Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification sheets word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
As Figure 1-3 be according to a kind of way of realization of the present utility model, comprising:
Housing 1, becomes cylindric, is provided with accommodating cavity, the open upper end of described housing 1 in it; End cap 2, it seals the upper end being arranged on described housing 1 in a detachable fashion, and when normally working, end cap 2 encloses the open ports of housing 1 upper end; Ultra-filtration element, it is longitudinally arranged on described accommodating cavity inside in a suspended manner, and the water outlet of described ultra-filtration element is connected to described end cap 2 lower surface in a detachable fashion; Wherein, longitudinally throughly on described end cap 2 offer venting hole 33, described venting hole 33 is upwards extended with a cylindrical boss 3 along described end cap 2 upper surface, described protuberance 3 center offers the pin hole 31 straight-through with described venting hole 33, for limiter exhaust footpath, avoid due to misoperation, water too much in exhaust process is flowed out in accommodating cavity.Extraneous water enters in described accommodating cavity from one end of ultra-fine filter end cap 2, and due to the effect of hydraulic pressure, extraneous water flows out from its water outlet through the filtration of ultra-filtration element, and the water outlet of ultra-filtration element is communicated with the water outlet of described end cap 2, thus completes filtration procedure.Once have air accumulation in the accommodating cavity of described ultra-fine filter, air can be gathered in the upper end of accommodating cavity, the lower end of end cap 2, if discharged not in time, the air assembled can get more and more, the water level in accommodating cavity is caused to be limited in a lower position by air pressure, water in accommodating cavity can only by having the place of contact area to flow out ultra-fine filter with ultra-filtration element, the ultra-filtration element position of that is playing filter effect is limited, cause water outlet not smooth, do not reach filter effect, affect water quality, the top of ultra-filtration element cannot play a role in filtering simultaneously, the bottom of ultra-filtration element subjects whole filtration work, cause decline the work-ing life of ultra-filtration element, need often to change ultra-filtration element, huge inconvenience is brought to user while increasing cost, the utility model is provided with venting hole 33 on upper end cover 2, the upper surface of end cap 2 is provided with protuberance 3, protuberance 3 offers the pin hole 31 be communicated with venting hole 33, can by controlling opening of vacuum 31, close to discharge the air in accommodating cavity, solve the problem and drawback.Preferably protuberance 3 can be connected with pipeline, official road be provided with valve, such as magnetic valve, manual valve etc.Valve open, due to the pressure in accommodating cavity, air is rapidly by outside venting hole discharge machine, and can not affect the normal water outlet of water-purifying machine, until from venting hole during water outlet, air drains, closure valve, opens when exhaust next time.The ultra-fine filter that this kind can be vented effectively eliminates the air in ultra-fine filter, without the need to increasing other devices, easy to operate, make the contact surface of filtered water and ultrafiltration core keep maximizing, enhance filter effect, water quality is better, current are more unobstructed, extend the work-ing life of ultrafiltration core simultaneously.
In technique scheme, the open ports of described housing 1 upper end is extended downwards internal thread part, described end cap 2 periphery is extended downwards the external thread part 23 mated with described internal thread part, and end cap 2 is threaded with housing 1, can seal and can be easy to open.The lug boss consistent with described external thread part 23 lower rim shape is provided with in described internal thread part bottom, described lug boss is provided with sealing-ring, described external thread part 23 lower rim is supported on described sealing-ring, thus ensure that housing 1 is airtight with the connection of end cap 2.
As shown in Figure 3-4, in technique scheme, the lower surface central position of described end cap 2 is extended downwards annular cavity portion 24, and the water outlet clamping of described ultra-filtration element is arranged in described annular cavity portion 24, and is tightly connected with it.Transversely throughly on described end cap 2 offer water outlet 22, described water outlet 22 is connected with the water outlet of described ultra-filtration element is through by described annular cavity portion 24, as shown in Figure 4.Transversely throughly on described end cap 2 offer water-in 21, described water-in 21 is communicated with described accommodating cavity inside.Extraneous water enters in accommodating cavity from water-in 21, and fill full, due to the effect of hydraulic pressure, water in accommodating cavity is filtered by ultra-filtration element, described annular cavity portion 24 is entered from its water outlet, water outlet 22 again by being communicated with annular cavity portion 24 discharges ultra-fine filter, thus completes the filtration procedure of ultra-fine filter.
In technique scheme, the external diameter of described protuberance 3 sets in the mode consistent with described water purifier hydraulic pipe internal diameter, hydraulic pipe can directly be inserted on described protuberance 3, also can be connected with described protuberance 3 by joint, be provided with the protection department 32 being connected location for auxiliary described protuberance 3 with described hydraulic pipe in the periphery of described end cap 2 upper convex portion 3, described hydraulic pipe or joint are fastened on the position between described protuberance 3 and annular shield portion 32.
The ultra-fine filter be vented of the present utility model, the upper end cover of ultra-fine filter offers venting hole, by controlling the open and close process of venting hole, without the need to increasing other devices, effectively the air in ultra-fine filter being discharged water purifier, making the contact surface of filtered water and ultra-filtration element keep maximizing, enhance filter effect, water quality is better, and current are more unobstructed, extends the work-ing life of ultra-filtration element.Meanwhile, control mode is simple, precisely convenient, and can not affect the normal work of water purifier, has practical value widely.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification sheets and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
