Description

Technical Field

[0001] This utility model relates to the field of microbial culture equipment technology, specifically a microbial oscillation culture device with stratified temperature control. Background Technology

[0002] Microbial culture refers to the process and method of promoting the growth and reproduction of microorganisms (such as bacteria, fungi, viruses, etc.) under artificially controlled environmental conditions, and microbial shaking incubators are commonly used equipment for aerobic culture in laboratories.

[0003] Traditional shaking incubators typically use a unified temperature control system to control the temperature of the entire internal space. However, in actual scientific research and production, it is often necessary to conduct multiple culture experiments under different temperature conditions simultaneously. The current main method is to use multiple independent shaking incubators, but this increases equipment costs, occupies a lot of laboratory space, and consumes a lot of energy. Therefore, a microbial shaking culture device with layered temperature control is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a microbial oscillation culture device with stratified temperature control to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a microbial oscillation culture device with layered temperature control, comprising a main chamber and multiple culture dishes, wherein multiple partition assemblies are horizontally arranged on the inner side of the main chamber, and the partition assemblies divide the interior of the main chamber into multiple independent culture chambers; The surface of the main housing is provided with an oscillation mechanism for driving multiple culture dishes to oscillate synchronously. The oscillation mechanism includes multiple swing frames, a rotating shaft, a crank, a rocker arm, a connecting bevel gear, and a transmission bevel gear. The culture dish is attached to the top of the swing frame via a snap-fit ​​structure. The vertical part of the crank is fixedly connected to the rotating shaft. The rocker arm is fixedly connected to the inclined part of the crank. The protrusion of the rocker arm is rotatably connected to the inner cavity of the swing frame. The connecting bevel gear and the transmission bevel gear in the meshing state are used to drive the crank and rocker arm to move via the rotating shaft.

[0006] Preferably, the partition assembly includes a heat-insulating partition, a clip, and a slot; The heat insulation partition is fixedly connected to the inner side of the main housing, the clip is fixedly connected to the surface of the heat insulation partition, and the slot is formed in the inner wall of the main housing.

[0007] Preferably, both the card and the card slot have a Z-shaped structure, and the card engages inside the card slot.

[0008] Preferably, the oscillation mechanism further includes a motor, a rotating rod, and a support; The motor is fixedly installed on the top of the main housing, the rotating rod is rotatably connected to the heat insulation partition, and the bracket is fixedly connected to the top of the heat insulation partition.

[0009] Preferably, the output shaft end of the motor is fixedly connected to the rotating rod, and the transmission bevel gear is fixedly assembled to the outer wall of the rotating rod.

[0010] Preferably, the swing frame is rotatably connected to the inner side of the support, and the rotating shaft is rotatably connected to one side of the support.

[0011] Preferably, the connecting bevel gear is fixedly assembled to the other end of the rotating shaft, and the connecting bevel gear meshes with the tooth groove of the transmission bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the partition assembly divides the interior of the main box into multiple vertically arranged independent culture chambers through the horizontal partition assembly. Each culture chamber 4 is an independent thermodynamic environment, which can be set and maintained at different temperatures. Thus, the user can set an independent culture temperature for each culture chamber according to the experimental requirements. This oscillation mechanism places a culture dish containing microbial culture medium into the corresponding culture chamber and fixes it on the oscillation frame. When the device is started, the independent temperature control system of each culture chamber starts working, quickly reaching and accurately maintaining its set temperature. At the same time, the motor located at the top of the chamber starts, driving all layers of the oscillation frame to oscillate synchronously and at the same frequency through the transmission system. This allows all culture dishes to undergo synchronous oscillation culture in their own independent temperature environment, thus solving the problem that traditional oscillation incubators cannot perform multi-temperature culture in the same device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides a technical solution for a microbial oscillation culture device with layered temperature control: a microbial oscillation culture device with layered temperature control includes a main box 1 and multiple culture dishes 2. Multiple partition components 3 are horizontally arranged on the inner side of the main box 1, and the partition components 3 divide the interior of the main box 1 into multiple independent culture chambers 4. The surface of the main housing 1 is provided with an oscillation mechanism 5 for driving multiple culture dishes 2 to oscillate synchronously. The oscillation mechanism 5 includes multiple swing frames 504, a rotating shaft 505, a crank 506, a rocker arm 507, a connecting bevel gear 508 and a transmission bevel gear 509. The petri dish 2 is mounted on the top of the swing frame 504 via a snap-fit ​​structure. The vertical part of the crank 506 is fixedly connected to the rotating shaft 505. The rocker arm 507 is fixedly connected to the inclined part of the crank 506. The protrusion part of the rocker arm 507 is rotatably connected to the inner cavity of the swing frame 504. The meshing bevel gear 508 and the transmission bevel gear 509 are used to drive the crank 506 and the rocker arm 507 to move via the rotating shaft 505.

[0017] Please refer to this carefully. Figure 2 The partition assembly 3 includes a heat-insulating partition 301, a clip 302, and a clip 303; The heat insulation partition 301 is fixedly connected to the inner side of the main housing 1, the clip 302 is fixedly connected to the surface of the heat insulation partition 301, and the slot 303 is formed in the inner wall of the main housing 1.

[0018] In this embodiment: the partition assembly 3 is the structural basis for forming the independent culture chamber 4. Its core is the heat insulation partition 301, which is made of a material with low thermal conductivity (such as high-density foam plastic, vacuum plate, etc.), which can effectively block the heat transfer between adjacent culture chambers 4 and prevent thermal short circuit.

[0019] Please refer to this carefully. Figure 3 Both the card 302 and the card slot 303 have a Z-shaped structure, and the card 302 is engaged inside the card slot 303.

[0020] In this embodiment: the heat insulation partition 301 is tightly connected to the inner wall of the main box 1 by the cooperation of the card 302 and the card slot 303. Both are designed as Z-shaped structures. This labyrinth structure not only provides a firm mechanical fixation, but also forms a tortuous physical path, which increases the thermal resistance of air convection, thereby strengthening the heat insulation and sealing effect between the culture chambers 4 in terms of structure.

[0021] Please refer to this carefully. Figure 4 The oscillation mechanism 5 also includes a motor 501, a rotating rod 502, and a support 503; The motor 501 is fixedly installed on the top of the main housing 1, the rotating rod 502 is rotatably connected to the heat insulation partition 301, and the bracket 503 is fixedly connected to the top of the heat insulation partition 301.

[0022] In this embodiment, all horizontal rotating shafts 505 are kept at the same speed and phase, which drives all cranks 506 and rockers 507 to work in the same way, ensuring that all culture dishes 2 placed on each layer of swing rack 504 can oscillate synchronously with the same frequency, amplitude and phase.

[0023] Please refer to this carefully. Figure 4 The output shaft end of the motor 501 is fixedly connected to the rotating rod 502, and the transmission bevel gear 509 is fixedly assembled on the outer wall of the rotating rod 502.

[0024] In this embodiment: Since the rotating rod 502 vertically penetrates all layers of heat insulation partition 301 and achieves rotational sealing through bearings and other structures, the sealing of each culture chamber 4 is ensured.

[0025] Please refer to this carefully. Figure 4 The swing frame 504 is rotatably connected to the inner side of the bracket 503, and the rotating shaft 505 is rotatably connected to one side of the bracket 503.

[0026] In this embodiment: when the crank 506 rotates, the protrusion at the end of the rocker arm 507 will move on an arc-shaped trajectory, and the swing frame 504 can swing back and forth at a small angle around the fulcrum of the support 503.

[0027] Please refer to this carefully. Figure 4 The connecting bevel gear 508 is fixedly mounted on the other end of the rotating shaft 505, and the connecting bevel gear 508 meshes with the tooth groove of the transmission bevel gear 509.

[0028] In this embodiment: when the rotating rod 502 drives the transmission bevel gear 509 to rotate, it converts the vertical rotational motion into the horizontal rotational motion through meshing with the connecting bevel gear 508, thereby driving the rotating shaft 505 to rotate in the horizontal plane.

[0029] Working principle: The interior of the main chamber 1 is divided into multiple vertically arranged independent culture chambers 4 by horizontal partition assembly 3. Each culture chamber is an independent thermodynamic environment that can be set and maintained at different temperatures. Each independent culture chamber 4 is equipped with a complete micro temperature control system. By starting the motor 501, its output shaft directly drives the rotating rod 502 to rotate. The rotating rod 502 then drives multiple transmission bevel gears 509 to rotate together. When the rotating rod 502 drives the transmission bevel gears 509 to rotate, through meshing with the connecting bevel gear 508, the vertical rotational motion is converted into horizontal rotational motion, thereby driving the rotating shaft 505 to rotate in the horizontal plane. The rotating shaft 505 then drives the crank 506 to rotate synchronously. When the crank 506 rotates, the protrusion at the end of the rocker arm 507 moves along an arc-shaped trajectory, allowing the swing frame 504 to reciprocate at a small angle around the fulcrum of the support 503. The internal design includes an inner cavity in which the protrusion of the rocker arm 507 is movably connected. When the protrusion of the rocker arm 507 makes a circular motion, it pushes the inner wall of the swing frame 504, thereby forcing the circular motion into the reciprocating swing of the swing frame 504 around its fulcrum. Since the connecting bevel gears 508 and transmission bevel gears 509 of all layers are driven by the same vertical rotating rod 502, all horizontal rotating shafts 505 maintain the same speed and phase, driving all crank rods 506 to work in a completely consistent manner with the rocker arm 507 structure, ensuring that all the culture dishes 2 placed on each layer of the swing frame 504 can oscillate synchronously with the same frequency, amplitude and phase. It should be noted that the temperature control system is a structure in existing devices. The independent temperature control system of each culture chamber 4 typically consists of the following four basic parts: a temperature sensor, usually a high-precision platinum resistance thermometer or thermistor, used to monitor the actual temperature inside the culture chamber 4 in real time and continuously, and convert the temperature signal into an electrical signal to feed back to the controller; a controller, usually a microprocessor (such as a PLC or a dedicated temperature control module), is an independent controller for each chamber, used to receive the target temperature set by the user for the culture chamber 4 and the actual temperature signal from the temperature sensor; an actuator (heating / cooling unit) is the component that directly changes the temperature, usually a small, high-efficiency resistance wire heater or film heater; a cooler, for cultures requiring temperatures below ambient, requires a semiconductor cooling chip, which can achieve both heating and cooling functions by changing the direction of the current; and a heat circulation and homogenization system, usually a small, low-noise fan, used to force airflow within the culture chamber 4, blowing it over the surface of the actuator (heating / cooling chip), and then blowing uniformly heated air throughout the entire chamber to ensure temperature uniformity within the chamber and avoid local overheating or undercooling points.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
