Ultra-precise multi-stage purification filter

Abstract

The invention discloses an ultra-precise multi-stage purification filter, which comprises an outer shell and a multi-stage purification filtering device. A first-stage filtering structure and a tubular second-stage filtering structure are arranged in the outer shell; one end of the first-stage filtering structure is connected to a water source, and the other end is connected to a water inlet; oneend of the second-stage filtering structure is connected to the water inlet, and the other end is connected to a drain outlet; a third-stage filtering structure is arranged around the second-stage filtering structure in a surrounding manner; a fourth-stage filtering structure is arranged around the third-stage filtering structure in a surrounding manner; water passing through the first-stage filtering structure is filtered out through the second-stage filtering structure, the third-stage filtering structure and the fourth-stage filtering structure in sequence and then flows out from a water outlet. The ultra-precise multi-stage filter is mainly used for household fish tanks, and has a four-stage filtering structure, which can filter and adsorb silt bacteria and other pollutants of different diameters stage by stage, the filtered water is purer, does not breed bacteria easily, and reduces the frequency of water changing and fish tank wall cleaning.

Description

technical field [0001] The invention relates to the technical field of household water purifiers, in particular to an ultra-precise multi-stage purification filter. Background technique [0002] In order to beautify the home environment, almost all modern families have fish tanks. Some people use small fish tanks to raise small fish, and it is more convenient to change the water manually, but most people use larger fish tanks. The fish kept in the fish tank are bigger and more numerous. The water environment in the fish tank will be polluted in a short time. It is necessary to change the water and clean the tank wall in time, but on the one hand, the fish tank is fragile, and on the other hand, it is heavy and difficult to move , causing difficulty in cleaning. [0003] In view of the above problems, in the prior art, the fish tank is generally connected with the filter, and the filtered water is passed into the fish tank. The impurities contained in the filtered water are ...

Problems solved by technology

However, since the above method is only filtered once, the filtering effect is not ideal, and the above problems cannot be solved relatively thoroughly.
