[0030] In this embodiment, the ventilation mechanism includes an end cap 6 fixedly mounted on the inner wall of the top end of the mounting tube 2, a U-shaped tube 11 is fixedly mounted on the upper surface of the end cap 6, a plurality of connecting tubes 12 connected to the interior thereof are evenly fixedly mounted on the upper surface of the U-shaped tube 11, a U-shaped groove 14 for the plurality of connecting tubes 12 to pass through is formed through the upper surface of the buffer pad 104, an outlet tube 13 is fixedly mounted on the outer surface of the U-shaped tube 11 away from the end cap 6, the outlet tube 13 passes through the buffer pad 104 from the rear of the heel and extends upward to the outside of the shoe shaft 103, and the extending portion of the outlet tube 13 is sewn on the shoe shaft 103. On the outside, a ventilation assembly is installed inside the mounting tube 2, and the ventilation assembly includes a piston cylinder 7 fixedly mounted on the lower surface of the end cover 6, a movable cylinder 3 is movably mounted on the inner wall of the mounting tube 2, and the movable cylinder 3 is sleeved on the outside of the piston cylinder 7, and a rubber pad 4 is fixedly mounted on the bottom end of the movable cylinder 3, and a piston 5 is fixedly mounted on the bottom plate of the movable cylinder 3, and the piston 5 is inserted into the interior of the piston cylinder 7 and slidably mounted with the inner wall thereof, a limiting assembly is installed between the movable cylinder 3 and the mounting tube 2, and a compression spring 8 is sleeved on the outer surface of the piston cylinder 7, and the compression spring 8 is fixedly mounted between the end cover 6 and the bottom wall of the movable cylinder 3.

[0031] When in use, the user can continuously press the rubber pad 4 up and down when stepping and walking, so that the piston 5 installed in the movable cylinder 3 can make a piston movement in the piston cylinder 7, so that the piston cylinder 7 can continuously inhale or blow air into the inside of the shoe body 1 through the U-shaped tube 11 and the connecting tube 12, and the outside air and the inside of the shoe body 1 are connected to each other through the lead-out tube 13, so that the air inside the shoe body 1 is exchanged, thereby achieving the heat dissipation effect on the user's feet, keeping the user's feet dry, and improving the comfort of the user wearing the shoe body 1.

[0032] In this embodiment, the limiting assembly includes two guide columns 9 symmetrically fixedly installed on the outer surface of the movable cylinder 3 near its top end, and two L-shaped guide grooves 10 are opened in the circumferential direction of the inner wall of the mounting tube 2.

[0036] In this embodiment, a breathable cloth is sewn at the pipe opening of the extended end of the lead-out pipe 13, and the pipe opening of the lead-out pipe 13 is covered with the breathable cloth to prevent the pipe opening from being blocked by foreign matter such as dust and other impurities, thereby affecting the ventilation effect.

[0037] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the user can wear the shoe body 1 to perform labor work; when the foot is hot and sweaty, insert a finger into the toggle groove 15 and rotate the rubber pad 4, so that the rubber pad 4 drives the movable cylinder 3 to rotate, so that the guide column 9 installed on the movable cylinder 3 is toggled from the horizontal groove of the L-shaped guide groove 10 opened on the inner wall of the mounting tube 2 to the vertical groove, so that the compression spring 8 can push the movable cylinder 3 and the rubber pad 4 downward, so that the rubber pad 4 protrudes from the bottom of the sole 101, and the movable cylinder 3 and the rubber pad 4 are pressed downward. When the user steps on and walks, the rubber pad 4 can be continuously pressed up and down, so that the piston 5 installed in the movable cylinder 3 can make a piston movement in the piston cylinder 7, so that the piston cylinder 7 can continuously inhale or blow air into the inside of the shoe body 1 through the U-shaped tube 11 and the connecting tube 12, and the outside air and the inside of the shoe body 1 are mutually connected through the lead-out tube 13, so that the air inside the shoe body 1 is exchanged, thereby achieving the heat dissipation effect on the user's feet, keeping the user's feet dry, and improving the comfort of the user wearing the shoe body 1;

[0038] When there is no need to dissipate heat inside the shoe body 1, press and rotate the rubber pad 4 so that the guide column 9 installed on the movable cylinder 3 is again inserted into the horizontal groove of the L-shaped guide groove 10. The position of the mounting tube 2 can be limited by the guide column 9, so that the rubber pad 4 no longer protrudes from the bottom of the sole 101, and the shoe body 1 can be worn normally.
