Description

Technical Field

[0001] This application relates to the field of vortex instrument technology, and in particular to a vortex oscillation device. Background Technology

[0002] In many work scenarios such as medical treatment, laboratory work, and scientific research, it is often necessary to mix containers containing different solutions or reagents to improve the uniformity of solution mixing or the overall dissolution effect of reagents. Vortex oscillation devices play a crucial role in this process. They promote thorough mixing of substances within the container by generating specific oscillating motions.

[0003] Related technology can be found in CN202320843000.2, which discloses a vortex oscillation device for liquid chromatography vials. The liquid chromatography vial is movably mounted on a sample tray, and the device includes a vortex oscillator, an oscillation disk, a positioning mechanism, and a fixing mechanism. The oscillation disk is mounted on the vortex oscillator; the positioning mechanism is mounted on the oscillation disk for positioning the sample tray; and the fixing mechanism is detachably mounted on the oscillation disk for detachably fixing the liquid chromatography vial to the sample tray and the sample tray to the oscillation disk. However, such existing vortex oscillation devices have some significant drawbacks. First, their structure is relatively complex, consisting of multiple components working together. Multiple components, such as the positioning mechanism and fixing mechanism in the aforementioned device, increase the overall complexity of the device, not only increasing the difficulty and cost of manufacturing but also making subsequent maintenance and repair work cumbersome. Second, they occupy a large space. The complex structural design requires a significant amount of space when placed, which is undoubtedly a disadvantage for laboratories or work areas with limited space. Third, in practical applications, vortex oscillation devices are often used in conjunction with other detection devices to meet diverse experimental or detection needs. However, due to structural design and other reasons, existing devices cannot be flexibly assembled with other detection devices, limiting their application in integrated experimental or detection processes and making it difficult to efficiently build an integrated detection system.

[0004] To address the aforementioned problems, this invention proposes a vortex oscillation device that occupies a small area and can be flexibly assembled with other detection devices. Utility Model Content

[0018] The present application will be further described in detail below with reference to all the accompanying drawings.

[0019] This application discloses a vortex oscillation device.

[0020] Reference Figure 1 A vortex oscillation device includes: a support assembly, an oscillation motor 3, and a sample holder 4.

[0021] Reference Figure 1The supporting components include a base plate 1, which serves as the basic load-bearing structure of the device, and two sets of symmetrically arranged upright plates 2 fixed on the base plate 1. The symmetrical layout can not only evenly bear the load of the sample rack 4 and the samples it carries, ensuring the stability of the device operation, but also provide suitable space for the installation of the sample rack 4 through a compact spacing design, effectively reducing the lateral occupancy size and realizing efficient spatial integration of the supporting structure and functional components.

[0022] The oscillating motor 3 is fixedly installed on the outside of the upright plate 2. This installation method avoids the motor occupying the core operating space inside the device, so that the internal space of the device can be concentrated on the arrangement of the sample rack 4. The output end of the oscillating motor 3 passes through the upright plate 2 and extends along the inner side of the upright plate 2 for a preset length. This preset length design not only ensures the reliable connection between the output end and the sample rack 4, but also avoids the space redundancy caused by the output end being too long. By externalizing the power source and shortening the distance of the power transmission structure, the space utilization efficiency of the device is significantly improved.

[0023] The sample rack 4 is rotatably connected between the two sets of upright plates 2. The output end of the oscillating motor 3 is fixedly connected to the sample rack 4. This direct power transmission structure reduces intermediate transmission components, which not only reduces energy loss, but also achieves a compact structure due to the lack of space occupied by the additional transmission mechanism. The sample rack 4 is provided with slots for placing sample tubes 9. The slots provide a precise positioning and accommodating space for the sample tubes 9, enabling the orderly arrangement of the sample tubes 9. The side wall of the sample rack 4 is provided with fixing springs 5. A spring top ball structure 6 is embedded in the sample rack 4 at the slot. The two form a synergistic clamping effect, which can stably limit the position of sample tubes 9 of different specifications. Moreover, this type of elastic clamping structure does not require complex adjustment components. While ensuring reliable fixation of the sample tubes 9, it greatly simplifies the structural size of the sample rack 4 and further reduces the overall space occupied by the device.

[0024] This sample oscillation device, through the integrated layout and compact design of its various structures, significantly optimizes the spatial configuration while ensuring the efficient realization of the sample oscillation function, achieving the goal of a compact structure and small footprint.

[0025] Reference Figure 1 A baffle 7 is fixed on the base plate 1, which can limit the sample rack 4 and sample tube 9 in a specific direction, effectively preventing them from undergoing unexpected displacement, enhancing the positioning stability of the overall structure, and ensuring that the positional accuracy meets the preset requirements during sample processing.

[0026] Reference Figure 1 A zero-position switch 8 is provided between the two sets of upright plates 2. The zero-position switch 8 is located below the sample rack 4 and is at a preset distance from the sample rack 4. It can be accurately triggered when the sample rack 4 returns to its initial position, providing a reference position signal for the equipment, realizing accurate calibration of the position of the sample rack 4, and ensuring the consistency of the coordinate reference for subsequent operations.

[0027] Reference Figure 1 The fixing spring 5 is an elastic metal sheet with good elastic deformation capability to adapt to the fixing of sample tubes 9 of different specifications. With its good elastic deformation capability, it can generate adaptive deformation for the outer diameter of sample tubes 9 of different specifications. It forms a stable clamping of sample tubes 9 through its own elastic restoring force, which expands the compatibility range of the device with sample tube 9 specifications while ensuring the reliability of fixing.

[0028] Reference Figure 1 The spring-top ball structure 6 includes a spring and a top ball. The spring provides elastic force to make the top ball abut against the side of the sample tube 9. The force between the top ball and the sample tube 9 restricts the radial sway of the sample tube 9 and improves the stability of the sample tube 9. On the other hand, by utilizing the elastic buffering characteristics of the spring, rigid compression damage to the sample tube 9 can be avoided. At the same time, it can adapt to the slight differences in the outer diameter of the sample tube 9 and enhance the versatility of the fixing structure.

[0029] The working principle of the vortex oscillation device in this embodiment is as follows: In terms of power transmission, the oscillation motor 3 serves as the power source and is fixedly mounted on the outside of the upright plate 2. Its output end passes through the upright plate 2 and is fixedly connected to the sample holder 4. When the oscillation motor 3 starts, the output end directly transmits the driving force to the sample holder 4, causing the sample holder 4 to rotate between the two sets of upright plates 2, thereby realizing the vortex oscillation operation of the sample tube 9 placed on the sample holder 4. For the fixing and limiting of the sample tube 9, the slot on the sample holder 4 provides the initial positioning and accommodating space for the sample tube 9. The fixing spring 5 on the side wall of the sample holder 4 is an elastic metal sheet with good elastic deformation capability. When the sample tube 9 is placed into the slot, the fixing spring 5 will undergo adaptive deformation according to the outer diameter of the sample tube 9, and form a clamping force on the sample tube 9 through its own elastic restoring force. At the same time, the sample holder 4 The spring-loaded ball structure 6, which is embedded at the slot position, provides elastic force to make the ball abut against the side of the sample tube 9, generating a clamping force in another direction. The fixing spring 5 and the spring-loaded ball structure 6 work together to form a stable clamping of the sample tube 9, which can adapt to the fixing requirements of sample tubes 9 of different specifications, effectively limiting the radial sway of the sample tube 9 during the oscillation process and ensuring the stability of the sample tube 9. The baffle 7 fixedly installed on the base plate 1 forms a limiting constraint on the sample holder 4 and the sample tube 9 in a specific direction during the vortex oscillation process, preventing unexpected displacement and ensuring the positional accuracy during sample processing.

[0030] In summary, through the synergistic effect of its components, the device achieves effective sample oscillation while ensuring operational stability and spatial adaptability through its compact structural design and vibration control mechanism, thus meeting the requirements for compatibility with other devices.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
