Description

Running water filter

The utility model belongs to a kind of tap water filter device, says in detail, is to belong to a kind of family expenses (or small-sized) running water ultrafiltration apparatus.

In the past, general family expenses (or small-sized) running water ultrafiltration apparatus all belonged to a kind of fixing tactic pattern: constitute ultrafiltration module by the filter core and the upper and lower casing that with the hollow fiber ultrafiltration membrane are filter medium, refill a shell and form outside this assembly.Running water enters from the assembly lower house, combines in the assembly upper shell by milipore filter by hydraulic pressure then, chews or the tap outflow from the water outlet that is stuck in shell through the upper shell delivery port again, just obtains ultrafiltration water.This traditional fixed structure pattern, its basic shortcoming is that the continuous impurity that produces gets nowhere when filtering, can't wash naturally at any time, so that frequently disassembly, cleaning of user, not only trouble and fragile filter core shorten its service life.Obviously, this have only ultrafiltration and do not have the tactic pattern of cleaning function, do not constitute a kind of complete system.In addition, unlikely excessive for making shell sizes, ultrafiltration module can not be big, and it is then very limited that it handles the water yield.

The purpose of this utility model just is: change this traditional fixed structure pattern, a kind of new design is provided, overcome the above-mentioned shortcoming of general family expenses (or small-sized) running water ultrafiltration apparatus in the past, it need not frequently be dismantled and cleaning naturally at any time, become a kind of holonomic system of family expenses (or small-sized) ultrafiltration-cleaning-water supply, need not add casing and handle the water yield and increase.

Above-mentioned purpose of the present utility model can reach by following new design:

It comprises: with the hollow fiber ultrafiltration membrane be filter medium filter core, hold the lower house of filter core and hold the upper shell of ultrafiltration water, upper shell is equipped with ultrafiltration water depotition cock, and lower house is equipped with the running water inlet valve and need not dismantles the running water outlet tap that can clean filter core at any time naturally.

Though this new design is simple, but changed traditional fixed structure pattern, do not increased a running water outlet tap with important not being both in the past at lower house, next is to have cancelled original shell, compared with the past, its positive effect or advantage are obvious: 1. owing to adorned the running water outlet tap holding to increase on the lower house of filter core, be fit to very much a large amount of situations of using running water of family's needs, the impurity of holding back during ultrafiltration can clean up at any time naturally, the labor of having exempted the cleaning that in the past must frequently dismantle at one stroke, greatly facilitate the user, and damage the phenomenon of hollow fiber ultrafiltration membrane when avoiding dismantling, increased the service life of filter core.2. adorned the running water outlet tap owing on lower house, increasing, by a tool ultrafiltration in the past and for the ultrafiltration water function become possess ultrafiltration simultaneously, for ultrafiltration water, cleaning, for four kinds of functions of running water, and become a kind of holonomic system of family expenses (or small-sized) ultrafiltration-cleaning-water supply at one stroke.Fundamentally changed the former state that does not in the past become system.3. cancelled shell, made under the suitable situation of appearance and size, filter core is increased.4. 1. aforementioned and synthesis result 3. can make the life-span obviously increase, if need not change ultrafiltration module in 1 year in the past, so now then can be more than 3 years renew cartridge more, handle the water yield and be increased to now more than 15000 liters by in the past 5000 liters, it is saved and is worth is considerable.

Below in conjunction with its most preferred embodiment of description of drawings:

Fig. 1 is a basic structure principle schematic of the present utility model, is suitable for a large amount of occasions of using running water of family's needs, is one of most preferred embodiment.Upper shell 1 all has rubber seal 9 sealings with the contact position of filter core 3 and the contact position of filter core 3 and lower house 2, and upper shell 1, filter core 3 screw by sleeve 10 with lower house 2 and be that one, net 5 are enclosed within on the filter core 3 in order to protection hollow fiber ultrafiltration membrane 4.Just the time spent is closed ultrafiltration water depotition cock 6 earlier, opens running water outlet tap 8, treats can come into operation when leading 8 water outlets are unblocked.When connecing for the first time, suitablely tap 6 is opened sky put and connect usefulness in several minutes more earlier with ultrafiltration water.Can open tap 8 behind the cutout cock 6 at any time and connect and use running water, the impurity of holding back during ultrafiltration then can flow out by tap 8 at any time, make the hollow fiber ultrafiltration membrane 4 of filter core 3 obtain cleaning naturally.

Fig. 2 is the structural principle schematic diagram of another most preferred embodiment, a large amount of occasions of using the occasion of running water but also being fit to be of little use (or need not) running water not only be fit to, be on the basis of above-mentioned most preferred embodiment, installed running water recoil mechanism additional: on the running water water inlet pipe of lower house 2, lead to the water pipe 11 of straight-through upper shell 1, valve 12 is housed on the water pipe 11.In the occasion of running water that is of little use, clean impurity in order not dismantle, then can so operate: behind cutout cock 6 and the valve 7, open valve 12, open tap 8 again, running water enters upper shell 1 by water pipe 11, again from the inside of the doughnut 4 of filter core 3 thoroughly to the outside, thereby the impurity of holding back is recoiled, and discharge from tap 8, after the impurity cleaning finishes, stop recoil with current.Cutout cock 8 and valve 12 are then opened tap 6 and valve 7 again, and at this moment, tap 6 is wanted to connect after the abundant emptying again and use ultrafiltration water, with the cleaning of assurance ultrafiltration water.This recoil is to use tap water hydraulic, is different from the general recoil of carrying out with pump input ultrafiltration water, and any family just can recoil easily without pump, and is simple.

In order to satisfy the situation of needs heat (drink) ultrafiltration water such as making tea, the utility model also recommends such the best to implement: on the scheme basis of Fig. 1 or Fig. 2 representative, the function and the mechanism thereof that keep cooling ultrafiltration water, add the common electrical heating tank device and the corresponding hot ultrafiltration water depotition cock that are exclusively used in the heating of ultrafiltration water again, for this reason, also must draw one section water pipe of band valve and lead to heating tank from the ultrafiltration water outlet pipe of housing 1.Be attractive in appearance and convenient installation, should be assembled in filter and heating tank in the housing.Electrical heating tank can be selected for use from prior art or design, and heating also can be selected for use more advancedly except that resistance wire, as PTC etc., can optionally reach factors such as cost and decides.So implement, all increased heat supply ultrafiltration water function than aforementioned two kinds of enforcements, thereby increased the applicability of product.
