Description

Technical Field

[0001] This invention relates to the technical field of insect trapping, and in particular to a passive midge trap device. Background Technology

[0002] The most mainstream mosquito traps on the market today that are suitable for home use are mostly "photocatalytic suction" mosquito traps that combine multiple principles. They use UV light to irradiate a photocatalyst to simulate biological respiration, decomposing organic matter in the air to produce trace amounts of carbon dioxide and water vapor, intending to attract mosquitoes. Combining this with the phototaxis of some nocturnal mosquitoes and their habit of flying with air currents, a built-in high-speed fan generates airflow to suck the mosquitoes into the trap chamber, where they are killed by drying or electric shock.

[0003] For example, Chinese patent CN203723307U discloses a dual-trapping mosquito killer, which targets mosquitoes' sensitivity to human odor and their attraction to darkness (particularly sensitive to light in the 360-400nm range), designing a dual-trapping and purely physical killing mechanism. Specifically, long-distance attraction: the attractant generator 3 produces a human-like odor to lure mosquitoes from a distance to the killer, unaffected by obstacles. Short-distance attraction: when mosquitoes approach the killer at a certain distance, the black light (360-400nm) produced by the UV lamp 6 strongly attracts them closer to the light source. Killing: when mosquitoes approach the light source, they are quickly sucked into the mosquito storage box 1 of the killer by the fan 2, where they are dried and killed.

[0004] However, this design is also very limited in its effectiveness against agile and uniquely habitual midges. First, the carbon dioxide concentration produced by the photocatalyst is extremely low, making it difficult to form an effective attraction gradient in open or ventilated environments. Second, midges are diurnal insects, and the weak ultraviolet light from the mosquito-catching lamp has no attraction under sunlight. Finally, their small size and susceptibility to airflow mean they may not actively approach the trap's effective adsorption range, resulting in an overall very low capture success rate.

[0005] While commercially available mosquito traps are commonly used to control midges, their design principles and operational methods have specific drawbacks that become more apparent when their primary target is catching these insects. Firstly, in terms of trapping effectiveness, these devices rely heavily on the ultraviolet spectrum to attract insects. However, midges are most active during the day when there is ample light, making the ultraviolet light trapping principle, primarily designed for nighttime use, less effective. Furthermore, the quantum efficiency of their core 365nm ultraviolet LED lamp decays over time, leading to a gradual decrease in light intensity and further weakening their long-term trapping ability. Therefore, it is necessary to provide a passive midge trap device that is simple in structure, requires no external power source, and utilizes natural biological cycles to not only capture adult midges but also directly disrupt their reproductive chain at the source of high-density midge populations, achieving long-term and environmentally friendly effective control. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a passive midge trap device with a simple structure and no need for external power supply. Utilizing the natural biological cycle principle, it can not only capture adult midges, but also directly block their reproductive chain at the source of high-density midge breeding, thus achieving long-term and environmentally friendly effective control.

[0007] The technical solution adopted by this utility model is as follows: This utility model includes a trap body, the lower end of which is provided with a base, the base serving as an algae cultivation area, the algae cultivation area containing water and blue-green algae culture solution, the upper end of which is provided with a trapping funnel, the lower edge of which narrows inward and extends into the inner cavity of the trap body, and the opening of the trapping funnel facing the algae cultivation area.

[0008] As can be seen from the above scheme, this application utilizes cyanobacteria to attract midges to reproduce and lay eggs, and in the process, uses the midge eggs as food, thereby disrupting their reproductive chain. To further enhance the growth rate of cyanobacteria, this application presents a novel trap that requires no electricity, deeply integrates with the biological habits of midges, and possesses midge-specific characteristics. It efficiently traps midges by simulating their natural breeding grounds. This device can operate autonomously without an external power source. Utilizing the principle of natural biological cycles, it can not only capture adult midges but also directly disrupt their reproductive chain at high-density midge breeding grounds, thereby achieving long-term and environmentally friendly effective control.

[0009] Midges enter the trap through the trapping funnel. Their flying ability is insufficient to overcome the steep angle of the funnel and escape via the original route. They are ultimately trapped inside the device until they die, thus achieving effective physical capture of adult midges. These trapped and dead adults eventually fall into the algae cultivation area below.

[0010] Rapidly multiplying cyanobacteria release specific volatile organic compounds (VOCs) into the surrounding environment during their metabolism, increasing local humidity within the device. Cyanobacteria serve as oviposition habitats for female midges, and these chemical and physical signals act as a strong attractant, mimicking their natural oviposition environment. Eggs laid by the female midges or hatched larvae fall into water rich in cyanobacteria. The algae directly consume and decompose these high-protein eggs and larvae as a source of nutrition, thus disrupting the midge reproductive chain at its source. Furthermore, the trapping funnel effectively traps adult midges physically.

[0011] In a preferred embodiment, the upper end of the trapping funnel is provided with a ventilation hood, which is a hollow cylindrical structure. The side wall of the ventilation hood is provided with several sets of vertically arranged ventilation openings at equal intervals, and the bottom edge of the ventilation hood contacts the inner wall of the trapping funnel.

[0012] In a preferred embodiment, the upper end of the ventilation hood is provided with a top cover, and the inner side of the top cover is provided with a mounting groove. The mounting groove is a ring structure, and a quantum dot film is installed in the mounting groove. The quantum dot film is located above the opening of the trapping funnel.

[0013] A preferred embodiment is that the inner wall of the trapping funnel forms an angle of 40 degrees with the vertical direction.

[0014] A preferred embodiment is that the base is in the shape of a wide-mouthed basin with its edges turned upwards.

[0015] A preferred embodiment is that the side wall of the base has several drainage outlets.

[0016] A preferred embodiment is characterized in that the trap body has a hollow cylindrical structure. Attached Figure Description

Detailed Implementation

[0018] like Figures 1 to 4As shown, in this embodiment, the present invention includes a trap body 1, a base 2 at the lower end of the trap body 1, the base 2 serving as an algae cultivation area, the algae cultivation area containing water and cyanobacteria culture solution, and a trapping funnel 3 at the upper end of the trap body 1, the lower edge of the trapping funnel 3 narrowing inward and extending into the inner cavity of the trap body 1, the opening of the trapping funnel 3 facing the algae cultivation area.

[0019] The trapping funnel 3 is a ring-shaped funnel-like component designed to guide midges flying downwards and increase the difficulty for them to fly upwards. Rapidly multiplying cyanobacteria release specific volatile organic compounds (VOCs) into the surrounding environment during metabolism, increasing the local humidity inside the device. Since cyanobacteria are the spawning grounds of female midges, these chemical and physical signals constitute a strong attractant for them, mimicking their natural spawning environment. Attracted female midges, following the scent and humidity sources, enter the device through the trapping funnel 3. Guided by the structure of the trapping funnel 3, they fly downwards towards the water surface of the algae cultivation area to lay their eggs, ultimately becoming trapped inside the device until they die, thus achieving effective physical capture of adult midges. These trapped adults eventually fall into the algae cultivation area below.

[0020] When the eggs laid by female midges or the larvae that hatch fall into water bodies rich in cyanobacteria, the algae will directly consume and decompose these high-protein eggs and larvae as a source of nutrition, thus interrupting the midge's reproductive chain at its source. In addition, the design of the trapping funnel 3 also plays an effective role in physically trapping adult midges.

[0021] like Figures 1 to 4 As shown, in this embodiment, a ventilation hood 4 is provided at the upper end of the trapping funnel 3. The ventilation hood 4 has a hollow cylindrical structure, and several sets of vertically arranged ventilation openings 5 ​​are equidistantly opened on the side wall of the ventilation hood 4. The bottom edge of the ventilation hood 4 contacts the inner wall of the trapping funnel 3. The ventilation openings 5 ​​are channels for the target midges to enter the device. The use of multiple sets of ventilation openings 5 ​​facilitates the entry of the target midges into the device.

[0022] like Figures 1 to 4 As shown, in this embodiment, the upper end of the ventilation hood 4 is provided with a top cover 6, and the inner side of the top cover 6 is provided with an installation groove 7. The installation groove 7 is a ring structure, and a quantum dot film is installed in the installation groove 7. The quantum dot film is located above the opening of the trapping funnel 3.

[0023] This application introduces quantum dot technology to promote the photosynthesis of cyanobacteria by converting light wavelengths, thereby accelerating their growth. The quantum dot film is a flexible, semi-transparent sheet containing a specific type of quantum dot material. The quantum dot film is fixed to the top of the top cover 6 via the mounting groove 7. Quantum dots can absorb ambient light and emit light of a specific wavelength that is more suitable for the photosynthesis of cyanobacteria.

[0024] In this embodiment, the angle between the inner wall of the trapping funnel 3 and the vertical direction is 40 degrees. Studies have shown that the upward flight angle of Diptera insects typically does not exceed 35 degrees. The angle of 40 degrees between the inner wall of the trapping funnel 3 and the vertical direction is greater than the maximum upward flight angle of midges. Therefore, once a midge enters the trap through the vent 5, its flight ability will be insufficient to overcome the steep angle of the funnel and escape via its original path. It will ultimately be trapped inside the device until it dies, thus achieving effective physical capture of adult midges. These trapped and dead adults will eventually fall into the algae cultivation area below. After their bodies decompose in the water, they constitute abundant biomass, providing additional key nutrients such as nitrogen and phosphorus for the growth of cyanobacteria. This process creates a positive feedback loop: the more midges are captured, the more nutrients are provided to the cyanobacteria, which in turn promotes the cyanobacteria to reproduce more quickly, thereby releasing stronger attraction signals, enhancing the long-term capture efficiency of the trap, and forming a self-reinforcing, sustainable micro-ecosystem.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, the base 2 is a wide-mouthed basin with its edges turned upwards.

[0026] like Figure 2 As shown, in this embodiment, the side wall of the base 2 is provided with several drainage outlets 8. The drainage outlets 8 are used to control the maximum water level in the cultivation area, preventing overflow due to excessive water levels caused by rainfall or other reasons. Furthermore, when rainfall causes the water level to rise, the nutrient-rich culture solution will be discharged through the drainage outlets 8. If the device is placed in a green belt or garden, this overflowing natural "liquid fertilizer" can also fertilize the surrounding soil and plants, achieving ecological utilization of resources.

[0027] like Figures 1 to 4 As shown, in this embodiment, the trap body 1 has a hollow cylindrical structure.

[0028] In this embodiment, the device is placed in an environment with natural or artificial light. Light shines onto the quantum dot film on top, where the quantum dot material absorbs the light energy and converts it into light of a specific wavelength (such as red light in the 630-680 nm range). This converted light then shines downwards through the vents 5 of the top cover 6 onto the algae cultivation area, providing efficient photosynthetic energy for the cyanobacteria and thus greatly promoting their growth and reproduction.

[0029] In this embodiment, this application presents a novel green ecological midge design based on cyanobacteria technology, aimed at effectively controlling the population of midges. This mosquito trap utilizes cyanobacteria to attract midges to reproduce and lay eggs, using the midge eggs as food in the process, thereby disrupting their reproductive chain. To further enhance the growth rate of cyanobacteria, this study introduces quantum dot technology, which promotes photosynthesis by converting light wavelengths, thus accelerating their growth. Accelerating the growth rate of cyanobacteria has several advantages: First, the rapid growth of cyanobacteria can produce a large amount of biomass more quickly, thereby increasing its ability to attract midges and further enhancing the mosquito-trapping effect; second, rapid growth allows cyanobacteria to form a stable ecosystem in a short time, improving the overall efficiency and sustainability of the mosquito trap. Furthermore, the faster-growing cyanobacteria can consume nutrients in the water more quickly, inhibiting the growth of other aquatic organisms and reducing competitive pressure on the ecosystem. Moreover, this design is not limited by location, allowing the mosquito trap to be flexibly applied in various environments, from urban to suburban areas. Finally, this accelerated growth characteristic may also reduce resource waste, lower overall operating costs, and improve practicality and economic efficiency. This method has several advantages: First, it uses no chemicals, avoiding pollution to the environment and human health, truly achieving zero carbon emissions; second, by establishing a simple ecological cycle system, it can effectively control midge populations in the long term, overcoming the short-lived effects of traditional control methods; finally, the device is simple in design, easy to operate and maintain, and suitable for widespread application in various environments. In summary, this design is not only environmentally friendly but also has the potential to sustainably solve mosquito problems, possessing significant practical value and promotional significance.

[0030] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
