Abstract
Exemplary embodiments of a filter cartridge for a coffee machine are disclosed. According to one exemplary embodiment, a coffee machine filter cartridge may include a filter body having a water inlet, a grate and a water outlet, and a lid held on the filter body. The water inlet is disposed around the water outlet. The water outlet connects to one end of the grate through a pipe. The other end of the grate is held on the inner wall of the filter body and comprises a cloth filter. A filter chamber between the pipe and the filter body has a descaling core. When filtering and descaling, the water flows sequentially through the water inlet, filter chamber, grate, cloth filter, pipe, and water outlet. The cartridge is structurally simple, convenient and accessible to users; preventing clogging of the internal parts of the coffee machine by slow dissolution of the descaling agent.
