When the pedestrian needs to drink water, the pedestrian faces the outlet of the water outlet faucet pipe (the mouth does not contact the water outlet faucet pipe), the adjusting handle seat is rotated by hand to drive the main valve rod, so that the water inlet on-off valve is adjusted (opened), and the direct drinking water can be drunk after the water outlet faucet pipe sprays water. In the process of drinking water, the sprayed water can not be drunk into the inlet as much as possible, so that the part of the direct drinking water which is sprayed out from the water outlet faucet pipe and is not drunk falls into the counter basin and is discharged into a sewer through the drainage pipeline.
The in-process of sewer is gone into to the row that falls into the counter basin, can be through outlet, first drain pipe, case apical pore, filter box inside, bottom of the case hole and second drain pipe, when inside through the filter box, impurity, the rubbish of aquatic can stay in the filter screen pocket, when the filter screen pocket needs clearance, directly open the access door, lift the joint sealing screw off, then can take out side seal boxboard and filter screen pocket and handle, handle the completion back, the dress back side seal boxboard and filter screen pocket can.
In the present case, the water filter need not be absolutely limited, as long as the condition is satisfied: after passing through the water inlet filter, the water at the tap water source reaches the direct drinking water standard (various conventional pure water filter elements in the prior art can meet the conditions, such as PPF cotton/PP cotton, activated carbon and pure water filter elements of a reverse osmosis membrane three-stage filtration type, and PP cotton, honeycomb particle activated carbon, reverse osmosis membranes and pure water filter elements of a high-precision compressed activated carbon four-stage filtration type), and the filter elements are required to be replaced regularly.
