The invention relates to the field of seal, in particular to a box type seal structure. The whole box type seal structure is in a ring shape and includes dustproof rings, a skeleton and at least one centrifugation lip portion, containing space is formed between the skeleton and the dustproof rings, and a gas inlet hole which communicates with the containing space is formed in the skeleton; and thecentrifugation lip portions are arranged at the skeleton and extend out of the skeleton to abut against the dustproof rings. When a first member and a second member are relatively rotated, airflow which flows into the containing space from the gas inlet hole of the skeleton can separate at least one centrifugation lip portion from the dustproof rings to form predetermined intervals and the airflow can flow out of the box type seal structure from the predetermined intervals. According to the box type seal structure, a static seal and a dynamic seal can be provided for a rotating assembly according to the seal of the seal lip portions and an air seal.
