Abstract
A hand air pump with air accumulation function includes a control valve with a valve block and a control lever switchable between a first operation mode where the plunger assembly is allowed to pump compressed air into an air accumulation tank for accumulation, and a second operation mode where the air accumulation tank is opened to discharge the accumulated compressed air for inflating an attached tire and the plunger assembly is allowed to pump compressed air directly into the attached tire.
