[0039] Best of all, the above water-stopping and air-permeating unit comprises a first duckbill valve 11; the first duckbill valve 11 is located on the shoe sole, and the air outlet end of the first duckbill valve 11 is two flat pieces 111 connected to the lower end of the inner connecting end; the two flat pieces 111 are folded into a flat mouth shape; the first duckbill valve 11 is made of rubber material; when the air flow in the shoe enters the air collection unit 2 through the air passage unit 3 and then enters the inner connecting end of the first duckbill valve 11, the pressure in the inner connecting end increases, causing the air outlet end to deform and expand, and the two flat pieces 111 open relative to each other to exhaust air to the outside; when the air flow stops, the pressure in the air outlet end is less than the external pressure, and under the action of atmospheric pressure, the two flat pieces 111 are pressed tightly, causing the air outlet end to close, preventing external water vapor from entering; even in a water environment, water presses the two flat pieces 111 tightly, causing the air outlet end to close and preventing water from entering.

[0040] In a preferred embodiment, the air outlet end of the first duckbill valve 11 is provided with a protective structure for preventing the air outlet end of the first duckbill valve 11 from being exposed to the outside.

[0041] In a preferred embodiment, the air outlet end of the first duckbill valve 11 is easily affected by the outside world, such as stress deformation, thereby reducing the service life; in order to prolong the service life, a protective structure is provided around the first duckbill valve 11; the protective structure comprises a recessed groove 71 formed on the outer periphery of the shoe sole or a shielding device formed on the outer periphery of the shoe sole, the first duckbill valve 11 is located in the recessed groove 71 or within the shielding range of the shielding device, and the air outlet end of the first duckbill valve 11 is not in contact with the recessed groove 71 or the shielding device; the reason for not being in contact is that the two flat pieces 111 of the duckbill valve are under little stress, and if they are in contact, it may cause the internal air-permeating space to become smaller or the two flat pieces 111 may be attached to the recessed groove wall, thereby losing or reducing the air-permeating function.

[0042] Preferably, the recessed groove 51 comprises an inner recess formed on the outer periphery of the shoe sole, the air outlet end of the first duckbill valve 11 is located in the inner recess, and the flat pieces 111 of the first duckbill valve 11 are not in contact with the recessed groove wall and preferably do not protrude out of the recessed groove 51; in one scheme, the recessed groove 51 extends inwardly to form an air passage, and the air outlet end of the first duckbill valve 11 is located in the air passage; the formed air passage constitutes the protective structure of the air outlet end of the first duckbill valve 11.

[0043] In a preferred embodiment, the outer periphery of the shoe sole forms one or two protruding portions, and the air outlet end of the first duckbill valve 11 is located below the protruding portion or between the two protruding portions.

[0044] The gas collecting unit 2 is a gas collecting bag or pressure chamber 21 with a cavity. The pressure chamber 21 also includes an air outlet and an air inlet. The air outlet is in communication with the air inlet of the first duckbill valve 11. The air outlet of the pressure chamber 21 is in communication with the inner connecting end of the first duckbill valve 11. The air inlet of the pressure chamber 21 is in communication with the air passage unit 3.

[0045] In a preferred embodiment, the air passage unit 3 is an air passage with a one-way valve. For example, the one-way valve can be an air passage 31 with a Tesla valve or an air passage 31 with a Tesla valve at a local position. The air is discharged from the shoe to the gas collecting unit 2.

[0046] In a preferred embodiment, the air passage unit 3 includes an air passage with a second duckbill valve 32. That is, the air passage unit 3 includes the second duckbill valve 32 and a communication passage 33 in communication with the second duckbill valve 32. Preferably, the second duckbill valve 32 is located at an end. The second duckbill valve 32 includes an air outlet and an inner connecting end. The air outlet is in communication with the pressure chamber 21. The inner connecting end is in communication with the air passage or is integrally formed with the communication passage 33. Preferably, the air outlet of the second duckbill valve 32 extends into the pressure chamber 21. The other end of the communication passage 33 is in communication with the inside of the shoe. The second duckbill valve 32 and the communication passage 33 constitute a one-way air discharge mode. When the air flow in the shoe enters the inner connecting end of the second duckbill valve 32 through the communication passage 33, the air outlet deforms and expands due to the increase in pressure in the inner connecting end. The two flat plates open relative to each other. The air flow enters the gas collecting unit 2. When the air flow stops, the air outlet of the second duckbill valve 32 is closed mainly depending on the size of the air pressure in the gas collecting unit 2. That is, when the air pressure is large, the air will compress and close the flat plates (switching valve) of the duckbill valve.
