Abstract

The invention relates to an air charging device which comprises a plenum chamber and a pump device which comprises an inflator pump with a first working air hole, and a first vent hole and a second vent hole, both of which are communicated with the plenum chamber. When the plenum chamber is charged, the first working air hole can lead the air outside the plenum chamber to enter the plenum chamberthrough the second vent hole; when the plenum chamber is discharged, the first working air hole can lead the air inside the plenum chamber to flow out of the plenum chamber through the first vent hole; wherein, when the plenum chamber is charged, the second vent hole is opened and meanwhile the first vent hole is closed. By adopting the structure, an eclectic air pump is integrated with the plenum chamber so as to form an integrated air charging device which can be directly charged with air to become a usable air charging device and is convenient for use and taking along.
