Description

Technical Field

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

[0002] Shoes are a necessity in people's daily lives, and their comfort affects people's sense of happiness in life. When people walk and exercise, the soles of their feet will inevitably sweat; therefore, the breathability of shoes also affects their comfort. Most existing shoes improve the breathability of shoes by changing the fabric of the shoes or setting openings and one-way valves in the shoes. Since the soles of the feet usually sweat, the effect of improving the breathability of shoes by changing the fabric of the shoes is limited. Regarding the method of setting an airway, an airbag and a one-way valve in the shoe to discharge sweat in the shoe, the one-way valve is installed in the airway. Every time the foot steps on the airbag in the sole, the gas in the shoe is discharged outside the shoe through the airway, which makes the one-way valve have a high operating frequency and is prone to aging. In addition, since the airway is connected to the outside world, dust can easily enter the one-way valve, causing the one-way valve to fail. Summary of the Invention

[0022] 6. A waterproof and breathable cloth is provided to cover the openings of each air inlet and one end of the upper surface of the sole body, which does not affect the air intake of the air inlet. In actual use, if external water accidentally enters the air inlet from the one-way channel, it can prevent water from entering the shoe and wetting the sole of the foot.

[0023] 7. An insole is placed on top of the waterproof and breathable cloth to increase the comfort of the sole; and a number of ventilation holes are provided on the insole.

[0024] During actual use, sweat passes through the waterproof breathable fabric through the vents and enters the air inlet.

[0025] 8. The shoe comprises the above-mentioned sole, and thus has all the beneficial effects of the above-mentioned sole. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment one:

[0045] See also Figure 1 , Figure 1 The shoe sole 100 is shown to include a sole body 1 , a waterproof and breathable fabric 2 and an insole 3 .

[0046] like Figure 1 and Figure 2 As shown, the sole body 1 is provided with an exhaust channel 11, which includes a one-way channel 111 and a plurality of air inlet channels 112. The one-way channel 111 is a Tesla valve structure, with its first end extending to the sidewall of the sole body 1 and having an exhaust port opening therein. The direction of the one-way channel 111 toward the exhaust port is the conduction direction. Each air inlet channel 112 is arranged along the conduction direction of the one-way channel 111, with one end opening on the upper surface of the sole body 1 and the other end communicating with the one-way channel 111.

[0047] In this embodiment, if Figure 1 and Figure 2As shown, a first exhaust channel group 11 and a second exhaust channel group 11 are provided in the sole body 1. Each of the first exhaust channel group 11 and the second exhaust channel group 11 includes a plurality of exhaust channels 11. The first end of each one-way channel 111 in the first exhaust channel group 11 opens to the inner sidewall of the sole body 1; the first end of each one-way channel 111 in the second exhaust channel group 11 opens to the outer sidewall of the sole body 1.

[0048] like Figure 1 and Figure 2 As shown, the number of one-way channels 111 in the first exhaust channel group 11 is equal to the number of one-way channels 111 in the second exhaust channel group 11; and each one-way channel 111 in the first exhaust channel group 11 and the second exhaust channel group 11 are arranged at intervals along the length direction of the sole body 1.

[0049] In this embodiment, if Figure 1 and Figure 2 As shown, the first exhaust channel 11 group and the second exhaust channel 11 group are provided, so that both the inside and outside of the sole 100 can be exhausted, and the exhaust effect is better. The number of one-way channels 111 in the first exhaust channel 11 group is equal to the number of one-way channels 111 in the second exhaust channel 11 group, so that the exhaust effect inside and outside the sole 100 is more uniform.

[0050] Furthermore, if Figure 1 and Figure 2 As shown, each one-way channel 111 extends laterally from the middle portion of the sole body 1 to the sidewall of the sole body 1; and each one-way channel 111 is inclined downward from the middle portion of the sole body 1. The air inlet 112 extends vertically, which facilitates the flow of gas from the air inlet 112 into the one-way channel 111. It should be understood that in this embodiment, the length direction of the sole body 1 is the longitudinal direction, and the direction perpendicular to the length direction of the sole body 1 is the transverse direction.

[0051] like Figure 1 and Figure 2 As shown, the waterproof breathable fabric 2 is positioned on the upper surface of the sole body 1, with its periphery fixedly connected to the periphery of the sole body 1. The waterproof breathable fabric 2 covers one end of each air inlet 112 opening on the upper surface of the sole body 1. The waterproof breathable fabric 2 is provided to cover one end of each air inlet 112 opening on the upper surface of the sole body 1 without affecting air intake through the air inlet 112. In actual use, if external water accidentally enters the air inlet 112 through the one-way passage 111, it can prevent the water from entering the shoe 5 and wetting the sole of the foot.

[0052] like Figure 1 and Figure 2As shown, the outer periphery of the insole 3 is sealed to the outer periphery of the sole body 1 and the waterproof breathable fabric 2. The insole 3 is provided with a plurality of ventilation holes 31 at least in the area corresponding to the waterproof breathable fabric 2. The ventilation holes 31 extend through the upper and lower surfaces of the insole 3. The insole 3 is arranged above the waterproof breathable fabric 2 to increase the comfort of the sole 100.

[0053] In actual use, such as Figure 1 and Figure 2 As shown, the sole body 1 includes an upper sole 15 and a lower sole 16 fixed to each other. The bottom end of the upper sole 15 is provided with a first inclined wall 161 and a second inclined wall 162 inclined downward from the middle. The first inclined wall 161 and the second inclined wall 162 are located at the side overlapped in the middle of the bottom end of the upper sole 15. Each one-way channel 111 of the first exhaust channel 11 group is provided on the first inclined wall 161, and each one-way channel 111 of the second exhaust channel 11 group is provided on the second inclined wall 162. Each one-way channel 111 of the first exhaust channel 11 group and each one-way channel 111 of the second exhaust channel 11 group are respectively arranged on the first inclined wall 161 and the second inclined wall 162 in a one-to-one correspondence, so that the exhaust effect on the inside and outside of the sole 100 is more uniform. The air inlet duct 112 is provided on the upper base 15 and is located above each one-way channel 111; as shown in FIG*, one end of each air inlet channel passes through the upper surface of the upper base 15, and the other end extends in the vertical direction to communicate with the corresponding one-way channel 111.

[0054] like Figure 1 and Figure 2 As shown, the top wall of the lower bottom 16 is in contact with the bottom wall of the upper bottom 15 .

[0055] like Figure 1 and Figure 2 As shown, due to the exhaust channel 11 being provided in the sole 100, the sole 100 has an exhaust function. The one-way channel 111 adopts a Tesla valve structure, which does not need to be provided with an air bag and a one-way valve in addition to prevent water from entering the sole 100. During daily use, the function of the one-way exhaust outside the sole 100 is not easy to lose effectiveness. When the sole 100 of this embodiment is actually used, when the sole sweats and produces sweat, the sweat enters the one-way channel 111 from the air inlet 112 after passing through the waterproof breathable cloth 2 through the air vent 31 on the insole 3, and is discharged from the sole 100 through the exhaust port of the one-way channel 111. Each one-way channel 111 is arranged to tilt downward from the middle part of the sole body 1, which helps the gas in the sole 100 to be discharged, while making it difficult for water from the outside to enter the sole 100.

[0056] Example 2:

[0057] like Figure 1 、 Figure 2 and 3As shown, the difference between this embodiment and the first embodiment lies in the structure of the sole body 1 and the location of the exhaust channel 11. In this embodiment, the sole body 1 includes an upper sole 15 and a lower sole 16 fixed to each other.

[0058] Among them, Figure 3 As shown, each air inlet duct 112 is provided on the upper base 15 , and the air inlet duct 112 vertically penetrates the upper surface and the lower surface of the upper base 15 .

[0059] like Figure 3 As shown, the top of the lower sole 16 is provided with a third inclined wall 163 and a fourth inclined wall 164 that slope downward from the middle. The third inclined wall 163 and the fourth inclined wall 164 are located on the sides of the middle portion of the top of the lower sole 16 and overlap. The one-way channels 111 of the first exhaust channel 11 group are provided on the third inclined wall 163, and the one-way channels 111 of the second exhaust channel 11 group are provided on the fourth inclined wall 164. Each one-way channel 111 of the first exhaust channel 11 group and each one-way channel 111 of the second exhaust channel 11 group are arranged on the third inclined wall 163 and the fourth inclined wall 164, respectively, in a one-to-one correspondence, thereby achieving more uniform exhaust on both the inside and outside of the sole 100. The top wall of the lower sole 16 is in contact with the bottom wall of the upper sole 15.

[0060] The remaining structures of the sole 100 of this embodiment are the same as those of the first embodiment, and the method of use is also the same as that of the sole 100 of the first embodiment.

[0061] Example 3:

[0062] like Figure 1 、 Figure 2 and Figure 4 As shown, the difference between this embodiment and the first embodiment lies in the structure of the sole body 1 and the location of the exhaust passage 11. In this embodiment, the sole body 1 includes an exhaust module 17, an upper sole 15 and a lower sole 16 fixedly connected as one body.

[0063] Among them, Figure 4 As shown, the top of the exhaust module 17 is provided with a fifth inclined wall 171 and a sixth inclined wall 172 that slope downward from the middle. The fifth inclined wall 171 and the sixth inclined wall 172 overlap on the sides of the middle portion of the top of the exhaust module 17. The one-way channels 111 within the first exhaust channel 11 are provided on the fifth inclined wall 171; the one-way channels 111 within the second exhaust channel 11 are provided on the sixth inclined wall 172. The one-way channels 111 of the first exhaust channel 11 group and the one-way channels 111 of the second exhaust channel 11 group are arranged on the fifth inclined wall 171 and the sixth inclined wall 172, respectively, in a one-to-one correspondence, thereby achieving more uniform exhaust on both the inside and outside of the sole 100.

[0064] like Figure 4As shown, the air inlet 112 is provided on the upper base 15 and vertically passes through the upper and lower surfaces of the upper base 15. A receiving groove 165 is provided at the bottom end of the upper base 15, opening toward the lower base 16 and passing through the inner and outer side walls of the upper base 15.

[0065] like Figure 4 As shown, the upper surface of the lower base 16 is in contact with the lower surface of the upper base 15 , and the upper surface thereof and the receiving groove 165 are enclosed to form a first cavity adapted to the exhaust module 17 .

[0066] like Figure 4 As shown, the exhaust module 17 is placed in the first cavity.

[0067] The remaining structures of the sole 100 of this embodiment are the same as those of the first embodiment, and the method of use is also the same as that of the sole 100 of the first embodiment.

[0068] Example 4:

[0069] like Figure 5 As shown, this embodiment provides a shoe 5 having the sole 100 described in any one of the above-mentioned embodiments 1 to 3. In this embodiment, the shoe 5 using the structure of the sole 100 of embodiment 2 is taken as an example to illustrate the shoe 5 in this embodiment.

[0070] like Figures 1 to 5 As shown, the shoe 5 of this embodiment includes an upper 4 and a sole 100. The upper 4 is fixedly connected to the periphery of the upper surface of the sole 100 and encloses the upper surface of the sole 100 to form a shoe cavity. The air inlet 112 of the sole 100 is opened at one end of the upper surface of the sole body 1 and communicates with the shoe cavity. Specifically, when the shoe 5 of this embodiment is actually used, when people are walking, the soles of their feet are prone to sweating and generating sweat. The sweat in the shoe cavity passes through the air vents 31 on the insole 3 through the waterproof breathable cloth 2, enters the one-way channel 111 through the air inlet 112, and is discharged from the exhaust port in the one-way channel 111.

[0071] Since this embodiment has the sole 100 of the above-mentioned embodiments 1 to 3, it has all the beneficial effects of the above-mentioned embodiments 1 to 3.

[0072] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
