Description

Business type boiling water water purifying cup

Technical field

The utility model is related to water purifying cup technical fields, refer in particular to a kind of business type boiling water water purifying cup.

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 strong body, the happy heart, increase intelligence, may be used also With health care, lengthen the life, beauty, toxin expelling.

Boil rear natural cooling plain boiled water have boost metabolism, convey nutrition, cleaning internal organ, diuresis defaecation, increasing The effects that strong immunity of organisms.Plain boiled water kills pathogenic bacteria during boiling, and remaining calcium, magnesium, phosphorus etc. has human body The macroelement and trace element of benefit.Meanwhile it has larger affinity with the hydrone in vivo biodistribution cell, readily penetrates through Cell membrane enters intracellular.So plain boiled water is the optimal selection of people.But water is during heating because zwitterion combines Generate calcium carbonate, magnesium carbonate, and these calcium salts wrapped up in mutual polymerization process be not engaged in the various heavy of reaction from Son and worm's ovum, bacterium corpse etc., these condensation products general name incrustation scales, and heavy metal ion and worm's ovum, bacterium corpse etc. are to human body Injury is the largest.Therefore the water after boiling is inevitably present safety and health problem, how to remove the water in boiling water Dirty problem is the project that we concentrate on studies.

The public places boiling water such as school, hospital, station, Expressway Service, office supply at present is mostly with public burning Based on hydrophone, lack filter device.Water purifying cup type on the market is various, mostly using activated carbon as filter core.Activated carbon filtering Mechanism is filtered using its superpower adsorption capacity, it can be by ion beneficial to human body, unhelpful in water without selection Whole absorption it is clean, finally obtained will be pure water, and long-term drinking is unhelpful to human body.In addition, the size of active carbon particle There is large effect to adsorption capacity.In general, active carbon particle is smaller, and filter area is bigger.So powdered The activated carbon gross area is maximum, and adsorption effect is best, but powdered activated carbon is easy to leak, and causes secondary pollution, is used Person drinks.And active carbon filter core can not clean, and belong to medical disposable material, once blocking can only replace.

There are also filter cup using non-woven fabrics as filter core, non-woven fabrics is because pass size is uneven, it is difficult to weigh effective Filtering accuracy.The non-single layer filter material of non-woven fabrics, needs to obstruct layer by layer and is filtered, and filter efficiency is low, and resistance is big.In addition, nothing Woven fabric filter core also belongs to medical disposable material, once blocking can only replace, for a long time when not used, because material itself is water-absorbent material, Pole is conducive to bacterial reproduction, is easy mouldy or even smelly, it is also desirable to replace filter core in time.Moreover, these water purifying cups are mostly cold to filter Based on water, boiling water can be seldom filtered.

And existing business type boiling water water purifying cup suffers from cup type and is limited, the cup of each specification can only be equipped with specifically Filter core, and cartridge removal installation is complicated, filter element replacing is frequent.

Therefore, a kind of simple and practical, inexpensive, pure physical filtering how is developed, incrustation scale in boiling water, a huge sum of money can be filtered Belong to the particulate matters such as ion, and the corpse such as worm's ovum in water, parasite, bacterium can be removed, moreover it is possible to retain most beneficial ions in water, together Shi Yineng removes the nuisances such as fine solid particles object, worm's ovum, parasite, bacterium in cold water, and installing and dismounting is simple, and filter core fills Setting can be suitble to the business type boiling water water purifying cup of various different cup type to be the main target of the utility model.
