Embodiments of the present invention

In order to describe in detail the technical content, the achieved objectives and effects of the present invention, the following description will be given in conjunction with the embodiments and the accompanying drawings.

The most critical idea of the present invention is that a plurality of wind guide vanes are used to form the winding part, and each wind guide vane has an independent cavity as a fluid channel to independently discharge wind, and the diversion effect is better.

The air inlet corresponds to the air duct of the handle; the outer wall is a partial cylindrical structure; and the side wall is provided with a plurality of air outlets.

An air guiding channel is formed between the side wall and the air guiding wall on the adjacent air guiding blade; the side wall extends along the outer wall direction to form an extension, and the extension is part of the outer surface of the winding part, An air outlet channel is formed between the extension part and the outer wall, and the air outlet channel communicates with the air guide channel, and the air outlet channel extends in a direction tangent to the outer surface of the winding part.

From the above description, the beneficial effect of the present invention is that after the winding part is installed on the handle of the automatic hair curler, the handle provides air flow into the cavity of the wind guide blade in the winding part, and the air flow passes through the air outlet on the wall of the wind guide blade. After entering the air guide channel with diversion and air outlet functions, it will be discharged at a high speed outward in a certain direction. The high-speed airflow will revolve along the winding part to form high-speed rotating wind. According to the Venturi effect, negative pressure will be generated near the high-speed rotating wind. , So that the hair is absorbed and wound on the surface of the winding part, and the hair is wound and sculpted.

Further, the air outlet is located on the side wall at a position close to the center of the winding part, and the air guide channel extends from the position of the air outlet to the air outlet channel.

It can be seen from the above description that the above structure allows the airflow output from the cavity to be guided once through the air guiding wall and then discharged from the air guiding channel to ensure the stability of the airflow. Since the fluid flow direction in the cavity is perpendicular to the direction of the air outlet, if the air is directly exhausted through the air outlet, turbulence is likely to occur.

It can be seen from the above description that the above structure allows the air flow output from the air outlet to pass through a certain stroke in the guide channel before being discharged from the air outlet channel, which is more conducive to controlling the flow direction of the air flow, and is more conducive to avoiding turbulence.

Further, the surface of the side wall located in the air guide channel is provided with a plurality of baffles extending toward the air guide wall of the adjacent air guide vanes, and a space between the two baffles is connected to one The air outlet.

As can be seen from the above description, the structure of the multi-baffle plate allows the multiple airflows output from each air outlet to be isolated one by one, and then pass through a section of air duct space and then discharge outwards, avoiding the turbulence caused by the interaction between the airflows. To ensure that the neat high-speed airflow is finally discharged from the air guide channel.

Further, the automatic hair curler according to claim 1, wherein the outer wall is provided with a limiting rib located on the extension path of the extension part.

It can be seen from the above description that the ribs can limit the position of the air guide vanes in the circumferential direction, so as to avoid the displacement of the air guide vanes after long-term use, which will cause the volume of the air guide channel to change and fail to generate airflow that meets the requirements of use.

Further, the winding part includes a head end and a tail end, the head end is provided with a cover, the cover closes the closed end of the cavity, and the tail end is the cavity as the air inlet. At one end, the tail end is used to connect the handle of the automatic hair curler.

It can be seen from the above description that the winding part composed of a plurality of wind guide vanes can be fixedly installed through the cover body at the head end and the connecting handle at the tail end.

Further, it further includes a joint piece, the joint piece is installed on the tail end through a connecting structure, and the winding part is connected to the handle of the automatic hair curler through the joint piece.

It can be seen from the above description that the joint member can better fix a plurality of wind guide vanes, and allow the winding part to be connected to the handle after the fixing is completed.

Further, the cross-sectional area of the two ends of the winding part is larger than the cross-sectional area of the middle part of the winding part.

It can be seen from the above description that the shape of the winding part of "large at both ends, small in the middle" can make the input airflow concentrate as far as possible to the middle of the winding part, which can prevent the hair from leaving the curling tube during the curling operation, and at the same time, the discharged airflow brings the hair close to the middle. The position is more convenient for curling hair.

Further, the air guide vanes are provided with six air guide vanes, and the six air guide vanes are annularly spliced to form the winding part.

It can be seen from the above description that the above structure facilitates the assembly of the curling iron and is beneficial to reduce the cost.
