Abstract

Disclosed are various embodiments of a garbage disposal cleaning brush. The brush can include a brush head, a splash guard, and a rod. The splash guard can include a shaft, a circular channel well and a lip extending from the outer wall of the circular channel well. The rod may be connected to the brush head and extending through the shaft of the splash guard. The shaft can include a first inner wall and a first outer wall. The circular channel wall can include a hold on a bottom surface, a second inner wall, and a second outer wall.

First claim

Therefore, the following is claimed:

1. An apparatus comprising:
a brush head;
a splash guard comprising:
a shaft comprising a first inner wall and a first outer wall;
a circular channel well surrounding the shaft, the circular channel well comprising:
a hole on a bottom surface of the circular channel well,
a second inner wall, and
a second outer wall; and

a lip extending radially outward from the second outer wall of the circular channel well, the lip comprising a rim that extends radially outward from the lip; and

a rod connected to the brush head, the rod extending through the shaft of the splash guard.

2. The apparatus of claim 1 , wherein the second inner wall of the circular channel well forms at least a portion of the first outer wall of the shaft.

3. The apparatus of claim 1 , wherein the shaft further comprises a plurality of elongated protrusions that extend along a portion of a length of the first inner wall of the shaft.

4. The apparatus of claim 1 , wherein the hole on the bottom surface of the circular channel well further extends up the second inner wall.

5. The apparatus of claim 1 , wherein the hole on the bottom surface of the circular channel well further extends to the second outer wall.

6. The apparatus of claim 1 , wherein the rod comprises a first end and a second end, wherein the first end is connected to the brush head and the second end comprises a shank.

7. The apparatus of claim 6 , wherein the shank comprises a hex shank.

8. The apparatus of claim 6 , further comprising a removable handle connected to the shank of the rod.

9. The apparatus of claim 1 , wherein the lip of the splash guard further comprises:
an outer edge; and
a circular groove positioned between the outer edge of the lip of the splash guard and the second outer wall of the circular channel well.

10. The apparatus of claim 9 , wherein:
the bottom surface of the circular channel well is a first bottom surface;
the circular groove is a first circular groove located on a top surface of the lip; and
the lip further comprises a second circular groove located on a second bottom surface of the lip, the second circular groove being positioned between the outer edge of the lip of the splash guard and the second outer wall of the circular channel well.

11. The apparatus of claim 10 , wherein the first circular groove is positioned between the outer edge of the lip of the splash guard and the second circular groove.

12. The apparatus of claim 10 , wherein the first circular groove is positioned between the second circular groove and the second outer wall of the circular channel.

13. A device comprising:
a brush head;
a splash guard comprising:
a shaft comprising a first inner wall and a first outer wall;
a circular channel well surrounding the shaft, the circular channel well comprising:
a hole on a first bottom surface of the circular channel well,
a second inner wall, and
a second outer wall that extends to the bottom surface, the bottom surface being an external surface of the splash guard; and

a lip extending radially outward from the second outer wall of the circular channel well, the lip comprising:
a second bottom surface;
an outer edge;
a first circular groove located on a top surface of the lip and positioned between the outer edge of the lip and the second outer wall of the circular channel well; and
a second circular groove located on the second bottom surface of the lip and positioned between the outer edge of the lip and the second outer wall of the circular channel well; and

a rod connected to the brush head, the rod extending through the shaft of the splash guard.

14. The device of claim 13 , wherein the first circular groove is positioned between the outer edge of the lip of the splash guard and the second circular groove.

15. The device of claim 13 , wherein the first circular groove is positioned between the second circular groove and the second outer wall of the circular channel.

16. The device of claim 13 , wherein the rod comprises:
a first end connected to the brush head; and
a second end comprising a shank.

17. The device of claim 16 , further comprising a removable handle connected to the shank of the rod.

18. The device of claim 13 , wherein the second inner wall of the circular channel well forms at least a portion of the first outer wall of the shaft.

19. A garbage-disposal cleaning brush comprising:
a brush head;
a splash guard comprising:
a shaft comprising:
a first inner wall;
a first outer wall; and

a circular channel well surrounding the shaft, the circular channel well comprising:
a second inner wall forming at least a portion of the first outer wall of the shaft;
a second outer wall that extends to a bottom surface, the bottom surface being an external surface of the splash guard; and
a hole on the bottom surface of the circular channel well, the hole extending up the second inner wall and to the second outer wall; and

a lip extending radially outward from the second outer wall of the circular channel well, the lip comprising:
an outer edge; and
a circular groove positioned between the outer edge of the lip of the splash guard and the second outer wall of the circular channel well; and

a rod connected to the brush head, the rod extending through the shaft of the splash guard.

20. The garbage-disposal cleaning brush of claim 19 , wherein the rod comprises:
a first end connected to the brush head; and
a second end comprising a shank.
