Portable filter

Abstract

The invention relates to the field of water filtering equipment, in particular to a portable filter. The portable filter comprises a filtering head, wherein the filtering head is matched and connected with a water collecting bag through threads, and the water collecting bag adopts an elastic structure; the filtering head is provided with a steel wire fine mesh, filtering cotton, a ceramic filter element, a suction pipe and a screwed nipple from top to bottom sequentially, a through hole for communicating an upper end and a lower end of the filtering head is formed in the filtering head, the steel wire fine mesh is mounted at the upper end of the filtering head in a sleeving manner, the filtering cotton and the ceramic filter element are mounted in the through hole in the filtering head sequentially from top to bottom, a cavity is formed between the lower end surface of the ceramic filter element and the filtering head and provided with the suction pipe communicated with the cavity, and the suction pipe extends into the water collecting bag; the lower end of the filtering head is an internal screwed nipple and is matched and connected with the water collecting bag. The portable filter has the characteristics of filtering, portability, foldability, detachability and the like, and can meet the requirement for water taking from a water source with low water level in the field.

Description

technical field [0001] The invention relates to the field of water filtering equipment, and is a portable filter suitable for use in the field. Background technique [0002] When people are outside hiking, nasty microbes are everywhere, so we have to take water seriously. The following are the main causes of traveler's diarrhea: Bacteria 50%, such as E. coli; Viruses 15%, they are the smallest, so small that they are difficult to filter; Protozoa 5%, they are large, and they are easy to filter; Unknown 30% had unidentified specific diseases. In the wild without access to clean drinking water, you have to face these threats. [0003] If the existing filter element is fine enough, protozoa, their eggs, and bacteria can be eliminated by filtration, but it cannot eliminate viruses, because viruses are much smaller than bacteria. In this way, people still have to face a great threat. Secondly, the existing filter has a large volume and a rigid structure as a whole, which cann...

Problems solved by technology

Secondly, the existing filters are bulky, and the whole is a rigid structure, which cannot be disassembled and compressed, and is not easy to carry in the field

[0004] At the same time, facing the problem of inconvenient water fetching in the wild, such as in small pools, streams with low water levels or other places, it is not convenient to directly use water bags to fetch water at this time
