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