AIR TREATMENT CHEMICAL DISPENSER HAVING ANGLED DISPERSION OF CHEMICALS
First Claim
9. A device for dispensing an air treatment chemical, the device comprising:
- a housing including an inlet for permitting air to enter into an interior space of the housing and including an outlet for permitting air mixed with air treatment chemical to exit the interior space, wherein the inlet is provided below the outlet on the housing;
a substrate positioned within the housing, the substrate bearing the air treatment chemical;
a power supply mounted within the housing;
a motor mounted within the housing, the motor being powered by the power supply; and
an impeller mounted within the housing and connected to the motor, the impeller comprising an enclosed impeller having multiple channels,wherein the housing provides a convergent-divergent channel in which the mixture compresses, at a converging section, toward a throat of the convergent-divergent channel and expands, at a diverging section, away from the throat and through the outlet of the housing.

Abstract
A device for dispensing an air treatment chemical includes a housing having an inlet for permitting air to enter into an interior space of the housing and an outlet for permitting air mixed with air treatment chemical to exit the interior space of the housing. A substrate positioned within the housing bears the air treatment chemical. A power supply mounted within the housing powers a motor mounted within the housing. The motor is connected to an impeller mounted within the housing. The impeller moves air from the inlet adjacent the substrate to mix the air treatment chemical into the moving air and deliver the mixture of air and air treatment chemical through the outlet to outside of the housing. The housing includes a transitional body defining a convergent-divergent channel for compressing the mixture at the converging section and expanding the mixture at the diverging section.

12-1. The device of claim 9, wherein the multiple channels of the impeller include about 10 channels to about 20 channels.
-
13-2. The device of claim 9, wherein the convergent-divergent channel defines about a 75 degree to about a 105 degree angle having a vertex at the throat of the channel.

18. A device for dispensing an air treatment chemical, the device comprising:
-
a housing including an inlet for permitting air to enter into an interior space of the housing and including an outlet for permitting air mixed with air treatment chemical to exit the interior space; a plurality of substrates mounted within the housing, each of the plurality of substrates bearing the air treatment chemical; a power supply mounted within the housing; a motor mounted within the housing, the motor being powered by the power supply; and an impeller mounted within the housing and connected to the motor, the impeller being capable of moving air from the inlet adjacent the plurality of substrates so as to mix the air treatment chemical into the moving air, and then deliver a mixture of air and air treatment chemical through the outlet to outside of the housing, wherein the housing provides a convergent-divergent channel defining a flow pathway for the mixture, wherein the mixture compresses at a converging section toward a throat of the convergent-divergent channel and expands at a diverging section away from the throat and through the outlet of the housing, and wherein the impeller delivers the mixture at an inclined emission angle with respect to a plane defined by a top covering of the housing. - View Dependent Claims (19, 20)
