A mechanical hand held door opener device, light in weight and operable in any orientation including being inverted, for generating substantial door-opening force with a minimum effort from a user. The particle includes, for example, an organic phosphorescent material encapsulated in a cross-linked halogen-containing polymeric matrix. A metal plate is formed on an upper surface of the plating layer and filled with a second insulator at a position corresponding to the division area, with an anodized layer formed on a surface of the metal plate. A second optimization is performed. The four wiper units can move to a position enabling wiping unit heads, and a position enabling wiping unit heads. The electronics module is arranged above of the base module, the nozzle module is arranged above the base module, the column module is arranged above the nozzle module and the top module is arranged above the column module.
