## Abstract

A detergent controlling mechanism for use in a toilet is configured to have a container having a first entrance defined through an outer periphery thereof, an adjusting apparatus having a third rod threadingly connected with the outer periphery of the container, a partition which securely and sealingly separates the container into an upper portion and a lower portion, a leverage having a fulcrum pivotally connected to a bridge and securely mounted onto the partition, an inlet valve having a first rod abutting a first end of the bridge and slidably received within a chamber of a second seat, a one-way valve for directing flow only from the first part to the second part and which is sealingly mounted on a board which separates the lower portion into a first part and a second part and a releasing valve mounted onto the partition for determining an amount of detergent to be released. The controlling mechanism is thus able to release a fixed amount of detergent to a water tank every time a user flushes the toilet.

## Claims

### Claim 1

A detergent controlling means for use in a toilet comprising:
a container having a water hose securely connected thereto and a first entrance and an exit respectively mounted on an outer periphery thereof,
a partition securely dividing said container into an upper portion and a lower portion and having a leverage securely mounted thereon, said leverage being provided with a fulcrum mounted onto the partition, a bridge centrally and pivotally connected with the fulcrum,
a board sealingly and securely dividing said lower portion of said container into a first part and a second part,
an inlet valve securely mounted in said first part and onto an outer periphery of said container and having
a first rod slidably and sealingly received through said partition, and abutted to a first end of said bridge by a first end thereof,
a fourth rod having a first end abutted to a second end of said first rod, and a second end securely mounted with a cone-shaped plug which is detachably connected with said water hose,
a seat having a chamber defined therein and communicating with said water hose and a plurality of through holes defined near an outer periphery thereof and communicating with said chamber, and
a first coil spring movably received within said chamber and confined between a first end of said chamber and a first end of said cone-shaped plug,
a releasing valve securely mounted onto said partition and having
a second rod securely and sealingly connected with a second end of said bridge,
a barrel securely mounted onto said partition and having a first space and a second space defined therein; said second space is configured to have a third entrance communicating with said upper portion, a second exit and an extension tube communicating therewith, and
a second coil spring mounted around said second rod and securely confined between said first space and an under face of said bridge, and
a one-way valve securely mounted through said board and having a channel and a passage defined therein; said passage communicating with said channel,
a fourth entrance defined at a first end of said passage and communicating with said first part of said lower portion,
a stop securely mounted at a second end of said channel,
a third rod reciprocally received within said channel,
a plug securely mounted onto a first end of said third rod and having a plurality of holes defined near an outer periphery thereof, and
a third coil spring securely confined between a face of said plug and said stop.

### Claim 2 (depends on 1)

The detergent controlling means as claimed in claim 1 further comprising a first seat having a first sealing and a second sealing securely received therein, said first sealing and said second sealing being fixedly mounted around said first rod to tightly seal said first rod and said partition.

### Claim 3 (depends on 1)

The controlling means as claimed in claim 1 further comprising an adjusting apparatus securely connected on an outer periphery of said container and having a fifth rod threadingly connected therewith, a first end of said fifth rod abutting said second end of said bridge of said leverage.
