Description

technical field [0001] The invention relates to an outdoor water intake and purification straw, which belongs to the technical field of outdoor water purification devices. Background technique [0002] In special use environments such as wilderness survival and rescue, timely access to safe and hygienic drinking water and clean domestic water is related to the safety of personal life and the quality of life of the people during disaster relief. And at present, among the above-mentioned situation, people often spend a lot of manpower and material resources and time to carry, transport a large amount of drinking water and domestic water. At the same time, we found that most of the above-mentioned situations are not lack of water resources, but lack of a portable device for purifying sewage. Due to the urgent need in this regard, life straws have appeared. [0003] Lifestraw purifies sewage (natural water) into drinking water by combining different filter materials to ensure w...

AI Technical Summary

Problems solved by technology

However, the current life straws often have a single structure and a single function, which is not enough to deal with all the problems we encounter in special environments such as survival in the wild, flood relief, and earthquake rescue.

For example, the life straw shown in the patent No. ZL204541629U provides a device for purifying sewage through physical filtration, but there are some problems such as the amount of purified water is small and cannot store water. When the distance from the next water source is far away, it loses its role as a life straw

Although the life sippy cup shown by the patent number ZL204325028U can store part of drinking water, it cannot provide a large amount of domestic water in a short period of time, and it is inconvenient to carry

Moreover, the filter material of life straws currently on the market is single and cannot be replaced, and cannot completely solve the different water pollution problems encountered by users in different regions.

In general, most of the current life straws have single functions and have shortcomings
