| Zusammenfassung: | The utility model discloses a magnetic type induction uncovering vacuum cup which comprises a cup body, one end or two ends of the cup body are provided with a cup opening, the cup opening is provided with a ferromanganese connector, the ferromanganese connector is of a circular ring structure, and the end portion of the cup opening is higher than the ferromanganese connector. The magnetic cup cover is used for generating magnetic attraction force with the annular magnet on the connecting part and sealing the cup opening; the magnetic cup cover is simple in structure and convenient to operate, the electromagnet of the magnetic cup cover is close to the ferromanganese connector on the cup opening, magnetic attraction force is generated to attract the electromagnet and the ferromanganese connector, and the upper end of the cup opening abuts against the silica gel rubber ring. When the inductive switch is pressed down, the magnetic attraction force on the electromagnet disappears, and at the moment, the electrom |
