CROSS REFERENCE TO RELATED PATENT APPLICATION

The current application claims the benefit of the earlier priority filing date of the provisional application, Ser. No. 61/328,743, that was filed on Apr. 28, 2010 and this application is a continuation of U.S. patent application Ser. No. 13/096,414 filed Apr. 28, 2011 and entitled “AIE SCENT DISPENSER”, the disclosure of which is incorporated by reference herein.

FIELD OF THE INVENTION

The present invention relates generally to an air filter scent dispenser device and more specifically relates to a scent dispenser device that is engaged to an air filter for infusing the air passing through the air filter with scent, which is carried throughout the HVAC ductwork and into the habitable portions of a structure.

BACKGROUND OF THE INVENTION

In any place where people gather there will be various odors, fragrances and the like. It is common for homeowners and businesses to oftentimes struggle to maintain pleasant smelling environments. Many odors from such various things as cooking, personal hygiene products, the presence of pets, and cigarette smoke can be present in a home or business. Odors of these types are often difficult to combat. As such, a large industry has developed dedicated to the removal and/or masking of these odors. Products such as scented sprays, odor eliminating cleaning products, fans, and air purifiers and filters are now commonly found in homes and businesses. In addition, scent dispersion products such as scented candles and electric scent dispersers are now commonly used and widely available.

Despite the wide variety of readily available devices, products, and apparatuses available to help control or eliminate odors, each and every product suffers from the same limitation, its use is localized to a particular vicinity of use. Specifically and by way of example, use of a scented spray only affects the area in which the spray is used. So, another room in the house or business will not be affected by spraying a scented spray in a separate room. Likewise, electric scent dispersers and candles are only able to disperse scents in the room in which they are used. If one desires to disperse scents in multiple locations or rooms, one must use a product or device in each room. This is both time consuming and expensive.

Thus, a need exists for a device or product that is able to disperse a scent into all rooms in a home or business simultaneously. Further, a product is needed that allows a homeowner or business proprietor to selectively dispense scents into the premises with the ability to control the amount of scent dispersed. Still further, a need exists for a product that can remove odors or scents from the entire home or business without having to be transported from one room to another.

DETAILED DESCRIPTION OF THE INVENTION

Referring now specifically to the drawings, a scent dispenser device for engagement to an air filter is illustrated in FIG. 1 and collectively shown generally at reference numeral 10. The air filter 12 comprises a media 14 that is composed of a non-woven web for blocking particulate matter carried by the air through common HVAC ductwork. The media 14 is folded in accordion fashion to form a plurality of V-shaped pleats, and is housed in a rectangular, paper-board frame 16. The scent dispenser device 18 comprises a base 20, an adjustable valve 22, and a cap 24.

The base 20 of the scent dispenser device 18 may contain a plurality of troughs 26. The troughs 26 may be aligned side-by-side and serve as the bottom portion of the base 20. The apex of each trough 26 may be engaged to a circular rim forming the top portion of the base 20. A locking hub 28 is positioned within the center of the base 20 and contains a centrally located bore 30 and retention slots 32. The retention slots 32 are spaced an equal-distance around the bore 30. As illustrated, the locking hub 28 may contain three equally, spaced-apart retention slots 32 around the bore 30, but any number of retention slots 32 may be disposed on the locking hub 28 depending upon the desires of the user.

The base 20 is designed to retain a scented media, such as scented beads or scented polypropylene. The troughs 26 as described above are best equipped to retain a plurality of scented beads within the trough. As air passes through the troughs 26 and over the beads, the air is infused with scent that then exits the scent dispenser device 18. In another alternative embodiment, the bottom portion of the base 20 may be relatively flat to retain scented polypropylene, which could be in disk or strip form. The beads may possess the same scent or may have different scents that we mixed together produce a pleasant aroma. Alternatively, the scented polypropylene may contain only one scent, but may also contain multiple scents that when mixed together produce a pleasant aroma.

The adjustable valve 22 includes a plurality of inner resiliently flexible fingers 34 and a plurality of outer resiliently flexible fingers 36. The inner resiliently flexible fingers 34 are positioned in close proximity to the center point of the adjustable valve 22. The outer resiliently flexible fingers 36 are positioned in close proximity to the outer edge of the adjustable valve 22. Each flexible finger (34, 36) has an upper portion and a lower portion and contains an inner collar 38 and an outer collar 40, as shown in FIG. 4. The upper portion of the flexible finger (34, 36) is engaged to the adjustable valve 22 and the bottom portion extends perpendicularly downward from the adjustable valve 22. The outer collar 40 is positioned in close proximity to the lower portion of the flexible finger (34, 36). The inner collar 38 is positioned between the lower portion and the upper portion of the resiliently flexible finger (34, 36). The inner resiliently flexible fingers 34 are designed to be selectively secured to the base 20 and are positioned within the retention slots 32 disposed around the bore 30 of the locking hub 28.

The adjustable valve 22 is generally circular in shape and the outer portions of the adjustable valve 22 extend beyond the periphery of the cap 24. The adjustable valve 22 may contain directions or instructions, as illustrated in FIGS. 1 and 6. As shown in FIGS. 1 and 6, the adjustable valve 22 contains the terms “on” and “off.” These terms refer to the position of the cap 24 for allowing air to flow over the scented media contained within the base 20 and for preventing air from flowing through the scented media. When the indicator tab 42 of the cap 24 is positioned in the “on” position, air is allowed to flow through the scented media contained within the base 20 and the air is infused with scent. When the indicator tab 42 of the cap 24 is positioned in the “off” position, air is prevented from flowing through the scent media and the air is not infused with scent. A stop 44 is disposed on the adjustable valve 22 that engages a rib 46 disposed on the underside of the cap 24. The stop 44 prevents the cap 24 from rotating 360°. Instead, the stop 44 only allows the cap 24 to rotate 180° between the “on” and the “off” position.

As illustrated in FIG. 5, the adjustable valve 22 contains a second air passageway 48 that opens into the base 20. As illustrated, the second air passageway 48 takes the form of a grill 48, having a criss-cross structure. The grill 48 is positioned on a half of the adjustable valve 22 and is semi-circle in shape. The grill 48 allows air to flow through the base 20 and over the scented media. A grill 48 is illustrated but any passageway that allows air to flow is acceptable. The grill 48 allows air to flow into the base 20, while also retaining the scented media, particularly scented beads, within the base 20. The cap 24 contains a cover 50 positioned on the underside of the cap 24. The cover 50 is composed of raised ribs and entirely covers the grill 48 when the cap 24 is in the “off” position. In other words, when the cap 24 is in the “off” position, the cover 50 is over-top and completely covers the grill 48, thus preventing any air flow through the grill 48. As the cap 24 is rotated to the “on” position, the cover 50 is removed from the grill 48 incrementally, thus allowing air to flow through the grill 48. When the cap 24 is rotated to the “on” position, the cover 50 is completely removed from the grill 48, thus allowing unrestricted air flow through the grill 48. A user may adjust the amount of scent in the air by rotating the cap 24 between the “on” position and the “off” position.

The frame 16 of the air filter 12 includes a grid that covers the back side of the media 14. The back side is meant to refer to the side opposite the direction of air flow. The grid, as shown in FIG. 1, consists of parallelograms, generally rectangular or square shapes. A single circular area is positioned within the grid for receiving the scent dispersion device 18. A retention ring 54 is positioned between the media 14 and the circular area of the grid of the frame 16. The retention ring 54 is designed to receive the scented dispersion device 18. The retention ring 54 contains a plurality of inner ledges 56 that are designed to receive the outer resiliently flexible fingers 36 of the adjustable valve 22. The outer collar 40 of the outer resiliently flexible finger 36 engages the inner ledge 56, forming a selectively secured arrangement. The inner collar 38 of the outside resiliently flexible finger engages the outer edge of the base 20, as shown in FIGS. 7 and 8. As illustrated in FIG. 5, the inner ledges 56 are spaced-apart and equal-distance around the inner periphery of the retention ring 54. The retention ring 54 and circular area of the grid may contain corresponding bores 56 for receiving a retention pin 58 that is disposed on the underside of the adjustable valve 22. When the retention pin 58 is inserted into the retention bores 58 disposed on the retention ring 54 and circular area of the grid, the scent device 10 is retained to the air filter 12.

The adjustable valve 22 contains a centrally located bore 60 with at least one air passageway 62 disposed adjacent the bore 60. As illustrated in FIG. 2, three spaced-apart air passageways 62 are disposed adjacent the bore 60. It will be known to one of ordinary skill in the art that any number of air passageways 62 may be disposed adjacent the bore 60 for allowing air to pass through the adjustable valve 22. The bore 60 is designed to receive a post 64 disposed perpendicularly downward from the cap 24. The post 64 is positioned within the bore 60 in a rotationally secure arrangement allowing the cap 24 to rotate with respect to the adjustable valve 22.

FIG. 3 illustrates the direction of air flow through the scent device 18. Air flows through the media 14 of the air filter 12 and a portion of the air flows through the bore 30 of the base 20. Afterwards, the air then progresses through the air passageways 62 of the adjustable valve 22 and contacts the underside of the cap 24. The air then ricochets downwards through the grill 48 (assuming the cap 24 is in the “on” position or is allowing air to flow through the grill 48) and the air contacts the scented media, such as scented beads, located in the troughs 26 of the base 20. After the air is infused with scent, the air travels upward through the grill 48 and then exits the scent device 18 through at least one arcuate exit hole 66 disposed on the side of the cap 24. If the cap 24 is in the “off” position, the air is prevented from entering the grill 48 and the base 20; therefore, the air travels out of the arcuate exit hole 66 without being infused with scent and traveling through the grill 48 and base 20.

Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention and are intended to be covered by the following claims.
