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 fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.

A powerless automatic flushing device is proposed. The device controls flushing of feces and time to dispose of toilet paper with feces while suctioning air from outside through a feces toilet paper time adjustment part and a flushing adjustment part when a toilet user defecates and leaves a toilet seat, and respectively controls the flushing of urine and time to dispose of toilet paper with urine while rapidly suctioning the air from the outside through each of a feces toilet paper time adjustment part, a flushing adjustment part, and a urine toilet paper time adjustment part when the toilet user urinates and leaves the toilet seat, thereby preventing the toilet user from wasting the water by unnecessarily pressing a lever, and a tension load spring compresses in conjunction with descending motion of the toilet seat and retains a tension load force capable of pulling a flushing wire.

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.

An actuation apparatus (1) for a functional device, having a pressure actuation element (2) for carrying out a pressing movement which is connected to an axially displaceable control element (3), wherein the control element (3) includes an application location (4) which can be moved into an active connection with the functional device or which is in an active connection with the functional device in the position for use. At least one compensation element (5) is arranged or constructed between the pressure actuation element (2) and the application location (4), and the compensation element (5) allows a position change of the pressure actuation element (2) relative to the application location (4) in a radial direction (6).

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.

Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float. The moveable float can form a fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and a flow opening when the moveable float is at least partially decoupled from the outlet base. Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.

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.
