DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figures 1 to 8 As shown, the present embodiment provides an outdoor waterproof and breathable shoe, comprising an upper 100 and a sole 200, wherein a waterproof and breathable system is provided on the sole, wherein the waterproof and breathable system comprises a water-stopping and breathable unit, an air collecting unit 2, and an air duct unit 3 which are connected in sequence; the air collecting unit 2 is located at the heel, and the air duct unit 3 is a one-way exhaust duct, one end of which is connected to the inside of the shoe, and the other end is connected to the air collecting unit 2; the waterproof and breathable unit is an open and close body which is opened or closed by outdoor conditions, and comprises an air outlet end and an inner connecting end, wherein the inner connecting end is connected to the air collecting unit 2, and when the pressure in the inner connecting end is greater than the deformation force of the air outlet end, the air outlet end is opened and connected to the outside world to discharge the gas in the shoe, and when the pressure in the air outlet end is less than the outside pressure, the air is closed to prevent water from entering the shoe, and the outdoor shoe exhausts air from the inside of the shoe to the outside world through the waterproof and breathable system.

[0038] Preferably, the water-stopping and breathable unit comprises a first duckbill valve 11; the first duckbill valve 11 is located on the sole, the air outlet of the first duckbill valve 11 is two flat sheets 111 connected to the lower end of the inner connecting end, the two flat sheets 111 are gathered 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 collecting unit 2 through the airway unit 3, and then enters the inner connecting end of the first duckbill valve 11, due to the increase in pressure in the inner connecting end, the air outlet is deformed and expanded, the two flat sheets 111 are relatively opened, and exhaust is discharged to the outside, when the air flow stops, the pressure in the air outlet is lower than the outside pressure, under the action of atmospheric pressure, the two flat sheets 111 are pressed tightly, so that the air outlet is closed to prevent external water vapor from entering, even in a wading environment, water squeezes the two flat sheets 111, pressing the two flat sheets 111 tightly, so that the air outlet is closed to prevent water from entering.

[0039] 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.

[0040] In a preferred embodiment: since the air outlet end of the first duckbill valve 11 is easily affected by the outside world, such as being deformed by force, thereby reducing the service life; in order to extend the service life, the utility model sets a protective structure around the first duckbill valve 11; the protective structure includes a recessed groove 71 formed on the outer peripheral surface of the sole or a shielding device formed on the outer peripheral surface of the sole, and 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 the non-contact setting is that the two flat sheets 111 of the duckbill valve are subjected to very little force. If they come into contact, the other internal ventilation space may become smaller or the two flat sheets 111 may fit the recessed groove wall so that they are not affected by external pressure and lose or reduce the ventilation function.

[0041] Preferably, the recessed groove 51 includes an inner groove formed on the outer peripheral surface of the sole, and the air outlet end of the first duckbill valve 11 is located in the inner groove. The flat sheet 111 of the first duckbill valve 11 is not arranged in contact with the recessed groove wall, and preferably does not extend out of the recessed groove 51. In one embodiment, 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 opened air passage constitutes a protective structure for the air outlet end of the first duckbill valve 11.

[0042] In a preferred embodiment: the outer peripheral surface of the sole forms one or two protrusions, and the air outlet end of the first duckbill valve 11 is located below the protrusion or between the two protrusions.

[0043] The above-mentioned air collecting unit 2 is an air collecting air bag or pressure chamber 21 with a cavity; the pressure chamber 21 also includes an air outlet end and an air inlet end, and the air outlet end is connected to the air inlet end of the first duckbill valve 11; the air outlet end of the pressure chamber 21 is connected to the internal connection end of the first duckbill valve 11, and the air inlet end of the pressure chamber 21 is connected to the airway unit 3.

[0044] In a preferred embodiment: the airway unit 3 can be an airway with a one-way valve; for example, the one-way valve can be an airway 31 with a Tesla valve, or an airway 31 partially with a Tesla valve, which exhausts air from the inside of the shoe toward the air collecting unit 2.

[0045] In a preferred embodiment: the airway unit 3 includes an airway with a second duckbill valve 32, that is, the airway unit 3 includes the second duckbill valve 32 and a connecting channel 33 connected to the second duckbill valve 32; preferably, the second duckbill valve 32 is located at the end, and the second duckbill valve 32 includes an air outlet end and an inner connecting end; the air outlet end is connected to the pressure chamber 21, and the inner connecting end is connected to the airway or is directly integrally formed with the connecting channel 33; preferably, the air outlet end of the second duckbill valve 32 extends into the pressure chamber 21, and the other end of the connecting channel 33 is connected to the inner end of the shoe. The second duckbill valve 32 and the connecting channel 33 form a one-way exhaust method. When the airflow in the shoe enters the inner connecting end of the second duckbill valve 32 through the connecting channel 33, the pressure in the inner connecting end increases, causing the air outlet end to deform and expand, and the two flat sheets open relatively, and the airflow enters the collecting unit 2. When the airflow stops, the air outlet end of the second duckbill valve 32 is closed mainly by relying on the size of the air pressure in the collecting unit 2, that is, when the gas is large, the gas will compress and close the flat sheet (switch valve) of the duckbill valve.

[0046] The waterproof and breathable system is arranged on the sole as follows:

[0047] 1. The waterproof and breathable system is arranged on the upper surface of the sole. The upper surface of the sole is concave inward to form an air collecting groove and an airway groove.

The upper bonding sheet 51 is provided with a third connecting air hole 511 connecting the inside of the shoe and the air duct unit 3. Like the first type, if the lower bottom surface of the upper 200 is an airtight surface, a hole should also be opened to connect with the third connecting air hole 511 of the upper bonding sheet 51 or directly replace the upper bonding sheet 51 to be fitted with the sole; if it is a breathable surface, it is fitted on the upper bonding sheet 51 of the sole.

[0049] 3. The waterproof and breathable system is arranged on the lower surface of the sole. The lower surface of the sole is recessed upward to form an air collecting groove and an air duct groove.
