Abstract:
The present invention relates to a sprayer having a liquid injection port arranged, at a position at which the ratio of a compressed air volume to a liquid volume is optimum, on a circumference of a main body of a liquid tank. The sprayer comprises: a liquid tank having a predetermined space for storing a liquid; an air-receiving unit arranged on an upper surface of the liquid tank so as to receive air injected from the outside; a safety valve arranged on the upper surface of the liquid tank such that the safety valve operates when the internal pressure of the liquid tank reaches a limit; a liquid injection port tilted at a predetermined angle and protruding upwardly from a portion of the circumference of the main body of the liquid tank, and attached to the point on the circumference of the main body of the liquid tank at which the ratio of the compressed air volume to the liquid volume is 1:1 to 1:1.5; and an injection unit connected to the liquid tank to inject a liquid. The sprayer of the present invention can be conveniently and easily used by anyone, enables the amount of liquid to be filled into the sprayer to be easily calculated, and reduces manufacturing costs and manufacturing processes.
