Fingerprint module and intelligent door lock

Abstract

According to the fingerprint module and the intelligent door lock, a fingerprint upper cover with a fingerprint recognition assembly is pressed on a lock body shell through a fingerprint pressing plate, and the fingerprint recognition assembly is contained in a first sealing cavity defined by a side surrounding body of the fingerprint upper cover and the fingerprint pressing plate; the sealing material filled in the first sealing cavity can isolate communication between the window and the first sealing cavity, and a gap between the fingerprint identification assembly and the fingerprint upper cover is completely sealed, so that even if water vapor outside the door lock enters the door lock, the existence of the sealing material can also prevent the water vapor from being in contact with electronic elements and circuits of the fingerprint identification assembly, and the safety of the door lock is improved. Therefore, the whole fingerprint module can work normally.
