[0057] The following describes in detail the laboratory microbiology observation box according to an embodiment of the present invention with reference to the accompanying drawings.

[0058] Reference Figures 1 to 6 As shown, the laboratory microbiology observation box provided according to an embodiment of the present invention includes a closed box 10, an entry and exit mechanism 20 and an adjustable lamp 30.

[0059] Specifically, the enclosed box 10 comprises an enclosed chamber with an opening H102 for loading a sample and a transparent observation window H101 for the experimenter to observe the sample within. In this embodiment, the enclosed box 10 is made of stainless steel, which offers excellent corrosion resistance and easy cleaning. The transparent observation window H101 is constructed of highly transmittance tempered glass, ensuring clear observation and adequate safety.

[0060] The access mechanism 20 includes a pallet 201 and a drive mechanism 202 that controls the pallet 201's entry and exit from the closed chamber through the chamber opening H102. The pallet 201 is made of a high-temperature, corrosion-resistant plastic material and features positioning grooves on its surface for culture dishes, ensuring stable placement of samples. The drive mechanism 202 utilizes a rack and pinion drive mechanism, a belt drive mechanism, a screw drive mechanism, or other mechanisms to ensure smooth entry and exit of the pallet 201.

[0061] The adjustable lamp 30 is located at the top of the enclosure 10 and is configured to allow the user to adjust the direction of its light projection so that the light is projected onto the sample area. The user can adjust the position and angle of the adjustable lamp 30 by rotating it, thereby adjusting the direction of light projection and ensuring that the light is precisely projected onto the sample area. Preferably, the adjustable lamp 30 utilizes high-color rendering LEDs with a color temperature adjustable between 3000K and 6500K to accommodate the observation needs of different samples.

[0062] In actual use, the experimenter first places the petri dish containing the microbial sample on the support plate 201. Then, by controlling the access mechanism 20, the sample is transported into the enclosed chamber. Next, the position and angle of the adjustable lamp 30 are adjusted so that its light is projected directly onto the sample area, creating optimal observation conditions. Through the transparent observation window H101, the experimenter can clearly observe the colony characteristics of the sample without worrying about interference from the external environment. Once the observation is complete, the access mechanism 20 is activated again to remove the sample.

[0063] According to the laboratory microbiology observation box provided by the embodiment of the present invention, the closed box 10 provides an independent observation environment, effectively isolating external light and other interference factors, and ensuring the stability of the observation environment. The entry and exit mechanism 20 makes the placement and removal of samples more convenient, reducing the interference that may be caused to the samples during operation. In addition, the setting of the adjustable lamp 30 allows the experimenter to adjust the projection direction of the light as needed. The experimenter can observe the various characteristics of the colony more clearly, including size, shape, edge, surface properties, protrusion, color and transparency, etc., which significantly improves the accuracy and reliability of observation and increases the efficiency of the experimental process.

[0064] In one embodiment of the present invention, a through hole is provided on the top wall of the closed box 10. A flexible sleeve 103 is provided in the through hole. The flexible sleeve 103 is made of a highly elastic and wear-resistant silicone material.

[0065] The adjustable lamp 30 is housed within the flexible sleeve 103 and can freely deflect and swing to adjust the direction of its light projection. For example, the adjustable lamp 30 includes a lamp body 301 and a lamp handle 302. The lamp body 301 houses an LED light source with a power of 10 to 60W and an adjustable color temperature between 3000K and 6500K. The lamp handle 302 is convenient for the user to grip and operate, allowing for adjustment of the light projection angle. The material can be made of high-strength plastic or aluminum alloy, making it both lightweight and durable.

[0066] Due to the design of the flexible sleeve 103, the adjustable lamp 30 can freely deflect and swing within the flexible sleeve 103. For example, the adjustable lamp 30 can rotate 360 ​​degrees in the horizontal plane and deflect ±45 degrees in the vertical direction. This design allows the user to precisely adjust the projection direction of light to suit different observation positions and sample requirements.

[0067] During actual use, when the light direction needs to be adjusted, the user simply needs to gently grasp the lamp handle 302 and rotate it to easily change the angle of the adjustable lamp 30. The flexible sleeve 103 deforms as the adjustable lamp 30 rotates, and after releasing the lamp handle 302, the adjustable lamp 30 returns to its original state. This design not only improves the flexibility and precision of light adjustment, but also ensures the sealing of the closed chamber. Compared with traditional fixed lighting, this adjustable design can better adapt to the observation needs of microbial samples of different types and sizes, significantly improving the effect and efficiency of observation.

[0068] In one embodiment of the present invention, the flexible sleeve 103 is formed into a conical structure with a diameter gradually decreasing from top to bottom. The adjustable lamp 30 is a cylindrical piece, and the lower end of the adjustable lamp 30 is sleeved on the lower end of the flexible sleeve 103, and the upper end of the adjustable lamp 30 extends from the upper end of the flexible sleeve 103 for user operation.

[0069] In this embodiment, the flexible sleeve 103 adopts a conical structure. This conical design not only increases the deformation space of the flexible sleeve 103, thereby improving the angle adjustment range of the adjustable lamp 30, but also provides appropriate resistance when adjusting the adjustable lamp 30, ensuring the stability of the adjustment. The lower end of the adjustable lamp 30 is sleeved on the lower end of the flexible sleeve 103. This design allows the light source part of the adjustable lamp 30 to be located in the closed chamber and can directly illuminate the sample. The upper end of the adjustable lamp 30 extends from the upper end of the flexible sleeve 103, that is, the lamp handle 302 extends from the upper end of the flexible sleeve 103, and the user can adjust the lamp by holding the lamp handle 302.

[0070] Preferably, the flexible sleeve 103 is a compressible structure formed by connecting multiple levels of folds 1031 in sequence along the vertical direction. This compression design greatly improves the flexibility and adaptability of the flexible sleeve 103 and provides a wider range of freedom for adjusting the adjustable lamp 30.

[0071] For example, the cross-section of the pleated portion 1031 is V-shaped with an angle of 60°. This design not only increases the compression of the pleated portion 1031 but also provides uniform force distribution during compression and extension, thus avoiding stress concentration and extending the service life of the flexible sleeve 103.

[0072] In one embodiment of the present invention, the upper end of the flexible sleeve 103 has a lip protruding radially outward, and the lip is pressed and fixed to the outer surface of the top wall of the closed box 10 by a fixed pressure ring 104. For example, the fixed pressure ring 104 can be fixed to the sealed box by screws. By using the fixed pressure ring 104 to press the lip of the upper end of the flexible sleeve 103 to the top wall of the closed box 10, the flexible sleeve 103 can be installed, and a reliable sealing state is ensured between the flexible sleeve 103 and the closed box 10, thereby preventing external ambient light from entering the closed box 10 and interfering with its internal environment, thereby improving reliability.

[0073] In some embodiments of the present invention, the compartment opening H102 is located on the front wall of the closed box 10. The drive mechanism 202 includes a bracket 2021, a screw, a guide rod 2022, a movable base 2023, and a drive motor 2024. The bracket 2021 is fixedly disposed within the closed compartment, and the screw is pivotally mounted on the bracket 2021. The guide rod 2022 is clamped onto the bracket 2021 and is parallel to and adjacent to the screw. The provision of the guide rod 2022 prevents the movable base 2023 from rotating during movement, thereby ensuring smooth movement of the support plate 201.

[0074] The movable seat 2023 is slidably mounted on the guide rod 2022 and has a threaded hole that engages with the threaded screw. Rotation of the screw drives the movable seat 2023 along the screw. The support plate 201 is relatively fixed to the movable seat 2023 and can be fixedly connected to the movable seat 2023 via bolts. A drive motor 2024 is connected to the screw to drive the screw to rotate, thereby moving the movable seat 2023 along the screw's axis.

[0075] When pallet 201 needs to be moved into the closed chamber, the control system first sends a forward rotation signal to drive motor 2024. Drive motor 2024 begins to rotate, transmitting the rotational motion to the screw through the coupling. The screw begins to rotate clockwise. Because the threaded hole in the movable base 2023 mates with the screw thread, and the movable base 2023 is restricted in rotation by guide rod 2022, the rotational motion of the screw is converted into linear motion of the movable base 2023. The movable base 2023 drives the pallet 201, to which it is fixed, into the closed chamber.

[0076] When the pallet 201 needs to exit the closed chamber, the control system sends a reverse rotation signal to the drive motor 2024. The drive motor 2024 begins to rotate in the reverse direction, driving the screw rod to rotate counterclockwise. At this time, the movable seat 2023, driven by the screw rod, moves toward the chamber opening H102, thereby allowing the pallet 201 to exit the closed chamber.

[0077] In the whole process, the guide rod 2022 plays a vital role. It not only prevents the moving seat 2023 from rotating and ensures that the moving seat 2023 can only move along the axial direction, but also shares part of the load, reduces the wear of the screw rod, and improves the stability and service life of the entire mechanism.

[0078] The driving mechanism 202 of this embodiment converts rotational motion into linear motion, and combined with the transmission accuracy of the screw rod, achieves high-precision and smooth movement of the support plate 201, thereby improving the convenience and reliability of use.

[0079] In one embodiment of the present invention, the enclosed box 10 includes a base box 101 and a front shell 102. The front shell 102 is detachably fixed to the base box 101, and the connection between the front shell 102 and the base box 101 can be achieved by means of a snap-on connection, screw connection, or the like. Beveled surfaces S101 are formed on the left and right sides of the front shell 102, and each of the beveled surfaces S101 is mounted with an ambient light strip 105. The ambient light strip 105 extends in a front-to-back direction and provides basic lighting within the enclosed compartment.

[0080] In this embodiment, ambient light is provided by setting an ambient light strip. The ambient light takes into account the needs of microbial observation and provides a soft and uniform basic lighting environment. Combined with the directional lighting of the adjustable lamp 30, the observation effect can be significantly improved.

[0081] For example, the angle between the beveled surface S101 and the horizontal plane can be designed to be 45 degrees. This angle can evenly distribute light within the enclosed chamber. The ambient light strip 105 can be an LED light strip with a color temperature of 4000K-5000K, providing a lighting effect close to natural light. To achieve a better lighting effect, a dimming function can be configured in the control circuit. For example, 10 levels of brightness adjustment can be set, allowing users to adjust the lighting intensity according to the needs of different samples.

[0082] Preferably, the front side of the face shell 102 forms a downwardly inclined observation surface, and the transparent observation window H101 is provided on the observation surface. Preferably, the angle between the observation surface and the horizontal plane is 45°. In this way, the inclined observation surface can provide a more comprehensive and clearer observation angle, allowing the experimenter to observe the sample more comprehensively and accurately.

[0083] In one embodiment of the present invention, the lower end of the flexible sleeve 103 has a radially inwardly protruding stop edge, and the lower end of the adjustable lamp 30 has a radially outwardly protruding stop ring 301a, which can stop above the stop edge.

[0084] When assembling the adjustable lamp 30 and the flexible sleeve 103, the lower end of the adjustable lamp 30 is simply inserted into the flexible sleeve 103 until the retaining ring 301a contacts the stop edge at the lower end of the flexible sleeve 103. This design makes assembly and disassembly between the adjustable lamp 30 and the flexible sleeve 103 more convenient and easier, facilitating maintenance and cleaning of the adjustable lamp 30.

[0085] In one embodiment of the present invention, a control panel is provided on the closed box 10 , and the control panel has a door control button for controlling the in-and-out mechanism 20 , and a light source control button for controlling the ambient light strip 105 .

[0086] During use, the experimenter first activates the ambient light strip 105 using the light source control button. This provides internal ambient light, ensuring visibility inside the closed chamber. The operator then uses the door control button to control the entry and exit mechanism 20 to exit the chamber, place the sample, and transport it into the closed chamber. Finally, the adjustable lamp 30 illuminates the sample for observation.

[0087] The use of the control panel improves the convenience of user operation, allowing experimenters to focus more on microbial observation itself, thereby improving work efficiency and experimental accuracy.
