AI Technical Summary

Problems solved by technology

When the flow medium is filtered by the filter unit, the flow medium to be filtered is consumed or used many times in a day, the period of time for clogging the filter cartridge will be relatively short
The cost of this cumulative replacement will be unaffordable for many
[0005] Applicants have been attempting to flush the filter cartridges of some known filter devices, the success of which has been limited by the inability to remove most of the impurities trapped in the filter material

Embodiment Construction

[0037] Referring to Fig. 1, Fig. 1 shows a section of filtering device 10 of the present invention. The device 10 is for filtering water, which is connected to a water tap 100 . The device 10 has a stepped cylindrical hollow body member 12 having a larger portion 14 and a smaller portion 16 . The body member 12 is adapted for water to flow into the open end (the inlet end) of the larger portion 14 and out of the device 10 through the open end (the outlet end) of the smaller portion 16 .

[0038] A larger portion 14 at the inlet end has external threads for attachment of a cover member 18 . The cover member 18 has a disc-shaped part 20 , a rim part 22 extending axially inwardly from the part 20 , a neck part 24 and a water-guiding part 26 . The edge part 22 is internally threaded for screwing onto the larger part 14 and the neck part has a seat 25 (see Figure 3) for receiving a seal.

[0039] The neck member 24 is also threaded for connection with a threaded fitting 28 which...

Abstract

A filter (10) for filtrating special impurities contained in fluid medium. The filter (10) comprises a hollow member (12) with a first openings and a second openings facing the first one. A lid member (18) with a through hole is removable fixed to the first openings and the fluid medium enters into the chamber of the hollow member (12) via the through hole. An carding and non-woven textile fibres is arranged in the chamber and the route of the fluid chamber to trap a majority of impurities. The fluid medium substantially free of impurities passes through the second openings and flows out the hollow member (12).

Description

technical field [0001] The present invention relates to a filter device for filtering a flowing medium, in particular, but not limited to, a filter device for filtering water from a tap. Background technique [0002] Flow media such as water, fuel, and various gases usually contain special impurities, and the filter device is used to filter these impurities so that the flow media for consumption or use are basically free of impurities. [0003] Existing filtering device usually has a cylinder with built-in filter material, and the configuration of the cylinder can make the flow medium to be filtered permeably pass through the filter material before passing through the filter device, and when flowing through the filter material, more than a certain amount of water is retained in the filter material. A special impurity of one size. So that the medium passing through the filter material does not contain impurities larger than the above-mentioned size. [0004] Over time, thes...
