[0002] PP cotton filter layer is a common water filter material, usually used for primary filtration of water purification equipment. The main function of PP cotton is to filter large particles of impurities in water, such as sand, rust, suspended matter, etc. Its filtration accuracy is generally between 1 micron and 5 microns. When the PP cotton is obviously discolored, blocked, or the water flow becomes very slow, it needs to be replaced. The operation of replacing the PP cotton filter layer is relatively simple. Usually, open the corresponding filter cartridge or filter element housing, take out the old PP cotton, and put in the new one;

[0003] During the filtration process of PP cotton, impurities accumulate at the water inlet of PP cotton to cause blockage, which will reduce the effective area for water to pass through, causing the water flow rate to slow down, thereby reducing the working efficiency of the entire filtration system and affecting the water output of the water purification equipment. Local impurity accumulation will cause this part of the PP cotton to reach saturation faster, thereby shortening the effective use time of the entire PP cotton filter layer and requiring more frequent replacement, which makes the PP cotton replacement more frequent.

[0018] In this embodiment: the annular filter tube 1 is used to connect with the water pipe through the upper connecting tube 12 and the lower connecting tube 13, so that when the water circulates, it can be filtered through the annular PP cotton 3 installed in the annular filter tube 1. Since the upper connecting tube 12 and the lower connecting tube 13 are respectively located at the top and bottom of the outer wall of the annular filter tube 1, the upper connecting tube 12 and the lower connecting tube 13 can transmit water. When the water can be transmitted into the annular filter tube 1, the water can be affected by the ring shape of the annular filter tube 1, so that when the water is transmitted, it can be diverted, and the annular PP cotton 3 filled in the annular filter tube 1 can filter the diverted water, so that when the water is transmitted to the position of the lower connecting tube 13, the water can be filtered by the annular PP cotton 3, and the absorption degree of the annular PP cotton 3 to impurities during diversion can be It can share the burden and reduce the serious accumulation of impurities in a certain section, so as to avoid the rapid reduction of the service life of the annular PP cotton 3.
