[0042] figure 1 is a perspective view of the water faucet device 2 according to the first embodiment. The faucet assembly 2 is installed on a kitchen sink (not shown in the figure). exist figure 1 The part that is not visually identifiable, that is, the part located inside the kitchen sink, is omitted in . In addition to the kitchen, the faucet device 2 can also be installed in, for example, washrooms and bathrooms.

[0043] The faucet assembly 2 comprises a body part 4 , a lever handle 6 and a drain head 8 . The water faucet device 2 is a so-called single-lever type water faucet. The temperature of the discharged water can be adjusted by pivoting the lever handle 6 left and right. The amount of discharged water can be adjusted by pivoting the lever handle 6 up and down. A valve mechanism capable of adjusting the temperature and amount of discharged water is housed inside the body portion 4 . Such valve mechanisms are known.

[0044] Although not shown in the drawings,...

Abstract

Provided is a water purification filter element which prevents erroneous recognition of drainage and is excellent in reliability. The drain head 8 includes: a regulating member RG1, which can be switched between the first state J1 and the second state J2, so that in the first state J1, the switching mechanism is prevented from switching from raw water discharge to purified water discharge, and in the second state Under J2, the switching mechanism is allowed to switch from raw water discharge to purified water discharge; the adjustment part DR1 is released, which makes the adjustment member RG1 switch from the first state J1 to the second state J2; the water purification filter element PC1, which includes an impermeable front closed outer surface 196: The receiving part of the water purification filter element. The front closed outer surface 196 faces the raw water flow path WG. The regulating member RG1 is provided in the purified water flow path WJ.

Description

technical field [0001] The invention relates to a drain head with water purification function, a water purification filter element and a faucet device. Background technique [0002] A drain head is known which includes a water purification cartridge and has a water purification function. JP3454756B2 discloses a shower head that has a water purification function and can switch between a raw water flow path that does not pass through a water purification filter element and a purified water flow path that passes through a water purification filter element. [0003] This type of drain head or a faucet device equipped with the same includes an operating portion capable of switching between raw water discharge and purified water discharge. Examples of manipulative parts include buttons, levers, and dials. Some faucet devices may further include a display portion showing whether raw water discharge or purified water discharge is selected. [0004] The user can recognize whether ...
