  • 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: 20230138998
    Abstract: A household water purifier includes a main unit and a filter assembly arranged in the main unit. The filter assembly includes a composite filter core. The composite filter core includes a filter bottle and a filter element located in the filter bottle. The filter element is of a separated structure. In the household water purifier, the filter element is located in the filer bottle; during use, when the filter element needs to be replaced, the filter element can be directly taken out of the filter bottle for replacement; Furthermore, the filter element itself is of a split structure. It is no need to replace the filter element as a whole, just some failed components of the filter element need to be replaced, which further improves convenience of replacement and maintenance of the filter core of the water purifier, and saves maintenance and use costs of the water purifier.
