Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a shaker device. Background Technology

[0002] Shaking flask apparatuses are common laboratory devices used for microbial culture, chemical reactions, and textile processing. They use a drive system to oscillate the flasks to mix liquids. Existing apparatuses mainly consist of a shaking platform, a fixing structure, and a drive system. The fixing structure often uses spring clips or slot designs; however, spring clips require manual adjustment, which is cumbersome and inefficient, while slot designs only fit bottles of a specific size, lacking versatility. Furthermore, to increase capacity, some apparatuses use multi-layer shaking platforms, but this requires operation layer by layer and results in insufficient space utilization. For example, multi-layer structures are difficult to stack compactly due to fixing limitations, leading to wasted effective oscillation area. Existing drive systems often directly drive a single-layer platform, and stacked structures lack a synchronous and stable oscillation scheme, easily causing bottle displacement. Utility Model Content

[0003] In view of the above problems, the present invention aims to provide a shaking bottle device to solve the problems of inconvenient operation and low space utilization of existing devices.

[0004] To achieve the above objectives, this application provides a shaker device, including a shaker housing, a support plate, and a drive unit. The shaker housing has a storage slot for holding shakers. A fixing component is provided along the upper edge of the shaker housing to fix the stacked shaker housings. The support plate includes a telescopic limiting pin and a spring. Multiple limiting holes are arrayed on the support plate, each fitting the telescopic limiting pin. The spring is placed within the limiting holes, with both ends abutting against the telescopic limiting pin and the bottom of the limiting hole, respectively. The shaker housings are stacked on the support plate. The drive unit includes a cam, a drive rod, and a drive motor. The output end of the drive motor is connected to the cam, which drives the cam to rotate. The cam has a sliding groove, and the drive rod moves along the sliding groove. The other end of the drive rod is connected to the support plate.

[0005] Unlike existing technologies, the above-mentioned solution achieves efficient parallel processing of multiple samples through the stacked design of the shake flask chamber and the array of limiting holes in the support plate, significantly improving space utilization. The telescopic limiting pins selectively retract or extend when the shake flask chambers are stacked, avoiding vertical pressure interference and limiting horizontal displacement through elastic contact, ensuring the stability of the chamber during oscillation. The non-circular sliding groove track of the cam causes the support plate to reciprocate, simulating the variable speed characteristics of artificial oscillation, enhancing the liquid turbulence effect, and meeting the deep wetting requirements of the sample and liquid. The cooperation between the drive rod and the cam converts the rotational motion into a controllable oscillation, causing the stacked chambers to oscillate synchronously, ensuring the uniformity of sample processing in each layer. This device only requires placing the shake flask chamber and starting the drive motor during operation, eliminating the need for layer-by-layer adjustment of the fixed structure, improving ease of use, and adapting to different flask sizes while simplifying the operation process, meeting the high-efficiency requirements of multi-sample, multi-batch processing.

[0006] In some embodiments, the fixing component includes a first torsion spring, a supporting section and a fixing section, the supporting section and the fixing section are connected to each other and perpendicular to each other, the upper edge of the shaker body is rotatably connected to the fixing component, one end of the first torsion spring is connected to the fixing component, and the other end of the first torsion spring is connected to the side wall of the shaker body, and the fixing component is used to limit the position of the shaker body.

[0007] In some embodiments, a hook is provided at the end of the fixed section away from the supporting section, and a slot is provided at the relative position of the shaker box, with the hook and slot being adapted to fix the other shaker box above.

[0008] In some embodiments, the lower edge of the card slot is chamfered.

[0009] In some embodiments, there are multiple storage slots, and the upper edge of the storage slot is provided with an L-shaped retaining plate and a second torsion spring. The L-shaped retaining plate is rotatably connected to the storage slot, one end of the second torsion spring is connected to the L-shaped retaining plate, and the other end of the second torsion spring is connected to the inner wall of the storage slot. The L-shaped retaining plate is used to fix the shaker.

[0010] In some embodiments, a cushioning pad is provided at the bottom of the storage compartment.

[0011] In some embodiments, the drive motor is a variable frequency speed control motor.

[0012] In some embodiments, a transparent observation window is provided on the side of the shaking flask chamber for observing the shaking flask.

[0013] Unlike existing technologies, this invention provides a shaker device that achieves efficient, stable, and highly adaptable sample processing through an integrated stacked structure, dynamic limiting, and variable speed drive system. The stacked design of the shaker housing, combined with the array of limiting holes on the support plate and the elastic contraction and extension characteristics of the telescopic limiting pins, enables parallel processing of multiple samples and efficient space utilization. Selective limiting avoids vertical pressure interference and restricts horizontal displacement, ensuring the oscillation stability of the stacked housing. The non-circular sliding groove track of the cam drives the support plate to generate variable speed reciprocating motion, simulating the variable speed characteristics of artificial oscillation, enhancing the liquid turbulence effect, and meeting the deep wetting requirements of the sample and liquid. The L-shaped fixing component, through the elastic reset of the first torsion spring and the mechanical locking of the hook and slot, achieves rapid alignment and stable fixation during stacking. The chamfered structure optimizes the hook separation path, improving loading and unloading efficiency. The L-shaped clamping plate of the storage slot works in conjunction with the second torsion spring to adaptively clamp shakers of different sizes. Combined with the elastic cushioning and friction limiting of the bottom buffer pad, it ensures both shaker protection and reliable fixation. The variable frequency speed-regulating motor meets diverse oscillation intensity requirements through wide-range precise speed regulation. Its smooth start-stop characteristics reduce mechanical shock. Combined with the real-time monitoring function of the transparent observation window, it achieves comprehensive optimization of operation convenience, equipment durability, and energy economy while ensuring visualization and sealing of the experimental process. This device, through the coordinated design of mechanical limits, elastic adaptation, and motion control, effectively solves the problems of low sample processing efficiency, poor fixation stability, cumbersome operation, and insufficient versatility of traditional equipment. It is suitable for diverse sample processing needs in fields such as biopharmaceuticals, chemical synthesis, and textile processing.

[0048] Please see Figures 1 to 7 This embodiment provides a shaker device, including a shaker box 1, a support plate 2, and a drive unit 3. The shaker box 1 is provided with a storage slot 11 for placing shakers 12. A fixing component 13 is provided on the upper edge of the shaker box 1 to fix the stacked shaker boxes 1. The support plate 2 includes a telescopic limiting pin 21 and a spring 22. Multiple limiting holes are arranged in an array on the support plate 2. The limiting holes are adapted to the telescopic limiting pin 21. The spring 22 is placed in the limiting hole, and both ends of the spring 22 abut against the telescopic limiting pin 21 and the bottom of the limiting hole, respectively. The shaker boxes 1 are stacked on the support plate 2. The drive unit 3 includes a cam 31, a drive rod 32, and a drive motor. The output end of the drive motor is connected to the cam 31 and the drive motor is used to drive the cam 31 to rotate. The cam 31 has a sliding groove 311. The drive rod 32 moves along the sliding groove 311. The other end of the drive rod 32 is connected to the support plate 2.

[0049] In this embodiment, the shake bottle box 1 is a rectangular box with an internal storage slot 11. The storage slot 11 is a groove adapted to the shape of the shake bottle 12 and is used to place and fix a single shake bottle 12. A fixing component 13 is provided on the upper edge of the shake bottle box 1. The fixing component 13 is used to fix multiple shake bottle boxes 1 in the vertical direction when they are stacked.

[0050] The support plate 2 is a plate-like structure that supports the stacked shaker box 1. Multiple limiting holes are arrayed on its surface. These limiting holes are cylindrical through holes used to accommodate telescopic limiting pins 21. Each telescopic limiting pin 21 is a columnar component that can move axially along the limiting hole. Its bottom is connected to the limiting hole via a spring 22, with both ends of the spring 22 abutting against the limiting pin and the bottom of the hole, providing elastic restoring force. When the shaker box 1 is placed on the support plate 2, the telescopic limiting pins 21 located below the shaker box 1 retract into the limiting hole, while the telescopic limiting pins 21 around the box that are not covered remain extended, thus limiting the horizontal displacement of the shaker box 1.

[0051] The cam 31 is a disc with a sliding groove 311 on its edge. The sliding groove 311 is a closed curved track off the center of the circle, and the track of the sliding groove 311 is not a perfect circle. By changing the movement speed of the drive rod 32 through the asymmetrical track, the support plate 2 is moved back and forth, which improves the uniformity of liquid mixing. One end of the drive rod 32 is embedded in the groove and slides along the track, and the other end is connected to the support plate 2. It is used to convert the rotation of the cam 31 into the reciprocating motion of the support plate 2. By connecting and transmitting power and adjusting the direction of motion, it ensures that the stacked shaker box 1 oscillates synchronously. The output shaft of the drive motor is connected to the cam 31. By rotating the cam 31, the drive rod 32 is driven to swing periodically, thereby driving the support plate 2 and the stacked shaker box 1 to reciprocate.

[0052] The shake flask device provided in this embodiment can be used for microbial culture in biopharmaceuticals, solution mixing in chemical synthesis, water quality analysis in environmental monitoring, component extraction in food inspection, nano-dispersion in materials science, and dye dispersion or desizing in textile processing. Taking textile processing as an example, the working process of this device can be understood as follows: the textile sample to be tested (such as dyed fabric fragments) and the chemical treatment liquid are placed together in the shake flask 12, and the shake flask 12 is placed in the storage slot 11 of the shake flask box 1. Multiple samples are processed simultaneously by stacking and fixing them. After the drive motor is started, the cam 31 drives the drive rod 32 to make the support plate 2 and the stacked shake flask box 1 reciprocate, so that the liquid in the shake flask 12 is in full contact with the textile sample, accelerating the pretreatment reactions such as desizing, rinsing or dye dispersion. After the processing is completed, the sample is taken out for subsequent testing.

[0053] This embodiment achieves efficient parallel processing of multiple samples through the stacked design of the shake flask chamber 1 and the array of limiting holes in the support plate 2, significantly improving space utilization. The telescopic limiting pin 21 selectively retracts or extends when the shake flask chamber 1 is stacked, avoiding vertical pressure interference and limiting horizontal displacement through elastic contact, ensuring the stability of the chamber during oscillation. The non-circular sliding groove 311 of the cam 31 causes the support plate 2 to reciprocate, simulating the variable speed characteristics of artificial oscillation, enhancing the liquid turbulence effect, and meeting the deep wetting requirements of the sample and liquid. The cooperation between the drive rod 32 and the cam 31 converts the rotational motion into a controllable oscillation, making the stacked chambers oscillate synchronously and ensuring the uniformity of sample processing in each layer. When operating this device, only the shake flask chamber 1 needs to be placed and the drive motor started, without the need to adjust the fixed structure layer by layer, improving the convenience of use. While simplifying the operation process, it is also compatible with shake flasks 12 of different specifications, meeting the high-efficiency requirements of multi-sample and multi-batch processing.

[0054] In some embodiments, the fixing component 13 includes a first torsion spring 131, a supporting section 132, and a fixing section 133. The supporting section 132 and the fixing section 133 are connected to each other and perpendicular to each other to form an L-shape. The upper edge of the shaker box 1 is rotatably connected to the L-shaped fixing component 13. One end of the first torsion spring 131 is connected to the L-shaped fixing component 13, and the other end of the first torsion spring 131 is connected to the side wall of the shaker box 1. The fixing component 13 is used to limit the position of the shaker box 1.

[0055] In this embodiment, the supporting section 132 and the fixing section 133 of the fixing component 13 are perpendicular to each other and are bent to form an L-shaped structure; the first torsion spring 131 refers to the spring 22 element sleeved on the hinge shaft, one end of which is fixed to the end of the supporting section 132 of the L-shaped fixing component 13, and the other end is connected to the mounting seat on the side wall of the shaker box 1. When there is no external force, the supporting section 132 is tilted upward by elastic force. At this time, the fixing section 133 is tilted upward to form an enlarged opening area, which makes it easy for the upper and lower shaker boxes 1 to be stacked quickly without precise alignment.

[0056] When the upper shaker box 1 is pressed down, its bottom contacts the support section 132 and forces the L-shaped fixing component 13 to rotate downward until the support section 132 is pressed to a horizontal state. At this time, the support section 132 is sandwiched between the upper and lower shaker boxes 1, while the fixing section 133 is perpendicularly attached to the outer wall of the upper shaker box 1, and the horizontal displacement is limited by the contact between the L-shaped bend and the edge of the shaker box 1. The first torsion spring 131 is compressed and stores energy during this process. When the upper shaker box 1 is removed, its elastic force drives the L-shaped fixing component 13 to automatically rebound to the initial tilted state, restoring the quick alignment function.

[0057] In this embodiment, the elastic reset characteristic of the first torsion spring 131 and the mechanical limiting of the L-shaped structure are combined to make the fixing component 13 tilt up when there is no external force, thereby expanding the opening area and improving the stacking alignment efficiency. When the box is pressed down, the fixing section 133 is vertically attached to the box to limit the displacement, and the first torsion spring 131 stores energy to ensure automatic reset after removal, which not only improves the stacking efficiency but also ensures the stable fixation of the multi-layer box during the oscillation process.

[0058] In some embodiments, a hook is provided at the end of the fixing section 133 away from the supporting section 132, and a slot is provided at the opposite position of the shaker body 1, and the hook and the slot are adapted to fix the other shaker body 1 above.

[0059] In this embodiment, the hook and slot work together to achieve double limiting when the L-shaped fixing component 13 is pressed down. Specifically, the fixing segment 133 is vertically attached to the outer wall of the upper shaking flask box 1, and the hook at its end is precisely embedded in the preset slot of the lower shaking flask box 1, forming a horizontal mechanical lock, which effectively prevents the box from sliding or misaligning laterally during oscillation. The elastic reset characteristic of the first torsion spring 131 causes the fixing component 13 to automatically return to its initial state when there is no external force. At this time, the hook disengages from the slot, and the fixing segment 133 tilts upward to form an enlarged opening area, which facilitates the quick placement of the upper shaking flask box 1 without the need for precise alignment with the slot position.

[0060] This embodiment utilizes the rigid fit between the hook and the slot to improve the stability of multi-layer box stacking, and drives the L-shaped fixing component 13 to dynamically switch states through the first torsion spring 131, taking into account both ease of operation and fixation reliability, and avoiding the problems of time-consuming installation or accidental unlocking caused by the difficulty of alignment in traditional buckle structures.

[0061] In some embodiments, the lower edge of the card slot is chamfered.

[0062] In this embodiment, when the shaker box 1 is lifted upwards, the chamfered structure guides the hook to smoothly exit the slot along the chamfered surface, avoiding a hard collision between the hook and the right-angled part of the slot or the generation of lateral resistance. This ensures that the hook naturally disengages from the locked state during the vertical lifting of the box, preserving the stability of the hook and slot when horizontally locked. Furthermore, the separation path is optimized through geometric transition, so that the unlocking action does not require additional force or angle adjustment. This effectively solves the problem of easy jamming in traditional right-angle slots, balancing the reliability of fixation and the convenience of disassembly, and improving the loading and unloading efficiency of the shaker box 1.

[0063] In some embodiments, there are multiple storage slots 11, and an L-shaped retaining plate 111 and a second torsion spring are provided on the upper edge of the storage slot 11. The L-shaped retaining plate 111 is rotatably connected to the storage slot 11, one end of the second torsion spring is connected to the L-shaped retaining plate 111, and the other end of the second torsion spring is connected to the inner wall of the storage slot 11. The L-shaped retaining plate 111 is used to fix the shaker 12.

[0064] In this embodiment, by setting multiple storage slots 11 and matching L-shaped clamping plates 111 and second torsion springs, the fixing efficiency and stability of the shaker 12 are significantly improved. Multiple storage slots 11 can simultaneously accommodate multiple sets of shakers 12, meeting the needs of batch operations. Under the elastic reset action of the second torsion spring, the L-shaped clamping plate 111 of each storage slot 11 automatically deflects inward, using its vertical L-shaped structure to abut against the bottom edge of the shaker 12, facilitating the placement of the shaker 12. After the shaker 12 is placed, the two ends of the clamping plate contact the surface of the shaker 12, forming a stable limit and preventing the shaker 12 from detaching from the storage slot 11 due to inertia during oscillation or movement. The elastic characteristics of the second torsion spring allow the L-shaped clamping plate 111 to adaptively adjust the clamping angle according to the size differences of the shaker 12, ensuring uniform clamping force while avoiding damage to the shaker 12 due to rigid compression. After use, the shaker 12 can be directly removed, and the reset force released after the second torsion spring's energy storage deformation can quickly restore the clamping state, simplifying the operation process and eliminating the need for manual adjustment of the locking mechanism. This device achieves efficient batch fixing and rapid storage and retrieval of shaker bottles 12 through the synergistic effect of elasticity and mechanical limiting, while taking into account ease of operation, structural reliability and equipment versatility.

[0065] In some embodiments, a cushioning pad 112 is provided at the bottom of the storage compartment 11.

[0066] In this embodiment, the buffer pad 112, made of elastic material, absorbs the vertical impact force generated during the placement or shaking of the shaker 12, reducing the instantaneous stress when the bottom of the shaker 12 is in rigid contact with the storage groove 11, thus preventing the bottle from breaking due to high-frequency vibration or accidental impact. Simultaneously, the surface of the buffer pad 112 forms a high-friction fit with the bottom of the shaker 12, limiting the horizontal sliding of the shaker 12 and enhancing its stability. Furthermore, the elastic deformation characteristics of the buffer pad 112 can adapt to the bottom contours of shakers 12 of different sizes, ensuring universality of the cushioning effect and balancing the protection of the shaker 12 with operational safety.

[0067] In some embodiments, the drive motor is a variable frequency speed control motor.

[0068] In this embodiment, the variable frequency speed control motor achieves wide-range precise control of the rotation speed by continuously adjusting the output frequency, so that the oscillation frequency of the shaking flask 12 can be flexibly adjusted according to experimental needs to meet the differentiated requirements of oscillation intensity for different culture conditions or reaction processes; its smooth start-stop characteristics reduce mechanical shock, reduce wear of transmission components, and extend equipment life; at the same time, the high efficiency and energy-saving characteristics of variable frequency speed control reduce operating energy consumption, improve equipment economy, and take into account experimental accuracy, operational adaptability and long-term operational stability.

[0069] In some embodiments, a transparent observation window is provided on the side of the shake flask housing 1 for observing the shake flask 12.

[0070] In this embodiment, the transparent observation window allows operators to visually monitor the internal state of the shake flask 12 in real time (such as the turbidity of the culture medium, the distribution of sediment, or the formation of bubbles) without frequently opening the chamber and disrupting the stability of the internal environment. Its transparent material ensures visibility while maintaining the airtightness of the chamber, preventing the intrusion of external contaminants or fluctuations in internal temperature and humidity, and reducing the risk of experimental interference. In addition, operators can safely observe the dynamics of the shake flask 12 from a distance, reducing the risk of mechanical collisions or liquid splashes that may occur when directly contacting the shaking equipment or opening the chamber, thus balancing the visual monitoring of the experimental process, operational safety, and the reliability of environmental control.

[0071] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0072] This invention provides a shaker device that achieves efficient, stable, and highly adaptable sample processing through an integrated stacked structure, dynamic limiting, and variable speed drive system. The stacked design of the shaker housing 1, combined with the array of limiting holes in the support plate 2 and the elastic contraction and extension characteristics of the telescopic limiting pins 21, enables parallel processing of multiple samples and efficient space utilization. Selective limiting avoids vertical pressure interference and restricts horizontal displacement, ensuring the stability of the stacked housing's oscillation. The non-circular sliding groove 311 of the cam 31 drives the support plate 2 to generate variable speed reciprocating motion, simulating the variable speed characteristics of artificial oscillation, enhancing liquid turbulence, and meeting the deep wetting requirements of the sample and liquid. The L-shaped fixing component 13, through the elastic reset of the first torsion spring 131 and the mechanical locking of the hook and slot, achieves rapid alignment and stable fixing during stacking. The chamfered structure optimizes the hook separation path, improving loading and unloading efficiency. The L-shaped clamping plate 111 of the storage slot 11 works in conjunction with the second torsion spring to adaptively clamp shakers 12 of different sizes. Combined with the elastic cushioning and friction limiting of the bottom buffer pad 112, it ensures both protection and reliable fixation of the shakers 12. The variable frequency speed-regulating motor meets diverse oscillation intensity requirements through wide-range precise speed adjustment. Its smooth start-stop characteristics reduce mechanical shock. Combined with the real-time monitoring function of the transparent observation window, it achieves comprehensive optimization of operational convenience, equipment durability, and energy economy while ensuring visualization and sealing of the experimental process.

It is suitable for diverse sample processing needs in fields such as biopharmaceuticals, chemical synthesis, and textile processing.
