Water channel device, composite filter cartridge device and composite filter cartridge filtering system

Abstract

The invention discloses a water channel device, a composite filter cartridge device and a composite filter cartridge filtering system. The water channel device is provided with various sequentially circulating water channels from outside to inside in the water flow direction between the top end and the bottom end of a column, wherein the water channels comprise a water inlet channel, a first middle water channel, a second middle water channel and a water outlet channel sequentially from outside to inside. The composite filter cartridge device comprises the water channel device and a compositefilter cartridge arranged in the water channel device in a filling manner. The composite filter cartridge filtering system comprises the composite filter cartridge device and a raw water tank, and thecomposite filter cartridge device is mounted in the raw water tank. Matching of different filter cartridge materials can be realized, size of the water channel structures of the water channel devicecannot be changed by matching of the different filter cartridge materials, and different filter cartridges can be conveniently replaced for matching; filtering time can be prolonged, so that filteringis more sufficient; use ratio is higher under the condition of equal quantity of consumed materials, and accordingly, the filtering effect is better and the filtering life is longer.

Description

Technical field [0001] The invention relates to the field of water purification, in particular to a waterway device, a composite filter element device and a composite filter element filter system. Background technique [0002] In current water purification equipment, generally multiple filter element devices are connected in series or in parallel. Although this design can solve some water purification problems, it is generally difficult to replace the filter element, or the matched filter element is difficult to replace, and the filter element is relatively fixed. If a filter element device is to be replaced, it is equivalent to dismantling the entire structure. [0003] For example, CN203768171U discloses a filter element device built in a water purifier, see figure 1 As shown, its 13-stage filter element devices are connected in series. If you want to replace and match other filter elements, you must remove the entire structure and reconnect it in series. Moreover, the more le...
