1. An airtight-level sensor for use in an airtight object, comprising:
an air pump having an inlet valve and an outlet valve, wherein the inlet valve is in communication with an accommodation room of the airtight object, and the outlet valve is in communication with the inlet valve;
a sounding mechanism disposed at the outlet valve, and generating a sound wave specific to an air flow entering the inlet valve of the air pump from the accommodation room of the airtight object and exiting out of the outlet valve of the air pump; and
a processing device disposed adjacent to the sounding mechanism for receiving the sound wave, and evaluating an airtight level of the airtight object based on at least a feature of the sound wave.
