As an indispensable item in our daily life, water bottles can help us replenish water in a timely manner. Especially when we go out to climb mountains, the advantages of carrying water bottles with us are reflected. We can climb mountains with confidence, and can replenish water in a timely manner when we are tired. However, we all know that water bottles are also divided into civilian and military ones. We know about civilian ones, but we rarely know about military ones, What is the "internal structure" of military water bottles and what are the secrets? The answer may not be known by veterans.

As a carry on item for soldiers, the importance of military water bottles for soldiers is self-evident. Soldiers also need to replenish water. However, the military water bottles we usually see are basically of the same style. They are either black or green, and rarely other colors. In fact, military water bottles are different from ordinary water bottles. Military water bottles emphasize concealment, durability and functionality. Let's take a closer look.

First of all, let's take a look at the internal structure of military kettles: after a hundred years of development, military kettles in the world now have more than just water filling functions. Many armies will transform the internal structure of kettles to enable them to filter and maintain temperature. These two points are very important. Our military kettles are generally made of thickened stainless steel and contain filtering devices, It can filter water with impurities directly in extreme wild living environment. However, in peacetime, many veterans may not know the role of the kettle.

Secondly, different regions have different requirements for water kettles. For example, in those cold plateau regions, the requirements for the heat preservation effect of water kettles are very strict. Generally, the water kettles used by our army on the plateau are vacuum double-layer heat preservation water kettles, which can play a very good role in heat preservation. In a low temperature of minus ten degrees centigrade, hot water can still maintain the temperature in the kettle for a day, and cold water stored in the kettle will not freeze because of the external environment, Instead, keep the original temperature for a long time. This is very important for soldiers in severe cold areas, because traditional water bottles are not very effective in heat preservation under such extreme conditions. The hot water will be cold soon. If they stay outside for a long time, the water in the water bottles will even freeze. The emergence of high-tech water bottles has solved the urgent needs of soldiers. The powerful heat preservation effect allows soldiers to perform tasks outside more comfortably.

In a word, many advanced military kettles now generally have filtering devices inside, and the result is double-layer vacuum insulation, which can meet the use in extreme environments. Moreover, military kettles are also very durable. Some people even say that they can be used to block bullets at critical moments. Although it is just a joke, it also shows the powerful role of modern military kettles. Have you seen what your friends have learned.
