Integrated reverse osmosis filter element

Abstract

The invention relates to an integrated reverse osmosis filter element. A water collecting pipe is arranged at the center of the reverse osmosis filter element, a water collecting hole is formed in the water collecting pipe, and purified water filtered by the reverse osmosis filter element is collected by the water collecting hole and flows into the water collecting pipe; and a rear filter element is arranged in the water collecting pipe, and the rear filter element further filters the purified water flowing into the water collecting pipe. By virtue of the arrangement, the rear filter element is arranged in the water collecting pipe of the reverse osmosis filter element in an integrated way, so that the reverse osmosis filter element integrates the rear filter element which has the functions of improving taste of the purified water filtered by a reverse osmosis membrane and adding minerals; meanwhile, overall size of the integrated reverse osmosis filter element after integration is not changed, and the aims of optimizing design, reducing the number of the filter elements and improving filter element integration level are achieved; and besides, the integrated reverse osmosis filter element provided by the invention is simple in structure, obvious in effect and applicable to popularization and application.

Description

technical field [0001] The invention relates to a filter element in the field of water purifiers, in particular to an integrated reverse osmosis filter element integrated with a rear filter element. Background technique [0002] At present, reverse osmosis water purifiers are composed of multi-stage filter elements, each of which is wrapped by a filter bottle. Traditional water purifiers have at least four filter bottles, which leads to many pipe joints, increased risk of water leakage, and high cost. When consumers replace filter elements, they need to replace each filter element regularly, which is costly and inconvenient to replace. [0003] In particular, the reverse osmosis filter element and the post-filter element of the reverse osmosis water purifier (the post-filter element is installed in the downstream pipeline of the reverse osmosis filter element, to filter the purified water filtered by the reverse osmosis filter element again to add minerals Components) are i...

Problems solved by technology

[0002] At present, reverse osmosis water purifiers are composed of multi-stage filter elements, and each filter element is wrapped by a filter bottle. Traditional water purifiers have at least four filter bottles, which leads to many pipe joints, increased risk of water leakage, and high cost

When consumers change the filter elements, they need to replace each filter element regularly, the replacement cost is high, and it is inconvenient to replace the filter elements

[0003] In particular, the reverse osmosis filter element and the post-filter element of the reverse osmosis water purifier (the post-filter element is installed in the downstream pipeline of the reverse osmosis filter element, to filter the purified water filtered by the reverse osmosis filter element again to add minerals Components) are installed in different filter bottles, resulting in inconvenient installation of the machine, increasing the size of the whole machine, and increasing the number of joints
