[0038] The invention provides a hair dryer.

[0039] In the embodiments of the present invention, please refer to Figures 1 to 12 The hair dryer includes a barrel 10 and a handle 20. The barrel 10 is provided with an air outlet 101 and an air supply duct 103 connected to the air outlet 101. The air outlet 101 is located at one end of the barrel 10. The air supply duct 103 is provided with an air supply assembly 14. The barrel 10 can be provided with an air inlet, with the air supply duct 103 located between the air inlet and the air outlet 101. Alternatively, the handle 20 can be provided with an air inlet, with the air supply duct 103 located partially within the handle 20 and partially within the barrel 10. In this case, the air supply assembly 14 can be located either within the barrel 10 or within the handle 20. Optionally, the hair dryer further includes a power cord (not shown), which is installed in the barrel 10 or the handle 20 and is electrically connected to the air supply assembly 14.

[0040] In some embodiments, a rotating structure 11 is provided on the barrel 10 at one end away from the air outlet 101; a handle 20 is rotatably mounted on the rotating structure 11, and the rotation axis of the handle 20 is tilted relative to the axis of the barrel 10. The handle 20 has a use state and a storage state. When the handle 20 is rotated relative to the barrel 10 to the use state, the handle 20 and the barrel 10 are arranged at an angle. When the handle 20 is rotated relative to the barrel 10 to the storage state, the handle 20 extends along the axis of the barrel 10 to form a straight tube structure with the barrel 10. Specifically, when in use, the handle 20 and the barrel 10 are arranged at an angle, that is, the angle between the handle 20 and the barrel 10 is greater than 0° and less than 180°. The angle between the handle 20 and the barrel 10 can be an acute angle or an obtuse angle close to 90°, or it can be a right angle. When in the storage state, the angle between the handle 20 and the barrel 10 is approximately 180°, so that the hair dryer is straight tube-shaped as a whole.

[0041] The technical solution of the present invention is to provide a rotating structure 11 on the end of the barrel 10 away from the air outlet 101, and to rotatably mount the handle 20 on the rotating structure 11. The rotation axis of the handle 20 is inclined relative to the axis of the barrel 10. When the handle 20 is rotated relative to the barrel 10 to the use state, the handle 20 and the barrel 10 are arranged at an angle, thereby making it convenient for the user to hold the handle 20 and use the hair dryer to blow dry their hair. After use, when it is necessary to store the hair dryer, the handle 20 can be rotated relative to the barrel 10 to the storage state, so that the handle 20 extends along the axis of the barrel 10 to form a straight cylindrical structure with the barrel 10. In this way, the size of the hair dryer in a direction perpendicular to the axis of the barrel 10 can be reduced in the storage state, thereby reducing the space occupied by the hair dryer when stored (i.e., the storage space). This makes it convenient to carry and use when traveling, and also convenient to store at home, thereby improving the convenience of use. Moreover, when the hair dryer is in the storage state, the hair dryer can also be used by holding the handle 20. For example, when holding the handle 20 to dry low objects such as wet floors, bending over can be reduced or avoided, thereby increasing the application scenarios of the hair dryer.

[0042] In some embodiments, the rotating structure 11 is provided with a first anti-rotation portion 112, and the handle 20 is provided with a second anti-rotation portion 211. The first anti-rotation portion 112 is located in the movement path of the second anti-rotation portion 211 when the handle 20 rotates. The first anti-rotation portion 112 and the second anti-rotation portion 211 prevent the handle 20 from rotating 360° relative to the barrel 10. Optionally, the handle 20 is provided with two second anti-rotation portions 211, respectively located on opposite sides of the rotating structure 11. When in use, one side of the first anti-rotation portion 112 abuts against one of the second anti-rotation portions 211, and when in storage, the other side of the first anti-rotation portion 112 abuts against the other second anti-rotation portion 211, so that the handle 20 does not rotate more than 180° relative to the barrel 10. In this way, when buttons and a power cord are provided on the handle 20, damage to the wiring between the barrel 10 and the handle 20 is avoided.

[0043] In some embodiments, the rotating structure 11 is provided with a first through-hole 113 and an annular portion 114 disposed around the first through-hole 113. The first through-hole 113 is connected to the air supply duct 103. The handle 20 is rotatably mounted on the annular portion 114. The handle 20 is provided with an air duct cavity 201 and a first air inlet 202. The air duct cavity 201 is connected to the first air inlet 202 and the first through-hole 113. Specifically, the first air inlet 202 is located outside the gripping area of ​​the handle 20, and the rotation axis of the handle 20 passes through the first through-hole 113. Using the handle 20 to provide the air inlet can reduce the length of the body 10, thereby reducing the size of the hair dryer. Furthermore, by rotatably mounting the handle 20 on the annular portion 114, and providing the first through-hole 113 on the inner side of the annular portion 114 to connect the air duct cavity 201 and the air supply duct 103, the air duct cavity 201 can be connected to the air supply duct 103 regardless of whether the hair dryer is stored or in use, thereby enabling normal operation of the hair dryer in both the stored and used states. Of course, in other embodiments, the air inlet may also be provided on the side of the barrel body 10 .

[0044] In some embodiments, the handle 20 is rotatably mounted on the outer periphery of the annular portion 114. The handle 20 is provided with an elastic limiting ring 23, which is rotatably mounted within the first through-hole 113. One of the inner wall of the first through-hole 113 and the outer circumferential surface of the elastic limiting ring 23 is provided with at least one limiting protrusion 231, and the other is provided with at least two limiting grooves 115. The two limiting grooves 115 are spaced apart in the circumferential direction of the elastic limiting ring 23. In the use state, the limiting protrusion 231 is engaged with one of the limiting grooves 115, and in the storage state, the limiting protrusion 231 is engaged with the other limiting groove 115. In this embodiment, the inner wall of the first through-hole 113 is provided with at least two limiting grooves 115, and the outer circumferential surface of the elastic limiting ring 23 is provided with at least one limiting protrusion 231.

[0045] Specifically, the edge of the limiting slot 115 is configured in an arc-shaped transition, and the limiting protrusion 231 is configured in a roughly spherical shape. The elastic limiting ring 23 is capable of elastically deforming inward. When the limiting protrusion 231 is offset from the limiting slot 115 and abuts the inner wall of the first through-hole 113, the elastic limiting ring 23 is compressed and deformed. When the handle 20 is rotated until the limiting protrusion 231 moves into the limiting slot 115, the elastic limiting ring 23 acts to cause the limiting protrusion 231 to engage within the limiting slot 115. If the limiting protrusion 231 is stuck in the limiting slot 115, rotating the handle 20 requires overcoming the friction between the limiting protrusion 231 and the annular portion 114, as well as the elastic force of the elastic limiting ring 23, to allow the limiting protrusion 231 to be removed from the limiting slot 115. This can prevent the barrel body 10 from automatically rotating relative to the handle 20 under the action of gravity during use, so that the handle 20 is stable in the use state and the storage state, which is more convenient for users to use.

[0046] Of course, in other embodiments, the limiting protrusion 231 and the limiting groove 115 may not be provided. By reducing the gap between the elastic limiting ring 23 and the inner wall of the first through hole 113, the friction between the elastic limiting ring 23 and the inner wall of the first through hole 113 is increased to prevent the barrel 10 and the handle 20 from automatically rotating. In addition, in other embodiments, the handle 20 is provided with a rotating structure, the rotating structure is provided with a ventilation hole, the rotating structure is rotatably installed in the first through hole 113, and the ventilation hole is connected to the air supply duct 103 and the air duct cavity 201.

[0047] In some embodiments, the elastic limiting ring 23 is detachably mounted on the handle 20 to facilitate replacement when the elastic limiting ring 23 is damaged.

[0048] In some embodiments, there are two limiting protrusions 231, each located on opposite sides of the elastic limiting ring 23. At least two limiting slots 115 are also located on opposite sides of the elastic limiting ring 23. In both the in-use and stored states, each limiting protrusion 231 engages with a corresponding limiting slot 115. Specifically, the line connecting the two limiting protrusions 231 substantially passes through the rotation axis of the handle 20. When the number of limiting slots 115 is greater than two, the line connecting at least two limiting slots 115 substantially passes through the rotation axis of the handle 20. When the handle 20 is in use, each limiting protrusion 231 engages with a corresponding limiting slot 115. When the handle 20 is rotated 180° relative to the barrel 10 and stored, each limiting protrusion 231 also engages with a corresponding limiting slot 115. This increases the contact area between the elastic limiting ring 23 and the annular portion 114, further improving the stability of the handle 20 when in use and in the stored state. Furthermore, the elastic limiting ring 23 can be subjected to uniform force on both sides, thereby reducing the wear of the elastic limiting ring 23 caused by uneven force, and extending the service life of the elastic limiting ring 23. Of course, in other embodiments, only one limiting protrusion 231 and two limiting grooves 115 may be provided. In this case, the two limiting grooves 115 may be provided on opposite sides of the elastic limiting ring 23, and the angle between the two limiting grooves 115 and the perpendicular to the rotation axis may be less than 180°.

[0049] In some embodiments, there are six limiting slots 115, which are evenly spaced along the circumference of the elastic limiting ring 23. Specifically, the six limiting slots 115 are grouped together, with two limiting slots 115 in each group located on opposite sides of the elastic limiting ring 23. Whenever the handle 20 is rotated 60° relative to the barrel 10, it remains stably in this position. This allows for a variety of usage states, allowing the user to adjust the angle between the handle 20 and the barrel 10 according to actual usage, making it more convenient for the user.

[0050] In some embodiments, the outer circumference of the annular portion 114 is provided with an annular retaining groove 116, and the handle 20 is provided with an annular retaining protrusion 25. The handle 20 is rotatably mounted on the outer surface of the annular portion 114, and the annular retaining protrusion 25 is located within the annular retaining groove 116. Specifically, the handle 20 includes two shells, which are assembled to form the air duct cavity 201 and the annular retaining protrusion 25. That is, the joint between the two shells extends along the length of the handle 20. The annular retaining protrusion 25 is located at the end of the handle 20, and the annular portion 114 is rotatably mounted on the inner hole of the annular retaining protrusion 25, while the annular retaining protrusion 25 is located within the annular retaining groove 116. This simple structure can simplify the structure of the hair dryer. In other embodiments, the outer circumference of the annular portion 114 is provided with an annular protrusion, and the end of the handle 20 is provided with an opening connected to the air duct cavity 201. The opening is provided with an annular groove. The handle 20 is mounted on the annular portion 114 through the opening, and the annular protrusion is located within the annular groove.

[0051] In some embodiments, the barrel 10 includes a shell 12, one end of the shell 12 is provided with an air outlet 101, and the other end is provided with a mounting port 121. The rotating structure 11 includes a mounting cylinder 111, which is detachably mounted in the shell 12, and the mounting cylinder 111 is provided with an annular portion 114 at the mounting port 121. Specifically, the mounting port 121 is open, and the mounting cylinder 111 is through-set at both ends. The mounting cylinder 111 is installed in the shell 12 through the mounting port 121. In this way, when the annular portion 114 is damaged, it can be repaired by replacing the mounting cylinder 111, which can reduce maintenance costs. In addition, the shell 12 and the rotating structure 11 are separated and molded, which can simplify the structure of the shell 12 and reduce the production cost of the hair dryer. Of course, in other embodiments, the rotating structure 11 and the shell 12 are integrally molded.

[0052] In some embodiments, a first clamping portion 117 is provided on the outer side of the mounting tube 111, a second clamping portion 122 is provided in the inner wall of the housing 12, the first clamping portion 117 and the second clamping portion 122 are clamped together, the housing 12 is provided with a second through hole 124, a screw hole 118 is provided at a position of the mounting tube 111 corresponding to the second through hole 124, and the barrel body 10 further includes a screw, which passes through the second through hole 124 and is screwed into the screw hole 118. In this way, during installation, the mounting tube 111 can be first installed into the housing 12, and the first clamping portion 117 and the second clamping portion 122 are clamped together to achieve preliminary fixation of the mounting tube 111, and then the housing 12 and the mounting tube 111 are fixed by the screw. In this way, after the mounting tube 111 is initially fixed by the clamping of the first clamping portion 117 and the second clamping portion 122, it is convenient to subsequently install the screw into the screw hole 118, making assembly convenient. Fixing the housing 12 and the mounting tube 111 with screws after the clamping can ensure a stable installation of the mounting tube 111 and reduce the risk of the mounting tube 111 becoming loose during use.

[0053] An internal thread can be pre-formed in the screw hole 118, or a hole can be pre-formed in the mounting tube 111. When a screw is screwed into the hole, an internal thread is formed on the inner wall of the hole, thereby forming the screw hole 118 in the mounting tube 111 (i.e., the screw can be a self-tapping screw). In addition, both the first clamping portion 117 and the second clamping portion 122 can be configured as a convex structure, or one of the first clamping portion 117 and the second clamping portion 122 can be configured as a convex structure and the other as a slot 31 structure.

[0054] In some embodiments, the mounting opening 121 is provided with a fixing portion 123, which is provided with a second through hole 124. The barrel 10 further includes a decorative ring 13, which is sleeved on the fixing portion 123 and covers the second through hole 124. In this arrangement, the decorative ring 13 can cover the second through hole 124, preventing the screw from being exposed, thereby improving the appearance.

[0055] In some embodiments, the end of the barrel 10 is provided with a first inclined surface 104, the rotating structure 11 is located at the first inclined surface 104, and the end of the handle 20 is provided with a second inclined surface 203 parallel to the first inclined surface 104, and the rotation axis of the handle 20 is perpendicular to the first inclined surface 104 and the second inclined surface 203. That is, the first inclined surface 104 is the end surface of the barrel 10, and the second inclined surface 203 is the end surface of the handle 20. The first inclined surface 104 and the second inclined surface 203 are arranged relative to each other, so that the gap between the handle 20 and the barrel 10 is small, thereby reducing the risk of foreign matter such as dust entering the rotating structure 11. Of course, in other embodiments, the end surface of the barrel 10 is perpendicular to its axis, and the end surface of the handle 20 is perpendicular to its outer circumference.

[0056] In some embodiments, the handle 20 includes a connecting portion 21 and two extension portions 22, the connecting portion 21 is connected to the barrel 10, the two extension portions 22 are arranged at intervals on the connecting portion 21, and both extend in a direction away from the barrel 10, a winding space 204 is formed between the two extension portions 22, and the winding space 204 forms a winding opening 205 at the end portions of the two extension portions 22 (the end portions of the extension portions 22, i.e., the end portions of the extension portions 22 away from the connecting portion 21); the hair dryer also includes a limit member 30 and a power cord, the limit member 30 can be movably installed at the end portion of the extension portion 22 to open or block the winding opening 205; the power cord is arranged on the handle 20, and when the limit member 30 opens the winding opening 205, the power cord is wound around one of the extension portions 22 through the winding opening 205.

[0057] In this embodiment, the two extensions 22 are arranged roughly in parallel, and the sizes of the two extensions 22 can be the same or different. During use, the limiter 30 can be made to block the winding opening 205, and the user holds one of the extensions 22 for use. After use, when it is necessary to store it, if the limiter 30 is in a state of blocking the winding opening 205, the limiter 30 is moved to open the winding opening 205. At this time, the power cord can be wound around one or both of the extensions 22 (the power supply needs to pass through the winding space 204), and finally the limiter 30 is made to block the winding opening 205, thereby preventing the power cord from being loosened from the handle 20. In other embodiments, the distance between the two extensions 22 gradually increases in the direction away from the connecting portion 21.

[0058] Optionally, the distance between the two extensions 22 is smaller than the diameter of the power cord plug, or a buckle is provided on the side of the retaining member 30 facing the winding space 204. After the power cord is wrapped around the extension 22, the portion of the cord near the plug is locked in the buckle. Alternatively, a socket is provided at the end of the extension 22. After the power cord is wrapped around the extension 22, the plug is inserted into the socket.

[0059] The handle 20 of the technical solution of the present invention includes a connecting portion 21 and two extensions 22. By providing the two extensions 22 at intervals on the connecting portion 21 and extending in a direction away from the barrel 10, a winding space 204 is formed between the two extensions 22, and the winding space 204 forms a winding opening 205 at the ends of the two extensions 22. A movable stopper 30 is provided at the end of the extension 22, so that the stopper 30 can move relative to the extension 22 to open or block the winding opening 205. In this way, after use, when the hair dryer needs to be stored, the stopper 30 can be moved first to open the winding opening 205, so that the power cord can pass through the winding space 204 and be wound around at least one extension 22. Finally, the stopper 30 is made to block the winding opening 205, thereby confining the power cord wound around the extension 22 within the winding space 204, and preventing the power cord from loosening from the handle 20. In this way, the power cord can be effectively fixed on the handle 20, which can prevent the power cord from spreading out during storage, and also allows the power cord to be neatly stored on the hair dryer, making storage of the power cord more convenient.

[0060] In some embodiments, a stopper 30 is rotatably mounted on the end of one of the extensions 22, and the other extension 22 is provided with a stopper structure 24 that cooperates with the stopper 30. Specifically, the stopper 30 is rotated to open or close the winding opening 205. When the stopper 30 closes the winding opening 205, the stopper 30 cooperates with the stopper structure 24 to increase the difficulty of the stopper 30 in closing the winding opening 205. This ensures that the stopper 30 remains fixed to the extension 22 during use, reducing the risk of the stopper 30 being lost during use. The provision of the stopper structure 24 can also reduce the risk of the stopper 30 automatically opening the winding opening 205, thereby improving reliability.

[0061] Of course, in other embodiments, the stopper 30 may be detachably mounted to the end of one or both extensions 22. For example, the stopper 30 may be snap-fitted or secured to the extension 22 via a screw with a handle. Furthermore, the other extension 22 may not be provided with the stopper structure 24. When the stopper 30 is mounted only to the end of one extension 22, the stopper 30 and the other extension 22 are spaced apart (the gap between the two is smaller than the diameter of the power cord body) or in contact.

[0062] In some embodiments, the rotation axis of the stopper 30 extends along the extension direction of the extension portion 22. Specifically, the stopper 30 is mounted on the end surface of one extension portion 22, while the end surface of the other extension portion 22 is provided with a stopper structure 24. The stopper 30 rotates in the plane of the end surface of the extension portion 22. This conceals the stopper 30 and the rotation structure 11 of the extension portion 22 and simplifies the structure. Of course, in other embodiments, the rotation axis of the stopper 30 can also be perpendicular to the extension direction of the extension portion 22. Alternatively, the extension portion 22 can be provided with a universal ball joint, and the stopper 30 is rotatably mounted on the universal ball joint.

[0063] In some embodiments, the retaining member 30 includes a mounting hole 32 and a rotating portion 33 surrounding the mounting hole 32. The rotating portion 33 is rotatably mounted on the extension portion 22, and the mounting hole 32 is in communication with the inner cavity of the extension portion 22. The hair dryer also includes a wire guide 40, which is mounted in the mounting hole 32 and sleeved around the power cord. The inner diameter of the guide 40 is larger than the size of the power cord. Specifically, the axis of the mounting hole 32, the axis of the guide 40, and the rotation axis of the retaining member 30 are substantially colinear, thereby securing the power cord to the extension portion 22. Passing the power cord through the wire guide 40 effectively allows the retaining member 30 to rotate around the power cord. Because the inner diameter of the guide 40 is larger than the size of the power cord, the retaining member 30 can be prevented from rotating and twisting the power cord. Of course, in other embodiments, the power cord can be mounted on the side of the extension portion 22; or the retaining member 30 can be rotatably mounted on one extension portion 22, while the power cord is mounted on the other extension portion 22.

[0064] In some embodiments, the end surface of the extension portion 22 is provided with a clearance hole 221. The limiting structure 24 includes a clamping member 241 having a clamping portion 242 that movably extends from the clearance hole 221. The limiting member 30 is provided with a slot 31 that cooperates with the clamping portion 242. When the limiting member 30 rotates to the clamping portion 242, the clamping portion 242 snaps into the slot 31. Specifically, when the limiting member 30 rotates to the clearance hole 221, the clamping portion 242 extends from the clearance hole 221 and snaps into the slot 31, thereby limiting the rotation of the limiting member 30. When the clamping portion 242 retracts from the clearance hole 221 and exits the slot 31, the limiting member 30 can be rotated to open the winding opening 205. This can enhance the limiting effect of the limiting member 30 and the limiting structure 24 and reduce the risk of the limiting member 30 rotating automatically. Of course, in other embodiments, the limiting member 30 is provided with a first magnet, the limiting structure 24 includes a second magnet, and the first magnet is magnetically connected to the second magnet.

[0065] In some embodiments, the retaining structure 24 further includes an elastic member 243, which is mounted between the engaging member 241 and the extension portion 22 and has an elastic deformation that forces the engaging member 242 to extend from the avoidance hole 221. Specifically, the portion of the engaging member 242 extending from the avoidance hole 221 is generally spherical, while the edge of the slot 31 transitions into a circular arc. The elastic member 243 is a compression spring and is mounted within the portion of the engaging member 241 located within the extension portion 22. As a result, when the retaining member 30 rotates until its edge abuts the engaging member 242, the engaging member 242 is squeezed, causing it to move toward the avoidance hole 221, compressing the elastic member 243. When the retaining member 30 rotates until the slot 31 corresponds to the avoidance hole 221, the elastic member 243 forces the engaging member 242 to engage the slot 31. When the winding opening 205 needs to be opened, the user manually rotates the stopper 30. When the force applied by the user overcomes the friction between the clamping portion 242 and the clamping slot 31 and the elastic force of the elastic member 243, the clamping portion 242 is automatically squeezed into the avoidance slot, thereby rotating the stopper 30 to open the winding opening 205. This eliminates the need for the user to manually move the clamping portion 241, making it more convenient to use. Of course, in other embodiments, a toggle member can also be provided on the outside of the extension portion 22 to drive the clamping portion 242 to extend and retract into the avoidance hole 221.

[0066] In some embodiments, a rotating structure 11 is provided on the end of the body 10 away from the air outlet 101; a connecting portion 21 is rotatably mounted on the rotating structure 11, and the rotation axis of the handle 20 is inclined relative to the axis of the body 10. The handle 20 has an in-use state and a stowed state. When the handle 20 is rotated relative to the body 10 to the in-use state, the handle 20 is arranged at an angle with the body 10. When the handle 20 is rotated relative to the body 10 to the stowed state, the handle 20 extends along the axis of the body 10 to form a straight cylindrical structure with the body 10. This effectively secures the power cord to the handle 20 when the hair dryer is stored, preventing the power cord from becoming untied during storage. It also reduces the size of the hair dryer in a direction perpendicular to the axis of the body 10, thereby reducing the space occupied by the hair dryer when stowed (i.e., the storage space), making it easier to store the hair dryer and improving its convenience. Of course, in other embodiments, the handle 20 is fixedly mounted to the side of the body 10, for example, the handle 20 housing 12 is integrally formed with the body 10 housing 12.

[0067] In some embodiments, the connecting portion 21 is rotatably mounted on the annular portion 114, and the connecting portion 21 is provided with an air duct cavity 201 and a first air inlet 202. The first air inlet 202 is provided on the connecting portion 21 so that the first air inlet 202 is not blocked when the extension portion 22 is held.

[0068] In some embodiments, the connecting portion 21 is provided with at least two first air inlets 202, one of which is located between the two extensions 22, and the other is located on the side of the connecting portion 21. By utilizing the area between the two extensions 22 and the side of the connecting portion 21 to provide the first air inlets 202, the air intake area can be increased, thereby facilitating increased air delivery from the hair dryer. Of course, in other embodiments, only one first air inlet 202 may be provided.

[0069] In some embodiments, the body 10 is provided with a second air inlet 102, which is connected to the air supply duct 103 and is located on the side of the air supply assembly 14 away from the air outlet 101. This can increase the air intake area, which is conducive to increasing the air supply volume of the hair dryer. Of course, in other embodiments, the second air inlet 102 may not be provided, or only the second air inlet 102 may be provided.

[0070] In some embodiments, the barrel body 10 further includes a heating device 15 , which is disposed in the air supply duct 103 and between the air outlet 101 and the air supply assembly 14 , so as to heat the air flow blowing toward the air outlet 101 through the heating device 15 .

[0071] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
