Double-water-channel water purification tap combination filter element

Abstract

The invention provides a double-water-channel water purification tap combination filter element. After being installed to a purpose-made water tap, the filter element has double water channels, so the water without needs for filtration and water in demands for filtration independently exist in the two channels, thereby ensuring that the user can use the filter element at low cost. The filter element comprises a central tube, wherein the inner cavity of the central tube is a direct-flow water channel; a PP (polypropylene) filter bowl is sheathed on one end of the central tube; the rim of the PP filter bowl is arranged towards the other end of the central tube; the inner wall of the PP filter bowl is provided with a PP cotton prefilter piece; the inner wall of the rim of the PP filter bowl is connected with one end of an ultrafiltration membrane shell in a sealing mode; the upper part of the ultrafiltration membrane shell is provided with a sintered activated carbon rod; the sintered activated carbon rod is provided with a central inner hole; a connecting cover is arranged between the ultrafiltration membrane shell and the sintered activated carbon rod; ultrafiltration membrane yarn is arranged in the ultrafiltration membrane shell; and a water outlet of the inner cavity of the ultrafiltration membrane shell communicates with a water inlet of the connecting cover.

Description

technical field [0001] The invention relates to the technical field of water filter core structures, in particular to a combined filter core for a dual-channel water purification faucet. Background technique [0002] Drinking water is an indispensable element for human survival, and water is also an important medium for spreading diseases, which is closely related to people's daily life. Residents living in the city, the source of their drinking water is centralized supply by the water company. Although the water produced by the waterworks meets the drinking standards, the tap water in the pipe network, due to long-distance pipeline transportation, will cause the pipe network to become obsolete due to long-term use, causing harmful substances such as rust to be produced inside the pipe network. In addition, the current method of using high and low pools for secondary water supply is generally used. The water tanks of high-rise buildings in cities and the reservoirs of build...

Problems solved by technology

[0003] The filter elements currently on the market are all single-channel structures. All water sources entering the channel need to be filtered through the filter element and then flow out. In the actual use of people, part of the water does not need to be filtered before use. For this reason, all existing water is passed through. The filter element is used after filtering, so that the service life of the filter components at all levels is relatively shortened, and the use cost of the filter element is relatively high.
