Description

Technical Field

[0001] This utility model relates to a device for collecting small insects in the wild, belonging to the technical field of insect capture devices. Background Technology

[0002] Insect control research involves culturing insects to conduct drug efficacy experiments on them, determining the effectiveness of the drugs in killing insects. This process requires collecting insects and conducting drug experiments in specific containers.

[0003] Generally, small insects are collected using tweezers or soft clamps, but this process easily damages the insects or even kills them before drug experiments, affecting the accuracy of the experiments. Therefore, a more appropriate method of collection should be adopted for small insects. Suction collection has been used in various agricultural research sites, as illustrated in Chinese patent publication CN 214282926. A whitefly suction device for easy visual assessment of insect quantity is disclosed. The technical solution includes connecting the suction shell to an air pump and an air inlet pipe, and utilizing a mesh structure to block the sucked whiteflies, ultimately allowing observation of the sucked whitefly size. However, during implementation, it's evident that while the mesh structure is designed inside the suction shell, this design is difficult to implement in practice. The mesh is a soft material; without perimeter positioning, the edges deform during suction, causing the sucked insects to escape. Furthermore, mesh installation is inconvenient, and replacement after use is equally problematic. Insect experiments typically require large-scale operations, and an inconveniently installed and used suction device significantly hinders experimental progress. Therefore, for drug experiments targeting small insects, a collection device that is easy to install and disassemble, and has high suction efficiency is needed to address the problems existing in the current technology. Summary of the Invention

[0004] Purpose of the invention: In view of the shortcomings of the existing technology, this utility model provides a device for collecting small insects in the wild, so as to solve the problems mentioned in the background art.

[0005] Technical solution: A device for collecting small insects in the wild includes an air pump and an air pump hose connected to the air pump, an intermediate connecting pipe detachably connected to the air pump hose, and a transparent insect collecting tube detachably connected to the intermediate connecting pipe; the insect collecting tube has an opening at its tail end, and a mesh is fixedly installed near one end of the intermediate connecting pipe.

[0006] This invention is used for the suction and collection of small insects, such as thrips and whiteflies. A suction pump provides the suction, and the suction hose allows for operation at various angles. An intermediate connecting tube connects the suction hose and the insect collection tube. The insect collection tube is disposable and needs to be removed and replaced after each collection. Therefore, the insect collection tube and intermediate connecting tube are designed to be detachable. To facilitate the production of the insect collection tube and prevent insect escape, a mesh screen is fixed at the end to prevent insects from escaping. The insect collection tube is transparent, making it easier to observe the number of collected insects and monitor their condition. After each collection, the tail end is sealed.

[0007] The mesh is fixed to the end of the insect collecting tube by an adhesive.

[0008] By using an adhesive such as resin to fix the mesh to the end of the insect collecting tube through curing and bonding, the production method is simple and convenient. At the same time, it can provide a stable adhesion effect, making the mesh less likely to fall off. It also ensures air circulation in the insect collecting tube, reduces accidental insect deaths caused by the closed environment, and makes the results of insect drug experiments more accurate.

[0009] The insect collecting tube is configured with a limiting platform at one end near the middle connecting tube, with an outer diameter larger than the diameter of the insect collecting tube. The middle part of the limiting platform is connected to the insect collecting tube. The inner diameter of the intermediate connecting pipe near the insect collecting tube matches the outer diameter of the limiting platform, and an arc-shaped limiting protrusion is provided on the inner side near the opening of the intermediate connecting pipe. At least two opening slots are also provided on the end of the intermediate connecting pipe near the insect collecting tube, and the depth of the opening slots is greater than the distance between the arc-shaped limiting protrusion and the edge of the intermediate connecting pipe.

[0010] To ensure the stability of the insect collecting tube after assembly with the intermediate connecting tube, and to facilitate disassembly, an arc-shaped limiting protrusion and an open groove are designed. When the insect collecting tube is inserted into the intermediate connecting tube, the elastic deformation property of the plastic material of the intermediate connecting tube causes the limiting platform to spread open at the end of the intermediate connecting tube as it passes the arc-shaped limiting protrusion. After the limiting platform passes the arc-shaped limiting protrusion, the parts on both sides of the open groove rebound inward and converge, so that the arc-shaped limiting protrusion is locked at the bottom edge of the limiting platform, thus achieving the limiting function and facilitating subsequent insect suction operations.

[0011] The limiting platform includes a central protrusion that is integral with the insect collecting tube and a sealing rubber ring that surrounds the upper column of the protrusion. The outer diameter of the sealing rubber ring is the same as the outer diameter of the bottom of the protrusion. The two together form a cylindrical limiting platform. The inner side of the intermediate connecting pipe is provided with at least one arc-shaped sealing protrusion at the position corresponding to the sealing rubber ring after the insect collecting tube is installed.

[0012] To ensure that the suction power generated by the air pump is not affected during operation and to facilitate subsequent adjustment of the suction power, a sealing rubber ring and an arc-shaped sealing convex ring are installed at the connection. After the insect collection tube is installed, the arc-shaped sealing convex ring and the sealing rubber ring are press-fitted to achieve a sealing effect, preventing gas from entering from the edge gaps and affecting the set suction power.

[0013] The insect collecting tube has at least two symmetrically arranged insertion holes at its end near the middle connecting tube. The mesh is pressed and fixed between the end of the insect collecting tube and the pressure plate by a pressure plate with piercing posts on the bottom surface corresponding to the positions of the insertion holes.

[0014] To facilitate the replacement and installation of the mesh, a pressure plate with piercing posts and corresponding insertion holes are set to press the mesh between the two. If the mesh is damaged during use, it can be easily replaced, and it also has the potential for mass production.

[0015] The puncture post is bullet-shaped, with its end cross-section gradually narrowing to resemble a bullet head. The end near the pressure plate is columnar, and its outer diameter matches the inner diameter of the insertion hole.

[0016] To make the insertion of the piercing post more secure and to facilitate the piercing of the mesh, a bullet-shaped piercing post is designed to easily pierce the mesh. At the same time, the columnar structure matches the insertion hole to achieve a tight fit, generating a certain amount of friction to prevent the pressure plate from falling off.

[0017] The edge of the pressure plate away from the insect collecting tube is designed with an arc-shaped chamfer.

[0018] To facilitate smoother installation during assembly, the curved chamfer structure acts as a guide, making installation more convenient.

[0019] The tail end of the insect collecting tube is designed as a bullet shape with a gradually decreasing cross-section, and the opening position is set in any side direction from the apex of the tail end, so that the opening position is in an inclined position.

[0020] To facilitate the suction of insects, the opening is positioned on an angled surface, giving operators a clearer view and making it easier to observe the location of the suction opening during the suction process.

[0021] The middle connecting tube is configured as a connector at the end near the insect collecting tube and as a connecting tube at the end near the air extraction hose. The inner diameter of the connector is larger than the inner diameter of the connecting tube. The arc-shaped limiting protrusion and the arc-shaped sealing protrusion are both located on the inner side of the connector.

[0022] To facilitate identification during installation, the intermediate connecting pipe is divided into two parts with different diameters. At the same time, the connector with a larger inner diameter has an internal structure that is easier to manufacture, thus reducing production costs.

[0023] The limiting platform, insect collecting tube, connecting tube, and air extraction hose have the same inner diameter.

[0024] To ensure the stability and consistency of the suction force set by the air pump when it reaches the opening of the insect collection tube, the pipe diameter of the gas flow path is set to the same diameter. This ensures consistent suction force and provides a basis for precise adjustment for the subsequent adsorption of other insects.

[0025] Beneficial effects: This utility model is used for the suction and collection of small insects, such as thrips and whiteflies. A suction pump provides the suction, and the suction hose allows for operation at various angles. The intermediate connecting tube connects the suction hose and the insect collection tube. The insect collection tube is disposable and needs to be removed and replaced after each collection. Therefore, the insect collection tube and intermediate connecting tube need to be designed to be detachable. To facilitate the production of the insect collection tube and prevent insect escape, a mesh is fixed at the end to prevent insects from escaping. The insect collection tube is transparent, making it easier to observe the number of collected insects and monitor their condition. After each collection, the tail end opening is sealed.

[0035] A device for collecting small insects in the wild includes an air pump 1 and an air pump hose 2 connected to the air pump 1, an intermediate connecting pipe 3 detachably connected to the air pump hose 2, and a transparent insect collecting tube 4 detachably connected to the intermediate connecting pipe 3; the insect collecting tube 4 has an opening at its tail end and a mesh 5 is fixedly installed at one end near the intermediate connecting pipe 3.

[0036] This invention is used for the suction and collection of small insects, such as thrips and whiteflies. A suction pump 1 provides suction, and a suction hose 2 allows for operation at various angles. A connecting tube 3 connects the suction hose 2 and the insect collection tube 4. The insect collection tube 4 is disposable and needs to be removed and replaced after each collection. Therefore, the insect collection tube 4 and the connecting tube 3 are designed to be detachable. To facilitate the production of the insect collection tube 4 and prevent insects from escaping, a mesh 5 is fixed at the end to prevent insects sucked into the tube from escaping. The insect collection tube 4 is transparent, making it easier to observe the number of collected insects and monitor their condition. After each collection, the tail end is sealed.

[0037] The mesh 5 is fixed to the end of the insect collecting tube 4 by an adhesive.

[0038] By using an adhesive such as resin to fix the mesh 5 to the end of the insect collecting tube 4 through curing and bonding, the production method is simple and convenient. At the same time, it can provide a stable adhesion effect, making the mesh 5 less likely to fall off. It also ensures air circulation in the insect collecting tube 4, reduces the accidental death of insects due to the closed environment, and makes the results of insect drug experiments more accurate.

[0039] The insect collecting tube 4 is provided with a limiting platform 41 with an outer diameter larger than the diameter of the insect collecting tube 4 at one end near the middle connecting tube 3, and the middle part of the limiting platform 41 is connected to the insect collecting tube 4. The inner diameter of the intermediate connecting pipe 3 near the insect collecting pipe 4 matches the outer diameter of the limiting platform 41, and an arc-shaped limiting protrusion 31 is provided on the inner side near the opening of the intermediate connecting pipe 3. At least two opening grooves 32 are also provided on the end of the intermediate connecting pipe 3 near the insect collecting pipe 4. The depth of the opening grooves 32 is greater than the distance between the arc-shaped limiting protrusion 31 and the edge of the intermediate connecting pipe 3.

[0040] To ensure the stability of the insect collecting tube 4 after assembly with the intermediate connecting tube 3, and to facilitate disassembly, an arc-shaped limiting protrusion 31 and an opening groove 32 are provided. When the insect collecting tube 4 is inserted into the intermediate connecting tube 3, the elastic deformation property of the plastic material of the intermediate connecting tube 3 causes the limiting platform 41 to spread open at the end of the intermediate connecting tube 3 as it passes the arc-shaped limiting protrusion 31. After the limiting platform 41 passes the arc-shaped limiting protrusion 31, the parts on both sides of the opening groove 32 rebound inward and converge, so that the arc-shaped limiting protrusion 31 is locked at the bottom edge of the limiting platform 41, thereby achieving the limiting and facilitating the subsequent insect suction operation.

[0041] The limiting platform 41 includes a central protrusion 411 that is integral with the insect collecting tube 4 and a sealing rubber ring 412 that surrounds the upper column of the protrusion 411. The outer diameter of the sealing rubber ring 412 is the same as the outer diameter of the bottom of the protrusion 411. The two together form a cylindrical limiting platform 41. On the inner side of the intermediate connecting pipe 3, after the insect collecting pipe 4 is installed, at least one arc-shaped sealing protrusion 33 is provided at the position corresponding to the sealing rubber ring 412.

[0042] In order to ensure that the suction force generated by the air pump 1 is not affected during operation and to facilitate subsequent adjustment of the suction force, a sealing rubber ring 412 and an arc-shaped sealing convex ring 33 are set at the connection. After the insect collection tube 4 is installed, the arc-shaped sealing convex ring 33 and the sealing rubber ring 412 are press-fitted to achieve a sealing effect and prevent gas from entering from the edge gaps and affecting the set suction force.

[0043] At least two symmetrically arranged insertion holes 42 are provided at the end of the insect collecting tube 4 near the middle connecting tube 3. The mesh 5 is pressed and fixed between the end of the insect collecting tube 4 and the pressure plate 6 by a pressure plate 6 with a piercing post 61 on the bottom surface corresponding to the position of the insertion hole 42.

[0044] In order to facilitate the replacement and installation of the mesh 5, a pressure plate 6 with a piercing post 61 and a corresponding insertion hole 42 are set to press the mesh 5 between the two. If the mesh 5 is damaged during use, it can be easily replaced, and it also has the potential for mass production.

[0045] The puncture post 61 is bullet-shaped, with its end cross-section gradually narrowing to resemble a bullet head. The end near the pressure plate 6 is columnar, and its outer diameter matches the inner diameter of the insertion hole 42.

[0046] To make the insertion of the piercing post 61 more secure and to facilitate the piercing of the mesh 5, the bullet-shaped piercing post 61 is designed so that the front end can easily pierce the mesh 5. At the same time, the columnar structure matches the insertion hole 42 to achieve a tight fit and generate a certain amount of friction to prevent the pressure plate 6 from falling off.

[0047] The edge of the pressure plate 6 away from the insect collecting tube 4 is designed with an arc-shaped chamfer.

[0048] To facilitate smoother installation during assembly, the curved chamfer structure acts as a guide, making installation more convenient.

[0049] The tail of the insect collecting tube 4 is designed as a bullet shape with a gradually decreasing cross-section, and the opening position is set in any side direction from the apex of the tail end, so that the opening position is in the inclined position.

[0050] To make insect suction operations more convenient, the opening is positioned on an angled surface, giving operators a clearer view of the suction opening and making it easier to observe its location during suction.

[0051] The middle connecting pipe 3 is configured as a connector at one end near the insect collecting pipe 4 and as a connecting pipe at the other end near the air extraction hose 2. The inner diameter of the connector is larger than the inner diameter of the connecting pipe. The arc-shaped limiting protrusion 31 and the arc-shaped sealing protrusion 33 are both located on the inner side of the connector.

[0052] To facilitate identification during installation, the intermediate connecting pipe 3 is set up as two parts with different pipe diameters. At the same time, the connector with a larger inner diameter has an internal structure that is easier to manufacture and reduces production costs.

[0053] The limiting platform 41, insect collecting tube 4, connecting pipe and air extraction hose 2 have the same inner diameter.

[0054] To ensure the stability and consistency of the suction force set by the air pump 1 when it reaches the opening of the insect collection tube 4, the diameter of the gas flow path is set to be the same. This ensures consistent suction force and provides a basis for precise adjustment for the subsequent adsorption of other insects.
