Portable water purifier {Portable water purifier}

The present invention relates to a portable water purifier.

In general, environmental pollution is progressing with the development of industrialization, and water pollution is also increasing as an example of such environmental pollution.

In addition, most facilities are supplied with purified tap water through water purification facilities, but distrust of tap water is increasing as environmental pollution increases.

In addition, recently, along with the leisure craze, cases of drinking natural water such as mineral water, underground water, or bedrock water are increasing when going out outdoors, but the stability of such natural water cannot be guaranteed.

Accordingly, there is a demand for the development of a portable water purifier that allows a user to purify water while carrying it conveniently.

However, since conventional water purifiers filter water in a natural filtration method through gravity or purify water by an electric device, there is a problem in that they cannot respond in various ways according to water intake sources.
