[0023] Please see Figure 1-7 As shown, this utility model relates to a one-way air circulation airbag sole, including a sole 1, an airbag body 2, a first air tube 3, and a second air tube 4. The airbag body 2 is provided with a first one-way flow channel 23 and a second one-way flow channel 24. In this embodiment, the first one-way flow channel 23 and the second one-way flow channel 24 are respectively the air inlet and air outlet channels, respectively, and can also be interchanged, that is, the first one-way flow channel 23 and the second one-way flow channel 24 are respectively the air outlet and air inlet channels. The first one-way flow channel 23 is connected to the first air tube 3. If the first one-way flow channel 23 is the air inlet channel, then the first air tube 3 is the first air tube; conversely, if the first one-way flow channel 23 is the air outlet channel, then the first air tube 3 is the air outlet channel. The second one-way flow channel 24 is connected to the second air tube 4. If the second one-way flow channel 24 is the air outlet channel, then the second air tube 4 is the air outlet channel; conversely, if the second one-way flow channel 24 is the air inlet channel, then the second air tube 4 is the first air outlet channel. The shoe sole 1 includes a heel portion 12 and a toe portion 11, which are integrally formed. The toe portion 11 is provided with a guide groove 111 to collect air from the toe portion 11. The heel portion 12 is provided with an air bladder groove 121, which is directly formed on the shoe sole 1. The first air tube 3 and the second air tube 4 are respectively inserted into the first one-way flow channel 23 and the second one-way flow channel 24. The air bladder body 2 covers the air bladder groove 121, and the air bladder body 2 and the air bladder groove 121 cover each other to form an air bladder cavity 5. The air bladder cavity 5 is connected to the guide groove 111 through the first air tube 3. Air from the toe portion 11 enters the air bladder cavity 5 through the first air tube 3. At the same time, the air bladder cavity 5 is connected to the outside through the second air tube 4. Air from the sole flows out of the shoe through the second air tube 4. Meanwhile, air from outside the shoe is drawn in after the air bladder cavity 5 deforms.

[0024] In this embodiment, the first one-way flow channel 23 and the second one-way flow channel 24 adopt the flow channel technology solution of the prior art CN212171014U. The airbag body 2 and the airbag groove 121 are covered to form the airbag cavity 5. The airbag cavity 5 is equivalent to the airbag body in CN212171014U. The difference between this application and CN212171014U is that the airbag body adopts a split structure. One part of the structure utilizes the space of the shoe sole, and the other part of the structure is made of elastic material (such as rubber) to form a sheet (airbag cover) with the first one-way flow channel 23 and the second one-way flow channel 24. The airbag cover is attached to the airbag groove 121 of the shoe sole by adhesive.

[0025] Depending on the specific needs of different scenarios, the one-way air circulation airbag sole achieves the same ventilation mode as CN212171014U. When walking, the foot compresses and expands the airbag cavity 5, expelling damp sweat from inside the shoe. The air holes on the sole act as air outlets, keeping feet dry and comfortable and preventing shoe odor. Alternatively, the airbag cavity 5 can draw outside air into the shoe. When the second one-way flow channel 24 is located on the outside of the shoe via the second air pipe 4 and the air holes on the sole, it utilizes the principle of walking to gradually draw outside air into the shoe through the compression and expansion of the airbag cavity 5, thus achieving ventilation and air exchange within the shoe. The specific ventilation modes are as follows:

[0026] 1. Remove the air from inside the shoe:

[0027] When the foot is lifted, the air bladder cavity 5 inflates from its flattened state, and the increased volume of the air bladder cavity 5 generates suction. At this time, the air pushes the blocking bead 25 in the air passage, the first one-way flow channel 23 (air intake channel) opens, and the second one-way flow channel 24 (exhaust channel) closes. The air inside the shoe enters the air bladder cavity 5 through the first air pipe 3 (air intake pipe) and the first one-way flow channel 23 (air intake channel).

[0028] When the foot steps on the airbag, the airbag cavity 5 is flattened from its inflated state, and the volume of the airbag cavity 5 decreases. At this time, the air pushes the blocking bead 25 of the air passage, closing the first one-way flow channel 23 (air inlet channel) and opening the second one-way flow channel 24 (air outlet channel), and the air inside the shoe is expelled from the shoe.

[0029] 2. By switching the air intake and exhaust channels, air from outside the shoe is drawn into the shoe. The principle is as follows:

[0030] When the foot is lifted, the air bladder cavity 5 inflates from its flattened state, and the increased volume of the air bladder cavity 5 generates suction. At this time, the air pushes the blocking bead 25 in the air passage, the second one-way flow channel 24 (air intake channel) opens, and the first one-way flow channel 23 (exhaust channel) closes. The air inside the shoe enters the air bladder cavity 5 through the second air pipe 4 (air intake pipe) and the second one-way flow channel 24 (air intake channel).

[0031] When the foot steps on the airbag, the airbag cavity 5 is flattened from its inflated state, and the volume of the airbag cavity 5 decreases. At this time, the air pushes the blocking bead 25 of the air passage, closing the second one-way flow channel 24 (air inlet channel) and opening the first one-way flow channel 23 (air outlet channel), and the air inside the shoe is expelled from the shoe.

[0032] In this embodiment, the sole 1 is provided with an inflow groove 13, which connects the airbag groove 121 and the guide groove 111. The first air tube 3 is embedded in the inflow groove 13. The sole 1 is provided with an air outlet groove 14, through which the airbag groove 121 is connected to the outside. The second air tube 4 is embedded in the air outlet groove 14.

[0033] In this embodiment, the flow guide 111 is distributed in a grid pattern on the foot part 11. The flow guide 111 is provided with a flow guide connection port 112. The flow guide 111 is connected to the inflow channel 13 through the flow guide connection port 112. The first air tube 3 can pass through the flow guide connection port 112 and be connected to the flow guide 111, so that the flow guide 111 is connected to the airbag cavity 5.

[0034] In this embodiment, the airbag body 2 is made of an elastic material with good elasticity. When the pressing part 22 is pressed, the pressing part 22 is deformed by pressure, which compresses the airbag cavity 5. When the pressure on the pressing part 22 is released, the pressing part 22 elastically returns to its initial position, which restores the airbag cavity 5 to its original state.

[0035] Furthermore, an airbag mounting groove 123 is provided outside the airbag groove 121, and the airbag groove 121 is disposed within the airbag mounting groove 123. The airbag body 2 includes a fitting ring 21 and a pressing part 22. The pressing part 22 is formed by protruding outwards from the surface of the fitting ring 21. The shape of the fitting ring 21 matches the airbag mounting groove 123, and the airbag body 2 is mounted within the airbag mounting groove 123 via the fitting ring 21.

[0036] Furthermore, a support member 122 is provided within the airbag groove 121. The support member 122 is made of a soft, resilient material that can be deformed by pressure. In this embodiment, the shape of the support member 122 is not limited; it can be T-shaped, O-shaped, or other shapes. The support member 122 supports the airbag body 2, preventing the airbag body 2 from deforming when not pressed. When the airbag body 2 is pressed, the support member 122 deforms with the pressure.

[0037] When the wearer steps down while walking, the heel presses down on the pressing part 22, causing it to deform under pressure and compressing the air bladder 5. The gas inside the air bladder 5 is then expelled through the second air tube 4, thus releasing the gas from the air bladder 5. When the foot is lifted, the heel no longer applies pressure to the pressing part 22, which elastically recovers, causing the air bladder 5 to expand again. At this time, the air bladder 5 provides suction, drawing the gas inside the shoe from the guide groove 111 to the first air tube 3, and then from the first air tube 3 into the air bladder 5, thereby drawing the gas inside the shoe into the air bladder 5 and achieving a ventilation effect.

[0038] This utility model relates to a one-way air circulation airbag sole. In this embodiment, an airbag groove 121 is provided at the heel part 12 of the sole 1. The airbag body 2 is covered on the airbag groove 121, so that the airbag body 2 and the interior of the airbag groove 121 form an airbag cavity 5. The airbag has low manufacturing cost and is easy to manufacture, which effectively saves production costs, can effectively shorten the production cycle, and improve production efficiency.

[0039] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
