Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] Please see the attached Figure 1 - Attachment Figure 5A wearable biosensor includes a sensor body 1 and a mounting and disassembly mechanism 4, wherein the mounting and disassembly mechanism 4 includes a snap ring 401, a slot base 403, and a limiter 408. A snap 402 is fixedly connected to the bottom of the outer wall of the snap ring 401, a slot cover 404 is fixedly connected to the outer wall of the slot base 403, and a limiter 405 is fixedly connected to the upper surface thereof, and is fixedly connected to the bottom of the outer wall of the sensor body 1. The upper surface of the limiter 405 is fixedly connected to the slot cover 404, the upper surface of the limiter 408 is fixedly connected to the slot cover 404, and the lower surface thereof does not contact the slot base 403. The upper surface of the sensor body 1 is mounted There is a protective film 2, and a connecting belt 3 is sleeved on its outer wall. A first reserved button hole 406 is provided on the side wall of the slot cover 404, and a reserved slot 407 is provided on its upper surface. A first limit button 409 is inserted into the inner wall of the first reserved button hole 406. The first limit button 409 is fixedly connected to the first spring 410 at one end away from the first reserved button hole 406, and its two sides are against the limit member 408, and its lower surface does not contact the slot base 403. The lower surfaces of the snap ring 401 and the buckle 402 are against the upper surface of the slot base 403, and the end of the first spring 410 away from the first limit button 409 is against the outer wall of the snap ring 401.

[0025] The space between the first limit button 409 and the limit block 405 just accommodates the buckle 402 for the purpose of fixing. The distance between the lower surface of the first limit button 409 and the limit member 408 and the upper surface of the slot base 403 is slightly larger than the thickness of the buckle 402 close to the snap ring 401, and much smaller than the thickness of the buckle 402 away from the snap ring 401. The end of the buckle 402 away from the snap ring 401 does not collide with the limit member 408 during the rotation process, so that after pressing the first limit button 409, the buckle 402 can be smoothly rotated to abut against the limit block 405. The installation and disassembly mechanism 4 can be used to easily replace the connecting belts 3 of different materials and the adjustment mechanisms 5 fixedly connected on both sides thereof. For example, the connecting belts 3 and adjustment mechanisms 5 of warm-keeping materials are used in winter, and the connecting belts 3 and adjustment mechanisms 5 of breathable materials are used in summer, thereby increasing the user's comfort.

[0026] Specifically, the retaining ring 401 and the buckle 402 can be smoothly inserted into the slot cover 404 through the reserved slot 407, and rotate in the space between the slot cover 404 and the slot base 403. The first reserved button hole 406 and the limit member 408 can limit the first limit button 409 to slide only along a specific horizontal direction. The rotation channel of the buckle 402 can be opened by pressing the first limit button 409 and the first spring 410. When the buckle 402 rotates counterclockwise through the first limit button 409 and abuts against the limit block 405, the first limit button 409 is loosened so that it and the limit block 405 can jointly fix the position of the buckle 402, so that the sensor body 1 can be conveniently and quickly installed on the connecting belt 3. The sensor body 1 can be quickly removed from the connecting belt 3 by the reverse steps.

[0027] Example 2:

[0028] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 and attached Figure 7 , and on the basis of Example 1, it is further obtained that an adjustment mechanism 5 is provided at both ends of the connecting belt 3, and the adjustment mechanism 5 includes a rack 501, a fixed base 503, a reserved groove 505 and a fixed shaft 506. The rack 501 is fixedly connected to the end of the connecting belt 3 close to the snap ring 401, and a tooth groove 502 is provided on one side of the rack 501. The fixed base 503 is fixedly connected to the end of the connecting belt 3 away from the snap ring 401, and a cover plate 504 is fixedly connected to the upper surface near the two ends. The reserved groove 505 is provided on the upper surface of the fixed base 503, and the fixed shaft 506 is fixed to the fixed base 503 and the cover plate 504. The bottom surface of the reserved groove 505 is fixedly connected with a second spring 508, and the end of the second spring 508 away from the reserved groove 505 is fixedly connected with a second limit button 509. The upper surface of the cover plate 504 and the upper part of the second limit button 509 are at the same axial position. A second reserved button hole 507 is provided, and the upper part of the second limit button 509 is inserted into the inner wall of the second reserved button hole 507. The outer wall of the fixed shaft 506 is rotatably connected with a driven gear plate 510, and the driven gear plate 510 can engage with the tooth groove 502. The lower part of the second limit button 509 is inserted into the outer wall of the driven gear plate 510.

[0029] Since the teeth 502 on the rack 501 are evenly distributed, more precise length adjustment can be achieved to ensure wearing comfort and fit. The engagement between the driven gear plate 510 and the teeth 502 on the rack 501 can provide a strong fixing force, which is not easy to loosen or slide during exercise, ensuring good contact between the sensor and the skin and facilitating the sensor's collection work.

[0030] Specifically, the movement of the driven gear plate 510 can be limited by the fixed shaft 506 set at an appropriate position, and the driven gear plate 510 can be engaged with the tooth groove 502 on the rack 501. By pressing or releasing the second limit button 509 and the second spring 508, the rotation restriction of the driven gear plate 510 can be released or restored. When the second limit button 509 is pressed and the rack 501 is inserted between the fixed base 503 and the cover plate 504, the rack 501 can be inserted or pulled out through the engagement of the tooth groove 502 with the driven gear plate 510 and the rotation of the driven gear plate 510 to adjust the length of the wearable part. After adjusting to the appropriate length, release the second limit button 509 to limit the rotation of the driven gear plate 510 to fix the adjusted length, thereby achieving the purpose of quickly fitting the wearable part to the skin of users of different body shapes.

When using the wearable biosensor, insert the snap ring 401 and the buckle 402 into the reserved slot 407, press the first limit button 409 through the first spring 410, and rotate the buckle 402 counterclockwise until it contacts the limit block 405. Release the first limit button 409, and the first limit button 409 returns to its original position under the rebound action of the first spring 410, so that it fixes the position of the buckle 402 together with the limit block 405, completing the installation of the sensor body 1 and the connecting belt 3. Insert the rack 501 into the fixed base 503 and the cover 50 4, and at the same time, the second limit button 509 is pressed by the second spring 508 to release the rotation restriction of the driven gear plate 510. The tooth groove 502 is engaged with the driven gear plate 510 and the driven gear plate 510 is rotated to insert the rack 501 to a position suitable for the user's body shape. The second limit button 509 is released and returns to its original position under the rebound action of the second spring 508, restoring the rotation restriction of the driven gear plate 510, so that the sensor body 1 can be stably and closely fitted to the user's skin. After use, the wearable sensor can be removed in the same way and the sensor body 1 can be removed from the connecting belt 3.
