Abstract

The invention discloses a composite filter core assembly, which comprises a shell, a first filter group and a second filter group, wherein the interior of the shell is divided into a first containingcavity and a second containing cavity in the length direction, the two containing cavities are separated through a transition plate, a transition opening is formed in the transition plate, the water pressure in the second containing cavity is larger than the water pressure in the first containing cavity, a water stop structure is arranged at least one inlet and outlet in the shell, the first filter group is arranged in the first containing cavity, the second filter group is arranged in the second containing cavity, the water stop structure comprises a water stop concave table, a water stop core and a water stop spring, the water stop concave table is connected to the shell, the water stop core can move between a cut-off position and a conduction position, the water stop structure blocks the inlet and outlet when the water stop core is in the cut-off position, the inlet and outlet communicates with the interior of the shell when the water stop core is in the conduction position, and thewater stop spring is connected between the water stop concave table and the water stop core, and normally drives the water stop core to move towards the cut-off position. The composite filter core assembly disclosed by the embodiment of the invention is high in integration level and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of water purification, in particular to a composite filter element assembly. Background technique [0002] The tap water transported from urban waterworks to users usually contains a certain amount of salt ions, metal substances, chlorides, microorganisms, sediment and other substances. In order to improve the quality of drinking water, more and more families choose to install water purifiers on the outlet pipes of tap water. The water purifiers have filter elements with multiple functions to remove different types of harmful substances in tap water. [0003] Usually, the existing water purifier filter elements are generally 3 to 4 grades, and some manufacturers' water purifier filter elements are double-core. In order to improve the filtering effect of the composite filter element assembly, a variety of filter element assemblies are usually arranged in the water purifier. The inlet and outlet ports between...
