Particle trap/filter and systems related thereto

1. A filter comprising:

a main body with a planar top surface and planer bottom surface; and,

a plurality of passages that pass continuously through the body wherein the passages have outer walls with a larger diameter cross-section that extends above the top surface and a smaller diameter cross-section that extends below the bottom surface.

2. The filter of claim 1 , wherein the passages, including the outer walls, have a funnel shaped section.

3. The filter of claim 1 , wherein the top of each passage, including the outer walls, is a straight round section that forms a cylinder that transitions into a funnel shaped section.

4. The filter of claim 1 , wherein the passages are arranged in concentric circles radiating out from a center of the filter.

5. The filter of claim 1 , further comprising a plurality of legs that extend from the body down below a bottom of the passages.

6. The filter of claim 5 , wherein each of the plurality of legs is also a funnel shaped passage.

7. The filter of claim 6 , wherein a subset of the plurality of legs further include holes in their sidewalls below the body.

8. The filter of claim 1 , further comprising a plurality of holes through the body and located in between the passages.

9. The filter of claim 8 , wherein the holes are funnel shaped.

10. The filter of claim 1 wherein the filter is made from injection molded plastic.

11. A filter comprising:

a plurality of passages all oriented parallel to each other wherein the passages have outer walls that form a circular top with a first outer diameter and a circular bottom with a second smaller outer diameter and a portion in between the top and the bottom that is funnel shaped;

a body that couples each of the plurality of passages together such that the outer walls extend above and below the body.

12. The filter of claim 11 , wherein the passages are arranged in concentric circles radiating out from the center of the body.

13. The filter of claim 11 , wherein the top of each passage is a straight round section that forms a cylinder that transitions into a funnel shaped section.

14. The filter of claim 12 , further comprising a plurality of legs that extend from the body down below a bottom of the passages.

15. The filter of claim 14 , wherein each of the plurality of legs is also a funnel shaped passage.

16. The filter of claim 15 , wherein a subset of the plurality of legs further include holes in their sidewalls below the body.

17. The filter of claim 11 , further comprising a plurality of holes through the body and located in between the passages.

18. The filter of claim 17 , wherein the holes are funnel shaped.

19. A system for separating dirt from a cleaning liquid comprising: the filter of claim 11 ; and, a bucket with an inner diameter designed to receive the outer diameter of the filter.

20. The system of claim 19 , further comprising a seal designed to seal the filter to the bucket.

21. The filter of claim 1 , wherein the plurality of passages are placed with respect to the body such that 10% or less of a length of a passage extends above the body.

22. The filter of claim 1 , wherein the passage, including the outer walls, is cylindrically shaped above the body and has a funnel shaped section below the body.

23. The filter of claim 11 , wherein the plurality of passages are placed with respect to the body such that 10% or less of a length of a passage extends above the body.

24. The filter of claim 11 , wherein an outer edge of the body is round and wherein the tops of the plurality of passages form a plane and wherein the body is sloped with respect to the plane from the outer edge of the body to a center of the body.

25. The filter of claim 11 , wherein an outer edge of the body is round and wherein the tops of the plurality of passages form a plane and wherein the body is sloped with respect to the plane from a center of the body towards the outer edge of the body.
