Body valve, the valve is in the shape of a round tube tapering so that the end forms a necked part, and there are two slots on the necked part, so that it can use the pressure to generate one-way flow, and the rubber inflatable ball Inflate the air bag to increase the amount of inflation, and under the advantage of shortening the inflation time, the air bag of the shoe body can be made to surround the periphery and the front end of the shoe body without causing insufficient space. The disadvantages of high cost and long inflation time.

The utility model provides an improvement of the air cushion structure of sneakers. The structure includes: an air cushion, an inflatable ball and a control valve, etc., wherein the inflatable ball is respectively provided with an air suction port and an air supply port, and a valve seat is installed at the air suction port. And a soft sheet valve is embedded in the valve seat, and the air supply port of the inflatable ball is inserted into the main valve body inlet branch pipe of the control valve, and a soft elastomer valve is fixed at the inlet branch pipe. The valve is in the form of a tapered circular tube with a necked portion formed at the end, and two slits are provided on the necked portion; an exhaust port is provided at the other end of the main valve body, and a valve is installed in it. The rod is supported upward by a spring, so that the rod head of the valve rod is pressed to seal the exhaust port, and an air delivery branch pipe is set on the main valve body to connect with the conduit on the air cushion, so that when the inflatable ball is compressed, the air is released from the inflated The inside of the ball enters the main valve body through the slit of the soft elastomer valve, and then guides it into the air cushion to inflate it; when you want to remove the air in the air bag, just press the valve stem, the air will be discharged from the exhaust port, and a flow will be emitted The air cushion formed by the inflatable ball of the above structure and the control valve is made to surround the periphery of the shoe body and the upper part of the front end, forming a whole group of air cushions that can surround the shoe body.

Cooperate with drawing now and by enumerating a specific embodiment, introduce in detail the structure content of the present utility model and the function benefit that it can reach:
