Description

Technical Field

[0001] The present invention relates to the technical field of footwear, and in particular, to a shoe upper and a breathable shoe. Background Art

[0002] Most of the breathable shoes on the market now use breathable soles or shoe uppers so that the air inside the shoes can circulate and exchange with the outside air, thereby achieving the effect of breathability. However, none of these breathable shoes can achieve air replacement. For example, when ventilation holes are provided in the shoe upper or sole, when the foot steps down, the stench inside the shoe is discharged, and when the foot is lifted, the stench just discharged around the shoe will be sucked back, and it will not flow directionally. Therefore, the existing breathable shoes have a certain breathable effect, but the breathable effect is not significant, and the anti-odor effect is poor. Summary of the Invention

[0003] In view of this, the embodiments of the present disclosure provide a shoe upper and a breathable shoe, which at least partially solve the problems existing in the prior art.

[0004] The embodiments of the present disclosure provide a shoe upper for connecting with a sole. The shoe upper and the sole enclose to form a shoe cavity. The shoe upper includes a first side surface and a second side surface oppositely arranged along a first direction, and a first tapered hole and a second tapered hole communicating the shoe cavity with the outside. Among them, the first tapered hole is provided on the first side surface, the second tapered hole is provided on the second side surface, the large-diameter end of the first tapered hole and the small-diameter end of the second tapered hole are respectively communicated with the shoe cavity, and the small-diameter end of the first tapered hole and the large-diameter end of the second tapered hole are respectively communicated with the outside.

[0005] According to a specific implementation manner of the embodiments of the present disclosure, the number of the first tapered holes is equal to the number of the second tapered holes.

[0006] According to a specific implementation manner of the embodiments of the present disclosure, the shoe upper includes a lining, an interlayer, a surface layer and a tapered hole film arranged in a stacked manner. The lining and the sole enclose to form a shoe cavity. The interlayer is arranged on the surface of the lining facing away from the shoe cavity. The surface layer is arranged on the side of the interlayer facing away from the interlayer. The first tapered hole and the second tapered hole are arranged on the tapered hole film. Among them, the tapered hole film is arranged on the surface of at least one of the surface layer, the lining and the interlayer.

[0007] According to a specific implementation manner of the embodiments of the present disclosure, the surface layer, the lining and the interlayer are made of breathable materials.

[0008] According to a specific implementation manner of the embodiments of the present disclosure, the shoe upper further includes a third side surface and a fourth side surface oppositely arranged along a second direction. The first tapered hole is further provided on the third side surface, the second tapered hole is further provided on the fourth side surface, and the first direction and the second direction intersect.

[0009] According to a specific implementation manner of an embodiment of the present disclosure, the shoe upper further includes a top surface, which is disposed opposite to the sole in a third direction and is connected to the first side surface, the second side surface, the third side surface, and the fourth side surface. Ventilation holes communicating the shoe cavity with the outside are provided on the top surface, and the first direction, the second direction, and the third direction intersect pairwise.

[0010] According to a specific implementation manner of an embodiment of the present disclosure, the taper angles of the first tapered hole and the second tapered hole are equal.

[0011] According to a specific implementation manner of an embodiment of the present disclosure, the taper angles of the first tapered hole and the second tapered hole are α, where 0 < α ≤ 23° or 30° < α ≤ 120°.

[0012] The second aspect of the present disclosure provides a breathable shoe, including a sole and a shoe upper as described in any one of the foregoing first aspects, and the shoe upper is connected to the sole.

[0013] The shoe upper in the embodiment of the present disclosure includes a first side surface and a second side surface disposed opposite to each other in a first direction, and a first tapered hole and a second tapered hole communicating the shoe cavity with the outside. Among them, the first tapered hole is provided on the first side surface, the second tapered hole is provided on the second side surface, the large-diameter end of the first tapered hole and the small-diameter end of the second tapered hole are respectively communicated with the shoe cavity, and the small-diameter end of the first tapered hole and the large-diameter end of the second tapered hole are respectively communicated with the outside. Since the resistance of the gas flowing in the tapered hole from the small-diameter end to the large-diameter end is different from that from the large-diameter end to the small-diameter end, and the first tapered hole and the second tapered hole face the same direction, the first tapered hole, the second tapered hole, and the shoe cavity form a valve-less pump structure. When a person walks, the movement of the foot in the shoe cavity changes the air pressure in the shoe cavity, so that one of the first side surface and the second side surface has more air intake and less air outlet, and the other has less air intake and more air outlet, forming a directional flow of the gas between the shoe cavity and the outside macroscopically, realizing the ventilation between the shoe cavity and the outside, and improving the breathability and anti-odor effect.

[0023] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0024] Most of the breathable shoes on the market now use breathable soles or uppers so that the air inside the shoes can circulate and exchange with the outside air, thus achieving the effect of breathability. However, none of these breathable shoes can achieve air exchange. For example, when ventilation holes are provided on the upper or the sole, when the foot steps down, the stinky air inside the shoes is discharged, and when the foot is lifted, the stinky air just discharged around the shoes will be sucked back, and there will be no directional flow. Therefore, the existing breathable shoes have a certain breathable effect, but the breathable effect is not significant, and the anti-odor effect is poor.

[0025] To solve the above problems, the embodiments of the present disclosure provide an upper and a breathable shoe. The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 2 , an upper 10 disclosed in an embodiment of the first aspect of the present disclosure is used to be connected to a sole. The upper 10 and the sole enclose a shoe cavity. The upper 10 includes a first side 1 and a second side 2 oppositely arranged along a first direction X, and a first tapered hole 3 and a second tapered hole 4 that communicate the shoe cavity with the outside. Among them, the first tapered hole 3 is provided on the first side 1, the second tapered hole 4 is provided on the second side 2, the large-diameter end of the first tapered hole 3 and the small-diameter end of the second tapered hole 4 are respectively communicated with the shoe cavity, and the small-diameter end of the first tapered hole 3 and the large-diameter end of the second tapered hole 4 are respectively communicated with the outside.

[0027] In the upper 10 of the embodiments of the present disclosure, the first tapered hole 3 and the second tapered hole 4 are respectively provided on the first side 1 and the second side 2. Since the resistance of the gas flowing in the tapered hole is different when flowing from the small-diameter end to the large-diameter end and from the large-diameter end to the small-diameter end, and the first tapered hole 3 and the second tapered hole 4 face the same direction, the first tapered hole 3, the second tapered hole 4 and the shoe cavity form a valve-less pump structure. When a person walks, the movement of the foot in the shoe cavity changes the air pressure in the shoe cavity, so that one of the first side 1 and the second side 2 has more air intake and less air outlet, and the other has less air intake and more air outlet, forming a directional flow of the gas between the shoe cavity and the outside in macro, realizing the air exchange between the shoe cavity and the outside, and improving the breathability and anti-odor effect.

[0028] Regarding the shapes of the first tapered hole and the second tapered hole, the first tapered hole and the second tapered hole may be the same or different. Preferably, the first tapered hole and the second tapered hole have the same shape. Exemplarily, the shapes of the first tapered hole and the second tapered hole are both square tapered holes, that is, the large-diameter ends and the small-diameter ends of the first tapered hole and the second tapered hole are both polygons, and the inner wall surfaces of the first tapered hole and the second tapered hole are multiple planes, and the multiple planes are connected end to end in sequence.

[0029] Of course, the inner wall surfaces of the first tapered hole and the second tapered hole may also be curved surfaces, and the curved surfaces may be curved once or multiple times. For example, the curved surface may be an S-shaped curved surface. At this time, the large-diameter ends and the small-diameter ends of the first tapered hole and the second tapered hole may be circular, elliptical or polygonal.

[0030] In some alternative embodiments, both the first tapered hole and the second tapered hole are conical holes. Specifically, depending on the different taper angles of the first tapered hole 3 and the second tapered hole 4, the resistance of the gas flowing from the small-diameter end to the large-diameter end is greater than the resistance of the gas flowing from the large-diameter end to the small-diameter end, or the resistance of the gas flowing from the small-diameter end to the large-diameter end is less than the resistance of the gas flowing from the large-diameter end to the small-diameter end. To ensure that one of the first side 1 and the second side 2 has more air intake and less air outlet, and the other has less air intake and more air outlet, forming a directional flow of gas between the shoe cavity and the outside in a macroscopic sense, the taper angles of the first tapered hole 3 and the second tapered hole 4 should be as close as possible. Preferably, the taper angles of the first tapered hole 3 and the second tapered hole 4 are equal.

[0031] Exemplarily, the taper angles of both the first tapered hole 3 and the second tapered hole 4 are α, where 0 < α ≤ 23° or 30° < α ≤ 120°.

[0032] When 0 < α ≤ 23°, when a person is walking, the activity of the foot in the shoe cavity causes the air pressure in the shoe cavity to increase or decrease. When the air pressure in the shoe cavity increases, the gas in the shoe cavity will flow from the first tapered hole 3 and the second tapered hole 4 to the outside. At this time, the resistance of the gas flowing out from the first tapered hole 3 is greater than the resistance of the gas flowing out from the second tapered hole 4. Therefore, the gas flow rate flowing out from the second tapered hole 4 is greater than the gas flow rate flowing out from the first tapered hole 3. When the air pressure in the shoe cavity decreases, the outside gas will flow from the first tapered hole 3 and the second tapered hole 4 into the shoe cavity. At this time, the resistance of the gas flowing into the first tapered hole 3 is less than the resistance of the gas flowing into the second tapered hole 4. Therefore, the gas flow rate flowing into the first tapered hole 3 is greater than the gas flow rate flowing into the second tapered hole 4. As the air pressure in the shoe cavity repeatedly increases and decreases, after the total flow rates are offset, the gas flow direction is along the direction of outside, the first side 1, the shoe cavity, the second side 2, and outside, thereby realizing the air exchange between the shoe cavity and the outside, improving the air permeability and the anti-odor effect.

[0033] When 30° < α ≤ 120°, when the air pressure in the shoe cavity increases, the gas in the shoe cavity will flow from the first tapered hole 3 and the second tapered hole 4 to the outside. At this time, the resistance of the gas flowing out from the second tapered hole 4 is greater than the resistance of the gas flowing out from the first tapered hole 3. Therefore, the gas flow rate flowing out from the first tapered hole 3 is greater than the gas flow rate flowing out from the second tapered hole 4. When the air pressure in the shoe cavity decreases, the outside gas will flow from the second tapered hole 4 and the first tapered hole 3 into the shoe cavity. At this time, the resistance of the gas flowing into the second tapered hole 4 is less than the resistance of the gas flowing into the first tapered hole 3. Therefore, the gas flow rate flowing into the second tapered hole 4 is greater than the gas flow rate flowing into the first tapered hole 3. As the air pressure in the shoe cavity repeatedly increases and decreases, after the total flow rates are offset, the gas flow direction is along the direction of outside, the second side 2, the shoe cavity, the first side 1, and outside, thereby realizing the air exchange between the shoe cavity and the outside, improving the air permeability and the anti-odor effect.

[0034] In some alternative embodiments, the number of the first tapered holes 3 is equal to the number of the second tapered holes 4. To ensure that there is a difference in the gas flow rates flowing out of or into the first side surface 1 and the second side surface 2, so as to achieve a macroscopic air flow in a fixed direction, the number of the first tapered holes 3 and the number of the second tapered holes 4 should be as close as possible. Preferably, the number of the first tapered holes 3 is equal to the number of the second tapered holes 4, to prevent the gas flow rates flowing out of or into the first side surface 1 and the second side surface 2 from being close due to the difference in the number of the first tapered holes 3 and the second tapered holes 4, resulting in poor ventilation effect.

[0035] In some alternative embodiments, the shoe upper 10 includes a lining, an interlayer, a surface layer, and a tapered hole film arranged in a stacked manner. The lining and the sole enclose to form a shoe cavity. The interlayer is arranged on the surface of the lining facing away from the shoe cavity. The surface layer is arranged on the side of the interlayer facing away from the interlayer. The first tapered holes 3 and the second tapered holes 4 are arranged in the tapered hole film. Among them, the tapered hole film is arranged on the surface of at least one of the surface layer, the lining, and the interlayer.

[0036] In these alternative embodiments, both the first tapered holes 3 and the second tapered holes 4 are arranged on the tapered hole film. Optionally, the first tapered holes 3 and the second tapered holes 4 can be obtained by means such as track etching and laser processing on the film layer. The tapered hole film is attached to the surface of at least one of the lining, the interlayer, and the surface layer. The lining, the interlayer, and the surface layer do not need to be provided with the first tapered holes 3 and the second tapered holes 4, which can reduce the processing difficulty of the shoe upper 10.

[0037] In some alternative embodiments, the surface layer, the lining, and the interlayer are made of breathable materials. Exemplarily, the breathable materials can include one or more of fine canvas, cotton cloth, breathable leather, and sponge. In these alternative embodiments, making the surface layer, the lining, and the interlayer of breathable materials can further improve the ventilation effect.

[0038] In some alternative embodiments, the shoe upper 10 further includes a third side surface 5 and a fourth side surface 6 oppositely arranged along the second direction Y. The first tapered holes 3 are also arranged on the third side surface 5, and the second tapered holes 4 are also arranged on the fourth side surface 6. The first direction X and the second direction Y intersect. Exemplarily, the third side surface 5 is the front end of the shoe upper 10, and the fourth side surface 6 is the rear end of the shoe. In these alternative embodiments, the gas can not only flow from the first side surface 1 and the second side surface 2 to achieve ventilation, but also flow from the third side surface 5 and the fourth side surface 6 to complete ventilation, which can further improve the ventilation effect.

[0039] In some alternative embodiments, the shoe upper 10 further includes a top surface 7. The top surface 7 is oppositely arranged with the sole along the third direction Z, and is connected to the first side surface 1, the second side surface 2, the third side surface 5, and the fourth side surface 6. Ventilation holes 8 communicating the shoe cavity with the outside are arranged on the top surface 7. The first direction X, the second direction Y, and the third direction Z intersect pairwise.

[0040] In these alternative embodiments, ventilation holes 8 are provided on the top surface 7. On the one hand, it can improve the ventilation effect, and on the other hand, it can also improve the aesthetic appearance of the shoe upper 10 through the patterned ventilation holes 8.

[0041] Please refer to Figure 3 , the second aspect embodiment of the present disclosure provides a ventilated shoe 100, which includes a sole 20 and a shoe upper 10 as described in any one of the foregoing first aspects, and the shoe upper 10 is connected to the sole 20. The ventilated shoe 100 has the relevant structure of the shoe upper 10 in the foregoing first aspect embodiment. Refer to the shoe upper 10 provided in the foregoing embodiments, and has all the beneficial effects of the foregoing shoe upper 10. To avoid repetition, it will not be described herein again.

[0042] In some alternative embodiments, the ventilated shoe 100 includes a left shoe and a right shoe. Among them, the macroscopic directional flow direction of the gas in the left shoe can be to the left or to the right, and the macroscopic directional flow direction of the gas in the right shoe can also be to the left or to the right.

[0043] Preferably, in order to prevent the gas discharged from the shoe cavity of the left shoe from entering the shoe cavity of the right shoe, or prevent the gas discharged from the shoe cavity of the right shoe from entering the shoe cavity of the left shoe, the large-diameter ends of the first tapered hole and the second tapered hole of the left shoe are arranged facing the left side, and the large-diameter ends of the first tapered hole and the second tapered hole of the right shoe are arranged facing the right side; or, the large-diameter ends of the first tapered hole and the second tapered hole of the left shoe are arranged facing the right side, and the large-diameter ends of the first tapered hole and the second tapered hole of the right shoe are arranged facing the left side.

[0044] As described above, the above are only the specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present disclosure should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
