Description

Technical Field

[0001] This invention relates to the field of medical device technology for the batch automated recycling of consumables, specifically to a telescopic drive mechanism, a recycling drawer, and a recycling module. Background Technology

[0002] In vitro diagnostics (IVD), as a diagnostic approach that uses ex vivo samples for testing, is seeing increasing public awareness of health and a broader range of diseases that can be detected. The growing demand for larger sample volumes and increasing testing needs make automated batch processing systems a future trend. These systems typically feature high integration and complexity, but are relatively simple to operate, with low human intervention throughout the testing process. They can essentially achieve the goal of efficient, closed-loop sample processing. Achieving this efficiency relies on the automated coordination of different sub-functional modules within the system. Among these, pipetting consumables, being the most important consumables that directly contact the sample, require highly efficient automated processing solutions.

[0003] Currently, different manufacturers have designed different structures for both the addition of pipetting consumables and the recycling of used pipetting consumables. The earliest pipetting consumable addition followed the design schemes of different sample processing or dispensing module equipment, configuring pipetting consumables on multiple horizontally arranged pipetting consumable racks. This design requires placing pipetting consumable boxes one by one on the consumable racks. Some consumable racks also need to be equipped with locking and fixing structures inside the consumable racks because they need to be used in conjunction with the pipetting module to load pipetting consumables. This results in low efficiency in loading and configuring pipetting consumables, which is unacceptable for high-volume processing systems. Driven by factors such as research on some large-scale equipment abroad and the need to improve space utilization, a scheme for vertically stacking pipetting consumables and other consumables such as extraction magnetic rod sleeves has been developed. This design only requires the operator to add the corresponding consumable boxes in batches at specific times. Other operations such as consumable box transfer, consumable loading, unloading, and recycling are all performed automatically by the system.

[0004] Chinese invention patent CN110068696A designs a consumable stacking and loading mechanism, including a vertically parallel operating full-disc lifting drive mechanism and an empty-disc lifting and retrieval drive mechanism. This design integrates loading and retrieval into the same module, offering some operational convenience. However, this design does not address the collection and processing structure for used pipetting consumables. This structure is similar to Roche's Chinese invention patent application CN112313516A, except that Roche uses an empty-disc locking and retrieval mechanism located on the top of the stacked pipetting consumable boxes, and the pipetting module can be driven to the area between the stacked pipetting consumable boxes and the empty-disc stacked area to perform pipetting consumable loading and retrieval. This design also has higher space utilization, but it places special requirements on the module design of a streamlined system. Furthermore, the pipetting module requires sufficient driving space, and this design may result in the final empty pipetting consumable storage area being very high vertically, which is not conducive to operation. Chinese invention patent CN103698546B, in its authorized solution, designs a transfer module similar to a horizontal conveyor belt, and configures... With a locking structure, pipetting consumable boxes loaded at different positions on the conveyor belt can be locked and fixed. As the conveyor belt rotates, the pipetting consumable boxes are moved to a fixed pipetting consumable loading position. After the pipetting consumables are loaded at the loading position, the transport vehicle connected in series can transfer the empty box to the storage box. This structure is a simple serial layout. However, none of the above designs cover the recycling design of the pipetting consumables themselves. In automated systems, different types of pipetting consumables are often used to transfer different liquids. Since pipetting consumables come into direct contact with liquids, the risk of contamination is high. A centralized pipetting consumable collection structure is the design goal. However, collecting different types of pipetting consumables means that the recycling drawer needs to have a large volume. Since the power of the sterilization lamp is fixed, the light intensity per unit area is higher. In order to ensure that the collected pipetting consumables are more thoroughly sterilized, the collection drawer needs to be driven by a small stroke. The processing of collected consumables requires the operator to have sufficient operating space. This requires a special design for the pipetting consumable recycling drive structure to meet this requirement.

[0005] Therefore, there is an urgent need to design a drive mechanism suitable for the pipetting consumables recycling drawer in a batch processing system, so as to meet the requirement of increasing the travel length of the recycling box so that the recycling drawer can be closer to the consumables recycling port, thereby achieving the goal of efficient and reliable recycling of pipetting consumables.

[0006] Telescopic drive mechanisms are widely used because they have autonomous driving power and can achieve precise position driving without human intervention. For example, in the home appliance industry, high-end refrigerators and dishwashers are equipped with telescopic drive mechanisms, which enable the storage chamber to be automatically driven to a specific position for easy access to items. In the automotive consumer goods industry, high-end passenger vehicles equipped with electric doors driven by telescopic drive mechanisms can greatly improve the passenger riding experience. The configuration of telescopic drive mechanisms can also solve the problem of human limitations in special scenarios with high pollution risks or excessive operating resistance. In the medical field, the handling of large quantities of waste consumables is a high-pollution risk scenario, and the application of automated telescopic drive mechanisms is essential. However, the integration of large-scale sample processing systems is very high, so the space for telescopic drive mechanism configuration is very limited, but there are also requirements for the storage volume of the storage containers. Therefore, the design of long-stroke telescopic drive mechanisms is essential. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems by providing a telescopic drive mechanism, a recycling drawer, and a recycling module. When the moving base plate is driven to displacement, the driving force can be transmitted to the sliding support platform via a range extender unit. A single drive motor can simultaneously drive both the moving base plate and the sliding support platform. Furthermore, different transmission ratios can be adjusted by setting the number of teeth on the first and second transmission components. The first and second transmission components at both ends of the range extender unit can generate relative movements with the first and second drive transmission units of different stroke lengths. In addition, this invention optimizes the consumable recycling and transfer path by maximizing the proximity of the recycling drawer unit to the consumable receiving port within a limited space, while also ensuring that the overall structure does not waste excessive space.

[0008] The technical solution adopted in this invention is as follows:

[0009] A telescopic drive mechanism includes a fixed base plate, a movable base plate, a sliding support platform, a range extender unit, and a drive unit. The range extender unit is matched with the fixed base plate via a first drive transmission unit and with the sliding support platform via a second drive transmission unit, and the range extender unit follows the movable base plate. When the movable base plate moves a first stroke length relative to the fixed base plate in the telescopic direction, the range extender unit can drive the sliding support platform to move a second stroke length relative to the movable base plate in the telescopic direction. The movable base plate is movably connected to the fixed base plate via a first guide device, which restricts the movement of the movable base plate relative to the fixed base plate in the telescopic direction. The sliding support platform is movably connected to the movable base plate via a second guide device, which also restricts the movement of the sliding support platform relative to the movable base plate in the telescopic direction. The drive unit can drive the movable base plate to move in the telescopic direction.

[0010] Furthermore, the range extender unit includes a central shaft, a first transmission component, and a second transmission component. The first transmission component and the second transmission component are respectively disposed at both ends of the central shaft. The first transmission component is matched with a first drive transmission unit, and the second transmission component is matched with a second drive transmission unit. The central shaft is directly or indirectly restricted to the moving base plate through a transmission bearing. When the moving base plate moves along a first stroke, the first drive transmission unit drives the first transmission component to rotate. The first transmission component drives the second transmission component to rotate through the central shaft. The second transmission component drives the sliding support platform to move by a second stroke length through the second drive transmission unit.

[0011] Furthermore, both the first and second transmission components are gears, the first drive transmission unit is a rack matched with the first transmission component, and the second drive transmission unit is a rack matched with the second transmission component.

[0012] Furthermore, the transmission ratio between the first transmission component and the second transmission component is not higher than 0.85 or not lower than 1.15.

[0013] Furthermore, the sliding support platform is also equipped with a mounting base for limiting the object being supported.

[0014] Furthermore, the side plate of the fixed substrate is provided with a side rail, which matches the movable substrate.

[0015] A recycling drawer includes a recycling drawer unit, a fixed base plate, a movable base plate, a sliding support platform, a range extender unit, and a drive unit. The recycling drawer unit is mounted on the sliding support platform. The range extender unit is matched with the fixed base plate via a first drive transmission unit and with the sliding support platform via a second drive transmission unit. The range extender unit follows the movable base plate. When the movable base plate moves a first stroke length relative to the fixed base plate in the extension direction, the range extender unit can drive the sliding support platform to move a second stroke length relative to the movable base plate in the extension direction. The movable base plate is movably connected to the fixed base plate via a first guide device, which restricts the movement of the movable base plate relative to the fixed base plate in the extension direction. The sliding support platform is movably connected to the movable base plate via a second guide device, which also restricts the movement of the sliding support platform relative to the movable base plate in the extension direction. The drive unit can drive the movable base plate to move in the extension direction. The recycling drawer unit has a recycling material transfer port.

[0016] Furthermore, the sliding support platform moves in the same direction as the moving substrate, the sliding support platform moves relative to the fixed substrate by the sum of the second stroke and the first stroke, the moving substrate moves relative to the fixed substrate by the first stroke, and the moving stroke of the sliding support platform relative to the fixed substrate is greater than the moving stroke of the moving substrate relative to the fixed substrate.

[0017] A recycling module includes a recycling drawer unit, a fixed base plate, a movable base plate, a sliding support platform, a range extender unit, a drive unit, and a disinfection module. The disinfection module acts on the recycling drawer unit and disinfects the recyclables within it. The recycling drawer unit is mounted on the sliding support platform. The range extender unit is matched with the fixed base plate via a first drive transmission unit and with the sliding support platform via a second drive transmission unit, and moves with the movable base plate. When the movable base plate moves a first stroke length relative to the fixed base plate in the extension direction, the range extender unit can drive the sliding support platform to move a second stroke length relative to the movable base plate in the extension direction. The movable base plate is movably connected to the fixed base plate via a first guide device, which restricts its movement relative to the fixed base plate in the extension direction. The sliding support platform is movably connected to the movable base plate via a second guide device, which also restricts its movement relative to the movable base plate in the extension direction. The drive unit drives the movable base plate to move in the extension direction. The recycling drawer unit has a recyclable transfer port.

[0018] Furthermore, it also includes a negative pressure module, which has a negative pressure port that is in fluid communication with the recycling drawer unit.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. When the movable substrate of the present invention is driven to move, the driving force can be transmitted to the sliding support stage through the range extender unit. The movable substrate and the sliding support stage can be driven to move simultaneously through a single driving unit.

[0021] 2. The present invention can adjust the transmission ratio by setting the number of teeth of the first transmission component and the second transmission component. The first transmission component and the second transmission component at both ends of the range extender can generate relative motion with the first drive transmission unit and the second drive transmission unit with different stroke lengths, respectively. For example, in some scenarios, it is necessary to make the relative sliding stroke between the sliding support platform and the moving base plate larger to achieve a longer end range extension, so as to achieve the goal of more efficient and high-speed position change of the support platform. In other scenarios, there is the opposite requirement. At this time, it is only necessary to adjust the transmission ratio to meet different requirements.

[0022] 3. In scenarios where the first stroke length is greater than the second stroke length, the present invention can satisfy the requirement that the moving base plate has a long stroke to ensure sufficient operating space after the mechanism is extended, while also ensuring that the sliding support stage does not travel too long on the moving base plate, which would cause the space of the recycling drawer unit used for consumable storage to occupy too much space in other modules of the system, and also does not require reserving too much space to avoid the second drive transmission unit that exceeds the length.

[0023] 4. The range extender unit of the present invention is constrained on the moving substrate by a transmission bearing, and there is no relative movement between it and the moving substrate, thereby making the reliability of the component itself higher.

[0024] 5. The present invention utilizes gears configured at both ends of the central shaft as the first transmission component and the second transmission component, and configures the first drive transmission unit and the second drive transmission unit as racks with different preset lengths. Thus, the extended transmission with a preset transmission ratio is realized through meshing transmission. In order to achieve the preset transmission ratio, gears with the same module ratio can be used. The preset transmission ratio adjustment scheme can be realized simply by changing the number of teeth, which is more convenient to implement.

[0025] 6. This invention can optimize the consumable recycling and transfer path by maximizing the proximity of the recycling drawer unit to the consumable receiving port within a limited space, while also ensuring that the overall structure does not waste too much space.

[0026] 7. This invention eliminates the risk of contamination during consumable recycling by using a disinfection module and / or a negative pressure module. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Example 1

[0040] Figure 1This is a structural diagram of the telescopic drive mechanism provided by the present invention. The entire telescopic drive mechanism includes a fixed base plate 10, which can be connected to the base of the processing system to ensure sufficient stability. It can be made of a metal or non-metal material with specific strength. A first guide device 101 is disposed on the fixed base plate 10. The first guide device 101 is preferably a fixed slide rail fixed to the fixed base plate 10. To ensure the reliability and stability of the sliding, the first guide device 101 can be configured as a pair of parallel fixed slide rails, or more than one, which is not limited here. To achieve long-stroke drive of the first guide device 101, the moving base plate... The movable substrate 20 can be slidably fitted onto the fixed substrate 10. Here, a slider that engages and slides with the first guide device 101 can be arranged at the bottom of the movable substrate 20. The number of sliders can correspond to the number of the first guide device 101 or be two or more times the number of the first guide device 101. In this embodiment, the movable substrate 20 can at least partially stack with the fixed substrate 10 in the retracted state, thereby greatly saving space. In the unfolded state, the movable substrate 20 can be driven to extend beyond the range of the fixed substrate 10, forming an extension of the fixed substrate 10, ensuring the overall structural strength is improved, and making the object supported on the movable substrate 20 more stable.A second guide device 201 is disposed on the movable base plate 20. Preferably, the second guide device 201 is a movable slide rail that can move with the movement of the movable base plate 20. A sliding support platform 30 is slidably mounted on the movable base plate 20 via the second guide device 201. Similarly, to ensure the stability of the sliding support platform 30, the number of second guide devices 201 can be two or more. Here, the bottom of the sliding support platform 30 can also be connected to the second guide device 201 by a slider. Under normal circumstances, there is no relative movement between the sliding support platform 30 and the movable base plate 20. To achieve relative movement between the two, an independent motion drive is required to meet the difference in the movement stroke of the sliding support platform 30 and the movable base plate 20. For example, in the scenario of medical waste consumable recycling, the movable base plate 20 needs a relatively long stroke so that as many large-capacity recycling drawer units as possible can be driven and exposed. Under the premise of ensuring stable support, the operator has enough operating space to pack the recycled waste consumables. However, the sliding support platform 30 does not need to be connected to the movable base plate 20. To avoid excessively long travel, the sliding support platform 30 only needs to move the retracted mobile substrate 20 to the inner edge of the mobile substrate 20, or even closer to the consumable storage port, within a shorter relative travel distance. In the extended state, it should be closer to the outer edge of the mobile substrate 20, allowing the operator to operate without interference. It should be noted that in this application, the retraction direction of the mobile substrate 20 is taken as the reference, the retraction direction of the mobile substrate 20 is inward, and the extension direction of the mobile substrate 20 is outward. Of course, in some scenarios, the mobile substrate 20 only needs local strength reinforcement, while the sliding support platform 30 needs a longer travel distance and faster drive of the receiving object to a specific position. In these special differentiated travel scenarios, the optimal driving method is to achieve independent driving by two sets of driving forces. However, this design will have high structural and control complexity, and is not suitable for a functional module with high system integration and complexity. If the functional module adopts independent driving, it may lead to a decrease in the reliability and stability of the entire system. To solve the above problems, the drive unit of the telescopic drive mechanism of the present invention includes only one drive motor 401. Here, the drive motor 401 is fixedly mounted on the fixed base plate 10. The drive motor 401 can be a stepper motor, a brushless DC motor, etc. The output shaft of the drive motor 401 is connected to the drive transmission structure. Here, the drive transmission structure is a belt drive, but it can also be arranged as a sprocket drive, a gear and rack drive, or a lead screw drive, etc., and is not limited here.The output shaft of the drive motor 401 is connected to the drive wheel, and a driven wheel is arranged at a preset distance from the drive wheel. A transmission belt 402 is arranged between the drive wheel and the driven wheel. A connecting block 403 is connected to the transmission belt 402. The connecting block 403 can be connected to the movable base plate 20. When the drive motor rotates, the connecting block 403 is displaced with the rotation of the transmission belt 402, causing the movable base plate 20 to slide along the first guide device 101. An extension unit 13 is also fixedly connected to the movable base plate 20. The first end of the extension unit 13 is connected to a first drive transmission unit 103 disposed on the fixed base plate 10, and the second end is connected to a second drive transmission unit 303 disposed on the sliding support stage 30. Here, the second drive transmission unit 303 can be connected to the sliding support stage 30 via a fixed side plate 301. Since the drive motor 401 can cause relative movement between the movable base plate 20 and the fixed base plate 10, the extension unit 13 connected to the movable base plate 20 can also cause relative movement with the first drive transmission unit 103 fixedly connected to the fixed base plate 10. The extension unit 13 can transmit the motion drive, causing relative movement between the extension unit 13 and its connected second drive transmission unit 303. The second drive transmission unit 303 is connected to the sliding support platform 30. Therefore, the range extender unit 13 ultimately transmits the drive output from the drive motor 401, enabling the sliding support platform 30 to slide along the second guide device 201. In this way, one end of the range extender unit 13 and the first drive transmission unit 103 connected to it can be driven to generate a relative movement of a first stroke length, and the other end of the range extender unit 13 and the second drive transmission unit 303 connected to it can be driven to generate a relative movement of a second stroke length different from the first stroke length. This achieves the satisfaction of two specific transmission scenarios with different stroke ranges using a single motor. The drive and control of this structure are also relatively simple and can be applied to long-stroke drive targets in a functional module of a complex system. In order to ensure that the slide rail structure can be reliably driven and the position information can be accurately controlled, a position sensing unit 104 can also be configured on the fixed base plate 10. Of course, a position sensing unit 104 can also be configured on the movable base plate 20. The specific number is not limited here.

[0041] Figure 3The diagram below shows the structure of the range extender unit 13 provided by this invention. The range extender unit 13 includes a central shaft 130. A first transmission member 132 is disposed at the bottom end of the central shaft 130, which is connected to the first drive transmission unit 103, and a second transmission member 133 is disposed at the opposite end. The second transmission member 133 can connect to the second drive transmission unit 303. In this embodiment, the first drive transmission unit 103 and the second drive transmission unit 303 are racks with different lengths. Both the first transmission member 132 and the second transmission member 133 are gears. A transmission bearing 131 is also disposed between the first transmission member 132 and the second transmission member 133. The transmission bearing 131 is fixedly connected to the movable base plate 20. In this way, the range extender unit 13 itself does not need to undergo relative movement with the movable base plate 20 to which it is fixed, thus ensuring the reliability of the range extender unit 13 itself. The transmission of movement relies on the central shaft 130 and the first transmission member 133 at both ends of the central shaft 130. The rotation of the moving part 132 and the second transmission part 133 completes the process. In this embodiment, the first transmission part 132 and the second transmission part 133 are gears with the same module ratio. Here, a gear with a module ratio of 0.8 can be used to reduce processing costs and increase the reliability of the transmission parts. The first transmission part 132 has a greater number of teeth than the second transmission part 133 to achieve a preset transmission ratio of no more than 0.85. In this embodiment, the number of teeth of the first transmission part 132 and the second transmission part 133 can be 24 and 16, respectively. Of course, other preset transmission ratios can also be achieved by setting them to other numbers of teeth. In scenarios where rapid position adjustment is required, the number of teeth of the first transmission part 132 can be adjusted to be less than the number of teeth of the second transmission part 133 to achieve a preset transmission ratio of no less than 1.15. Of course, to ensure the reliability of the system, the preset transmission ratio is at least 0.3 and at most 3.

[0042] Example 2

[0043] Example 2 is a further improvement on Example 1; the same components will not be described again here. Figure 2This is a schematic diagram of a retrieval drawer unit 100 configured on a sliding support stage 30 driven by a telescopic drive mechanism, as provided by the present invention. Here, the telescopic drive mechanism can be applied to the retrieval drawer unit 100 for consumable retrieval. In batch sample processing systems, the retrieval of pipetting consumables is a crucial issue. The overall requirement is that the retrieval drawer unit 100 has sufficient volume so that it can be closer to the pipetting consumable delivery port after retracting back into the system. However, the pipetting consumable delivery position typically houses the drive structure and other reagent processing modules, thus limiting its space. If the retrieval drawer unit 100 is too far from the delivery port, the delivered pipetting consumable may become stuck in the channel, preventing the system from operating normally. Manual cleaning carries the risk of infection. Therefore, after the retrieval drawer unit 100 extends out of the system, it needs a large extension distance. To ensure sufficient operating space for the operator, the optimal configuration requirements in this scenario can be determined under these constraints. Specifically, the movable substrate 20 needs a relatively long first stroke length relative to the fixed substrate 10, while the sliding support platform 30, connected to the recycling drawer unit 100, needs a relatively short second stroke length relative to the movable substrate 20. To ensure the reliability of the recycling drawer unit 100 connection, the sliding support platform 30 is also equipped with a mounting base 302, which protrudes from the base of the sliding support platform 30 by a preset height. Here, the second stroke length can not exceed 0.85 times the first stroke length. To ensure smooth sliding between the movable substrate 20 and the fixed substrate 10, a side rail 102 is also provided. The side rail 102 can be similar to the side rail structure of various existing drawer units to ensure lower processing costs. The remaining... Figure 1 The same structure will not be repeated here.

[0044] Figures 4-7 This is a schematic diagram illustrating the telescopic drive mechanism of the present invention driving the retractable drawer unit 100 to different position states. Figure 4In its fully retracted state, the movable substrate 20 is almost entirely stacked on the fixed substrate 10. The recycling drawer unit 100 is driven to slide to its innermost position. At this time, the first transfer port 701 connected to the consumable transfer port can transfer the waste consumables into the recycling drawer unit 100. In order to avoid the second drive transmission unit 303 from having a through hole in the side wall of the recycling drawer unit 100 to accommodate the excess part of the second drive transmission unit 303 with sufficient drive stroke, a folding stroke layout can also be adopted, but this will make the system more complex and reduce reliability. In this position, the recycling drawer unit 100 is at least partially further inward than the movable substrate 20. Thus, even if a certain position of the recycling drawer unit 100 is stacked... Even with a large number of consumables stacked, the position of the recycling drawer unit 100 can be slightly adjusted to accommodate more pipetting consumables. Once the recycling drawer unit 100 has received a certain amount of pipetting consumables, the drive motor 401 can drive the relative motion between the moving substrate 20 and the fixed substrate 10 via a pulley transmission. At this time, the first transmission member 132 at the bottom of the range extender unit 13 also moves relative to the first drive transmission unit 103, causing the first transmission member 132 to rotate. This rotational motion is transmitted through the central shaft 130 of the range extender unit 13 to the second transmission member 133, causing the second transmission member 133 to also rotate. This, in turn, drives the second drive transmission unit 303 to move the recycling drawer unit relative to the moving substrate 20. Figures 4-7 The diagrams illustrate different positions of the retractable drawer unit 100 during its extension. Since there is a preset transmission ratio between the two first transmission components 132 and the second transmission component 133, the first drive transmission unit 103 configured here is a first rack extending a first preset length in the extension direction, and the second drive transmission unit 303 is a second rack extending a second preset length in the extension direction. The first preset length is less than the second preset length; optimally, the first preset length does not exceed 0.85 of the second preset length. This also reduces the space required for the second drive transmission unit 303, ensuring the system's compactness and reliability. Figures 7-4 The reverse can be illustrated as the process of the consumables recycling drawer retracting, which will not be elaborated here.

[0045] Figure 9 The present invention provides a packaged recycling drawer unit 100. The recycling drawer unit 100 can be surrounded by a packaged plate 111 to form a closed space. An outlet 112 can be reserved at the front. Of course, the outlet 112 can be blocked and closed by a configured door assembly to form a basically closed state. In the embodiment, the top of the recycling drawer unit 100 can include two transfer ports, such as a first transfer port 701 and a second transfer port 702, to recycle different types of pipetting consumables. Of course, the corresponding consumable recycling and delivery positions can be different, which also reduces the risk of mutual interference between different pipetting modules in the system.

[0046] Example 3

[0047] Example 3 is a further improvement on Example 2; the same components will not be described again here. Figure 8 This is a structural diagram of the recycling module provided by the present invention. Here, the movable base plate 20 includes a first base plate 210 that supports the sliding support platform 30. The bottom of the first base plate 210 can be configured with two connecting sliders connected to the first guide device 101, and the side is also connected to a second base plate 220. When the second base plate 220 is in the retracted state, it can form a cover for the drive unit to reduce the risk of contamination. A connecting block 403 is fixedly connected to the transmission belt 402 of the drive unit. The connecting block 403 is further fixedly connected to the second base plate 220 (the first base plate 210 and the second base plate 220 are light-colored for clarity). Therefore, when the drive motor 401 rotates, it can drive the movable base plate 20 to slide on the first guide device 101 through the connecting block 403. In order to further reduce the risk of contamination, the consumable recycling module is also configured with a negative pressure module 60, which includes a negative pressure port that can be fluidly communicated with the recycling drawer unit 100. Of course, the negative pressure module 60 is also equipped with a filter component to reduce the risk of contaminants being transferred to the outside. To reduce the risk of contamination within the recycling drawer unit 100, a disinfection module 50 is also configured within the recycling module. This disinfection module 50 can emit sterilization and disinfection waves within a preset wavelength range, such as a 405nm wavelength.
