Abstract
Abstract An air treatment apparatus operating in conjunction with a conventional type of air conditioning apparatus through which air moves in an air stream. The air treatment apparatus is to be loaded with any one of a plurality of interchangeable cassette type containers. Each container is to contain a particular type of a liquid substance such as an air freshening chemical. The air treatment apparatus is to be electrically controlled to operate through a pump to be dispensed as a plurality of short bursts of the substance within the air stream of the air conditioning apparatus at preselected intervals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
253 words
In combination with an air conditioning apparatus, said air conditioning apparatus having a housing, air movement means mounted within said housing, said air movement means producing an air stream, an air treatment apparatus being in fluid communication with said air stream, said air treatment apparatus being for emitting an atomized substance into said air stream, said air treatment apparatus comprising: orifice dispensing means located within said air stream; a cassette receiving chamber formed within said housing for enclosing and securing a source means therein; conduit connection means comprising a male section and a female section; source means containing a quantity of a substance in liquid form, said source means comprising a cassette, said cassette having a valve assembly, said valve assembly being mounted within an outlet tube having a connection end comprising said female section, mounted within said cassette, said cassette being removably connected to said male section by said connection means so that said male section is engageable with said valve assembly, said cassette being located within said cassette receiving chamber when it is connected to said male section; and pump means mounted within said housing, said pump means being fluidly connected to said source means via an inlet tube connected to said female section and said pump means also being fluidly connected to said orifice dispensing means, said pump means being for moving said substance from said cassette past said valve assembly into said inlet tube to said orifice dispensing means so that it is emitted therefrom as a fine spray.
Claim 2
Dependent Claim
253 words
In combination with an air conditioning apparatus, said air conditioning apparatus having a housing, air movement means mounted within said housing, said air movement means producing an air stream, an air treatment apparatus being in fluid communication with said air stream, said air treatment apparatus being for emitting an atomized substance into said air stream, said air treatment apparatus comprising: orifice dispensing means located within said air stream; a cassette receiving chamber formed within said housing for enclosing and securing a source means therein; conduit connection means comprising a male section and a female section; source means containing a quantity of a substance in liquid form, said source means comprising a cassette, said cassette having a valve assembly, said valve assembly being mounted within an outlet tube having a connection end comprising said female section, mounted within said cassette, said cassette being removably connected to said male section by said connection means so that said male section is engageable with said valve assembly, said cassette being located within said cassette receiving chamber when it is connected to said male section; and pump means mounted within said housing, said pump means being fluidly connected to said source means via an inlet tube connected to said female section and said pump means also being fluidly connected to said orifice dispensing means, said pump means being for moving said substance from said cassette past said valve assembly into said inlet tube to said orifice dispensing means so that it is emitted therefrom as a fine spray.
Claim 3
Dependent Claim
72 words
The combination as defined in claim 1 including: electrical control means connected to said pump means, said electrical control means being manually activatable to activate said pump means, said electrical control means including time interval variation means to select a specific desired time interval from a plurality of different time intervals at which said pump means would be activated resulting in emitting said atomized substance into the air within said air stream.
Claim 4
Dependent Claim
279 words
In combination with an air conditioning apparatus, said air conditioning apparatus having a housing, air movement means mounted within said housing, a duct assembly included within said housing, said duct assembly being for receiving air from said air movement means and directing such into ambient air, and an air treatment apparatus connected to said duct assembly, said air treatment apparatus being for emitting an atomized substance into the air as the air passes through said duct assembly, said air treatment apparatus comprising: orifice dispensing means located within said duct assembly; a cassette receiving chamber formed within said housing for enclosing and securing a source means therein; conduit connection means comprising a male section and a female section; source means containing a quantity of a substance in liquid form, said source means comprising a cassette, said cassette having a valve assembly, said valve assembly being mounted within an outlet tube having a connection end comprising said female section, said outlet tube being mounted within said cassette, said cassette being removably connected to said male section by said connection means so that said male section is engageable with said valve assembly, said cassette being located within said cassette receiving chamber when it is connected to said male section; and pump means mounted within said housing, said pump means being fluidly connected to said source means via an inlet tube connected to said female section and said pump means also being fluidly connected to said orifice dispensing means, said pump means being for moving said substance from said cassette past said valve assembly into said inlet tube to said orifice dispensing means so that it is emitted therefrom as a fine spray.
Claim 5
Dependent Claim
279 words
In combination with an air conditioning apparatus, said air conditioning apparatus having a housing, air movement means mounted within said housing, a duct assembly included within said housing, said duct assembly being for receiving air from said air movement means and directing such into ambient air, and an air treatment apparatus connected to said duct assembly, said air treatment apparatus being for emitting an atomized substance into the air as the air passes through said duct assembly, said air treatment apparatus comprising: orifice dispensing means located within said duct assembly; a cassette receiving chamber formed within said housing for enclosing and securing a source means therein; conduit connection means comprising a male section and a female section; source means containing a quantity of a substance in liquid form, said source means comprising a cassette, said cassette having a valve assembly, said valve assembly being mounted within an outlet tube having a connection end comprising said female section, said outlet tube being mounted within said cassette, said cassette being removably connected to said male section by said connection means so that said male section is engageable with said valve assembly, said cassette being located within said cassette receiving chamber when it is connected to said male section; and pump means mounted within said housing, said pump means being fluidly connected to said source means via an inlet tube connected to said female section and said pump means also being fluidly connected to said orifice dispensing means, said pump means being for moving said substance from said cassette past said valve assembly into said inlet tube to said orifice dispensing means so that it is emitted therefrom as a fine spray.
Claim 6
Dependent Claim
72 words
The combination as defined in claim 1 including: electrical control means connected to said pump means, said electrical control means being manually activatable to activate said pump means, said electrical control means including time interval variation means to select a specific desired time interval from a plurality of different time intervals at which said pump means would be activated resulting in emitting said atomized substance into the air within said duct assembly.
