Water filtration and sterilisation device

摘要

The present invention provides a water filtration and sterilization device comprising a container having an inlet conduit and an outlet conduit, a closure valve at said inlet conduit, a filter means upstream of said inlet conduit, a flow prevention means in said outlet conduit and an ultra violet radiation source within said container. The valve is adapted to be opened for a first time period to admit water into the container via the filter means. The ultra violet radiation source is operable for a second time period to sterilize water in said chamber. The first time period is shorter than said second time period. The flow prevention means is operable to deliver sterilized water on demand from the container.

1. A water filtration and sterilisation device, comprising:
a casing comprising a first container and a second container within the casing, the first container and the second container each being configured to contain water therein, the first container comprising a base having a recess, the recess comprising a first outlet conduit in fluid communication between the first container and the second container, the second container having an outlet and a second outlet conduit; a closure valve coupled to said first outlet conduit; a filter upstream of said first outlet conduit; a flow prevention means coupled between said second container outlet and said second outlet conduit; an ultra violet radiation source within said second container; and a controller, wherein the controller is configured to:
open the closure valve for a first time period to admit water into the second container via the filter;operate the ultra violet radiation source for a second time period to sterilise water in the second container; andoperate said flow prevention means to deliver sterilised water on demand from the second container; and wherein said first time period is shorter than said second time period.
