Filter cartridge and filter having same

A filter cartridge (1, 1A, 2), the filter cartridge (1, 1A, 2) comprising:

• a filter cartridge housing portion (10), the filter cartridge housing portion (10) being provided with a water inlet (14);
• and
• a filtration unit (20), the filtration unit (20) being provided in the filter cartridge housing portion (10);
• the filter cartridge being characterized in that the filtration unit (20) is provided with a front filtration medium and a rear filtration medium;
• the filtration unit (20) is configured to cause raw water flowing into the filter cartridge housing portion (10) by means of the water inlet (14) to be filtered by the front filtration medium to obtain a first filtered fluid;
• and the first filtered fluid selectively flows toward a first water outlet (15), and/or flows toward a second water outlet (16) after being filtered by the rear filtration medium;
• wherein the filtration unit (20) comprises a hollow cover (23), an inner housing (22, 22A), and a mounting base (21);
• the cover (23) is sealedly connected to the inner housing (22, 22A);
• the front filtration medium is mounted between the inner housing (22, 22A) and the mounting base (21);
• a first filtered fluid channel (F1) is formed in the filtration unit (20);
• the first filtered fluid filtered by the front filtration medium enters the first filtered fluid channel (F1);
• an accommodation space (C1, C2) is formed in the inner housing (22, 22A);
• the rear filtration medium is provided in the accommodation space (C1, C2);
• the inner housing (22, 22A) is configured so that the accommodation space (C1, C2) is located downstream of the first filtered fluid channel (F1), in fluid communication with the second water outlet (16), and selectively in fluid communication with the first filtered fluid channel (F1);
• wherein the filtration unit (20) further comprises a valve member (41, 27) provided in the inner housing (22, 22A), and the valve member (41, 27) is configured to selectively open or close according to fluid pressure in the filter cartridge (1, 1A, 2) so that one or both of the first water outlet (15) and the second water outlet (16) are selectively in fluid communication with the first filtered fluid channel (F1);
• and
• wherein the first water outlet (15) is in fluid communication with the first filtered fluid channel (F1), and the valve member (41) is configured to selectively cause the second water outlet (16) to be in fluid communication with the first filtered fluid channel (F1).
