The air pump 20 and the cover body may be fixedly connected or movably connected.

In use, the suction pump 20 is used to evacuate the device in which the lid is used.

The sealing and holding state means that the sealing member M is located in the pressure relief hole 25 and is in sealing engagement with the pressure relief hole 25. The pressure release holding state means that the sealing member M is separated from the pressure release hole 25. The sealing member M is not limited to a specific structure as long as it can seal and release the pressure from the pressure release hole 25.

The sealing member M may be made of a flexible material, such as rubber, silicone, etc., to seal the pressure relief hole 25. Of course, the sealing member M may also include a central member 12 made of rigid material, such as metal, rigid plastic, etc., and when rigid material is used, an O-ring 13 or the like is provided outside the central member 12 to ensure sufficient sealing performance.

When the sealing member M is in the seal holding state with respect to the pressure release hole 25, the user operates the state change control member 2, the sealing member M is separated from the pressure release hole 25, and this separated state is ensured, at which time the suction pump 20 does not operate.

The state maintaining mechanism completes the switching between the sealing maintaining state and the pressure relief maintaining state through the two processes.

It should be noted that the same orientation does not mean that the first inclined surface 28, the third inclined surface 29 and the second inclined surface 11 are inclined at the same angle, but means that they are inclined at the same tendency, and as shown in the drawing, they are all inclined toward the lower left, and of course, in other embodiments, they may be inclined toward the lower right.
