Description

Technical Field

[0001] This invention relates to the field of mosquito trapping technology, and more particularly to a mosquito trapping device powered by solar energy. Background Technology

[0002] Mosquito-killing devices include traditional electric shock and sticky trap mosquito lamps, which generally rely on mains power and suffer from limited deployment and high energy consumption. While solar-powered mosquito killers utilize clean energy, current technologies mostly combine photovoltaic power supply with conventional trapping methods in a simple way. They are insufficient in terms of continuous trapping ability on cloudy or rainy days or at night, automatic cleaning of insect carcasses, and adaptability to humid environments, resulting in a need to improve overall mosquito-killing efficiency and ease of use.

[0003] The existing technology has the following drawbacks: Limited environmental adaptability: Existing devices only support simple solar energy systems that work on sunny days. These simple solar energy systems lack efficient energy storage and energy management. Once there are consecutive cloudy or rainy days or nighttime, the devices will fail due to insufficient power. This results in a vacuum period in mosquito control in terms of time and space, making it impossible to achieve continuous and effective killing around the clock and in all locations. In particular, the control effect is greatly reduced during dusk and night when mosquitoes are most active.

[0004] Frequent maintenance and reduced efficiency in humid environments: Existing devices generally focus on attracting and killing insects rather than cleaning them, and lack adaptive mechanisms to cope with high humidity environments. Most devices only complete the attraction and killing, with insect carcasses accumulating on the electric grid or sticky plates, requiring frequent manual cleaning. At the same time, their mechanical structures are easily blocked by insect carcasses in humid environments. This not only greatly increases maintenance costs and workload, but also, during the rainy season or in high humidity environments, blockages can lead to poor airflow, a sharp drop in attracting and killing efficiency, or even complete shutdown, failing to meet the continuous control needs under severe weather conditions. Summary of the Invention

[0005] Given the limitations of existing technologies in terms of environmental adaptability, frequent maintenance, and reduced efficiency in humid environments, a mosquito trapping device powered by solar energy is proposed.

[0006] This application provides a solar-powered mosquito trapping device, the purpose of which is to overcome the dependence on weather and maintenance problems of existing technologies by integrating a high-efficiency solar power supply system, a two-stage trapping structure based on airflow, a liftable cone-shaped insect carcass cleaning hood, and an active drying component that uses phase change materials for heat storage. This achieves continuous and efficient trapping in all weather conditions and with full automation, significantly reduces the frequency of manual cleaning, and improves the reliability and mosquito killing efficiency of the device in humid and other harsh environments.

[0007] The technical solution of the present invention is as follows: a mosquito trapping device based on solar energy, comprising a pole, a control box fixedly installed on the top of the pole, a solar panel and a mounting base, a heat-conducting cage installed between the solar panel and the mounting base, and an ultraviolet trapping mechanism set at the bottom of the mounting base; The ultraviolet trapping mechanism includes a cage-type lamp holder installed at the bottom of the mounting base. The inner wall of the cage-type lamp holder is equipped with an ultraviolet lamp for attracting mosquitoes. A temperature-conducting tube is fixedly connected inside the cage-type lamp holder. The top of the temperature-conducting tube is threadedly connected to the bottom of the temperature-conducting cage. An insulation box is fixedly connected to the bottom of the temperature-conducting tube. A conical cover is slidably connected to the outer wall of the insulation box. The ultraviolet trapping mechanism also includes a first suction assembly disposed on the upper part of the insulated box. The first suction assembly includes a rotatable first rotating tube, a plurality of actuating plates are fixedly connected to the outer wall of the first rotating tube, and a plurality of first fan blades are located above the actuating plates. The conical cover can slide up and down along the outer wall of the insulated box to change the distance between its outer wall and the actuating plates.

[0008] Using the above scheme, the ultraviolet lamp is responsible for optically attracting mosquitoes through the ultraviolet trapping mechanism. The first blade generates a downward airflow, which sucks in the mosquitoes and adsorbs them onto the surface of the conical cover. During the day, solar energy stores heat in the phase change material of the insulated box through the heat conduction cage and heat conduction pipe. At night, the heat is released to bake the conical cover, accelerating the dehydration and death of mosquitoes. The conical cover can slide along the outer wall of the insulated box. In rainy weather, the humidity sensing mechanism pushes the conical cover upward, reducing the distance between it and the actuating plate, so that the actuating plate changes from scraping to slapping mode, effectively cleaning up the damp insect carcasses. This realizes the full automation of the process from trapping and killing to cleaning, and adapts to different weather conditions to maintain effectiveness.

[0009] Furthermore, when the conical cover is in the lower position, there is a first gap between its outer wall and the actuating plate. The actuating plate is used to scrape away mosquitoes on the outer wall of the conical cover. When the conical cover slides upward to the upper position, a second gap smaller than the first gap is formed between its outer wall and the actuating plate. The actuating plate is used to agitate the outer wall of the conical cover.

[0010] By adopting the above scheme, the position of the conical cover is driven by the ambient humidity through the setting of the conical cover and the toggle plate. The position of the conical cover determines the working mode of the toggle plate. Ultimately, they jointly realize adaptive cleaning from dry scraping to wet tapping, ensuring the continuous and efficient operation of the device under different climatic conditions.

[0011] Furthermore, a bucket-shaped base is fixedly connected to the bottom of the cage-type lamp holder, and an insect carcass collection box is installed on the inner wall of the bucket-shaped base. A grid bottom plate is installed at the bottom of the insect carcass collection box, and multiple ventilation holes with a diameter smaller than that of mosquitoes are opened at the bottom of the insect carcass collection box.

[0012] Furthermore, an expanding sponge is provided on the top of the grid bottom plate, and a lifting plate is connected to the top of the expanding sponge. A telescopic spring is fixedly connected between the top of the lifting plate and the inner wall of the insect corpse collection box. Multiple top rods are fixedly connected to the top of the lifting plate, and the tops of the multiple top rods abut against the bottom of the conical cover. When the expanding sponge absorbs water and expands, it pushes the lifting plate upward to overcome the elastic force of the telescopic spring and rises. The lifting plate drives the conical cover to slide upward through the top rods.

[0013] Using the above scheme, the insect carcass collection box, in a dry environment, causes the expanding sponge to shrink in volume. Under the tension of the telescopic spring, the lifting plate and top rods are in a low position, maintaining the conical cover in the default lower position. When entering a humid environment, the expanding sponge absorbs water and expands rapidly, generating a strong upward pushing force. This force overcomes the elasticity of the telescopic spring, pushing the lifting plate upward. The rise of the lifting plate directly drives the multiple top rods fixed to it to move upward synchronously. The top of the top rods then pushes against the bottom of the conical cover, driving the conical cover to slide upward along the outer wall of the insulation box to the preset upper position, thereby triggering the cleaning mode switch. This achieves automatic and direct control of humidity on the position of the core extermination components.

[0014] Furthermore, multiple heat-conducting fins are fixedly connected to the inner wall of the heat-conducting pipe and the heat-insulating box. The multiple heat-conducting fins are circumferentially distributed inside the heat-conducting pipe and the heat-insulating box. A heat storage cavity is opened in the inner wall of the heat-insulating box. The heat storage cavity is filled with phase change material. The heat storage cavity is arranged around the inner wall area of ​​the heat-insulating box corresponding to the conical cover.

[0015] Using the above scheme, during the day, sunlight heats the heat-conducting cage through the heat-conducting pipes. The heat is conducted downwards through the pipes, and the heat-conducting fins efficiently dissipate the heat from the pipe walls into the air inside the insulated box, forming a small hot air circulation that accelerates the downward flow of heat. The heat eventually converges in the heat storage chamber area of ​​the insulated box. The phase change material filled in the heat storage chamber absorbs this heat and melts, storing the thermal energy in the form of latent heat. At night, as the ambient temperature drops, the phase change material in the heat storage chamber begins to solidify, releasing the stored latent heat. This heat is directly conducted through the metal walls of the insulated box to the conical cover on the outer wall, maintaining its surface temperature at a high level. Mosquitoes adhering to the surface of the conical cover are thus continuously baked, accelerating dehydration and death, greatly improving the extermination efficiency.

[0016] Furthermore, a first gear ring is fixedly connected to the lower outer wall of the first rotating tube, and a first motor is fixedly connected to the inner wall of the insulation box. The output shaft of the first motor is sleeved with a first drive gear, and the first drive gear meshes with the first gear ring.

[0017] Using the above scheme, the output shaft of the first motor drives the first drive gear to rotate. The rotating first drive gear acts through the first gear ring meshing with it, directly driving the entire first rotating tube to rotate around its axis. In this way, the first fan blade and the actuating plate fixed on the outer wall of the first rotating tube also rotate synchronously, respectively performing the functions of generating suction airflow and scraping and disturbing the insect carcasses on the surface of the conical cover.

[0018] Furthermore, a second suction assembly is provided below the first rotating tube. The second suction assembly includes a second rotating tube rotatably connected to the inner wall of the insulation box. A plurality of second fan blades are fixedly connected to the lower outer wall of the second rotating tube, and the second fan blades are located below the insulation box.

[0019] Furthermore, a second gear ring is fixedly connected to the upper outer wall of the second rotating tube, and a second motor is fixedly connected to the inner wall of the insulation box. The output shaft of the second motor is sleeved with a second drive gear, and the second drive gear meshes with the second gear ring.

[0020] By adopting the above scheme, the second suction component, together with the downward main suction force generated by the first fan blade in the first suction component above, forms a two-stage relay effect, ensuring that the insect carcasses scraped off the surface of the conical cover by the agitator or carried down by the airflow can be continuously and powerfully sucked downwards. This effectively overcomes the attenuation at the end of the airflow and thoroughly blows them into the insect carcass collection box in the bucket-shaped base, significantly improving the reliability and efficiency of the final collection and preventing insect carcasses from lingering in the lower part of the device.

[0021] Furthermore, the top of the insect carcass collection box is provided with an air guide cover, which is located below the insulated box, and the top rod passes through the air guide cover.

[0022] By adopting the above scheme, the airflow from above is guided and gathered by the set air guide cover, so that it enters the collection box more smoothly and centrally, improving the efficiency of insect carcasses entering the box. At the same time, it acts as a physical baffle to prevent falling insect carcasses from splashing out of the collection area under the disturbance of airflow, ensuring the reliability of collection, and providing a vertical movement channel and guide for the push rod, ensuring that the push rod remains stable when moving up and down and accurately transmitting the pushing force.

[0023] The beneficial effects of this invention are: The system, consisting of a humidity sensing mechanism, a liftable conical hood, and a first rotating tube with a deflector plate, can automatically switch cleaning modes according to the humidity of the environment. In dry conditions, the conical hood is in a low position, and the deflector plate effectively scrapes away the dry insect carcasses on its surface at a larger interval. When the ambient humidity increases, the expanding sponge absorbs water and expands, precisely driving the conical hood upward through the top rod. This causes the deflector plate to switch to high-frequency beating and agitation of the hood surface at a smaller interval, thereby efficiently peeling off the damp and sticky insect carcasses. This significantly reduces the frequency and cost of manual cleaning and effectively prevents the device's performance from declining due to insect carcass adhesion and blockage. It effectively solves the problems of frequent maintenance and sudden performance drop in humid environments in existing technologies.

[0024] Through a heat storage and conduction path consisting of a heat-conducting cage, heat-conducting pipe, an insulated box with built-in heat-conducting fins, and a heat storage cavity filled with phase change material, solar thermal energy can be actively collected and stored. The heat absorbed during the day is stored in the phase change material and released at night or during low-temperature periods to continuously heat the surface of the conical cover. This not only accelerates the dehydration and death process of the adsorbed mosquitoes and improves the instantaneous killing efficiency, but also pre-dries the insect carcasses, making them brittle and easy to detach. This fundamentally enhances the reliability of the cleaning system and synergistically improves the device's continuous operation capability in humid and other harsh environments.

[0025] By deeply integrating photoelectric conversion, photothermal collection, thermal energy storage, and the functions of attracting, killing, and cleaning, the system achieves the synergistic utilization of the multiple effects of solar energy—light, electricity, and heat. The electricity generated by the solar panels drives the core functional components, while the associated waste heat is actively collected and converted into a storable and readily available heat source for mosquito control. This combined heat and power (CHP) energy utilization model significantly improves the overall utilization efficiency of solar energy per unit, reduces dependence on a single energy storage unit, and thus significantly enhances the device's energy self-sufficiency and long-term operational autonomy in environments without stable mains power, providing a solid energy foundation for continuous and efficient mosquito control in all weather conditions and regions.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 - Figure 11 A mosquito trapping device powered by solar energy is provided, including a pole 1, a control box 2 fixedly installed on the top of the pole 1, a solar panel 3 and a mounting base 5, a heat-conducting cage 4 installed between the solar panel 3 and the mounting base 5, and an ultraviolet trapping mechanism 6 set at the bottom of the mounting base 5.

[0030] Reference Figure 3 - Figure 8The ultraviolet (UV) trapping mechanism 6 includes a cage-type lamp holder 62 installed at the bottom of the mounting base 5. The inner wall of the cage-type lamp holder 62 is provided with UV lamps 63 for attracting mosquitoes. A heat-conducting pipe 61 is fixedly connected inside the cage-type lamp holder 62. The top of the heat-conducting pipe 61 is threadedly connected to the bottom of the heat-conducting cage 4. An insulation box 612 is fixedly connected to the bottom of the heat-conducting pipe 61. A conical cover 66 is slidably connected to the outer wall of the insulation box 612. The UV trapping mechanism 6 also includes a first suction assembly 65 disposed on the upper part of the insulation box 612. The first suction assembly 65 includes a rotatable first rotating pipe 651. A plurality of actuating plates 653 are fixedly connected to the outer wall of the first rotating pipe 651, and a plurality of first fan blades 652 located above the actuating plates 653. The conical cover 66 can slide up and down along the outer wall of the insulation box 612 to change the distance between its outer wall and the actuating plates 653.

[0031] Specifically, the cage-like lamp holder 62 serves as the external load-bearing frame and main trapping area of ​​the entire device. Its mesh structure ensures internal ventilation and light transmission while preventing larger foreign objects from entering. The ultraviolet lamp 63 acts as the bait, emitting specific wavelengths of ultraviolet light that are highly attractive to mosquitoes, drawing them to the vicinity of the device. The conical hood 66, fitted onto the outer wall of the insulated box 612 and capable of sliding up and down, serves as the adsorbed surface and dynamic cleaning structure. Its conical design facilitates airflow guidance and the collection of insect carcasses. The heat-conducting cage 4 absorbs sunlight during the day. The temperature rise is the main source of heat; the heat conduction pipe 61 is the heat transfer channel, which quickly transports the heat collected during the day downwards; the heat preservation box 612 and its heat storage chamber 613 are located at the bottom of the heat conduction pipe 61, and are filled with phase change material. They absorb and store heat during the day and release heat at night, providing a continuous baking heat source for the conical cover 66; the toggle plate 653 rotates with the first rotating tube 651, and its main function is to scrape and clean the mosquito corpses attached to the outer wall of the conical cover 66. The distance between the plate and the conical cover 66 is adjustable to achieve different cleaning modes.

[0032] The ultraviolet-based trapping mechanism 6 and the ultraviolet lamp 63 optically attract mosquitoes. The first fan blade 652 generates a downward airflow, which draws in mosquitoes and attaches them to the surface of the conical cover 66. During the day, solar energy stores heat in the phase change material of the insulated box 612 through the heat-conducting cage 4 and the heat-conducting pipe 61. At night, the heat is released to bake the conical cover 66, accelerating the dehydration and death of mosquitoes. The conical cover 66 can slide along the outer wall of the insulated box 612. In rainy weather, the humidity sensing mechanism pushes the conical cover 66 upward, reducing the distance between it and the actuating plate 653, so that the actuating plate 653 changes from scraping to slapping mode, effectively cleaning up the damp insect carcasses. This realizes the full automation of the process from trapping and killing to cleaning, and adapts to different weather conditions to maintain efficiency.

[0033] Reference Figure 5 - Figure 8When the conical cover 66 is in the lower position, there is a first gap between its outer wall and the agitator 653. The agitator 653 is used to scrape off mosquitoes on the outer wall of the conical cover 66. When the conical cover 66 slides upward to the upper position, a second gap smaller than the first gap is formed between its outer wall and the agitator 653. The agitator 653 is used to agitate the outer wall of the conical cover 66.

[0034] With the help of the conical cover 66 and the actuating plate 653, the position of the conical cover 66 is changed by the ambient humidity. The position of the conical cover 66 determines the working mode of the actuating plate 653. Together, they achieve adaptive cleaning from dry scraping to wet tapping, ensuring the continuous and efficient operation of the device under different climatic conditions.

[0035] Reference Figure 5 - Figure 11 The bottom of the cage-type lamp holder 62 is fixedly connected to a bucket-type base 64. An insect corpse collection box 68 is installed on the inner wall of the bucket-type base 64. A grid bottom plate 686 is installed at the bottom of the insect corpse collection box 68, and multiple ventilation holes with a diameter smaller than that of mosquitoes are opened at the bottom of the insect corpse collection box 68. An expanding sponge 685 is set on the top of the grid bottom plate 686. A lifting plate 683 is connected to the top of the expanding sponge 685. A telescopic spring 682 is fixedly connected between the top of the lifting plate 683 and the inner wall of the insect corpse collection box 68. Multiple push rods 684 are fixedly connected to the top of the lifting plate 683. The tops of the multiple push rods 684 abut against the bottom of the conical cover 66. When the expanding sponge 685 absorbs water and expands, it pushes the lifting plate 683 upward to overcome the elastic force of the telescopic spring 682 and rises. The lifting plate 683 drives the conical cover 66 to slide upward through the push rods 684.

[0036] Specifically, the insect corpse collection box 68 is the final collection container and airflow channel for insect corpses, and the ventilation holes ensure air circulation; the volume of the expanding sponge 685 changes with the ambient humidity, converting the humidity signal into mechanical expansion force; the lifting plate 683 integrates and transmits the pushing force of the expanding sponge 685 upward; the top rod 684 transmits the vertical displacement of the lifting plate 683 to the conical cover 66, which is the structure connecting the lower sensing mechanism and the upper execution component.

[0037] In a dry environment, the expanding sponge 685 shrinks in volume through the insect carcass collection box 68. Under the tension of the telescopic spring 682, the lifting plate 683 and the top rod 684 are in a low position, maintaining the conical cover 66 in the default lower position. When entering a humid environment, the expanding sponge 685 absorbs water and expands rapidly, generating a strong upward pushing force. This force overcomes the elasticity of the telescopic spring 682, pushing the lifting plate 683 upward. The rise of the lifting plate 683 directly drives the multiple top rods 684 fixed to it to move upward synchronously. The top of the top rods 684 then pushes the bottom of the conical cover 66, driving the conical cover 66 to slide upward along the outer wall of the insulation box 612 to the preset upper position, thereby triggering the cleaning mode switch. This achieves automatic and direct control of humidity on the position of the core extermination component.

[0038] Reference Figure 4 - Figure 7 Multiple heat-conducting fins 611 are fixedly connected to the inner walls of the heat-conducting pipe 61 and the heat-insulating box 612. The multiple heat-conducting fins 611 are circumferentially distributed inside the heat-conducting pipe 61 and the heat-insulating box 612. A heat storage cavity 613 is opened in the inner wall of the heat-insulating box 612. The heat storage cavity 613 is filled with phase change material. The heat storage cavity 613 is arranged around the inner wall area of ​​the heat-insulating box 612 corresponding to the conical cover 66.

[0039] Specifically, the heat-conducting fins 611 increase the contact area between the heat-conducting pipe 61 and the inner wall of the insulation box 612 and the internal air or medium, so that the heat from the heat-conducting cage 4 is introduced into the internal space of the insulation box 612 more quickly and evenly, and finally guided to the heat storage cavity 613; the phase change material is filled in the heat storage cavity 613 as a medium for storing and releasing heat energy, converting instantaneous solar energy into a continuously usable heat source.

[0040] During the day, sunlight heats the heat-conducting cage 4 via the heat-conducting pipe 61. The heat is conducted downwards through the heat-conducting pipe 61, and the heat-conducting fins 611 efficiently dissipate the heat from the pipe wall into the air inside the heat-insulating box 612, forming a small hot air circulation that accelerates the downward flow of heat. The heat eventually converges in the heat storage cavity 613 area of ​​the heat-insulating box 612. The phase change material filled in the heat storage cavity 613 absorbs this heat and melts, storing the thermal energy in the form of latent heat. At night, as the ambient temperature drops, the phase change material in the heat storage cavity 613 begins to solidify, releasing the stored latent heat. This heat is directly conducted through the metal box wall of the heat-insulating box 612 to the conical cover 66 on the outer wall, maintaining its surface temperature at a high level. Mosquitoes adsorbed on the surface of the conical cover 66 are thus continuously baked, accelerating dehydration and death, greatly improving the killing efficiency.

[0041] Reference Figure 8A first gear ring 654 is fixedly connected to the lower outer wall of the first rotating tube 651, and a first motor 656 is fixedly connected to the inner wall of the heat preservation box 612. The output shaft of the first motor 656 is sleeved with a first drive gear 655, which meshes with the first gear ring 654.

[0042] The first motor 656, through its output shaft, drives the first drive gear 655 to rotate. The rotating first drive gear 655, through the first gear ring 654 meshing with it, directly drives the entire first rotating tube 651 to rotate around its axis. Thus, the first fan blade 652 and the actuating plate 653, fixed to the outer wall of the first rotating tube 651, also rotate synchronously, respectively performing the functions of generating suction airflow and scraping and disturbing the insect carcasses on the surface of the conical cover 66.

[0043] Reference Figure 5 - Figure 8 A second suction assembly 67 is provided below the first rotating pipe 651. The second suction assembly 67 includes a second rotating pipe 671 rotatably connected to the inner wall of the insulation box 612. A plurality of second fan blades 672 are fixedly connected to the lower outer wall of the second rotating pipe 671, and the second fan blades 672 are located below the insulation box 612. A second gear ring 673 is fixedly connected to the upper outer wall of the second rotating pipe 671. A second motor 675 is fixedly connected to the inner wall of the insulation box 612. A second drive gear 674 is sleeved on the output shaft of the second motor 675, and the second drive gear 674 meshes with the second gear ring 673.

[0044] The second suction component 67, together with the downward main suction force generated by the first fan blade 652 in the first suction component 65 above, forms a two-stage relay effect, ensuring that the insect carcasses scraped off the surface of the conical cover 66 by the agitator plate 653 or carried down by the airflow can be continuously and powerfully sucked downwards, effectively overcoming the attenuation at the end of the airflow and thoroughly blowing them into the insect carcass collection box 68 in the bucket-shaped base 64, significantly improving the reliability and efficiency of the final collection and preventing insect carcasses from lingering in the lower part of the device.

[0045] Reference Figure 9 - Figure 11 The top of the insect carcass collection box 68 is provided with an air guide cover 681, which is located below the heat preservation box 612, and the top rod 684 passes through the air guide cover 681.

[0046] The air guide cover 681 guides and gathers the airflow from above, allowing it to enter the collection box more smoothly and centrally, thus improving the efficiency of insect carcasses entering the box. At the same time, it acts as a physical baffle to prevent falling insect carcasses from splashing out of the collection area due to airflow disturbance, ensuring the reliability of collection. It also provides a vertical movement channel and guide for the push rod 684, ensuring that the push rod 684 remains stable during up and down movement and accurately transmits the pushing force.

[0047] Working principle of the invention: During operation, the ultraviolet trapping mechanism 6 is installed as a whole. The cage-type lamp holder 62 in this mechanism is installed at the bottom of the mounting base 5. Multiple ultraviolet lamps 63 are arranged around its inner wall. The heat-conducting pipe 61 fixedly connected inside the cage-type lamp holder 62 forms a heat transfer channel. Its top is threaded to the bottom of the heat-conducting cage 4, and its bottom is fixedly connected to an insulation box 612. A cone-shaped cover 66 that can slide up and down is fitted on the outer wall of the insulation box 612, forming a key insect collection and cleaning structure.

[0048] When working at night, the light emitted by the ultraviolet lamp 63 acts as the main bait, attracting mosquitoes to the area of ​​the cage-like lamp holder 62. At the same time, the first suction assembly 65 starts to work, and the multiple first fan blades 652 fixed on the outer wall of the first rotating tube 651 rotate accordingly, generating a downward airflow. This airflow passes through the grid of the cage-like lamp holder 62 and quickly sucks the mosquitoes attracted by the ultraviolet light into the device. The mosquitoes move downward with the airflow and are eventually adsorbed on the outer wall surface of the lower conical cover 66, completing the initial capture.

[0049] To further ensure capture efficiency and handle the detached mosquitoes, a second suction assembly 67 is installed below the first rotating tube 651. When the second fan blade 672 rotates, it generates additional downward suction, forming a dual-stage suction effect with the first fan blade 652 above. This downward airflow not only enhances the overall suction capacity, ensuring that mosquitoes or insect carcasses are effectively collected and preventing escape, but also ensures that the insects are collected. Subsequently, the mosquito carcasses that are sucked in and eventually die fall into the bucket-shaped base 64 fixedly connected to the bottom of the cage-type lamp holder 62 under the guidance of the airflow. A detachable insect carcass collection box 68 is installed on the inner wall of the bucket-shaped base 64 for collecting insect carcasses. The bottom of the insect carcass collection box 68 has multiple ventilation holes with a diameter smaller than that of mosquitoes, ensuring smooth airflow while ensuring that the insect carcasses are intercepted inside the box.

[0050] During sunny days, the device switches to energy harvesting and active extermination mode. Solar panel 3 converts solar energy into electrical energy, which is stored in a battery within control box 2 to power nighttime operation. Simultaneously, sunlight significantly raises the temperature of the heat-conducting cage 4. This heat is conducted downwards through heat-conducting pipe 61 and directed into the heat storage cavity 613 located on the inner wall of the insulated box 612. The phase change material inside absorbs a large amount of heat during the day and melts, storing the thermal energy. At night, when the temperature drops, the phase change material solidifies and releases the stored heat, continuously heating the insulated box 612 and its outer conical cover 66. This traps mosquitoes adsorbed on the surface of the conical cover 66 with airflow and subjectes them to continuous heating, accelerating their dehydration and death process, thus improving extermination efficiency.

[0051] In rainy or high-humidity environments, the expanding sponge 685 expands after absorbing water, generating an upward pushing force. This force pushes the lifting plate 683 to overcome the elastic force of the telescopic spring 682 and move upward. The rise of the lifting plate 683 directly drives the conical cover 66 to slide upward along the outer wall of the insulation box 612 through the top rod 684. The change in the position of the conical cover 66 directly adjusts the distance between its outer wall and the actuating plate 653 fixed on the first rotating tube 651.

[0052] Under normal conditions, the conical cover 66 is in the lower position, with a relatively large initial gap between its outer wall and the agitator plate 653. At this time, the agitator plate 653 mainly serves to scrape away the dead insects from the cover wall. When the conical cover 66 is raised, the gap narrows to a second gap, allowing the agitator plate 653 to agitate and beat the outer wall of the conical cover 66 at a closer distance. This more effectively shakes off and cleans up any dead or live insects that may have adhered to the cover wall due to moisture, preventing accumulation and blockage, and ensuring that the device can still operate efficiently in inclement weather.

[0053] The device is powered by two independent motor systems. The first motor 656 drives the entire first rotating tube 651, along with its first fan blade 652 and actuating plate 653, to rotate. Similarly, the second motor 675 drives the second fan blade 672 to rotate. When insect carcasses need to be cleaned, maintenance personnel can open the bucket-shaped base 64 and remove the entire insect carcass collection box 68 for emptying and cleaning. The air guide cover 681 on top of the insect carcass collection box 68 is located below the insulation box 612, guiding airflow and preventing insect carcasses from splashing. The top rod 684 passes through holes in the air guide cover 681 and interacts with the conical cover 66 above. The entire maintenance process is simple, ensuring the long-term stable use of the device.
