The air control system module is detachably mounted on the suction cup body, and the air control system module is connected to the adsorption chamber. The suction cup device disclosed in patent CN 219827440 U can utilize the air control system module to vacuum the adsorption chamber of the suction cup body.

[0003] However, the suction cup device disclosed in patent CN 219827440 U also has the following technical defects: First, the air control system module of the suction cup device relies on batteries for power supply. When the battery is exhausted, it must be charged with an external battery cable. The battery capacity is limited, which limits the endurance of the suction cup device. Second, although the suction cup device is provided with a button to start the suction process of the suction cup body, there is no switch between the battery and other control units. When the suction cup device is no longer in use, the power supply cannot be completely cut off, which reduces the endurance of the battery. Summary of the Invention

When the air pressure detection sensor detects that the pressure inside the suction cup is less than the set value, the MCU main control module automatically turns on the vacuum pump.
