A kind of water purifier drainage screen
Technical field
The invention belongs to water purifier technical field, relate to a kind of water purifier drainage screen.
Background technology
Existing filter assemblies is usually framework and the fixing formation of drainage screen, and drainage screen is filtering
After sewage, need high back voltage to impact, the dirt on drainage screen is rinsed, and high
Pressure impact can make drainage screen cave near geometric center position, it is therefore necessary to improves.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that one
Plant and can resist back flush pressure, it is to avoid the water purifier drainage screen of drainage screen depression.
The purpose of the present invention can be realized by following technical proposal: a kind of water purifier mistake
Filter screen, including rectangular frame and top cap net, it is characterised in that: framework flexes also wraps
Covering outer, drainage screen both sides, framework side corner location is hinged with by rotating shaft tight fit and props up
Strut, rotating shaft is vertical with drainage screen, and support bar one end is connected with rotating shaft, and the other end is solid
Surely having a bracer, a bracer is against on framework, and four support bars are arranged along framework successively,
And support bar can be rotated around rotating shaft, make a bracer be against near drainage screen geometric center position
Put.
After drainage screen uses a period of time, need, to drainage screen back flush, now to enclose
Rotate support bar around the shaft, make a bracer be against near drainage screen geometric center position, i.e.
Can be coordinated by support bar and a bracer and drainage screen is played a supporting role, it is to avoid drainage screen
Middle part is rinsed depression, and under normal circumstances, support bar is arranged along framework successively, energy
Avoid normal filtration is produced impact.
In above-mentioned a kind of water purifier drainage screen, described drainage screen is in geometry
Heart position is provided with caulking groove one, and can rotate support bar, makes a bracer be against in caulking groove one.
In above-mentioned a kind of water purifier drainage screen, described framework is provided with caulking groove two,
And a bracer can be against in caulking groove two.
Therefore after regulation, structure is more stable.
In above-mentioned a kind of water purifier drainage screen, a described bracer is block rubber.
Compared with prior art, present invention have the advantage that
After drainage screen uses a period of time, need, to drainage screen back flush, now to enclose
Rotate support bar around the shaft, make a bracer be against near drainage screen geometric center position, i.e.
Can be coordinated by support bar and a bracer and drainage screen is played a supporting role, it is to avoid drainage screen
Middle part is rinsed depression, and under normal circumstances, support bar is arranged along framework successively, energy
Avoid normal filtration is produced impact.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is that this drainage screen two kinds uses state diagram respectively.
In figure,
1, framework;11, caulking groove two;
2, drainage screen;21, caulking groove one;
3, support bar;31, rotating shaft;32, bracer is propped up.
Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, the technical side to the present invention
Case is further described, but the present invention is not limited to these embodiments.
As depicted in figs. 1 and 2, one water purifier drainage screen of the present invention, including rectangle
Framework 1 and top cap net 2, framework 1 bends and is coated with outer, drainage screen 2 both sides,
Framework 1 side corner location is hinged with support bar 3, rotating shaft 31 by rotating shaft 31 tight fit
Vertical with drainage screen 2, and support bar 3 one end is connected with rotating shaft 31, the other end is fixed with
Propping up bracer 32, a bracer 32 is against on framework 1, and four support bars 3 are successively along frame
Frame 1 is arranged, and can rotate support bar 3 around rotating shaft 31, makes a bracer 32 be against and leans on
Nearly drainage screen 2 geometric center position.
Further, drainage screen 2 is provided with caulking groove 1, and energy near geometric center position
Rotate support bar 3, make a bracer 32 be against in caulking groove 1.Framework 1 is provided with embedding
Groove 2 11, and bracer 32 can be against in caulking groove 2 11.Propping up bracer 32 is block rubber.
After drainage screen 2 uses a period of time, need drainage screen 2 back flush, this
Time rotate support bar 3 around rotating shaft 31, make bracer 32 be against near drainage screen more than 2
What center, can be coordinated by support bar 3 and a bracer 32 and play drainage screen 2
Supporting role, it is to avoid be rinsed depression in the middle part of drainage screen 2, and under normal circumstances, prop up
Strut 3 is arranged along framework 1 successively, is avoided that and normal filtration is produced impact.
Specific embodiment described herein is only to present invention spirit theory for example
Bright.Those skilled in the art can be to described specific embodiment
Make various amendment or supplement or use similar mode to substitute, but without departing from
The spirit of the present invention or surmount scope defined in appended claims.
Although the most more employing framework 1, caulking groove 2 11, drainage screen 2, caulking groove
One 21, the term such as support bar 3, rotating shaft 31, bracer 32, but be not precluded from using
The probability of other term.Use these terms to be only used to more easily and describe reconciliation
Release the essence of the present invention;Being construed as any additional restriction is all and this
Bright spirit is contrary.
