Problems solved by technology

[0003] When the fingerprint lock is in use, the user will leave fingerprint sweat stains on the fingerprint lock, and illegal personnel will extract fingerprints according to the sweat stains left by the user, and use this to open the fingerprint lock to steal, which makes the anti-theft performance of the fingerprint lock decline. When the user uses the password to unlock, it will also leave traces of use on the password keyboard, leaving an opportunity for the thief. Accordingly, the present invention proposes a fingerprint lock

specific Embodiment approach

[0025] As a specific embodiment of the present invention, the aperture value at the outlet of the water spray hole 12 is smaller than the aperture value at the bottom of the water spray hole 12. During work, there is a certain distance between the water spray hole 12 and the fingerprint collection place. Not enough, the cleaning liquid can’t reach the fingerprint identification module 1b, that is, it can’t have the cleaning effect, and the diameter of the outlet of the water spray hole 12 becomes smaller, which increases the pressure of the cleaning liquid at the outlet of the water spray hole 12, so that the cleaning liquid can pass through the spray hole 12. When the water hole 12, the flow rate is increased, the spray is farther, and the cleaning rate is improved. On the one hand, it can spray farther to reach the fingerprint recognition module 1b. On the other hand, the impact force of the cleaning liquid is used to wash away the sweat stains , so that the sweat stains on t...
