Abstract
The present invention relates to apparatus for washing drains. The apparatus includes a support and a nozzle, which are adapted and configured to convey fluid to and to wash a drain. Typically, the apparatus includes a wand as the support and a ball or head as the nozzle. The apparatus can also include a fluid retainer, which can keep the dispensed fluid in and/or near the drain.
Claims34
A drain washing apparatus comprising ball, shield, and wand;
- the wand having proximal end and distal end;
- the ball being coupled to the wand at the distal end;
- the wand and ball being adapted and configured to provide fluid flaw through or along the wand and through the ball;
- the ball being adapted and configured to nest with a drain;
- the shield being coupled to the wand at the distal end and proximal of the ball;
- the shield extending radially from the wand;
- and
- the shield having a radial dimension greater than a diameter of a drain;
- wherein the shield defines a cavity proximal the ball and comprises a contact portion spaced radially from the ball;
- wherein the shield comprises housing, the housing being adapted and configured to retain the ball;
- wherein the housing comprises cylinder and flange:
- the cylinder defining a cavity occupied by at least a portion of the ball and having a proximal end and distal end;
- the flange surrounding at least a portion of the proximal end of the cylinder and being adapted and configured to prevent the ball from protruding through the proximal end of the cylinder.
