Description

Technical Field

[0001] This utility model relates to the field of bioengineering technology, specifically to an intestinal flora culture device. Background Technology

[0002] In order to maintain a good culture environment, intestinal bacteria are usually cultured in a constant temperature device. According to the search, Chinese patent announcement number CN208949303U discloses an intestinal flora culture device. Although the device has a simple structure, the internal conditions can be effectively monitored by thermometers and hygrometers, and the device can be adjusted in time. At the same time, filter cotton is installed in the air inlet and outlet pipes to ensure the culture environment of intestinal flora. The use of a constant temperature chamber can ensure the temperature stability during the culture of intestinal flora. However, when the device exchanges air through the air inlet and outlet pipes, when the external air temperature is low, cold air from the outside will enter the interior, resulting in low air temperature inside the device. This leads to unstable air temperature inside the device, which is not conducive to the culture of intestinal bacteria. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an intestinal flora culture device that solves the problem mentioned in the background art where the temperature difference between the external and internal airflows during ventilation leads to unstable temperature fluctuations in the internal airflow, which is detrimental to the culture of intestinal flora.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intestinal flora culture device, comprising a main body, a partition, a baffle, and a culture dish. A control device is installed on one side of the main body, and the control device is electrically connected to an electric heating plate on the bottom surface inside the main body. An exhaust fan is installed at the other end of the main body, and the exhaust fan is connected to the interior of the main body. An air inlet is provided on one side of the main body, and a filter plate is provided on the outside of the air inlet. The four ends of the filter plate are connected to the outer wall surface of the main body by screws. A baffle is provided inside one end of the main body, and the baffle is distributed on both sides of the partition. A culture dish is provided at the other end of the main body.

[0005] Preferably, the culture dish is placed on the surface of the support plate, one end of the support plate is welded to the inner wall of the device body, and there is a gap between the bottom of the support plate and the electric heating plate. The electric heating plate heats the inside of the device body, and the support plate helps to keep the culture dish away from the electric heating plate, avoiding direct contact between the culture dish and the electric heating plate.

[0006] Preferably, multiple baffles are provided, and the multiple baffles are arranged in a regular pattern with equal spacing, and adjacent baffles are arranged in a staggered pattern, which facilitates the circulation of air between the baffles.

[0007] Preferably, the partition is multi-folded and distributed between two adjacent baffles. The partition helps to separate the baffles into two meandering channels for air intake and exhaust, respectively. To improve the heat exchange efficiency of the baffles, they can be made of copper-aluminum composite material.

[0008] Preferably, both the partition and the baffle are made of transparent acrylic material, and the surface of the baffle near the culture dish is coated with a black coating, which helps to prevent the culture dish from being exposed to ultraviolet light for a long time, thus avoiding the impact on the intestinal bacteria culture.

[0009] Preferably, a lamp tube is provided between the baffle and the partition. The lamp tube is an ultraviolet lamp tube and is installed on one side of the base. A switch is provided on the surface of the base. During the air circulation process, the ultraviolet lamp tube will fully sterilize the air, thereby reducing the entry of external bacteria into the main body of the device.

[0010] This invention provides an intestinal flora culture device. It has the following beneficial effects:

[0011] (1) The intestinal flora culture device, when in use, intestinal flora are placed in a culture dish for culture. When ventilating, the air inside is exhausted by an exhaust fan. When the air is exhausted from the main body of the device, it will flow around the partition on one side and then be exhausted from the main body of the device. Then the external air will enter the main body of the device through the air inlet. Then the airflow entering the main body of the device will flow around the other side of the partition. During the flow, the air entering the main body of the device will conduct heat with the air exiting the main body of the device through the partition, thereby exchanging heat with each other. The temperature of the air exiting the main body of the device will decrease and the temperature of the air entering the main body of the device will increase. This helps to reduce the temperature difference between the external air entering the main body of the device, and thus helps to maintain the stability of the internal temperature of the main body of the device when the external temperature is low.

[0012] (2) In this intestinal flora culture device, the air entering the device body can circulate in a roundabout manner at one end of the device body under the action of baffles and partitions, thereby prolonging the journey of the air into the device body. During the circulation process, the ultraviolet lamp will fully sterilize the air, thereby reducing the entry of external bacteria into the device body.

[0013] This solves the problem that existing devices have a temperature difference between the external and internal airflows during ventilation, which leads to unstable temperature fluctuations in the internal airflow, making it unfavorable for the cultivation of intestinal bacteria.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Example 1:

[0023] Please see Figure 1-6This utility model provides a technical solution: an intestinal flora culture device, including a device body 1, a partition 5, a baffle 6, and a culture dish 8. A control device 2 is installed on one side of the device body 1, and the control device 2 is electrically connected to the electric heating plate 4 on the bottom surface of the device body 1. An exhaust fan 3 is installed at the other end of the device body 1, and the exhaust fan 3 is connected to the interior of the device body 1. An air inlet 13 is opened on one side of the device body 1, and a filter plate 12 is arranged on the outside of the air inlet 13. The four ends of the filter plate 12 are connected to the outer wall surface of the device body 1 by screws. A baffle 6 is arranged inside one end of the device body 1, and the baffle 6 is distributed on both sides of the partition 5. A culture dish 8 is arranged at the other end of the device body 1, and the culture dish 8 is placed on the surface of a support plate 7. One end of the support plate 7 is welded to the inner wall of the device body 1, and there is a gap between the bottom of the support plate 7 and the electric heating plate 4. Multiple baffles 6 are arranged in a regular pattern with equal spacing, and adjacent baffles 6 are arranged in a staggered left-right pattern. The partition 5 is multi-folded and distributed between two adjacent baffles 6. When the device is in use, intestinal bacteria are placed inside the culture dish 8 for cultivation. During ventilation, the exhaust fan 3 exhausts the internal air. When the air is exhausted from the device body 1, it flows left and right along one side of the partition 5, thus exiting the device body 1. Then, the external air enters the device body 1 through the air inlet 13. The airflow entering the device body 1 then flows left and right along the other side of the partition 5. During the flow, the air entering the device body 1 and the air exiting the device body 1 conduct heat through the partition 5, thus exchanging heat with each other. This causes the temperature of the air exiting the device body 1 to decrease and the temperature of the air entering the device body 1 to increase. This helps to reduce the temperature difference between the external air entering the device body 1 and the internal temperature of the device body 1, thus helping to maintain the stability of the internal temperature of the device body 1 when the external temperature is low.

[0024] Example 2:

[0025] Both the partition 5 and the baffle 6 are made of transparent acrylic. The surface of the baffle 6 near the petri dish 8 is coated with a black coating. A lamp tube 11 is installed between the baffle 6 and the partition 5. The lamp tube 11 is an ultraviolet lamp tube 11 and is installed on one side of the base 10. A switch 9 is installed on the surface of the base 10. The air entering the device body 1 can circulate in a roundabout manner at one end of the device body 1 under the action of the baffle 6 and the partition 5, thereby prolonging the journey of the air into the device body 1. During the circulation process, the ultraviolet lamp tube 11 will fully sterilize the air, thereby reducing the entry of external bacteria into the device body 1.

[0026] Working principle: When the device is in use, intestinal bacteria are placed inside the culture dish 8 for cultivation. During ventilation, the exhaust fan 3 exhausts the internal air. As the air exits the device body 1, it flows left and right along one side of the partition 5, thus exiting the device body 1. During the circulation process, the air entering the device body 1 and the air exiting the device body 1 conduct heat through the partition 5, thereby exchanging heat with each other. This helps to reduce the temperature difference between the external air entering the device body 1 and the external air entering the device body 1. At the same time, the ultraviolet lamp 11 will thoroughly sterilize the air during the circulation process.
