The invention relates to the field of the hose industry and discloses a multifunctional hose and a manufacturing method thereof. The multifunctional hose comprises a large-diameter hose body. A small-diameter hose body is arranged in the large-diameter hose body. A plurality of interlayer materials are arranged on the outer surface of the small-diameter hose body and the inner surface of the large-diameter hose body at intervals and are distributed sequentially on the same straight line in the length direction of the small-diameter hose body. Strip-shaped glue is further arranged between the small-diameter hose body and the large-diameter hose body and on the straight line the same as that of the interlayer materials in the length direction of the small-diameter hose body. The parts, where the small-diameter hose body makes contact with the large-diameter hose body directly, are bonded by the glue, while the parts isolated by the interlayer materials are not bonded. With the usage of the interlayer materials, the effect that only partial bonding is formed between the small-diameter hose body and the large-diameter hose body is achieved, thus movement synchronization and connection firmness of the small-diameter hose body and the large-diameter hose body are achieved, and better flexibility, balance performance and bendability of the hose are achieved. The manufacturing method is simple and convenient and easy to conduct.
