Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular to a movable reversible curling iron. Background Technology

[0002] As people's living standards improve, the demand for personal image and hairstyle management is increasing. Curling hair, as a common hairstyle, is favored by many users. Traditional curling tools mainly include curling irons and hair dryers. Among them, air curling irons, which use hot air to shape hair and create curls, have gradually become mainstream due to their ease of use and variety of styles.

[0003] Traditional air curling irons typically use a built-in fan to generate airflow, which is then directed onto the hair through an air guide structure, thus achieving the dual functions of heating and styling. However, the air guide structure of these traditional curling irons is often a fixed design, and its airflow direction cannot be adjusted. It can usually only achieve a unidirectional vortex effect. To achieve curling effects in different directions, some existing solutions employ complex mechanical structures or multiple air guide channels, resulting in a relatively complex overall structure. This not only increases manufacturing costs but may also affect the reliability and ease of use of the device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an air curling iron that is simple in structure, easy to operate, and can flexibly switch the air outlet direction to meet users' needs for different curling directions.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A reversible curling iron, comprising:

[0007] The air guide shell is cylindrical and has several first air guide ports and several second air guide ports circumferentially. The airflow from the first air guide ports is clockwise and the airflow from the second air guide ports is counterclockwise.

[0008] An air exchange frame is installed inside the air guide housing and can move up and down along the axial direction of the air guide housing. The air exchange frame is provided with several air outlets around its circumference. When the air exchange frame moves to the first position, the first air guide port can communicate with the air outlet, and the air outlet direction of the air guide housing is clockwise. When the air exchange frame moves to the second position, the second air guide port can communicate with the air outlet, and the air outlet direction of the air guide housing is counterclockwise.

[0009] The air exchange frame is cylindrical, and has several layers of air outlets and several layers of blocking parts. The air outlets and blocking parts are arranged in alternating layers along the axial direction of the air exchange frame, and the air outlets are circumferentially opened in the air outlets.

[0010] The air guide shell is provided with several layers of first air guides and several layers of second air guides in the axial direction. The first air guides and the second air guides are arranged in alternating upper and lower layers in the axial direction of the air guide shell. The first air guide is circumferentially opened in the first air guide and the second air guide is circumferentially opened in the second air guide.

[0011] The axial movement of the air exchanger within the air guide housing is the distance from when the air outlet is aligned with the first air guide to when the air outlet is aligned with the second air guide.

[0012] When the air exchanger moves to the first position, the air outlet is aligned with the first air guide and the first air guide is connected to the air outlet. At this time, the blocking part is aligned with the second air guide.

[0013] When the air exchanger moves to the second position, the air outlet is aligned with the second air guide and the second air guide is connected to the air outlet. At this time, the blocking part is aligned with the first air guide.

[0014] The axial length of the blocking part is greater than or equal to the axial length of the opening of the first air guide, and the axial length of the blocking part is greater than or equal to the axial length of the opening of the second air guide.

[0015] The movable reversible curling iron also includes a switching component for driving the air exchange frame to move up and down. The switching component includes a push-pull handle located at the upper end of the air guide housing, and the push-pull handle is connected to the upper end of the air exchange frame.

[0016] The upper end of the air exchange frame is provided with a connecting post that connects to the push-pull handle. The side of the connecting post is provided with a first groove and a second groove. The air guide shell is fixed with an elastic fastener that can cooperate with the first groove or the second groove. When the air exchange frame moves to the first position, the elastic fastener cooperates with the first groove. When the air exchange frame moves to the second position, the elastic fastener cooperates with the second groove.

[0017] The first groove and the second groove are provided on both sides of the connecting post, and the elastic fastener is an annular ring with an opening on one side.

[0018] The air exchange frame is equipped with a sealing ring that fits against the inner wall of the air guide shell.

[0019] The beneficial effects of this utility model are:

[0020] This curling iron features an air exchange frame that can move axially within the air guide housing. This allows the first air vent (clockwise airflow) and the second air vent (counter-clockwise airflow) on the air guide housing to selectively connect with the air outlet on the air exchange frame, thus achieving two different airflow directions: clockwise and counter-clockwise. Users can easily change the direction of the hot airflow by using a simple operation, such as pushing or pulling the switch, to achieve different curling effects.

[0021] By changing the relative position of the air guide shell and the air exchange frame, and by using simple axial movement in conjunction with the stacked air guide and air outlet structure, the air outlet direction can be switched. This eliminates the need for multiple independent air guide channels or complex linkage mechanisms, significantly simplifying the overall structure and improving the reliability and durability of the product.

[0030] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0031] This utility model provides a movable reversible curling iron. The core of the design is the cooperation between the axially movable air exchange frame 2 and the air guide shell 1, which enables flexible switching between clockwise and counterclockwise air outlet directions, thereby meeting different curling needs.

[0032] Reference Figure 1-2The air guide shell 1 is cylindrical in shape, with several first air guide ports 10 and several second air guide ports 11 evenly distributed on its circumferential cylindrical side. The airflow discharged from the first air guide ports 10 is clockwise, and the airflow discharged from the second air guide ports 11 is counterclockwise. Specifically, refer to... Figure 3 , Figure 5 Both the first air outlet 10 and the second air outlet 11 are arc-shaped outlets used to exhaust air to the right or left.

[0033] Reference Figure 7 The first air guide 10 forms several layers of first air guide parts 100 on the air guide shell 1, and the second air guide 11 forms several layers of second air guide parts 110 on the air guide shell 1. The first air guide parts 100 and the second air guide parts 110 are arranged along the axial direction of the air guide shell 1 and are arranged in alternating layers, that is, from top to bottom, they are first air guide parts 100, second air guide parts 110, first air guide parts 100..., to ensure that only the first air guide part 100 or the second air guide part 110 can be aligned with the air outlet of the air exchange frame 2 at the same time.

[0034] Reference Figure 7 The air exchange frame 2 is also cylindrical and can move along the axial direction (vertical direction) of the air guide shell 1. Its hollow interior allows for the passage of either cold or hot air, with the hot air source being the heating and fan module built into the curling iron. Specifically, the air exchange frame 2 includes an air outlet 24 and a blocking part 25. The air outlet 20 is circumferentially opened in the air outlet 24 to guide the internal airflow to the corresponding air guide port of the air guide shell 1. The blocking part 25 has no circumferential opening and is a closed tube wall used to block the air guide port of the air guide shell 1. When the air outlet 24 is not aligned with the target air guide, the blocking part 25 covers the air guide port to prevent air leakage. The air outlet 24 and the blocking part 25 are arranged in alternating layers along the axial direction of the air exchange frame 2, i.e., from top to bottom, they are air outlet 24, blocking part 25, air outlet 24…, corresponding to the spacing pattern of the first air guide 100 and the second air guide 110 of the air guide shell 1.

[0035] Reference Figure 3 , Figure 5 and Figure 8The switching component 3 includes a push-pull handle 31, which is connected to a connecting post 21 at the upper end of the air exchanger 2. By pushing and pulling the push-pull handle 31, the user can move the air exchanger 2 up and down along the axial direction of the air guide housing 1, thereby switching the alignment state of the air outlet 24 with the first air guide 100 or the second air guide 110. To ensure the stability of the position after switching, the first groove 210 and the second groove 211 on the side of the connecting post 21 respectively cooperate with the elastic fastener 22 fixed inside the air guide housing 1. When the air exchanger 2 moves to the first position where the air outlet 24 is aligned with the first air guide 100, the elastic fastener 22 engages with the first groove 210; when the air exchanger 2 moves to the second position where the air outlet 24 is aligned with the second air guide 110, the elastic fastener 22 engages with the second groove 211 to prevent the air exchanger 2 from sliding accidentally. Meanwhile, the engagement of the elastic fastener 22 with the first groove 210 or the second groove 211 provides a clear "locking feel", allowing the user to determine whether the airflow is clockwise or counterclockwise by touch.

[0036] This utility model achieves the switching between two types of air guiding states by axially moving the air exchange frame 2 within the air guide housing 1. Specifically:

[0037] When the user pushes the push-pull handle 31 down to the first position, the air outlet 24 of the air exchange frame 2 aligns with the first air guide 100 of the air guide shell 1, so that the air outlet 20 is connected to the first air guide 10. At the same time, the blocking part 25 of the air exchange frame 2 aligns with the second air guide 110 of the air guide shell 1, blocking the second air guide 11. At this time, the hot air generated by the built-in fan of the curling iron enters the interior of the air exchange frame 2 through the internal air duct, and is then discharged through the air outlet 24 and the first air guide 10, forming a clockwise vortex, thereby assisting the hair to form a clockwise curling effect.

[0038] When the user pulls the push-pull handle 31 upward to the second position, the air outlet 24 of the air exchange frame 2 aligns with the second air guide 110 of the air guide housing 1, so that the air outlet 20 and the second air guide 11 are connected; at the same time, the blocking part 25 of the air exchange frame 2 aligns with the first air guide 100 of the air guide housing 1, blocking the first air guide 10. At this time, hot air is discharged through the air outlet 24 and the second air guide 11, forming a counterclockwise vortex, thereby assisting the hair to form a counterclockwise curling effect.

[0039] Furthermore, the axial movement stroke of the air exchanger 2 within the air guide housing 1 is designed to be the distance the air outlet 24 travels from alignment with the first air guide 100 to alignment with the second air guide 110, i.e., the interval distance between the two air guides, ensuring that only one set of air outlets 24 is fully aligned with the target air guide after each movement. The axial length of the blocking part 25 is greater than or equal to the opening axial length of the first air guide 10 or the second air guide 11, ensuring that non-target air guides are completely blocked and preventing airflow interference.

[0040] In summary, the movable reversing curling iron of this utility model achieves precise switching of air outlet direction through the relative movement of the air guide shell 1 and the air exchange frame 2, with a simple mechanical structure. This solves the problems of monotonous styling and high cost of complex mechanical structure caused by the fixed air guide structure of traditional curling irons, while ensuring the convenience of operation and the reliability of use.
