The invention is a backlight structure improvement of the control panel of the main body of an electric sucking milk device.It includes a control panel,A light shielding coating and at least one light source,The control panel has a light transmitting housing.And the shading coating is light-proof material.And the shading coating is arranged on the transparent shell.And the shading coating has at least one preset exposed pattern.And the at least one light source is arranged on the side of the light transmitting shell far away from the light shielding coating.Accordingly,The light produced by the at least one light source,It will penetrate through the light transmitting shell and be emitted only through the at least one preset exposed pattern through the blocking of the light shielding coating.Thus, the shape of the at least one preset exposed pattern can be clearly displayed.When the at least one preset exposed pattern is marked as a different symbol,So that nursing mothers can clearly read the symbols.In order to facilitate the operation of the nursing mother in the control panel and control the operation of the electric sucking device.本創作為一種電動吸乳器本體控制面板背光結構改良,其包含一控制面板、一遮光塗層與至少一光源,其中該控制面板具有一透光殼體,而該遮光塗層為不透光材質,且該遮光塗層設置於該透光殼體上,並該遮光塗層具有至少一預設裸露圖案,又該至少一光源設置於該透光殼體遠離該遮光塗層的一側,據此,該至少一光源產生的光線,會穿透該透光殼體經由該遮光塗層的阻擋而僅經由該至少一預設裸露圖案處射出,因而可以清楚顯示該至少一預設裸露圖案的外形,當該至少一預設裸露圖案作為不同的符號標示時,即可讓哺乳媽媽可以清楚判讀符號標示,以方便哺乳媽媽於該控制面板進行操作而控制電動吸乳器的作動。
