Problems solved by technology

[0002] The existing household water purifier filtration system generally includes a coarse filtration system and a fine filtration system. The filter materials of the coarse filtration system include PP cotton, activated carbon, ceramics, etc., which are respectively packed in a plastic cylinder; the fine filtration system is mainly RO membrane reverse osmosis The membrane is also installed in a plastic cylinder, that is, all kinds of filter materials are individually packaged through the plastic cylinder, and then the filter elements of all levels are connected in series with quick connectors and PE pipes. This traditional combination of filter elements not only occupies the inside of the machine Large space, many consumables, cumbersome production process, many interfaces, high risk of water leakage, high production cost and after-sales maintenance cost

Embodiment 1

[0018] As shown in Figure 1, a composite filter element for a pure water machine includes a plastic filter shell 1, a filter cover 2, and a filter material with a coarse filtration system that is packaged in the filter shell 1 sequentially from the outside to the inside. And the RO membrane filter material 5 of the fine filtration system, the filter housing 1 is cylindrical, and the bottom of the filter housing 1 is provided with a source water inlet 1.1, a concentrated water outlet 1.3 and a pure water outlet 1.2 connected with the corresponding connecting pipe , wherein the pure water outlet 1.2 is set at the bottom center of the filter shell 1, the source water inlet 1.1 is set at one side of the bottom of the filter shell 1, and the concentrated water outlet 1.3 is set at the pure water outlet 1.2 and the source water inlet 1.1; a head cover 6 is fixedly connected to the inner wall of the bottom of the filter housing, and the lower end of the head cover is provided with a U...

Embodiment 2

[0022] The difference from Example 1 is that the filter material of the coarse filtration system is a two-layer combined structure of PP cotton 3 and activated carbon fiber from outside to inside.

Embodiment 3

[0024] The difference from Example 1 is that the filter material of the coarse filtration system is a three-layer combination structure of outer layer PP cotton, sintered activated carbon, and inner layer PP cotton from outside to inside, wherein the thickness of the outer layer PP cotton is 10um, and the inner layer PP cotton The thickness of the cotton is 5um.

[0025] The present invention only describes in detail the structure in which the filter material of the coarse filtration system and the RO membrane filter material of the fine filtration system are encased and packaged sequentially from the outside to the inside. Those skilled in the art can easily make the filter material of the coarse filtration system Arranged in reverse with the RO membrane filter material of the fine filtration system, a similar effect can also be obtained.

Abstract

A composite filter core of a water purifier comprises a filter shell, a filter material of a coarse filter system and an RO membrane filter material of a fine filter system are sleeved in the filter shell, and the bottom of the filter shell is provided with a source water inlet communicated with a corresponding adaptor, a concentrated water outlet and a purified water outlet. All filter materials are combined and packaged in a cylinder, so the composite filter core has the advantages of simple and novel structure, small occupied space, low cost, simple production technology, reliable seal performance, and convenient maintenance and replacement.

Description

technical field [0001] The invention relates to the field of pure water machine manufacturing, in particular to a composite filter element for a pure water machine with small footprint, low cost and good sealing performance. Background technique [0002] The existing household water purifier filtration system generally includes a coarse filtration system and a fine filtration system. The filter materials of the coarse filtration system include PP cotton, activated carbon, ceramics, etc., which are respectively packed in a plastic cylinder; the fine filtration system is mainly RO membrane reverse osmosis The membrane is also installed in a plastic cylinder, that is, all kinds of filter materials are individually packaged through the plastic cylinder, and then the filter elements of all levels are connected in series with quick connectors and PE pipes. This traditional combination of filter elements not only occupies the inside of the machine The space is large, the consumable...
