Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
An air freshener unit consisting of a box-like base, a motor carried by said base, an air propeller operatively connected to said motor for propulsion thereby, battery means electrically connected to said motor, feet mounted on the underside of a floor pan of said boxlike base to space the underside thereof away from a contact surface, said floor pan having a series of vertically disposed apertures for the intake of air, said base further including a separator to isolate said battery from said motor, a cover for said base, engageable therewith to control the flow of air through the unit, said cover having a series of radially extending air directing means mounted on the underside thereof, a refresher element removeably secureable to the underside of said cover, said element containing a volatilizeable liquid, said cover including a plurality of openings therein for the egress of air whereby said motor when actuated, air is directed into said unit to impinge upon the underside of the element, around the periphery of said element over the top thereof, and to egress through said openings in said cover.
Claim 2
Dependent Claim
184 words
An air freshener unit consisting of a box-like base, a motor carried by said base, an air propeller operatively connected to said motor for propulsion thereby, battery means electrically connected to said motor, feet mounted on the underside of a floor pan of said boxlike base to space the underside thereof away from a contact surface, said floor pan having a series of vertically disposed apertures for the intake of air, said base further including a separator to isolate said battery from said motor, a cover for said base, engageable therewith to control the flow of air through the unit, said cover having a series of radially extending air directing means mounted on the underside thereof, a refresher element removeably secureable to the underside of said cover, said element containing a volatilizeable liquid, said cover including a plurality of openings therein for the egress of air whereby said motor when actuated, air is directed into said unit to impinge upon the underside of the element, around the periphery of said element over the top thereof, and to egress through said openings in said cover.
Claim 3
Dependent Claim
17 words
The device of claim 1 further including key hole mount means on the underside of said base.
Claim 4
Dependent Claim
25 words
The device of claim 1 wherein the refresher element is a thin disc, frictionally engageable to said cover and adapted to be spaced apart thereof.
Claim 5
Dependent Claim
25 words
The device of claim 3 wherein the outer portion of the X shaped fins terminate horizontally just prior to the periphery of the refresher element.
Claim 6
Dependent Claim
38 words
The device of claim 1 further including a spacer vertically disposed within the cover, in vertical alignment with the separator to further reduce travel of air from the left, or fan compartment, to the right or battery compartment.
Claim 7
Dependent Claim
19 words
The device of claim 1 wherein the motor is a low voltage motor, and the battery is 11/2 volts.
Claim 8
Dependent Claim
14 words
The device of claim 1 wherein the radially extending air directing means is X-shaped.
Claim 9
Dependent Claim
20 words
The device of claim 1 wherein the housing consisting of the floor pan and box-like base is made of plastic.
Claim 10
Dependent Claim
25 words
The device of claim 1 wherein the radially extending air directing means on the underside of the cover are in the configuration of X-shaped fins.
Claim 11
Dependent Claim
41 words
The device of claim 9 wherein said X shaped fins include a first portion of relatively short elevation, and a terminal second portion whose elevation at its terminal point is in a plane corresponding to the underside of said refresher element.
