  • Patent number: 11958015
    Abstract: A dual-purpose household water purifier includes a main unit and an expansion unit which can be detachably connected. When the main unit is connected with the expansion unit, a booster pump can pressurize tap water entering a filter assembly. In the dual-purpose household water purifier, the main unit can be used as a non-electric drive water purifier. After the tap water enters the filter assembly and is filtered. The purified water flows into the purified water chamber of the pressure bucket, and the user takes the purified water. It is further provided an expansion unit. When the main unit is connected to the expansion unit, the booster pump can pressurize the pipeline, reducing application environmental restrictions on the water purifier. Through arrangement of the expansion unit, the water purifier can be operated in two operation modes of non-electric drive mode and electric drive mode.

  • Publication number: 20240041249
    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.
