Furthermore, the pivot centers of the first and second rotating parts are offset on the same side of the central axis of the first and second cylindrical bodies. In the extended state, the first and second rotating parts do not occupy axial space along the axial direction of the first and second cylindrical bodies, better ensuring a smaller axial dimension of the hair styling device in the extended state, making it easier for users to operate. Furthermore, by opening the first and second rotating parts at least partially on the periphery of their docking point, it facilitates the rotational connection between the first and second rotating parts. On the other hand, by covering the open areas of the first and second rotating parts with a shielding member, the connection between the first and second cylinders can be better sealed. Moreover, the overall wall thickness at the shielding member is smaller, resulting in a larger internal space at the connection between the first and second rotating parts. Consequently, the airflow path is smoother, leading to better airflow performance of the hair styling equipment. Attached Figure Description

[0022] This utility model provides a hair styling device 100. For details, please refer to... Figures 1 to 3 In this embodiment, the hair styling device 100 includes a first cylindrical body 1, a second cylindrical body 2, and a cover member 3. The first cylindrical body 1 includes a first cylindrical main body 11 and a first rotating part 12 protruding from one axial end of the first cylindrical main body 11. The second cylindrical body 2 includes a second cylindrical main body 21 and a second rotating part 22 protruding from one axial end of the second cylindrical main body 21; the first rotating part 12 and the second rotating part 22 are pivotally connected, such that the first cylindrical main body 11 and the second cylindrical main body 21 can rotate relative to each other to have an extended state and a bent state, and the peripheral side surface of the pivot docking point of the first rotating part 12 and the second rotating part 22 is at least partially open. The cover member 3 is detachably connected to the first rotating part 12 and / or the second rotating part 22 and covers the open parts of the first rotating part 12 and the second rotating part 22. In the extended state, the first cylindrical body 11 and the second cylindrical body 21 are arranged in a straight line, and the pivot centers of the first rotating part 12 and the second rotating part 22 are offset on the same side of the central axis of the first cylindrical body 11 and the central axis of the second cylindrical body 21, with the blocking member 3 located inside the first cylindrical body 11 and the second cylindrical body 21. In the bent state, the first rotating part 12 and the second rotating part 22 rotate relative to each other, causing the blocking member 3 to protrude from the first cylindrical body 11 and the second cylindrical body 21.

[0023] In this embodiment, the first cylindrical body 1 can be configured as a hair dryer, and the second cylindrical body 2 can be configured as a handle. The first cylindrical body 1 and the second cylindrical body 2 are rotatably connected by the first rotating part 12 and the second rotating part 22, allowing the first cylindrical body 1 and the second cylindrical body 2 to be used in a bent state and an extended state, providing more versatility in usage. Furthermore, the pivot centers of the first rotating part 12 and the second rotating part 22 are offset on the same side of the central axis of the first cylindrical body 1 and the central axis of the second cylindrical body 2. In the extended state, the first rotating part 12 and the second rotating part 22 do not occupy axial space along the axial direction of the first cylindrical body 1 and the second cylindrical body 2, better ensuring that the axial dimension of the hair styling device 100 is smaller in the extended state, making it easier for the user to operate. Furthermore, the first rotating part 12 and the second rotating part 22 are at least partially open on the periphery of their docking point. This facilitates the rotational connection between the first rotating part 12 and the second rotating part 22. On the other hand, the cover 3, which is placed over the open area of ​​the first rotating part 12 and the second rotating part 22, can better seal the connection between the first cylinder 1 and the second cylinder 2. Moreover, the overall wall thickness of the cover 3 is smaller, which makes the internal space of the first rotating part 12 and the second rotating part 22 larger. Therefore, the airflow path is smoother, resulting in better air output of the hair styling device 100.

[0024] Preferably, during the relative rotation of the first cylinder 1 and the second cylinder 2, the central axis of the first cylinder 1 and the central axis of the second cylinder 2 are always located on the same plane. During the rotation, the mutual support between the first cylinder 1 and the second cylinder 2 is always in a centered state. Therefore, when the first cylinder 1 is rotated while holding the second cylinder 2, the first cylinder 1 will not tilt to one side, making the first cylinder 1 easier and less strenuous to rotate, and providing a better feel for the user.

[0025] In one embodiment, the first cylindrical body 11 and the second cylindrical body 21 are approximately the same length along their respective axial directions.

[0026] In another embodiment, the axial length of the first cylinder body 11 is less than the axial length of the second cylinder body 21. Since the first cylinder body 1 is the air outlet, setting the length of the air outlet to be shorter will result in a shorter flow path for the hot airflow formed after the airflow is heated by the heating component, resulting in less heat loss and thus higher airflow efficiency.

[0027] The shape and size of the first cylindrical body 11 and the second cylindrical body 21 are not specifically limited, and can be square, polygonal, or irregular in shape. Preferably, the first cylindrical body 11 and the second cylindrical body 21 are both cylindrical and have the same diameter, so that the external structure of the hair styling device 100 is more symmetrical and aesthetically pleasing when the first cylindrical body 11 and the second cylindrical body 21 are in a bent state and an extended state, and the grip is also more comfortable.

[0028] Specifically, when rotating from the extended state to the bent state, the first side of the first cylinder body 11 and the first side of the second cylinder body 21 move toward each other. Preferably, the pivot axes of the first rotating part 12 and the second rotating part 22 are located exactly on the straight line of the first side of the first cylinder body 11 and / or the second cylinder body 21.

[0029] The first rotating part 12 and the second rotating part 22 are nested and connected, so that the first cylindrical body 11 and the second cylindrical body 21 can rotate better along the same plane. The distance between them along the axial direction of the first cylindrical body 11 or the second cylindrical body 21 is closer and the axial dimension is shorter. Along the radial direction of the first cylindrical body 11 or the second cylindrical body 21, they are on the same plane. The dimensions of the entire hair styling device 100 in all directions are smaller, so the volume can be smaller.

[0030] Specifically, in combination Figures 3 to 5 As shown, the first rotating part 12 includes a first rotating sleeve 121, a mounting base plate 122 disposed inside the first rotating sleeve 121, and a rotating column 123 disposed on the mounting base plate 122. The first rotating sleeve 121 is open at both ends, and its peripheral sidewalls are not fully circumferential, forming at least a first opening. During rotation, the first opening remains connected to both the first cylindrical body 11 and the second cylindrical body 21. Preferably, the first rotating sleeve 121, the mounting base plate 122, and the rotating column 123 are integrally formed.

[0031] The second rotating part 22 includes a second rotating sleeve 221 sleeved on the outside of the first rotating sleeve 121, and a first cover plate 222 and a second cover plate 223 disposed at both ends of the second rotating sleeve 221 along its axial direction. The first cover plate 222 and the second cover plate 223 are respectively rotatably connected to the rotating column 123. The second rotating sleeve 221 is also open at both ends, and the peripheral sidewall of the second rotating sleeve 221 is not a complete circle, so as to form at least a second opening. The first opening and the second opening are opposite to each other, and during the rotation of the second cylinder 2, the second opening is kept in communication with both the first cylinder body 11 and the second cylinder body 21.

[0032] The mounting base plate 122 is horizontally positioned inside the first rotating sleeve 121, with one side of the mounting base plate 122 facing the first cover plate 222 and the other side facing the second cover plate 223. Both the first cover plate 222 and the second cover plate 223 are detachably connected to the second rotating sleeve 221. The shielding member 3 covers the first and second openings and is connected to the rotating column 123, thereby better sealing the openings of the first rotating part 12 and the second rotating part 22, preventing external dust and other contaminants from entering the hair styling equipment 100.

[0033] Furthermore, such as Figure 3As shown, the second cylindrical body 21 includes a first half-cylinder 211 and a second half-cylinder 212 connected to each other, so as to facilitate the installation of circuit structures or other components within the second cylindrical body 21. The first half-cylinder 211 and the second half-cylinder 212 can be connected and fixed by screws and / or clips. Correspondingly, the second rotating sleeve 221 includes a first rotating half-sleeve 2211 and a second rotating half-sleeve 2212 that abut against each other. A first cover plate 222 and a second cover plate 223 are connected and respectively cover both ends of the first rotating sleeve 221 along its axial direction. The connection between the first cover plate 222 and the second cover plate 223 can be located on the side away from the second cylindrical body 21. The connection between the first cover plate 222 and the second cover plate 223 makes it less likely for gaps to form at the joint of the first rotating half-sleeve 2211 and the second rotating half-sleeve 2212, resulting in a tighter connection.

[0034] Specifically, a connecting post 2221 protrudes from the first cover plate 222, and a connecting hole is provided on the second cover plate 223 to connect and mate with the connecting post 2221. The first cover plate 222 and the second cover plate 223 are connected and fixed by screws or bolts passing through the connecting post 2221 and the connecting hole.

[0035] Since the first rotating sleeve 121 and the second rotating sleeve 221 will rotate relative to each other, further, combined Figure 3 and Figure 5 As shown, a through hole 1221 is provided on the mounting base plate 122. The connecting post 2221 can pass through the through hole 1221 and connect to the connecting hole. The through hole 1221 is arranged in an arc shape with the rotating post 123 as the center. During the rotation of the first rotating sleeve 121 and the second rotating sleeve 221, the connecting post 2221 can move along the through hole 1221. On the one hand, the through hole 1221 can avoid the connecting post 2221, and on the other hand, the through hole 1221 can limit the movement stroke of the connecting post 2221, thereby limiting the relative rotation angle of the first cylinder 1 and the second cylinder 2.

[0036] The mounting base 122 is equipped with a stop plate, and the first cover plate 222 or the second cover plate 223 is equipped with a telescopic contact. The stop plate has two or more stop slots. When the hair styling device 100 is in the extended state, the telescopic contact is engaged in one of the stop slots and emits a locking beep, indicating that it is properly engaged. At this time, the hair styling device 100 can maintain its extended state for operation. When the user rotates the first cylinder 1 and / or the second cylinder 2, the telescopic contact can be driven out of the stop slot and move along the stop plate. When the telescopic contact moves to the next stop slot, it emits another locking beep, indicating that it is properly engaged. At this time, the hair styling device 100 can maintain its bent state for operation. This allows the hair styling device 100 to better maintain both the extended and bent states for operation.

[0037] One of the aforementioned first cover plate 222 or second cover plate 223 can be configured as a display bracket. Specifically, the first cover plate 222 is configured as a display bracket. The hair styling device 100 may also include a display screen, which is mounted on the display bracket and sleeved on one axial end of the second rotating sleeve 221. The aforementioned connecting post 2221 can be mounted on the display bracket. This allows the display screen to better show the working status of the hair styling device 100. The display screen can be configured as a touch screen, displaying the working level, working temperature, and / or working mode of the hair styling device 100, etc. The working status of the hair styling device 100 can also be adjusted and switched through the display screen, making the operation of the hair styling device 100 more intelligent and effectively improving the user experience.

[0038] For shielding component 3, such as Figure 3 As shown, the shielding member 3 is configured as a shielding cover 31. The shielding cover 31 has a shielding wall 311 arranged in an arc shape. The two ends of the shielding wall 311 extend into the first cylindrical body 11 and the second cylindrical body 2 respectively along its circumference. The first cylindrical body 1 and the second cylindrical body 2 can rotate relative to the shielding cover 31. This ensures that the shielding wall 311 and the first cylindrical body 11 and the second cylindrical body 21 maintain at least partial overlap, making it less likely to generate gaps and ensuring a better shielding effect.

[0039] Preferably, the central angle of the arc surface where the shielding wall 311 is located is greater than the relative rotation angle of the first cylindrical body 11 and the second cylindrical body 21. This ensures that the shielding wall 311 can always provide shielding during the rotation of the first cylindrical body 11 and the second cylindrical body 21.

[0040] Furthermore, the arc surface of the shielding wall 311 is concentrically arranged with the first rotating sleeve 121 and the second rotating sleeve 221. The shielding cover 31 also has a first connecting portion 312 and a second connecting portion 313 extending radially along the shielding wall 311 and spaced apart along the axial direction of the shielding wall 311. Both the first connecting portion 312 and the second connecting portion 313 are sleeved on the rotating column 123. The first connecting portion 312 connects between the first cover plate 222 and the mounting base plate 122, and the second connecting portion 313 connects between the second cover plate 223 and the mounting base plate 122. The first connecting portion 312 and the second connecting portion 313 allow the shielding cover 31 to be better installed at the first rotating portion 12 and the second rotating portion 22, and allow both the first rotating portion 12 and the second rotating portion 22 to rotate relative to the shielding cover 31.

[0041] The first connecting part 312 and the second connecting part 313 are both provided with mating holes at their ends, which are fitted onto the outer side of the rotating column 123. The inner circumference of each mating hole has multiple protrusions, which are spaced apart circumferentially along the hole to abut against the outer side of the rotating column 123. This ensures a point-to-surface fit between the first connecting part 312 and the rotating column 123, and between the second connecting part 313 and the rotating column 123. Therefore, when the first cylinder 1 and the second cylinder 2 rotate, the shielding cover 31 will not rotate, better ensuring the position of the shielding cover 31 and making rotation of the first cylinder body 11 and the second cylinder body 21 easier.

[0042] Furthermore, the hair styling device 100 also includes a first limiting part and a second limiting part arranged at intervals along the circumference of the rotating column 123. When switching from a bent state to an extended state, the first cylinder 1 rotates relative to the blocking member 3 in a first direction, and the second cylinder 2 rotates relative to the blocking member 3 in a second direction. In the extended state, the first limiting part abuts against the first end of the blocking member 3 in the circumferential direction to limit the first cylinder 1 from continuously rotating in the first direction, and the second limiting part abuts against the second end of the blocking member 3 in the circumferential direction to limit the second cylinder 2 from continuously rotating in the second direction.

[0043] Moreover, combined Figures 4 to 7 As shown, the hair styling equipment 100 also includes a fan assembly 5 and an air venting sleeve 6. The fan assembly 5 includes a fan bracket 51 and a fan body 52 disposed within the fan bracket 51. The air venting sleeve 6 is fitted onto the air inlet end of the fan bracket 51. (Combined with...) Figure 10 As shown, the air venting sleeve 6 has a sleeve body fitted onto the outside of the fan bracket 51, multiple air vents located on the inside of the sleeve body, and a limiting protrusion 441 protruding from the outside of the sleeve body. The limiting protrusion 441 extends radially outward from the outer peripheral sidewall of the sleeve body. A limiting rib 314 protrudes from the inside of the shielding member. The limiting protrusion 441 forms the fourth limiting part 44. When in a bent state, the limiting protrusion 441 and the limiting rib 314 engage to prevent the second cylinder 2 from continuing to rotate in the bending direction, thereby keeping the second cylinder 2 in a bent state for operation.

[0044] The air outlet end of the fan bracket 51 is fixed inside the first cylindrical body 11 and conforms to the inner side wall of the first cylindrical body 11. The air inlet end of the fan bracket 51 is fixed to the first rotating part 12. The bend transition between the air inlet end and the air outlet end of the fan bracket 51 forms a first limiting part 35. In the extended state, one end of the blocking member 3 abuts against the outer side of the fan bracket 51, and the other end of the blocking member 3 abuts against the connection transition between the second cylindrical body 21 and the second rotating part 22, thereby keeping the hair styling equipment in the extended state for operation. Figure 8 and Figure 9As shown, the third limiting part 43 includes a first boss 431 protruding from the inner side of the second cover plate and a second boss 432 protruding from the display bracket. When in a bent state, one side of the first connecting part 312 and one side of the second connecting part 313 of the blocking member abut against the first boss 431 and the second boss 432 respectively, so as to restrict the first cylinder 1 from continuing to rotate in the bending direction, thereby keeping the first cylinder 1 and the second cylinder 2 in a bent working state.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
