Convenient water-saving all-composite nano-filtration and reverse osmosis water purifier

Abstract

The invention relates to a convenient water-saving all-composite nano-filtration and reverse osmosis water purifier. The convenient water-saving all-composite nano-filtration and reverse osmosis water purifier comprises a shell, a filter element and a micro booster pump, wherein a clean water outlet nozzle is arranged on the shell; the filter element and the micro booster pump are arranged in the shell; the filter element is a composite filter element; the composite filter element adopts a cylindrical and radial multi-layer composite structure; a filter element seat is arranged in the shell; the composite filter element is arranged on the filter element seat in the shell; a space is reserved in the outer wall of the composite filter element to form a water inlet cavity; a water outlet cavity is separated from the water inlet cavity by a filter layer of the composite filter element; a water inlet connector and a washing water connector are also arranged on the shell. According to the convenient water-saving all-composite nano-filtration and reverse osmosis water purifier, the composite filter element with a multi-layer filter layer is arranged in the shell, so that the structure is compact, the volume is small, the water purifier is mounted at the required placed and is mounted without help of professionals; meanwhile, the washing water connector is arranged, so that waste water can be recovered and recycled to fulfill the aim of saving water.

Description

technical field [0001] The invention relates to the field of household drinking water purification, in particular to a convenient water-saving full-composite nanofiltration and reverse osmosis water purifier. Background technique [0002] Existing household quality-separating water supply machine is a membrane type reverse osmosis treatment terminal water purification device that carries out secondary deep purification treatment to tap water, and provides drinking pure water to people. The quality water supply machine is usually equipped with a water inlet ball valve, a booster pump, a pressure storage tank, an outlet faucet and several stages of filters, such as polypropylene filters, granular activated carbon filters, extruded activated carbon rod filters, reverse osmosis or nanofiltration Filters and electrical control parts, each filter is independent, electrical control parts (including low pressure switch, high pressure switch, water inlet solenoid valve, flushing sole...

AI Technical Summary

Problems solved by technology

The quality water supply machine is usually equipped with a water inlet ball valve, a booster pump, a pressure storage tank, an outlet faucet and several stages of filters, such as polypropylene filters, granular activated carbon filters, extruded activated carbon rod filters, reverse osmosis or nanofiltration Filters and electrical control parts, each filter is independent, electrical control parts (including low pressure switch, high pressure switch, water inlet solenoid valve, flushing solenoid valve, booster pump and transformer, waste water proportioner, etc.) and filter elements Interlaced assembly, they are connected with each other by multi-section pipes and pipe joints according to the filtration process, through different collocations to form multi-stage water purifiers, ultrafiltration water purifiers or reverse osmosis pure water machines, so there are many pipes and pipe joints, The structure is loose and complex, and the overall size is too large. The equipment can only be hidden under the sink, and professional technicians need to adjust the pipeline to complete the installation and commissioning, which is one of the biggest bottlenecks in the market popularization of this industry; in addition, household nanofiltration (Reverse osmosis) water purification equipment requires an additional 50-70% of flushing water while producing safe drinking water. In the existing technical equipment, these flushing water are all discharged from the floor drain, resulting in extreme water resources. big waste
