<p>A cleaning solution dispenser installed in a water tank 2 includes a container 3 and a tubular flow regulator 4. The container receives cleaning solution therein and is formed with a downwardly opening outlet 31. The flow regulator extends into the outlet of the container and is divided by a partition plate 40 into upper and lower chambers 41, 42. The upper chamber has a closed top end and a surrounding wall formed with at least one radial port 43 opening adjacent to the partition plate. The flow regulator further has first and second tubes 44, 45 which extend upwardly from the partition plate into the upper chamber. The second tube is shorter than the first tube and has a top end which is located at a level higher than that of the port opening. The first and second tubes communicate the upper chamber with the lower chamber. The lower chamber has an open bottom end. The cleaning solution in the container flows through the flow regulator via the port opening, the upper chamber, the second tube and the lower chamber when air pressure in the upper chamber is less than pressure in the container.</p> |
