By pulling the zipper head one 3 to slide on the outer wall of the zipper whole 2, the protective cover 1 can be disassembled, making it convenient to replace or clean the protective cover 1. By inflating the lower inflatable pad 4 or the lower inflatable pad 4 and the lower zipper 5 at the same time, the height of the foot pad can be adjusted. The two sides of the lower inflatable pad 4 and the upper inflatable pad 6 are provided with the zipper head one 3, the upper zipper 7 and the zipper head two 8. When only the lower inflatable pad 4 needs to be inflated, the lower zipper 5 and the upper zipper 7 can be pulled by the zipper head two 8, so that the lower zipper 5 and the upper zipper 7 are combined together, which compresses and stores the upper inflatable pad 6, preventing the upper inflatable pad 6 from being dislocated when there is no air, and keeping the relative position between the inflatable layers consistent, preventing the surface of the inflatable foot pad from collapsing or bending, ensuring the stability of the structure. At the same time, the thigh can be placed on the inclined position of the outer wall of the foot pad, preventing the leg from being suspended and causing soreness.

[0026] With reference to Figure 2 , the support assembly includes a clamping plate 9, the lower surface of the clamping plate 9 is fixedly connected to the upper surface of the upper inflatable pad 6, and the upper surface of the clamping plate 9 is fixedly connected with a sponge pad 10. The outer walls of the clamping plate 9 and the sponge pad 10 are arranged on the inner wall of the protective cover 1.

[0027] Specifically, the clamping plate 9 can enhance the stability of the overall structure of the lower inflatable pad 4 and the upper inflatable pad 6, ensure that the foot pad will not be excessively bent or lose its shape, and provide support for the foot pad. The sponge pad 10 can provide comfort, cushioning and support for the feet.

[0028] With reference to Figure 3 and Figure 4 , the inner part of the lower inflatable pad 4 and the upper inflatable pad 6 is fixedly connected with a frame 11, and the inner part of the frame 11 is provided with an air inlet groove 12. The inner wall of the frame 11 is fixedly connected with a spring 13, the outer wall of the spring 13 is fixedly connected with a circular plate 14, the outer wall of the circular plate 14 is fixedly connected with a sealing ring 15, the outer wall of the sealing ring 15 is slidably connected with the inner wall of the frame 11, the inner wall of the frame 11 is provided with an air cylinder 16, the outer wall of the air cylinder 16 is arranged on the outer wall of the circular plate 14, the outer wall of the frame 11 is fixedly connected with a connecting ring 17, the outer wall of the connecting ring 17 is rotatably connected with a sealing cylinder one 18, the outer wall of the sealing cylinder one 18 is arranged on the inner wall of the frame 11, the inner part of the lower inflatable pad 4 and the upper inflatable pad 6 is fixedly connected with an air outlet cylinder 19, and the outer wall of the air outlet cylinder 19 is provided with a sealing cylinder two 20.

[0029] Specifically, the frame 11 can play a supporting role to the spring 13, and the spring 13 can push the circular plate 14 and the sealing ring 15 to block the air inlet groove 12, so that the air in the inside does not leak from the air inlet groove 12. When air charging is needed, the air charging cylinder 16 is rotated on the inner wall of the frame 11, and through the thread, the air charging cylinder 16 is slowly pushed forward on the inner wall of the frame 11. The movement of the air charging cylinder 16 pushes the circular plate 14 to extrude the spring 13. When the circular plate 14 slides through the air inlet groove 12 and the sealing of the air inlet groove 12 is released, the air charging cylinder 16 can deliver air into the inside of the air charging layer to charge air. When the air charging is finished, the spring 13 can push the circular plate 14 to seal the air inlet groove 12 again to prevent leakage, avoid unnecessary air loss during the air charging process, prevent the height or hardness of the foot pad from changing, and ensure the consistency of the user experience. Then the sealing cylinder 18 is rotated on the inner wall of the frame 11, and through the thread, the sealing cylinder 18 is locked on the inner wall of the frame 11, so that the air inlet groove 12 can be completely sealed. When air release is needed, the sealing cylinder 20 is first rotated, and through the thread, the air inlet groove 12 is separated from the air outlet cylinder 19. When the sealing cylinder 20 finishes sealing the air outlet cylinder 19, air can be released through the air outlet cylinder 19.

[0030] Working principle: when the foot pad is needed, first, the user inflates the lower air cushion 4 and the upper air cushion 6 according to the height of the user's own needs, and adjusts the height of the foot pad by inflating the lower air cushion 4 and the upper air cushion 6, when the user does not need to use the upper air cushion 6, pull the zipper head two 8, let the zipper head two 8 drive the upper zipper 7 and the lower zipper 5 to merge and compress the upper air cushion 6 to prevent the upper air cushion 6 from being dislocated, and ensure the stability of the structure, when the user needs to inflate the lower air cushion 4 and the upper air cushion 6, first use the air pump 16 to screw on the inner wall of the frame 11, and the air pump 16 moves on the inner wall of the frame 11, which drives the circular plate 14 and the sealing ring 15 to slide, when the circular plate 14 and the sealing ring 15 slide through the air inlet groove 12, the sealing of the air inlet groove 12 is released, and the air pump 16 can deliver air, which is delivered to the inside of the air layer through the air inlet groove 12, when the inflation is finished, move the air pump 16 out, so that the spring 13 pushes the circular plate 14 and the sealing ring 15 to seal the air inlet groove 12, then put the sealing cylinder one 18 into the inner wall of the frame 11 and screw, and then fix it, which can be completely sealed, when deflation is needed, rotate the air outlet cylinder 19 to make the air outlet cylinder 19 away from the sealing cylinder two 20, and then deflate through the sealing cylinder two 20, that is, the device can not only inflate the single layer air layer or the double layer air layer to adjust the height of the foot pad, but also can avoid the dislocation of the upper air layer to affect the stability of the structure when using the single layer air, and the spring 13 can push the circular plate 14 and the sealing ring 15 to automatically close the air inlet, prevent air leakage, avoid unnecessary air loss in the inflation process, and ensure the consistency of user experience.
