Abstract

An assembly filter core for a water purifier comprises a housing provided with an opening at the bottom. An inner cylinder communicated with an air-out device is arranged at the opening, a hollow fiber assembly fixed with the housing is arranged in the inner cylinder and carries out filtering though the hollow fiber ultra-filtration membrane, a water outlet is arranged at the bottom of the inner cylinder for the water-discharging after filtering though the filter materials, and a silk screen is arranged at the place corresponding to the water outlet, keeping the filter material out. Due to the filter core structure that the filter water after filtering though the filter material can flow into the inner cylinder from top to bottom, and then is discharged after filtering though the hollow fiber, the filtration effect of the assembly filter core is good. The utility model is also provided with a siphon type filter core which has the advantages of sufficient utilization of the filter material,and stable water-flowing. The arrangement of the inner cylinder and the air-out device is favorable for the discharging of the air in the filter core. In addition, the hollow fiber ultra-filtration membrane adopted can thoroughly remove the harmful substance in the water such as bacteria, macromolecule organics, etc. Thus, the quality of the discharging water can be ensured.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

First embodiment, as shown in Figure 1, this combined type filter core comprises housing 1, filtrate 2, be positioned at the filter core square 14 of filtrate top and hollow-fiber module etc., wherein square 14 contacts cooperation with housing 1 inwall, its middle part has through hole, it is latticed that cap is, and is bonded with silk screen 13 on the grid, and be equipped with the exhaust apparatus of discharging for air in the filtrate 2 on through hole.Here, this exhaust apparatus comprises net tube 12 that is located at place, through hole below and the exhaust joint 19 that is arranged in through hole again, and exhaust outlet 15 is arranged between exhaust joint 19 and the bore periphery, and the air in the filtrate 2 is discharged by this exhaust outlet 15 through the silk screen of net tube 12 sidepieces.Be provided with steam vent 17 above exhaust joint 19, steam vent 17 is provided with diaphragm 18, and this diaphragm 18 is located by a spacer 16 with ventilating structure.
