Description

Technical Field

[0001] This utility model relates to the field of curling iron technology, specifically to a curling iron that can be attached to a hair dryer and curl hair in both directions. Background Technology

[0002] A curling iron is a DIY hair styling tool. Traditional curling irons have a single function, using a motor to rotate and heat up to curl hair, which can easily pull and damage the hair.

[0003] There are also curling irons on the market that attach to hair dryers and use airflow to curl hair. However, if users want to curl hair in both directions, they need to change to different left and right attachment heads, which is inconvenient.

[0004] An existing patent, application number 202420416225.4, discloses a method that changes the direction of the air outlet by adjusting the angle of the baffle and using a sealing element to block the air outlet that does not need to produce air, thus achieving bidirectional airflow for curling hair. However, this structure is relatively expensive in terms of both mold technology and production and processing costs. Furthermore, if any sealing element falls off, the entire curling iron needs to be replaced, which greatly increases the costs of molds, products, and after-sales service.

[0005] Therefore, it is necessary to provide a curling iron that can be attached to a hair dryer and curl hair in both directions. Utility Model Content

[0006] The main purpose of this invention is to provide a curling iron that can be attached to a hair dryer and curl hair in both directions, so as to solve the problems existing in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A curling iron that can be attached to a hair dryer and curl hair in both directions includes an air outlet shell and an air inlet shell. Each end of the air outlet shell is connected to an air inlet shell, and an air wall is connected to the air inlet shell. The air wall is provided with a ventilation structure.

[0009] The air outlet shell includes at least five arc-shaped structural components. The multiple arc-shaped structural components are arranged and connected in sequence along the central axis, and two adjacent arc-shaped structural components are connected to each other to form a connecting curved surface. An oblique air outlet is provided on the connecting curved surface, and the oblique air outlet is used to blow the hot air inside the air outlet shell obliquely.

[0010] Furthermore, the outer tangent surfaces of the curves at the connection points of two adjacent arc-shaped structural components are flush.

[0011] Furthermore, the ventilation structure includes a vent and a ventilation grille, the vent being disposed on the side wall of the wind wall and the ventilation grille being disposed at the end of the wind wall.

[0012] Furthermore, the tilt angle of each of the aforementioned angled air outlets is the same.

[0013] Furthermore, the width of the angled air outlet is 0.5mm-1mm.

[0014] Furthermore, the air inlet housing is provided with a positioning boss, which is adapted to the inner wall of the air outlet housing, and the air inlet housing is tightly connected to the air outlet housing through the positioning boss.

[0015] Furthermore, the air inlet housing is provided with a buckle for connecting the hair dryer.

[0016] Furthermore, one end of the air inlet shell is connected to a windshield shell, and a cover is connected to the windshield shell, forming a cavity between the windshield shell and the cover.

[0017] Furthermore, the windshield shell and the cover are connected by screws, and the air walls on the two air inlet shells are connected by screws.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The unique structure of the air vent, combined with the angled air outlet, controls the airflow to achieve a curling effect without pulling or damaging the hair.

[0020] 2. By setting air inlets at both ends of the air outlet shell, air can be blown in both directions, allowing the airflow to flow around the outer wall of the air outlet shell in a clockwise or counterclockwise direction, thus achieving bidirectional curling. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] Combination Figures 1-5 This utility model provides a curling iron that can be attached to a hair dryer and can curl hair in both directions, including an air outlet shell 1 and an air inlet shell 2. An air inlet shell 2 is connected to each end of the air outlet shell 1. An air wall 3 is connected to the air inlet shell 2 and a ventilation structure is provided on the air wall 3.

[0030] The air outlet shell 1 includes at least five arc-shaped structural components 11. The multiple arc-shaped structural components 11 are arranged in sequence along the central axis and connected to form the overall outline of the air outlet shell 1. The center of the circumferential arrangement is the axial center of the air outlet shell 1, and two adjacent arc-shaped structural components 11 are connected to form a connecting curved surface 12. An oblique air outlet 13 is provided on the connecting curved surface 12. The oblique air outlet is used to blow the hot air in the air outlet shell 1 obliquely to facilitate the movement of the hot air along the outer surface of the arc-shaped structural component 11. The oblique air outlet 13 has the same inclination angle, which allows the gas blown out from the oblique air outlet 13 to move stably around the outer wall of the air outlet shell 1.

[0031] When hot air is blown out through the angled air outlet 13 and passes through the arc-shaped structural component 11, the friction of the arc surface of the arc-shaped structural component 11 causes the hot air to flow along the outer convex side of the arc-shaped structural component 11, forming the Coanda effect. The hair naturally adheres and curls on the air outlet shell 1 with the hot air flow. Under the dual action of the hot air from the hair dryer and the heating of the air outlet shell 1 by the hot air, the hair is curled and shaped on the air outlet shell 1, thus achieving a curly hair effect.

[0032] The outer tangent surfaces of the curves at the connection points of two adjacent arc-shaped structural components 11 are flush; the width of the oblique air outlet 13 is 0.5mm-1mm, which can ensure the generation of a stable Coanda effect.

[0033] The ventilation structure includes a ventilation opening 31 and a ventilation grille 32. The ventilation opening 31 is disposed on the side wall of the wind wall 3, and the ventilation grille 32 is disposed at the end of the wind wall 3.

[0034] The ventilation structure is equipped with multiple ventilation openings 31 to ensure that the oblique air outlets 13 on the periphery of the air outlet shell 1 can deliver air evenly. As an optimization, the outer diameter of the wind wall 3 is smaller than the inner diameter of the air outlet shell 1, so that the air is evenly diffused in the air inlet shell 2 and dispersed into the air outlet shell 2 through the ventilation openings 31, and then blown out through the oblique air outlets 13 of the air outlet shell 2 to achieve the effect of uniform air delivery.

[0035] To prevent the air from the hair dryer blowing directly to the top and causing the curling iron to have no airflow near the hair dryer nozzle, the end of the air wall 3 is set with a ventilation grille 32. The ventilation grille 32 can disperse the air inside the curling iron, so that the end of the curling iron near the hair dryer can also have airflow, and the end of the curling iron away from the hair dryer also has sufficient airflow.

[0036] The air inlet shell 2 is provided with a positioning boss 21, which is adapted to the inner wall contour of the air outlet shell 1. The air inlet shell 2 is tightly connected to the air outlet shell 1 through the positioning boss 21.

[0037] The air inlet housing 2 is provided with a buckle 22, which is used to connect the hair dryer.

[0038] One end of the air inlet shell 2 is connected to the wind baffle shell 4, and the wind baffle shell 4 is connected to the cover 5. The wind baffle shell 4 and the cover 5 are connected by screws 6. The ends of the air walls 3 on the two air inlet shells 2 are provided with connecting holes, and the two air walls 3 are connected by screws 6. When curling hair, the air inlet shell 2 that is not connected to the hair dryer needs to be connected to the wind baffle shell 4 and the cover 5, so that the air outlet shell 1 forms an air cavity with air entering at one end and sealed at the other end, and hot air can be blown out normally from the slanted air outlet 13 of the air outlet shell.

[0039] As an optimization, after the cover 5 is closed, the end face of the wind deflector 4 furthest from the cover 5 is flush with the top surface of the air inlet shell 2's wind wall 3. This prevents the formation of a cavity after the cover is closed, which could cause whistling or hollow noise when air blows into the cavity. The wind deflector 4 and the cover 5 are fixedly connected by screws, forming a cavity. This cavity can block the hot air from the hair dryer from heating the cover 5, preventing burns during cover operation. Depending on the amount of hot air, heat insulation material, such as heat insulation cotton, can also be added to this cavity to more effectively block the hot air from the hair dryer from heating the cover 5.

[0040] When either end of the air inlet shell 2 is connected to the hair dryer, and the angled air outlet 13 of the air outlet shell 1 is already set to open in a clockwise or counterclockwise direction, after completing the unidirectional curling, the curling iron can be rotated 180° and the other end of the air inlet shell is connected to the hair dryer. The end of the curling iron not connected to the hair dryer is covered with a cap. At this time, the overall rotation direction and air outlet direction of the angled air outlet 13 of the air outlet shell 1 are opposite to the overall rotation direction and air outlet direction before rotating 180°, thus achieving the effect of bidirectional curling with one accessory.

[0041] This utility model is a curling iron that can be attached to a hair dryer in both directions. When in use, it can be connected to the hair dryer in both directions, so that the hair is attracted and curled in both directions due to the different air outlet directions when curling twice.

[0042] To ensure that the air outlet shell 1 remains unchanged and that both ends can be connected to external hair dryers and that the covers 5 can be closed at both ends, the clips 22 of the air inlet shells 2 at both ends that connect to the hair dryers must be in a rotational replication relationship. That is, after rotating one air inlet shell 180°, it can be consistent with the structure of the other air inlet shell 2, rather than being a left-right mirror symmetry relationship. The positioning bosses 21 inserted into both ends of the air outlet shell 1 must be in a mirror relationship. That is, the positioning bosses 21 installed on the two air inlet shells 2 at both ends of the air outlet shell 1 are symmetrically arranged left and right, rather than being in a rotational replication relationship.

[0043] A curling iron that attaches to a hair dryer and allows for bidirectional curling is simple in structure; simply changing the outer diameter of the air outlet shell 1 allows for the creation of curling irons in various sizes. It is also inexpensive, and the design of the external hair dryer can be adapted to different hair dryer nozzle structures, making it a versatile everyday accessory.

[0044] The air outlet shell 1 of the curling iron can be made of aluminum alloy, and it can achieve the effect of curling hair in both directions without any sealing or steering parts, which greatly reduces the production cost and production process.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
