The lower cover 102 of the air duct is smoothly connected, part of the circumference of the guide tube 13 is covered by the upper cover 101 of the air duct and the two are arranged at an interval, the outer wall surface of the guide tube 13 and the end of the upper cover 101 of the air duct define the air outlet 12, and the end of the assembly part 15 defines an air inlet 11 for receiving the airflow from the hair dryer. The airflow flows from the outlet of the air outlet 12 along the outer wall of the guide tube 13 to form a negative pressure, thereby achieving the adsorption of hair and preventing the hair ends from flying according to the Coanda effect. The assembly part 15 is used to be detachably connected to the hair dryer, and the detachable connection method includes snap connection, magnetic attraction or threaded connection, etc.

[0042] like Figure 8-11As shown, the comb tooth part 2 includes a heating component 21 and a comb tooth component 22, and the heating component 21 is used to heat the comb tooth component 22. The heating component 21 can be directly connected to the comb tooth component 22, or can be connected to the comb tooth component 22 through a heat conductor, in order to provide heat to the comb tooth component 22, so that the hair can be thermoformed and shaped through the comb tooth component 22 while blowing the hair. The attachment is also provided with a first conductive member 213, and the hair dryer 5 is provided with a second conductive member 51 that cooperates with the first conductive member 213. The first conductive member 213 is electrically connected to the heating component 21, and the second conductive member 51 is electrically connected to a power source. After the attachment and the hair dryer 5 are assembled in place, the first conductive member 213 and the second conductive member 51 are electrically coupled. The hair dryer 5 has a control switch and a circuit board, the control switch is used to control electrical conduction, and the circuit board is used to control whether the heating component works or the power when working.

[0043] Furthermore, the comb-tooth portion 2 is located above the air duct upper cover 101, and the comb-tooth portion 2 and the air duct upper cover 102 are arranged with a gap, or can be arranged in contact with each other. A gap arrangement is preferred, which can reduce the friction force that the comb-tooth portion 2 needs to overcome when rotating.

[0044] The comb tooth assembly 22 includes comb teeth 222, and the comb teeth 222 include a connecting portion 2221 and a combing portion 222 connected thereto. The connecting portion 2221 is provided with a receiving cavity 224 for accommodating a heating component, which facilitates the rapid conduction of heat, improves the heat conduction efficiency, and reduces the volume of the product. Furthermore, the comb tooth assembly 22 also includes a sheath tooth 223, and the sheath tooth 223 is sleeved on the outside of the comb tooth 222. One end of the sheath tooth 223 is connected to the connecting portion 2221 and is in the first position, and the other end is in a gap fit with the combing portion 2222, so as to form air insulation. This design can ensure that the surface temperature of the anti-flying aluminum tooth sheath will not be too high, thereby avoiding burns. The comb teeth 222 are made of aluminum, and the sheath teeth 223 are made of rubber; in this way, the comb teeth 222 can conduct heat better, and with the protection of the sheath teeth 223, the skin will not be burned.

[0045] The comb tooth assembly 22 also includes a support 221 and a pressure cover 225. The support 221 is connected to the connecting portion 2221 and is in the second position. The second position is located on one side of the first position. Compared with the first position, the second position is closer to the air inlet 11. The pressure cover 225 is located above the connecting portion 2221 and covers the first position and the second position. The pressure cover 225 is fixedly connected to the sheath teeth 223. It can be understood that the pressure cover 225 is fixedly connected to the support 221; or the pressure cover 225 is fixedly connected to the support 221 and the sheath teeth 223 at the same time. In this example, a positioning column 2251 is provided on the pressure cover 225, and a positioning hole 2231 that cooperates with the positioning column 2251 is provided on the tooth guard 223, and the positioning column 2251 is inserted into the positioning hole 2231.

[0046] In this example, the heating component 21 includes a heating unit 211 and a temperature detection unit 212, both of which are arranged in the accommodating cavity 224, and the temperature of the heating unit is detected in real time to reduce the detection error of the temperature of the heating unit 211. It can be understood that only the heating unit 211 is arranged in the accommodating cavity 224, and the temperature detection unit 212 is preferably NTC.

[0047] The accessory further includes a rotating mechanism 3 , which drives the comb-tooth portion 2 to rotate relative to the air flow portion 1 .

[0048] More specifically, the rotating mechanism 3 includes a bracket 31 and an axis core 32, wherein the lower part of the bracket 31 is fixedly connected to the axis core 32, the upper part of the bracket 31 is fixedly connected to the comb-tooth portion 2, and the axis core 32 is coaxially installed in the guide tube 13 and is rotatably connected to the guide tube 13. The bracket 31 has two ends respectively located at the axis core 32 and the guide tube 13, and the comb-tooth portion 2 is located above the guide tube 13 and between the two brackets 31. The axis core 32 includes a first cylinder 321 and a second cylinder 322, the first cylinder 321 passes through the guide tube 13, the second cylinder 322 is sleeved on the outside of the first cylinder 321, and the second cylinder 322 is connected to one of the brackets 31, the second cylinder 322 and the bracket 31 can be split parts and fixedly connected, or can be integrally formed, preferably in an integrally formed manner. The second cylinder 322 is fixedly connected to the first cylinder 321, and the connection method is preferably screw connection. The inner wall of the air guide tube 14 is circumferentially provided with a plurality of slots 42 , and the outer wall of the second cylinder 322 is provided with a snap-fitting protrusion 41 that cooperates with the slots. When an external force acts on the shaft core 32 , the shaft core 32 rotates, thereby driving the comb tooth portion 2 to rotate relative to the air flow portion 1 .

[0049] It can be understood that the shaft core 32 only includes the first cylinder 321, the first cylinder 321 is set through the guide cylinder 13, the bracket 31 includes two and respectively connected to the two ends of the first cylinder 321, the lower part of the bracket 31 is fixedly connected to the first cylinder 321, and the upper part of the bracket 31 is fixedly connected to the comb tooth part 2. The inner wall of the air guide cylinder 14 is provided with a plurality of slots 42 in the circumferential direction, and the outer wall of the first cylinder 321 is provided with a snap-fitting protrusion 41 that cooperates with the slots. When an external force acts on the shaft core 32, the shaft core 32 rotates, thereby driving the comb tooth part 2 to rotate relative to the air flow part 1.

[0050] The fixing method of the bracket 31 and the comb tooth part 2 can be fixed by screws or by buckles. In this example, the buckle fixing connection method is preferred to reduce costs and improve assembly efficiency. Further, in order to improve assembly efficiency, a positioning structure, such as a positioning column, a positioning hole, etc., can also be provided to achieve rapid assembly of the bracket 31 and the comb tooth part 2.

[0051] Furthermore, in order to facilitate user operation, the rotating mechanism 3 further includes a driving handle 36, which is disposed in the shaft core 32, making full use of space and reducing the volume of the accessory. In this example, the driving handle 36 passes through the first cylinder 321, which is conducive to improving structural stability and operational convenience, so that the user can operate from both ends of the first cylinder 321.

[0052] The above-mentioned method of realizing the rotation of the comb teeth 2 can realize the wall flow of the outlet airflow along the curved surface of the guide tube 13 to prevent the hair ends from flying. At the same time, the internal cavity of the guide tube 13 is directly used to form a rotating mechanism 3, thereby improving the overall space utilization of the accessory, making the structure more compact, and reducing the volume of the accessory.

[0053] Furthermore, the accessory also includes two end covers 4, which are respectively arranged on both sides of the air guide tube 14. The two end covers 4 are respectively fastened to the two brackets 31 by snapping. The shape of the two end covers 4 is the same as that of the brackets 31, which can realize a hidden assembly structure with better structural integrity.

[0054] The multiple arc-shaped slots 34 are arranged on the circumferential direction of the inner wall of the guide tube 13, and the engaging protrusions 33 are arranged on the outer wall of the shaft core 32. The engaging protrusions 33 cooperate with the arc-shaped slots 34 to realize the position rotation and position locking of the comb tooth part 2. The multiple arc-shaped slots 34 are divided into at least two groups, each group has multiple arc-shaped slots 34, and the inner wall of the guide tube 13 is provided with a limit plate 35 separating each group of arc-shaped slots. The shaft core 32 is provided with a limit part 323 cooperating with the limit plate 43. Specifically, the multiple arc-shaped slots 34 arranged on the inner wall of the guide tube 13 are divided into three groups, and each group of arc-shaped slots 34 is separated by three limit plates 35 distributed 120° circumferentially, and the limit plates 35 are used to limit the rotation angle of the comb tooth part 2. Each group is composed of four arc-shaped slots 34, and each group of arc-shaped slots corresponds to a clamping protrusion 33, which is fixed on the outer wall of the shaft core 32. When the torque of the shaft core 32 reaches a certain value, the clamping protrusion 33 can slide between the multiple arc-shaped slots 34, thereby realizing a specific angle rotation of the comb tooth assembly 22. The limiting portion 323 can be a protrusion extending on the outer wall of the second cylinder 322, or a corresponding avoidance groove is provided on the second cylinder 322, and the limiting portion 323 extends into the avoidance groove, and the wall surface of the second cylinder 322 that defines the avoidance groove forms the limiting portion 323, or it can be a mixture of the two. The limiting portion in this example is the latter.

[0055] See also Figures 8 to 11 , which respectively illustrate the comb tooth portion 2 under the action of the rotating mechanism 3 to make 0°, 15°, 30° and 45° rotation angle states. Within this rotation angle range, it is convenient for the operator to use and can meet different daily styling needs. The rotation angle is the angle α between the central axis of the comb tooth 222 and the horizontal line (such as Fig. 9 as shown).
