Abstract

A portable blower fan assembly that includes a housing that forms a pair of air tunnels. The pair of air tunnels are configured to provide a first airflow path across a surface in a downward direction. The portable blower fan assembly further includes a pair of fan assemblies. Each fan assembly is positioned within one of the air tunnels with a downward angle. The portable blower fan assembly further includes a power supply that is configured to provide electrical power to the first motor and the second motor.

First claim

1 . A portable blower fan device, comprising:
a housing comprising:
a first air tunnel comprising a first intake portion and a first exhaust portion, wherein the first exhaust portion comprises a first pair of focus corners configured to provide a first airflow path in a downward direction from the first intake portion to the first exhaust portion of the first air tunnel; and
a second air tunnel comprising a second intake portion and a second exhaust portion, wherein the second exhaust portion comprises a second pair of focus corners configured to provide a second airflow path in the downward direction from the second intake portion to the second exhaust portion of the second air tunnel;
a first fan assembly disposed between first intake portion and the first exhaust portion of the first air tunnel, wherein:
the first fan assembly comprises a first fan blade and a first motor; and
the first fan assembly is positioned with a downward angle within the first air tunnel to provide the first airflow path in the downward direction;
a second fan assembly disposed between the second intake portion and the second exhaust portion of the second air tunnel, wherein:
the second fan assembly comprises a second fan blade and a second motor; and
the second fan assembly is positioned with the downward angle within the second air tunnel to provide the second airflow path in the downward direction; and
a power supply electrically coupled to the first motor and the second motor, wherein the power supply is configured to provide electrical power to the first motor and the second motor.

2 . The device of claim 1 , further comprising:
an upper housing cover coupled to an upper portion of the housing, wherein the upper housing cover comprises a first pair of channels; and a lower housing cover coupled to a lower portion of the housing, wherein the lower housing cover comprises a second pair of channels.

3 . The device of claim 2 , further comprising a plurality of positioning legs, wherein:
each positioning leg is at least partially disposed within a channel from among the first pair of channels and the second pair of channels; and each positioning leg is configurable to extend at least partially outside of a channel from among the first pair of channels and the second pair of channels.

4 . The device of claim 2 , wherein each positioning leg is configured to be removable from a channel from among the first pair of channels and the second pair of channels.

5 . The device of claim 2 , wherein each positioning leg is configured with an adjustable length.

6 . The device of claim 2 , wherein the lower housing cover further comprises a plurality of vibration dampening feet.

7 . The device of claim 1 , further comprising:
a first curved stator vane disposed at the first exhaust portion of the first air tunnel, wherein the first curved stator vane is configured to apply a rotation to the first airflow path; a second curved stator vane disposed at the second exhaust portion of the second air tunnel, wherein the second curved stator vane is configured to apply a rotation to the second airflow path.

8 . The device of claim 1 , further comprising:
an intake grill configured to cover the first intake portion of the first air tunnel and the second intake portion of the second air tunnel; and an exhaust grill configured to cover the first exhaust portion of the first air tunnel and the second exhaust portion of the second air tunnel.

9 . The device of claim 8 , further comprising:
a cable management system integrated with the intake grill, wherein the cable management system is configured to secure a power cord for the power supply.

10 . The device of claim 2 , wherein the upper housing cover comprises an interface configured to interlock with a lower housing cover of a second portable blower fan device.

11 . A surface drying method, comprising:
positioning a portable blower fan assembly at a worksite, wherein the portable blower fan assembly is configured to provide airflow toward a wet surface, wherein the portable blower fan assembly comprises: a housing comprising:
a first air tunnel comprising a first intake portion and a first exhaust portion, wherein the first exhaust portion comprises a first pair of focus corners configured to provide a first airflow path in a downward direction from the first intake portion to the first exhaust portion of the first air tunnel; and
a second air tunnel comprising a second intake portion and a second exhaust portion, wherein the second exhaust portion comprises a second pair of focus corners configured to provide a second airflow path in the downward direction from the second intake portion to the second exhaust portion of the second air tunnel;
a first fan assembly disposed between first intake portion and the first exhaust portion of the first air tunnel, wherein:
the first fan assembly comprises a first fan blade and a first motor; and
the first fan assembly is positioned with a downward angle within the first air tunnel to provide the first airflow path in the downward direction;
a second fan assembly disposed between the second intake portion and the second exhaust portion of the second air tunnel, wherein:
the second fan assembly comprises a second fan blade and a second motor; and
the second fan assembly is positioned with the downward angle within the second air tunnel to provide the second airflow path in the downward direction; and
a power supply electrically coupled to the first motor and the second motor, wherein the power supply is configured to provide electrical power to the first motor and the second motor;
activating the portable blower fan assembly for a period of time, wherein activating the portable blower fan assembly comprises triggering the power supply to provide electrical power to the first motor and the second motor; and deactivating the portable blower fan assembly after the period of time has elapsed, wherein deactivating the portable blower fan assembly comprises triggering the power supply to disconnect electrical power to the first motor and the second motor.

12 . The method of claim 11 , wherein positioning the portable blower fan assembly comprises at the worksite comprises positioning the portable blower fan to provide an airflow path that is substantially parallel with a floor of the worksite.

13 . The method of claim 11 , wherein positioning the portable blower fan assembly comprises at the worksite comprises positioning the portable blower fan to provide an airflow path that is substantially perpendicular to a floor of the worksite.

14 . The method of claim 11 , wherein the portable blower fan assembly further comprises:
an upper housing cover coupled to an upper portion of the housing, wherein the upper housing cover comprises a first pair of channels; and a lower housing cover coupled to a lower portion of the housing, wherein the lower housing cover comprises a second pair of channels.

15 . The method of claim 14 , wherein the portable blower fan assembly further comprises a plurality of positioning legs, wherein:
each positioning leg is at least partially disposed within a channel from among the first pair of channels and the second pair of channels; and each positioning leg is configurable to extend at least partially outside of a channel from among the first pair of channels and the second pair of channels.

16 . The method of claim 15 , wherein positioning the portable blower fan assembly comprises at the worksite comprises positioning the portable blower fan to provide an airflow
