Description

Portable water purification kit

The utility model relates to a kind of water purifier, especially a kind of portable water purification kit of suitable field usage.

Existing water purifier mostly adopts desk-top natural filtration type, utilizes the deadweight of the processed water filtration medium of flowing through to reach the water purification purpose downwards.Such water purifier volume is big, only limits to indoor use, and only is suitable for handling the water source of cleaning such as tap water.Chinese patent 2226485Y discloses a kind of " portable band pump water purifier ", and its constitutional features is to connect manual pump above the three-way body at one, connects strainer tube below, and controls the turnover of water by two ball valves.Though this water purifier structure is simpler, the bodily form is elongated, carries inconvenience, and must be connected with water pipeline, the field usage bad adaptability.In addition, the microporous filter tube effect that this water purifier adopts is single, and purifying water effect is relatively poor.

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of portable water purification kit is provided, and it has easy to carry, uses not to be subjected to condition restriction, the very significant advantage of filter effect.

The utility model is achieved through the following technical solutions its purpose.A kind of portable water purification kit comprises: by cylindrical shell, connect the seat of honour, following of cylindrical shell and be worn over the housing that the drinking-water bowl cover on the cylindrical shell is formed, be positioned at the hand air pump of cylindrical shell central authorities, the filtration unit between housing and the air pump, and discharging device.Described hand air pump comprises: the air pump barrel that is positioned at cylindrical shell central authorities, the piston rod at air pump barrel center, the piston that is connected with piston-rod lower end, intake valve, the handle that is connected with the piston rod upper end, the water filling port lid that is threaded with the air pump barrel upper end, be installed in the vent valve of air pump barrel lower end, pneumatic pump is whole to be connected with the seat of honour by the water filling port lid.Described filtration unit is made up of ceramic fine filter, molecular sieve coarse filter, high-density yarn fabric fore filter, coarse filter is the sintered pipes structure, be installed in the ceramic fine filter pipe, the tubular fore filter is supported on the internal surface of coarse filter with spring piston ring, strainer after the assembling is installed between the upper and lower seat, and described discharging device comprises: the base that is connected with the seat of honour, insert the base lower end aqueduct, be connected the rising pipe on the base.And it is fastening with rectangular seal and base with the nut pad.

Described piston and the intake valve that is connected with piston rod one end, its piston bush is contained on the piston rod, leaves airspace, and intake valve above the piston and gasket are fixed on the piston rod together, slide among a small circle up and down at piston rod for limited piston, piston rod end is inserted with steady brace.

The vent valve that install described air pump barrel lower end, by sealing middle part, termination have aperture vapor pipe, form with the rubber hose that tightly is enclosed within the vapor pipe outside.

Described water filling port lid adopts with the seat of honour and is threaded, and is to be connected with the internal thread in water filling aperture, the seat of honour with water filling port lid outside screw, and fills up rectangular seal between port lid and seat of honour contact plane.

There is link described drinking-water bowl cover outside, and the groove that inserts link is arranged on the seat of honour, is provided with two back of the body rings on the cylindrical shell.

The utlity model has following advantage:

1, compact construction is easy to carry.Because the utility model has been taked: three layers of cylindrical shell structure of shell, strainer, air pump, water glass is held concurrently, and water purifier covers, tender filling hole cover is held concurrently the gas pump casing cover, rotating rising pipe structure, but seat is casing structure design such as Fixed-Filter again up and down, effectively utilized the space, make the compact construction volume little, be easy to carry.

2, three layer filtration, the efficient purification.Because the utility model has adopted following three cover strainers: (1) ceramic fine filter is to 100% high precision strainability of germ tool, the surface is through oozing art breading such as silver, even there is remaining micro-germ also can't be impregnated with the ceramic surface existence of silver ions in addition.The project organization of easy accessibility can make it regularly disintegrate and scrub the surface, so there is not secondary pollution.(2) coarse filter has used the molecular sieve absorbing structure, can efficiently adsorb sterilant, weedicide, the peculiar smell of chemical pollutant such as industrial solvent and various materials.(3) fore filter is made with the high-density yarn fabric, impurity such as main filtering silt.Therefore, processed water can highly filtering noxious bacterium and impurity, obtains the tap water of cleaning, safety, health.

3, simple to operate, easy to use.Because the water intaking mechanism that the utility model has adopted hand air pump promptly presses and promptly gets, and is simple to operate.Compared with the prior art, cancel the connection hose nozzle, changed the formula of pouring into into, more adapted to the field usage condition.Have the drinking-water link, rising pipe is rotatable in addition, uses very convenient.The place that can be widely used in travelling outdoors, field work, field army etc. does not have source of clean water.

The utility model is further described by embodiment below in conjunction with accompanying drawing.
