Water purifying device for field use

Abstract

The invention relates to a water purifying device for field use. The water purifying device for field use comprises a metal shell and a filter element. A base is arranged on the bottom of the shell, and a stretchy cylinder is arranged in the base. A piston is arranged in the shell and connected with a pull rod of the stretchy cylinder. A limiting block for limiting is arranged below the piston. The limiting block is provided with a first through hole matched with the pull rod and a second through hole used for installing the filter element. The shell is further provided with a water inlet located in the side wall of the upper portion of the shell and a water outlet tap located on the side wall of the lower portion of the shell. The base is further provided with a storage battery set. An exhaust hole is formed in the side wall, below the limiting block, of the shell, and an electromagnetic valve is arranged in the exhaust hole. When water using is not in hurry, raw water can be poured into the shell from the water inlet and is slowly purified by the filter element by means of gravity of the raw water; when water using is in hurry, the stretchy cylinder can drive the piston to move so that the raw water can be pressurized and the filtering and purifying speed can be accelerated; the device is high in water purifying capacity, reliability and one-time water purifying amount.
