Description

Technical Field

[0001] This application relates to the field of pest control technology, specifically to a device and method for multimodal synergistic trapping of flying insects. Background Technology

[0002] Currently available insect trapping devices are divided into single-signal trapping models and multi-signal simple composite models. Single-signal trapping models rely on only one signal—light source, heat source, or attracting odor—to attract insects. This results in a narrow trapping range and poor adaptability to various insect species. In contrast, the few composite trapping products that incorporate light, heat, and odor structures only physically assemble the trapping components. The various trapping structures operate independently without any linkage or coordination. This not only fails to create a continuous and complete insect trapping path from far to near, but also makes it easy for the various signals to interfere with each other.

[0003] For example, the airflow generated by the built-in fan can disrupt the concentration gradient of the attracting odor, and the heat field formed by disordered heat dissipation at the top of the device can interfere with the biomimetic heat attraction effect. At the same time, most insect trapping devices on the market only use a single 365nm ultraviolet wavelength light source, which cannot match the differentiated photosensitive characteristics of flies preferring 395nm and moths attracting 455nm blue light, resulting in insufficient broad-spectrum trapping ability. Existing devices with heat attraction functions generally rely on resistance wires to actively heat and generate heat radiation, which will increase the overall power consumption of the machine by 30% to 50%, and is also prone to local high temperature and uneven temperature distribution of the machine body, posing safety hazards. Moreover, the heat radiation generated by resistance wire heating is significantly different from the temperature characteristics of human blood surface, resulting in a weak biomimetic insect attraction effect. Overall, existing products are unable to achieve synergistic effects of light signals, heat signals, and odor signals, and have multiple defects such as broken trapping paths, poor wavelength adaptation, high energy consumption, inefficient biomimetic heat attraction, irregular odor diffusion, and easy blockage of the inner cavity by insect corpses, which cannot meet the needs of efficient trapping of all types of flying insects indoors. Summary of the Invention

[0004] This application provides a device and method for multimodal collaborative trapping of flying insects to form a continuous trapping path, thereby improving the trapping effect of all types of indoor flying insects without increasing heating power consumption.

[0005] To achieve the above objectives, this application provides a multimodal collaborative insect trapping device, comprising a cylinder, wherein the interior of the cylinder is provided with a light-emitting passive biomimetic thermal component capable of multi-band light emission and passive biomimetic thermal trapping of insects, and the cylinder is provided with a plurality of insect trapping stations. The light-emitting passive biomimetic thermal component includes a lamp plate bracket, a flow-guiding chimney structure on the upper side of the lamp plate bracket, an attractant container below the lamp plate bracket, a light-emitting component on the outer side of the lamp plate bracket, and several heat gas passages on the lamp plate bracket for connecting the flow-guiding chimney structure and the attractant container. When the light-emitting component attracts flying insects with its light, the heat generated by the light-emitting component itself can form a thermosiphon airflow through the heat gas passage, thereby conveying the attractant odor generated by the attractant container upwards and dissipating it through the guide chimney structure.

[0006] This application provides some specific embodiments, wherein the light-emitting component adopts a multi-band LED light board, which is a 365nm ultraviolet LED light board, a 395nm ultraviolet LED light board and a 455nm blue LED light board.

[0007] This application provides some specific embodiments. The flow-guiding chimney structure includes a top cover one and a top cover two arranged vertically. A plurality of attractant dispersion holes are formed between the top cover one and the top cover two, which are connected to the heat gas passage. A nylon mesh is provided between the attractant dispersion holes and the heat gas passage.

[0008] This application provides some specific embodiments, wherein the bottom side of the lamp panel bracket is provided with a support, the upper side of the attractant container is open and a bracket lower cover is provided at the opening, and the bracket lower cover is provided with a vent hole communicating with the heat gas passage.

[0009] This application provides some specific embodiments, wherein a base is detachably provided on the bottom side of the cylinder, and the base is provided with a plurality of ventilation slots for providing a cold air source for the thermosiphon airflow.

[0010] This application provides some specific embodiments. The light-emitting component is provided with a transparent lampshade on its outer side. The transparent lampshade is made of high-transparency borosilicate quartz glass material. The transparent lampshade is disposed between the top cover and the support. Waterproof and shockproof silicone rings are respectively provided at the connection between the transparent lampshade and the top cover and the support.

[0011] This application provides some specific embodiments. The top side of the cylinder has several insertion slots for inserting bait cards into the insect-catching positions. These insertion slots correspond one-to-one with the insect-catching positions. The side wall of the cylinder has several longitudinally elongated slots, the number of which matches the number of insect-catching positions and are staggered. (Insect-catching position)

[0012] This application provides some specific embodiments, wherein the upper edge of the attractant container has a plurality of lugs protruding therefrom, and the inner side wall of the lower cover of the support has protruding buckles that correspond one-to-one with the lugs. The attractant container can be detachably installed on the lower cover of the support by means of the lugs and buckles cooperating.

[0013] This application provides some specific embodiments. The lamp board bracket is made of hexagonal plastic parts, the substrate of the LED lamp board is made of aluminum substrate, the six sides of the lamp board bracket are provided with longitudinal slots for inserting the aluminum substrate, and the mating surface of the aluminum substrate and the lamp board bracket is provided with a plurality of heat dissipation grooves that are evenly distributed and communicate with each other with heat dissipation air passages.

[0014] A method for multimodal cooperative trapping of flying insects includes the following steps: S1: Multi-band layered light emission attraction, each LED panel of the light emission passive biomimetic thermal component emits 365nm ultraviolet light, 395nm ultraviolet light and 455nm blue light respectively. The 365nm ultraviolet light and 395nm ultraviolet light radiate outward toward the opening slot of the cylinder to attract flying insects at a distance, and the 455nm blue light is directed toward the flying insect capture station (2) to achieve close-range attraction enhancement. S2: The thermosiphon airflow dissipates odors. The LED light board generates heat during operation. The heat is introduced into the heat air passage of the light board bracket through the heat dissipation groove. The air inside the heat air passage is heated and rises to form a negative pressure. The ventilation groove of the base draws in cold air from the outside to form a circulating airflow. S3: The attractant odor is directed by the flow-guiding chimney structure. The odor generated by the attractant container is transported upward along the heat gas passage. The odor is sprayed out from the attractant vent between the top cover one and the top cover two. The airflow is transported towards the flying insect capture station and the insertion slot (102) area, thereby guiding the flying insect to the flying insect capture station. S4: The transparent lampshade accumulates the residual heat of the LED light panel to form a heat radiation area that simulates the human body surface. When flying insects approach the opening slot of the tube, they receive heat radiation and 455nm blue light to form a dual attraction signal. S5: A continuous trapping path is formed by multiple layers of trapping signals. Long-distance multi-band ultraviolet light, medium-distance directional odor airflow, and short-distance biomimetic heat-plus-blue light signals are sequentially formed to guide flying insects through the trapping path to contact the flying insect capture station, where they are trapped and fixed by the trapping adhesive card on the flying insect capture station.

[0015] The beneficial effects are: 1. By relying on the residual heat of the light source to form a passive thermosiphon airflow, it simultaneously outputs multi-band light signals, human biomimetic thermal radiation signals, and directional odor signals, constructing a three-level continuous trapping path of far, medium and near range, and improving the trapping effect of all types of indoor flying insects without increasing heating power consumption.

[0016] 2. This application transforms light, heat, and gas path into an interdependent thermodynamic system. The gas path draws away waste heat to stabilize the biomimetic heat source, and the heat source in turn feeds back into the gas path, truly achieving a synergistic trapping effect of 1+1+1>3. It deeply couples the three trapping mechanisms of light, heat, and odor to form a continuous trapping path.

[0017] 3. The double-layered top cover combined with the insect-proof nylon mesh guide chimney structure not only enables the odor to be sprayed in a directional manner to the trapping area, but also prevents small insects and insect carcasses from blocking the heat air passage, thus solving the defects of traditional odor trapping equipment such as scattered odor and easy blockage of the inner cavity.

[0018] 4. The LED light board uniformly uses an aluminum substrate as the carrier. The aluminum substrate can quickly dissipate the heat generated by the LED operation. The heat dissipation grooves opened on the back of the aluminum substrate are directly connected to the heat air passage, which can directly send the heat dissipated by the aluminum substrate into the heat air passage, providing a stable heat source for the thermosiphon airflow.

[0019] 5. Nylon mesh can physically prevent fruit flies and small flying insects from entering the heat and air passages and causing blockages. On the other hand, the high permeability of the mesh will not hinder the upward flow of hot air and odors, thus achieving the dual function of insect prevention and airflow.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. Furthermore, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] Example 1: See Figures 1-8As shown, this embodiment provides a multimodal collaborative insect trapping device, including a cylindrical body 1 with a cylindrical outline. Three or more insect-catching stations 2 are provided on the upper side wall of the body 1. Each insect-catching station 2 is used to insert an insect-catching adhesive card 15, serving as a fixed area for insect capture. In practical applications, the top of the body 1 has a three-part injection-molded structure, corresponding to the three insect-catching stations 2.

[0026] A light-emitting passive bionic heating component 3 is installed at the center of the cylinder 1. The light-emitting passive bionic heating component 3 can simultaneously output multi-band insect-attracting light and generate bionic heat radiation that simulates the human body surface by relying on its own working waste heat, which simultaneously drives the internal odor circulation airflow.

[0027] The luminous passive bionic thermal component 3 includes a lamp plate bracket 306, which is made of hexagonal plastic. The hollow cavity inside the lamp plate bracket 306 forms a heat gas passage 308, which connects the bottom attractant container 7 with the top guide chimney structure.

[0028] The upper side of the lamp plate bracket 306 is equipped with a flow-guiding chimney structure. The flow-guiding chimney structure relies on the rising of internal hot air to form a chimney effect, which can directionally transport the attractant odor volatilized at the bottom to the flying insect capture station 2 on the side wall of the cylinder 1. The attractant container 7 is placed below the lamp plate bracket 306. The attractant container 7 is used to store flying insect attractant and continuously release insect attractant odor. The outer side of the lamp plate bracket 306 is equipped with a light-emitting component. The light-emitting component is responsible for emitting insect attractant light sources of different wavelengths. At the same time, it continuously generates heat during operation, providing a heat source for thermosiphon airflow and biomimetic thermal radiation. Multiple heat air passages 308 are arranged through the inside of the lamp plate bracket 306. The heat air passages 308 connect the lower attractant container 7 and the upper flow-guiding chimney structure, serving as dedicated channels for the upward transport of heat and odor.

[0029] When the light-emitting component is powered on and emits light, continuously generating working heat, the waste heat generated by the light-emitting component will be introduced into the heat air passage 308. After being heated, the air inside the passage rises rapidly, forming a negative pressure environment inside the cavity, which in turn generates a stable thermosiphon airflow. The airflow will continuously sweep over the agent inside the attractant container 7, carrying the volatile insect-attracting odor upward along the passage, and finally being directionally emitted outward by the top guide chimney structure, completing the targeted output of the odor signal.

[0030] Example 2: Based on Example 1, this embodiment refines and defines the structure of the light-emitting component. The light-emitting component is composed of multiple LED light boards 304 of various wavelengths. The multiple LED light boards 304 of various wavelengths are a 365nm ultraviolet LED light board, a 395nm ultraviolet LED light board, and a 455nm blue light LED light board.

[0031] The 365nm and 395nm ultraviolet LED panels output long-distance, broad-spectrum ultraviolet light, which is adapted to the phototaxis of flies, mosquitoes, and moths at long distances, and is responsible for attracting flying insects over a wide area throughout the house; the 455nm blue LED panel is arranged facing the opening on the side wall of the cylinder 1, outputting strong visual stimulation at close range, and enhancing the attraction behavior of flying insects after they approach.

[0032] The LED panel bracket 306 has six integrally formed longitudinal slots 314 on its six sides. These slots 314 are used to engage and secure each LED panel 304, enabling rapid assembly and positioning. The LED panels 304 uniformly use an aluminum substrate as the carrier. The aluminum substrate has excellent thermal conductivity, allowing for rapid dissipation of heat generated by the LEDs. (See attached instruction manual.) Figure 9 As shown, multiple heat dissipation grooves 315 with a depth of 5mm are evenly opened on the back of the aluminum substrate and the lamp board bracket 306. The heat dissipation grooves 315 are directly connected to the heat air passage 308, which can directly send the heat conducted by the aluminum substrate into the heat air passage 308, providing a stable heat source for the thermosiphon airflow.

[0033] Example 3: Based on Example 1, this embodiment refines the design of the flow-guiding chimney structure. The flow-guiding chimney structure is composed of two layers: a first top cover 301 and a second top cover 302. The first top cover 301 serves as the top sealing component, and the second top cover 302 serves as the middle partition support component. After assembly, multiple long strip-shaped attractant dispersion holes 311 are formed on the side. The attractant dispersion holes 311 are fully connected to the lower heat gas passage 308 and are the outlets for the outward spray of odor gas. The dispersion holes are opened towards the flying insect capture station 2 on the side wall of the cylinder to ensure that the odor is directionally delivered to the sticky insect area.

[0034] A nylon mesh 307 is provided between the attractant emitting hole 311 and the heat air passage 308. The nylon mesh 307 is specifically located between the top cover 302 and the lamp plate bracket 306. The mesh diameter of the nylon mesh 307 is less than 1mm. On the one hand, it can physically prevent fruit flies and small flying insects from drilling upward into the heat air passage 308 and causing blockage. On the other hand, the mesh has high permeability and will not hinder the upward flow of hot air and odor, thus taking into account both insect prevention and airflow.

[0035] Example 4: Based on Example 1, this embodiment further refines and defines the bottom air intake of the whole machine and the disassembly and assembly structure of the attractant container 7.

[0036] The bottom side of the lamp plate bracket 306 is integrally formed with a support 309. The support 309 serves as an intermediate support structure, separating the bottom attractant container 7 from the central light-emitting component. The attractant container 7 has an opening at the top, and the opening is fitted with a bracket lower cover 310. The bracket lower cover 310 seals the attractant cavity and diverts the airflow. Multiple sets of ventilation holes 312 are opened on the surface of the bracket lower cover 310. The ventilation holes 312 connect the inside of the attractant container 7 with the upper heat gas passage 308. The odor of the drug can be smoothly transported upward through the ventilation holes 312 into the gas passage.

[0037] The bottom side of the cylinder 1 is detachably equipped with a base 5. Specifically, the base 5 is fixed to the cylinder by magnetic attraction. After removal, the attractant inside the attractant container 7 can be replaced. Multiple ventilation slots 501 are evenly opened on the bottom edge of the base 5. The ventilation slots 501 are the cold air intake channels of the whole machine. When the heat air passage 308 forms a negative pressure, the ambient cold air will be drawn into the bottom of the equipment from the ventilation slots 501 to continuously replenish the airflow and maintain the stable operation of the thermosiphon circulation.

[0038] Multiple sets of lugs 701 protrude outward from the upper edge of the attractant container 7, and multiple sets of buckles 313 protrude correspondingly on the inner wall of the lower cover 310 of the bracket. The lugs 701 and buckles 313 are matched and engaged one by one. After disassembling the base 5, the attractant container 7 can be quickly disassembled and assembled by screwing the buckles together. Attractant replenishment and container cleaning can be completed without additional tools.

[0039] Example 5: This embodiment, based on Embodiment 1, adds external protection and heat storage structure limitations for the light-emitting component. A transparent lampshade 303 is completely wrapped around the outside of the light-emitting component. The transparent lampshade 303 is made of high borosilicate quartz glass. On the one hand, it isolates dust and insect remains, preventing contamination and damage to the LED light panel 304. On the other hand, the quartz material has strong heat storage capacity, which can trap residual heat conducted by the aluminum substrate, keeping the outer surface of the lampshade stably maintained at 34°C to 38°C, simulating human body surface temperature and forming a near-field biomimetic thermally induced signal. Simultaneously, the high-transmittance borosilicate quartz glass has good light transmission and low light loss, which is conducive to the efficient radiation of ultraviolet, near-ultraviolet, and blue light in all directions. The upper and lower ends of the transparent lampshade 303 abut against the top cover 302 and the support 309 respectively. Waterproof silicone rings 305 are fitted at the joints of both ends of the lampshade. The waterproof silicone rings 305 fill the assembly gaps and prevent water vapor and small insects from entering the internal circuit and LED light board 304 through the gaps, thereby improving the waterproof and dustproof performance of the whole machine. It also has a certain shockproof and dustproof function.

[0040] See instruction manual attached Figure 1 and Figure 10As shown, the top side of the cylinder 1 has several insertion slots 102 for inserting the bait adhesive card 15 into the insect capture station 2. The insertion slots 102 and the insect capture station 2 correspond one-to-one. The side wall of the cylinder 1 has three or more longitudinally elongated slots 101, which are the same number as the insect capture stations 2 and are distributed alternately. The slots 101 serve as channels for insects to enter the cylinder 1. The bait adhesive card 15 can be inserted from top to bottom into the insect capture station 2 through the insertion slots 102. The insect capture station 2 has two opposing locking strips with an L-shaped cross-section, which facilitates locking the bait adhesive card 15 after insertion, allowing for replacement without power interruption. In addition, corresponding to the three opening slots 101, each opening slot 101 is equipped with a light panel containing one 365nm ultraviolet LED and one 395nm ultraviolet LED, which undertakes the task of attracting insects from a distance and with a wide spectrum. Corresponding to the three insect capture stations 2, each insect capture station 2 is equipped with a light panel containing two 455nm blue LEDs, which provides strong visual guidance at close range, prompting insects to collide with the sticky plate. In practical applications, the insect capture station 2 can use a trap sticky card 15, but it is not limited to this. Electric grids, insect sticky nets, etc. can also be used to capture insects.

[0041] This device also includes a power adapter 4, a bio-touch switch 6, a touch button switch circuit board 8, electrical wires 9, a busbar circuit board 10, and a power circuit board 11, as detailed in the instruction manual. Figure 6 As shown, the touch button switch circuit board 8 is electrically connected to the bus circuit board 10 and the power circuit board 11 via electrical wires 9.

[0042] Example 6: This embodiment uses any one of the multimodal collaborative insect trapping devices from Embodiments 1 to 5 to perform the trapping method. The complete trapping process consists of five consecutive steps, which cooperate with each other to form a three-level continuous trapping path of far, medium and near range. The specific operation steps are as follows: S1: Multi-band layered emission for long-distance induction, see instruction manual. Figure 10As shown, after the device is powered on by the power adapter 4, the LED panels 304 inside the passive bionic thermal component 3 light up synchronously, emitting 365nm ultraviolet light, 395nm ultraviolet light, and 455nm blue light respectively. The 365nm and 395nm ultraviolet light radiate omnidirectionally around the opening slot 101 facing the cylinder 1. Relying on the broad-spectrum insect-attracting properties of ultraviolet light, it attracts various flying insects in the room to approach the device within a range of 3m to 5m. Once the insects attracted by the light source enter the 0.5m to 3m odor diffusion range, the directional high-concentration odor flow emitted by the guide chimney structure directly guides the insects to the flying insect capture station 2. Within a close distance of 0-0.5m, when the flying insects approach the opening slot 101, they feel the uniform body temperature radiation of 34℃-38℃. The 455nm blue light is arranged towards the area of ​​the trap adhesive card 15 in the cylinder 1 to achieve close-range attraction enhancement, causing them to completely lower their guard and rush towards the light-emitting component, and finally be captured by the trap adhesive card 15. The three methods of luring complement each other, resulting in a success rate of 1+1+1>3.

[0043] For details, please refer to the instruction manual. Figure 10 As shown, the trapping area can be divided into three or more first-modal trapping areas 12 and second-modal trapping areas 13, wherein the first-modal trapping areas 12 and second-modal trapping areas 13 are designed to be spaced apart and intersected with each other; The first modal trapping zone 12 consists of a first inner trapping zone 1201, a first middle trapping zone 1202, and a first outer trapping zone 1203, extending from the center of the cylinder 1 outwards. The first inner trapping zone 1201 contains UVA ultraviolet light, visible ultraviolet light, odor, and thermal infrared light. The first middle trapping zone 1202 contains UVA ultraviolet light, visible ultraviolet light, and odor. The first outer trapping zone 1203 contains UVA ultraviolet light and visible ultraviolet light. The second modal trapping zone 13 consists of a second inner trapping zone 1301, a second middle trapping zone 1302, and a second outer trapping zone 1303, which are located from the center of the cylinder 1 to the outside. The second inner trapping zone 1301 is equipped with UVA ultraviolet light, visible ultraviolet light, odor, thermo-biomimetic light, thermal infrared light, and blue light. The second middle trapping zone 1302 is equipped with odor and thermal infrared light. The second outer trapping zone 1303 is equipped with odor.

[0044] S2: The waste heat of the light-emitting component generates a thermosiphon airflow. During the continuous operation of the LED light board 304, heat is stably generated. The heat is directly introduced into the heat air passage 308 inside the light board bracket 306 through the heat dissipation groove 315 on the back of the aluminum substrate. The air inside the passage expands and flows upward rapidly due to the heat. A negative pressure area is formed at the lower end of the air passage. The ventilation groove 501 at the bottom of the base 5 continuously draws in ambient cold air. The cold air passes over the agent inside the attractant container 7, completing the odor entrainment and forming a continuously circulating thermosiphon airflow.

[0045] S3: The guide chimney structure directs the attraction odor, and the hot airflow carrying the high concentration of insect-attracting odor is transported upward along the heat air passage 308 to the top guide chimney structure. The airflow is ejected laterally from the attractant dispersion hole 311 between the top cover 1 301 and the top cover 2 302. The dispersion hole is arranged facing the flying insect capture station 2 on the side wall of the cylinder 1. The airflow carrying the odor blows towards the area of ​​the trap sticky card 15, forming a directional odor guiding channel in the medium distance range of 0.5 to 3 meters, continuously guiding the flying insects attracted by the light source to the trap position.

[0046] S4: The transparent lampshade 303 made of high-transparency borosilicate quartz glass outside the light-emitting component continuously accumulates the residual heat of the LED operation. The outer surface of the transparent lampshade 303 maintains a constant temperature heat radiation area of ​​34 to 38 degrees Celsius. When the flying insect moves to the 0 to 0.5 meter close range in front of the opening slot 101 of the cylinder 1, it simultaneously receives the bionic human body heat radiation signal and the 455nm blue light visual signal. The dual trapping signals greatly reduce the flying insect's vigilance, prompting the flying insect to actively approach the opening slot 101 or the insertion slot 102 of the petal-shaped opening area at the top.

[0047] S5: The three-level trapping signals work together to complete the trapping and fixation. The long-distance multi-band ultraviolet light, the medium-distance directional odor airflow, and the short-distance biomimetic heat-plus-blue light signal form a continuous and uninterrupted trapping path in sequence. The flying insects move continuously along the trapping path towards the flying insect capture station 2 of the cylinder 1. Finally, when they reach the flying insect capture station 2, they are captured and fixed after contacting the high-strength adhesive on the surface of the trapping adhesive card 15, thus completing the trapping of flying insects.

10. A method for multimodal collaborative trapping of flying insects, employing the multimodal collaborative trapping device according to any one of claims 1-9, characterized in that: Includes the following steps: S1: Multi-band layered light emission attraction, each LED panel (304) of the light emission passive biomimetic thermal component (3) emits 365nm ultraviolet light, 395nm ultraviolet light and 455nm blue light respectively. The 365nm ultraviolet light and 395nm ultraviolet light radiate outward toward the opening slot (101) of the cylinder (1) to attract flying insects at a distance. The 455nm blue light is arranged toward the flying insect capture station (2) of the cylinder (1) to enhance the attraction at a close distance. S2: The thermosiphon airflow dissipates the odor. The LED light board (304) generates heat during operation. The heat is introduced into the heat air passage (308) of the light board bracket (306) through the heat dissipation groove (315). The air inside the heat air passage (308) is heated and rises to form a negative pressure. The ventilation groove (501) of the base (5) draws in cold air from the outside to form a circulating airflow. S3: The attractant odor is directed by the flow-guiding chimney structure. The odor generated by the attractant container (7) is transported upward along the heat gas passage (308). The odor is sprayed out from the attractant vent (311) between the top cover one (301) and the top cover two (302). The airflow is transported towards the flying insect capture station (2) and the insertion slot (102) area, thereby guiding the flying insect to the flying insect capture station (2). S4: The transparent lampshade (303) accumulates the residual heat of the LED lamp panel (304) to form a heat radiation area that simulates the human body surface. When the flying insect approaches the opening slot (101) of the cylinder (1), it receives heat radiation and 455nm blue light to form a dual attraction signal. S5: A continuous trapping path is formed by multiple layers of trapping signals. The long-distance multi-band ultraviolet light, the medium-distance directional odor airflow, and the short-distance biomimetic heat-plus-blue light signal form a continuous trapping path in sequence, guiding the flying insects through the trapping path to contact the flying insect capture station (2), and being trapped and fixed by the trapping adhesive card (15) on the flying insect capture station (2).
