A water purification filter that realizes water inlet at both ends of the membrane module through one-end contact

Abstract

The present invention relates to a water purification filter capable of achieving water inflow at two ends of membrane module through contact at one end. The water purification filter comprises a filter cartridge and a plate rib, wherein a housing is arranged on the inner side of the filter cartridge; a upper end cover and a lower end cover are arranged in the housing; a flow measurement membrane is arranged between the lower end cover and the upper end cover; a center tube is arranged at the center part of the flow measurement membrane; an upper center tube and a lower center tube are arranged on the upper side of the center tube; an inner tube is arranged inside the center tube; an eccentric tube is arranged on the right side of the lower center tube; a water through hole is formed in the right side of the eccentric tube; a raw water flow path is arranged at the middle part of the upper center tube; a pus flow path is arranged on the two sides of the upper center tube; a flow divider is arranged on the upper side of the upper end cover; a housing cap is arranged on the upper side of the filter cartridge; a machine head module is arranged on the upper side of the housing cap; a first hinge is arranged on the left side of a rotary valve; a plug is arranged between the first hinge and the rotary valve; a spring is arranged on the left side of the plug; and a second hinge is arranged between the machine head module and a hinge adapter.

Description

technical field [0001] The invention relates to the technical field of application of water-saving filter elements, in particular to a water-saving filter element. Background technique [0002] Water is an important part of the human body. The water in the human body accounts for about 50% of the body weight of an adult. The average daily water consumption of a normal person is 2000-2500ml, most of which are obtained by water diversion. Because the existing tap water contains chlorine, bleaching powder , bacteria, etc. are suitable for direct drinking, and the price of bottled mineral water is high, which is not suitable for daily use. Therefore, a simple-structured, economical and environmentally friendly water purification filter element has become an important device to improve the quality of people's daily water.

Problems solved by technology

[0002] Water is an important part of the human body. The water in the human body accounts for about 50% of the body weight of an adult. The average daily water consumption of a normal person is 2000-2500ml, most of which are obtained by water diversion. Because the existing tap water contains chlorine, bleaching powder , bacteria, etc. are suitable for direct drinking, and the price of bottled mineral water is high, which is not suitable for daily use. Therefore, a water purification filter element with a simple structure, economical and environmental protection has become an important equipment to improve the quality of people's daily water.

[0003] However, the existing water-saving filter elements generally use ordinary reverse osmosis membranes, and the application of side flow reverse osmosis membranes is relatively seldom. In addition, water enters both ends of the filter element, and it is inconvenient to replace the filter element; the present invention is based on the deficiencies of the prior art.
