[0002] Clean benches are critical equipment in biological laboratories and pharmaceutical production, providing a localized, dust-free, sterile, and stable working environment. With increasing experimental precision and production requirements, the cleanliness requirements for clean benches are becoming increasingly stringent. Currently, the lighting systems of clean benches are usually independent of the air filtration systems. The lamps, constantly exposed to the experimental environment, are prone to dust accumulation, affecting not only lighting performance but also potentially becoming a source of contamination. Furthermore, the disassembly and parts replacement of traditional clean benches are complex, increasing operating costs and inconvenience.

[0003] Therefore, in view of the above situation, there is an urgent need to develop a detachable ultra-clean workbench lighting and filtration device to overcome the shortcomings in current practical applications. Utility Model Content

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

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0019] The present invention provides the following embodiments. Example 1 This application discloses a detachable lighting and filtering device for a clean bench, referring to... Figure 1 The table includes table legs 1, with a worktable 2 on each of the two table legs 1. A testing mechanism 3 is provided on the worktable 2. The worktable 2 is detachably connected to the testing mechanism 3 and the table legs 1 through two sets of symmetrically arranged connecting mechanisms 4.

[0020] The working principle and beneficial effects of the above technical solution are as follows: Two table legs 1 are inserted to support and fix the workbench 2, and are detachable. The workbench 2 supports the test mechanism 3. At the same time, the workbench 2, the test mechanism 3, and the two table legs 1 are connected into a whole by two sets of symmetrically arranged connecting mechanisms 4. This connection is detachable. When disassembly or assembly is required, these main components can be separated or fixed simply by operating the connecting mechanisms 4. The lighting components in the test mechanism 3 are filtered by the air filtration components. The lighting components are in a disinfected and filtered environment for a long time, so dust accumulation will not affect the lighting effect or become a source of pollution, thus not affecting the accuracy of the test. This utility model is convenient for transportation and storage: the workbench 2, the test mechanism 3, and the table legs 1 can be separated, which greatly reduces the overall volume and facilitates packaging, transportation, and storage. It is especially suitable for laboratories with limited space or those that need to be moved. Users can quickly assemble or disassemble the entire workbench as needed. When a component is damaged (such as a single table leg 1, connecting mechanism 4, or test mechanism 3), it is not necessary to replace the whole machine; only the corresponding module needs to be replaced, reducing maintenance costs.

[0021] Example 2 Based on Example 1, such as Figures 1-3 As shown, the test mechanism 3 has a first mounting groove 21 for placing part of the connecting mechanism 4 and a second mounting groove 22 for inserting the table leg 1 on both sides. The first mounting groove 21 is connected to the second mounting groove 22. A clip 11 for inserting into the second mounting groove 22 is fixedly provided on one side of the table leg 1.

[0022] The working principle and beneficial effects of the above technical solution are as follows: The test mechanism 3 has a first mounting groove 21 (to accommodate the connecting mechanism 4) and a second mounting groove 22 (for inserting into the top of the table leg 1) on both sides. The two grooves are connected. A retaining strip 11 is fixed to the top of the table leg 1. During assembly, the retaining strip 11 on the top of the table leg 1 is aligned and inserted into the second mounting groove 22 on the side of the test mechanism 3, achieving initial positioning and connection between the table leg 1 and the test mechanism 3. The first mounting groove 21 provides space for the subsequent installation and operation of the connecting mechanism 4. The insertion method of the retaining strip 11 into the second mounting groove 22 is simple and intuitive, enabling rapid initial alignment and fixation of the table leg 1 and the test mechanism 3, laying the foundation for the subsequent locking of the connecting mechanism 4, and improving assembly efficiency. The retaining strip 11 slides within the second mounting groove 22, providing good guidance and ensuring accurate installation of the table leg 1. Simultaneously, it restricts the movement of the table leg 1 perpendicular to the insertion direction, initially enhancing structural stability.

[0023] Example 3 Based on Example 2, such as Figures 3-6 As shown, the connecting mechanism 4 includes a fixing sleeve 41. Multiple fixing sleeves 41 are fixedly disposed within the side wall of the first mounting groove 21. A limiting strip 42 is horizontally inserted into each fixing sleeve 41. One end of the limiting strip 42 is connected to the inner wall of the first mounting groove 21 via a buffer spring 422. Multiple first slots 421 are provided on the limiting strip 42. Multiple second slots 43 are formed on the top of the first mounting groove 21 corresponding to the multiple first slots 421. Multiple third slots 44 are formed on the top of the table leg 1 corresponding to the multiple first slots 421. The upper and lower ends of each first slot 421 are respectively fixed with... A tension spring 45 is provided, and a locking block 46 is fixedly provided at the other end of the tension spring 45. A rotating plate 47 is rotatably provided on one side of the worktable 2. An arc-shaped groove 48 is fixedly provided on the rotating plate 47. An extension post 49 is fixedly provided on the limiting strip 42 at the end away from the buffer spring 422. The extension post 49 is inserted into the arc-shaped groove 48. A locking post 50 is fixedly provided on the extension post 49 extending out of the arc-shaped groove 48. An arc plate 51 is fixedly provided on the rotating plate 47 on one side of the arc-shaped groove 48. A lifting groove 52 is provided on the arc plate 51. The locking post 50 is inserted into the lifting groove 52. A rotating handle 53 is also fixedly installed on the rotating plate 47. The rotating plate 47 is disc-shaped and has a clearance groove 54.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the first mounting groove 21 fixes multiple fixing sleeves 41, the multiple fixing sleeves 41 vertically fix the limiting strip 42, and one end of the limiting strip 42 is connected to the groove wall through a buffer spring 422, so that the limiting strip 42 can be extended and retracted.

[0025] The limiting strip 42 has multiple first slots 421, and each of its upper and lower walls is connected to a tension spring 45. The end of the tension spring 45 is fixed with a block 46. Under normal conditions, when the buffer spring 422 is compressed by the limiting strip 42, and the first slot 421 is aligned with the second slot 43 and the third slot 44, the tension spring 45 causes the block 46 to enter the second slot 43 and the third slot 44. The tension spring 45 in this application is a high-strength spring, which meets the requirement of the tension spring 45 connecting to the block 46, so that the test mechanism 3 and the two table legs 1 are fixed by the combination of the limiting strip 42, the tension spring 45, the block 46, the second slot 43 and the third slot 44.

[0026] The workbench 2 provides rotational support for the rotating plate 47. The other end of the limiting strip 42 has an extension post 49 that is inserted into the arc-shaped groove 48, and the end of the extension post 49 has a locking post 50.

[0027] An arc-shaped plate 51 with a lifting groove 52 is fixed on the rotating plate 47, and the locking post 50 is inserted into the lifting groove 52.

[0028] The procedure for unlocking or locking the testing mechanism 3 and the two table legs 1 is as follows: Unlock: Hold the rotating handle 53 and rotate it. The rotating plate 47 drives the arc-shaped groove 48 and the arc-shaped plate 51 to rotate synchronously. The arc-shaped groove 48 fixes the locking post 50 and the extension post 49. The specific trajectory of the lifting groove 52 of the extension post 49 forces the locking post 50 and the extension post 49 to move away from the buffer spring 422. The buffer spring 422 is not under pressure and extends. At the same time, the buffer spring 422 drives the limiting bar 42 to move away from the buffer spring 422. The limiting bar 42, through the tension spring 45, moves the locking block 46 from the second... Pull out from the slots 43 and 44. The first slot 421 is staggered from the second slot 43 and 44. The first mounting slot 21 abuts against the block 46. The block 46 compresses the tension spring 45. When the block 46 enters the first mounting slot 21, the test mechanism 3 and the two table legs 1 are unlocked and become detachable. After unlocking, the rotating plate 47 has an avoidance groove 54 facing the position of the clip 11, which avoids the pull-out of the clip 11 and prevents the rotating plate 47 from interfering with the pull-out of the table legs 1.

[0029] Locking: Reverse rotation of handle 53 causes limit bar 42 to move closer to buffer spring 422 under the action of buffer spring 422, compressing buffer spring 422. At the same time, the trajectory of lifting groove 52 guides the movement of locking post 50 and extension post 49, so that the first locking groove 421 is aligned with the second locking groove 43 and the third locking groove 44 synchronously. The first mounting groove 21 does not abut against the locking block 46. The tension spring 45 extends to push out the locking block 46. When the locking block 46 enters the second locking groove 43 and the third locking groove 44, the test mechanism 3 and the two table legs 1 are locked and become non-removable.

[0030] By performing the same operation on both sides, the testing mechanism 3 and the two table legs 1 can be unlocked and locked.

[0031] Single-action multi-directional locking: By simply turning a handle, the ingenious arc groove 48 and lifting groove 52 are linked together, simultaneously controlling the axial movement (extension) of the limit bar 42. This allows the locking block 46 to precisely insert into or disengage from the third locking groove 44 of the table leg 1 and the second locking groove 43 of the worktable 2, thus locking or unlocking the table leg 1 and the worktable 2. The operation is extremely simple and efficient. The locking block 46 simultaneously engages with the second locking groove 43 of the worktable 2 and the third locking groove 44 of the table leg 1, forming a rigid connection point. Combined with the distribution of multiple locking grooves, the connection is extremely strong, effectively resisting vibration and lateral force during operation. The buffer spring 422 can absorb the minor impacts generated during the operation or movement of the worktable, protecting the connection structure, extending its life, and improving stability. The tension spring 45 ensures that the locking block 46 always has a tendency to tighten outward in the locked state, preventing accidental loosening due to vibration.

[0032] Example 4 Based on Example 4, such as Figures 4-7 As shown, a fixing block 55 is also provided on the rotating plate 47, and a fixing post 56 is fixedly provided on one side of the fixing block 55. Two sets of clamping components 57 for clamping the test mechanism 3 are provided on the top of the test mechanism 3. The clamping assembly 57 includes a rotating frame 571, which is fixedly mounted on the top of the test mechanism 3. A transmission plate 572 is rotatably mounted on the rotating frame 571. A counterweight 578 is fixedly mounted on the side of the transmission plate 572 away from the test mechanism 3. A rotating block 573 and a toggle rod 574 are respectively hinged to both ends of the transmission plate 572. A clamping plate 575 is slidably mounted on the rotating block 573. A moving groove 576 is opened on the side of the clamping plate 575 facing the transmission plate 572. Limiting pieces 577 at both ends of the rotating block 573 are slidably mounted in the moving groove 576.

[0033] The working principle and beneficial effects of the above technical solution are as follows: the rotating plate 47 supports the fixed block 55, the fixed block 55 supports and fixes the fixed column 56, and the clamping mechanism is started by rotating the fixed column 56, thus completing the clamping and releasing of the clamping mechanism on the test mechanism 3. The workbench 2 provides fixed support for the rotating frame 571, the rotating frame provides rotational support for the transmission plate 572, one end of the transmission plate 572 provides fixed support for the counterweight block 578, the other end of the transmission plate 572 is movably connected to the rotating block 573, and the clamping plate 575 provides sliding limit for the rotating block 573.

[0034] When the rotating plate 47 rotates to the locked position, the fixed column 56 moves the lever 574 during this process. When the rotating plate 47 rotates away from the worktable 2, the end of the transmission plate 572 with the counterweight 578 changes from the pressed state to the raised state. The other end of the transmission plate 572 pushes the rotating block 573 to press down in the moving groove 576 on the clamping plate 575 and drives the clamping plate 575 to press down. The clamping plates 575 at both ends press down to firmly clamp and fix the middle test mechanism 3 on the worktable 2. When the rotating plate 47 rotates to the unlocked position, the fixed column 56 moves away from the lever 574 during this process. The end of the transmission plate 572 with the counterweight 578 becomes pressed down. The transmission proceeds in reverse according to the above transmission method. The clamping plate 575 rises, and the clamping plates 575 at both ends loosen their fixation on the test mechanism 3, which facilitates the removal of the test mechanism 3 and improves the overall assembly or disassembly efficiency. The clamping assembly 57 provides additional and special clamping force to ensure that the test mechanism 3 (experiment box 31) placed on the table will not move or shake, ensuring the stability of the clean working environment and operational safety.

[0035] Example 6 Based on Example 5, such as Figures 7-9 As shown, the experimental mechanism 3 includes an experimental chamber 31, which is mounted on the workbench 2. A lighting assembly 32 and an isolation lamp cover 33 are inserted into the top of the experimental chamber 31. The isolation lamp cover 33 covers the outside of the lighting assembly 32. A feed inlet 34 is provided on the top of the experimental chamber 31. An isolation cover 35 is fixedly installed on the inner wall of the top of the experimental chamber 31 corresponding to the feed inlet 34. A disinfection assembly 423 is provided on the inner wall of the isolation cover 35. Sealing caps 424 are rotatably installed at the bottom of the feed inlet 34 and the isolation cover 35, respectively. Two operating holes 425 are provided on the side wall of the experimental chamber 31. An operating glove 36 is sealed on the side of the operating hole 425 facing the inside of the experimental chamber 31. A ventilation hole is provided on the other side wall of the experimental chamber 31. The ventilation hole is connected to the air inlet of the air filter assembly 37 fixedly installed on the outside of the experimental chamber 31.

[0036] The working principle and beneficial effects of the above technical solution are as follows: The lighting assembly 32 and the isolation lamp cover 33 are connected by a plug-in method, which facilitates the assembly and disassembly of the lighting assembly 32 and the isolation lamp cover 33. The isolation lamp cover 33 protects the lighting assembly 32. There is a feed inlet 34 at the top, and an isolation cover 35 is installed inside. The inner wall of the isolation cover 35 has a disinfection component 423 (such as a UV lamp or spray nozzle) to disinfect the incoming items. Both the feed inlet 34 and the bottom of the isolation cover 35 have rotating sealing caps 424 to maintain airtightness. There is an operation hole 425 on the side wall, and an operation glove 36 is installed on the inner side to allow personnel to put their hands into the box for aseptic operation, while isolating the internal and external environments.

[0037] The ventilation holes on the other side wall are connected to the air filter assembly 37 (such as a HEPA / ULPA filter) to continuously filter the air in the box or maintain positive or negative pressure, expel polluted air, and ensure internal cleanliness.

[0038] The integrated ultra-clean environment combines lighting, material transfer and disinfection, aseptic operation of personnel, and air filtration and purification to provide a clean working space that meets the standards for experiments. The lighting components are set within the range of the air filter components 37. The lamps are easily exposed to dust in the experimental environment for a long time, which not only affects the lighting effect, but may also become a source of pollution.

[0039] The isolation lamp cover 33 prevents light source contamination; the double-layer sealing cover 424 (feed inlet 34 and bottom of isolation cover 35) combined with the disinfection component 423 strictly controls contamination during the material transfer process; the operating gloves 36 ensure that personnel operation does not damage the sterile environment; the air filtration component 37 continuously maintains the cleanliness of the air inside the chamber.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
