DESCRIPTION
DESC:FIELD OF THE INVENTION


In general the present invention relates to a device for dispensing fumes of repellent liquid to the environment. More particularly, the present invention relates to a smart insect repellent liquid vaporizer with PIR sensor and predefined mode of operations.


BACKGROUND OF THE INVENTION


Many types of insects and other nuisance bugs are considered pests, because they transmit diseases, damage structures or destroy agricultural products. Parasitic insects, such as mosquitoes, biting flies and bedbugs are notorious for decreasing the enjoyment of the out-of-doors for humans and pets alike.


Mosquito threat is a worldwide problem. Diseases like malaria, filariasis, Dengue fever, yellow fever, Japanese encephalitis, Ross river virus, Burma forest virus, Murrcey Valley encephalitis etc, are known to spread through mosquitoes. Even developed countries like US have seen a renaissance of mosquito’s’ danger and diseases like west Nile virus in the 21st century. The options for pest control are generally limited to killing/capturing or repelling technique.


The art has addressed this difficulty in various ways. For example, US Patent No. US7712249 B1 discloses about an ultrasonic repellent humidifier for dispersing insect repellent in the air as a micro fine repellent vapour. A repellent tank provides rhodinol and cedarwood oil based repellent to a repellent well. An ultrasonic transducer is positioned in the well beneath the level of the repellent. It vibrates, forming a repellent vapour that is drawn into a vapour duct by a forced air system and out of the unit, dispersing the repellent vapour into the surrounding air. The vibrating portion of the ultrasonic transducer that is exposed to the oil-based repellent is a ceramic material that inhibits residue from forming on the transducer that reduces its efficiency. The ceramic material may be formed on the metal case of the transducer or on the piezoelectric oscillation crystal, or it may be a separately replaceable disc.


The art has also produced a variety of heat driven devices for dispensing insect repellent materials into the air. Typically such devices include housing, an air inlet and outlet with an airflow path extending there between, a heat source vaporizes the insect repellent liquid and vapours are dispensed to the air through a stem. A number of these heat driven devices utilize electricity to vaporize the insect repellent liquid.


An important problem for a user of a heat driven device to dispense a volatile material is detecting or predicting the quantity of repellent liquid to be dispensed in the environment and detecting the level of repellent liquid remaining in the refill. This especially can be important when the volatile is an insect control agent used in a sleeping room, for example, so that an empty refill may mean an irritating midnight mosquito attack, with the attendant risk of mosquito-borne disease, or excess release of fumes of repellent liquid to the closed environment may cause breathing problems and other diseases.


Various other devices exist in the art, and those referred to, above, are by way of example only. The art is still in need of a device that provides an easy means for a user to control the quantity of repellent liquid to be dispensed in environment and automatically trigger the dispensing the vapours of repellent liquid in closed environment by identifying the presence of human in the environment.
