An inflation system, a massage pool air supply system, and an inflation method. The inflation system includes: a first gas channel (20) and a second gas channel (30); the first gas channel (20) has a gas inlet port and a gas outlet port; the gas inlet port is used for being connected to a gas supply apparatus (10), and the gas outlet port is used for communicating with a gas chamber (51) of the inflated object (50); the first gas channel (20) can be switched between a first state and a second state; the second gas channel (30) is arranged in parallel to the first gas channel (20); the second gas channel (30) is used for communicating with the gas chamber (51); a gas pressure sensor (40) is provided on the second gas channel (30); in the first state, a gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) does not reach a set value, and the first gas channel (20) can inflate the gas chamber (51); in the second state, the gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) reaches the set value, and the first gas channel (20) can stop inflating the gas chamber (51). The inflation system can prevent over inflation and can effectively protect the inflated object.
