Description

Technical Field

[0001] The invention belongs to the technical field of hair dryers, and in particular relates to a rotary hair dryer. Background Art

[0002] A hair dryer is a device that absorbs air, heats the air, and outputs it to the outside. It is used to dry wet hair in daily life. In the prior art, hair dryers with a rotating structure have a rotatable rotating head, which is mostly achieved by a hinge structure. However, this structure is cumbersome to install and disassemble. Moreover, due to the lack of a corresponding damping structure during the rotation process, it can only achieve a small number of specific angles of rotation. Among the rotating heads with a multi-layer structure, its installation structure is relatively complex and inconvenient to install and disassemble. In addition, the handles in the prior art are connected by gluing or screwing, but this fixing method is not conducive to subsequent disassembly and maintenance. At the same time, there is only an air inlet without a corresponding filtering structure, which will inhale a lot of dust and affect the operation of the internal electrical components.

[0003] At the same time, during daily use, the hair dryer needs to be constantly rotated and the angle needs to be changed, so the power cord that provides electricity will be constantly bent during operation. Therefore, an adapter with a rotating effect is produced. The adapter allows the power cord to rotate freely during operation, thereby reducing the degree of bending; however, the fixing method of the adapter in the prior art is relatively complicated, which is not conducive to assembly operations during the production process. In order to solve at least one of the above technical problems, it is necessary to develop a rotary hair dryer. Summary of the Invention

[0004] The object of the present invention is to provide a rotary hair dryer to solve the above technical problems. The first mounting frame and the second mounting frame formed by the two modules are installed so that during the installation process of the rotating head and the first connecting structure, the first mounting frame and the second mounting frame are installed separately, thereby limiting 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 rotating head to rotate accordingly, so that the rotating head can rotate accordingly to achieve a folded state, thereby being able to switch to different working modes to meet different scene requirements.

[0005] An air intake module is provided, and a first air filter assembly is provided in the air intake module, and is connected to the handle body through the air intake module, so as to limit the first air filter assembly and prevent the first air filter assembly from falling out to the outside. This connection method is simple. When disassembly is required later, only the connection state between the air intake module and the handle body needs to be released to release the limiting state of the first air filter assembly, which is convenient for disassembly and maintenance; the first air filter assembly is provided to facilitate blocking external dust.

DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0051] The technical solution of the present invention is described in detail below with reference to specific embodiments.

[0052] Reference Figures 1 to 15 As shown, a rotary hair dryer includes a rotating assembly and a handle;

[0053] The rotating assembly comprises a rotating head (1), and a first connecting structure movably connected to the rotating head (1) and providing a rotating fulcrum;

[0054] The rotary head (1) comprises a first mounting frame (11) and a second mounting frame (12) connected to the first mounting frame (11) to form a circumferentially continuous arrangement;

[0055] 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 rotating head during rotation and limits 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. 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 are assembled into two modules. During the installation of the rotating head 1 and the first connecting structure, the first mounting frame 11 and the second mounting frame 12 are installed separately, thereby confining the first connecting structure to the space formed by the first mounting frame 11 and the second mounting frame 12, reducing the installation difficulty. At the same time, the first connecting structure provides a fulcrum for the rotating head 1 to rotate accordingly, thereby achieving a foldable state, thereby switching to different working modes to meet different scene requirements. For example, when the rotating head 1 and the handle are at a certain angle, it can be used as a conventional hair dryer. When curling hair, the rotating head 1 and the handle are coaxially arranged, and hair is wrapped around the surface of the rotating head 1 to use it as a curling iron.

[0056] The first connection structure includes a first boss 13 continuously arranged in a circumferential direction, a first slot 111 is arranged inside the first installation frame 11, and a second slot 121 is arranged inside the second installation frame 12.

[0057] The first and second grooves 111, 121 are circumferentially continuous and their surfaces engage with the first boss 13. The split first and second mounting frames 11, 12 are provided with the first and second grooves 111, 121, respectively. The first and second grooves 111, 121 engage with the outer circumference of the first boss 13, allowing the rotary head 1 to rotate around the first boss 13. This structure is simple to install and easy to implement.

[0058] A first rubber ring 131 is provided on the first boss 13, and the first rubber ring 131 contacts the surfaces of both the first slot 111 and the second slot 121. The first boss 13 is provided with a fitting slot 132 that provides a fitting position for the first rubber ring 131. The first rubber ring 131 is provided so as to contact the surfaces of both the first slot 111 and the second slot 121, thereby providing a certain degree of damping during the rotation of the first and second slots 111 and 121. This allows the rotating head 1 to maintain its position after rotating to a certain angle as needed, thereby adapting to different application scenarios at different angles while avoiding the impact of limited angles that would affect the user's flexibility.

[0059] With the axis of the rotating head 1 as a reference, the first boss 13 is tilted, and the first and second slots 111 and 121 are also tilted. The tilt angles of the first and second slots 111 and 121 are the same as the tilt angle of the first boss 13. This same tilt angle allows the rotating head 1 to rotate about the first boss 13, thereby adjusting the relative angle between the rotating head 1 and the handle.

[0060] 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 ;

[0061] The third tank body 133 is disposed in the first tank body 111 or the second tank body 121;

[0062] The second mounting frame 12 is provided with a second limiting block 122 near the second slot 121 . Along the axial direction of the first boss 13 , the second limiting block 122 is provided above the third slot 134 .

[0063] The circumferential movement path of the second limit block 122 intersects with the location where the first limit block 133 is set. Specifically, the upper surface of the first trough body 111 or the lower part of the upper surface of the second trough body 121 is where the third trough body 133 is set; in this technical solution, the lower surface of the second limit block 122 contacts the upper surface of the third trough body 133. When the second mounting frame 12 rotates around the first boss 13, the second limit block 122 rotates circumferentially accordingly, and the first limit block 134 and the second limit block 122 interfere with each other, thereby limiting the rotation of the rotating head 1 to achieve a limiting effect; one or more first limit blocks 134 are set, and in the process of cooperating with the second limit block 122 to rotate, the rotation angle of the rotating head 1 is limited.

[0064] With the axis of the rotary head 1 as a reference, the inclination angle α of the first boss 13 is 30° to 45°.

[0065] The rotary head 1 further includes a first sleeve mounting structure sleeved on the outer surface of the first mounting frame 11 and the outer surface of the second mounting frame 13 .

[0066] 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;

[0067] One end of the first sleeve 141 abuts against the first mounting module 142, and the end of the first mounting frame 11 proximal to the first boss 13 and the end of the second mounting frame 12 proximal to the first boss 13 both abut against the other end of the first sleeve 141. The first sleeve 141 is sleeved onto the exteriors of the first and second mounting frames 11, 12, and the first mounting module 142 abuts against and limits the first sleeve 141, thereby restricting it to the exteriors of the first and second mounting frames 11, 12. This mounting structure, which utilizes a conflict-based position limiter, is simple in structure and easy to disassemble and install.

[0068] The first installation module 142 includes an air outlet block 143 and a first interference block 144 connected to the air outlet block 143 , wherein one end of the first interference block 144 interferes with one end of the first sleeve 141 ;

[0069] The air outlet block 143 and the first interference block 144 are coaxial and arranged in sequence from the inside to the outside. The air outlet block 143 is connected to the first mounting frame 11, and the air outlet block 143 is connected to the second mounting frame 12, specifically through a snap-fit structure; wherein the first interference block 144 and the air outlet block 143 are connected by screws; a gasket is set at the connection; the space enclosed by the air outlet block 143, the first interference block 144, the first sleeve 141, the first mounting frame 11 and the second mounting frame 12 all have the same central axis; the central axis has a certain angle with the axis of the first boss 13; wherein the air outlet block 14 A plurality of interlocking columns 145 are provided, and a plurality of interlocking holes 146 are provided inside the first sleeve 141, which interlock with the interlocking columns 145 to limit its rotation. The air outlet block 143 and the first interference block 144 are coaxially arranged, and the first interference block 144 is provided on the outer edge and has an interference surface for interfering with the first sleeve 141. The air outlet block 143 connected to the first mounting frame 11 and the second mounting frame 12 has an outwardly extending structure, thereby realizing the first mounting frame 11 and the second mounting frame 12 to limit the first sleeve 141.

[0070] 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 disposed above the first boss along the axial direction of the first sleeve, so that the air outlet from the rotating head has a certain temperature.

[0071] Along the axial direction of the handle 2 , the first connection structure is connected to the upper end of the handle body 12 .

[0072] The handle includes a handle body 21, a first air filter assembly 22, and an air inlet module 23 connected to the handle body 21 to limit the first air filter assembly 22. The first air filter assembly 22 is disposed inside the air inlet module 23. One end of the first air filter assembly 22 contacts the handle body 21, and the air inlet module 23 is disposed therein. The first air filter assembly 22 is disposed within the air inlet module 23 and is connected to the handle body 21 by the air inlet module 23, thereby limiting the first air filter assembly 22 and preventing it from falling out. This connection method is simple. When disassembly is required later, the first air filter assembly 22 can be released from its limited state by simply releasing the connection between the air inlet module 23 and the handle body 21, thereby facilitating disassembly and maintenance. The first air filter assembly 22 is provided to block external dust.

[0073] The first air filter assembly 22 and the air inlet module 23 are coaxially arranged; the first air filter assembly 22 and the handle body 21 have the same axis. The first air filter assembly 22 is sleeved inside the air inlet module 23, and the air inlet module 23 is connected to the coaxially arranged handle body 21 to complete the position control of the first air filter assembly 22. This connection method is simple and easy to install or remove.

[0074] The handle body 21 includes an outer shell 211;

[0075] Along the axial direction of the handle body 211, one end of the first air filter assembly 22 contacts one end of the outer shell 211, and the other end of the first air filter assembly 22 contacts the inner surface of the air inlet module 23. This contact between the outer shell 211 and the inner surface of the air inlet module 23 at both ends of the first air filter assembly 22 improves structural stability after installation.

[0076] The air inlet module 23 includes a connecting frame 231 and a first connecting block 232 partially disposed inside the connecting frame 231. The other end of the first air filter assembly 22 contacts the bottom of the inner surface of the connecting frame 231.

[0077] The handle body 21 also includes a connecting member 212 disposed within the outer shell 211. The connecting member 212 includes a first connecting groove 213 connected to a first connecting block 232. There is a certain distance between the end of the connecting member 212 where the first connecting groove 213 is located and the end of the outer shell 211. The end of the connecting frame 231, away from the first connecting block 232, contacts the outer shell 211. Along the radial direction of the outer shell 211, the connecting member 212, the first air filter assembly 22, and the connecting frame 231 are coaxially arranged in order from the inside out. The connecting frame 231 is provided with a first connecting block 232, and the first connecting block 232 is limited in the first connecting groove 213 in a spiral manner, thereby connecting the air intake module 23 and the handle body 21, so that the first air filter assembly 22 is limited between the connecting frame 231 and the outer shell 211. The installation and disassembly method is simple, and it is only necessary to rotate the connecting member 212 to adjust the connection state of the first connecting block 232 and the first connecting groove 213.

[0078] The first connection blocks 232 and the first connection slots 213 are arranged in groups, one group or multiple groups.

[0079] Along the axial direction of the air inlet module 23, the first connecting block 232 is disposed near the bottom of the connecting frame 231. A certain distance is maintained between the first connecting block 232 and the end surface of the connecting frame 231. Furthermore, the connecting frame 231 has space for accommodating the first air filter assembly 22 outside the location of the first connecting block 232. The connecting frame 231 is connected near the bottom, and the upper end of the connecting frame 231 contacts the outer shell 211, thereby accommodating a length that matches the first air filter assembly 22.

[0080] The connecting frame 231 is provided with an air inlet 233. The air inlet 233 is provided on the radial surface of the connecting frame 231; the first filter is provided radially toward the air inlet 233;

[0081] The first air filter assembly 22 includes a support frame 221 and a first filter screen 222 disposed on a radial surface of the support frame 221;

[0082] Along the axial direction of the outer shell 211, one end of the support frame 221 contacts the outer shell 211, and the other end of the support frame 221 contacts the bottom of the inner surface of the connecting frame 231. The first filter 222 is mounted on the support frame 221, providing a load-bearing structure for the first filter 222 to maintain its shape. The upper and lower ends of the support frame 221 serve as contact points, facilitating the positioning of the first filter 222.

[0083] The connecting member 212 is provided with a resisting piece 214 , and the resisting piece 213 is provided along the axial direction of the outer shell 211 toward the first connecting block 232 ;

[0084] Along the radial direction of the outer shell 211, one side of the first connection block 232 contacts one side of the support frame 221, and the other side of the support frame 221 contacts the inner surface of the connection frame 231. The support frame 221 has multiple contact surfaces, which improves the connection stability of the support frame 221.

[0085] The support frame 221 is connected to the connecting member 212 by screws near the first connecting block 232, and is specifically connected to the connecting member 212 near the location of the first connecting slot 213;

[0086] A second air filter assembly is further disposed inside the outer shell 211 , wherein the second air filter assembly includes a second filter screen 215 , and the extension of the filter surface of the first filter screen 222 and the extension of the filter surface of the second filter screen 215 are disposed perpendicular to each other.

[0087] The handle includes a handle body, which includes a connecting member 212 and an adapter assembly 3 that is embedded within the connecting member 212 to prevent axial or radial movement. The adapter assembly 3 is installed within the connecting member 212 by embedding, thereby being restrained by the connecting member 212 to prevent it from falling out or shaking. This embedded installation reduces the assembly difficulty during the production process. During subsequent disassembly, only the embedded state of the adapter assembly 3 within the connecting member 212 needs to be released, making the disassembly process simple and convenient.

[0088] The connecting member 212 includes a first member 216 and a second member 217 that are arranged in pairs and connected to each other to form an internal closure. The adapter assembly 3 is embedded between the first member 216 and the second member 217. The first member 216 and the second member 217 can be connected and fixed by screws or buckles. The present technical solution adopts screw fixation. The first member 216 and the second member 217 are connected after being aligned with each other. The adapter assembly 3 is embedded in the range enclosed by the first member 216 and the second member 217. Since multiple modules are assembled, the installation process is through alignment and fixation, which reduces the installation difficulty. When disassembly and installation are required, the connection between the first member 216 and the second member 217 is released, and the adapter assembly 3 can be released from the embedded state.

[0089] A first receiving groove 2161 for receiving one side of the adapter assembly 3 is provided inside the first component 216; a second receiving groove 2171 for receiving the other side of the adapter assembly 3 is provided inside the second component 217;

[0090] The first receiving groove 2161 and the second receiving groove 2171 are arranged radially opposite to each other along the handle body 21. The shape enclosed by the first receiving groove 2161 and the second receiving groove 2171 is adapted to the outer shape of the adapter body 3. During the installation process, the first receiving groove 2161 and the second receiving groove 2171 are arranged inside. After the second member 217 and the first member 216 are attached to each other and fixedly connected, since the first receiving groove 2161 and the second receiving groove 2171 are arranged relative to each other, the second receiving groove 2171 is correspondingly engaged with the other side of the adapter assembly 3. No other fasteners are required for connection, which reduces the difficulty of assembly. Disassembly releases the connection between the first member 216 and the second member 217, and the adapter assembly 3 can be removed from the first receiving groove 2161 or the second receiving groove 2171, making the disassembly process simple.

[0091] The adapter assembly 3 includes an adapter body 30 , a first terminal 31 and a second terminal 32 disposed on the adapter body 30 ;

[0092] The adapter body 30 is embedded in the space enclosed by the first receiving groove 2161 and the second receiving groove 2171. A first terminal 31 and a second terminal 32 are provided at different heights to facilitate contact with the power supply assembly for power supply. The effective contact surfaces of the first terminal 31 and the second terminal 32 are both arc-shaped, and the effective contact end of the power supply assembly is cylindrical and can rotate during the operation of the hair dryer. A first mating plane 300 is provided on both sides of one end of the adapter body 30. A second mating plane 2160 is provided inside the first component 216 above the first receiving groove 216 to mate with the first mating plane 300. A third mating plane 2170 is provided inside the second component 217 above the second receiving groove 2171 to mate with the first mating plane 399. Since the first mating plane 300, the second mating plane 2160, and the third mating plane 2170 are all in a planar mating state, the adapter body 30 can be effectively prevented from rotating in this state.

[0093] The adapter body 30 is provided with a first mounting frame 33 for mounting the first terminal 31 , a second mounting frame 34 for mounting the second terminal 32 , and a connecting hole 35 connecting the first mounting frame 33 and the second mounting frame 34 .

[0094] The first mounting frame 33 and the second mounting frame 34 are arranged at different levels along the axial direction of the adapter body 30, so that the first terminal 31 and the second terminal 32 have different operating planes; the connecting hole 35 connects the first mounting frame 33 and the second mounting frame 34 along the axial direction of the handle body, providing space for the power supply component to pass through.

[0095] The first mounting frame 33 is provided with a first fixing post 36 that matches the first terminal 31 and a first limiting post 37 that prevents the first terminal 31 from shaking during operation;

[0096] The second mounting frame 34 is provided with a second fixing post 38 that cooperates with the second terminal 32, and a second limiting post 39 that prevents the second terminal 31 from shaking during operation. This improves the fixing stability of the first and second terminals 31, 32, and prevents shaking during operation. The inner surface of the first terminal 31 is arranged toward the first limiting post 37, and the inner surface of the second terminal 32 is arranged toward the second limiting post 39. In this technical solution, the first limiting post 37 and the second limiting post 39 are both cubes or rectangular parallelepipeds.

[0097] Along the axial direction of the handle body, the projection of the first limiting post 37 does not overlap with the projection of the second limiting post 39, and the projection of the first fixing post 36 does not overlap with the projection of the second fixing post 39. This avoids overlap between the connection points of the first and second terminals, maintains a certain distance, and improves safety.

[0098] The connecting member 212 is connected to the power supply assembly 4, which extends through the adapter body 30 and contacts the first terminal 31 and the second terminal 32. The power supply assembly 4 is disposed between the first member 216 and the second member 217. The power supply assembly extends through the space enclosed by the first member 216 and the second member 217 and extends through the adapter assembly 3. During operation, the power supply assembly 4 can rotate relative to the first member 216 or the second member 217, but the rotating power supply assembly 4 maintains contact with the first terminal 31 and the second terminal 32, thereby not affecting the operation of the hair dryer.

[0099] The first member 216 is provided with a third receiving groove 2162 that mates with one side of the power supply assembly 4. The second member 217 is provided with a fourth receiving groove 2172 that mates with the other side of the power supply assembly 4. The third and fourth receiving grooves 2162, 2172 are radially opposite each other along the handle body. The third and fourth receiving grooves 2162, 2172 are arranged circumferentially and continuously, forming a ring-shaped enclosure. This prevents axial movement of the power supply assembly 4 relative to the connecting member, improving connection and operational stability. The power supply assembly rotates within the space enclosed by the third and fourth receiving grooves 2162, 2172.

[0100] The adapter body 30 is coaxially arranged with the power supply assembly 4;

[0101] The first connection structure is connected to the upper end of the first component (216); the first connection groove (213) is arranged on the first component (216) and the second component (216).
