Description

TECHNICAL FIELD

[0001] The utility model belongs to curling iron technical field, concretely relates to a kind of high-efficiency air outlet structure and its curling device. BACKGROUND

[0002] Curling iron is a hair styling equipment, and the traditional curling iron only relies on heating element shaping, and the high temperature of the heating element can easily cause concentrated damage to hair. Therefore, a hair styling tool integrating hair dryer and curling function appears in the market, which combines the hot air output of hair dryer and the styling design of curling iron, and can shape curly or wavy hairstyle while drying hair. For example, in the prior art, the Chinese patent with publication number CN201164141Y discloses a hair dryer for curling, which is provided with a curling iron with teeth at the air outlet, and a plurality of rows of air outlet holes are arranged on the curling iron to reduce the problem of high temperature damage to hair caused by traditional curling iron.

[0003] However, in actual use, the air outlet holes of the curling iron in the above-mentioned hair dryer are small and have small air volume, which can not quickly and uniformly heat the hair during curling. Users need to repeatedly wind the same strand of hair, which not only wastes time but also may damage the hair due to local overheating, resulting in dry and split hair. Moreover, the small air outlet holes are easy to accumulate dust and hair debris during long-term use, which not only affects the smoothness of air outlet but also is difficult to clean and breed bacteria.

[0004] In view of the problem of small air outlet holes, some existing technologies have been improved by increasing the air outlet to increase the air volume, but new problems arise in curling application. The air outlet holes of these curling irons are designed too large, which causes the hot air to quickly spread after leaving the air outlet hole, and only a small amount of hot air can contact the hair. The hot air is difficult to concentrate on the hair, which cannot effectively change the shape of the hair, reduces the curling efficiency, and cannot meet the user's demand for efficient curling.

[0067] Example 1

[0068] like Figures 1-11 As shown, this embodiment provides a high-efficiency air outlet structure for use with a curling iron, including:

[0069] The inner cylinder 1 is hollow inside, with an air inlet at the bottom and multiple air outlets 11 on the side wall;

[0070] The outer cylinder 2 is fitted outside the inner cylinder 1, and the top of the outer cylinder 2 is rotatably connected to the top of the inner cylinder 1 through a rotating assembly; the outer surface of the side wall of the outer cylinder 2 is provided with multiple equally spaced protruding ribs 24.

[0071] The air guide assembly is arranged on the outer cylinder 2 and is used for guiding air flow to be discharged. The air guide assembly comprises a plurality of air guide plates 25, a first air duct and a second air duct. The air guide plates 25 are arranged between adjacent convex edges 24. The first and second air ducts are adapted to the air outlet hole 11 through rotation. The first air duct is formed between one side of the convex edge 24 and the front air guide plate 25, and the second air duct is formed between the other side of the convex edge 24 and the rear air guide plate 25.

[0072] The outlet of the first and second air ducts is extended and narrowed, and is alternately distributed along the outer circumference of the outer cylinder 2.

[0073] On the outer side wall of the outer cylinder 2, a plurality of air guide plates 25 form a first circle layer, and a plurality of convex edges 24 form a second circle layer. The diameter of the second circle layer is smaller than that of the first circle layer.

[0074] The convex edge 24 of the second circle layer forms a recess between two adjacent air guide plates 25. The hair placed in the recess can enjoy more concentrated air flow, which helps to improve the effect on the hair and make the hair more evenly and efficiently heated and affected by the air flow during the curling process, thereby improving the curling quality.

[0075] The outer side wall of the inner cylinder 1 is provided with a sealing baffle 13. The sealing baffle 13 is in sliding contact with the inner side wall of the outer cylinder 2 and is used for closing or opening the inlet of the first and second air ducts.

[0076] Firstly, the efficient air outlet structure effectively improves the air outlet amount through the design of a plurality of air outlet holes 11 on the side wall of the inner cylinder 1 and the air guide assembly on the outer cylinder 2. Meanwhile, the outlet of the first and second air ducts is extended and narrowed, so that the air flow can be transported from the air duct of the second circle layer to the two sides of the air guide plate 25 of the first circle layer for output, realizing the reasonable guidance of the air flow and helping to concentrate the hot air to the hair to ensure that the hair can be quickly and evenly heated, thereby improving the curling efficiency.

[0077] Secondly, the air guide plate 25, the first air duct and the second air duct in the air guide assembly are adapted to the air outlet hole 11 through rotation, so that the hot air can flow along the predetermined path, reducing the diffusion of the hot air and the heat loss. This design ensures that the hot air can directly act on the hair, improving the utilization rate of heat energy.

[0078] Thirdly, the outer cylinder 2 is rotationally connected with the inner cylinder 1 through the rotation assembly. The user can adjust the angle of the outer cylinder 2 according to the needs, so as to change the flow direction of the hot air and the adaptation of the air outlet hole 11 and the air duct. This design enhances the flexibility and convenience of use.

[0079] Finally, compared with the narrow and easy to accumulate dust and hair debris of the air outlet hole 11 in the traditional curling iron, the air outlet hole 11 and the air duct design in the high-efficiency air outlet structure are more spacious, and the structure of the air deflector 25 and the convex rib 24 is also convenient for cleaning and maintenance. This helps to maintain the hygiene and performance stability of the curling iron and prolongs the service life.

[0080] Specifically, the side wall of the outer barrel 2 is provided with first ventilation holes 27 and second ventilation holes 26, and a plurality of first ventilation holes 27 are arranged in the same row to form a first air duct, and a plurality of second ventilation holes 26 are arranged in the same row to form a second air duct.

[0081] The first and second air ducts help guide the airflow to flow along a predetermined path, improving the conduction efficiency and concentration of hot air, thereby enhancing the curling effect.

[0082] Specifically, the number of air deflectors 25 is consistent with the number of convex ribs 24, which ensures the close cooperation between the air deflectors 25 and the convex ribs 24, effectively guides the airflow to be discharged, reduces the turbulence and diffusion of the airflow, and improves the utilization rate of hot air.

[0083] More specifically, six air deflectors 25 are provided, and six convex ribs 24 are provided.

[0084] Specifically, each ventilation hole and air outlet hole 11 is in the shape of a long strip and extends along the axial direction of the outer barrel 2 and the inner barrel 1, respectively, which is beneficial to increase the length and area of the hole, helps the airflow to pass more smoothly, improves the air volume and the uniformity of hot air, and enables the hair to be heated more quickly and evenly.

[0085] The hole wall of each ventilation hole is provided with a flow guide slope, and the inclination direction of the flow guide slope is consistent with the airflow direction of the corresponding air duct, which further optimizes the flow path of the airflow, reduces the resistance and vortex of the airflow, improves the conduction efficiency and stability of the hot air, and thereby enhances the overall performance of the curling iron.

[0086] Specifically, each air deflector 25 is provided with a first arc segment 252 on the side close to the air duct outlet, and the first arc segment 252 protrudes towards the convex rib 24.

[0087] Each air deflector 25 is also provided with a second arc segment 253 on the side close to the air duct outlet, and the second arc segment 253 is recessed away from the convex rib 24, and the second arc segment 253 and the first arc segment 252 are arranged in sequence along the direction of the output airflow.

[0088] The first and second arc segments 253 are arranged to enable the air deflector 25 to better guide the airflow and reduce the turbulence and diffusion of the airflow. The first arc segment 252 protrudes towards the protruding ridge 24, which helps to concentrate the airflow towards the air duct outlet; the second arc segment 253 is recessed away from the protruding ridge 24, which helps to further adjust the flow direction and speed of the airflow, so that the airflow passes through the air duct outlet more smoothly.

[0089] Specifically, one side of each protruding ridge 24 is provided with an inverted V-shaped structure, which includes two symmetrical air guide inclined surfaces 241; the two air guide inclined surfaces 241 intersect at the middle of the inverted V-shaped structure to form a smooth vertex, and then extend to both sides and incline downward until they meet the edge of the inner wall of the outer cylinder 2.

[0090] The design of the inverted V-shaped structure helps to disperse and guide the airflow to both sides, increasing the contact area of the airflow and improving the conduction efficiency of the hot air. At the same time, the middle part of the inverted V-shaped structure forms a smooth vertex, reducing the resistance of the airflow, so that the airflow can pass through more smoothly.

[0091] Specifically, the gap between the first arc segment 252 and the air guide inclined surface 241 gradually narrows along the direction of the airflow, forming a smooth first wedge-shaped channel 28.

[0092] The design of the first wedge-shaped channel 28 prolongs the output channel of the airflow, so that the airflow can accelerate and form a high-speed rotating airflow when passing through the channel. The high-speed rotating airflow helps to improve the concentration of the hot air, so that the hair can be heated more quickly and uniformly, thereby enhancing the curling effect.

[0093] Specifically, each sealing baffle 13 is provided with a sealing strip 131 at both ends of the sliding contact surface, and each sealing strip 131 extends towards the outer cylinder 2.

[0094] Each sealing strip 131 is arranged along the length of the sealing baffle 13, and the side in contact with the outer cylinder 2 is provided with a transition arc surface.

[0095] The sealing strip 131 helps to enhance the sealing between the sealing baffle 13 and the outer cylinder 2, to ensure that the airflow can be concentrated and discharged from the pre-designed air duct.

[0096] Specifically, the air deflector 25 is detachably connected with the outer cylinder 2.

[0097] More specifically, the air deflector 25 is provided with a plurality of buckles 251, and the outer cylinder 2 is provided with buckle grooves 22 that are buckled with the buckles 251, and the air deflector 25 is clamped between two protruding ridges 24.

[0098] In the embodiment, the air deflector 25 is detachably connected with the outer cylinder 2 by the clamping connection of the buckle 251 and the buckle groove 22, which is not only convenient to install, but also convenient to disassemble, clean or replace the air deflector 25, thereby reducing the maintenance cost and prolonging the service life of the air direction switching mechanism.

[0099] The top of each air deflector 25 is connected with the top of the outer cylinder 2 by a fastener, which is more firm than the adhesive bonding method.

[0100] Specifically, the fastener includes a bolt or a bolt that penetrates the top of the air deflector 25 and the top of the outer cylinder 2.
