This device is particularly suitable for convenient and efficient collection of trace nectar samples in scenarios such as plant ecology research and insect pollination behavior research. Background Technology

[0002] In fields such as plant ecology and insect pollination behavior research, nectar collection is a crucial foundational task. Currently used traditional nectar collection methods, such as manual aspiration using glass capillaries or micro-syringes, suffer from inconvenience, low collection efficiency, and susceptibility to sample contamination. Furthermore, existing electric collection devices are often limited in function, lacking adaptability to different nectar viscosities (e.g., suction force adjustment), and provide little intuitive access to device status information (e.g., battery level, current configuration). Container cleaning and replacement are also cumbersome. Therefore, there is an urgent need to develop a miniature nectar collection device with a rational structural design, convenient operation, effective sample contamination prevention, portability, flexible adjustment of collection parameters, and status display functionality.

Detailed Implementation

[0027] The present invention will be further described and illustrated below with reference to specific embodiments. The embodiments described are merely examples of the present disclosure and do not limit the scope of the invention. The technical features of each embodiment of the present invention can be combined accordingly, provided that there is no conflict between them.

[0028] According to a specific embodiment of the present invention, a miniature nectar collection device with multi-specification capillary tubes includes: a multi-specification collection module, a power control module, and a detachable nectar collection module connected vertically in sequence.

[0029] The power control module includes a power pump and a control component. The power pump is used to transport the nectar collected by the collection module to the collection module, and the control component is used to regulate the working state of the device.

[0030] The detachable nectar collection module is used to collect the nectar delivered by the power pump;

[0031] The multi-specification acquisition module includes: a hollow rotating drum 11, several sliders 13, and several multi-specification capillary tubes 1. One end of the rotating drum 11 is movably connected to the power control module. A capillary tube mounting frame is fixed on the inner wall of the rotating drum 11. Several multi-specification capillary tubes are vertically installed on the capillary tube mounting frame 28. One end of several sliders 13 is connected to a capillary tube 1 in a one-to-one correspondence. The side wall of the rotating drum 11 has a groove 12 for the sliders 1 to slide in the vertical direction. The other end of the sliders 13 is installed through the groove 12. By rotating the rotating drum 11, the desired specification of capillary tube 1 is selected to be aligned with the input pipe 2 of the power pump. By sliding the sliders 13, the selected specification of capillary tube 1 is connected to or disconnected from the input pipe 2 of the power pump.

[0032] Example 1:

[0033] like Figure 1 , 2 As shown in Figures 3 and 4, a miniature nectar collection device with multi-specification capillaries is designed with a pen-shaped structure, an axial length of approximately 15 cm, and a maximum radial diameter of approximately 3 cm. The device comprises the following three main functional modules from front to back.

[0034] like Figure 1 and 2As shown, the multi-specification acquisition module has a rotary capillary mounting bracket 11 at the front end of the device. The rotation of the rotary tube 11 is achieved through a slot 21 and a retaining ring 22. The inner wall of the rotary tube is provided with a capillary mounting bracket 28, which is specifically an annular plate. Five mounting positions 25 are evenly opened around the annular plate 11. Each mounting position 25 fixes a glass capillary tube 1. The inner diameter of each capillary tube is different (e.g., 0.1, 0.2, 0.3, 0.4, 0.5 mm). The end of each capillary tube is provided with a second adapter 20 that matches the input pipe 2. By rotating the rotating drum 11, the calibration line 27 of the target specification capillary is aligned with the second calibration line 26 of the outer casing 10. Then, the capillary can be raised or lowered by moving the slider 13 in the slide groove 12 on the side of the rotating drum 11 up and down. The slider 13 is fixed with a first baffle 14 and a second baffle 15 that are respectively in close contact with the inner and outer walls of the rotating drum 11, ensuring that the slider can be positioned at any position within the slide groove 12. When the slider 13 slides to the target position, the friction between the first baffle 14 and the second baffle 15 and the rotating drum wall can resist gravity, allowing the slider to be stably suspended at any height within the slide groove 12. The second adapter 20 at the end of the target capillary is then inserted into the input pipe 2.

[0035] Power Control Module: A miniature diaphragm pump 3 is installed in the middle of the device, with a flow rate range of 0.3-0.8 L / min, powered by a built-in rechargeable battery 6. The inlet of the miniature diaphragm pump 3 is connected to the multi-specification collection module via an input pipe 2. When the miniature diaphragm pump 3 starts, it generates a controllable negative pressure (suction) at the rear end of the capillary. This suction, in conjunction with capillary action, significantly accelerates the entry of nectar through the capillary into the device, improving collection speed and efficiency. The miniature diaphragm pump 3 is equipped with a control switch 5. The control switch 5 is located on the side of the main casing 10 of the device, allowing for easy one-handed operation to turn the miniature diaphragm pump 3 on or off. A speed controller 8 is also provided, connected to the miniature diaphragm pump 3 via a circuit. The user can adjust the working power of the miniature diaphragm pump 3 in real time via the speed controller 8, thereby precisely controlling the suction force to adapt to nectar with different viscosities or collection speed requirements. A display screen 9 is located on the side of the casing 10 in an easily observable position (near the control switch area), connected to the rechargeable battery 6 via a circuit. The display screen 9 is used to display key status information, including the current battery level, the selected capillary inner diameter specification, and the current working status of the diaphragm pump.

[0036] Detachable Nectar Collection Module: This module, located at the rear of the device, is an independent, well-sealed container, comprising a container body 7 and a sealing cap 16. The front end of the container body 7 has an external thread 23 for connection to the outer shell and a first adapter 18. The external thread 23 matches the internal thread groove 24 at the end of the power control module's outer shell, and the first adapter 18 matches the output pipe 4, enabling communication with the micro diaphragm pump 3. Its main function is to receive and store nectar samples delivered by the micro diaphragm pump 3. The container body 7 is made of transparent plastic, allowing users to visually observe the amount of nectar stored inside. The rear end of the container body 7 has an opening structure, and the sealing cap 16 is connected via an external thread 17. After collecting nectar of one type, or when the container needs cleaning, the entire detachable nectar collection module can be easily removed from the main body of the device. The container can be immediately replaced with another clean spare container for the next type of nectar collection. The disassembled container body 7 and sealing cap 16 can be thoroughly cleaned and dried in the laboratory to effectively prevent sample contamination and spoilage caused by residual nectar.

[0037] Example 2:

[0038] When using the miniature nectar collection device described in Example 1 to collect nectar, the specific operating steps are as follows:

[0039] Capillary Selection: Select a capillary with an appropriate inner diameter based on the nectar characteristics of the target flower and the required collection speed. First, move all sliders 13 downwards to the lower end of the groove 12, so that all capillary sizes extend from the front end of the device. Then, rotate the rotating cylinder 11 at the front end of the device to align the calibration line 27 of the target size capillary with the second calibration line 26 of the outer casing 10. Move the slider 13 of the target size capillary upwards to the middle of the groove 12. Figure 5 This allows the adapter 20 at the end of the target size capillary to be inserted into the input pipe 2, ensuring that the target size capillary extends from the bottom of the rotating drum. Then, the sliders of other capillary tubes are pushed upward to the upper part of the slide groove 12. The friction between the first baffle 14 and the second baffle 15 on the slider 13 and the wall of the rotating drum will keep the slider suspended, causing the remaining capillary tubes to retract into the device to avoid affecting nectar collection.

[0040] Container installation: Inspect and ensure that the first adapter 18 on the bottom surface of the container body 7 is clean and dry. Figure 1 and 2 Align the first adapter 18 at the front end of the container body 7 with the output pipe 4 on the fixing frame 19, rotate the container body 7 until it is tightened and fixed, forming a sealed connection between the output pipe 4 and the first adapter 18.

[0041] Parameter viewing and setting: Check the display screen 9 on the side of the device to confirm that the rechargeable battery 6 has sufficient power and that the displayed capillary specifications match the selected parameters. If needed, set the appropriate suction level for the micro diaphragm pump 3 using the speed controller 8 (e.g., increase the suction for viscous nectar).

[0042] Start the collection: Turn on the control switch 5 on the side of the device to start the micro diaphragm pump 3. Align the selected capillary tube 1 at the front of the device with the flower from which nectar needs to be collected (e.g., insert the corolla). Under the combined action of capillary action and the suction of the micro diaphragm pump 3, the nectar passes through the capillary tube 1 and the input pipe 2, and is then drawn into the diaphragm pump 3. Finally, the micro diaphragm pump 3 delivers the nectar through the output pipe 4 to the container 7, which is connected to it via the first adapter 18.

[0043] Observation and Stop: Observe through the transparent container 7. After collecting the required amount of nectar, turn off the control switch 5 to stop the micro diaphragm pump 3 from working.

[0044] Sample transfer: Unscrew the sealing cap 16 at the end of the removable nectar collection module and carefully pour the nectar from the container 7 into the marked collection tube (such as a centrifuge tube) for storage.

[0045] Container handling: Loosen and remove the container containing residual nectar. If you need to collect another type of nectar immediately, take a clean, dry spare container and attach it to the apparatus. The removed container can be thoroughly cleaned in the laboratory with a suitable solvent (such as deionized water or dilute alcohol) and dried for later use.

[0046] Cleaning steps after collection: a) Insert the used capillary tube into a container filled with cleaning solution (such as deionized water or dilute alcohol); b) Turn on control switch 5 and start diaphragm pump 3 to pump until the cleaning solution is free of impurities; c) Disassemble the used collection container 7 and clean it with cleaning solution.
