[0035] It should be noted that in combination with the Coanda effect, the Coanda effect (Coanda Effect) is also called wall attachment effect or Coanda effect. Fluid (water flow or air flow) deviates from the original flow direction and tends to flow along the surface of the protruding object. When there is surface friction between the fluid and the surface of the object through which the fluid flows (or the fluid viscosity), as long as the curvature is not large, the fluid will flow along the surface of the object (i.e. the outer wall of the sleeve 100), and the user's hair can be wound on the sleeve 100 to achieve curling in the first direction in the first state or in the second direction in the second state.

[0036] The sleeve 100 is provided with an air passage, one end of the air passage is provided with an opening for receiving airflow, and the outer surface is circumferentially spaced apart to provide a plurality of groups of air outlets. Each group of air outlets includes left and right air outlets 110 and 120 arranged in opposite directions. The left and right air outlets in the present application only represent the left and right sides, and do not limit the direction of the air outlets, i.e. the left air outlet can be left or right, and the right air outlet can be right or left, but the directions of the left and right air outlets need to be opposite.

[0037] As shown in the drawings, Figure 6As shown, in the embodiment, six groups of air outlets are adopted, each group of air outlets is provided with a left air outlet and a right air outlet, and the outer sleeve is in a columnar structure, each group of air outlets is arranged along the outer wall of the outer sleeve in a circumferential direction, and each group of air outlets extends along the axis of the outer sleeve, and preferably each air outlet can be divided into a plurality of small air outlets, so as to ensure that the air volume of each air outlet is consistent.

[0038] As shown in the drawings, Figure 5 As shown, the air guide sleeve 500 is inserted into the outer sleeve 100 and uniformly divides the air passage into a plurality of independent sub-air passages, the air guide sleeve 500 includes a center column 530 and a plurality of partitions 510 which are arranged equidistantly in a circumferential direction with the center column 530 as the center, each partition 510 forms an independent sub-air passage, that is, the air guide sleeve uniformly divides the cylindrical space into a plurality of sub-air passages, and the size of each sub-air passage is consistent, so as to ensure that the air volume is uniform, and the sub-air passage is divided into a first air passage 10 which is in communication with the left air outlet 110 and a second air passage 20 which is in communication with the right air outlet 120, and each sub-air passage is in communication with the opening, that is, each sub-air passage is independently in communication with the air outlet of the hair dryer main body.

[0039] In order to make the air guide sleeve cooperate with the outer sleeve more accurately, a plurality of insertion grooves are arranged on the inner wall of the outer sleeve in the axial direction, the insertion grooves are located between adjacent two groups of air outlets, after the air guide sleeve is inserted into the outer sleeve, part of the partitions are inserted into the insertion grooves, and the partitions between the partitions located in adjacent insertion grooves are in close contact with the inner wall of the outer sleeve, so as to divide the air passage corresponding to each group of air outlets to form the first air passage and the second air passage.

[0040] As shown in the drawings, Figure 4 As shown, the rotating sealing member 200 is arranged at the opening, and the rotating sealing member 200 is rotatably arranged relative to the outer sleeve 100, and the rotating sealing member 200 is provided with an air inlet face 230 and a sealing face 220 which are alternately arranged, the sealing face and the air inlet face are alternately distributed in a circumferential direction, and the area of the air inlet face is equal to the cross-sectional area of the sub-air passage, that is, the sealing face can completely close the air inlet of a sub-air passage, and the air inlet face is a through face, by rotating the rotating sealing member 200, the position of the sealing face between the first air passage and the second air passage can be switched, and in order to better realize the sealing effect, the sealing face is in a triangular shape, the lower edge of the sealing face is in contact with the partition of the air guide sleeve, that is, when the rotating sealing member 200 is rotated to a position, two edges of the sealing face are in contact with the edges of the partitions on both sides of the corresponding sub-air passage.

[0041] In the first state, the sealing face 220 closes the air inlet of the first air passage 10, the air inlet face 230 is in communication with the second air passage 20, and the flow direction of the air outlet of the right air outlet 120 is the first rotation direction.

[0042] As shown in the drawings, Figure 9As shown in Figure I, the sealing surface blocks the air inlet of the first air duct 10, while the second air duct 20 is connected to the air inlet surface. At this time, the air delivered by the blower body enters each of the second air ducts through the air inlet surface, and the second air ducts are connected to each of the right air outlets 120, as shown in Figure I. Figure 9 As shown in Figure II, the airflow is ejected in the same direction.

[0043] In the second state, the sealing surface 220 closes the air inlet of the second air passage 20, the air inlet surface 230 is connected to the first air passage 10, and the airflow direction of the left air outlet 110 is the second vortex direction, and the first vortex direction is opposite to the second vortex direction.

[0044] like Figure 8 As shown, the sealing surface blocks the air inlet of the second air duct 20, while the first air duct 10 is connected to the air inlet surface. At this time, the air delivered by the blower body enters each of the first air ducts through the air inlet surface, and the first air ducts are connected to each of the left air outlets 110, as shown. Figure 8 As shown in Figure II, the airflow is ejected in the same direction.

[0045] refer to Figure 8 and Figure 9 In section II, the airflow directions of the two components are set in opposite directions, thereby enabling the switching of airflow direction.

[0046] The first direction of rotation is defined as the airflow flowing counterclockwise or approximately counterclockwise along the outer wall of the curling iron, and the second direction of rotation is defined as the airflow flowing clockwise or approximately clockwise along the outer wall of the curling iron. Of course, the definitions of the first and second directions of rotation cannot be used as limiting conditions; as long as the first and second directions of rotation are opposite, different curling directions can be achieved.

[0047] The outer casing 100 is provided with several arc-shaped plates 300 spaced circumferentially, and each arc-shaped plate 300 covers a portion of the air outlet on both sides, forming gaps with the outer casing that communicate with the left air outlet 110 and the right air outlet 120 respectively. The air outlet is set along the surface of the outer casing, with its end slightly protruding above the outer surface of the outer casing. Therefore, when the arc-shaped plates are placed on top of it, the surface of the air outlet is completely sealed by the arc-shaped plates, with only a gap exposed on the side, allowing airflow to be discharged from the gap, thus achieving a counterclockwise or clockwise airflow direction.

[0048] The inner two ends of the arc-shaped plate 300 form a first flow guide surface 320 and a second flow guide surface 310, the first flow guide surface 320 extends along a first rotation direction, the second flow guide surface 310 extends along a second rotation direction, the first flow guide surface 320 covers the right air outlet 120, and the second flow guide surface 310 covers the left air outlet 110. The design of the first flow guide surface and the second flow guide surface is that the distance between the flow guide surface and the outer sleeve gradually decreases from the air inlet end to the air outlet end. According to the design, the fluid gradually compresses the movement space when flowing, thereby increasing the fluid flow rate in the curling iron, increasing the air outlet speed, improving the curling effect, and on the other hand, extruding the fluid to flow in the air outlet direction, thereby improving the air outlet efficiency.

[0049] The arc-shaped plate 300 is connected with the outer sleeve 100 through buckling, as shown in the drawings, Figure 7 In this embodiment, the buckling connection is achieved in a sliding fit manner, that is, one end of the outer sleeve is provided with a guide groove, the arc-shaped plate is inserted into the guide groove in the opening direction, and after being in place, the buckling of the arc-shaped plate is matched with the buckling position on the outer sleeve to achieve buckling connection, and the insertion end is locked by the head cover 400, thereby preventing the arc-shaped plate from falling. In other embodiments, the buckling connection can also be directly achieved.

[0050] As shown in the drawings, Figure 2 And Figure 3 As shown in the drawings, the air guide sleeve 500 is provided with a gear slot 520 on the side matched with the rotating blocking piece 200, the rotating blocking piece 200 is provided with a gear indicating piece arranged in the gear slot 520, and the gear slot 530 is used to avoid the gear indicating piece on the rotating blocking piece 200, so that when the outer sleeve and the rotating blocking piece relatively rotate, the gear indicating piece moves in the gear slot, thereby limiting the maximum moving distance and avoiding excessive rotation.

[0051] The gear indicating piece includes a ball seat 210, a ball 700 arranged in the ball seat 210, and an elastic piece arranged between the ball 700 and the ball seat 210. The elastic piece is a spring, so that the ball can always be in close contact with the inner wall of the outer sleeve. Two grooves 130 are arranged at the corresponding positions of the inner wall of the outer sleeve, which represent the clockwise and counterclockwise gears respectively. The gear indicating is achieved by using the jerk feeling of the ball moving from one groove to another groove.

[0052] The O-shaped ring 600 is arranged between the rotating blocking piece 200 and the outer sleeve 100. The design of the O-shaped ring 600 is mainly to provide damping feeling during rotation, so that the rotating feeling is better.

[0053] The outer cover 100 is provided with an openable head cover 400 at the upper end, which is mainly designed for installation of the arc-shaped plate and is detachably connected with the outer cover through thread or 7-shaped buckle position cooperation, and after being fixed with the outer cover, the arc-shaped plate can be limited and fixed.

[0054] The embodiments should not be regarded as limiting the utility model, but any improvement based on the spirit of the utility model should be within the protection scope of the utility model.
