Multipurpose vacuum suction device suction port device and optimal design method

The invention discloses a multipurpose vacuum suction device suction port device and an optimal design method, and relates to the technical field of vacuum suction devices. The problems that an existing vacuum suction device is single in function and low in reliability are solved. According to the technical scheme, the multipurpose vacuum suction device suction port device is characterized by comprising a suction device body and a quasi-shape sealing ring, wherein the suction device body is coaxially provided with a conical suction port, a plane suction port and a spherical suction port, and the diameters of the conical suction port, the plane suction port and the spherical suction port are sequentially increased; and the suction device body is a hard body, the quasi-shape sealing ring is a soft body, and the quasi-shape sealing ring is connected with the suction device body in a sleeving manner. By means of the multipurpose vacuum suction device suction port device and the optimal design method, the suction
