Description

Technical Field

[0001] This utility model relates to the field of cotton swab technology, and in particular to a quick-break cosmetic cotton swab. Background Technology

[0002] Cotton swabs are tools designed specifically for beauty and skincare. They are usually made of absorbent cotton wrapped around a paper or wooden core and are characterized by their softness, cleanliness, and high absorbency. They are mainly used to assist in delicate operations such as makeup application, makeup removal, and skin care.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: In the process of using traditional cotton swabs, the breaking operation mainly relies on manual operation. When users want to obtain cotton swabs of the appropriate length for makeup on specific areas, manual breaking presents many unavoidable problems. Because it is difficult to apply force evenly when manually, the cotton swab stick is easily bent when breaking, which can cause the connection between the cotton head and the stick to loosen, or even cause the cotton head to fall off. Moreover, excessive force may cause the stick to break, producing a sharp break. This not only affects subsequent use but may also cause accidental injury to the user. For example, when used on sensitive areas such as the eyes and lips, the sharp break may scratch the skin. Summary of the Invention

[0004] The technical problem this invention aims to solve is that existing technologies have drawbacks such as uneven force when manually breaking cotton swabs, leading to the swab stem becoming crooked, the cotton head falling off, or the stem breaking. Therefore, we propose a quick-breakable cotton swab.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick-break cotton swab, comprising a cotton swab body and a shell: a handle is fixedly connected to one end of the cotton swab body, the cotton swab body is slidably connected to the inner wall of the shell, a square hole is opened on the arc surface of the shell, a U-shaped frame is fixedly connected to the arc surface of the shell, a threaded rod is threadedly inserted into the U-shaped frame, a blade is rotatably connected to one end of the threaded rod, the blade is slidably connected to the inner wall of the square hole, the blade abuts against the arc surface of the cotton swab body, and a rotating plate is fixedly connected to the end of the threaded rod away from the blade.

[0006] Preferably, a limiting rod is slidably inserted inside the U-shaped frame, and one end of the limiting rod is fixedly connected to the blade.

[0007] Preferably, the arc surface of the rotating plate is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed in a circumferential array on the rotating plate.

[0008] Preferably, a plastic film is fixedly connected to the inner wall of the square hole, and the surface of the plastic film abuts against the blade.

[0009] Preferably, a soft pad is fixedly connected to the arc surface of the handle, and the soft pad is made of silicone.

[0010] Preferably, the cutting edge of the blade is coated with a wear-resistant layer, and the wear-resistant layer is made of high manganese steel.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, the blade is positioned through a square hole on the housing, and the blade is tightly abutted against the arc surface of the cotton swab body. When the rotating plate is rotated, the threaded rod pushes the blade to move along a fixed trajectory. The blade can accurately act on the cotton swab stem of the cotton swab body, cutting the cotton swab stem at a preset position rather than a random position. This avoids the cotton swab stem tilting, cotton head falling off, or stem breaking due to uneven force when breaking the swab manually in the traditional way. It ensures that the two sections of the cotton swab body remain intact after breaking, and the connection between the cotton head and the stem remains firm, without affecting subsequent use.

[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0015] Reference Figures 1-4As shown, this utility model provides a technical solution: a quick-break cotton swab, comprising a cotton swab body 1 and a shell 3; a handle 2 is fixedly connected to one end of the cotton swab body 1; the cotton swab body 1 is slidably connected to the inner wall of the shell 3; a square hole 4 is opened on the arc surface of the shell 3; a U-shaped frame 5 is fixedly connected to the arc surface of the shell 3; a threaded rod 6 is threadedly inserted into the U-shaped frame 5; a blade 7 is rotatably connected to one end of the threaded rod 6; the blade 7 is slidably connected to the inner wall of the square hole 4; the blade 7 abuts against the arc surface of the cotton swab body 1; and the end of the threaded rod 6 away from the blade 7 is fixedly connected to... With the rotating plate 8 connected, the blade 7 is positioned through the square hole 4 on the housing 3, and the blade 7 is tightly abutted against the arc surface of the cotton swab body 1. When the rotating plate 8 is rotated, the threaded rod 6 pushes the blade 7 to move along a fixed trajectory. The blade 7 can accurately act on the cotton swab stem of the cotton swab body 1 and cut the cotton swab stem at a preset position, rather than a random position. This avoids the cotton swab stem tilting, cotton head falling off, or stem breaking caused by uneven force when breaking the cotton swab manually in the traditional way. It ensures that the two sections of the cotton swab body 1 remain intact after being broken, and the connection between the cotton head and the stem remains firm, without affecting subsequent use.

[0016] Reference Figure 3 As shown in this embodiment: a limiting rod 10 is slidably inserted inside the U-shaped frame 5. One end of the limiting rod 10 is fixedly connected to the blade 7. By setting the limiting rod 10, the blade 7 is provided with a guiding function. When the threaded rod 6 is rotated to push the blade 7 closer to or away from the cotton swab body 1, the limiting rod 10 will slide synchronously along the preset trajectory of the U-shaped frame 5 to prevent the blade 7 from shifting or rotating due to uneven force. This stable linear motion trajectory can ensure that the blade 7 is always perpendicularly aligned with the shaft of the cotton swab body 1, so that the cutting force is concentrated on one point.

[0017] Reference Figure 3 As shown in this embodiment: the arc surface of the rotating plate 8 is provided with a number of anti-slip grooves 9. The number of anti-slip grooves 9 are evenly distributed in a circumferential array on the rotating plate 8. By setting the anti-slip grooves 9, the roughness of the surface of the rotating plate 8 can be increased, which significantly improves the friction between the operator's hand and the rotating plate 8, and avoids slipping caused by hand sweat, skin care products or makeup oil.

[0018] Reference Figure 4 As shown in this embodiment: a plastic film 11 is fixedly connected to the inner wall of the square hole 4. The surface of the plastic film 11 abuts against the blade 7. By setting the plastic film 11, the plastic film 11 is tightly attached to the inner wall of the square hole 4, forming a physical barrier to prevent external dust, cosmetic powder or moisture in the air from entering the interior of the housing 3 through the square hole 4, thus avoiding contamination of the cotton swab body 1 or causing the stick to become damp and soft, affecting its performance.

[0019] Reference Figure 1 and Figure 2As shown in this embodiment: a soft pad 12 is fixedly connected to the arc surface of the handle 2. The soft pad 12 is made of silicone. By setting the soft pad 12, the silicone soft pad 12 can increase the friction coefficient between the hand and the handle 2, so that when the user pushes the cotton swab body 1 into and out of the shell 3 or breaks it with the blade 7, the user can stably control the movement direction and force of the handle 2 without deliberately squeezing it.

[0020] Reference Figure 3 As shown in this embodiment, the blade 7 has a wear-resistant layer coated on its cutting edge. The wear-resistant layer is made of high manganese steel. By setting the wear-resistant layer, it can effectively resist the frictional wear during the cutting process of the cotton swab stick. The blade of the traditional blade 7 is prone to rolling and dulling after repeated cutting, which leads to a decrease in cutting force on the cotton swab stick. It may even require frequent replacement of the blade 7 to ensure the breaking efficiency. However, the high manganese steel wear-resistant layer, with its high hardness and excellent wear resistance, can greatly reduce the wear rate of the blade. Even after multiple cutting operations, it can still maintain a sharp state and significantly extend the service life of the blade 7.

[0021] Working principle: In the initial state, the cotton swab body 1 is held by the handle 2 and inserted entirely inside the housing 3. The shaft slides against the inner wall of the housing 3, allowing it to move in and out axially along the housing 3. The plastic film 11 tightly adheres to the inner wall of the square hole 4, forming a physical barrier to prevent dust, cosmetic powder, or moisture from entering the housing 3 through the square hole 4, thus avoiding contamination of the cotton swab body 1 or causing the shaft to soften due to moisture, affecting its effectiveness. When it is necessary to break the cotton swab body 1, the user holds the silicone pad 12 of the handle 2, using the anti-slip and elastic properties of the pad 12 to maintain a stable grip, while the other hand pinches the rotating plate 8. The anti-slip groove 9 increases the friction between the fingers and the rotating plate 8, preventing slippage during rotation. Rotating the rotating plate 8 causes the threaded rod 6 to rotate synchronously. Since the threaded rod 6 is threadedly connected to the U-shaped frame 5, the rotational motion is converted into a linear pushing motion along the axis of the U-shaped frame 5, pushing the blade 7 towards the cotton swab body 1. During the process of the threaded rod 6 pushing the blade 7, the limiting rod 10 inside the U-shaped frame 5 plays a crucial guiding role. The limiting rod 10 slides with the U-shaped frame 5 and is fixedly connected to the blade 7, forcing the blade 7 to move only along the linear trajectory of the square hole 4, preventing the blade 7 from tilting due to the lateral force generated by the rotation of the threaded rod 6. As the blade 7 continues to approach, it cuts through the plastic film and enters the housing 3 through the square hole 4. The high-manganese steel wear-resistant layer on the blade surface first contacts the body of the cotton swab 1. Due to its high hardness and the characteristic of "getting harder with wear," the high-manganese steel material can quickly cut into the body upon contact. During the cutting process, the propulsive force of the blade 7 is concentrated on the cutting edge. Combined with the stable guidance of the limiting rod 10, this ensures that the blade acts perpendicularly to the preset break point of the body, causing the body to break along a flat cross-section, avoiding the skewed or torn breakage that occurs with traditional manual breaking. After the cotton swab body 1 breaks, the rotating plate 8 rotates in the opposite direction, and the threaded rod 6 drives the blade 7 back along its original trajectory. The limiting rod 10 simultaneously resets, and the blade 7... After the cotton swab is broken, the swab stick separates. The user can pull out the broken short section of the cotton swab through the handle 2. In summary, the blade 7 is positioned through the square hole 4 on the housing 3, and the blade 7 is tightly abutted against the arc surface of the cotton swab body 1. When the rotating plate 8 is rotated, the threaded rod 6 pushes the blade 7 to move along a fixed trajectory. The blade 7 can accurately act on the cotton swab stick of the cotton swab body 1 and cut the cotton swab stick at a preset position, rather than a random position. This avoids the cotton swab stick tilting, cotton head falling off, or stick breaking caused by uneven force when breaking the swab manually in the traditional way. It ensures that the two sections of the cotton swab body 1 remain intact after being broken, and the connection between the cotton head and the stick remains firm, without affecting subsequent use.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
