Abstract
Provided are an internal and external dual-purpose air pump, an inflatable product and a lifting handle device; the internal and external dual-purpose air pump includes a machine core, including a housing having an accommodating chamber and an inflating device arranged in the accommodating chamber; the housing is provided with an air outlet and an air suction inlet respectively in the bottom and top ends, and the air outlet and the air suction inlet can both communicate with the accommodating chamber; and the housing is slidably connected with a buckling member, which can move relative to the housing, thereby the machine core is buckled into or detached from a product to be inflated through the buckling member; the inflating device works to send air flow out through the air outlet and/or suction air flow through the air suction inlet. The inflatable product includes the internal and external dual-purpose air pump.
