Flushing controller for toilet

Claim 1

An improved flushing controller for a toilet comprising: a variable flushing actuator extending inwards a spindle which is connected with a lever to pull toilet flush valve by a wire; a pre-set flushing actuator having spindle formed with a central hole to freely insert said spindle of said variable flushing actuator; a fixed bushing forming with a hollow cylinder for rotatably fixing said two spindles of said variable flushing actuator and said pre-set flushing actuator on a toilet tank wall; and a vertically adjusted float formed under said fixed bushing, the improvement which comprises: said pre-set flushing actuator formed with a float engaging means which is formed with three upper extensions and a lower extension, respectively extending from said spindle of said pre-set flushing actuator and separated in equal radians, said lower extension cut with a recess to engage with a float lever; said pre-set flushing actuator formed with an extension ring formed at the rear end of said float engaging means and rotatably fixed in said fixed bushing, a bushing cover rotatably sealing said hollow cylinder of said bushing, and a rest plate extending from said bushing cover to biase said lever for valve opening; said fixed bushing formed with a hollow cylinder wherein three grooves are formed inside said hollow cylinder to limit the rotation of said three upper extensions of said float engaging means, and formed with a guide block under said engaging means, a hollow pipe for reciprocative motion of a float lever provided in said guide block; and said vertically adjusted float comprising a hollow cylinder which is partitioned traversely by a diaphragm plate to form an upper chamber filled with water and a lower chamber accumulated with air therein and centrally longitudinally formed with a central tube for free adjustment of said float lever jacketed in said central tube, and a float lever having a lever head which is formed with a tapered portion on its top end to engage with said recess of said float engaging means, whereby said pre-set flushing actuator is depressed to engage said recess of said lower extension with said float lever as backed by float buoyancy and said lever is biased by the rear rest plate to open a toilet flush valve for flushing use.
