Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to the front panel of an intelligent vein recognition door lock. Background Art

[0002] With the rapid development of society, people's homes are becoming more and more intelligent. Compared with traditional door locks, intelligent door locks can further confirm the identity characteristics of the unlocking personnel. At the same time, users do not need to carry keys with them when going out and can still open the door when they return, avoiding the embarrassing situation of being locked out of the door.

[0003] Existing intelligent door locks generally have finger vein unlocking. However, in a humid environment, a water vapor layer is likely to form on the finger vein recognition module, resulting in the failure of finger vein recognition. It often needs to be wiped with a dry absorbent such as a tissue before the finger vein recognition accuracy can be restored, and the use experience is not good. Summary of the Utility Model
