Portable hand-pressing ultrafiltration membrane water-purification cup

Abstract

The invention discloses a portable ultrafiltration membrane water-purification cup. The ultrafiltration membrane water-purification cup is composed of a cup cover, a cup body, a filter element cylinder and a pressurization device. The cup cover is provided with a water inlet and is in rotary joint with the cup body through screw threads; the cup body is composed of an inner cavity and a suction pipe, the inner cavity is divided into an original water layer and a pure water layer, a water permeable hole in the bottom separator plate of the original water layer holds the filter element cylinder, the filter element cylinder communicates the original water layer with the pure water layer, the suction pipe is communicated with the cup cover through the separator plate, and the suction pipe is in seal connection with the separator plate; the filter element cylinder is composed of active carbon and a cylindrical ultrafiltration membrane assembly, the filter element cylinder can be cleaned and replaced easily, the active carbon is fixed by a stainless steel filter screen, and the ultrafiltration membrane assembly is arranged under the active carbon; and the pressurization device is a hand-pressing type air bag. According to the invention, the hand-pressing type air bag is used for pressurization, original water passes through the filter element, and the percolate is drinkable.

Description

technical field [0001] The invention relates to ultrafiltration water purification technology, in particular to a hand-pressed ultrafiltration membrane water purification cup, which can be applied to the preparation of outdoor drinking water for one or two people. Background technique [0002] With the acceleration of the pace of modern life and the change of lifestyle, more and more people are keen on outdoor recreation, hunting, adventure, etc. They need clean water to quench their thirst when they go out, but the finished clean water is expensive and heavy . However, river water, lake water, and spring water in the wild are not purified and should not be drunk directly. Therefore research a kind of portable wild water purification cup is particularly necessary. The field water purification cup reduces the burden of people carrying drinking water, and can purify river water, lake water, and spring water anytime and anywhere in the field to ensure the safety of drinking w...
