Portable intermittent water supply purifier

Abstract

The invention relates to the water treatment industry, particularly to the aspect of depth filtration and purification of field drinking water. The invention discloses a portable intermittent water supply purifier, which comprises a water pumping cylinder, a first water inlet one-way valve, a second water inlet one-way valve, a movable filter element device arranged in two-way mode and an upper stand and a lower stand which are connected and fit with the movable filter element device, wherein a filter element water inlet channel and a filter element water outlet channel which are mutually independent are formed by a sealing piece among a port of the movable filter element and the upper stand and the lower stand; and the water inlet channel of the lower stand is connected with the water pumping cylinder, and the first water inlet one-way valve and the second water inlet one-way valve. The portable intermittent water supply purifier has the advantages of simple structure, high filtrationlevel, easy backwashing, good effect, diversified and pre-treatable water taking, strong environmental adaptability and long service life of the filter element; besides, the adoption of pre-filtration can effectively filter large-sized suspension pollutants such as algaes, insects, dust and the like, colloids and particles, and keep the inside of a cavity of the water pumping cylinder clean to relieve the burden of fine filtration. A user can wash and reuse the portable intermittent water supply purifier independently.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of outdoor drinking water. Background technique [0002] At present, the use of portable water purifiers has been popularized to a certain extent in China. In the wild environment, when lake water, rainwater, and river water are directly filtered into drinking water, a portable water purifier is used to filter impurities in the water in depth, which better protects the health of users. However, along with the gradual popularization of portable water purifiers, their defects and deficiencies in application have gradually been exposed. Due to the diversity and unpredictability of the natural environment in the wild, as well as suspended pollutants such as bacteria, algae, insects, and dust, as well as particles and colloids in the water, the water quality index is often lower than that of tap water, making filter elements with higher f...

AI Technical Summary

Problems solved by technology

However, with the gradual popularization of portable water purifiers, their defects and deficiencies in application have gradually been exposed.

Due to the diversity and unpredictability of the natural environment in the wild, as well as suspended pollutants such as bacteria, algae, insects, and dust, as well as particles and colloids in the water, the water quality index is often lower than that of tap water, making filter elements with high filtration accuracy very difficult. Easy to clog or even fail

Moreover, as more and more impurities are intercepted by the filter element, the impurities of the filter element will often become a new source of "pollution", and the filter element needs to be replaced, resulting in a very short life of the filter element.

In addition, because the field environment lacks the power required for using water purifiers, microfiltration water purifiers that do not require power often cannot guarantee the safety of direct drinking water, so that they cannot be used in environments where natural disasters such as earthquakes, floods, and droughts occur

The above-mentioned defects and deficiencies affect the popularization of portable water purifiers
