Multistage water treatment functional water bottle filter core

Abstract

The invention discloses a multistage water treatment functional water bottle filter core. The multistage water treatment functional water bottle filter core comprises: a shell; a cavity and a filter core main body which are arranged on the shell; a water inlet arranged on the surface of the cavity; a water outlet positioned at the tail end of the filter core main body; a detection system arranged at the edge of the water outlet; a button and a display screen which are arranged at one side of the water inlet; and a filter membrane layer system, a fine filtration layer system, a center pressure bearing tube device, a stable layer system, a high-density fine filtration layer system and a reverse osmosis membrane system which are sequentially arranged in the filter core main body by adopting the flow direction of water entering the water inlet as a forward direction. The button is pressed to open the water inlet and activate the filter core main body, and the water entering the water inlet sequentially goes through the filter membrane layer system, the fine filtration layer system, the center pressure bearing tube device, the stable layer system, the high-density fine filtration layer system and the reverse osmosis membrane system, and is discharged through the water outlet in order to obtain healthy drinking water. The multistage water treatment functional water bottle filter core reserves trace elements needed by human bodies, and removes harmful substances from the drinking water.

Description

technical field [0001] The invention relates to the technical field of kettle filter elements, and more specifically relates to a kettle filter element with multi-stage water treatment function. Background technique [0002] From the beginning of the water purifier, the filter element is the most important component, and the earliest filter element is a filter bottle structure. The purification technology of water purifiers is developing rapidly, but the change of filter element technology is relatively slow. At present, there are mainly three kinds of filter elements recognized, which are ordinary filter elements, grooved filter elements, and skeleton filter elements, and according to the material of filter elements, they can be divided into polypropylene melt blown filter elements, activated carbon filter elements, ceramic filter elements, ultrafiltration filter elements, reverse osmosis filter elements, etc. [0003] Although the kettle filter element used for water trea...

Problems solved by technology

[0003] Although the kettle filter element used for water treatment can be used to treat harmful components in drinking water, after treatment, the drinking water also lacks the trace elements necessary for the human body, so the water treated by the filter element is not necessarily hea
