Description

Technical Field

[0001] This utility model belongs to the field of clean area microbial monitoring technology, and more specifically, it relates to a settling dish structure for deployment in Class A clean areas. Background Technology

[0002] In industries such as pharmaceuticals, food processing, and bioengineering, which have extremely high requirements for the cleanliness of the production environment, Class A clean areas, as the highest level of cleanliness, have stringent standards for the control of microbial contamination. Settling dishes, as a key tool for monitoring the amount of microbial settling in clean areas, have a structural design that directly affects the accuracy of the monitoring data and the ease of operation.

[0003] In the existing settling dish structure, the lack of separate placement for the petri dishes and lids poses several potential risks to operators conducting microbial settling monitoring in clean areas. To avoid contamination, operators must aseptically open the petri dishes and expose them to the clean environment for sampling. However, due to the lack of a dedicated placement area, operators are forced to arbitrarily place the removed lids next to the settling dish or elsewhere, easily leading to contact between the inside of the lid and non-sterile surfaces, introducing contamination and posing potential quality and safety hazards to the production process. Utility Model Content

[0004] The purpose of this invention is to provide a settling dish structure for use in Class A clean areas, which aims to solve the problem that if the removed petri dish lids are placed randomly next to the settling dish or in other locations, the inner side of the lid may come into contact with non-sterile surfaces, introducing contamination and posing potential quality and safety hazards to the production process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a settling dish structure for deployment in a Class A clean area, including a support body, a clamping assembly, and a settling dish body; The clamping assembly is disposed at the lower end of the support body and is used to fix the support body; The sedimentation dish body includes a support plate, which is horizontally arranged and fixed to the upper end of the support body. The upper surface of the support plate is provided with a first area and a second area. The first area is used to place the culture dish, and the second area is used to place the culture dish lid.

[0006] In one possible implementation, the first region has a limiting groove for accommodating a petri dish with its opening facing upward and restricting its horizontal displacement, and the second region has a limiting boss for inserting a petri dish lid with its opening facing downward and restricting its horizontal displacement.

[0007] In one possible implementation, the first region and the second region are arranged at intervals along the length of the settling dish body.

[0008] In one possible implementation, the upper end face of the settling disc body is provided with a retaining edge in the circumferential direction, the height of the retaining edge increases from the first region to the second region, and the retaining edge is inclined outward from bottom to top.

[0009] In one possible implementation, the settling dish body has a plurality of longitudinal through holes, which are located in the first region and the second region, respectively.

[0010] In one possible implementation, the support body includes a housing, a lifting rod, a transmission assembly, and a drive component. The housing is fixed to the upper end of the clamping assembly. The lifting rod is longitudinally disposed inside the housing, with its upper end extending out of the housing and connected to the lower end of the settling disc body. The drive component is disposed on one side of the housing. The transmission assembly is disposed inside the housing and transmits power to the lifting rod and the drive component, respectively. The drive component drives the lifting rod to rise and fall through the transmission assembly.

[0011] In one possible implementation, the transmission assembly includes a first gear, a second gear, and a toothed plate segment. The first gear is connected to one end of the drive member that extends into the housing. The second gear is disposed on the inner wall of the housing and meshes with the first gear. The toothed plate segment is located in the middle of the lifting rod and meshes with the second gear for transmission.

[0012] In one possible implementation, the driving component includes a drive shaft that is laterally rotatably mounted on the side wall of the housing. A drive handwheel is provided at one end of the drive shaft located outside the housing, and the first gear is mounted at one end of the drive shaft that passes through the housing.

[0013] In one possible implementation, a guide sleeve is provided at the bottom of the inner cavity of the housing, and the lower end of the lifting rod is slidably disposed within the guide sleeve.

[0014] In one possible implementation, the clamping assembly includes a fixed clamping plate and a movable clamping plate. The fixed clamping plate is horizontally fixed to the lower end of the support body, and a threaded rod is vertically arranged on the lower end face of the fixed clamping plate. The movable clamping plate is horizontally arranged below the fixed clamping plate and is movably sleeved on the threaded rod. An adjusting sleeve is threaded onto the threaded rod, and the adjusting sleeve is located below the movable clamping plate and abuts against the lower end face of the movable clamping plate.

[0015] The beneficial effects of the sedimentation dish structure for deployment in Class A clean areas provided by this utility model are as follows: Compared with the prior art, by setting a clamping component at the lower end of the support body, the sedimentation dish can be stably deployed in the clean area, resisting external interference and avoiding the risk of contamination of the petri dishes and lids due to tipping. As for the sedimentation dish body, the support plate is horizontally fixed to the upper end of the support body, constructing a stable bearing plane, and its upper surface is divided into a first area and a second area. The first area is used to place the petri dishes, and the second area is specifically used to store the petri dish lids. This partitioned design meets the requirements of aseptic operation procedures, allowing operators to place the lids in an independent and fixed second area when opening the petri dishes for microbial sampling, avoiding contact with non-sterile external surfaces, thereby effectively avoiding the risk of contamination.

[0016] This invention provides a sedimentation dish structure for deployment in Class A clean areas. By placing the petri dishes and lids in separate zones, it eliminates the risk of contamination from haphazard lid placement, prevents the adhesion of impurities and microorganisms, and greatly reduces the possibility of secondary contamination. This strengthens the defense for clean area environmental safety and reduces quality and safety risks in the production process. With the risk of lid contamination reduced, microbial samples collected from the petri dishes accurately reflect the actual sedimentation status of the clean area, avoiding interference from external contamination on monitoring data and ensuring the reliability of monitoring results.

[0023] Please see Figures 1 to 3 The present invention provides a settling dish structure for deployment in a Class A clean area. The settling dish structure includes a support body, a clamping assembly, and a settling dish body 1. The clamping assembly is located at the lower end of the support body and is used to fix the support body. The settling dish body 1 includes a support plate, which is horizontally positioned and fixed to the upper end of the support body. The upper surface of the support plate has a first region and a second region. The first region is used to place a petri dish, and the second region is used to place a petri dish lid.

[0024] The sedimentation dish structure provided by this utility model for deployment in Class A clean areas, compared with the prior art, ensures stable deployment of the sedimentation dish within the clean area by setting a clamping component at the lower end of the supporting body, resisting external interference and avoiding the risk of contamination of the petri dishes and lids due to tipping. The sedimentation dish body 1 has a support plate horizontally fixed to the upper end of the supporting body, constructing a stable bearing plane, and its upper surface is divided into a first area and a second area. The first area is used to place the petri dishes, and the second area is specifically used to store the petri dish lids. This partitioned design meets the requirements of aseptic operation procedures, allowing operators to place the lids in an independent, fixed second area when opening the petri dishes for microbial sampling, avoiding contact with non-sterile external surfaces, thereby effectively avoiding the risk of contamination.

[0025] This invention provides a sedimentation dish structure for deployment in Class A clean areas. By placing the petri dishes and lids in separate zones, it eliminates the risk of contamination from haphazard lid placement, prevents the adhesion of impurities and microorganisms, and greatly reduces the possibility of secondary contamination. This strengthens the defense for clean area environmental safety and reduces quality and safety risks in the production process. With the risk of lid contamination reduced, microbial samples collected from the petri dishes accurately reflect the actual sedimentation status of the clean area, avoiding interference from external contamination on monitoring data and ensuring the reliability of monitoring results.

[0026] Please see Figure 3 and Figure 4 The first region has a limiting groove 2, which is used to accommodate a petri dish with its opening facing upwards and restrict its horizontal displacement. The second region has a limiting boss 3, which is used to insert into the lid of a petri dish with its opening facing downwards and restrict its horizontal displacement. The limiting groove 2 and the limiting boss 3 effectively restrict the horizontal displacement of the petri dish and the lid by tightly fitting against the outer wall of the petri dish and inserting into the inner side of the lid, respectively. This makes the placement and retrieval of the petri dish and lid more standardized, greatly reduces the risk of shaking and misalignment caused by improper operation, and significantly improves the standardization and efficiency of monitoring operations.

[0027] This limiting design eliminates the possibility of the petri dish and lid moving freely and coming into contact with non-sterile surfaces. It not only prevents the culture medium from spilling out and contaminating the clean area, but also keeps the inside of the lid completely isolated from the outside environment, preventing dust and microorganisms from adhering, significantly reducing the risk of secondary contamination and ensuring the cleanliness of the clean area environment and the purity of the monitored samples. Furthermore, the limiting structure can be customized to accommodate various consumable sizes, while reducing friction and collision wear, extending the lifespan of the settling dish and petri dish, and effectively saving monitoring costs.

[0028] Specifically, the settling dish body 1 adopts a rectangular plate combined with rounded ends, with the first and second areas for placing the petri dishes and lids spaced apart along the length. The rectangular plate structure provides a regular and stable bearing surface for the petri dishes and lids, facilitating standardized production and processing. The rounded ends avoid the sharp corners of traditional right-angle designs, preventing accidental scraping and injury to operators in confined clean areas and reducing the risk of debris contamination from collisions. The spaced arrangement of the first and second areas conforms to the operator's usage habits, making the placement and retrieval of petri dishes and lids smoother and more natural, reducing operational errors caused by large hand movements. The reasonable spacing design also effectively avoids mutual interference between the two areas, further isolating the risk of cross-contamination.

[0029] Please see Figure 3 and Figure 4 The upper surface of the sedimentation dish body 1 is provided with a circumferential baffle 4. The height of the baffle 4 increases from the first region to the second region, and the baffle 4 slopes outward from bottom to top. The baffle 4 surrounds the sedimentation dish body 1 to form a secondary protective barrier. Even if it is accidentally bumped or slightly vibrated during operation, it can effectively prevent the culture dish and lid from sliding outward, avoiding the risk of monitoring interruption and clean area contamination caused by sample falling, and providing reliable safety for monitoring work.

[0030] The structural design of the baffle 4, with its height increasing from the first area to the second area, fully considers monitoring needs and the characteristics of the petri dishes. In the first area where the petri dishes are placed, the lower baffle 4 height ensures that there is no excessive obstruction above the opening of the petri dish, allowing air to freely enter the petri dish. This ensures that the microbial settling process is not hindered, guaranteeing that the monitoring data accurately reflects the natural settling of microorganisms in the clean area and improving the effectiveness of the monitoring results.

[0031] The design of the edge 4, which slopes outward from bottom to top, further optimizes the user experience and cleaning / maintenance process. The sloping structure creates an expanded guiding space, allowing operators to more easily reach and remove their hands when placing or removing petri dishes and lids, reducing the risk of collisions due to limited space and significantly improving operational efficiency. Simultaneously, this angle creates an obtuse angle at the junction of the edge 4 and the settling dish body 1. Compared to right or acute angles, obtuse angles are less prone to dust, stains, and disinfectant residue, allowing cleaning tools to easily reach every corner, greatly reducing cleaning dead zones. This meets the stringent cleanliness requirements of Class A cleanrooms, ensuring the settling dish remains clean even after multiple uses, continuously providing reliable support for monitoring work.

[0032] Please see Figure 3The sedimentation dish body 1 has several longitudinal through holes 5, located in a first region and a second region respectively. The longitudinal through holes 5 in the first region effectively enhance airflow when the petri dish is placed. During microbial sedimentation monitoring, the through holes promote air convection inside and outside the petri dish, preventing localized microbial aggregation or uneven sedimentation due to air stagnation, ensuring more uniform adhesion of microorganisms to the culture medium surface, thereby improving the accuracy and representativeness of the monitoring data. The longitudinal through holes 5 in the second region focus on the cleaning and drying of the petri dish lid. Before and after monitoring, when the lid is placed in the second region, the through holes accelerate the evaporation of residual moisture and disinfectant, preventing bacterial growth from moisture and disinfectant contamination of the lid, while also facilitating the removal of impurities by cleaning tools, continuously maintaining the cleanliness of the lid.

[0033] In microbial monitoring in Class A clean areas, to meet the monitoring needs of different heights and scenarios, the supporting structure of the settling dish adopts a combined structure design of a housing 6, a lifting rod 10, a transmission component, and a drive unit. The housing 6 serves as the core base, mounted on top of the clamping assembly, providing solid and stable support for the entire system. The lifting rod 10, extending longitudinally into the housing 6, connects at its upper end to the lower end of the settling dish body 1, serving as the connecting component for height adjustment. The drive unit is located on one side of the housing 6, acting as the power source. The transmission component within the housing 6 transmits the power from the drive unit to the lifting rod 10, enabling flexible vertical raising and lowering of the settling dish body 1. Operators can adjust the height of the settling dish body 1 through the cooperation of the drive unit and the transmission component, ensuring the culture dish is in the optimal monitoring position, effectively eliminating monitoring blind spots, and improving the completeness and accuracy of monitoring. The enclosed design of the drive unit and transmission component effectively isolates the clean area from dust and impurities, extending the equipment's service life and reducing maintenance costs.

[0034] Specifically, the enclosure 6 is a rectangular box with an inspection door 7 on its front side. The inspection door 7 is connected to the main body of the enclosure 6 via hinges or snap-fit ​​mechanisms, allowing for flexible opening and closing and providing a convenient access point for the inspection and maintenance of the internal components. A pre-drilled hole is provided at the top of the enclosure 6, into which a sealing sleeve 9 is embedded. The lifting rod 10 passes through the hollow of the sealing sleeve 9 and slides in a sealing fit. The size of the pre-drilled hole matches the sealing sleeve 9, ensuring a tight fit between the sleeve and the upper surface of the enclosure 6 after insertion. The sealing sleeve 9 is typically made of wear-resistant, highly elastic sealing material (such as fluororubber, polytetrafluoroethylene, etc.), and its inner wall has an annular sealing groove or lip structure. When the lifting rod 10 passes through the sleeve, it forms a dynamic seal with the outer wall of the lifting rod 10 through elastic deformation, allowing the lifting rod 10 to slide freely while effectively preventing external contaminants from entering the enclosure 6.

[0035] In addition, a rotating platform 8 is provided at the upper end of the lifting rod 10, and a mounting recess adapted to the rotating platform 8 is provided on the lower end face of the settling disc body 1. The upper end of the rotating platform 8 is embedded in the mounting recess and glued and fixed. A rotating sleeve is provided in the middle of the lower end face of the rotating platform 8. The upper end of the lifting rod 10 passes through the rotating sleeve and, with the help of bearings, enables the rotating platform 8 to drive the settling disc body 1 to rotate horizontally. When it is necessary to adjust the monitoring angle of the settling disc, the operator only needs to manually rotate the settling disc body 1, which will drive the rotating platform 8 to achieve flexible horizontal rotation adjustment with the support of the bearings.

[0036] Please see Figure 2 The transmission assembly employs a combination structure of a first gear 14, a second gear 15, and a toothed plate segment 11 to achieve efficient power transmission from the drive component to the lifting rod 10. One end of the drive component, penetrating the housing 6, is connected to the first gear 14 as a power source. The first gear 14 meshes with the second gear 15, which is rotatably mounted on the inner wall of the housing 6 via a central shaft, completing the direction conversion and transmission of the drive component's rotational motion. The toothed plate segment 11, located in the middle of the lifting rod 10, then meshes with the second gear 15, converting the rotational motion into the linear lifting motion of the lifting rod 10. The meshing between gears and between gears and the toothed plate ensures stable and accurate power transmission. The cooperation between the two gear stages and the toothed plate segment 11 forms a stable transmission chain, effectively preventing slippage and jamming, ensuring smooth lifting of the sedimentation dish, and preventing the culture dish from shaking and affecting the accuracy of monitoring data.

[0037] Preferably, the second gear 15 can be in the form of a multi-stage gear, and the first gear 14 meshes with any of the above-mentioned stage gears, thereby realizing the transmission between the first gear 14 and the second gear 15.

[0038] Please see Figure 2 The drive unit employs a combination design of drive shaft 13 and drive handwheel 16, working in conjunction with the transmission assembly to achieve height adjustment of the settling disc body 1. Drive shaft 13 is horizontally rotatably mounted on the side wall of housing 6. The drive handwheel 16, mounted on one end of the outer side of housing 6, serves as the power input, facilitating operator control. A first gear 14, fixed at one end inside housing 6, meshes with a second gear 15 in the transmission assembly, transmitting the rotational power of drive shaft 13 to lifting rod 10. When the operator rotates drive handwheel 16, drive shaft 13 rotates accordingly, driving first gear 14 to rotate. Through the transmission of second gear 15 and gear plate segment 11, the lifting rod 10 is raised and lowered linearly, completing the height adjustment of the settling disc body 1. Drive handwheel 16 allows operators to easily adjust the height of the settling disc without tools, significantly reducing labor intensity and improving monitoring efficiency in the context of heavy, sterile equipment in Class A cleanrooms. In addition, the correspondence between the rotation angle of the drive handwheel 16 and the height of the lifting rod 10 allows operators to make precise adjustments based on experience or scale markings, ensuring that the petri dish accurately reaches the target monitoring position and guaranteeing data reliability.

[0039] Please see Figure 2 A guide sleeve 12 is added to the bottom of the inner cavity of the housing 6, and the lower end of the lifting rod 10 is slidably set in the guide sleeve 12. The guide sleeve 12 is vertically fixed to the bottom of the housing 6, and its inner wall is slidably engaged with the outer wall of the lifting rod 10. When the driving component and the transmission component work together to drive the lifting rod 10 to make linear movements, the guide sleeve 12 strictly limits the horizontal offset and sway of the lifting rod 10 through the constraint of its inner wall, ensuring that the lifting rod 10 only moves vertically along the axial direction, so that the settling disc body 1 always remains stable and accurate during height adjustment.

[0040] Please see Figure 1 and Figure 2 The clamping assembly includes a fixed clamping plate 17 and a movable clamping plate 18. The fixed clamping plate 17 is horizontally fixed to the lower end of the support body, serving as a basic support. A threaded rod 19 is vertically arranged on its lower end face, providing guidance and support for the movement of the movable clamping plate 18. The movable clamping plate 18 is fitted onto the threaded rod 19 and can slide freely along the rod. An adjusting sleeve 20 located below it is threadedly connected to the threaded rod 19, becoming the driving component for adjustment. When the operator rotates the adjusting sleeve 20, the adjusting sleeve 20 moves axially along the threaded rod 19, pushing the movable clamping plate 18 closer to or away from the fixed clamping plate 17, thereby changing the distance between the two clamping plates and achieving clamping or loosening of worktable surfaces of different thicknesses.

[0041] Operators can quickly install and remove the settling disc on the workbench using only the rotating adjusting sleeve 20, without any additional tools. This significantly improves monitoring preparation efficiency and meets the needs of clean areas where monitoring points are frequently changed. The threaded drive provides axial force to the adjusting sleeve 20, ensuring that the movable clamping plate 18 and the fixed clamping plate 17 clamp the workbench evenly and tightly, preventing displacement or shaking of the settling disc during monitoring and ensuring accurate and reliable monitoring data.

[0042] Preferably, the fixed clamping plate 17 and the movable clamping plate 18 are respectively provided with slidingly fitted guide sleeves 22 and guide posts 21 on opposite sides. The guide posts 21 are vertically fixed on the fixed clamping plate 17, and the guide sleeves 22 are correspondingly provided on the movable clamping plate 18. The two slide together to form a guiding structure. When the adjusting sleeve 20 drives the movable clamping plate 18 to move up and down along the threaded rod 19, the guide posts 21 slide within the guide sleeves 22, which not only provides precise guidance for the movement of the movable clamping plate 18, but also effectively distributes the lateral force, ensuring that the movable clamping plate 18 is always horizontal and moves parallel to the fixed clamping plate 17, and preventing tilting and jamming caused by uneven force.

[0043] Preferably, an elastic layer is bonded to both the fixed clamping plate 17 and the movable clamping plate 18 on opposite sides. The elastic layer is generally made of materials with both high elasticity and wear resistance, such as silicone or rubber, and is firmly attached to the surface of the clamping plate with the help of adhesive. When the adjusting sleeve 20 drives the movable clamping plate 18 close to the fixed clamping plate 17 to clamp the worktable, the elastic layer will undergo elastic deformation, closely conforming to the slight unevenness of the worktable. This not only increases the friction between the clamping plate and the worktable, but also fills the gaps caused by uneven surfaces, achieving a more stable clamping effect.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
