A reverse osmosis water purifier

Abstract

The invention discloses a reverse osmosis water purifier which comprises a ceramic filter, a granular activated carbon filter, a reverse osmosis membrane filter and a post-activated carbon filter sequentially connected through a pipeline, wherein the ceramic filter is provided with a water inlet connector, a water outlet connector and a wastewater outlet connector; the water inlet connector is connected with a tap water pipe; the water outlet connector is connected with a water inlet end of the granular activated carbon filter; the wastewater outlet connector is connected with an electromagnetic valve; the reverse osmosis water filter is provided with a water inlet a, a water outlet a and a wastewater outlet; the water inlet a is connected with a water outlet end of the granular activated carbon filter; the water outlet a is connected with the water inlet end of the post-activated carbon filter; the wastewater outlet is connected with a wastewater regulating and discharging tool; the water outlet a is further connected with a pressure barrel; the water outlet end of the post-activated carbon filter is connected with a drinking water faucet. The reverse osmosis water purifier provided by the invention replaces PP cotton with a self-cleaning ceramic filter to remove granular impurities, thereby reducing the frequency of replacing a filter element and helping to prolong the service life of the filter element.

Description

technical field [0001] The invention belongs to the field of water purification equipment, in particular to a reverse osmosis water purifier. Background technique [0002] The existing household reverse osmosis water purifier basically uses PP cotton filter element as the first stage filter element to filter out particulate matter impurities in the water. Generally, the PP cotton filter element needs to be replaced after 3-6 months of normal use, and the replacement frequency is relatively low. High, it is inconvenient for the user, and if the replacement is not timely, the life of other filter elements in the rear pipeline will be shortened. [0003] In addition, the invention patent with the patent number of 201610257512.5 provides a ceramic filter element water purifier, which can clean the dirt of the ceramic filter element through the bristles to achieve the purpose of relying on automatic cleaning of the filter element, but has the following defects: 1. When replacing ...

[0003] In addition, the invention patent with the patent number of 201610257512.5 provides a ceramic filter element water purifier, which can clean the dirt of the ceramic filter element through the bristles to achieve the purpose of relying on automatic cleaning of the filter element, but has the following defects: 1. When replacing the filter element, the brush assembly needs to be removed. The ceramic filter element can only be removed, which is inconvenient to operate; 2. The bristles are easy to hide dirt, and the brush assembly needs to be replaced or cleaned at the same time when the filter element is replaced; 3. The brush bristles scrub the dirt on the outer wall of the ceramic filter element while causing wear and tear on the ceramic filter element. But the degree of wear needs to be disassembled to view the water purifier
