Anti-splash device for fixtures

Abstract

A drain cover is provided having an anti-splash device and an enclosure for containing the deodorant block. The enclosure projects upwardly from a drain cover. The anti-splash device projects upwardly from the enclosure so that the anti-splash device is disposed above the top surface of the enclosure.

1 . An anti-splash urinal drain cover, comprising; 
 a base configured to overlie the drain of a urinal;    an enclosure projecting upwardly from the base comprising 
 at least one wall projecting upwardly from the base;  
 a top surface forming a cover over a chamber formed by the at least one wall, wherein the enclosure is configured so that the diameter of the chamber is greater than the height of the chamber and the chamber is configured to receive a deodorant block; and  
 one or more openings to allow fluid flow through the enclosure; and  
   a rotatable splash-reducing element connected to the top surface of the enclosure and projecting upwardly from the top surface, wherein the splash-reducing element is configured to impede splashing of fluid back toward the source of a stream of fluid.    
   
   
       2 . The device of  claim 1  wherein the rotatable splash-reducing element comprises a plurality of blades connected to a shaft, wherein the blades are rotatable in response to contact with the stream of fluid.  
   
   
       3 . The device of  claim 2  wherein each of the plurality of blades has a surface forming an angle relative to the axis of the shaft.  
   
   
       4 . The device of  claim 2  wherein the plurality of blades are rotatable relative to the shaft.  
   
   
       5 . The device of  claim 1  wherein the splash-reducing element is configured to rotate in response to the force of a stream of fluid against the splash-reducing element.  
   
   
       6 . The device of  claim 2  wherein each blade forms an angle with the axis of the shaft of between zero degrees and ninety degrees.  
   
   
       7 . The device of  claim 6  wherein each blade forms an angle with the axis of the shaft of between 45 degrees and 60 degrees.  
   
   
       8 . The device of  claim 1  comprising a deodorant block disposed within the chamber.  
   
   
       9 . An anti-splash drain cover, comprising: 
 a base configured to overlie a drain;    an enclosure projecting upwardly from the base, wherein the enclosure comprises an internal chamber configured to receive a deodorant block and a plurality of opening to allow fluid flow through the enclosure; and    a displaceable splash-reducing element connected to a top surface of the enclosure and projecting upwardly from the top surface, wherein the displaceable element is configured to impede splashing of fluid back toward the source of a stream of fluid.    
   
   
       10 . The device of  claim 9  wherein the rotatable splash-reducing element comprises a plurality of blades connected to a shaft, wherein the blades are rotatable in response to contact with the stream of fluid.  
   
   
       11 . The device of  claim 10  wherein each of the plurality of blades has a surface forming an angle relative to the axis of the shaft.  
   
   
       12 . The device of  claim 10  wherein the plurality of blades are rotatable relative to the shaft.  
   
   
       13 . The device of  claim 9  wherein the splash-reducing element is configured to rotate in response to the force of a stream of fluid against the splash-reducing element.  
   
   
       14 . The device of  claim 10  wherein each blade forms an angle with the axis of the shaft of between zero degrees and ninety degrees.  
   
   
       15 . The device of  claim 14  wherein each blade forms an angle with the axis of the shaft of between 45 degrees and 60 degrees.  
   
   
       16 . An anti-splash drain cover, comprising: 
 a base configured to overlie a drain;    an enclosure projecting upwardly from the base, wherein the enclosure comprises an internal chamber configured to receive a deodorant block; and    a splash-reducing element connected to a top surface of the enclosure, wherein the splash-reducing element is configured to impede splashing of fluid back toward the source of a stream of fluid;    wherein the splash-reducing element is positioned and configured to overlie any continuous surface on the top surface of the enclosure having a width of approximately ¼ inch or greater.    
   
   
       17 . The drain cover of  claim 16  wherein a continuous surface having a width of approximately ¼ inch or greater is formed at an intersection of the splash reducing element and the top surface of the enclosure and the remaining portion of the top surface is substantially devoid of continuous surfaces having a width of approximately ¼ inch or greater.  
   
   
       18 . The drain cover of  claim 16  wherein the splash-reducing element comprises a rotatable element.  
   
   
       19 . The drain cover of  claim 18  wherein the top surface of the enclosure has a width and the rotatable element has a diameter that is at least approximately ⅓ of the width of the top surface.  
   
   
       20 . The drain cover of  claim 16  wherein the splash-reducing element is a single moveable element projecting upwardly from the top surface from the approximate center of the top surface.
