Description

Technical Field

[0001] This utility model belongs to the field of hair care technology, specifically relating to the air outlet structure of a curling iron. Background Technology

[0002] When using a curling iron, hair needs to be wrapped around it, but the wrapping and fixing effect is not ideal and it is easy to slip off. Therefore, existing curling irons use airflow to help the hair wrap around the barrel. However, in the existing technology, the size of the air outlet that controls the airflow is not matched with the position of different sections of hair, resulting in flat roots and overly curled ends, which affects the overall style of the curl. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides an air outlet structure for a curling iron, aiming to solve the problem in the prior art where the air outlet volume of the curling iron is not matched with the roots, middle and ends of the hair, resulting in poor styling effect.

[0005] (2) Technical solution

[0006] This utility model provides an air outlet structure for a curling iron, including a support, a barrel, and an end cap. The barrel is sleeved on the support, and the end cap is connected to the ends of the support and the barrel. The support has a flow channel, and the barrel has at least one air outlet area along the axis L1. The air outlet area has airflow holes that communicate with the flow channel. A plurality of airflow holes are spaced apart along the axis L1 and gradually increase in size from both ends of the air outlet area toward the middle.

[0007] Furthermore, the airflow holes in the same radial direction are arranged in a ring array along axis L1 and are of the same size.

[0008] Furthermore, the airflow holes arranged along the axis L1 in the air outlet area are arranged symmetrically in the middle of the air outlet area.

[0009] Furthermore, the cylinder body is provided with two air outlet zones along axis L1.

[0010] Furthermore, the airflow hole is circular, elliptical, or polygonal in shape.

[0011] Furthermore, the airflow hole extends along the axis L1.

[0012] Furthermore, the airflow holes extend radially around the cylinder.

[0013] Furthermore, the cylindrical body is a cylinder, an elliptical cylinder, or a polygonal cylinder.

[0014] Furthermore, the cylinder body has an anti-scalding zone at at least one end, and the airflow hole is located outside the anti-scalding zone.

[0015] Furthermore, the anti-scalding zone is provided at both ends of the cylinder.

[0016] Furthermore, the bracket is provided with a connector, and the connector is provided with an abutment portion adapted to the cylinder body. One end of the cylinder body abuts against the abutment portion, and the other end abuts against the end cap.

[0018] Furthermore, the guide plate is arranged in a spiral shape along the axis L1.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] By designing the airflow holes to gradually increase in size from both ends of the barrel towards the middle, the airflow from the middle section is greater than that from the ends.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-4 As shown, this utility model provides an air outlet structure for a curling iron, including a support 1, a barrel 2, and an end cap 3. The barrel 2 is sleeved on the support 1, and the end cap 3 is connected to the end (i.e., the rear end) of the support 1 and the barrel 2. The support 1 has a flow channel 11, and the barrel 2 has at least one air outlet area 21 along the axis L1. The air outlet area 21 has airflow holes 22 communicating with the flow channel 11. A plurality of airflow holes 22 are spaced apart along the axis L1 and gradually increase in size from both ends of the air outlet area 21 towards the middle. Since most of the hair is concentrated in the middle when wrapped around the barrel 2 during use, this design is suitable for use in curling irons. The hair in the middle section is thicker than that at the ends, requiring more heat and airflow for styling. Therefore, increasing the diameter of the airflow hole 22 in the middle section can adjust the airflow, effectively balance the axial air pressure distribution, avoid local overheating, make the airflow more uniform, and better meet the heat requirements when curling different parts of the hair, thus making the overall curling effect better. At the same time, it can also improve the efficiency of curling. In this utility model, the airflow blown out from the airflow hole 22 flows on the outer surface of the cylinder 2. The flowing airflow generates a wall adhesion effect, which can also adhere the hair to the outer surface of the cylinder 2 and prevent the hair from slipping off.

[0034] Furthermore, such as Figure 5 As shown, the airflow holes 22 in the same radial direction are arranged in a ring array along the axis L1 and are the same size. This can reduce airflow resistance, make the airflow evenly distributed to the entire surface of the curling tube, make the airflow of the tube 2 more uniform, avoid local overheating or uneven styling, and at the same time, avoid the situation where the hair ends are too curled and the hair roots are flat due to excessive airflow at both ends.

[0035] Furthermore, the airflow holes 22 arranged along the axis L1 in the air outlet area 21 are arranged symmetrically with respect to the middle of the air outlet area 21. The symmetry line of the middle of the air outlet area 21 is L2. All the airflow holes 22 in the air outlet area 21 are arranged symmetrically with respect to L2 as the axis of symmetry, making the cylinder 2 more aesthetically pleasing and easier to process.

[0036] In some embodiments, such as Figure 6 As shown, the cylinder 2 has two air outlet zones 21 along the axis L1, which are suitable for curling shorter hair. However, regardless of the number of air outlet zones 21, the airflow holes 22 at both ends of the cylinder 2 are small holes so that the airflow is concentrated in the middle position, avoiding excessive temperature at the roots and ends of the hair during curling, which would cause the ends to curl too much or the roots to flatten. This makes the curling effect better and more uniform when people use this utility model.

[0037] In some embodiments, such as Figure 5 , Figure 7 As shown, the airflow hole 22 can be irregularly shaped such as a circle, ellipse or polygon, with a variety of shapes to meet different user preferences and improve the user experience.

[0038] In some embodiments, such as Figure 8 In Figure 8 As shown in Figure a, the airflow hole 22 extends along the axis L1. When the shape of the airflow hole 22 is elliptical, the major axis L3 of the ellipse is parallel to L1.

[0039] In some embodiments, such as Figure 8 In Figure 8 As shown in b, the airflow hole 22 extends radially around the cylinder 2. When the shape of the airflow hole 22 is elliptical, the major axis L3 of the ellipse is perpendicular to L1.

[0040] In some embodiments, the cylindrical body 2 is a cylinder, an elliptical cylinder, or a polygonal cylinder. In this case, the shape of the outer periphery of the support 1 and the end cap 3 is adapted to the shape of the cylindrical body 2. Considering the convenience of use and processing, as well as the stability of the shape, in this embodiment, the cylindrical body 2 is preferably a cylinder.

[0041] Furthermore, such as Figure 3As shown, at least one end of the cylindrical body 2 is provided with an anti-scalding zone 23, and the airflow hole 22 is located outside the anti-scalding zone 23. The anti-scalding zone 23 is used for assembling other components. Therefore, placing the airflow hole 22 outside the anti-scalding zone 23 can prevent the connection between the cylindrical body 2 and other components from being affected by hot air, resulting in excessively high temperatures, which could damage other components or cause unstable connections and loosening. In this embodiment, both ends of the cylindrical body 2 are provided with the anti-scalding zone 23.

[0042] Furthermore, such as Figure 4 , Figure 9 As shown, the front end of the bracket 1 is provided with a connector 12, and the connector 12 is provided with an abutment portion 121 adapted to the cylinder 2. One end of the cylinder 2 is inserted into the end of the bracket 1 and abuts against the abutment portion 121, and the other end abuts against the end cap 3. The end cap 3 is then connected and fixed to the bracket 1. The connection method can be snap-fit, screw-fit, or adhesive, etc. In this embodiment, the end of the bracket 1 is provided with a threaded groove 15, and the end cap 3 is provided with a screw hole 31. A screw passes through the screw hole 31 and is threadedly connected to the threaded groove 15, thereby... The connection between the end cap 3 and the bracket 1 is achieved, thereby limiting and fixing the cylinder 2 between the end cap 3 and the connector 12, which facilitates assembly and ensures the stability of the connection. In addition, after the end cap 3 is screwed to the bracket 1, the end of the flow channel 11 can be sealed, so that the airflow can only be discharged from the airflow hole 22, improving the utilization rate of the airflow. The connector 12 is provided with a fixing structure for use with other parts (such as power supply, fan, handle, etc.). Since this part is not within the main protection scope of this utility model, it will not be described in detail here.

[0043] Specifically, such as Figure 4 , Figure 10 As shown, the bracket 1 includes several support rods 13 and guide plates 14. Each support rod 13 extends along the axis L1 and surrounds to form the bracket 1. The guide plates 14 are obliquely connected between two adjacent support rods 13 and are arranged at intervals along the axis L1, thereby forming several air outlet spaces 16. The air outlet spaces 16 are connected to the airflow holes 22. The guide plates 14 have air guiding surfaces 141 facing the air inlet end of the cylinder 2. Preferably, the air guiding surfaces 141 can be flat, curved, or other surfaces of different shapes that can guide airflow. When the airflow reaches each of the air guiding surfaces 141, the air guiding surfaces 141 can change the flow direction of the airflow, causing the airflow to flow out towards the airflow holes 22, thereby acting on the hair. The arrangement of multiple guide plates 14 can more evenly balance the airflow on the outer surface of the cylinder 2, so that the styling effect is optimal.

[0044] Furthermore, the guide plate 14 is spirally arranged along the axis L1, which allows the airflow to be blown out in a spiral shape and form a hot air layer around the hair, so that the heat can penetrate evenly from all sides of the hair strands. This avoids the defects of uneven heating on one side caused by traditional direct blow dryers, which can easily damage the hair or make the style not last long. At the same time, the spiral airflow generates rotational force inside the cylinder 2, which can drive the hair strands to naturally wrap around the cylinder 2, reducing the pulling of manual winding.

[0045] Preferably, since most of the airflow will be discharged from the airflow hole 22 at the front end or middle of the cylinder 2, the airflow to the end of the cylinder 2 is relatively small. Therefore, the gap D1 between two adjacent guide plates 14 near the two ends of the support 1 is larger than the gap D2 between two adjacent guide plates 14 in the middle position. This can increase the airflow volume of the end airflow hole 22 and further increase the uniformity of the fluid flowing out of the airflow hole 22.

[0046] The following is a detailed explanation of the working principle of this utility model:

[0047] In use, the hair is wrapped around the barrel 2. When the airflow enters the flow channel 11, under the guidance of the guide plate 14, the airflow will be blown out through the air outlet space 16 and the airflow hole 22. Since the guide plate 14 is inclined, the airflow can be blown out in a spiral shape and surround the hair to form a hot air layer. While achieving hair perming, it also has an adsorption force on the hair, making the hair wrapped more firmly. Since the airflow hole 22 gradually increases from both ends of the barrel 2 to the middle, the airflow from both ends is less than the airflow from the middle position. This allows more heat to be concentrated in the middle position where there is more hair, so as to regulate the heat of the hair roots and ends, prevent overheating that causes the hair ends to curl too much, the hair roots to flatten, or burn the scalp, and thus make the blown airflow act more evenly on the hair.

[0048] The innovation of this invention lies in setting the airflow holes to gradually increase in size from both ends of the barrel towards the middle. This allows the airflow from the middle of the barrel to be greater than that from the ends, thus ensuring that the thicker middle section of the hair receives more heat, improving styling efficiency. Meanwhile, the roots and ends receive less heat, providing protection for them. Furthermore, by adjusting the size of the airflow holes, the airflow volume is changed, allowing the airflow to be matched to the hair at different positions on the barrel during curling, resulting in a better overall styling effect.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
