Description

Technical Field

[0001] This utility model belongs to the field of bacterial culture technology, specifically relating to a device for collecting volatile gases from bacterial cultures. Background Technology

[0002] Bacterial culture dishes are a common laboratory tool used for bacterial reproduction. During the cultivation of bacterial cultures, the corresponding fermentation broth needs to be added to the culture dish. During the fermentation process, some substances of the bacterial culture will volatilize at room temperature. The composition of the gases produced by this volatilization is unknown and can pollute the laboratory environment. Therefore, a professional gas collection device is needed to collect the volatilized gases.

[0003] Chinese invention patent CN103243022A discloses a simple device and method for collecting volatile gases from bacteria. The gas collection device includes an air pump, a sterile filter, a bacterial culture system, and a collection device. The air pump is connected to an air inlet pipe, and the air inlet pipe is connected to the bacterial culture system. A sterile filter for filtering volatile gases is installed inside the air inlet pipe. In use, the air pump is used to extract volatile gases. The volatile gases in the bacterial culture system are extracted together with the air. The volatile gases are filtered after passing through the sterile filter.

[0004] The gas collection device proposed in the aforementioned patent uses an air pump to draw volatile gases into the intake pipe, where they are then filtered by a sterile filter. This method stably filters volatile gases, reducing their contamination of the laboratory environment. However, during the experiment, researchers cannot accurately detect the various components within the volatile gases. These volatile gases are themselves part of the overall bacterial culture process. Simply filtering the volatile gases makes it impossible for researchers to determine the composition of the final bacterial culture product, thus affecting the effectiveness of the bacterial culture.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A device for collecting volatile gases from bacterial cultures includes a sealed chamber, a storage container, a drainage pipe, and a liquefaction chamber. The sealed chamber contains a storage container for the bacterial culture. A drainage pipe for outputting volatile gases is installed at the top opening of the sealed chamber.

[0009] As a preferred technical solution of this utility model, a baffle plate is installed at the side opening of the liquefaction tank, the baffle plate is in contact with the cover plate by pressing, and a sealing layer is installed on the surface of the extraction plate and below the baffle plate.

[0010] As a preferred technical solution of this utility model, the extraction component includes an outer shell, a vacuum pump, an output pipe and a connecting pipe. The outer shell is provided on the side of the liquefaction chamber, and the vacuum pump is installed inside the outer shell.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0030] Depend on Figure 1 As shown, this is a schematic diagram of the volatile gas collection device for bacterial culture in this embodiment. The gas collection device includes a sealed chamber 1, a storage container 2, a drainage pipe 3, and a liquefaction chamber 4. The sealed chamber 1 is provided with a storage container 2 for storing bacterial culture. A drainage pipe 3 for outputting volatile gas is installed at the top opening of the sealed chamber 1. The end of the drainage pipe 3 is connected to the liquefaction chamber 4. An extraction component 5 for extracting volatile gas is installed on the side of the liquefaction chamber 4.

[0031] In use, the culture dish containing bacterial culture is placed in the storage container 2, and then the sealing chamber 1 is closed to prevent external dust and impurities from falling into the culture dish. Then, by operating the extraction component 5, a negative pressure space is formed inside the drainage tube 3. The volatile gas generated in the sealing chamber 1 will enter the drainage tube 3 and be transported to the liquefaction chamber 4, completing the initial collection of volatile gas and reducing the impact of volatile gas on the laboratory environment.

[0032] From the appendix Figure 2As shown, this is a schematic diagram of the extraction component 5 in this embodiment. The extraction component 5 includes an outer shell 51, a vacuum pump 52, an output pipe 53, and a connecting pipe 54. The outer shell 51 is provided on the side of the liquefaction chamber 4. The vacuum pump 52 is installed inside the outer shell 51. The outlet of the vacuum pump 52 is connected to the output pipe 53, and the inlet of the vacuum pump 52 is connected to the connecting pipe 54. There are multiple sets of connecting pipes 54. The end of the connecting pipe 54 is connected to the liquefaction chamber 4, and the end of one set of connecting pipes 54 is connected to the inlet of the vacuum pump 52.

[0033] During use, connecting pipes 54 are laid according to the number of liquefaction chambers 4 set. Each group of liquefaction chambers 4 is connected by connecting pipes 54 to ensure that volatile gas flows stably from each group of liquefaction chambers 4 under the transportation of connecting pipes 54. By operating vacuum pump 52, the gas inside connecting pipes 54 and drainage pipes 3 is extracted, so that negative pressure space is formed in each group of pipelines, allowing the volatile gas in the sealed chamber 1 to enter the drainage pipe 3, thereby achieving stable transportation of volatile gas.

[0034] In this embodiment, a liquefaction mechanism 7 is installed in the liquefaction chamber 4 to promote the reliquefaction of volatile gases. The operation of the liquefaction mechanism 7 cools the volatile gases entering the liquefaction chamber 4, reduces the overall temperature of the volatile gases, and allows the volatile gases to generate heat, thereby driving the volatile gases to liquefy.

[0035] From the appendix Figure 6 As shown, it is a structural schematic diagram of the liquefaction mechanism 7 in this embodiment. The liquefaction mechanism 7 includes an extraction plate 71, a collection box 72, a shielding component 73, and a condenser component 74. The extraction plate 71 is slidably installed inside the liquefaction chamber 4. The collection box 72 is installed on the extraction plate 71. The shielding component 73 is installed at the top opening of the collection box 72. The condenser component 74 is installed on the side wall of the liquefaction chamber 4.

[0036] During use, the operation of the condenser assembly 74 reduces the overall temperature of the internal space of the liquefaction chamber 4. When volatile gas enters the liquefaction chamber 4, it releases its own heat, driving the volatile gas to liquefy. The liquefied material automatically enters the collection box 72 to complete the collection of volatile gas. Then, the operation of the vacuum pump 52 continues to extract the cooled gas, allowing the cooled gas to enter the next set of liquefaction chambers 4.

[0037] In this embodiment, multiple liquefaction chambers 4 are provided, each with a different temperature, to stably process various media in the volatile gas and collect the gas in batches according to the different temperatures.

[0038] From the appendix Figure 6 and Figure 7As shown, the shielding assembly 73 includes a cover plate 731, a rotating block 732, a rotating bracket 733, and a torsion spring 734. The rotating bracket 733 is installed on the side of the collection box 72, and the rotating block 732 is rotatably installed on the rotating bracket 733. The cover plate 731 is installed at the end of the rotating block 732. Torsion springs 734 are connected to both sides of the rotating block 732. The other end of the torsion spring 734 is connected to the side wall of the rotating bracket 733. A baffle plate is installed at the side opening of the liquefaction chamber 4. The baffle plate is in contact with the cover plate 731 by compression, and a sealing layer is installed on the surface of the extraction plate 71 below the baffle plate.

[0039] During use, after the collection box 72 has finished collecting the liquefied volatile gases, by pulling the extraction plate 71, the cover plate 731 is squeezed and pushed by the blocking plate. At this time, the overall angle of the cover plate 731 changes. As the extraction plate 71 continues to be pulled, the cover plate 731 rotates around the rotating bracket 733 as the axis, completing the sealing and blocking of the top opening of the collection box 72, preventing the material in the collection box 72 from being re-vaporized due to leaving the liquefaction chamber 4 and drifting out of the collection box 72.

[0040] When the cover plate 731 is rotated toward the opening of the collection box 72, the torsion spring 734 enters the storage state. When the collection box 72 is pushed back into the liquefaction chamber 4, the cover plate 731 will automatically reset itself, so that the liquefied volatile gas can enter the collection box 72.

[0041] From the appendix Figure 4 and Figure 5 As shown, this is a schematic diagram of the guiding mechanism 6 in this embodiment. The guiding mechanism 6 includes a rotating seat 61, a connecting end 62, a sealing cover 63, a fitting rubber ring 64, and a locking rod 65. An air inlet groove is provided on the side of the liquefaction chamber 4. The rotating seat 61 is installed on the side wall of the liquefaction chamber 4 directly above the air inlet groove. The connecting end 62 is rotatably installed on the side of the rotating seat 61. The sealing cover 63 is connected to the end of the connecting end 62. The fitting rubber ring 64 is installed on the side of the sealing cover 63. A fitting groove is provided on the inner wall of the liquefaction chamber 4 to fit with the fitting rubber ring 64. A locking rod 65 is installed on one side of the end of the rotating seat 61. The locking rod 65 limits the maximum swing distance of the sealing cover 63.

[0042] During use, the operation of vacuum pump 52 creates a negative pressure space between connecting pipe 54 and liquefaction chamber 4, causing the overall angle of sealing cover 63 to change. At this time, sealing cover 63 rotates around rotating seat 61 as the axis, and sealing cover 63 and adhesive ring 64 separate from the surface of adhesive groove, making it easier for volatile gas to enter liquefaction chamber 4 through air inlet groove. In addition, sealing cover 63 changes the flow trajectory of the new volatile gas, allowing the volatile gas to flow to one side of the bottom of liquefaction chamber 4, assisting in the liquefaction of volatile gas.

[0043] In this embodiment, the installation of the locking rod 65 controls the maximum swing distance of the sealing cover 63, so that after the vacuum pump 52 stops running, the sealing cover 63 deflects towards the side closer to the fitting groove under the action of gravity, thereby sealing and blocking the air inlet groove and achieving the sealing of the liquefaction chamber 4.

[0044] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
