Abstract:
An ELECTRONIC FRAGRANCE EMITTING SYSTEM FOR MOTORED VEHICLES. The system consists of a plastic reservoir which houses liquid fragrance, and a pump that extracts liquid fragrance from the reservoir and transports it to a holder mounted in the passenger air vent. Action is initiated by a button mounted on the dashboard or console. The precise amount of fragrance extracted is controlled by an event timer mounted under the dashboard. Once fragrance enters holder it is quickly absorbed via a felt pad. AC Heater or vented air entering vehicle cabin will then distribute fresh scent.

Description:
WHAT IT RELATES TO 
     The present invention relates to a system that emits a pleasant aromatic scent. 
     HOW IT DIFFERS 
     Fragrant devices producing such a scent have been widely used in homes and in vehicles. This is well known. Unfortunately, some devices scents deplete quickly, thus requiring replacement of the entire device. Others being complicated in structure require the dexterity of a surgeon to refill. Furthermore, they are of the stick-on, hang or variety, and while appearing to be convenient, certain devices cause driver distraction and can actually detract vehicle ergonomics. This system will be integrated within the vehicle (under the hood &amp; beneath dashboard). Activator button used will be of O.E.M. type and will be logically placed. 
     MY OBJECTIVES 
     It is the intention of this inventor to provide an operational, virtually trouble free (user need only to refill reservoir, and have felt element replaced around every two year period), integrated Unit within the vehicle that has the capacity to generate a constant fresh scent upon users discretion, while providing an almost infinite life span. 
     BRIEF SUMMARY 
     A system in harmony with this invention comprises a plastic molded reservoir--which houses the liquid fragrance, mounted under the hood. Reservoir being semi-transparent--an electric pump of lightweight construction mounted next to reservoir which when engaged (via event timer) transfers a predetermined amount of liquid from reservoir to a circular holder mounted inside vehicle passenger vent. Holder houses a felt element which quickly absorbs liquid fragrance--a portion of element being exposed so when air passes through vent--the scent will be emitted into vehicle cabin. All action is initiated via a logically mounted button--(console or dash) which is tied into an event timer mounted under the dash board.

     DETAILED DESCRIPTION 
     FIGS. 1-4 comprise the entire (system) of this invention. It includes all parts of the system. Following is a detailed description of FIGS. 5-18 as well as FIGS. 1-4--turn now to the drawings and initially to FIG. 1 which comprises a completely circular holder having a top cap 1 and bottom container (or holder) 2, both pieces being formed out of an injection molded plastic. The top circular cap 1 as well as the bottom holder 2 have a small round opening 3 in its side that allows a thin flexible plastic piece 9 called a filler tube to be inserted. Once the top cap is screwed down, the two holes will line up 3. The top portion of cap 1 has a cut out 32 (FIG. 9) that allows for a square shape piece of felt element 8 to be placed inside of said holder 1 and 2. 
     The bottom half of holder (or container) 2 has threads 33 of FIG. 10 that allow top cap 1 (also having threads) 40 (FIG. 18) to screw on securely. In the holder 2 resides a partition 34. This partition 34 is not an added piece snapped in, but rather formed as one piece with bottom holder 2. During the plastic forming process--this partition, has its wall extend to both sides of the holder, bottom of partition being flush with bottom of holder, and the top of partition being even with top of holder 2 (FIG. 10). This is in effect creating two separate unequal bowls or containers within bottom holder 2. The front or main container 36 making up 75% of entire space. The rear container 37 making up the remaining 25% (FIG. 10). The partition will have a small hole 35 placed near top. This is for safety reasons--should front container unexpectedly rise to unwanted levels all excess liquid france will quickly be drained away into safety side of container 37 and passed on via safety drain line 6. The mounting stem 4 and safety drain line 6 will, like the partition be formed as one piece with bottom holder--through an injection mould process--and are not attached externally by snapping on or glue on means. 
     As was stated the drain lines purpose is to prevent overflow of the system. Its round opening 6 of FIG. 9 will be of sufficient means. The drain line 6 (FIG. 1) will attach to a rubber hose 7 (FIG. 1) that will allow excess liquid to be redirected back to reservoir 19 (FIG. 3). The felt element 8, made of an absorbent material, will sit flush on the floor of bottom container 2 in front of partition 34 on larger side of holder 36 (FIG. 10) having only a portion of element extruding from top cap 1 (FIG. 11). The stabilizer 38 (FIGS. 9 and 14) will keep element 8 stable. It (stabilizer 38) is only a slight rise or indention which is formed during the injection process. The device (holder) will be kept secure in the vehicle vent dual via a pal nut 5 (FIG. 10) that slips over mounting stem 4. Two small holes are made in the air duct floor to allow mounting stem 4 and drain line 6 access to mount. Bottom of holder 2 fits flush with the bottom of the air duct (FIG. 15). A small incision is placed in the side of the air duct to allow thin plastic filler tube 9 access to the holder (FIG. 15). The filler tube is inserted into a small hole on holder 3 (FIG. 1). Once button 30 (FIG. 2) is engaged, liquid fragrance is transferred to holder 2 via filler tube 9, the adapter 10 (FIG. 1) allows the smaller filler tube 9 to connect to larger hose 11 (FIG. 1)(Adapter and Filler Tube both formed of a plastic construction). The rubber hose 11 (FIG. 1) used is installed along the passenger side of the vehicle (FIG. 17)(most cases) and a small hole or opening is made in the fire wall of the vehicle to allow the hose access to the passenger cabin, and more specific to passenger air vent 39 (FIG. 17) where the holder resides (FIG. 15 and 16), the opposite end of the hose being attached to outlet end 14 of an electric pump (FIG. 4) mounted under the hood of the vehicle next to reservoir 19, the inlet side of pump 13 also having a hose 16 attached will connect to pick-up tube 17 of FIGS. 3-8 that is mounted inside of plastic rectangular shape reservoir 19 (FIG. 3). Reservoir 19 houses liquid fragrance until small measured amounts are called upon and transferred to the holder in the cabin of the vehicle. The pick-up tube 17 is responsible for picking up (drawing) liquid out of reservoir 19 via pump 12 (FIG. 4). Both reservoir and pick-up tube will be made of a plastic semi-transparent material--so fluid levels can be easily monitored--pick-up tube will have a rubber grommet 18, that can be slid up its shaft 17 (FIG. 8). Its job is to keep the pick-up tube securely mounted inside of the hole in reservoir 19. The bottom side of the reservoir (FIG. 7) shows drain plug 23. The rubber hose 24 (FIG. 3) is flexible and permits user ability to drain reservoir 19 of contents should user desire to switch scents before--running out. The cap 25 (FIG. 3) is easily removed and reapplied. The reservoir has extrusions 31 (FIGS. 6-7) and mounting screws 22 allowing it to be mounted to a support bracket. Reservoir can be easily filled by unscrewing cap 21 (FIG. 6) adding liquid fragrance and replacing cap. All action is initiated via a button 30 (FIG. 2) mounted in a logical position. Button will be tied into a brain (black box) 26 (FIG. 2) mounted beneath the dashboard (FIG. 17). Its contents will contain an event timer that controls the amount of time pump 12 (FIG. 4) will run. Time can be varied to compensate for different hose lengths, position of holder etc. (Variations made internally by installer and not by the user of the system). Black box 26 has three separate lines out--all lines will be of an RCA type. The RCA plug is used for ease of maintenance--should event timer require it. You would simply slip RCA plug out, thus leaving activation button mounted intact. Along with the other two lines--one other to pump 12 (FIG. 4) and the last being tied into the battery giving unit its needed current. 
     OPERATION OF SYSTEM 
     Only a predetermined amount of liquid fragrant will be emitted upon engagement of activator button 30. Button must be re-engaged in order to repeat process--the precise amount transferred to holder 2 is gradually absorbed by felt element 8. Scent is then released throughout vehicle cabin. Venetian blinds, and/or air condition &amp; heating speed controls will regulate scent distribution and intensity. The holder 1-2 has been so designed as to minimize unnecessary air flow restrictions. The circular shape allows unrestricted air passage around its body. The felt element 8 being fairly square shape in design insures the trapped scent will be picked up by the passing air. Variations and modifications are possible without departing from the spirit of the invention.
