Description
Technical field
The utility model is related to cup field, more particularly to a kind of cup for carrying out automatic fitration to water by strength.
Background technology
Cup generally comprises cup body and cover two parts or only a cup body part, is easy to carry, is that people drink water
Apparatus.This cup does not possess the function of filtration, purification typically, is not united for environmental pollution increasingly serious today, water quality
One, river can not reach the standard drunk, and in particular cases no running water such as earthquake at one's side, rain mighty torrent, people are gone out trip
Row, field survivorship, mine workman occur mine disaster, drink sewage not up to standard using this cup, it is impossible to meet in particular cases
Use.The healthy of people can greatly be injured by with life.
In order to avoid the defect that above-mentioned cup is brought, people have invented a kind of installation detachable filter device in the middle part of cup body
Cup, as described in the Chinese utility model patent of Patent No. 201020286163.8.There are several defects in this cup：
1) it is filtering step by step by water, realizes filtration, purification, filtration time is long；
2) running water can only be poured into be not suitable for occurring to use under disaster scenario；
3) need to outward winding down when drinking water to screw cup lower cover, in-convenience in use；
4) due to being frequently necessary to outward winding cup, so easily causing the pollution of filter, secondary pollution is formed；
5) complicated, cost is high.
Utility model content
The purpose of this utility model is to provide a kind of strength filtering cup, and it can overcome the drawbacks described above of prior art,
Realize depth-type filtration.
According to one side of the present utility model there is provided a kind of strength filtering cup, including shell and inner bag, shell is set
There are the first oral area and the first cavity, inner bag can be put into shell along the first oral area,
The outer wall of inner bag and the inwall of shell can be fitted close,
The inside of inner bag is provided with the second cavity, and the bottom of inner bag is provided with detachable filtering layer, and one end of filter layer is by interior
Lead to the first cavity for the bottom of courage, and the other end of filter layer leads to the second cavity.
The beneficial effects of the utility model are when in use, water first to be filled in shell, then inner bag is put along the first oral area
Enter in shell, because shell and inner bag are close-fitting, the water in the first cavity can pass through inner bag bottom under inner liner pressure
Filter layer enter the second cavity in, so as to obtain filtered drinkable clean water in inner bag；Filter layer can be dismantled,
When filter effect is deteriorated, the filter core of filter layer can be changed.Strength filtering cup of the present utility model, filter layer is dispatching from the factory
When pack, be not used filtering function when do not dismantle this layer packaging, it is to avoid pollution；When filter water is needed, tear open
Fall wrapper, you can realize the filtering function of cup；Filtration time, which is shortened to, may filter that out within tens seconds and reaches standard for drinking
Water, convenient and swift, filter layer is not required to unpick and wash within one month, and satisfaction is in particular cases used, and particularly can meet frequent exist
The outer consumer for going on business or carrying out outwork for a long time.Because the replacing of filter core is regarded by the suspended contamination quantity of filter water
Depending on, for running water or the river and well water of preferable water quality, the use of filter core during daily using filtering function for single drinking-water
Phase may be up to 4 months, with very strong practicality and portability.
In some embodiments, in addition to dividing plate, dividing plate is located between filter layer and the second cavity, and dividing plate is provided with the
One one-way pressure valve, the first one-way pressure valve is depressed outside to be opened to the second cavity.Due to the first unidirectional pressure on dividing plate
Power valve is only opened to the second cavity, after water enters the second cavity through filtering, reversely will not flow to the first cavity by the second cavity
In.Thus, the filter efficiency and filtration yield of water are improved.
Also include the second one-way pressure valve on shell, the second one-way pressure valve is located at inner bag and the lower section at body seal,
Second one-way pressure valve is depressed outside can close shell, and when forming negative pressure in the first cavity, the second one-way pressure valve energy
Enough to shell inner open, the first cavity is set to be communicated with ambient atmosphere.Thus, when being filtered to water, inner bag is put into outer
In shell, the water in the first cavity produces very big hydraulic pressure, closes the second one-way pressure valve and opens the progress of the first one-way pressure valve
Filtering, the water after filtering enters in the second cavity, and when needing to take out inner bag from shell, negative pressure is formed in the first cavity,
External atmosphere pressure can press to the second one-way pressure valve opening, and the first cavity is communicated with ambient atmosphere, balance inner and outer air pressure,
So as to which inner bag smoothly be taken out.
In some embodiments, the outer wall of inner bag is additionally provided with hand grip portion, and hand grip portion is located at the top of inner bag, hand grip portion table
Face can do anti-skidding setting.Thus, when inner bag is put into shell, can hold with a firm grip shell on the other hand, the hand grip portion for inner bag of holding with a firm grip on the other hand
Installed, not only facilitated, moreover it is possible to prevent hand from inner bag is made dirty further polluted-water.
In some embodiments, in addition to cup lid, inner bag is provided with the second oral area, and cup lid is engaged with the second oral area.This
Place, cup lid can be to be threadedly coupled with the connected mode of the second oral area, or cover-turning hinge formula, push type or market are taken up an official post
A kind of connected mode.When install filtering water body to inner bag and shell, cup lid is opened, makes the second cavity and ambient atmosphere phase
It is logical, be easy to filtering, it is to be filtered after the completion of cover cup lid.Thus, prevent the water after filtering when not drinking in time during storage
It is secondary polluted.
In some embodiments, the outer wall of inner bag is provided with external screw thread, and the inwall of shell is accordingly provided with internal thread, inner bag
Can be in the cooperation precession shell by external screw thread and internal thread.Thus, will by screw thread when carrying out assembling filter to cup
It is convenient and strength-saving in inner bag precession shell, and be fitted close by internal thread with externally threaded, prevent water to be filtered from first
Overflow in portion.
In some embodiments, inner bag is all covered with external screw thread, the inwall of shell only the first oral area from bottom to top
Provided with internal thread.Thereby it is ensured that while inner bag can smoothly load shell and good seal completely, reducing adding for shell
Work process.
In some embodiments, the outer wall of inner bag is provided with elastic ring, and the inwall of elastic ring and shell can be fitted close.
Thus, during installation, inner bag is pressed into shell by strength, elastic ring is fitted closely with outer casing inner wall, prevents leak, due to bullet
Property circle is flexible, is not strongly to make consumer very laborious herein, but what ordinary consumer was easily able to.
