Pressure water storage tank with water purification function and using method thereof

Abstract

The invention relates to a pressure water storage tank having a water purifying function. The pressure water storage tank comprises a tank body, wherein a filter core chamber in which a filter core is mounted is arranged in the tank body; a water storage chamber is formed between the outer wall of the filter core chamber and the inner wall of the tank body; the lower side of the filter core chamber is communicated with a tap water connector; a non-direct drinking water tap is arranged on the top of the filter core chamber; the side part of the filter core chamber is communicated with the water storage chamber through a one-way valve; a direct drinking water tap is connected to the water storage chamber; a piston tightly clung to the wall of the water storage chamber is arranged in the water storage chamber; a spring is arranged below the piston. The pressure water storage tank having the water purifying function is simple in structure and can realize preparation of non-direct drinking water and direct drinking water; the non-direct drinking water is not treated with an ultrafiltration member, has large water volume, and is used for washing the ultrafiltration membrane during use; the direct drinking water is treated with the ultrafiltration membrane and has a high purifying degree, and when water preparation stops when the water pressure in the water storage chamber and the elasticity of the spring are balanced, water storage is realized.

Description

technical field [0001] The invention provides a pressure water storage tank with water purification function and a using method thereof. Background technique [0002] The traditional water storage tank has a single structure, which cannot realize magnetization treatment and separate non-direct drinking water and direct drinking water, resulting in low water volume, low water utilization rate, unclear degree of purification, and inconvenient water storage. Contents of the invention [0003] The object of the present invention is to provide a pressurized water storage tank with water purification function and its usage method in view of the above deficiencies. [0004] The solution adopted by the present invention to solve the technical problem is a pressure water storage tank with water purification function, including a tank body, the inside of the tank body is provided with a filter element cavity for installing a filter element, and the outer wall of the filter element c...
