Magnetic suction cup with spherical cup lid

A magnetic suction cup with a spherical cup lid, wherein the magnetic suction cup comprises a cup body (1) and the spherical cup lid (2), wherein the spherical cup lid (2) is provided with a metal material capable of being attracted by a magnetic force;

• an upper end of the cup body (1) is provided with an arc-shaped rim (3);
• an inner end of the rim (3) is provided with a stop plate (4);
• a peripheral edge of the stop plate (4) is connected to the cup body (1), and the stop plate (4) is provided with several water passing holes (5);
• a water stop part (6) is arranged between the rim (3) and the stop plate (4);
• the water stop part (6) moves up and down between the rim (3) and the stop plate (4);
• when the water stop part (6) moves up, the water stop part (6) resists against a lower end of the rim (3), and the rim (3) is closed;
• when the water stop part (6) moves down, the water stop part (6) resists against the stop plate (4), and the rim (3) is opened;
• a magnetic suction member (7) is arranged on the water stop part (6);
• when the spherical cup lid (2) is arranged at the rim (3), the magnetic suction member (7) is sucked to the spherical cup lid (2) through a magnetic force, thus driving the water stop part (6) to move up to close the rim (3);
• and when the spherical cup lid (2) is opened, the magnetic suction member (7) loses a suction force and drives the water stop part (6) to be reset to open the rim (3).
