Automatic toilet flush device

Abstract

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 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.

DETAILED DESCRIPTION OF THE DRAWINGS

(7) 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.

(8) 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. Subsequent to a predetermined time set on the timer 35 from a deactivation of the weight sensor 55 and, alternately, subsequent to the activation of the capacitive touch plate 40, the microprocessor 32 activates the flush motor 26 receiver and then the flush motor 26 receiver activates the flush motor 26. 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.
