The invention relates to the technical field of electric tools, and provides a sealing structure element which comprises an annular sealing structure, the two end faces of the annular sealing structure are communicated through a through hole, and a groove communicated with the through hole is formed in one end face. The invention further discloses an electric suction cup which comprises a handle, a suction cup component and a vacuum pump assembly, the suction cup component comprises the sealing structural element and a suction cup shell, and the sealing structural element is connected with one end face of the suction cup shell. A second closed negative pressure space is formed by the surface of the sucked object, the through hole and the groove of the sealing structure element and the end face, connected with the suction cup shell, of the sealing structure element. According to the electric suction cup, the through hole and the groove can be ingeniously formed in the sealing structure element, a second closed negative pressure space is formed, the suction force of the suction cup is improved, a product is more compact, the working efficiency is higher, and the reliability of the product is further improved.

    本发明涉及电动工具技术领域,本发明提供的一种密封结构元件,所述密封结构元件包括环形密封结构,所述环形密封结构的两个端面由通孔导通,在一个端面上形成有连通所述通孔的凹槽。本发明还公开了一种电动吸盘,包括手柄和吸盘部件、真空泵组件,所述吸盘部件包括如上述的密封结构元件和吸盘壳体,所述密封结构元件与所述吸盘壳体的一个端面连接。被吸附物体的表面、所述密封结构元件的通孔、凹槽、所述密封结构元件与所述吸盘壳体连接的端面形成第二封闭负压空间。该电动吸盘能够巧妙地在密封结构元件设置有通孔和凹槽,形成第二封闭负压空间,提高吸盘的吸附力,使得产品更加紧凑,工作效率更高,进一步提高产品的可靠性。
