SHEET 10F 2 ROOM ODOR CONTROL RELATED APPLICATION This application is a continuation-in-part application of the Valbona and Voglesonger application Ser. No. 264,135 now U.S. Pat. No. 3,829,071 filed June 19, 1972.

BACKGROUND OF THE INVENTION Heretofore, the major portion of a concentrated odor control liquid dropped upon a fast revolving surface splashes off to a limited area or puddle having comparatively very little surface in contact with moving air. This greatly reduces potential vaporization and invites repeated manual applications for a quick odor build-up effect which ultimately results in a long continuing heavy aeration of the liquid which may become undesirably intense and be rather wasteful.

SUMMARY OF THE INVENTION Incorporation herein by reference is expressly made of said application Ser. No. 264,135 essentially for the disclosure and use of the upper tubular feeder for liquid concentrate to have a scent that begins promptly with the actuation of the dispenser or the manual charging thereof and operates at a sustained pleasant scent level.

In the further embodiment of the invention set forth herein, a readily removable font of concentrate is reciprocably mounted with a depending outlet nozzle, preferably valved, which when pressed downwardly discharges a limited quantity of liquid upon the upper face of a spring blade located parallel to and above a continuously rotating porous disk. As the font is pressed downwardly to discharge the liquid on the blade, it engages the blade and flexes it into wiping contact with the surface of the disk. The blade preferably is provided with a capillary slot disposedtangentially to the circular path of engagement with the disk and this slot terminates marginally at the trailing edge of the blade contact. With this arrangement even a small quantity of liquid concentrate is progressively wiped and spread onto and into the porous disk over a substantial area where it will be in immediate contact with entraining air. Any additional liquid that might be dispensed by repeated reciprocations of the container will be moved into potential storage in deeper portions of the porous plastic due to successive compressions and expansions induced on the rapidly rotating .disk when the blade is in contact therewith in the same path. This quickly charges the disk for a lasting effect.

To provide versatility, the disk is readily removable for .washing or replacement to remove any earlier scent when selecting another, and when reinstalled, it readily dries itself for immediately renewed dispensing of a new scent when charged therewith.

Container fonts can be easily interchanged by withdrawal and reinsertion of another one in a carrier.

Fresh air is drawn over the motor and warmed by cooling the motor to reduce its humidity and then vaporizes and entrains odor control liquid from the rough-surfaced disk as it si propelled thereby fro a soft discharge flow.

DESCRIPTION OF PREFERRED EMBODIMENT Referring more particularly to the drawings, a housing 10 is provided defining a motor compartment 12 having an electric motor 14 supported therein on depending studs 15 as located adjacent to inlet ventilation openings 16 in a vertical wall 18,

The shaft 20 of the motor extends downwardly on an axis disposed eccentrically to the circular marginally flared bottom wall 22 of the housing 10 and supports in a driving relation a rotatable disk 28 releasably secured thereto. A horizontal air baffle 24 peripherally separates the disk from the motor compartment 12 and has an air passage or opening 26 therethrough. As the disk 28 is rotated at motor speed, air is drawn through the inlet openings 16, over the motor, and down through the portal 26 of the disk 28.

The disk 28 preferably is a circular section cut from a sheet of porous expanded plastic and has open porous rough surfaces 40 on all sides. When rotated the rough surfaces mildly but positively centrifugate air outwardly in a radial direction with an intimate interface contact therewith by which any moisture on the disk is entrained and carried away by the air.

The disk 28 is supported on the lower end of the motor shaft 20 by a plastic foraminated circular element 30 of plastic having a longitudinally split hub 32 encircled by a C-spring 34 which urges the hub sections to slidably clamp on the motor shaft.

Four radially and angularly spaced upstanding pins 36 on the rim of the disk 28 (FIG. 3) have heads 38 on them and shoulders 48 to serve in locating the porous disk 28 coaxially on the spider 30. A foraminated plastic washer 42 having openings 44 that receive the heads 38 in snap relation to rest against the shoulders 48 supports the porous disk preferably without compressing it. The removal of the assembly from the shaft and the foraminated washer from the pins releases the porous disk for removal, washing and remounting, or replace ment.

The supply assembly 50 of odor control liquid comprises a tubular container 51 (FIG. 4) telescopically replaceable in a cup-like carrier 53 that is externally offset or grooved to provide a downwardly facing shoulder 52. The container 51 is terminally tapered at the lower end 54 to provide a discharge opening 56 normally closed by a plunger valve 58 urged by a spring 60 to a closed position with a stem 62 on the valve extending beyond the lower end of the container for its actuatable displacement. The supply assembly 50 is received from the top in a tube 63 for the carrier 53 to extend above the top of the housing 10 in its resting position, and, the

3 tube 63 is radially open along one side as at 64 from a shoulder 66 to the bottom end thereof beyond which the container extends in guided relation.

A whip spring 68 (FIG. 4) is supported on hangers 71 integral with the housing 10 to intersect the interior of the tube 63 through the opening 64 at the shoulder 66 to engage the shoulder 52 in the container 50 in resilient supporting relation so that the container can be finger-pressed from above downwardly towards the disk 28. The spring 68 yields to permit this and then returns the container to its resting position.

Below the valve 58 in container 50 a leaf spring 70 is supported by a screw 72 as inclined slightly to the upper face of the disk 28 in the direction of its rotation (arrow 74) and is normally spaced a slight distance above it (FIG. 4). The end of the spring 70 has'a small opening 76 (FIG. 5) through it in close proximity to the end 58 of the valve and from this opening the blade is split through to its end to provide a capillary slit 80. Then when the container 50 is pressed downwardly (FIG. 6), the nipple 62 on on the valve 58 engages the spring blade 70 and opens the valve 58 to permit a limited amount of liquid to flow onto the blade 70 and from there into the hole 76, and through the slit 80 as the blade 70 is brought into contact with the rotating porous disk 28. Withthe disk turning, the blade progressively compresses the porous disk in a circular path while the liquid is spread from the slit 80 into contact with the compressed disk in the path. Then as the wetted compressed portion progressively leaves contact with the blade, reexpansion of the porous disk body absorbs the liquid and prevents its being twirled from the surface 40. Thereafter, the liquid re-surfaces gradually to be progressively vaporized by the air turbulating at the rough surface of the disk and be entrained thereby as the air is set into motion and circulated by the disk.

The container 50 is easily withdrawn and is semitransparent so that the remaining supply of liquid can be ascertained from time to time and replaced when empty without disturbing the device.

Adhesively mounted tabs 82 (FIG. 3) of soft elastomer engage and hold the baffle 24 in place where they are folded around an axial flange 84 on the housing. A bottom closure member 86 has an upstanding axial flange 88 which overlaps the depending flange 84 to also engage the tab 82 is assembled relation.

The disk 28 is disposed off-center in the circular housing as enclosed by the bottom closure member 86 carrying a circular shroud 90 (FIG. 2) closely following approximately 160 of the disk edge 92 on the internal side of the eccentricity. This provides an exhaust chamber 96 having narrow throats 98 and 100 at each end of the shroud 90. The closure member 86 has radial exhaust openings 102 in its chamber wall adjacent to the downstream throat 100 and extending approximately 125. With this arrangement, air impelled by the disk through the upstream throat 98 has a chance to expand in the wider portion of the chamber 96 and be urged to escape through the circumferential openings 102 as it approaches the narrowing downstream throat 100, yet can return to contact with the lower side of the disk for further mixing and later escape through the exhaust openings 102 with minimized and practically unnoticeable sound of air movement.

The operation and structure of the device has been concurrently explained and it is to be noted that in absence ofa liquid supply container, liquid can still be applied to the blade through the container tube 63 for a run-off pick-up by the porousldisk 28'before or during rotation without a drop bounce which could carom or splash a substantial amount of liquid from the disk. Moreover, the bottom 86 is easily removed and cleaned along with the disk to prevent foreign odors accumulatmg.

Suitable wiring, not shown, by an extension cord with a switch carried by the cord is provided, preferably for continuous full speed operation.
