Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to an air curling iron that prevents hair from getting stuck. Background Technology

[0002] Curling irons are a common tool for styling hair. They work by wrapping hair around a heated rod and using high temperature to deform the hair and create curls. However, using a heated component to change the shape of hair can easily cause irreversible damage. Furthermore, the exposed heating element can burn the user's skin. Therefore, a solution has been developed that uses hot air to heat the hair, achieving the same styling effect while reducing damage. For example, in the published technical document "CN111887565A, a curling iron assembly and a hair dryer using the same assembly," the hair is placed near the curling iron assembly, and the pressure difference causes the hair to adhere to the outer surface of the guide plate, creating curls under the influence of the exhaust airflow. This type of curling iron assembly achieves the curling function without causing irreversible damage to the hair.

[0003] Curling irons typically have soft guide plates on their surface to prevent burns to the hair. However, because there are gaps between the guide plates and the top and bottom ends of the curling iron, and the air curling iron attracts the hair to the guide plates, the hair may get stuck in the gaps when curling, resulting in a poor user experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air curling iron that prevents hair from getting stuck.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An anti-hair-snagging air curling iron, comprising:

[0007] An air outlet duct has an air passage formed inside it, and the air passage has an opening at one end of the air outlet duct. The surface of the air outlet duct is provided with a plurality of air outlets arranged in an array around its circumference.

[0008] The air deflectors are circumferentially spaced on the surface of the air outlet, and there are air outlets between adjacent air deflectors;

[0009] A cover is located at the other end of the air outlet duct, and works in conjunction with the air outlet duct to fix the guide plate to the surface of the air outlet duct.

[0010] The surface of the air outlet is provided with a sliding groove for the guide plate to slide, and the bottom of the air outlet is provided with a slot in the circumferential direction. The slot is set perpendicular to the sliding groove. The bottom of the guide plate extends downward to form a plug-in part. When the guide plate is installed in place, the plug-in part is inserted into the slot.

[0011] The upper surface of the guide plate is higher than the upper surface of the air outlet, and when the cover is fitted with the air outlet, the upper surface of the guide plate is in close contact with the lower surface of the cover.

[0012] The inner side of the guide plate is provided with a slider that is adapted to the slide groove.

[0013] The upper end of the slider extends upward to form a pressing part that mates with the cover.

[0014] The slider is provided with L-shaped hooks symmetrically on both sides, and the air outlet duct is provided with corresponding slots on both sides of the slide groove to cooperate with the L-shaped hooks.

[0015] There are several L-shaped hooks, which are spaced apart along the axis of the guide plate.

[0016] The air outlet includes a left air outlet and a right air outlet arranged symmetrically. The left air outlet and the right air outlet are provided with a sliding groove on the central axis, and the two sides of the guide plate extend towards the left air outlet and the right air outlet respectively.

[0017] The surface of the guide plate is arc-shaped, and the inner sides of both sides are set as guide surfaces. The projection of the guide surfaces overlaps with the air outlet at least partially to form an air outlet gap.

[0018] The height difference between the upper surface of the guide plate and the upper surface of the air outlet is 0.1 mm.

[0019] The beneficial effects of this utility model are as follows: by utilizing the cooperation between the upper and lower ends of the guide plate with the air outlet and the cover respectively, the plug part is interference-fitted with the air outlet to avoid gaps at the bottom, and the upper part, with its slightly higher design, is interference-fitted with the cover to avoid gaps on the upper side. Thus, when hair is wrapped around the surface of the guide plate by the wind, it will not be stuck by gaps. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] like Figure 1 As shown, this utility model provides an air curling iron that prevents hair from getting stuck. Specifically, it includes an air outlet 100 that can be fixedly connected to or detachably connected to the main body of the hair dryer. The surface of the air outlet is provided with several guide plates. After being installed in place, the guide plates are tightly fixed to the surface of the air outlet by the cover and the air outlet.

[0030] The air outlet duct has an air passage inside, and an opening communicating with the air passage is provided on one side. The surface of the air outlet duct 100 is provided with a plurality of air outlets 150 arranged in an array around the perimeter. The airflow enters the air passage through the opening and is discharged from the air outlet.

[0031] A plurality of guide vanes 200 are circumferentially spaced on the surface of the air outlet 100, and an air outlet 150 is provided between adjacent guide vanes 200. The guide vanes can be fixed to the air outlet by fastening, or as shown in this embodiment, they can be fixed by sliding fit and upper and lower end limiting.

[0032] A cover 300 is located at the other end of the air outlet 100 and cooperates with the air outlet 100 to fix the guide plate 200 to the surface of the air outlet 100. The cover can be fixed to the air outlet by means of threaded connection or by direct fastening. It can be a rotating fastening or a plug-in fastening.

[0033] The air outlet includes circumferentially arrayed arc-shaped plates 140, with air outlets formed between adjacent arc-shaped plates. In this embodiment, the air outlet includes a symmetrically arranged left air outlet and a right air outlet, with opposite airflow directions. The two outlets are connected at the middle position to form a sliding groove 130 for the guide plate 200 to slide. The bottom of the air outlet 100 is provided with a slot 110 circumferentially, and the slot 110 is perpendicular to the sliding groove 130. The inner side of the guide plate 200 is provided with a slider 230 that matches the sliding groove 130. During installation and fixing, the slider is placed in the sliding groove and slid along the sliding groove to install the guide plate.

[0034] The bottom of the guide plate 200 extends downward to form a plug-in portion 210. When the guide plate 200 is installed in place, the plug-in portion 210 is inserted into the slot 110, such as... Figure 2 and Figure 3 As shown, when the guide plate 200 moves into place, the plug part can be inserted into the slot and form an interference fit with the slot 110.

[0035] refer to Figure 2 and Figure 4 The upper surface 220 of the guide plate is higher than the upper surface 120 of the air outlet, and when the cover 300 is fitted with the air outlet 100, the upper surface 220 of the guide plate is in close contact with the lower surface of the cover 300. The height difference 'a' between the upper surface 220 of the guide plate and the upper surface 120 of the air outlet is 0.1 mm. This slightly higher design ensures that the cover presses firmly against the guide plate when fitted with the air outlet.

[0036] like Figure 5 As shown, the upper end of the slider 230 extends upward to form a pressing part 240 that mates with the cover 300. The pressing part is arc-shaped, and the height difference between it and the surface of the guide plate is adapted to the wall thickness of the cover. Thus, when the cover mates with the air outlet, the pressing part is placed on the inner side of the cover wall, thereby restricting its movement.

[0037] like Figure 6 As shown, the slider 230 is symmetrically provided with L-shaped hooks 260 on both sides, and the slide groove 130 of the air outlet duct 100 is provided with corresponding latches 160 on both sides to engage with the L-shaped hooks 260. There are several L-shaped hooks 260, which are spaced apart along the axial direction of the guide plate 200. By engaging with the latches, the L-shaped hooks can slide into the latches during sliding and form a snap-fit ​​with the latches, so that the longer guide plate can fit tightly against the surface of the air outlet duct.

[0038] The air outlet 150 includes a left air outlet and a right air outlet arranged symmetrically. A sliding groove 130 is provided on the central axis of the left air outlet and the right air outlet, and the two sides of the guide plate 200 extend toward the left air outlet and the right air outlet respectively.

[0039] The surface of the deflector plate 200 is curved, and the inner sides of both sides are configured as deflector surfaces 250. The projection of the deflector surface 250 at least partially overlaps with the air outlet 150 to form an air outlet gap 400. This makes the airflow direction counterclockwise or clockwise, thus enabling the airflow to automatically roll the hair onto the surface of the deflector plate.

[0040] The bottom of the guide plate is bent outward, so that the bottom diameter of the curling iron is larger than the top diameter, thereby changing the curliness of the hair strands.

[0041] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
