[0029] Carbon dioxide is a common compound in the air. A carbon dioxide molecule is composed of two oxygen atoms and one carbon atom through a covalent bond. It is a colorless and odorless gas at room temperature. Its density is greater than that of air. It can dissolve in water and react with water to produce carbonic acid. It does not support combustion. The carbon dioxide incubator is an advanced instrument for culturing cells, tissues, and bacteria. It is a key equipment necessary for immunology, oncology, genetics, and bioengineering. The carbon dioxide incubator is improved on the basis of ordinary culture. It is mainly a device that can add carbon dioxide to meet the environment required for culturing microorganisms to culture biological cells or tissues in vitro.

[0030] In specific application scenarios, a growth environment similar to that of cells / tissues in a living body is simulated in a CO2 incubator, which requires a stable temperature, a stable CO2 concentration level, and a high relative saturated humidity. However, the existing CO2 incubators on the market mainly provide heating and CO2 supply functions, and cannot guarantee the humidity inside the incubator.

[0031] Based on this, an embodiment of the present application provides a carbon dioxide incubator, which provides an internal culture chamber environment with a stable temperature, a stable carbon dioxide concentration level and a high relative saturated humidity through a carbon dioxide supply device, a water supply device and a heating device.

[0032] The carbon dioxide incubator is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a carbon dioxide incubator provided in an embodiment of the present application. Figure 2 A cross-sectional schematic diagram of a carbon dioxide incubator provided in an embodiment of the present application.

[0034] The embodiment of the present application provides a carbon dioxide incubator, comprising: a box body 100, wherein a culture cavity 110 is formed inside the box body 100, and an inner wall of the culture cavity 110 is provided with an air vent 111 and a heat dissipation hole 112; a carbon dioxide supply device, wherein the carbon dioxide supply device is connected to the culture cavity 110 through the air vent 111 to transmit carbon dioxide gas; a water supply device, comprising a water tank 114, wherein a liquid through hole 113 is provided in the water tank 114, and the water supply device is connected to the water tank 114 through the liquid through hole 113 to transmit liquid water; and a heating device, wherein the heating device heats the culture cavity 110 through the heat dissipation hole 112.

[0035] It should be noted that a culture chamber 110 is formed inside the housing 100, providing a controlled environment for the culture of cells or microorganisms. The vents 111 and the heat dissipation holes 112 help to adjust the gas environment and temperature in the incubator. The vents 111 allow fresh air to enter the culture chamber 110, and can also be used to connect a carbon dioxide supply device to supply carbon dioxide gas. The heat dissipation holes 112 are used to dissipate the heat inside the culture chamber 110 to maintain a suitable temperature. The liquid hole 113 is arranged on the surface of the water tank 114, which is used to circulate liquid water to ensure the air humidity inside the culture chamber. The carbon dioxide supply device is connected to the culture chamber 110 through the vents 111, and is used to transmit carbon dioxide gas to ensure that the carbon dioxide concentration in the incubator is at a desired level to simulate a specific biological environment. The water supply device is used to transmit liquid water to the water tank 114 of the culture chamber 110. The heating device heats the culture chamber 110 through the heat dissipation holes 112 to ensure that the temperature inside the incubator is stable and suitable for the growth of cells or microorganisms.

[0036] It is understandable that the carbon dioxide supply device generally includes a gas container, a pressure regulator, a pipe and a connector. The gas is transported from the container to the incubator through a pipe and released into the culture chamber 110 through the vent 111. The pressure regulator can ensure that the flow rate and pressure of carbon dioxide are within an appropriate range. The water supply device generally includes a water tank 114 or a water tank, a pipe and a connector. Water is pumped or drained from the water tank 114 through the liquid hole 113 and transported to the culture chamber 110 in the incubator. In some cases, the water supply device may be equipped with a water level sensor or regulator to ensure that the supply amount and frequency of the water liquid meet the requirements. The heating device sends cold air or warm air into the pipe, which is transmitted by the pipe to the heat dissipation hole 112, and then flows into the culture chamber 110 from the heat dissipation hole 112, thereby controlling the temperature conditions inside the culture chamber 110.

[0037] In one embodiment of the present application, a carbon dioxide incubator body 100 forms a culture chamber 110 inside. A carbon dioxide supply device, a water supply device, and a heating device are provided to control the environmental conditions of the temperature, humidity, and carbon dioxide concentration inside the culture chamber 110, respectively. The carbon dioxide supply device delivers the carbon dioxide to the incubator through a carbon dioxide pipe 140, and releases the carbon dioxide into the culture chamber 110 through a vent 111. The water supply device delivers the carbon dioxide to the incubator through a water pipe 160, and flows into a water tank 114 in the culture chamber 110 through a liquid hole 113. The heating device delivers hot air or cold air to the incubator through a heat pipe 150, and releases heat into the culture chamber 110 or takes away the heat in the culture chamber 110 through the heat dissipation holes 112.

[0038] Reference Figure 3 As shown, Figure 3This is a structural schematic diagram of a carbon dioxide incubator in a closed state provided in an embodiment of the present application. A control panel 121 is provided on the surface of the box body 100, and a carbon dioxide supply device, a water supply device and a heating device are all electrically connected to the control panel 121.

[0039] It should be noted that the control panel 121 is the main interface for the user to interact with the incubator. Through the control panel 121, the user can monitor the key parameters in the culture chamber 110 in real time and adjust the operation of the carbon dioxide supply device, water supply device and heating device as needed.

[0040] It is understandable that the control panel 121 displays parameters such as the current temperature, humidity and carbon dioxide concentration. In this way, the user can understand the status of the culture environment at a glance. By clicking on the control panel 121, the user can choose to adjust the operating status of the carbon dioxide supply device, the water supply device and the heating device, such as increasing or decreasing the carbon dioxide supply, adjusting the temperature of the heating device, etc. The control panel 121 may also be provided with an indicator light to indicate the operating status of each functional component, such as whether the carbon dioxide supply device, the water supply device and the heating device are operating normally. The control panel 121 may also be equipped with an alarm system for sounding an alarm when key parameters exceed a safe range. For example, when the temperature is too high or the carbon dioxide concentration is abnormal, the alarm system will automatically sound an alarm to remind the user to make corresponding adjustments or take measures.

[0041] In some embodiments, the box 100 is provided with a carbon dioxide concentration sensor and a temperature and humidity sensor, and both the carbon dioxide concentration sensor and the temperature and humidity sensor are electrically connected to the control panel 121 .

[0042] It should be noted that the carbon dioxide sensor can detect the carbon dioxide concentration level in the culture chamber 110. According to the detected concentration, the control panel 121 can adjust the operation of the carbon dioxide supply device to maintain the desired carbon dioxide concentration level. This is very important for simulating a specific biological environment, especially for biological experiments that require a specific carbon dioxide concentration. The temperature and humidity sensor can monitor the temperature and humidity in the culture chamber 110 in real time. By cooperating with the heating device and the water supply device, the control panel 121 can adjust the operation of the heating device and the water supply device according to the feedback from the sensor to maintain the desired temperature and humidity levels. This is essential for maintaining a good growth environment for cells or microorganisms.

[0043] Reference Figure 2 As shown, in some embodiments, the ventilation holes 111 and the heat dissipation holes 112 are evenly distributed in an array on the inner wall surface of the culture chamber 110 , and the water tank 114 is disposed at the bottom of the culture chamber 110 .

[0044] It should be noted that the vents 111 and the heat dissipation holes 112 are arranged in an array on the inner wall surface to form a rhombus, which is used to circulate gas to ensure the concentration of carbon dioxide in the culture chamber 110 and promote the dissipation of heat. The water tank 114 is set at the bottom of the culture chamber 110 to accommodate and supply water liquid to ensure the air humidity in the chamber. Through such a structural design, the culture chamber 110 can provide a closed and stable environment to meet the needs of biological growth and experiments. The reasonable arrangement of components such as the vents 111, the heat dissipation holes 112 and the water tank 114 ensures that the ventilation, temperature and humidity inside the chamber are in a suitable state.

[0045] It is understandable that the sealing design is very important because the culture chamber 110 needs to provide a stable growth environment. Considering the requirements of biological culture, the material selection of the culture chamber 110 is very important. Usually, non-toxic and corrosion-resistant materials such as stainless steel or special plastics are selected to ensure the purity and biosafety of the culture environment.

[0046] Reference Figure 4 As shown, Figure 4 for Figure 1 Schematic diagram of the structure of the middle guide column. In some embodiments, the carbon dioxide incubator further includes a plurality of guide columns 115 , which extend in the vertical direction and are symmetrically arranged on both sides of the culture chamber 110 .

[0047] It should be noted that the multiple guide pillars 115 are symmetrically arranged on both sides of the culture chamber 110, so that the user can easily fix the culture equipment or sample rack at a specific position, facilitate operation and observation of changes in the culture process, and improve the controllability and repeatability of the experiment.

[0048] In one embodiment of the present application, four guide pillars 115 are respectively fixed on two sides close to four corners of the culture chamber 110 , and the four guide pillars 115 are symmetrical in pairs and are respectively arranged on the surfaces of the two side walls.

[0049] Reference Figure 4 As shown, in some embodiments, a plurality of hook portions 1151 are arranged on the surface of the guide column 115 along its extension direction, and the carbon dioxide incubator further includes a plurality of supporting plates 116 for placing culture dishes, and the supporting plates 116 are fixedly mounted on the hook portions 1151 .

[0050] It should be noted that the support plate 116 is fixedly mounted on the hook portion 1151, which can ensure that the culture dish is firmly placed on the support plate 116. This can prevent the culture dish from accidentally moving or shaking during the culture process, and ensure the accuracy and repeatability of the experiment. The user can freely adjust the position and number of the mounting support plate 116 as needed to adapt to different types of culture experiments or culture utensils of different specifications. This design provides greater flexibility, allowing the incubator to cope with diverse experimental needs. The design of providing a hook portion 1151 on the surface of the guide column 115 and fixing the support plate 116 improves the practicality and flexibility of the carbon dioxide incubator, and provides a more convenient and efficient culture environment for scientific researchers.

[0051] Reference Figure 1 As shown, in some embodiments, the box body 100 is movably connected to a box door 120 to open and close the box body 100.

[0052] It should be noted that the door 120 is provided so that the user can conveniently open or close the incubator, and is convenient for placing or removing culture equipment, samples, etc. This convenient operation can save the user's time and energy and improve the efficiency of the experiment. The door 120 has good sealing performance, which can effectively prevent temperature fluctuations and the influence of the external environment and provide a stable culture environment. This is particularly important for some biological culture experiments that are sensitive to temperature.

[0053] In one embodiment of the present application, the box body 100 is opened or closed by pulling or pushing the box door 120. The control panel 121 is arranged on the surface of the box door 120. After closing the box door 120, the culture chamber 110 is ensured to be in a closed state. The control panel 121 displays the temperature and humidity index and carbon dioxide concentration detected by the sensor, and can also check the operating status of the carbon dioxide supply device, the water supply device and the heating device, and control the carbon dioxide supply device, the water supply device and the heating device to switch the working mode.

[0054] Reference Figure 5 As shown, Figure 5 This is a structural schematic diagram of a carbon dioxide incubator in an open state provided in an embodiment of the present application. In some embodiments, an observation panel 130 is further provided between the box body 100 and the door 120, and one end of the observation panel 130 is hinged to the box body.

[0055] It should be noted that the observation panel 130 is the door of the culture chamber 110, and the culture chamber 110 is opened by opening the observation panel 130. The movable connection design of the observation panel 130 allows the user to conveniently open or close the culture chamber 110 for observation, operation or sampling. This convenient operation can improve the efficiency and accuracy of the experiment.

[0056] Reference Figure 5As shown, in some embodiments, the viewing panel 130 is made of visualization glass.

[0057] It should be noted that the observation panel 130 allows the user to observe the situation inside the culture chamber 110 in real time without opening it, thereby avoiding unnecessary impact on the culture environment. This is of great significance for monitoring changes in cell growth, colony morphology, etc. The user can directly observe the state of the culture dish through the observation panel 130, which is convenient for judging the progress of the experiment and adjusting experimental parameters, such as CO2 concentration, temperature, etc., so as to more accurately control the experimental conditions. The design of the box 100 provided with the observation panel 130 greatly improves the practicality and safety of the carbon dioxide incubator, and provides scientific researchers with an efficient culture environment that is easy to observe, operate and control.

[0058] Reference Figure 5 As shown, in some embodiments, the opening direction of the cabinet door 120 is opposite to the opening direction of the observation panel 130.

[0059] It should be noted that if the door 120 and the observation panel 130 are opened in the same direction at the same time, it may cause spatial conflicts and limit the flexibility of the user during operation. By opening in opposite directions, the internal space of the incubator can be utilized to the greatest extent, which is convenient for the user to operate and take samples. In addition, if the door 120 and the observation panel 130 are opened in the same direction at the same time, the risk of collision or accident during operation may be increased. Opposite opening directions can reduce this risk and improve the safety of operation.
