Referring to fig. 1 to 8, the present invention relates to an air bag ventilation structure, and an insole and a shoe thereof. Wherein the gasbag structure of taking a breath has first gasbag 1 and second gasbag 2, can set up relief valve 3, pressure differential valve 4 and gas damper 5 two by two between first gasbag 1 and the second gasbag 2. Thereby achieving different motion states and generating corresponding energy feedback. The pressure release valve 3, the differential pressure valve 4, the gas damper 5 and the first air bag 1 and the second air bag 2 are all made by bonding or integration, so that the cost is low and the manufacture is convenient.
Specifically referring to fig. 4, the relief valve 3 includes a tube 61, a valve 62 that is formed in a stepped shape by contracting in the tube 61, and a piston 63 that is movable back and forth, wherein a spring 64 is provided between the piston 63 and the tube 61, the spring 64 is used to return the piston 63, and the piston 63 blocks the valve 62 when the spring 64 is in a natural state. The piston 63 is arranged at one side close to the second air bag 2, the valve 62 is arranged at one side close to the first air bag 1, and the pressure relief valve 3 is similar to a one-way valve, so that the piston 63 can be rapidly pushed to move by the air pressure generated by the first air bag 1. The relief valve belongs to prior art, but current relief valve is mostly metal component, and the structure is complicated, need do the improvement of adaptability to the relief valve in the application field of difference, and 3 simple structure makeups of relief valve in this embodiment are convenient.
Specifically referring to fig. 5, the differential pressure valve 4 includes a tube 61, a valve 62 formed in a stepped shape by contracting in the tube 61, and a piston 63 capable of reciprocating, wherein a spring 64 is provided between the piston 63 and the tube 61, the spring 64 is used for returning the piston 63, and the piston 63 and the valve 62 have a gap when the spring 64 is in a natural state. The piston 63 is located at a side close to the first airbag 1 and the valve 62 is located at a side close to the second airbag 2, so that the piston 63 can be rapidly pushed by the air pressure generated by the first airbag 1.
The gas damper 5 has two principles, one is to slow down the flow rate by flowing gas through a long narrow pipe, and the other is to counteract the impact by gas recoil. Referring specifically to fig. 6, the gas damper 5 includes a tubular body 61, and the inner diameter of a section of the tubular body 61 is narrowed to form a narrow flow path, and the inner diameters of both ends of the tubular body 61 are larger than the narrow flow path, and the narrow flow path serves as a speed reduction member. This corresponds to the first principle. Referring specifically to fig. 6, the side wall of the gas damper 5 is provided with a plurality of elbows 65, when the inlet of the elbow 65 is along the gas flow direction and the outlet is against the gas flow direction, the gas flow is blocked, otherwise, the gas flow velocity is not affected. In fig. 7, the elbow 65 at the left end of the gas damper 5 blocks the flow of gas from left to right, and the elbow 65 at the right end blocks the flow of gas from right to left, and two elbows 65 with opposite inlet directions are respectively arranged, so that the bidirectional flow blocking of gas is realized, and the elbow 65 serves as a speed reduction part. The gas damper 5 of fig. 5 is simple to manufacture and more practical.
Referring to fig. 1, set up relief valve 3 and gas damper 5 between first gasbag 1 and the second gasbag 2, when first gasbag 1 received big impact, relief valve 3 switched on and can reduce the resilience of first gasbag 1 to the foot, and is more comfortable, when receiving little impact, relief valve 3 blockked up and makes first gasbag 1 remain most gas, provides great resilience volume, also can become comfortable. After a third transposed pressure relief valve 3 is additionally arranged between the first air bag 1 and the second air bag 2, namely, the port of the pressure relief valve 3 is exchanged, when the second air bag 2 is impacted, the above effect can be brought. The air bag ventilation structure is mainly used in sports shoes, can effectively protect feet of athletes, and is favorable for sports bouncing.
