Abstract

The utility model relates to a water purifier, specifically a water purifier with a hyperfiltration membrane filter element, including an outer tube, an upper end closure and a lower end closures set up at the two sides of the outer tube; a purified water outlet and a raw water inlet are respectively set up on the upper and the lower end closures; a hyperfiltration membrane is set up in the outer tube, and an inner tube communicated with the purified water outlet is also arranged in the outer tube; the inner tube is closed by the lower end closure; a pinhole is set up on the wall of the inner tube; the hyperfiltration membrane locates between the inner tube and the outer tube. Thanks to the new type device purifies the current by means of the hyperfiltration membrane filter element, therefore the suspended solids and the macromolecules organic compounds and bacteria in the water body can be eliminated effectively; in addition, a sphere structure design of the upper and the lower end closures are benefit to amortize the pressure brought about by water, so the service life and the security of the water purifier can be improved; at the same time, owing to a blow-off line is set up at the side of the upper end closure, therefore the filtered feculences in the bosom of the hyperfiltration membrane can be rinsed by water through opening an infall of the blow-off line; at last, the maintenance is convenient and the service life of the hyperfiltration membrane can be increased effectively.

Description

A kind of water purifier

Technical field

The utility model relates to a kind of water purifier, specifically a kind of water purifier that has the milipore filter filter core.

Background technology

Raising along with people's living standard, people require more and more higher to quality of life, small-sized water purifier has progressed into common people family, general water purifier inside has included filtration, common filtration is a milipore filter, and milipore filter can effectively be removed the foreign matters such as suspension, larger molecular organics and bacterium in the water body.Existing water purifier structure with milipore filter structure is generally complicated, is not easy to clean and maintenance, the cost height, usage safety performance is not high simultaneously, cause easily blowdown bad, seep water, leak, even water purifier explosion phenomenon.

The utility model content

The technical problems to be solved in the utility model provides a kind ofly can remove suspension in the water body, larger molecular organics and bacterium, have the in-depth filtration structure, and installation, water purifier easy to maintenance.

According to above-mentioned specification requirement, the utility model is realized by the following technical solutions:

A kind of water purifier, the upper and lower end cap that comprises outer tube and be installed on the outer tube two ends, upper and lower end covers and has pure water inlet and former water inlet, milipore filter is installed in the outer tube, the one interior pipe that is communicated with pure water inlet also is installed in outer tube, interior pipe has aperture by the sealing of bottom end cover end on inner tubal wall, milipore filter is between interior pipe and outer tube.

Milipore filter be coated with near two ends places prevent current directly enter by aperture in epoxy resin in the pipe, milipore filter is completely fixed in outer tube by epoxy resin, outer tube as the supporting construction of milipore filter the time also as bearing shell.Current enter the milipore filter from former water inlet, and the water purification that sees through milipore filter enters interior pipe by the aperture on the interior pipe, flows out by pure water inlet again.In order to reduce the influence of hydraulic pressure to end cap, the upper and lower end interior surface is a spherical arc, for the ease of cleaning, also has sewage draining exit on upper end cover.

For the ease of connecting external pipe, on pure water inlet, former water inlet and sewage draining exit, snap joint is installed.

As the improvement to such scheme, above-mentioned interior pipe and outer tube are positioned on the same axle center; Between upper and lower end cap and the outer tube by adhesive firmly, be tightly connected.

The utility model carries out filtration, purification by the filter core of band milipore filter to current, can effectively remove suspension in the water body, larger molecular organics and bacterium etc.; Upper and lower end cap spherical structure design helps the pressure of buffered water to end cap, thereby increase machine service life and safety in utilization, simultaneously be provided with blow-off line in the upper end cover side, open blow-off line and can wash the dirt that milipore filter inside is filtered by the water inlet water, easy to maintenance, can effectively increase service life of milipore filter.

Description of drawings

Accompanying drawing 1 is the utility model example structure schematic diagram; Accompanying drawing 2 is the utility model surface structure schematic diagram.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:

As shown in Figure 1, present embodiment adopts following scheme to realize:

Present embodiment comprises an outer tube 1, and outer tube 1 upper/lower terminal all is equipped with upper end cover 3 and bottom end cover 2, and milipore filter 5 and interior pipe 4 are installed in outer tube 1, near the two end cap place rosette 7 is installed also at outer tube 1.

Bottom end cover 2 inner surfaces are spherical arc, available buffer water is to the pressure of end cap, and bottom end cover 2 bottoms have former water inlet 21, on former water inlet 21 snap joint is installed also, so that the connection external pipe passes through adhesive, sealing between upper and lower end cap and the outer tube 1.Upper end cover 3 inner surfaces also are spherical arc, have pure water inlet 31 and sewage draining exit 32 on upper end cover 3, on pure water inlet 31 and the sewage draining exit 32 snap joint are installed all.In pipe 4 install with outer tube 1 concentric, lower end closed, the upper end is communicated with pure water inlet 31, on tube wall and have a plurality of apertures 41.Milipore filter 5 is between interior pipe 4 and outer tube 1, axially install, be filled with epoxy resin 6 at milipore filter 5 near in the gap at two ends, by epoxy resin 6 milipore filter 5 is fixed in the outer tube 1, certainly, epoxy resin 6 can not get lodged in the port of milipore filter 5, and epoxy resin 6 can prevent that current from directly directly not entering into interior pipe 4 by aperture 41 by milipore filter 5.

During operate as normal, at first sewage draining exit 32 is blocked, without the former water that purifies from bottom end cover 2

Former water inlet 21 enters milipore filter 5 inside, and former water sees through milipore filter 5 filtration, purifications and obtains water purification under the pressure of former water, because sewage draining exit 32 is blocked, water purification is pipe 4 inside in small holes 41 enters into again, flow out by pure water inlet 31 at last.

When needs clean water purifier, at first block pure water inlet 31, open sewage draining exit 32, current enter milipore filter 5 inside from former water inlet 21, because pure water inlet 31 is blocked, current can only flow out from sewage draining exit 32, simultaneously the dirt of milipore filter 5 inside is discharged, thereby finish the cleaning of water purifier.
