Description

Technical Field

[0001] This utility model relates to the field of microbial culture, and in particular to a culture bottle placement module and a microbial culture detection device. Background Technology

[0002] Microbial culture and detection devices are widely used in medical diagnosis, food hygiene, scientific research and other fields. Their core function is to provide a stable temperature environment for microbial growth and monitor the growth status in real time.

[0003] However, existing microbial culture and detection devices have certain shortcomings:

[0004] Existing microbial culture and detection devices primarily rely on heating films and air-cooling systems for temperature regulation. When heating is required, a PI (polyimide) heating film heats the plastic culture chamber, indirectly heating the culture flask. Due to the low thermal conductivity of plastic, heating is slow, and the uneven heat conduction within the plastic chamber results in temperature differences exceeding ±2°C between different wells. When cooling is needed, a fan drives airflow through the culture chamber for convection heat exchange. However, limited by the heat dissipation area and airflow velocity, the cooling rate is slow, and the system struggles to precisely control the heat exchange rate. Therefore, the heating and cooling processes are time-consuming, and the synchronicity of microbial growth within the culture flask cannot be guaranteed, making it difficult to meet the demands of rapid culture applications.

[0005] Furthermore, since the culture device uses plastic walls as the cavity material, its heat capacity is low. Therefore, when external air rushes into the culture chamber due to the opening and closing of the instrument door, the plastic walls cannot effectively buffer temperature fluctuations due to insufficient heat capacity, resulting in a large temperature difference. This leads to a continuously unstable culture environment. Moreover, the above operations will also significantly affect the cooling operation of the biological culture detection device, such as slow cooling due to temperature reasons. Consequently, there will be significant differences in the growth rate of microorganisms in different culture bottles, and the synchronicity of microbial growth in the culture bottles cannot be guaranteed.

[0006] Therefore, a culture bottle placement module and a microbial culture and detection device are needed to solve the above problems. Utility Model Content

[0010] The frame plate has mounting openings on both its upper and lower surfaces, and each mounting opening contains a semiconductor cooler that fits into the multi-hole placement rack.

[0011] The heat sink is fixedly installed on the surface of the frame plate and abuts against and fits against the semiconductor cooler for water cooling of the semiconductor cooler.

[0012] The first buckle plate and the second buckle plate are respectively disposed on the two exposed sides of the multi-hole placement rack, and a heating film for heating is sandwiched between them and the multi-hole placement rack.

[0013] Furthermore, the first buckle plate is provided with a plurality of light-transmitting holes corresponding to the culture bottle body, and the maximum inner diameter of the light-transmitting holes is smaller than the outer diameter of the culture bottle body;

[0017] Furthermore, the frame plate includes two symmetrically arranged first side plates and two symmetrically arranged second side plates;

[0024] On the other hand, this utility model also proposes a microbial culture and detection device, including: a support frame, at least one culture bottle placement module as described in the above embodiments, and a driving component;

[0025] The culture bottle placement module is arranged at equal intervals along the vertical direction within the support frame;

[0026] The driving components include an eccentric disk, a connecting rod, a stepper motor, a sliding assembly, and a disk and a swing arm that match the number of culture bottle placement modules.

[0027] The sliding assembly includes a linear guide rail and a sliding plate. The linear guide rail is disposed on the outer wall of the support frame, and the sliding plate is mounted on the linear guide rail.

[0028] The eccentric disk is rotatably mounted on the outer wall of the support frame via the stepper motor. One end of the connecting rod is hinged to the eccentric disk, and the other end is hinged to the sliding plate to form a crank-slider mechanism.

[0029] The disc is rotatably mounted on the outer wall of the support frame via a rotating shaft, and one end of the rotating shaft is fixedly connected to the corresponding culture bottle placement module;

[0032] The U-shaped bayonet has a horizontal opening, which provides a horizontal allowance for the rotating rod. When the sliding plate moves back and forth along the linear guide rail, the rotating rod drives the disc to rotate around the axis under the drive of the swing arm.

[0033] Furthermore, a first arc-shaped limiting groove is provided on the outer wall of the support frame. One end of the rotating rod passes through the disc and extends into the first arc-shaped limiting groove.

[0034] Furthermore, a second arc-shaped limiting groove is provided on the outer wall of the support frame, and the second arc-shaped limiting groove is connected to the first arc-shaped limiting groove through a straight limiting groove.

[0053] The culture bottle placement module and microbial culture detection device of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0054] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0055] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0056] Example 1

[0057] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a culture bottle placement module, including: a porous placement rack 7 for placing the culture bottle body 8, a frame plate, a heat sink, a first buckle plate 3, and a second buckle plate 6.

[0058] The frame plate has a hollow cavity, and the porous placement rack 7 is fixedly installed in the hollow cavity. The opening direction of the hollow cavity is parallel to the length direction of the placement hole provided on the porous placement rack 7, so as not to interfere with the placement of the culture bottle body 8.

[0059] It should be noted that the porous placement rack 7 is made of metal, which utilizes the high thermal conductivity of metal to improve the heating and cooling rates.

[0060] In this embodiment, the upper and lower surfaces of the frame plate are provided with mounting ports, and the mounting ports are equipped with semiconductor coolers (not shown in the figure) that fit into the porous placement rack 7. The Peltier effect of the semiconductor cooler is used to directly cool the porous placement rack 7. The cold energy is quickly conducted to the culture bottle body 8 through the metal porous placement rack 7, realizing rapid cooling and precise temperature control of the culture environment, thereby providing a stable low temperature environment for microbial culture.

[0061] Furthermore, the heat sink is fixedly mounted on the surface of the frame plate and abuts against the thermoelectric cooler for water-cooling the thermoelectric cooler. That is, the heat sink and the thermoelectric cooler form a water-cooling system, which can quickly remove the heat generated by the thermoelectric cooler during operation, preventing its cooling efficiency from decreasing due to heat accumulation at the hot end, ensuring the cooling effect of the thermoelectric cooler on the porous mounting rack 7, and providing assurance for precise temperature control.

[0062] The first buckle plate 3 and the second buckle plate 6 are respectively disposed on the exposed sides of the porous placement rack 7 to wrap the porous placement rack 7. That is, together with the frame plate, the porous placement rack 7 is fully wrapped on all six sides, which can effectively reduce the impact of air convection when the instrument door is opened and closed, thereby reducing the temperature fluctuation of the culture environment and realizing the function of providing a uniform and stable temperature environment for microbial culture.

[0063] It should be noted that the frame panel, the first snap-on plate 3, and the second snap-on plate 6 are all made of plastic. This limitation on the materials of the frame panel, the first snap-on plate 3, and the second snap-on plate 6 further enhances the insulation effect.

[0064] The first buckle plate 3 and the second buckle plate 6 are each sandwiched with a heating film (not shown in the figure) for heating between them and the porous placement rack 7. The porous placement rack 7 made of metal has high thermal conductivity, so that the heat generated by the heating film can be quickly and evenly conducted to the culture bottle body 8, which can improve the heating rate and effectively avoid the occurrence of excessive temperature difference in each placement hole.

[0065] This device uses a porous metal rack 7 as a carrier for the culture bottle body 8, with heating films sandwiched on both sides. The metal's thermal conductivity allows for rapid heating of the culture bottle body 8 while effectively reducing temperature differences within the placement holes. Furthermore, semiconductor coolers, fitted to the porous rack 7, are installed in mounting openings on the upper and lower surfaces of the frame plate. Utilizing water cooling and the thermal conductivity of the metal, the culture bottle body 8 can be rapidly cooled, achieving precise temperature control. The frame plate, the first snap-fit ​​plate 3, and the second snap-fit ​​plate 6 combine to form a structure that fully encloses the porous rack 7, effectively reducing the impact of air convection when the instrument door is opened and closed. This minimizes temperature fluctuations in the culture environment, providing a uniform and stable temperature environment for microbial culture. This ensures the synchronous growth of microorganisms within the culture bottle body 8, meeting the needs of rapid culture and detection.

[0066] In other embodiments, the first buckle plate 3 is provided with a plurality of light-transmitting holes corresponding to the culture bottle body 8.

[0067] It should be noted that the first buckle plate 3 is detachable, and it can be replaced with a first buckle plate 3 with different sizes of light-transmitting holes as needed. This allows for dynamic adjustment of the light-transmitting area according to the microbial growth stage, avoiding signal saturation or missed detection problems caused by a fixed light-transmitting area, thereby improving the accuracy and adaptability of detection signal acquisition.

[0068] It should also be noted that the maximum inner diameter of the light-transmitting hole is smaller than the outer diameter of the culture bottle body 8, to prevent the culture bottle body 8 from detaching from the light-transmitting hole.

[0069] In this embodiment, a third buckle plate 4 is also fixedly installed on the side of the first buckle plate 3 away from the perforated mounting bracket 7.

[0070] The third buckle plate 4 is equipped with a detection lamp plate. The light emitted by the detection lamp plate shines through the light-transmitting hole onto the culture bottle body 8, which is used to detect microorganisms in the culture bottle body 8.

[0071] The second buckle plate 6 is provided with a through hole for exposing the mouth end of the culture bottle body 8.

[0072] In a further embodiment, the frame plate is further defined to improve the wrapping effect on the porous placement rack 7, thereby further reducing the impact of air convection when the instrument door is opened and closed.

[0073] Specifically, the frame plate includes two symmetrically arranged first side plates 5 and two symmetrically arranged second side plates 9.

[0074] The two first side plates 5 and the two second side plates 9 are fixedly connected to the outer surface of the porous placement rack 7, and together they form the hollow cavity.

[0075] The first side plate 5 is provided with a pivot hole for fixed connection with a pivot, so that the rotation of the pivot can drive the porous placement rack 7 to swing back and forth, so that the heating position of the microorganisms in the culture bottle body 8 can be continuously changed, thereby further improving the uniformity of heating of the microorganisms in the culture bottle body 8.

[0076] In this embodiment, the mounting port is located on the second side plate 9.

[0077] In other embodiments, a specific heat dissipation component is proposed to better improve the water-cooling effect on the thermoelectric cooler. Specifically, the heat dissipation component includes a water-cooling plate 2 and a cover plate 1 arranged sequentially from the direction away from the frame plate, and the water-cooling circulation of the water-cooling plate 2 realizes the water-cooling function of the thermoelectric cooler.

[0078] Specifically, the water-cooled plate 2 has fluid channels arranged on it, which are connected to an external water circulation component. The cover plate 1 covers the fluid channels to achieve water cooling and heat dissipation through the circulation of cooling water within the fluid channels.

[0079] Example 2

[0080] In existing technologies, to accelerate the cultivation rate of microorganisms within the culture flask body 8, the culture flask placement module is typically controlled to reciprocate within a certain angle to promote the growth and metabolism of microorganisms within the cell culture flask body 8, such as enhancing oxygen transfer and promoting the uniform mixing of nutrients and metabolites, thereby achieving the goal of accelerating the cultivation rate of microorganisms within the culture flask body 8. Therefore, in this embodiment, a specific driving component is proposed to better achieve the above functions.

[0081] like Figures 3 to 5 As shown, this embodiment proposes a microbial culture and detection device based on embodiment one, including: a support frame, at least one culture bottle placement module as described in embodiment one, and a driving component.

[0082] The culture bottle placement module is located inside the support frame, that is, the support frame supports the culture bottle placement module so that the drive component can drive the culture bottle placement module to swing back and forth.

[0083] In this embodiment, the driving component includes an eccentric disk 16, a connecting rod 17, a stepper motor 19, a sliding assembly, and a disk 11 and a swing arm 13 that match the number of culture bottle placement modules.

[0084] The sliding assembly includes a linear guide rail and a sliding plate 18. The linear guide rail is disposed on the outer wall of the support frame, and the sliding plate 18 is mounted on the linear guide rail. That is, by setting the linear guide rail, the sliding plate 18 is limited so that the sliding plate 18 can only move along a predetermined trajectory.

[0085] The eccentric disk 16 is rotatably mounted on the outer wall of the support frame via the stepper motor 19. One end of the connecting rod 17 is hinged to the eccentric disk 16, and the other end is hinged to the sliding plate 18 to form a crank-slider mechanism for controlling the reciprocating movement of the sliding plate 18.

[0086] The disc 11 is rotatably mounted on the outer wall of the support frame via a rotating shaft, and one end of the rotating shaft is fixedly connected to the corresponding culture bottle placement module, so that the disc 11 and the culture bottle placement module are connected as a whole. Therefore, the reciprocating swing of the culture bottle placement module can be achieved by controlling the reciprocating swing of the disc 11.

[0087] In this embodiment, a rotating rod 12 is fixedly installed at the edge of the outer surface of the disk 11 for connecting with the swing arm 13 to control the swing of the disk 11.

[0088] One end of the swing arm 13 is fixedly connected to the sliding plate 18, and the other end is provided with a U-shaped bayonet, into which the rotating rod 12 is inserted.

[0089] It should be noted that the opening direction of the U-shaped bayonet is horizontal, which is used to provide a horizontal range of motion for the rotating rod 12, so that when the sliding plate 18 moves back and forth along the linear guide rail, the rotating rod 12 drives the disc 11 to rotate around the rotating axis under the drive of the swing arm 13.

[0090] like Figure 6 As shown, in other embodiments, to prevent the rotating rod 12 from detaching from the swing arm 13, the support frame is further defined to improve the stability of the device operation.

[0091] Specifically, a first arc-shaped limiting groove 211 is provided on the outer wall of the support frame. One end of the rotating rod 12 passes through the disk 11 and extends into the first arc-shaped limiting groove 211. The first arc-shaped limiting groove 211 is used to limit the rotation range of the rotating rod 12 to prevent the rotating rod 12 from disengaging from the end of the swing arm 13.

[0092] In addition, a second arc-shaped limiting groove 212 is provided on the outer wall of the support frame. The second arc-shaped limiting groove 212 is connected to the first arc-shaped limiting groove 211 through a straight limiting groove, so that the rotating shaft and rotating rod 12 connected to the culture bottle placement module of the disc 11 can move along the straight limiting groove. When the rotating rod 12 can rotate around the rotating shaft and enter the second arc-shaped limiting groove 212, the culture bottle placement module is separated from the driving component and is in a relatively static state, which makes it convenient for the operator to pick up or place the culture bottle body 8 in the culture bottle placement module.

[0093] It should be noted that multiple groove structures can be formed by connecting the first arc-shaped limiting groove 211, the second arc-shaped limiting groove 212, and the straight limiting groove, and the number of such structures can match the number of culture bottle placement modules.

[0094] In other embodiments, the outer surface of the eccentric disk 16 is provided with a baffle 15, and the outer wall of the support frame is provided with a photoelectric sensor 14 for sensing and detecting the baffle 15, so that the operator can obtain the position information of the culture bottle placement module and judge the overall operating status of the device.

[0095] In a further embodiment, a specific support frame is also proposed to further reduce the impact on the temperature of the culture flask placement module.

[0096] Specifically, the support frame includes a base plate 24, two symmetrically arranged support plates 21, and a baffle 20.

[0097] The support plate 21 is fixedly installed on the base plate 24, and the multiple culture bottle placement modules are rotatably installed between the two support plates 21.

[0098] The partition 25 is fixedly connected to the two support plates 21 and is used to separate two adjacent culture bottle placement modules in the vertical direction. A gap is reserved between the partition 25 and the culture bottle placement module for the culture bottle placement module to swing. That is, by setting the partition 25, the temperature influence between the two culture bottle placement modules is avoided.

[0099] The base plate 24 is provided with a water circulation component, which is used to provide cooling water for the heat dissipation components of the culture bottle placement module.

[0100] Specifically, the water circulation assembly includes a water pump 22 connected to the input end of the heat sink and a water drain 23 connected between the water pump 22 and the output end of the heat sink. This is prior art and will not be described in detail here.

[0101] The baffle 20 is fixedly connected to the two support plates 21 and the base plate 24, serving to separate the culture bottle placement module and the water circulation assembly. This eliminates the temperature impact of the heat generated by the water circulation assembly during operation on the culture environment of the culture bottle placement module.

[0102] In other embodiments, the number of culture bottle placement modules is set to multiple, and the multiple culture bottle placement modules are equidistantly arranged in the support frame along the vertical direction;

[0103] The support frame also includes a partition 25, which is fixedly connected to the two support plates 21 and is used to separate two adjacent culture bottle placement modules in the vertical direction. A gap is reserved between the partition 25 and the culture bottle placement module for the culture bottle placement module to swing.

[0104] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
