According to the embodiment, a toilet device includes a toilet, a flow channel, a wash water supply unit a sensing unit and a controller. The sensing unit is configured to sense whether or not the wash water is at a position lower than a full water level and higher than a sealing water level on a surface of a bowl of the toilet. The controller is configured to determine a clogging state of the toilet based on a sensing result of the sensing unit following the closing of the wash water supply unit. A sensing region of the sensing unit is a position on the surface of the bowl through which the wash water flowing in a vertical direction from a water discharge port of the flow channel to a bottom portion of the bowl passes after the wash water supply unit is closed.

A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

A self-cleaning toilet has: a toilet, a cleaning device, a solenoid valve and a blocking member. The toilet has a sitting toilet seat and a water tank. The sitting toilet seat is formed with a urinal, and one end of the urinal has an enlarged opening to form a seat, and the urinal tapers from the seat to the other end to form a drain elbow. The water tank is connected to the toilet with an outlet pipe, and the water tank is connected with an input pipe, a cleaning device is set in the toilet with a controller, and the controller is connected with a plurality of the ultrasonic transducers and a full water level sensor, The ultrasonic transducers are fixed on the inner wall of the urinal. The solenoid valve is connected to the input pipe, and a blocking member is connected to the drain elbow.

A flush toilet includes a bowl, a tank coupled to the bowl, a flush valve positioned within the tank, and a flush device configured to initiate a flush cycle. The automatic toilet further comprises an electronic sensing assembly having a sensing member positioned on the bowl for detecting an overflow condition of the bowl, an overflow device operably coupled to the flush device, and a controller in electronic communication with the electronic sensing assembly and the overflow device for controlling the flush device in response to a condition of the toilet.

A Cover Box toilet accessory that contributes to preventive medicine, improves global health, reduces the spread of diseases, and fights the environmental pollution caused by the emission of infectious and polluting bioaerosols during toilet flushing. The Cover Box is designed to fit over the Water Flushing Button of a conventional toilet and includes a Fixed Base and a Sliding Top with transparent or translucent parts. The Fixed Base includes Fitting Guides and a tension spring. By obstructing the direct access to the Water Flushing Button, this Cover Box forces the user to close the toilet lid before flushing, since the movement of the Sliding Top to reveal the button also indirectly closes the toilet lid, reducing the emission of bioaerosols that can spread diseases and cause environmental pollution. The system has a high global impact and can be used in various settings, having a significant impact on public health.

A toilet flushing system comprising a cylindrical receiver into which flush water is received through a fill valve; a float operating within a float chamber that is fluidly connected to said cylindrical receiver to open and close said fill valve according to the water level in said cylindrical receiver; and a displacer rotatably attached to an axis inside said cylindrical receiver to displace any required fraction of water from said cylindrical receiver into a bowl relative to the angle of rotation.

A system for preventing overflow of a toilet includes a capacitance sensor arrangement as in combination with certain features (e.g., flap valve disablement). The system can detect an overflow flush condition of a toilet by sensing the value of a parameter of one or more normal flush cycles of the toilet and establishing a normal range for the value of the parameter using the sensed value. The system can also store the normal range in a memory for comparison to a value of the parameter during subsequent flush cycles. The system can perform sensing over a predetermined timeframe. The system can include the time frame being sufficient to include the entire push cycle of the toilet.
