Problems solved by technology

Therefore, the filter elements of water purification products are consumables and need to be replaced after a period of use. The service life of the filter element and the cost of replacing the element have become common pain points for consumers and manufacturers.
[0003] Among them, due to the large differences in water quality in various places, the size of particulate matter in the water is also different, resulting in the problem of clogging of the filter element in the process of filtering large particulate matter, the service life of the filter element is greatly shortened, and the filtering effect is deteriorated, resulting in excessive cost of use of the filter element. High; and large particles of impurities and dirt and scale remain on the surface of the filter element, which is inconvenient to clean, increases user workload, and affects user experience; at the same time, the range of raw water quality applicable to water purification products is limited, reducing the practicability of water purification products and affecting Promotion and application of water purification products

Abstract

The present application discloses a self-flushing multi-stage filter element assembly, which includes a first water path connecting the raw water port and the clean water port, a second water path connecting the raw water port and the flushing port, and a The filter screen and the first filter unit are sequentially arranged in the first water channel along the water flow direction in the housing, the filter front end of the filter screen is connected to the second water channel, and the filter rear end of the first filter unit is connected to the second water channel. The water purification port is connected, and in the filtering state, the first waterway is connected; in the flushing state, the second waterway is connected, and the raw water flows from the filter front side of the filter screen to flush the filter. The self-rinsing multi-stage filter element assembly is equipped with a filter screen, the permissible raw water quality range of the filter element assembly is expanded, and the applicable area is wider, and the structure is simple, the installation is compact, the volume of the filter element assembly is greatly reduced, and the installation space is saved.

Description

technical field [0001] The application belongs to the technical field of water purification equipment, and in particular relates to a self-flushing multi-stage filter element assembly. Background technique [0002] In recent years, with the continuous improvement of people's living standards, people pay more and more attention to the quality of drinking water, making the water purification market hot, water purification products have become popular, and become the most potential products in the field of household appliances; at the same time, water purification products are updated The pace is accelerating and the industry technology is constantly improving. Water purification products purify the raw water through the filter element to obtain directly drinking water; as the use time prolongs, impurities in the raw water will block the filter element, so it is necessary to remove and wash or replace the filter element regularly to ensure the normal operation of the water puri...
