Description

MOSQUITOES ERADICATING SYSTEM

This invention relates to an environmentally friendly system for eradicating flying

insects and particularly for eradicating mosquitoes.

Flying insects and particularly mosquitoes not only cause nuisance to humans but also animals. Mosquitoes bites cause itching and welts that can subsequently become infected, and mosquitoes may carry debilitating and fatal diseases such as malaria, encephalitis, West Nile virus, and HIV which can transmit to humans. Some fatal viruses are transmitted by mosquitoes from diseased birds or other mammals. A filarial parasite can be transmitted by

mosquitoes to dogs to cause heart worm disease. The heart worm nematodes of such disease can lodge in the heart tissue of a dog to cause death if untreated.

There are numerous species of mosquitoes which commonly lay their eggs in water

and the larvae will mature into adult mosquitoes in two to three days. Some species of mosquitoes will lay their eggs in damp soil, vegetation or other organic matters, or even salt

marshes. The eggs can remain dormant until they are flooded and conditions are favorable for hatching into larvae which are carried by the flood water to lakes and rivers.

Adult mosquitoes prefer to live in calm, damp and shady or dark areas; and they become rather inactive in lighted areas or under the sun. Only female mosquitoes suck blood which they require for producing and laying eggs.

Numerous devices and methods have been developed for eradicating mosquitoes. Chemical pesticide sprays or smoke have been used for eliminating mosquitoes; however,

the chemical substances in the pesticides may cause either short term or long term harmful

medical side effects to humans and damages to the natural environment. Devices emitting bright light or gas have been used to attract mosquitoes and to destroy them; however, large number of such devices also inherently destroy all flying insects including beneficial insects such as bees, butterflies and moths. Some devices employ fire hazardous gas such as a mixture of carbon dioxide and propane to attract mosquitoes in order to annihilate them. Such devices are highly dangerous in use due to the potential fire hazard. Other devices require regular maintenance care or frequent replacement of component parts or replenishment of material used in them in order to operate. Some devices require household electrical supply to operate so that they must be located in close vicinity to an electrical outlet. Therefore, they are not suitable for outdoor use. All such known devices and methods are ineffective in eradicating mosquitoes. Chemical sprays or ointments for applying on the exposed skin of

humans would deter mosquitoes from approaching the exposed skin to deliver bites but they do not eradicate the mosquitoes so that the mosquitoes will survive to find other unprotected victims.

It is the principal object of the present invention to provide a system for eradicating mosquitoes particularly female mosquitoes seeking a favorable environment for laying eggs.

It is another object of the present invention to provide a device which is operative in any indoor or outdoor location.

It is another object of the present invention to provide a device which is relatively maintenance-free .

It is yet another object of the present invention to provide a device which does not

cause any pollution to the natural environment and is effective in operation of eradicating mosquitoes..

Other objects will be in part apparent and in part pointed out hereinafter with reference to the accompanying drawings in which

Figure 1 is perspective front elevation view of the device according to the present invention. Figure 2 is a side and rear elevation view of the device.

Figure 3 is an enlarged partial sectional side elevation view of the main housing and

water container of the device according to the present invention with some of the components shown in schematic form. Figure 4 is an enlarged perspective front and top view of the organic material interior container located in the main housing of the device according to the present invention.

With reference to the drawings wherein like reference numerals designate corresponding parts in the several different views, the mosquitoes eradicating device 10

according to the present invention has a main housing 11 which is generally rectangular in shape having a top panel 12, a left side panel 13, a right side panel 14 and a rear panel 15.

Either the left side panel 13 or the right side panel 14 may be removable to provide access to the interior 16 of the main housing 11. A lower duct 17 extends vertically downwards from the bottom panel 18. A large front opening 19 is located in the front of the main housing 11. The large opening 19 is surrounded by a front frame 20. The interior surface of all panels of the main housing 11 are preferably painted black or other subdued dark color in order to provide a shady-like environment in the interior 16 to form an alluring habitat for mosquitoes. An electrified conductive grid 21 is mounted on the front frame 20 and covering completely

over the front opening 19. A protective mesh 22 having openings about 0.5 mm² is located behind the front opening 19 and is mounted on an inner extension frame 23 on the front frame 20 such that the protective mesh 22 is positioned in a spaced manner behind the electrified conductive grid 21. The protective mesh 22 prevents small insects from entering into the main housing 11 through the front opening 19. A louver panel 24 is provided in front of the electrified conductive grid 21. The louver panel 24 includes a top panel 25 having an L- shaped upper edge 26 for mounting the louver panel 24 to the main housing 11. The louver panel 24 has a plurality of horizontal slats 27 sloping outwardly and downwardly to prevent

rain water from falling onto the electrified conductive grid 21 to cause it to malfunction. The transverse openings 28 between the horizontal slats 27 of the louver panel 24 have a small height of not more than 5 mm so as to prevent children from touching the electrified

conductive grid 21 by accident and it also prevents relatively large harmless insects such as butterfly and dragonfly from coming in contact with the electrified conductive grid 21. The top panel 25 of the louver panel 24 also slopes downwardly and forwardly to provide a protective canopy over the electrified conductive grid 21. An interior container 29 is located in the main housing 11. The interior container 29 has a plurality of open top compartments 30 such that various selected organic materials may be placed in these separate compartments so

as to enhance the enticement of the main housing 11 to mosquitoes. An electrical high speed fan 31 is mounted at the rear panel 15 in the interior of the main housing 11 and it is operated for a very short period of about 20 seconds in a pre-set interval for blowing the remains of the

electrocuted mosquitoes which may adhere onto the electrified conductive grid 21 or other foreign matters such as spider webs from the louver openings 28. A long life LED light 32 is provided in the main housing 11. The LED light 32 will be turned on with an ambient light

sensor to emit a low intensity violet light to attract mosquitoes to the device 10 in the night time. The operation of the LED light 32 and the high speed fan 31 are controlled by an electrical control circuit 33 mounted in the main housing 11. A bifurcated mounting bracket 34 is provided at the outer surface of the rear panel 15 and it extends therefrom in a horizontal manner perpendicular to the rear panel 15. The main housing 11 may be mounted at a selected position of a vertical post 35 of a stand 36 with the bifurcated mounting bracket 34 and it is secured in place with a mounting bolt 37. The stand 36 has a plurality of divergent legs 38 for supporting the stand 36 with the main housing 11 mounted thereon to position securely on a supporting surface either indoors or outdoors. For outdoor application, the stand 36 may be in the form of an elongated post with a pointed lower end such that it may be inserted into the ground to provide a secure mounting for the

device 10. A water container 39 having an open end upper duct 40 is located beneath the main

housing 11 and it may be mounted on the stand 36 with a cantilever supporting bracket 41.

The upper duct 40 is engageable with the lower duct 17 of the main housing 11 as best shown in Figure 3 such that the interior of the main housing 11 and the water container 39 communicate with one another. A mixture of water 42 and charcoal 43 is placed in the water container 39. The mixture provides a mean to create humidity and a water source that is conducive to female mosquitoes to lay eggs. Alternatively, a mixture of water and other organic material such as wood, leaves, or soil may be used for the same purpose. The mixture of water and charcoal is preferred since it provides a long lasting mean which does not

require subsequent regular maintenance or replacement. The device 10 of the present invention may be used indoor by simply placing it directly on the floor with the water container 39 supporting the entire device. Supporting legs may also be provided at the bottom surface of the water container 39 for such purposes.

The electrical supply for operating the electrical components of the device may be provided by batteries or with solar cells 44 mounted on the top portion of the stand 36 when the device is to be located outdoors. Alternatively, the electrical power may be supplied by batteries or household electrical supply when the device is used indoor.

The moisture emitted from the water and charcoal mixture flow from the water container 39 into the main housing 11 to emit out of the front opening 19 through the

electrified conductive grid 21. This moisture emitted from the device 10 as well as the humid and dark interior of the main housing 11 are particularly attractive to female mosquitoes seeking a water location and a humid environment to reside and to lay eggs. Thus, female

mosquitoes will attempt to enter the main housing 11 resulting in being electrocuted by the electrified conductive grid 21. The device is also attractive to male mosquitoes seeking to mate with female mosquitoes which normally would be found in such environment of the main housing 11 and they would also attempt to enter the device 10 and thus would be

electrocuted by the electrified conductive grid 21.

Various selective organic matters such as vegetation and soil may be placed in the various compartments 30 of the interior container 29 to further create an environment

favorable for female mosquitoes seeking to lay eggs particularly in such organic matters in the natural environment. Salt may also be placed in the compartments 30 to create an environment in the main housing 11 to attract female mosquitoes seeking for a salt mash location to lay eggs.

Since all materials used for attracting the mosquitoes to the device 10 of the present invention are natural materials, thus it operates safely without causing any harmful pollution to the natural environment, or fire hazards or harmful health hazards to humans. It also operates completely maintenance free for a long period of time. Furthermore, it operates to eradicate mosquitoes without killing other beneficial insects.

The device 10 may be used for eradicating other pestilent flies or flying insects by placing materials attractive to the intended flies or flying insects in the interior container 29.

While the present invention has been shown and described in the preferred embodiments thereof, it will be apparent that various modifications can be made therein without departing from the spirit or essential attributes thereof, and it is desired therefore that only such limitations be placed thereon as are imposed by the appended claims.
