Embodiment Construction

[0046] It has been recognized that dispensers of air treatment agents can be made more efficient by utilizing sensing technology to control when and how much air treatment agent should be dispensed.

[0047] Devices using specialized chemical sensors for airborne pollutants or specialized odor sensors have been disclosed. However, it has been recognized that the cost of such devices and their sensitivity and accuracy, or rather their characteristics, are not advantageous. Therefore, to address the stated problem, it has been recognized that off-the-shelf sensors that detect changes in the concentration of chemical pollutants in the air are cost-effective sensors that can be used in conjunction with dispensers of air treatment agents, where the chemical in the air Sensed as odor, aroma, etc.

Abstract

The present invention relates to a dispensing device for at least one air treatment agent comprising at least one airborne agent detector operable to detect airborne agents in the air; receiving means for receiving at least one source of air treatment agent; and control means for releasing an amount of at least one air treatment agent from a source thereof received in the receiving means when a current airborne agent level detected by the airborne agent detector deviates from a background airborne agent level detected by the airborne agent detector by more than a predetermined amount, wherein the background airborne agent level is calculated by the device. The present invention also relates to a method of dispensing at least one air treatment agent.

Description

technical field [0001] The present invention relates to dispensing equipment for air treatment agents, and more particularly to dispensing equipment for air treatment agents used in spaces for deodorizing and removing odors. Background technique [0002] Air fresheners and other air treatment agents are used in a wide variety of applications, such as in homes, vehicles, and elsewhere. A user-programmable automated air freshening device has been proposed in which the dispensing mechanism is turned on and off periodically. These systems are suitable when it is possible to predict when the activator needs to be dispensed; but not if, for example, unpleasant odors or other substances enter the air at irregular intervals. [0003] Efforts have been made to design an air freshener that dispenses fragrance, deodorant, or disinfectant only when the room is occupied, and utilizes infrared detectors to detect motion within the room or space. [0004] The need for effective release o...
