Technical Field

[0001] The utility model relates to the field of drying boxes, in particular to a sealing structure of a drying box. Background Art

[0002] Drying ovens are divided into two categories: electric blast drying ovens and vacuum drying ovens according to the different drying materials. They are now widely used in chemical, electronic communications, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical, aerospace and colleges and universities and other industries. In order to ensure the sealing effect of the drying oven during operation, a corresponding sealing structure will be set between the box body and the door.

[0003] The Chinese patent with the publication number CN219347249U discloses a drying box sealing structure, which includes a drying box body, a butt seal groove is fixedly installed on the front of the drying box body, a sealing airbag is fixedly installed on the inner wall of the butt seal groove, a pneumatic mechanism is fixedly installed on one side of the drying box body, and the output end of the pneumatic mechanism is connected to the sealing airbag, and a box cover is movably installed on the drying box body, and a first sealing head and a second sealing head that are butt-matched with the butt seal groove are fixedly installed on the inner side of the box cover. The technical solution of the application achieves the effect of double-layer closed sealing by setting the mutual docking between the first sealing head and the second sealing head and the butt seal groove, which is more significant than the traditional single-layer and fitting sealing structures, and the double-layer butt seals are all touched and pressed against each other by rubber material layers to prevent the flow of air and other media, thereby ensuring the operating performance of the drying box body.
