Benefits of technology

[0011]The dust prevention and removal device of the present invention removes dust, allergens, and other particulate material from the air and surfaces proximate the device, so that the user dusts less often. The device comprises a housing defining an interior space. The housing includes an inlet with a filter disposed therein for drawing air through and an outlet for expelling air. The interior space includes a motor in communication with a power source for delivering and powering thereof. The motor includes an output shaft in communication with a double-sided radial fan for driving the fan. The double-sided radial fan includes an upper portion having a plurality of blades disposed thereon and a lower portion having a plurality of blades disposed thereon. The fan vertically draws air through the inlet and filter to remove some dust, allergens and other particulate matter therefrom. The air is circulated within the interior of the housing where the airflow is rotated 90 degrees to a substantially horizontal airflow wherein it is circumferentially disposed out of the device through the outlet thereof. In a preferred embodiment of the present invention, the outlet airflow is directed onto the surrounding surface substantially reducing the amount of dust on the nearby surface.
[0012]The filter element of the present invention is preferably a thermoformed nonwoven filter capable of trapping some dust, allergens and other particulate matter present in the air. The filter is substantially visible, but not obtrusive, so the user can determine that the filter is collecting dust and change the filter when it becomes saturated with particulate matter. Further, the filter element is preferably disposable such that once the filter element becomes substantially dirty; it may be easily replaced by the user.

Problems solved by technology

In many household environments, a number of airborne particulates, e.g., allergens, dust and / or other airborne matter are present which can create respiratory problems for individuals residing within the home.
However, the vast majority of devices of this type have relatively complex constructions that require significant time and expense to assemble and maintain.

second embodiment

[0087]FIGS. 26A-26C illustrates the lock and key assembly 473 of the device 410 of the present invention. In the current embodiment of the lock and key assembly, the upper portion 414 of the housing 412 secures a filter frame portion 482 between the upper projection 438 of the device 410. Accordingly, the filter 452 is snap-fitted therebetween to secure the filter 452 into place. In one embodiment (not shown) the filter 452 is heat stake bonded to the filter frame 482 and preferably requires a separation force from filter frame of more than 0.113 kilograms (kg.) (0.25 pounds (lbs.)) while the insertion and removal force of the filter frame holding the filter from the device is at least 0.9 kg (2 lbs.) and no greater than 1.8 kg (4 lbs.).

third embodiment

[0088]Turning to FIGS. 27A-27C, a lock and key assembly 573 of the device 510 includes a lever 586 to actuate a switch 588. The lever is hingedly connected to an interior surface of the housing 512 preferably below the motor 556. A spring 589 is positioned between the lever and the bottom surface of the housing 512. An actuation rod 590 is longitudinally disposed through the center of the device 510 in communication with the motor 556 and lever 586. The actuation rod 590 is configured to engage a receiver 591 on the grill 544. The lock and key assembly 573 is configured such that when a filter 552 is pushed into place on the grill 544, the actuation rod 590 is engaged such that the actuation rod contacts the lever 586 and biases the lever 586 downwardly. An arm 587 of the lever 586 is configured to engage the switch 588 to thereby activate the device 510. Accordingly, the device 510 is incapable of operation without the presence of a filter media configured to fit the grill 544. In ...

fourth embodiment

[0089]Referring now to FIG. 28, the lock and key assembly 673 includes switch 688 disposed within the device 610. The grill 644 includes a plunger 694 extending downwardly therefrom and terminating in a lever 686. Accordingly, upon insertion of the filter 652 into the grill 644, the plunger 694 is depressed thereby bringing the lever 686 into communication with the switch 688 to activate the device 610.

Abstract

A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Application Ser. No. 61 / 115,409, filed Nov. 17, 2008, and U.S. Provisional Application No. 61 / 090,372, filed Aug. 20, 2008, the entirety of each is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to dust prevention and removal devices, and, more specifically, to a device for collecting and removing dust and allergens from the air and surrounding environment.[0004]2. Discussion of the Related Art[0005]In many household environments, a number of airborne particulates, e.g., allergens, dust and / or other airborne matter are present which can create respiratory problems for individuals residing within the home. Some such airborne particulates can accumulate on various readily viewable surfaces within the home, which can be aesthetically displeasing.[0006]To manage, control, or otherwise influence the airborne trav...
