Claims

[Scope of utility model registration request]

a base portion formed with an inflow channel connected to the water supply pipe via a water supply on-off valve, and a drainage channel to which an on-off valve having a valve body biased in a closing direction is attached; The main body is composed of an outer cylinder part connected to the base part, a lid part connected to the outer cylinder part, and a filter agent is filled in the upper half of the internal space. is,
a filtration tube having a main raw water introduction hole on the top surface and an outflow hole connected to the drainage channel on the bottom surface, and slidably engaged with the inner circumferential surface of the lid part;
A cap-shaped piston biased in a direction against water pressure, a pressure-accumulating water storage chamber formed inside the cap-shaped piston, and connected to the piston, whose reciprocating motion allows the main raw water introduction hole of the filtration tube to be opened. A main valve body to be opened and closed, an inner cylinder part disposed between the outer peripheral surface of the filtration cylinder and the inner peripheral surfaces of the base part and the outer cylinder part, and partitioned by the inner cylinder part. two inner and outer annular channels, and these two
a conduction hole that communicates two annular channels near the outlet of the inflow channel; an auxiliary raw water introduction hole that communicates the inner annular channel with the lower half of the filtration cylinder; and an opening/closing valve for water supply of the water pipe. A water purifier comprising an auxiliary valve body that closes and opens the communication hole using water pressure in response to an operation.
