AI Technical Summary
灰尘颗粒(尤其是细小的泥土、沙尘)进入后，容易被四周的弧形凸起壁阻挡，且由于各方向均有遮挡，很难通过自然震动(如篮球运球时的颠簸)或气流自行排出，最终在间隙内堆积，既会更易弄脏篮球等的表面，又会破坏原有密集圆形凸起的构造，降低摩擦力
[0015]本申请提供的防尘皮革上设置有条状凸起，相邻长条状凸起之间的间隙呈“开放沟槽状”。长条结构沿某一方向延伸，间隙是连续的线性通道，而非封闭空间。灰尘进入后，不会被多方向的凸起壁“困住”，反而更容易在篮球运动(如滚动、抛接)时，被惯性力或接触面(手掌、地面)的摩擦“推挤”出沟槽，减少滞留。沿固定方向延伸的结构(如条状结构)会引导气流沿长条方向流动，形成更稳定的“线性气流”。这种气流能顺着沟槽方向持续冲刷，像“扫帚”一样将间隙内的灰尘顺着长条延伸方向带走，减少灰尘在局部的沉积。同时，在清洁时，线性沟槽无明显拐角，擦拭工具(如毛巾)可沿长条方向直接划过整个沟槽，轻松清除残留灰尘，减少清洁盲区。

Description
Technical Field
[0001] This application relates to the field of daily necessities, specifically to a type of dustproof leather. Background Technology
[0002] As people's living standards improve, more and more people are participating in sports and exercise, and the variety of sports and exercise programs has also increased. These range from ball sports like basketball, volleyball, handball, and water polo, which only involve playing with balls, to sports requiring rackets like badminton, tennis, baseball, and table tennis, and even sports equipment like stationary bikes and fitness equipment. All of these sports require direct contact between the user's hands and the ball, racket, or equipment, and a considerable degree of friction is needed to help us better control the ball, grip the racket, and hold the equipment more firmly, especially in competitions or professional arenas where even more reliable friction is required. Some existing technologies and market solutions involve adding tiny circular protrusions to the surface of the particles, with the gaps between adjacent protrusions forming a "closed pocket" shape. The circular curved surfaces surround the gaps from multiple directions, creating a space similar to a "pit." When dust particles (especially fine dirt and sand) enter, they are easily blocked by the surrounding curved raised walls. Because they are blocked from all directions, they are difficult to expel by natural vibration (such as the bumps when dribbling a basketball) or airflow. They eventually accumulate in the gaps, which not only makes the surface of the basketball dirtier, but also damages the original dense circular raised structure and reduces friction. Utility Model Content
[0003] To solve the above-mentioned technical problems, this application provides a type of leather with dust-proof effect, the specific technical solution of which is as follows:
[0004] A dustproof leather, characterized in that it comprises: a leather base surface; and a plurality of anti-slip particle units vertically disposed on the leather base surface; each of the anti-slip particle units is composed of a base and protrusions; the protrusions include circular protrusions and strip protrusions, both of which are vertically disposed on the base surface.
[0005] In one specific embodiment of this application, the base of the anti-slip particle unit is a cylinder.
[0006] In one specific embodiment of this application, the plane of the substrate away from the leather base surface is regarded as the upper surface of the substrate, and the circular protrusions and strip protrusions are alternately and vertically arranged at the outer edge of the upper surface of the substrate.
[0007] In one specific embodiment of this application, a central protrusion is provided at the center of the plane of the substrate away from the leather base surface. The central protrusion is circular in shape, and one end of the plurality of strip-shaped protrusions faces the central protrusion.
[0008] In one specific embodiment of this application, the number of circular protrusions is 4 to 6, the number of strip-shaped protrusions is 4 to 6, and the number of circular protrusions and strip-shaped protrusions is consistent.
[0009] In one specific embodiment of this application, the spacing between adjacent anti-slip particle units on the leather base surface is 0.2 to 0.8 mm.
[0010] In one specific embodiment of this application, the base height H of the anti-slip particle unit is 0.4 to 0.8 mm, and the diameter D of the upper surface of the base is 2 to 3 mm.
[0011] In one specific embodiment of this application, the height h2 of the circular protrusion is 0.1 to 0.4 mm, and the diameter d1 of the upper surface of the circular protrusion is 0.1 to 0.5 mm.
[0012] In one specific embodiment of this application, the height h1 of the strip-shaped protrusion is 0.1 to 0.4 mm, the width W of the strip-shaped protrusion is 0.1 to 0.5 mm, and the length L of the strip-shaped protrusion is 0.5 to 1 mm.
[0013] In one specific embodiment of this application, the height h3 of the central protrusion is 0.2 to 0.5 mm, and the diameter d of the upper surface of the central protrusion is 0.4 to 0.8 mm.
[0014] This application has the following beneficial technical effects:
[0015] The dustproof leather provided in this application features strip-shaped protrusions, with the gaps between adjacent strip-shaped protrusions forming "open grooves." The strip structures extend in a single direction, and the gaps are continuous linear channels, not closed spaces. Dust entering is not "trapped" by the multi-directional protrusion walls; instead, it is more easily "pushed" out of the grooves by inertia or friction from the contact surface (palm, ground) during basketball movements (such as rolling and catching), reducing retention. Structures extending in a fixed direction (such as strip structures) guide airflow along the strip direction, forming a more stable "linear airflow." This airflow continuously washes along the groove direction, like a "broom," carrying away dust from the gaps along the strip's extension direction, reducing localized dust accumulation. Simultaneously, during cleaning, the linear grooves have no obvious corners, allowing wiping tools (such as towels) to directly glide across the entire groove along the strip direction, easily removing residual dust and reducing cleaning blind spots.

[0046] In this application, the description of the shape of the protrusion (such as "circular" or "strip") should be understood as the shape of the protrusion as observed when the line of sight is perpendicular to the upper surface of the anti-slip particle unit; furthermore, when the viewing angle is changed, the three-dimensional structure displayed by the circular protrusion can be a cylinder; the same applies to the strip protrusion. Therefore, it should be understood that the descriptions such as "circular" and "strip" are for the purpose of more intuitively and accurately describing the structural features of the product, and are not intended to confuse planar or three-dimensional geometric figures.
[0047] The dustproof leather provided in this application will be described in detail in the embodiments below. It should be understood that all descriptions of the shape, structure and features of the anti-slip particle unit do not specifically refer to the process of the structure or the method of assembly and fixing, but are merely a simplified description of the complex shape of the anti-slip particle unit in a way that is easy to understand.
[0048] Example
[0049] This embodiment provides a dustproof leather, which includes: a leather base surface; and a plurality of anti-slip particle units vertically disposed on the leather base surface; and a plurality of such anti-slip particle units are disposed on the leather base surface. Figure 1 The illustrated anti-slip particle unit includes a base and protrusions vertically disposed on the base. The base is circular, with a height H = 0.4 mm and a diameter D = 2 mm on its upper surface. The protrusions include circular protrusions and strip-shaped protrusions. The strip-shaped protrusions have a height h1 = 0.1 mm, a length L = 0.5 mm, and a width W = 0.1 mm. The circular protrusions have a height h2 = 0.1 mm and a diameter d1 = 0.1 mm on their upper surfaces. The side of the circular base away from the leather substrate is considered the upper surface of the circular base. The circular and strip-shaped protrusions are alternately and vertically disposed along the edge of the upper surface of the circular base in a pattern of "one circular protrusion, one strip-shaped protrusion," until six circular protrusions and six strip-shaped protrusions are disposed on the base. A central protrusion is also provided at the center of the upper surface of the circular base. The central protrusion is circular, with a height of h3 = 0.2 mm and a diameter of d2 = 0.4 mm on the upper surface of the central protrusion. One end of each of the strip-shaped protrusions faces the central protrusion.
[0050] The following is combined with Figure 3The illustrated three-dimensional diagram details the dustproof leather provided in Embodiment 1. In addition to the circular protrusions, the anti-slip particle units on the dustproof leather also have strip-shaped protrusions. The open grooves and continuous linear channels formed by the strip-shaped protrusions avoid the closed or multi-directional surrounding spaces that the circular protrusions might create. Dust entering is not "trapped" by the complex protruding walls and is more easily pushed out by inertial forces, hand or bottom friction during use (such as when the dustproof leather is used for balls, during throwing, catching, or dribbling), thus reducing the chance of dust "settling" in the gaps. In contrast, the gaps between circular protrusions may cause dust to get stuck or accumulate due to the curvature or multi-directional obstruction, making it difficult to remove by natural forces during movement.
[0051] The strip-shaped structure extending along a fixed direction can directionally guide airflow, forming a stable and continuous linear airflow. This airflow continuously washes away the crevices along the groove direction, actively carrying away the deposited dust and achieving dynamic "self-cleaning." In contrast, the airflow around the circular protrusions tends to form turbulent eddies, which not only fail to effectively remove dust but may also engulf external dust into the depths of the crevices. Furthermore, the stability of the linear airflow can also, to some extent, prevent external floating dust from easily falling into or remaining in the grooves.
[0052] Furthermore, in basketball scenarios, the extension direction of the strip-shaped protrusions can be adapted to the common trajectories of ball rolling and hand grip. For example, when the basketball rolls, the groove direction is consistent with the direction of movement, which can reduce the possibility of dust getting stuck due to "reverse direction jamming"; when gripping, the friction distribution of the linear structure is more uniform, which not only ensures grip stability, but also allows dust in the groove to be expelled smoothly through the pushing and pulling of hand movements. On the other hand, the irregular gaps of the circular protrusions may "counteract" external forces during movement, which may actually exacerbate dust embedding.
[0053] Because dust does not easily accumulate, the raised stripes on the leather surface help maintain a clean appearance for a longer period, reducing the "dirty" look caused by dust buildup. At the same time, fine particles in dust, if left unattended for a long time, can cause wear and tear on the leather surface during friction; the dust-resistant properties of the striped structure indirectly reduce this risk of wear, helping to extend the leather's lifespan and performance stability.
[0054] Although the embodiments of this application have been described above in conjunction with the accompanying drawings, this application is not limited to the specific embodiments and application fields described above. The specific embodiments described above are merely illustrative and instructive, not restrictive. Those skilled in the art can make many other forms based on the guidance of this specification and without departing from the scope of protection of the claims of this application, and these are all within the scope of protection of this application.
