Description

The no need to replace element water purifier

The utility model relates to a kind of water treatment device, particularly a kind of no need to replace element water purifier, and it is applicable to the deep purifying of tap water, is not only applicable to general occasions such as office, is particularly useful for family.

Its structure of similar household water filter of the prior art as shown in Figure 1, it mainly by water tap connector 1 ', bodice 2 ', switching piston 4 ', switch handle 6 ', filter bowl 9 ' and filter core 8 ' form, wherein filter bowl 9 ' be enclosed within filter core 8 ' outside and bodice 2 ' thread connection, filter core 9 ' be inserted in bodice 2 ' centre hole 5 ' on, it is shaped as column, filter core 9 ' generally adopt physisorphtion, medium is mainly gac; Water tap connector 1 ' be adhered to bodice 2 ' on; Switch handle 6 ' be connected to switching piston 4 ' on, switching piston 4 ' can bodice 2 ' the chamber in back and forth movable; Switch handle set 7 ' location switching handle 6 ', and with bodice 2 ' screw attachment; The switching piston 4 of this water purifier ' changeable water purification and Yuan Shui.When switching water purification as shown in Figure 2, to switch handle 6 ' pull to the water purification side, former water through water tap connector 1 ' enter bodice 2 ', and through bodice 2 ' side opening 3 ' enter filter bowl 9 ' in, from filter core 8 ' the top flow into, after filtering purify waste water from filter core 8 ' bottom through bodice 2 ' centre hole 5 ' flow out from water outlet A at last; When switching former water, as shown in Figure 3, switch handle 6 ' pull only to former water side, former water just through water tap connector 1 ' enter bodice 2 ', and flow out from water outlet A; Because its filter core of this household water filter adopts physisorphtion, medium is mainly gac, during work with organic or inorganic large granular impurity and water sepn, so after using the certain period, dirt blocks circulation easily, filter core can lose purification efficiency, so filter core must regularly replace,, can cause water purifier water quality to worsen if filter core exceeds the time limit to use, be equivalent to water quality and polluted once more, be unfavorable for that people's is healthy.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of no need to replace element water purifier that can reach purifying of drinking water, the filter core life-time service is not changed is provided.

The purpose that the utility model proposed can be achieved through the following technical solutions: this water purifier comprises water tap connector, bodice, filter bowl, filter core, piston and handle, the water tap connector links to each other with bodice, filter bowl is enclosed within the filter core outside and connects with bodice, its constructional feature is: have sewage outlet, former water out and pure water inlet greatly on one's body, filter core be shaped as tubular, regenerator is installed at the top of filter bowl injects lid, it connects with filter bowl.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 4, the utility model mainly is made up of water tap connector 1, bodice 2, piston 10, handle 11, filter core 8 and filter bowl 9, water tap connector 1 links to each other with bodice 2, water tap connector 1 in the present embodiment is socketed on the bodice 2, like this, water purifier energy left-right rotation simultaneously, also has sewage outlet B, former water out C and pure water inlet D on bodice 2; Piston 10 is movable parts of realizing water purification, back flushing, former water and refresh function, and this piston 10 be a rotating-type piston, and it is plugged in the centre hole of bodice 2 and by piston stop ring 12 and locatees, but piston stop ring 12 is connected with bodice 2 screws; Handle 11 links to each other with an end of piston 10, and the handle 11 in the present embodiment is plugged on an end of piston 10, disposes water purification, back flushing, former water on the handle 11 and regenerate four to switch shelves; Filter core 8 is plugged on the mesopore 14 of bodice 2, filter core 8 be shaped as tubular; Filter bowl 9 be enclosed within filter core 8 outside and with bodice 2 thread connection; Regenerator injects and to cover 15 tops that are positioned at filter bowl 9, can be threaded with filter bowl 9.

Filter core 8 in the utility model adopts the physical filtering method, spray molten silk spinning filter core with special polypropylene, it contains the micropore of the stepped distribution of abundant 0.4-5 μ (thousandth millimeter), have height and receive the characteristic that dirt, high detergency and dirt easily free, under the regenerator effect, can repair sth. old and make it as good as new, reach the purpose of no need to replace element; And regenerator is a natural phant acids extract, nontoxicity; Filter bowl 9 transparent material manufacturing is when filter core 8 can be regenerated during by white yellowing.

Referring to Fig. 5, Fig. 6, Figure 10, handle 11 is pulled to the water purification position, during use (when the needs water purification), former water imports piston 10 centers through water tap connector 1, mesopore 14 conductings of hole 10-3 in the piston 10 and bodice 2, former water outwards infiltrates in the filter bowl 9 through filter core 8 centers, flows out from pure water inlet D through lateral opening 13 of bodice 2 again.

Referring to Fig. 5, Fig. 7, Figure 11, when the needs back flushing, handle 11 is pulled to the lateral opening 10-4 of piston of back flushing position piston 10 this moment and lateral opening 13 conductings of bodice 2, and the back plug 10-2 of piston 10 blocks former water out C, former water is oppositely gone out from centre hole through filter core 8, and sewage is then discharged from sewage outlet B.

Referring to Fig. 5, Fig. 8, Figure 12, when the former water of needs, handle 11 pulled to former water level put, piston hole 10-3 in the piston 10 and former water out C conducting, former water directly flows out from former water out C.

Referring to Fig. 5, Fig. 9, Figure 13, when needs use regenerator, handle 11 to be pulled to reproduction position, the mesopore 14 of bodice 2, lateral opening 13 is all sealed by preceding plug 10-1 in the piston 10 and back plug 10-2, can carry out filter core 8 regeneration this moment; Turn on regenerator and inject and cover 15, inject regenerator, then regenerator is injected and cover 15 and cover again and tighten, keep 12 hours after, washed five minutes at the back flushing shelves, from sewage outlet B discharge, filter core 8 promptly obtains regeneration with sewage.

The utility model compared with prior art has the following advantages: 1, structural design is closed Reason, easy to use, function is many; 2, filter core can use for a long time, need not change, simultaneously again Can make drink water purifying; 3, need not change owing to filter core, so the operating cost of whole product Reduce.
