Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, specifically relating to a rotating component and a foldable hair dryer. Background Technology

[0002] Hair dryers are devices that draw in gas, heat the gas, and output it externally. Their daily use is for drying wet hair. Existing hair dryers with rotating structures have rotating heads, which often use hinges to achieve rotation. However, this type of structure is cumbersome to install and disassemble. Furthermore, due to the lack of a damping structure during rotation, it can only achieve a small number of specific angles of rotation. Among rotating heads with multi-layered structures, the installation structure is relatively complex and inconvenient to install and disassemble. Therefore, it is necessary to develop a rotating component and a foldable hair dryer. Utility Model Content

[0003] The purpose of this utility model is to provide a rotating component and a foldable hair dryer to solve the above-mentioned technical problems. The first mounting frame and the second mounting frame, which are assembled from two modules, allow the rotating head to be installed with the first connecting structure through the first mounting frame and the second mounting frame respectively. This restricts the first connecting structure within the space formed by the two, reducing the installation difficulty. At the same time, the first connecting structure provides a fulcrum for the rotating head to rotate, so that the rotating head can be rotated accordingly to achieve a folded state. This allows for switching between different working modes to meet different scenario requirements.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A rotating assembly includes a rotating head and a first connection structure movably connected to the rotating head and providing a rotation fulcrum;

[0006] The rotating head includes a first mounting frame and a second mounting frame connected to the first mounting frame to form a circumferentially continuous arrangement;

[0007] The first connecting structure is movably connected within the area enclosed by the first mounting frame and the second mounting frame. The first connecting structure provides a fulcrum for the rotation of the rotating head and restricts its movement path; the ratio of the surface area of ​​the first mounting frame to the surface area of ​​the second mounting frame is 4:1 to 5:1; the first mounting frame and the second mounting frame are connected by screws; the first and second mounting frames, which are assembled from two modules, allow the rotating head to be installed separately through the first and second mounting frames, thereby restricting the first connecting structure within the space formed by the two, reducing the difficulty of installation. At the same time, the first connecting structure provides a fulcrum for the rotation of the rotating head, allowing the rotating head to rotate accordingly, thereby achieving a folded state, thus switching between different working modes to meet different scenario requirements. For example, when the rotating head and handle are at a certain angle, it can be used as a regular hair dryer; when curling hair is required, the rotating head and handle are set coaxially, and the hair is wrapped around the surface of the rotating head to be used as a curling iron.

[0008] Preferably, the first connecting structure includes a first boss continuously arranged in a circumferential direction, a first groove is provided inside the first mounting frame, and a second groove is provided inside the second mounting frame.

[0009] The first and second grooves are circumferentially continuous and their surfaces are both fitted into the first boss. The split first and second mounting frames are respectively provided with the first and second grooves. The first and second grooves fit into the outer periphery of the first boss, allowing the rotating head to rotate with the first boss as the rotation center. This structure is simple to install and easy to implement.

[0010] Preferably, a first rubber ring is provided on the first protrusion, and the first rubber ring abuts against the surfaces of both the first and second grooves. The first protrusion is provided with a fitting groove offering a position for the first rubber ring to engage. The provision of the first rubber ring, and its abutment against the surfaces of both the first and second grooves, provides damping during rotation of the first and second grooves. This allows the rotating head to maintain its position after rotating to a certain angle, adapting to different application scenarios while avoiding limitations imposed by only a few angles that could affect user flexibility.

[0011] Preferably, with the axis of the rotating head as a reference, the first boss is inclined, and both the first and second grooves are inclined, with the inclination angles of the first and second grooves being the same as the inclination angle of the first boss. This same inclination angle allows the rotating head to rotate around the first boss, thereby adjusting the relative angle between the rotating head and the handle.

[0012] Preferably, a third groove is provided above the first boss, and one or more first limiting blocks are provided on the third groove;

[0013] The third tank is disposed within the first tank or the second tank;

[0014] The second mounting frame is provided with a second limiting block near the second groove, and the second limiting block is located above the third groove along the axial direction of the first boss;

[0015] The circumferential movement path of the second limiting block intersects with the location where the first limiting block is set. Specifically, the location of the third groove is below the upper surface of the first groove or the upper surface of the second groove; in this technical solution, the lower surface of the second limiting block contacts the upper surface of the third groove. When the second mounting frame rotates around the first boss, the second limiting block rotates circumferentially accordingly. Through the mutual abutment of the first and second limiting blocks, the rotation of the rotating head is restricted, thereby achieving the limiting effect; one or more first limiting blocks are set, and during the rotation of the second limiting block, the rotation angle of the rotating head is restricted.

[0016] Preferably, with the axis of the rotating head as a reference, the tilt angle α of the first boss is 30° to 45°.

[0017] Preferably, the rotating head further includes a first sleeve mounting structure sleeved on the outer surface of the first mounting frame and the outer surface of the second mounting frame.

[0018] Preferably, the first sleeve mounting structure includes a first sleeve sleeved on the outer surface of the first mounting frame and the outer surface of the second mounting frame, and a first mounting module connected to one end of the first mounting frame and one end of the second mounting frame.

[0019] One end of the first sleeve abuts against the first mounting module, and the ends of the first mounting frame and the second mounting frame near the first boss abut against the other end of the first sleeve. By fitting the first sleeve onto the outer surfaces of the first and second mounting frames, and simultaneously limiting the first sleeve through the abutment of the first mounting module, the first sleeve is confined to the outer surfaces of the first and second mounting frames. This mounting structure uses abutment for limiting, is simple in structure, and is easy to disassemble and install.

[0020] Preferably, the first installation module includes an air outlet block and a first abutting block connected to the air outlet block, wherein one end of the first abutting block abuts against one end of the first sleeve;

[0021] The air outlet block and the first abutment block are coaxial and arranged sequentially from the inside out. The air outlet block is connected to the first mounting frame and the second mounting frame, specifically through a snap-fit ​​structure; the first abutment block and the air outlet block are connected by screws; a gasket is provided at the connection point; the space enclosed by the air outlet block, the first abutment block, the first sleeve, the first mounting frame, and the second mounting frame all have the same central axis; this central axis has a certain angle with the axis of the first boss; the air outlet block and the first abutment block are coaxially arranged, and the first abutment block is located at the outer edge, having an abutment surface that abuts against the first sleeve, so that the air outlet block connected to the first mounting frame and the second mounting frame has an outward extending structure, thereby realizing the limiting of the first sleeve by the first mounting frame and the second mounting frame.

[0022] Preferably, a heating component is disposed within the area enclosed by the first mounting frame and the second mounting frame. Along the axial direction of the first sleeve, the heating component is positioned above the first boss, ensuring that the air outlet from the rotating head has a certain temperature.

[0023] A foldable hair dryer includes a rotating component and a handle, with a first connecting structure disposed on the handle. Along the axial direction of the handle, the first connecting structure is located at the upper end of the handle.

[0024] This application has achieved beneficial technical effects:

[0025] This utility model features a first mounting frame and a second mounting frame, which are assembled from two modules. During the installation of the rotating head and the first connecting structure, the first mounting frame and the second mounting frame are installed separately, thereby restricting the first connecting structure within the space formed by the two frames and reducing the installation difficulty. At the same time, the first connecting structure provides a fulcrum for the rotating head to rotate, allowing the rotating head to rotate accordingly and achieve a folded state. This allows for switching between different working modes to meet different scenario requirements. For example, when the rotating head and the handle are at a certain angle, it can be used as a regular hair dryer; when curling hair is needed, the rotating head and the handle are set coaxially, and the hair is wrapped around the surface of the rotating head to use it as a curling iron.

Detailed Implementation

[0034] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0035] The technical solution of this utility model will be described in detail below with specific embodiments.

[0036] Reference Figures 1 to 6 As shown, a rotating assembly includes a rotating head (1) and a first connecting structure movably connected to the rotating head (1) and providing a rotation fulcrum;

[0037] The rotating head (1) includes a first mounting frame (11) and a second mounting frame (12) connected to the first mounting frame (11) to form a continuous arrangement in the circumferential direction;

[0038] The first connecting structure is movably connected within the area enclosed by the first mounting frame 11 and the second mounting frame 12. The first connecting structure provides a fulcrum for the rotation of the rotating head and restricts its movement path; the ratio of the surface area of ​​the first mounting frame 11 to the surface area of ​​the second mounting frame 12 is 4:1 to 5:1; wherein the first mounting frame 11 and the second mounting frame 12 are connected by screws; the first mounting frame 11 and the second mounting frame 12, which are assembled from two modules, allow the rotating head 1 to be installed separately through the first mounting frame 11 and the second mounting frame 12 during the installation process, thereby restricting the first connecting structure within the space formed by the two, reducing the installation difficulty. At the same time, the first connecting structure provides a fulcrum for the rotation of the rotating head 1, allowing the rotating head 1 to rotate accordingly, thereby achieving a folded state, thus switching between different working modes to meet different scenario requirements. For example, when the rotating head 1 and the handle are at a certain angle, it can be used as a regular hair dryer; when curling hair is required, the rotating head 1 and the handle are set coaxially, and the hair is wrapped around the surface of the rotating head 1 to be used as a curling iron.

[0039] The first connecting structure includes a first boss 13 continuously arranged in a circumferential direction, a first groove 111 is provided inside the first mounting frame 11, and a second groove 121 is provided inside the second mounting frame 12.

[0040] The first groove 111 and the second groove 121 are circumferentially continuous and their surfaces are fitted into the first boss 13. The split first mounting frame 11 and the second mounting frame 12 are respectively provided with the first groove 111 and the second groove 121. The first groove 111 and the second groove 121 fit into the outer periphery of the first boss 13, so that the rotating head 1 can rotate with the first boss 13 as the rotation center. This structure is simple to install and easy to implement.

[0041] A first rubber ring 131 is provided on the first boss 13, and the first rubber ring 131 abuts against the surfaces of the first groove 111 and the second groove 121. The first boss 13 is provided with a fitting groove 132 that provides a fitting position for the first rubber ring 131. The first rubber ring 131 abuts against the surfaces of the first groove 111 and the second groove 121, providing a certain degree of damping during rotation of the first groove 111 and the second groove 121. This allows the rotating head 1 to maintain its position after rotating to a certain angle as needed, adapting to different application scenarios and avoiding limitations on the user's flexibility due to only a few angles being a constraint.

[0042] With the axis of the rotating head 1 as a reference, the first boss 13 is inclined, and both the first groove 111 and the second groove 121 are inclined. The inclination angles of the first groove 111 and the second groove 121 are the same as the inclination angle of the first boss 13. The same inclination angle allows the rotating head 1 to rotate around the first boss 13, thereby allowing the relative angle between the rotating head 1 and the handle to be adjusted.

[0043] A third groove 133 is provided above the first boss 13, and one or more first limiting blocks 134 are provided on the third groove 133;

[0044] The third groove 133 is disposed within the first groove 111 or the second groove 121;

[0045] The second mounting frame 12 is provided with a second limiting block 122 near the second groove 121, and the second limiting block 122 is provided above the third groove 133 along the axial direction of the first boss 13.

[0046] The circumferential movement path of the second limiting block 122 intersects with the location of the first limiting block 134. Specifically, the third groove 133 is located below the upper surface of the first groove 111 or the upper surface of the second groove 121; in this technical solution, the lower surface of the second limiting block 122 contacts the upper surface of the third groove 133. When the second mounting frame 12 rotates around the first boss 13, the second limiting block 122 rotates circumferentially accordingly. Through the mutual abutment between the first limiting block 134 and the second limiting block 122, the rotation of the rotating head 1 is restricted, thereby achieving the limiting effect; one or more first limiting blocks 134 are set, and in conjunction with the rotation of the second limiting block 122, the rotation angle of the rotating head 1 is restricted.

[0047] With the axis of the rotating head 1 as a reference, the tilt angle α of the first boss 13 is 30° to 45°.

[0048] The rotating head 1 also includes a first sleeve mounting structure that is sleeved on the outer surface of the first mounting frame 11 and the outer surface of the second mounting frame 12.

[0049] The first sleeve mounting structure includes a first sleeve 141 sleeved on the outer surface of the first mounting frame 11 and the outer surface of the second mounting frame 12, and a first mounting module 142 connected to one end of the first mounting frame 11 and one end of the second mounting frame 12.

[0050] One end of the first sleeve 141 abuts against the first mounting module 142. The ends of the first mounting frame 11 and the second mounting frame 12 near the first protrusion 13 also abut against the other ends of the first sleeve 141. By fitting the first sleeve 141 onto the outer surfaces of the first mounting frame 11 and the second mounting frame 12, and by using the first mounting module 142 to abut and limit the first sleeve 141, the first sleeve 141 is confined to the outer surfaces of the first mounting frame 11 and the second mounting frame 12. This mounting structure uses abutment for limiting, is simple in structure, and is easy to disassemble and install.

[0051] The first installation module 142 includes an air outlet block 143 and a first abutting block 144 connected to the air outlet block 143, one end of the first abutting block 144 abutting against one end of the first sleeve 141;

[0052] The air outlet block 143 and the first contact block 144 are coaxial and arranged sequentially from the inside out. The air outlet block 143 is connected to the first mounting frame 11 and the second mounting frame 12, specifically through a snap-fit ​​structure; the first contact block 144 and the air outlet block 143 are connected by screws; a gasket is provided at the connection point; the space enclosed by the air outlet block 143, the first contact block 144, the first sleeve 141, the first mounting frame 11, and the second mounting frame 12 all have the same central axis; this central axis has a certain angle with the axis of the first boss 13; wherein the air outlet block 143... 3. Multiple fitting posts 145 are provided. Multiple fitting holes 146 are provided inside the first sleeve 141 to fit into the fitting posts 145 and restrict their rotation. The air outlet block 143 is coaxially arranged with the first abutting block 144, and the first abutting block 144 is arranged on the outer edge and has an abutting surface that abuts against the first sleeve 141. This makes the air outlet block 143 connected to the first mounting frame 11 and the second mounting frame 12 have an outwardly extending structure, thereby realizing the limiting of the first sleeve 141 by the first mounting frame 11 and the second mounting frame 12.

[0053] A heating assembly 15 is disposed within the area enclosed by the first mounting frame 11 and the second mounting frame 12. The heating assembly is positioned above the first boss along the axial direction of the first sleeve, ensuring that the air outlet from the rotating head has a certain temperature.
