Toilet flushing water controlling device

Abstract

A toilet flushing water controlling device is used in conjunction with a reservoir and comprises a funnel part, forming a lower part of the reservoir and having a lower end with an outlet, a sealing ball for closing the outlet, placed in the reservoir, and a flushing device for displacing the sealing ball from the outlet so as to release flushing water from the reservoir. Thereby developing of germs is prevented flushing water is saved.

1 . A toilet flushing water controlling device, used in conjunction with a reservoir and comprising:
 a funnel part, forming a lower part of the reservoir and having a lower end with an outlet;   a sealing ball for closing the outlet, placed in the reservoir and having a density; and   a flushing device for displacing said sealing ball from said outlet, so as to release flushing water from said reservoir.   
   
   
       2 . The toilet flushing water controlling device of  claim 1 , wherein said density of said sealing ball is lower than density of water, so that said sealing ball, if completely submerged in water, will be displaced from said outlet. 
   
   
       3 . The toilet flushing water controlling device of  claim 1 , wherein said sealing ball has a weight w and a volume, when half of said volume of said sealing ball emerges from water, is subject to a buoyancy b 1  which is smaller than said weight w. 
   
   
       4 . The toilet flushing water controlling device of  claim 1 , wherein said flushing device is mounted on a top cover of said reservoir and comprises: a case of cylindrical shape, mounted on a lower side of said top cover and having an upper end with an outer thread; a positioning plate at a lower end of said outer thread, a lid with a central hole, set on a top side of said case; a pulling rod with a widened upper end, passing through said central hole; a helical spring, located inside said case and surrounding said pulling rod; a lower plate, attached to a lower end of said pulling rod and leaning against said helical spring from below; and a cord, connecting said lower end of said pulling rod and said sealing ball. 
   
   
       5 . The toilet flushing water controlling device of  claim 1 , wherein said flushing device comprises: a T-tube, shaped like said letter T and having an upper tube segment which is connected with said outlet, a lower tube segment which is connected with said flushing tube and a horizontal tube segment; a lever, having a lever ball forming a middle section thereof, through which an axis of rotation of said lever passes, an outer end with a handle and an inner end, which is movable between positions close to said upper tube segment and said lower tube segment; a cover, screwed on an outer end of said horizontal tube segment and having a hole, through which said outer end of said lever passes; a sealing plate, sealing a gap between said lever ball and said cover; a pushing rod, which is vertically oriented and placed inside said upper tube segment, having a lower end with a mounting hole, through which said inner end of said lever passes; at least three positioning plates, through which said pushing rod passes and thereby is stably held, with water flowing between said positioning plates; and a helical spring, placed between said positioning plates and said outlet and pushing said lever towards a normal position.
