Description

Technical Field

[0001] This utility model relates to the field of microbial culture equipment technology, and in particular to a shaker for microbial culture with good mixing effect. Background Technology

[0002] A biological culture shaker is a commonly used laboratory instrument belonging to the category of biochemical instruments. It is widely used for bacterial culture, fermentation, hybridization, biochemical reactions, and enzyme and tissue research, where high temperature and oscillation frequency are required. Manual shaking primarily involves gentle horizontal shaking, which provides a stable culture environment for microorganisms, while appropriate rotational shaking accelerates the culture process.

[0003] Chinese utility model patent CN213012829U discloses a shaker for microbial experiments, including a mounting block with a mounting groove. A thermostat is fixedly mounted on the bottom inner wall of the mounting groove, and a motor is fixedly mounted on the bottom inner wall of the mounting groove. A first pulley is fixedly mounted on the output shaft of the motor. Two support columns are fixedly mounted on the bottom inner wall of the mounting groove, and the same second pulley is rotatably mounted on the two support columns. The first pulley and the second pulley are fitted with the same belt. Support arms are fixedly mounted on both sides of the second pulley, and tie rods are rotatably mounted on the support arms. Connecting blocks are movably mounted on the tie rods, and the same loading plate is fixedly mounted on the two connecting blocks.

[0004] This method utilizes a motor to drive a carrier plate to reciprocate within a certain range, thus achieving uniform mixing of the liquid inside the conical flask. However, the shaking direction is mostly concentrated in the longitudinal direction, and the shaking intensity is relatively strong, which can easily cause agitation of the culture medium inside the conical flask and disrupt the stability of the internal environment. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a shaker for microbial culture with good mixing effect, which solves the problem that the shaking of the culture medium in the existing shaker equipment is mainly concentrated in the vertical direction, resulting in excessive shaking amplitude and damage to the liquid environment.

[0006] The technical solution of this utility model is implemented as follows: a shaker for microbial culture with good mixing effect includes a tray for supporting triangular cell shake flasks. The tray is detachably mounted on a floating hanger. The floating hanger is connected to a horizontally arranged cross sliding mechanism. The cross sliding mechanism is located inside an incubator. The incubator is equipped with a driver, which is connected to a cam mechanism and connected to the floating hanger through the cam mechanism.

[0007] Preferably, the tray has several receiving slots, and the triangular cell shake flasks are placed in the receiving slots. Each receiving slot is threaded with a pressure ring for fixing the triangular cell shake flask. The inner ring surface of the pressure ring is provided with a foam pad that mates with the triangular cell shake flask.

[0008] Preferably, the floating support includes a cubic frame with symmetrical grooves on both sides, and the tray slides into the two grooves on both sides respectively. Further, the grooves have protrusions, and the tray has grooves that engage with the protrusions for secure locking.

[0009] Preferably, the cross sliding mechanism includes a first support fixedly connected to the cube frame, a pair of first optical axes parallel to each other on the first support, both first optical axes slidingly engaging with a cross slider, the cross slider slidingly engaging with a pair of second optical axes, both second optical axes fixedly mounted on a second support, and the second support fixedly connected to the top of the incubator. The first and second optical axes are arranged perpendicular to each other.

[0010] Preferably, the cam mechanism includes a cam fixedly mounted on the driver, a swing shaft vertically fixed on the cam's disk surface, a wheel seat at the bottom of the cubic frame, and a through hole on the wheel seat to allow the swing shaft to pass through.

[0011] Preferably, the driver is a servo motor. The incubator is equipped with a temperature-controlled heating element.

[0012] The beneficial effects of this invention are as follows: By setting up an incubator, a support base and a closed shaking environment are provided. The tray supports and fixes the triangular cell shakers, preventing instability during shaking. The floating hanger supports the tray and is detachably connected, facilitating the loading and unloading of the triangular cell shakers. A horizontally arranged cross-sliding mechanism supports the floating hanger, which, driven by a driver and cam mechanism, reciprocates horizontally, thus mixing the culture medium in the triangular cell shakers. This shaker has an appropriate shaking amplitude and a shaking method similar to manual shaking, with the shaking concentrated in the horizontal direction. This avoids excessive shaking due to amplitude or direction issues, which could damage the culture medium environment. The mixing effect is better, and the structure is highly reliable.

Detailed Implementation

[0021] 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.

[0022] like Figure 1 , 2As shown in Example 1, a shaker for microbial culture with good mixing effect includes a tray 2 for supporting triangular cell shake flasks 1. The tray supports and fixes the triangular cell shake flasks, preventing instability during shaking. The tray 2 is detachably mounted on a floating hanger 3, which supports the tray and is detachably connected for easy loading and unloading of the triangular cell shake flasks. The floating hanger 3 is connected to a horizontally arranged cross-sliding mechanism 4, which is located inside an incubator 5. The incubator provides a support base and a closed shaking environment for other components and triangular cell shake flasks. The incubator 5 is equipped with a driver 6, which is connected to a cam mechanism 7 and also connected to the floating hanger 3 through the cam mechanism 7. In this embodiment, the cross-sliding mechanism 4 is located at the top of the incubator, the driver is fixed at the bottom of the incubator, and the floating hanger is suspended and connected to the cross-sliding mechanism. With the support of the cross-sliding mechanism, it can move in multiple directions horizontally, and its bottom is driven by the cam mechanism located at the drive end of the driver.

[0023] In this embodiment, the tray is first removed from the floating rack, then several triangular cell shake flasks to be cultured and shaken are placed on the tray, and the tray is returned to the floating rack. The incubator is then turned off. When shaking is needed, the actuator is activated, which drives the cam mechanism. The moving end of the cam mechanism drives the floating rack, causing the entire floating rack to perform a continuous circular reciprocating motion in the horizontal direction under the support of the cross-sliding mechanism, thereby shaking the culture medium in the triangular cell shake flasks. In this embodiment, the shaking path for the triangular cell shake flasks is a horizontal circular path with appropriate shaking amplitude. The shaking method is similar to manual shaking, concentrating the shaking in the horizontal direction. This avoids excessive shaking due to shaking amplitude or direction issues, which could damage the culture medium environment. The shaking and mixing effect is better, and the structure has high reliability.

[0024] Example 2, based on Example 1, such as Figure 3 As shown, the tray 2 is provided with several receiving slots 21, and the triangular cell shake flask 1 is placed on the receiving slot 21. Each receiving slot 21 is threadedly connected to a pressure ring 22 for fixing the triangular cell shake flask 1. Furthermore, to improve the fit and fixation of the triangular cell shake flask, the inner ring surface of the pressure ring 22 is provided with a foam pad that mates with the triangular cell shake flask 1. Thus, when fixing the triangular cell shake flask, rotating the pressure ring causes the foam pad on the inner ring surface of the pressure ring to contact the outer wall of the triangular cell shake flask, achieving fixation. Simultaneously, the threaded connection allows for rapid disassembly and installation, improving efficiency. In this embodiment, the inner ring surface of the pressure ring is an inclined surface, fitting against the outer wall of the triangular cell shake flask, achieving better centering and fixation through a conical positioning method.

[0025] In this embodiment, the floating bracket 3 includes a cubic frame 31, with symmetrical grooves 32 on both sides of the cubic frame 31. The tray 2 slides into the two grooves 32 on both sides respectively. In actual use, when placing the tray, simply align the two sides of the tray with the grooves on both sides and push the tray into the cubic frame from the front.

[0026] To achieve locking of the pallet after it is pushed into the cubic frame, such as... Figure 6 As shown, in this embodiment, a protrusion 33 is provided on the slide groove 32, and a groove 23 is provided on the tray 2 to achieve a locking fit with the protrusion 33. During the pushing process, the protrusion is squeezed. When the protrusion is aligned with the tray groove, the two cooperate to lock the position of the tray.

[0027] As a further optional real-time method, an opening is provided circumferentially on the bottom side wall of the container 21 to observe the microorganisms cultured inside the triangular cell shake flask, while also facilitating temperature transfer.

[0028] Example 3, based on Example 2, such as Figure 4 As shown, the cross sliding mechanism 4 includes a first support 41 fixedly connected to the cube frame 31. A pair of first optical axes 42 are parallel to each other on the first support 41. Both first optical axes 42 are slidably engaged with a cross slider 43. The cross slider 43 is slidably engaged with a pair of second optical axes 44. The second optical axes 44 are fixedly mounted on a second support 45, which is fixedly connected to the top of the incubator 5. In this embodiment, the second support is a U-shaped support with its opening facing downwards. The two second optical axes are horizontally fixed at the opening of the second support. A support platform is provided at the top of the cube frame. The first support is fixed to the support platform, and the first optical axes are fixed to the first support.

[0029] In this embodiment, the axes of the first optical axis 42 and the second optical axis 44 are both located in two parallel horizontal planes. The first optical axis 42 and the second optical axis 44 are perpendicular to each other. Driven by the bottom cam mechanism, the floating hanger can move accordingly. When the floating hanger moves horizontally, the cross slider slides relative to the first optical axis and / or the second optical axis.

[0030] Example 4, based on Example 3, such as Figure 5As shown, the cam mechanism 7 includes a cam 71 fixedly mounted on the driver 6. A swing shaft 72 is vertically fixed on the surface of the cam 71. A wheel seat 73 is provided at the bottom of the cubic frame 31, and a through hole is provided on the wheel seat 73 to allow the swing shaft 72 to pass through. In this embodiment, the upper end of the swing shaft passes through the through hole and can rotate relative to the through hole. When the driver drives the cam to rotate, the swing shaft on the cam makes a horizontal circular motion, thereby driving the wheel seat above to move in a circular direction, achieving the purpose of shaking the triangular cell shaker located on the tray. By controlling the cam speed, the shaking speed can be controlled, and thus the shaking amplitude can be controlled.

[0031] In addition, in this embodiment, the driver 6 is a servo motor. The servo motor has good driving force and control precision, which is conducive to achieving precise control of the swaying amplitude and speed.

[0032] As a further optional implementation, a temperature-controlled heating element is provided inside the incubator 5. This heating element may include a heating wire and is electrically connected to the main control board. The main control board is also electrically connected to the driver, enabling control of the driver's rotation and speed during use. A temperature sensor is installed inside the incubator, providing real-time temperature feedback to the main control board. During actual use, a culture temperature command is set to the main control board. Once the target temperature is reached, the heating wire stops working. If the temperature sensor detects that the temperature is too low, the main control board controls the heating wire to reheat, maintaining the optimal culture temperature. Additionally, a door is provided on the front of the incubator for easy tray placement and removal. A light source is installed inside the incubator to meet the needs of different culture environments.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
