[0056] The present invention provides a folding styler 100, specifically, see Figure 1 , Figure 3 and Figure 9 As shown, in this embodiment, the folding shaper 100 includes a first barrel 1, a second barrel 2, and a pivot structure 3; the pivot structure 3 pivotally connects the first barrel 1 and the second barrel 2, so that the first barrel 1 and the second barrel 2 can rotate relative to each other, so as to have a folded state in which they are arranged in parallel, an extended state in which one end is opposite to the other end, and a bent state. In the bent state, the central axis of the first barrel 1 and the central axis of the second barrel 2 are arranged at an angle, and the angle is a minor angle or a major angle.

[0057] In this embodiment, the first cylinder 1 and the second cylinder 2 are connected by a pivoting structure 3, enabling relative rotation between the first cylinder 1 and the second cylinder 2. Thus, the included angle between the first cylinder 1 and the second cylinder 2 can be adjusted, allowing the first cylinder 1 and the second cylinder 2 to work at different included angle positions, making the working states of the folding shaper 100 more diverse. When the first cylinder 1 and the second cylinder 2 are in a parallel folding state, the volume of the folding shaper 100 is smaller and more convenient for storage. When the first cylinder 1 and the second cylinder 2 are in an extended state with one end facing each other and the other end facing away, the first cylinder 1 and the second cylinder 2 can be fully extended, providing a larger operating distance and better air outlet direction adjustment. When in a bent state, the central axis of the first cylinder 1 and the central axis of the second cylinder 2 are arranged at an included angle, and the included angle is an obtuse angle (greater than 0° and less than 180°) or a reflex angle (greater than 180° and less than 360°). The first cylinder 1 and the second cylinder 2 can work in an "L" shape or a "V" shape to meet the usage requirements of special usage environments. The adjustable range of the first cylinder 1 and the second cylinder 2 is larger, so it can better meet the various usage requirements of different users, is more convenient to use, and provides a better user experience.

[0058] Among them, the folding shaper 100 can be set as a hair dryer or a curling iron. One of the first cylinder 1 and the second cylinder 2 can be set as the air duct, and the other can be set as the handle part. It is assumed that the first cylinder 1 is set as the air duct and the second cylinder 2 is set as the handle part. An air outlet hole 11 is provided on the first cylinder 1. It can be understood that the air inlet hole 21 can be provided on the first cylinder 1, and / or the second cylinder 2, and / or the pivoting structure 3, so that after the air flow enters the first cylinder 1, it can be blown out from the air outlet hole 11 for the user to use.

[0059] It can be understood that the folding shaper 100 can also include a heating component and a circuit structure 4. The heating component is electrically connected through the circuit structure 4 to control the operation of the heating component. Among them, the heating component and the circuit structure 4 can be both arranged in the same cylinder, or can be respectively arranged in the first cylinder 1 and the second cylinder 2.

[0060] Preferably, the heating component is disposed within the first cylinder 1, the circuit structure 4 is disposed within the second cylinder 2, the air inlet hole 21 is provided on the second cylinder 2, and an air passage is provided on the pivoting structure 3. The air passage communicates the air inlet hole 21 and the air outlet hole 11, such that the first cylinder 1 and the second cylinder 2 are in communication. In the direction of the airflow, the circuit structure 4 is located within the communication passage between the air inlet hole 21 and the air passage. After the cold air flows into the second cylinder 2 from the air inlet hole 21, it can flow through the circuit structure 4 and then enter the first cylinder 1 through the air passage, and after being heated by the heating structure, it flows out of the first cylinder 1 from the air outlet hole 11. With such an arrangement, on the one hand, the cold air can flow through the circuit structure 4 to dissipate heat from the circuit structure 4, and on the other hand, the hot air around the circuit structure 4 can be brought into the first cylinder 1 to improve the heating efficiency and save more heating energy consumption.

[0061] By adjusting the relative angle between the first cylinder 1 and the second cylinder 2, the folding shaper 100 can be in different working states to meet different usage requirements of users. Preferably, the first cylinder 1 and the second cylinder 2 can rotate reciprocally between a folded state, a bent state, and an extended state in sequence, such that an included angle θ is formed between the central axis of the first cylinder 1 and the central axis of the second cylinder 2. Among them, when the bending angle is a concave angle, preferably the included angle θ is 0 to 180°; when the bending angle is a convex angle, preferably the included angle θ can be 0 to 360°. Among them, the adjustment of the included angle between the first cylinder 1 and the second cylinder 2 can be achieved by driving the first cylinder 1 and / or the second cylinder 2 to rotate through a driving mechanism, making the conversion of various working states of the folding shaper 100 more intelligent; or, the adjustment of the included angle between the first cylinder 1 and the second cylinder 2 can be manually adjusted, with a simpler structure and lower cost.

[0062] It can be understood that there are many ways to relatively rotatably connect the first cylinder 1 and the second cylinder 2. In one embodiment, the rotation plane of the first cylinder 1 (i.e., the plane through which the central axis of the first cylinder 1 rotates) and the rotation plane of the second cylinder 2 (i.e., the plane through which the central axis of the second cylinder 2 rotates) can be set to be non-coplanar. For example, the rotation plane of the first cylinder 1 and the rotation plane of the second cylinder 2 are arranged in parallel and / or intersecting, such that the first cylinder 1 and the second cylinder 2 are misaligned in the rotation direction, thereby better achieving large-angle rotation. And / or, one of the first cylinder 1 and the second cylinder 2 can rotate on its own axis. By the relative self-rotation of the first cylinder 1 and the second cylinder 2, the angle between the two can be changed.

[0063] Preferably, during the relative rotation of the first cylinder 1 and the second cylinder 2, the central axes of the first cylinder 1 and the second cylinder 2 are always in the same plane, and the support between the first cylinder 1 and the second cylinder 2 is always in a centered state during rotation. Therefore, when holding the second cylinder 2 and rotating the first cylinder 1, the first cylinder 1 will not tilt to one side, making the rotation of the first cylinder 1 easier and more labor-saving, and the user will also have a better hand feeling when using it. Moreover, it will not occupy too much space in the axial direction of the pivot structure 3, and the folding shaper 100 is more compact in volume.

[0064] Wherein, the first cylinder 1 and the second cylinder 2 have a folded state arranged in parallel. Here, parallel means that the central axes of the first cylinder 1 and the second cylinder 2 are substantially parallel, and most of the radial projections of the first cylinder 1 and the second cylinder 2 overlap. Therefore, when in the folded state, the overall length of the folding shaper 100 (i.e., along the axial direction of each cylinder) is shorter, and the space occupied during storage is smaller.

[0065] Preferably, the lengths of the first cylinder 1 and the second cylinder 2 along their respective axes are substantially the same. When in the folded state, the two ends of the first cylinder 1 and the second cylinder 2 are aligned, so the storage is more regular and more compact.

[0066] The shapes and sizes of the first cylinder 1 and the second cylinder 2 may not be specifically limited. For example, they may be square, polygonal or irregular, etc. Preferably, both the first cylinder 1 and the second cylinder 2 are cylindrical and have the same diameter, so that when the folding shaper 100 is in the folded state and the extended state, the outer shape structure is more symmetrical, more beautiful, and the holding comfort is also better.

[0067] Furthermore, in combination with Figure 1 and Figure 2 As shown, when in the folded state, the first side of the first cylinder 1 is parallel to and / or abuts against the first side of the second cylinder 2. Among them, the first cylinder 1 and the second cylinder 2 may partially abut or completely fit. And preferably, the included angle θ = 0°. So when in the folded state, there is almost no gap between the first cylinder 1 and the second cylinder 2, it is closer, so the volume is smaller and it is easier to store for convenient carrying.

[0068] Moreover, the first barrel 1 and the second barrel 2 also have an extended state with one end facing each other and the other end facing away from each other, so that one end of the first barrel 1 and one end of the second barrel 2 can be better connected, and the other end of the first barrel 1 and the other end of the second barrel 2 are far away from each other, and the angle between the central axis of the first barrel 1 and the central axis of the second barrel 2 is in an obtuse angle and close to a straight angle. Among them, the air outlet 11 can be set on the peripheral side wall of the first barrel 1 or at the end of the first barrel 1. When the air outlet is also set at the end of the first barrel 1, when the user holds the second barrel 2, the air outlet 11 of the first barrel 1 can be extended farther, so that the operable distance can be farther, and the user can operate more labor-saving.

[0069] Preferably, combined Figures 9 to 11 As shown, when in the extended state, the first cylinder 1 and the second cylinder 2 are coaxially arranged, and preferably the angle θ=180°. Specifically, the first cylinder 1 has a first end and a second end that are opposite to each other along its axial direction, and the second cylinder 2 also has a first end and a second end that are opposite to each other along its axial direction. When in the extended state, the first end of the first cylinder 1 and the first end of the second cylinder 2 are connected to each other, the second end of the first cylinder 1 is arranged in a direction facing away from the second cylinder 2, and the second end of the second cylinder 2 is arranged in a direction facing away from the first cylinder 1. The first end and the second end of the first cylinder 1, and the first end and the second end of the second cylinder 2 are all on the same straight line. At this time, the first cylinder 1 and the second cylinder 2 are fully extended, and the wind resistance on the airflow flow path is smaller, so the air outlet efficiency is also higher. It can be understood that when in the extended state, the angle θ is not completely limited, and the angle θ can be close to 180°, such as 180°±5°, so that the first cylinder 1 and the second cylinder 2 are roughly arranged in a straight line.

[0070] Of course, combined Figures 3 to 5 As shown, the first barrel 1 and the second barrel 2 also have a bending state between the folded state and the extended state, at which time the angle between the first barrel 1 and the second barrel 2 is greater than 0° and less than 180°. For example, the first barrel 1 and the second barrel 2 are in a "V" shape or an "L" shape, so that the folding styler 100 can be in a preset angle position for use in special environments.

[0071] In one embodiment, the folding shaper 100 may further include one or more positioning structures. Through the one or more positioning structures, the first cylinder 1 and the second cylinder 2 can be maintained in one or more of the above-mentioned states. When in the extended state or the bent state, the first cylinder 1 and the second cylinder 2 will not rotate randomly, so as to better maintain the working state. Among them, the specific form of the positioning structure is not specifically limited. The positioning structure can be set as a positioning protrusion to be clamped and matched with one or more grooves on the rotation path of the pivot structure 3, so as to position the pivot structure 3 at a preset rotation angle. Alternatively, when the first cylinder 1 and the second cylinder 2 are driven to rotate by a driving mechanism, the positioning structure can be set as a position sensor. By detecting the position sensor to control the operation of the driving mechanism, the first cylinder 1 and the second cylinder 2 can be controlled at different states, and the operation is more intelligent and convenient.

[0072] It is set that the first cylinder 1 and the second cylinder 2 rotate on a horizontal plane. Preferably, the pivot axis of the pivot structure 3 is arranged in the vertical direction. When in the extended state, the pivot axis of the pivot structure 3 is perpendicular to the central axis of the first cylinder 1 and / or the central axis of the second cylinder 2, so that the first cylinder 1 and the second cylinder 2 rotate more smoothly and are not prone to torsion or shaking.

[0073] Among them, when in the folded state, the first side of the first cylinder 1 and the first side of the second cylinder 2 are arranged relatively. Among them, the shape of the first side of the first cylinder 1 is adapted to the shape of the first side of the second cylinder 2, so that when the first cylinder 1 and the second cylinder 2 are in the folded state, the two can be closer to each other.

[0074] Moreover, in combination Figure 11 and Figure 12 As shown, when in the extended state, in the positive projection along the axial direction of the pivot structure 3, the projections of the first cylinder 1 and the projections of the second cylinder 2 are both on the same side of the projection of the plane where the pivot axis of the pivot structure 3 is located, that is, the first side of the first cylinder 1 and / or the first side of the second cylinder 2 are both on the plane where the pivot axis is located or both on the first side of the plane where the pivot axis is located.

[0075] When the diameters of the first cylinder 1 and the second cylinder 2 are the same, when in the extended state, the first cylinder 1 and the second cylinder 2 are coaxially arranged; the distance between the plane where the central axis of the first cylinder 1 is located and / or the plane where the central axis of the second cylinder 2 is located and the plane where the pivot axis of the pivot structure 3 is located is set as H, where the distance H is greater than or equal to 0 or less than or equal to the radius R of the first cylinder.

[0076] Among them, when the diameters of the first cylinder 1 and the second cylinder 2 are equal and in the extended state, the first side of the first cylinder 1 is flush with the first side of the second cylinder 2, and the pivot axis is exactly located on the plane where the first side of the first cylinder 1 and the first side of the second cylinder 2 are located. The distance H is equal to the radius R of the first cylinder 1. The first cylinder 1 and the second cylinder 2 can better achieve a rotation approaching 180° when rotating in the same plane. When the pivot axis of the pivot structure 3 is exactly located on the straight line where the first side edge of the first cylinder 1 and / or the second cylinder 2 is located, in the folded state, the first side of the first cylinder 1 and the first side of the second cylinder 2 are exactly in contact, and the first cylinder 1 and the second cylinder 2 are parallel and close to each other, maintaining the best folded state.

[0077] When the diameters of the first cylinder 1 and the second cylinder 2 are set inconsistently, or when the first cylinder 1 and the second cylinder 1 are arc-shaped or irregularly shaped, in combination with Figure 11 As shown, the plane where the pivot axis of the pivot structure 3 is located is set as plane S1. When one of the first cylinder 1 and the second cylinder 2 has a convex portion extending from the first side of plane S1 to the second side of plane S1, the other corresponding one is provided with a relief space located on the first side of plane S1, and the relief space is adapted to accommodate the convex portion. For example, when a button or a decorative piece protrudes from the first side of the first cylinder 1, a corresponding relief groove or a receiving area is provided on the first side of the second cylinder 2, so that in the folded state, the convex portion on the first cylinder 1 will not abut against the second cylinder 2, enabling the first cylinder 1 and the second cylinder 2 to be closer, and the folded storage volume to be smaller. Preferably, the shape of the relief space is adapted to the shape of the convex portion, that is, the shape of the part of the first cylinder 1 protruding from the second side of plane S1 matches the shape of the second cylinder 2 shrinking on the first side of plane S1. Thus, in the folded state, through the cooperation of the concave portion and the convex portion, the first cylinder 1 and the second cylinder 2 can be adapted to be close to each other, making the included angle between the first cylinder 1 and the second cylinder 2 approach or equal to 0°, and better folded and stored.

[0078] For the pivot structure 3, it is mainly used for rotatably connecting the first cylinder 1 and the second cylinder 2. Preferably, the pivot structure 3 is used to keep the first cylinder 1 and the second cylinder 2 rotating in the same plane, so that in the folded state, the two cylinders can be more closely attached, and thus the storage volume is smaller. In the extended state, the first cylinder 1 and the second cylinder 2 can better be kept on the same straight line, and the appearance is more smooth.

[0079] Preferably, in combination with Figures 6 to 8As shown, the pivoting structure 3 includes a shaft body portion 33, a first rotating portion 31, and a second rotating portion 32. The first rotating portion 31 is rotatably sleeved outside the shaft body portion 33 and connected to the first cylinder 1. The second rotating portion 32 is rotatably sleeved outside the shaft body portion 33 and connected to the second cylinder 2. Among them, the first rotating portion 31 and the second rotating portion 32 can rotate relative to each other, and the central axes of the first cylinder 1 and the second cylinder 2 are in the same plane. By connecting the shaft body portion 33 and the first cylinder 1 through the first rotating portion 31, and connecting the shaft body portion 33 and the second cylinder 2 through the second rotating portion 32, under the transitional action of the first rotating portion 31 and the second rotating portion 32, while the first cylinder 1 and the second cylinder 2 can rotate relative to each other, the central axes of the first cylinder 1 and the second cylinder 2 can better be in the same plane to ensure that the first cylinder 1 and the second cylinder 2 do not shift during the rotation process.

[0085] Furthermore, the shaft body part 33 connects the first sleeve body 3211 and the second sleeve body 3212, so that the first rotating sleeve 311 is rotationally clamped between the first sleeve body 3211 and the second sleeve body 3212, and there are a plurality of air passing holes 312 on the first rotating sleeve 311. The first sleeve body 3211 and the second sleeve body 3212 can be connected through the shaft body part 33, and the first sleeve body 3211 and the second sleeve body 3212 are respectively located at both axial ends of the first rotating sleeve 311, enabling the first rotating sleeve 311 to rotate relative to the shaft body part 33. When in the extended state, the plurality of air passing holes 312 can be in a blocked state, and the air flow directly enters the first cylinder body 1 from the second cylinder body 2 through the pivot structure 3; when in the bent state, at least part of the plurality of air passing holes 312 is in communication with the outside and can be used for air intake, so that a part of the air flow can directly enter the pivot structure 3 from the plurality of air passing holes 312 and then enter the first cylinder body 1, improving the air intake efficiency.

[0086] Specifically, in combination with Figures 6 to 8 As shown in the figure, the shaft body part 33 includes a locking shaft 331, a pressing sleeve 333 and an end cover 332. The locking shaft 331 passes through the second sleeve body 3212 and the first sleeve body 3211 from bottom to top and is locked to the end cover 332 to connect the first sleeve body 3211 and the second sleeve body 3212. The pressing sleeve 333 is sleeved outside the locking shaft 331 and presses at least part of the first rotating sleeve 311 onto the second sleeve body 3212, enabling the first rotating sleeve 311 to rotate relative to the second sleeve body 3212 and the pressing sleeve 333. The structure is simple and the assembly is convenient.

[0087] Among them, the first cylinder body 1 may include a first inner cylinder, a first outer cylinder, and an air outlet member provided at the front end of the first outer cylinder.
