It is actually needed and is configured, for example, may be configured as satisfaction and be not result in that first pressure switch 204 enters from faucet one glass of water of releasing
Enter closed action, thus preventing pump 203 repeatedly starting and stopping.Because the pressurized tank of setting is when opening faucet 202, can be first
Water in pressurized tank is released, prevents hydraulic pressure from strongly reducing, directly initiate pump 203；In addition when closing faucet 202, will not
Impulse high voltage at once, closes pump 203, thus playing cushioning effect to pump 203, is conducive to extending the service life of pump 203.
Further, based on any of the above-described embodiment, in the present embodiment, water outlet module 20 is also included for the described 3rd
The active carbon filter 211 that water in connecting tube 207 is filtered, described active carbon filter 211 is located at described faucet 202
And first pressure switch 204 between.
In the present embodiment, due to also setting up an active carbon filter 211 before current depotition cock 202, water was carried out
Filter, thus further increase water quality.
Further, based on any of the above-described embodiment, in the present embodiment, above-mentioned water receiver 201 is can be according to water storage volume production
The containment structures of raw height change；The top of described water receiver 201 is provided with opens for the fine motion detecting described water receiver 201 height
