[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] See Figure 1-7 As shown, a comb cover with retractable comb teeth comprises: a cylindrical shell 1 and a plurality of comb teeth 2 mounted on the cylindrical shell 1 and an end cover 3 arranged at the end of the cylindrical shell 1. The cylindrical shell 1 has a through hole 11 for the convex tooth portion 21 of the comb teeth 2 to pass through.

[0027] The cylindrical shell 1 is provided with a rotating shaft 4, and the rotating shaft 4 is provided with a connecting portion 41 on the outside, and the connecting portion 41 is rotatably connected with the comb teeth 2; the end cover 3 is provided with a knob 5 for driving the rotating shaft 4 to rotate, and the knob 5 is fixedly assembled with the end of the rotating shaft 4; when the knob 5 is turned to drive the rotating shaft 4 to rotate, the rotating shaft 4 pulls the comb teeth 2 to retract and store inside the cylindrical shell 1, or the rotating shaft 4 pushes the comb teeth 2 to extend outward to be exposed outside the cylindrical shell 1, so that the comb teeth 2 can realize the telescopic function. When the utility model is in use, it can be used in conjunction with a hot air comb or a hair dryer 6, that is, the other end of the cylindrical shell 1 provided with the end cover 3 is set on the hot air comb or the hair dryer 6, and the hot air generated when the hot air comb or the hair dryer 6 is working is directly blown to the periphery of the cylindrical shell 1. When the hair is curled and styled, after the knob 5 is turned to drive the rotating shaft 4 to rotate, the rotating shaft 4 pushes the comb teeth 2 to extend outward to be exposed outside the barrel shell 1, so that the comb set can comb and curl the hair, and the hot air is blown out by the hot air comb or the hair dryer 6 to style the curly hair. After completion and when the comb set needs to be taken off, the knob 5 is first turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract and store them inside the barrel shell 1. At this time, the comb teeth 2 no longer touch the hair, so that the comb set can be smoothly taken out of the relatively styled hair, and the comb teeth will not touch the hair to affect the hair styling effect, thereby ensuring that the style of the hair after styling is more beautiful and the quality is better. Moreover, when the comb set is not needed, the knob 5 can be turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract and store them inside the barrel shell 1, thereby protecting the comb teeth 2, and at the same time, the volume of the entire comb set can be reduced, which is convenient for carrying and storage, and more convenient to use.

[0028] The specific structure of the comb teeth 2 is as follows:

[0029] The comb teeth 2 include a rod body 22 and a plurality of convex teeth 21 arranged at intervals on the rod body 22 and in the shape of vertical strips. The convex teeth 21 are arranged in a row and are integrally connected to the rod body 22. The connecting portion 41 is C-shaped and has a movable connecting groove 411. Since the connecting portion 41 is C-shaped, the notch size of the movable connecting groove 411 is smaller than the inner cavity size of the movable connecting groove 411, so that it can be well engaged with the rod body 22, thereby forming a stable rotatable connection, that is, when the rod body 22 is nested in the movable connecting groove 411 and can move in the movable connecting groove 411, it can prevent the rod body 22 from accidentally detaching from the movable connecting groove 411, thereby ensuring the stability of the assembly structure. When the knob 5 is turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract, the rod body 22 will rotate in the movable connection groove 411, and at the same time, affected by the rotation of the rotating shaft 4, the rod body 22 rotates with the rotating shaft 4, and then retracts and is stored in the cylinder shell 1. The longitudinal section of the rod body 22 is circular, so that it can be connected with the movable connection groove 411 more stably and the relative rotation is smoother. And the longitudinal section size of the rod body 22 is larger than the size of the root of the convex tooth part 21, so that the structure of the comb teeth is more stable.

[0030] The inner opening of the through hole 11 is provided with a first vertical curved surface 111 and a first inclined curved surface 112 opposite to the first vertical curved surface 111; the outer opening of the through hole 11 is provided with a second vertical curved surface 113 and a second inclined curved surface 114 opposite to the second vertical curved surface 113, and the second vertical curved surface 113 and the first inclined curved surface 112 are located on the same side, and the lower edge of the second vertical curved surface 113 is connected to the upper edge of the first inclined curved surface 112; the first vertical curved surface 111 and the second inclined curved surface 114 are located on the same side, and the lower edge of the second inclined curved surface 114 is connected to the upper edge of the first vertical curved surface 111, and the first inclined curved surface 112 and the second inclined curved surface 114 are parallel to each other. When the knob 5 is turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract, the rod body 22 will rotate in the movable connection groove 411, and at the same time, affected by the rotation of the rotating shaft 4, the rod body 22 rotates with the rotating shaft 4. At this time, the two sides of the convex tooth portion 21 of the comb tooth 2 are respectively in contact with the first inclined arc surface 112 and the second inclined arc surface 114, and then retract along the first inclined arc surface 112 and the second inclined arc surface 114, and its operation is smoother.

[0031] The number of the connecting parts 41 is multiple, and each group of connecting parts 41 is distributed in a straight line and connected to the same rod 22, so as to ensure that each comb tooth is stably installed with the connecting part 41. In this embodiment, the number of the connecting parts 41 is six, and the number of comb teeth is also six, and one comb tooth is installed in cooperation with one group of connecting parts 41.

[0032] The end surface of the connecting portion 41 is configured to be arc-shaped, so that when the rotating shaft 4 rotates, the connecting portion 41 will not contact the inner wall of the cylindrical shell 1, and its operation is smoother.

[0033] The end of the rotating shaft 4 is provided with an elastic buckle 42 protruding outward, and the knob 5 is provided with a clamping hole 51 adapted to the elastic buckle 42. The knob 5 is inserted into the end of the rotating shaft 4, and the clamping hole 51 is clamped and fixed with the elastic buckle 42, so that the knob is fixed to the end of the rotating shaft 4.

[0034] A stroke limiting protrusion 43 is also provided at the end of the rotating shaft 4; a stroke limiting groove for limiting the rotation angle range of the rotating shaft 4 is also provided on the inner wall of the cylinder shell 1. The stroke limiting protrusion 43 is placed in the stroke limiting groove, so as to limit the rotation angle of the rotating shaft 4, thereby preventing the rotating shaft 4 from excessively rotating and excessively pulling back the comb teeth, so that the convex tooth portion 21 of the comb teeth can no longer be extended from the through hole 11. That is to say, through the cooperation of the stroke limiting protrusion 43 and the stroke limiting groove, it can be ensured that after the convex tooth portion 21 of the comb teeth is retracted into the cylinder shell 1, the convex tooth portion 21 can later extend from the through hole 11 to protrude outside the cylinder shell 1, thereby realizing the function of combing hair.

[0035] The end of the cylinder shell 1 opposite to the end cover 3 is fixed with a connection cover 13 for connecting with the air outlet 61 of the hot air comb or hair dryer 6, and the connection cover 13 is provided with a plurality of air holes 131 facing the outer surface of the cylinder shell 1. When working, the hot air generated by the hot air comb or hair dryer 6 will be blown out from the air outlet 61, and will pass through the air holes 131 and blow to the outer surface of the cylinder shell 1, and then the hair combed and curled by the comb teeth on the outside of the cylinder shell 1 will be fixed. Among them, the end of the cylinder shell 1 opposite to the end cover 3 is also provided with an elliptical air guide surface 14, and the air guide surface 14 is connected with the air holes 131, and the hot air can be better guided to the outer surface of the cylinder shell 1 through the air guide surface 14. Among them, the connection cover 13 is integrally connected with the air outlet 61 of the hot air comb or hair dryer 6, or the connection cover 13 and the air outlet 61 of the hot air comb or hair dryer 6 are detachably installed, that is, the comb cover of the retractable comb teeth of the utility model is used as an accessory of the hot air comb or hair dryer.

[0036] The end cover 3 has a window 31 for the knob 5 to pass through, and the end cover 3 is provided with a plurality of spring pieces 32, each of which is provided with a buckle hole 321. The inner wall of the cylinder shell 1 is provided with an undercut 15. After the end cover 3 and the cylinder shell 1 are sleeved, the spring pieces 32 of the end cover 3 are embedded in the inner wall of the cylinder shell 1 and are fixed with the undercut 15.

[0037] In summary, the utility model can be used in conjunction with a hot air comb or a hair dryer 6 when in use, that is, the other end of the barrel shell 1 provided with the end cover 3 is provided on the hot air comb or the hair dryer 6, and the hot air generated when the hot air comb or the hair dryer 6 is in operation is directly blown to the outer periphery of the barrel shell 1. When the hair is curled and styled, after the knob 5 is turned to drive the rotating shaft 4 to rotate, the rotating shaft 4 pushes the comb teeth 2 to extend outward to be exposed outside the barrel shell 1, so that the comb set can comb and curl the hair, and the hot air is blown out by the hot air comb or the hair dryer 6 to style the curly hair. After completion and when the comb set needs to be removed, the knob 5 is first turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract and store them inside the barrel shell 1. At this time, the comb teeth 2 no longer touch the hair, so that the comb set can be smoothly taken out of the relatively styled hair, and at the same time, the comb teeth will not touch the hair to affect the hair styling effect, thereby ensuring that the style of the hair after styling is more beautiful and of better quality. Furthermore, when the comb cover is not in use, the knob 5 can be turned to drive the rotating shaft 4 to rotate, and the rotating shaft 4 pulls the comb teeth 2 to retract and store them inside the cylinder shell 1, thereby protecting the comb teeth 2. At the same time, the volume of the entire comb cover can be reduced, which is convenient for carrying and storage and more convenient to use.
