Detailed Implementation

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0030] like Figures 1-12 As shown, a breathable shoe sole 1 structure according to an embodiment of the present invention includes: a shoe sole 1, a filter pad 2, and a valve body mechanism 3;

[0031] The sole 1 includes a heel portion and a forefoot portion. The heel portion has a ventilation cavity. A valve body mechanism 3 is located on one side of the ventilation cavity. The valve body mechanism 3 has an air inlet and an air outlet. One end of the air inlet is connected to the ventilation cavity, and the other end is connected to an air inlet pipe. The air inlet pipe is connected to a filter pad 2, which is located on the front of the forefoot portion. One end of the air outlet is connected to the ventilation cavity, and the other end is connected to an air outlet pipe 7, which is located on the front of the heel portion and connects to the outside of the shoe.

[0032] This application features a ventilation cavity on the sole 1. When the user steps on the ground, the ventilation cavity is compressed, and the air inside the ventilation cavity is exhausted to the outside of the shoe through the air outlet 7. When the user lifts the shoe, the ventilation cavity expands, and the air inside the shoe is filtered by the filter pad 2 and enters the air inlet pipe, thus entering the ventilation cavity. This process exhausts the gas inside the shoe, and the air outside the shoe enters the shoe due to the air pressure difference, thereby improving the breathability of the shoe.

[0033] In this embodiment, the end of the air outlet pipe 7 is connected to a guide 71. The guide 71 has a hollow structure. The air inlet of the guide 71 is connected to the air outlet pipe 7. Multiple air outlets are opened on one side of the guide 71. The air outlets of the guide 71 face outwards from the shoe, guiding the gas discharged from the air outlet pipe 7 to the outside of the shoe.

[0034] like Figures 3-6 As shown, the ventilation cavity is provided with a filling pad 4, which has a porous structure and ventilation holes. The ventilation cavity is annular, and a support pad 6 is provided in the middle of the ventilation cavity. The support pad 6 is an integral structure with the sole 1.

[0035] In this embodiment, the ventilation cavity is a chamber opened inside the heel. By setting a filling pad 4 or a support pad 6 in the ventilation cavity, the sole 1 of the shoe can be effectively prevented from collapsing during use.

[0036] like Figure 12 As shown, the ventilation cavity is a groove on the front of the heel. A filling pad is provided in the groove, and a rubber sleeve 41 is fitted over the filling pad. The open end of the rubber sleeve 41 is connected to the valve body mechanism. A connecting foot 42 is provided at the bottom of the rubber sleeve 41, and the connecting foot 42 is connected to the inner wall of the groove.

[0037] By using a rubber sleeve 41 to wrap the filling pad, the user's foot presses on the rubber sleeve 41, causing the volume inside the rubber sleeve 41 to change, thereby enabling the intake and exhaust of air inside the shoe. The groove can limit the deformation of the rubber sleeve 41 and prevent damage to the rubber sleeve 41. The connecting foot 42 can fix the rubber sleeve 41 in the groove and prevent the rubber sleeve 41 from coming off the groove.

[0038] like Figures 2-6 As shown, the sole of the foot is provided with multiple filter pads 2, which are respectively located between the big toe and the second toe, between the second toe and the little toe, and at the third toe. The filter pads 2 are respectively located in the forefoot area and the plantar arch area of ​​the sole of the foot.

[0039] The valve body mechanism 3 is provided with a flow divider 5 at the air inlet, one end of which is connected to the air inlet and the other end is connected to the air inlet pipe.

[0040] The filter pad 2 is positioned to avoid areas where the foot frequently steps, thus preventing damage to the filter pad 2. The dispersed filter pad 2 can evenly expel air from inside the shoe into the ventilation chamber.

[0041] In this embodiment, the air inlet pipe can be located on the front or bottom of the foot, as long as it can allow air from inside the shoe to pass through the filter pad 2 and then into the ventilation cavity.

[0042] As Figures 4-5 shown, the length of the air inlet pipe is inversely proportional to the diameter of the air inlet pipe. The length of each air inlet pipe is the same.

[0043] By inversely proportional the length of the air inlet pipe to the diameter of the air inlet pipe, the same air flow of the air inlet pipe can be ensured, and the suction of each air inlet pipe is the same when the air cavity is expanded. By the same length of each air inlet pipe, the same suction of the air inlet pipe is ensured.

[0044] As Figures 7-10 shown, the air inlet and the air outlet of the valve body mechanism 3 are provided with check valves 31. The air inlet and the air outlet of the valve body mechanism 3 are provided with one-way pipes 32, one end of the one-way pipe 32 is a circular pipe, and the other end is flat.

[0045] By setting the check valve 31 or the one-way pipe 32, the gas backflow can be effectively avoided, and the gas in the shoe can be smoothly discharged.

[0046] The above, with reference to Figures 1-12 a kind of air-permeable shoe sole 1 structure according to the embodiments of the utility model is described, the present application is provided with air cavity on shoe sole 1, user will compress air cavity when treading ground, air in air cavity is discharged to shoe outside by air outlet pipe 7, air cavity will be expanded when user lifts shoe, the air in shoe is filtered into air inlet pipe after filtering pad 2, to enter air cavity, realize the gas in shoe is discharged, the air outside shoe enters shoe due to air pressure difference, to improve the air permeability of shoe.
