Description

Technical Field

[0001] This application relates to the field of vector-borne disease monitoring technology, and in particular to a capture component and vector-borne disease trapping device. Background Technology

[0002] Monitoring disease vectors is crucial for disease prevention and control. Traditional techniques utilize traps to capture disease vectors and then identify them through image analysis to obtain information such as species, physiological characteristics, and status, thus achieving the goal of monitoring disease vectors. These techniques typically use traps to attract target organisms, such as mosquitoes or flies, and capture images for automatic identification.

[0003] In related methods, the disease vectors move within the trapping device, and the images captured by the camera are often dynamic, resulting in blurry images, loss of detail, and low recognition accuracy, which urgently needs improvement. Utility Model Content

[0004] Therefore, it is necessary to provide a capture component and a vector-trapping device to address the above problems.

[0005] This application provides a capture assembly, comprising a shell component, a flipping component, an image acquisition module, and a negative pressure generator. The shell component has a collection channel and an inlet channel. A region of the circumferential wall of the collection channel communicates with the inlet channel, while other regions are closed. The inlet channel is used to connect to the external environment. The flipping component includes a flap, a driving component, and a first trigger. The flap is rotatably disposed on the shell component to open and close the port of the collection channel. The flap has a through hole for the collection channel to communicate with the outside. The driving component is connected to the flap. The first trigger is disposed on the shell component and has a spring and a contact. When the flap is in the closed position, the flap compresses the spring and abuts against the contact, causing the contact to move to a state that triggers the first trigger. The image acquisition module is disposed at the end of the collection channel away from the flap and is used to acquire an image at the flap. The negative pressure generator communicates with the collection channel through the port at the end where the flap is located and is used to generate negative pressure within the collection channel.

[0006] In one embodiment, the casing component includes a connecting pipe and a housing. At least a portion of the inlet channel and at least a portion of the collection channel are formed within the connecting pipe. The connecting pipe is connected to the housing, and the collection channel communicates with the inner cavity of the housing. The capture assembly further includes an insect collection box disposed within the housing and having an opening facing the collection channel. A second through hole is provided through the bottom of the insect collection box, and the negative pressure generator communicates with the collection channel from the side of the insect collection box away from the collection channel via the second through hole.

[0007] In one embodiment, the acquisition channel is connected to the inner cavity of the housing via the top wall of the housing, the flap is rotatably disposed on the top wall of the housing, the first trigger is disposed on the top wall of the housing, and the uncompressed spring extends into the inner cavity of the housing.

[0008] In one embodiment, the connecting pipe includes a first pipe section and a second pipe section. The first pipe section is used to form at least a portion of the acquisition channel, and the second pipe section is used to form at least a portion of the inlet channel. The first pipe section and the second pipe section are integrally formed to allow the acquisition channel and the inlet channel to be continuously connected.

[0009] In one embodiment, the first tube has a first end and a second end disposed opposite to each other, the acquisition channel extends between the first end and the second end, the image acquisition module is disposed at the first end, the flap is used to close and open the port of the acquisition channel at the second end, and a side hole is provided in the area of ​​the first tube between the first end and the second end, the side hole being connected to the inlet channel.

[0010] In one embodiment, the size of the acquisition channel gradually decreases in at least one direction perpendicular to its extension direction in the direction from the first end to the second end.

[0011] In one embodiment, the capture component further includes an aspiration medium supply module, and the connecting tube further includes an aspiration tube connected to the end of the second tube away from the first tube, allowing the second tube to communicate with the external environment; the aspiration tube includes an interface and an injection tube, the injection tube passing through the peripheral wall of the interface, the input end of the injection tube being outside the interface for communicating with the aspiration medium supply module, the output end of the injection tube for outputting the aspiration medium, and the interface having an aspiration port communicating with the outside.

[0012] In one embodiment, the interface is configured in a trumpet shape, and the inner wall of the side where the suction port is located has a larger cross-sectional dimension.

[0013] In one embodiment, the output end extends out of the interface via the suction port.

[0014] In one embodiment, the capture assembly further includes a cleaning component disposed within the housing and movably disposed in a direction intersecting the extension direction of the collection channel; the flap includes a first side and a second side disposed opposite to each other, the first side facing the collection channel when the flap is in the closed position, and the first side facing the cleaning component when the flap is in the open position.

[0015] In one embodiment, the projection of the rotation axis of the flap onto the length of the acquisition channel is located outside the port of the acquisition channel.

[0016] In one embodiment, the extension direction of the acquisition channel intersects the extension direction of at least a portion of the inlet channel, and the inner wall of the acquisition channel is smoothly connected to the inner wall of the inlet channel.

[0017] In one embodiment, the flipping component further includes a second trigger that is activated when the flip panel is in the open position.

[0018] This application also provides a vector-borne disease trapping device, which includes the trapping components described above.

[0019] In the aforementioned capture assembly, the collection channel and the introduction channel are connected, allowing the assembly to communicate with the external environment. A flap is located at one end of the collection channel. When the flap closes the port of the collection channel, a negative pressure generator can connect to both the collection channel and the introduction channel through the first through-hole of the flap, creating a negative pressure within them. This causes pathogenic organisms from the external environment to be drawn into the capture assembly. Because the flap closes the port of the collection channel at this time, the inhaled pathogenic organisms can be adsorbed and fixed to the flap under the negative pressure. Therefore, the image acquisition module can acquire images of the relatively static pathogenic organisms at the flap, resulting in clearer images and facilitating image recognition.

[0020] Furthermore, the image acquisition module is located at the end of the acquisition channel furthest from the flap, and the introduction channel is connected to the acquisition channel through its circumferential wall. Therefore, the introduction channel does not occupy the area at both ends of the acquisition channel or its internal space, allowing the image acquisition module to acquire images of the flap without obstruction. Moreover, because the inner circumferential wall of the acquisition channel is enclosed (except where it connects to the introduction channel), the negative pressure within the acquisition channel does not leak, allowing it to concentrate on the pathogenic organisms within the acquisition channel, effectively adsorbing and fixing them to the flap, thus improving the clarity of the images acquired by the image acquisition module.

[0021] Furthermore, the flipping component is equipped with a first trigger to detect the closed position of the flip plate. When the flip plate abuts against the contact to trigger the first trigger, it also needs to simultaneously provide the clamping force of the compression spring. In other words, when closing the port of the acquisition channel, the flip plate not only needs to provide the covering force, but also the clamping force of the compression spring, so that there is a certain preload between the flip plate and the bracket, reducing the risk of the flip plate loosening under the influence of negative pressure in the acquisition channel.

[0022] In this application, by configuring the inner ring circumferential wall of the collection channel to be closed, and with the pre-tightening clamping effect of the flap, the stability of the pathogenic organisms in the collection channel during negative pressure adsorption can be improved, and the clarity of the images acquired by the image acquisition module can be improved.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] One embodiment of this application provides a vector-borne disease trapping device. This device is used to capture vector organisms and perform image recognition on them to obtain information about them. Vector organisms may include, but are not limited to, mosquitoes, flies, sandflies, black flies, tsetse flies, fleas, lice, ticks, chiggers, scabies mites, dust mites, meal cockroaches, and booklice. The information obtained may include, for example, the species of the vector organism and key physiological characteristics (such as the sex of the mosquito).

[0037] In one embodiment, the vector-borne disease trapping device includes a trapping component for trapping vectors and acquiring images of them for analysis to obtain their biological information. Further, the device also includes a housing (not shown, the same below), within which the trapping component is housed. The housing provides protection for the trapping component, facilitating the application of the device in outdoor settings. Moreover, the vector-borne disease trapping device can be applied in the following scenarios: densely populated public places, food production-storage-sales chains, urban sanitation nodes, and green spaces and waterways (such as parks, street gardens, and greenways).

[0038] Please see Figures 1 to 4 , Figure 1 An isometric schematic diagram of a capture component provided in one embodiment of this application is shown. Figure 2 for Figure 1 The top view of the captured component is shown. Figure 3 for Figure 2 A cross-sectional view of the capture component along line AA. Figure 4 for Figure 3 A magnified view of a portion of point B in the capture assembly shown. An embodiment of this application provides a capture assembly 10 including a shell component 100, a flipping component 200, an image acquisition module 300, and a negative pressure generator (not shown, the same below). The shell component 100 has capture channels (i.e., the acquisition channel 101 and the introduction channel 102 mentioned below). The negative pressure generator is used to create negative pressure within the capture channels to guide external vector organisms into the capture channels for the image acquisition module 300 to centrally acquire images.

[0039] The casing component 100 includes a collection channel 101 and an inlet channel 102. A region of the circumferential wall of the collection channel 101 is connected to the inlet channel 102, while other regions are enclosed. The inlet channel 102 is used to connect to the external environment. That is, the collection channel 101 can be connected to the external environment through the inlet channel 102.

[0040] The flipping component 200 includes a flip plate 210 and a first trigger 230. The triggering state of the first trigger 230 can be used to determine the position of the flip plate 210. The flip plate 210 is rotatably disposed on the housing component 100 to open and close the port of the acquisition channel 101, that is, the flip plate 210 is rotatably located at one end of the acquisition channel 101. The flip plate 210 is provided with a first through hole 211 for communicating between the acquisition channel 101 and the outside. The image acquisition module 300 is disposed at the end of the acquisition channel 101 away from the flip plate 210, and is used to acquire the image at the flip plate 210. The negative pressure generator is connected to the acquisition channel 101 through the port at the end where the flip plate 210 is located, and is used to generate negative pressure in the acquisition channel 101.

[0041] In this application, since the flap 210 is located at one end of the collection channel 101, when the flap 210 closes the port of the collection channel 101, the negative pressure generator can communicate with the collection channel 101 and the introduction channel 102 through the first through hole 211 of the flap 210 to create a negative pressure in the collection channel 101 and the introduction channel 102, so that the vector organisms in the external environment are sucked into the capture component 10. Since the flap 210 closes the port of the collection channel 101 at this time, the sucked vector organisms can be adsorbed and fixed on the flap 210 under the action of negative pressure. Therefore, the image acquisition module 300 can acquire an image of the relatively static vector organisms at the flap 210, making the acquired image clearer and facilitating image recognition.

[0042] Furthermore, the image acquisition module 300 is located at the end of the acquisition channel 101 furthest from the flap 210, and the introduction channel 102 is connected to the acquisition channel 101 through the circumferential wall of the acquisition channel 101. Therefore, the introduction channel 102 does not occupy the area at both ends of the acquisition channel 101 or the internal space, and the image acquisition module 300 can acquire images at the flap 210 without obstruction through the acquisition channel 101. In addition, since the inner circumferential wall of the acquisition channel 101 is closed (except for the part connected to the introduction channel 102), the negative pressure effect in the acquisition channel 101 does not leak, and can be concentrated on the pathogenic organisms in the acquisition channel 101, so that they are effectively adsorbed and fixed to the flap 210, thereby improving the clarity of the images acquired by the image acquisition module 300.

[0043] In one embodiment, a first trigger 230 is disposed on the housing component 100, and the first trigger 230 has a spring 231 and a contact 232. When the flap 210 is in the closed position, the flap 210 compresses the spring 231 and abuts against the contact 232, causing the contact 232 to move to a state that triggers the first trigger 230. That is, when the flap 210 triggers the first trigger 230 by abutting against the contact 232, it also needs to simultaneously provide a clamping force to compress the spring 231. In other words, when closing the port of the acquisition channel 101, the flap 210 not only needs to provide a covering force, but also needs to provide a clamping force to compress the spring, so that there is a certain preload between the flap 210 and the bracket, reducing the risk of the flap 210 loosening under the influence of negative pressure in the acquisition channel 101.

[0044] Furthermore, when the flap 210 opens the port of the acquisition channel 101, the pathogens in the acquisition channel 101 can flow out of the acquisition channel 101 through the port under negative pressure, thereby cleaning the acquisition channel 101 and reducing the problem of continuous accumulation of pathogens in the acquisition channel 101 that affects image acquisition.

[0045] In this application, by configuring the closed setting of the collection channel 101, combined with the pre-tightening clamping effect of the flip plate 210, the stability of the pathogenic organisms in the collection channel 101 during negative pressure adsorption can be improved, and the clarity of the images acquired by the image acquisition module 300 can be improved.

[0046] Please refer to it again. Figure 1 In one embodiment, the flipping assembly further includes a drive member 220 connected to the flap 210 to drive the flap 210 to rotate, switching the flap 210 between an open position and a closed position. That is, the drive member 220 provides a closing force to the flap 210 and a clamping force to compress the spring. It should be noted that, regarding only the clamping force of the spring, the driving force provided by the drive member 220 is often not exactly equal to the clamping force, but is usually greater. That is, at this time, the drive member 220 will provide a clamping force to the flap 210 that is slightly greater than the clamping force, so that the flap 210 fits tightly against the end wall of the collection channel 101 (the end wall of the second end 112 mentioned below). Therefore, when the flap 210 is in the closed position, the sealing of the end of the collection channel 101 is better, reducing the risk of pathogens escaping from the collection channel 101 through gaps. In short, the first trigger 230 configured in this application is used to detect the position of the flap 210. On the one hand, this ensures that the flap 210 is accurately in the closed position. On the other hand, the first trigger 230 has a spring 231, which means that the driving member 220 always needs to provide a clamping force to the flap 210 that is slightly greater than the aforementioned clamping force. This clamping force exceeding the clamping force can improve the tightness of the flap 210 in closing the port of the acquisition channel 101. Simultaneously, when any factor causes the flap 210 to loosen, the trigger state of the first trigger 230 will change. At this time, the driving member 220 will further drive the flap 210 to rotate, thus restoring it to the state where the clamping force is slightly greater than the clamping force.

[0047] Compared to the traditional method of closing the flap 210 by rotating it at a preset angle, the present application can significantly improve the tightness and stability of the flap 210's closure by configuring the first trigger 230.

[0048] As one example, the drive unit 220 can be configured as a stepper motor to accurately control the clamping force.

[0049] In one embodiment, the vector-borne disease trapping device further includes a central controller. The drive unit 220 is connected to the central controller, which controls the clamping force provided by the drive unit 220 as described above, ensuring a desired clamping degree between the flap 210 and the end wall of the collection channel 101. Furthermore, the central controller has a communication module that allows it to communicate with a server. Thus, the server can update and upgrade the central controller using Over-the-Air Technology (OAT), enabling it to control the drive unit 220 to provide different clamping forces to adapt to various environments. For example, compared to indoor environments, when the vector-borne disease trapping device is used in outdoor environments (with more external interference), the flap 210 can have a relatively greater tightness with the end wall of the collection channel 101.

[0050] Please see Figure 5 Combined Figure 1 and Figure 3 In one embodiment, the casing component 100 includes a connecting pipe 103 and a housing 104. At least a portion of the inlet channel 102 and at least a portion of the collection channel 101 are formed within the connecting pipe 103. The connecting pipe 103 is connected to the housing 104, and the collection channel 101 communicates with the inner cavity of the housing 104. When the flap 210 is opened, the pathogenic organisms in the collection channel 101 can be collected and discharged into the inner cavity of the housing 104. Simultaneously, the housing 104 can also provide installation space for the body of the negative pressure generator or its connecting pipes.

[0051] In one embodiment, the acquisition channel 101 communicates with the inner cavity of the housing 104 via the top wall of the housing 104, and the flap 210 is rotatably disposed on the top wall of the housing 104, thereby relatively simplifying the structure of the connecting pipe 103. The first trigger 230 is disposed on the top wall of the housing 104, and the uncompressed spring 231 extends into the inner cavity of the housing 104 for the flap 210 to press against it.

[0052] Please see Figure 5 Combined Figure 4 In one embodiment, a first window 141 is provided on the top of the housing 104, the body of the first trigger 230 is located outside the housing 104, and the spring 231 extends into the inner cavity of the housing 104 through the first window 141 for the flap 210 to hold.

[0053] Please continue reading. Figure 3 In one embodiment, the flipping component 200 further includes a second trigger 240, which is triggered when the flap 210 is in the open position. Thus, the first trigger 230 and the second trigger 240 work together to accurately detect the flipping position of the flap 210.

[0054] Please continue reading. Figure 5 Combined Figure 3 In one embodiment, the first tube 110 has a first end 111 and a second end 112 disposed opposite to each other, and a data acquisition channel 101 extends between the first end 111 and the second end 112. An image acquisition module 300 is disposed at the first end 111, and a flap 210 is used to close and open the port of the data acquisition channel 101 at the second end 112. A side hole 113 is provided in the region of the first tube 110 located between the first end 111 and the second end 112, and the side hole 113 communicates with the inlet channel 102. Thus, the image acquisition module 300 located at the first end 111 can capture images of the flap 210 located at the second end 112 without obstruction.

[0055] Furthermore, in the direction from the first end 111 to the second end 112, the size of the acquisition channel 101 gradually decreases in at least one direction perpendicular to its extension direction. That is, the length and / or width of the cross-section of the acquisition channel 101 gradually decreases to form a conical tube with a relatively thick first end 111 and a relatively thin second end 112, thereby facilitating the guidance of disease vectors within the acquisition channel 101 to converge towards the second end 112 (i.e., the end where the flap 210 is located), and facilitating the image acquisition module 300 to centrally acquire images.

[0056] It is understandable that the inner circumferential wall of the collection channel 101 is sealed, that is, the inner circumferential wall of the first tube 110 is sealed. In this way, not only can the negative pressure guidance intensity within the collection channel 101 be improved, but since there are no uneven parts such as openings or grooves, it can also improve the smoothness of the conical tube guiding the disease vector.

[0057] Please see Figure 3 and Figure 5 In one embodiment, the extension direction of the collection channel 101 intersects the extension direction of at least a portion of the introduction channel 102, and the inner wall of the collection channel 101 is smoothly connected to the inner wall of the introduction channel 102 to improve the smoothness of gas flow in the capture channel and facilitate the guidance of disease vectors to be concentrated at the flap 210.

[0058] Please see Figure 3 Combined Figure 5In one embodiment, the capture component 10 further includes an insect collection box 400, which is disposed in the housing 104 and is used to collect disease vectors discharged into the housing 104 by the collection channel 101. The insect collection box 400 has an opening 410 facing the collection channel 101, and a second through hole 420 is provided through the bottom of the insect collection box 400. A negative pressure generator is connected to the collection channel 101 from the side of the insect collection box 400 away from the collection channel 101 through the second through hole 420. It is understood that the second through hole 420 allows a negative pressure medium (e.g., a suction airflow) to pass through and blocks disease vectors. Based on the positional relationship between the negative pressure generator and the insect collection box 400, under the guidance of negative pressure, the disease vectors discharged from the collection channel 101 will first pass through the insect collection box 400 and be intercepted by the insect collection box 400 and collected in the insect collection box 400, thereby achieving the collection of disease vectors.

[0059] It should be noted that traditional negative pressure generators are usually configured as fans, etc., and the bodies of disease vectors are easily broken when they pass through the negative pressure generator. In the capture assembly 10 provided in this embodiment, the disease vectors discharged from the collection channel 101 can be directly collected into the insect collection box 400 under the guidance of negative pressure without passing through the negative pressure generator. Therefore, the integrity of the disease vector's body can be maintained to the greatest extent, which facilitates the recovery and reanalysis of the disease vector.

[0060] Please see Figure 5 In one embodiment, the collection channel 101 is arranged along a reference direction S, i.e., the first end 111 points to the second end 112 along the reference direction S. Along the reference direction S, the inner cavity of the housing 104 sequentially includes a movable cavity 140, a collection cavity 150, and a mounting cavity 160, wherein the flap 210 can rotate within the movable cavity 140, and the insect collection box 400 is disposed within the collection cavity 150. The mounting cavity 160 is for mounting a negative pressure generator, or the mounting cavity 160 is connected to the pipeline of the negative pressure generator. Thus, within the housing component 100, the pathogenic organisms, guided by negative pressure, always tend to move towards the location of the mounting cavity 160.

[0061] Please continue reading. Figure 5 Combined Figure 3 In one embodiment, as described above, the housing 104 has a collection chamber 150, and the cavity wall of the collection chamber 150 has an outlet 151. The insect collection box 400 is movably disposed in the collection chamber 150, so the insect collection box 400 can be pushed and pulled to enter or exit the collection chamber 150 through the outlet 151.

[0062] In one embodiment, the inner wall of the box 104 has a protruding annular platform 170, and the insect collection box 400 is placed on the annular platform 170 and stably positioned within the collection chamber 150.

[0063] Please see Figure 3In one embodiment, the projection of the rotation axis O of the flap 210 along the length of the collection channel 101 is located outside the port of the collection channel 101. Thus, when the flap 210 is in the open position, the port of the collection channel 101 can be fully opened, allowing the collection channel 101 to smoothly discharge pathogens.

[0064] Please see Figure 3 and Figure 4 Combined Figure 5 In one embodiment, the capture component 10 further includes a cleaning component (not shown, the same below), which is disposed inside the housing 104 and is used to clean the flip plate 210. This, on the one hand, causes disease vectors that may be attached to the flip plate 210 to detach from the flip plate 210 and fall into the housing 104, reducing the risk of disease vectors accumulating at the flip plate 210 and thus limiting the accuracy of repeated image acquisition by the image acquisition module 300. On the other hand, this arrangement reduces the risk of dust and dirt entering the acquisition channel 101 along with disease vectors accumulating at the flip plate 210 and thus limiting the accuracy of image acquisition.

[0065] Furthermore, the cleaning component is positioned along the direction intersecting the extension direction of the collection channel 101 (see...). Figure 3 The component (L) is movably configured so that the cleaning component can avoid the flipping space of the flap 210. The flap 210 includes a first surface 212 and a second surface 213 arranged opposite to each other. When the flap 210 is in the closed position, the first surface 212 faces the acquisition channel 101, that is, the image acquisition module 300. When the flap 210 is in the open position, the first surface 212 faces the cleaning component. At this time, the cleaning component can be used to clean the first surface 212, reducing the risk of pathogens and dirt accumulating on the first surface 212.

[0066] Please see Figure 3 and Figure 4 In one embodiment, the capture component 10 further includes an avoidance actuator (not shown, the same below) connected to the cleaning component to drive the cleaning component to move in a direction intersecting the extension direction of the collection channel 101 to avoid the activity space of the flap 210 and to approach the flap 210 to clean the first surface 212.

[0067] Furthermore, the cleaning component and the avoidance actuator can be located within the active cavity 140.

[0068] As one example, a cleaning component can be configured as a brush or other component with cleaning capabilities.

[0069] Please see Figure 3 and Figure 5In one embodiment, a second trigger 240 is also disposed within the housing 104. The triggering state of the second trigger 240 can be used to determine whether the flap 210 has accurately reached the open position, providing a reference for the movement of the cleaning component.

[0070] Furthermore, the second trigger 240 and the cleaning component can be disposed on opposite sides of the cavity wall of the active cavity 140.

[0071] like Figure 5 In one embodiment, a second window 142 is provided on the side wall of the housing 104, and a second trigger 240 is provided through the second window 142, so that part of its structure extends into the housing 104 for the flap 210 to hold.

[0072] As one example, the first trigger 230 can be configured as a micro switch or other limiter with a reed 231. Similarly, the first trigger 230 can be configured as a limiter such as a micro switch.

[0073] Please see Figure 5 In one embodiment, the connecting pipe 103 includes a first pipe portion 110 and a second pipe portion 120. The first pipe portion 110 forms at least a portion of the collection channel 101, and the second pipe portion 120 forms at least a portion of the introduction channel 102. The first pipe portion 110 and the second pipe portion 120 are integrally formed, allowing the collection channel 101 and the introduction channel 102 to be continuously connected, i.e., the collection channel 101 and the introduction channel 102 are seamlessly connected, thereby improving the smoothness of airflow and simplifying the structure.

[0074] Please see Figure 3 , Figure 5 and Figure 6 In one embodiment, the capture component 10 further includes an attraction medium supply module 20, which supplies attraction medium to the introduction channel 102. Further, the output of the attraction medium supply module 20 can be located near the end of the introduction channel 102 that connects to the external environment. In this case, disease vectors attracted by the attraction medium can be drawn into the capture component 10 by the negative pressure at the port of the introduction channel 102 and ultimately enter the collection channel 101.

[0075] Understandably, the attraction medium provided by the attraction medium supply module 20 can be specifically adjusted according to the disease vector organisms that the capture component 10 expects to trap. As one example, when the capture component 10 is configured to trap mosquitoes, the attraction medium can be configured as carbon dioxide to attract mosquitoes by mimicking biological respiration. In this case, the attraction medium supply module 20 can be configured as a carbon dioxide supply module.

[0076] Please see Figure 6 Combined Figure 3 and Figure 5 In one embodiment, the connecting tube 103 further includes a suction tube 130, which is connected to the end of the second tube 120 away from the first tube 110 and allows the second tube 120 to communicate with the external environment. The suction medium supply module 20 is connected to the inlet channel 102 at the suction tube 130, so that the suction medium is distributed at the inlet (i.e., the suction port 131a mentioned below) where the suction tube 130 communicates with the outside, so that the disease vector organisms attracted by the suction medium can be directly and effectively attracted into the channel 102.

[0077] Please see Figure 6 Combined Figure 2 The suction tube 130 includes an interface 131 and an injection tube 132. The interface 131 has a suction port 131a communicating with the outside. The injection tube 132 passes through the peripheral wall of the interface 131, such that one end of the injection tube 132 is located outside the interface 131, and at least a portion of the other end is located inside the interface 131. The input end 132a of the injection tube 132 is outside the interface 131 and is used to communicate with the suction medium supply module 20. The output end 132b of the injection tube 132 is used to output the suction medium, and at least a portion of the output end 132b is located inside the interface 131. Therefore, the suction medium supplied thereto diffuses from inside the interface 131 to the outside through the suction port 131a. As a result, pathogenic organisms attracted by the suction medium gather at the suction port 131a and can be directly and effectively sucked into the interface 131.

[0078] The output end 132b extends outward from the interface member 131 via the suction port 131a. Thus, the suction medium output from the output end 132b can diffuse outward from the interface member 131 to effectively attract pathogenic organisms. Figure 5 The suction medium output from the output end 132b can flow in an annular manner under the negative pressure at the suction port 131a (see reference numeral Q) to fully attract pathogenic organisms, and then flow back into the interface 131 under the negative pressure.

[0079] In one embodiment, the number of injection fittings 132 can be multiple.

[0080] In one embodiment, the interface 131 is configured in a funnel shape, and the inner wall of the side where the suction port 131a is located has a larger cross-sectional dimension in order to guide the pathogenic organisms in.

[0081] In one embodiment, the second tube 120 may be configured as a bend to adjust the orientation of the interface 131 as needed to facilitate the attraction of disease vectors.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
