Description

Technical Field

[0001] This utility model relates to an insect-absorbing device for small insects, belonging to the technical field of insect research equipment. Background Technology

[0002] Insect life tables are powerful tools for tracking insect population dynamics and forecasting. They are statistical tables describing the survival and mortality processes of populations. As one of the important scientific techniques for studying insect population mortality, survival rate, and reproductive rate, they play a vital role in insect biology and ecology. Many insect ecological experiments require starvation treatment of insects. However, conducting sexual life table experiments or starvation treatments on parasitic wasps and small bugs requires capturing a large number of insects. Due to their small size, these small insects require careful handling during capture to avoid death. Furthermore, the captured small insects need to be transferred back to the experimental setup, resulting in a significant workload and severely limiting the experimental time. Moreover, during food replacement, small insects may escape, leading to inaccurate data or requiring the experiment to be repeated. Summary of the Invention

[0003] The purpose of this invention is to provide a suction device for small insects. This device can quickly suction and capture insects, and the captured small insects can be directly raised in replaceable rearing tubes, reducing the workload of the experimental process, improving experimental efficiency, and eliminating concerns about small insects escaping.

[0004] The technical solution of this utility model is as follows: A suction device for small insects includes a feeding tube, with a detachable upper tube and a lower tube connected to the upper and lower ends of the feeding tube, respectively. The top opening of the upper tube is an air inlet, and the bottom opening of the lower tube is an insect suction inlet. A mesh is provided near the upper end of the feeding tube, and a lateral pipe is provided in the middle of the feeding tube. The lateral pipe is filled with cotton, and the outer end of the lateral pipe is a water inlet with a cover.

[0005] In the aforementioned insect-absorbing device for small insects, the feeding tube and the upper and lower tubes are connected by a movable plug-in connection.

[0006] In the aforementioned insect-absorbing device for small insects, the insect-absorbing opening is a constricted structure; the air-absorbing opening is a flared structure.

[0007] In the aforementioned insect-absorbing device for small insects, the feeding tube, upper tube, and lower tube are all transparent pipes.

[0008] In the aforementioned insect-absorbing device for small insects, multiple blocking strips are provided on the inner wall of the lateral tube at the front end of the cotton.

[0009] In the aforementioned insect-absorbing device for small insects, a mesh screen is provided near the air intake on the upper tube.

[0010] In the aforementioned insect suction device for small insects, the top surface of the partition net is ≥1.5cm away from the upper port of the feeding tube; a retaining ring is provided inside the feeding tube near the lower port, and the bottom surface of the retaining ring is ≥1.5cm away from the lower port of the feeding tube.

[0011] In the aforementioned insect-absorbing device for small insects, an air bladder is provided at the air inlet, a first one-way valve is connected to the upper tube, a lateral connecting tube is connected to the upper tube above the first one-way valve, and a second one-way valve is connected to the other end of the lateral connecting tube.

[0012] The beneficial effects of this invention are as follows: Compared with the prior art, the device of this invention mainly consists of a feeding tube, an upper tube, a lower tube, and a lateral pipe. Insects can be sucked into the feeding tube through suction, greatly reducing the mortality of small insects during the capture process. The feeding tube can be removed separately, and a lid can be placed over the bottom opening to form a small insect feeding device, facilitating related experiments. This eliminates the process of transferring small insects from the capture device to the experimental device, making the entire experimental process simpler and more feasible, and reducing workload. By supplementing the cotton with water or other liquid nutrients such as honey water, the survival needs of the small insects are met. Furthermore, the cotton, lid, and mesh effectively prevent small insects from crawling out of the feeding tube, ensuring the accuracy of experimental data and eliminating the need to repeat the experiment.

[0013] In summary, this invention simplifies life table experiments and insect starvation treatments, reduces operational errors, makes experiments simpler and more feasible, reduces workload, and allows the entire experimental apparatus to be disassembled and replaced, further reducing the workload and improving experimental efficiency.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] An embodiment of this utility model: A suction device for small insects includes a feeding tube 1, with a detachable upper tube 2 and a lower tube 3 connected to the upper and lower ends of the feeding tube 1, respectively. The top opening of the upper tube 2 is an air inlet 4, and the bottom opening of the lower tube 3 is an insect suction inlet 5. A mesh 6 is provided near the upper end of the feeding tube 1, and a lateral pipe 7 is provided in the middle of the feeding tube 1. The lateral pipe 7 is filled with cotton 8, and the outer end of the lateral pipe 7 is a water inlet 9. A cover 10 is provided at the water inlet 9.

[0021] When using this invention to capture small insects, align the suction port 5 with the small insect, and then suck air through the air intake port 4. Since the water inlet 9 of the side pipe 7 is equipped with a cover 10, external air can only enter the device through the suction port 5. Through suction, the small insect can be sucked from the suction port into the feeding tube 1. After being blocked by the partition net 6, the small insect can no longer rise with the air. The entire capture process does not require tools to directly clamp the small insect, thus avoiding the death of the small insect due to improper operation during the capture process. Moreover, the entire capture process does not require careful handling and the insect capture can be completed quickly.

[0022] After the insects are captured, remove the upper tube 2 and the lower tube 3, and then place a cap 10 on the bottom end of the rearing tube 1 to obtain the following result: Figure 2 The structure shown forms a separate small insect rearing device, facilitating life table experiments and insect starvation treatment. It eliminates the need to transfer small insects from the capture device to the experimental setup, simplifying the entire experiment and reducing workload. During the experiment, opening the cover 10 at the water inlet 9 allows water or other liquid nutrients, such as honey water, to be added to the cotton 8, meeting the survival needs of the small insects. The cotton 8, the two covers 10, and the mesh 6 effectively prevent small insects from crawling out of the rearing tube 1, ensuring the accuracy of the experimental data and eliminating the need to repeat the experiment. The mesh 6 prevents insects from crawling out while allowing air to enter the rearing tube 1. Then, replacing the rearing tube 1 allows for the capture of other small insects.

[0023] The feeding tube 1 is connected to the upper tube 2 and the lower tube 3 by a movable plug-in connection, which can realize quick connection and disassembly between the feeding tube 1 and the upper tube 2 and the lower tube 3.

[0024] The insect suction port 5 has a constricted structure, which creates a strong airflow at the insect suction port 5, making it easy to suck small insects into the feeding tube 1; the air intake port 4 has a flared structure, which makes it convenient for people to inhale directly with their mouths.

[0025] The feeding tube 1, upper tube 2, and lower tube 3 are all transparent tubes, which facilitates observation of the internal conditions of the tubes, such as whether insects have been captured or whether there are impurities inside the tubes.

[0026] Multiple blocking strips 11 are provided on the inner wall of the lateral pipe 7 at the front end of the cotton 8. The blocking strips 11 are mainly used to block the cotton 8 and prevent the cotton 8 from moving into the lateral pipe 7 under the action of suction, which may eventually fall into the feeding pipe 1 and cause the feeding pipe 1 to be blocked.

[0027] A mesh 12 is provided on the upper tube 2 near the air inlet 4. The mesh 12 is mainly used to prevent impurities from falling into the upper tube 2 through the air inlet 4 and contaminating the pipe. At the same time, it can block some small objects during the air intake process and prevent them from entering the person's mouth through the air inlet 4.

[0028] The top surface of the partition net 6 is at least 1.5 cm away from the upper end of the feeding tube 1. A retaining ring 13 is fixedly installed inside the feeding tube 1 near the lower end, with the bottom surface of the retaining ring 13 at least 1.5 cm away from the lower end of the feeding tube 1. The partition net 6 and the retaining ring 13 also function as a limiting device. When the upper tube 2 and lower tube 3 are inserted into the feeding tube 1, the bottom of the upper tube 2 abuts against the top surface of the partition net 6, indicating that the feeding tube 1 and the upper tube 2 are properly connected. Similarly, when the top surface of the lower tube 3 abuts against the ground of the retaining ring 13, it indicates that the feeding tube 1 and the lower tube 2 are properly connected. This design ensures a secure connection between the feeding tube 1 and the upper and lower tubes 2 and 3, preventing loosening or falling off during use.

[0029] An airbag 14 is provided at the air intake 4. A first one-way valve 15 is connected to the upper tube 2. A lateral connecting tube 16 is connected to the upper tube 2 above the first one-way valve 15. A second one-way valve 17 is connected to the other end of the lateral connecting tube 16. This configuration is as follows. Figure 4As shown, by setting up the air bladder 14, air can be inhaled without using the mouth. Before sucking the insect, press the air bladder 14. The air in the air bladder 14 is discharged through the second one-way valve 17 on the side connecting pipe 16. During the air bladder 14 discharge, the first one-way valve 15 is closed. Then, aim the suction port 5 at the small insect and release the air bladder 14. The air bladder 14 will suck air. At this time, the first one-way valve 15 opens, and air enters the air bladder 14 through the lower pipe 3, the feeding pipe 1, and the upper pipe 2. At the same time, the second one-way valve 17 closes, and air cannot enter the upper pipe 2 through the second one-way valve 17. This design can better achieve the capture of insects.
