[0002] Hair dryers generally consist of a handle, a nozzle, and a fan housed within the handle. The handle is for the user to hold, while the nozzle blows heated air. Traditional hair dryers, with the fan located inside the handle, generate significant vibration when the user holds the handle, leading to hand numbness after prolonged use and severely impacting the user experience. Utility Model Content

[0003] Therefore, this utility model aims to solve the problem that traditional hair dryers cause strong vibrations in the handle, which can easily lead to numbness in the user's hands and seriously affect the user experience.

[0004] To achieve the above objectives, this utility model proposes a hair dryer, comprising:

[0005] Air duct assembly and handle assembly;

[0006] A pivoting structure pivotally connects the air duct assembly and the handle assembly, allowing the air duct assembly and the handle assembly to rotate relative to each other to have an extended state and a bent state. In the extended state, the air duct assembly and the handle assembly are arranged in a straight line, and the rotation center of the pivoting structure is offset on the same side of the central axis of the air duct assembly and the central axis of the handle assembly. A fan assembly, at least partially located within the air duct assembly, includes a fan bracket, a fan body mounted on the fan bracket, and a shock-absorbing structure located between the fan body and the fan bracket. The shock-absorbing structure has a wire-passing hole adapted for a conductor wire from the fan body to pass through.

[0007] Optionally, the shock absorption structure includes a shock absorption cylinder and a wire guide block disposed on the outer periphery of the shock absorption cylinder. The wire guide hole is disposed on the wire guide block. The shock absorption cylinder is fixedly sleeved on the outer side of the fan body and forms a wire guide gap with the inner side of the fan bracket. The wire guide block is disposed in the wire guide gap, so that the conductor wire of the fan body can pass through the wire guide gap and pass through the wire guide block to the outside of the fan assembly.

[0008] Optionally, the wire guide block and the shock absorber are integrally formed.

[0009] Optionally, both the fan support and the shock absorber are cylindrical and coaxial with the fan body.

[0010] Optionally, the fan body includes a fan casing, and the shock absorber is sleeved on the outside of the fan casing, with openings at both ends covering the two ends of the fan casing along its axial direction.

[0011] The inner side of the fan bracket has a first stop protrusion. The edge of one end of the shock absorber abuts against the first stop protrusion. The outer circumference of the other end of the shock absorber has an annular protrusion. The annular protrusion abuts against the inner circumference of the fan body to form an axial seal. The annular protrusion and the first stop protrusion form the wire passage gap. The wire passage block is located at the end of the shock absorber with the annular protrusion.

[0012] Optionally, the wire hole is at least partially notched at the end away from the first stop protrusion;

[0013] The fan bracket is at least partially hollowed out at the corresponding notch, so that when the conductor wire of the fan body passes through the notch, it can pass out from the hollowed-out area along the radial direction of the shock absorber.

[0014] Optionally, the outer periphery of the shock absorber is provided with a plurality of protrusions, the plurality of protrusions being located within the wire passage gap, and at least a portion of the protrusions abutting against the inner sidewall of the fan bracket.

[0015] Optionally, the fan bracket is provided with a first snap-fit ​​part and a first rotating part. The first snap-fit ​​part is provided at the air outlet end of the fan bracket and is used to snap-fit ​​with the first mating part in the air duct assembly. The first rotating part is provided on the outer periphery of the fan assembly and is adapted to be rotatably connected to the pivot shaft of the pivot structure.

[0016] Optionally, the first snap-fit ​​portion includes a snap-fit ​​hole at one end of the fan bracket facing the fan duct assembly; the first rotating portion includes a rotating hole on the outer periphery of the fan bracket; the rotation of the fan duct assembly drives the fan bracket to rotate relative to the pivot structure, so that the fan body can rotate together.

[0017] Optionally, the hair dryer further includes an air guide tube disposed within the air tube assembly, one end of which is connected to the fan bracket and the other end of which extends toward the air outlet of the air tube assembly; the first mating part includes a hook disposed at one end of the air guide tube, the hook being engaged with the corresponding locking hole.

[0018] The end of the fan bracket facing the air guide tube has a guide groove, and the locking hole is provided on the outer wall of the guide groove; the end of the air guide tube is inserted into the guide groove, and the hook engages with the corresponding locking hole.

[0019] The hair dryer also includes a sealing element, which is disposed at the end of the air guide tube that abuts against the guide groove to seal between the air guide tube and the bottom of the guide groove.

[0020] The technical solution provided by this utility model has the following beneficial effects:

[0021] This utility model provides a hair dryer comprising a nozzle assembly, a handle assembly, a pivot structure, and a blower assembly. The pivot structure connects the nozzle assembly and the handle assembly, allowing them to rotate relative to each other. This adjusts the angle between the nozzle and handle assemblies, enabling the hair dryer to operate in both extended and bent states. In the extended state, the nozzle and handle assemblies are arranged in a straight line, giving the hair dryer a rod-like structure. This allows for easy connection and installation of hair combing attachments at the air outlet, ensuring better airflow along the hair's direction for easier combing or curling. Furthermore, the pivot structure's rotation center is offset to the same side of the central axis of both the nozzle and handle assemblies. In the extended state, the pivot structure does not occupy axial space along the axes of the nozzle and handle assemblies, ensuring a smaller axial dimension of the hair dryer and easier user operation. Furthermore, by incorporating the fan assembly, at least partially, within the airflow tube assembly, compared to the traditional method of integrating the fan assembly into the handle assembly, the airflow from the fan assembly can be quickly expelled from the airflow tube assembly. This results in a shorter airflow path, lower airflow resistance, and thus higher airflow efficiency. Moreover, the vibrations from the fan assembly do not directly affect the handle assembly; being further away from the user's hand, the vibrations are less noticeable. The fan assembly also includes a shock-absorbing structure, which effectively reduces vibration, improving grip comfort and user experience. Additionally, the shock-absorbing structure features cable routing holes, allowing for the neat arrangement of the fan body's wiring, resulting in a more compact internal structure and easier assembly.

[0036] This utility model provides a hair dryer 100. For details, please refer to [link / reference needed]. Figures 1 to 3 As shown, in this embodiment, the hair dryer 100 includes a hair shaft assembly 1, a handle assembly 2, a pivot structure 3, and a fan assembly 5. The pivot structure 3 pivotally connects the hair shaft assembly 1 and the handle assembly 2, allowing the hair shaft assembly 1 and the handle assembly 2 to rotate relative to each other, having an extended state and a bent state. In the extended state, the hair shaft assembly 1 and the handle assembly 2 are arranged in a straight line, and the rotation center of the pivot structure 3 is offset on the same side of the central axis of the hair shaft assembly 1 and the central axis of the handle assembly 2. At least a portion of the fan assembly 5 is located inside the hair shaft assembly 1. The fan assembly 5 includes a fan bracket 51, a fan body 52 disposed on the fan bracket 51, and a shock-absorbing structure 53 disposed between the fan body 52 and the fan bracket 51. The shock-absorbing structure 53 has a wire hole adapted for the wires on the fan body 52 to pass through.

[0037] In this embodiment, the hair dryer assembly 1 and the handle assembly 2 are connected by a pivot structure 3, allowing them to rotate relative to each other. This adjusts the angle between the hair dryer assembly 1 and the handle assembly 2, enabling the hair dryer 100 to operate in both extended and bent states. In the extended state, the hair dryer assembly 1 and the handle assembly 2 are arranged in a straight line, and the hair dryer 100 has a rod-like structure. This allows for easy connection and installation of hair combing accessories at the air outlet, ensuring better airflow along the hair's direction for easier combing or curling. Furthermore, the rotation center of the pivot structure 3 is offset to the same side of the central axis of the hair dryer assembly 1 and the central axis of the handle assembly 2. In the extended state, the pivot structure 3 does not occupy axial space along the axes of the hair dryer assembly 1 and the handle assembly 2, ensuring a smaller axial dimension of the hair dryer 100 in the extended state, making it easier for the user to operate.

[0038] Furthermore, by placing the blower assembly 5 at least partially within the air duct assembly 1, compared to the traditional method of placing the blower assembly 5 within the handle assembly 2, the airflow from the blower assembly 5 can obviously be quickly blown out of the air duct assembly 1, resulting in a shorter airflow path, lower airflow resistance, and thus higher airflow efficiency. Moreover, the vibration of the blower assembly 5 does not directly affect the handle assembly 2, being further away from the user's hand, thus reducing the vibration felt by the user. The blower assembly 5 also includes a shock-absorbing structure 53, which effectively reduces vibration, improving grip comfort and user experience. Furthermore, the shock-absorbing structure 53 has a cable guide hole, which allows for the formation of a neat guide wire for the blower body 52, making the internal structure of the hair dryer 100 more compact and easier to assemble.

[0039] The hair dryer assembly 1 and the handle assembly 2 can operate at any bending angle and at different angles, making the hair dryer 100 more versatile in its operation. When bent, the central axis of the hair dryer assembly 1 and the central axis of the handle assembly 2 form an angle, which is either a minor angle (greater than 0° and less than 180°) or a major angle (greater than 180° and less than 360°). The hair dryer assembly 1 and the handle assembly 2 can operate in an "L" or "V" shape to meet the needs of special usage environments. The wider adjustability of the hair dryer assembly 1 and the handle assembly 2 better meets the diverse needs of different users, making it more convenient and providing a better user experience.

[0040] In one embodiment, the rotation plane of the air duct assembly 1 (i.e., the plane through which the central axis of the air duct assembly 1 rotates) and the rotation plane of the handle assembly 2 (i.e., the plane through which the central axis of the handle assembly 2 rotates) can be set to be non-coplanar. For example, the rotation plane of the air duct assembly 1 and the rotation plane of the handle assembly 2 can be arranged parallel and / or intersecting, so that the air duct assembly 1 and the handle assembly 2 are misaligned in the rotation direction, thereby better realizing large-angle rotation. And / or, one of the air duct assembly 1 and the handle assembly 2 can rotate, and the angle between the two can be changed by the relative rotation of the air duct assembly 1 and the handle assembly 2.

[0041] Preferably, during the relative rotation of the hair dryer assembly 1 and the handle assembly 2, the central axis of the hair dryer assembly 1 and the central axis of the handle assembly 2 are always located on the same plane. The support between the hair dryer assembly 1 and the handle assembly 2 remains aligned during rotation. Therefore, when the hair dryer assembly 1 is rotated while holding the handle assembly 2, the hair dryer assembly 1 will not tilt to one side, making rotation easier and less strenuous, and providing a better user experience. Furthermore, it does not occupy excessive space along the axis of the pivot structure 3, resulting in a more compact size for the hair dryer 100.

[0042] The shape and size of the hair dryer assembly 1 and the handle assembly 2 are not specifically limited, and can be square, polygonal, or irregular in shape. Preferably, both the hair dryer assembly 1 and the handle assembly 2 are cylindrical and have the same diameter, so that the hair dryer 100 has a more symmetrical and aesthetically pleasing shape when it is in a bent or extended state, and is also more comfortable to hold.

[0043] The air duct assembly 1 and the handle assembly 2 are set to rotate on a horizontal plane. Preferably, the pivot axis of the pivot structure 3 is set 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 air duct assembly 1 and / or the central axis of the handle assembly 2, so that the air duct assembly 1 and the handle assembly 2 rotate more smoothly and are not easy to twist or shake.

[0044] Specifically, when rotating from the extended state to the bent state, the first side of the duct assembly and the first side of the handle assembly move towards each other. In the extended state, on the orthographic projection along the axis of the pivot structure 3, the projections of the duct assembly 1 and the handle assembly 2 are both located on the same side of the projection of the plane containing the pivot axis of the pivot structure 3; that is, the first side of the duct assembly 1 and / or the first side of the handle assembly 2 are both located on the plane containing the pivot axis, or both are located on the first side of the plane containing the pivot axis. When the diameters of the duct assembly 1 and the handle assembly 2 are equal, in the extended state, the first side of the duct assembly 1 and the first side of the handle assembly 2 are flush, and the pivot axis is exactly located on the plane containing the first side of the duct assembly 1 and the first side of the handle assembly 2.

[0045] Alternatively, the pivot axis of the pivot structure 3 is located exactly on the straight line of the first side of the air duct assembly 1 and / or the handle assembly 2. In the radial direction along the air duct assembly 1 and / or the handle assembly 2, the portion of the pivot structure 3 protruding from the air duct assembly 1 and / or the handle assembly 2 is less, thus making the structure more compact in the radial direction and thus smaller in volume.

[0046] For wind turbine component 5, combined Figure 3 and Figure 4 As shown, it is mainly used to guide airflow from the outside of the hair dryer 100 into the handle assembly 2, and blow it into the blower assembly 1 through the air outlet of the blower assembly 5, so that the airflow can be blown out from the air outlet of the blower assembly 1, thereby forming a directional airflow that can act on the hair.

[0047] When the handle assembly 2 has an air inlet 21, the air inlet end of the blower assembly 5 is connected to the handle assembly 2, and the air outlet end of the blower assembly 5 is connected to the air duct assembly 1. When switching between the extended and bent states, the rotation of the air duct assembly 1 can drive the blower assembly 5 to rotate together, while maintaining the connection between the air inlet end of the blower assembly 5 and the handle assembly 2. This ensures that regardless of the working posture of the hair dryer 100, the blower assembly 5 can better maintain its relative position with the air duct assembly 1, ensuring that the airflow blown by the blower assembly 5 can better flow into the air duct assembly 1, resulting in less wind resistance and higher air output efficiency.

[0048] Moreover, such as Figure 3 As shown, in the extended state, the hair dryer assembly 1 and the handle assembly 2 are coaxially arranged. The central axis of the blower assembly 5 is in the same plane as the central axis of the hair dryer assembly 1 and the central axis of the handle assembly 2, and intersects with them. Since the hair dryer 100 needs to maintain docking and communication with both the hair dryer assembly 1 and the handle assembly 2 when switching between the extended and bent states, the central axis of the blower assembly 5 cannot be completely parallel to the central axis of the hair dryer assembly 1 when at least a portion of the blower assembly 5 is housed within the pivot structure 3. Therefore, the blower assembly 5 is tilted relative to the hair dryer assembly 1 to better accommodate the switching requirements between the extended and bent states of the hair dryer 100.

[0049] Preferably, combined with Figures 5 to 7As shown, the vibration damping structure 53 includes a vibration damping cylinder 531 and a wire guide block 532 disposed on the outer periphery of the vibration damping cylinder 531. A wire guide hole 5321 is disposed on the wire guide block 532. The vibration damping cylinder 531 is fixedly sleeved on the outer side of the fan body 52 and forms a wire guide gap with the inner side of the fan bracket 51. The wire guide block 532 is disposed in the wire guide gap, so that the conductor wire of the fan body 52 can pass through the wire guide gap and pass through the wire guide block 532 to the outside of the fan assembly 5. One end of the conductor wire of the fan body 52 is connected to the end near its air inlet end, and the other end of the conductor wire of the fan body 52 can be inserted into the wire guide gap to be accommodated between the vibration damping cylinder 531 and the fan bracket 51, without being exposed on the outside of the fan assembly 5, and the conductor wire will not be scattered haphazardly. Finally, the wire passes through the through hole 5321 to connect with the circuit structure inside the hair dryer 100, making it less prone to errors in the connection of the conductor wire.

[0050] More preferably, the wire guide block 532 and the shock absorber 531 are integrally formed. The wire guide block 532 and the shock absorber 531 are manufactured as a single piece, which effectively reduces the number of assembly parts and improves assembly efficiency. Furthermore, the wire guide block 532 is positioned on the shock absorber 531, making the wire guide hole 5321 more stable and less prone to shaking, thus ensuring a more stable and reliable connection of the conductor wire.

[0051] Both the fan bracket 51 and the shock absorber 531 are cylindrical and coaxial with the fan body 52. ​​This ensures that when the fan bracket 51 is installed inside the fan casing assembly 1, the rotation of the fan body 52 will not cause polarization, thus better guaranteeing the working stability of the fan assembly 5.

[0052] Furthermore, the fan body 52 includes a fan casing, and a shock absorber 531 is sleeved on the outside of the fan casing, with openings at both ends covering the axial ends of the fan casing. The shock absorber 531 can be configured as an elastic rubber component. By firmly covering the outside of the fan body 52 with the shock absorber 531, the fixation between the shock absorber 531 and the fan body 52 is more reliable, and the two are less prone to relative movement, thus providing better shock absorption for the fan body 52.

[0053] Moreover, combined Figure 6 and Figure 7As shown, a first stop protrusion 513 protrudes from the inner side of the fan bracket 51, located near the air inlet end of the fan body 52. ​​One end of the shock absorber 531 abuts against the first stop protrusion 513, and the outer periphery of the other end of the shock absorber 531 has an annular protrusion 5311. The annular protrusion 5311 abuts against the inner periphery of the fan body 52 to form an axial seal. A wire passage gap is formed between the annular protrusion 5311 and the first stop protrusion 513, and a wire passage block 532 is located at the end of the shock absorber 531 with the annular protrusion 5311. By sealing the inner side of the wire passage gap with the annular protrusion 5311, external contaminants can be prevented from entering the fan body 52 and affecting its operation, and the connection between the fan bracket 51 and the shock absorber 531 can be ensured reliably.

[0054] Furthermore, such as Figure 5 As shown, the end of the wire hole 5321 away from the first stop protrusion 513 is at least partially notched. The fan bracket 51 is at least partially hollowed out at the corresponding notch, so that when the conductor wire of the fan body 52 passes through the notch, it can pass through the hollowed-out area radially along the shock absorber 531. After passing through the fan assembly 5, the conductor wire does not occupy the axial space of the fan assembly 5, but is led out from the circumferential side of the fan assembly 5, so as to better suit the electrical connection with the internal circuit structure of the hair dryer 100.

[0055] In addition, combined Figure 6 and Figure 7 As shown, multiple protrusions 5312 are provided on the outer periphery of the shock-absorbing cylinder 531. The multiple protrusions 5312 are located within the wire passage gap, and at least some of the protrusions 5312 abut against the inner sidewall of the fan bracket 51. By abutting against the fan bracket 51 with the multiple protrusions 5312, the strength of the peripheral sidewall of the fan bracket 51 can be improved. At the same time, the multiple protrusions 5312 can play a buffering role to effectively reduce the vibration intensity transmitted to the fan bracket 51 during the operation of the fan body 52, thereby reducing the vibration intensity of the hair dryer 100.

[0056] Moreover, combined Figures 3 to 5 As shown, the fan bracket 51 is provided with a first snap-fit ​​portion 511 and a first rotating portion 512. The first snap-fit ​​portion 511 is located at the air outlet end of the fan bracket 51 and is used to snap-fit ​​with the first mating portion 611 inside the air duct assembly 1. The first rotating portion 512 is located on the outer periphery of the fan bracket 51 and is adapted to be rotatably connected to the pivot shaft of the pivot structure 3. This allows one end of the fan bracket 51 to be fixed inside the air duct assembly 1, while the other end is rotatably installed inside the pivot structure 3. When the hair dryer 100 switches between working states, the fan assembly 5 can rotate around the rotation center of the pivot structure 3.

[0057] Preferably, combined with Figure 5 and Figure 6 As shown, the fan bracket 51 is a cylindrical structure with openings at both ends. The first locking portion 511 includes a locking hole 5111 at the end of the fan bracket 51 facing the fan duct assembly. The first rotating portion 512 includes a rotating hole 5121 on the outer periphery of the fan bracket 51. The fan body 52 is housed within the fan bracket 51. Rotation of the fan duct assembly 1 causes the fan bracket 51 to rotate relative to the pivot structure 3, allowing the fan body 52 to rotate as well. The fan bracket 51 provides a more stable fixation of the fan body 52 within the fan duct assembly 1, better ensuring the airflow direction.

[0058] Furthermore, combined Figure 3 and Figure 4 As shown, the hair dryer 100 also includes a heating component 6 disposed within the air duct assembly 1. The heating component 6 includes an air guide duct 61 and a heating element 62. One end of the air guide duct 61 is connected to the fan bracket 51, and the other end extends toward the air outlet of the air duct assembly 1. The first mating part 611 includes a hook 6111 disposed at one end of the air guide duct 61, which is engaged with a corresponding locking hole 5111. The heating element 62 is disposed within the air guide duct 61 and located near the end of the fan assembly 5. The fan bracket 51 is fixed to the air guide duct 61 by the engagement of the hook 6111 with the locking hole 5111. This allows the airflow from the fan assembly 5 to flow more effectively toward the heating element 62 after entering the air guide duct 61, and after being heated by the heating element 62, the airflow is blown out from the air guide duct toward the air outlet of the air duct assembly 1.

[0059] Furthermore, a guide groove is formed at the end of the fan bracket 51 facing the guide tube 61, with the groove opening facing the guide tube. A locking hole 5111 is provided on the outer wall of the guide groove, and the end of the guide tube 61 is inserted into the guide groove, such that the hook 6111 engages with the corresponding locking hole 5111. The insertion and engagement of the guide tube 61 with the guide groove ensures the sealing of the connection between the guide tube 61 and the fan bracket 51. The heating assembly 6 also includes a sealing element, located at the end of the guide tube 61 that abuts against the guide groove, to seal between the guide tube 61 and the bottom of the guide groove. The bottom of the guide groove is the side opposite to its opening. The sealing element is a sealing ring, which seals the gap between the air guide tube 61 and the guide groove. This further ensures the sealing effect at the connection between the air guide tube 61 and the fan bracket 51, so that after the airflow is blown out from the fan assembly 5, it all enters the air tube. The airflow will not flow arbitrarily, but will flow better toward the heating element 62. All the airflow can flow better through the heating element 62 before flowing out of the air tube assembly 1. Therefore, the temperature uniformity of the hot airflow is better, which can better ensure the hair drying effect.

[0060] Furthermore, the air guide duct 61 has a main body end and a connecting end that are arranged opposite to each other along the axial direction of the air duct assembly 1. The main body end is fixed to the inner side of the air duct assembly 1, and its central axis is parallel to the central axis of the air duct assembly 1. The connecting end is connected to the fan bracket 51, and its central axis is set at an angle to the central axis of the main body end. By bending and tilting the end of the air guide duct 61, the air guide duct 61 can be better connected to the fan assembly 5, avoiding the need to make the fan body 52 into an irregular shape, thus saving costs.

[0061] 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.
