Description

Technical Field

[0001] This utility model relates to the field of microbial research technology, specifically a porous microbial aeration culture dish. Background Technology

[0002] Microbial petri dishes are basic experimental instruments used for the cultivation and observation of microorganisms. They are usually made of transparent material, either round or square. Microbial petri dishes are widely used in many fields such as microbiology research, medical testing, and food hygiene inspection. Researchers or laboratory personnel can inoculate microorganisms onto the culture medium in the petri dish and cultivate them under suitable conditions. They can observe the growth status and morphological characteristics of the microorganisms, and perform operations such as microbial isolation, purification, and counting to gain a deeper understanding of the biological characteristics of microorganisms and related research content.

[0003] Traditional petri dishes have relatively simple structures and certain functional limitations. In terms of temperature control, they usually rely solely on the temperature of the external environment. When the external temperature is unstable or does not meet the requirements for microbial growth, it will affect the normal growth and reproduction of microorganisms, thereby affecting the accuracy and reliability of experimental results. Moreover, the design of traditional petri dishes is not perfect in terms of air exchange and prevention of external impurities. While ensuring that the microorganisms inside the petri dish can breathe normally, it is difficult to effectively block the entry of external impurities such as dust and bacteria, which may contaminate the cultured microorganisms and interfere with the experimental process. Therefore, we propose a porous, breathable microbial petri dish. Utility Model Content

[0004] One of the technical problems this application aims to solve is: addressing the issue that traditional petri dishes rely excessively on the external environment during use, which affects their normal growth due to factors such as temperature and air exchange.

[0005] To address the aforementioned technical problems, this application provides a porous microbial aerated culture dish, comprising a culture dish body, a culture dish base, a culture dish lid at the upper end of the culture dish base, a culture dish groove on one side surface of the culture dish base, six culture dish grooves arranged in a linear array, a flow chamber fixedly connected to the lower end of the culture dish base, and a groove seal fixedly connected to one side surface of the culture dish lid.

[0006] Preferably, the culture dish cap has six evenly distributed linear arrays, one side edge of the culture dish cap and the upper edge of the culture dish are both rounded, and the lower end of the culture dish cap and the upper end of the culture dish are mutually adapted.

[0007] Preferably, a flow channel is provided between the inner side of the flow chamber and the outer side of the culture dish tank, and an opening is provided on both sides of the flow channel, with a plastic soft plug snapped into the inner side of the opening.

[0008] Preferably, a vent hole is provided on one side of the vessel cap, an upper air filter membrane is fixedly connected to the upper end of the vent hole, a lower air filter membrane is provided at the lower end of the upper air filter membrane, and the lower air filter membrane is fixedly connected to the lower end of the vent hole.

[0009] Preferably, a ventilation groove is provided on the upper side of the ventilation hole, and air exchange grooves are provided on both sides of the petri dish lid, and the air exchange grooves and the ventilation grooves are interconnected.

[0010] Preferably, the upper end of the petri dish lid is provided with a snap-fit ​​groove, which is adapted to the lower end of the flow chamber, and auxiliary grooves are provided on both sides of the snap-fit ​​groove, which are adapted to one side of the plastic soft stopper.

[0011] This utility model has at least the following beneficial effects:

[0012] This invention utilizes a flow chamber located at the lower end of the petri dish base and a flow channel between the petri dish tank and the outside of the petri dish tank, along with open openings on both sides and snap-fit ​​plastic plugs, to achieve effective temperature control inside the petri dish. The plastic plugs can be removed from the open openings according to the specific needs of the microorganisms, allowing the open openings to connect with the flow channel. This facilitates the easy injection of a flowing liquid with a certain temperature into the flow channel. During the flow process, the liquid transfers heat to the petri dish tank, creating a suitable growth temperature environment for the microorganisms. This eliminates the dependence of traditional petri dishes on ambient temperature, providing stable temperature conditions for microorganisms regardless of external temperature changes. This effectively improves the success rate of microbial culture and the accuracy of experimental results, providing a reliable guarantee for microbiological research and related experiments.

[0013] This invention utilizes a ventilation hole on one side of the petri dish lid, along with upper and lower air filter membranes fixed to the upper and lower ends of the ventilation hole, to form an effective protective barrier. While ensuring air exchange between the petri dish and the outside environment, the two air filter membranes filter out dust, bacteria, and other impurities from the air, reducing the impact of external impurities on the petri dish and creating a relatively pure growth environment for microorganisms. Furthermore, the ventilation groove on the upper side of the ventilation hole connects with the ventilation grooves on both sides of the petri dish lid, further facilitating air exchange inside the petri dish. This allows microorganisms to obtain sufficient fresh air, promoting their normal growth and metabolism, improving the practicality and reliability of the petri dish, and providing strong support for the smooth conduct of microbial culture experiments.

Detailed Implementation

[0020] 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. Example

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a porous microbial aerated culture dish, including a culture dish body 1, a culture dish base 2, a culture dish cover 3 at the upper end of the culture dish base 2, a culture dish groove 4 on one side surface of the culture dish base 2, six culture dish grooves 4 are arranged in a linear array and evenly distributed, the six culture dish grooves 4 are arranged in two rows, with three in each row, a flow chamber 5 is fixedly connected to the lower end of the culture dish base 2, and a groove sealing cover 9 is fixedly connected to one side surface of the culture dish cover 3.

[0022] The petri dish cover 9 has six evenly distributed linear arrays. One side edge of the petri dish cover 9 and the upper edge of the petri dish 4 are both rounded. The rounded corner design makes the petri dish cover 9 and the petri dish 4 more compact when they are joined together, reducing gaps. At the same time, when the two are separated, it can effectively avoid the occurrence of contact, effectively improving the practicality of the overall device. The lower end of the petri dish cover 9 and the upper end of the petri dish 4 are mutually compatible.

[0023] A flow channel 6 is provided between the inner side of the flow chamber 5 and the outer side of the culture dish 4. Openings 7 are provided on both sides of the flow channel 6. Plastic soft plugs 8 are snapped onto the inner side of the openings 7. The plastic soft plugs 8 are used to control the opening and closing state of the openings 7. The plastic soft plugs 8 are removed from the openings 7, so that the openings 7 and the flow channel 6 are interconnected. The flow liquid with a certain temperature can be injected into the interior of the flow channel 6 through one of the openings 7 and finally discharged through the other opening 7. Alternatively, the flow liquid with a certain temperature can be directly injected into the interior of the flow channel 6 and sealed with the two plastic soft plugs 8. After use, it can be cleaned and discharged.

[0024] A vent hole 10 is provided on one side of the petri dish cover 9. An upper air filter membrane 11 is fixedly connected to the upper end of the vent hole 10, and a lower air filter membrane 12 is provided at the lower end of the upper air filter membrane 11. The lower air filter membrane 12 is fixedly connected to the lower end of the vent hole 10. The two layers of air filter membranes can effectively ensure that the interior of the petri dish 4 can breathe while minimizing the impact of external impurities on its interior when the whole is stored statically.

[0025] A ventilation groove 13 is provided on the upper side of the ventilation hole 10, and a ventilation groove 14 is provided on both sides of the petri dish lid 3. The ventilation groove 14 and the ventilation groove 13 are interconnected. By using the ventilation groove 13 and the ventilation groove 14 together, the air exchange inside the whole can be effectively facilitated.

[0026] The upper end of the petri dish lid 3 is provided with a snap-fit ​​groove 15, which is adapted to the lower end of the flow chamber 5. After the petri dish lid 3 is removed from the upper end of the petri dish base 2, the petri dish lid 3 can be fixed to the lower end of the petri dish base 2 by using the cooperation between the inside of the snap-fit ​​groove 15 and the lower end of the flow chamber 5. This increases the overall convenience of operation and prevents the petri dish lid 3 from being lost or damaged. The two sides of the snap-fit ​​groove 15 are provided with auxiliary grooves 16, which are adapted to one side of the plastic soft plugs 8. When the petri dish lid 3 is placed at the lower end of the flow chamber 5, the two plastic soft plugs 8 are snapped and fixed inside the auxiliary grooves 16, which stabilizes the overall placement and connection.

[0027] When this porous, aerated microbial culture dish is in operation, the six culture slots 4 on the culture dish base 2 are used to place microorganisms. The corresponding slot caps 9 on the culture dish lid 3 have rounded corners, ensuring a tight fit and preventing separation, thus achieving a seal and preventing leakage of microorganisms from the culture slots 4. The flow channel 6 between the flow chamber 5 at the lower end of the culture dish base 2 and the culture slots 4, through the opening 7 and the plastic soft stopper 8, allows for controlled liquid flow. Users can inject flowing liquid to adjust the temperature or seal the liquid for later cleaning. The vent holes 10 on the slot caps 9 and the two layers of air filters at their upper and lower ends ensure that the culture slots 4 can breathe while stationary and reduce the entry of impurities. The ventilation slots 13 and 14 work together to facilitate internal air exchange, ensuring the necessary airflow for breathing. The snap-fit ​​slots 15 on the culture dish lid 3 engage with the lower end of the flow chamber 5 to secure the removed culture dish lid 3 to the lower end of the culture dish base 2, preventing loss or damage. The auxiliary grooves 16 on both sides can lock and fix the plastic soft plug 8 when the petri dish lid 3 is placed, thus stabilizing the whole.
