The low-pressure air charging assembly and the high-pressure air charging assembly can not work simultaneously all the time, so that the load of the motor is reduced, and the service life of the motor is prolonged.
Example 4: a high-low pressure electric inflator pump (refer to attached figures 1, 2, 3, 6 and 7) is similar to embodiment 1 in structure, and mainly different in that a fan blade is sleeved on an output rotating shaft in the embodiment, and a one-way bearing is connected between the fan blade and the output rotating shaft.
