[0002] At present, the market of small and medium-sized reverse osmosis water purifier is broad, but due to the small size, the connection between the water outlet of the water storage device of the water purifier and the water outlet pipe is prone to air blockage, that is, air is left in the connection, which causes the purified water to be unable to be discharged. This situation usually occurs in atmospheric water tanks.

[0003] In the prior art, a pressure barrel can be used as a water storage device for small and medium-sized water purifiers. The internal pressure of the pressure barrel can squeeze out the air in the connection, so that the purified water can be smoothly discharged even if the flow is not large. However, since internal pressure is needed, the pressure barrel is a closed space, and the purified water therein is prone to breed a large number of bacteria, which tastes bad. Although some manufacturers install germicidal lamps (such as ultraviolet lamps, LED sterilizers, etc.) at the water outlet end of the pressure barrel, the germicidal lamps need a period of time to start, so there will always be a situation that the bacterial content of the first few cups of water exceeds the standard when taking water.
