Description

Technical Field

[0001] This utility model relates to the field of disease control technology, and in particular to a fly bait storage device. Background Technology

[0002] Flies and other dipteran insects are important vectors for many infectious diseases. In the field of disease prevention and control, monitoring and collecting fly density in specific environments is a fundamental task for assessing epidemic risk, cutting off transmission routes, and formulating prevention and control strategies. Existing fly monitoring and capture usually uses trapping devices. The working principle is mainly to place chemical attractants inside the device, which attract flies to the vicinity of the device through the diffusion of odor molecules and by taking advantage of the flies' chemotaxis. When flies are attracted to the bait and enter the inlet, they fall into the collection container inside, thus achieving capture.

[0003] However, existing fly bait storage and capture devices still have some obvious shortcomings in practical use. Traditional devices mostly rely on insects flying in on their own, lacking an active suction mechanism, and lack effective escape prevention structures inside. Live flies that have entered the collection bag can easily fly out in the opposite direction along the insect entry channel, resulting in distorted monitoring data. Secondly, existing collection equipment is usually designed only for flying insects, making it difficult to capture crawling vectors such as ticks, resulting in a single type of sample collected and failing to meet the needs of comprehensive monitoring.

[0004] Therefore, there is an urgent need for a fly bait storage device with a reasonable structure that can prevent sample escape. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art mentioned above, and to propose a fly bait storage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fly bait storage device includes a bait chamber, a connecting plate installed at the bottom of the bait chamber, a groove formed on the surface of the connecting plate, a bait tray installed at the top of the connecting plate, a connecting pipe connected to the bottom of the connecting plate, an installation shell installed on the bottom wall of the connecting pipe, a negative pressure fan installed inside the installation shell, a ventilation chamber installed at the bottom of the connecting pipe, an installation tray connected to the bottom of the ventilation chamber, and a collection chamber at the bottom of the ventilation chamber.

[0007] Preferably, the surface of the bait chamber has slots that are adapted to the size of the ventilation net, and the ventilation net is distributed at equal intervals around the circumference of the surface of the bait chamber.

[0008] Preferably, a support frame is fixedly installed at the top of the bait chamber, and a rainproof plate is fixedly installed at the top of the support frame. The height of the rainproof plate gradually decreases from the center to the edge, and a gap is provided between the rainproof plate and the top of the bait chamber.

[0009] Preferably, the cross-sectional area of ​​the connecting pipe gradually decreases from top to bottom, and the connecting pipe is connected to the interior of the bait chamber through the groove.

The protective cover is in the shape of an inverted cone.

[0011] Preferably, a base plate is fixedly installed at the bottom end of the connecting pipe, and a communication opening is provided on the surface of the base plate. A nylon mesh is fixedly installed at the bottom end of the base plate at the communication opening, and the opening of the nylon mesh gradually decreases as it descends.

[0012] Preferably, a supporting annular plate is fixedly installed at the bottom of the ventilation chamber, and a groove is opened on the surface of the supporting annular plate. The collection chamber is fixedly installed at the bottom of the supporting annular plate, and an inclined part is fixedly installed at the top of the supporting annular plate.

[0014] Compared with the prior art, the present invention provides a fly bait storage device, which has the following beneficial effects: 1. This fly bait storage device, by designing the mounting plate as an induction core that can hold dry ice, effectively attracts ticks and other crawling insects on the ground to slide into the collection chamber at the bottom by utilizing the high density and easy sinking properties of carbon dioxide; in conjunction with the negative pressure fan at the top to actively capture flying insects, it achieves three-dimensional simultaneous capture of flying and crawling vectors, thus solving the problem of existing devices capturing only one target.

[0015] 2. This fly bait storage device uses a naturally closed one-way structure formed by nylon netting to prevent flies from flying out in the opposite direction when the fan stops; at the same time, it uses the inverted geometric structure formed by the inclined part at the top of the collection chamber to prevent ticks from crawling out along the wall; thus achieving the purpose of preventing escape based on the habits of different insects, significantly improving the retention rate of live samples and ensuring the authenticity of monitoring data.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figures 1-4A fly bait storage device includes a bait chamber 1. The surface of the bait chamber 1 has slots adapted to the size of a ventilation mesh 2. The ventilation mesh 2 is evenly spaced around the surface of the bait chamber 1. The ventilation mesh 2 is made of stainless steel, and its mesh diameter is smaller than the volume of a fly, ensuring odor diffusion while preventing direct contact between external organisms and the bait. A connecting plate 5 is installed at the bottom of the bait chamber 1. The surface of the connecting plate 5 has grooves 6. A bait tray 7 is installed at the top of the connecting plate 5. The bait tray 7 is fixed with a snap-fit ​​mechanism for easy replacement of internal chemical attractants or carrion bait. A connecting pipe 8 is connected to the bottom of the connecting plate 5. The bottom wall of the connecting pipe 8 is equipped with an installation shell 9, and a negative pressure fan 10 is installed inside the installation shell 9. A ventilation chamber 16 is installed at the bottom end of the connecting pipe 8, and an installation plate 17 is connected to the bottom end of the ventilation chamber 16. The installation plate 17 can store dry ice to release carbon dioxide to attract ticks. The installation plate 17 is constructed as a hollow cylindrical structure, and its interior forms a cavity for holding dry ice. Several through holes are opened on the top surface of the installation plate 17 to release the carbon dioxide gas generated by the sublimation of dry ice to the surrounding area. A collection chamber 20 is provided at the bottom of the ventilation chamber 16. The collection chamber 20 is made of transparent acrylic material to facilitate observation of the capture situation inside.

[0021] Reference Figures 1-2 A support frame 3 is fixedly installed at the top of the bait chamber 1, and a rainproof plate 4 is fixedly installed at the top of the support frame 3. The height of the rainproof plate 4 gradually decreases from the center to the edge. There is a gap between the rainproof plate 4 and the top of the bait chamber 1. In actual use, in order to facilitate the use of the device in the field, a hanging hook can be fixedly installed at the center of the top of the rainproof plate 4. In addition, a ring-shaped solar panel can be integrated on the upper surface of the rainproof plate 4. A storage battery is installed inside the housing 9. The solar panel can be electrically connected to the storage battery and the negative pressure fan 10 through wires.

[0022] Reference Figures 2-4 The cross-sectional area of ​​the connecting pipe 8 gradually decreases from top to bottom, forming an air-collecting and guiding structure to enhance the flow rate of the intake air. The connecting pipe 8 is connected to the interior of the bait chamber 1 through the groove 6. A motor for driving the negative pressure fan 10 is fixedly installed inside the mounting shell 9. A connecting plate 11 is fixedly installed at the top of the mounting shell 9. A protective cover 12 is fixedly installed at the top of the connecting plate 11. The protective cover 12 is shaped like an inverted cone and can prevent flies from contacting the negative pressure fan 10 and dying. A base plate 13 is fixedly installed at the bottom of the connecting pipe 8. A connecting port 14 is opened on the surface of the base plate 13. A nylon mesh 15 is fixedly installed at the bottom of the base plate 13 at the connecting port 14. The opening of the nylon mesh 15 gradually decreases downward, so that the nylon mesh 15 forms a one-way structure. When the negative pressure fan 10 stops working, the lower opening of the nylon mesh 15 closes naturally to prevent the captured flies from escaping upward.

[0023] Reference Figures 2-3A supporting annular plate 18 is fixedly installed at the bottom of the ventilation chamber 16. The surface of the supporting annular plate 18 has a groove 19. The collection chamber 20 is fixedly installed at the bottom of the supporting annular plate 18. An inclined part 21 is fixedly installed at the top of the supporting annular plate 18. The surface of the inclined part 21 is smooth to prevent insects from climbing and staying inside. A drop groove 22 is opened at the center of the top of the collection chamber 20. The height of the drop groove 22 gradually decreases from the edge of the collection chamber 20 to the center, making it difficult for insects that fall into the collection chamber 20 to climb out backward through the geometric dead angle. The inclined part 21 is inclined so that ticks and other crawling insects can fall into the interior of the collection chamber 20. The mounting plate 17 is detachable. The width of the groove 19 is greater than the diameter of the mounting plate 17. By removing the mounting plate 17 and letting it pass through the groove 19, the mounting plate 17 can be removed and cleaned.

[0024] In this invention, before using the device for trapping operations, the staff must first place chemical attractants or rotten meat as bait in the bait tray 7 inside the bait chamber 1, and at the same time fill dry ice into the receiving cavity inside the mounting plate 17. The through hole on the top surface of the mounting plate 17 is used as a channel for releasing carbon dioxide gas, and the battery power is checked to ensure that the negative pressure fan 10 can start normally.

[0025] At this time, the scent of the bait in the bait tray 7 diffuses to the surrounding environment through the ventilation net 2 on the surface of the bait chamber 1. Attracted by the scent, flies fly to the top of the device and gather in the gap below the rainproof plate 4. At this time, the negative pressure fan 10 is activated, forming a negative pressure airflow in the area of ​​the connecting pipe 8 and the connecting plate 5 above it. The gathered flies are quickly drawn in by the airflow through the groove 6 on the surface of the connecting plate 5 and fall rapidly along the connecting pipe 8 with a gradually decreasing cross-section. During this process, the inverted conical protective cover 12 at the top of the connecting plate 11 can guide the airflow around the motor area to prevent flies from directly hitting the negative pressure fan 10. Subsequently, the flies are blown open by the airflow through the nylon net 15 below the bottom plate 13 and finally fall into the ventilation chamber 16 and are trapped by the wind pressure, thus completing the capture of flying insects.

[0026] Meanwhile, dry ice in the mounting plate 17 at the bottom of the device sublimates to produce carbon dioxide gas, which overflows through the through hole. Since carbon dioxide is denser than air, the gas will pass through the ventilation chamber 16 and the surrounding area of ​​the collection chamber 20, sink downwards, and diffuse along the ground. After sensing the carbon dioxide concentration gradient, ticks and other crawling insects on the ground gather at the bottom of the device and begin to climb. When the ticks crawl to the inclined part 21 at the top of the supporting ring plate 18, because the surface of the inclined part 21 is smooth and has a specific inclination angle, the ticks cannot stand firmly and slip down, falling directly into the collection chamber 20 at the bottom, thereby achieving the trapping of crawling insects.

[0027] When the trapping ends and the negative pressure fan 10 stops working, the bottom of the nylon net 15 is no longer opened by the wind, so its lower opening will close naturally, effectively preventing flies in the ventilation chamber 16 from flying out backwards; while ticks that fall into the collection chamber 20 are limited by the geometric inverted features of the inclined part 21 and have difficulty climbing out; in addition, workers can pass through the slot 19 on the support ring plate 18 to remove the mounting plate 17 for cleaning and maintenance of the device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
