[0011] By adopting the above technical solution, personnel can tighten or loosen the rubber plug by using the internal thread and the external thread, so as to facilitate placing the rubber plug into the air inlet or taking the air inlet out of the air inlet.

[0012] Specifically, the rubber plug is made of silicone rubber material.
