The outer wall of the anti-slip rotating sleeve 2202 is rotatably connected to the inner wall of the drive groove 216.

[0024] like Figure 6 As shown, the fixing component 23 includes an arc-shaped plate 231. The outer wall of the arc-shaped plate 231 is fixedly connected to the inner wall of the arc groove clamping plate 221. The inner wall of the arc-shaped plate 231 has a plurality of mounting grooves 232 arranged in a ring array. Mounting grooves 233 are provided on both the front and rear sides of the inner wall of the mounting grooves 232.

[0025] like Figure 7 As shown, the adaptive component 24 includes a mounting groove 241. The outer wall of the mounting groove 241 is slidably connected to the inner wall of the second mounting groove 232. A stimulation electrode 242 is fixedly connected to the outer end face of the mounting groove 241. Sliding sleeves 243 are fixedly connected to both the front and rear sides of the mounting groove 241. A sliding rod 244 is slidably connected to the inner wall of the sliding sleeve 243. A spring 245 is sleeved on the outer wall of the inner end of the sliding rod 244. The outer wall of the sliding sleeve 243 is slidably connected to the inner wall of the third mounting groove 233. The left and right ends of the sliding rod 244 are fixedly connected to the inner walls of the left and right sides of the third mounting groove 233, respectively.

[0026] like Figure 8As shown, the adaptive structure 3 includes a fixed sleeve 31. The outer wall of the fixed sleeve 31 is fixedly connected to the inner wall of the upper mounting through hole 14. A limit rod 32 is slidably connected to the inner wall of the fixed sleeve 31. A spring 33 is sleeved on the bottom of the outer wall of the limit rod 32. A collection electrode 34 is fixedly connected to the bottom of the limit rod 32. The two ends of the spring 33 are respectively connected to the bottom of the fixed sleeve 31 and the top of the collection electrode 34.

[0027] When using this invention, by placing the cap 11 into the patient's head, the fixing sleeve 31 will be squeezed, causing the limiting rod 32 to move upward within the fixing sleeve 31. At the same time, the spring 33 is compressed, and the acquisition electrode 34 adjusts its position to fit the patient's scalp. It can automatically adjust according to the shape and size of the patient's head to ensure good contact between the acquisition electrode 34 and the scalp, thereby improving the accuracy and stability of signal acquisition. Furthermore, after the cap 11 is worn, rotating the anti-slip sleeve 2202 drives the fixing rod 2201 to rotate, which in turn drives the conical teeth 220 at both ends to rotate, causing the conical teeth 229 to rotate. The rotation of the conical teeth 229 drives the connecting shaft 228 to rotate the rotating rod 226 inside the support sleeve 227. The rotation of the rotating rod 226 drives the two conical teeth 224 to rotate, causing the conical tooth sleeve 225 to rotate, and driving the meshing conical tooth sleeve 225 to rotate, thereby driving the lead screw 223 to rotate in the mounting groove 213. The rotation of the lead screw 223 drives the slider 222 to move on the outer wall of the lead screw 223, thereby causing the arc groove clamps 221 on the left and right sides to move closer or further apart, which can adapt to the size of different patients' heads and firmly fix the rehabilitation cap in the appropriate position, avoiding the treatment effect due to the cap loosening. Meanwhile, the stimulation electrode 242 inside the arc plate 231 will automatically adjust its position according to the scalp. By contacting the scalp with the stimulation electrode 242, the mounting groove 241 will move on the inner wall of the mounting groove 232. The mounting groove 241 will then drive the sliding sleeve 243 to slide on the sliding rod 244, and the spring 245 will be compressed accordingly. This ensures that the stimulation electrode 242 can fit tightly against the scalp surface, which not only improves the contact quality between the electrode and the scalp, but also further enhances the precision of the treatment.

[0028] like Figure 9As shown, the filter structure 4 includes a mounting frame 41. A limiting component 42 is provided on the top of the mounting frame 41. A fan 43 is provided inside the mounting frame 41. The outer wall of the mounting frame 41 is fixedly connected to the inner wall of the mounting through hole 14 on the lower side. A heating element 44 is provided inside the mounting frame 41 near the right side of the fan 43. A fixing plate 45 is provided inside the mounting frame 41 near the right side of the heating element 44. A slot 46 is provided on the top of the fixing plate 45. A rectangular through hole 47 is provided on the top of the mounting frame 41, penetrating into the slot 46. Rectangular through holes 48 are provided on both the left and right sides of the inner wall of the slot 46, penetrating to the outside. An insert frame 49 is slidably connected to the inner wall of the slot 46 and the rectangular through hole 47. A limiting groove 40 is provided on the right side of the insert frame 49. A sponge 401 is detachably connected to the inner wall of the limiting groove 40. A U-shaped handle 402 is fixedly connected to the top outer wall of the insert frame 49. Filter screens 403 are fixedly connected to both the left and right sides of the inner wall of the mounting frame 41.

[0029] like Figure 10 As shown, the limiting component 42 includes a limiting plate 421. The bottom of the limiting plate 421 is slidably connected to the top of the insert frame 49 and the mounting frame 41. Sliding sleeves 422 are fixedly connected to both the front and rear sides of the limiting plate 421. A sliding rod 423 is slidably connected to the inner wall of the sliding sleeve 422. A spring 424 is sleeved on the right side of the outer wall of the sliding rod 423. Fixing blocks 425 are fixedly connected to both the left and right ends of the sliding rod 423. The bottom of the fixing block 425 is fixedly connected to the top of the mounting frame 41. A pull hole 426 extending through to the bottom is provided on the top right side of the limiting plate 421.

[0030] When this invention is in use, the operation of the fan 43 draws air into the mounting frame 41. After initial filtration by the filter screen 403, the air enters the sponge 401 inside the insert frame 49 to remove impurities. Subsequently, the air passes through the heating element 44, which moderately heats it to a suitable temperature. The air then continues to flow into the interior of the mounting cap 11, providing a more comfortable user experience for the patient. When the temperature and humidity sensor inside the rehabilitation cap 1 detects that the ambient temperature and humidity exceed the preset range, the heating element 44 will be activated or deactivated as needed to adjust the temperature inside the cap and ensure the patient's comfort while wearing it. When the sponge 401 needs to be replaced or cleaned, the limiting plate 421 is moved by pulling the pull hole 426, which in turn causes the sliding sleeve 422 to slide on the sliding rod 423. At the same time, the spring 424 is compressed, and the limiting plate 421 gradually disengages from the top of the insert frame 49, releasing the lock on the insert frame 49. Then, the insert frame 49 is pulled out from the rectangular through hole 47 through the handle 402, making it easy to replace or clean the sponge 401. After replacement, the insert frame 49 is reinserted into the slot 46, and the pull hole 426 is released. The spring 424 rebounds and pushes the limiting plate 421 back into the inside of the handle 402, relocking the insert frame 49 and ensuring its stable installation. This not only facilitates daily maintenance but also effectively ensures the continuity of the filtration effect, further improving the user experience and treatment effect of the rehabilitation headgear.

[0031] Working principle of this invention: In use, by inserting the cap 11 into the patient's head, the fixing sleeve 31 will be squeezed, causing the limiting rod 32 to move upward within the fixing sleeve 31. At the same time, the spring 33 is compressed, and the acquisition electrode 34 adjusts its position to fit the patient's scalp. It can automatically adjust according to the shape and size of the patient's head to ensure good contact between the acquisition electrode 34 and the scalp, thereby improving the accuracy and stability of signal acquisition. After the cap body 11 is worn, rotating the anti-slip sleeve 2202 drives the fixing rod 2201 to rotate. The rotation of the fixing rod 2201, via the transmission of the conical teeth 220 and 229, drives the connecting shaft 228 to rotate, causing the rotating rod 226 to rotate inside the support sleeve 227. The rotation of the rotating rod 226, via the transmission of the conical teeth 224 and 225, drives the lead screw 223 to rotate within the mounting groove 213. Due to the thread between the slider 222 and the lead screw 223... The connection allows the slider 222 to move within the mounting slot 213, thereby causing the arc-shaped clamps 221 on the front and rear sides to move closer or further apart, adapting to different patient head sizes and firmly fixing the rehabilitation headgear in the appropriate position, preventing the treatment effect from being affected by the headgear loosening; at the same time, the stimulation electrode 242 inside the arc-shaped plate 231 will automatically adjust its position according to the scalp, ensuring that the stimulation electrode 242 can closely fit the scalp surface, which not only improves the contact quality between the electrode and the scalp, but also further enhances the precision of the treatment; Furthermore, through the operation of the fan 43, air is introduced into the mounting frame 41, and after being initially filtered by the filter screen 403, it enters the sponge 401 in the insert frame 49 to remove impurities from the air. Then, it passes through the area of ​​the heating element 44, where the heating element 44 moderately heats the air to a suitable temperature. The air then continues to flow into the interior of the mounting cap 11, providing patients with a more comfortable user experience. When the temperature and humidity sensor inside the rehabilitation head cap 1 detects that the ambient temperature and humidity exceed the preset range, the heating element 44 will be turned on or off as needed to adjust the temperature inside the head cap and ensure the patient's comfort when wearing it.
