1. An automatic flushing system,adapted to be installed within a tank of a toilet, the automatic flushing system comprising:
- sensing means for detecting the toilet usage, generating and sending an actuating signal;
driving means for receiving said actuating signal to actuate a latching means;
said latching means for engaging and releasing a buoyancy means;
said buoyancy means for applying buoyancy of water in the tank to an actuating means, wherein said buoyancy means comprises a float;
said actuating means for unseating and seating a valve means with the help of said buoyancy means; and
said valve means adapted to a drain of the tank so as to open the drain by said actuating means, wherein said latching means releases said float, the force for opening of said drain of the tank is solely provided by the buoyancy force of said float.

Abstract
An automatic flushing system is equipped with a buoyancy mechanism to unseat a valve set in a tank of a toilet. The automatic flushing system, equipped with battery power, includes sets of sensing, actuating, latching, buoyancy, unseat/seat and valve members. The battery power only provides electrical power to sensing and actuating members to release a float from an engaged position to a release position. Thus, the buoyancy of the float may unseat a valve to open a drain of the tank.

11. An automatic flushing system, adapted to be installed within a tank of a toilet, the automatic flushing system comprising:
-
sensing means for detecting the toilet usage, generating and sending an actuating signal; a set of rotary members and receivers for receiving said actuating signal to actuate a pivotal member;
said pivotal member adapted to pivot on a central shaft;a stop shaft fixed on said pivotal member and arranged in an offset position to said central shaft on said pivotal member; a latch lever adapted to be urged away from said central shaft by said stop shaft when said pivotal member is driven to pivot and said stop shaft attaches to said latch lever; a first gear pivotally fixed in the tank, said first gear adapted to pivot when said latch lever is at a release position away from said central shaft; a float; a guiding member fixed on said first gear and used as joint said float, wherein said float emerges out of water when said latch lever is at said release position; a second gear pivotally fixed in the tank, said second gear adapted to engage said first gear and pivot when said latch lever is at said release position; a jointer to connect said valve means; a member pivotally fixed on said second gear and unseats said valve means when said latch lever is at said release position; said valve means adapted to a drain of the tank so as to open the drain by said actuating means, wherein the force for opening of said drain of the tank is solely provided by the buoyancy force of said float; and a battery-power set to provide said sensing means and said pivotal member with electric power.
