Toward being arranged in filter interior, installing and dismounting is cumbersome, and cleaning is inconvenient, it is long using the time and can only will be entire after plugged filter
Filter replacement.
Summary of the invention
It is an object of the invention in view of the above-mentioned drawbacks in the prior art, provide a kind of backwashed filtration cock, side
Just tap net-filter assembly is washed away.
For achieving the above object, present invention employs following technical solutions: a kind of backwashed filtration cock, including
Faucet body and the filter device being connected with the faucet body, the filter device are equipped with water inlet, the filtering dress
It sets including net-filter assembly and inner wall, the filter device is divided into the first circulation passage and the second circulation passage, institute by the inner wall
Inner wall is stated equipped with the second recirculation hole, the net-filter assembly is located in second circulation passage, and first circulation passage is equipped with
Shut-off valve opens the shut-off valve, enters water flow through the second recirculation hole from water inlet when needing to backwash net-filter assembly
Second circulation passage backwashes the net-filter assembly.
In addition, the present invention also proposes following attached technical scheme: the net-filter assembly and second circulation passage activity
Connection.
The filter device further includes piston, piston setting in the second circulation passage side wall, the piston with
Side wall contact position is equipped with the first gasket.
The net-filter assembly includes connecting rod, cylinder bar and filter screen, and the cylinder bar is connected with the connecting rod.
The filter screen is arranged in the connecting rod.
The inner wall offers the first recirculation hole, the cylinder bar and the second circulation passage screw-type connection, the cylinder
Bar is to be opened and closed the first-class through-hole.
The shut-off valve is between the first recirculation hole and the second recirculation hole.
Compared with the prior art, the present invention has the advantages that
1. tap uses after a certain period of time, by opening shut-off valve and adjusting cylinder bar position, water flow recoil filter wash is realized
Net；
2. the water flow after rinsing can flow out from piston, easy to use, can clear up at any time impurity in filter device with
Bacterium；
3. cylinder bar and the second circulation passage screw-type connection, are convenient for changing strainer.
Detailed description of the invention
Fig. 1 is normal water-using structure schematic diagram of the invention.
Structural schematic diagram when Fig. 2 is present invention backwash.
Specific embodiment
In conjunction with the preferred embodiment and its attached drawing is further non-limitingly described in detail technical solution of the present invention.
As shown in Figure 1 and Figure 2, a kind of backwashed filtration cock, including faucet body 1 and filter device 2, filtering dress
It sets 2 and is equipped with water inlet 21 and water outlet 22, water outlet 22 is connect with faucet body 1, and water inlet 21 and water pipe (not shown) connect
It connects.
Filter device 2 is hollow pipeline structure, and inner wall 3 is equipped with inside filter device 2, and inner wall 3 is equipped with flange 31, inner wall 3
Hollow pipeline is divided into the first circulation passage 4 and the second circulation passage 5, inner wall 3 offers the first recirculation hole 31 and the second circulation
Hole 32,4 side wall of the first circulation passage are equipped with shut-off valve 6, and shut-off valve 6 is between the first recirculation hole 31 and the second recirculation hole 32.
It is equipped with net-filter assembly 7 and piston 8 in second circulation passage 5, net-filter assembly 7 is flexibly connected with the second circulation passage 5.Net-filter assembly
7 include connecting rod 71, cylinder bar 72, handle 73 and filter screen 74, and 72 both ends of cylinder bar are separately connected bar 71 and are fixedly connected with handle 73,
Filter screen 74 is set in connecting rod 71, and cylinder bar 72 is preferably external thread type cylinder bar, and 5 side wall of the second circulation passage and inner wall 3 are equal
Equipped with the screw thread 75 matched with cylinder bar 72, cylinder bar 72 can ensure that water flow will not flow out the second circulation passage 5, when needing replacing
When filter screen 74, rotational handle 73 is only needed by 72 whiz of cylinder bar and extracts the second circulation passage 5 out.The setting of piston 8 is in the second circulation
On 5 side wall of channel, and it is located at the right side of filter screen 74, piston 8 and side wall contact position are equipped with the first gasket 81, it is ensured that piston 8
Leakproofness, make water flow that can not flow to the external world from piston 8.
When normal use, shut-off valve 6 is closed, water flow flows into the second circulation passage through the first recirculation hole 31 from water inlet 21
5, water flows through and flows into faucet body 1 by the second recirculation hole 32 after filter screen 74 filters.When needing to clean filter screen 74, open
