The skilled in the art can make some non-essential improvements and adjustments to the present application according to the content of the above application; based on the embodiments in the present application, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the present application.

[0024] Please refer to Figures 1-3 A mothproof and waterproof printer device, comprising a main shell 1, a base 2, a main board 3 and a waterproof cover 4, the main shell 1 and the base 2 are connected together, the upper end of the main shell 1 is provided with a movable cover plate 12 and an operation panel 13, the base 2, the main shell 1, the movable cover plate 12 and the operation panel 13 constitute a relatively closed printer outer shell; the waterproof cover 4 is arranged in the middle of the inside of the base 1 and the main shell 2, and the main board 3 is fixed in the inside of the waterproof cover 4. The inside of the main shell 1 is provided with a printing mechanism 14, and the printing mechanism 14 is located above the waterproof cover 4; the side of the printing mechanism 14 is provided with a paper roll 15.

[0025] The movable cover plate 12 is rotatably installed on the main shell 1, so that one end of the movable cover plate 12 can be flipped along the main shell 1.

[0026] The base 2 and the main shell 1 are connected together through screws, the inside of the main shell 1 is provided with a plurality of screw hole columns 17 for connection, the base 2 is provided with a plurality of first connecting columns 16 corresponding to the screw hole columns 17, the first connecting columns 16 can be inserted with screws, and the screw hole columns 17 and the first connecting columns 16 can be connected through the screws.

[0027] Please refer to Figure 4 The inside of the main shell 1 is provided with a paper roll groove 6, and the paper roll 15 can be put into the paper roll groove 6.

[0028] The bottom of the paper roll groove 6 (close to one end of the base 2) is evenly provided with a plurality of first supporting ribs 5, which can abut against the waterproof cover 4 when the main shell 1 and the base 2 are connected together, thereby preventing the waterproof cover 4 from moving.
