Description

Combined filter element for water purification device

technical field

The utility model relates to a combined filter element used in a water purifying device, in particular to a filter structure of the combined filter element used in a water purification barrel of the water purifying device, and belongs to the transformation technology of the combined filter element used in the water purifying device.

Background technique

The structure schematic diagram of the combined filter element of the clean water barrel of the prior art is shown in Figure 1, 2, and the internal filter material and parts of its combined filter element structure are more, specifically comprise filter material box 10 and filter material cover 20, on the filter material cover 20 The floating ball 30 and the exhaust cap 40 are set, and the filter material cover is welded and fixed on the filter material box, and the filter material includes resin particles 50 , silver-loaded activated carbon particles 60 and activated carbon particles 70 . In order to prevent the mixing of each particle, cover plates 101, 102, 103 in three filter material boxes are set in the filter material box 10, and nylon mesh 80 is set on the middle cover plates 102, 103 respectively, and below the middle cover plate 101 Set nylon mesh 80. In order to achieve a better filtering effect, activated carbon non-woven fabrics 90 are added between the nylon mesh 80 and the activated carbon particles 70 , and between the resin particles 50 and the inner bottom surface of the filter material box 10 .

When the filter element is working, the unfiltered raw water first enters the filter material box 10 through the water hole at the bottom of the filter material box, passes through resin particles 50, silver-loaded activated carbon particles 60 and activated carbon particles 70 in turn, and finally passes through the filter material box. The water hole enters the filter element of the next stage. At the same time, when the air pressure in the filter box increases, the floating ball on the top of the filter cover can be pushed open to discharge from the air vent on the top of the filter box. When the air pressure in the filter box decreases, the floating ball will press the vent hole under the action of water pressure to prevent raw water from entering the filter element from the vent hole.

The combined filter element of the water purification device in the prior art has a complex structure and many internal parts, which makes the assembly efficiency low; at the same time, during the transportation process, because the activated carbon particles will collide with each other, a lot of fine activated carbon powder will be produced inside the filter element. When it is used for the first time, "black water" containing activated carbon powder will flow out from the filter element, which will affect the perception of purified water; and because there are gaps between activated carbon particles, its filtering effect cannot be achieved at its best.
