Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide incubator technology, and more specifically, to a hot gas external door heated carbon dioxide incubator. Background Technology

[0002] A carbon dioxide incubator is an advanced cell culture device primarily used to provide a constant temperature (typically 37°C), humidity (95% RH), and CO2 concentration (typically 5%) environment for cells, tissues, or microorganisms.

[0003] When a carbon dioxide incubator is in operation, it is necessary to control the humidity and carbon dioxide concentration inside the chamber. In order to control the humidity and carbon dioxide concentration, carbon dioxide and moisture are added to the chamber. Commonly, moisture and carbon dioxide are added directly from the top of the chamber. However, there is a certain temperature difference between the moisture and carbon dioxide and the temperature inside the chamber. Directly adding moisture and carbon dioxide will affect the temperature inside the chamber, and thus affect the effect of cell or microbial culture. Therefore, a carbon dioxide incubator with a hot air external door is needed. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a hot air external door heated carbon dioxide incubator, which can effectively avoid the influence of supplemented air, steam and carbon dioxide on the air temperature around the culture dish, thereby improving the culture effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A hot air external door heated carbon dioxide incubator includes a chamber body. A door panel is hinged to the front of the chamber body. A suspended plate is fixedly connected to the inner wall of the chamber body. The suspended plate has equally spaced through slots. Two support bars are fixedly connected to the top of the suspended plate. A shelf is fixedly connected between the two support bars. Two air boxes are fixedly connected to the inner bottom wall of the chamber body. Both air boxes are L-shaped. A fan and an electric heating plate are fixedly connected to the inner wall of each air box. A temperature sensor, a humidity sensor, and a carbon dioxide sensor are installed on the inner wall of the chamber body. An exhaust pipe, an air inlet pipe, and a humidification pipe are connected to the back of the chamber body. The air inlet pipe and the humidification pipe are located below the suspended plate. Solenoid valves are installed on the exhaust pipe, the air inlet pipe, and the humidification pipe. A gas tank is connected to one end of the back of the air inlet pipe. A steam generator and an air pump are installed on the humidification pipe.

[0008] An observation opening is provided on the front of the door panel, and a transparent plate is fixedly connected to the inner wall of the observation opening.

[0009] As a further description of the above technical solution:

[0010] Heating rods arranged at equal intervals are fixedly connected to the inner wall of the observation port, and the back of the heating rods is in contact with the observation port.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the box is fixedly connected to a guide block, and a guide block is provided between the two guide blocks. The top of the guide block is fixedly connected to the inner wall of the box.

[0013] As a further description of the above technical solution:

[0014] The right side of the enclosure is fixedly connected to a controller that controls the fan, heating plate, solenoid valve, steam generator, and air pump. The outputs of the temperature sensor, humidity sensor, and carbon dioxide sensor are all connected to the controller.

[0015] As a further description of the above technical solution:

[0016] A filter plate is fixedly connected to the inner wall of the gas box, and the filter plate is located on one side of the heating plate.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This design uses a suspended plate to suspend the petri dishes in the middle of the chamber. By using an L-shaped air box in conjunction with a fan, the air at the top and bottom of the petri dishes can be circulated and heated, thereby improving the temperature uniformity inside the chamber. Moreover, the air, steam, and carbon dioxide entering the chamber are immediately drawn into the air box. After being heated by the heating plate, the air, steam, and carbon dioxide flow into the area around the petri dishes, effectively preventing the replenished air, steam, and carbon dioxide from affecting the temperature of the air around the petri dishes, thus improving the culture effect of the petri dishes.

[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 of the present utility model;

[0026] Please see Figure 1-4 In this utility model: a hot air external door heated carbon dioxide incubator includes a box body 1, a door panel 2 hinged to the front of the box body 1, a suspended plate 3 fixedly connected to the inner wall of the box body 1, through slots 301 arranged at equal intervals on the suspended plate 3, two support bars 4 fixedly connected to the top of the suspended plate 3, a shelf 5 fixedly connected between the two support bars 4, and two air boxes 6 fixedly connected to the inner bottom wall of the box body 1. The two air boxes 6 are both L-shaped, and air vents are fixedly connected to the inner walls of the two air boxes 6. The fan 7 and the heating plate 8 are installed. The inner wall of the box 1 is equipped with a temperature sensor 9, a humidity sensor 10 and a carbon dioxide sensor 11. The back of the box 1 is connected to an exhaust pipe 12, an air inlet pipe 13 and a humidification pipe 14. The air inlet pipe 13 and the humidification pipe 14 are located below the suspended plate 3. Solenoid valves 15 are installed on the exhaust pipe 12, the air inlet pipe 13 and the humidification pipe 14. One end of the back of the air inlet pipe 13 is connected to an air tank 16. A steam generator 17 and an air pump 23 are installed on the humidification pipe 14.

[0027] In this invention, the shelf 5 is used to place culture dishes for culturing cells. During use, the temperature sensor 9, humidity sensor 10, and carbon dioxide sensor 11 detect the temperature, humidity, and carbon dioxide content inside the chamber 1.

[0028] Users can control the carbon dioxide content inside the chamber 1 by opening the solenoid valves 15 on the exhaust pipe 12 and the intake pipe 13. After the solenoid valve 15 on the intake pipe 13 is opened, the carbon dioxide in the gas tank 16 will enter the chamber 1 through the intake pipe 13, and the air inside the chamber 1 will be discharged through the exhaust pipe 12, thereby increasing the carbon dioxide content inside the chamber 1.

[0029] After the user opens the solenoid valve 15 on the exhaust pipe 12 and the humidification pipe 14, the air pump 23 is turned on, which can input outside air into the box 1. The air inside the box 1 will be discharged from the exhaust pipe 12, thereby replacing the air inside the box 1. During the air replacement process, the steam generator 17 is turned on, and the steam generated by the steam generator 17 will enter the box 1 from the humidification pipe 14, thereby controlling the humidity inside the box 1.

[0030] Turning on the fan 7 and the heating plate 8 can control the temperature inside the cabinet 1. After the heating plate 8 is turned on, it will heat the air in the air box 6. Then the fan 7 will blow the heated air towards the inner top wall of the cabinet 1. After the hot air comes into contact with the inner top wall of the cabinet 1, it will be blocked and flow downward. Then the hot air will pass through the top of the shelf 5 and flow through the through groove 301 on the suspended plate 3 to the bottom of the cabinet 1. Then the air will be drawn back into the air box 6 for heating, thus realizing the circulation of air. During the air circulation, the inside of the cabinet 1 can be continuously heated, thereby keeping the internal temperature of the cabinet 1 stable and uniform.

[0031] Since the humidification pipe 14 and the air inlet pipe 13 are both located between the two air boxes 6, the air, steam and carbon dioxide entering the chamber 1 will be drawn into the air box 6 immediately. The air, steam and carbon dioxide will be heated by the heating plate 8 before flowing into the area around the petri dish, thus effectively avoiding the situation where the supplemented air, steam and carbon dioxide affect the air temperature around the petri dish, thereby improving the culture effect of the petri dish.

[0032] Furthermore, the use of air box 6 to circulate air between the bottom and top of chamber 1 can effectively prevent carbon dioxide from accumulating at the bottom of chamber 1, improve the uniformity of carbon dioxide concentration in chamber 1, and further enhance the culture effect of petri dishes.

[0033] Please see Figure 1 The door panel 2 has an observation opening 18 on its front side, and a transparent plate 19 is fixedly connected to the inner wall of the observation opening 18.

[0034] In this invention, the combined use of the observation port 18 and the transparent plate 19 makes it easier for users to observe the inside of the box 1, thereby improving the practicality of the device.

[0035] Please see Figure 1 The inner wall of the observation port 18 is fixedly connected with heating rods 20 arranged at equal intervals, and the back of the heating rods 20 is in contact with the observation port 18.

[0036] In this invention, the heating rod 20 can heat the door panel 2 and the transparent plate 19, effectively preventing the hot air inside the chamber 1 from condensing on the surface of the door panel 2 when the door panel 2 is opened. This effectively reduces the growth of bacteria on the surface of the door panel 2 and meets the requirements of the hot air external door heating carbon dioxide incubator.

[0037] Please see Figure 3 and 4 The inner wall of the housing 1 is fixedly connected to a guide block 21, and a guide block 22 is provided between the two guide blocks 21. The top of the guide block 22 is fixedly connected to the inner wall of the housing 1.

[0038] In this invention, the combined use of guide block 21 and guide block 22 can guide the air discharged towards the top wall of the box 1, allowing the air to flow evenly into the top of the shelf 5, enhancing the effect of air circulation around the shelf 5 and improving the practicality of the device.

[0039] Please see Figure 1 The right side of the housing 1 is fixedly connected to a controller 24 that controls the opening and closing of the fan 7, heating plate 8, solenoid valve 15, steam generator 17 and air pump 23. The output terminals of the temperature sensor 9, humidity sensor 10 and carbon dioxide sensor 11 are all connected to the controller 24.

[0040] In this invention, the controller 24 can receive data detected by the temperature sensor 9, humidity sensor 10 and carbon dioxide sensor 11, and send the data to the user. The user can conveniently and quickly control the fan 7, heating plate 8, solenoid valve 15, steam generator 17 and air pump 23 through the controller 24 to regulate the gas inside the box 1.

[0041] Please see Figure 3 Among them, a filter plate 25 is fixedly connected to the inner wall of the gas box 6, and the filter plate 25 is located on one side of the electric heating plate 8.

[0042] In this invention, the filter plate 25 can filter the air inside the housing 1, thereby improving the stability of the device.

[0043] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
