に構成してある液体吐出装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid discharge apparatus for discharging a liquid by sterilizing a liquid with ultraviolet rays, and more particularly, to a liquid supply channel and a faucet provided at a tip end of the liquid supply channel. An ultraviolet germicidal lamp that irradiates ultraviolet rays from above the faucet toward the faucet, and the faucet is provided with an ultraviolet transmitting portion that allows irradiation light from the ultraviolet germicidal lamp to pass through the faucet. By discharging the liquid through an ultraviolet-transparent shower plate provided at the lower part of the faucet, the shower plate is formed by a perforated plate having a large number of small holes. The present invention relates to a liquid discharge device configured to be able to store liquid inside the faucet when liquid discharge is stopped.

がある。It is to be noted that the shower plate is formed of a perforated plate having a large number of small holes so that when the discharge of the liquid is stopped, the liquid can be stored in the faucet. The surface tension of the liquid causes the liquid itself to seal the small holes in the shower plate, so that bacteria floating in the air outside the faucet enter the faucet through the small holes, This is because it is possible to reduce the risk of contamination. However, it is difficult to completely seal the small-diameter hole, and air may enter the faucet from the outside of the faucet through the small-diameter hole. In such a case, the liquid stored inside the faucet will not be able to maintain the surface tension and will be dripped and decrease. A layer of air pockets of air that has penetrated the air may be formed.

する問題がある。However, according to the above-mentioned conventional liquid ejecting apparatus, since the flat ultraviolet transmitting portion is provided on the ceiling surface of the housing-shaped faucet main body, the inner surface of the ceiling surface is also flat. It is. For this reason, as described above, if a layer of air trapped inside the faucet between the liquid that was in contact with the inner surface of the ceiling surface and the liquid that was in contact with the liquid that was in contact with the inner surface of the ceiling surface, the liquid that was in contact with the inner surface of the ceiling surface would be In addition, there is a problem that droplets or the like are likely to remain at corners and the like surrounded by the inner surface of the ceiling surface and the inner surface of the faucet. Then, for example, if the tap water is left for a long time, the droplets remaining on the inner surface of the ceiling surface inside the faucet, i.e., the inner surface of the ultraviolet ray transmitting portion, are left as they are for a long time, so that the sterilizing effect itself by chlorination is lost. Bacteria and the like may be generated or multiplied from the droplets and the like, and the inside of the faucet may be contaminated. Also, on the inner surface of the ultraviolet transmitting portion, scales in which the remaining droplets and the like are dried and dissolved components and the like from the liquid are deposited or adhered,
Irradiation light from the ultraviolet germicidal lamp is blocked by the scale, making it difficult for the light to pass through the faucet, resulting in a problem that sterilization efficiency is reduced.

Can reduce the risk of proliferation,
It is an object of the present invention to provide a liquid ejection device that can prevent the efficiency of a sterilization process from decreasing.

And an ultraviolet germicidal lamp 3 for irradiating ultraviolet light from above the outside of the faucet 2 toward the faucet 2.
An ultraviolet transmitting section 4 is provided to allow irradiation light from the ultraviolet germicidal lamp 3 to pass through the faucet 2, and a liquid is discharged through an ultraviolet transmitting shower plate section 5 provided below the faucet 2. The shower plate portion 5 is formed of a perforated plate having a large number of fine small-diameter holes so that the liquid can be stored inside the faucet 2 when the discharge of the liquid is stopped. In a certain liquid ejection device A,
The ultraviolet transmitting portion 4 is formed in a dome shape whose inner surface is curved upward.

収され易いのである。[Operation] In other words, since the inner surface of the ultraviolet transmitting portion is in the shape of a dome that is curved upward, air enters the faucet and an air reservoir is formed between the inner surface of the ceiling surface and the liquid surface of the liquid. Even when a layer is formed, the liquid can be less likely to remain as droplets or the like on the inner surface of the ultraviolet transmitting portion. That is, the liquid level of the liquid stored in the faucet moves downward from the inner surface of the ceiling inside the faucet, and the droplets and the like attached to the inner surface of the ultraviolet transmitting portion are lowered from near the central top of the inner surface of the ultraviolet transmitting portion. It moves downward along the curved surface of the dome, and is easily absorbed by the liquid layer.

The liquid supplied to the inside of the faucet from the section is once supplied to the vicinity of the central top of the inner surface of the ultraviolet transmitting section. Since the inner surface of the ultraviolet transmitting portion has a dome shape, a liquid flow path is easily formed such that the liquid supplied near the center top is dispersed from the vicinity of the center top to the entire inside of the faucet. For this reason, the liquid supplied to the inside of the faucet does not stay in a certain place for a long period of time from being supplied to the inside of the faucet to being discharged to the outside of the faucet through the shower plate portion. Therefore, the liquid is easily circulated from the upper part to the lower part, so that the whole faucet can be easily supplied with a new liquid as a whole.

Since the new liquid is always easily supplied as a whole, it is possible to reduce the possibility that bacteria and the like may be generated or proliferated and the inside of the faucet may be contaminated by the liquid remaining in a certain place for a long time. It is possible to prevent the sterilization treatment efficiency from being lowered. In addition, the efficiency of the sterilization treatment by the irradiation light inside the faucet can be improved by discharging the air inside the faucet to the outside of the faucet and cleaning the inner surface of the ultraviolet ray transmitting portion by the flow action of the liquid flow path.
