| titleOfInvention | Projection screen structure |
| abstract | The invention provides a projection screen structure, comprising a projection screen and an eraser. The projection screen includes a projection writing layer with a coarse face; an absorption layer absorbs to the projection writing layer. The eraser contains a plate housing having a reception space, a connection member at the bottom, and at least a water-spraying hole. The plate housing possesses an operation hole and an inlet hole that are connected to the reception space; a liquid-injecting mechanism installed in the reception space and connected to and between the operation hole and spray hole includes a spray button on the operation hole and a spray member on the spray hole; an erasing body contains a connection member that is linked to connection member of the plate housing. By this way, the projection screen can perform a projection without reflective light spots and have a simple and convenient writing/erasing function by means of the eraser; thus having superior economic efficacy. |
