Problems solved by technology

However, the disadvantage of this water bag is that the entire forward osmosis water bag needs to be kept in a sealed and vacuum state. Once the forward osmosis water bag is torn open, the aqueous solution in it is drunk, and the air pressure in the water bag becomes normal pressure. In this way, figure 1 The disclosed forward osmosis water bag can only be used once

Abstract

The invention relates to a foldable purified water bag and belongs to the technical field of water purification. The foldable purified water bag comprises a first frame, a second frame and forward osmosis filtering membranes, wherein the forward osmosis filtering membranes are paved on the first frame and the second frame so as to form two bases of the purified water bag, one base is provided with an opening sealed by a cover, and the two bases of the purified water bag are connected together by virtue of the forward osmosis filtering membranes capable of forming a cylinder so as to form the side wall of the purified water bag. The foldable purified water bag provided by the invention can be used for repeatedly purifying water for multiple times.

Description

technical field [0001] The invention relates to a foldable water purification bag, in particular to a water bag suitable for purifying water in a field environment, and belongs to the technical field of water purification. Background technique [0002] At present, in addition to aluminum closed-mouth kettles, the kettles used by officers and soldiers also have cylindrical kettles with heat preservation function. These kettles are carried on the back or on the waist. The amount of water carried in military water bottles is limited, and clean drinking water must be replenished after use. However, when the troops are fighting in a field environment or doing emergency rescue and disaster relief, the amount of water they carry is limited, and it often happens that they cannot find a clean water source to supplement the drinking water in the military kettle. [0003] In order to be suitable for emergency needs, a kind of forward osmosis water bag disclosed in the prior art, such ...
