Patent ID: 8623179

Claim:
A seawater desalinization device, comprising: a container portion defining a receiving chamber for storing seawater, a slot, and a through hole communicating with the receiving chamber, a heat absorption layer coated on an inner wall of the receiving chamber; a guiding pipe fixed on the container portion to communicating with the slot; a plug detachably inserted into the guiding pipe; a heat conduction cover covering on the container portion and sealing the receiving chamber and the slot, the heat conduction cover made of transparent toughened glass comprising a cover portion which is a convex lens for focusing solar energy and the heat conduction cover making fresh water evaporated from the seawater to drop into the slot, the heat conduction cover defining a plurality of guiding slots facing the container portion; a switch assembled in the container portion to control the through hole to open or close upon a seawater level which stored in the container portion; and a connecting pipe connected to the through hole and a seawater source; wherein the plurality of guiding slots take a center of the heat conduction cover as a radiation center and are defined in the heat conduction cover; a bottom wall of the slot is an inclined plane and a hole is defined at the lowest portion of the slot, the cross-sectional view of the slot is semi-circular; the heat absorption layer absorbs the solar energy to increase the temperature of the seawater, and the fresh water is evaporated from the seawater and gathered on the cover portion; the fresh water is stored in the plurality of guiding slots and automatically drops into the slot due to gravity and is stored in the guiding pipe.
