Description

A filter element with sterilizing function

technical field

The utility model relates to a filter device, in particular to a filter core.

Background technique

Due to the presence of microorganisms and other harmful substances in natural water sources, most of the water cannot be directly drunk. The natural water source cannot be directly drunk, which has always been an important problem that plagues people's survival and life. Especially in military field operations, field exploration, navigation, and outdoor camping activities, people have always been troubled by natural water sources that cannot be directly drunk.

People generally use the following methods to deal with water problems:

1. Carry enough drinking water with you. This method is often used in army field operations and when people are camping. For people, this method has a heavy load, the drinking water cannot be regenerated, and the amount of drinking water is limited. The problems referred to above have brought a lot of inconvenience to the army in the field, campers etc.

Two, the water in nature is boiled in the wild. This method is often used when the army is in the field for a long time and when people are camping for a long time. This method has high requirements on the quality of natural water sources, requires a fire source, takes a long time, is inconvenient to operate, and is limited by various conditions. The problems referred to above have brought a lot of inconvenience to the army in the field, campers etc.

3. Use RO membrane to make water. Because this method requires a power supply and huge equipment, it is difficult to carry, and it cannot be used basically when the army is in the field and people are camping.

4. Use a portable direct-drinking kettle. The direct drinking kettle has low requirements on the quality of natural water sources, is light in weight, and has a large amount of water production. But existing direct-drinking kettles still have relatively high requirements on the quality of natural water sources, and cannot be adapted to harsh environments.
