Description

Domestic water purifier with hollow fiber nanofiltration membrane Technical Field The utility model relates to the technical field of water purifying devices, in particular to a hollow fiber nanofiltration membrane household water purifying device. Background With the development of industry and cities, water source safety has been paid attention to, and for water resource end users, water pollution phenomenon caused by primary water supply pipelines or secondary water supply is increasing, so that household water purifying devices are generated, and main stream water purifying devices in the market can be divided into pressurized water purifying and normal pressure water purifying according to the presence or absence of a pump body. At present, most of household water purifying devices use RO reverse osmosis membrane water purifiers, because the effluent flow is smaller, a matched storage tank is needed, and the use space is increased. Therefore, another pressurized water purifying device is provided, the nanofiltration membrane water purifier does not need a storage tank, but in the use process, the filter element is inconvenient to clean, so that the service life of the filter element is shorter. Disclosure of utility model The utility model mainly aims to provide a hollow fiber nanofiltration membrane household water purification device so as to solve the problem that a filter element in the prior art is inconvenient to clean. In order to solve the problems, the technical scheme is that the hollow fiber nanofiltration membrane household water purifying device is arranged between a household water inlet pipe and a filtering tap and between an unfiltered tap and comprises a filter, wherein the filter comprises a water inlet end, a filtered water outlet end and a non-filtered water outlet end, the household water inlet pipe is respectively communicated with the water inlet end and the unfiltered tap of the filter through pipelines, a pump body is arranged between the household water inlet pipe and the water inlet end of the filter, a valve is arranged between the household water inlet pipe and the unfiltered tap, the non-filtered water outlet end of the filter is communicated with the pipeline between the valve and the unfiltered tap, and the filtered water outlet end is communicated with the filtered water outlet tap. Further, the water purifying device further comprises a frame body assembly, the frame body assembly comprises a U-shaped frame and a supporting plate fixedly arranged in the U-shaped frame, and the filter is arranged on the supporting plate. Further, the backup pad is rectangular frame structure, the relative both sides of backup pad be equipped with respectively with the draw-in groove of filter outer wall looks adaptation, the axial both ends accommodation of filter is in the draw-in groove. Further, a plurality of through holes are respectively formed in the U-shaped frames at four corners of the supporting plate, the through holes are uniformly distributed along the height direction of the U-shaped frames, a plurality of first bolts are arranged on the U-shaped frames, and the first bolts penetrate through the corresponding through holes and are fixedly connected with the supporting plate. Furthermore, a connecting plate is fixedly arranged on one side of the pump body, and the connecting plate is fixedly connected with the supporting plate through a buffer assembly. Further, the four corners of connecting plate department is equipped with the perforation respectively, buffer unit includes four axial link up rubber piece and four second bolts, four the rubber piece wears to establish respectively four in the perforation, the both ends of rubber piece are located respectively the fenestrate outside, and the external diameter at the both ends of rubber piece is greater than the fenestrate internal diameter, four the second bolt passes respectively four the rubber piece with connecting plate fixed connection.
