 13d is in close contact with the heat conductor 3, so the possibility of hair being caught in the gap between the flange 13d and the heat conductor 3 is relatively small. It should be understood that it is also feasible that the flange 13d is not formed on the outer periphery of the body portion 13a of the first connector 13, so that the body portion 13a of the first connector 13 is received in the corresponding first groove 7c and can move therein with the heat conductor. In this case, a tight connection can be formed between the heat conductor 3 and the main body 13a of the first connecting member 13, and the top surface 8 of the portion of the side wall of the first support seat 7 defining the first groove 7c has an elevated height relative to the contact surface between the main body 13a of the first connecting member 13 and the first support seat 7. Therefore, the portion of the side wall of the first support seat 7 defining the first groove 7c can also prevent hair from falling into the gap between the bottom side of the main body 13a of the first connecting member 13 (i.e., the side close to the first support seat) and the first support seat 7, thereby preventing hair from being clamped in the gap between the bottom side of the main body 13a of the first connecting member 13 and the first support seat 7.

[0046] Figure 8 The hair roller assembly and the rotating drum of the hair curler according to the present invention are schematically shown in a three-dimensional view. Figure 8 The curling iron shown in the figure is an automatic curling iron. Since the utility model does not involve improvements to other parts of the automatic curling iron, Figure 8 Many components of the automatic curling device are omitted, for example, the handle portion installed under the first support seat 7 and used to accommodate the motor and the electric control element for controlling the motor and the heating element, and the outer shell portion surrounding the rotating drum. Figure 8 As shown, the curling iron also includes a bearing ( Figure 8The rotating drum 27 is mounted on the first supporting seat 7 (not visible in the figure), for example, the inner roll of the bearing is mounted on the first supporting seat 7, the rotating drum 27 is mounted on the outer ring of the bearing, and the rotating drum 27 is also fastened to the gear 29. The rotating drum 27 is not a complete cylinder, but is formed with a longitudinal opening 27a, and a plurality of silicone pressing plates 31 are installed on the inner wall of the rotating drum. When in use, the user can put the hair from the top edge of the rotating drum 27 down against the curling roller 17 through the longitudinal opening 27a, and the pressing plate 31 presses the hair against the curling roller 17. When the switch of the curling iron is turned on, the pinion on the output shaft of the motor drives the gear 29 to rotate, and then drives the rotating drum 27 to rotate around the curling roller 17, so that the hair is rolled around the heated curling roller 17 to curl the hair and form a curved shape.

[0047] although Figure 8 The hair roller assembly with adjustable diameter of the hair roller according to the present invention is shown to be used in an automatic hair roller, but it should be understood that the hair roller assembly with adjustable diameter of the hair roller according to the present invention can also be used in a manual hair roller. In the latter case, the hair roller assembly is directly mounted on the handle portion equipped with the electric control element, and the user can manually roll the hair on the hair roller.

[0048] Although the present invention has been described in detail in conjunction with the preferred embodiments of the present invention, it should be understood that such detailed description is only used to explain the present invention and does not constitute a limitation on the present invention. The scope of the present invention is determined by the technical solutions defined in the claims.
