[0021] Referring to the FIGS. 2 and 3, the separating element 120 can be in the form of a spiral cylinder structure. The separating element 120 can be arranged in the sleeve 110, the separating element 120 can be an integrated forming member. An outlet slit 101 can be defined by portion of peripheral wall of the separating element 120 and inner wall of the sleeve 110, the outlet slit 101 can be communicated to the outlet 112. Airflow can be enters into the separating element 120 from the inlet 111 of the sleeve 110, the airflow can be diverted by the separating element 120, so that the airflow can be flowed evenly from the outlet slit 101 to the outlet 112.

[0022] Since the separating element 120 is an integrated forming member, the production process is simple, the cycle is short, and the cost is low. The hair can be followed with the flow of the airflow to automatically wrap around the device, the hair can be styled by heated and cooled airflow, the winding strength of the airflow on the hair can be natural, the hair can not be excessively pulled.

[0023] Referring to FIGS. 2 and 5, the separating element 120 can be in a shape of cylinder, the separating element 120 can include a blocking fin 1223, a plurality of connect frames 121, and a plurality of guide frames 122 in the circumferential direction of the separating element 120.

The airflow from the inlet 111 can be flowed into the separating element 120, and can be flowed into the space through the hollow 1211. Each connect frame 121 can be provided with a plurality of hollows 1211, and the plurality of hollows 1211 can be separated along the axis direction of the separating element 120. Any two adjacent hollows 1211 can be provided with a beam to separate the two adjacent hollows 1211.

[0024] Referring to FIGS. 5 and 6, the blocking fin 1223 can be provided on the guide frame 122, and arranged at one end of the separating element 120 close to the inlet 111 in the axis direction of the separating element 120. The blocking fin 1223 can be held against one end of the guide frame 122. Since the blocking fin 1223 is arranged at the inlet 111 to block the airflow from the inlet 111 into the space defined by the outer wall of the separating element 120 and the inner wall of the sleeve 110, so that the airflow can be flowed into the interior of the separating element 120, and then passed through the hollow 1211 and flowed into the space defined by the outer wall of the separating element 120 and the inner wall of the sleeve 110, and then the airflow can be flowed to the outlet 112 by the outlet slit 101. It is ensured that the airflow from the outlet 112 can be flowed in same direction to prevent appearance of disordered airflow and ensure the effect of hair styling.

[0025] In one embodiment, the blocking fin 1223 can be tightly attached to side wall of the guide frame 122, and the blocking fin 1223 can be a planar sheet structure with a length not exceeding that of a separating fin 123. When the airflow is flowed into the separating element 120 from the inlet of the sleeve 110, the airflow can be blocked by the blocking fin 1223 and cannot be flowed into the outlet slit 101 directly; the airflow can be split by the separating fin 123, one part of airflow can be flowed into the outlet slit 101, and another part of airflow can be flowed to the next separating fin 123. Since the size of the separating fin 123 is gradually increasing, the airflow passed through the next separating fin 123 will be continue to split; the airflow can be passed through the guide frame 122, the airflow can be compressed by the inner wall of the guide frame 122 and flowed to the outer wall of the adjacent guide frame 122, the outer wall of the guide frame 122 is used to direct the airflow into the outlet slit 101.

[0026] Referring to FIGS. 3 and 4, the outer wall of each guide frame 122 can include a first sidewall 1221 and a second sidewall 1222, the first sidewall 1221 and the second sidewall 1222 can be arranged in a circumferential direction of the separating element 120, the first sidewall 1221 can be held against contact the sleeve 110, the second sidewall 1222 can be provided with a plurality of separating fins 123, the plurality of separating fins 123 can be arranged at intervals in axis direction of the separating element 120. In one embodiment, each guide frame 122 can be in the shape of a sharp corner, the first sidewall 1221 can be located at one side of the guide frame 122, the second sidewall 1222 can be located at the other side of the guide frame 122.

[0027] Referring to FIGS. 2, 4 and 5, in one embodiment, the outlet slit 101 can be defined between the second sidewall 1222 and the inner wall of the sleeve 110, cross-sectional area of the outlet slit 101 can be gradually decreased in the direction of flowed airflow to squeeze the airflow, so that the flow speed of the airflow can be increased, and the airflow can be flowed more quickly to the outlet 112. The cross-sectional area of the outlet slit 101 in the direction of flowed airflow can be taken on a range of values of 3.5 mm.sup.2-5.5 mm.sup.2. In one example, the cross-sectional area of the outlet slit 101 can be 4.5 mm.sup.2, The cross-sectional area of the outlet slit 101 can be a decreasing area in the direction of the flowed airflow to allow the separated airflow to fully accelerate mixing in this area to ensure a uniform exit speed.

[0028] Referring to FIGS. 3 and 4, the sleeve 110 can include a plurality of wings 113, the plurality of wings 113 can be spaced apart in a circumferential direction of the separating element 120. The wings 113 can have a starting end 114 and a terminating end 115 in the circumferential direction of the separating element 120, in any two adjacent wings 113, the starting end 114 of one wing 113 can be separated from the terminating end 115 of another wing 113 in the radial direction of the separating element 120 to define the outlet 112, the starting end 114 of one wing 113 can be located radially inside of the terminating end 115 of another wing 113, the starting end 114 of one wing 113 can be connected with the first sidewall 1221, and the second side wall 1222 can be transitionally connected with peripheral wall of the wing 113.

[0029] In the working state, the airflow from the inlet 111 can be flowed into the interior of the separating element 120, the airflow can be passed through the spiral separating element 120 and blown out the outlet 112 at a specific angle. Since the Conda effect of the airflow, the airflow can be flowed from the starting end 114 of the wing 113 against the outer wall of the wing 113 to the terminating end 115 of the wing 113, and then the airflow can be mixed with another airflow from the starting end 114 of the next adjacent wing 113, the mixed airflow can be finally rotated on the surface of the sleeve 110. The hair near the sleeve 110 can be follow the flow of the airflow and steadily wrapped around the periphery of the sleeve 110.

[0030] It is should be noted, the Conda effect refers to the tendency of fluid to flow with the surface of a convex object instead of deviating from its original flow direction. When there is surface friction between the fluid and the surface over which it flows, the fluid will flow along the surface as long as the curvature is not large. According to Newton's third law, if a body exerts a deflecting force on a fluid, the fluid must also exert a counter deflecting force on the body. The sleeve 110 is cleverly used by the conda effect of the airflow, which can realize the automatic winding of the hair on the sleeve 110, which is convenient for the hair styling.

[0031] Referring to FIG. 4, the peripheral wall of the wing 113 can be a curved wall, the second sidewall 1222 can be a curved wall, the second sidewall 1222 can be smoothly transitioned connected with the peripheral wall of the wing 113 to guide the airflow along the peripheral wall of the wing 113.

[0032] The first sidewall 1221 of the guide frame 122 can be arranged adjacent to the starting end 114 of the wing 113. In the circumferential direction of the separating element 120, there are provided six guide frames 122 and six wings 113, that is, there are six groups of structures with the first sidewall 1221 adjacent to the starting end 114 of wing 113, these structure can not only make the separating element 120 and the sleeve 110 stably close together, but also make the airflow rotated in the separating element 120 and the sleeve 110, and flowed out from the outlet 112 at a predetermined angle, and the airflow can be moved along the peripheral wall of the wing 113. It is should be noted that the number of wings 113 is not limited, the number of wings 113 can be increased or decreased based on experiments. It should be emphasized that when processing the sleeve 110, an integrated tubular structure can be used to process a fluid outlet in the tubular structure, and a wing 113 can be formed between any two adjacent fluid outlets, and then formed a complete sleeve 110.

[0033] Since the smooth transition between the second sidewall 1222 and the peripheral wall of the wing 113, the curvature of the second sidewall 1222 of the separating element 120 and the peripheral surface of the wing 113 can be continuous, which can reduce the interference to the airflow at the connection position, so that the airflow passed through these positions will not turbulent, the airflow can be flowed against the peripheral wall of wing 113. The curvature continuity means that the surface or curve point is continuous, and the curvature analysis results are continuous changes.

[0034] Referring to FIGS. 3 and 4, the outer profile radius R of the cross section of the sleeve 110 can be 30 mm or 40 mm. It should be noted that the size of the outer profile radius can not be limited, and it can be adjusted by user's requirement. In some embodiments, the width w of the outlet 112 can be 0.4 mm, the length can be 140 mm, and the number of the outlet 112 can be six, the cross-sectional area of the outlet 112 can be 300-350 mm.sup.2, preferably 336 mm.sup.2.

[0035] Referring to FIGS. 4 and 7, the distance between any two adjacent separating fins 123 can be ranged from 5 mm to 12 mm. For example, the distance between any two adjacent separating fins 123 can be 5 mm, 8.5 mm, or 12 mm.

[0036] The number of separating fins 123 on each second sidewall 1222 can be 10 to 30, In one embodiment, the number of separating fins 123 on each second sidewall 1222 is 16.

[0037] The separating fin 123 can have a first end 1231 and a second end 1232 opposite the first end 1231 in the circumferential direction of the separating element 120, the second end 1232 can be offset relative to the first end 1231 towards the axis direction of the separating element 120, and offset angle can be less than or equal to 30 degree. In one embodiment, the offset angle can be 16.5 degree. It should be noted that in the actual test process, if the offset angle is less than 0 degree, the hair cannot be evenly wound around the sleeve 110 when the hair is concentrated on the sleeve 110; if the offset angle is greater than 30 degree, the hair cannot be effectively wound around the peripheral of the sleeve 110.

[0038] The sides of the separating fin 123 in the direction of the separating element 120 are a first side 1233 and a second side 1234, both the first side 1233 and the second side 1234 can be extended roughly along the radial direction of the sleeve 110. The length of the first side 1233 can be greater than the length of the second side 1234, that is, the first side 1233 is the long side, the second side 1234 is the short side. The length of the second side 1234 can be ranged from 0.5 mm to 1.2 mm, the length of the first side 1233 can be ranged from 2.20 mm to 5.60 mm.

[0039] In some embodiments, the length of the second side 1234 can be 0.5 mm, 0.9 mm or 1.2 mm, the length of the first side 1233 can be 2.20 mm, 2.26 mm, 2.38 mm, 2.54 mm, 2.72 mm, 2.92 mm, 3.13 mm, 3.35 mm, 3.57 mm, 3.81 mm, 4.04 mm, 4.29 mm, 4.55 mm, 4.84 mm, 5.17 mm or 5.60 mm. It is ensured that the uniformity of the separation of the separating fin 123, which is the optimum value for the simulation calculations.

[0040] In some embodiments, the area of the separating fin 123 can be gradually increased from the inlet 111, the size of the second side 1234 (i.e. short side) of the separating fin 123 can be unchanged, and the size of the first side 1233 (i.e. long side) can be gradually increased, the offset angle of the separating fin 123 can be fixed.

[0041] Referring to FIGS. 4 and 6, a plurality of separating fins 123 disposed on one second sidewall 1222 can be gradually increased in the axis direction of the separating element 120, that is, the length of the separating fin 123 can be gradually increased in the circumferential direction of the separating element 120, the surface area of the separating fin 123 can be gradually increased, the area of the sidewall on the separating fin 123 perpendicular to the axis of the separating fin 120 can be gradually increased.
