[0020] Furthermore, a silicone gasket is provided on the inner wall of the air extraction hole.

[0021] The beneficial effect of adopting the above further solution is that the silicone gasket is more closely fitted to the extraction end of the manual air pump, thereby enhancing the air tightness between the manual air pump and the air extraction hole.

[0022] Furthermore, the outer side of the sealing plug is provided with anti-slip grooves.

[0023] The beneficial effect of adopting the above further scheme is that the design of the anti-slip pattern increases the friction between the sealing plug and the hand. The increased friction enables the user to hold the sealing plug more firmly when twisting it, preventing operational errors caused by hand slippage. Due to the presence of the anti-slip pattern, the user can turn the sealing plug more easily, thereby quickly and accurately pulling it out of the air inlet hole so that the suction cup can quickly lose its adsorption force.
