Abstract
Description
Technical Field
[0001] The present invention relates to a sole with a drainage function. Background Art
[0002] At present, there are many waterproof shoe products on the market. Although they have good waterproof performance, in relatively deep waters, such as beaches and shallow bays where the water depth is higher than the height of the boot tube, no matter how tightly the tube mouth is tied, water will inevitably enter the shoe from the tube mouth. Moreover, after re-entering dry land, the water cannot be immediately drained from the shoe, which increases the weight of the feet, reduces the action efficiency, and thus affects the reaction ability. If in action, it is easy to affect the achievement of the action goal. Some drainage shoe products have also appeared in the prior art, but they all have simple drainage ports and poor drainage effects. For example:
[0003] The Chinese invention patent application with the application publication number CN102342621A discloses a drainage and quick-drying shoe, which mainly has one-way drainage holes on the sole, and the bottom end face of the insole installed in the shoe body has water-permeable holes and grooves, and the grooves are communicated with the one-way drainage holes at the bottom of the shoe. When water enters the shoe body, it enters the grooves through the water-permeable holes and is discharged through the one-way drainage holes. Summary of the Invention
[0004] The purpose of the present invention is to provide a sole structure that can drain water.
[0005] To solve the above problems, the present invention provides a sole with a drainage function, which is characterized in that it includes a sole body and a drainage mechanism arranged on the sole body. Among them, the sole body is composed of a midsole and / or an outsole, and it at least includes a drainage groove arranged on its upper surface and a drainage hole arranged on its outer surface or bottom surface; the drainage mechanism includes:
[0006] A drainage body located inside the sole body. The drainage body includes a housing and a hollow cavity located inside the housing. At least the first housing constituting the upper part of the housing is made of an elastic material, and the first housing is configured to be able to deform downward by depression when subjected to a downward external force, and at least part of the first housing can rebound upward when the acting force is removed;
[0007] A water inlet pipeline connecting the drainage groove and the drainage body;
[0008] A water outlet pipeline connecting the drainage hole and the drainage body;
[0009] A first one-way valve connected between the water inlet pipeline and the drainage body, and the first one-way valve is used to restrict the medium from flowing from the drainage body into the water inlet pipeline;
[0010] A second one-way valve connected between the water outlet pipe and the drainage body, the second one-way valve being configured to restrict the medium from flowing from the water outlet pipe into the drainage body.
[0011] As a further improvement of the present invention, an elastic element is disposed in the cavity, and two ends of the elastic element are respectively supported between the bottom inner wall of the outer shell and the top inner wall of the first housing. The elastic element is configured such that when an external force presses the housing downward, the elastic element is compressed and stores elastic force, and when the external force is removed, the elastic force is released to restore the first housing to its original state.
[0012] As a further improvement of the present invention, the sole body is a midsole, which is made of an elastic material at least in the rear-foot part. The sole body is provided with an installation groove for placing the drainage mechanism on the lower surface of its rear foot. The water inlet pipe is a circular tubular structure, which passes through a through hole in the sole body and communicates with the drainage groove on the upper surface of the sole body.
[0013] As a further improvement of the present invention, the water outlet pipe is a circular tubular structure, and one end thereof is inserted into the drainage hole.
[0014] As a further improvement of the present invention, the drainage body is provided with a first slot and a second slot communicating with the cavity. One ends of the water inlet pipe and the water outlet pipe are respectively inserted into the first slot and the second slot, and the first one-way valve and the second one-way valve are respectively disposed in the first slot and the second slot.
[0015] As a further improvement of the present invention, the first housing is an upwardly convex arc-shaped structure.
[0016] As a further improvement of the present invention, the elastic element is a spring.
[0017] As a further improvement of the present invention, a gasket is further disposed above the sole body. The gasket has water outlet holes penetrating through its upper and lower surfaces, and the water outlet holes are at least partially communicated with the drainage groove.
[0018] As a further improvement of the present invention, the gasket is integrally or independently and separably disposed on the upper surface of the sole body.
[0019] As a further improvement of the present invention, a plurality of drainage grooves are provided, and the drainage grooves are interconnected by being cross-arranged.
[0020] The beneficial effects of the present invention are as follows. In the present invention, the accumulated water inside the shoe converges in the drainage groove, and the drainage groove is communicated with a drainage body inside the sole through a water inlet pipeline. The drainage body is provided with a hollow outer shell, and the upper part of the outer shell is a first shell made of an elastic material. The drainage body is communicated with a drainage pipeline provided with a second one-way valve. When the foot steps down on the first shell, the gas and water in the inner cavity of the drainage body can be discharged through the drainage pipeline and the drainage holes. When the foot is lifted, when the stepping pressure is removed, during the process of the drainage body returning to its original state, the water in the drainage groove is sucked into the drainage body through the water inlet pipeline. The water inlet pipeline is provided with a first one-way valve, which can limit the water in the drainage body from flowing back into the drainage groove. The present invention can realize water absorption and drainage, effectively improving the drainage effect of the sole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.
[0029] Embodiment 1
[0030] As Figures 1-4 shown, in this embodiment, it includes a sole body 200 and a drainage mechanism 100 provided on the sole body 200. Among them, the sole body 200 is composed of a midsole (it can also be an outsole), and the sole body 200 at least includes a drainage groove 204 provided on the upper surface and drainage holes 206 provided on its outer surface.
[0031] The drainage mechanism 100 includes: a drainage body 106 located within the sole body 200, a water inlet pipe 102 connecting the drainage groove 204 and the drainage body 106, a water outlet pipe 104 connecting the drainage hole 206 and the drainage body 106, a first one-way valve connected between the water inlet pipe 102 and the drainage body 106, and a second one-way valve connected between the water outlet pipe 104 and the drainage body 106.
[0032] The drainage body 106 includes a housing 107 and a hollow cavity 108 located within the housing 107. The first housing 110 that forms the upper part of the housing 107 is made of an elastic material and is configured to be able to deform downward when subjected to a downward external force, and at least part of the first housing 110 can rebound upward when the acting force is removed.
[0033] In this embodiment, the first one-way valve is used to restrict the medium from flowing from the drainage body 106 into the water inlet pipe 102; the second one-way valve is used to restrict the medium from flowing from the water outlet pipe 104 into the drainage body 106.
[0034] Specifically, when the user wades through water while wearing this shoe or for other reasons causes water to accumulate inside the shoe, the water can be drained by normal walking. That is, when the user steps on the sole, the upper part of the drainage body 106 in the midsole, namely the first housing 110, is squeezed and deformed, resulting in a decrease in the volume and an increase in air pressure inside the cavity 108. Since the first one-way valve isolates the possibility of water and other media inside the cavity 108 flowing back into the water inlet pipe 102, the water and other media inside the cavity 108 can only be discharged through the water outlet pipe 104. On the contrary, when the user lifts the foot, the force exerted by the sole on the sole body 200 is removed, and the first housing 110 on the drainage body 106 resets upward, the air pressure inside the cavity 108 becomes smaller, and the medium in the water inlet pipe 102 is sucked into the drainage body 106, while the medium in the water outlet pipe is restricted from flowing back due to the second one-way valve.
[0035] In this embodiment, the accumulated water inside the shoe converges in the drainage groove 204 and is further discharged into the drainage body 106 through the water inlet pipe 102 connected to the drainage groove 204, thereby achieving the effect of sole drainage. In another embodiment of the present invention, a plurality of drainage grooves 204 are provided, and the drainage grooves 204 are interconnected by cross - setting. By setting more drainage grooves 204, the drainage grooves 204 are connected and converge, facilitating the discharge of accumulated water.
[0036] Embodiment 2
[0037] As Figure 5As shown, the difference between this embodiment and Embodiment 1 is that an elastic element 112 is provided in the cavity 108. Both ends of the elastic element 112 are respectively supported between the bottom inner wall and the top inner wall of the first housing 110. The elastic element 112 is configured such that when an external force presses the housing downward, the elastic element 112 is compressed to store elastic force, and when the external force is removed, the elastic force is released to restore the first housing 110 to its original state. Generally, the elastic element 112 can be a spring, which can not only provide damping for the extrusion deformation of the drainage body 106, but also provide a spring force for the reset of the first housing 110, effectively improving the sensitivity of the drainage body 106 to work, and thus improving the drainage effect.
[0038] Embodiment 3
[0039] As Figure 6 shown, in this embodiment, a gasket 208 is further provided above the sole body 200. The gasket 208 has water outlet holes 210 penetrating through its upper and lower surfaces, and the water outlet holes 210 are partially communicated with the drainage groove 204. In this embodiment, after the shoe wades through water or due to other reasons, the accumulated water on the sole flows into the drainage groove 204 through the water outlet holes 210 in the gasket 208, thereby playing a role in draining water. In another embodiment of the present invention, the gasket 208 is integrally provided on the upper surface of the sole body 200. Of course, it can also be separately provided. The integral setting can achieve a better drainage effect, while the separate setting is convenient for maintenance.
[0040] Embodiment 4
[0041] In this implementation, the rear foot part is made of an elastic material. The sole body 200 is provided with an installation groove for placing the drainage mechanism 100 on the lower surface of its rear foot. The water inlet pipeline 102 is a circular tubular structure, and it passes through a through hole in the sole body 200 and is communicated with the drainage groove 204 on the upper surface of the sole body 200.
[0042] Embodiment 5
[0043] In this embodiment, the drainage body 106 is provided with a first slot and a second slot communicated with the cavity 108. The water inlet pipeline 102 and the water outlet pipeline 104 are respectively installed in the first slot and the second slot, and the first one-way valve and the second one-way valve are respectively arranged in the first slot and the second slot. With this structure, the installation of the drainage body 106 with the water inlet pipeline 102, the water outlet pipeline 104, the first one-way valve and the second one-way valve is realized, and the structure is simpler.
[0044] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be construed in any way as a limitation on the protection scope of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the present invention.
