Description

Technical Field

[0001] This utility model relates to the field of petri dish technology, specifically to a food microbial detection petri dish. Background Technology

[0002] Petri dishes are used to cultivate and analyze microorganisms in food. They are typically sterile plastic or glass dishes filled with agar medium, which provides the nutrients necessary for microbial growth. By inoculating food samples and culturing them at a suitable temperature, colonies will grow, allowing for the counting and identification of pathogenic or indicator bacteria, and the assessment of food hygiene and safety.

[0003] Existing petri dishes used for food testing, such as the one disclosed in patent publication number CN221822155U, are multi-control compartment culture containers. These containers are divided into multiple control compartments by several partitions. The use of annular rubber pads and multiple L-shaped rubber pads ensures that the culture medium does not leak into adjacent control compartments, allowing each control compartment to independently culture food microorganisms. The top of the circular rubber pad and the outer side of the strip rubber pad fit tightly against the inner wall of the circular clearance groove, sealing the space between the partitions and the top of the lid's inner wall, preventing the culture medium in one control compartment from spilling into adjacent control compartments when the petri dish is shaken. In practical use, the culture medium requires a suitable ambient temperature to improve its culturing effect. However, existing technologies only use the petri dish for culturing in a conventional environment, failing to achieve the required suitable temperature, leading to a reduction in culturing effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a food microbial testing petri dish to solve the technical problem that existing technologies only use the dish body to cultivate culture medium in a conventional environment, which cannot achieve suitable environmental temperatures, resulting in reduced cultivation effects.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A food microbial testing petri dish includes a dish body and a lid. The bottom surface of the dish body is provided with a bottom frame and a rotating shell. A locking component is provided inside the rotating shell. A battery slot is provided at the bottom of the locking component. A battery pack is provided in the battery slot. A control switch is provided on the bottom surface of the rotating shell. A constant temperature plate is provided through the side wall of the rotating shell. One end of the constant temperature plate extends into the locking component, and the other end is located on the bottom surface of the dish body. The constant temperature plate is electrically connected to the battery pack.

[0007] A further technical solution is that the locking assembly includes a locking cylinder, the top end of which passes through the rotating shell and is fixed to the bottom surface of the dish body. A telescopic rod is connected to the top surface of the inner cavity of the locking cylinder. A spring is sleeved on the upper part of the telescopic rod. The bottom end of the spring is connected to the lower top surface of the telescopic rod. The bottom end of the telescopic rod is rotatably connected to the top surface of the battery slot. One end of the constant temperature plate extends into the through groove of the locking cylinder and engages with the through groove.

[0008] A further technical solution is that the control switch is provided on the bottom surface of the rotating shell.

[0009] A further technical solution is that the constant temperature plate corresponds to multiple areas on the bottom surface of the dish after rotation.

[0010] A further technical solution is that the dish body is provided with a first fixing column, the first fixing column is provided with multiple isolation plates, the isolation plates divide the dish body into multiple culture zones, and the dish lid faces each culture zone and covers the top of the dish body.

[0011] A further technical solution is that a second fixing post is provided inside the lid of the dish, and the second fixing post is provided with a top plate connected to the top surface of the isolation plate, and the top plate is tightly connected to the top surface of the isolation plate.

[0012] A further technical solution is that the bottom surface of the top plate is provided with a first magnetic sheet, and the top surface of the isolation plate is provided with a second magnetic sheet, and the first magnetic sheet and the second magnetic sheet are magnetically connected.

[0013] A further technical solution is that the top surface of the lid is provided with a gripping block.

[0014] A further technical solution is that the isolation plate and the dish body, as well as the top plate and the dish lid, are all integrally connected, wherein the bottom edge of the isolation plate extends into the dish body to insulate the multiple culture zones.

[0015] A further technical solution is to provide multiple micro-breathing holes on the side of the lid.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Place the culture medium into the dish and cover it with the lid. Then, observe the mixing temperature to determine if heating of the dish is necessary. If the current ambient temperature is lower than the required temperature for the culture medium, activate the control switch to power the thermostat via the battery pack. The thermostat is then stabilized at the bottom of the dish by the locking mechanism, providing the required incubation temperature for the culture medium. This solves the technical problem of existing technologies that rely solely on dishes in a conventional environment for culture, which cannot achieve suitable ambient temperatures, leading to reduced culture effectiveness.

[0018] 2. Multiple culture zones allow for the simultaneous cultivation of multiple culture media. The heat insulation provided by the partition plate prevents heat transfer from one culture zone to another, thus avoiding disruption to normal cultivation. Furthermore, the magnetic connection between the top plate and the partition plate enhances the sealed environment, and the micro-breathing holes in the dish lid improve the epoxy function, thereby improving the cultivation effect of the culture medium.

[0025] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0026] See Figures 1 to 5 This utility model provides a food microbial testing petri dish, including a dish body 1 and a dish lid 2. The bottom surface of the dish body 1 is provided with a bottom frame 3 and a rotating shell 4. The rotating shell 4 is provided with a locking component. The bottom of the locking component is provided with a battery slot 5. The battery slot 5 is provided with a battery pack 8. The bottom surface of the rotating shell 4 is provided with a control switch 6. A constant temperature plate 7 is provided through the side wall of the rotating shell 4. One end of the constant temperature plate 7 extends into the locking component, and the other end is located on the bottom surface of the dish body 1. The constant temperature plate 7 is electrically connected to the battery pack 8.

[0027] It should be noted that the constant temperature plate 7 uses a PTC constant temperature heating plate. When it is initially powered on, the temperature is low, the resistance is low, the current is high, and the heating is rapid. When the temperature rises to a certain value, the resistance increases sharply, causing the current to decrease sharply and the heating power to drop. When the heat generation and dissipation are balanced, the temperature automatically stabilizes near that point, achieving self-temperature control. This ensures that the constant temperature plate 7 can maintain a constant temperature for the culture medium during the cultivation period, improving cultivation efficiency.

[0028] Specifically, the culture medium is placed in dish 1, and dish lid 2 is placed over dish 1. Then, depending on the observed temperature, it is determined whether dish 1 needs to be heated. If the current ambient temperature is lower than the required temperature for the culture medium, control switch 6 is activated, powering the thermostat 7 via battery pack 8. The thermostat 7 is then stabilized at the bottom of dish 1 by the locking mechanism, providing the required incubation temperature for the culture medium within dish 1. This solves the technical problem in existing technologies where culture medium is cultured in a conventional environment using dish 1, which cannot achieve the desired temperature, leading to reduced culture effectiveness.

[0029] Preferably, the dish body 1 is provided with a first fixing column 13, the first fixing column 13 is provided with multiple isolation plates 14, the isolation plates 14 divide the dish body 1 into multiple culture zones, and the dish lid 2 faces each culture zone and covers the top of the dish body 1.

[0030] In this embodiment, the internal area of ​​the dish 1 is divided into multiple culture zones by the partition plate 14, which can accommodate multiple culture media for cultivation at the same time, thereby improving the cultivation efficiency of the culture media.

[0031] Preferably, the lid 2 is provided with a second fixing post 15, and the second fixing post 15 is provided with a top plate 16 connected to the top surface of the isolation plate 14, and the top plate 16 is tightly connected to the top surface of the isolation plate 14.

[0032] In this embodiment, the top plate 16 is adapted to the isolation plate 14 to seal and isolate the space of each culture area, so as to avoid cross-infection when cultivating multiple culture media at the same time.

[0033] Furthermore, the bottom surface of the top plate 16 is provided with a first magnet piece 19, and the top surface of the isolation plate 14 is provided with a second magnet piece 20. The first magnet piece 19 and the second magnet piece 20 are magnetically connected.

[0034] In this embodiment, the top plate 16 and the isolation plate 14 are stably connected by magnetic attraction between the first magnet 19 and the second magnet 20. This also improves the airtightness of the culture area.

[0035] Furthermore, the top surface of the lid 2 is provided with a gripping block 17. This facilitates gripping the lid 2 to separate it from or cover the dish body 1.

[0036] Preferably, the locking assembly includes a locking cylinder 9, the top end of which passes through the rotating shell 4 and is fixed to the bottom surface of the dish body 1. A telescopic rod 10 is connected to the top surface of the inner part of the locking cylinder 9. A spring 11 is sleeved on the upper part of the telescopic rod 10. The bottom end of the spring 11 is connected to the lower top surface of the telescopic rod 10. The bottom end of the telescopic rod 10 is rotatably connected to the top surface of the battery slot 5. One end of the constant temperature plate 7 extends into the through groove 12 of the locking cylinder 9 and engages with the through groove 12.

[0037] It should be noted that the top of the telescopic rod 10 is fixedly connected to the inner top surface of the clamping cylinder 9, which facilitates the rotating shell 4 and the bottom of the telescopic rod 10 to rotate and connect.

[0038] In this embodiment, the constant temperature plate 7 is fan-shaped, corresponding to the culture area formed by the dish 1. When it is necessary to rotate the constant temperature plate 7 to the corresponding culture area, the rotating shell 4 is pulled out and pulled down, causing the lower part of the telescopic mechanism to extend and retract. The lower part of the telescopic rod 10 stretches the spring 11, and the constant temperature plate 7 disengages from the through groove 12 and rotates with the rotating shell 4. After the constant temperature plate 7 disengages from the through groove 12 and contacts the bottom surface of the retaining sleeve 9, the rotating shell 4 is rotated again until the constant temperature plate 7 is aligned with another through groove 12, at which point the spring 11 retracts. The lower part of the telescopic rod 10 is then pulled up, simultaneously pulling the rotating shell 4 upwards. This engages the constant temperature plate 7 within the through groove 12. The constant temperature plate 7 can provide constant temperature heating for the corresponding culture area in the dish 1.

[0039] Furthermore, a control switch 6 is provided on the bottom surface of the rotating shell 4. It is used to control the power supply to the battery pack 8.

[0040] Furthermore, after the thermostat plate 7 rotates, it corresponds to multiple areas on the bottom surface of the dish 1. This allows for multiple culture zones, enabling flexible heating and cultivation of the culture medium in each zone.

[0041] Preferably, the isolation plate 14 and the dish body 1, as well as the top plate 16 and the dish cover 2, are all integrally connected, wherein the bottom edge of the isolation plate 14 extends into the dish body 1 to insulate multiple culture zones.

[0042] In this embodiment, the airtightness is improved by integrating the isolation plate 14 with the dish body 1, the top plate 16 with the dish lid 2. At the same time, the bottom edge of the isolation plate 14 extends into the bottom wall of the dish body 1 to prevent the remaining culture area from being affected by temperature when the constant temperature plate 7 is heated.

[0043] Furthermore, the side of the dish lid 2 is provided with multiple micro-breathing holes 18. Air is introduced through the micro-breathing holes 18 to replace the carbon dioxide generated by the culture medium inside the dish body 1.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
