[0020] A tactical boot includes a combined sole with a one-way drainage function.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] By setting the one-way discharge module and the one-way inflow module, it is ensured that the water flow can only enter the pressure cavity through the first drainage channel and the second drainage channel from the inside of the shoe, and finally discharged to the atmosphere through the one-way discharge module, effectively preventing external water from flowing back into the shoe, and the flow resistance is set in the second drainage channel to ensure that the water flow does not flow reversely, thereby further improving the reliability of the drainage system, and is particularly suitable for complex water situations that may be encountered in combat environments.

[0023] The design of the shoe midsole with the rear end higher and the front end lower, combined with the first drainage channel arranged along the inclined surface of the shoe midsole, can naturally guide the water in the shoe to flow to a lower place by gravity, ensuring that the water is quickly collected and discharged. This design significantly improves the drainage efficiency. The first drainage channel is distributed in a tree branch shape, and the design of the main branch and the branch allows water to be effectively collected and guided to the connecting channel from different areas of the shoe midsole. In particular, the branch extends to both sides of the shoe midsole, ensuring that water in the entire sole range can be discharged in time to avoid local water accumulation. The depth of the tree branch-shaped branch gradually increases from shallow to deep, which can gradually increase the fluid pressure when the water flows into the branch, promoting the water flow to flow more smoothly in the direction of the main branch. This gradual depth change helps to reduce water flow resistance and avoid backflow of water;

[0024] Using the principle of Tesla valve, the design of the main channel and the bypass channel can generate significant resistance when the fluid tries to flow in the opposite direction, effectively preventing the second drainage channel from backflowing into the shoe. Compared with traditional mechanical one-way valves, the Tesla valve does not require moving parts and relies on the fluid's own kinetic characteristics to achieve one-way control, with higher reliability, longer service life, and lower maintenance requirements.

[0025] By setting a support plate at the bottom of the pressure cavity, deformation or collapse of the outsole under pressure can be effectively prevented, thereby ensuring the stability of the entire sole structure. The thickened pressure cavity corresponding to the outer wall of the upper surface of the shoe midsole not only enhances the firmness of the overall structure, but also further improves the resilience of the pressure cavity, allowing the pressure cavity to elastically recover.

DETAILED DESCRIPTION

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the present application discloses a kind of tactical boots comprising the combined sole with one-way drainage function, referring to Figure 1 、 2 , including shoe outsole 1 and inlay in the shoe midsole 2 of outsole part, shoe outsole 1 is made of high wear-resistant puncture-resistant rubber material, not only has excellent wear resistance function, also has certain puncture-resistant function, can play the appropriate protection to foot part;Shoe outsole 1 bottom is provided with many raised anti-skid blocks, with excellent anti-skid wear resistance function, also have appropriate puncture-resistant function.

[0034] Refer to Figure 2 、 3 , the midsole made of PU material has strong water resistance and excellent deformation resistance, using it to make the midsole can effectively prevent the deformation of the sole caused by long-term soaking in water.

[0035] Refer to Figure 3 、 4 , the shoe midsole 2 is higher at the rear end and lower at the front end, the shoe midsole 2 is bonded to the shoe outsole 1 by sealing glue, the bottom surface of the shoe midsole 2 is inwardly recessed to form a sealed pressure cavity 3 with the shoe outsole 1, the fluid in the pressure cavity 3 is connected to the atmosphere by a one-way discharge module 4 provided on one side, the one-way discharge module 4 is a one-way valve that is one-way connected to the atmosphere from the pressure cavity 3, the other side of the pressure cavity 3 is provided with a one-way inflow module 5 that sucks water inside the shoe into the pressure cavity 3, the one-way inflow module 5 is a one-way valve that is one-way connected to the inside of the pressure cavity 3 by a second drainage channel 7, when the pressure cavity 3 is compressed, the one-way inflow module 5 is closed, and the one-way discharge module 4 is connected and discharges the water or air in the pressure cavity 3;When the pressure cavity 3 expands, the one-way discharge module 4 is closed, and the one-way inflow module 5 is opened, and the water inside the shoe is removed and enters the pressure cavity 3.

[0036] Refer to Figure 3 、 4 , the one-way drainage valve can be made of hard materials such as copper and iron, which has very excellent durability.

[0037] Refer to Figure 2 、 3The pressure cavity 3 is located at the heel of the insole 2, so that the cavity has a larger space, and the insole 2 is provided with a protrusion upward corresponding to the upper surface of the pressure cavity 3, and the outer wall of the pressure cavity 3 corresponding to the upper surface of the insole 2 is thickened to avoid the collapse of the top end of the cavity. The insole 2 is made of PU foaming material and has good elasticity, so that the pressure cavity 3 can generate strong pressure when being pressed, and has strong deformation recovery ability.

[0038] With reference to Figure 2 , 3 The bottom of the pressure cavity 3 is provided with a support plate 14, which is embedded between the outsole 1 and the insole 2, and abuts and supports the outsole 1 corresponding to the pressure cavity 3. The support plate 14 can be made of carbon fiber material, which can support the outsole 1 to avoid excessive deformation of the rubber when the outsole 1 corresponding to the pressure cavity 3 is extruded by the protrusion, thereby affecting the grip of the outsole. At the same time, the support plate 14 can avoid the plastic deformation of the outsole 1 caused by long-term extrusion, thereby avoiding the compression efficiency of the pressure cavity 3.

[0039] With reference to Figure 2 , 3 The upper surface of the insole 2 is provided with a first drainage channel 6 corresponding to the drainage of the wearing layer, and the first drainage channel 6 is provided in a tree shape. The main branch 10 of the tree shape is arranged obliquely along the front and rear ends of the insole 2. Water flows downward along the main branch 10 of the drainage channel by gravitational potential energy, thereby forming orderly drainage of the wearing layer.

[0040] With reference to Figure 2 , 3 The branches 11 of the tree shape are respectively connected to the main branch 10 and extend to both sides of the insole 2, and the branches 11 are inclined from top to bottom along the upper surface of the insole 2 and close to the main branch 10, thereby increasing the coverage area of the first drainage channel 6 to the wearing layer and increasing the drainage efficiency. The branches 11 are respectively directed to one side of the main branch 10, forming a channel with a depth from shallow to deep, thereby further guiding the drainage of water by gravitational potential energy.

[0041] With reference to Figure 2 , 3 The inclination of the forefoot is in accordance with the ergonomic design, and the first drainage channel 6 is inclined to the forefoot. When a person walks, the forefoot is off the ground, and the water entering the shoe can be collected from the heel and other parts to the forefoot part, and the water is unidirectionally discharged through the second drainage channel 7 connected to the pressure cavity 3.

[0042] With reference to Figure 2 , 3The second drainage channel 7 is provided on the lower surface of the insole 2, and one end thereof is communicated with one end of the one-way inflow module 5 located outside the pressure cavity 3, and the other end thereof extends towards the front end of the insole 2, that is, corresponds to the lowest end of the water flow collection position of the first drainage channel 6. The insole 2 is provided with a connecting channel communicated with the second drainage channel 7 below the insole 2 at the bottom end of the first drainage channel 6.

[0043] Referring to Figure 2 , 3 The second drainage channel 7 is a Tesla valve type, and a main channel 12 is formed on one side of the one-way drainage module 4 towards one side of the connecting channel 9. The side wall of the main channel 12 is spaced apart and extends a bypass channel 13. The extension end of the bypass channel 13 is bent and reversely connected to the main channel 12, thereby generating resistance to the fluid in the main channel 12.

[0044] Referring to Figure 2 , 3 When the water flows from the connecting channel to the drainage valve, the water flow will be divided into two paths at each loop opening, and then the two water flows will converge at the next intersection, thereby achieving acceleration. Conversely, the water flow will also be divided into two paths at the first intersection, but will converge again at the second intersection, which will form a large resistance, thereby making it difficult for the water flow to flow from the drainage valve to the connecting channel in the opposite direction, and avoiding the water in the second drainage channel 7 from flowing back to the upper side of the insole 2.

[0045] The working process of the present application is as follows: during walking, when water enters the shoe interior, the water is collected by the inclined surface of the insole 2 and the first drainage channel 6, and at the same time, when the forefoot leaves the ground, the toes are downward, accelerating the water flow in the shoe to converge, and the water converged on the forefoot flows downward into the second drainage channel 7 through the connecting channel 9.

[0046] During the movement of the foot, the water remaining in the second drainage channel 7 has a large resistance to flow towards the forefoot, so that the water cannot flow back.

[0047] When the heel lands and compresses the pressure cavity 3, the one-way valve of the one-way drainage module 4 corresponding to the pressure cavity 3 drains water outward. When the heel leaves the ground, the negative pressure generated by the elasticity of the insole 2 restores the pressure cavity 3, and the one-way valve of the one-way inflow module 5 corresponding to the pressure cavity 3 sucks the second drainage channel 7 into the pressure cavity 3, thereby realizing the function of one-way drainage of water in the shoe, and the water cannot flow back.

[0048] When there is no water in the shoe, the pressure change of the pressure cavity 3 can drive the one-way drainage of air, thereby circulating the air around the foot and having the function of auxiliary increase of air permeability.

[0049] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
