Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing shoe sole technology, and more specifically to a one-way exhaust shock-absorbing shoe sole. Background Technology

[0002] Existing shoe sole technologies generally suffer from poor shock absorption and inadequate ventilation, especially in athletic shoes. During intense exercise, the feet are easily subjected to impact and vibration, and traditional soles cannot effectively alleviate this pressure. At the same time, the air pressure inside the shoe cannot be released in time, causing discomfort.

[0003] The existing shock-absorbing shoe sole, as shown in the patent application number CN214283603U, "A kind of exhaust shoe sole", achieves the shoe sole exhaust function by setting an air chamber, an air intake channel and a one-way exhaust channel on the lower surface of the midsole. However, its structure mainly relies on the Tesla valve passage and the mechanism without moving parts, which is relatively complex and prone to failure in complex situations. Utility Model Content

[0004] The purpose of this utility model is to provide a one-way exhaust shock-absorbing shoe sole in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a one-way exhaust shock-absorbing shoe sole, including an air chamber and a shoe sole disposed at the bottom. The air chamber includes a forefoot area for bearing force on the forefoot and a rearfoot area for bearing force on the heel, and the volume of the forefoot area is larger than that of the rearfoot area. Several air intake holes for air intake are provided through the upper part of the forefoot area. The shoe sole is provided with shock-absorbing ridges, and an exhaust channel is provided on the side of the rearfoot area. The exhaust pipe includes an outermost air outlet, an internal opening of which is equipped with a filter screen, a spring connected to one side of the air outlet, the spring being connected to a ball, and an air outlet pipe connected to the rear palm area on the side of the ball away from the spring.

[0006] As a preferred technical solution of this utility model, the shock-absorbing protrusions are only provided on the corresponding part of the sole in the forefoot area.

[0007] As a preferred embodiment of this invention, the filter screen is rectangular in shape to prevent foreign objects from entering the air chamber.

[0008] As a preferred embodiment of this utility model, the spring can press the small ball tightly against the air outlet pipe when the air pressure inside the air chamber is low, thus preventing reverse air intake.

[0009] The beneficial effects of this utility model are as follows: This invention effectively solves the problems of insufficient shock absorption and poor air pressure discharge in traditional shoe soles through its air chamber and exhaust design. The air chamber is divided into a forefoot area and a heel area, with the forefoot area having a larger volume than the heel area, which can better withstand the pressure of the foot during walking or exercise, thus improving the shock absorption effect. Multiple air inlets in the forefoot area can effectively guide air in and ensure air pressure balance within the air chamber. The shock-absorbing protrusions on the sole are only located in the forefoot area, which can effectively absorb and disperse the impact force from the ground, reduce the vibration of the foot and help the air chamber to vent smoothly; the venting system uses the venting channel and vent pipe located in the heel area to achieve one-way venting with the cooperation of springs and balls, preventing gas from entering in reverse and preventing discomfort caused by excessive air pressure.

[0012] like Figures 1 to 2 As shown, this utility model proposes a one-way exhaust shock-absorbing shoe sole 3, comprising components such as an air chamber 1, an exhaust channel 2, a shoe sole 3, shock-absorbing protrusions 4, a forefoot area 11, a heel area 12, an air inlet 13, an exhaust pipe, a filter 22, a spring 23, and a ball 24; the shoe sole 3 structure includes an air chamber 1, which is divided into a forefoot area and a heel area; the volume of the forefoot area is larger than that of the heel area. The design mainly considers that the forefoot area bears greater foot pressure, so a larger volume is needed to optimize the shock absorption effect and reduce the impact force on the foot.

[0013] The air chamber 1 is located below the sole 3, with the forefoot area at the front of the sole 3 and the heel area at the rear of the sole 3. An exhaust channel 2 is located on the side of the heel area. Multiple air inlets 13 are evenly distributed above the forefoot area 11 to guide air into the sole 3 and maintain air pressure balance within the shoe. The number and position of the air inlets 13 can be adjusted according to actual needs to ensure smooth airflow. Shock-absorbing protrusions 4 are only located at the bottom of the forefoot area 11, and their number and arrangement are designed according to the force distribution on the forefoot to effectively absorb impacts from the ground and reduce vibration. The design of the shock-absorbing protrusions 4 ensures good elasticity of the sole 3 during gait. The exhaust channel 2 on the side of the heel area is connected to the air outlet pipe 25 of the sole 3. The exhaust pipe consists of an air outlet 21, a filter screen 22, a spring 23, a ball 24, and an air outlet pipe 25. The air outlet 21 is located on the outermost layer of the air outlet pipe 25, and a filter screen 22 is installed inside. The filter screen 22 adopts a rectangular hole structure, which can effectively prevent foreign objects from entering the air chamber 1 and keep the air inside the air chamber 1 clean.

[0014] Spring 23 is located on one side of air outlet 21 and connected to ball 24. When the air pressure in air chamber 1 is high, ball 24 is compressed, and spring 23 drives ball 24 to discharge gas in one direction. Through the cooperation of spring 23 and ball 24, it is ensured that gas can only be discharged from air chamber 1 and cannot enter in the opposite direction, thus avoiding the impact of reverse air intake on comfort. The design of spring 23 ensures that when the air pressure in air chamber 1 is low, spring 23 can press ball 24 tightly to seal the outlet of air pipe 25, thereby effectively preventing reverse air intake, avoiding the backflow of gas inside the shoe, and ensuring dryness and comfort inside the shoe.

[0015] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
