Description

Technical Field

[0001] This utility model belongs to the field of hair curling tool technology, and specifically relates to a hair curling tool. Background Technology

[0002] As a household appliance widely used in the hairdressing industry, curling irons achieve hair curling and styling functions through heating elements or airflow. They usually have a filter at the air inlet to block stray hairs from entering the internal motor and prevent clogging or damage. The filter of traditional curling irons is mostly fixed inside the machine body and needs to be cleaned regularly to maintain smooth airflow. Traditional curling iron filters often use a rigid, fixed design, embedded inside the machine body. After long-term use, the accumulation of hair clippings can obstruct airflow. If users need to clean them, they have to remove the protective mesh cover and use additional auxiliary tools (such as a cleaning brush) to remove impurities from the filter surface. This process not only increases maintenance time and costs but is also cumbersome and affects ease of use. Utility Model Content

[0003] In view of this, the present invention provides a hair curler that integrates the cleaning brush and protective mesh cover into a single design. By utilizing the synergistic effect of limiting components and sealing elements, it achieves a combination of cleaning function and quick disassembly, reducing reliance on external tools and significantly improving ease of operation and maintenance efficiency. It ensures a stable connection of the protective mesh cover while supporting quick disassembly, enhancing reliability. The sealing rubber ring can seal the area where the cleaning brush is located, preventing dust accumulation and maintaining cleanliness.

[0004] To solve the above-mentioned technical problems, this utility model provides a hair curler, including a body and a plurality of curling comb teeth evenly arranged at its curling end. A fan is provided in the inner cavity of the handle end of the body, and a heating tube is provided in the middle of the inner cavity of the curling end of the body. A filter screen is provided at the air inlet end of the body, and a protective net cover is movably installed at the air inlet end of the body. The filter screen is located inside the protective net cover. A plurality of cleaning brushes are evenly distributed in a ring at the open end of the inner arc surface of the protective net cover. A sealing element is provided between the body and the protective net cover, and a limiting component is also provided between the body and the protective net cover. That is, by integrating the cleaning brushes and the protective net cover into one design, and utilizing the synergistic effect of the limiting component and the sealing element, the cleaning function and quick disassembly and assembly are combined, reducing the dependence on external tools, significantly improving the ease of operation and maintenance efficiency, ensuring the stable connection of the protective net cover, supporting quick disassembly and assembly, and enhancing the reliability of use. The sealing rubber ring can seal the area where the cleaning brushes are located to prevent dust accumulation and maintain cleanliness. The sealing element includes a sealing rubber ring located on the outer arc surface of the machine body near the filter screen. The sealing rubber ring abuts against the inner arc surface of the protective mesh cover, thus achieving the sealing function.

[0005] Several cleaning brushes are located within an annular cavity formed by the body, protective mesh cover, and sealing rubber ring, thus maintaining the cleanliness of the cleaning brushes.

[0006] The diameter of the body furthest from the curling end is the same as the diameter of the protective mesh, ensuring user comfort when holding it.

[0007] The limiting component includes a limiting slot located on the inner arc surface of the protective mesh cover. The inner arc surface of the protective mesh cover is provided with a limiting protrusion that cooperates with the limiting slot, thereby realizing the installation and fixation of the protective mesh cover.

[0008] The limiting slot is L-shaped, which enables the limiting protrusion to be fixed.

[0009] The limiting component also includes a guide groove set on the outer arc surface of the limiting protrusion. A limiting ball head is slidably connected in the guide groove. The limiting ball head is movably inserted into the ball groove corresponding to the inner wall of the limiting slot. An elastic element is provided between the limiting ball head and the guide groove, thus realizing secondary limiting of the protective net cover.

[0010] The elastic element includes a spring disposed between the outer arc surface of the limiting ball head and the inner wall surface of the guide groove, which can provide elastic force to the limiting ball head.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. When the filter needs cleaning, the user simply removes the protective mesh cover using the limiting component, then moves it back and forth while rotating it. This allows the cleaning brushes, distributed in a ring on the inner arc surface, to clean the filter surface, removing blockages and maintaining airflow efficiency. By integrating the cleaning brushes and protective mesh cover into a single design, and utilizing the synergistic effect of the limiting component and seals, the cleaning function is combined with quick disassembly and assembly, reducing reliance on external tools and significantly improving ease of operation and maintenance efficiency. After cleaning, the user installs the protective mesh cover to the main body using the limiting component, ensuring a secure installation. This not only guarantees a stable connection of the protective mesh cover but also supports quick disassembly and assembly, enhancing reliability. The sealing rubber ring seals the area where the cleaning brushes are located, preventing dust accumulation and maintaining cleanliness.

[0012] 2. The user aligns the limiting protrusion on the protective mesh cover with the opening of the limiting slot, and then inserts it into the limiting slot. After the limiting protrusion moves to the corner of the limiting slot, rotate the protective mesh cover clockwise to ensure a secure installation. When cleaning the filter screen, the user only needs to rotate the protective mesh cover counterclockwise, and the limiting protrusion will slide along the long side of the limiting slot until it moves to the corner of the limiting slot. Then, pull the protective mesh cover outwards, and the protective mesh cover can be removed.

[0013] 3. When the limiting protrusion moves along the long side of the guide groove, the limiting ball head set on it avoids the movement under the action of the spring until the limiting ball head moves to the ball groove in the limiting slot. The spring immediately rebounds and pushes the limiting ball head into the ball groove to form a lock. When the filter screen needs to be cleaned, the user only needs to rotate the protective screen counterclockwise. When the driving force of the protective screen is greater than the elastic force of the spring, the limiting ball head overcomes the spring resistance and retracts, eventually separating from the ball groove. This ensures the stable connection of the protective screen and supports quick disassembly and assembly, enhancing the reliability of use. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a hair curler, such as Figure 1-5As shown: The device includes a body 100 and several curling comb teeth 200 evenly arranged at its curling end. A fan 101 is installed in the inner cavity of the handle end of the body 100. A heating tube 102, which is an infrared heating tube, is located in the center of the inner cavity of the curling end of the body 100. A filter screen 300 is installed at the air inlet end of the body 100. A protective mesh cover 301 is movably installed at the air inlet end of the body 100. The protective mesh cover 301 has evenly distributed openings on its wall to facilitate air entry. The filter screen 300 is located inside the protective mesh cover 301. The inner arc surface of the protective mesh cover 301 is provided with a plurality of cleaning brushes 302 evenly distributed in a ring. A sealing element is provided between the body 100 and the protective mesh cover 301. A limiting component is also provided between the body 100 and the protective mesh cover 301. The sealing element includes a sealing rubber ring 303 located on the outer arc surface of the body 100 near the filter screen 300. The sealing rubber ring 303 abuts against the inner arc surface of the protective mesh cover 301. The plurality of cleaning brushes 302 are all located in the annular cavity formed by the body 100, the protective mesh cover 301 and the sealing rubber ring 303.

[0018] When the filter 300 needs cleaning, the user simply removes the protective mesh cover 301 using the limiting component, then moves it back and forth while simultaneously rotating it. This allows the cleaning brushes 302, distributed in a ring on the inner arc surface, to clean the filter surface of the filter 300, removing blockages and maintaining its airflow efficiency. By integrating the cleaning brushes 302 with the protective mesh cover 301 and utilizing the synergistic effect of the limiting component and seals, the cleaning function is combined with quick disassembly and assembly, reducing reliance on external tools and significantly improving ease of operation and maintenance efficiency. After cleaning, the user installs the protective mesh cover 301 onto the body 100 using the limiting component, ensuring a secure installation of the protective mesh cover 301. This not only guarantees a stable connection of the protective mesh cover but also supports quick disassembly and assembly, enhancing reliability. The sealing rubber ring 303 seals the area where the cleaning brushes 302 are located, preventing dust accumulation and maintaining cleanliness.

[0019] like Figure 1-2 As shown, the diameter of the body 100 away from the curling end is the same as the diameter of the protective mesh cover 301, ensuring the smoothness of the curling end and the comfort of the user when holding it.

[0020] like Figure 2-3As shown, the limiting component includes a limiting slot 400 disposed on the inner arc surface of the protective mesh cover 301 of the body 100. The inner arc surface of the protective mesh cover 301 is provided with a limiting protrusion 401 that cooperates with the limiting slot 400. The limiting slot 400 is L-shaped. The limiting component also includes a guide groove 402 disposed on the outer arc surface of the limiting protrusion 401. A limiting ball head 403 is slidably connected in the guide groove 402. The limiting ball head 403 is movably inserted into a ball groove corresponding to the inner wall of the limiting slot 400. An elastic element is provided between the limiting ball head 403 and the guide groove 402. The elastic element includes a spring 404 disposed between the outer arc surface of the limiting ball head 403 and the inner wall surface of the guide groove 402.

[0021] The user aligns the limiting protrusion 401 on the protective mesh cover 301 with the opening of the limiting slot 400, and then inserts it into the limiting slot 400. After the limiting protrusion 401 moves to the corner of the limiting slot 400, the user rotates the protective mesh cover 301 clockwise. At this time, the limiting protrusion 401 moves along the long side of the guide groove 402. The limiting ball head 403 on it avoids the movement under the action of the spring 404 until the limiting ball head 403 moves to the ball groove in the limiting slot 400. Then, the spring 404 immediately rebounds and pushes the limiting ball head 403 into the ball groove to form a lock, ensuring the secure installation of the protective mesh cover 301. This design ensures a secure connection for the protective mesh cover while also supporting quick assembly and disassembly, enhancing reliability. When cleaning the filter screen 300, the user simply rotates the protective mesh cover 301 counterclockwise. When the driving force of the protective mesh cover 301 exceeds the elastic force of the spring 404, the limiting ball head 403 overcomes the resistance of the spring 404 and retracts, eventually separating from the ball groove. Then, the user continues to rotate the protective mesh cover 301 counterclockwise. At this point, the limiting protrusion 401 slides along the long side of the limiting slot 400 until it reaches the corner of the limiting slot 400. Then, the user pulls the protective mesh cover 301 outward, and the protective mesh cover 301 can be removed.

[0022] The working principle of the hair curler provided by this utility model is as follows: During normal use, after the fan 101 is started, it generates a directional airflow. The airflow is purified by the filter screen 300 to remove impurities. The filtered clean airflow is then directionally ejected through the precision opening at the curling end of the body 100. The heating tube 102, which operates synchronously, evenly heats the flowing gas to form a constant-temperature controllable hot airflow, which ultimately acts on the user's hair to achieve the styling function. When it is necessary to clean the filter screen 300, the user only needs to rotate the protective mesh cover 301 counterclockwise. When the driving force of the protective mesh cover 301 is greater than the spring... When the spring 404 is released, the limiting ball head 403 overcomes the resistance of the spring 404 and retracts, eventually separating from the ball groove. Then, continue rotating the protective mesh cover 301 counterclockwise. The limiting protrusion 401 slides along the long side of the limiting slot 400 until it reaches the corner of the limiting slot 400. Pull the protective mesh cover 301 outwards, and it can be removed. During this process, the protective mesh cover 301 can be moved back and forth while simultaneously rotating, allowing the cleaning brushes 302 distributed in a ring on its inner arc surface to clean the filter surface of the filter screen 300, removing any blockages. To maintain efficient air circulation, the cleaning brush 302 and protective mesh cover 301 are integrated into one unit. Utilizing the synergistic effect of limiting components and seals, a combination of cleaning function and quick disassembly / removal is achieved, reducing reliance on external tools and significantly improving ease of operation and maintenance efficiency. After cleaning, the user aligns the limiting protrusion 401 on the protective mesh cover 301 with the opening of the limiting slot 400, then inserts it into the limiting slot 400. Once the limiting protrusion 401 has moved to the corner of the limiting slot 400, the protective mesh cover 301 is rotated clockwise. At this point, the limiting protrusion... The column 401 moves along the long side of the guide groove 402. At this time, the limiting ball head 403 set on it avoids the movement under the action of the spring 404. When the limiting ball head 403 moves to the ball groove in the limiting slot 400, the spring 404 immediately rebounds and pushes the limiting ball head 403 into the ball groove to form a snap-fit, ensuring the stable installation of the protective net cover 301. This not only ensures the stable connection of the protective net cover, but also supports quick disassembly and assembly, enhancing the reliability of use. Meanwhile, the sealing rubber ring 303 can seal the area where the cleaning brush 302 is located, preventing dust accumulation and maintaining cleanliness.
