Patent ID: 8695125

Claim:
An automatic toilet flushing system and a toilet, the toilet having a reservoir tank and a toilet bowl, the system comprising: a sensor for sensing the approach and departure motion of a user with respect to the toilet and for generating a signal representative of the approach and departure motion of the user; an actuator in communication with the sensor for causing an automatic flushing of the toilet in response to the signal from the sensor, the actuator comprising: a driven pivotal arm; a gear train; a motor having a first output shaft rotatably connected to the gear train; a second shaft pivotally connected to the gear train and to the pivotal arm of the actuator; and a power source for activating the motor and for rotating the first output shaft of the motor which rotates the gear train for the pivotal movement of the pivotal arm; and a flushing mechanism co-acting with the actuator, wherein the flushing mechanism includes a flapper valve adapted to release water from the reservoir tank, wherein the pivotal arm of the actuator is connected to the flapper valve for operation of the flapper valve upon the pivotal movement of the pivotal arm, and wherein said actuator further includes an actuator box for housing the actuator and wherein the actuator box comprises: a first compartment for supporting the power source, a second compartment for supporting the gear train and the motor, wherein the second compartment is separate from the first compartment, a first cover for covering and sealing the first compartment, having a first edge a second cover for covering and sealing the second compartment, having a second edge wherein the second cover is separate from the first cover, and where the first edge is only adjacent to the second edge, a first sealing member inserted between the first cover and the first compartment for sealing the first compartment, a second sealing member inserted between the second cover and the second compartment for sealing the second compartment, and wherein the first compartment and the first cover fully enclose the power source and wherein the second compartment and the second cover fully enclose the gear train and the motor.
