Power generation devices and methods for use with toilets is disclosed. A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable toilets that are off the grid. The power generation devices and methods include, for example, using a cell battery inside a toilet water source, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.

The invention relates to a toilet device for the measurement of micturition parameters, the toilet device comprising a housing that has a housing opening for receiving urine and a capacitive sensor for the time-dependent, contactless measurement of micturition parameters. The invention also relates to a method for the contactless measurement of micturition parameters in a toilet device, said method being carried out more particularly using the toilet device according to the invention.

A toilet apparatus comprising a toilet bowl with a drain passageway, and a mounting support base, a wax ring having a central opening disposed below the mounting support base, the wax ring is supported on an annular clog saver plate member having a central opening with an annular wall portion, a mounting flange plate supporting the annular clog saver plate member with an extending portion for sealing a sewer passageway. The annular wall portion includes a plurality of clog saver fins attached thereto. These clog saver fins are used to catch non-passable feminine hygiene items, disposable pampers, packaging, and clothing to prevent a sewer blockage, and removal therefrom without removing the toilet bowl, while allowing passable feminine hygiene items, fluid, tissue, toilet liners, and waste material to pass through the central openings in the wax ring, clog saver plate member and mounting flange plate, and into the sewer passageway.

A waste drain system is configured to be coupled to a toilet. The waste drain system includes a conduit including a main body defining an internal passage having a central longitudinal axis, and one or more cutting blades extending from the main body toward the central longitudinal axis. The one or more cutting blades are configured to cut one or more items that pass through the internal passage.

An analytical toilet comprising a bowl for receiving excreta from a user; a base supporting the bowl; a supply of flush water; and a plurality of receptacles, each providing mechanical attachment, a power supply, and a data connection to an analytical device, which analytical device is adapted to provide data useful to the user is disclosed.

Disclosed are devices, methods, and systems for generating and applying a magnetic field in a toilet. A toilet including a bowl having a discharge outlet, a trapway in fluid communication with the discharge outlet, and at least one magnet configured to generate a magnetic field to alter a flow of liquid through the trapway is described.

A foaming device comprises a valve body, a pump, and a self-suction spray head. The valve body comprises a water inlet port, a liquid inlet port, a mixing cavity, and a liquid outlet port. Each of the water inlet port, the liquid inlet port, and the liquid outlet port is in communication with the mixing cavity, and an input end of the pump is connected to the liquid outlet port to enable the mixing cavity to generate a negative pressure to suck water and foaming agent respectively from the water inlet port and the liquid inlet port for mixing. The self-suction spray head is connected to an output end of the pump, and the self-suction spray head comprises a first air inlet hole and a spray hole to enable mixed liquid to be mixed with air to produce foam to be sprayed out.

An excreta sample capture device includes a primary influent pipe that receives influent from a toilet(s) and includes an upstream end and a downstream end. The excreta sample capture device also includes a first valve positioned at the downstream end of the primary influent pipe, and a second valve positioned between the upstream end and the downstream end of the primary influent pipe. In some cases, an excreta sample capture device further includes spray jet positioned above the second valve and a sample extraction vessel located downstream from the second valve. A method of using an excreta sample capture device includes receiving influent in the primary influent pipe, initiating a closing of the first valve, opening the second valve, and capturing a sample of the excreta.

A toilet for measuring excreta is disclosed. The toilet is adapted to measure the amount of excreta received by the bowl and then the flush water. A pressure sensor is configured to monitor the pressure exerted by the flush water and any excreta contained therein. Data from monitoring the pressure of the flush water and excreta therein is used to determine the weight or volume of the excreta received by the bowl. This toilet can provide data which may be used to analyze how the volume of flush water changed due to excreta deposit. A volume change feature can be associated with a urination event and the data associated with the event can be used to determine a urine characteristic of the event.
