Composite filter element and water purification equipment

Abstract

The invention discloses a composite filter element and water purification equipment, wherein the composite filter element comprises a filter element joint, an outer barrel, an inner barrel, a separation disc, a first filer core and a second filter core; the upper end of the outer barrel is connected with the filter element joint in a sealing manner; the inner barrel is arranged in the outer barrel, and the upper end of the inner barrel is connected with the filter element connector in a sealed mode; the separation disc seals the lower end of the inner barrel, so that the inner barrel and the outer barrel form a first filter cavity and a second filter cavity which are relatively independent, the interior of the inner barrel is a first filter cavity, the exterior of the inner barrel is a second filter cavity, and a gap is formed between the outer side of the inner barrel and the inner side of the outer barrel to form a water inlet channel of the second filter cavity; the first filter element is arranged in the first filter cavity; and the second filter element is arranged in the second filter cavity and is positioned below the separation disc. According to the invention, independentfiltration of two water qualities is further realized so as to meet the filtration requirements of users on various water qualities.

Description

[0001] This application is a divisional application with the application number "201710223346.1" and the invention name "composite filter element and water purification equipment". technical field [0002] The invention relates to the field of water purification equipment, in particular to a composite filter element and water purification equipment. Background technique [0003] With the development of society, people have higher and higher requirements for water quality. In water purification equipment, composite filter elements are generally equipped with multiple filter elements, and their filtering effect is better, so they are widely used. However, in the current composite filter element, the composite filter element has only one set of water inlets. If the water quality of multiple waterways needs to be filtered separately, multiple composite filter elements need to be installed, which causes a lot of inconvenience, and a single composite filter element cannot satisfy t...

However, in the current composite filter element, the composite filter element has only one set of water inlets. If the water quality of multiple waterways needs to be filtered separately, multiple composite filter elements need to be installed, which causes a lot of inconvenience, and a single composite filter element cannot satisfy the user's requirements. Various water quality filtration needs
