A solution supply comprises a container having a space and a channel socket in the space to allow the solution to flow out of the container, the container floated by buoyance in a water tank and a feeder opening or closing the channel socket by buoyance and gravity in the water tank, wherein the feeder includes a dispenser having an upper portion and a lower portion, and wherein the upper portion of the dispenser includes a coupling body having an upper portion assembled with the channel socket along the same axis as the channel socket and moved by the buoyance of the container, and the lower portion of the dispenser includes a weight center base supporting the coupling body and a shutter stem coupled with an upper portion of the weight center base and having a stem seal for opening and closing to the channel socket.

An electro-chlorinating device includes a housing and a pair of electrodes. The housing comprises a reservoir; an inlet port fluidly coupled to the reservoir; and a discharge device fluidly coupled to the reservoir. The discharge device is configured to be fluidly coupled to a plumbing product. The discharge device is configured to release a fluid from the reservoir into the plumbing product in response to a movement of water through the plumbing product. The pair of electrodes is coupled to the housing such that at least a portion of each electrode of the pair of electrodes is disposed within the reservoir.

Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir; a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.

A liquid dispenser is provided including a housing having an inlet port connectable to a liquid container, an outlet port configured to be in fluid communication with toilet tank, and a piston slidably mounted in the housing and selectively displaceable between a suction position in which the piston is displaced away from the inlet port thereby allowing suction of cleaning liquid through the inlet port and an injection position in which the piston is urged towards the outlet port thereby allowing cleaning liquid to be injected through the outlet port, and a float coupled to the piston and configured for displacement thereof to the suction position in response to a rising water level in the toilet tank.

A disinfection system for a toilet includes a toilet tank, a drain opening at a bottom of the toilet tank, at least one disinfection channel extending from the drain opening of the toilet tank to a pedestal for the toilet, and a valve system in the toilet tank, the valve system configured to empty the toilet tank through the drain opening to below a predetermined level.

An electro-chlorinating device includes a housing and a pair of electrodes. The housing comprises a reservoir; an inlet port fluidly coupled to the reservoir; and a discharge device fluidly coupled to the reservoir. The discharge device is configured to be fluidly coupled to a plumbing product. The discharge device is configured to release a fluid from the reservoir into the plumbing product in response to a movement of water through the plumbing product. The pair of electrodes is coupled to the housing such that at least a portion of each electrode of the pair of electrodes is disposed within the reservoir.

A WC device with a WC body and a flushing water supply device for supplying flush water to the toilet body. The flush water supply device is provided with a water connection for drinking water for use as flush water. The WC body has a bowl-shaped WC body section and a subsequent odor trap. The bowl-shaped WC body section has a porous inner surface which is connected to a device for supplying cleaning fluid for keeping the porous inner surface clean. The flushing water supply device is provided with at least one back-suction safety device, which prevents back-suction of cleaning liquid from the porous inner surface to the water connection. Thus, the WC device completely or at least largely prevents excrement or dirt residues from adhering to the inner surface of the WC body, and the back-suction safety device provides hygienically flawless protection on the drinking water side.

A liquid dispenser is provided including a housing having an inlet port connectable to a liquid container, an outlet port configured to be in fluid communication with toilet tank, and a piston slidably mounted in the housing and selectively displaceable between a suction position in which the piston is displaced away from the inlet port thereby allowing suction of cleaning liquid through the inlet port and an injection position in which the piston is urged towards the outlet port thereby allowing cleaning liquid to be injected through the outlet port, and a float coupled to the piston and configured for displacement thereof to the suction position in response to a rising water level in the toilet tank.

TOILET MAID is a product to keep toilet bowls clean with a liquid cleaner. It is composed of two major parts; a reservoir capable of being refilled and a float lever to control output. System is installed in toilet tank with 2 hook hangers. The float system opens the hole in the reservoir when stool is flushed and water drops allowing float to drop. When the water rises the float rises and shuts off hole in reservoir. This constant use keeps the toilet clean and avoids cleaning with brush and severe chemicals.

A self-cleaning toilet assembly, configured to operate in a flush mode to perform a flush cycle to clear a toilet bowl of bowl contents, and to operate in an independent on-demand cleaning mode to perform a clean cycle to clean the bowl. The toilet assembly comprises a clean cycle actuator and a chamber housing coupled to a lower tank lid. The cleaning agent chamber may be positioned in the housing in an inserted position during operation of the toilet, and may be positioned at least partially extended out of the housing in order to refill the chamber with cleaning agent.
