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.

Abstract: Disclosed is an ice crushing device, and relates to the field of ice crushing technology. The ice crushing device includes a conveying mechanism, a guide mechanism and an ice crushing mechanism. An upper end of the conveying mechanism is open and used for placing ice blocks, and a lower end of the conveying mechanism communicates with an upper end of the guide mechanism; a lower end of the guide mechanism communicates with an upper end of the ice crushing mechanism; the conveying mechanism is used for guiding the ice blocks into the guide mechanism, and the ice blocks in the guide mechanism fall into the ice crushing mechanism through the upper end of the ice crushing mechanism; and the ice crushing mechanism is used for crushing ice. The ice crushing device can improve the ice crushing efficiency and the ice crushing safety.

Abstract: A household water purifier and a filter quick knockdown mechanism thereof are provided. The water purifier includes the filter quick knockdown mechanism, and a housing. The filter included in the filter quick knockdown mechanism and the housing are connected via the filter quick knockdown mechanism. A lower end surface of the filter is movably connected with a pressing plate, and the pressing plate is configured to lift the filter and press the pressing lid of the filter quick knockdown mechanism upon disassembling the filter. The filter quick knockdown mechanism includes a first positioning mechanism and a locking mechanism. When the first positioning mechanism provided on the filter is configured to be mated with a second positioning mechanism provided on the housing, the filter is coupled with the housing via the locking mechanism.

Abstract: A water purification filter element is provided. The water purification filter element may include a filter bottle, a filter material, an end cover, and a water self-stopping and passing structure.

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.
