Description

Technical Field

[0001] This application relates to the technical field of incubators, and in particular to a temperature and humidity control device for a carbon dioxide incubator. Background Technology

[0002] A carbon dioxide incubator is a sophisticated device used for the culture of cells, tissues, or microorganisms. It primarily provides a stable growth environment for in vitro experiments by simulating the environmental conditions inside a living organism (such as constant temperature, humidity, and gas concentration).

[0003] Existing CO2 incubators mainly consist of an incubator body, a temperature and humidity control system, and a humidity generator. The incubator body is equipped with a resistance wire heating element, a temperature sensor, and a humidity sensor, while an external humidity generator is connected. The system employs a closed-loop control principle: the temperature sensor monitors the incubator temperature in real time; when the detected temperature is lower than the set value, the resistance wire heating is automatically activated until the set value is reached, at which point heating stops. Simultaneously, the humidity sensor continuously monitors the humidity inside the incubator; when the humidity falls below a set threshold, the system activates the external humidity generator. The generated saturated water vapor is delivered into the incubator through a dedicated air duct, achieving precise humidity control. Once the humidity reaches the preset parameters, the humidity generator automatically shuts off.

[0004] Regarding the aforementioned technologies, in experimental scenarios where multiple sets of specimens need to be cultured under different environmental conditions, the highly uniform environmental parameters inside the chamber make it difficult to construct multiple differentiated culture microenvironments within the chamber. This results in the inability to simultaneously carry out the culture of multiple sets of specimens, thus requiring the sequential culture of multiple sets of specimens, which is time-consuming and labor-intensive, leading to low specimen culture efficiency. Utility Model Content

[0005] To improve the efficiency of specimen culture, this application provides a temperature and humidity control device for a carbon dioxide incubator.

[0006] The temperature and humidity control device for a carbon dioxide incubator provided in this application adopts the following technical solution:

[0007] A temperature and humidity control device for a carbon dioxide incubator includes a chamber body. Partitions are fixedly installed on the inner walls of opposite sides of the chamber body. A humidity generator is installed on one side of the chamber body. An air outlet pipe is fixedly installed at the outlet end of the humidity generator. The end of the air outlet pipe away from the humidity generator passes through one side wall of the chamber body and is fixedly connected to the chamber body. A diverter pipe is fixedly installed at the end of the air outlet pipe inside the chamber body. Both ends of the diverter pipe are closed. Multiple delivery pipes are fixedly installed on the diverter pipe, arranged sequentially in a vertical direction. The ends of the delivery pipes away from the diverter pipe pass through adjacent partitions. The delivery pipes and partitions are fixedly connected. An electrically controlled valve is installed on the delivery pipe. One end of the chamber body is designed to be open. The enclosure has a closed door at the open end. A sliding rod is fixed to the side of the closed door facing the inside of the enclosure. The sliding rod is horizontal and slidably connected to the inner wall of the enclosure. Multiple support plates are fixed to the side of the closed door facing the inside of the enclosure. The multiple support plates are arranged in sequence along the vertical direction. The conveying pipe corresponds to each support plate. Multiple sets of heating elements are fixed to the side wall of the enclosure away from the closed door. The multiple sets of heating elements are arranged in sequence along the vertical direction. The heating elements correspond to each support plate. Temperature sensors and humidity sensors are fixed to the partition. Multiple temperature sensors and humidity sensors are provided. Each temperature sensor and humidity sensor corresponds to a support plate.

[0008] By adopting the above technical solution, when culturing multiple sets of specimens, the sealing door is first pulled away from the chamber, causing the sliding rod and support plate to move outward synchronously. After the support plate is completely removed from the chamber, different specimens are placed on their respective support plates. Then, the sealing door is pushed inward to reset the support plate under the guidance of the sliding rod. When the sealing door is fully closed, the end of the support plate away from the sealing door is tightly fitted against the inner wall of the chamber, while the two sides of the support plate abut against the partitions, thus forming multiple independent insulated chambers. Both the support plate and the partitions are made of insulation material. Next, the humidity generator and heating element are activated. The gas generated by the humidity generator enters the distribution pipe through the gas guide pipe and is then distributed to different chambers through the delivery pipes. During this process, temperature and humidity sensors monitor environmental parameters in real time. When a chamber reaches the set temperature, the corresponding heating element automatically stops working; when the set humidity is reached, the corresponding electronically controlled valve closes to block gas input. After all chambers have met the culture requirements, the humidity generator is turned off. This achieves simultaneous culture of multiple sets of specimens under different temperature and humidity conditions, thereby improving the efficiency of specimen culture.

[0009] Optionally, a first guide rail is fixed to the side wall of the box body. The length direction of the first guide rail is parallel to the length direction of the slide rod, and the end of the slide rod away from the closed door extends into the first guide rail and is slidably connected to the first guide rail.

[0010] By adopting the above technical solution, during the movement of the closed door, the closed door drives the sliding rod to move within the first guide rail, and the setting of the first guide rail realizes the sliding connection between the sliding rod and the box body.

[0011] Optionally, multiple second guide rails are fixed on opposite sides of the two partitions. The multiple second guide rails are arranged sequentially in the vertical direction. The length direction of the second guide rails is parallel to that of the support plate. The two ends of the multiple support plates are respectively embedded in the corresponding second guide rails of the two partitions. The support plates and the second guide rails are slidably connected.

[0012] By adopting the above technical solution, when the closed door moves, the support plate moves along the second guide rail. When a specimen is placed on the support plate, the second guide rail supports the support plate, making it less likely for the support plate to tilt.

[0013] Optionally, the side wall of the enclosure is fixed with a shell, the side of the shell facing the closed door is set as an opening, a snap-fit ​​rod is provided on the shell, the snap-fit ​​rod passes through one side wall of the shell and is slidably connected to the shell, a pull plate is fixed at one end of the snap-fit ​​rod outside the shell, a spring is fixed between the pull plate and the side wall of the shell, the spring is sleeved outside the snap-fit ​​rod, a fixing rod is fixed on the side wall of the closed door, the side wall of the fixing rod has a snap-fit ​​groove, and the snap-fit ​​rod and the snap-fit ​​groove are snap-fitted and adapted.

[0014] By adopting the above technical solution, during the process of pushing the closed door towards the box, the closed door drives the fixed rod to move. The fixed rod gradually moves into the shell, while the locking rod moves away from the shell. The spring is stretched. After the closed door and the box come into contact, the locking rod and the locking groove are aligned. The spring contracts, driving the pull plate to move. The pull plate drives the locking rod to move towards the locking groove. One end of the locking rod is locked into the locking groove, realizing the locking and fixing of the fixed rod and the shell. This achieves the fixation of the closed door and the box, making it difficult for the closed door to move relative to the box after it is closed.

[0015] Optionally, the side of the latching rod away from the pull plate is set as an inclined surface.

[0016] By adopting the above technical solution, during the process of the fixing rod moving towards the inside of the housing, the end of the fixing rod first contacts the inclined surface of the locking rod and pushes the locking rod to move away from the housing. Thus, during the process of fixing the closed door, there is no need for the staff to manually pull the pull plate away from the housing, which provides convenience for the staff.

[0017] Optionally, a limiting plate is provided inside the housing, and the locking rod passes through the limiting plate, with the locking rod and the limiting plate being fixedly connected.

[0018] By adopting the above technical solution, when disconnecting the closed door and the box, the pull plate is pulled away from the shell. The pull plate moves the locking rod, and the locking rod moves the limiting plate. After the locking rod and the locking groove are separated, the limiting plate abuts against the inner wall of the shell, making it difficult for the locking rod to continue to move away from the shell, thus making it difficult for the locking rod to separate from the shell.

[0019] Optionally, a brake rod is rotatably connected to one end of the latching rod outside the housing, and the housing is fixed with a lap plate for lapping the brake rod.

[0020] By adopting the above technical solution, during the process of pulling the plate away from the shell, the plate drives the locking rod to move, and the locking rod drives the brake rod to move. When the locking rod and the locking groove are disengaged, the brake rod is rotated, and one end of the brake rod overlaps the overlapping plate, making it difficult for the plate to move towards the shell under the action of the spring.

[0021] Optionally, a baffle is fixed to the side of the upper surface of the support plate.

[0022] By adopting the above technical solution, when placing the specimen on the support plate, the specimen is in the area enclosed by the baffle and the closed door. During the movement of the support plate, the baffle blocks the specimen, making it difficult for the specimen to detach from the support plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Multiple independent insulated chambers are constructed by support plates and partitions made of thermal insulation material. Under the coordinated control of temperature sensors, humidity sensors and electronic valves, each chamber can maintain different temperature and humidity conditions, thereby enabling the simultaneous culture of multiple sets of specimens under different environments and improving the efficiency of specimen culture.

[0025] 2. By using the snap-fit ​​rod and the fixing rod, the closed door and the box are fixed together, making it difficult for the closed door to move relative to the box during the specimen culture process;

[0026] 3. The baffle prevents the specimen from easily falling off the support plate. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a temperature and humidity control device for a carbon dioxide incubator.

[0034] refer to Figure 1 A temperature and humidity control device for a carbon dioxide incubator includes a chamber body 1. One side of the chamber body 1 is open. The chamber body 1 is provided with a sealing door 4 at the open end for sealing the opening. A humidity generator 3 is provided on one side of the chamber body 1. The air outlet of the humidity generator 3 is connected to an air guide pipe 31. The end of the air guide pipe 31 away from the humidity generator 3 passes through one side wall of the chamber body 1. The air guide pipe 31 and the chamber body 1 are fixedly connected.

[0035] refer to Figure 1 , Figure 2 and Figure 3 The box 1 has two partitions 2 fixed inside, which are vertically arranged and parallel to each other. Multiple second guide rails 23 are fixed on opposite sides of each partition 2, arranged vertically in sequence. Multiple support plates 42 are fixed on the side of the closed door facing the inner wall of the box 1, arranged vertically in sequence and horizontally arranged. The two ends of each support plate 42 are respectively embedded in the corresponding second guide rails 23 on the two partitions 2, and the support plates 42 and second guide rails 23 are slidably connected. One end of the air duct 31 inside the box 1 is fixed with a... The flow pipe 32 and the diversion pipe 32 are vertically arranged. The end of the diversion pipe 32 is closed. Multiple conveying pipes 33 are fixed on the diversion pipe 32. The multiple conveying pipes 33 are arranged in sequence along the length direction of the diversion pipe 32. The length direction of the conveying pipes 33 is perpendicular to the diversion pipe 32. The end of the conveying pipe 33 away from the diversion pipe 32 passes through the adjacent partition 2. The conveying pipes 33 and the partition 2 are fixedly connected. The conveying pipes 33 and the support plate 42 correspond one-to-one. The support plate 42 and the partition 2 are both made of thermal insulation material. Baffles 7 are fixed on the sides of the upper surface of the support plate 42. The baffles 7 are perpendicular to the support plate 42.

[0036] Multiple sets of heating elements 11 are fixed on the side wall of the housing 1 away from the closed door 4. The multiple sets of heating elements 11 are distributed at intervals in the vertical direction. The heating elements 11 correspond one-to-one with the support plate 42. Temperature sensors 21 and humidity sensors 22 are fixed on the partition plate 2 away from the conveying pipe 33. Multiple temperature sensors 21 and humidity sensors 22 are provided. The multiple temperature sensors 21 are distributed at intervals in the vertical direction. The temperature sensors 21 correspond one-to-one with the support plate 42. The humidity sensors 22 are distributed at intervals in the vertical direction. The humidity sensors 22 correspond one-to-one with the support plate 42.

[0037] Each of the four corners of the closed door 4 facing the box body 1 is fixed with a sliding rod 41. The length direction of the sliding rod 41 is perpendicular to the closed door 4. Each of the two opposite sides of the upper and lower inner walls of the box body 1 is fixed with a first guide rail 12. The length direction of the first guide rail 12 is parallel to the length direction of the sliding rod 41. One end of the sliding rod 41 is embedded in the first guide rail 12 and they correspond one-to-one. The sliding rod 41 and the first guide rail 12 are slidably connected.

[0038] When culturing multiple sets of specimens, the sealing door 4 is first pulled outward, causing it to move along the sliding rod 41 under the guidance of the first guide rail 12. Simultaneously, the support plate 42 moves outward along the second guide rail 23. Once the sealing door 4 reaches the set position, different specimens are placed on their respective support plates 42. Then, the sealing door 4 is pushed inward to reset the support plates 42. During this process, the baffle 7 prevents the specimens from slipping. When the sealing door 4 is fully closed to the chamber 1, the distal end of the support plate 42 is tightly fitted against the inner wall of the chamber 1, the sealing door 4 and the partition 2 abut against each other, and the two sides of the support plate 42 abut against the partition 2, forming multiple independent insulated chambers, placing each set of specimens in a different culture environment.

[0039] After activating multiple heating elements 11 and humidity generator 3, temperature sensor 21 monitors the temperature of each chamber in real time and automatically stops heating once the set value is reached. Simultaneously, the gas generated by humidity generator 3 enters the distribution pipe 32 via gas guide pipe 31, and is then distributed to different chambers via delivery pipes 33. Humidity sensor 22 continuously monitors the ambient humidity; when a chamber reaches the set humidity, the corresponding electrically controlled valve 34 closes to block airflow. Once all chambers meet the culture conditions, humidity generator 3 is turned off, thus achieving simultaneous culture of multiple specimens under different temperature and humidity conditions. Furthermore, the support plate 42 can be flexibly removed from the chamber 1 for easy specimen handling.

[0040] refer to Figure 1 , Figure 2 and Figure 4Fixed rods 6 are fixed at both ends of the closed door 4 on opposite sides. The length direction of the fixed rods 6 is perpendicular to the closed door 4. The side wall of the fixed rods 6 is provided with a snap-fit ​​groove 61. Housings 5 ​​are fixed at both ends of the box body 1 on opposite sides. The housing 5 is located at the end of the box body 1 near the opening. The end of the housing 5 facing the closed door 4 is open. A snap-fit ​​rod 51 is provided on the housing 5. The snap-fit ​​rod 51 is set vertically and slides through one side wall of the housing 5. The snap-fit ​​rod 51 and the snap-fit ​​groove 61 are snap-fitted and matched one-to-one. A limit plate 54 is provided inside the housing 5. The limit plate 54 is perpendicular to the snap-fit ​​rod 51 and the snap-fit ​​rod 51 passes through the limit plate 54. The locking rod 51 is fixedly connected to the limiting plate 54. A pull plate 52 is provided at the end of the locking rod 51 outside the housing 5. The pull plate 52 is perpendicular to the locking rod 51. The locking rod 51 passes through the pull plate 52 and is fixedly connected to the pull plate 52. The side of the locking rod 51 away from the pull plate 52 is set as an inclined surface. A spring 53 is fixed between the pull plate 52 and the housing 5. The spring 53 is sleeved on the outside of the locking rod 51. A brake rod 55 is rotatably connected to the end of the locking rod 51 outside the housing 5. The length direction of the brake rod 55 is perpendicular to the length direction of the locking rod 51. The pull plate 52 is located between the housing 5 and the brake rod 55. The housing 1 is fixed with overlapping plates 13 for overlapping the brake rod 55 at the housing 5.

[0041] As the closed door 4 moves toward the housing 1, it drives the fixed rod 6 to move. The fixed rod 6 gradually extends into the corresponding housing 5. As the end of the fixed rod 6 moves within the housing 5, it first contacts the inclined surface of the snap-fit ​​rod 51 and pushes the snap-fit ​​rod 51 away from the housing 5. The snap-fit ​​rod 51 drives the pull plate 52 to move, and the spring 53 is stretched. When the closed door 4 and the housing 1 come into contact, the snap-fit ​​groove 61 and the snap-fit ​​rod 51 align. The spring 53 releases its elasticity, driving the pull plate 52 to move toward the housing 5. The pull plate 52 drives the snap-fit ​​rod 51 to move, and the end of the snap-fit ​​rod 51 snaps into the snap-fit ​​groove 61, thus fixing the fixed rod 6 and the housing 5. This fixes the closed door 4 and the housing 1, making it difficult for the closed door 4 to move relative to the housing 1 during specimen culture.

[0042] After cultivation is complete, pull plate 52 is pulled away from shell 5. Pull plate 52 moves locking rod 51, which in turn moves limiting plate 54 and brake rod 55. When locking rod 51 disengages from locking groove 61, limiting plate 54 abuts against inner wall of shell 5, making locking rod 51 difficult to move further. At the same time, brake rod 55 is rotated and overlaps onto overlapping plate 13, releasing pull plate 52, making it difficult for pull plate 52 to move towards shell 5. This process moves all four pull plates 52, releasing the fixation of sealing door 4 and box 1. Pull sealing door 4 away from box 1. Sealing door 4 moves support plate 42. After support plate 42 moves to the set position, the cultured specimen is removed.

[0043] The implementation principle of the carbon dioxide incubator temperature and humidity control device in this application embodiment is as follows: When culturing multiple sets of specimens, the closed door 4 is moved away from the chamber 1. The closed door 4 drives the support plate 42 to move. After the support plate 42 moves to the set position, multiple sets of specimens are placed on different support plates 42. After placement, the closed door 4 is moved towards the chamber 1. The closed door 4 drives the support plate 42 and specimens to move. After the closed door 4 and the chamber 1 come into contact, the closed door 4 and the chamber 1 are fixedly connected by the snap-fit ​​rod 51 and the fixing rod 6. At the same time, the two partitions 2 and multiple support plates 42 jointly construct multiple independent heat preservation chambers. Multiple sets of specimens are in different heat preservation chambers. The heating element 11 and humidity generator 3 are activated. Under the coordinated control of the humidity sensor 22, temperature sensor 21 and electric control valve 34, each chamber can maintain different temperature and humidity conditions, thereby realizing the synchronous culture of multiple sets of specimens under different temperature and humidity conditions and improving the work efficiency of specimen culture.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
