Abstract:
A handheld vacuum cleaner, comprising: a suctioning unit (10), which is provided with an air outlet end; a dust-gas separation unit (20), which is separably connected to one end of the suctioning unit (10) and coaxially arranged with the suctioning unit (10); a handle (30), which is connected to the other end of the suctioning unit (10) and coaxially arranged with the suctioning unit (10), the interior of the handle (30) being hollow, so that a hollow cavity is formed; a power supply unit (50), which is detachably provided in the hollow cavity of the handle (30); and an outflow air filtering unit (40), which is separably provided on the outer side of the suctioning unit (10) in the axial direction of the handle (30), wherein the outflow air filtering unit (40) is arranged at the air outlet end and is coaxial with the suctioning unit (10). The handheld vacuum cleaner simplifies operation steps of dust removal, and improves the user experience; a filtering effect on the air outlet end is improved; the effect of endurance of the power supply unit (50) on use of the handheld vacuum cleaner by a user is reduced, and the holding effect of the handheld vacuum cleaner by the user during use is improved.
