Magnetic suction cup with spherical cup lid

1. 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 ).

2. The magnetic suction cup with the spherical cup lid according to claim 1 , wherein a through hole ( 8 ) is arranged in a center of the stop plate ( 4 ); a lower end of the water stop part ( 6 ) is provided with a connecting rod ( 9 ); the connecting rod ( 9 ) is arranged in the through hole ( 8 ) in a penetrating manner; a lower end of the connecting rod ( 9 ) is provided with a silica gel sleeve ( 10 ); the water stop part ( 6 ) is located above the stop plate ( 4 ); the silica gel sleeve ( 10 ) is located below the stop plate ( 4 ); and the water stop part ( 6 ) and the silica gel sleeve ( 10 ) are both larger than the through hole ( 8 ).

3. The magnetic suction cup with the spherical cup lid according to claim 2 , wherein an upper end of the water stop part ( 6 ) is provided with a silica gel layer ( 11 ); and when the water stop part ( 6 ) moves up, the silica gel layer ( 11 ) resists against the rim ( 3 ).

4. The magnetic suction cup with the spherical cup lid according to claim 1 , wherein the cup body ( 1 ) is provided with a magnetic suction part ( 12 ) for placing the spherical cup lid ( 2 ); and the spherical cup lid ( 2 ) is sucked on a surface of the cup through the magnetic suction part ( 12 ).

5. The magnetic suction cup with the spherical cup lid according to claim 2 , wherein the cup body ( 1 ) is provided with a magnetic suction part ( 12 ) for placing the spherical cup lid ( 2 ); and the spherical cup lid ( 2 ) is sucked on a surface of the cup through the magnetic suction part ( 12 ).

6. The magnetic suction cup with the spherical cup lid according to claim 3 , wherein the cup body ( 1 ) is provided with a magnetic suction part ( 12 ) for placing the spherical cup lid ( 2 ); and the spherical cup lid ( 2 ) is sucked on a surface of the cup through the magnetic suction part ( 12 ).

7. The magnetic suction cup with the spherical cup lid according to claim 4 , wherein a surface of the cup body ( 1 ) is sunken downwards to form a placement slot ( 13 ); the placement slot ( 13 ) is arranged on an outer side of the magnetic suction part ( 12 ); and the placement slot ( 13 ) is an arc shape matched with the spherical cup lid ( 2 ).
