     BACKGROUND OF THE INVENTION 
     Various types of toilet flushing devices are known in the prior art. However, what is needed, and what the present device provides, is an automatic toilet flush device including a weight sensor between a toilet bowl rim and a toilet seat and a capacitive touch plate disposed on the toilet lid, both of which are configured to automatically flush a toilet either when someone sits on the toilet seat or touches the capacitive touch plate, respectively. The weight sensor is in operational communication with a sensing module transmitter which in in wireless communication with a flush module receiver in operational communication with a microprocessor disposed within a housing inside the toilet tank. The capacitive touch plate is also in operational communication with the microprocessor, to which a timer is connected to permit flushing after a pre-determined time. When the microprocessor activates the flush module receiver, the flush motor activates an arm on a flush lever which, in turn, controls the flush valve to flush the toilet and to re-fill the toilet bowl. 
     FIELD OF THE INVENTION 
     The present invention relates toilet flushing devices, and more particularly, to an automatic toilet flush device. 
     SUMMARY OF THE INVENTION 
     The general purpose of the present automatic toilet flush device, described subsequently in greater detail, is to provide an automatic toilet flush device which has many novel features that result in an automatic toilet flush device which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof. To accomplish this, the present automatic toilet flush device is provided to flush a toilet without the presence of a manually-operated handle lever. The present device includes a flush valve disposed on a bottom end of a toilet tank of a toilet and a flush lever, within the toilet tank, which is in operational communication with the flush valve. A flush motor is disposed within the toilet tank and is in operational communication with the flush lever. A flush module receiver, disposed within a tank of the toilet, is in operational communication with the flush motor. A microprocessor, disposed within an impermeable housing, is in operational communication with the flush module receiver. A timer, disposed on the microprocessor, is in operational communication with the microprocessor. A capacitive touch plate within a lid of the toilet is in operational communication with the microprocessor. A sensing module transmitter, disposed on a rear portion of a toilet bowl of a toilet, is in operational communication with the flush valve. The sensing module transmitter is further in wireless operational communication with the flush module receiver. A weight sensor, disposed on an upper rim of the toilet bowl, is in operational communication with the sensing module transmitter. At least one battery is disposed within the toilet bowl to provide a power source to the sensing module transmitter. When the weight sensor detects weight thereon in addition to a weight of a toilet seat which is atop the weight sensor when the toilet seat is down and, alternately, when the capacitive touch plate is activated, the weight sensor activates the sensing module transmitter. Upon activation of the sensing module transmitter, the sensing module transmitter activates the flush module receiver. Subsequent to a predetermined time set on the timer from a deactivation of the weight sensor and, alternately, subsequent to the activation of the capacitive touch plate, the microprocessor activates the flush motor receiver and then the flush motor receiver activates the flush motor. Upon activation of the flush motor, the flush motor lifts an arm on the flush lever. Upon the lifting of the arm, the flush valve is opening, an water within the toilet bowl flows out and an amount of clean water from a water source flows into toilet bowl. Upon the proper filling of the toilet bowl with the clean water, the water flowing out of the toilet bowl enters and flows out of an S trap disposed underneath the toilet bowl. Thus has been broadly outlined the more important features of the present automatic toilet flush device so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     With reference now to the drawings, and in particular  FIGS. 1 through 6  thereof, an example of the instant automatic toilet flush device employing the principles and concepts of the present automatic toilet flush device and generally designated by the reference number  10  will be described. 
     Referring to  FIGS. 1 through 6  the present automatic toilet flush device  10  for use with either public toilets, such as toilets in restaurants, hospitals, and commercial structures, or residential toilets is illustrated. The automatic toilet flush device  10  includes a flush valve  20  disposed on a bottom end of a toilet tank of a toilet. A flush lever  23 , disposed within the toilet tank, is in operational communication with the flush valve  20 . A flush motor  26  is disposed within the toilet tank and in operational communication with the flush lever  23 . A flush module receiver  29  is disposed within a tank of the toilet. The flush module receiver  29  is in operational communication with the flush motor  26 . A microprocessor  32  is disposed within an impermeable housing  33 . The microprocessor  32  is in operational communication with the flush module receiver  29 . A timer  35  is disposed on the microprocessor  32 , the timer  35  further is in operational communication with the microprocessor  32 . A capacitive touch plate  40  is disposed within a lid of the toilet, the capacitive touch plate  40  is in operational communication with the microprocessor  32 . The flush motor  26 , the flush module receiver  29 , the microprocessor  32 , the timer  35 , and the capacitive touch plate  40  are powered by a power supply  45 . A sensing module transmitter  50  is disposed on a rear portion of a toilet bowl of a toilet, the toilet having a flush valve  20  and a flush lever  23  is disposed with a tank of the toilet, the flush lever  23  is in operational communication with the flush valve  20 , the sensing module transmitter  50  is in wireless operational communication with the flush module receiver  29 . A weight sensor  55  is disposed on an upper rim of the toilet bowl, the weight sensor  55  is in operational communication with the sensing module transmitter  50 . At least one battery  60 , disposed within the toilet bowl, is configured to provide a power source to the sensing module transmitter  50 . When the weight sensor  55  detects weight thereon in addition to a weight of a toilet seat which is atop the weight sensor when the toilet seat is down and, alternately, when the capacitive touch plate  40  is activated, the weight sensor  55  activates the sensing module transmitter  50 . Upon activation of the sensing module transmitter  50 , the sensing module transmitter  50  activates the flush module receiver  29 .

Upon activation of the flush motor  26 , the flush motor  26  lifts an arm  65  on the flush lever  23 . Upon the lifting of the arm  65 , the flush valve  20  is opening, and water within the toilet bowl flows out and an amount of clean water from a water source flows into toilet bowl. Upon the proper filling of the toilet bowl with the clean water, the water flowing out of the toilet bowl enters and flows out of an S trap disposed underneath the toilet bowl.
