Disclosed is an in-the-bowl dispensing device designed to dispense a composition after the flush of the toilet bowl is complete. In this manner the composition is retained in the toilet bowl until the toilet bowl is flushed by the next user.

A device is provided for cleaning a toilet having a toilet bowl, the device including a treatment unit including a housing having a cavity configured and enabled to collect and store flushing tank fluids of said toilet flowing via one or more openings in said housing, one or more cleaning materials, a spraying unit including one or more spraying devices, wherein the spraying devices are configured and enabled to spray said flushing tank fluids mixed with the cleaning materials via the one or more spraying devices into an interior of the toilet bowl, one or more pumps for drawing the flushing tank fluids mixed within the treatment unit with the one or more cleaning materials to the spraying unit.

A chemical dispensing system for a toilet that includes a container configured to contain a chemical compound that mixes with water to form a cleaning compound; a bracket coupled to the container; a threaded protrusion that extends from the bracket and is configured to extend through a hole in an inside of the sidewall of the toilet; and a fastener having a threaded body and a head, which is larger radially than the threaded body such that the head is configured to contact an outside of the sidewall in a secured position in which the threaded body threads to the threaded protrusion.

The present disclosure relates to a method carried out by a sensor device arranged in and/or on a toilet bowl. The method includes the steps of detecting, by a sensor of the sensor device, at least one first environmental parameter in an environment of the sensor device with the first environmental parameter being characteristic of a cleanliness of the toilet bowl, and determining and/or effecting the determination of an item of control information by the sensor device at least partly depending on the detected first environmental parameter.

An automatic flushing squatting toilet includes a toilet body and a water tank. Flushing mechanisms are disposed inside the toilet body. The flushing mechanisms include installing grooves disposed on an upper wall of the toilet body. An inner wall of each installing groove close to an upper end of each installing groove is fixedly connected with a respective flexible plate. Each installing groove is fixedly connected with a respective piezoelectric plate. A lower wall of each flexible plate is fixedly connected with a respective pressing block. Each pressing block contacts a corresponding piezoelectric plate. Water sucking cavities are disposed inside the toilet body. Each water sucking cavity is fixedly connected with a metal plate. Each water sucking cavity is elastically connected with a respective electromagnetic plate through a respective return spring. Each electromagnetic plate is slidably connected with each water sucking cavity.

A extended-time release method includes the following steps: mixing water with the toilet cleaner to form an initial solution when water enters a bowl; starting release of the initial solution while water level in the bowl returns to normal; and continuing release of the initial solution after the water level in the bowl returns to normal, in which a mixed liquid of the initial solution and the water in the bowl is referred to as a primary solution; in the above method, the volume of the initial solution is not less than 10 ml; and the content of the effective ingredients of the toilet cleaner in the primary solution is not less than 2 ppm.

A urinal and pipe cleaning composition and automated dispensing system and method. The composition preferably comprises urea hydrochloride, a thickener, optionally one or more surfactants, and optionally fragrance. Preferably, the surfactants comprise cocamidopropyl betaine and one or more ethoxylated alcohols. The composition preferably has a viscosity allowing it to be dispensed from an automated dispenser and to coat the surfaces to be cleaned to allow sufficient contact time to dissolve accumulated salts and remove stains. A predetermined dose of the composition is dispensed at predetermined time intervals. Different dose amounts and time intervals may be used depending on the level of usage of the urinal, the amount of salt scale, and level of staining.

This disclosure relates to systems, methods, and compositions for dispensing multiple compositions into a plurality of containers or atmospheres. In one embodiment, this disclosure pertains to treating and preventing offensive odors arising from toilets. The system includes a base station with at least one bag-on-valve (BOV) canister, which holds one or more compositions. A tube leads from the output of the bag-on-valve canister to a bowl clip and/or to a spray nozzle. The bowl clip can be mounted to a toilet bowl. One example embodiment of the invention includes a bowl clip with a sensor that initiates release of the composition(s) from the bag-on-valve (BOV) canister(s), while another embodiment initiates release of the composition(s) from the bag-on-valve (BOV) canister(s) using a motion sensor or activation switch. The compositions are delivered to treat and prevent offensive odors.

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.
