Safety protection intelligent door lock for smart home

Abstract

The invention relates to the technical field of door locks, in particular to a safety protection intelligent door lock for a smart home. The door lock comprises a lock body, a fingerprint identifier main body, a cleaning mechanism, a driving mechanism and a control mechanism; an operation surface of fingerprint identification can be embedded into the lock body, so that the dustproof and waterproofprotection for a fingerprint identification probe is realized; when a finger of a user has water, the finger can be dragged obliquely and downwards along a sponge column, so that the water on the finger is absorbed by a top area of the sponge column; when the sponge column rotates around an installation plate, a bottom area of the sponge column also rotates, the water on the fingerprint identification probe is absorbed away and dust is wiped off, so that synchronous cleaning of the finger and the probe is realized, and the finger can be rapidly wiped to be dry and the fingerprint identification is performed under the condition that the finger has the water; and the cleaning mechanism can be quickly reset under the pushing of a spring, so that daily operation is not affected.
