Apparently, the described embodiments are merely some rather than all of the embodiments of present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of present disclosure without making creative efforts shall fall within the protection scope of present disclosure.

(12) During specific implementation, as shown in FIG. 1 to FIG. 9, an air pump with an automatic air pumping function includes a shell 1 and a sealing ring 2; an automatic air replenishing mechanism 3 is arranged at one end of the shell 1; a mounting barrel 4 sleeves the other end of the shell 1; the automatic air replenishing mechanism 3 includes a battery mounting box 301 mounted on an inner wall of the shell 1; a battery pack 302 is arranged inside the battery mounting box 301; a vacuum pump 303 is arranged on the inner wall of the shell 1; one end of the shell 1 is clamped with a detection box 304; an air pressure sensor 305 is arranged inside the detection box 304; a two-way valve 306 communicated with the vacuum pump 303 is embedded into the other end of the detection box 304; the sealing ring 2 sleeves a surface of the detection box 304; a shape of the sealing ring 2 is a hollow circular truncated cone; a digital display circuit board 307 is arranged on a surface of the battery mounting box 301; and an output end of the battery pack 302 is electrically connected to an input end of the digital display circuit board 307. During transferring of tiles or when a vacuum suction cup and an air pump need to be used in other aspects, the vacuum suction cup and the air pump are first mounted using the sealing ring 2. The device is first used to make the vacuum suction cup in a set negative pressure state. During use, the air pressure sensor 305 can monitor an air pressure in real time. If an air pressure value is less than a preset value, the air pressure sensor 305 may transmit a signal to the digital display circuit board 307. The digital display circuit board 307 transmits the signal to the vacuum pump 303, and the battery pack 302 provides a driving force for the vacuum pump 303. The two-way valve 306 is used for air pumping, so that an internal pressure reaches a preliminary preset value, and a negative pressure state is achieved.
