[0118] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0119] The technical solution in this application will be described below with reference to Figures 1-69.

[0120] As shown in Figure 1-41, an embodiment of the present application provides a blowing device, including: a main body, which is used to generate airflow; a blowing device accessory, which is installed on the main body, and the blowing device accessory is provided with an air inlet and an air outlet 20, and a flow channel is formed between the air inlet and the air outlet 20, and the blowing device accessory includes an air outlet cylinder 2 and a flow guide 3 fixedly installed on the main body, and the flow guide 3 can rotate relative to the air outlet cylinder 2; in the first state, the flow guide 3 rotates to the first position, and the air outlet direction of the flow channel is the first rotation direction; in the second state, the flow guide 3 rotates to the second position, and the air outlet direction of the flow channel is the second rotation direction opposite to the first rotation direction.

[0121] The air outlets 20 are arranged on the air outlet cylinder 2 at intervals along the circumferential direction.

[0122] To facilitate smooth flow of air from the air outlet 20 in either the first or second state along the first or second rotational direction, as shown in Figures 2 to 5 , the air outlet 2 in this embodiment includes a plurality of circumferentially spaced arcuate plates 24. The air outlet 20 is formed between two adjacent arcuate plates 24. The arcuate plates 24 have a first outer guide surface 201 and a second outer guide surface 202. The first outer guide surface 201 extends along the first rotational direction, while the second outer guide surface 202 extends along the second rotational direction. With this design, after passing through the flow channel and exiting the air outlet 20, the air can flow along the outer wall of the air outlet 2, either along the first rotational direction in the first state or along the second rotational direction in the second state, thereby enhancing the curling effect.

[0123] 3 to 6 , the air guide 3 in this embodiment includes a first inner guide surface 341 and a second inner guide surface 342. The first inner guide surface 341 extends along the first rotation direction, and the second inner guide surface 342 extends along the second rotation direction. When the air guide 3 is in the first state, the first inner guide surface 341 contacts the first outer guide surface 201, directing the airflow in the first rotation direction. When the air guide 3 is in the second state, the second inner guide surface 342 contacts the second outer guide surface 202, directing the airflow in the second rotation direction.

[0124] Furthermore, referring to Figures 2 to 6 , the flow guide 3 in this embodiment includes a flow guide member 34 and a first sealing member 35 fixedly mounted on the flow guide member 34. The flow guide member 34 and the first sealing member 35 together form a first inner flow guide surface 341 and a second inner flow guide surface 342. The first sealing member 35 is made of a flexible material. In the first state, the second secondary flow channel 4112 is blocked by the first sealing member 35 abutting against the inner wall of the air outlet duct 2. In the second state, the first secondary flow channel 4111 is blocked by the first sealing member 35 abutting against the inner wall of the air outlet duct 2. In this embodiment, the air guide component 34 is provided with a fixing groove along its axial direction, and the first sealing member 35 is fixedly installed in the sealing groove. The first sealing member 35 includes a first sealing surface 351 and a second sealing surface 352. The first side arc surface of the air guide component 34 is connected to the first sealing surface 351, and the second side arc surface of the air guide component 34 is connected to the second sealing surface 352. In the first state, the first sealing surface 351 is sealed with the inner wall of the air outlet duct 2, and in the second state, the second sealing surface 352 is sealed with the inner wall of the air outlet duct 2. The first sealing member 35 can be a sealing strip made of silicone material, which is fixedly installed on the outer wall of the air guide component 34 along the length direction of the air guide component 34.

[0125] It should be noted that the blower attachment includes a main flow channel 412 connected to the air inlet, and a first secondary flow channel 4111 and a second secondary flow channel 4112, each connected to the air outlet 20. The first secondary flow channel 4111 is formed by the first inner guide surface 341 and the inner wall of the air outlet cylinder 2, so that air flows into the main flow channel 412 and then flows out through the first secondary flow channel 4111, forming air outlet with a first rotation direction. The second secondary flow channel 4112 is formed by the second inner guide surface 342 and the inner wall of the air outlet cylinder 2, so that air flows into the main flow channel 412 and then flows out through the second secondary flow channel 4112, forming air outlet with a second rotation direction.

[0126] The guide members 34 are spaced apart circumferentially around the guide member 3 and extend axially along the air outlet 2. In the first state, the first secondary flow channel 4111 communicates with the air outlet 20, while the second secondary flow channel 4112 is blocked. In the second state, the second secondary flow channel 4112 communicates with the air outlet 20, while the first secondary flow channel 4111 is blocked. This design allows the hair dryer accessory to form a first flow channel 41 for discharging air in a first rotational direction or a second flow channel 42 for discharging air in a second rotational direction, depending on the state of the guide member 3. The first flow channel 41 consists of the main flow channel 412 and the first secondary flow channel 4111, while the second flow channel 42 consists of the main flow channel 412 and the second secondary flow channel 4112.

[0127] Preferably, in order to facilitate the air outlet direction to form the first rotation direction or the second rotation direction and to have a better air outlet effect and a higher air outlet speed, the first inner guide surface 341 and the second inner guide surface 342 in this embodiment are arc-shaped, and their curvature is greater than or basically equal to the curvature of the first outer guide surface 201 or the second outer guide surface 202; that is, it can be explained as: the first secondary flow channel 4111 includes an air inlet end and an air outlet end, and the distance between the first inner guide surface 341 and the inner wall of the air outlet tube 2 generally tends to gradually decrease from the air inlet end to the air outlet end; the second secondary flow channel 4112 includes an air inlet end and an air outlet end, and the distance between the second inner guide surface 342 and the inner wall of the air outlet tube 2 generally tends to gradually decrease from the air inlet end to the air outlet end. According to this design, the fluid in the first secondary flow channel 4111 or the second secondary flow channel 4112 will gradually compress the movement space when flowing, thereby increasing the fluid flow rate of the airflow in the accessories of the hair-drying device, thereby increasing the air outlet speed and improving the curling effect. On the other hand, it can also squeeze the fluid to flow in the air outlet direction, thereby improving the air outlet efficiency.

[0128] In the first state, in order to achieve airflow discharge in the first rotational direction, the guide member 3 is rotated to change the relative position of the guide member 34 and the inner wall of the air outlet cylinder 2, so that the first sealing surface 351 is sealed with the inner wall of the air outlet cylinder 2, the second secondary flow channel 4112 is blocked, and the first secondary flow channel 4111 is connected to the air outlet 20. Under the action of the main body, the airflow passes through the main channel 412 and then flows through the first secondary flow channel 4111, and flows out of the hair drying device accessory through the air outlet 20 and flows along the first outer guide surface 201, thereby achieving curling in the first rotational direction; In the second state, to achieve airflow in the second rotational direction, the guide member 3 is rotated to change the relative position of the guide member 34 and the inner wall of the air outlet duct 2, so that the second sealing surface 352 is sealed against the inner wall of the air outlet duct 2. The first secondary flow channel 4111 is blocked, and the second secondary flow channel 4112 is connected to the air outlet 20. Under the action of the main body, the airflow passes through the main flow channel 412, then flows through the second secondary flow channel 4112, and flows out of the hair drying device through the air outlet 20 and along the second outer guide surface 202, thereby achieving curling in the second rotational direction. This design achieves sealing and ensures the flow rate and flow rate of the fluid.

[0129] 6 to 11 , in order to facilitate the rotation of the air guide member 3, the blowing device in this embodiment further includes an operating component 7, which is fixedly mounted on the air guide member 3. A limiting structure is provided on the operating component 7 and / or the air outlet tube 2, and the air guide member 3 can be controlled to rotate between the first position and the second position by rotating the operating component 7.

[0130] Among them, the limiting structure includes a protruding structure 73 and a shift groove 252 cooperating therewith, the shift groove 252 includes a first gear groove 2521 and a second gear groove 2522, and the protruding structure 73 is offset against the first gear groove 2521 or the second gear groove 2522 to complete the fixation of the guide member 3 in the first position or the second position. Specifically, the air guide member 3 in this embodiment includes a first top plate 36, which is arranged at the end of the air guide member 34 away from the main body, and the air outlet tube 2 includes a second top plate 25, which is arranged at the end of the air outlet tube 2 away from the main body. The operating member 7 includes a rotating part 71 located above the second top plate 25, a clamping part 72 connected to the air guide member 3, and a protruding structure 73 located below the rotating part 71, and the protruding structure 73 extends radially outward. An avoidance groove 3251 and a shift groove 252 are provided on the second top plate 25, and the clamping part 72 passes through the avoidance groove 3251 and is fixedly installed with the air guide member 3, that is, the clamping part 72 is fixedly installed with the first top plate 36, and the shift groove 252 includes a first gear groove 2521 and a second gear groove 2522, and the protruding structure 73 is against the first gear groove 2521 or the second gear groove 2522.

[0131] 6 and 10 , in order to facilitate the rotation of the guide member 3 , the clamping portion 72 in this embodiment is non-circular, and a non-circular assembly hole 361 is provided on the first top plate 36 to match the clamping portion 72 . The clamping portion 72 is inserted into the assembly hole 361 so that the clamping portion 72 is fixedly mounted on the first top plate 36 of the guide member 3 .

[0132] According to this design, the operator can pinch the rotating part 71 to rotate so as to rotate the clamping part 72 connected to the guide member 3. Since the clamping part 72 is fixedly installed with the guide member 3, the guide member 3 can rotate around the axis. Since the avoidance groove 3251 is provided on the second top plate 25, it is possible to avoid the clamping part 72 from colliding with the second top plate 25 and causing motion interference when rotating. At the same time, the protruding structure 73 is matched with the first gear groove 2521 or the second gear groove 2522 to ensure that the guide member 3 rotates to the first position or the second position, so as to facilitate the state switching of the hair drying device between the first state and the second state. This rotation method makes the state switching more stable because the operating component 7 is arranged at the end of the hair drying device accessory away from the main body, thereby avoiding the rotation of the guide member 3 due to the hair being driven by the hair during the curling process.

[0133] 12 to 16 , the difference from the above embodiment is that the arc-shaped plate 24 of the air outlet duct 2 in this embodiment is provided with a receiving cavity, and the arc-shaped plate 24 includes a main plate portion 242 and a first bending portion 243 and a second bending portion 244 bent inwardly and arranged at both ends of the main plate portion 242 .

[0134] In order to facilitate wind gathering and curling, a fixed plate 240 is further provided between two adjacent curved plates 24 of the air outlet tube 2 in this embodiment, and a cover plate 245 is provided on the fixed plate. The cover plate 245 is plugged and fixed on the outer wall of the fixed plate 240. The gap between the inner wall of the cover plate 245 and the outer wall of the curved plate 24 gradually decreases from the air outlet direction, so that the cross-sectional area of ​​the flow channel along the air outlet direction can be gradually reduced, which is beneficial to the acceleration of the airflow out of the air outlet 20, and cooperates with the first outer guide surface 201 and the second outer guide surface 202 of the air outlet tube 2 to form air outlet along the first rotation direction and air outlet along the second rotation direction.

[0135] Specifically, the fixed plate 240 and the curved plate 24 in this embodiment are spaced apart in the circumferential direction. A first air outlet 2011 communicating with the first secondary flow channel 4111 and a second air outlet 2012 communicating with the second secondary flow channel 4112 are formed between the fixed plate 240 and the curved plate 24. This allows the formation of a first flow channel 41 for discharging air in a first rotational direction and a second flow channel 42 for discharging air in a second rotational direction in the hair dryer accessory. The first flow channel 41 is composed of a main flow channel 412 and a first secondary flow channel 4111, while the second flow channel 42 is composed of a main flow channel 412 and a second secondary flow channel 4112.

[0136] In order to facilitate the effect of discharging air in the first rotation direction or the second rotation direction, when the rotating air guide 3 switches to the first state or the second state, the air guide 3 is in close contact with the fixed plate 240 and the arc plate 24 .

[0137] A second seal 354 and a third seal 355 are provided on either side of the flow guide 3. When the flow guide 3 is rotated to switch between the first and second states, one of the second seal 354 or the third seal 355 abuts the fixed plate 240, while the other closely contacts the curved plate 24. Specifically, in the first state, the second seal 354 abuts the outer wall of the first bent portion 243 of the curved plate 24, while the third seal 355 abuts the surface of the fixed plate 240 facing the second bent portion 244. In the second state, the second seal 354 abuts the surface of the fixed plate 240 facing the first bent portion 243, while the third seal 355 abuts the outer wall of the second bent portion 244 of the curved plate 24.

[0138] Among them, the guide member 3 includes a guide component 34 arranged at circumferential intervals, and the guide component 34 is rotatably installed between two adjacent fixed plates 240. When the rotating guide member 3 switches between the first state and the second state, one of the second seal 354 and the third seal 355 abuts against the fixed plate 240.

[0139] Preferably, in order to achieve a better sealing effect and connect the second sealing member 354 and the third sealing member 355 , a first sealing sheet 353 disposed toward the receiving cavity and on the guide member is further provided between the second sealing member 354 and the third sealing member 355 .

[0140] To further strengthen the seal and prevent air leakage, the air guide 3 in this embodiment is further provided with a fourth sealing member. The fourth sealing member is located in the receiving chamber. When the rotating air guide 3 switches between the first and second states, the fourth sealing member is in close contact with the first bent portion 243 or the second bent portion 244. Specifically, the fourth sealing member in this embodiment includes a first sealing sheet 356 and a second sealing sheet 357 located in the receiving chamber. When the rotating air guide 3 switches between the first and second states, one of the first sealing sheet 356 or the second sealing sheet 357 is in close contact with the inner sidewall of the first bent portion 243 or the second bent portion 244. Specifically, the first sealing sheet 356 is disposed opposite the first bent portion 243, and the circumferential gap between the first sealing sheet 356 and the first bent portion 243 gradually decreases in the air outlet direction. The second sealing sheet 357 is disposed opposite the second bent portion 244, and the circumferential gap between the second sealing sheet 357 and the second bent portion 244 gradually decreases in the air outlet direction. The fourth sealing member can also play a limiting role.

[0141] In order to gather wind and curl hair, an air outlet 20 is formed between the cover plate 245 and the curved plate 24, wherein the gap between the inner wall of the cover plate 245 and the outer wall of the curved plate 24 gradually decreases in the air outlet direction, so that the cross-sectional area of ​​the flow channel along the air outlet direction can be gradually reduced, which is beneficial to accelerate the outflow of air from the air outlet 20, thereby improving the air outlet effect and increasing the air outlet speed.

[0142] Preferably, reinforcing ribs 246 are provided between the fixed plate 240 and the arc-shaped plate 24 , and the reinforcing ribs 246 are arranged at intervals along the axial direction of the air outlet duct 2 , and the distance between the reinforcing ribs 246 near the air inlet end of the air outlet duct 2 is smaller than the distance away from the air inlet end.

[0143] In addition, in this embodiment, reinforcing ribs 246 are provided between the fixing plate 240 and the arc-shaped plate 24 , and the reinforcing ribs 246 are arranged at intervals along the axial direction of the air outlet tube 2 .

[0144] Optionally, in order to cooperate with the air flow diversion and make the air flow more smoothly, the distance between the reinforcing ribs 246 near the air inlet end of the air outlet duct 2 in this embodiment is smaller than the distance away from the air inlet end.

According to this design, a first flow channel 41 for discharging air along a first rotational direction and a second flow channel 42 for discharging air along a second rotational direction can be formed in the accessory of the blowing device.

[0148] To facilitate smooth flow of air from the air outlet in either the first or second state along the first or second rotational direction, as shown in Figures 18 to 22 , the air outlet 2 in this embodiment includes a plurality of circumferentially spaced arcuate plates 24. Adjacent arcuate plates 24 are connected by a mounting plate 26. The arcuate plates 24 have a first outer guide surface 201 and a second outer guide surface 202. The first outer guide surface 201 extends along the first rotational direction, while the second outer guide surface 202 extends along the second rotational direction. The mounting plate 26 defines a second vent 261. In the first state, the second vent 261 communicates with the first air outlet 2011, and in the second state, with the second air outlet 2012. With this design, airflow, after passing through the flow channel, can flow out of either the first air outlet 2011 or the second air outlet 2012, along the outer wall of the air outlet 2, thereby enhancing the curling effect.

[0149] Specifically, referring to Figure 23, and in combination with Figures 18 to 21, the rotating member 37 in this embodiment includes a torsion portion 371 provided on the end of the air outlet tube 2 and a connecting frame 372 provided inside the air outlet tube 2, the guide component 34 includes a guide plate 343 and an inwardly extending mounting clip 344, and the air outlet tube 2 is provided with a mounting hole 262, the mounting clip 344 passes through the mounting hole 262 and is fixed to the connecting frame 372.

[0150] It can be understood that in the first state, the guide plate 343 is against the second outer guide surface 202, and the inner wall of the guide plate 343 and the outer wall of the air outlet tube 2 are combined to form a first secondary flow channel 4111 connected to the first air outlet 2011, and the first secondary flow channel 4111 and the main flow channel 412 form a first flow channel 41.

[0151] In the second state, the guide member 3 abuts against the first outer guide surface 201 , and the inner wall of the guide plate 343 and the outer wall of the air outlet tube 2 form a second secondary flow channel 4112 connected to the second air outlet 2012 . The second secondary flow channel 4112 and the main flow channel 412 form a second flow channel 42 .

[0152] Furthermore, in order to improve air tightness and prevent air flow from being disordered, the guide plate 343 in this embodiment is provided with a fifth seal (not shown in the drawings). In the first state, the fifth seal is in close contact with the second outer guide surface 202, and in the second state, the second seal is in close contact with the first outer guide surface 201.

[0153] In the first state, in order to achieve airflow discharge in the first rotational direction, the guide member 3 is rotated to change the relative position of the guide plate 343 and the outer wall of the air outlet cylinder 2, so that the fifth sealing member is sealed with the second outer guide surface 202, the second secondary flow channel 4112 is blocked, and the first secondary flow channel 4111 is connected to the outside. Under the action of the main body, the airflow passes through the main channel 412, then flows through the first secondary flow channel 4111, flows out of the hair drying device accessory, and flows along the first outer guide surface 201, thereby achieving hair curling in the first rotational direction;

This design can achieve sealing and ensure the flow rate and flow rate of the fluid.

[0155] The fifth sealing member may be a sealing strip made of silicone material, and the sealing strip is fixedly installed on the outer wall of the guide plate 343 along the length direction of the guide plate 343 .

The guide plate can rotate relative to the air outlet tube 2.

[0159] In order to block the first flow channel 41 or the second flow channel 42 , a third blocking piece 39 is provided between two adjacent through holes 38 of the guide plate in this embodiment.

[0160] In order to form a guide channel, the air outlet 2 in this embodiment further includes a partition 29 . The partition 29 is fixedly installed in the air outlet 2 . The first curved plate 27 , the second curved plate 28 , and the partition 29 enclose the guide channel.

[0161] Among them, the guide member 3 is provided with a first flow channel 41 between the first air inlet 301 and the first air outlet 2011, and a second flow channel 42 is formed between the second air inlet 302 and the second air outlet 2012. The rotating guide member 3 is used to switch the blowing device between the first state and the second state. In the first state, the guide member 3 blocks the second flow channel 42, and the first flow channel 41 is connected to the outside world. In the second state, the guide member 3 blocks the first flow channel 41, and the second flow channel 42 is connected to the outside world.

[0162] In order to form a first flow channel 41 for discharging air along the first rotational direction and a second flow channel 42 for discharging air along the second rotational direction in the accessory of the blowing device, so as to facilitate the switching of the two states by rotating the guide member 3, as shown in Figure 24, the air outlet tube 2 in this embodiment includes a plurality of first curved plates 27 and a plurality of second curved plates 28 arranged at intervals along the circumferential direction, the second curved plate 28 is located outside the first curved plate 27, the first curved plate 27 includes a first outer guide surface 201 and a second outer guide surface 202, the inner wall of the second curved plate 28 and the first outer guide surface 201 enclose a first air outlet 2011, and the inner wall of the second curved plate 28 and the second outer guide surface 202 enclose a second air outlet 2012.

[0163] 25 and 26 , the first curved plate 27 in this embodiment includes a first main portion 271 and a second main portion 272. The first outer guide surface 201 is located on the first main portion 271, and the second outer guide surface 202 is located on the second main portion 272. The second curved plate 28 includes a third main portion 281 located outside the first main portion 271 and a fourth main portion 282 located outside the second main portion 272. In the first state, the guide member 3 rotates to the first position, and the third stopper 39 abuts against two adjacent partitions 29, the second main portion 272, and the fourth main portion 282, respectively. In the second state, the guide member 3 rotates to the second position, and the third stopper 39 abuts against the partition 29, the first main portion 271, and the third main portion 281, respectively.

[0164] The inner wall of the second curved plate 28 and the first outer guide surface 201 together form a first secondary flow channel 4111 connected to the first air outlet 2011. The inner wall of the second curved plate 28 and the second outer guide surface 202 together form a second secondary flow channel 4112 connected to the second air outlet 2012. The air inlet in this embodiment includes a first air inlet 301 and a second air inlet 302. The first curved plate 27, the second curved plate 28, and the partition 29 together form a first main flow channel 4121 connected to the first air inlet 301 and a second main flow channel 4122 connected to the second air inlet 302. The first main flow channel 4121 and the first secondary flow channel 4111 form a first flow channel 41, and the second main flow channel 4122 and the second secondary flow channel 4112 form a second flow channel 42.

[0165] Furthermore, the first secondary flow channel 4111 includes an air inlet and an air outlet, and the gap between the inner wall of the first main body 271 and the outer wall of the first curved plate 27 generally decreases from the air inlet to the air outlet. The second secondary flow channel 4112 includes an air inlet and an air outlet, and the gap between the inner wall of the second main body 272 and the outer wall of the first curved plate 27 generally decreases from the air inlet to the air outlet. With this design, the fluid flowing in the first secondary flow channel 4111 or the second secondary flow channel 4112 gradually compresses the movement space, thereby increasing the flow velocity of the fluid in the hair dryer attachment, thereby increasing the air outlet speed and improving the curling effect. Furthermore, it also compresses the fluid toward the air outlet, improving the air outlet efficiency.

[0166] 29 to 35 , the blowing device in this embodiment includes: a main body 1 for generating airflow; an air outlet tube 2 which is detachably mounted on the main body 1, the air outlet tube 2 including a first connecting portion 21 and a second connecting portion 22 provided at both ends of the air outlet tube 2, and an air outlet portion provided between the first connecting portion 21 and the second connecting portion 22, wherein a plurality of air outlets 20 are circumferentially arranged on the air outlet portion; the air outlet tube 2 includes a plurality of arc-shaped plates 23 arranged at intervals in the circumferential direction, and at least part of the projections between two adjacent arc-shaped plates 23 overlap to form a plurality of air outlets 20; when the first connecting portion 21 or the second connecting portion 22 is mounted on the main body 1, a rotary airflow is formed between the air outlet 20 and the arc-shaped plate 23 of the air outlet tube 2 due to the Coanda effect.

[0167] According to this design, the hair curling operation can be completed by the hair-drying device.

[0168] It's important to explain that the Coanda effect, also known as the wall adhesion or Coanda effect, is a phenomenon in which a fluid (water or air) deviates from its original flow direction and instead follows a protruding surface. When surface friction (also known as fluid viscosity) exists between the fluid and the surface it flows over, as long as the curvature is small, the fluid will follow the surface (i.e., the outer wall of the air outlet 2), allowing the user's hair to be wrapped around the air outlet 2 with the fluid, achieving curls in a first direction in the first state or a second direction in the second state.

[0169] Among them, the air outlet 2 in this embodiment is further provided with a guide member 3, which is fixedly installed in the air outlet 2, and the guide member 3 is provided with a first air inlet 301 and a second air inlet 302. A first flow channel 41 is formed between the first air inlet 301 and the air outlet 20, and a second flow channel 42 is formed between the second air inlet 302 and the air outlet 20; in the first state, the second connecting portion 22 is installed on the main body 1, the first flow channel 41 is connected to the outside world and the air outlet direction is the first rotation direction, so the airflow generated by the main body 1 can be The air enters the blowing device from the first air inlet 301 and flows out of the blowing device from the air outlet 20, and the gas flows around the outer wall of the air outlet tube 2 along the first rotation direction; in the second state, the first connecting portion 21 is installed on the main body 1, the second flow channel 42 is connected to the outside, and the air outlet direction is a second rotation direction opposite to the first rotation direction. Therefore, the airflow generated by the main body 1 can enter the blowing device from the second air inlet 302 and flow out of the blowing device from the air outlet 20, and the gas flows around the outer wall of the air outlet tube 2 along the second rotation direction. According to this design, the air outlet tube 2 can be installed by plugging and flipping it to change the air outlet direction of the flow channel, thereby achieving two air outlet effects with different rotation directions. The present application has a simple structure, and the air outlet tube 2 can be quickly and securely plugged into the main body 1. The same air outlet effect can be maintained stably for a long time during use, avoiding the situation of sudden changes in the air outlet direction, preventing the user's hair from being tangled and chaotic, and improving the effect and efficiency of curling hair.

[0170] Optionally, the first connection part 21 or the second connection part 22 can be fixedly installed on the main body 1 by means of snap connection, magnetic attraction, etc. The main body 1 can be a hairdressing device that can generate high-speed airflow, such as a hair styling device and a hair dryer. The air outlet direction can be a straight line air outlet or a non-straight line air outlet along the outer wall of the air outlet tube 2. The first rotation direction is defined as the air flow flowing roughly clockwise along the outer wall of the air blowing device accessory, and the second rotation direction is defined as the air flow flowing roughly counterclockwise along the outer wall of the air blowing device accessory. Of course, the present application is not limited to this. In order to seal the end of the air outlet tube 2 away from the main body 1, the air outlet tube 2 in another embodiment is also provided with an end cover, which can be installed and cooperated with the first connection part 21 or the second connection part 22 to play a role in blocking the gas. When one of the first connection part 21 and the second connection part 22 is installed on the main body 1, the end cover is installed on the other of the first connection part 21 and the second connection part 22, so that the air flow can only flow out from the air outlet.

[0171] To form the first flow channel 41 and the second flow channel 42, as shown in FIG37 , the flow guide 3 in this embodiment includes: a first end plate 31 including first baffles 311 spaced apart along the circumference of the flow guide 3; a second end plate 32 including second baffles 321 spaced apart along the circumference of the flow guide 3; and connecting plates 33 spaced apart along the circumference of the flow guide 3 and disposed between the first end plate 31 and the second end plate 32. Two adjacent connecting plates 33 and the first baffles 311 enclose at least a portion of the first flow channel 41, while two adjacent connecting plates 33 and the second baffles 321 enclose at least a portion of the second flow channel 42. Specifically, the two adjacent connecting plates 33 and the first baffles 311 enclose a first main flow channel 4121 connected to the first air inlet 301; and the two adjacent connecting plates 33 and the second baffles 321 enclose a second main flow channel 4122 connected to the second air inlet 302. Specifically, in this embodiment, the first ends of two adjacent connecting plates 33 are connected to the first baffle 311, and the second ends of the two adjacent connecting plates 33 are connected to the second baffle 321; the first baffle 311 and the second baffle 321 are respectively arranged on two opposite surfaces of a connecting plate 33, and the first baffle 311 and the second baffle 321 are respectively located at the two ends of a connecting plate 33.

[0172] According to this design, in the first state, the second connection part 22 of the air outlet duct 2 is fixedly installed on the main body 1, so that the second air inlet 302 cannot take in air, and the first air outlet 2011 is connected to the outside world and can take in air under the action of the main body 1; in the second state, the first connection part 21 of the air outlet duct 2 is fixedly installed on the main body 1, so that the first air inlet 301 cannot take in air, and the second air outlet 2012 is connected to the outside world and can take in air under the action of the main body 1.

[0173] Because the first main channel 4121 and the second main channel 4122 are evenly spaced along the circumference of the flow guide 3, the secondary channel 411 and the first main channel 4121 form the first channel 41, and the secondary channel 411 and the second main channel 4122 form the second channel 42. The air outlets 20 connected to the first channel 41 and the air outlets 20 connected to the second channel 42 are evenly distributed on the air outlet portion, ensuring uniform air flow along the circumference of the hair dryer in either the first or second state, resulting in a better and more uniform curling effect.

[0174] Preferably, nine first flow channels 41 and nine second flow channels 42 are provided.

[0175] Since the air outlet portion in this embodiment includes a plurality of arc-shaped plates 24 spaced apart along the circumferential direction, at least a portion of the first flow channel 41 or the second flow channel 42 is formed between two adjacent arc-shaped plates 24. In this embodiment, a secondary flow channel 411 connected to the air outlet 20 is formed between two adjacent arc-shaped plates 24. It is understandable that the arc-shaped plates 24 are all spaced apart along the circumference of the air outlet portion along the same rotation direction. Since the first connecting portion 21 or the second connecting portion 22 of the air outlet cylinder 2 can be rotated 180 degrees and installed on the main body 1, the secondary flow channel 411 changes its air outlet direction compared to the main body 1.

[0176] As shown in Figure 36, the curved plate 24 in this embodiment includes: a connecting portion 231 fixedly mounted to the guide member 3; a guide portion 232 connected to the connecting portion 231 and extending outward; wherein the secondary flow channel 411 includes an air inlet end connected to the first main flow channel 4121 or the second main flow channel 4122 and an air outlet end connected to the outside world. The gap between the inner sidewall of the guide portion 232 and the outer sidewall of the connecting portion 231 generally decreases gradually from the air inlet end to the air outlet end. According to this design, the fluid in the secondary flow channel 411 gradually compresses the movement space as it flows, thereby increasing the fluid flow velocity in the hair blowing device, thereby increasing the air outlet speed and improving the curling effect. On the other hand, it also squeezes the fluid toward the air outlet direction, improving the air outlet efficiency.

[0177] Preferably, in other embodiments, the spacing between the opposing surfaces of two adjacent connecting plates 33 of the first main channel 4121 gradually decreases along the air inlet direction; in addition, the spacing between the opposing surfaces of two adjacent connecting plates 33 of the second main channel 4122 gradually increases along the air outlet direction. Specifically, the connecting plates 33 in this embodiment include a first connecting plate 331 and a second connecting plate 332, which are spaced apart from each other. The first end of the first connecting plate 331 is connected to the first baffle 311; the second end of the first connecting plate 331 is connected to the second baffle 321; the first end of the second connecting plate 332 is connected to the first baffle 311, and the second end of the second connecting plate 332 is connected to the second baffle 321; and the angle between the first connecting plate 331 and the second connecting plate 332 is an acute angle.

[0178] Therefore, in the first connecting plate 331 and the second connecting plate 332 forming the first main channel 4121, the surface of the first connecting plate 331 facing the second connecting plate 332 is defined as the first surface 3311, and the surface of the second connecting plate 332 facing the first connecting plate 331 is defined as the second surface 3321, and the gap between the first surface 3311 and the second surface 3321 gradually increases along the air outlet direction.

[0179] According to this design, the fluid in the flow channel will gradually compress the movement space when flowing, thereby increasing the fluid flow rate of the airflow in the blowing device, thereby increasing the air outlet speed and improving the curling effect. On the other hand, it can also squeeze the fluid to flow in the air outlet direction, thereby improving the air outlet efficiency.

[0180] Of course, the present application is not limited to this. When only the distance between the opposite surfaces of the two adjacent connecting plates 33 of the first main channel 4121 gradually increases along the air outlet direction, the air outlet speed and air outlet efficiency of the first channel 41 can be improved; or, only the distance between the opposite surfaces of the two adjacent connecting plates 33 of the second main channel 4122 gradually increases along the air outlet direction, the air outlet speed and air outlet efficiency of the second channel 42 can be improved, which can also achieve the purpose of the present application and does not deviate from the design concept and purpose of the present application. Therefore, technical personnel in this field should understand that these technical solutions should all be within the protection scope of the present application.

[0181] Preferably, as shown in Figures 38 and 39, in this embodiment, the second baffle 321 is provided with a first diverter 51 extending axially outwardly parallel to the guide member 3. The thickness of the first diverter 51 gradually increases along the air inlet direction, thereby guiding the airflow into the first main channel 4121. The first baffle 311 is provided with a second diverter 52 extending axially outwardly parallel to the guide plate 343. The thickness of the second diverter 52 gradually increases along the air inlet direction, thereby guiding the airflow into the second main channel 4122. According to this design, the resistance of the fluid entering the blowing device can be reduced, the air intake efficiency can be improved, and the noise can be reduced. Of course, the present application is not limited to this. When only the first diverter 51 is provided on the second baffle 321 or the second diverter 52 is provided on the first baffle 311, both can achieve the effect of reducing the resistance of the fluid entering the blowing device, improving the air intake efficiency, and reducing noise. This does not deviate from the design concept and purpose of the present application. Therefore, those skilled in the art should understand that these technical solutions should all be within the scope of protection of the present application.

[0182] In addition, referring to Figures 40 and 41, the blowing device in this embodiment further includes: a first guide member 61, which is provided between two adjacent connecting plates 33 and located in the first main channel 4121, and the first guide member 61 is gradually bent toward the air outlet 2 along the air inlet direction; a second guide member 62, which is provided between two adjacent connecting plates 33 and located in the second main channel 4122, and the second guide member 62 is gradually bent toward the air outlet 2 along the air inlet direction. It can be understood that since the air inlet direction and the air outlet direction are approximately 90 degrees, the provision of the first guide member 61 can guide the airflow in the first main channel 4121 to the secondary channel 411, and the provision of the second guide member 62 can guide the airflow in the second main channel 4122 to the secondary channel 411, thereby ensuring a rapid air outlet effect of the entire blowing device.

[0183] Because the fluid velocity near the first air inlet 301 or the second air inlet 302 is very high when it first enters the hair dryer, making it difficult to guide the fluid, the first guide member 61 in this embodiment is arranged axially parallel to the guide member 3, with the spacing between two adjacent first guide members 61 gradually decreasing along the air inlet direction; the second guide member 62 is arranged axially parallel to the guide member 3, with the spacing between two adjacent second guide members 62 gradually increasing along the air inlet direction. The uneven arrangement of the first and second guide members 61, 62 ensures a uniform airflow from the air outlet 20 near the first air inlet 301 or the second air inlet 302, ensuring uniform airflow along the longitudinal direction of the hair dryer and enhancing the user's hair curling experience.

[0184] Of course, the present application is not limited to this. Only the first guide member 61 is set to ensure uniform air outlet along the longitudinal direction in the first state; or only the second guide member 62 is set to ensure uniform air outlet along the longitudinal direction in the second state. Both do not deviate from the design concept and purpose of the present application. Therefore, technical personnel in this field should understand that these technical solutions should all be within the scope of protection of the present application.

[0185] As shown in FIG. 42 to FIG. 54 , the present application also provides a hair dryer accessory 200 .

[0186] 42-43 , the hair dryer accessory 200 of this embodiment can be used for the hair dryer main body, and the hair dryer accessory can be a curling iron. Specifically, the hair dryer accessory 200 can include a hair cylinder 21 and an air guide 322 .

[0187] The wind tube 21 may be cylindrical, or at least part of the circumferential structure of the wind tube 21 may be arc-shaped. The wind tube 21 has an air inlet duct 211, an air inlet 212, and an air outlet 213. The air inlet 212 and the air outlet 213 are both connected to the air inlet duct 211. The air inlet 212 is located at one end of the wind tube 21 in the axial direction, and the air outlet 213 is provided on the side wall of the wind tube 21. The air outlet 213 may extend along the axial direction of the wind tube 21. In this way, when the air flows through the wind tube 21, the wind tube 21 can guide the airflow direction from the axial direction to the radial direction.

[0188] 50 and 51 , the air guide member 322 is sleeved on the outside of the wind tube 21, and the air guide member 322 and the outer wall of the wind tube 21 jointly define a first air outlet channel 210a and a second air outlet channel 210b. The first air outlet channel 210a and the second air outlet channel 210b are distributed along the circumference of the wind tube 21, and the first air outlet channel 210a is suitable for guiding the airflow to one side of the air outlet 213 along the circumference of the wind tube 21, and the second air outlet channel 210b is suitable for guiding the airflow to the other side of the air outlet 213 along the circumference of the wind tube 21, that is, the first air outlet channel 210a and the second air outlet channel 210b can guide the airflow in opposite directions for discharge.

[0189] When in use, the air duct 21 can be rotated relative to the air guide member 322 so that at least one of the first air outlet channel 210a and the second air outlet channel 210b is connected to the air outlet 213, that is, when the hair dryer accessory 200 is connected and fixed to the handle in use, the air guide member is fixedly connected to the end of the handle through other connecting members, and the air duct 21 can be rotated by the operating member to rotate relative to the air guide member to achieve a change in the wind direction of the air outlet; for example, by controlling the rotation of the air duct 21, only the first air outlet channel 210a and the air outlet 213 can be connected; or, only the second air outlet channel 210b and the air outlet 213 can be connected; or, the first air outlet channel 210a and the second air outlet channel 210b can be connected to the air outlet 213 at the same time, and when both the first air outlet channel 210a and the second air outlet channel 210b are connected to the air outlet 213, the opening degrees of the first air outlet channel 210a and the second air outlet channel 210b can be the same or different. In this way, the hair dryer accessory 200 can discharge air only from the air outlet 213 on any side of the circumference of the air duct 21, or it can discharge air from both sides of the air outlet 213 along the circumference of the air duct 21 at the same time, so that the air outlet mode of the hair dryer accessory 200 is diversified, and the user can choose the corresponding air outlet mode according to actual needs.

[0190] According to the hair dryer accessory 200 of the embodiment of the present application, the air guide 322 and the outer wall of the air cylinder 21 are used to jointly define the first air outlet channel 210a and the second air outlet channel 210b, and the air cylinder 21 can be rotated relative to the air guide 322 to make at least one of the first air outlet channel 210a and the second air outlet channel 210b connected to the air outlet 213, thereby having more air outlet methods. In this way, when the user uses the hair dryer main body with the hair dryer accessory 200 to groom his hair, the air outlet method can be flexibly adjusted to adapt to the user's needs of grooming different parts of the hair with different holding methods. The flexibility and convenience of use are higher, and the use needs can be better met.

[0191] In some embodiments, referring to Figures 42-45, the air guide 322 may include a connecting frame 221 and an air guide cover 222. The connecting frame 221 is rotatably connected to the air duct 21. For example, the connecting frame 221 may be annular and the connecting frame is arranged on the outside of the air duct 21 so that the air duct 21 can rotate. The air guide cover 222 is arranged opposite to the air outlet 213. The air guide cover 222 and the outer wall of the air duct 21 jointly define a first air outlet channel 210a and a second air outlet channel 210b. In addition, one of the air guide cover 222 and the air duct 21 is provided with an airflow cutoff structure 2223. When the air duct 21 rotates relative to the air guide 322, the airflow cutoff structure 2223 cooperates with the other of the air guide cover 222 and the air duct 21 to connect at least one of the first air outlet channel 210a and the second air outlet channel 210b to the air outlet 213.

[0192] For example, when the airflow cutoff structure 2223 is provided on the air guide cover 222, the airflow cutoff structure 2223 can be provided at a position of the air guide cover 222 corresponding to the intersection of the first air outlet channel 210a and the second air outlet channel 210b. Through such a setting, the airflow cutoff structure 2223 can be reused at the first air outlet channel 210a and the second air outlet channel 210b, so only one airflow cutoff structure 2223 needs to be provided. Such structural optimization reduces the number of airflow cutoff structures, which is conducive to cost reduction.

[0193] When the airflow cutoff structure 2223 is provided on the air duct 21, two airflow cutoff structures 2223 may be provided, one located on either side of the air outlet 213 along the circumference of the air duct 21. Through the cooperation of the airflow cutoff structure 2223, the air guide cover 222, and the air duct 21, at least one of the first air outlet channel 210a and the second air outlet channel 210b is kept unobstructed, and airflow can only flow out from the unobstructed air outlet channel (the first air outlet channel 210a or the second air outlet channel 210b). In this way, the on-off control structure of the first air outlet channel 210a and the second air outlet channel 210b is relatively simple and easy to implement.

[0194] In some embodiments, referring to Figures 48-51, the air guide cover 222 may include a first air guide section 2221 and a second air guide section 2222. The first air guide section 2221 and the second air guide section 2222 are sequentially connected along the circumference of the air cylinder 21. The first air guide section 2221 and the portion of the outer wall of the air cylinder 21 located on one side of the air outlet 213 jointly define a first air outlet channel 210a. The second air guide section 2222 and the portion of the outer wall of the air cylinder 21 located on the other side of the air outlet 213 jointly define a second air outlet channel 210b. The connection between the first air guide section 2221 and the second air guide section 2222 constitutes an airflow cutoff structure 2223. That is, in this embodiment, the airflow cutoff structure 2223 is provided on the air guide cover 222.

[0195] The air outlet 213 has transition contact surfaces 217 on either side of the circumference of the air cylinder 21, connecting the outer and inner surfaces of the air cylinder 21 via the transition contact surfaces 217. The airflow cutoff structure 2223 protrudes radially inwardly of the air cylinder 21 and is adapted to interfere with the transition contact surfaces 217 on either side of the air outlet 213 along the circumference of the air cylinder 21. In this way, when the air duct 21 rotates relative to the air guide member 322, the air flow cut-off structure 2223 is always between the transition contact surfaces 217 on both sides of the air outlet 213 along the circumference of the air duct 21, and when the air flow cut-off structure 2223 is always between the transition contact surfaces 217 on both sides of the air outlet 213 along the circumference of the air duct 21 and does not contact the transition contact surface 217 on either side, the first air outlet channel 210a and the second air outlet channel 210b are both connected to the air outlet 213, and when the air flow cut-off structure 2223 contacts the transition contact surface 217 on either side, only the first air outlet channel 210a or the second air outlet channel 210b is connected to the air outlet 213.

[0196] In some embodiments, the air duct 21 is adapted to rotate between a first position and a second position. In the first position, the airflow blocking structure 2223 abuts against a transition contact surface 217 on one side of the air outlet 213 along the circumference of the air duct 21, thereby connecting the air outlet 213 and the first air outlet channel 210a. In the second position, the airflow blocking structure 2223 abuts against a transition contact surface 217 on the other side of the air outlet 213 along the circumference of the air duct 21, thereby connecting the air outlet 213 and the second air outlet channel 210b. This simplifies the coordination between the air duct 21 and the air guide cover 222, making it easier to control the on / off switching of the first air outlet channel 210a and the second air outlet channel 210b.

[0197] In some embodiments, as shown in FIG51 , the airflow cutoff structure 2223 is adapted to seal with the transition contact surface 217 on either side of the air outlet 213 to improve the sealing performance of the contact portion between the airflow cutoff structure 2223 and the air duct 21 to prevent air leakage.

[0198] In some embodiments, referring to FIG50 , the airflow blocking structure 2223 is provided with a mounting groove 2224 extending axially along the air duct 21. The hair dryer accessory 200 may further include a seal 323, which may be a sealing strip. The seal 323 is embedded in the mounting groove 2224. When the airflow blocking structure 2223 abuts against the transition contact surface 217 on either side of the air outlet 213 along the circumference of the air duct 21, the seal 323 contacts the air duct 21. In this manner, the sealing engagement between the airflow blocking structure 2223 and the air duct 21 is relatively simple, easy to implement, and low in cost.

[0199] In some embodiments, in combination with Figures 47, 50 and 51, the transition contact surface 217 on either side of the air outlet 213 along the circumference of the wind tube 21 is an arc surface. On the one hand, compared with the two side walls of the air outlet 213 extending along the radial direction of the wind tube 21, the sharp corners in the first air outlet channel 210a and the second air outlet channel 210b can be reduced, thereby reducing the gas resistance; on the other hand, it is easier to form an extrusion fit between the seal 323 and the transition contact surface 217 to improve the sealing performance.

[0200] In some embodiments, referring to Figures 50 and 51 , the surfaces of the first air guide segment 2221 and the second air guide segment 2222 on the side facing the air duct 21 are both outwardly concave arc surfaces. This can better guide the airflow along the circumference of the air duct 21 and reduce airflow resistance. It should be noted that in this embodiment, as long as the inner surfaces of the first air guide segment 2221 and the second air guide segment 2222 are both outwardly concave arc surfaces, there is no specific limitation on the outer surface structure of the first air guide segment 2221 and the second air guide segment 2222.

[0201] Referring to Figures 50 and 51, in order to further reduce the airflow resistance of the first air outlet channel 210a and the second air outlet channel 210b, the portion of the seal 323 protruding from the mounting groove 2224 also forms an arc surface, and smoothly transitions with the inner surfaces of the first air guide section 2221 and the second air guide section 2222. In this way, the airflow loss can be further reduced.

[0202] In some embodiments, referring to Figures 50 and 51, the cross-sections of the first air guide segment 2221 and the second air guide segment 2222 are both arc-shaped, and the first air guide segment 2221 and the second air guide segment 2222 are symmetrical about the airflow cutoff structure 2223. At this time, the cross-section of the air guide cover 222 is an M-shaped structure with a concave middle part as a whole. In this way, the structure of the air guide cover 222 is relatively simple and easy to manufacture, and it is beneficial to reduce the weight of the air guide cover 222, save materials, and reduce costs.

[0203] In some embodiments, referring to Figures 50 and 51 , the flow areas of the first and second air outlet channels 210a, 210b gradually decrease along the circumference of the hair cylinder 21 and away from the air outlet 213. This helps increase the air flow rate. When a user uses a curling iron with the hair dryer attachment 200 to style their hair, the hair dryer attachment 200 can more easily attract the hair to its surface, thereby improving hair styling efficiency and quality.

[0204] In some embodiments, referring to Figures 44, 45, and 49, a plurality of guide ribs 2225 are provided on the side of either the first air guide section 2221 or the second air guide section 2222 facing the air duct 21. The plurality of guide ribs 2225 are arranged at intervals along the axial direction of the air duct 21. The provision of the guide ribs 2225 helps to better guide the direction of the airflow.

[0205] In some embodiments, referring to FIG49 , the guide ribs 2225 are perpendicular to the axial direction of the air duct 21, and / or the guide ribs 2225 are tilted relative to the axis of the air duct 21 toward the air inlet 212. For example, the plurality of guide ribs 2225 can be perpendicular to the axial direction of the air duct 21, or the plurality of guide ribs 2225 can be tilted relative to the axis of the air duct 21 toward the air inlet 212. Alternatively, some of the plurality of guide ribs 2225 are perpendicular to the axial direction of the air duct 21, while others are tilted relative to the axis of the air duct 21 toward the air inlet 212. The extension direction of each guide rib 2225 can be appropriately set according to actual needs to meet the diversion requirements of different locations.

[0206] In some embodiments, referring to FIG. 49 , the spacing between any two adjacent guide ribs 2225 is the same, that is, the guide ribs 2225 at various locations along the axial direction of the air duct 21 are arranged at the same density, which facilitates processing.

[0207] Alternatively, in other alternative embodiments, the arrangement density of the guide ribs 2225 is increased along the axial direction of the wind tube 21 and close to the air inlet 212. Since the wind force is stronger near the air inlet 212, the arrangement density of the guide ribs 2225 near the air inlet 212 is increased, while the arrangement density of the guide ribs 2225 away from the air inlet 212 is adaptively reduced. This can make the arrangement density of the guide ribs 2225 more adapted to the wind force at different axial positions of the air inlet duct 211 along the wind tube 21, making the layout of the guide ribs 2225 more reasonable.

[0208] In some embodiments, the height of the guide ribs 2225 on the first air guiding section 2221 in the radial direction of the air cylinder 21 is less than the height of the first air outlet channel 210a, that is, the guide ribs 2225 on the first air guiding section 2221 can be spaced apart from the outer wall of the air cylinder 21. In this way, while guiding the direction of the airflow, the first air outlet channel 210a can be prevented from being divided into mutually isolated and smaller sub-channels, thereby reducing airflow loss.

[0209] The height of the guide ribs 2225 on the second air guide section 2222 in the radial direction of the air duct 21 is less than the height of the second air outlet channel 210b. The guide ribs 2225 on the second air guide section 2222 can be spaced apart from the outer wall of the air duct 21. In this way, the airflow direction can be guided while preventing the second air outlet channel 210b from being divided into mutually isolated and smaller sub-channels, thereby reducing airflow loss.

[0210] In some embodiments, referring to Figures 42-45 and Figures 48-50, the outer surface of the first air guide section 2221 and the outer surface of the second air guide section 2222 are provided with a plurality of reinforcing ribs 2226. The plurality of reinforcing ribs 2226 extend along the axial direction of the wind tube 21 and are arranged at intervals along the circumference of the wind tube 21. In this way, the structural strength of the wind guide cover 222 can be increased to prevent the wind guide cover 222 from deformation.

[0211] In some embodiments, referring to Figures 42-45 and 48-50, the outer surfaces of the first air-guiding section 2221 and the second air-guiding section 2222 are each provided with a plurality of guide teeth 2227. The guide teeth 2227 on the first air-guiding section 2221 are first guide teeth 2227, while the guide teeth 2227 on the second air-guiding section 2222 are second guide teeth 2227. Both the first guide teeth 2227 and the second guide teeth 2227 extend circumferentially along the hair cylinder 21. Furthermore, the plurality of first guide teeth 2227 are spaced apart along the axial direction of the hair cylinder 21, while the plurality of second guide teeth 2227 are spaced apart along the axial direction of the hair cylinder 21. Thus, when a user is styling their hair, the guide teeth 2227 help to straighten their hair.

[0212] In some embodiments, referring to Figures 42-45 and 48-50, the guide teeth 2227 on the first air guide segment 2221 are located on the side of the reinforcement ribs 2226 on the first air guide segment 2221 that is away from the airflow cutoff structure 2223. Furthermore, one end of the guide teeth 2227 on the first air guide segment 2221 is connected to the reinforcement rib 2226 on the first air guide segment 2221 that is farthest from the airflow cutoff structure 2223. The guide teeth 2227 on the second air guide segment 2222 are located on the side of the reinforcement ribs 2226 on the second air guide segment 2222 that is away from the airflow cutoff structure 2223. Furthermore, one end of the guide teeth 2227 on the second air guide segment 2222 is connected to the reinforcement rib 2226 on the second air guide segment 2222 that is farthest from the airflow cutoff structure 2223. Connecting the reinforcement ribs 2226 and the guide teeth 2227 in this manner can further enhance the overall structural strength of the air guide cover 222.

[0213] In some embodiments, referring to Figure 48, there are two connecting frames 221, and the two connecting frames 221 are respectively located at the two ends of the air guide cover 222 along the axial direction, and the two ends of each reinforcing rib 2226 are respectively connected to the two connecting frames 221. In this way, the connection strength between the connecting frame 221 and the air guide cover 222 can be increased, thereby enhancing the structural stability of the air guide member 322.

[0214] In some embodiments, referring to Figure 46, the inner wall of the air duct 21 has an air outlet arc surface 215, and the air outlet 213 is arranged on the air outlet arc surface 215. The air outlet arc surface 215 is symmetrical about the center line of the air outlet 213, that is, the air outlet 213 is arranged at the center position of the air outlet arc surface 215. This is conducive to the air flow in the air inlet duct 211 flowing to the air outlet 213, and can reduce the air flow resistance.

[0215] In some embodiments, referring to Figure 46, a plurality of dividing ribs 216 are provided in the air outlet 213, and the plurality of dividing ribs 216 are arranged at intervals along the axial direction of the wind tube 21. The plurality of dividing ribs 216 divide the air outlet 213 into a plurality of sub-air outlets 214. Compared with setting the air outlet 213 as a long strip, setting the dividing ribs 216 can increase the structural strength of the wind tube 21 near the air outlet 213.

[0216] In some embodiments, referring to FIG47 and FIG52-FIG54, the end of the air duct 21 opposite to the air inlet 212 in the axial direction has a connector, such as a connecting end plate 218, and a mounting portion 2181 is provided on the connector. The mounting portion 2181 can be formed as a mounting groove 2224, and a limiting member is provided in the mounting portion 2181, such as a limiting marble 219. The hair dryer accessory 200 can also include a limiting fitting, such as a limiting end cap 234. The limiting fitting is opposite to the connecting member inside and outside, and the limiting fitting is also fixedly connected to the air guide 322. For example, the limiting fitting can be fixedly connected to the connecting member of the air guide 322. For example, in one specific embodiment, the limiting end cap 234 has a limiting groove 3241. When the air duct 21 is in either the first position or the second position, the limiting ball 219 engages with the limiting groove 3241. Thus, when the air duct 21 is transferred to the first position or the second position, the air duct 21 is stably fixed in position and does not move. Thus, in this embodiment, a reliable method for fixing the air duct to rotate is provided.

[0217] For example, as shown in Figures 53 and 54, the connecting end plate 218 is provided with two mounting portions 2181, which are spaced 180 degrees apart. Each mounting portion 2181 is provided with a stopper 219. A stopper end cap 234 faces the connecting end plate 218 and can be engaged with the connector of the air guide 322. The limiting end cover 234 is provided with two limiting spaces, and the two limiting spaces correspond to the two mounting portions 2181 and the mounting portions 2181 one by one. Each limiting space includes a first limiting groove 3241, a limiting groove 3241, and a second limiting groove 3241. The first limiting groove 3241, the limiting groove 3241, and the second limiting groove 3241 are arranged at intervals along the circumference of the limiting end cover 234. The first limiting groove 3241 and the limiting groove 3241 determine the first position of the wind tube 21, and the second limiting groove The 3241 limiting groove 3241 determines the second position of the hair duct 21. When the hair duct 21 rotates to the first position, the two limiting marbles 219 are respectively inserted into the first limiting groove 3241 limiting groove 3241 of the two limiting spaces. When the hair duct 21 rotates to the second position, the two limiting marbles 219 are respectively inserted into the second limiting groove 3241 limiting groove 3241 of the two limiting spaces. In this way, when the hair duct 21 is transferred to the first position or the second position, it can be ensured that the hair duct 21 can stably maintain a fixed position without moving.

[0218] In some embodiments, referring to Figures 52 and 53 , the connecting end plate 218 is further provided with a drive connection portion 182, the limiting end cap 234 has a clearance hole 2342, and the drive connection portion 182 is opposite the clearance hole 2342. The hair dryer accessory 200 may further include a rotary drive member 235. Specifically, the rotary drive member 235 is disposed through the clearance hole 2342 and connected to the drive connection portion 182. Thus, the rotary drive member 235 can drive the air duct 21 to rotate, resulting in a relatively simple overall structure and ease of assembly.

[0219] For example, the driving connection part 182 can be a connection slot, and there are multiple connection slots. The connection slots are open toward one side of the limit end cover 234. The limit end cover 234 has an avoidance perforation 2342. The projections of the multiple connection slots in the reference plane are all within the projection of the avoidance perforation 2342 in the reference plane. The reference plane is perpendicular to the axial direction of the hair duct 21. The rotating drive member 235 has multiple plug-in protrusions 251. The plug-in protrusions 251 correspond one-to-one to the connection slots. After the plug-in protrusions 251 are inserted into the connection slots, the connecting end plate 218 and the rotating drive member 235 form a circumferential limit. At this time, the rotating drive member 235 can drive the hair duct 21 to rotate, thereby controlling the air outlet direction of the blowing device accessory 200.

[0220] In some embodiments, the hair dryer accessory 200 further includes a mounting bracket 326, which is located at the end of the air inlet 212 of the air duct 21. The mounting bracket 326 is rotatably coupled to the air duct 21. Furthermore, the mounting bracket 326 is fixedly connected to the connecting piece of the air guide 322 and can be connected to the handle of the hair dryer body. This further ensures the stability of the air duct 21 during rotation.

[0221] The following describes the main body of the blowing device according to the second embodiment of the present application.

[0222] The main body of the hair dryer of this embodiment includes a handle and the hair dryer accessory 200 in the above embodiment. The air inlet 212 of the hair dryer accessory 200 can be connected to the handle. An air flow driving device is provided in the handle. The air flow driving device drives the air flow from the air inlet into the air inlet duct 211.

[0223] According to the hair dryer main body of the embodiment of the present application, by setting the hair dryer accessory 200 in the above embodiment, the air outlet mode can be flexibly adjusted to adapt to the user's needs for caring for different parts of the hair with different holding methods. It has higher flexibility and convenience in use and can better meet the use needs.

[0224] As shown in Figures 55 to 62, the present application provides a hair dryer accessory 3100.

[0225] 55 and 56 , the blower attachment 3100 provided in the embodiment of the present application includes a frame 3110 and an air outlet plate 3120, wherein the frame is an axisymmetric structure, one end of the frame 3110 has an air flow inlet 3112, the frame 3110 is surrounded to form an air flow cavity 3111 connected to the air flow inlet 3112, and the end of the frame 3110 having the air flow inlet 3112 can be connected to the blower so that the air flow with a certain amount of heat energy provided by the blower enters the air flow cavity 3111 through the air flow inlet 3112; the frame 3110 has at least two groups of air outlet groups spaced apart along the circumference. 3113, the air outlet group 3113 includes at least one air outlet 31131; the air outlet plate 3120 is arranged around the outer periphery of the frame 3110, and the air outlet plate 3120 has an air outlet hole group 3130. The air outlet hole group 3130 includes at least two air outlet holes 3131. The at least two air outlet holes 3131 are arranged at intervals, and one air outlet 31131 on the frame 3110 corresponds to at least one air outlet hole 3131. In this way, the airflow entering the airflow cavity 3111 is discharged from each air outlet 31131 through the corresponding air outlet hole 3131, so that the airflow acts on the hair to style the hair.

[0226] For example, as shown in Figures 55 and 56, at least two air outlet holes 3131 are arranged at least at intervals along the circumference of the air outlet plate 3120, so that one air outlet 31131 corresponds to at least one air outlet hole 3131, wherein two adjacent air outlet holes 3131 can be arranged at intervals, end to end, or at least partially overlap in the circumferential direction, so that the continuity of the airflow in the circumferential direction of the air outlet plate 3120 can be improved, thereby improving the stability of automatic hair suction.

[0227] Among them, the hair drying device accessory 3100 provided in the embodiment of the present application adopts the principle of the Coanda effect. The air flow enters the air flow cavity 3111 from the air flow inlet 3112 at one end of the skeleton 3110, and is discharged in sequence through the air outlet 31131 and the corresponding air outlet hole 3131. In this way, the air flow is distributed along the circumference of the air outlet plate 3120, so that the hair is automatically adsorbed on the surface of the air outlet plate 3120 and wrapped around the outer wall surface of the air outlet plate 3120 along the direction of the air flow, and the hair is styled by the air flow acting on the hair.

[0228] It should be noted that the Coanda effect, also known as the wall adhesion effect, describes a phenomenon in which a fluid (water or air) deviates from its original direction of motion and rubs against a protruding surface, slowing its velocity. As long as the curvature of the surface is not too great, this slowed flow rate, according to the Bernoulli principle in fluid mechanics, causes the fluid to be adsorbed and flow along the surface. Therefore, in this embodiment of the present application, the airflow discharged from the air outlet 3131 flows along the surface of the air outlet plate 3120. In this way, the hair, under the influence of the airflow, automatically wraps around the air outlet plate 3120 in the direction of the airflow, thereby achieving automatic hair suction and curling, eliminating the need for manual curling.

[0229] In addition, in the embodiment of the present application, by making one air outlet 31131 correspond to at least one air outlet hole 3131, the airflow discharged through the air outlet 31131 is discharged through the first air outlet hole 3131a, and there will be no problem of airflow being unsealed and causing disorder.

[0230] For example, as shown in Figures 55 and 56, the skeleton 3110 can be surrounded to form an airflow cavity 3111 with a circular cross-section, and the airflow inlet 3112 is, for example, arranged at the bottom end of the skeleton 3110, and the air outlet plate 3120 is surrounded on the outer peripheral side of the skeleton 3110. In this way, the air outlet plate 3120 also forms a cylindrical structure with a circular cross-section to improve the smoothness of the airflow flowing along the outer wall of the air outlet plate 3120.

[0231] In some embodiments, the air outlet plate 3120 and the air outlet holes 3131 on the air outlet plate 3120 can be formed into an integrated structure using an integrated molding process such as injection molding, casting, and die casting. In this way, the processing process can be reduced, thereby reducing the process cost and achieving a good sealing effect.

[0232] It can be seen that the blower attachment 3100 provided in the embodiment of the present application is provided with an axially symmetrical skeleton 3110 and an air outlet plate 3120 arranged around the outer periphery of the skeleton 3110. The skeleton 3110 is provided with an air flow cavity 3111, and one end of the skeleton 3110 is provided with an air flow inlet 3112 connected to the air flow cavity 3111. At least two groups of air outlet groups 3113 arranged at intervals are provided on the skeleton 3110 along the circumferential direction. The air outlet group 3113 includes at least one air outlet 31131, and the air outlet plate 3120 is provided with at least one air outlet 31131. 20 is provided with an air outlet group 3130, the air outlet group 3130 includes at least two air outlets 3131, at least two air outlets 31131 are arranged at intervals, and one air outlet 31131 on the frame 3110 corresponds to at least one air outlet 3131. In this way, on the one hand, the air flow generated by the blowing device enters the air flow cavity 3111 through the air flow inlet 3112, and the air flow entering the air flow cavity 3111 is then passed through the air outlets 31131 on the circumference of the frame 3110 and the air outlets 31131 corresponding to the air outlets 31131. The airflow for styling the hair is discharged from the air outlet holes 3131, and the airflow for styling the hair is discharged from different positions of the circumference of the air outlet plate 3120, so that the airflow for styling the hair is arranged along the circumference of the air outlet plate 3120. The hair is wound around the air outlet plate 3120 through a strong circumferential adsorption force, and there is no need to manually wind the hair around the hair-drying device attachment 3100, which is simple to operate and improves the user experience. On the other hand, the air outlet area of ​​the air outlet holes 3131 is larger than that of the air outlet holes 3131 when the edge of the air outlet plate 3120 is used as the air outlet hole 3120. The air outlet area of ​​31 is larger, especially the air outlet holes 3131 can overlap or partially overlap in the circumferential direction, and the air outlet holes 3131 can be two rows or more than two rows, which increases the air outlet volume of the blowing device accessories; on the other hand, the air outlet holes 3131 and the air outlet plate 3120 are used as an integrated structure, which has a better sealing effect, can make the air flow flow along the set flow channel, has a better diversion effect, and is easy to install, reducing the vibration and wind noise between the structural parts. The overall structure is tight, the mechanical strength is stable, and it is resistant to falling or dropping.

[0233] In addition, the hair dryer accessory 3100 provided in the embodiment of the present application directly acts on the hair through the air outlet 3131, and uses the air outlet to curl the hair. There is no need to heat the air outlet plate 3120 to an excessively high temperature, which reduces damage to the hair and avoids scalding the user.

[0234] In some embodiments, the air outlet plate 3120 can be an integral structure, that is, the air outlet plate 3120 is an integral structure formed into a cylindrical shape, and at least two air outlet holes 3131 are arranged at least at intervals along the circumference of the air outlet plate 3120. Of course, the air outlet plate 3120 can also be provided with multiple air outlet holes 3131 at intervals in the axial direction, as long as a continuous airflow can be formed along the circumference of the air outlet holes 3131 to facilitate automatic hair suction and curling of the hair.

[0235] In other embodiments, as shown in Figure 56, the air outlet plate 3120 is not an integral structure, and there are multiple air outlet plates 3120. The multiple air outlet plates 3120 are connected in sequence along the circumference of the skeleton 3110 to form an annular structure surrounding the outer periphery of the skeleton 3110. It can be understood that by setting the number of air outlet plates 3120 to at least two, the air outlet holes 3131 are formed on each air outlet plate 3120 and then assembled. Compared with processing the air outlet holes 3131 on an annular integral air outlet plate 3120, the processing difficulty can be reduced and the overall assembly efficiency of the blowing device accessories can be improved.

[0236] When there are multiple air outlet plates 3120, the air outlet plates 3120 can be a flat plate structure or an arc plate. The cross-sectional shape of the arc plate can be a circular arc, an elliptical arc, etc. The specific adaptive design can be carried out according to actual needs and is not limited here.

[0237] For example, in Figure 56, the air outlet plate 3120 is an arc-shaped plate, and there are 12 air outlet plates 3120. The 12 arc-shaped plates are connected in sequence along the circumference of the skeleton 3110 to form a cylindrical structure with a circular cross-section, and are arranged around the outer side of the skeleton 3110, so that each air outlet 31131 on the skeleton 3110 has a corresponding air outlet hole 3131, thereby forming a continuous airflow discharged to the outside of the air outlet plate 3120, so as to curl the hair wrapped on the air outlet plate 3120 to improve the styling effect.

[0238] In some embodiments, the air outlet holes 3131 on the air outlet plate 3120 are connected end to end or at least partially overlap in the axial extension direction, wherein the axial direction of the air outlet plate 3120 is consistent with the axial direction of the skeleton 3110. In this way, the air outlet area of ​​the air outlet plate 3120 in the axial extension direction can be concentrated, thereby increasing the concentration of hair in the axial extension direction of the air outlet plate 3120, thereby improving the efficiency and effect of hair styling.

[0239] Exemplarily, the air outlet plate 3120 has a plurality of air outlet holes 3131 along the axial direction, and the plurality of air outlet holes 3131 along the axial direction can be located on the same straight line and connected end to end or at least partially overlap, so that the plurality of air outlet holes 3131 form a larger air outlet hole to improve the concentration of the air outlet, thereby increasing the amount of adsorbed air; or, among the plurality of air outlet holes 3131 along the axial direction, two adjacent air outlet holes 3131 are staggered with each other in the circumferential direction of the air outlet plate 3120, but connected end to end or at least partially overlap in the axial direction, for example, the bottom end of one of the two adjacent air outlet holes 3131 and the top end of the adjacent air outlet hole 3131 are located at the same height in the axial direction of the air outlet plate 3120, or have overlapping areas in the axial direction of the air outlet plate 3120, so that the continuity of the air outlet in the axial direction can be improved, and the amount of air wound around the air outlet plate 3120 can be increased.

[0240] In some embodiments, at least two rows of air outlet holes 3131 are provided in the circumferential direction of the air outlet plate 3120, wherein the air outlet directions of the air outlet holes 3131 in two adjacent rows can be the same or opposite. When the air outlet directions of the air outlet holes 3131 in two adjacent rows are the same, a complete airflow can be formed in the circumferential direction of the air outlet plate, and the air outlet area is concentrated, which can effectively guide the adsorbed hair, so that the hair tips can effectively move along the circumferential direction of the hair-drying device attachment, thereby increasing the amount of adsorbed hair grabbed, thereby improving the efficiency of hair styling; and when the air outlet directions of the air outlet holes 3131 in two adjacent rows are opposite, different air outlet directions can be switched to meet different curling needs.

[0241] In order to further improve the utilization efficiency of the Coanda effect in the accessory of the hair-drying device, in the embodiment of the present application, please refer to Figures 57 and 58, the air outlet 3131 forms a first guide angle A1 between the extension direction of the air outlet plate 3120 and the air outlet direction of the corresponding air outlet 31131 on the skeleton 3110, so that the air outlet 3131 guides the airflow discharged from the air outlet 31131 to flow along the surface of the air outlet plate 3120. In this way, the fit of the airflow flowing along the surface of the air outlet plate 3120 can be improved, so that the adsorbed hair forms curls along the circumferential contour of the hair-drying device accessory 3100; in addition, the adsorption stability of the hair automatically adsorbed to the surface of the air outlet plate 3120 is improved.

[0242] In some embodiments, the angle range of the first guide angle A1 is 0° to 45°. Since the fluid always flows in one direction, if the angle of the first guide angle A1 is too large, it will cause the hair to be wrapped around the air outlet plate 3120 with a large winding gap and a small amount of adsorption on the hair. Therefore, by limiting the first guide angle to an angle range of 0° to 45°, it is convenient to guide the airflow, thereby further improving the uniformity of the adsorption of the hair by the hair-drying device attachment, increasing the amount of adsorption on the hair, and the hair can be wrapped evenly around the surface of the hair-drying device attachment.

[0243] Exemplarily, the angle of the first guide angle A1 can be any angle between 0° and 45°, among which the preferred angles are 5°, 6°, 7°, 8°, 9°, 10°, 15°, 20°, 30°, 45°, etc. As long as the winding seal and hair adsorption after the hair is rolled can be guaranteed, there is no limitation here; when the first guide angle A1 is large, it can also be used to smooth out frizzy hair, generate a force to push short hair away from the outer wall of the air outlet plate, and hide the ends of the short hair into the longer hair.

[0244] In addition, in some embodiments, please continue to refer to Figure 58, the air outlet 3131 has a guide channel 3140 connected to the air outlet 3131 at one end of the outer wall of the air outlet plate 3120, and the extension path of the guide channel 3140 is arranged tangent to the outer wall of the air outlet plate 3120. It can be understood that the guide channel 3140 can further guide the airflow discharged from the air outlet 3131. For example, according to the Coanda effect, the airflow discharged from the air outlet 3131 can be guided to flow along the outer wall of the air outlet plate 3120 through the guide channel 3140, ensuring that the discharged airflow can utilize the wall attachment effect to allow the hair to be adsorbed on the circumference of the hair-drying device accessory, and the discharged airflows will not interfere with each other, thereby ensuring the smoothness of automatic adsorption of the hair.

[0245] Among them, there is a second guide angle A2 between the extension direction of the guide channel 3140 and the extension direction of the air outlet 3131, so as to guide the airflow discharged from the air outlet 3131 to flow along the surface of the air outlet plate 3120, so as to improve the winding effect of automatically absorbing hair and winding around the air outlet plate 3120 and ensure the amount of hair wound around the air outlet plate 3120, thereby improving the hair styling effect.

[0246] Exemplarily, the second guide angle A2 is 0° to 45°, and the angle of the second guide angle A2 can be any angle between 0° and 45°, wherein the preferred angle of the second guide angle A2 is 5°, 6°, 7°, 8°, 9°, 10°, 15°, 20°, 30°, 45°, etc., as long as the airflow discharged to the outer wall of the air outlet plate 3120 can be tangent to the outer wall of the air outlet plate 3120. In this way, the airflow can be guided, and the uniformity of the adsorption of the hair by the hair-drying device attachment can be further improved, the amount of adsorption of the hair can be increased, and the hair can be smoothly wrapped around the surface of the hair-drying device attachment, thereby improving the hair styling effect; further, when the second guide angle A2 is large, it can also be used to smooth out frizzy hair, generate a force to push short hair away from the outer wall of the air outlet plate, and hide the ends of the short hair into the longer hair.

[0247] In order to further improve the hair styling effect, in some embodiments, the air outlet plate 3120 is made of a material with good thermal conductivity. The material of the air outlet plate 3120 is, for example, a semiconductor thermal sensitive material with a certain temperature sensitivity. In this way, the air outlet plate 3120 can conduct heat. When curling the hair, the airflow discharged from the air outlet 3131 not only styles the hair, but the air outlet plate 3120 with a certain temperature can also heat the hair for styling. The temperature of the air outlet plate 3120 can maintain the temperature uniformity during hair styling, thereby improving the hair styling effect.

[0248] In some embodiments, please refer to Figure 55, at least two air outlet holes 3131 are arranged in sequence and staggered along the circumference of the air outlet plate 3120. For example, at least two air outlet holes 3131 are arranged in sequence and staggered along the circumference of the air outlet plate 3120 in the first direction. That is to say, the heights of two adjacent air outlet holes 3131 in the circumferential direction are different in the first direction, wherein the first direction is, for example, the same as the axial direction of the skeleton 3110.

[0249] In the embodiment of the present application, at least two air outlet holes 3131 are staggered in sequence at least in the circumferential direction of the air outlet plate 3120. In this way, a complete airflow can be formed in the circumferential direction of the air outlet plate 3120, and the air outlet area is concentrated, which can effectively guide the adsorbed hair, so that the hair tips can effectively move along the circumferential direction of the hair-drying device attachment, thereby increasing the amount of adsorbed hair grabbed, thereby improving the efficiency of hair styling.

[0250] In some embodiments, at least two air outlet plates 3120 are arranged in sequence along the axial direction of the skeleton 3110, and a spacer is provided between the two adjacent air outlet plates 3120, and the spacer is arranged around the outer peripheral side of the skeleton 3110 and connected to the skeleton 3110; in this way, the spacer is connected to the skeleton 3110, and the spacer is connected between the two adjacent air outlet plates in the axial direction of the skeleton 3110 to reduce the installation difficulty of the two adjacent air outlet plates 3120. In addition, the connection strength between the two adjacent air outlet plates 3120 can also be improved, thereby improving the connection reliability of the two adjacent air outlet plates 3120.

[0251] In some embodiments, the spacer includes but is not limited to having heat conduction function, heating function, display function, indication function, etc.

[0252] As an example, the spacer is provided with air outlet holes, which can improve the continuity of air outlet, thereby improving the adsorption effect and styling effect on the hair.

[0253] As another example, a display area may be provided on the spacer, and the display area is configured to display the time and styling status of the hair styling, so that the user can intuitively know the time used for the current hair styling, the remaining time and the styling status, etc., without having to record the time, thereby improving the user experience.

[0254] As another example, the spacer may be an indicator light ring, that is, the indicator light ring may present different light colors so as to intuitively remind the user of the current hair styling time and styling status.

[0255] As another example, the spacer can also be a spacer heating element, that is, the spacer has the function of spacing two adjacent air outlet plates 3120 in the axial direction, and also has a heating function, so that the spacer heating element can generate heat under conditions such as power supply to style the hair and improve the effect of hair styling.

[0256] As another example, the spacer can also be a heat-conducting spacer made of a heat-conducting material, that is, the spacer has the function of spacing two adjacent air outlet plates 3120 in the axial direction, and can also transfer heat, so as to transfer the heat of the air outlet plate 3120 or the skeleton 3110 to the hair, so as to enhance the effect of hair styling.

[0257] In some embodiments, as shown in Figure 56, the air outlet hole group 3130 includes a first air outlet hole group 3130a, and each air outlet plate 3120 is provided with at least one first air outlet hole group 3130a, and the first air outlet hole group 3130a includes at least one first air outlet hole 3131a. In this way, the outer peripheral side of the skeleton 3110 has multiple first air outlet hole groups 3130a along the circumferential direction, and the multiple first air outlet hole groups 3130a are arranged at intervals along the circumference of the skeleton 3110. In this way, the airflow discharged through the first air outlet holes 3131a in each first air outlet hole group 3130a flows along the circumference of the air outlet plate 3120, so that the hair can be automatically wrapped around the air outlet plate 3120 under the action of the airflow, thereby improving the reliability of automatic adsorption and winding.

[0258] In some embodiments, please refer to Figures 56 and 59, each air outlet group 3113 includes at least two air outlets 31131, at least two air outlets 31131 are arranged at intervals along the first direction on the skeleton 3110, and two adjacent air outlets 31131 are staggered in the second direction; each first air outlet group 3130a includes at least two first air outlets 3131a, at least two first air outlets 3131a are arranged at intervals along the first direction on the corresponding air outlet plate 3120, and two adjacent first air outlets 3131a are staggered in the second direction. Setting; wherein, the second direction and the first direction are staggered with each other, the first direction is, for example, the axial direction of the skeleton 3110, and the second direction is, for example, the circumferential direction of the skeleton 3110, and by making the two adjacent first air outlet holes 3131a on each air outlet plate 3120 spaced apart in the first direction and staggered in the second direction, in this way, the uniformity and integrity of the airflow distribution on the air outlet plate 3120 can be improved, the circulation effect of the airflow is improved, the overall distribution of the airflow is strengthened, the local temperature imbalance of the accessories of the blowing device is avoided, and the controllability of the overall airflow of the accessories of the blowing device is enhanced.

[0259] In order to use the same hair-drying device attachment 3100 to perform curling on the hair in different directions, in some embodiments, the air outlet group 3130 also includes a second air outlet group (not shown in the figure), and each air outlet plate 3120 has a second air outlet group. Along the circumference of the skeleton 3110, the first air outlet group 3130a and the second air outlet group on the same air outlet plate 3120 are arranged at intervals; in this way, multiple first air outlet groups 3130a and multiple second air outlet groups are alternately arranged at intervals along the circumference of the skeleton 3110, wherein the second air outlet group includes at least one second air outlet 3131, and the air outlet direction of the second air outlet 3131 is opposite to the air outlet direction of the first air outlet 3131a; and the first air outlet group 3130a and the second air outlet group can be selectively opened and closed so that the air outlet 31131 is connected to one of the first air outlet group 3130a and the second air outlet group.

[0260] It can be understood that by setting up the first air outlet group 3130a and the second air outlet group with the opposite wind direction, when the user styles the hair, he can select the wind direction according to actual needs to form styling effects with different winding directions.

[0261] In some embodiments, the blowing device accessory 3100 includes a seal (not shown in the figure), which is constructed to be movably arranged between the frame 3110 and at least two air outlet plates 3120, and to switch between a first position and a second position so that the seal opens one of the first air outlet group 3130a and the second air outlet group, and closes the other of the first air outlet group 3130a and the second air outlet group.

[0262] Among them, the seal is, for example, a sealing plate. By moving the position of the seal, the first air outlet group 3130a and the second air outlet group can be opened and closed to meet the user's different styling requirements, achieve rapid switching of the curling direction, and enhance the user's experience.

[0263] Exemplarily, the seal can move along the circumference of the skeleton 3110 between the skeleton 3110 and the air outlet plate 3120. There can be multiple seals, and the number of seals is the same as the number of first air outlet holes 3131a and the number of second air outlet holes 3131. One seal corresponds to one first air outlet hole 3131a or one second air outlet hole 3131. Multiple seals can be connected to each other. In this way, by starting one seal, all other seals can be driven to move together, so that the seal can be rotated to the first air outlet hole or the second air outlet hole 3131 to realize the opening and closing of the first air outlet hole 3131a and the second air outlet hole 3131.

[0264] In order to further facilitate user operation, in some embodiments, please refer to Figures 55, 56, 59 and 60, the hair dryer accessory 3100 also includes a switch 3150, and the switch 3150 is connected to the sealing member. The switch 3150 is constructed to drive the sealing member to switch between the first position and the second position. That is, the user can operate the switch 3150 to drive the sealing member to switch between the first position and the second position through the switch 3150, thereby realizing the opening and closing of the first air outlet and the second air outlet 3131, so as to meet the different styling requirements of the user and realize the rapid switching of the curling direction, and the switching method is simple.

[0265] In some embodiments, the switch member 3150 is arranged at one end of the skeleton 3110 away from the air flow inlet 3112 and is rotatably connected to the skeleton 3110, and the switch member 3150 is connected to at least one sealing member. In this way, when a knob force is applied to the switch member 3150, the switch member 3150 can drive the sealing member to rotate relative to the skeleton 3110, thereby causing the dynamic sealing member to switch between the first position and the second position to realize the opening and closing of the first air outlet 3131a and the second air outlet 3131. In this way, the switching structure of the airflow outlet direction is simple and easy to implement.

[0266] Exemplarily, the switch member 3150 may be a switch knob, which can be rotated to switch between two opposite airflow directions, thereby improving the user's curly hair styling options and simplifying operation.

[0267] In other embodiments, the blowing device accessory 3100 may also not be provided with a seal, and the skeleton 3110 may be set to rotate relative to the air outlet plate 3120, that is, the skeleton 3110 can rotate around its own axis to rotate between a first position and a second position in the circumferential direction relative to the air outlet plate 3120, so that the air outlet group 3113 on the skeleton 3110 can be selectively connected to one of the first air outlet group 3130a and the second air outlet group.

[0268] In an embodiment of the present application, the skeleton 3110 is rotated to switch the opening and closing of the first air outlet group 3130a and the second air outlet group. The rotation area of ​​the skeleton 3110 is small and the friction generated is small, making the rotation easier and having little impact on related structures such as the external air outlet plate 3120.

[0269] In some embodiments, the switch member 3150 is disposed at one end of the skeleton 3110 away from the air flow inlet 3112 and is connected to the skeleton 3110. The switch member 3150 is configured to drive the skeleton 3110 to rotate around its own axis under the action of force, so that the skeleton 3110 switches between the first position and the second position relative to the air outlet plate 3120, so as to facilitate driving the skeleton 3110 to rotate by the switch member 3150 to realize the opening and closing of the first air outlet group 3130a and the second air outlet group. The operation is simple and easy to implement.

[0270] In some embodiments, at least two air outlet plates 3120 are respectively detachably connected to the skeleton 3110, and no mechanical connection is required between two adjacent air outlet plates 3120, so that each air outlet plate 3120 is installed on the skeleton 3110. In this way, the difficulty of connecting two adjacent air outlet plates 3120 can be reduced, and the strength of each air outlet plate 3120 can be improved. By making the air outlet plates 3120 detachably connected to the skeleton 3110, it is convenient to replace, repair and maintain various parts of the hair dryer accessory 3100. When some parts of the hair dryer accessory need to be replaced and maintained, only the damaged parts need to be replaced, thereby reducing the disassembly process.

[0271] In some embodiments, as shown in Figure 56, each air outlet plate 3120 has a first clamping portion 3122, and the skeleton 3110 has a second clamping portion 3114 that matches the first clamping portion 3122. The first clamping portion 3122 is clamped with the second clamping portion 3114. By connecting the air outlet plate 3120 and the skeleton 3110 by clamping, the difficulty of disassembly and assembly is reduced, thereby reducing costs.

[0272] Exemplarily, the first engaging portion 3122 is one of a buckle and a hole, and the second engaging portion 3114 is the other of the buckle and the hole. For example, the first engaging portion 3122 is a buckle, and the second engaging portion 3114 is a slot or a hole. When the air outlet plate 3120 is mounted on the frame 3110, the buckle is engaged with the slot or hole. This simple engaging structure facilitates processing and increases production capacity, reduces overall maintenance costs for the blower device accessories, and improves maintenance convenience.

[0273] Among them, the first clamping portion 3122 is arranged on the side surface of the air outlet plate 3120 facing the frame 3110. When the air outlet plate 3120 is installed on the frame 3110, the first clamping portion 3122 is hidden inside the entire blowing device accessory 3100. In this way, it can prevent users from disassembling the air outlet plate 3120 at will. In addition, it also improves the assembly efficiency of the blowing device accessory 3100 and increases production capacity.

[0274] In order to further reduce the processing difficulty of the air outlet plate 3120, please refer to Figure 56, each air outlet plate 3120 includes at least two sub-air outlet plates 3121, and at least two sub-air outlet plates 3121 are detachably connected in sequence in the first direction. In this way, the volume of the air outlet plate 3120 is reduced, which is convenient for processing. For example, it can be processed on a small machine, saving the loading space of the entire blowing device accessories; in addition, by setting each air outlet plate 3120 as a plurality of independent sub-air outlet plates 3121, when maintenance is required, only the damaged part needs to be replaced; and when disassembling, only the sub-air outlet plate 3121 at the corresponding position can be disassembled, which is more convenient than the larger air outlet plate 3120.

[0275] In some embodiments, please refer to Figures 55, 56, 59 and 60. Along the first direction, a connecting member 3160 is further provided between two adjacent sub-air outlet plates 3121. The connecting member 3160 is arranged around the outer peripheral side of the skeleton 3110 and is connected to the skeleton 3110. The two adjacent sub-air outlet plates 3121 are respectively detachably connected to the connecting member 3160.

[0276] In an embodiment of the present application, a connecting member 3160 is provided to connect two adjacent sub-air outlet plates 3121 in the first direction through the connecting member 3160 to reduce the difficulty of installing the two adjacent sub-air outlet plates 3121. In addition, the connection strength between the two adjacent sub-air outlet plates 3121 can also be improved, thereby improving the connection reliability of the two adjacent sub-air outlet plates 3121.

[0277] In some embodiments, as shown in Figures 57, 58 and 62, the connecting member 3160 is a ring-shaped structure, and the connecting member 3160 is sleeved on the skeleton 3110. The two ends of the connecting member 3160 are respectively provided with a first plug-in portion 3161 on the end surface facing the two adjacent sub-air outlet plates 3121, and the two adjacent sub-air outlet plates 3121 are respectively provided with a second plug-in portion 31211 matching the first plug-in portion 3161. The first plug-in portion 3161 and the second plug-in portion 31211 are plugged into each other. On the one hand, the sub-air outlet plate 3121 and the connecting member The disassembly and assembly method between 3160 is simple, easier to implement and low-cost; on the other hand, after the sub-air outlet plate 3121 is connected to the connecting piece 3160, the first plug-in part 3161 and the second plug-in part 31211 are hidden between the sub-air outlet plate 3121 and the connecting piece 3160, which can avoid the problem of users disassembling the sub-air outlet plate 3121 at will; on the other hand, the sub-air outlet plate 3121 and the connecting piece 3160 are connected by plugging the first plug-in part 3161 and the second plug-in part 31211. The connection method is simple and the assembly efficiency is high, thereby improving the production capacity of the blowing device accessory 3100.

[0278] Exemplarily, the first plug-in portion 3161 is one of the plug-in protrusion and the plug-in slot, and the second plug-in portion 31211 is the other of the plug-in protrusion and the plug-in slot; for example, the first plug-in portion 3161 is a slot, and the second plug-in portion 31211 is a plug-in protrusion. The plug-in protrusion is directly plugged into the slot to realize the plug-in of the sub-air outlet plate 3121 and the connecting member 3160. The plug-in structure is firm and reliable, safe and reliable, reduces the safety hazards and instability factors of other connection methods, and enhances the overall safety of the hair dryer accessories.

[0279] Among them, as shown in Figures 60 to 62, when the connecting member 3160 is a circular ring structure, the outer diameter of the ring-shaped connecting member 3160 is larger than the outer diameter of the skeleton 3110, and the connecting member 3160 has a mounting protrusion 3162 on the side close to the skeleton 3110, and the skeleton 3110 has a mounting groove 3115 matching the mounting protrusion 3162, and the mounting protrusion 3162 is located in the mounting groove 3115 to realize the connection between the connecting member 3160 and the skeleton 3110.

[0280] When the switch component 3150 is installed on the end of the frame 3110 away from the air flow inlet 3112, the entire assembly and locking of the hair dryer accessory 3100 can be completed by locking the screws. When the hair dryer accessory 3100 needs to be disassembled, the locking screws are first removed to unlock the various components of the hair dryer accessory 3100, and then the hair dryer accessory 3100 can be disassembled.

[0281] It should be noted that the connecting member 3160 can be an integrated structure with the spacer, or a structure independent of each other. When the connecting member 3160 and the spacer are structures independent of each other, the connecting member 3160 can also be provided with air outlets, a display area, a heating function, a heat conduction function, a display area, an indicator ring light and other functions that are the same as those of the spacer, as well as other achievable functions, which are not listed here one by one.

[0282] A second aspect of an embodiment of the present application provides a hair drying device, comprising a device body and a hair drying device accessory as provided in the above embodiment, wherein the hair drying device accessory is configured to be connected to the device body.

[0283] The hair styling device includes at least one of a hair dryer and a multifunctional hair styling device.

[0284] The structure of the accessories of the blowing device has been introduced in the above embodiment and will not be repeated here.

[0285] The hair dryer attachment provided in the embodiment of the present application is provided with a frame and an air outlet plate arranged around the outer circumference of the frame. The frame forms an air flow cavity. An air flow inlet communicating with the air flow cavity is provided at one end of the frame, and at least two groups of air outlet groups spaced apart are provided on the frame along the circumference. The air outlet group includes at least one air outlet. An air outlet hole group is provided on the air outlet plate. The air outlet hole group includes at least two air outlet holes. The at least two air outlet holes are spaced apart, and one air outlet hole corresponds to one air outlet on the frame. In this way, the air flow generated by the hair dryer enters the air flow cavity through the air flow inlet. The air flow entering the air flow cavity is then discharged through the air outlets along the circumference of the frame and the air outlet holes corresponding to the air outlets. The air flow used for styling hair is discharged from different positions around the air outlet plate, so that the air flow for styling hair is arranged along the circumference of the air outlet plate. The hair is wrapped around the air outlet plate due to the strong circumferential adsorption force. There is no need to manually wrap the hair around the hair dryer attachment, which is simple to operate and improves the user experience.

[0286] As shown in Figures 63 to 69, the present application provides an accessory for a hair dryer.

[0287] It should be noted that the axial direction in this embodiment refers to the direction along the axis of the main body 410, i.e., the vertical direction in Figure 64; the circumferential direction refers to the direction along the circumference of the main body 410, i.e., the circumferential direction in Figure 69; and the radial direction refers to the diameter direction. The axial, circumferential, and radial directions of the main body 410 correspond to the axial, circumferential, and radial directions of the hair dryer accessory, respectively. Furthermore, this embodiment uses the hair dryer accessory for high-vault styling as an example for explanation; however, the hair dryer accessory in this embodiment can also be used for other hair styling applications.

[0288] As shown in Figures 63 to 69, the accessories of the blowing device of this embodiment mainly include a main body 410, a support member 420 and a sliding member 430, wherein the interior of the main body 410 of this embodiment is set as a hollow cavity as a whole, one end of which is set as an opening, and the port is set as an air flow inlet 4113, so that the air flow can enter the hollow interior of the main body 410 through the air flow inlet 4113, and a plurality of air outlet plates 4123 are provided on the circumferential side of the main body 410, and air outlet channels are formed between the air outlet plates 4123. In this way, the air flow in the hollow cavity of the main body 410 can be blown out through the air outlet channel, thereby realizing the effect of converting the air flow in the axial direction of the main body 410 into blowing out from the circumferential side.

[0289] As shown in Figures 64 and 68, the support member 420 of this embodiment is arranged on the circumferential side of the main body 410, and the support member 420 is fixedly connected to the outer side wall of the main body 410, and the support member 420 only covers a small part of the circumferential side of the main body 410, so that the support member 420 can play a certain supporting role. When in use, the user puts the support member 420 close to the scalp. Due to the support of the support member 420, a certain distance is formed between the main body 410 and the scalp, so that the support member 420 leaves a certain gap between the air outlet channel and the scalp. On the one hand, the airflow blown out of the air outlet channel can directly act on the hair at the roots to ensure the styling effect, and at the same time, it can avoid the hot air blown out of the air outlet channel directly acting on the scalp to cause overheating or even scald burns, thereby improving the safety of use. In addition, the support member 420 can also help the user distinguish the use direction to avoid the user's misoperation and putting other use surfaces close to the scalp to cause burns.

[0290] As shown in Figure 63, the sliding member 430 is arranged on the outer peripheral side of the main body 410. The sliding member 430 can move back and forth in a circumferential direction relative to the main body 410, so that the sliding member 430 can close part of the air outlet channel according to usage needs, so that the air outlet position, air outlet size, air outlet direction, etc. of the hair dryer accessories can be adjusted as needed to meet the different usage needs of users.

[0291] As shown in Figures 63 and 67, in order to achieve the connection and installation of the sliding member 430, the main body 410 of this embodiment includes a first support portion 413 and a second support portion 414, wherein the first support portion 413 and the second support portion 414 of this embodiment both adopt an annular structure and are respectively arranged at the axial ends of the air guide bracket 417, so that the air outlet channel is located between the first support portion 413 and the second support portion 414. At the same time, since the sliding member 430 plays the role of blocking the air outlet channel, the sliding member 430 is also arranged between the first support portion 413 and the second support portion 414. In this way, the first support portion 413 and the second support portion 414 can play a certain supporting and installing role for the sliding member 430, and can also limit the movement range and movement direction of the sliding member 430, so that the sliding member 430 can only rotate along the circumference of the main body 410, and the rotation range is other positions except those covered by the support member 420, so as to ensure that the sliding member 430 can rotate in the expected manner, thereby improving the reliability of the entire styling accessory.

[0292] As shown in Figures 65 and 69, the main body 410 of this embodiment includes a flow guide bracket 417. As a key component of the main body 410, the flow guide bracket 417 has a hollow cylindrical structure. Multiple ventilation slots are defined along the circumferential side surfaces of the flow guide bracket 417. These slots have a specific length, allowing for continuous airflow within the slots. This increases the airflow area, improves the airflow quality, and thus enhances the styling effect at the hair roots. The ventilation slots are arranged circumferentially and axially of the flow guide bracket 417, allowing airflow within the flow guide bracket 417 to be blown outward through the slots. The side of the ventilation slot is inclined to form a guide surface 4171, so that the guide surface 4171 is located upstream of the air outlet channel. When the airflow in the middle of the cylinder acts on the guide surface 4171 when passing through the ventilation slot, the guide surface 4171 of this embodiment adopts an inclined plane or an inclined arc surface structure, and its inclination direction is inclined to the tangent direction of the main body 410, so that when the airflow acts on the guide surface 4171, it switches from a radial direction to an inclined direction under the action of the guide surface 4171. At this time, the airflow is converted to a certain direction tangential to the main body 410 and then flows out. The outer surface of the flow bracket 417 is also set to an arc-shaped surface, so that the airflow is blown out from the air outlet channel roughly along the tangential direction under the shape of the main body 410, and the fluid forms a circular flow roughly along the circumference of the main body 410 after flowing out. In this way, the airflow guidance effect can be effectively achieved, and it is beneficial for the subsequent blown airflow to adhere to the circumferential surface of the main body 410, thereby effectively preventing the airflow from diffusing and generating turbulence, so that the airflow can act stably on the roots of the hair, so that the hair roots can stand up under the action of the airflow, thereby forming a high top of the head shape of the hair, so that the user can have a styling effect of head covering face.

[0293] In this embodiment, the guide bracket 417 is set to be cylindrical, so that the main body 410 is also formed into a cylindrical shape. This shape can facilitate the flow of air and the styling of hair during hair styling, and is also conducive to ensuring that the air flow is blown out in a circumferential direction. Of course, the shape of the guide bracket 417 and the main body 410 as a whole can also be adjusted as needed and can be set to other shapes such as an ellipse.

[0294] In this embodiment, the air outlet plates 4123 are arranged on the outer peripheral side of the guide bracket 417 and at the ventilation slot, so that the gap between the air outlet plates 4123 is located downstream of the air outlet channel, and the air flow blown out through the channel will act on the outer peripheral side of the air outlet plates 4123. Since the air outlet plates 4123 are arranged as inclined planes or curved surfaces facing the side of the channel, this embodiment is preferably arranged as curved surfaces, so that the air flow can act on the curved surface after passing through the ventilation slot, and then be blown out along the curved surface. The arrangement of the curved surface allows the air flow to continue to flow along the circumference of the main body 410 after being blown out of the air outlet channel, thus forming an arc-shaped airflow. The arc-shaped airflow can drive the nearby airflow to accelerate and form a small-scale negative pressure effect. Once the hair approaches the curved guide, the hair roots will be attracted to the curved airflow under the action of the wall attachment effect, thereby preventing the hair from drifting away, so that the blown arc-shaped airflow can act on the hair roots more directly, making it convenient for styling such as high skull tops.

[0295] This embodiment utilizes a snap-fit ​​and bolted connection method between the air outlet plate 4123 and the air guide bracket 417. Specifically, a snap-fit ​​structure is provided on the inner surface of the air outlet plate 4123, that is, the surface facing the interior of the main body 410. Correspondingly, a slot is provided on the air guide bracket 417. The snap-fit ​​engages within the slot to achieve the connection between the air outlet plate 4123 and the air guide bracket 417. Furthermore, this embodiment provides curved connecting sections at both ends of the air outlet plate 4123, each with mounting holes. Mounting holes are also provided on the end surface of the air guide bracket 417. Screws are inserted into the two mounting holes, thereby securing the air outlet plate 4123 to the air guide bracket 417. Of course, the connection method between the air outlet plate 4123 and the air guide bracket 417 can be adjusted as needed, and can utilize only one of the snap-fit ​​and bolted connection methods, or other connection methods.

[0296] In this embodiment, there are multiple air outlet channels, which are divided into two groups, namely the first air outlet channel 415 and the second air outlet channel 416. The settings of the two groups of air outlet channels are basically the same, and both are formed by the aforementioned air outlet plate 4123 and the guide bracket 417. The difference between the two lies in the different air outlet directions, that is, along the circumference of the main body 410, the air outlet directions of the first air outlet channel 415 and the second air outlet channel 416 are opposite. Taking the circumferential direction in Figure 69 as an example, the air outlet direction of the first air outlet channel 415 at the bottom is counterclockwise, while the air outlet direction of the second air outlet channel 416 at the top is clockwise. In this way, a hair dryer accessory can have two air outlet directions at the same time, so that the hair dryer accessory can adjust the air outlet direction according to the direction of the user's hair, thereby meeting different styling requirements.

[0297] Since two groups of air outlet channels with different air outlet directions are provided, the sliding member 430 of this embodiment can selectively block one of the first air outlet channel 415 and the second air outlet channel 416 when it rotates along the circumference of the main body 410. In this way, if the air outlet direction of the first air outlet channel 415 is required during use, the sliding member 430 can be rotated to block the second air outlet channel 416. If the air outlet direction of the second air outlet channel 416 is required, the sliding member 430 can be rotated to block the first air outlet channel 415. In this way, through the cooperation between the sliding member 430 and the two groups of air outlet channels, the hair dryer accessory can adjust the air outlet direction as needed, thereby meeting different needs and achieving the effect of improving the user experience. The sliding member 430 blocks the air outlet direction of the first air outlet channel 415 or the second air outlet channel 416, which can effectively avoid the collision of the airflows generated by the two air outlet channels and prevent the airflow from being turbulent and breaking up the hair.

[0298] Because support member 420 is provided between first support portion 413 and second support portion 414, i.e., on the side surface surrounding the air outlet channel, this embodiment utilizes two air outlet channels to blow air in a direction away from support member 420. Specifically, when support member 420 is close to the scalp, first air outlet channel 415 or second air outlet channel 416 discharges air toward the hair roots. This allows the airflow to act directly on the hair roots, thereby achieving a styling effect. Of course, the airflow direction of the air outlet channels can be adjusted as needed, as long as the airflow is directed toward the hair roots and achieves a styling effect at the hair roots.

[0299] In this embodiment, it is preferred that both the first air outlet channel 415 and the second air outlet channel 416 discharge air along a tangential direction of the main body 410, thereby ensuring that the blown airflow can flow as closely as possible along the circumference of the main body 410. Furthermore, the first air outlet channel 415 of this embodiment has a plurality of first air outlet slots, and similarly, the second air outlet channel 416 has a plurality of second air outlet slots. The first air outlet slots and the second air outlet slots are formed by the gaps between the air outlet plates 4123. Furthermore, the first air outlet slots and the second air outlet slots of this embodiment each occupy two circumferential areas of the main body 410, and the two areas do not intersect. That is, the first air outlet slots are adjacently disposed on the outer circumferential surface of the main body 410, and the second air outlet slots are adjacently disposed on the outer circumferential surface of the main body 410. In this way, the first air outlet slots are arranged in sequence along the circumference of the main body 410, and there is no second air outlet slot between them. Similarly, the second air outlet slots are arranged in sequence along the circumference of the main body 410, and there is no first air outlet slot between them. In this way, the first air outlet slot and the second air outlet slot respectively occupy two circumferential areas of the main body 410, that is, the upper and lower parts of the main body 410 in Figure 69 are respectively the areas where the two groups of air outlet channels are located. The two areas are both circumferentially continuous, and the two are independent of each other and do not intersect with each other. In this way, the sliding member 430 can unilaterally block one of the first air outlet channel 415 and the second air outlet channel 416, and there will be no situation where the first air outlet channel 415 needs to be opened but the sliding member 430 blocks part of the first air outlet channel 415, thereby ensuring the air outlet volume and air outlet effect of the two groups of air outlet channels, thereby increasing the styling area acting on the hair.

[0300] It should be noted that, in addition to being arranged circumferentially along the main body 410, the first air outlet slots can also be partially arranged axially along the main body 410, thereby allowing the first air outlet channel 415 to continuously extend a certain length along the axial direction of the main body 410. In this embodiment, the first air outlet channel 415 covers the entire axial length of the main body 410 as much as possible, thereby facilitating an increase in the air outlet area and ensuring the air outlet effect. The second air outlet slots and second air outlet channel 416 can also adopt the above arrangement, thereby ensuring that both sets of air outlet channels have a large air outlet area.

[0301] This embodiment is equipped with eight air outlet plates 4123, which are divided into two groups, forming a first air outlet channel 415 and a second air outlet channel 416, respectively. This results in four first air outlet channels 415 and four second air outlet channels 416, respectively. Furthermore, the first air outlet channels 415 and the second air outlet channels 416 are located on opposite sides of the main body 410 in the circumferential direction, resulting in an aesthetically pleasing overall structure. In this embodiment, the first air outlet channels 415 and the second air outlet channels 416 are preferably symmetrically arranged on opposite sides of the main body 410, resulting in a generally symmetrical overall structure for the hair dryer accessory. This not only improves the appearance, but also enhances the operating feel when the slider 430 slides circumferentially to switch positions. Of course, the number and position of the air outlet plates 4123, air outlet channels, and other structures can also be adjusted accordingly as needed.

[0302] As shown in Figure 64, the support member 420 of this embodiment adopts a strip-like structure, extending along the axial direction of the main body 410 and covering the entire axial length of the main body 410 as much as possible. The support member 420 protrudes a certain distance from the circumferential side of the main body 410, so that when the support member 420 is close to the scalp, there is a certain gap between the scalp and the main body 410, ensuring the effect of heat insulation and scald protection. Of course, in addition to adopting a continuous strip structure, the support member 420 can also be configured as a multi-segment structure, with the multiple segments arranged along the axial direction and / or circumferential direction of the main body 410.

[0303] In this embodiment, a snap-in groove as a snap-in structure is provided at the position where the support member 420 is installed on the outer peripheral side of the main body 410. Correspondingly, a buckle is provided on the inner side of the support member 420. During installation, the support member 420 is placed at the installation position on the circumferential side of the main body 410, and the support member 420 is axially offset from the installation position by a distance so that the buckle and the snap-in groove are aligned. The support member 420 is then moved axially along the main body 410 so that the buckle extends into the snap-in groove and slides in the snap-in groove until the support member 420 slides into place, thereby achieving the effect of installing and fixing the support member 420 on the main body 410. Of course, a buckle can also be provided on the main body 410 and a snap-in groove can also be provided on the support member 420. The buckle and the snap-in groove can still achieve the installation and fixation of the support frame on the main body 410, or other connection methods such as bolt connection can be used between the support member 420 and the main body 410, as long as the support member 420 can be stably and reliably installed on the outer side of the main body 410.

[0304] In this embodiment, at least two raised ribs 421 are spaced apart on the outer surface of the support member 420. The raised ribs 421 extend along or perpendicular to the axis of the hair dryer attachment. The raised ribs 421 are located on the outer surface of the support member 420, that is, at the edge of the surface away from the inner cavity of the main body 410. They extend along the length of the support member 420, that is, in the axial direction of the main body 410. Since the outer surface of the support member 420 has two edge lines, two raised ribs 421 are provided, and each rib 421 is provided on opposite sides of the support member 420. The provision of the raised ribs 421 not only improves the structural strength of the support member 420, ensuring that the support member 420 can provide sufficient support, but also ensures that the support member 420 provides heat insulation and scald protection, preventing accidental scalding of the scalp due to insufficient height of the support member 420.

[0305] In addition to the raised ribs 421 provided on the outer surface of the support member 420, this embodiment also provides a depression on the outer surface. It should be noted that the outer surface referred to herein refers to the outer wall of the support member 420 away from the center of the main body 410. In addition to this outer wall, the support member 420 also has side walls adjacent to the outer wall, which are generally radially aligned with the main body 410 or form a small angle with the radial direction of the main body 410. The depression formed on the outer wall, facing inward toward the main body 410, forms the outer surface of the support member 420 in such a way that the shape of the outer surface of the support member 420 more closely conforms to the shape of the head, ensuring a tight and reliable fit between the support member 420 and the scalp.

[0306] In this embodiment, the recess is located in the middle area of ​​the outer surface of the support member 420, and the recess extends a certain length along the length of the support member 420, so that the recess can cover a larger area of ​​the outer surface of the support member 420. In this way, on the one hand, the recessed area is larger and can better fit the head shape. On the other hand, the recess in the middle does not affect the arrangement of the raised ribs 421 at the edges, so that the recess and the raised ribs 421 can each perform their respective functions without affecting each other. The specific shape of the recess can be set as needed, and can be set to a flat or curved surface. For example, the recess can be a rectangular groove or an arc-shaped groove with a certain curvature on the side.

[0307] In addition to being fixed to the main body 410 via the aforementioned buckles and slots, the support member 420 can also be installed and fixed to the first support portion 413 and the second support portion 414. In this case, a snap-fit ​​structure such as a slot can be provided at each end of the length direction of the support member 420. Accordingly, buckles, protrusions 431 and other structures can be provided on the first support portion 413 and the second support portion 414. During installation, the two ends of the support member 420 are fixed to the first support portion 413 and the second support portion 414 respectively through the engagement of the buckles and slots, thereby achieving the overall installation and fixation of the support member 420. Of course, the above-mentioned engagement with the first support portion 413 and the second support portion 414 can also be adjusted accordingly with reference to the engagement with the main body 410. At the same time, it should be noted that the components connected to the installation and fixation of the support member 420 can be selected and adjusted as needed. For example, only the support member 420 and the main body 410 are connected and fixed, or only the support member 420 and the first support part 413 and the second support part 414 are connected and fixed, or both of the above methods are used at the same time. It can actually be set according to the processing and assembly conditions.

[0308] As shown in Figures 63 and 67, the slider 430 of this embodiment is an arc-shaped plate-like member having a certain area, so that it can switch between two states: completely blocking the first air outlet channel 415 and avoiding the second air outlet channel 416, and completely blocking the second air outlet channel 416 and avoiding the second air outlet channel 416, thereby adjusting the air outlet direction. At the same time, this embodiment also provides a plurality of protrusions 431 on the outer surface of the slider 430, that is, the surface of the slider 430 away from the interior of the main body 410. The protrusions 431 can take the form of ribs, bumps, etc. In this embodiment, the protrusions 431 are striped and arranged in a sequential manner along the axis of the hair dryer accessory, so that the protrusions 431 extend along the circumference of the main body 410. In this way, the length direction of the protrusions 431, that is, the extension direction, is the same as the blowing direction. Therefore, the protrusions 431 not only provide anti-scalding and anti-slip functions, but also divert and organize the airflow, ensuring stable and reliable circumferential airflow.

[0309] In addition to the above-mentioned protrusion 431, an operating protrusion can also be set on the outer surface of the sliding member 430. The structural form of the operating protrusion can be similar to that of the protrusion 431. The difference is that the operating protrusion extends along the axial direction of the hair dryer attachment, and the operating protrusions are arranged at intervals along the circumference of the main body 410. In this way, the extension direction of the operating protrusion is perpendicular to the rotation direction of the sliding member 430, so that the operator can use the operating protrusion to move the sliding member 430, so that the sliding member 430 can be switched stably and reliably to avoid hand slippage, thereby improving the operating experience. The above-mentioned protrusion 431 and the operating protrusion can be set as needed, or both can be set at the same time. In this case, the outer surface of the sliding member 430 can be provided with a field-shaped rib, so that it has the functions of both the protrusion 431 and the operating protrusion.

[0310] In order to achieve smooth rotation of the slider 430 relative to the main frame, the slider 430 of this embodiment is provided with a rotating ring, which is sleeved on the outside of the first support portion 413. In this way, the slider 430 can be rotated relative to the main body 410 by the rotating ring, thereby switching the position of the slider 430. Of course, the rotating ring can also be provided on the outside of the second support portion 414, or rotating rings can be provided on the outside of both the first support portion 413 and the second support portion 414.

[0311] As shown in FIG63 , to facilitate operation, the first support portion 413 of this embodiment is further provided with a rotational drive portion 4131. The rotational drive portion 4131 is rotatable relative to the main body 410, and a rotating ring is fixedly mounted on the rotational drive portion 4131. Thus, a user can operate the rotational drive portion 4131 to drive the slider 430 to slide, thereby switching the position of the slider 430. The rotational drive member of this embodiment includes a knob located on the end face of the main body 410. By rotating the knob, the slider 430 can be driven to move circumferentially, thereby switching the position. The rotating drive portion 4131 or the rotating ring of this embodiment can be set to a structural form with a larger overall area, so that it can cover the end face of the main body 410. In this way, the rotating drive portion 4131 or the rotating ring can block the end face of the main body 410, so that the rotating drive portion 4131 or the rotating ring can not only drive the sliding member 430 to rotate, but also has the function of blocking the end face of the main body 410, so that the end face of the main body 410 is blocked and closed, avoiding airflow from overflowing from the end face of the main body 410, and ensuring that the airflow can only be blown out from the side air outlet channel.

[0312] Since the airflow inlet 4113 is disposed at one end of the main body 410 in this embodiment, the aforementioned rotational drive portion 4131 is disposed at the end of the main body 410 away from the airflow inlet 4113, and the first support portion 413 is also disposed at this end. A second support portion 414 is disposed at the end where the airflow inlet 4113 is located. The second support portion 414 can be configured in a ring shape, and no shielding or sealing component is required at this end, thereby allowing airflow to enter the interior of the main body 410 from this end. Of course, a rotational drive portion 4131 or a rotating ring can also be disposed at the end where the second support portion 414 is located. However, the rotational drive portion 4131 or rotating ring at this end does not need to shield or seal the end surface of the main body 410. Therefore, the rotational drive portion 4131 or rotating ring at the second support portion 414 can be configured as a hollow structure, thereby allowing airflow to pass smoothly through the airflow inlet 4113.

[0313] As shown in Figure 66, considering the sealing performance of the connection between the first support portion 413 and the second support portion 414 and the air guide bracket 417, the hair dryer accessory of this embodiment further includes a support structure 440. The support structure 440 may be a sealing ring or other structure. The support structure 440 is provided between the first support portion 413 and / or the second support portion 414 and the main body 410. Since the rotation drive portion 4131 is already provided at the location of the first support portion 413 for shielding and sealing, the support structure 440 is only provided between the second support portion 414 and the air guide bracket 417 in this embodiment. This allows the main body 410 to be sealed except for the air inlet 4113 and the air outlet channel, thereby ensuring the stability of the airflow and preventing air leakage.

[0314] Optionally, the main body 410 of this embodiment further includes a docking portion provided at the airflow inlet 4113, the docking portion and the main body 410 are connected together, and a docking structure can be provided on the docking portion as needed to achieve docking cooperation between the docking portion and components such as the hair dryer, so that the hair dryer can be stably docked on the main body 410. At the same time, in the middle area of ​​the docking portion, this embodiment also provides a baffle, which is provided in a disc shape and is located at the center of the docking portion. An airflow gap is formed between the baffle and the inner wall of the docking portion, so that on the one hand, the airflow of the hair dryer enters the main body 410 through the airflow gap, and on the other hand, the baffle can control the docking position of the hair dryer to ensure the reliability of the docking. Of course, the docking portion can also be omitted, and the hair dryer can be directly docked with the guide bracket 417.

[0315] The hair-drying device accessory of this embodiment can be used in conjunction with a hair dryer or other hair-drying device. The air outlet of the hair dryer is connected to the air flow inlet 4113 of the main body 410. Then the hair dryer blows hot air into the main body 410 and blows it out through the air outlet channel. The hot air flow transfers heat energy to the hair to stand up the hair roots, and then cold air is used to style the hair. It is convenient and quick for users to use, and there is no need to purchase traditional curling irons, egg-roll curling irons, styling products and other tools separately for tedious operations. The overall simplification of the styling process improves the user experience.

[0316] It should be noted that the multiple mentioned in this embodiment means at least two.

[0317] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

[0318] The hair dryer accessory of the present application utilizes air outlet channels to create a circular flow roughly along the circumference of the main body, effectively guiding the airflow and adhering to the circumferential surface of the main body, preventing airflow diffusion and turbulence. This ensures that the airflow is stably directed at the hair roots, ensuring a high-top styling effect. The multiple air outlet channels, combined with a sliding member, allow the airflow direction of the hair dryer accessory to be adjusted by operating the slider, allowing the airflow direction to be adjusted according to specific needs, enhancing the user experience. The support member allows the hot air to directly affect the hair roots, preventing burns from direct contact with the scalp and ensuring safety during use. The support member also helps the user identify the direction of use, preventing misuse. During use, the hair dryer accessory can be used with a hair dryer or other hair dryer, allowing users to use the hair dryer to blow hot and cold air, achieving both hot air styling and natural or cold air styling. This allows for easy creation of high-top styling with a single accessory, significantly improving the user experience.
