Abstract: The present invention relates to a canister-type fan structure and, more specifically, to a canister-type fan structure having a housing, in which wings for generating wind are mounted, of a canister shape having a certain standard to improve a wind blowing efficiency. In addition, the canister-type fan structure has safety net bodies having an optimal shape and mounted to front and rear surfaces of the canister-type housing, so as to blow soft wind close to the natural wind. To this end, the canister type fan structure of the present invention comprises: a canister-type housing which is provided with wings for generating the wind rotatably mounted thereon and has predetermined lengths in forward and backward directions from the mounting position of the wings; and a front safety net body which is mounted on the front surface of the canister-type housing and is provided with protecting ribs so that a plurality of wind holes form a certain pattern.
