Specific embodiment
The specific embodiment of the application is described with reference to the accompanying drawing.
One embodiment of the application provides water impurity filter, as shown in Figure 1, including shell 1, the mistake in shell 1
Strainer 2, the inlet end positioned at shell 1 and recoil mechanism 3 for carrying out recoil blowdown to the filter screen 2, and are used for
The driving mechanism 5 that driving filter screen 2 rotates in shell 1.
Wherein, the side of the shell 1 offers sewage draining exit 13, is connected at the sewage draining exit 13 for control of sewage disposal mouth
First valve body 14 of 13 opening and closings；The water outlet end of the shell 1 is fixedly installed the second valve for controlling water outlet end opening and closing
Body 15；The filter screen 2 is tubular structure, and one end of filter screen 2 is connect with the water outlet end of shell 1, filter screen 2 and shell
1 is concentric.
In conjunction with Fig. 2, it is described recoil mechanism 3 include with filter screen 2 towards inlet end one end rotation connection and side with
First baffle 31 that shell 1 is fixedly connected, positioned at first baffle 31 away from 2 side of filter screen and be rotatablely connected with shell 1 the
Two baffles 32, and the slide block 34 for driving second baffle 32 to rotate relative to first baffle 31.
The shape of the first baffle 31 and second baffle 32 is round pie, and first baffle 31 and second baffle 32
Size is adapted to the inner cavity of shell 1；
The end face of the first baffle 31 and second baffle 32 offers blowdown port 331 and draining port 332；It is hanging down
Directly in the perspective plane in the axle center of filter screen 2, the blowdown port 331 of the first baffle 31 and second baffle 32 is located at filter screen
The draining port 332 of 2 inside, the first baffle 31 and second baffle 32 is located at the outside of filter screen 2.
In the case where filter works normally, first valve body 14 is closed, and the second valve body 15 is opened, and passes through slide block
34 rotation second baffles 32, are connected to the draining port 332 of the first baffle 31 with the draining port 332 of second baffle 32,
Non-overlapping interlaced of the blowdown port 331 of the blowdown port 331 of the first baffle 31 and the second baffle 32；Water flow
Successively flowed out by the water outlet end of first baffle 31 and the draining port 332, filter screen 2 and shell 1 of second baffle 32
Filter, and the impurity in water flow is filtered by filter screen 2 in the cavity between filter screen 2 and shell 1；
In the case where the mechanism 3 that recoils works, first valve body 14 is opened, and the second valve body 15 is closed, and passes through slide block
34 rotation second baffles 32, are connected to the blowdown port 331 of the first baffle 31 with the blowdown port 331 of second baffle 32,
The draining port 332 of the first baffle 31 and the second baffle 32 drain non-overlapping interlaced of port 332；To mistake
The water inlet of filter is passed through clean water stream, and clean water stream passes through first baffle 31 and second baffle by blowdown port 331
32 blowdown port 331 enters in filter screen 2；During water flow is discharged by filter screen 2 from sewage draining exit 13, the filtering
The impurity in 2 outside of net is flushed to sewage draining exit 13 and is detached from filter.
In this way without adding reflux line, the recoil to filter screen 2 can be realized, improve the speed of recoil；In addition, returning
Stream mechanism be located at filter screen 2 towards shell 1 water outlet end outside, clean water stream can be made to carry out full side to filter screen 2
The flushing of position, prevents impurity from remaining on filter screen 2, reduces the filter effect of filter screen 2.
Optionally, the side wall of the inlet end of the shell 1 offers the sliding slot 11 of arc；The cross section of the sliding slot 11
For T-type, and the big one end of 11 width of sliding slot, towards the outside of shell 1, the cavity of the small one end of 11 width of sliding slot and shell 1 connects
It is logical.The slide block 34 passes through sliding slot 11 and connect with the edge of second baffle 32.
Optionally, the position of the EDGE CONTACT of the inner wall and second baffle 32 of the shell 1 offers the card slot 12 of annular.
The card slot 12 one end small through 11 width of sliding slot, and the depth of card slot 12 is less than the depth of the small one end of 11 width of sliding slot,
The width of card slot 12 is greater than the width of the small one end of 11 width of sliding slot.
The edge of second baffle 32 is fixedly installed the sealing ring 321 being adapted to card slot 12, and the sealing ring 321
Lateral wall is fixedly connected with one end that slide block 34 is inserted into shell 1.The thickness of the sealing ring 321 and the second baffle 32
Thickness is equal.The first baffle 31 is bonded close to card slot 12 close to the side of filter screen 2, and with second baffle 32.It is so close
Seal 321 can either prevent the water flow in shell 1 from flowing out shell 1 by sliding slot 11, and can be avoided sealing ring 321 and hinder first
The fitting of baffle 31 and second baffle 32.
In conjunction with Fig. 3, optionally, be provided in the sliding slot 11 for prevent slide block 34 under non-artificial operation voluntarily

Spring 41, through 34 upper and lower end face of slide block and the positioning through hole 42 that is adapted to the jumping bean of jumping bean spring 41, and for making jumping bean
The jumping bean of spring 41 is detached from positioning through hole 42 in order to stir the press component 43 of slide block 34.The wherein jumping bean spring 41
Jumping bean passes through shell 1 and protrudes into the bottom of the big one end of 11 width of sliding slot.
Optionally, the press component 43 includes being fixed at annular baffle of the positioning through hole 42 far from 1 one end of shell
431 and insertion positioning through hole 42 in and the compression bar 432 with ring baffle sliding connection, and be fixed at 432 court of compression bar
To the locating plate 433 of one end of shell 1.
It is mobile first to dial during the draining port 332 for adjusting first baffle 31 and second baffle 32 is interconnected
Motion block 34 makes slide block 34 drive second baffle 32 to rotate relative to first baffle 31 by sealing ring 321, so that first gear
The draining port 332 of plate 31 and second baffle 32 is interconnected, and the jumping bean of one of jumping bean spring 41 is because of own resilient at this time
Effect be caught in positioning through hole 42, and push compression bar 432 mobile to the direction far from shell 1, so that slide block 34 is clamped
In sliding slot 11, it effectively prevent voluntarily 11 movement along the chute under non-artificial operation of slide block 34.And annular baffle 431 and fixed
The cooperation of bit slice 433 can prevent compression bar 432 complete when jumping bean spring 41 pushes compression bar 432 mobile to the direction far from shell 1
Total detachment positioning through hole 42.
When needing to rotate second baffle 32 again, when being connected to first baffle 31 with the blowdown port 331 of second baffle 32,
Compression bar 432 is pressed down on, the jumping bean for making compression bar 432 that locating plate 433 be driven to press jumping bean spring 41 is detached from positioning through hole 42.Work as jump
When the jumping bean of beans spring 41 is detached from positioning through hole 42, i.e., removable slide block 34, when slide block 34 drive second baffle 32 to rotate,
And then be connected to first baffle 31 with the blowdown port 331 of second baffle 32, the jumping bean of another jumping bean spring 41 is caught at this time
In positioning through hole 42, voluntarily 11 movement along the chute under non-artificial operation of slide block 34 is prevented.So operation can be to stirring
Block 34 is positioned at two different operating positions.
Optionally, the press component 43 further includes between locating plate 433 and annular baffle 431 and being socketed in compression bar
The reset spring 434 in 432 outsides.Reset spring 434, can be in slide block under the cooperation of locating plate 433 and annular baffle 431
34 by the state of 41 clamping of jumping bean spring, so that compression bar 432 is in the state pushed.It just can so differentiate slide block 34
Whether by 41 clamping of jumping bean spring.
