Technical Field

[0001] This utility model relates to the field of fingerprint lock technology for video intercom hosts, and more particularly to fingerprint locks for video intercom hosts. Background Technology

[0002] The video intercom fingerprint lock is a smart lock that integrates video surveillance, voice communication and access control functions. Its main functions include remote video intercom, real-time video monitoring, electronic doorbell and remote unlocking.

[0003] Existing video intercom host fingerprint locks are all exposed to the outside. Prolonged contact with air or during use will cause dust and impurities to accumulate on the display screen and camera surface, making it difficult to observe visually. This requires manual cleaning, which is a complicated process and may not be thorough enough, easily affecting the observation of the outside situation by the people inside, making it impractical.

[0004] Therefore, existing video intercom host fingerprint locks are exposed to the outside, and prolonged contact with air or use can cause dust and impurities to accumulate on the display screen and camera surface, making visual observation difficult and requiring manual cleaning. This process is complex and often not thorough, easily affecting the internal personnel's observation of the outside situation, thus making it impractical. To address this issue, an automated device for cleaning the display screen can be designed, greatly improving practicality, providing a more thorough cleaning, and facilitating the internal personnel's observation of the external situation. Utility Model Content

[0014] The beneficial effects of this utility model are:

[0015] When cleaning the display screen surface, the cleaning device allows cleaning agent to be added through the cleaning agent suction port at the rear end. The internal sponge suction block absorbs the cleaning agent. By moving the connecting rod to one end, the gears on the outside engage with the toothed grooves on both sides, moving the sponge suction block to the front. Through compression, the cleaning agent overflows from the stain removal block at the front end of the sponge suction block. The operation of the lead screw inside the connecting blocks on both sides causes the first slider to move the cleaning device up and down, while the stain removal block contacts the display screen surface to clean the stains, ensuring the cleanliness of the display screen surface. This automated display screen cleaning mechanism greatly improves practicality, provides a more thorough cleaning, and facilitates the observation of the external situation by personnel inside.
