For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] First see Figure 1 and Figure 2The utility model provides a breathable and waterproof shoe cover 10, which can be used to be sleeved on the outside of shoes to achieve waterproof, sand-proof and breathable effects. The breathable and waterproof shoe cover 10 comprises a vamp 100 and a ventilated portion 200, wherein the vamp 100 is enclosed to form a wearing cavity 110, wherein the shoe is placed in the wearing cavity 110 when the shoe is worn, and a window 120 communicating with the wearing cavity 110 is provided on the vamp 100, wherein an edge of the ventilated portion 200 is connected to an edge of the window 120, an inner portion of the ventilated portion 200 bulges outward, and a bulged cavity 210 communicating with the wearing cavity 110 is formed on the inner side of the ventilated portion 200, wherein the gas in the bulged cavity 210 is exchanged with the gas in the wearing cavity 110 through the window 120, and the breathable and waterproof shoe cover 10 is provided with a vent hole 220 on the side of the ventilated portion 200, wherein the vent hole 220 can communicate with the outside, and the gas in the bulged cavity 210 is exchanged with the outside gas through the vent hole 220, thereby better heat dissipation and ventilation are performed, and the stuffiness inside the wearing cavity 110 caused by long-term wearing is prevented.

[0033] refer to Figure 3 In the projection of the breathable and waterproof shoe cover 10 in the vertical direction, the projection of the outer opening of the air hole 220 is covered by the projection of the top of the air permeable part 200. The top of the air permeable part 200 blocks rainwater to prevent rainwater from entering the wearing cavity 110 through the air hole 220. In the direction from the top of the air permeable part 200 to the bottom of the air permeable part 200, the side of the air permeable part 200 gradually sinks toward the center of the air permeable part 200, so that the projection of the outer opening of the air hole 220 does not protrude from the edge of the projection of the top of the air permeable part 200. When rainwater falls into the top surface of the air permeable part 200 in the vertical direction, the rainwater slides to the edge of the top of the air permeable part 200, and then continues to fall under the action of gravity. The rainwater falls outside the projection of the top of the air permeable part 200, thereby preventing rainwater from entering the wearing cavity 110 through the air hole 220 and wetting the shoes.

[0034] Or the projection of the outer opening of the air hole 220 is covered by the projection of the upper 100, and the upper 100 blocks rainwater from entering the wearing cavity 110. The edge of the window 120 on the upper 100 extends toward the center of the raised cavity 210, so that a water retaining surface 121 is formed between the edge of the window 120 and the inner side of the air permeable portion 200. In the projection of the vertical direction of the breathable and waterproof shoe cover 10, the projection of the outer opening of the air hole 220 is within the range of the projection of the water retaining surface 121. In the direction from the top of the air permeable portion 200 to the bottom of the air permeable portion 200, the side of the air permeable portion 200 gradually extends obliquely in the direction away from the center of the air permeable portion 200. At this time, the projection of the outer opening of the air hole 220 is located outside the projection of the top of the air permeable portion 200, and at the same time, the projection of the outer opening of the air hole 220 is located within the projection of the water retaining surface 121. When rain falls into the outer opening of the air hole 220 in the vertical direction, the rain falls onto the water retaining surface 121 through the outer opening of the air hole 220, and the water retaining surface 121 prevents the rain from sliding into the wearing cavity 110. It can be understood that the water retaining surface 121 is inclined, and the water retaining surface 121 extends from the lower edge of the air hole 220 toward the center direction of the raised cavity 210, and in the extension process of the water retaining surface 121, the water retaining surface 121 gradually approaches the upper edge of the air hole 220. It should be noted that the water retaining surface 121 can also be formed in an inclined state under extrusion. For example, the water retaining surface 121 is a deformable material such as plastic or silicone. When the breathable and waterproof shoe cover 10 is sleeved on the shoe, the shoe presses the upper 100 upward, and the end of the water retaining surface 121 away from the edge of the air hole 220 is lifted upward to form the above-mentioned inclined state.

[0035] refer to Figure 3 and Figure 4 The edge contour of the upper 100 is divided into a front edge 130, a rear edge 140, a left edge 150 and a right edge 160. The front edge 130 is opposite to the rear edge 140, and the left edge 150 is opposite to the right edge 160. The upper 100 forms a wearing opening 170 at the rear edge 140. The wearing opening 170 is connected to the wearing cavity 110. When the shoe is worn, it enters the wearing cavity 110 through the wearing opening 170. The breathable portion 200 is located between the wearing opening 170 and the front edge 130. The breathable portion 200 is also located between the left edge 150 and the right edge 160. When walking, the shoe is lifted up and down, so that the breathable portion 200 is squeezed or restored, so that the gas in the bulge cavity 210 enters and exits the bulge cavity 210 through the air hole 220, completing the gas exchange between the bulge cavity 210 and the outside. It can be understood that the breathable portion 200 can also be set at other positions, for example, the breathable portion 200 is set on the side of the upper 100 close to the left edge 150 or close to the right edge 160.

[0036] The outer surface of the upper 100 between the left edge 150 and the right edge 160 is a curved surface 180, and the cross section of the curved surface 180 is a parabola, so that rain or gravel can slide more smoothly. The air permeable portion 200 is arranged along the curved surface 180, and the air permeable portion 200 crosses the vertex of the curved surface 180 in the direction from the left edge 150 to the right edge 160, that is, the air permeable portion 200 spans the center of the left edge 150 and the right edge 160, and the air permeable portion 200 is provided with a side of the left edge 150 and the side of the right edge 160. The air holes 220 are respectively located on the left and right sides of the apex of the arc surface 180, so as to facilitate the gas to enter and exit the raised cavity 210 through the air holes 220 on the left and right sides. In the direction from the front edge 130 to the rear edge 140, the air permeable portion 200 extends from the front edge 130 to the position of the wearing opening 170, so as to maximize the gas exchange space in the raised cavity 210. It can be understood that the so-called parabolic cross-section of the arc surface 180 is similar to a parabolic structure, and the cross-section of the arc surface 180 can be adjusted according to the type of shoes.

[0037] The upper surface of the air permeable portion 200 extends in a curved surface, and the curvature of the curvature of the upper surface of the air permeable portion 200 is the same as the curvature of the corresponding vamp 100, so that the air permeable portion 200 and the vamp 100 are more beautiful. The distance from the vertex of the arc surface 180 of the air permeable portion 200 to the left edge 150 is equal to the distance from the vertex of the arc surface 180 of the air permeable portion 200 to the right edge 160, so that the air holes 220 on the left and right sides of the air permeable portion 200 are relatively positioned, which can better achieve air circulation. When rainwater falls on the upper surface of the air permeable portion 200, the rainwater on the left side of the vertex of the arc surface 180 slides to the left along the upper surface of the air permeable portion 200, and the rainwater on the arc surface The rainwater on the right side of the vertex 180 slides to the right along the upper surface of the breathable portion 200, thereby allowing the rainwater to flow better on the upper surface of the breathable portion 200. It can be understood that the curvature of the upper surface of the breathable portion 200 is different from the curvature of the corresponding shoe upper 100. For example, the curvature of the upper surface of the breathable portion 200 is smaller than the curvature of the corresponding shoe upper 100, and the rainwater can still slide along the upper surface of the breathable portion 200. In this embodiment, the curvature of the upper surface of the breathable portion 200 is the same as the curvature of the corresponding shoe upper 100, which is the best implementation method. As long as it can be ensured that the rainwater slides along the upper surface of the breathable portion 200, no water will form on the upper surface of the breathable portion 200.

[0038] In the orthographic projection from the front edge 130 to the rear edge 140 of the upper 100, the side projection of the vent 200 close to the front edge 130 blocks the projection of the outer opening of the vent 220, so that rainwater does not fall into the vent 220 from the front. In this embodiment, in the orthographic projection from the front edge 130 to the rear edge 140, the projection of the outer opening of the vent 220 is a straight line, that is, the left side or the right side of the vent 200 is perpendicular to the orthographic projection plane, so that the front side of the vent 200 is perpendicular to the front side of the vent The air hole 220 can be blocked. When the user is walking, an inclined state is formed between the rain and the upper 100. The rain moves obliquely from the front side to the rear side of the air permeable portion 200 during the falling process. At this time, the front side surface of the air permeable portion 200 can block the rain from falling into the air hole 220 from the front side to the rear side of the air permeable portion 200. It can be understood that in other embodiments, the outer opening of the air hole 220 may not be a straight line, as long as the projection of the front side of the air permeable portion 200 blocks the projection of the outer opening of the air hole 220.

[0039] refer to Figure 5 The air holes 220 extend in strips, and the air holes 220 extend from the side where the rear edge 140 is located to the side where the front edge 130 is located. In the present embodiment, the air holes 220 extend from the front end of the air permeable portion 200 to the rear end of the air permeable portion 200 along the left and right sides of the air permeable portion 200, and the air holes 220 extend in the direction from the bottom side to the top side of the air permeable portion 200, thereby increasing the gas exchange efficiency of the air holes 220. It should be noted that the air holes 220 may also be circular holes or triangular holes, and a plurality of air holes 220 are arranged at intervals, which can also achieve a good ventilation effect.

[0040] A partition bar 221 is arranged in the strip-shaped air hole 220, and the partition bar 221 divides the strip-shaped air hole 220 into a plurality of small sub-air holes. One end of the partition bar 221 is connected to the upper hole wall of the air hole 220, and the other end is connected to the lower hole wall of the air hole 220. A plurality of partition bars 221 are arranged, and the plurality of partition bars 221 are arranged at intervals along the two ends of the extending direction of the air hole 220, and the interval distance between each partition bar 221 is the same, so that the size of each sub-air hole is the same and more coordinated, and the partition bars 221 are arranged at the same distance. The strips 221 are arranged between the upper hole wall and the lower hole wall of the air hole 220 so that the partition strips 221 support the top of the air permeable part 200 to prevent the top of the air permeable part 200 from collapsing due to external force. It should be noted that the number of the partition strips 221 in the air hole 220 on the left side of the air permeable part 200 is the same as that of the partition strips 221 in the air hole 220 on the right side, and the partition strips 221 on both sides are opposite in position so that the partition strips 221 are evenly stressed and the symmetrical arrangement makes the air permeable part 200 more beautiful.

[0041] The air hole 220 is provided in the outwardly raised portion of the air permeable portion 200, i.e., the side of the raised portion of the air permeable portion 200. The outer opening of the air hole 220 is higher than the vertically opposite upper 100. In the present embodiment, the lower hole wall of the air hole 220 is higher than the vertically opposite surface of the upper 100, so that rainwater will not flow back from the surface of the upper 100 into the air hole 220, thereby improving the waterproof performance.

[0042] refer to Figure 1 The upper 100 is also provided with a ventilation opening 190, which connects the wearing cavity 110 with the outside world. The ventilation opening 190 is used for gas exchange between the wearing cavity 110 and the outside world, thereby increasing the ventilation effect of the breathable and waterproof shoe cover 10. The ventilation opening 190 is in a hole-shaped form, and a plurality of ventilation openings 190 are provided. In the present embodiment, the ventilation opening 190 is provided at one end of the left edge 150 of the upper 100 close to the front edge 130, and at one end of the right edge 160 close to the front opening. It can be understood that the ventilation opening 190 can also be provided at other positions of the upper 100, for example, the ventilation opening 190 can also be provided on the front side of the upper 100. Multiple ventilation openings 190 can allow air to circulate, thereby increasing the ventilation effect of the front end of the shoe.

[0043] The air permeable portion 200 and the upper 100 are integrally formed by injection molding, and the air permeable and waterproof shoe cover 10 is a flexible rubber cover, so that the air permeable and waterproof shoe cover 10 has a good deformation effect while ensuring waterproofness. The flexible rubber cover can be a deformable plastic, or latex, silicone, etc.

[0044] refer to Figure 1 and Figure 2The breathable and waterproof shoe cover 10 also includes a sole 300 connected to the upper 100, and the sole 300 includes a first bottom sheet 310 and a second bottom sheet 320 arranged at intervals. The first bottom sheet 310 is respectively connected to the front edge 130, the left edge 150 and the right edge 160, and the second bottom sheet 320 is respectively connected to the left edge 150 and the right edge 160. The second bottom sheet 320 is arranged in the middle position from the front edge 130 to the rear edge 140. The first bottom sheet 310 and the second bottom sheet 320 are relatively spaced apart, so that the wearing cavity 110 can also exchange gas with the outside through the interval opening between the first bottom sheet 310 and the second bottom sheet 320, thereby providing The highly breathable and waterproof shoe cover 10 has a breathable effect. When the shoe is worn into the wearing cavity 110, the first bottom film 310 and the second bottom film 320 prevent the shoe from escaping from the bottom of the wearing cavity 110. The first bottom film 310, the second bottom film 320 and the upper 100 are an injection-molded integral structure. According to the force points of the human foot when walking and the walking habits of most people, the rear end of the shoe is subjected to the greatest force and the most serious wear. The first bottom film 310 and the second bottom film 320 are respectively arranged at the front and the middle, thereby minimizing the friction between the breathable and waterproof shoe cover 10 and the ground when walking, and extending the service life of the breathable and waterproof shoe cover 10.

[0045] refer to Figure 3 The breathable and waterproof shoe cover 10 also includes a fixing belt 400, and the wearing opening 170 is formed by enclosing the fixing belt 400. The fixing belt 400 and the upper 100 are integrally formed by injection molding. The fixing belt 400 includes a first belt body 410 and a second belt body 420. One end of the first belt body 410 is connected to the left edge 150 of the upper 100, and the other end is provided with a first connecting member 430. One end of the second belt body 420 is connected to the right edge 160 of the upper 100, and the other end is provided with a second connecting member 440. The first connecting member 430 can be connected and fixed with the second connecting member 440 at different positions, so that the size of the wearing opening 170 can be adjusted, thereby adjusting the wearing tightness of the breathable and waterproof shoe cover 10. It should be noted that the first connecting member 430 and the second connecting member 440 can be the hook surface and the wool surface of Velcro, or two magnetic patches that are magnetically attracted to each other.
