In some examples of the invention, as shown in fig. 10 and 14, the connecting buckle 12 defines a slot 121 with a side opening, as shown in fig. 10, the second mounting lug 22 can be received in the slot 121, so as to limit the vacuum pump 20 in the up-and-down direction by the cooperation of the slot 121 and the positioning column 11.

Further, the insertion groove 121 may receive the second mounting lug 22 with the wall surface of the insertion groove 121 facing inward (as shown in fig. 10, the top wall of the insertion groove 121 is recessed upward), thereby forming a catching groove 122 that receives the shock-absorbing member 30.

The third protrusion 123 is formed on a groove wall of the slot 122 and/or a groove wall of the slot 121, for example, the third protrusion 123 may be formed on a bottom wall of the slot 121 (i.e., an upper surface of the inner lid 10), a side wall of the slot 121, or a wall surface of the slot 122 facing the inner lid 10, so as to reduce a contact area between the damping component 30 and the connection buckle 12, further reduce heat of the inner lid 10 from being transferred to the vacuum pump 20 through the connection buckle 12, perform a heat insulation function, and reduce vibration of the vacuum pump 20 from being transferred to the inner lid 10 through the connection buckle 12, thereby achieving a noise reduction effect.

As shown in fig. 13, in order to prevent the second mounting lug 22 from directly contacting the connection buckle 12, and thus to prevent the vibration generated when the vacuum pump 20 operates from being directly transmitted to the inner lid 10 through the second mounting lug 22 and the connection buckle 12, and thus to prevent the vibration of the lid assembly from being increased, the thickness b of the second mounting lug 22 is smaller than the dimension a of the insertion groove 121 in the thickness direction of the second mounting lug 22, and the width L of the second mounting lug 22 is smaller than the dimension X of the insertion groove 121 in the width direction of the second mounting lug 22, so that the vacuum pump 20 is effectively prevented from directly contacting the inner lid 10.
