Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular to a cold air curling iron. Background Technology

[0002] In existing technology, curling irons include a handle, a heating rod mounted on the handle, comb teeth that rotate on the handle, and a drive motor that drives the comb teeth to rotate. During operation, the hair is wrapped around the heating rod by the rotation of the comb teeth, and the hair is curled by the operation of the heating rod. Some products on the market have air vents on the heating rod and blow air through them to achieve rapid cooling, styling, and anti-frizz effects. However, placing the air vents on the heating rod affects the layout of the internal heating elements, and the cold air blowing directly out of the heating rod can also affect its operation. Its structural layout is relatively unreasonable. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a cold air curling iron with the cold air outlet set on the handle and located on both sides opposite the heating rod. Without affecting the layout of the heating rod, it also increases the effect of cold air styling. Its structure is relatively simple and easy to process.

[0004] This utility model discloses a cool-air curling iron, including a handle, a heating rod disposed on the handle, comb teeth rotatably disposed on the handle, and a drive motor for driving the comb teeth to rotate. The handle is also provided with a fan and an air outlet. The fan is disposed inside the handle and faces the air outlet, and an air inlet is provided on the handle corresponding to the air inlet end of the fan. The handle is also provided with a circuit board for controlling the operation of the heating rod, the drive motor, and the fan. The feature is that the handle is provided with an arc-shaped outwardly extending air outlet ear, which is located on both sides opposite to the heating rod, and the air outlet is disposed on the air outlet ear. When the fan is working, the airflow forms an inverted V-shaped airflow through the air outlet ear and the air outlet.

[0005] Using the above technical solution, when in use, the comb teeth are rotated by the drive motor, and the hair can be wrapped around the heating rod. The hair can be permed by the preheated heating rod. The fan blows air into the air outlet. The air outlet is extended in an arc shape, which can provide a set space for the air outlet, thereby guiding the airflow towards the opposite sides of the heating rod. There is no need to widen the head of the handle as a whole, and an inverted V-shaped airflow is formed, which can accelerate the cooling and styling of the hair and prevent frizz.

[0006] A further feature of this invention is that the fan is located at the tail of the handle, and the drive motor and circuit board are located at the front of the fan, so that the air outlet of the fan faces the drive motor and circuit board.

[0007] The above technical solution not only accelerates the cooling of the hair during operation, but also cools the circuit board and drive motor, achieving multiple benefits in one go, and the layout is quite reasonable.

[0008] A further feature of this invention is as follows: the handle is provided with a middle frame for assembling a drive motor, and the comb teeth are provided with a base. The base is hollow and forms an assembly hole, and an annular boss is provided on the assembly hole. The middle frame is inserted into the handle through the assembly hole and is fixedly connected to the handle. A first limiting boss is provided on the handle below the annular boss, and a second limiting boss is provided on the middle frame above the annular boss. The first limiting boss and the second limiting boss cooperate to form a rotating cavity, and the annular boss is rotatably disposed in the rotating cavity.

[0009] By adopting the above technical solution, the first limiting boss and the second limiting boss can provide installation space for the annular boss without affecting its normal rotation, and can also prevent it from falling out, making it more stable during use.

[0010] A further feature of this invention is that the top of the annular boss is provided with a first arc-shaped protrusion that abuts against the bottom of the second limiting boss, and the bottom of the annular boss is provided with a second arc-shaped protrusion that abuts against the top of the first limiting boss.

[0011] Using the above technical solution, if the annular bosses are in direct contact, their contact area is relatively large, thus overcoming a large amount of friction. Using arc-shaped protrusions for contact can prevent relative wobbling and reduce the contact area, thereby reducing the energy consumption when overcoming friction. Attached Figure Description

The handle 1 is also provided with a circuit board 9 for controlling the operation of the heating rod 2, the drive motor 4, and the fan 5. In an embodiment of this utility model, the handle 1 is provided with an arc-shaped outwardly extending air outlet ear 8. The air outlet ear 8 is located on both sides opposite to the heating rod 2, and the air outlet 6 is disposed on the air outlet ear 8. When the fan 5 is working, the airflow forms an inverted V-shaped airflow through the air outlet ear 8 and the air outlet 6.

[0015] Using the above technical solution, when in use, the comb teeth 3 are rotated by the drive motor 4, and the hair can be wrapped around the heating rod 2. The hair can be permed by the preheated heating rod 2. The fan 5 blows air into the air outlet 6. The air outlet ear 8 is extended in an arc shape, which can provide a set space for the air outlet 6, thereby guiding the airflow towards the opposite sides of the heating rod 2 without widening the head of the handle 1.

[0016] The fan 5 is located at the tail of the handle 1, and the drive motor 4 and circuit board 9 are located in front of the fan 5 so that the air outlet of the fan 5 faces the drive motor 4 and circuit board 9. When working, it can not only accelerate the cooling of the hair, but also cool the circuit board 9 and drive motor 4. It has multiple benefits and the layout is relatively reasonable.

[0017] The handle 1 is provided with a middle frame 11 for assembling the drive motor 4, and the comb teeth 3 are provided with a base 10. The base 10 is hollow and forms an assembly hole 12, and an annular boss 13 is provided on the assembly hole 12. The middle frame 11 is inserted into the handle 1 through the assembly hole 12 and is fixedly connected to the handle 1. A first limiting boss 14 is provided on the handle 1 below the annular boss 13, and a second limiting boss 15 is provided on the middle frame 11 above the annular boss 13. The first limiting boss 14 and the second limiting boss 15 cooperate to form a rotating cavity. The annular boss 13 is rotatably disposed in the rotating cavity. The cooperation of the first limiting boss 14 and the second limiting boss 15 can provide installation space for the annular boss 13 without affecting its normal rotation, and can also prevent it from falling out, making it more stable during use.

[0018] The top of the annular boss 13 is provided with a first arc-shaped protrusion 16 that abuts against the bottom of the second limiting boss 15, and the bottom of the annular boss 13 is provided with a second arc-shaped protrusion 17 that abuts against the top of the first limiting boss 14. If the annular boss 13 is in direct contact, its contact surface is relatively large, thus overcoming a large frictional force. Using arc-shaped protrusions for contact can prevent relative wobbling and reduce the contact area, thereby reducing the energy consumption when overcoming frictional force. Of course, hemispherical protrusions can also be used for contact.
