A mounting hole is formed in a surface of the shell. The camera lens includes a body and a lens. One end of the body is disposed to the mounting hole, and the other end of the body extends out of the mounting hole. The lens is located at the other end of the body. The cover ring is connected to the body in a sleeving manner and fixed on the mounting hole. The outer cover is fixed at a periphery of the lens in a sleeving manner to form a first-layer waterproof structure and disposed on the surface of the shell, and covers the exterior of the cover ring. The cover ring abuts between the camera lens and the shell to form a second-layer waterproof structure. ## Claims ### Claim 1 A camera-lens waterproofing device, comprising: a shell, a mounting hole being formed in a surface of the shell; a camera lens, comprising a body and a lens, one end of the body being disposed in the mounting hole, and the other end of the body extending out of the mounting hole, and the lens being located at the other end of the body; and an outer cover, arranged at a periphery of the lens in a sleeving manner, disposed on the surface of the shell, wherein the outer cover comprises an outer layer and an inner layer, the inner layer is disposed on an inner side of the outer layer, and a thread fastened to a periphery of the camera lens is formed at one end of the inner layer. ### Claim 2 (depends on 1) The camera-lens waterproofing device according to claim 1, wherein an air vent is formed in the outer cover; a breathable film is attached to an inner side of the air vent; and a hollow ring slot is formed in the inner side of the outer cover. ### Claim 3 (depends on 2) The camera-lens waterproofing device according to claim 2, wherein an accommodating chamber is formed on the inner side of the outer cover corresponding to the shell and the body. ### Claim 4 (depends on 1) The camera-lens waterproofing device according to claim 1, wherein the inner side of the outer cover extends to form a rod piece; a through hole for allowing the rod piece to pass through is formed in the surface of the shell; and an end portion of the rod piece is thermally molten to an inner side surface of the shell. ### Claim 5 (depends on 1) The camera-lens waterproofing device according to claim 1, wherein a plurality of hooks is annularly arranged on the inner side of the outer cover, and a plurality of fastening slots rotatably fastened with the plurality of hooks is formed in the surface of the shell. ### Claim 6 (depends on 5) The camera-lens waterproofing device according to claim 5, wherein a groove is formed in an inner side of each hook; an inner side of each fastening slot extends to form an elastic arm; and a protruding block fastened to the groove is protruded from a side surface of the elastic arm. ### Claim 7 (depends on 1) The camera-lens waterproofing device according to claim 1, further comprising a cover ring, connected to the body in a sleeving manner and fixed on the mounting hole, the cover ring comprising an inner ring surface and an outer ring surface, the inner ring surface abutting against the body, the outer ring surface abutting against a wall surface of the mounting hole, and the outer cover covering an exterior of the cover ring and a broken opening is formed in the covering. ### Claim 8 (depends on 7) The camera-lens waterproofing device according to claim 7, wherein the cover ring comprises a ring body abutting against a surface of the camera lens, and an outer end portion forming on one end of the ring body and stuck to the surface of the shell. ### Claim 9 (depends on 8) The camera-lens waterproofing device according to claim 8, wherein the cover ring comprises an inner end portion forming on the other end of the ring body and stuck to an inner side surface of the shell. ### Claim 10 (depends on 7) The camera-lens waterproofing device according to claim 7, further comprising a plurality of sealing pieces, respectively attached between the shell and the outer cover, between the shell and the cover ring, or between the camera lens and the cover ring. ### Claim 11 (depends on 1) The camera-lens waterproofing device according to claim 1, further comprising at least one sealing piece, attached between the shell and the outer cover. ### Claim 12 (depends on 1) The camera-lens waterproofing device according to claim 1, further comprising a panel, attached to the surface of the shell.
