The present disclosure provides a descaling apparatus of an electronic toilet bidet, the descaling apparatus comprising: a descaling liquid storage tank comprising a descaling liquid chamber configured to house descaling liquid, wherein a pressure element is disposed and movable in the descaling liquid chamber, wherein the descaling liquid chamber comprises a descaling liquid outlet, wherein the descaling liquid storage tank further comprises a main body liquid outlet fixedly connected to and in communication with a bidet liquid inlet of the electronic toilet bidet, and wherein the main body liquid outlet is configured to be controlled to connect or disconnect the descaling liquid outlet. The descaling apparatus according to the present disclosure may supply the descaling liquid automatically and continuously to the internal pipes of the electronic toilet bidet for several times after the descaling liquid is added at one time.

A water conserving toilet disinfectant dispenser uniformly dispenses a solid disinfecting composition in the water that is flushed by the toilet, which then flows across the toilet bowl. The disinfectant dispenser includes a perforated container that retains a solid disinfecting composition. The disinfectant dispenser also includes a coupling conduit having a top end that mates with, and receives water from, a refill tube integral in toilet tank. The coupling conduit also has a bottom end that discharges the water at an angle into the overflow tube, so as to minimize splashing and water waste over the rim. The dispenser further includes a tension leg that clips to the top rim of the overflow tube to retain the dispenser in an upright position. The tension leg is elongated and has a grip layer at the inner face that maintains stability for the container, even under turbulence from water entering overflow tube.

An automatic toilet cleaning apparatus that discharges cleaning fluid into the water of a tank of a toilet during each flush. The apparatus includes a container having an extendable bladder therein that successively fills with water during each flush thereby successively pushing out a small amount of cleaning fluid into the water of the toilet tank to clean the bowl of the toilet.

A liquid dosing apparatus for dispensing a liquid from a container into a liquid stream of a shower, toilet, or tap includes an adapter, a dosing mechanism, a damping control system, and a dispensing outlet. The adapter is arranged to detachable receive the container. The dosing mechanism includes a dosing chamber and a movable member. The dosing mechanism is arranged to draw a set volume of the liquid into the dosing chamber on activation by moving the moveable member in a first direction. The damping control system is arranged to control a dispensing rate of the set volume of the liquid by controlling return speed of the moveable member. The damping control system is arranged to allow and control adjustment of the dispensing rate. The dispensing outlet is arranged to dispense the liquid into the water stream at the controlled dispensing rate.

A water supply system for aircraft that is mounted on an aircraft to supply water to a plurality of water supply outlets in the aircraft. The water supply system for aircraft includes a tank for storing water, a water supply pipe, and an ultraviolet sterilization device. The water supply pipe extends from the tank, branches and is connected to each of the plurality of water supply outlets, and supplies water from the tank to the plurality of water supply outlets. The ultraviolet sterilization device is provided on the water supply pipe close to at least the water supply outlet for drinking water, includes a light-emitting diode emitting ultraviolet light, and sterilizes water supplied to the water supply outlet by irradiating the water with ultraviolet light from the light-emitting diode.

A restroom system includes a sanitation station configured for hand washing and a waste station configured to receive a waste material from a user. A suds mixture is flowable through the sanitation station and the waste station and is configured for hand washing and to receive the waste material. The suds mixture includes a fluid layer and a suds layer positionable between the fluid layer and the user so that when the suds mixture receives the waste material the suds layer changes from an original shape to absorb energy and allow passage of the waste material through the suds layer into the fluid layer and then returns toward the original shape to form a protective barrier between the user and the waste material in the fluid layer.
