Floor pump capable of transmitting air pressure value via wireless transmission to mobile electronic device for indication

A floor pump comprising:

• a base including a supporting portion, at least one supporting leg, and an assembling portion formed in the supporting portion, with the at least one supporting leg radially extending from the supporting portion, with a groove formed in the at least one supporting leg;
• a cylinder mounted on the base and having a chamber;
• a hose assembly including a hose, a nozzle, and a recess connected and in communication with each other, with the nozzle attachable with an inflatable;
• a valve assembly mounted in the base and connected between the cylinder and the hose assembly;
• a piston rod connected with a piston, with the piston slidably disposed and reciprocable inside the chamber for pushing air unidirectionally passing through the valve assembly and the hose assembly into the inflatable:
• and a pressure sensing device disposed in the recess and interconnected with the valve assembly, with the pressure sensing device arranged in an isobaric area formed between the hose assembly and the inflatable and including a wireless transmission circuit board, a sensing unit, and a power supply unit, with the sensing unit and the power supply unit electrically connected with the wireless transmission circuit board, with the sensing unit capable of measuring an air pressure value of air flowing into the recess, and with the wireless transmission circuit board connectable with a mobile electronic device via wireless transmission for indicating the air pressure value, and wherein the base includes a connecting hole formed at one end thereof, with the assembling portion, the connecting hole and the groove connected and in communication with each other.
