Referring to fig. 1 to 3, a novel moisture-proof structure 10 for sealing a fresh storage tank in an embodiment includes a tank body 100, a first cover body 200 and a second cover body 300, wherein a containing cavity is formed in the tank body 100, a taking and placing opening 120 communicated with the containing cavity is formed on the tank body 100, and a curling protrusion 110 is formed at the edge of the taking and placing opening 120; the first cover 200 is detachably covered on the picking and placing port 120, a communication port 220 is formed on the first cover 200, the communication port 220 can be communicated with the accommodating cavity through the picking and placing port 120, a clamping protrusion 210 is formed on the first cover 200, and the clamping protrusion 210 can be clamped on the hemming protrusion 110, so that the first cover 200 and the can 100 are in sealing connection; the second cover 300 is detachably covered on the communication port 220, and the second cover 300 is in interference fit with the communication port 220, so that the second cover 300 is in sealing connection with the first cover 200.

The first cover 200 is first covered on the pick-and-place opening 120. The sealing connection between the first cover 200 and the can body 100 is achieved by the engagement between the catching protrusion 210 and the beading protrusion 110. And then the second cover 300 is covered on the communication port 220 of the first cover 200, and the sealing connection between the second cover 300 and the first cover 200 is realized through the interference fit between the second cover 300 and the first cover 200. And further, a sealing structure is provided at each structural joint, ensuring sealability between the first cover 200, the second cover 300 and the can 100. Meanwhile, the hemming protrusion 110 and the catching protrusion 210 have simple structures and simple manufacturing processes.

The overall production costs of the moisture barrier structure 10 are further reduced.

Referring to fig. 2 and 3, in an embodiment, the first cover 200 is further formed with a first cavity 230 and a connection port 240 that is communicated with the first cavity 230, the inner wall of the first cavity 230 is formed with the clamping protrusion 210, one end of the can 100 with the access opening 120 can pass through the connection port 240 and be arranged in the first cavity 230, the communication port 220 is communicated with the access opening 120 through the first cavity 230, and the inner wall of the first cavity 230 can abut against the outer surface of the can 100, so that the first cover 200 and the can 100 are connected in a sealing manner. When one end of the can body 100 with the taking and placing opening 120 is penetrated in the first cavity 230, the clamping protrusion 210 and the curling protrusion 110 are mutually clamped to form primary sealing connection between the first cover body 200 and the can body 100. At the same time, the inner wall of the first cavity 230 abuts against the outer surface of the can 100, so that the first cover 200 and the can 100 are again in sealing connection. Avoiding failure of the entire moisture barrier structure 10 after failure of any one of the sealing connections between the first cover 200 and the can 100.
