Problems solved by technology

The processing method of the spout of the military kettle is the mold shrinking method. The diameter of the spout of the kettle made by this processing method is quite different. It is generally difficult to find two military kettles with the same size. Therefore, the seal between the filter element and the spout It is quite difficult, and when the filter element is required to be built into the kettle for easy use and portability, it is even more difficult to seal

Description

technical field [0001] The invention relates to a tablet and a filter element for preparing drinking water from inferior water sources by using a military kettle, and is used for preparing drinking water from inferior water sources, especially using a hard military kettle to prepare drinking water from polluted water sources. It belongs to the technical field of water treatment. Background technique [0002] It is an essential combat health equipment to provide drinking water disinfection medicines and instruments for field troops. At present, the military kettles equipped by the troops are aluminum hard kettles with a capacity of about one liter. The amount of water carried at a time is not enough for soldiers to drink for more than 2-3 days. Therefore, the existing military kettles are used to prepare drinking water from local water sources at any time. Water increases a soldier's combat and survivability. There are many types of wild water sources, such as diversion wat...
