A spray device for spraying liquid is provided to form an air supply portion and a tank to be separated to reduce the weight that a user sustains with his/her back and to reduce the user's fatigue. A spray device for spraying liquid includes a body(110), a tank(120), a power generating portion and a handle portion. A user carries the body in his/her back. The tank is mounted on the body to store liquid. The power generating portion is mounted on the body to generate power. The handle portion supplies air to the tank by the power of the power generating portion, and sprays the liquid of the tank to the outside at the same time. In the body, a frame is installed and a back support plate and a shoulder strap(114) are installed on the front of the frame. |
