Water purifier with ring-shaped synthesis filter element

Abstract

The invention discloses a water purifier with a ring-shaped synthesis filter element. The water purifier comprises a waterway board with a preset pipeline, wherein a waterway interface is arranged onthe waterway board, and is communicated with a pipeline in the waterway board; at least two groups of filter assemblies which are arranged in a concentric mode are arranged on the waterway board; thefilter assemblies comprise a first filter assembly on the center position, and at least one group of second filter assemblies which sleeve the outside of the first filter assembly; the second filter assemblies are of cylindrical structures; the first filter assembly and the second filter assemblies are independently arranged and are blocked on the same waterway interface; at least two connecting holes which are formed in the concentric mode are formed in the waterway interface; and each connecting hole separately is communicated with each filter assembly. Multiple groups of filter elements aremanufactured into the synthesis filter element of a sleeve ring, so that the diameters of the filter elements are obviously increased, and the filter areas of the filter elements are further increased, and therefore, the service life of the front filter element is greatly prolonged; and meanwhile, quantity of filter bottles in the water purifier is reduced, and the water leakage risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, in particular to a water purifier with an annular synthetic filter element. Background technique [0002] Nowadays, the pollution of water resources is becoming more and more serious, and the problem of urban water safety is particularly serious. In view of the secondary pollution of tap water and the presence of harmful substances in tap water caused by raw water pollution, more and more water purifiers are used. After the water purifier is used for a period of time, the pipes and equipment will cause secondary pollution, and the filter element is the core component of the water purifier. The state of the reverse osmosis filter element directly affects the quality of the effluent water, so regular replacement is essential. In order to ensure the water purification effect and prevent secondary pollution, the water purifier should replace the filter element on time according t...

Problems solved by technology

However, the service life of pre-filter elements such as PP cotton layer and activated carbon layer in the composite filter element is not the same as that of RO membrane. - ranging from 36 months

This makes the overall service life of the composite filter element to be determined according to the use status of the PP cotton. Often at this time, the RO membrane or ultrafiltration membrane is far from the replacement deadline, but when replacing the filter element, only the entire filter element can be replaced. Reduce the use value of the filter element
