[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a patent application filed with the State Intellectual Property Office of China on November 2, 2023, with application number 202322966048.5 and utility model name “Blowing Device”, the entire contents of which are incorporated by reference in this application. Technical Field

[0003] The utility model belongs to the technical field related to blowing equipment, and in particular relates to a rotating component and a blowing device. Background Art

[0004] As a kind of hair-drying equipment, hair dryer is widely used in life and work, and one of its main functions is to dry hair.

[0005] However, the current hair dryers can only be used with the handle and the hair dryer vertically arranged for easy hand-held blowing, and some hair dryers have foldable handles for easy storage. In fact, the hair dryers can only be used when the handle and the hair dryer are vertical. The above-mentioned prior art settings are not suitable for special scenes. For example, in some hairdressing needs, the handle and the hair dryer need to be switched between multiple different positions. Compared with the current hair dryers, which only have the vertical arrangement of the handle relative to the hair dryer, they cannot meet the needs of hairdressing in multiple scenes.

[0006] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

[0007] Therefore, the technical problem to be solved by the utility model is that the hair dryer in the prior art cannot meet the multi-angle requirements of the relative position between the handle and the hair dryer for hairdressing during use.

[0008] In order to solve the above technical problems, the utility model provides a hair dryer, which includes a hair dryer; a handle; a rotating assembly, wherein the handle is rotatably connected to the hair dryer through the rotating assembly, and the handle has a first position, a second position, and a third position arranged between the first position and the second position, which are engaged with the rotating assembly; the angle between the axis direction of the handle when it is in the first position and the axis direction of the handle when it is in the second position is an obtuse angle or a straight angle; when the handle is in the third position, the angle between the axis direction of the handle and the axis direction of the handle when it is in the first position or the axis direction of the handle when it is in the second position is an acute angle or a right angle. The hair dryer realizes the switchable setting of the handle between the first position, the second position, and the third position through the rotating assembly, and the hair dryer and the handle can be adjusted in position within the range of 0-180°, which meets the multi-angle requirements of the relative position between the hair dryer and the handle during the use of the hair dryer, provides an applicable range of the hair dryer, and improves the user experience.

[0009] Optionally, when the handle is in the first position or the second position, the axial direction of the handle is parallel to the axial direction of the hair dryer; and / or when the handle is in the third position, the axial direction of the handle is perpendicular to the axial direction of the hair dryer. The handle of the present application can be arranged parallel to the hair dryer when it is in the first position and the second position, so as to facilitate the storage of the hair dryer or meet the hairdressing needs, enrich the adjustable positions of the handle, and enhance the practicality of the hair dryer; the handle is in the third position for easy hand-held hair drying, and the adjustment of multiple angles is conducive to improving the operability of the hair dryer and improving the user experience.

[0010] Optionally, when the handle is in the second position, the hair dryer is used to connect with a hair curling accessory. By adjusting the handle to the second position, the hair dryer provides an installation position for the hair curling accessory. After the hair curling accessory is installed, the hair curling operation can be performed by holding the handle and rotating the handle to drive the hair curling accessory to rotate, which is convenient to operate, improves the applicable scenarios of the hair dryer, and is more practical.

[0011] Optionally, the ratio of the diameter D1 of the outer wall of the wind tube to the length L1 of the wind tube is in the range of 0.22 to 0.43. When the ratio of the diameter D1 of the outer wall of the wind tube to the length L1 of the wind tube satisfies 0.22 to 0.43, the overall structure of the wind tube is compact, which is conducive to improving the air outlet efficiency.

[0012] Optionally, D1 is less than or equal to 60 mm, and L1 is less than or equal to 180 mm. If the diameter D1 of the outer wall of the hair dryer is greater than 60 mm, it is not conducive to wind gathering and affects the wind speed output by the hair dryer; if the length L1 of the hair dryer is greater than 180 mm, the wind flow path is too long, affecting the wind output efficiency. If the length of the hair dryer is too long, it will affect the convenience of the user when using it in different positions. For example, when the handle is in the first position, the storage length of the hair dryer is increased; or when the handle is in the second position, after the curling attachment is connected, the overall length is longer, affecting the comfort of the user when curling.

[0013] Optionally, the diameter D2 of the outer wall of the handle is less than or equal to 50 mm, and the length L2 of the handle is less than or equal to 180 mm. The diameter D2 of the outer wall of the handle is less than or equal to 50 mm, which is convenient for holding and facilitating hair drying; the length L2 of the handle is less than or equal to 180 mm, which avoids the problem of the handle being too long and inconvenient to place and occupying space.

[0014] Optionally, when the handle is in the second position, the distance L3 between the end point of the air outlet of the air duct and the end point of the top of the handle projected on the horizontal plane is between 90-110 mm. The projected distance L3 is between 90-110 mm to ensure that the overall length of the air duct and the handle is moderate to avoid being too long or too short to cause inconvenience in operation. Using L3 to meet 90-110 mm is conducive to the effect of facilitating user operation.

[0015] Optionally, when the handle is in the second position, the distance L4 between the end point of the air inlet of the hair dryer and the end point of the handle tail projected on the horizontal plane is greater than or equal to 70 mm, so as to ensure that the user can hold the handle when the handle is in the second position, and an area for the user to hold is reserved on the handle, so that when the handle is in the second position, the user can hold the handle to complete the hair blowing or hair styling operation. For example, when using a curling iron, the user can perform the hair curling operation better, the handle of the hair dryer will not interfere with the user's body, the operation space of the hair curling is larger, and it is closer to the use of a straight-handled curling iron, which can make the handle of the hair dryer farther away from the user's face, avoiding the problem of the handle of the hair dryer abutting the face when the user uses the hair dryer, and facilitating the user's use. Of course, the handle is not limited to the second position or the third position mentioned above, and can also be in a position between the second position and the third position, such as the position when the handle is rotated 135° can also be fixed, and the user can complete the hair blowing or hair styling operation according to his or her own physical condition and the blowing direction requirements, thereby improving the user's convenience in using the hair dryer.

[0016] Optionally, when the handle is in the second position, the axis of the handle is parallel to the axis of the hair dryer, and the distance between the two axes is less than or equal to 55 mm. The distance between the two axes satisfies the requirement of being less than 55 mm, which makes it convenient to drive the hair dryer to rotate in a small range by turning the handle, which is beneficial to improving the precision and stability of blowing. Alternatively, when the distance satisfies the requirement of being less than 55 mm, the user can hold the handle and the hair dryer at the same time to complete hair blowing or hairdressing operations. For example, when using a curling iron, the user can perform a better curling operation, the handle of the hair dryer will not interfere with the user's body, the curling operation space is larger, and it is closer to the use of a straight-handled curling iron, which is convenient for users to use.

[0071] Embodiment 1

[0072] The utility model solves the problem that the hair dryer in the prior art cannot meet the multi-angle requirements of the relative position between the handle and the hair cylinder for hairdressing during use.

[0073] like Figures 1 to 19As shown, this embodiment provides a blowing device, which includes a hair dryer 10, a handle 30 and a rotating assembly 20. The handle 30 is rotatably connected to the hair dryer 10 through the rotating assembly 20. The handle 30 has a first position, a second position and a third position arranged between the first position and the second position for clamping with the rotating assembly 20. The angle between the axial direction of the handle 30 when it is in the first position and the axial direction of the handle 30 when it is in the second position is an obtuse angle or a straight angle. When the handle 30 is in the third position, the angle between the axial direction of the handle 30 and the axial direction of the handle 30 when it is in the first position or the axial direction of the handle 30 when it is in the second position is an acute angle or a right angle.

[0074] Specifically, the hair dryer 10 and the handle 30 of the hair dryer of the present application are switchably set between the first position, the second position and the third position through the rotating assembly 20. When the hair dryer 10 and the handle 30 are in the first position and the second position, the extension directions are opposite, so that the hair dryer 10 and the handle 30 can be adjusted in the range of 0°-180°, so as to meet the requirements for different positions between the hair dryer 10 and the handle 30 during the use of the hair dryer, provide a scope of application of the hair dryer, and improve the user experience. At the same time, the handle 30 of the present application can be set parallel to the hair dryer 10 when it is in the first position and the second position, such as Figure 2 and Figure 3 As shown, the hair dryer can be stored conveniently or the hairdressing needs can be met, the adjustable positions of the handle 30 are enriched, and the practicality of the hair dryer is enhanced.

[0075] Furthermore, when the handle 30 is in the first position, the end of the handle 30 away from the wind cylinder 10 is close to the air outlet side of the wind cylinder 10; when the handle 30 is in the second position, the end of the handle 30 away from the wind cylinder 10 is close to the air inlet side of the wind cylinder 10.

[0076] Furthermore, when the handle 30 is in the first position, the axial direction of the handle 30 is parallel to the axial direction of the hair cylinder 10, and the hair dryer is in a folded state, which makes it convenient to store the hair dryer.

[0077] Furthermore, when the handle 30 is in the second position, the axial direction of the handle 30 is parallel to the axial direction of the hair dryer 10, and the hair-drying device is in an unfolded state, which is suitable for hairdressing needs.

[0078] Furthermore, when the handle 30 is in the third position, the axial direction of the handle 30 is perpendicular to the axial direction of the hair dryer 10, so that the handle 30 can be held conveniently for blowing.

[0079] like Figure 3As shown, when the handle 30 is in the second position, the hair-drying device is used to connect with a curling accessory. The curling accessory is installed on one side of the air outlet of the hair dryer 10, and can be connected in a magnetic way. During use, the handle 30 can be held and the curling accessory can be rotated to achieve the curling operation. The curling accessory can be a comb-tooth structure, and of course, it can also be other structures that can achieve curling.

[0080] Further, the ratio of the diameter D1 of the outer wall of the air duct 10 to the length L1 of the air duct 10 of this embodiment is in the range of 0.22 to 0.43. In this embodiment, D1 is less than or equal to 60 mm, and L1 is less than or equal to 180 mm. Preferably, D1 is between 40-60 mm, and L1 is between 140-180 mm. More preferably, D1 is 56 mm, and L1 is 145 mm.

[0081] In this embodiment, the diameter D2 of the outer wall of the handle 30 is less than or equal to 50 mm, and the length L2 of the handle 30 is less than or equal to 180 mm. Preferably, D2 is 36 mm, and L2 is 150 mm.

[0082] When the handle is in the second position, the axis of the handle is parallel to the axis of the wind tube, and at least one of the axis of the handle and the axis of the wind tube is parallel to or coincides with the horizontal plane, and the plane where the axis of the handle and the axis of the wind tube are located is perpendicular to the horizontal plane. In the projection on the horizontal plane, the distance L3 between the air outlet end point of the wind tube 10 and the top end point of the handle 30 is between 90-110 mm, and the distance L4 between the air inlet end point of the wind tube and the tail end point of the handle is greater than or equal to 70 mm. Preferably, L3 is 98 mm, and L4 is 85 mm. The setting distance of L4 is determined according to the usage. When the handle 30 is in the second position, the hair-drying device is roughly in the shape of "1". The distance of L4 should ensure that the hand can hold the handle 30, so as to perform hairdressing and other operations. Further, the switch button set on the handle 30 should also avoid the wind tube 10 to prevent interference with the operation of the switch button in the second position.

[0083] Preferably, when the handle is in the first position, the second position and the third position, the handle is in the same plane. That is, the handle can switch to different positions in a certain plane. It should be understood that the handle can also switch positions with more degrees of freedom.

[0084] It should be understood that the handle 30 is reserved for the user to hold, so that when the handle 30 is in the second position, the user can hold the handle 30 to complete the hair blowing or hair styling operation. For example, when the hair dryer is attached with a curling iron, the user can perform the hair curling operation better, the handle of the hair dryer will not interfere with the user's body, the hair curling operation space is larger, and it is closer to the use of a straight-handled curling iron, which is convenient for the user. Of course, the handle 30 is not limited to the second position or the third position mentioned above, and can also be in a position between the second position and the third position, such as the position when the handle 30 is rotated to 135° can also be fixed, and the user can complete the hair blowing or hair styling operation according to his or her physical condition and the blowing direction requirements.

[0085] Furthermore, when the handle 30 is in the second position, the axis of the handle 30 is parallel to the axis of the hair dryer 10, and the distance between the two axes is less than or equal to 55 mm. The distance between the two axes satisfies the requirement of being less than 55 mm, which makes it convenient to drive the hair dryer to rotate in a small range by turning the handle, and is beneficial to improving the precision and stability of blowing. Alternatively, when the distance is less than 55 mm, the user can hold the handle 30 and the hair dryer 10 at the same time to complete hair blowing or hairdressing operations. For example, when a curling iron accessory is attached, the user can perform a better hair curling operation, the handle of the hair dryer will not interfere with the user's body, the hair curling operation space is larger, and it is closer to the use of a straight-handled curling iron, which is convenient for users to use. Fig.19 shown.

[0086] More preferably, the distance between the two axes is between 45-50 mm.

[0087] It should be understood that the length of a component refers to the maximum length of the component in the axial direction. For example, the length L1 of the air cylinder 10 is the length from the air outlet end point to the air inlet end point in the axial direction of the air cylinder 10, and the length L2 of the handle 30 is the length from the top end of the handle 30 to the tail end of the handle 30 in the axial direction of the handle 30. Similarly, the diameter of the outer wall of a component refers to the maximum diameter of the outer wall of the component. For example, the diameter D2 of the outer wall of the handle 30 is the maximum diameter of the handle 30 from the top end of the handle 30 to the tail end of the handle 30. In special cases, such as when the outer wall of a component is an ellipse or polygon that is approximately circular, the diameter of the outer wall of the component is the diameter of the smallest circumscribed circle of the outer wall of the component.

[0088] like Figures 1 to 14 As shown, the rotating assembly 20 includes a main body 210 and a transmission part 220 . The first end of the main body 210 is fixedly connected to the wind tube 10 , and the second end of the main body 210 is rotatably connected to the transmission part 220 . The transmission part 220 is also fixedly connected to the handle 30 .

[0089] Specifically, the main body 210 is fixedly connected to the hair dryer 10 to achieve the connection function, the transmission part 220 is fixedly connected to the handle 30, and the rotational connection between the handle 30 and the hair dryer 10 is achieved through the rotational cooperation of the main body 210 and the transmission part 220.

[0090] Furthermore, the second end of the main body 210 has a circular groove structure 211, and at least a portion of the transmission part 220 is rotatably disposed inside the circular groove structure 211, so that at least a portion of the transmission part 220 can rotate inside the circular groove structure 211, thereby realizing rotational coordination between the main body 210 and the transmission part 220.

[0091] In this embodiment, the rotating assembly 20 further includes a limiting structure 230, which includes a limiting member, which defines a first clamping position, a second clamping position, and a third clamping position, respectively corresponding to the first position, the second position, and the third position of the handle 30. The limiting member is used to provide the first clamping position, the second clamping position, and the third clamping position, thereby realizing the switching of the clamping position between the transmission part 220 and the main body part 210 through the limiting member, so that the handle 30 can switch between the first position, the second position, and the third position.

[0092] like Figures 1 to 14 As shown, the limiting member includes a first limiting member 231 and a second limiting member 232 that cooperate with each other in limiting positions. The first limiting member 231 is arranged on the inner circumferential wall surface of the circular groove structure 211 , and the second limiting member 232 is arranged on the transmission part 220 .

[0093] Specifically, the first limit member 231 and the second limit member 232 are matched to limit each other, and there are a first clamping position, a second clamping position and a third clamping position between the first limit member 231 and the second limit member 232, so that the relative position between the handle 30 and the hair dryer 10 can be switched by switching the clamping positions of the first limit member 231 and the second limit member 232.

[0094] Furthermore, at least three first limiting members 231 are arranged along the circumference of the circular groove structure 211 , and the second limiting members 232 are arranged in cooperation with the first limiting members 231 . The three first limiting members 231 arranged along the circumference of the circular groove structure 211 are used to provide three clamping positions.

[0095] In this embodiment, one of the first limiting member 231 and the second limiting member 232 is a limiting groove, and the other is a limiting protrusion, and at least a portion of the limiting protrusion can extend into the interior of the limiting groove. The first limiting member 231 and the second limiting member 232 use the structure of the limiting groove and the limiting protrusion to achieve the snap-fitting, and the limiting grooves can be provided with at least three, or the limiting protrusions can be provided with at least three, and of course, the limiting grooves and the limiting protrusions can be provided with three, and the limiting protrusions and the limiting grooves correspond to each other one by one.

[0096] like Figures 1 to 14 As shown, the handle 30 includes a first shell 310 and a second shell 320 that are detachably connected, and the first shell 310 and the second shell 320 form an installation cavity 301 toward the first end of the hair dryer 10, at least a portion of the second end of the main body 210 is accommodated inside the installation cavity 301, and at least a portion of the transmission part 220 is drivingly connected to the second shell 320.

[0097] Specifically, the second housing 320 of the handle 30 drives the transmission part 220 to rotate relative to the main body 210 , thereby achieving position switching of the handle 30 relative to the hair dryer 10 .

[0098] In this embodiment, the transmission part 220 includes a transmission bracket 222 and a shift ring 221. The transmission bracket 222 is drivingly connected to the second shell 320. The shift ring 221 is arranged on the side of the transmission bracket 222 away from the second shell 320. The shift ring 221 is rotatably arranged inside the circular groove structure 211. A second limit piece 232 is arranged on the outer peripheral surface of the shift ring 221. The transmission bracket 222 is drivingly connected to the shift ring 221.

[0099] The second shell 320 rotates synchronously with the transmission bracket 222, and the transmission bracket 222 rotates synchronously with the shifting ring 221. The shifting ring 221 and the main body 210 have three clamping positions through the first limit member 231 and the second limit member 232, thereby realizing the switching of the handle 30 between the three positions.

[0100] Furthermore, the transmission bracket 222 is connected to the second housing 320 via a first positioning structure, and the first positioning structure is a positioning boss and groove structure, so that the second housing 320 can drive the transmission bracket 222 to rotate. The transmission bracket 222 has one of the first boss 321 and the first groove 2223 on the side facing the second housing 320, and the second housing 320 has the other of the first boss 321 and the first groove 2223, and the transmission bracket 222 is drivingly connected to the second housing 320 via the first boss 321 and the first groove 2223.

[0101] Furthermore, the transmission bracket 222 and the shifting ring 221 are connected via a second positioning structure, which is a positioning boss and groove structure. The transmission bracket 222 has one of the second boss 2211 and the second groove 2221 on the side facing the shifting ring 221, and the shifting ring 221 has the other of the second boss 2211 and the second groove 2221. The transmission bracket 222 and the shifting ring 221 are driven and connected via the second boss 2211 and the second groove 2221.

[0102] In this embodiment, the main body 210 has a through hole 212, and the first housing 310 has a driving shaft 311 extending toward the second housing 320. The driving shaft 311 passes through the through hole 212 and is drivingly connected to the transmission part 220. The first housing 310 drives the transmission bracket 222 to rotate synchronously with the first housing 310 through the driving shaft 311, and the transmission bracket 222 drives the second housing 320 and the dial ring 221 to rotate synchronously, thereby realizing the rotation of the first housing 310, the second housing 320, the transmission bracket 222 and the dial ring 221, and the dial ring 221 is connected to the main body 210 to realize the switching of the handle 30 between three positions.

[0103] like Figures 1 to 14 As shown, one end of the driving shaft 311 away from the first housing 310 has a first stopper 3111 extending circumferentially, and the transmission part 220 has a second stopper 2222 extending circumferentially along the driving shaft 311 , and the first stopper 3111 and the second stopper 2222 are drivingly matched.

[0104] Specifically, the first stopper 3111 and the second stopper 2222 are abutted against each other, so that the first stopper 3111 and the second stopper 2222 can be driven to cooperate and rotate.

[0105] Furthermore, the first stopper 3111 and the second stopper 2222 are semicircular, and the first stopper 3111 and the second stopper 2222 cooperate to form a complete circular structure.

[0106] Furthermore, the blowing device further includes a fastener 50, and the transmission part 220 is fixedly connected to the end of the driving shaft 311 away from the first housing 310 through the fastener 50. The fastener 50 is used to achieve a fixed connection between the driving shaft 311 and the transmission part 220, thereby improving the stability of the connection between the driving shaft 311 and the transmission part 220, thereby ensuring the driving efficiency of the driving shaft 311 driving the transmission part 220, and improving the rotation efficiency of the handle 30. The fastener 50 can be a bolt or the like.

[0107] Furthermore, the fastener 50 is used to connect the drive shaft 311 and the transmission bracket 222 so that the drive shaft 311 can drive the transmission bracket 222 to rotate synchronously.

[0108] In this embodiment, the blowing device further includes a fixing member, and the body 210 of the rotating assembly 20 has a avoidance hole extending toward the wind tube 10, at least a portion of the fixing member passes through the avoidance hole, and the body 210 is connected to the wind tube 10 through the fixing member. The avoidance hole is provided on the body 210 to facilitate the fixing member to pass through the avoidance hole and be connected to the wind tube 10, and the fixing member can be a bolt or the like.

[0109] In this embodiment, the handle 30 has a mounting cavity 301 at one end facing the hair cylinder 10, at least a portion of the rotating assembly 20 is located inside the mounting cavity 301, and the hair blowing device further includes a bracket 40 disposed inside the mounting cavity 301, the bracket 40 is located on a side of the rotating assembly 20 away from the hair cylinder 10, and the bracket 40 has a supporting surface 410 that is slidably matched with the rotating assembly 20. The outer peripheral surface of the portion of the rotating assembly 20 located inside the mounting cavity 301 is a convex arc surface, and the supporting surface 410 is a concave arc surface.

[0110] Further, such as Figures 15 to 17 As shown, in this embodiment, the transmission part 220 includes a transmission bracket 222 and a shifting ring 221 , and the transmission bracket 222 and the shifting ring 221 are drivingly connected so that the transmission bracket 222 and the shifting ring 221 rotate synchronously.

[0111] Specifically, the driving bracket cooperates with the circular groove structure through the dial ring 221 to facilitate the handle 30 to be adjusted between multiple positions, thereby improving the operability of the hair dryer and facilitating the use of the user. In addition, the driving cooperation between the driving bracket 222 and the dial ring 221 facilitates the handle 30 to be fixed at one of the multiple clamping positions, thereby improving the stability of the hair dryer.

[0112] In this embodiment, the blowing device further includes a support member 60, which is disposed on the inner circumference of the dial ring 221. The support member 60 can be elastically deformed and has a stable reset capability, and is used to abut against the dial ring 221. The support member 60 supports the dial ring 221 and always provides a radially outward biasing force to the dial ring 221, so that the dial ring 221 and the circular groove structure 211 remain relatively fixed, thereby maintaining the handle 30 at the first position, the second position, or the third position.

[0113] Specifically, the support member 60 provides driving force for the second limiting member 232 to maintain the limiting cooperation with the first limiting member 231. The support member 60 can always support the dial ring 221, increase the service life of the folding handle 30 of the hair dryer, and improve the user's use experience.

[0114] In this embodiment, the support member 60 is arranged on the inner circumferential surface of the dial ring 221. The support member 60 provides a supporting force so that the dial ring 221 can be maintained at any position relative to the circular groove structure, which is beneficial to improving the positioning effect and facilitating the handle 30 to remain solid relative to the hair dryer 10 after rotating to any angle, providing convenience in use. The support member 60 can always support the dial ring 221, increase the service life of the folding handle of the hair dryer, and improve the user's experience.

[0115] The support member 60 abuts against the inner circumference of the dial ring 221, and the support member 60 radially supports the dial ring 221 outward to provide sufficient damping force, and further enables the handle 30 of the hair dryer to stay at any position relative to the hair dryer 10. For example, an angle of 47°, 115°, etc. The user can adjust and fix it at any angle according to his or her own posture and practical scene.

[0116] In the present embodiment, the rotating assembly 20 further includes a limiting structure 230, which includes a limiting member, which defines a first clamping position, a second clamping position, and a third clamping position to correspond to the first position, the second position, and the third position of the handle 30, respectively; the limiting member includes a first limiting member 231 and a second limiting member 232 that cooperate with each other in limiting positions, the first limiting member 231 being arranged on the inner circumferential wall surface of the circular groove structure 211, the second limiting member 232 being arranged on the transmission part 220, and at least three first limiting members 231 are arranged along the circumference of the circular groove structure 211, and the second limiting member 232 is arranged in cooperation with the first limiting member 231; the handle 30 includes a detachable The first shell 310 and the second shell 320 are connected, and the first shell 310 and the second shell 320 are formed with a mounting cavity 301 toward the first end of the wind tube 10. At least a part of the second end of the main body 210 is accommodated in the mounting cavity 301, and at least a part of the transmission part 220 is drivingly connected to the second shell 320; the transmission bracket 222 is drivingly connected to the second shell 320, the dial ring 221 is arranged on the side of the transmission bracket 222 away from the second shell 320, the dial ring 221 is rotatably arranged inside the circular groove structure 211, and a second limiting member 232 is arranged on the outer circumferential surface of the dial ring 221, and the transmission bracket 222 is drivingly connected to the dial ring 221. The support member 60 provides driving force for the second limiting member to maintain and the first limiting member to limit the cooperation, and the support member 60 can always support the dial ring 221, so that the handle 30 can be kept in the clamping position.

[0117] When the handle 30 is switching its position, the first limit member and the second limit member are disengaged from each other, that is, the limit protrusion and the limit groove are staggered, and the shift ring 221 is deformed into a roughly elliptical structure under the force. At this time, the support member 60 supported on the inner circumference of the shift ring 221 provides a driving force for resetting the shift ring 221, so that when the handle 30 is rotated to the first position, the second position or the third position, the first limit member and the second limit member resume the limit cooperation and maintain the cooperation state under the support of the support member 60.

[0118] When the handle 30 is at the first position, the second position, or the third position, the support member 60 provides a retaining force for the insertion and cooperation between the limiting protrusion and the limiting groove, so as to achieve stable cooperation between the shifting ring 221 and the circular groove structure 211 .

[0119] The support member 60 is supported on the shifting ring 221 and rotates synchronously with the shifting ring 221 .

[0120] In this embodiment, the support member 60 can be elastically deformed. When the handle 30 is switched between positions, the deformation of the dial ring 221 will squeeze the support member 60 to be elastically deformed. The elastically deformed support member 60 has a driving force to drive the dial ring 221 to recover. When the handle 30 is in the first position, the second position, or the third position, the support member 60 provides a force to hinder the deformation of the dial ring 221, so as to achieve stable cooperation between the dial ring 221 and the circular groove structure 211, thereby achieving that the handle 30 is kept in the first position, the second position, or the third position.

Through the structure of the cooperation between the support member 60 and the dial ring 221, under the support of the support member 60, the dial ring 221 can remain relatively fixed relative to the main body 210, thereby meeting the multi-angle requirements of the relative position between the hair dryer 10 and the handle 30 during the use of the hair dryer, providing a range of application for the hair dryer, and improving the user experience.

[0129] When the handle is in the second position, the axis of the handle is parallel to the axis of the wind tube, and at least one of the axis of the handle and the axis of the wind tube is parallel to or coincides with the horizontal plane, and the plane where the axis of the handle and the axis of the wind tube are located is perpendicular to the horizontal plane. In the projection on the horizontal plane, the distance L3 between the air outlet end point of the wind tube 10 and the top end point of the handle 30 is between 90-110 mm, and the distance L4 between the air inlet end point of the wind tube and the tail end point of the handle is greater than or equal to 70 mm. Preferably, L3 is 98 mm, and L4 is 85 mm. The setting distance of L4 is determined according to the usage. When the handle 30 is in the second position, the distance of L4 should ensure that the hand can hold the handle 30, so as to perform hairdressing and other operations. Further, the switch button set on the handle 30 should also avoid the wind tube 10, and interfere with the operation of the switch button when placed in the second position.

[0130] It should be understood that the handle 30 has a reserved area for the user to hold, so that when the handle 30 is in the second position, the user can hold the handle 30 to complete the hair blowing or hair styling operation. For example, when using a curling iron, the user can perform the hair curling operation better, the handle of the hair dryer will not interfere with the user's body, the hair curling operation space is larger, and it is closer to the use of a straight-handled curling iron, which is convenient for the user. Of course, the handle 30 is not limited to the second position or the third position mentioned above, and can also be in a position between the second position and the third position, such as the position when the handle 30 is rotated to 135° can also be fixed, and the user can complete the hair blowing or hair styling operation according to his or her physical condition and the blowing direction requirements.

[0131] Furthermore, when the handle 30 is in the second position, the axis of the handle 30 is parallel to the axis of the hair dryer 10, and the distance between the two axes is less than or equal to 55 mm. The distance between the two axes satisfies the requirement of being less than 55 mm, which facilitates the hair dryer to rotate in a small range by turning the handle, and is conducive to improving the accuracy and stability of blowing. Alternatively, when the distance satisfies the requirement of being less than 55 mm, the user can hold the handle 30 and the hair dryer 10 at the same time to complete the hair blowing or hairdressing operation. For example, when using a curling iron, the user can perform the curling operation better, the handle of the hair dryer will not interfere with the user's body, the curling operation space is larger, and it is closer to the use of a straight-handled curling iron, which is convenient for the user to use.

[0132] More preferably, the distance between the two axes is between 45-50 mm.

[0133] It should be understood that the length of a component refers to the maximum length of the component in the axial direction. For example, the length L1 of the air cylinder 10 is the length from the air outlet end point to the air inlet end point in the axial direction of the air cylinder 10, and the length L2 of the handle 30 is the length from the top end of the handle 30 to the tail end of the handle 30 in the axial direction of the handle 30. Similarly, the diameter of the outer wall of a component refers to the maximum diameter of the outer wall of the component. For example, the diameter D2 of the outer wall of the handle 30 is the maximum diameter of the handle 30 from the top end of the handle 30 to the tail end of the handle 30. In special cases, such as when the outer wall of a component is an ellipse or polygon that is approximately circular, the diameter of the outer wall of the component is the diameter of the smallest circumscribed circle of the outer wall of the component.

[0134] like Figures 15 to 17 As shown, along the circumference of the support member 60, the support member 60 is not closed to form a notch 611. The provision of the notch is beneficial to increasing the deformation effect of the support member and enhancing the elastic force of the support member.

[0135] The two ends of the support member 60 are spaced apart to form a notch 611 , and the notch 611 is connected to the deformation cavity 610 surrounded by the support member 60 to enhance the deformation effect.

[0136] Specifically, the provision of the notch 611 is conducive to increasing the deformation effect of the support member 60 and enhancing the elastic force of the support member 60. The notch 611 provides a deformable space for the support member 60, and the support member 60 is in a semi-enclosed structure to enclose a semi-enclosed deformation cavity 610, and the notch 611 is connected to the deformation cavity 610. When the support member 60 is deformed by force, the two ends of the support member 60 approach each other to make the notch 611 smaller, and the provision of the notch 611 facilitates the deformation of the support member 60.

[0137] In this embodiment, the support member is in the shape of a non-closed circular ring, so as to support the inner surface of the shift ring 221 through the ring structure.

[0138] In another embodiment, not limited to the above-mentioned non-closed circular ring structure, the support member is in a closed non-circular ring shape, such as an ellipse, a heart shape or other irregular shapes.

[0139] In this embodiment, the support member 60 provides driving force for the second limit member 232 of the limit structure 230 of the rotating assembly 20 to maintain the limit fit of the first limit member 231 of the limit structure 230. The support member 60 is provided to improve the stability of the limit fit between the first limit member 231 and the second limit member 232, thereby improving the stability of the handle 30 when it is in the clamping position.

[0140] Furthermore, the inner circumferential surface of the support member 60 has a convex point 2212 arranged in alignment with the first position-limiting member 231, and at least a portion of the support member 60 abuts against the convex point 2212. The first position-limiting member 231 and the convex point 2212 are colinear along the radial direction of the dial ring 221, thereby shortening the abutting path when the support member 60 abuts against the convex point 2212, so that the support member 60 can better provide driving force for the first position-limiting structure and the second position-limiting member.

[0141] Furthermore, along the side of the pull ring 221 away from the circular groove structure 211, the surface of the support member 60 does not protrude from the surface of the pull ring 221. The support member 60 is hidden inside the deformation cavity 610 of the pull ring 221, avoiding interference between the support member 60 and the transmission bracket 222, which may cause the problem of being unable to be installed; at the same time, the support member 60 is hidden inside the deformation cavity 610 of the pull ring 221, and the pull ring 221 has the effect of protecting the support member 60.

[0142] In this embodiment, the support member 60 is made of elastic material, and the elastic material is used to achieve good elastic force of the support member 60, so as to support the support member 60 inside the dial ring 221 to improve the good support force and improve the stability of the installation of the dial ring 221 and the circular groove structure 211. The elastic material makes the support member 60 have good toughness, long bending service life, and easy stretching deformation and recovery. Preferably, the elastic material is spring steel.

[0143] Of course, the support member 60 is not limited to being made of spring steel, and the support member 60 may also be other elastic metal members, such as copper.

[0144] It should be noted that the support member 60 of the present application is used to support the shift ring 221 so that the limiting protrusion and the limiting groove can maintain a stable snap-fit ​​fit, thereby achieving relative fixation of the shift ring 221 relative to the circular groove structure 211. At this time, the handle 30 can be maintained in the first position, the second position or the third position.

[0145] like Fig.18 As shown, in this embodiment, the blowing device further includes a protective member 70 .

[0146] Specifically, a wiring space is formed between the main body 210 and the first shell 310 , and the protective member 70 is disposed inside the wiring space, and the protective member 70 is used to wrap the line.

[0147] The circuit is used for conducting electricity, and the circuit realizes electrical connection between the electrical components inside the hair dryer and the electrical components in the handle.

[0148] In order to solve the problem of wear of the circuit due to the rotation of the handle 30 in the prior art, the present embodiment provides a protective member 70, which is wrapped around the circuit. During the rotation of the first shell 310 relative to the main body 210, the first shell 310 is not in direct contact with the circuit, which is beneficial to protecting the circuit and also helps to improve the smoothness of the rotation of the handle 30.

[0149] Furthermore, the protective member 70 has an escape channel 710 extending in the axial direction of the main body 210, and the escape channel 710 is used for the drive shaft 311 on the first shell 310 to pass through. The drive shaft 311 passes through the escape channel 710, and the inner surface of the escape channel 710 is coated on the drive shaft 311 to improve the compactness of the overall structure and facilitate the stability of the installation of the protective member 70.

[0150] Furthermore, the protective member 70 is cushioned between the first shell 310 and the main body 210 .

[0151] Furthermore, the protective member 70 of this embodiment is made of foam material, and the friction on the line is reduced by using the foam material to extend the service life of the line of the blowing device. Of course, the protective member 70 can also be made of other materials with protective effects, such as plastic material.

[0152] Furthermore, the protective member 70 is a columnar structure coaxial with the main body 210. The protective member 70 with a columnar structure is filled in the interior of the wiring space to cover all the lines, while also avoiding dirt from being hidden in the wiring space and improving the aesthetics.

[0153] In this embodiment, the protective member 70 is arranged on the main body 210, wherein the handle 30 is rotatably arranged relative to the main body 210 and the hair dryer 10. Setting the protective member 70 on the main body 210 is beneficial to the stability of the installation of the protective member 70, and is also beneficial to positioning the line to keep the line relatively fixed, which is beneficial to improving the protection effect.

[0154] This embodiment provides a rotating assembly, such as Figures 1 to 18 As shown, the rotating assembly includes a main body 210 and a transmission part 220, which is at least partially arranged in the main body 210 and rotatably connected to the main body 210. The transmission part 220 includes a transmission bracket 222, a shifting ring 221 and a support member 60. The transmission bracket 222 and the shifting ring 221 are drivingly connected, and the support member 60 is arranged on the inner circumferential surface of the shifting ring 221.

[0155] Specifically, the support member of the present application is supported on the inner circumferential surface of the dial ring, and the support member provides supporting force so that the dial ring can be maintained at any position relative to the circular groove structure, which is beneficial to improving the positioning effect and facilitating the handle to remain solid relative to the hair dryer after being rotated to any angle, providing convenience in use. The support member can always support the dial ring, increase the service life of the folding handle of the hair dryer, and improve the user's experience.

[0156] In this embodiment, the rotating assembly 20 further includes a limiting structure 230, which includes a limiting member, which defines a first clamping position and a second clamping position; the limiting member includes a first limiting member 231 and a second limiting member 232 that are matched with each other, the first limiting member 231 is arranged on the inner peripheral wall surface of the main body, the second limiting member 232 is arranged on the transmission part 220, and the second limiting member 232 is arranged in cooperation with the first limiting member 231. The support member provides a driving force for the second limiting member to maintain and the first limiting member to limit and cooperate, and the support member can always support the dial ring, so that the handle can be kept in the clamping position.

[0157] In this embodiment, the support member 60 is made of elastic material, and the elastic material is used to achieve good elastic force of the support member 60, so as to support the support member 60 inside the dial ring 221 to improve the good support force and improve the stability of the installation of the dial ring 221 and the circular groove structure 211. The elastic material makes the support member 60 have good toughness, long bending service life, and easy stretching deformation and recovery. Preferably, the elastic material is spring steel.

[0158] Of course, the support member 60 is not limited to being made of spring steel, and the support member 60 may also be other elastic metal members, such as copper.

[0159] like Figures 15 to 17 As shown, along the circumference of the support member 60, the support member 60 is not closed to form a notch 611. The provision of the notch is beneficial to increasing the deformation effect of the support member and enhancing the elastic force of the support member.

[0160] The two ends of the support member 60 are spaced apart to form a notch 611 , and the notch 611 is connected to the deformation cavity 610 surrounded by the support member 60 to enhance the deformation effect.

[0161] Specifically, the provision of the notch 611 is conducive to increasing the deformation effect of the support member 60 and enhancing the elastic force of the support member 60. The notch 611 provides a deformable space for the support member 60, and the support member 60 is in a semi-enclosed structure to enclose a semi-enclosed deformation cavity 610, and the notch 611 is connected to the deformation cavity 610. When the support member 60 is deformed by force, the two ends of the support member 60 approach each other to make the notch 611 smaller, and the provision of the notch 611 facilitates the deformation of the support member 60.

[0162] In this embodiment, the support member 60 is in a non-closed circular ring shape, so as to support the inner surface of the shift ring 221 through the ring structure.

[0163] In another embodiment, not limited to the above-mentioned non-closed circular ring structure, the support member 60 is in a closed non-circular ring shape, such as an ellipse or other irregular shapes.

[0164] In this embodiment, the support member 60 provides driving force for the second limit member 232 of the limit structure 230 of the rotating assembly 20 to maintain the limit fit of the first limit member 231 of the limit structure 230. The support member 60 is provided to improve the stability of the limit fit between the first limit member 231 and the second limit member 232, thereby improving the stability of the handle 30 when it is in the clamping position.

[0166] In this embodiment, the hair dryer realizes that the handle can be switched between the first position, the second position and the third position through a rotating assembly, and the position of the hair dryer and the handle can be adjusted in the range of 0-180°. Through the structure of the cooperation between the support member 60 and the dial ring 221, under the support of the support member 60, the dial ring 221 can remain relatively fixed relative to the main body, thereby meeting the multi-angle requirements of the relative position between the hair dryer 10 and the handle 30 during the use of the hair dryer, providing a range of application for the hair dryer, and improving the user experience.
