The formed pure water pressurizes the filter chamber 131, i.e., increases the pressure in the filter chamber 131, during the movement of the piston 14 in the direction to approach the filter chamber 131, thereby accelerating the discharge of the pure water in the filter chamber 131 and increasing the flow rate. And the piston 14 for pressurizing is directly arranged in the cavity formed by the filter shell 13, and the influence on the whole structure size is small.
It should be noted that, during the process that the piston 14 moves away from the filter chamber 131 under the action of the telescopic power member 15, the filter chamber 131 is not pressurized at this time, and at this time, mainly under the action of the external water pressure, the water in the filter bottle 11 passes through the filter housing 13 and the filter membrane 12 to be filtered, so as to form pure water. The formed pure water can continuously flow outwards for users to use. When the piston 14 moves toward the filter chamber 131, the filter chamber 131 is pressurized, and pure water flows out faster and at a higher flow rate.
