Composite filter element and adapter thereof

Abstract

The invention discloses a composite filter element and an adapter thereof. The composite filter element comprises a filter element housing body comprising a filter element housing and a filter element housing cover, wherein the filter element housing body is internally provided with a PP (Propene Polymer) cotton filter element and an active carbon filter element; a connection gland is spaced between the PP cotton filter element and the activated carbon filter element; the PP cotton filter element is clamped and sleeved with a PP cotton head; the PP cotton head is connected with a filter element divider provided with a water inlet sub-channel and a water outlet sub-channel; a location support is integrally arranged on a bottom wall of the filter element housing body; a partition is arranged on the location support in a seating manner, and forms a purified water chamber with the bottom wall of the filter element housing body; a purified water conduit for communicating the water outlet sub-channel with the purified water chamber is arranged in the centers of the PP cotton filter element and the activated carbon filter element in a penetrating manner; the periphery surface of the connection gland and an internal wall of the filter element housing body are subjected to liquid sealing and matched with the PP cotton head and the PP cotton filter element to form a water inlet chamber and a primary filter chamber that are communicated with the water inlet sub-channel; the filter element housing cover is provided with a self-closing filter element connection seat provided with a water inlet connector and a water outlet connector; and the water inlet connector and the water outlet connector are in ejection connection with and are communicated with the water inlet sub-channel and the water outlet sub-channel respectively after opening.

Description

technical field [0001] The invention relates to a water purifying device, in particular to a water purifying filter element used for filtering raw water in the water purifying device, in particular to a composite filter element and its socket. Background technique [0002] Water purification equipment is mainly to filter and purify raw water to remove harmful substances such as suspended solids, sediment, rust, residual chlorine, abnormal color and odor in raw water, so as to produce high-quality drinking water that meets human health standards. Water purification equipment often has a set of combined filtration devices for filtering raw water, and the filtration level is improved by increasing the number of filtration stages. In the prior art, when the PP cotton filter element and the activated carbon filter element are used at the same time, the two filter elements are generally used in series.

AI Technical Summary

Problems solved by technology

In the prior art, when the PP cotton filter element and the activated carbon filter element are used at the same time, two filter elements are generally used in series. The connection and installation of the two filter elements in series is not only complicated to connect and install, but also takes up a large space and is difficult to miniaturize

At present, there are also two filter elements that are combined together, that is, PP cotton is combined on the outer layer of activated carbon to make a composite filter element. The manufacturing process of this composite filter element is complicated and the diameter is large, and it is also difficult to miniaturize.
