    Abstract: 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 detectable 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.

The solar board is disposed near a light source for converting light into electricity and is electrically connected with the outlet valve body via a guiding line, facilitating to a normal operation of a sensor and an electromagnetic valve inside the outlet valve body. For the outlet valve body, the use of batteries or an electrical connection with any commercial powers is unnecessary for reducing the energy consumption and environmental sufferings.

  • Patent number: 8234724
    Abstract: A multi flush volume flush valve is in communication with an automatic flush control. The flush control determines the presence of a user and the amount of time the user uses the toilet. The usage time is compared to a predetermined time value to determine the appropriate flush volume based on an assumption regarding usage time and flush volume needs. The comparative value statistically adjusts to the restroom traffic.

  • Patent number: 8205275
    Abstract: An external automatic flush helper comprises a housing and fixing means for fixing the housing onto a toilet tank. Within the housing there are provided with a DC power supply, a controller powered by the DC power supply, an infrared sensor and a motor connected with the controller, and an actuating mechanism connected with the motor. An end actuator of the actuating mechanism is arranged in alignment with the button of the toilet tank. The end actuator can be actuated and move out of an opening in the housing when a user status is detected by the infrared sensor, and thus press the button of the toilet tank. Therefore, automatic flushing can be achieved contactlessly.

  • Patent number: 8095997
    Abstract: A modular cartridge based liquid dispensing system for automatically dispensing a metered amount of liquid(s) into a toilet water tank and/or bowl. This unique programmable system mounts onto a standard water tank, and is shaped to match the tank so that it blends well with the existing toilet design for aesthetics. It is designed to dispense one or a plurality of solution types, allowing any desired solution to be dispensed, such as cleaning solutions and deodorants. It uses replaceable liquid cartridges that can be refillable or disposable, and can also use fixed tanks. This invention can also utilize all of its components in a low-rise cabinet chassis that allows the entire system to be mounted inside the water tank where it is completely hidden from view. The system also has provisions for an optional automatic toilet flushing device and can also be used to dispense its liquids to a bidet apparatus.

  • Publication number: 20110302708
    Abstract: An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

  • Patent number: 8020221
    Abstract: In one aspect, the present invention is directed to a toilet seat lifting device (10), comprising a pneumatic system employing a piston (48) connected to the toilet seat (6), the system being adapted to lift the toilet seat (6) by applying mechanical force on the piston (48) in the corresponding direction (upwards, in the example herein), and to gradually lowering the toilet seat by gradually releasing air from the pneumatic system. The device may further comprise a valve (56), for causing a fall in air pressure in the pneumatic system, thereby causing an accelerated lowering of the toilet seat. The device may further comprise: a sensor, for sensing lowering of toilet seat (6); and a mechanism for activating flushing the toilet bowl upon detecting by the sensor that the seat has been lowered, such as a handle of a tap providing water to the flush tank (8) thereof.
