By passing clean water through the activated carbon unit 22, molecules contained in the clean water are removed in trace amounts. For example, it is said that activated carbon 22a is effective for removing odors, and inhibiting activated carbon is effective for removing viruses.

As an example, the membrane unit 24 is mainly composed of what is called an ion exchange membrane 24a, and can adsorb ions contained in the tap water in small amounts. This membrane unit 24 is said to be suitable for removing bacteria.

Although the clean water that has passed through the filter section 2 is not subjected to distillation or heat treatment, it is possible to discharge water having a quality substantially similar to that of distilled water.

However, at present, it is not possible to completely eliminate the possibility of invasion of foreign matter such as viruses that invade bacteria from the ejection port 30 provided in the main body 10 .

As shown in FIGS. 3 and 6, the ultraviolet light irradiation unit 14 is for irradiating ultraviolet light all over the tap water that has flowed out to the vicinity of the discharge port 30 through the filter unit 2 . The ultraviolet light irradiation unit 14 is mainly composed of a light-emitting diode capable of emitting ultraviolet light, in other words, for example, a UV-LED 14a. In the present embodiment, light is emitted in response to power supplied from the main body 10 side of the ejection device 1.

The proximal side support portion 18d has a space through which clean water that has passed through the filter portion 2 can pass. In addition, the tip side support portion 18 e provides a space that allows ultraviolet light to be emitted from the ultraviolet light irradiation portion 14 toward the running water diffusion portion 18 .

A shaft member 18a1 is arranged along the axis of the diffusion body 18a. The shaft member 18a1 is supported by a plurality of shaft support members 18a2 at positions on the proximal side and the distal side of the diffusing section main body 18a. The diffusing section main body 18a is rotatably supported by a proximal support section 18d on the proximal side of the shaft member 18a1, and is rotatably supported by a distal support section 18e on the distal side of the shaft member 18a. In addition, a plurality of discharge holes 18a3 are provided on the side surface of the diffusing portion main body 18a.

Further, a diffusion member 18c1 is arranged on the inner surface of the diffusion tube 18c. The diffusion member 18c1 is provided with, for example, a large number of projections processed into a substantially quadrangular pyramid shape. The surface of the protrusion is provided in a mirror-finished (reflector) shape. The diffusion member 18c1 is irradiated with the ultraviolet light from the ultraviolet light irradiation unit 14, so that the ultraviolet light can be diffusely reflected inside the diffusion tube 18c.

Further, the diffusing portion main body 18a can be rotated by applying the water pressure of running water to the diffusing blades 18b provided on the outer surface of the diffusing portion main body 18a.

Furthermore, the surface of the running water diffusing portion 18 is processed into a mirror surface, thereby forming a rotating reflecting surface 16 a capable of reflecting the ultraviolet light from the ultraviolet light irradiation portion 14 . That is, in the present embodiment, the running water diffusing portion 18 and the ultraviolet light reflecting portion 16 are integrally provided. Specifically, the inner surface 10a of the main body 10 and the rotary reflecting surface 16a constitute the ultraviolet light reflecting portion 16 according to the present invention.

In addition, the flowing water diffusing portion 18 has a plurality of diffusing blades 18b spirally arranged around the axis, so that the diffusing main portion 18a rotates, passes through the filter portion 2, and spreads on the inner surface of the diffusing main portion 18a. and the water located on the outer surface are irradiated with ultraviolet light in a state of being moderately agitated. As a result, it is possible to effectively sterilize germs and viruses that may flow in from the ejection port 30 . It should be noted that the water discharged from the discharge port 30 by the action of the filter portion 2 is of extremely high quality.

Here, specifically, for example, activated carbon 22a is effective against odors, suppressive activated carbon is effective against viruses, and membrane/UV, that is, ultraviolet light is effective against bacteria. That is, the present invention effectively combines activated carbon 22a, suppressing activated carbon, membrane unit 24, and UV, i.e., ultraviolet light irradiation unit 14, to provide a so-called "water faucet with a built-in composite filter media filter, equipped with a UV rotary diffusion device".

That is, the ultraviolet light irradiated from the tip of the main body 10 is guided substantially spirally to the discharge port 30 between the running water diffusing portion 18 and the inner surface of the main body 10. The light is diffusely reflected between the rotary reflecting surface 16a of 16 and is irradiated all over. The clean water guided into the diffusion cylinder 18c is irradiated with ultraviolet light diffusely reflected by the diffusion member 18c1, which is a mirror-finished quadrangular pyramid-shaped projection formed on the inner surface of the diffusion cylinder 18c. Then, the clean water guided into the diffusion tube 18c and irradiated with the ultraviolet light is discharged from the discharge hole 18a3 formed in the diffusion portion main body 18a. As a result, the water in the vicinity of the ejection port 30 is ejected from the ejection port 30 in a state of being effectively sterilized by the irradiation of the ultraviolet light.

In this way, in the present embodiment, the water flowing out from the faucet at the terminal through the water supply pipe is filtered by the discharge device 1 by the UV device in addition to the unit equipped with the filter media. The ultraviolet light irradiation unit 14, which is a UV device, can suppress target viruses and pathogenic microorganisms.
