Liquid storage system, liquid container, and liquid lead-out control method

1. A liquid storage system comprising:

a liquid container having a plurality of through holes of a nano-size from which volatile liquid contained in the liquid container is led outside by capillary action, and photocatalytic films provided on surfaces of the through holes, the photocatalytic films being hydrophilic during light irradiation;

an irradiation unit configured to irradiate the photocatalytic films with light; and

a control unit configured to control the irradiation unit in accordance with an amount of the volatile liquid to be led outside.

2. A liquid container comprising:

an outlet from which liquid contained in the liquid container is led outside by capillary action; and

a photocatalytic film provided on a surface of the outlet, the photocatalytic film being hydrophilic during light irradiation,

wherein the liquid contained in the liquid container is led outside in response to light irradiation of the photocatalytic film.

3. The liquid container according to claim 2 , further comprising:

a liquid container body having an open portion and containing the liquid; and

a cover configured to cover the open portion of the liquid container body, wherein the outlet is provided in the cover.

4. The liquid container according to claim 2 , wherein the outlet includes a plurality of through holes of a nano-size.

5. The liquid container according to claim 2 , wherein the liquid is a volatile liquid.

6. A liquid storage system comprising:

a liquid container including an outlet from which liquid contained in the liquid container is led outside by capillary action, and a photocatalytic film provided on a surface of the outlet, the photocatalytic film being hydrophilic during light irradiation; and

an irradiation unit configured to irradiate the photocatalytic film with light,

wherein the liquid contained in the liquid container is led outside in response to light irradiation of the photocatalytic film.

7. A liquid lead-out control method comprising:

suppressing irradiation of a photocatalytic film with light so as to suppress lead-out of liquid contained in a liquid container by capillary action at an outlet,

wherein the liquid container includes the outlet and the photocatalytic film, the outlet is provided in a manner such that the liquid is led outside therefrom, and the photocatalytic film is provided on a surface of the outlet in a manner such as to be hydrophobic when the irradiation is suppressed.

8. The liquid lead-out control method according to claim 7 , further comprising:

irradiating the photocatalytic film with the light so as to promote lead-out of the liquid by capillary action at the outlet.
