The invention discloses a dustproof fingerprint lock which comprises an outer door lock body, a cover board as well as a key panel and a fingerprint identification panel which are arranged on the outer door lock body, wherein two guide rails are arranged on the outer door lock body, two sides of the inner wall of the cover board are provided with grooves, each groove is composed of a straight section at the lower part and an expanding section at the upper part, the upper end of the straight section is connected with the lower end of the expanding section, the section of the expanding section is in an inverted trapezoid shape, and the guide rails and the grooves are matched to enable the cover board to be arranged on the guide rails in a sliding way and respectively cover the key panel and the fingerprint identification panel. After unlocking, the cover board is artificially pulled down or the cover board covers the key panel and the fingerprint identification panel again by virtue of the gravity of the cover board to ensure a dustproof effect on the key panel and the fingerprint identification panel; and when the cover board moves downward, the expanding section in each groove is directly fastened with the upper end of each guide rail, so that the cover board is prevented from directly sliding down from the guide rail, and meanwhile, over-large mutual displacement between the cover board and the guide rail can also be overcome when the cover board is pulled down artificially.
