Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a folding hair dryer. Background Technology

[0002] Hair dryers, such as hairdryers, are widely used in daily life. A hairdryer generally consists of two parts: a handle for the user to hold and a nozzle for blowing heated air. Traditional hairdryers come in two forms: non-foldable and foldable. Non-foldable hairdryers are generally L-shaped, fixing the relative positions of the handle and nozzle, but they are bulky and difficult to store. Foldable hairdryers can be in an L-shaped working state or folded from the L-shape, bringing the handle and nozzle closer together. However, this type of hairdryer can only operate in one of these states, and turning the handle requires more effort, limiting its functionality. Utility Model Content

[0013] The main body of the fan is housed within the fan support frame;

[0014] The rotation of the duct assembly causes the fan bracket to rotate relative to the pivot structure, so that the fan body can rotate as well.

[0015] Optionally, the folding hair dryer further includes a heating component disposed within the hair shaft assembly, the heating component comprising:

[0016] An air guide duct, one end of which is connected to the fan bracket and the other end of which extends toward the air outlet of the air duct assembly; the first mating part includes a hook at one end of the air guide duct, which is engaged with the corresponding locking hole.

[0017] The heating element is disposed inside the air guide duct and located at one end near the fan assembly.

[0018] Optionally, the end of the fan bracket facing the air guide tube is formed with 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 heating assembly also includes a sealing element, which is disposed at the end of the air guide tube that abuts against the bottom of the guide groove to seal between the air guide tube and the bottom of the guide groove.

[0020] Optionally, the air duct 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.

[0029] The technical solution provided by this utility model has the following beneficial effects:

[0030] This utility model provides a folding hair dryer, including a nozzle assembly, a handle assembly, a pivot structure, and a fan 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 folding 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, and the folding hair dryer has 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 folding hair dryer in the extended state and making it easier for the user to operate. Furthermore, by making the length of the air duct assembly shorter than that of the handle assembly, and by placing the fan assembly closer to the air outlet of the air duct assembly, compared to the traditional method of placing the fan assembly inside the handle assembly, the airflow blown out by the fan assembly can obviously enter the air duct assembly quickly, resulting in a shorter air outlet path and thus higher air outlet efficiency.

[0045] This utility model provides a folding hair dryer 100. For details, please refer to [link / reference needed]. Figures 1 to 3 As shown, in this embodiment, the folding hair dryer 100 includes a blower assembly 1, a handle assembly 2, a pivot structure 3, and a fan assembly. The length of the blower assembly 1 along its axial direction is less than the length of the handle assembly 2 along its axial direction. The pivot structure 3 pivotally connects the blower assembly 1 and the handle assembly 2, allowing the blower assembly 1 and the handle assembly 2 to rotate relative to each other, to have an extended state and a bent state. In the extended state, the blower 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 blower assembly 1 and the central axis of the handle assembly 2. The fan assembly is disposed inside the blower assembly 1.

[0046] In this embodiment, the air nozzle 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 air nozzle assembly 1 and the handle assembly 2, enabling the folding hair dryer 100 to operate in both extended and bent states. In the extended state, the air nozzle assembly 1 and the handle assembly 2 are arranged in a straight line, and the folding hair dryer 100 has a rod-like structure. This allows for easy connection and installation of hair-combing accessories (such as straighteners or curling irons) at the air outlet, ensuring better airflow along the hair's direction and facilitating combing or curling. Furthermore, the rotation center of the pivot structure 3 is offset to the same side of the central axis of both the air nozzle assembly 1 and the handle assembly 2. In the extended state, the pivot structure 3 does not occupy axial space along the axes of the air nozzle assembly 1 and the handle assembly 2, ensuring a smaller axial dimension of the folding hair dryer 100 in the extended state, making it easier for the user to operate.

[0047] The hairdryer assembly 1 and handle assembly 2 can operate at any bending angle and at different angles, making the folding hairdryer 100 more versatile in its operation. When bent, the central axis of the hairdryer 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 hairdryer assembly 1 and handle assembly 2 can operate in an "L" or "V" shape to meet the needs of special usage environments. The wider adjustability of the hairdryer assembly 1 and handle assembly 2 better meets the diverse needs of different users, making it more convenient and providing a better user experience. Furthermore, by making the length of the air duct assembly 1 shorter than the length of the handle assembly 2, the distance between the fan assembly 5 and the air outlet 11 of the air duct assembly 1 is closer. Compared with the traditional method of placing the fan assembly inside the handle assembly, the airflow blown out from the fan assembly 5 can obviously enter the air duct assembly 1 quickly, the air outlet path is shorter, and therefore the air outlet efficiency is higher.

[0048] Furthermore, when the blower assembly 1 is shorter, the blower assembly 5 can be at least partially housed within the pivot structure 3, thereby further compressing the structure and making the entire folding blower 100 smaller.

[0049] The air duct assembly 1 is provided with an air outlet 11, which can be located at the end or periphery of the air duct assembly 1. Preferably, the air outlet 11 is formed at the axial end of the air duct assembly 1. An air inlet 21 can be provided on the air duct assembly 1, and / or the handle assembly 2, and / or the pivot structure 3. Preferably, the air inlet 21 is provided on the handle assembly 2. After the airflow enters the handle assembly 2 through the air inlet 21, it flows along the handle assembly 2 to the pivot structure 3, enters the air duct assembly 1 through the pivot structure 3, and is blown out from the air outlet 11 along the air duct assembly 1 for user use.

[0050] By adjusting the relative angle between the nozzle assembly 1 and the handle assembly 2, the folding hair dryer 100 can switch between an extended state and a bent state to meet different user needs. Preferably, combined with Figure 1 and Figure 2 As shown, the central axis of the blower assembly 1 and the central axis of the handle assembly 2 have an angle θ, wherein, preferably, the angle θ is 60° to 180°. The angle between the blower assembly 1 and the handle assembly 2 can be adjusted by driving the blower assembly 1 and / or the handle assembly 2 to rotate via a drive mechanism, making the switching of various working states of the folding hair dryer 100 more intelligent; alternatively, the angle between the blower assembly 1 and the handle assembly 2 can be adjusted manually, resulting in a simpler structure and lower cost.

[0051] 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.

[0052] 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 handle assembly 1 is held and rotated, 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 folding hair dryer 100.

[0053] 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 external structure of the folding hair dryer 100 is more symmetrical and aesthetically pleasing when the hair dryer assembly 1 and the handle assembly 2 are in the bent and extended states, and the grip is also more comfortable.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] The main function of the blower assembly 5 is to guide the airflow from the outside of the folding hair dryer 100 into the handle assembly 2, and then blow it into the hair dryer 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 hair dryer assembly 1, thereby forming a directional airflow that can act on the hair.

[0058] When the handle assembly 2 has an air inlet 11, the air inlet end of the fan assembly 5 is connected to the handle assembly 2, and the air outlet end of the fan 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 fan assembly 5 to rotate together, while maintaining the connection between the air inlet end of the fan assembly 5 and the handle assembly 2. This ensures that regardless of the working posture of the folding hair dryer 100, the fan assembly 5 can better maintain its relative position with the air duct assembly 1, ensuring that the airflow blown by the fan assembly 5 can better flow into the air duct assembly 1, resulting in less wind resistance and higher air output efficiency.

[0059] Furthermore, in the extended state, the air duct assembly 1 and the handle assembly 2 are coaxially arranged. The central axis of the fan assembly 5 is in the same plane as and intersects with the central axis of the air duct assembly 1 and the central axis of the handle assembly 2. Since the folding hair dryer 100 needs to maintain docking and communication with both the air duct assembly 1 and the handle assembly 2 simultaneously when switching between the extended and bent states, when at least a portion of the fan assembly 5 is housed within the pivot structure 3, the central axis of the fan assembly 5 cannot be completely parallel to the central axis of the air duct assembly 1. Therefore, the fan assembly 5 is tilted relative to the air duct assembly 1 to better accommodate the switching requirements between the extended and bent states of the folding hair dryer 100.

[0060] Among them, combined Figure 5 and Figure 6 As shown, the fan assembly 5 is provided with a first engaging portion 511 and a first rotating portion 512. The first engaging portion 511 is located at the air outlet end of the fan assembly 5 and is used to engage 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 assembly 5 and is adapted to be rotatably connected to the pivot shaft of the pivot structure 3. This allows one end of the fan assembly 5 to be fixed inside the air duct assembly 1, while the other end is rotatably mounted inside the pivot structure 3. When the folding blower 100 switches between working states, the fan assembly 5 can rotate around the rotation center of the pivot structure 3.

[0061] Preferably, combined with Figures 5 to 7 As shown, the fan assembly 5 includes a fan bracket 51 and a fan body 52. ​​The fan bracket 51 is cylindrical with openings at both ends. The first locking part 511 includes a locking hole 5111 at the end of the fan bracket 51 facing the fan duct assembly. The first rotating part 512 includes a rotating hole 5121 on the outer periphery of the fan bracket 51. The fan body 52 is disposed inside the fan bracket 51. The rotation of the fan duct assembly 1 causes the fan bracket 51 to rotate relative to the pivot structure 3, so that the fan body 52 can rotate together. The fan bracket 51 can more stably fix the fan body 52 inside the fan duct assembly 1, so as to better ensure the airflow direction.

[0062] Furthermore, combined Figures 3 to 5 As shown, the folding 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 correspondingly engaged with a 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 engaging 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.

[0063] 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.

[0064] 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, 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.

[0065] For pivoting structures, specifically, in combination Figure 5 and Figure 6 As shown, the duct assembly 1 has a first connecting end and a first free end that are opposite each other along its axial direction, and the handle assembly 2 has a second connecting end and a second free end that are opposite each other along its axial direction. A pivot structure 3 connects the first connecting end and the second connecting end.

[0066] The pivot structure 3 includes a first rotating part 31, a second rotating part 32, and a blocking part 34. The first rotating part 31 is located at the first connecting end of the air duct assembly 1. The second rotating part 32 is located at the second connecting end of the handle assembly 2 and is rotatably connected to the first rotating part 31. The first rotating part 512 is coaxially rotatably connected to the first rotating part 31 and the second rotating part 32. The blocking part 34 is rotatably connected to the rotatable connection between the first rotating part 31 and the second rotating part 32. In the extended state, the first connecting end and the second connecting end at least partially abut against each other, so that the blocking part 34 is completely located within the air duct assembly 1 and the handle assembly 2. When switching from the extended state to the bent state, the first side of the blower assembly 1 and the first side of the handle assembly 2 move closer to each other, while the second side of the blower assembly 1 and the second side of the handle assembly 2 move further apart from each other, so that the first connecting end and the second connecting end are at least partially spaced apart. The blocking part 34 can block the gap between the first connecting end and the second connecting end, so that when in the bent state, at least part of the blocking part 34 is exposed from the blower assembly 1 and the handle assembly 2, and the blocking part 34 ensures the sealing of the folding hair dryer 100.

[0067] Furthermore, combined Figure 6As shown, the first rotating part 31 includes a first rotating sleeve 311 disposed at the first connecting end. The first rotating sleeve 311 protrudes from the shaft end of the air duct assembly 1 and is eccentrically disposed in the radial direction of the air duct assembly 1. The axial direction of the first rotating sleeve 311 is perpendicular to the rotation plane where the air duct assembly 1 and the handle assembly 2 are located. Preferably, the first rotating sleeve 311 is integrally disposed with the air duct assembly 1. The handle assembly 2 includes a first half-shell 22 and a second half-shell 23 connected to each other. The second rotating part 32 includes a first sleeve body 3211 and a second sleeve body 3212 connected to each other. The first sleeve body 3211 is connected to the first half-shell 22, and the second sleeve body 3212 is connected to the second half-shell 23. The first sleeve body 3211 and the second sleeve body 3212 are respectively rotatably connected to the two ends of the first rotating sleeve 311 along its axial direction to facilitate assembly. Preferably, the first body 3211 and the first half-shell 22 are integrally formed, and the second body 3212 and the second half-shell 23 are integrally formed, so that there are fewer assembly parts and assembly is more convenient.

[0068] Specifically, the first rotating sleeve 311 is annularly arranged, and at least a portion of the first rotating sleeve 311 protrudes from the air duct assembly 1 radially, such that the central axis of the first rotating sleeve 311 is located on the first side of the air duct assembly 1. Furthermore, a partition is provided on the inner annular side of the first rotating sleeve 311, and a rotating column 3111 is provided on the partition. The rotating column 3111 is located at the center of the first rotating sleeve 311, and the air duct assembly 1 and the handle assembly 2 are respectively located at the two axial ends of the rotating column 3111, respectively, to be rotatably connected to the two axial ends of the rotating column 3111.
