In order to solve the above problems, the utility model provides a kind of filtration core：
A kind of filtration core, including upper lid, the element kit being mutually screwed, the element kit wrap successively from outside to inside
Include shell, nonwoven layer, coconut husk charcoal and ion exchange resin mixed layer, porous ceramic layer, doughnut film layer；The shell bag
Include the end cap portions and shell body of mutual integral type connection, the end cap portions or on be covered with through hole for water inlet, end cap portions
Diameter, which is more than shell body and is screwed with upper lid composition, to be connected, and the inside of shell body is provided with annular relief, annular relief
The gap for sewage flow is provided with the outer wall of shell body, annular relief is circumferentially with multiple inlet openings and middle be provided with is held
Receive the cavity of each filter layer, cavity upper end is provided with closure and lower end is provided with outlet pipe.
Preferably, cellular multiple apopores are provided with the outlet pipe, the upper end of the apopore is provided with non-woven fabrics
Layer.
Preferably, the square through hole for being circumferentially with multiple grid arrangements of the end cap portions.
Preferably, the lower edge of the end cap portions is provided with the fixture for being used for fixing filtration core.
Preferably, the fixture is screens hooking structure.
Preferably, it is provided with sealing ring between fixture and the shell body.
Preferably, the upper end of the upper lid is provided with up big and down small tubaeform lug boss.
Preferably, the inlet opening is the small flared structure of outer imperial palace.
The utility model has the advantages that：Sewage can only enter cavity inside by gap from inlet opening, improve
Effective contact area of filter layer and sewage, improves purification efficiency.
