An inflating and deflating device for connecting to an inner face of a pad includes a top cover having a first domed portion, an air intake and an air exit aperture; a bottom base connected to a lower side of the top cover; a bottom sealing cap; a deflating button located on the top cover to openably seal the air exit aperture; and a first and a second air locker unit. The bottom base has a second domed portion, which and the first domed portion together define a substantially spherical pump body, and is provided with an air intake and exit aperture. The first and second air locker units respectively openably close the air intake and the air intake and exit aperture. The inflating and deflating device has short airflow path and is airtight, and can be used to both inflate and deflate the pad.
