A portable blower has a casing () having an opening portion () open in a suction face () of the casing () facing the installation surface with an inclination and a discharge port () open in a top face () of the casing (); an air passage () inside the casing (), connecting between the opening portion () and the discharge port (); and a blower fan () inside the air passage (). As the blower fan () is operated, outside air is introduced into the air passage () through an intake port () formed by part or the whole of the opening portion () to pass through the blower fan () and then be sent out through the discharge port (). The opening portion () and the discharge port () communicate with each other along the inner side of the suction face () outside the blower fan ().

Portable blower

A portable blower includes a casing () having an intake port () and a discharge port (); an air passage () provided inside the casing () and connecting between the intake port () and the discharge port (); a blower fan () arranged inside the air passage (); a filter () arranged at the intake port (); and a lid portion () openably fitted to the casing (), the lid portion (), when open, exposing the intake port () and, when closed, covering the intake port (). When open, the lid portion () supports the casing () to let it stand on a table top. As the blower fan () is operated, outside air is introduced through the intake port () into the air passage () so as to be sent out through the discharge port ().

Behind a front panel of an air purifier are formed guide paths on the right and left sides thereof. A space between the front panel and a filter unit is partitioned by a partition plate into a front panel rear space and a filter unit front space. Part of an airflow that has entered the guide path through an air intake enters the filter unit front space, and the other part thereof enters the front panel rear space. When entering the front panel rear space, the airflow takes a sharp turn at a sharp turn corner. As a result, coarse dust is separated from the airflow, and the separated coarse dust falls into a dust box.
