The present invention relates generally to the field of air fresheners. More specifically, the present invention relates to an air freshening device that can easily be attached to residential or commercial heating, ventilation and air conditioning (HVAC) system vents to disperse fresh scents, and utilizes the forced air being pushed through the ventilation system to distribute the scent throughout the area. The air freshening device preferably comprises a clip designed to attach the air freshening device to the HVAC vent, a fragrant material, and a reservoir attached to the clip for holding the fragrant material, wherein the HVAC blower causes the fragrant material stored in the reservoir to be dispersed throughout the room via the forced air. Also, the air freshening device may further comprise an adjusting mechanism to enable the user to adjust the amount of fragrant material that is dispersed during any particular period of time. Accordingly, the present specification makes specific reference thereto. Nonetheless, it should be appreciated that aspects of the present invention are also equally amenable to other like applications, devices and methods of manufacture.
Keeping a room or other enclosed space clean and fresh smelling is a laborious and never-ending battle in many homes and offices. Stale odors, poor circulation, tobacco smoke, food odors, pet odors, and the like all combine to offend the olfactory senses of anyone entering a room, and may cause embarrassment to the homeowner or other person responsible for maintaining the cleanliness of the space.
By way of background, most commonly used air freshening devices used in the home and other enclosed spaces consist of incense sticks, diffusers, scented candles, aerosol sprays, or aromatic balls, which are placed into an area where the air needs to be freshened. However, many of such devices take up floor space, have a limited range of effectiveness and/or detract from the aesthetics of the home. Additionally, many of said air freshening devices may be harmful to children and pets. For example, scented candles are a well-documented fire hazard, particularly when left unattended, and incense sticks and aroma balls may be both poisonous and/or a choking hazard to, for example, a dog or a young child. Moreover, many of such air freshening devices are typically single use devices that must be discarded once used or consumed, and it can be expensive to have to routinely replace the same with new products.
It has also been a common practice to use room air fresheners in the form of a sponge or matrix-like material containing a scented product or ingredient which is then released into the surrounding air as the product is suspended by a string, hook or the like from a support. However, such devices are not aesthetically pleasing, and can interfere with individuals moving around in the enclosed space (e.g., if suspended from a ceiling in the middle of the room). Still other air freshening devices are comprised of a housing that holds a volatile material in connection with an electrically heated vapor dispensing device. However, such air freshening devices require an electrical connection, either through a normal electrical supply or a battery, and can therefore be costly to operate and/or replace.
Additionally, a common problem with all of the above referenced air freshening devices is that the freshening smell is overpowering at first, and then the aroma quickly diminishes over time. Also, there is no mechanism to regulate the strength of the fragrance of the air freshening device to suit the needs and preferences of the user. Another common problem with traditional air fresheners is that the freshening aroma is not evenly distributed throughout the room or other enclosed space, and is only concentrated in the area in which it is located and/or released. More specifically, once the scent or fragrance is released, no means is provided for the distribution thereof. Stated differently, existing air freshening devices do not take advantage of the forced air or HVAC sources already servicing the room or enclosed space, and require the user to purchase a separate can, nozzle, or aerosol for distributing the fragrance, which can be expensive, time consuming, and requires disposal after use.
Therefore, there exists a long felt need in the art for an air freshening device that utilizes an existing HVAC ventilation system to force the scented air or fragrance into the room or other enclosed space in an efficient manner, and that evenly distributes freshening aroma throughout the entire room or enclosed space. There is a long felt need in the art for an air freshening device that allows a user to regulate the strength of the fragrance being emitted from the air freshener device to suit the needs and preferences of the user, and that easily and quickly attaches to an HVAC vent. Additionally, there is a long felt need in the art for an air freshening device that is refillable and that enables users to choose from different types of scents and fragrances. Moreover, there is a long felt need in the art for an air freshening device that is relatively safe for children, pets, and elderly individuals that may have a breathing condition, and that may further comprise anti-bacterial, anti-viral, anti-microbial and/or anti-fungal properties. Finally, there is a long felt need in the art for an air freshening device that is relatively inexpensive to manufacture, safe and easy to use, and that eliminates odors and distributes a pleasant fragrance into a room or other enclosed space with the assistance of forced air emanating from an existing HVAC system.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises an air freshening device to be used as an attachment to an existing HVAC vent. More specifically, the air freshening device comprises a clip for releasably attaching to, for example, a fin of an HVAC vent, a fragrance reservoir having a user selectable and refillable fragrance contained therein, and an adjusting mechanism for adjusting the amount of the strength of the fragrance being dispensed. The fragrance may be in the form of a gel, a mesh, an air freshener strip, a fabric or the like, and may be further comprised of one or more of an anti-bacterial, anti-viral, anti-microbial and/or anti-fungal solution or formulation.
In this manner, the air freshening device of the present invention accomplishes all of the forgoing objectives, and provides a relatively quick and easy solution to dispersing fresh scents and fragrances evenly into a room or other enclosed space according to the needs and/or preferences of the user. The improved air freshening device of the present invention is also simple in both design and use, economical, efficient in its construction and installation, and eliminates the need to purchase unnecessary and additional accessories to properly function.

Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
The description refers to provided drawings in which similar reference characters refer to similar parts throughout the different views, and in which:
The innovation is now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.
As noted above, there is a long felt need in the art for an air freshening device that utilizes an existing forced air system, such as an HVAC ventilation system, to efficiently and thoroughly disperse a scented fragrance into an enclosed space, such as a room. There is also a long felt need in the art for an air freshening device that allows a user to regulate the amount of the fragrance being emitted from the device to suit the needs and preferences of the user, and that is removably attachable to a forced air vent. Additionally, there is a long felt need in the art for an air freshening device that is self-activating, refillable with various different fragrances, and that may further comprise at least one of an anti-bacterial, anti-viral, anti-microbial and/or anti-fungal solution. Finally, there is a long felt need in the art for an air freshening device that is relatively inexpensive to manufacture, safe and easy to use, and that eliminates odors and distributes pleasant fragrances into a room or other enclosed space with the assistance of forced air emanating from an existing HVAC system.
The innovative product of the present invention features an air freshening device for attachment to an HVAC vent and that comprises a clip, a supply or reservoir for containing and dispensing a fragrant material, a fragrant material stored in the reservoir and an adjusting mechanism. The adjusting mechanism allows the user to control the amount of fragrance that is released from the device into the forced air being expelled from the HVAC vent. The forced air, in turn, carries the fragrant material for distribution throughout an entire room or enclosed area to be treated. The fragrant material may be stored in the reservoir in many forms including, without limitation, a mesh, strips, a gel, a solid, a liquid or the like, and may further comprise at least one of an anti-bacterial, anti-viral, anti-microbial and/or anti-fungal solution or formulation for al so killing any germs, bacteria, viruses, or airborne pathogens.
Therefore, a novel air freshening device is disclosed having a user selectable and controllably released fragrant or scented material that is stored in a reservoir or supply chamber of the device and introduced into a forced air stream for distribution throughout an entire room. By way of background, the normal air flow for an HVAC unit in an average sized room ranges from 400 to 2,000 cubic feet per minute (CFM) depending on the location of the measurement, and the dimensions of the associated duct work. A standard or desirable amount of air flow for an enclosed space is roughly 1 cubic foot per minute per the square footage of the area to be heated or cooled. The present invention is designed to work with an HVAC unit having an airflow circulation of between 400 and 1,000 CFM, and more preferably between 400 and 800 CFM, though the same should not necessarily be construed as a limitation on the usefulness of the air freshening device of the present invention.

More specifically,
Notwithstanding, the air fresher device 100 may have a plurality of fragrance strength levels for the user to choose from (i.e., it's not limited to just the three referenced above). The mode selected by the user by sliding the button 1221 controls the opening and closing of the vents 302 on front surface 1100 of the housing, as best shown in
The fragrance strength adjusting mechanism 122 is preferably attached to an outer body of the device 100, such as housing 110, to provide easy access to the user. However, the position of the fragrance strength adjusting mechanism 122 is not limited to the outer surface, and the strength adjusting mechanism 122 can be positioned at any position as per the user preferences, including hidden within housing 110 and wirelessly adjusted. More specifically, for controlling the device 100 remotely, the user may install a corresponding software application on a compatible smartphone device or any other electronic device, and may connect to the air freshening device 100 over a wireless network connection such as Wi-Fi, Bluetooth, NFC, RFID, or the like.
As previously stated, a user may control the amount of the fragrant materials 124 to be released from the device 100 by utilizing the fragrance strength adjusting mechanism 122 on the housing 110. The strength adjusting mechanism 122 can be in other forms, such as a touch button, a push button, a fragrance adjustment dial or the like. For example, in one embodiment having a plurality of adjustably sized openings in the housing 110, a user can control the amount of fragrant materials 124 released by turning a fragrance adjustment dial in a clockwise or counterclockwise motion, thereby modifying the size of the plurality of openings from large to small and vice versa.
The housing 110 structure may be made up of plastic, metal, or any other suitable material that provides a protective outer covering for the reservoir 120, and provides longevity to the air freshening device 100. Further, the housing 110 of the air freshening device 100 may be made up of surgical grade stainless steel, having anti-corrosion and/or hypoallergenic properties. The housing 110 may also be of any color, design, print, logo, trademark or the like 140 to enhance the aesthetic look of the air freshening device 100.
The reservoir 120 may be of a shape similar to the shape of the housing 110, such that the reservoir 120 fits inside the housing 110, or may take another shape which is easily removable from the housing and replaceable (e.g., a replaceable cartridge). More specifically, the reservoir 120 is removably coupled to the housing 110, and comprises a fragrant material 124. The fragrant material 124 may be in the form of a mesh, strips, a gel, sticks, solids, liquids, absorbent materials (e.g. sponges) and the like. The reservoir 120 can be accessed by opening the lid 112 and, once the reservoir 120 is accessed, the lid 112 can be closed.
In one embodiment of the present invention, the fragrant material 124 is a gel or other composition that is diffusible and exhibits no flow (or very slow flow) at room-temperature so that the gel or other material substantially maintains its shape during use. The fragrant material 124 may also have different scents such as lavender, rose, lemon grass, cinnamon, vanilla, pumpkin spice, combinations thereof or the like, and the fragrant material 124 can be selected as per the preferences of the users. Alternatively, a suitable fragrant material 124 may be made by mixing a desired fragrant oil in a liquid petroleum distillate diluent such as Isopar M, thereby producing the fragrant liquid 124.
As best shown in
Nonetheless, the extended flexible arms 1301 of the clip 130 can also be relatively short in length, or may be of any other shape as per the design requirements of the device 100. For purposes of illustration, but not limitation, attaching device 130 may be selected from any known devices in the art such as hook and loop fasteners, “S” hook fasteners, pins, barbs, clips, clamps, adhesives, tapes, magnetic fasteners, etc. The clip 130 enables the air freshening device 100 to be releasably attached in any of a horizontal, vertical or perpendicular position relative to the vent or register face, such that the openings in the device 100 are generally parallel to the direction of air flow, subject to the angular adjustment referenced herein. The clip 130 may be made of any suitable material, such as metal, plastic or the like. In a further embodiment of the present invention, the air freshening device 100 may be mounted to the vent, grill any other device, such as a vehicle air conditioner vent, table fans, or the like, using the clamping mechanism 130, which enables the device 100 to release the fragrant materials 124 into the surroundings through the force of the air received from the air flow device.
The clip 130 can be removed when the air freshening device 100 is not in use, and may be easily reattached to the rear surface 1102 of the housing 110 when the user needs to use the air freshening device 100. More specifically, the clip 130 can be removably attached to the housing 110 or the HVAC vent by means of a push lock mechanism, or the like. For purposes of illustration, but not limitation, attaching means may be selected from any means known in the art such as hook and loop fasteners, “S” hook fasteners, pins, barbs, clips, clamps, adhesives, tapes, magnetic fasteners, etc. In this manner, the clip 130 is easily replaceable in the event of loss or if the same becomes broken.
In operation, the user turns on the HVAC device 300 so that it starts blowing a stream of air through the vents 301. As the air stream leaves the vent 301, it is forced to, in part, pass through the openings or vents 202 on the back 1102 of the housing 110. A reservoir 120 having fragrant material 124 receives the air from the HVAC unit through the vents 202 on the back 1102 of the housing 110 and infuses the same with the fragrant material 124 so that it is dispersed through the vents 302 present on the front surface of the housing 110 and into the entire room or other enclosed space. Further, the amount of fragrant material 124 released is easily controllable by the user via the angular placement of the device 100 relative to the vent 301 and/or by utilizing the small adjusting mechanism 122 as previously described on the housing 110 of the device 100.
As previously mentioned, in an embodiment, a companion smartphone app is provided to regulate the operation of the freshener device 100. More specifically, the app connects to the device 100 through a Wi-Fi, Bluetooth, NFC or other wireless connection technology, where a small wireless connection chip (not shown) is present in the interior of the air freshener device 100. In this manner, a user can remotely customize the time, duration and scent level with functionality provided in the companion smartphone app.
In another embodiment, the air freshener device 100 of the present invention uses scented permeable material 124 protected through a shell or housing 110 that attaches to any forced air vent. More specifically, the fragrance is emitted whenever the forced air system is active and air passes through the scented permeable material. In one embodiment of the invention, the overall size of the freshening device 100 may be approximately four to six inches square for use in conjunction with a typically sized residential HVAC system. The device 100 is available with multiple fragrances 124, which may be phthalate-free, paraben free, and International Fragrance Association (IFRA) compliant.
In another embodiment, the air freshening device 100 of the present invention may use cold air diffusion technology, which works by using high amounts of vibration, such as ultrasonic vibrations to compress oils into a dry mist of nano particles of the size described above or 0.1 to 25 microns. The use of cold air diffusion technology ensures consistent and subtle scenting of a room or other enclosed space without high or low points in the scenting process.
In view of the foregoing, it can be seen that the air freshener device 100 of the present invention employs an air freshener releasing device 100 in combination with a forced air stream derived from a conventional forced air system normally installed in a house, office building or the like. More specifically, the air freshening device 100 is detachably connectable to an output vent, wherein the forced air emitted therefrom is forced past a reservoir of fragrant materials 124 to achieve distribution or a fragrance or scent throughout a room or other enclosed space. It should be noted that the air freshening device 100 of the present invention does not require the use of aerosols, harmful solvents, propellants, electricity, batteries, or child-endangering plug-in units. Further, the air freshening device 100 is comprised of environment friendly materials, and is both reusable and recyclable.
