Anti-corrosion box door air and liquid sealing device

The invention relates to an anti-corrosion box door sealing device, in particular to an anti-corrosion box door air and liquid sealing device. The sealing device is suitable for a refrigerator, a household wardrobe and other occasions. The sealing device can tightly seal the contact position of an anti-corrosion box body and a box door, can also prolong the freshness guarantee period of food in an anti-corrosion box like a refrigerator, and can keep objects in a wardrobe sterile for a long time without preservatives. The anti-corrosion box door air and liquid sealing device is characterized in that a box body sealing ring is arranged on the anti-corrosion box body; an annular rubber pipe is arranged on the inner side and connected with a pressurization pump through a connecting pipe; the pressurization pump is powered by a motor; a box door sealing ring is arranged on the box door; the outer side of the box door sealing ring makes contact with the inner side of the annular rubber pipe; the annular rubber pipe is clamped between the inner side of the box body sealing ring and the outer side of the box door sealing ring; when the pressurization pump inflates air into the annular rubber pipe, the annular rubber pipe expands so that tight sealing between the anti-corrosion box body and the box door can be achieved. When the door is opened, an exhausting valve works, the annular rubber pipe naturally contracts, and the box door can be used normally.
