Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell culture equipment technology, and in particular to a classification incubator for cell culture. Background Technology
[0002] Cell culture refers to a method of simulating the in vivo environment (sterile, suitable temperature, pH, and certain nutritional conditions, etc.) in vitro to enable cells to survive, grow, reproduce, and maintain their main structures and functions. Cell culture is also called cell cloning technology. The formal term in biology is cell culture technology. Cell culture is an indispensable process for both bioengineering technology as a whole and biological cloning technology. Cell culture itself is the large-scale cloning of cells. Cell culture technology can cultivate a large number of cells from a single cell into simple single cells or very little differentiated multicellular cells. This is an essential link in cloning technology. Moreover, cell culture itself is cell cloning. Cell culture technology is an important and commonly used technique in cell biology research. Through cell culture, a large number of cells can be obtained, and cell signal transduction, cell synthesis and metabolism, cell growth and proliferation can be studied.
[0003] However, existing cell culture incubators have many obvious shortcomings: their internal partitions are mostly fixed or have non-adjustable spacing, making it impossible to flexibly adjust the interlayer distance according to the height of the culture vessels. This results in poor spatial adaptability when culturing different types of cells simultaneously. Either the spacing is too large, wasting space, or the spacing is too small, squeezing the samples. It is difficult to meet diverse culture needs, resulting in low space utilization and easy contact with samples during operation, causing contamination. In high-humidity culture environments, due to the lack of directional flow guidance and centralized collection structures, condensate easily accumulates on the surface of the partitions, forming liquid, or drips down the outer wall of the vessels to the lower culture bottles. This not only directly contaminates the samples and leads to experimental failure, but the accumulated liquid also becomes a breeding ground for bacteria and mold. After long-term use, the risk of excessive microorganisms in the incubator increases dramatically, seriously damaging the sterile environment of cell culture.
[0004] In response to this technical problem, this application proposes a sorting incubator for cell culture. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as fixed partitions, inability to adapt to different containers, low space utilization, lack of condensate collection structure, accumulation of liquid contaminating samples, growth of microorganisms, and destruction of the sterile environment. Therefore, this invention proposes a classification incubator for cell culture.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A cell culture incubator includes a chamber body with a rotatably connected sealing door on the front side. A display module and a control button are located at the top front side of the chamber body. A hot air vent is located on the rear side of the inner wall of the chamber body.

A spring plate is fixedly connected to the bottom of each slider. The spring plate is connected to the inner wall of the tray via a spring assembly, and the bottom end of the spring plate is adapted to the inner wall of the reserved slot.
[0008] Furthermore, a sliding groove is provided at the bottom of the fixed support block, and a liquid collection hopper is detachably connected to the inner wall of the sliding groove. A clamping plate is fixedly connected to the left and right ends of the front side of the liquid collection hopper, and the clamping plate is connected to the support plate through a limiting component.
[0009] Furthermore, the spring assembly includes a fixing block, which is fixedly connected to the rear end of the spring plate. A first spring is fixedly connected to the rear side of the fixing block, and the other end of the first spring is fixedly connected to the inner wall of the support plate.
[0010] Furthermore, the limiting component includes a slide rod, which is slidably connected to the inner walls of the left and right ends of the tray. The front end of the slide rod passes through the front side of the tray and is rotatably connected to a limiting plate. A second spring is sleeved on the middle of the outer side of the slide rod, and the right end of the limiting plate is adapted to the clamping plate.
[0011] Furthermore, the diameter of the rear end portion of the slide rod is larger than that of the middle portion, and the rear end of the second spring abuts against the front side of the rear end of the slide rod.

[0017] 2. In this utility model, the combined structure of the through trough, the liquid collection hopper and the collection box can collect and centrally treat condensate in a directional manner, avoiding the situation in existing equipment where condensate accumulates at the bottom or drips and contaminates the lower sample, reducing the risk of bacterial growth and ensuring a clean culture environment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3An embodiment of this utility model provides a cell culture classification incubator, including a box body 1, a sealing door 2 rotatably connected to the front side of the box body 1, a display module 5 and a control button 6 at the top front side of the box body 1, a hot air vent 7 on the rear side of the inner wall of the box body 1, fixed support blocks 8 fixedly connected to the left and right sides of the inner wall of the box body 1, a reserved slot 11 at the middle of the top side of the fixed support block 8, a tray 12 detachably connected to the outer wall of the fixed support block 8, sliders 17 slidably connected to the left and right ends of the top side of the tray 12, a spring plate 14 fixedly connected to the bottom of the slider 17, the spring plate 14 being connected to the inner wall of the tray 12 through a spring assembly, and the bottom end of the spring plate 14 being adapted to the inner wall of the reserved slot 11;
[0027] Specifically, this incubator aims to address the problems of existing incubators lacking the ability to independently adjust the partition space, being unable to culture different cells simultaneously, having limitations on the height of culture vessels, and being prone to condensation in high humidity environments with a lack of collection structures, leading to condensation accumulation or dripping that contaminates samples and breeds bacteria. This incubator addresses these issues by installing fixed supports 8 on the left and right sides of the inner wall of the chamber 1, with pre-drilled slots 11 on the fixed supports 8. Combined with the spring plate 14 and spring assembly at the bottom of the tray 12, this allows for flexible height adjustment of the tray 12. Specifically, when adjusting the height of the tray 12, simply press the spring plate 14 backward to compress the first spring 16, at which point the spring... Once the bottom end of the spring plate 14 disengages from the reserved slot 11, the tray 12 can be pulled out and reinstalled in the appropriate position. After being released, the first spring 16 returns to its original position, and the bottom end of the spring plate 14 is pushed into the corresponding reserved slot 11 by the fixing block 15, thus achieving a stable installation of the tray 12. The slider 17 assists the spring plate 14 to slide smoothly within the tray 12, ensuring a smooth adjustment process. In this way, users can adjust the distance between each tray 12 according to the height requirements of different cell culture vessels, thereby adapting to various sizes of culture flasks, culture dishes, etc., meeting the needs of culturing different types of cells at the same time, greatly improving the utilization rate of the internal space of the box 1, and facilitating experimental operation and management.
[0028] Reference Figures 3-5The bottom of the fixed support block 8 is provided with a sliding groove 9, and a liquid collecting hopper 22 is detachably connected to the inner wall of the sliding groove 9. A clamping plate 21 is fixedly connected to the left and right ends of the front side of the liquid collecting hopper 22. The clamping plate 21 is connected to the support plate 12 through a limiting component. The spring assembly includes a fixed block 15, which is fixedly connected to the rear end of the spring plate 14. A first spring 16 is fixedly connected to the rear side of the fixed block 15, and the other end of the first spring 16 is fixedly connected to the inner wall of the support plate 12. The limiting component includes a sliding rod 18, which is slidably connected to the inner walls of the left and right ends of the support plate 12. The sliding rod 18 has its front end passing through the front side of the support plate 12 and rotatably connected to the limiting plate 20. A second spring 19 is sleeved on the middle of the outer side of the sliding rod 18. The right end of the limiting plate 20 is adapted to the clamping plate 21. The diameter of the rear end of the sliding rod 18 is larger than that of the middle end. The rear end of the second spring 19 abuts against the front side of the rear end of the sliding rod 18. The clamping plate 21 is L-shaped. A through groove 13 is opened on the top side of the support plate 12. A collection box 10 is detachably connected to the bottom of the inner wall of the box 1. A heat dissipation groove 4 is opened on the bottom front side of the box 1. An observation window 3 is provided on the front side of the sealing door 2.
[0029] Specifically, addressing the issue of condensation easily forming inside incubators under high humidity conditions, and the lack of a collection structure in existing devices leading to condensation accumulation on the inner wall or falling from the upper culture flask into the lower culture flask, causing sample contamination or bacterial growth, this incubator addresses this problem by creating a through groove 13 on the top side of the tray 12 and a sliding groove 9 on the bottom of the fixed support block 8, which is detachably connected to a collection hopper 22. The L-shaped retaining plate 21 on the front side of the collection hopper 22 cooperates with a limiting component on the tray 12. Under the elastic force of the second spring 19, the sliding rod 18 of the limiting component drives the limiting plate 20 to tightly abut against the retaining plate 21, achieving a stable installation of the collection hopper 22. When condensation forms on the tray 12, it flows into the collection hopper 22 through the through groove 13, and then through the collection hopper 22... 2. The condensate is collected in the collection box 10 at the bottom of the inner wall of the chamber 1, which effectively avoids the accumulation of condensate on the surface of the tray 12 or direct dripping into the lower culture bottle, thus preventing sample contamination. At the same time, the detachable collection funnel 22 and collection box 10 facilitate regular cleaning, prevent bacterial growth, and ensure the cleanliness and stability of the cell culture environment. In addition, the sealing door 2, which is rotatably connected to the front of the chamber 1, ensures the airtightness of the internal environment. The observation window 3 on the sealing door 2 allows the experimenter to observe the internal culture at any time. The display module 5 and control button 6 on the top front of the chamber 1 allow users to set and view parameters such as the internal temperature. The hot air vent 7 is used for hot air circulation inside the chamber to maintain a constant temperature, and the heat dissipation groove 4 at the bottom front of the chamber 1 helps to dissipate heat from the equipment and ensure the stable operation of the device.
[0030] Working Principle: During use, parameters are set via control button 6, display module 5 shows the real-time status inside the chamber, hot air outlet 7 outputs hot air to maintain a constant temperature, heat dissipation slot 4 assists in heat dissipation, sealing door 2 is closed to ensure a sealed internal environment, and observation window 3 facilitates observation of the internal conditions. When adjusting the height of tray 12, press spring plate 14 to compress the first spring 16, causing it to disengage from the reserved slot 11. After moving to the appropriate position, release the spring plate 14, which then pushes the spring plate 14 into the slot for fixation. Slider 17 ensures smooth adjustment. When installing the liquid collection hopper 22, push it along the slide groove 9. The second spring 19 pushes the slide rod 18 to make the limiting plate 20 press against the L-shaped locking plate 21 to complete the fixation. Condensate on tray 12 flows into liquid collection hopper 22 through through groove 13 and then into bottom collection box 10 to avoid contamination. When disassembling liquid collection hopper 22 and collection box 10, simply reverse the operation of the limiting components for easy cleaning. All structures work together to achieve flexible space adjustment, effective collection of condensate, and stable maintenance of a constant temperature environment.
