Automatic toilet cleaning device

An automatic toilet cleaning device for automatically releasing a chemical cleaning agent into water employed to fill a toilet bowl each time a toilet is flushed, said device comprising:

• a container being comprised of a fluid impermeable material thereby enabling said container to contain a fluid cleaning agent, said container having a grapple being integrated into said container thereby enabling said grapple to grip a tank of a toilet thereby enabling said container to be suspended in said tank, said grapple having a front panel which extends upwardly from a top edge of said container which corresponds to a rear wall of said container, said grapple having a top panel being perpendicularly oriented with said front panel and a rear panel extending downwardly from and being perpendicularly oriented with said top panel having said rear panel being spaced from said front panel to enable an outer wall of said tank to be positioned between said front panel and said rear panel having said top panel resting on an upper edge of said outer wall of said tank;
• and
• a venturi valve having a fluid input and a fluid output and a mixing input being in fluid communication with each of said fluid input and said fluid output, said fluid input being in fluid communication with a fluid supply line of said toilet wherein said fluid input is configured to receive water from said fluid supply each time said toilet is flushed, said mixing input being in fluid communication with said container thereby enabling said venturi valve to receive said fluid cleaning agent in said container wherein said venturi valve is configured to mix said fluid cleaning agent with the water flowing through said venturi valve each time said toilet is flushed, said fluid output being in fluid communication with a bowl supply line of said toilet wherein said venturi valve is configured to dispense the mixture of said fluid cleaning agent and the water into said bowl supply line thereby enabling the mixture of said fluid cleaning agent and the water to be released into a bowl of said toilet for cleaning said bowl of said toilet each time said toilet is flushed, said venturi valve having a throttle being movably integrated into said venturi valve, said throttle being in communication with said mixing input for controlling an amount of said fluid cleaning agent which flows into said venturi valve between a minimum amount and a maximum amount, said venturi valve having a cylindrical body having a first end and a second end and an exterior wall extending between said first end and said second end, each of said first end and said second end being open, said venturi valve having a first nipple being attached to said first end such that said first nipple defines said fluid input, said first nipple having a series of ribs on an outer surface of said first nipple thereby enabling fluid supply line of said toilet to engage said series of ribs when said first nipple is inserted into said fluid supply line to inhibit said fluid supply line from becoming dislodged from said first nipple, said venturi valve having a second nipple being attached to said second end such that said second nipple defines said fluid output, said second nipple having a series of ribs on an outer surface of said second nipple thereby enabling said bowl supply line to engage said series of said ribs on said outer surface of said second nipple when said second nipple is inserted into said bowl supply line to inhibit said bowl supply line from becoming dislodged from said second nipple, said venturi valve having a third nipple being attached to said exterior wall of said venturi valve such that said third nipple defines said mixing input, said third nipple having a series of ribs on an outer surface of said third nipple thereby enabling a mixing line to engage said series of ribs on said outer surface of said third nipple when said third nipple is inserted into said mixing line to inhibit said mixing line from becoming dislodged from said third nipple, said mixing line extending into said container thereby enabling said third nipple to receive said fluid cleaning agent from said container, said cylindrical body having a fluid channel which extends between said first end and said second end such that said fluid channel is in fluid communication with each of said first nipple and said second nipple wherein said fluid channel is configured to enable the water from said fluid supply line to flow through said fluid channel, said cylindrical body having a mixing channel which extends through said exterior wall and intersects said fluid channel, said mixing channel being in fluid communication with said third nipple thereby enabling said mixing channel to receive said fluid cleaning agent from said mixing line, said fluid channel having a bounding surface, said bounding surface of said fluid channel having a first portion which tapers in diameter between said first end and an intersection with said mixing channel wherein said first portion is configured to increase a fluid pressure of the water which flows between said first nipple and said intersection of said mixing channel, said bounding surface of said fluid channel having a second portion which tapers in diameter between said second end and said intersection with said mixing channel wherein said second portion is configured to decrease the fluid pressure of the water which flows between said intersection of said mixing channel and said second nipple thereby creating a vacuum at said intersection of said mixing channel thereby enabling said fluid cleaning agent in said container to be drawn into said fluid channel when the water flows through said fluid channel, said intersection with said mixing channel being positioned closer to said first end than said second end, said exterior wall of said venturi valve having a pair of planar portions each being located adjacent to a respective one of said first end and said second end of said venturi valve, said exterior wall having indicia being applied to said planar portion positioned adjacent to said first end comprising the word “In”, said exterior wall having indicia being applied to said planar portion positioned adjacent to said second end comprising the word “Out”, said throttle comprising a screw which extends through said exterior wall of said venturi valve and into said intersection between said mixing channel and said fluid channel, said screw decreasing a diameter of said intersection when said screw is tightened thereby decreasing the volume of said fluid cleaning agent that can flow through said intersection, said screw increasing a diameter of said intersection when said screw is loosened thereby increasing said volume of said fluid cleaning agent that can flow through said intersection.
