Abstract

A handheld mechanical soft-surface remediation (SSR) device and method of dislodging, displacing, and disposing of particulates from surfaces and performing disinfection and/or freshening is disclosed. The device is preferably lightweight, easy-to-use and includes a fan assembly, filter assembly, flapper assembly, battery assembly, and chemical delivery system. Performing soft-surface remediation with the mechanical SSR device includes the steps of retrieving the device from storage, installing the consumables into the device, activating the device, performing the cleaning operation, deactivating the device, removing the consumables from device, preparing the device for the next use, storing the device and, optionally, recharging the batteries.

wherein the fan assembly is capable of developing a suction pressure of −

0.15 to −

0.66 pounds per square inch,

wherein the filter assembly includes a filter and a collection tray,

wherein the filter assembly includes a consumable non-woven portion or electrostatic cloth positioned in close proximity to fan blade.

8. The device of claim 2, wherein the filter is at least one of a standard mesh high efficiency particulate air (HEPA) filter or HAF filter.

9. The device of claim 2, further comprising a collection tray positioned near a lower region of a filter in the filter assembly in order to capture particles that will not lodge within filter.

10. The device of claim 2, wherein the filter assembly comprising a filter and a collection tray that are mechanically integrated for ease of access by a user.

11. The device of claim 2, wherein the flapper assembly includes a set of flappers that are arranged parallel to one another and spaced apart to ensure a small air gap therebetween.

12. The device of claim 2, wherein the flapper assembly includes a plurality of flappers that are formed of a rigid lightweight material and include a plurality of holes.

13. The device of claim 2, wherein the flapper assembly includes flappers formed of spring steel;

a disk mechanically coupled to a flapper via an arm;

a pulley mounted at one end of a shaft and driven by a flapper motor via a standard belt; and

a flapper motor that is at least one of a DC motor, an AC motor, a single-speed motor, and a multi-speed motor.

14. The device of claim 2, wherein

the flapper assembly includes a flapper that is a solid piece of material that has no holes;

the flappers are attached at one end to a spring-loaded flapper hinge;

the flapper hinge is mechanically attached in close proximity to the filter assembly;

the hinge provides a pivot point for the flapper;

the spring-loaded hinge provides an appropriate spring force;

the flapper assembly includes a set of disks that are arranged along a shaft; and

the flapper disks are oriented orthogonal to the flappers and are mechanically coupled to flappers via a set of arms.

15. The device of claim 2, wherein when activated, a flapper motor imparts rotational motion to a shaft and, subsequently, to disks.

16. The device of claim 2, wherein the flapper assembly includes a plurality of disks, and wherein each disk has one or more notches into which a curved end of an arm is alternately engaged and disengaged as each disk rotates.

17. The device of claim 2, wherein the flapper assembly includes a plurality of disks are mounted on a shaft such that the notches are in alignment one to another, and wherein at least one disk is mounted on shaft such that its notches are 90 degrees out of phase with those of the other disks.

18. The device of claim 2, further comprising a displacement chamber bounded on two sides by inner walls of a housing body and, on an upper side near disks by an airflow guide.

19. The device of claim 2, wherein the delivery system includes a chemical supply fluidly connected to a spray pump mounted within a handle in the housing;

wherein the flapper assembly includes a flapper that slaps against a soft surface to be cleaned and dislodges particles of contaminants within its fibers in a non-destructive manner.

3. A method of performing soft-surface remediation by use of the mechanical device comprising the steps of:
