Multi-layer purification filter bottle assembly of intelligent single-stage composite integrated RO (Reverse Osmosis) filter element

Abstract

The invention relates to the technical field of water purifiers, in particular to a multi-layer purification filter bottle assembly of an intelligent single-stage composite integrated RO filter element. Compared with the prior art, the multi-layer purification filter bottle assembly is provided with a filter bottle cover and a filter bottle, on one hand, a first interface disc is arranged in the filter bottle cover, so that the first interface disc is rotationally connected with a cover body; the first interface disc is provided with a plurality of via holes, and the via holes in the first interface disc correspond to the opening holes connected with the pipe interface in the cover body, so that the opening and closing functions of the filter bottle are increased through tiny volume change, and the filter bottle has a relatively small volume. On the other hand, the cavity is formed between the filter layer sleeved in the filter bottle and the internal structure of the filter bottle, and the cavity is correspondingly communicated with the water inlet and outlet pipe interface on the filter bottle cover through the filter bottle interface, so that the integration of various filter functions can be realized under the small-amplitude change of the bottle diameter of the filter bottle.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to an intelligent single-stage composite integrated RO filter core multi-layer purification filter bottle assembly. Background technique [0002] With the public's pursuit of quality of life, people's requirements for drinking water quality are getting higher and higher. Therefore, as a purification device for drinking water, the water purifier can make the purified water fresher, more hygienic and safer, and is welcomed by consumers. This has further promoted the rapid development of the water purifier manufacturing industry. In order to meet the large demand of the market, how to reduce the cost of water purifier production and use is a problem that needs to be solved in the industry. [0003] Most of the water purifiers in the prior art adopt, for example, a household water purifier with enhanced bacteria control disclosed by the publication number CN208532432U (public d...
