Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawings
And embodiment, the present invention is further elaborated.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the rain water filtering device of the present invention includes generally elliptical housing, this housing
Including the upper shell 1 being set in together successively, filter element 2 and lower house 3.The top of upper shell 1 sets
It is equipped with the rainwater-collecting interface tube 11 of circle.
As depicted in figs. 1 and 2, filter element 2 be provided centrally with a point water plate 21, in the present embodiment,
Dividing water plate 21 is umbrella, and umbrella cover is towards the direction of rainwater-collecting interface tube 11.Water plate 21 is divided to pass through
The bracing frame 25 integrally formed with point water plate 21 and the open end of refuse collecting mouth 31 are removably
Connecting, the preferably quantity of bracing frame 25 is 3, so can be fixedly supported a point water plate 21.Point
The lower section of water plate 21 is provided with annular filter screen 22, and the outer shroud end face of annular filter screen 22 is interior with filter element 2
Wall connects, and the internal ring end face of annular filter screen 22 is removably connected to the opening of refuse collecting mouth 31
Portion, such connected mode can avoid rainwater filter without annular filter screen 22 just flow directly into clean
Water collecting chamber 32, the wire side of annular filter screen 22 tilts along outer shroud end face gradually downward to internal ring end face.
Point water plate 21 and annular filter screen 22 in the present embodiment are shaped such that through rainwater-collecting interface tube 11
After the rainwater fallen into clashes into point water plate 21, rainwater shunting is just made rain by point water plate 21 of umbrella-shaped structure
Water is along the edge flowing of point water plate 21, and then flows on the annular filter screen 22 below point water plate 21,
Foreign material are promptly separated from rainwater by annular filter screen 22, and water purification just falls in water purification collecting chamber 32.
In the present embodiment, the aperture of annular filter screen is 0.28mm, through the rainwater that annular filter screen 22 filters, no
The foreign material such as the leaves being only capable of removing in rainwater, the water quality of filtered rainwater can reach to meet pouring and
The water quality requirement flushed the toilet.
The bottom of lower house 3 is provided with foreign material outlet 33, and the side of lower house is provided with water purification and discharges
Mouth 34, in the present embodiment, water purification outlet 34 can be with water storage apparatus (not shown) phase
Even.Lower house 3 be provided centrally with refuse collecting mouth 31, refuse collecting mouth 31 and foreign material outlet
33 connections, the foreign material falling into refuse collecting mouth 31 can be discharged through foreign material outlet 33.Refuse collecting
Space between outer wall and the lower house 3 of mouth 31 is formed as water purification collecting chamber 32, through annular filter screen
22 rainwater filtered just flow in water purification collecting chamber 32, and the water purification in water purification collecting chamber 32 can be via
Water purification outlet 34 flows to water storage apparatus；The foreign material intercepted by annular filter screen 22 are just along annular filter screen
The wire side of the inclination of 22 falls into the refuse collecting mouth 31 of lower house 3 and simultaneously via foreign material outlet 33
Mesh is dynamic discharges.
In a preferred embodiment, the sidewall of refuse collecting mouth 31 is provided with V-arrangement rhone 35,
The bottom of filter element 2 is provided with the interior water fender 23 stretching out filter element 2, and interior water fender 23 can block V
Shape rhone 35.When interior water fender 23 blocks V-arrangement rhone 35, in water purification collecting chamber 32
Water purification just flows into water storage apparatus via water purification outlet 34, when need not collect water purification, and Ke Yizhuan
Dynamic filter element 2 makes interior water fender 23 stagger with V-arrangement rhone 35, and water purification is just via V-arrangement draining
Groove 35 is discharged from foreign material outlet 33.
In another preferred embodiment, except being provided with V-arrangement rhone 35 and interior water fender 23
Outward, the bottom of filter element 2 can also arrange outer water fender 24, interior water fender 23 and outer water fender 24
Being arranged side by side, when rotating filter element 2, interior water fender 23 and outer water fender 24 are along with together with filter element 2
Rotate.When water purification collected by needs, rotate filter element 2 and make interior water fender 23 just block V-arrangement row
Tank 35, water purification will pass through water purification outlet 34 and flows into water storage apparatus；Need not in the winter time collect only
During water, filter element 2 can be rotated and make the outer water fender 24 of filter element 2 just block the clean of lower house 3
Water outlet 34, now in water fender 23 also and then rotate together, then in water fender 23 just with V
Shape rhone 35 staggers, and rainwater is just discharged from foreign material outlet 33 via V-arrangement rhone 35, from
And prevent rainwater from entering water storage apparatus and it is produced harm.
When after the rain water filtering device a very long time using the present invention, if needing labor cleaning's annular
Filter screen 22, due to the open end of point water plate 21 detachably connected refuse collecting mouth 31, annular filter
The dismountable open end being connected to refuse collecting mouth 31 of internal ring end face of net 22, thus by filter element
2 take out and can clear up annular filter screen 22.
Those skilled in the art it should be appreciated that in order to effectively collect water purification, the rain of the present invention
The size of point water plate 21 of the umbrella of water filter should be with the size phase of the opening of refuse collecting mouth 31
Unanimously, or can also thus can guarantee that rain slightly larger than the size of opening of refuse collecting mouth 31
Water carries out filtering rather than fall directly into refuse collecting mouth 31 through drainage screen.
Embodiment described above only have expressed embodiments of the present invention, and it describes more concrete and detailed
Carefully, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, it is right
For those of ordinary skill in the art, without departing from the inventive concept of the premise, it is also possible to do
Going out some deformation and improvement, these broadly fall into protection scope of the present invention.
