Abstract

The present invention relates to a liquid sprayer having a cylinder and a piston, wherein, in order to increase a spraying time period and to simplify the construction thereof, such an arrangement is adopted that the piston stroke is designed to be longer, and, when the stroke is longer, loosenesses of a spray head, the piston and the like are avoided and liquid is sprayed with a stable operation. The liquid sprayer comprises: an erected wall engaged with the top portion of the cylinder and mounted on the outer or inner side of the mouth-neck portion; a guide tube connected to the bottom end of the erected wall, surrounding the erected wall from outside and being erected at a predetermined interval from the erected wall; and a slidable tube formed on a member at the side of moving the piston and coupled into the interval formed between the erected wall (17) and the guide tube in a manner to be movable vertically. The slidable tube is guided by the guide tube, so that, even if a stem is longer, the slidable tube can be vertically operated in a stable manner.
