An easy-to-clean water purification straw

Abstract

The invention discloses a water purification suction pipe convenient to clean. The water purification pipe convenient to clean comprises a suction pipe body, a filter screen, a gravel layer, a ceramic membrane, activated carbon, a filter element, a flexible pipe, a spring package, an extrusion plate and a pipe cap. The filter screen, the gravel layer, the ceramic membrane, the activated carbon and the filter element are sequentially arranged in an inner cavity of the suction pipe body from bottom to top. The rubber flexible pipe is arranged above the filter element, and a water sucking device is arranged in the rubber flexible pipe. Compared with the prior art, the water purification suction pipe is convenient to clean and solves the problem that the purification effect becomes bad after an existing water purification suction pipe is used for a long time, the water purification suction pipe convenient to clean sucks purified water into the pipe by extruding the water sucking device and then sprays the water, by means of repeated operation, impurities in a filtering device are sprayed out along with the purified water, cleaning is convenient, the cleaning effect is good, and the service life of the water purification suction pipe is prolonged.

Description

technical field [0001] The invention relates to a straw, in particular to a water purification straw which is easy to clean. Background technique [0002] The water purification straw is actually a plastic tube with a length of 25 cm and a diameter of 29 mm, which contains 7 kinds of filters, including mesh wire with a mesh diameter of 6 microns (the diameter of human hair is 50-100 microns), and activated carbon and iodine resin. First, the two-layer silk filter first filters out the dirty things, and then the iodine-containing resin can kill 99.3% of bacteria and viruses; finally, the activated carbon can capture the bacteria and viruses that slip through the net to ensure the purity of the water (up to lg7~lg8, cleaner than tap water in many advanced countries). Therefore, many kinds of dirty water can be filtered and disinfected into drinking water quality (many toxic substances such as heavy metals and chemicals cannot be filtered). [0003] Although the existing wat...

AI Technical Summary

Problems solved by technology

[0003] Although the existing water purification straw has a good water purification effect, after a long time of use, the impurities filtered out of the water will slowly accumulate in the filter device of the water purification straw, thereby making the filtering effect worse, and the filtered water is also Not up to the drinking standard, although the filter element and activated carbon and other filter devices can be replaced or cleaned again, but the process is troublesome and the filter element and activated carbon that need to be replaced also need to be consumed for the second time
