Liquid cleaning element, liquid cleaning system, and method for producing a liquid cleaning element

A liquid cleaning filter element comprising:

• at least one cleaning medium configured to filter a liquid;
• a carrier medium configured to enable detachable mounting of the liquid cleaning filter element to a holder part, the carrier medium comprising:
• a first side of the carrier medium having a drainage structure, the at least one cleaning medium arranged at and fixed onto the first side of the carrier medium;
• the drainage structure formed on the first side of the carrier medium, the drainage structure formed as a plurality of spaced apart cylindrical projections which project outwardly away from the first side of the carrier medium;
• wherein the plurality of spaced apart cylindrical projections contact against the at least one cleaning medium and space the at least one cleaning medium away from the first side of the carrier medium, forming an intermediate fluid receiving space between the at least one cleaning medium and the carrier medium;
• an oppositely arranged second side of the carrier medium;
• wherein an outer rim of the at least one cleaning medium is adhesively fixed onto or material-fused to the first side of the carrier medium, such that the intermediate fluid receiving space between the at least one cleaning medium and the carrier medium is closed at the outer rim relative to an external environment of the liquid cleaning filter element;
• wherein the carrier medium further comprises
• at least one liquid connector configured to connect to at least one line for liquid to be cleaned or cleaned liquid;
• wherein the liquid cleaning filter element comprises
• at least one bend in at least one section provided with the at least one cleaning medium and with the carrier medium;
• wherein the carrier medium, prior to being connected to the at least one cleaning medium, is pre-manufactured in a final shape of the liquid cleaning filter element;
• wherein the carrier medium has a pre-defined curved or bend shape, the pre-defined curve or bend extending at least partially circumferentially relative to a circumference of the liquid cleaning filter element about an imaginary axis of the liquid cleaning filter element;
• wherein the carrier medium is formed of a material providing mechanical stability to hold the predefined curve or bend shape and provides mechanical stability to the liquid cleaning filter element;
• wherein the first side of the carrier medium is a radially outer surface;
• wherein the at least one liquid connector comprises
• a cylindrical suction socket arranged at or fixed onto or integrated in one piece with the oppositely arranged second side of the carrier medium.
