When the air charging and discharging device 400 is in the air discharging state, the ozone generator is started to discharge ozone into the exhaust channel, so that the ozone is released into the air bag gap, and the functions of eliminating peculiar smell and sterilizing of the air bag cushion are achieved. By matching with the air leakage state of the air charging and discharging device 400, the ozone produced by the ozone generator can be discharged quickly, is not easy to accumulate in the gaps of the air bags, and protects the safety of users. If the ozone generator is not used for exhausting and only works, ozone discharged into the air bag gap is possibly accumulated around the user, and the concentration of the ozone reaches a limit value to cause harm to the user. Of course, if other harmless gas is used in the sterilizing gas generator 130, it is not necessary to work in conjunction with the deflation status of the inflation and deflation device 400.
