Abstract
Description
Technical Field
[0001] This utility model relates to the field of collection device technology, and in particular to a fruit fly culture and collection device. Background Technology
[0002] As is well known, fruit flies, belonging to the family Drosophila in the order Diptera, are small insects that typically feed on rotting fruit, hence their name. They are of great value in scientific research, especially in the field of genetics, because fruit flies have a simple genetic structure, a short lifespan, and are easy to culture. They are widely used in research on gene function, genetic laws, and biological development. Fruit fly culture usually requires the use of collection devices, as these devices can effectively separate the fruit flies from the culture environment, facilitating subsequent experimental operations and analysis.
[0003] However, traditional fruit fly culture and collection devices are usually disposable, making it difficult to replace the culture medium. As the fruit flies grow and reproduce, the nutrients in the culture medium are gradually depleted, and metabolic products such as fruit fly excrement accumulate, causing the culture medium to deteriorate. This affects the growth, development, reproduction rate, and lifespan of the fruit flies, and consequently affects the accuracy and reliability of experimental results. Therefore, it is urgent to carry out technical improvements. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fruit fly culture and collection device. In use, the sliding push block compresses the limiting spring, simultaneously moving the locking block into the storage slot. The positioning block and positioning slot then facilitate the positioning of the culture rack. When the locking block aligns with the limiting slot, the push block is released, releasing the limiting spring's force and causing the locking block to engage with the limiting slot, thus limiting the culture rack. This allows for the disassembly of the culture rack, preventing deterioration of the culture environment due to nutrient depletion, spoilage, and accumulation of fruit fly excrement.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A fruit fly culture and collection device includes an outer shell, a bottom cover on the lower surface of the outer shell, a rotating rod and a rotating auxiliary rod rotatably connected to the outer wall of the outer shell, a sliding groove on the lower surface of the rotating rod and the rotating auxiliary rod, a return spring fixedly connected to the top surface of the sliding groove, a sliding rod fixedly connected to the lower end of the return spring, a stop rod fixedly connected to the outer wall of each pair of sliding rods on adjacent sides, a fly inlet tube fixedly connected to the middle of the lower surface of the outer shell, a plurality of flow grooves on the outer wall of the fly inlet tube, a plurality of positioning grooves on the lower surface of the outer shell, a positioning block slidably connected to the inner wall of the positioning groove, a culture rack fixedly connected to the side adjacent to the positioning block, a fly outlet tube fixedly connected to the lower end of the fly inlet tube, and a control valve sleeved on the lower end of the fly outlet tube through the culture rack to the inner wall of the bottom cover.
[0007] Multiple storage slots are provided on the lower surface of the outer shell near the positioning slot. Push blocks are slidably connected to the inner wall of each storage slot. Multiple limiting springs are fixedly connected to the outer wall of the opposite side of each push block. The outer wall of the opposite side of each limiting spring is fixedly connected to the storage slot. A snap-fit block is fixedly connected to the outer wall of the side adjacent to each push block.
[0008] Compared with existing fruit fly culture and collection devices, this fruit fly culture and collection device, through the above technical solution, facilitates the positioning of the bottom cover by the abutment block and the abutment groove. By first rotating the auxiliary rod, the upper abutment rod is driven to abut laterally against the cross groove. Then, by rotating the rotating rod, the lower abutment rod is driven to abut longitudinally against the cross groove, and the two end slots are engaged. This not only limits the bottom cover but also provides secondary limiting for the lower culture rack, making the fit between the bottom cover and the main body of the device tighter. This helps to improve the sealing of the device, prevent fruit flies from escaping and external pollutants from entering, and provide a stable and closed environment for fruit fly culture. It has high practical performance.
[0009] Furthermore, an inlet frame is connected through the middle of the upper surface of the outer shell, and a plug is threaded to the upper end of the inner wall of the inlet frame;
[0010] The above technical solution facilitates sealing of the feed rack by using a plug.
[0011] Furthermore, the upper surface of the outer casing is provided with multiple ventilation holes, and the inner wall of each ventilation hole is provided with a dust filter.
[0012] The above technical solution ensures gas flow through ventilation holes and prevents external dust from entering through dust filters.
[0013] Furthermore, an acrylic sheet is embedded in the outer wall of the outer shell;
[0014] The above technical solution allows for easy viewing of the fruit flies inside the acrylic sheet.
[0015] Furthermore, the lower end of the outer wall of the culture rack is provided with multiple limiting grooves, and the snap-fit blocks are snap-fitted into the limiting grooves respectively;
[0016] With the above technical solution, the snap-fit blocks are snapped into the limiting grooves, which facilitates the initial positioning of the culture rack.
[0017] Furthermore, a groove is provided at the edge of the lower surface of the culture rack, and a block is fixedly connected to the edge of the upper surface of the bottom cover, the block abutting against the groove;
[0018] The above technical solution facilitates the positioning of the bottom cover by using the abutment block and the abutment groove to abut against each other.
[0019] Furthermore, a slot is provided in the middle of the outer wall of each adjacent end of the abutment rod, and the slots abut against each other. A cross groove is provided on the lower surface of the bottom cover, and the abutment rod abuts against the cross groove respectively.
[0020] The above technical solution allows for the limiting of the bottom cover by having the abutments abut against the cross grooves.
[0021] Furthermore, a second limiting groove is provided on the outer wall of each adjacent side of the storage slot, and a limiting block is fixedly connected to both sides of the outer wall of the push block. The limiting blocks are slidably connected to the inner wall of the second limiting groove.
[0022] The above technical solution allows for the slidable connection of the limiting blocks to the inner wall of the limiting groove two, facilitating the limiting of the push block.
[0023] This utility model has the following beneficial effects:
[0024] 1. The present invention proposes a fruit fly culture and collection device. Compared with existing fruit fly culture and collection devices, when this device is in use, the sliding push block drives the limiting spring to compress and move the locking block into the storage slot. Subsequently, the positioning block and the positioning slot facilitate the positioning of the culture rack. When the locking block and the limiting slot are aligned, the push block is released, the limiting spring releases its force, and the locking block and the limiting slot are locked together, thereby limiting the culture rack. The culture rack can be disassembled to prevent the culture environment from deteriorating due to the depletion of nutrients in the culture medium, spoilage, and accumulation of fruit fly excrement.
[0025] 2. The fruit fly culture and collection device proposed in this utility model, compared with the existing fruit fly culture and collection devices, facilitates the positioning of the bottom cover by the abutment block and the abutment groove during use. By first rotating the secondary rod, the upper abutment rod is driven to abut against the cross groove laterally. Then, the rotating rod is rotated to make the lower abutment rod abut against the cross groove longitudinally, and the two end slots are fitted together. This can limit the bottom cover and provide secondary limit for the lower culture rack, making the fit between the bottom cover and the main body of the device tighter. This helps to improve the sealing of the device, prevent fruit flies from escaping and external pollutants from entering, and provide a stable and closed environment for fruit fly culture. It has high practical performance. Attached Figure Description

This allows for the installation and removal of the culture rack 18. The abutment block 114 abuts against the abutment groove 111, facilitating the positioning of the bottom cover 112. First, by rotating the auxiliary rod 21 in conjunction with the return spring 24, the abutment rod 25 is stretched, so that the upper abutment rod 25 abuts laterally against the cross groove 113. Then, by rotating the rotating rod 2 in conjunction with the return spring 24, the abutment rod 25 is stretched, so that the lower abutment rod 25 abuts longitudinally against the cross groove 113, and the two end slots 26 are engaged. This can limit the bottom cover 112 and limit the lower culture rack 18. By opening the plug 12, fruit flies are put in and flow into the outer shell 1 through the fly inlet tube 15.
