[0037] Existing hair dryers have a fixed airflow angle, which cannot meet the needs of various scenarios. While some hair dryers have variable airflow heads, they have certain drawbacks. For example, when the airflow head rotates relative to the body, it damages the overall appearance of the product, increases its overall size, and causes internal wiring to rotate back and forth, affecting its lifespan. It also easily leads to friction between the airflow head and the body, shortening its lifespan and causing a poor feel. Furthermore, the change in airflow duct shape after rotation increases noise and reduces airflow volume and speed. The airflow effect varies significantly at different airflow angles, resulting in unstable product performance.

[0038] Please refer to the reference. Figures 1 to 6 To address the aforementioned problems, this utility model proposes a hair dryer. According to an embodiment of this utility model, the hair dryer includes a handle 11, a movable part 13, and a heating element 124. The handle 11 has a fixed part 12; the movable part 13 is rotatably connected to the fixed part 12, and the movable part 13 and the fixed part 12 form a spherical structure. The movable part 13 is provided with an air outlet 131. The movable part 13 rotates relative to the fixed part 12 to change the orientation of the air outlet 131, and the movable part 13 and the fixed part 12 always maintain the spherical structure. It should be noted that the spherical structure here does not refer to a perfect sphere, such as... Figure 1 As shown, it can also be a spherical structure, for example, a flat end face is cut out on the surface of a sphere to serve as an air outlet.

[0039] According to this embodiment of the hair dryer, the fixed part 12 is connected to the handle 11, allowing the user to grip the handle 11 to use the hair dryer. The movable part 13 can rotate relative to the fixed part 12, thereby adjusting the blowing angle for user convenience. Simultaneously, the fixed part 12 and the movable part 13 combine to form a spherical structure, and both maintain this spherical structure when the movable part 13 rotates, preserving the product's shape. This prevents internal wiring from becoming entangled due to significant changes in product shape, reducing wiring difficulty and effectively improving product performance stability. By designing a spherical rotating air outlet structure, it meets various scenario requirements, maintains a relatively unchanged product shape, consistently minimizes noise and wind resistance, exhibits minimal performance differences, and demonstrates high reliability of the rotating structure.

[0040] More specifically, when the movable part 13 rotates relative to the fixed part 12, the interior of the spherical structure formed by the fixed part 12 and the movable part 13 maintains a generally spherical spatial shape. When airflow enters the interior of the spherical structure from the air inlet, it flows along the inner wall of the spherical structure to the air outlet. Thus, even when the air outlet angle is adjusted, the duct shape remains smooth and does not exhibit sharp bends; moreover, the duct shape changes little before and after the air outlet angle changes. Compared to related technologies where the duct shape undergoes sharp bends and significant changes when the air outlet angle is changed, the spherical structure formed by the fixed part 12 and the movable part 13 in this embodiment significantly improves product noise reduction and stabilizes airflow.

[0041] Please refer to the reference. Figure 1 and Figure 7 According to one embodiment of the present invention, both the fixed part 12 and the movable part 13 are hemispherical structures. Exemplarily, the spherical radius of the fixed part 12 and the spherical radius of the movable part 13 are the same. Both the fixed part 12 and the movable part 13 have an end face and a spherical surface. The end face of the fixed part 12 and the end face of the movable part 13 are connected, and the movable part 13 can rotate on the end face of the fixed part 12. In this case, the air outlet 131 is located on the spherical surface of the movable part 13, and the air outlet 131 is positioned close to the edge of the movable part 13. Thus, when the movable part 13 rotates, the orientation of the air outlet 131 changes accordingly. In another embodiment, the spherical radius of the fixed part 12 is larger than the spherical radius of the movable part 13. In this case, the movable part 13 can be embedded within the outer shell of the fixed part 12, and when the movable part 13 rotates, it can partially overlap with the fixed part 12. In other embodiments, the movable part 13 and the fixed part 12 may not be hemispherical structures, but rather spherical cap shapes; this is not limited here.

[0042] In this embodiment, the handle 11 can be elongated cylindrical for easy gripping by the user. The fixing part 12 can be embedded in the handle 11, or connected to the handle 11 by means of snaps, threads, etc. The fixing part 12 can also be integrally formed with the handle 11, which is not limited here. It is understood that at least a portion of the fixing part 12 is used to cooperate with the movable part 13 to form a spherical structure, and the remaining portion can be used to connect and fix with the handle 11. Of course, the fixing part 12 and the movable part 13 can also be combined to form a spherical structure, and then the fixing part 12 can be connected to the handle 11. It is understood that the hair dryer has an air inlet, which can be located on the handle 11 or the fixing part 12. Of course, air inlets can also be provided on both the handle 11 and the fixing part 12 to improve air intake efficiency. Taking the handle 11 with an air inlet as an example, the air inlet is located at the end of the handle 11 furthest from the movable part 13, avoiding the air inlet being too close to the air outlet 131. This allows the heating element 124 to be installed between the air inlet and the air outlet 131, so that the incoming air can pass through the heating element 124 before being discharged from the air outlet 131, enabling the hair dryer to blow hot air. In this way, the air inlet can be connected to the air outlet 131 of the movable part 13 through the hollow structure of the handle 11.

[0043] like Figure 7 As shown, in one embodiment, an air inlet mesh 16 covers the air inlet to prevent other debris from entering. Simultaneously, the air inlet is positioned around the handle 11, meaning that the air inlet is located on the curved surface of the handle 11. Compared to an air inlet located on a flat surface, the air inlet is less likely to be completely blocked. Thus, even if one side of the air inlet is obstructed, the other side can still function as an air intake point, resulting in better air intake performance.

[0044] According to one embodiment of this utility model, the hair dryer includes a heating element 124, which is disposed in the handle 11 or in the fixing part 12. Alternatively, the heating element 124 may be partially disposed in the handle 11 and partially in the fixing part 12; this is not limited here. It is understood that since the movable part 13 needs to rotate, its structure is complex, and the power cord routing is complicated, making it prone to failure. Therefore, by placing the heating element 124 in the handle 11 or the fixing part 12, the wiring will not move with the movable part 13, thereby avoiding wiring wear and extending the service life of the wiring. In some embodiments, components such as the motor 125, circuit board 126, and ion generator 123 are installed inside the fixing part 12 or the handle 11, resulting in simple internal wiring, a simple structure, and high reliability.

[0045] According to one embodiment of the present invention, the axis of rotation of the movable part 13 relative to the fixed part 12 is set at an angle to the axis of the handle 11. That is, the axis of rotation of the movable part 13 about the fixed part 12 is not coaxial with the axis of the handle 11. In this way, when the movable part 13 rotates, it is convenient to adjust the orientation of the air outlet 131. For example, when the handle 11 is cylindrical and extends vertically, its axis is also vertical. In this case, the movable part 13 rotates, and its axis of rotation forms an angle with the axis of the handle 11, for example, an acute angle. That is, the movable part 13 is tilted so that when the user grips the handle 11 in a vertical position, the movable part 13 can face the user, making it easier for the user to use the hair dryer and improving the user's feel.

[0046] According to one embodiment of the present invention, the angle between the rotation axis of the movable part 13 about the fixed part 12 and the axis of the handle 11 is 45°. It is understood that the side of the fixed part 12 facing the movable part 13 is an inclined mounting end face, and the movable part 13 is rotatably mounted on this mounting end face. When the handle 11 is in a vertical state, the mounting end face is inclined at 45°. Thus, when the movable part 13 rotates on this mounting end face, and the user grasps the handle 11, the mounting end face can face diagonally upwards to better face the user's head, allowing the movable part 13 to face the user, so that the user does not need to raise the hair dryer to blow air onto their head.

[0047] It should be noted that the movable part 13 can rotate 360° on the fixed part 12 to adjust the orientation of the air outlet 131, meeting the needs of multi-angle air outlet, and can flexibly cope with different usage scenarios and needs, improving the convenience and comfort of use. For example, the movable part 13 can rotate relative to the fixed part 12 to make the air outlet 131 outlet air horizontally, tilted, or vertically.

[0048] Please refer to the reference. Figure 3 and Figure 4According to one embodiment of the present invention, the hair dryer includes a locking structure 14. The locking structure 14 may be provided on the fixed part 12, or on the movable part 13, or between the fixed part 12 and the movable part 13. No limitation is made here. The locking structure 14 is used to fix the rotation angle of the movable part 13 relative to the fixed part 12.

[0049] Understandably, the locking structure 14 ensures that the air outlet 131 can be precisely fixed at the required angle, preventing displacement or shaking during use. The locking structure 14 can be a pin, a latch, a magnet, or any other structure that can maintain a fixed angle between the movable part 13 and the fixed part 12. For example, if the locking structure 14 is a magnet, magnets are provided at corresponding positions on the fixed part 12 and the movable part 13. The two magnets attract each other. When the movable part 13 rotates to a specific angle, such as when the air outlet 131 is horizontally discharging air, the two magnets magnetically engage, thereby fixing the rotation angle of the movable part 13 relative to the fixed part 12. When the locking structure 14 is a pin, when the movable part 13 rotates to a specific angle, the pin can engage between the fixed part 12 and the movable part 13, preventing the movable part 13 from rotating. Similarly, when the locking structure 14 is a latch, the latch can engage the fixed part 12 and the movable part 13, preventing the movable part 13 from rotating. It should be noted that when the movable part 13 needs to be rotated again, the user can grasp the pin to pull it out or pry open the latch to unlock the fixed part 12 and the movable part 13. Of course, the locking structure 14 can also be in other forms, which are not limited here.

[0050] According to one embodiment of the present invention, the locking structure 14 includes a latching protrusion 141 and a latching groove 142. The latching protrusion 141 is movably disposed on the fixed part 12, and the latching groove 142 is disposed on the movable part 13. The latching protrusion 141 is movable relative to the fixed part 12 to latch into or retract from the latching groove 142.

[0051] Understandably, the protrusion 141 may be partially exposed on the outer surface of the fixing part 12 to facilitate gripping and engaging it in or disengaging from the slot 142. For example, the locking structure 14 also includes a locking push button 143 connected to the protrusion 141, and an operating hole is provided on the outer surface of the fixing part 12. The locking push button 143 passes through the operating hole. When the user pushes the locking push button 143, the protrusion 141 moves accordingly to engage in or disengage from the slot 142, thus facilitating the user to lock or unlock the movable part 13. In this embodiment, the latching protrusion 141 has an arc-shaped structure to fit the arc surface of the spherical fixing part 12 for installation. The latching protrusion 141 can slide along the fixing part 12. The movable part 13 has a corresponding slot 142 on the side facing the fixing part 12. When the latching protrusion 141 slides along the fixing part 12 toward the movable part 13, and the movable part 13 rotates to the position of the slot 142 corresponding to the latching protrusion 141, the latching protrusion 141 can be inserted into the slot 142, completing the latching and fixing of the movable part 13 and the fixing part 12. For example, when the movable part 13 rotates to the horizontal air outlet position, the slot 142 and the latching protrusion 141 are aligned, and the user can latch the latching protrusion 141 into the slot 142 using the locking push button 143. This ensures that the air outlet 131 can be accurately fixed at the required angle, avoiding displacement or shaking during use.

[0052] According to one embodiment of the present invention, the locking structure 14 includes an elastic member 144. One end of the elastic member 144 is connected to the end of the latching protrusion 141 that is away from the latching groove 142, and the other end of the elastic member 144 is connected to the fixing part 12. The elastic member 144 is used to support the latching protrusion 141 to be latched in the latching groove 142.

[0053] Understandably, when the latching protrusion 141 aligns with the latching groove 142, the elastic element 144 expands to push the latching protrusion 141 towards the latching groove 142, thereby engaging the latching protrusion 141 within the latching groove 142, preventing loosening and improving engagement stability. When unlocking is required, the user can push the latching protrusion 141 to compress the elastic element 144, causing the latching protrusion 141 to disengage from the latching groove 142. At this point, rotating the movable part 13 will move the latching groove 142 away from the latching protrusion 141. Furthermore, when the movable part 13 rotates again to the position where the latching groove 142 corresponds to the latching protrusion 141, the elastic force of the elastic element 144 will automatically engage the latching protrusion 141 within the latching groove 142, locking the position of the movable part 13 for convenient operation. The elastic element 144 can be a spring, a sheet, a rubber post, etc., and is not limited here.

[0054] like Figure 1 , Figure 5 and Figure 6As shown, according to one embodiment of the present invention, the movable part 13 is provided with a plurality of slots 142 at intervals. It is understood that, in order to enable the movable part 13 to have different usage angles, the rotation angle of the movable part 13 relative to the fixed part 12 is different when the latching protrusion 141 engages with the slots 142 at different positions. For example, the three usage angles are 0° (horizontal airflow), 45° (tilted airflow), and 90° (vertical upward airflow). When airflow is emitted at these three angles, the movable part 13 and the fixed part 12 can be locked together by a locking structure 14, that is, the latching protrusion 141 and the slots 142 engage with each other. Of course, the number of slots 142 can also be three or more, and is not limited here.

[0055] According to one embodiment of the present invention, the fixing part 12 has a double-layer structure. Exemplarily, the fixing part 12 includes a fixing inner shell 121 and a fixing outer shell 122. The fixing inner shell 121 is made of heat-insulating material, while the fixing outer shell 122 can be made of non-heat-insulating material, thus saving on the amount of heat-insulating material used. In one embodiment, the fixing inner shell 121 includes a first inner shell 1211 and a second inner shell 1212. The first inner shell 1211 and the second inner shell 1212 are connected and enclosed to form a mounting cavity for mounting structures such as the heating element 124, the motor 125, and the circuit board 126.

[0056] Optionally, the movable part 13 has a double-layer structure, which includes a movable inner shell and a movable outer shell. The movable inner shell is made of heat-insulating material, while the movable outer shell can be made of non-heat-insulating material and has no heat-insulating requirements. In this way, the double-layer structure can save the amount of heat-insulating material used.

[0057] In one embodiment, the active part 13 further includes an air outlet cover that covers the air outlet 131. The air outlet cover has multiple mesh holes to improve the uniformity of airflow.

[0058] According to one embodiment of the present invention, when the fixing part 12 has a double-layer structure, an ion generator 123 is installed between the inner layer and the outer layer of the fixing part 12, making full use of the product space and resulting in a compact structure. The ion generator 123 is set in the fixing part 12, and the wiring between the ion generator 123 and the circuit board 126 will not be affected by the change of the air outlet angle.

[0059] According to one embodiment of this utility model, a sealing structure 15 is provided between the fixed part 12 and the movable part 13. The sealing structure 15 can be a sealing ring, a threaded structure, a labyrinth-type sealing structure, etc., and is not limited here. Taking the labyrinth-type sealing structure as an example, the labyrinth-type sealing structure is a non-contact sealing device. By designing a complex flow path (such as tortuous grooves or gaps), it increases the resistance to fluid leakage, thereby effectively reducing leakage. The labyrinth seal consists of multiple annular toothed plates and gaps. A tiny gap is formed between the toothed plates and the rotating shaft or stationary part. When the fluid passes through, it needs to undergo multiple expansions, contractions, and deflections, and the energy is gradually dissipated, significantly reducing the leakage and effectively preventing hot air leakage from the blower.

[0060] According to one embodiment of this utility model, a connecting structure is provided at the air outlet 131 for detachably installing hair styling accessories. For example, hair styling accessories such as curling irons, straighteners, or volumizing combs are detachably connected to the movable part 13 via the connecting structure. Thus, rotating the movable part 13 allows the hair styling accessory to be rotated to a convenient operating angle. The connecting structure can be a threaded structure, a snap-fit ​​structure, a slot structure, etc., and is not limited thereto.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
