[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, the utility model provides a sole with breathable and waterproof functions, comprising: a sole 100, an air bag 200 and a breathable insole, the breathable insole is installed on the sole 100, the upper surface of the sole 100 is provided with a mounting groove 110 for placing the air bag 200, the upper surface of the sole 100 is provided with a first ventilation groove 130 and a second ventilation groove 120, the first ventilation groove 130 and the second ventilation groove 120 are both connected to the mounting groove 110, and one side of the sole 100 is provided with a first ventilation groove 130 and a second ventilation groove 120 connected to the first ventilation groove 130 and the second ventilation groove 120. The through hole 140 of the groove 130, the airbag 200 is installed in the installation groove 110, and the first one-way valve 210 and the second one-way valve 220 are installed on the airbag 200. The first one-way valve 210 is connected to the first ventilation groove 130, and the second one-way valve 220 is connected to the second ventilation groove 120. A first sealing film is arranged at the opening of the first ventilation groove 130, so that the first groove becomes a tubular gas channel, and a second sealing film is arranged at the opening of the second ventilation groove 120, and a ventilation hole is opened on the second sealing film. The cross-sectional shape of the side wall of the first ventilation groove 130 and the second ventilation groove 120 is an arc shape. The gas flow direction of the first one-way valve 210 and the second one-way valve 220 is to flow to the outside of the shoe at the same time or to flow to the inside of the shoe at the same time.

[0026] In this embodiment, the first one-way valve 210 is a one-way outlet valve, and the gas flows in a direction from the airbag 200 through the first one-way valve 210 and out of the through hole 140. The second one-way valve 220 is a one-way inlet valve, and the gas flows in a direction from the inside of the shoe through the second one-way valve 220 and then into the airbag 200. The airbag 200 is arranged on a side close to the heel. When the first sealing film is used to seal the opening of the first ventilation groove 130 along its length direction, it can replace the ventilation duct. Similarly, the second sealing film is used to seal the opening of the second ventilation groove 120 along its length direction, which can also replace the ventilation duct. In addition, since no ventilation duct is provided in the first ventilation groove 130 and the second ventilation groove 120, the ventilation cross-sectional area of ​​the first ventilation groove 130 and the second ventilation groove 120 is larger, that is, the ventilation volume is larger.

[0027] The gas circulation process during use is as follows:

[0028] 1. When a person steps on the airbag 200 , the airbag 200 is compressed, and the gas in the airbag 200 enters the first ventilation groove 130 through the first one-way valve 210 , and then reaches the outside of the shoe through the through hole 140 .

[0029] 2. When a person's foot moves away from the airbag 200 , the airbag 200 rebounds to generate suction, and the gas inside the shoe passes through the air holes of the breathable insole and the second sealing film into the second ventilation groove 120 , and then enters the airbag 200 through the second one-way valve 220 .

[0030] When a person walks, the foot repeatedly presses and lifts the sole 100 , and the airbag 200 repeats the above-mentioned processes 1 and 2, so that the gas in the shoe is continuously discharged.

[0031] In other embodiments, the flow direction of the gas can be opposite to the above-mentioned gas circulation process, that is, when a person steps on the airbag 200, the airbag 200 is compressed, and the gas in the airbag 200 enters the second ventilation groove 120 through the second one-way valve 220, and then enters the interior of the shoe through the air holes of the second sealing membrane and the breathable insole; when the person's foot moves away from the airbag 200, the airbag 200 rebounds to generate suction, and the gas outside the shoe passes through the first one-way valve 210 to replenish the interior of the airbag 200.

[0032] A plurality of second ventilation grooves 120 are provided on the sole 100. In this embodiment, the plurality of second ventilation grooves 120 can cover a larger area of ​​the sole 100, thereby achieving a better ventilation effect.

[0033] The first one-way valve 210 is provided with a switch for opening or closing the first one-way valve 210. In this embodiment, the sole 100 is made of waterproof material. On rainy days or other humid environments, the switch can be closed to prevent water from entering the shoe through the through hole 140 and causing damage to the interior of the shoe or causing moisture inside the shoe.

[0034] A shoe comprises a waterproof and breathable sole 100 and an upper, wherein the upper is fixedly connected to the sole 100. In this embodiment, the choice of the upper material is not restricted. When an airtight material is used as the upper, gas can still enter the shoe from the gap between the shoe and the foot, so that the gas in the sole 100 can circulate normally.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
