<p>Pumping device designed to supply pre-measured amounts of liquid, tunable prior to or during use. The device is built onto a container filled with liquid detergent. The container is hanged upside down in a lavatory basin. The system is passive between flushes. The device comprises a reservoir and a siphon. The liquid is accumulated in the reservoir, which is able to change its own capacity by rotating the device in the 'open' or 'close' direction. The short section of the tube is dipped into the detergent reservoir providing the siphon. As the water is flushed from the basin, the water level is lowered and the detergent from the reservoir is pumped into the basin by the siphon effect.</p> |
