Device Overview

[0041] FIG. 1 shows an insect trap assembly 100 according to an embodiment of the present disclosure. Insect trap assembly 100 includes a housing having a body 101 and a lid 102 that may generally overlie the body 101, which may be generally cylindrical in shape having a grid like structure. In the present embodiment, a trap or capture basket 103 that is supported by the body 101 is constructed to retain insects and is removable from the body 101 for emptying. Lid 102 may be generally circular with a top surface that may include a hanging member 112, for example a hook, for hanging the insect trap assembly from a tree or other structure. It is appreciated that top lid 101 may be defined by other styles of roofing and that the housing is not limited to the geometric configuration shown herein. The housing components may be made of any acceptable material, including for example plastic.

[0042] FIG. 2 is an exploded view of the insect trap assembly 100 of FIG. 1. In the embodiment shown in FIG. 2 the insect trap assembly 100 comprises:

TABLE-US-00001 TABLE I (Insect Trap Assembly - Top Level) Item Function 101 Housing Body Insect trap assembly housing and grid 102 Top Lid Overlies the housing body 103 Capture Basket Repository for dead and dying flies and mosquitos drawn down into the device by the fan 104 Fan Holder Secures Fan 111 to Housing 105 Circuit Board Protects Circuit Board Waterproof Box 106 Circuit Board Components to control timing of device 107 LED indicator Remind user to fill water tank and change CO2 cartridge 108 Movable Gate Part of Housing, allows access to interior of housing 109 UL Power Cord Supply external power 110 CO2 Ultrasonic Creates atomized vapor atomizer unit cloud of CO2 111 Fan Draws mosquitos down into capture basket 103 112 Hook/Hanging Hang insect trap device element from the hook 113 UV Bulb Holder Holds UV bulb 114 UV bulb, “black light” Generates UV light as one attractant

[0043] FIG. 4 is a structural operation flow diagram that illustrates operational features of the insect trap assembly 100 according to one embodiment. Insects attracted to the insect trap assembly 100 are drawn into the trap through a plurality of gaps between posts in the housing body 101 and enter a space between the top lid 102 and the housing body 101 in order to pass to the interior of the housing body 101. The insects pass certain operational features disposed in the interior of the housing and exit the housing body 101 by passing downward into the attached capture basket 103.

[0044] The insect trap assembly utilizes an ultrasonic vibration atomizer 110 to periodically generate an atomized vapor cloud of carbon dioxide (CO.sub.2), which is released into the interior of the housing body 101 to attract insects (first attractant), for example mosquitos and other biting insects. Additional insect attractants for attracting and trapping mosquitos and other biting insects may be utilized with the atomized vapor cloud, such as octenal and an ultraviolet light assembly.

Light Attractant

[0045] Referring to FIGS. 2 and 4, disposed centrally in the insect trap body 101 there is arranged a second attractant comprising a light tube assembly including a bulb holder 113, and light bulb 114 constructed and arranged to illuminate the insects/mosquitos with a wavelength of about 365 nm to 400 nm. In the present embodiment, the light tube assembly 113, 114 is mounted to the body 101 by fasteners, for example mounting brackets and attachment members such as bolts or screws. It is appreciated that there are alternative ways to mount light tube assembly 113, 114 within the body 101 as would be known to those of skill in the art. Light tube assembly 113, 114 is attached to a power source, preferably an AC power supply that is externally provided. An on-off switch (not shown) may also be provided and assume either of two positions and accordingly make or break connections in a circuit to supply or terminate power to light bulb 114, as would be known to those of skill in the art.

Octenal Attractant

[0046] As shown in FIG. 1, a third attractant comprises a source of octenol that is preferably placed in a plastic clip that may hang from the housing adjacent the capture basket 103 and/or the body 101. The plastic lure clip is best shown in FIG. 18. Notably, octenal is a chemical that has been used in combination with CO.sub.2 to attract mosquitos with varying results. While disclosed herein as additional possible attractants, octenal and the light source may or may not be utilized with the CO.sub.2 cloud.

CO.SUB.2 .Cloud Attractant

[0047] Referring to FIG. 3, there is shown an exploded view of the carbon dioxide (CO.sub.2) ultrasonic vibration atomizer 110 shown in FIG. 2. The carbon dioxide (CO.sub.2) ultrasonic vibration atomizer 110 is configured and arranged to periodically generate an atomized vapor cloud of carbon dioxide (CO.sub.2) which is released into the interior of the housing 101 at a level above 2000 parts per million (ppm) periodically for up to 30 days as the first attractant. In the present exemplary embodiment, the CO.sub.2 ultrasonic vibration atomizer 110 is supported on an upper interior portion of the insect trap assembly 100 proximal the top lid 101. The CO.sub.2 ultrasonic vibration atomizer 110 is configured and arranged to generate an atomized vapor cloud of CO.sub.2 periodically, for example approximately once every 24 hours, for a duration of approximately 15 seconds. The CO.sub.2 ultrasonic vibration atomizer 110 is also configured and arranged to detect the quantity of water remaining in the water tank 9. When an insufficient quantity of water is detected in the water tank 9, the indicator light (LED 9) will automatically light up and prompt a user to add more water.

[0048] With continued reference to FIG. 2, the component list of the Ultrasonic Vibration Atomizer includes the following components:

TABLE-US-00002 TABLE II (components of Ultrasonic Vibration Atomizer 110) Item Description Function 1 Telescopic waterproof Ring Seal 2 Nozzle Sprays Water 3 Micro Switch On/Off 4 Exhaust Silicone Tube Balances water pressure 5 Exhaust Pipe plug Top of Exhaust Silicone Tube 6 Probe holder Holds Probe in place 7 Probe Detects if water available 8 Waterproof Ring Seals of Probe 9 Water Tank Holds Water 10 Interface of Water Tank Base of Water Tank 11 Interface with Holds Water Proof Waterproof Ring Ring in place 12 Water Tank Lid Covers water tank 13 Waterproof Ring Seals of Water Tank 14 Water Valve Allows water to flow 15 Tie Rod of Water Valve Part of water valve 16 Tie Rod Spring Part of water valve of Water Valve 17 Storage Cup A Holds first chemical 18 Connector of Storage Connects storage cup “A” Cup A and Cup B to storage cup “B” 19 Storage Cup B and Holds second chemical and CO2 Exhaust provides a means to exhaust atomized CO2 vapor cloud 20 Lid of Storage Cup B Covers Storage Cup B 21 Separator Keeps first chemical separated from second chemical until user mixes them mechanically 22 Ultrasonic Vibration Atomizes water Slice into water vapor 23 Ultrasonic Probe PCB Senses if water present 24 Waterproof Ring of Seal Ultrasonic Probe PCB 25 Atomizer Shell Base of Atomizer 26 Atomizer Bottom Lid Base of Atomizer 27 Overall Bracket of Atomizer Support for Atomizer 28 Circuit Board Fixing Holds PCB Seat of Atomizer 29 Connection Silicone Tranfers water vapor Tube of Atomizer into Storage Cup B

[0049] In use, after starting the insect trap assembly 100, the CO.sub.2 ultrasonic vibration atomizer 110 will provide a consistency of the atomized vapor cloud of CO.sub.2 at a level above 2000 parts per million (ppm) for 30 days, as stated above. This amount of CO.sub.2 is substantially four times (4×) the amount of CO.sub.2 found in the air. Notably, other cycle times and durations are within contemplation of the invention to achieve levels of CO.sub.2 above and below the stated 2000 parts per million (ppm) for 30 days.

[0050] FIGS. 8-11 illustrate various views of the CO.sub.2 ultrasonic vibration atomizer 110. FIG. 8 is a perspective front view of the CO.sub.2 ultrasonic vibration atomizer 110. The front view illustrates that the device is generally comprised of a central portion, a left-hand portion, and a right-hand portion. The left-hand portion comprises the storage cup assembly including storage cup “A” 17, storage cup “B” 19 along with CO2 exhaust. The right-hand portion comprises the water tank 9 and components that support the water tank 9 including the water tank lid 12, the waterproof ring, i.e, seal 13, the telescopic waterproof ring 1 and the water tank interface 10. The central portion comprises those components associated with atomizing the water in the water tank 9 to be fed into storage cup “B” 19 (i.e., the combustion chamber) to generate the atomized vapor cloud of carbon dioxide (CO.sub.2).

[0051] FIG. 9 is a perspective rear view of the (CO.sub.2) ultrasonic vibration atomizer 110 in cross-section cutaway. The rear view best illustrates certain elements of the ultrasonic vibration atomizer 110 not clearly shown in FIG. 8. For example, FIG. 9 illustrates micro-switch 3 which controls timing of the atomizer 110, resetting every 24 hours, and the atomizer shell 25 which acts as a housing to support and protect the ultrasonic atomizer components. Each time the micro-switch 3 is triggered, an ultrasonic wave is created by the mechanical vibration, the wave being directed towards the water in the water storage tank 9 for creating a fine mist of water droplets, i.e. atomization spraying. At the same time, a calculation or countdown begins for the spraying time and the effective service time of the mixture of sodium bicarbonate and aluminum sulfate. After 720 hours, an indicator light (LED 107) is triggered to light up light up, indicating that the mixture of sodium bicarbonate and aluminum sulfate needs to be replace.

[0052] FIG. 10 is a cross-sectional cut-away perspective rear view of the (CO.sub.2) ultrasonic vibration atomizer 110. The cut-away view best illustrates certain elements of the atomizer 110 not clearly shown in FIG. 8 or 9. For example, FIG. 10 illustrates probe 7, which detects if water is available to atomize and ultrasonic vibration slice 22, which atomizes water converting it into water vapor. As is well known to those skilled in the art, the ultrasonic vibration slice 22 operates at a high-frequency oscillation (e.g., 2.4 MHz) whereby liquid water molecules are processed into a flowing mist which results in the release of a large amount of negative ions which reacts with smoke, dust particles and the like floating in the air to cause precipitation.

[0053] FIG. 11 is a further cut-away perspective rear view of the (CO.sub.2) ultrasonic vibration atomizer 110. The cut-away view best illustrates certain elements of the atomizer 110 not clearly shown in FIG. 8. For example, FIG. 11 illustrates ultrasonic probe PCB 23, which activates probe 7 and separator 21, which keeps the two chemical ingredients separated until cover 20 is rotated by approximately 90 degrees.

Method of Operation Flowchart

[0054] Referring now to FIG. 5 a method flowchart illustrating a method for generating an atomized vapor cloud of (CO.sub.2) by the ultrasonic vibration atomizer 110, according to one exemplary embodiment, is shown. The steps are typically performed by a user prior to starting the insect trap assembly 100 for the first time and thereafter after each 30-day refresh.

[0055] At step 502, prior to inserting storage cup “A” 17 into the storage cup assembly 1300, (See FIG. 13, 14) a first chemical, Sodium Bicarbonate, is placed into storage cup “A” 17. Sodium Bicarbonate is selected as a preferable first chemical on the basis of having the property of being comprised of solid molecules that are active and that can generate carbon dioxide (CO.sub.2) easily as a result. Storage cup “B” 19 as one element of the storage cup assembly 1300 is configured and arranged as a combustion chamber inside of which a chemical reaction will occur between the two chemicals and atomized water to thereby generate atomized (CO.sub.2). Preferably, the ratio of Sodium Bicarbonate to Aluminum Sulfate is 1 to 1.

[0056] At step 504, prior to inserting storage cup “B” 19, 1400 into the storage cup assembly 1500, 1600, a second chemical, Aluminum Sulfate, is placed into storage cup “B” 19, 1400. Aluminum

[0057] Sulfate is selected as a preferred second chemical by virtue of having the property of being a solid at room temperature that can readily generate carbon dioxide (CO.sub.2) after hydrolyzation. The property of hydrolyzation may be defined as the splitting of a chemical compound into two or more compounds by reacting with water. Aluminum Sulfate satisfies this property. It is appreciated that other chemicals than those described herein may be used that meet the respective qualifications satisfied by Sodium Bicarbonate and Aluminum Sulfate, as would be known to those of skill in the art.

[0058] At step 506, separator 21 of storage cup assembly 1500, 1600), is inserted between storage cup “A” 17 and storage cup “B” 19, 1400 to keep the two chemicals, (e.g., Sodium Bicarbonate and Aluminum Sulfate) separated in their respective storage cups until such time as the user decides to mix them by mechanical action.

[0059] At step 508, the lid 20 of storage cup “B” 19 is placed over the storage cup assembly 1500, 1600) to prevent the chemical from spilling out of storage cup B.

[0060] At step 510, the lid 20 of storage cup “B” 19 may be twisted by a user to mechanically mix the Sodium Bicarbonate in storage cup “A” 17 with the Aluminum Sulfate stored in storage cup “B” 19, 1400.

[0061] At step 512, post twisting/chemical mixing action by the user, the assembled storage cup assembly is re-inserted into the insect trap assembly 100 with the two chemicals in a mixed state.

[0062] At step 514, as a further preparatory step to generating atomized carbon dioxide (CO.sub.2), the water tank 9 (See FIGS. 2 and 3, a component of the ultrasonic atomizer 110) is temporarily removed from the ultrasonic vibration atomizer 110. The lid of the water tank may be twisted open by a user and filled with water. (See FIG. 17).

[0063] At step 516, the water tank 9 is re-inserted into the ultrasonic vibration atomizer 110. (See FIG. 17.)

[0064] At this point, the insect trap assembly 100 is ready for use and may be turned on with the turn of a single on/off switch.

Device Design Flowchart

[0065] FIGS. 6 and 7 are device design flowcharts of the insect trap assembly 100 that correspond to the method flowchart of FIG. 5.

[0066] At step 602, the device designer must select a first chemical with the property of having solid molecules that are active and that generate carbon-dioxide easily. In a preferred embodiment, Sodium Bicarbonate is selected as the first chemical.

[0067] At step 604, the device designer must select a second chemical with the property of being a solid at room temperature that can readily generate carbon dioxide (CO.sub.2) after hydrolyzation. In a preferred embodiment, Aluminum Sulfate is selected as the second chemical.

[0068] At step 606, the device designer must provide a storage cup assembly 1300 that stores the selected first and second chemicals and acts as a mixing compartment for mixing the two chemicals in coordination with a user action. The storage cup assembly 1300 includes an upper storage cup “A” 17, a lower storage cup “B” 19, a separator 21 for maintaining a separation of the two chemicals respectively stored in the upper storage cup “A” 17 and the lower storage cup “B” 19. In an embodiment, storage cup “B” 19 of storage cup assembly 1300 is shown to include a (CO.sub.2) exhaust component 19 for dispersing the atomized vapor cloud of carbon dioxide (CO.sub.2) out of storage cup “B,” 19. Storage cup “B” is sometimes referred to herein as the “combustion chamber.” Storage cup assembly 1300 further includes storage cup connector 18 configured and arranged to connect storage cup “A” 17 to storage cup “B” 19, and separator 21. Upper storage cup “A” 17 is configured to hold a first chemical (e.g., Sodium Bicarbonate) and lower storage cup “B” 19, 1400 is configured to hold a second chemical, (e.g., Aluminum Sulfate). Separator 21 isolates the first chemical, Sodium Bicarbonate, in the upper storage cup “A” 17 away from the second chemical, Aluminum Sulfate, in the lower storage cup “B” 19 until such time as the user decides to mix the two chemicals via a mechanical action (e.g., mechanically twisting the two cups together). The device designer must then provide a cover for upper storage cup “A” 19 and a lid for lower storage cup “B” 19.

[0069] At step 608, the device designer must design an ultrasonic vibration atomizer 110 that is configured and arranged to generate a vapor cloud of atomized carbon dioxide (CO.sub.2) by spraying droplets of atomized water onto the combined mixture of Sodium Bicarbonate and Aluminum Sulfate. A preferred parts list to construct such an ultrasonic vibration atomizer 110 is shown below in Table I and further reproduced in FIG. 2, which is an exploded view of one embodiment of an ultrasonic vibration atomizer 110 comprised of the following parts.

In Operation

[0070] In operation, the ultrasonic vibration atomizer 110 turns water into water vapor (e.g., a water vapor cloud) which then enters nozzle 2 and travels through connection silicone tube 29 terminating in storage cup “B” 19, 1400 to be sprayed onto the mixture of sodium bicarbonate and aluminum sulfate. The mixture of the atomized water vapor with the 2 chemical ingredients (Sodium Bicarbonate and Aluminum Sulfate) react to create the atomized vapor cloud of carbon dioxide (CO.sub.2) which is dispersed out of storage cup “B” 19 via exhaust 19.

[0071] As the 3 materials are mixed, 6 carbon dioxides are generated:

Al.sub.2(SO.sub.4).sub.3+6NaHCO.sub.3_>3NA.sub.2SO.sub.4+2AI(OH)3+6CO.sub.2

[0072] The mixture of the chemicals and the water are controlled by a timing circuit board 106 of the ultrasonic vibration atomizer 110. The timing circuit board 106 is pre-programmed to control the overall timing of the device including: [0073] The timing associated with creating the atomized vapor cloud of carbon dioxide CO.sub.2) approximately once every 24 hours for a duration of about 10-30 seconds which outputs about 1-3 ml of atomized (CO.sub.2) gas each 24-hour period. [0074] The timing associated with spraying the atomized water into the combustion chamber (Storage Cup “B” 19) once every 6 hours such that 4 spray periods occur in a single 24-hour cycle.

[0075] The device 100 generates a consistent level of about 2000 parts per million (ppm) of atomized (CO.sub.2) in accordance with the timing requirements described above.

[0076] Having thus described several aspects of at least one example, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art, without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the claims are not to be limited to the specific examples depicted herein. For example, the features of one example disclosed above can be used with the features of another example.
