Description

Technical Field

[0001] This application relates to the field of mosquito control technology, and in particular to a mosquito trapping system and method. Background Technology

[0002] Mosquitoes are carriers of many pathogens, such as malaria and dengue fever. How to effectively control mosquitoes has become an important issue in the field of public health. Among them, mosquito trapping technology based on carbon dioxide (CO2) has become a research hotspot in the field of mosquito control in recent years due to its environmental protection and high efficiency.

[0003] Existing CO2-based mosquito trapping devices mainly rely on dry ice, CO2 cylinders, or propane combustion to generate CO2, which has drawbacks such as inconvenience, high cost, and difficulty in continuously and stably releasing CO2. For example, dry ice sublimates rapidly during transportation and storage; CO2 cylinders are bulky and require precise regulating valves to control the flow; propane combustion devices can cost over a thousand US dollars per unit, with monthly fuel costs approaching one hundred US dollars, which significantly limits the application and development of CO2-based mosquito trapping technology. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a mosquito trapping system and method that effectively utilizes CO2 in the air, which is convenient to use and has a low cost.

[0005] On one hand, this application provides a mosquito trapping system, comprising: a trapping module having a mosquito storage chamber capable of collecting and restricting mosquito escape; a CO2 module for releasing CO2 into a preset mosquito-attracting area to create a CO2 concentration field that attracts mosquitoes; a attractant module including a light attractant, a heat attractant, and / or an odor attractant module for forming a light, heat, and / or odor attractant field that attracts mosquitoes in the preset mosquito-attracting area; an airflow module for forming a directional airflow field in the preset mosquito-attracting area to guide mosquitoes attracted by the CO2 module and the attractant module into the mosquito storage chamber along a predetermined path; and a control module for coordinating the operation of the CO2 module, the attractant module, and the airflow module to create a multi-field coordinated mosquito-attracting environment.

[0006] On the other hand, this application provides a mosquito trapping method, including the following steps: constructing a CO2 concentration gradient field in a preset mosquito-attracting area to attract mosquitoes; superimposing a light-inducing field, a heat-inducing field, and / or an odor-inducing field in the preset mosquito-attracting area to further attract mosquitoes; and forming a directional airflow in the preset mosquito-attracting area to guide the attracted mosquitoes to a predetermined location.

[0007] Compared to existing technologies, this application constructs a CO2 concentration field, a light, heat and / or odor induction field, and a directional airflow field within a preset mosquito-attracting area through the coordinated operation of multiple modules. This forms a synergistic multi-physics induction environment that guides mosquitoes along a predetermined path into the capture module, significantly improving mosquito-attracting efficiency. Moreover, it uses specific materials to capture CO2 from the surrounding ambient air and then releases the captured CO2 through methods such as heating and humidification, which not only reduces usage costs and maintenance difficulties but also ensures air quality.

[0021] This application provides a mosquito trapping system and method, which can be applied indoors and outdoors, such as in courtyards, balconies, garages, squares, parks, dance halls, bars, and other places, to trap mosquitoes in the surrounding environment, improve sanitation, and reduce the spread of diseases. The mosquito trapping system of this application includes multiple cooperating modules, specifically, such as... Figures 1 to 3 As shown, it includes a CO2 module 20, a lure module 30, an airflow module 40, a capture module 50, and a control module 60, etc., wherein the control module 60 is used to coordinate the operation of other modules to achieve multi-physics field collaborative operation and improve the mosquito trapping efficiency.

[0022] The CO2 module 20 serves as a remote positioning source, releasing CO2 gas into a preset mosquito-attracting area to create a CO2 concentration gradient field that strongly attracts mosquitoes, thereby attracting mosquitoes within a range of tens or even hundreds of meters. The attractant module 30 serves as a near-field guiding source, releasing light, heat, and / or odors to further induce mosquitoes in the near field. The airflow module 40 forms a directional airflow, guiding the mosquitoes attracted by the CO2 module 20 and the attractant module 30 along a predetermined path into the capture module 50. Finally, the mosquitoes die in the capture module 50.

[0023] In one embodiment, such as Figure 2 , Figure 3 As shown, the CO2 module 20 includes a carbon capture unit 21, which uses specific materials to capture CO2 from the surrounding ambient air. The captured CO2 is then released through methods such as heating and humidification, continuously and stably outputting CO2 at a concentration similar to that of human exhaled gas towards a pre-set mosquito-attracting area in a controlled manner. On the one hand, the CO2 module 20 does not require replacement of the CO2 gas source, reducing operating costs and maintenance difficulty; on the other hand, since both the captured and released CO2 come from indoor ambient air, it does not additionally increase the CO2 concentration, ensuring air quality.

[0024] Specifically, the carbon capture unit 21 is filled with a porous adsorption material, which may be: active materials such as ion exchange resins, activated alumina, activated carbon, etc.; modified active materials such as modified alumina, modified activated carbon, etc.; or nanomaterials with added functional groups (such as amine or carboxyl groups) capable of binding CO2. At room temperature, the carbon capture unit 21 directly captures CO2 from the air; under specific conditions such as heating or humidification, CO2 desorbs from the carbon capture unit 21 and is continuously and stably released towards the predetermined trapping area in a controlled manner.

[0025] like Figure 2 , Figure 3 As shown, the CO2 module 20 also includes a fan 22 that cooperates with the carbon capture unit 21. When the fan 22 operates, it generates a forced airflow, allowing ambient air to flow through the carbon capture unit 21 during CO2 adsorption; and during CO2 desorption, it allows the CO2 to be emitted outwards. In the illustrated embodiment, the fan 22 is a vortex fan, with its inlet and outlet perpendicular to each other. After assembly, the inlet of the fan 22 faces downwards, and the outlet is horizontally positioned, with the carbon capture unit 21 located below the inlet of the fan 22.

[0026] like Figure 2 , Figure 3As shown, the CO2 module 20 further includes a heating unit 23 that cooperates with the carbon capture unit 21. The heating unit 23 includes a cavity shell 232 and an electric heating element 234 housed within the cavity shell 232. The cavity shell 232 has an inlet and an outlet on its upper and lower sides, respectively. The inlet communicates with the carbon capture unit 21, and the outlet communicates with the air inlet of the fan 22. The airflow is heated as it passes through the electric heating element 234, and the heated high-temperature airflow causes CO2 desorption as it passes through the carbon capture unit 21. Preferably, the CO2 module 20 further includes a vacuum pump 24 for drawing CO2 desorbed from the carbon capture unit 21.

[0027] In one specific embodiment, such as Figure 2 , Figure 4 As shown, a first air duct 25 and a second air duct 26 are respectively provided on both sides of the carbon capture unit 21, such as the left and right sides, and the first air duct 25 and the second air duct 26 are connected through the carbon capture unit 21. The bottom of the second air duct 26 is closed, and the top is connected to the inlet of the heating unit 23. In this way, the first air duct 25, the carbon capture unit 21, the second air duct 26, the heating unit 23, and the fan 22 can be connected sequentially.

[0028] In one specific embodiment, a third air duct 27 is further provided above the first air duct 25. A first air valve 90 is provided at the bottom of the first air duct 25, allowing the first air duct 25 to communicate with or disconnect from the external environment; a second air valve 92 is provided between the top of the first air duct 25 and the bottom of the third air duct 27, allowing the two to communicate with or disconnect; a third air valve 94 is provided at the top of the third air duct 27, allowing the third air duct 27 to communicate with or disconnect from the external environment.

[0029] The air outlet of the fan 22 is connected to the third air duct 27 via a pipe, thus enabling the fan 22, the third air duct 27, and the first air duct 25 to be connected sequentially. The inlet of the vacuum pump 24 is connected to the third air duct 27 via a pipe, and the outlet is connected to the CO2 release port 29 of the CO2 module 20 via a pipe, thus enabling the vacuum pump 24 to draw gas from the third air duct 27 to the CO2 release port 29 for discharge.

[0030] The mosquito-catching system also includes a housing 80 for mounting the CO2 module 20. The housing 80 can be a sheet metal part with a certain strength, providing support and protection for the internal components. An air inlet 82 is formed below the first air duct 25 on the housing 80. When the first air valve 90 is open, the first air duct 25 is connected to the external environment through the air inlet 82, allowing external air to flow to the carbon capture unit 21. An exhaust port 84 is formed above the third air duct 27 on the housing 80. When the third air valve 94 is open, the third air duct 27 is connected to the external environment through the exhaust port 84, allowing gas passing through the carbon capture unit 21 to be discharged to the outside through the third air duct 27.

[0031] like Figure 4 , Figure 5 As shown, when the CO2 module 20 adsorbs CO2 from the ambient air, the fan 22 starts, the first air valve 90 and the third air valve 94 open, and the second air valve 92 closes. Air from the external environment enters the housing 80 through the air inlet 82 at the bottom of the housing 80, flows through the first air valve 90 to the first air duct 25, and then flows through the carbon capture unit 21 to the second air duct 26. During the flow through the carbon capture unit 21, CO2 in the air is adsorbed onto the carbon capture unit 21.

[0032] During the above process, neither the heating unit 23 nor the vacuum pump 24 is activated. The gas, after CO2 removal by the carbon capture unit 21, flows through the heating unit 23 and the fan 22 to the third air duct 27. At this time, because the second air valve 92 is closed, the CO2-removed gas does not flow back to the first air duct 25, but flows through the third air valve 94 to the exhaust port 84 and is finally discharged to the outside through the exhaust port 84. In actual use, the CO2 module 20 can be activated during the day to adsorb CO2, with an adsorption time of 3-6 hours.

[0033] like Figure 6 , Figure 7 As shown, when CO2 needs to be released to trap mosquitoes, fan 22 is activated, second air valve 92 is opened, and first air valve 90 and third air valve 94 are closed. At this time, under the action of fan 22, the airflow circulates along first air duct 25, carbon capture unit 21, second air duct 26, heating unit 23, fan 22, and third air duct 27.

[0034] During this process, both the heating unit 23 and the air pump 24 are activated. The airflow is heated as it passes through the heating unit 23, and the heated high-temperature gas releases a large amount of adsorbed CO2 as it passes through the carbon capture unit 21. Thus, the air pump 24 can extract a high concentration of CO2 from the third air duct 27. In actual use, the CO2 module 20 can be activated at night to desorb CO2, and the desorption time can range from tens of minutes to several hours.

[0035] Figure 5 , Figure 6 In the diagram, the starting status of each air valve 90, 92, 94, the fan 22, the heating unit 23, and the air pump 24 is indicated by the symbol "—", and the non-starting status is indicated by the symbol "X".

[0036] In this application, the concentration of CO2 emitted from the CO2 release port 29 is preferably not less than 500 ppm. In a specific application, the overall dimensions of the device are 294mm*294mm*720mm, and the concentration of CO2 emitted from its CO2 release port 29 is mainly between 1000 and 6000 ppm. Specifically, after the CO2 module 20 has undergone adsorption for different durations (4h, 3h, and 4.5h respectively), the change in the concentration of CO2 emitted from the CO2 release port 29 over 3 hours is shown in Table 1 and the accompanying drawings. Figure 8 As shown: Table 1. Concentration values ​​of emitted CO2

[0037] From Table 1 and Figure 8 It can be seen that the peak concentration of emitted CO2 is generally above 5000 PPM. The longer the CO2 adsorption time, the more CO2 is adsorbed, and the higher the peak concentration of emitted CO2. Figure 1 It can be seen that the emitted CO2 concentration stabilizes at a relatively high level after 20 minutes, effectively attracting mosquitoes for up to 3 hours. This generally meets the needs of users during nighttime activities. In some applications, the device can be larger, with peak CO2 concentrations reaching 10,000 ppm.

[0038] In the above embodiments, the carbon capture unit 21 uses modified materials such as activated alumina and activated carbon. CO2 is desorbed by heating. After passing through the heating unit 23, the temperature of the gas flow through the carbon capture unit 21 is in the range of 65-80°C, ensuring both effective CO2 desorption and a long service life for the carbon capture unit 21. In some embodiments, the carbon capture unit 21 can also use ion exchange resins, etc. During CO2 desorption, the relative humidity can be increased to over 40% by a humidification unit, promoting rapid CO2 removal.

[0039] By switching on and off the first air valve 90, the second air valve 92, and the third air valve 94, the gas from which CO2 has been removed during CO2 adsorption can be promptly discharged to the outside through the exhaust port 84 of the outer casing 80. During CO2 desorption, CO2 is isolated from the air in the external environment and maintained at a high concentration. Finally, through the CO2 release port 29, CO2 with a concentration similar to that of human exhaled gas can be output, attracting mosquitoes within a radius of tens or even hundreds of meters. The switching on and off of the first air valve 90, the second air valve 92, and the third air valve 94 can all be driven by motors, preferably stepper motors, and then the control module 60 realizes automated control of the air valve switching.

[0040] The CO2 module 20 is configured to release CO2 periodically or in a pulsed manner to simulate the characteristics of CO2 concentration changes over time during human respiration. In one embodiment, the CO2 module 20 releases CO2 in a manner that releases CO2 for 3 seconds and then stops for 2 seconds. After release, the CO2 automatically diffuses outward, forming a CO2 gradient field that strongly attracts mosquitoes. Mosquitoes are extremely sensitive to changes in CO2 concentration and will instinctively follow paths with higher CO2 concentrations, flying towards the CO2 module 20.

[0041] The distribution, aperture, or opening sequence of the CO2 release holes 29 can be set according to the diffusion direction and rate of CO2 in the preset mosquito-attracting area. The rate and timing of CO2 release by the CO2 module 20 can be adjusted according to one or more of the following environmental parameters: time, temperature, humidity, ambient CO2 concentration, wind direction, light intensity, mosquito activity patterns, carbon capture efficiency, and energy consumption.

[0042] In some embodiments, multiple sensors, such as temperature sensors, humidity sensors, and CO2 concentration sensors, can be set in the surrounding environment to detect relevant parameters in real time. In some embodiments, a nano-sensor array is set in the surrounding environment, which can not only detect the CO2 concentration in the air, but also detect chemical signals that mosquitoes are sensitive to, such as volatile organic compounds (VOCs), lactic acid, and ammonia emitted by the human body.

[0043] The attractant module 30 can be one or more of the following: a light attractant, a heat attractant, and a odor attractant module. The light attractant module utilizes the phototaxis of insects to further attract them, attracting phototactic flying insects such as moths, beetles, and midges. The heat attractant module simulates human body temperature for further attraction. The odor attractant module simulates human body odor for further attraction. All attractant modules are arranged close to the CO2 module 20, so that after mosquitoes are attracted to the CO2, they are further guided by the light attractant, heat attractant, and / or odor attractant.

[0044] In one embodiment, the attractant module 30 includes a light attractant module 32 and an odor attractant module 34. The light attractant module 32 is an ultraviolet (UV) lamp, and the wavelength of the light it produces is in the range of 365-395 nm. Since mosquitoes' visual system is particularly sensitive to ultraviolet light around 365 nm, the wavelength of the UV lamp is preferably 365 nm. In some embodiments, a UV lamp with a wavelength of 395 nm can also be used, which offers better cost-effectiveness and is more suitable for home use.

[0045] The odor attractor module 34, located below the light attractor module 32, releases a special odor that mimics human sweat (containing lactic acid, octenol, etc.), which is highly attractive to various mosquitoes (especially Aedes aegypti), further increasing the trapping rate. Simultaneously, each of the modules generates heat during operation. For example, during the heating process of the CO2 module 20's heating unit 23, some heat is conducted to the outer casing 80, raising its temperature to nearly 50°C, thus simulating human body temperature and convincing mosquitoes that there is "prey" ahead. In some embodiments, a separate heat attractor module can also be used to simulate human body temperature.

[0046] The airflow module 40 includes a fan. Once mosquitoes are attracted to the vicinity of the fan's inlet, the forced airflow generated instantly sucks them in and blows them to the capture module 50, preventing the attracted mosquitoes from escaping. In the illustrated embodiment, the airflow module 40 is an axial flow fan with its inlet facing downwards and its outlet facing upwards. When started, it forms an upward airflow, effectively preventing mosquitoes from escaping by utilizing their tendency to take flight upwards.

[0047] Preferably, the airflow module 40 and the CO2 module 20 are spatially separated to prevent CO2 gas from being drawn away by the airflow module 40 during the release process. For example, the release hole 29 of the CO2 module 20 can be located on the lower outer side of the airflow module 40. Due to its own gravity, the CO2 will sink downwards as it diffuses outwards, so the airflow paths of the two modules will not interfere with each other.

[0048] Preferably, the odor attractor module 34 is disposed on the top of the outer casing 80, the light attractor module 32 is located directly above the odor attractor module 34 and spaced at a certain distance, and the airflow module 40 is located directly above the light attractor module 32. The airflow module 40 forms an upward airflow, and the light attractor module 32 is located in the center below the fan, in an area where the fan suction is strong. After attracting surrounding mosquitoes, the mosquitoes are carried upward with the airflow into the capture module 50.

[0049] like Figure 4As shown, a support frame 70 is provided above the outer casing 80. The support frame 70 includes a frame-shaped support base 72 and multiple support feet 74 extending from the support base 72 toward the top of the outer casing 80. The light source module 32 and the airflow module 40 are both fixed on the support frame 70. The support feet 74 extend downward from the outer edge of the support base 72 and surround the light source module 32 and the airflow module 40. Preferably, the inner wall of each support foot 74 is arc-shaped, which plays a certain guiding role in the airflow of the airflow module 40.

[0050] Each support leg 74 has a CO2 release hole 29 on its outer wall. The CO2 release hole 29 is relatively close to the odor inducing module 34 and far from the support base 72, and its height is lower than the air inlet of the fan of the airflow module 40. In this way, the CO2 emission is not affected by the airflow module 40. In the illustrated embodiment, the support leg 74 forms a guide ring wall 28 around the CO2 release hole 29, which is inclined downwards to further avoid the interference of the airflow module 40 on the CO2 emission. For a specific embodiment of this application, see the simulation diagram of CO2 emission. Figure 9 As can be seen, after CO2 is released, it diffuses towards the outside of the support foot 74 while showing a clear downward flow trend. The upward airflow of the airflow module 40 is mainly inside the support foot 74. The two do not interfere with each other, which ensures both the CO2 emission effect and the fan effect.

[0051] The capturing module 50 includes a mosquito storage chamber 52 fixed to the support base 72. The bottom of the mosquito storage chamber 52 is connected to the air outlet of the fan of the airflow module 40. After being blown into the mosquito storage chamber 52, mosquitoes die from dehydration due to their inability to escape for an extended period. The mosquito storage chamber 52 is preferably a detachable structure. After a predetermined period of use, such as one week, the user can remove it for cleaning to maintain optimal mosquito-catching efficiency. In some embodiments, an electric shock net can also be installed in the mosquito storage chamber 52 to kill the captured mosquitoes by electric shock.

[0052] Preferably, the top of the mosquito storage chamber 52 is connected to a flip-up cover 54, allowing the user to open the cover 54 to remove dead mosquitoes from the chamber, thus reducing the frequency of disassembling and cleaning the chamber. Preferably, the periphery of the mosquito storage chamber 52 has numerous small holes 56. The number, size, and distribution of these holes 56 are such that they facilitate the airflow from the airflow module 40 while preventing mosquitoes from escaping.

[0053] The control module 60 is configured to dynamically adjust the operating parameters of the CO2 module 20, the induction module 30, and the airflow module 40 based on environmental parameters. Figure 4As shown, the control module 60 is fixed in the housing 80 and includes a microcomputer unit and a wireless communication module. The wireless communication module communicates with the sensor to obtain environmental parameters, and the microcomputer unit calculates and adjusts the operating parameters of the CO2 module 20, the induction module 30 and the airflow module 40 based on the environmental parameters fed back by the sensor.

[0054] For example, the control module 60 adjusts the rate at which the CO2 module 20 releases CO2 based on environmental parameters, including one or more of time, temperature, humidity, or ambient CO2 concentration; or, the control module 60 automatically adjusts the rhythm and / or airflow intensity of the CO2 release by the CO2 module 20 based on feedback from the intensity of mosquito activity or the number of mosquitoes captured in the surrounding environment. Of course, the control module 60 can also adjust the rate at which the CO2 module captures CO2, the CO2 release mode, the mosquito-attracting signal strength of the attractant module 30, and the airflow speed and flow rate of the airflow module 40, etc., to achieve the best overall effect. Furthermore, the wireless communication module enables the mosquito trapping system of this application to network with other devices, achieving collaborative operation and data sharing.

[0055] Based on the aforementioned mosquito trapping system, this application also provides a mosquito trapping method, comprising the following steps: constructing a CO2 concentration gradient field in a preset mosquito-attracting area to attract mosquitoes over a larger range (e.g., within a radius of 100 meters); superimposing a light-inducing field, a heat-inducing field, and / or an odor-inducing field to form near-field guidance, further attracting mosquitoes; and forming a directional airflow to guide the attracted mosquitoes to a predetermined location, such as blowing them into the mosquito storage chamber 52 of the trapping module 50. The CO2 concentration gradient field can be formed by periodically releasing CO2, which is derived from the surrounding ambient air, making the operation convenient and cost-effective overall.

[0056] In the illustrated embodiment, a battery 86 is housed inside the outer casing 80. The battery 86 is electrically connected to various electronic components in the system, such as the control module 60, the fan of the airflow module 40, the fan 22 of the CO2 module 20, the heating element 234, and the drive motors of the various air valves 90, 92, and 94, to provide power. The top of the outer casing 80 also features a display screen 88 and multiple operation buttons 89. Users can use the operation buttons 89 to set relevant system parameters and issue operation commands. The display screen 80 can show the overall system's operating status and various relevant parameters of the surrounding environment, allowing users to easily understand the device's usage and mosquito capture status.

[0057] This mosquito trapping system and method utilizes a CO2 module 20 to establish a CO2 concentration gradient field and a lure module 30 to establish a light, heat, and / or odor induction field, simulating human respiration to attract mosquitoes. Simultaneously, an airflow module 40 rapidly blows the attracted mosquitoes to a capture module 50. The mosquitoes, unable to escape within the capture module 50, dehydrate and die, thus completing the trapping and killing process. This application, through the coordinated operation of multiple modules, constructs a CO2 concentration field, a light, heat, and / or odor induction field, and a directional airflow field within a pre-defined mosquito-attracting area, forming a synergistic multi-physics induction environment. This guides mosquitoes along a predetermined path into the capture module 50, significantly improving mosquito-attracting efficiency and improving the surrounding environment.

[0058] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
