Description
Technical field
The utility model is related to Drinking Water Filtration technical field, referring in particular to one kind, can to filter the fields such as brook, river non-
The filter element device of the harmful substances such as bacterium, virus, heavy metal, peculiar smell, particulate matter and cold water drinking container in purified water.
Background technology
Water is Source of life, and nutrition is by each organ and skin of moisture conveying to human body, and cylinder metabolism-ure is by water
Divide and excrete, water is the most basic substance of vital sign performance.Rationally drinking-water, not only can by force body, the happy heart, increasing intelligence, may be used also
With health care, lengthen the life, beauty, toxin expelling.
One adult under normal circumstances, consumes 2~3 liters of water daily；It puts on short allowance down, at least needs 500 milliliters within one day
Water.Therefore clean water source is quite important to the life for ensureing people.
Field water mostlys come from rivers, lake, streams or other undeveloped water sources.It generally comprises a variety of visible micro-
Grain object, such as silt, mud, sundries, humic acid and tannin (coming from rotten plant) etc., allow water present different colors and
Peculiar smell.Often containing the multiple harmful substances such as various bacteria, virus, heavy metal in such water, it is non-extreme under the conditions of human body it is hard
It must not arbitrarily drink.
For field water process, country and relevant authority department are free from pathogen to the definition of clean water.Four kinds of water sources
Pathogen needs cause concern：Protozoan, bacterium, virus and many cells parasite.
Therefore how to remove pathogen, heavy metal ion, organic matter in field water etc. is the problem that we concentrate on studies.
Outdoor activities either outer suburbs tourism or field operation march, human body will consume a large amount of muscle power and moisture, constantly mend
Water-filling is divided into essential physiological behavior.But outdoor activities often face heavy burden and are not easy overweight, portable water
The problem of unsuitable excessive.Outdoor enthusiast or field army's march can often be goed deep into meagrely-populated regional or more severe on the road
Environment in, face the problem of can not getting clean water source.Therefore, directly taken to natural water resources such as mountain spring, brook, rivers
Water becomes the unique selection of many outdoor activists.
Field water is often containing harmful substances such as silt, protozoan, bacterium, virus and many cells parasites.Even
It it is believed that clean mountain spring water, looks at that limpid, mouthfeel is also cool, but also can't see just like virus, bacterium, microorganism etc., is right
The substance that human body is harmful to, it is impossible to the quality of water quality is judged only according to observation and mouthfeel.The water with pathogen is drunk, it may be to human body
Bring irreversible damage.Some mountain spring waters are phreatic waters, it is also possible to collect again after surface water infiltration soil and flow out
's.The water of earth's surface is larger by surrounding environment influence, is easily polluted by human and animal excreta, corrupt plant, contains pathogenic bacteria and parasitism
The probability of worm's ovum is larger.
Cold water filter species is various on the market at present, such as full simetryn hydrophone, purifying kettle, mainly for household application market,
Household tap water is filtered, volume is larger to be difficult to carry.And the work principle of filter that this kind of purifier uses uses nothing mostly
Woven fabric is combined with activated carbon or biological enzyme, is filtered in a manner of sieving and absorption.Due to this in-depth filtration material
Pass is irregular micropore, and filtering accuracy is difficult to ensure that aperture is larger in addition, it is difficult to by cold water bacterium, virus, a huge sum of money
The nuisance of the nominal particle sizes such as category filters out；And activated carbon or biological enzyme have superpower adsorption capacity, it can be by chemistry, pesticide in water
Organic residues, tiny ionic adsorption is waited to fall, but simultaneously also will be clean beneficial to ion remaval in water.Therefore filtering is adopted this method
Tap water, first have to the pollution level for depending on tap water transmission process, i.e. bacterium, the population size of viral group, for compared with
Small bacterium, the tap water of viral group can be described as comparatively safe drinking water, but not be the drinking water of health！Substantially less than
The requirement of direct drinking, let alone to the safety guarantee of outdoor uncertain water source filtering.Boiled drink of water is directly needed into fire
Source and heatproof container, and the new harmful substance such as incrustation scale can be generated.Also someone is come clearly using the precipitation method or direct chlorination at present
Clean water source, but pathogen can not be effectively removed, and the amount of chlorination is difficult to control, and can generate chloride chemical disinfection byproducts, is had carcinogenic
Property.Lack in the market and be suitble to what open air used with oneself, the portable tank of the fresh water in nature can be filtered.
For outdoor activist, since drinking water simply solves short-term or provisional water shortage problem, drinking water
Safety problem is matter of utmost importance, significantly larger than the health problem of water.How by particulate matter particularly bacterium, virus, organic matter etc.
It is that this patent focuses on the problem studied to have the nuisance of mortal injury to clean out to human body.
