The invention discloses an informatization artificial-intelligence mailbox. The mailbox comprises an inserting seat arranged in a wall body and an inserting head fixedly arranged on the top of the mailbox through supporting columns, an inserting cavity corresponding to the inserting head is formed in the inserting seat, locking grooves are formed in the left and right parts of the inserting cavities, a conductive head is fixedly arranged on the inner top wall of the inserting cavity, a first sliding cavity is formed in the part above the inserting cavity, a first motor is fixedly arranged on the top of the first sliding cavity, the bottom of the first motor is dynamically and cooperatively connected with a first threaded rod, a first sliding plate is in threaded and cooperation connectionwith the first threaded rod, the first sliding plate and the first sliding cavity are slidably and cooperatively connected, and electrifying heads are symmetrically arranged on the bottom face of thefirst sliding plate on left and right. According to the mailbox, the structure is simple, the locking and pulling of the inserting heads are convenient and fast, electric conductivity is safe and stable, the number of letters which are put into the mailbox is counted by a counter, and the result is reflected on an electronic display screen.
