The following describes the use of the cup lid and the vacuum cup of the present invention with reference to fig. 1 to 11.

After the lid is assembled, the lid is placed on the cup 12 and the lid is tightened to seal the lid to the open end of the cup 12. The pressing knob 5 is rotated to change from the locking state to the unlocking state, at this time, the locking block 41 on the locking ring 4 moves to the position of the sliding groove 313 away from the limit step 312 of the air pump outer cylinder 31, and the air pump inner cylinder 33, the air pump outer cylinder 31 and the first sealing ring 32 move upwards under the elastic force of the spring 34. The first sealing ring 32 is tightly attached to the first convex edge 331 at the bottom of the air pump inner cylinder 33 under the action of the downward friction force of the inner wall of the third cylinder 102 in the upper cover 1, the first sealing ring 32 seals the gap between the first convex edge 331 and the third cylinder 102, and the air in the pumping cavity 100 cannot enter the groove between the first convex edge 331 and the second convex edge 315. During the upward movement of the air pump inner cylinder 33, the volume of the air pumping cavity 100 is increased, because the air in the air pumping cavity 100 is sealed, the pressure in the air pumping cavity 100 is reduced, the pressure in the cup body 12 is greater than the pressure in the air pumping cavity 100, the notch 92 of the waterproof valve 9 is opened, the air in the cup body 12 enters the second cylinder 26 and exerts an upward thrust on the check valve 7, so that a gap is generated between the check valve 7 and the second through hole 24, the air passes through the second through hole 24 through the gap and then enters the air pumping cavity 100 through the air passage between the check valve fixing member 6 and the first through hole 107 until the pressures in the cup body 12 and the air pumping cavity 100 are balanced.

When the spring 34 returns to the natural state, the air pump inner cylinder 33, the air pump outer cylinder 31 and the first sealing ring 32 do not move upwards any more, the pressing knob 5 is pushed downwards to drive the air pump inner cylinder 33, the air pump outer cylinder 31 and the first sealing ring 32 to move downwards, the first sealing ring 32 is tightly attached to the second convex edge 315 at the bottom of the air pump outer cylinder 31 under the action of the upward friction force of the inner wall of the third cylinder 102 in the upper cover 1, the air in the air pumping cavity 100 is communicated with the outside through the gap between the first convex edge 331 and the third cylinder 102 and the vent hole, during the downward movement of the air pump inner cylinder 33, the air pump 31 and the first sealing ring 32, the volume of the air pumping cavity 100 is reduced, the pressure in the air pumping cavity 100 is increased, the check valve 7 blocks the second through hole 24 under the action of atmospheric pressure and self gravity to prevent the air from entering the cup body 12, the air in the air pumping cavity 100 is discharged to the outside through the gap between the first convex edge 331 and, until the suction assembly 3 cannot be pushed down, the spring 34 is in a compressed state. When the pressing knob 5 is released again, the air pump inner cylinder 33, the air pump outer cylinder 31 and the first sealing ring 32 move upwards under the action of the elastic force of the spring 34, the previous step is repeated, the air in the cup body 122 is pumped out, and the circulation is carried out, so that the air in the cup body is gradually emptied.

The utility model discloses a set up detachable upper cover 1 and lower cover 2, the upper end of upper cover 1 is equipped with air exhaust component 3, and 2 bottoms of lower cover are equipped with waterproof valve 9, and bowl cover waterproof performance is good, is equipped with check valve 7 between upper cover 1 and the lower cover 2, and the bowl cover is dismantled easily, conveniently washs bowl cover interior subassembly to simple structure, overall arrangement are compact, easily miniaturization.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should be all included in the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
