Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The core of the present utility model is to provide a hair curler for a hair curler that increases the styling capability of the hair curler.

The core of the present utility model is to provide a hair curler for a hair curler that increases the styling capability of the hair curler.

The hair curler provided by the utility model is applied to the hair curler. As shown in fig. 1, the hair curler includes a handle portion 5 and a hair curling portion connected to the handle portion 5, and hair styling are achieved by heating hair through the hair curling portion to curl hair.

In a first embodiment, referring to fig. 2 to 11, the hair curling portion includes a heat conduction assembly 1, a fixing portion 2, and a rotating portion 3.

As shown in fig. 2 to 4, the heat conducting assembly 1 includes at least two heat conducting members 11 sequentially arranged around a preset center line, and three heat conducting members 11 are specifically provided, and in other embodiments, two, four or other numbers of heat conducting members 11 may be provided, so that the heat conducting assembly 1 forms a cylinder structure.

In the present utility model, unless otherwise specified, the axial direction, the circumferential direction, and the radial direction are based on a predetermined center line, and the predetermined center line extends in the axial direction, and is generally collinear with the center line of the hair curling portion.

One end of the heat conductive member 11 is radially movably connected to the fixed portion 2, and the other end is radially movably connected to the fixed portion 2. The rotating part 3 is rotatably connected to the fixed part 2, and the heat conducting member 11 is slidably connected to the rotating part 3. The heat conductive member 11 generally extends in the axial direction, and both ends of the heat conductive member 11 are both ends thereof in the axial direction unless otherwise specified.

When the heat conducting member is used, the fixed part 2 is kept still, the rotating part 3 rotates relative to the fixed part 2, wherein the fixed part 2 restrains the moving direction of the heat conducting member 11, so that each point on the heat conducting member 11 moving radially moves, and the rotating part 3 plays a role in adjusting the radial movement distance of the heat conducting member 11, and the radial movement of different positions on the heat conducting member 11 correspondingly moves by rotation.

During the rotation of the rotating portion 3, at least one angle, the two ends of the exposed side surface of the heat conducting member 11 are spaced from the preset center line at the same distance, so that the heat conducting component 1 is a cylinder. In the process of rotating the rotating part 3, the motion tracks of the two ends of the heat conducting piece 11 relative to the rotating part 3 are different, so that the exposed side surface of the heat conducting component 1 can be switched between a cylindrical surface and a conical surface. When the exposed side surface of the heat conduction assembly 1 is a cylindrical surface, the shape of the cylinder structure is regarded as a cylinder, and when the exposed side surface of the heat conduction assembly 1 is a conical surface, the shape of the cylinder structure is regarded as a cone.

It should be noted that, the exposed side of the heat conducting member 11 refers to the exposed surface that is directly in contact with hair after the heat conducting member 11 is assembled to the hair curler, and reference is made to the region D in fig. 2, in which 1, two ends of the exposed side of the heat conducting member 11 are two ends D1 and D2 in the axial direction. Likewise, the entire surface surrounded by the exposed sides of all the heat conductive members 11 is the exposed side of the heat conductive member 1, referring to the region E in the axial direction in fig. 1.

In this embodiment, under at least one angle, the distances between the two ends of the exposed side surface of the heat conducting member 11 and the preset center line are the same, so that a cylindrical surface state of the exposed side surface of the heat conducting component 1 can be ensured, when the rotating part 3 rotates, the fixing part 2 constrains the heat conducting member 11 to move radially but not circumferentially, and as the movement tracks of the two ends of the heat conducting member 11 relative to the rotating part 3 are different, the radial movement distances of the two ends of the heat conducting member 11 are not always the same in the process that the exposed side surface of the heat conducting component 1 rotates from the corresponding angle of the cylindrical surface to other angles, the cylindrical surface can be switched to a conical surface, so that the shape of the cylinder structure can be switched between the cylinder structure and the conical structure, and the modeling capability of the hair curler can be increased.

Further, referring to fig. 5 to 11, two ends of the heat conducting member 11 are respectively connected to the fixing portion 2 in a radially movable manner, and two ends of the heat conducting member 11 are respectively slidably connected to the rotating portion 3. When the fixed portion 2 is used as a stationary reference frame and the rotating portion 3 rotates, the heat conducting member 11 moves radially, and the heat conducting member 11 remains stationary in the circumferential direction, which requires that the connection position between the rotating portion 3 and the heat conducting member 11 is structurally provided with a guiding structure extending obliquely in the circumferential direction, and the heat conducting member 11 is slidingly connected to the guiding structure, so that during the rotation of the rotating portion 3, two ends of the heat conducting member 11 are respectively constrained to move on the rotating portion 3 along different movement tracks. The guide structure extends obliquely along the circumferential direction, and means that all positions of the guide structure in the circumferential direction are not completely equidistant from a preset central line.

Preferably, in the present embodiment, referring to fig. 2, the rotating part 3 includes a rotating rod 31 rotatably connected to the fixed part 2 and two rotating plates 32 fixed to the rotating rod 31, and both ends of the heat conducting member 11 are slidably connected to the track grooves 321 on the two rotating plates 32, respectively, as shown in fig. 9, the track grooves 321 connected to both ends of the same heat conducting member 11 are a and B, respectively. During the rotation of the rotating part 3, the movement track of the two ends of the heat conducting member 11 at the rotating part 3 is respectively restrained by the two track grooves 321. At this time, the track groove 321 is a guiding structure, which is convenient for processing, and correspondingly, the track groove 321 provided on the rotating plate 32 extends obliquely relative to the circumferential direction, so that the distances between each part of the track groove 321 relative to the preset center line are not identical, including completely different or partially different situations. The preset center line is also the rotation center line of the rotation piece 32. Specifically, the track groove 321 is an axial through groove.

As shown in fig. 2, the fixed part 2 includes a mount 21, and the rotating part 3 is rotatably connected to the mount 21. The mounting seat 21 is provided with radial grooves 211 extending along the radial direction, and the radial grooves 211 can provide at least two limiting points. At this time, the two ends of the heat conducting member 11 are respectively slidably connected to the radial slot 211 and the track slot 321, so as to rotate through the rotating portion 3, drive the heat conducting member 11 to move radially along the radial slot 211, and position the heat conducting member 11 in the radial direction, so as to switch the limiting point where the heat conducting member 11 stays on the radial slot 211, adjust the interval and the included angle between the heat conducting member 11 and the rotation center line of the rotating plate 32, and enable the shape of the cylinder structure to be switched between the cylinder structure and the cone structure.

Of course, in other embodiments, the track groove 321 in this embodiment may be replaced with a groove that is axially non-penetrating; alternatively, the heat conducting member 11 may be replaced by a protrusion structure, and a sliding groove may be provided on the heat conducting member to be slidably engaged with the protrusion structure.

Further, referring to fig. 8, 9 and 11, the movement tracks of both ends of the heat conductive member 11 on the rotating part 3 are the same in the first angular range in which the rotating part 3 rotates. Accordingly, as shown in fig. 8 and 9, when the rotating part 3 moves within the angular range, the connection point of one end of the heat conducting member 11 on the track groove a is located between the point a0 and the point a1, the connection point of the other end of the heat conducting member 11 on the track groove B is located between the point B0 and the point B1, the guide track between the point a0 and the point a1, and the guide track between the point B0 and the point B1 can be overlapped after translation in space, and the movement tracks of the two ends of the heat conducting member 11 restrained by the two are the same relative to the moving track of the rotating part 3. In this angular range, when the rotating part 3 moves from one angle to another, the distance of radial movement of both ends of the heat conducting member 11 is the same, and the whole heat conducting member 11 is translated in the radial direction, so that the cylindrical structure is changed without changing its shape.

Specifically, in this embodiment, in this first angular range, the exposed side of the heat conduction assembly 1 is kept cylindrical, that is, the diameter thereof is changed, and the axial section of the barrel structure can be changed from S1 to S2 as shown in fig. 11, which also improves the applicability of the hair curling portion. Of course, in other embodiments, the exposed side of the thermally conductive assembly 1 may also remain tapered within this angular range.

Further, as shown in fig. 9 to 11, in the movement locus of the both ends of the heat conductive member 11 on the rotating portion 3 in the second angle range in which the rotating portion 3 rotates, the interval between one movement locus and the preset center line in the circumferential direction becomes gradually smaller, and the interval between the other movement locus and the preset center line in the circumferential direction becomes gradually larger. Accordingly, as shown in fig. 9 and 10, when the rotating part 3 moves within the angular range, the connection point of one end of the heat conducting member 11 on the track groove a is located between the point a1 and the point a2, the connection point of the other end of the heat conducting member 11 on the track groove B is located between the point B1 and the point B2, the guide track between the point a1 and the point a2, and the guide track between the point B1 and the point B2 can be translated in space without overlapping, and thus, the movement tracks of the two ends of the heat conducting member 11 constrained by the two relative to the rotating part 3 are different. In this angular range, when the rotating part 3 moves from one angle to another, the distance of radial movement of both ends of the heat conductive member 11 may be different, for example, the distance of movement of one end becomes smaller and the distance of movement of the other end becomes larger, the entire heat conductive member 11 swings with respect to the preset center line, the cylindrical structure may change from a cylindrical body to a conical body after the rotating part 3 moves from the first angular range to the second angular range, the axial section of the cylindrical structure is substantially changed from S2 to S3 in fig. 11, and the taper degree is variable.

Of course, in other embodiments, a section with the same structure as that between the a0 point and the a1 point may be added on the side of the track groove a, away from the a1 point, and a section with the same structure as that between the B0 point and the B1 point may be added on the side of the track groove B, away from the B1 point, so that the cylinder structure may be changed from the cone to the cylinder again.

Further, as shown in fig. 2 and 3, the two ends of the heat conducting member 11 are respectively provided with a first connecting post 6 slidably connected with the two track grooves 321, and the two first connecting posts 6 are arranged in a collinear manner, and the radial distance between the exposed side surface of the heat conducting member 11 and the two first connecting posts 6 is the same. That is, at this time, the heat conducting member 11 may have a regular structure, and when the distances between the two track grooves 321 and the preset center line are the same, the distances between the exposed side surface of the heat conducting member 11 and the preset center line are also the same, so that the processing and the arrangement of the extending direction of the track grooves 321 are facilitated. Alternatively, in the present embodiment, the radial distance between the exposed side surface of the heat conductive member 11 and the two first connection posts 6 may be different. Alternatively, as shown in fig. 16, the two ends of the heat conducting member 11 are respectively provided with the second connecting posts 7 slidably connected with the two track grooves 321, and the two second connecting posts 7 are arranged in parallel, and the radial distances between the exposed side surface of the heat conducting member 11 and the two second connecting posts 7 are different, and at this time, the distance between the rotating grooves at the two ends of the heat conducting member 11 and the preset center line and the distance between the exposed side surface of the heat conducting member 11 and the second connecting posts 7 need to be combined to realize the formation of the column.

Further, as shown in fig. 10, in the two rotating plates 32, the axial projection of the outer peripheral surface of one rotating plate 32 is located inside the outer peripheral surface of the other rotating plate 32, and since the distance between each point on the two track grooves a and B and the preset center line varies, the maximum value of the distance between the points and the preset center line may also be different, and the size of the two rotating plates 32 is adaptively set according to the maximum value, which is beneficial to saving materials and cost. Of course, in other embodiments, the axial projection of the outer peripheral surface of one rotary plate 32 may also coincide with the outer peripheral surface of the other rotary plate 32.

Further, as shown in fig. 2, the track groove 321 has an arc-shaped structure, so that the heat conductive member 11 moves smoothly. In other embodiments, the track groove 321 may be a linear structure or a V-shaped structure with sharp turns.

Further, referring to fig. 5 and 6, on the same rotating piece 32, the track grooves 321 are uniformly arranged along the circumferential direction and have the same structure, and the same structure herein means that the track grooves 321 rotate around the rotation center line of the rotating piece 32 and can be overlapped with the same virtual setting area. Based on the setting, the radial movement distance of each heat conducting piece 11 is consistent under the drive of the rotating piece 32, and the shape of the cylinder structure is regular.

More specifically, as shown in fig. 4, the rotary piece 32 is fixedly connected to the rotary cap 4, the rotary cap 4 is sleeved outside the mounting seat 21, and the rotary piece 32 and the rotary rod 31 are driven to rotate by rotating the rotary cap 4.

Further, the exposed side surface of each heat conductive member 11 is an arc surface, and accordingly, a cylindrical barrel if a cylindrical structure is formed, and a truncated cone or a cone if a cone structure is formed. In other embodiments, the heat conducting member 11 may be substantially flat, and the cone structure formed by the heat conducting assembly 1 may be a square cone structure. In the cone structure, the end connected to the handle portion 5 may be a large diameter end or a small diameter end. In addition, a gap may be provided between the adjacent heat conductive members 11, and a closed structure may be maintained all the time by adjusting the overlapping area.

In the curling portion of this embodiment, the radial groove 211 restrains the heat conducting member 11 from moving in the radial direction but does not move in the circumferential direction, and since the track groove 321 on the rotating piece 32 extends obliquely with respect to the circumferential direction, the distance between each of the track grooves 321 with respect to the rotation center line of the rotating piece 32 is not exactly the same, so that the track groove 321 can push the heat conducting member 11 in the radial direction while the rotating piece 32 moves circumferentially with respect to the heat conducting member 11, the distance or angle between the heat conducting member 11 and the rotation center line of the rotating piece 32 can be adjusted, the shape or size of the barrel structure can be adjusted, and the shape of the barrel structure can be switched between the cylinder structure and the cone structure, so that the modeling capability of the curling iron can be increased.

In the second embodiment, the movement track of the two ends of the heat conducting member 11 with respect to the rotating portion 3 may be otherwise set, and referring to fig. 12 and 13, one of the rotating pieces 32 rotating piece 32A is kept the same as the first embodiment, and the other rotating piece 32 is replaced with the other rotating piece 32: the track groove 321 of the rotating plate 32 is spaced apart from the predetermined center line by a distance that is continuously small in one direction in the circumferential direction, clockwise or counterclockwise. In this embodiment, the cylinder structure may be a cylindrical structure only at one rotation angle of the rotary plate 32, and be a conical structure all the time at other rotation angles, and the taper may be continuously changed during the rotation of the rotary plate 32.

In the third embodiment, the heat conducting member 11 may be connected to the rotating portion 3 and the fixed portion 2 in another manner. As shown in fig. 14 and 15, the first end of the heat conducting member 11 is rotatably connected to the fixed portion 2, specifically connected to the fixed seat 22 of the fixed portion 2, the second end is radially movably connected to the fixed portion 2 and slidably connected to the rotating portion 3, and during the rotation of the rotating portion 3, the distance between each position of the movement track of the second end of the heat conducting member 11 on the rotating portion 3 in the circumferential direction and the preset center line is not exactly the same, specifically becomes gradually smaller. At this time, when the rotating portion 3 rotates, the heat conducting member 11 swings relative to the first end and the preset center line thereof, so as to adjust the included angle between the heat conducting member 11 and the preset center line, and at this time, the cylinder structure may be a cylindrical structure only under one rotation angle of the rotating portion 3, and be a cone structure all the time under other rotation angles.

According to the hair curling part provided by the utility model, the fixing part 2 provides at least two radial limiting points, the heat conducting piece 11 can be pushed to move at different limiting points in the rotating process of the rotating part 3, the dimensional change and/or the morphological change of the barrel structure can be realized, the barrel structure can be switched under the multi-element combination of the barrel and the cone or even the cross combination and other forms, and the rich diversity of modeling is realized.
