Description

Technical Field

[0001] The present invention relates to the field of microbial culture, in particular to a culture bottle placement module and a microbial culture detection device. Background Art

[0002] Microbial culture and detection devices are widely used in medical diagnosis, food hygiene, scientific research experiments 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 detection devices have certain defects:

[0004] For example, the temperature regulation of existing microbial culture detection devices mainly relies on heating films and air cooling systems. For example, when the temperature needs to be increased, the PI heating film (polyimide heating film) is used to heat the plastic culture chamber, and then indirectly heat the culture bottle. Due to the low thermal conductivity of plastic, the temperature rise is slow, and due to the uneven heat conduction of the plastic cavity, the temperature difference between each hole can reach more than ±2°C. When the temperature needs to be lowered, a fan is used to drive air through the culture chamber, using air convection heat exchange. However, due to the limitations of the heat dissipation area and wind speed, the cooling rate is slow, and the system has difficulty in accurately controlling the heat exchange amount. Therefore, the time required for heating and cooling is relatively long, and the synchronization of microbial growth in the culture bottle cannot be guaranteed, making it difficult to meet the application requirements of rapid culture.

[0005] In addition, since the culture device uses plastic walls as the cavity material, its heat capacity is relatively low. Therefore, when the microbial culture detection device causes external air to rush into the culture chamber due to the opening and closing of the instrument door, the plastic walls will not be able to effectively buffer the temperature fluctuations due to insufficient heat capacity, that is, the temperature difference is large, which in turn leads to continuous instability in the culture environment. In addition, the above operation will also have a significant impact on the refrigeration operation of the biological culture detection device. For example, due to temperature reasons, the cooling is slow, which will cause significant differences in the growth rates of microorganisms in different culture bottles. Accordingly, the synchronization of microbial growth in the culture bottles cannot be guaranteed.

[0006] Therefore, a culture bottle placement module and a microorganism culture detection device are needed to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a culture bottle placement module and a microbial culture detection device to effectively improve the heating and cooling rates, and correspondingly improve the uniformity of heating of different culture bottles, and reduce the impact of the instrument door switch on the formation of culture bottles, thereby ensuring the synchronization of microbial growth in the culture bottles and meeting the needs of rapid culture and detection.

DETAILED DESCRIPTION

[0053] The following is a more detailed description of the culture bottle placement module and microbial culture detection device of the present invention, with reference to schematic diagrams. These schematic diagrams illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as generally known to those skilled in the art and is not intended to limit the present invention.

[0054] Moreover, based on the teachings of this specification, those skilled in the art may form new technical solutions by cross-combining different implementation methods without generating technical contradictions. Such variations should be deemed to fall within the scope of protection of this patent.

[0055] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are provided solely for the purpose of assisting in the description of the embodiments of the present invention.

[0056] Example 1

[0057] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a culture bottle placement module, comprising: a porous placement rack 7 for placing a culture bottle body 8, a frame plate, a heat sink, a first buckle plate 3 and a second buckle plate 6.

[0058] Among them, the frame plate has a hollow chamber, the porous placement rack 7 is fixedly installed in the hollow chamber, and the opening direction of the hollow chamber is parallel to the length direction of the placement hole set on the porous placement rack 7, so that it will not 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 material, and the high thermal conductivity of metal is used to increase the heating and cooling rates.

[0060] In this embodiment, mounting openings are provided on the upper and lower surfaces of the frame plate, and a semiconductor refrigerator (not shown in the figure) is built into the mounting opening and is in contact with the porous placement rack 7. The Peltier effect of the semiconductor refrigerator is utilized to directly cool the porous placement rack 7. The cold energy is quickly conducted to the culture bottle body 8 through the porous placement rack 7 made of metal, thereby achieving 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 semiconductor cooler, providing water-cooling and heat dissipation for the semiconductor cooler. This water-cooling system, formed by the heat sink and the semiconductor cooler, rapidly dissipates heat generated by the semiconductor cooler during operation, preventing cooling efficiency degradation due to temperature accumulation at the hot end. This ensures the semiconductor cooler's cooling effect on the porous rack 7 and provides assurance for precise temperature control.

[0062] The first buckle plate 3 and the second buckle plate 6 are respectively arranged on the two exposed sides of the porous placement rack 7, and are used to wrap the porous placement rack 7, that is, to cooperate with the frame plate to achieve all-round wrapping of the six sides of the porous placement rack 7, so as to 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 temperature uniform and stable environment for microbial culture.

[0063] It should be noted that the frame plate, the first gusset plate 3 and the second gusset plate 6 are all made of plastic. That is, by limiting the material of the frame plate, the first gusset plate 3 and the second gusset plate 6, the thermal insulation effect is further improved.

[0064] Among them, a heating film (not shown in the figure) for heating is sandwiched between the first buckle plate 3 and the second buckle plate 6 and the porous placement rack 7. The high thermal conductivity of the porous placement rack 7 made of metal material is utilized to enable the heat generated by the heating film to be quickly and evenly conducted to the culture bottle body 8, thereby improving the heating rate and effectively avoiding the occurrence of excessive temperature differences in each placement hole.

[0065] This device sets a porous placement rack 7 made of metal as a placement carrier for the culture bottle body 8 and clamps heating films on both sides thereof, so that the culture bottle body 8 can be quickly heated up through the heat conduction of the metal and the temperature difference in each placement hole can be effectively reduced. By setting a semiconductor refrigerator in contact with the porous placement rack 7 in the mounting holes on the upper and lower surfaces of the frame plate, the culture bottle body 8 can be quickly cooled down and the function of precise temperature control can be achieved with the help of water cooling of the heat sink and the thermal conductivity of the metal. In addition, a pair of porous placement racks 7 are formed in an all-round wrapping structure through the combination of the frame plate, the first buckle plate 3 and the second buckle plate 6, which can effectively reduce the influence 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 temperature uniform and stable environment for microbial culture, thereby achieving the purpose of ensuring the synchronization of microbial growth in the culture bottle body 8 and meeting the needs of rapid culture and detection.

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

[0067] It should be noted that the first clip plate 3 is detachable and can be replaced with a first clip plate 3 having light holes of different sizes according to needs, so that the light-through area can be dynamically adjusted according to the growth stage of the microorganisms, thereby avoiding signal saturation or missed detection problems caused by a fixed light-through 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-through hole is smaller than the outer diameter of the culture bottle body 8 to prevent the culture bottle body 8 from escaping from the light-through hole.

[0069] In this embodiment, a third gusset plate 4 is fixedly mounted on a side of the first gusset plate 3 away from the porous placement rack 7 .

[0070] The third gusset plate 4 is provided with a detection light board, and the light emitted by the detection light board is irradiated onto the culture bottle body 8 through the light hole, so as to detect the microorganisms in the culture bottle body 8 .

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

[0072] In a further embodiment, the frame plate is further limited to enhance the wrapping effect of the porous placement rack 7, so as to further reduce the impact of air convection generated 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 enclose to form the hollow chamber;

[0075] Among them, a shaft hole is provided on the first side plate 5 for fixed connection with the shaft, so that the subsequent rotation of the shaft 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 installation opening is provided on the second side plate 9 .

[0077] In other embodiments, a specific heat sink is provided to further enhance the water-cooling heat dissipation effect of the semiconductor cooler. Specifically, the heat sink includes a water-cooling plate 2 and a cover plate 1, which are arranged in a direction away from the frame plate. The water cooling circulation of the water-cooling plate 2 achieves the water-cooling heat dissipation function of the semiconductor cooler.

[0078] Specifically, the water-cooled plate 2 is provided with a fluid channel, which is connected to an external water circulation component. The cover plate 1 covers the fluid channel to circulate cooling water in the fluid channel to achieve the function of water cooling and heat dissipation.

[0079] Example 2

[0080] In the prior art, to accelerate the cultivation rate of microorganisms within the culture bottle body 8, the culture bottle placement module is typically controlled to reciprocate within a certain angle to promote the growth and metabolism of the microorganisms within the cell culture bottle body 8. For example, this enhances oxygen transfer and promotes uniform mixing of nutrients and metabolites, thereby achieving the purpose of accelerating the cultivation rate of the microorganisms within the culture bottle body 8. Therefore, in this embodiment, a specific driving member is proposed to better achieve the above functions.

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

[0082] The culture bottle placement module is arranged in the support frame, that is, the culture bottle placement module is supported by the support frame so that the culture bottle placement module can be driven to swing back and forth by the driving member.

[0083] In this embodiment, the driving member includes an eccentric disk 16, a connecting rod 17, a stepping motor 19, a sliding assembly, and a number of disks 11 and swing arms 13 that matches the number of the culture bottle placement modules.

[0084] The sliding assembly includes a linear guide rail and a sliding plate 18. The linear guide rail is arranged on the outer wall of the support frame, and the sliding plate 18 is installed 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 track.

[0085] The eccentric disk 16 is rotatably mounted on the outer wall of the support frame by 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 completing the control of 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 mounted on the edge of the outer surface of the disk 11 for connecting with a swing arm 13 to achieve swing control 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, and the rotating rod 12 is inserted into the U-shaped bayonet.

[0089] It should be noted that the opening direction of the U-shaped bayonet is horizontal, which is used to provide a movable margin for the rotating rod 12 in the horizontal direction, 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, in order to prevent the rotating rod 12 and the swing arm 13 from being separated, the support frame is further limited to improve the stability of the device operation.

[0091] Specifically, a first arc-shaped limit groove 211 is provided on the outer wall of the support frame, one end of the rotating rod 12 passes through the disc 11 and extends into the first arc-shaped limit groove 211, and the first arc-shaped limit groove 211 is used to limit the rotation range of the rotating rod 12 to prevent the rotating rod 12 from detaching 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, and the second arc-shaped limiting groove 212 is connected to the first arc-shaped limiting groove 211 through a linear limiting groove, so that the rotating shaft connected to the disc 11 culture bottle placement module and the rotating rod 12 can move along the linear limiting groove, and 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 part and is in a relatively static state, which is convenient for the operator to take or place the culture bottle body 8 in the culture bottle placement module.

[0093] It should be noted that there may be multiple groove structures formed by the first arc-shaped limiting groove 211, the second arc-shaped limiting groove 212 and the linear limiting groove, and the number thereof matches the number of the culture bottle placement modules.

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

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

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

[0097] The support plate 21 is fixedly mounted on the bottom plate 24 , and the plurality of culture bottle placement modules are rotatably mounted 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, and a gap is reserved between the partition 25 and the culture bottle placement module for the culture bottle placement module to swing, that is, the partition 25 is set to avoid the influence of temperature between the two culture bottle placement modules.

[0099] Wherein, a water circulation component is provided on the bottom plate 24, and the water circulation component is used to provide cooling water for the heat sink 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 to 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 bottom plate 24 to separate the culture bottle placement module from the water circulation assembly, thereby eliminating 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 the culture bottle placement modules is 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, and a gap is reserved between the partition 25 and the culture bottle placement module for the culture bottle placement module to swing.
