[0026] Embodiment 1:

[0027] The fingerprint recognition elevator button provided by the utility model is preferably implemented as follows Figures 1 to 6 As shown: a fingerprint recognition elevator button, including a fingerprint recognition lock 1, a pressing plate 3, a protective frame 2 is fixedly installed on the top of the fingerprint recognition lock 1, the pressing plate 3 is clamped in the protective frame 2, a fingerprint recognition screen 9 is fixedly installed on the top of the fingerprint recognition lock 1, a slider 5 is fixedly installed on the outer wall of the pressing plate 3, a slide groove 8 is provided on the inner wall of the protective frame 2, the slider 5 is slidably connected with the slide groove 8, a limit rod 6 is fixedly installed on the inner wall of the slide groove 8, the limit rod 6 movably penetrates the slider 5, a spring 7 is surrounded on the outer wall of the limit rod 6, the spring 7 is fixedly installed between the bottom end of the slider 5 and the bottom end of the inner wall of the slide groove 8, and a protective cleaning mechanism 4 is provided at the bottom end of the pressing plate 3;

[0028] The protective cleaning mechanism 4 includes a folding frame 401, a baffle 402 and a fixed bar 405. The top of the folding frame 401 is hinged to the bottom of the pressure plate 3. A slider 407 is fixedly installed at the bottom of the fixed bar 405. A slide groove 409 is provided at the top of the fingerprint recognition lock 1. The slider 407 is slidably connected to the slide groove 409. A limit rod 408 is fixedly installed on the inner wall of the slide groove 409. The limit rod 408 movably penetrates the slider 407. A spring 404 is surrounded on the outer wall of the limit rod 408. The spring 404 is fixedly installed between one side of the slider 407 and the inner wall of the slide groove 409. A slot 406 is provided at the top of the fixed bar 405. The baffle 402 is clamped in the slot 406. A cleaning cloth 403 is fixedly installed at the bottom of the baffle 402. The bottom end of the folding frame 401 and one end of the fixed bar 405 are slidably connected to the top surface of the fingerprint recognition lock 1.

[0029] Specifically, the above technical solution is as follows: insert the finger into the finger placement hole 12, and then press the pressure plate 3 downward. The pressure plate 3 drives the folding frame 401 to rotate, so that the folding frame 401 pushes the fixing bar 405 to move to the left, and the fixing bar 405 drives the baffle 402 to move. The baffle 402 drives the cleaning cloth 403 to move to the left, so that the cleaning cloth 403 cleans the dust or grease that may be attached to the surface of the fingerprint recognition screen 9. When the baffle 402 is completely removed from the fingerprint recognition screen 9, the finger can just contact the fingerprint recognition screen 9 to perform fingerprint recognition unlocking. Through this mechanism, when performing fingerprint recognition unlocking, the dust or grease that may be attached to the fingerprint recognition screen 9 during previous use can be cleaned to prevent dust or grease from affecting the fingerprint recognition accuracy. This solves the problem that the existing technical solution does not have a structure for cleaning the fingerprint recognition screen 9 when protecting it, resulting in the fingerprint recognition screen 9 being attached with some dust or grease after long-term use, thereby affecting the fingerprint recognition accuracy.

[0030] Further, the cleaning cloth 403 is in contact with the surface of the fingerprint recognition screen 9, and the number of the fixing strips 405 is two;

[0031] Wherein, by providing the cleaning cloth 403, dust or grease that may be attached to the fingerprint recognition screen 9 can be cleaned.

[0032] Furthermore, the number of the slider 1 5 and the number of the slide groove 1 8 are both four, and the slider 1 5 and the slide groove 1 8 are adapted;

[0033] Among them, by setting a slider 5, the pressure plate 3 can be limited to improve the stability of the pressure plate 3 on the protective frame 2.

[0034] Furthermore, the second slide block 407 is matched with the second slide groove 409, and a finger placement hole 12 is provided on the pressing plate 3;

[0035] Among them, by setting the slider 2 407 , the fixing bar 405 can be limited, so that the fixing bar 405 can achieve fixed sliding on the fingerprint recognition lock 1 .

[0036] Embodiment 2:
