Composite filtering type filtering bottle

Abstract

The invention relates to a composite filtration filter flask, which is technically characterized in that (1) a water-resisting sleeve is coaxially arranged at the lower end of a top cap in an outer sleeve and the lower end of a central tube of a reverse osmosis membrane; the upper end of the water-resisting sleeve and the lower end of the top cap are installed in a threaded meshing mode, the lower end of the water-resisting sleeve and the central tube are installed in a sealing mode, and a water inlet channel is formed between the water-resisting sleeve and the reverse osmosis membrane; and (2) a water filtration sleeve and a water purifying sleeve are coaxially arranged in sequence between the water-resisting sleeve and the outer sleeve, and various filtering materials are filled between the water filtration sleeve and the water purifying sleeve; and the lower end of the purifying sleeve is a blind hole casing sleeve, and PP filtration cotton is arranged between the blind hole casing sleeve and the water purified sleeve in the radial direction. The composite filtration filter flask has the advantages of scientific structure, reasonable design, small volume, beautiful appearance, and practical use, integrates the reverse osmosis membrane and various filtering materials into a whole, and is a technical invention with higher technology innovation.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a composite filter type filter bottle. Background technique [0002] In order to ensure the water purification effect, the pure water machines on the market use a variety of filter materials and multi-stage filtration methods to filter out impurities and dirt to ensure the water purification effect. At present, most of the filter materials use reverse osmosis membrane, post activated carbon and PP cotton, at least three filter methods (3 filter bottles, mostly PP+activated carbon, reverse osmosis membrane, post activated carbon), and reverse osmosis membrane and post activated carbon There are at least 5 water inlets and outlets. The disadvantages of this structural method are: 1. Too many filter bottles lead to a large volume of the pure water machine, which takes up a lot of space; 2. The structure is complicated and messy, and the appearance is not beautiful; 3. There are many ...

Problems solved by technology

The disadvantages of this structural method are: 1. Too many filter bottles lead to a large volume of the pure water machine, which takes up a lot of space; 2. The structure is complicated and messy, and the appearance is not beautiful; 3. There are many components, which are difficult to install and maintain. High cost; 4. The structure of multiple filter bottles results in more water inlets and outlets, which is very prone to water leakage
