Specifically, the independent first flow channel 510 and the independent second flow channel 520 inside the housing 100 are not communicated with each other, so that when the filter element assembly 10 is used, two paths of water can be filtered at the same time, and each path occupies one flow channel respectively. Or the same water is filtered for multiple times according to the sequence, and the water is filtered through one flow passage of the filter element assembly 10 and then directly returned or is filtered through the other flow passage of the filter element assembly 10 after being treated. In the following, when the filtering sequence is referred to, the water is filtered through the first filter element 610 and then through the second filter element 620, that is, the first filter element 610 is used as a front filter element and the second filter element 620 is used as a rear filter element, but it should be noted that the second filter element 620 may be used as a front filter element according to the actual situation, and the first filter element 610 is a rear filter element, which is not described herein.
The first filter element 610 or the second filter element 620 is a PP cotton filter element, an activated carbon filter element or a PP cotton and activated carbon composite filter element. PP cotton is commonly used to filter large particle impurities in water and activated carbon is commonly used to adsorb small particle impurities in water. Therefore, PP cotton is mostly used in the pre-filter element to carry out rough filtration on water; activated carbon is mostly used in a rear filter element to further improve water quality; in the PP cotton and activated carbon composite filter element, water flow is designed to flow through the PP cotton and then through the activated carbon, so that the composite of the filtering function is realized, and the filtering effect is improved.
In the filter element assembly 10, the first water passage 510 is communicated with the first water passing port 111 and the second water passing port 112 on the surface of the housing 100, the first filter element 610 is arranged in the first water passage 510, the first water passing passage 511 of the first water passage 510 is formed between the first water passing port 111 and the first filter element 610, the second water passing passage 512 of the first water passage 510 is formed between the second water passing port 112 and the first filter element 610, the first water passing passage 511 and the second water passing passage 512 are separated by the first filter element 610, that is, before and after filtration through the first filter element 610, water in the first water passing passage 511 and the second water passing passage 512 can be communicated with each other only through the first filter element 610, so that the water before and after filtration is directly mixed to cause filtration failure. In the first flow channel 510, water can flow from the first water passing port 111 into the filter element assembly 10, flow to the first filter element 610 through the first water passing channel 511, flow to the second water passing port 112 through the second water passing channel 512 after being filtered by the first filter element 610, and flow out of the filter element assembly 10 from the second water passing port 112. Alternatively, the water flow may flow reversely, i.e. from the second water passing port 112 into the filter element assembly 10, flow to the first filter element 610 through the second water passing channel 512, flow to the first water passing port 111 through the first water passing channel 511 after being filtered by the first filter element 610, and flow out of the filter element assembly 10 from the first water passing port 111. Hereinafter, the case of the first water flow direction will be described as an example, and the case of the second water flow direction will not be described again.
In the filter element assembly 10, the second flow passage 520 is communicated with the third water passing opening 121 and the fourth water passing opening 122 on the surface of the housing 100, the second filter element 620 is arranged inside the second flow passage 520, a third water passing flow passage 521 of the second flow passage 520 is formed between the third water passing opening 121 and the second filter element 620, a fourth water passing flow passage 522 of the second flow passage 520 is formed between the fourth water passing opening 122 and the second filter element 620, that is, before and after filtration through the second filter element 620, water in the third water passing flow passage 521 and the fourth water passing flow passage 522 can be communicated with each other only through the second filter element 620, so that the water before and after filtration is directly mixed to avoid filtration failure. In the second flow path 520, water may flow from the third water passage 121 into the filter element assembly 10, through the third water passage 521 to the second filter element 620, filtered by the second filter element 620, and then through the fourth water passage 522 to the fourth water passage 122, and out of the filter element assembly 10 from the fourth water passage 122. Alternatively, the water flow may flow reversely, i.e. from the fourth water passing port 122 into the filter element assembly 10, flow to the second filter element 620 through the fourth water passing channel 522, flow to the third water passing port 121 through the third water passing channel 521 after being filtered by the second filter element 620, and flow out of the filter element assembly 10 from the third water passing port 121. Hereinafter, the case of the first water flow direction will be described as an example, and the case of the second water flow direction will not be described again.
The housing 100 of the cartridge assembly 10 has a vertically extending column shape, and the first water flow passage 511, the second water flow passage 512, the third water flow passage 521, and the fourth water flow passage 522 extend in the vertical direction inside the housing 100. The center direction of the cross section of the columnar shell is taken as the inner side, and the center direction of the cross section of the columnar shell is taken as the outer side. The first water flow channel 511, the second water flow channel 512, the third water flow channel 521 or the fourth water flow channel 522 surrounds one circle or less than one circle relative to the center of the cross section on the cross section perpendicular to the extending direction of the housing 100, that is, the water flows up and down along the complete cylindrical surface or up and down along a part of the cylindrical surface inside the housing 100. The flux of each water flow passage increases with the cross-sectional area of the water flow passage. In contrast, when the first water flow channel 511, the second water flow channel 512, the third water flow channel 521 and the fourth water flow channel 522 surround the center of the cross section for one circle, that is, the water flows in the first water flow channel 511, the second water flow channel 512, the third water flow channel 521 and the fourth water flow channel 522 all flow up and down along the complete cylindrical surface inside the casing 100, the distribution of the water flows inside the casing 100 is more uniform and stable, the space utilization inside the casing 100 is greater, which is beneficial to improving the flux of the filter element assembly 10 and improving the filtering efficiency, and will be described in detail later.
Further, the first water flow channel 511, the second water flow channel 512, the third water flow channel 521 and the fourth water flow channel 522 may be configured as a cylinder or a combination of cylinders to reduce the deposition of impurities in the water flow channels and prolong the service life of the filter element assembly 10.
