Description

Technical Field

[0001] This utility model relates to the field of mosquito attraction technology, specifically an escape-proof mosquito attractant lamp. Background Technology

[0002] With global climate change and increased international exchange, the risk of imported and reinfected mosquito-borne infectious diseases such as malaria and dengue fever is constantly rising. Mosquito vector surveillance is of great significance; it is the foundation for early warning and prevention of mosquito-borne infectious diseases and for mosquito control, as well as a means of evaluating the effectiveness of mosquito control measures. By monitoring mosquito vectors, we can understand the distribution, density, and seasonal variation patterns of mosquito populations, promptly identify and warn of potential risks of mosquito-borne diseases, and provide a scientific basis for developing targeted prevention and control strategies, thereby effectively safeguarding the health and safety of the public.

[0003] According to the "Notice of the Chinese Center for Disease Control and Prevention on Issuing the National Vector-borne Disease Monitoring Implementation Plan" (Zhong CDC Transmission Prevention and Control Document No. 56

[2016] ), mosquito monitoring is an important component of vector-borne disease monitoring, among which adult mosquito density monitoring is of great significance for the prevention and control of mosquito-borne diseases. The mosquito-attracting lamp method has become one of the main means of adult mosquito density monitoring due to its ease of operation and wide applicability.

[0004] However, although mosquito-attracting lamps are widely used in mosquito vector monitoring, in daily monitoring, the negative pressure generated by the fan to suck mosquitoes into the collector is often insufficient. Generally, the fan power of mosquito-attracting lamps is relatively low, resulting in a relatively weak suction force. This cannot guarantee sufficient suction to effectively pull mosquitoes into the collector, leading to a lower collection rate per unit time. Furthermore, it exposes another problem: the mosquito escape rate is increased, as captured mosquitoes easily escape, thus reducing the accuracy of monitoring results. Ultimately, mosquito-attracting lamps are slow to capture mosquitoes and capture fewer mosquitoes, thus affecting monitoring efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an escape-proof mosquito-attracting lamp to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an escape-proof mosquito-attracting lamp, comprising a hollow shell and a collection box installed at the bottom of the hollow shell, a top plate fixed to the inner wall of the upper opening of the hollow shell, the top plate having a plurality of light-transmitting holes arranged in a ring structure axially, a plurality of air guide plates fixed to the bottom wall of the top plate between two adjacent light-transmitting holes, an air storage chamber for temporary air storage provided inside the top plate, the air storage chamber being independently distributed from the light-transmitting holes, an air outlet cavity being opened on the air guide plates, the upper opening of the air outlet cavity communicating with the air storage cavity, the bottom ends of the plurality of air guide plates being spirally curved and extended, and the bottom opening of the air outlet cavity being inclined downwards;

[0007] Multiple air outlet cavities have inclined openings at the bottom, blowing air through the openings at the bottom of multiple light-transmitting holes, forming a blowing area located below the multiple light-transmitting holes, thus blocking the passage of mosquitoes to fly out of the light-transmitting holes.

[0008] It also includes a light tube built into the hollow shell. When the light tube is powered on, it projects light through the light-transmitting hole onto the outside of the hollow shell to attract and trap mosquitoes.

[0009] In a further embodiment, the bottom openings of multiple air outlet cavities are tilted to blow air, with airflow occurring both longitudinally and laterally.

[0010] In a further embodiment, a hanging rod is fixedly inserted into the center of the top plate, the bottom end of the hanging rod extends to the lower part of the hollow shell and is fixed with a lamp holder, and multiple lamp tubes are provided and evenly installed on the upper surface of the lamp holder;

[0011] The upper surface of the lamp holder is also fitted with a transparent lamp cover that covers the outside of multiple lamp tubes.

[0012] In a further embodiment, the lamp tube projects a 420nm monochromatic LED light source.

[0013] In a further embodiment, a rainproof canopy with a built-in lithium battery is also included. The top end of the hanging rod is fixedly connected to the bottom wall of the rainproof canopy. A connecting rod is fixed between the bottom wall of the rainproof canopy and the top wall of the hollow shell. A conductive wire is connected between the terminals of the lithium battery and the lamp tube. The hanging rod is provided with a through hole in the axial direction for the conductive wire to pass through.

[0014] In a further embodiment, a fan is installed on the bottom wall of the lamp holder, and a conductive wire is connected between the fan and the terminal of the lithium battery. A hollow air inlet box is installed below the fan.

An air guide pipe is connected to the lower end of the side wall of the hollow air inlet box, and an air inlet connected to the upper end of the air guide pipe is opened on the bottom wall of the top plate. The air inlet is connected to the air storage chamber.

[0015] In a further embodiment, the bottom wall of the rainproof canopy is fixed with an inverted frustum-shaped stainless steel reflector, and the inclined sidewalls of the stainless steel reflector are used to reflect the light projected by the lamp tube laterally.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model is an escape-proof mosquito-attracting lamp that uses a 420nm monochrome LED light source to attract and trap mosquitoes. After the mosquitoes fly into the hollow shell through multiple light-transmitting holes, they are blown by the oblique wind from the bottom openings of multiple air outlet cavities, and continue to fly downwind into the hollow shell. The obliquely blown wind forms a blowing zone below the multiple light-transmitting holes, blocking the mosquitoes' flight path out of the light-transmitting holes, thus preventing them from flying upwards and back into the light-transmitting holes to escape. This ensures that the collection efficiency and quantity per unit time can meet the monitoring requirements, thereby ensuring the effective subsequent mosquito monitoring. It is simple and practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This embodiment provides an escape-proof mosquito-attracting lamp, such as... Figure 1 and Figure 2As shown, the device includes a hollow outer shell 5 and a collection box 6 installed at the bottom of the hollow outer shell 5. A top plate 8 is fixed to the inner wall of the opening at the top of the hollow outer shell 5. The top plate 8 has multiple light-transmitting holes 15 arranged in a ring structure along its axial direction. It also includes a rainproof canopy 1 with a built-in lithium battery. A hanging rod 3 is fixedly inserted into the center of the top plate 8. The top end of the hanging rod 3 is fixedly connected to the bottom wall of the rainproof canopy 1. A connecting rod 4 is fixed between the bottom wall of the rainproof canopy 1 and the top wall of the hollow outer shell 5. The rainproof canopy 1 and the hollow outer shell 5 are assembled together by the connecting rod 4. The collection box 6 is threadedly connected to the hollow outer shell 5. The collection box 6 can be separated from the hollow outer shell 5 by rotating it in the opposite direction. The diameter of the rainproof canopy 1 is larger than the diameter of the hollow outer shell 5. When attracting mosquitoes, it is placed outdoors to prevent rainwater from entering the hollow outer shell 5 when it rains.

[0027] It also includes a lamp tube 14 built into the hollow housing 5, specifically, such as Figure 3 , Figure 4 As shown, the bottom end of the hanging rod 3 extends to the lower part of the hollow outer shell 5 and is fixed with a lamp holder 13. Multiple lamp tubes 14 are evenly installed on the upper surface of the lamp holder 13. A conductive wire connects the lithium battery and the wiring terminals of the lamp tubes 14. The hanging rod 3 has an axial through-hole for the conductive wire to pass through. A charging port for the lithium battery can be set on the bottom wall of the rainproof canopy 1, and the lithium battery powers the lamp tubes 14. It is worth noting that the lamp tubes 14 project a 420nm monochromatic LED light source. In its mosquito vector monitoring work, the applicant found that light waves with wavelengths in the range of 360-450nm generally have a strong attraction to mosquitoes; therefore, selecting wavelengths within this range is ideal. However, it should also be noted that different mosquito species have slightly different sensitivities to light waves, so in practical applications, selection and adjustment may be necessary based on specific circumstances. Reference "Design of a Multispectral Mosquito-Attracting Experimental Device and Study on Mosquito Phototaxis. Agriculture and Technology [J]. 2020, 40(23):28-31", the results of the unmanned darkroom experiment showed that Culex mosquitoes have a clear attraction to ultraviolet and blue-violet light sources, especially light sources of 365nm, 405nm, 420nm and 450nm. Among them, the 365nm and 420nm light sources have the most outstanding mosquito-attracting performance, and there is no significant difference in the mosquito-attracting effect between the two. In addition, Culex mosquitoes showed a strong photophobia to yellow light. The results of the indoor experiment with people present showed that in the room with people moving around, the mosquito-attracting effect of the 420nm monochromatic LED light source was the best. Therefore, the mosquito-attracting lamp with the 420nm monochromatic LED light source has more advantages. These light sources can emit light waves that mosquitoes are sensitive to, thereby attracting mosquitoes to approach the mosquito attractor.

[0028] When the light tube 14 is powered on, it illuminates and projects light through the light-transmitting hole 15 onto the hollow outer shell 5 to attract and trap mosquitoes.

[0029] Once a mosquito is trapped inside its hollow shell 5, it needs to be prevented from escaping. Therefore, such as... Figure 3 , Figure 5 and Figure 6 As shown, the bottom wall of the top plate 8 has multiple air guide plates 9 fixed between two adjacent light-transmitting holes 15. The top plate 8 has an air storage chamber for temporary air storage. At the same time, a fan is installed on the bottom wall of the lamp holder 13. A conductive wire is also connected between the fan and the terminal of the lithium battery. A hollow air inlet box 12 is installed below the fan. The fan has fan blades that are rotatably installed in the hollow air inlet box 12. An air inlet mesh is opened at the upper end of the outer wall of the hollow air inlet box 12. An air guide pipe 10 is connected to the lower end of the side wall of the hollow air inlet box 12. An air inlet is opened on the bottom wall of the top plate 8 and connected to the upper end of the air guide pipe 10. The air inlet is connected to the air storage chamber.

[0030] The air storage chamber and the light-transmitting holes 15 are independently distributed. This means the fan provides rotational power for the fan blades. Air enters the hollow air inlet box 12 through the air inlet mesh and is guided into the air storage chamber through the side air guide pipes 10. The air guide vanes 9 have outlet cavities, the upper opening of which connects to the air storage chamber. Multiple air guide vanes 9 are arranged in a spiral structure with their bottom ends bent and extended, and the bottom openings of the outlet cavities are inclined downwards. The air in the air storage chamber is blown out along the bottom openings of the outlet cavities of the bent and extended air guide vanes 9, forming a downward-sloping airflow.

[0031] Multiple air outlet cavities have inclined openings at their bottom ends, blowing air that passes below the bottom openings of multiple light-transmitting holes 15, forming a blowing area below the light-transmitting holes 15, thus blocking the passage of mosquitoes to fly out through the light-transmitting holes 15; for example Figure 6 As shown, multiple air outlet cavities have inclined openings at their bottom ends, blowing air both longitudinally and laterally. The air blown out at these angles is like... Figure 6 The wind, as indicated by q, blows laterally along the direction indicated by q1 and longitudinally along the direction indicated by q2. The advantage of this blowing is that the wind passes through the bottom openings of multiple light-transmitting holes 15, making it difficult for the mosquitoes already trapped inside the hollow shell 5 to remain stable within the plane of the lateral wind. The mosquitoes are small and easily blown away by the wind, preventing them from flying towards the light-transmitting holes 15 and escaping through the upper openings. This ensures that trapped mosquitoes will not escape. The longitudinal wind blows the trapped mosquitoes downwards, preventing them from congregating in the upper part of the hollow shell 5 and directing them towards the collection box 6 for later centralized killing and removal.

[0032] In summary, the above structure uses a 420nm monochromatic LED light source to trap mosquitoes. After mosquitoes fly into the hollow outer shell 5 through multiple light-transmitting holes 15, they are subjected to oblique winds blown from the bottom openings of multiple air outlet cavities. The obliquely blown winds form a blowing zone below the multiple light-transmitting holes 15, blocking the mosquitoes' escape route from the light-transmitting holes 15. Consequently, they cannot fly upwards and back into the light-transmitting holes 15 to escape, ensuring that the collection efficiency and quantity per unit time can meet the monitoring requirements, thus guaranteeing the effective conduct of subsequent mosquito monitoring. In fact, the core design point is to change the direction of the wind by arranging an obliquely downward blowing zone around the upper end of the lamp tube 14, forming an obliquely downward thrust that blows mosquitoes into the mosquito-attracting device. Due to wind resistance, they cannot escape outwards and can only enter the collection box 6 below the light source along the wind direction, thereby improving the trapping efficiency.

[0033] Meanwhile, a transparent lampshade 11 is also installed on the upper surface of the lamp holder 13, which is fitted over the outside of multiple lamp tubes 14, such as Figure 4 As shown, the transparent lampshade 11 can be made of transparent acrylic sheet, which does not affect light transmission. At the same time, it prevents mosquitoes from attaching to the surface of the lamp tube 14, making it inconvenient to clean.

[0034] Furthermore, an inverted frustum-shaped stainless steel reflector 2 is fixed to the bottom wall of the rainproof canopy 1. The inclined sidewalls of the stainless steel reflector 2 are used to reflect the light projected by the lamp tube 14 laterally, thereby expanding the trapping range.

[0035] Also, such as Figure 1 As shown, a stainless steel mesh 7 is embedded in the side wall of the collection box 6. The stainless steel mesh 7 is transparent, making it convenient for staff to observe the collection situation inside the collection box 6. Of course, the stainless steel mesh 7 can also be used to chemically kill mosquitoes inside the collection box 6 and the hollow outer shell 5. Afterwards, the collection box 6 and the hollow outer shell 5 can be separated for easy counting and detection.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
