On the other hand, the embodiments of the present invention disclosed in the specification and drawings are merely presented specific examples to easily explain the technical contents of the present invention and help the understanding of the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention can be carried out in addition to the embodiments disclosed herein.

The present invention is a facility for spraying liquids such as water or disinfectant to public facilities, food processing facilities, industrial water cooling towers, meat processing equipment, food and food preparation equipment, or spraying liquids such as water or pesticides on agricultural products or crops It can be used in various fields such as.

Claims
