[0002] With the diversification of outdoor sports, emergency rescue, and travel scenarios, the demand for portable drinking water devices is increasing. Traditional water bags are mostly made of flexible materials, which are foldable and lightweight, effectively saving storage space.

[0003] A search revealed a utility model patent for a foldable water bag with a valve-type switch, authorized by publication number CN 214297197 U. This patent controls water flow by using a water bag cap with a faucet valve and employs a drawstring for carrying and repositioning, improving ease of use. However, this design lacks water filtration functionality, failing to meet the water purification needs of outdoor scenarios. Furthermore, the water bag itself is prone to flattening during drainage due to reduced internal air pressure, leading to poor water flow and affecting the structural stability of the water bag.

[0004] Therefore, a filter-type foldable water bag is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filter-type folded water bag to solve the problems mentioned in the background art.
