[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-6 This utility model provides a technical solution, including the following embodiments:

[0028] Example 1

[0029] Combination Figure 1 , Figure 2 and Figure 3 This embodiment provides the overall structure of an anti-fouling foot pad. The main pad 1 is made of rubber, which is elastic and wear-resistant. Its top is provided with a linear array of raised groups, with a predetermined spacing between each pair of raised groups, separated by grooves 12, specifically 10mm-30mm apart. The grooves 12 have smooth surfaces, facilitating dirt collection and cleaning. The bottom four corners of the main pad 1 are provided with receiving grooves 13, in which suction cups 2 are fixedly installed to stably fix the foot pad to the ground; the top four corners are provided with raised portions 11 to enhance anti-slip properties and aesthetics. Simultaneously, corresponding to the positions of the receiving grooves (13), the thickness of the main pad 1 in that area is increased to prevent the area from being too thin due to the presence of the receiving grooves (13). When a user steps on it, the sole of the shoe contacts the raised groups, removing dirt through a scraping action. The dirt falls into the grooves 12 and can be quickly removed by shaking the main pad 1. Figure 1 A top view of motherboard pad 1 is shown, revealing the linear array distribution of the bumps and the location of grooves 12. Figure 3 The cross-sectional view shows the height differences of the protrusion group and the depth structure of the gully 12, highlighting the overall layout.

[0030] Example 2

[0031] Combination Figure 4 and Figure 5 This embodiment focuses on describing the structure and function of the scratching assembly.

[0032] Specifically, each protrusion group includes two scraping groups, each consisting of a linearly arranged first flexible protrusion 3, a second flexible protrusion 31, a third flexible protrusion 32, and a fourth flexible protrusion 33. These protrusions are distributed sequentially from high to low with equal spacing. This gradient distribution allows the scraping group to function similarly to a shoe brush: when the sole is scraped, the higher-positioned first flexible protrusion 3 first contacts the sole, gradually transitioning to the lower-positioned fourth flexible protrusion 33, scraping away dirt from the sole through the elastic deformation of the flexible protrusions. During the scraping process, the dirt is guided to the grooves 12, achieving efficient cleaning. Figure 4 The partial cross-sectional view shows the arrangement of the protrusions inside the scraping assembly and their connection with the groove 12. Figure 5 The enlarged image more clearly shows the gradient changes of the convex pillars of the scraping group, highlighting its brush-like design.

[0033] Example 3

[0034] Combination Figure 6 As shown, this embodiment details the working principle of the pedal assembly.

[0035] Specifically, each set of raised sections is located between two scraping sections, comprising two sets of short, flexible raised pillars 41 and two sets of high, flexible raised pillars 4. The high, flexible raised pillars 4 are symmetrically arranged on opposite sides of the short, flexible raised pillars 41, and are located on one side of the groove 12. This structure, with a lower center (short raised pillars) and higher sides (high raised pillars), ensures that the high, flexible raised pillars 4 contact the sole first when stepped on. Due to the flexibility of the rubber material, the high, flexible raised pillars 4 deform and slide on the sole surface, producing a scraping effect: the deformed high raised pillars scoop up dirt from the sole and push it towards the central area of ​​the short raised pillars, where the dirt eventually falls into the groove 12. This design enhances dirt removal efficiency, especially suitable for sticky dirt. Figure 6 The enlarged view shows the arrangement of the high-flexibility protrusion 4 and the low-flexibility protrusion 41 in the trampling group, as well as their cooperative relationship with the groove 12.

[0036] Example 4

[0037] Combination Figure 1 and Figure 4 As shown in the figure, this embodiment illustrates the advantage of the two scraping groups in the protrusion group facing opposite directions.

[0038] Specifically, the two scraping groups in each raised group face opposite directions, meaning that when the user enters or leaves the footpad, the sole of the shoe can contact the higher part of the scraping group (such as the first flexible protrusion 3). A drop space is formed between the higher part and the groove 12, similar to a cone surface, facilitating the flow of dirt into the groove 12 during the scraping process. During entry and exit, the sole of the shoe contacts the scraping groups facing different directions successively, and dirt is scraped multiple times and collected in the groove 12 through the drop space, preventing dirt from accumulating on the raised groups. This design ensures anti-fouling effect during bidirectional use and improves practicality. Through the above embodiments, the anti-fouling footpad achieves efficient dirt removal and easy cleaning, extending its service life. This utility model is not limited to the above embodiments; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the tops of the first flexible protrusion 3, the second flexible protrusion 31, the third flexible protrusion 32, the fourth flexible protrusion 33, the highly flexible protrusion 4, and the lowly flexible protrusion 41 are smooth spherical surfaces. Because there are uniform gaps between these protrusions, when the sole of the shoe or foot is dirty, the actual contact area is significantly reduced because the contact point is only the smooth tops of these tiny protrusions, making it difficult for dirt to adhere firmly. Most of the dust and mud will fall directly into the gaps without forming stains on the surface. When lifting the foot or cleaning, the rebound effect of the elastic protrusions and their smooth tops easily bounce off most of the dirt or allow it to sink to the bottom of the gaps, thus keeping the surface clean. Cleaning only requires a simple patting or rinsing to remove accumulated dirt from the gaps, achieving a physical "non-stick" effect.

[0039] Working principle: The scraping assembly consists of a linear array of four flexible protrusions—a first flexible protrusion 3, a second flexible protrusion 31, a third flexible protrusion 32, and a fourth flexible protrusion 33—arranged in descending order of height to form a gradient scraping structure with a shoe brush effect. High-flexibility protrusions 4 are located on one side of the groove 12, forming a structure that is low in the middle and high on both sides. This allows the high-flexibility protrusions 4 to contact the sole first and deform during stepping, producing a sliding scraping effect. A drop space is formed between the highest flexible protrusion 3 in the scraping assembly and the groove 12, ensuring that the sole is subjected to scraping when entering or exiting the insole. The scraping of the high part of the scraping group guides and collects the dirt into the groove 12; the tops of the first flexible protrusion 3, the second flexible protrusion 31, the third flexible protrusion 32, the fourth flexible protrusion 33, the high flexible protrusion 4 and the low flexible protrusion 41 are smooth spherical surfaces, and there are uniform gaps between each protrusion, which greatly reduces the actual contact area with dirt. The elastic rebound makes the dirt fall into the gap, achieving a physical non-stick effect; the bottom four corners of the main board pad 1 are provided with receiving grooves 13, in which suction cups 2 are fixed, and the top four corners are provided with protrusions 11 to enhance the fixing and anti-slip performance.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
