[0020] 1. By providing a control mechanism, a control frame, and a baffle connection mechanism, the present invention can increase the air circulation in the sole, help reduce the temperature of the sole of the foot, relieve discomfort caused by high temperature or long-term standing. In addition, this design also allows patients to adjust the ventilation degree according to personal comfort, and can achieve immediate adjustment of the shoe interior environment through simple mechanical operations. This design not only improves the wearing experience of diabetic foot patients, but also effectively prevents complications caused by overheating of the feet. Specifically, when the patient's sole sweats after being in hot weather or staying for a long time, the dual-axis motor can be activated. The motor rotates the lead screw, pushing the transmission block and the push rod, causing the cross bar to move inward. The rotating rod then rotates, driving the baffle to unfold, exposing the ventilation slots. At the same time, the rack bar slides within the chute plate, engaging the gear to rotate, causing the rotary handle and the rotating rod to rotate, opening the ventilation structure of the sole air pipe.

[0021] 2. By providing a sole air pipe and an air pipe expansion and contraction mechanism, diabetic foot patients can adjust the ventilation volume inside the shoe according to actual needs through simple operations, thereby achieving the purpose of adjusting the temperature inside the shoe, greatly improving the comfort and safety of wearing. Specifically, when the rotating rod rotates, it drives the expansion and contraction control lead screw to rotate, and then causes the columnar transmission rod to move along the axial direction of the lead screw. This movement pushes the columnar push rod and the transmission shaft to slide on the outer wall of the lead screw through the push and pull disc, resulting in the rotation of the rotating rod on the outer wall of the fixed shaft and the rotating rod on the outer wall of the transmission shaft, realizing the expansion and contraction of the expansion and contraction plate and the air pipe. This enables the air pipe to extend out of the outer wall of the air pipe retaining frame, no longer being blocked, and starts to ventilate the inner wall of the sole, while increasing the ventilation area of the sole air pipe.

On the inner sides of the left and right groups of vertical connecting rods 314, chute plate connection blocks 315 are fixedly connected. On the inner sides of the two chute plate connection blocks 315, chute plates 316 are fixedly connected. Rack rods 318 are slidably connected to the inner walls of the two chute plates 316. Gears 319 are rotatably connected to the middle of the bottoms of the two chute plates 316. On the front and back sides of the two gears 319, turning handles 3110 are fixedly connected. On the outer sides of the two groups of turning handles 3110, rotating rods 3111 are fixedly connected. On the sides of the two chute plates 316 away from the chute plate connection blocks 315 at the top, two C-shaped chute plate connection blocks 3112 are fixedly connected. On the tops of the left and right groups of C-shaped chute plate connection blocks 3112, C-shaped chute plates 3113 are fixedly connected. On the inner sides of the two sides of the two C-shaped chute plates 3113 close to each other, chute blocks 3114 are fixedly connected. On the front and back sides of the two C-shaped chute plates 3113 and on the sides aligned with the two groups of chute blocks 3114, expansion and contraction rod chutes 3115 are provided. A dual-axis motor 313 is fixedly connected to the top of the inverted U-shaped connecting plate 312. Screw rods 317 are fixedly connected to the output ends on the left and right sides of the dual-axis motor 313. The ends of the two screw rods 317 away from the dual-axis motor 313 are respectively movably connected to the inner sides of the two chute plate connection blocks 315. The two baffle connection mechanisms 32 each include a transmission block 321. The inner walls of the two transmission blocks 321 are respectively threadedly connected to the outer walls of the two screw rods 317. The bottoms of the two transmission blocks 321 are respectively fixedly connected to the tops of the two rack rods 318. Push rods 322 are fixedly connected to the inner sides of the two transmission blocks 321. The ends of the two push rods 322 away from the transmission blocks 321 respectively extend into the inner sides of the two C-shaped chute plates 3113 and are both fixedly connected to cross bars 323. On the front and back sides of the tops of the two cross bars 323, rotating rods 324 are rotatably connected. On the bottom sides of the two groups of rotating rods 324 away from the cross bars 323, expansion and contraction rods 325 are rotatably connected. The outer sides of the two groups of expansion and contraction rods 325 are slidably connected to the inner walls of the expansion and contraction rod chutes 3115. The inner sides of the two groups of expansion and contraction rods 325 are slidably connected to the inner walls of the chute blocks 3114. L-shaped baffle connection blocks 326 are fixedly connected to the inner sides of the two groups of expansion and contraction rods 325. Baffles 327 are fixedly connected to the sides of the two groups of L-shaped baffle connection blocks 326 away from the expansion and contraction rods 325. The tops of the two groups of baffles 327 are attached to the side of the bottom of the arch pad 22 aligned with the ventilation groove 23;

[0036] When the patient feels that the soles of the feet are gradually sweating in hot weather or after staying in a certain place for too long, at this time, the patient controls the start of the biaxial motor 313. The biaxial motor 313 starts to drive the lead screws 317 at both ends to rotate. The rotation of the lead screws 317 at both ends drives the two transmission blocks 321 to move inward. The inward movement of the two transmission blocks 321 pushes the push rod 322 to push the cross bar 323 inside the biaxial motor 313 to move. When the two cross bars 323 move inward, the two rotating rods 324 on the tops of the two cross bars 323 rotate, and then the two sets of expansion and contraction rods 325 pull the two sets of baffles 327 to expand outward, so that the baffles 327 unfold and no longer block the ventilation slots 23 opened in the arch pad 22;

[0037] At the same time, when the two transmission blocks 321 move inward, they drive the two rack bars 318 to slide on the inner wall of the chute plate 316 at the same time, and then engage the two gears 319 to rotate. The rotation of the two gears 319 drives the two sets of handles 3110 and the rotating rod 3111 to rotate. The rotation of the rotating rod 3111 unfolds the inside of the plantar air pipe 4, and the ventilation structure inside the plantar air pipe 4 is opened, increasing air circulation, helping to reduce the temperature of the soles of the feet, and relieving discomfort caused by high temperature or long-term standing. In addition, this design also allows the patient to adjust the ventilation degree according to personal comfort, and the immediate adjustment of the shoe inner environment can be realized through simple mechanical operations. This design not only improves the wearing experience of diabetic foot patients, but also effectively prevents complications caused by overheating of the feet, providing a safer and more comfortable wearing option for diabetic foot patients.

[0038] Such as Figures 5-7As shown, the plantar ventilation pipe 4 includes an outer pipe 41. An inner wall of one end of the outer pipe 41 away from the sole body 21 is fixedly connected with a dust-proof net 42. An inner pipe 43 is fixedly connected to the inner wall of the outer pipe 41. An air pipe expansion and contraction mechanism 46 is movably connected to the inner wall of the inner pipe 43. Inner pipe grooves 44 are formed in an annular array on the outer wall of the inner pipe 43. Air pipe blocking frames 45 are fixedly connected in an annular array on one side of the outer wall of the inner pipe 43 aligned with the formed inner pipe grooves 44. The air pipe expansion and contraction mechanism 46 includes a screw rod connecting column 461. One end of the screw rod connecting column 461 is fixedly connected to the inner wall of the inner pipe 43. An expansion and contraction control screw rod 4610 is rotatably connected to one side of the screw rod connecting column 461. A fixed shaft 462 is fixedly connected to one side of the outer wall of the screw rod connecting column 461. A transmission shaft 463 is slidably connected to one side of the outer wall of the expansion and contraction control screw rod 4610 away from the fixed shaft 462. Rotating rods 464 are rotatably connected to the outer walls of the transmission shaft 463 and the fixed shaft 462 in an annular array. Expansion and contraction plates 468 are rotatably connected to one side of multiple groups of rotating rods 464 away from the transmission shaft 463 and the fixed shaft 462. Air pipes 469 are fixedly connected to the outer sides of multiple expansion and contraction plates 468. The outer sides of multiple expansion and contraction plates 468 and the air pipes 469 are aligned with the inner pipe grooves 44 formed in the inner pipe 43 and are movably connected to the inner sides of multiple air pipe blocking frames 45. Columnar push rods 465 are fixedly connected in an annular array on one side of the transmission shaft 463 away from the fixed shaft 462. A push-pull disk 466 is fixedly connected to one end of multiple columnar push rods 465 away from the transmission shaft 463. A columnar transmission rod 467 is fixedly connected to the inner wall of the push-pull disk 466. The inner wall of the columnar transmission rod 467 is threadedly connected to the outer wall of the expansion and contraction control screw rod 4610 away from the transmission shaft 463. One end of the expansion and contraction control screw rod 4610 away from the inner wall of the inner pipe 43 is fixedly connected to one side of the rotating rod 3111 away from the handle 3110;

[0039] While the two groups of rotating rods 3111 are rotating, they drive the expansion and contraction control lead screw 4610 to rotate. Due to the threaded connection between the expansion and contraction control lead screw 4610 and the columnar transmission rod 467, when the expansion and contraction control lead screw 4610 rotates, it drives the columnar transmission rod 467 to axially move on the outer wall of the expansion and contraction control lead screw 4610. Thus, the columnar push rod 465 is pushed by the push and pull plate 466 to slide on the outer wall of the expansion and contraction control lead screw 4610 together with the transmission shaft 463. While the transmission shaft 463 is sliding on the outer wall of the expansion and contraction control lead screw 4610, the rotating rod 464 on the outer wall of the fixed shaft 462 and the rotating rod 464 on the outer wall of the transmission shaft 463 rotate, thereby realizing the expansion and contraction of the expansion and contraction plate 468 and the air pipe 469. The air pipe 469 extends out of the outer wall of the air pipe retaining frame 45 and is no longer blocked by the air pipe retaining frame 45, thus starting to ventilate the inner wall of the sole 2. Moreover, the expansion and contraction of the air pipe 469 increases the ventilation area of the plantar ventilation pipe 4, further enhancing air circulation, effectively reducing the temperature inside the shoe, and providing a cooler and more comfortable wearing environment for diabetic foot patients. Through this design, diabetic foot patients can adjust the ventilation volume inside the shoe according to actual needs through simple operations, thereby achieving the purpose of adjusting the temperature inside the shoe, greatly improving the comfort and safety of wearing.

[0040] Working principle of the present invention: When the patient feels that the soles of the feet are gradually sweating in hot weather or after staying somewhere for too long, at this time, the patient controls and starts the double-shaft motor 313. The double-shaft motor 313 starts to drive the lead screws 317 at both ends to rotate. The lead screws 317 at both ends rotate to drive the two transmission blocks 321 to move inward. The two transmission blocks 321 move inward to push the push rod 322 to push the cross bar 323 inside the double-shaft motor 313 to move. While the two cross bars 323 are moving inward, the two rotating rods 324 on the tops of the two cross bars 323 rotate, and then the two groups of expansion and contraction rods 325 pull the two groups of baffles 327 to expand outward, so that the baffles 327 are unfolded and no longer block the ventilation slots 23 opened in the arch pad 22. At the same time, while the two transmission blocks 321 are moving inward, they drive the two rack bars 318 to slide on the inner wall of the chute plate 316 at the same time, and then engage the two gears 319 to rotate. The two gears 319 rotate to drive the two groups of turning handles 3110 and the rotating rods 3111 to rotate. Through the rotation of the rotating rod 3111, the inside of the plantar ventilation pipe 4 is unfolded, and the ventilation structure inside the plantar ventilation pipe 4 is opened to increase air circulation and help reduce the temperature of the soles of the feet;

[0041] While the two groups of rotating rods 3111 are rotating, they drive the expansion and contraction control lead screw 4610 to rotate. Due to the threaded connection between the expansion and contraction control lead screw 4610 and the columnar transmission rod 467, when the expansion and contraction control lead screw 4610 rotates, it drives the columnar transmission rod 467 to axially move on the outer wall of the expansion and contraction control lead screw 4610. Thus, the columnar push rod 465 is pushed by the push and pull disc 466 to slide on the outer wall of the expansion and contraction control lead screw 4610 together with the transmission shaft 463. While the transmission shaft 463 is sliding on the outer wall of the expansion and contraction control lead screw 4610, the rotating rod 464 on the outer wall of the fixed shaft 462 and the rotating rod 464 on the outer wall of the transmission shaft 463 rotate, thereby realizing the expansion and contraction of the expansion and contraction plate 468 and the air pipe 469, so that the air pipe 469 extends out of the outer wall of the air pipe retaining frame 45 and is no longer blocked by the air pipe retaining frame 45, thus starting to ventilate the inner wall of the sole 2. Moreover, the expansion and contraction of the air pipe 469 increases the ventilation area of the sole ventilation pipe 4, further enhancing the air circulation.
