A sealing structure of a drinking water tank. The water tank has a mouth covered with a cap. The cap has a hollow guide recessed from a center thereof, and a sealing cover receiving the hollow guide therein. The hollow guide defines an opening for water contained in the water tank to flow through, while the sealing cover has a bottom wall and sidewall extending perpendicularly from the bottom wall to seal the opening. The sidewall further has a first latching structure at the edge of the sidewall, such that the sealing cover is in friction contact with the hollow guide to provide a sealing effect. The hollow guide also has a second latching structure formed at an edge thereof to be latched with the first latching structure.
