Wherein the method comprises the following steps: thread groove (1), bowl cover (2), sliding tray (3), pull ring (4), fixing base (5), outer piston (6), buffer spring (7), connecting rod (8), inner piston (9), cup (10), air vent (11), gas collecting tank (12), release gasbag (13).

The specific implementation mode is as follows:

example 1

The invention discloses an anti-suction cup with a cup cover, which is realized by the following steps: the invention relates to a cup cover suction-proof teacup which comprises a threaded groove (1), a cup cover (2), a sliding groove (3), a pull ring (4), a fixed seat (5), an outer piston (6), a buffer spring (7), a connecting rod (8), an inner piston (9), a cup body (10), a vent hole (11), a gas collecting groove (12) and a pressure relief air bag (13), wherein the cup body (10) is arranged at the bottom of the cup cover (2) in a threaded manner through the threaded groove (1), the fixed seat (5) is arranged at the edge of the top of the cup cover (2), the fixed seat (5) is gradually arched upwards from two ends to the middle part, the pull ring (4) is arranged in the middle part of the fixed seat (5), the sliding groove (3) is formed at the top of the cup cover (2), the cross section of the sliding groove (3) is circular, the outer piston (6) is arranged at the top end of the sliding groove (3), the edge of the outer piston (, the other end of the connecting rod (8) penetrates through the bottom of the sliding groove (3) and extends out of the sliding groove (3), a buffer spring (7) is sleeved on the connecting rod (8) and is arranged in the sliding groove (3), an inner piston (9) is arranged at the other end of the connecting rod (8), the diameter of the inner piston (9) is larger than that of the sliding groove (3), and a gap is formed between the inner piston (9) and the sliding groove (3);

during the use, after the hot water cooling in the cup, the inside atmospheric pressure of cup and outside atmospheric pressure are unbalanced, and outer piston (6) are influenced by external atmospheric pressure and are overcome buffer spring (7) stress and move downwards to this makes interior piston (9) that the bottom is connected through connecting rod (8) move down, reduces the volume that occupies of the inside air of cup with this change mutually, thereby reaches the effect of balanced cup inside and outside atmospheric pressure difference, prevents that bowl cover (2) from being held and can't open.

Example 2

The difference between this example and example 1 is: the cup cover (2) is provided with a group of vent holes (11), the vent holes (11) are arranged around the circle center of the cup cover (2) in a fan-shaped and equidistant manner, the bottom of each vent hole (11) is provided with a gas collecting tank (12), the vent holes (11) are communicated with the gas collecting tanks (12), one end of each gas collecting tank (12) is a horizontal plane, the other end of each gas collecting tank (12) penetrates through the bottom of the cup cover (2) and extends into the cup body (10), the section of the other end of each gas collecting tank (12) is a downward convex arc surface, the bottom of each gas collecting tank (12) is provided with a pressure relief air bag (13), and a;

when in use, after the cup body (10) and the cup cover (2) are screwed down, the structure of the inner piston (6) and the outer piston (6) is changed into the pressure relief air bag (13) which can be expanded, when the air pressure difference is generated between the inside and the outside of the cup body (10), the outside air is pressed into the air collecting groove (12) through the vent hole (11), so that the pressure relief air bag (13) is correspondingly expanded towards the inside of the cup body (10), the occupied volume of the air in the cup body (10) is reduced, and the air pressure difference between the inside and the outside of the cup is balanced;

the design that the buffer spring (7) is sleeved on the connecting rod (8) can increase the pressure when the outer piston (6) moves downwards when the connecting rod (8) moves up and down, so that the moving speed is reduced, the impact force on the sliding groove (3) is reduced, and the service life of the cup is prolonged;

the design that a gap exists between the inner piston (9) and the sliding groove (3) can increase the moving distance of the connecting rod (8), increase the using space of the inner piston (9) and enhance the effect of balancing the air pressure difference between the inside and the outside of the cup;

the design that the pressure relief air bag (13) is provided with the heat insulation layer can enhance the sealing performance of the teacup and avoid that hot air in the teacup is lost too fast to influence the heat insulation effect of the teacup;

the cup achieves the aim of balancing the cup by adjusting the air pressure inside and outside the cup without manual adjustment.
