Description

Technical Field

[0001] This utility model relates to the field of high-efficiency air outlet technology, and in particular to a high-efficiency air outlet for cleanrooms with an easy-to-disassemble diffuser plate. Background Technology

[0002] Cleanrooms utilize specialized internal environmental control systems to precisely regulate parameters such as particulate concentration, temperature, humidity, and airflow, creating an extremely clean space with minimal particulate matter. This is essential for industries with stringent environmental requirements, such as chip manufacturing and pharmaceutical production. Therefore, personnel entering cleanrooms must wear multiple layers of cleanroom suits (e.g., triple-layered gowns), along with appropriate cleanroom hoods, goggles, masks, and multiple layers of gloves to ensure no contamination is caused.

[0003] After each production cycle, cleanrooms require cleaning and disinfection. Disinfectants used for cleanroom cleaning (such as hydrogen peroxide, ozone, and sporicides) are typically corrosive; therefore, the diffusers on cleanroom ceilings are usually made of corrosion-resistant stainless steel, resulting in a significant weight. According to regulations, cleanrooms of Class A and B require verification every six months, while Class C and D require verification annually. Therefore, most diffusers in cleanrooms are disassembled and reassembled every six months, and all diffusers in a cleanroom are completely disassembled and reassembled annually.

[0004] However, the current process of disassembling and assembling diffusers has at least the following drawbacks:

[0005] First, when it is necessary to disassemble or assemble the diffuser, the diffuser is quite heavy, and the traditional way to install the diffuser is usually by bolts. Therefore, when disassembling or assembling the diffuser on the cleanroom ceiling, one worker needs to hold up the diffuser while another worker disassembles or assembles it. It is not possible for one person to disassemble or assemble the diffuser, which greatly increases labor costs.

[0006] Secondly, using bolts to install the diffuser is very inconvenient and has very low disassembly and assembly efficiency. At the same time, the bolts are also very prone to damage, stripping, or loss during long-term use, which further reduces the disassembly and assembly efficiency.

[0007] Finally, because workers need to wear multiple layers of cleanroom suits (e.g., three times a night) after entering the cleanroom, and the method of installing diffusers with bolts is inherently inefficient, workers are forced to work at heights in a three-night environment for extended periods, leading to physical exhaustion and potentially causing safety accidents. Furthermore, installing diffusers with bolts exposes workers to the stuffy, hot environment inside the cleanroom suits for extended periods, increasing the risk of oxygen deficiency and further raising the risk of accidents.

[0008] Therefore, how to reduce the labor costs of disassembling and assembling diffusers, improve the efficiency of disassembly and assembly, reduce the risk of safety accidents, and thus ensure the personal safety of workers has become an urgent problem to be solved. Utility Model Content

[0061] For those skilled in the art, this invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples.

[0062] Reference Figures 1-13 This utility model provides a high-efficiency air outlet for cleanrooms with an easily detachable diffuser plate, comprising at least a high-efficiency air outlet static pressure box body 1, a static pressure box flange 2, and a diffuser plate body 3, wherein:

[0063] like Figure 5 As shown, the static pressure box flange 2 is installed at the outlet of the high-efficiency air supply static pressure box body 1 (i.e., Figure 5 (Bottom of the static pressure box body 1 for medium and high efficiency air outlet).

[0064] In this embodiment, as Figure 5 As shown, the high-efficiency air outlet static pressure box body 1 can be a cuboid structure or a roughly cuboid structure, while the static pressure box flange 2 can be a square ring structure or a roughly square ring structure adapted to the bottom end of the high-efficiency air outlet static pressure box body 1, thereby being installed at the edge of the air outlet of the high-efficiency air outlet static pressure box body 1. The static pressure box flange 2 can be connected to the high-efficiency air outlet static pressure box body 1 by means such as welding (known in the art), and no particular limitation is made here.

[0065] In this embodiment, as Figure 3 and Figure 6 As shown, the diffuser body 3 can be a square structure or a roughly square structure that is adapted to the static pressure box flange 2.

[0066] like Figures 1-3 As shown, at least two opposing temporary fixing mechanisms are installed on the diffuser body 3. The temporary fixing mechanisms are configured to be detachably connected to the static pressure box flange 2, so that the diffuser body 3 can be temporarily installed at the bottom of the high-efficiency air outlet static pressure box body 1.

[0067] In this embodiment, as Figure 3 As shown, the number of temporary fixing mechanisms can preferably be two. More preferably, both temporary fixing mechanisms can be located on the central axis of the diffuser body 3.

[0068] like Figure 3 , Figure 4 and Figure 6 As shown, at least two opposing long-term locking mechanisms are also installed on the diffuser body 3, and the long-term locking mechanism is adjacent to the temporary fixing mechanism. The long-term locking mechanism is configured to be detachably connected to the high-efficiency air outlet static pressure box body 1, so that the diffuser body 3 can be permanently installed at the bottom of the high-efficiency air outlet static pressure box body 1.

[0069] In this embodiment, as Figure 3 As shown, the number of long-term locking mechanisms can preferably be two. More preferably, both long-term locking mechanisms can be located on the central axis of the diffuser body 3, that is, the line connecting the two long-term locking mechanisms and the line connecting the two temporary fixing mechanisms will roughly form a cross shape.

[0070] Specifically, in this embodiment, such as Figure 2 , Figure 9 , Figure 10 and Figure 12 As shown, the temporary fixing mechanism includes at least a first external threaded sleeve 5 installed on the diffuser body 3.

[0071] In this embodiment, as Figure 9 As shown, a first nut 11 can be threadedly connected to the first external threaded sleeve 5. The first nut 11 is configured such that its bottom end can abut against the top end of the diffuser body 3 (not shown in the figure), thereby realizing the detachable connection between the first external threaded sleeve 5 and the diffuser body 3.

[0072] In this embodiment, as Figure 9 As shown, the outer contour of the first external threaded sleeve 5 can be or approximately the same as the structure of bolts known in the art. Therefore, the bolt head of the first external threaded sleeve 5 and the first nut 11 can clamp the two ends of the diffuser body 3, thereby realizing the detachable connection between the first external threaded sleeve 5 and the diffuser body 3.

[0073] More specifically, in this embodiment, as Figure 10 and Figure 12 As shown, the temporary fixing mechanism also includes a movable rod 7 that is slidably installed within the first external threaded sleeve 5, preferably the movable rod 7 being arranged parallel to the first external threaded sleeve 5. A spring 8 is fitted onto the movable rod 7, with both ends of the spring 8 connected to the first external threaded sleeve 5 and the movable rod 7, respectively.

[0074] In this embodiment, as Figure 10 As shown, a partition plate can be fixedly installed horizontally inside the first external threaded sleeve 5. This partition plate divides the interior of the first external threaded sleeve 5 into upper and lower chambers. The moving rod 7 can pass through the partition plate and slide in cooperation with it, thereby achieving a limited sliding connection of the moving rod 7 inside the first external threaded sleeve 5. The spring 8 can be located in the chamber below the partition plate. The top end of the spring 8 can be fixedly connected to the bottom end of the partition plate, and the bottom end of the spring 8 can be fixedly connected to the side wall of the moving rod 7.

[0075] In this embodiment, the fixed connection method between the spring 8 and the partition plate, and between the spring 8 and the side wall of the moving rod 7, is not particularly limited. Both can be connected by means such as bolts (known in the art).

[0076] like Figures 9-11 As shown, a locking tongue 9 is hinged to the inner wall of the first external threaded sleeve 5. A transmission rod 10 is installed on the locking tongue 9. The top end of the moving rod 7 is in transmission cooperation with the transmission rod 10 so that the locking tongue 9 can be inserted into or extended out of the interior of the first external threaded sleeve 5 as a whole. That is, the locking tongue 9 can be inserted into the interior of the first external threaded sleeve 5 as a whole, or it can be extended out of the exterior of the first external threaded sleeve 5 as a whole.

[0077] In this embodiment, as Figure 10 and Figure 11 As shown, there can be two locking tongues 9, and the two locking tongues 9 are arranged opposite each other. Preferably, the locking tongue 9 has a right-angled triangular structure. When the locking tongue 9 extends entirely out of the interior of the first external threaded sleeve 5 (i.e....), Figure 10 In the state shown, that is, when the locking tongue 9 extends out of the first external threaded sleeve 5, its hypotenuse can be located outside the first external threaded sleeve 5, and at this time its lower right-angled side is set in a horizontal direction.

[0078] In this embodiment, as Figure 10 As shown, the transmission rod 10 can be installed... Figure 10 On the right-angled side in the vertical direction, the end furthest from the locking tongue 9 contacts the top of the moving rod 7. When the moving rod 7 moves upward, its top pushes the transmission rod 10 upward, thereby allowing the locking tongue 9 to extend into the interior of the first external threaded sleeve 5 (see reference). Figure 12 ).

[0079] It should be understood that, such as Figure 12 As shown, when the moving rod 7 moves upward, that is, when it pushes the transmission rod 10 upward, Figure 12 The transmission rods 10 located on the left and right sides do not come into contact with each other during the upward movement of the moving rod 7, thus ensuring that the locking tongue 9 can smoothly extend into the interior of the first external threaded sleeve 5. Meanwhile, as... Figure 12 As shown, Figure 12 The width of the upper half of the moving rod 7 in the middle can be less than Figure 12 The width of the lower half of the moving rod 7 is such that when the locking tongue 9 is fully inserted into the interior of the first external threaded sleeve 5, the locking tongue 9 will not come into contact with the side wall of the moving rod 7, thereby ensuring that the locking tongue 9 can be smoothly inserted into the interior of the first external threaded sleeve 5.

[0080] like Figure 11 As shown, a torsion spring 12 is installed at the hinge point (i.e., on the hinge) between the locking tongue 9 and the first external threaded sleeve 5. The two ends of the torsion spring 12 are connected to the locking tongue 9 and the first external threaded sleeve 5, respectively. When the locking tongue 9 extends entirely outside the first external threaded sleeve 5 (i.e....), Figure 10 When the torsion spring 12 is in the state of being inserted into the first external threaded sleeve 5, it will not have elastic potential energy. Figure 12 When in the state of being in motion, the torsion spring 12 will have a certain elastic potential energy.

[0081] like Figure 10 As shown, a moving rod limiting block is fixedly installed on the side wall of the moving rod 7. When the moving rod 7 is in the position... Figure 10 When in the middle state, the bottom end of the moving rod limiting block will abut against the top end of the aforementioned partition plate, thereby limiting the moving rod 7 and preventing the moving rod 7 from moving. Figure 10 It continues to move downwards from the middle state, thereby preventing the transmission rod 10 from disengaging from the top of the moving rod 7.

[0082] like Figure 2 As shown, when the locking tongue 9 extends entirely out of the interior of the first external threaded sleeve 5, the bottom end of the locking tongue 9 (i.e. Figure 10 The middle locking tongue 9 (with a right-angled side in the horizontal direction) is designed to abut against the top of the static pressure box flange 2, so as to realize the detachable connection between the diffuser plate body 3 and the static pressure box flange 2.

[0083] Furthermore, such as Figure 2 and Figure 5 As shown, a gasket 4 is installed at the top of the static pressure box flange 2, and the gasket 4 is correspondingly set with the first external threaded sleeve 5; when the locking tongue 9 extends entirely out of the interior of the first external threaded sleeve 5 (that is, when the locking tongue 9 extends entirely to the exterior of the first external threaded sleeve 5), the bottom end of the locking tongue 9 (i.e. Figure 10 The locking tongue 9 (with a right-angled side in the horizontal direction) is designed to abut against the top of the gasket 4 to achieve a detachable connection between the diffuser body 3 and the static pressure box flange 2. The gasket 4 can be a flat cuboid structure.

[0084] In this embodiment, the installation of the gasket 4 can improve the structural strength of the contact point between the locking tongue 9 and the static pressure box flange 2, thereby preventing the static pressure box flange 2 from being dented by the locking tongue 9.

[0085] Furthermore, such as Figure 3 , Figure 9 , Figure 10 and Figure 12 As shown, a button 6 is installed at the bottom end of the moving rod 7. The button 6 is located inside the first external threaded sleeve 5, and the side wall of the button 6 slides in contact with the inner wall of the first external threaded sleeve 5. Wherein, as... Figure 10 As shown, when the locking tongue 9 extends out of the interior of the first external threaded sleeve 5 (i.e. Figure 10 When in the middle state), the bottom end of button 6 is preferably flush with the bottom end of the first external threaded sleeve 5.

[0086] In this embodiment, the button 6 allows for easier pressing of the moving rod 7. Furthermore, the bottom of the button 6 is flush with the bottom of the first external threaded sleeve 5, ensuring a smooth surface and meeting the cleanroom equipment surface disinfection requirements.

[0087] Specifically, in this embodiment, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 13 As shown, the long-term locking mechanism includes at least a second external threaded sleeve 13 installed on the diffuser body 3.

[0088] In this embodiment, as Figure 7 As shown, a second nut 16 can be threadedly connected to the second external threaded sleeve 13. The second nut 16 is configured to abut against the top end of the diffuser body 3 to achieve a detachable connection between the second external threaded sleeve 13 and the diffuser body 3.

[0089] In this embodiment, as Figure 7 and Figure 13 As shown, the outer contour of the second external threaded sleeve 13 can be or approximately the same as the structure of bolts known in the art. Therefore, the bolt head of the second external threaded sleeve 13 and the second nut 16 can clamp the two ends of the diffuser body 3, thereby realizing the detachable connection between the second external threaded sleeve 13 and the diffuser body 3.

[0090] More specifically, in this embodiment, as Figure 7 and Figure 13 As shown, the long-term locking mechanism also includes a rotating rod 14 that is rotatably installed in the second external threaded sleeve 13, preferably the rotating rod 14 is arranged parallel to the second external threaded sleeve 13.

[0091] like Figure 6 and Figure 7As shown, a limit plate 20 is installed at the top of the diffuser body 3. A locking rod 19 is slidably installed on the limit plate 20 at the upper limit. The locking rod 19 is correspondingly set with the rotating rod 14 and is in transmission cooperation with the rotating rod 14.

[0092] In this embodiment, as Figure 7 As shown, the locking rod 19 can pass through the limiting plate 20 as a whole and slide in cooperation with the limiting plate 20, thereby realizing the limiting sliding cooperation between the locking rod 19 and the limiting plate 20.

[0093] In this embodiment, as Figure 6 and Figure 7 As shown, each rotating rod 14 can have two locking rods 19 that are engaged in transmission. The two locking rods 19 are arranged in parallel, and the ends of the two locking rods 19 that are away from the rotating rod 14 are facing opposite directions.

[0094] like Figure 1 and Figure 5 As shown, the high-efficiency air outlet static pressure box body 1 has a locking rod locking hole adapted to the locking rod 19, and the locking rod locking hole is correspondingly set with the locking rod 19. For example, Figure 1 As shown, the locking rod 19 is configured to extend into the locking hole of the locking rod by rotating the rotating rod 14, thereby realizing the detachable connection between the diffuser body 3 and the high-efficiency air outlet static pressure box body 1.

[0095] More specifically, such as Figure 7 and Figure 13 As shown, a gear 17 is provided at the top of the rotating rod 14, and the rotating rod 14 and the gear 17 are connected at the center position, preferably by means of bolt connection.

[0096] like Figure 7 As shown, a rack 18 is bolted onto the locking rod 19. The rack 18 meshes with the gear 17, thereby enabling the rotating rod 14 to engage with the locking rod 19 via the gear 17 and the rack 18.

[0097] by Figure 7 For example, when the rotating rod 14 rotates counterclockwise, the gear 17 will also rotate counterclockwise simultaneously, causing the locking rod 19 to extend into the locking rod locking hole, thereby achieving a detachable connection between the diffuser body 3 and the high-efficiency air outlet static pressure box body 1. Conversely, when the rotating rod 14 rotates clockwise, the locking rod 19 can be disengaged from the locking rod locking hole.

[0098] Furthermore, such as Figure 4 and Figure 13As shown, a knob 15 is installed at the bottom end of the rotating rod 14. The knob 15 is located inside the second external threaded sleeve 13, and the side wall of the knob 15 slides in contact with the inner wall of the second external threaded sleeve 13. The knob 15 allows the rotating rod 14 to be rotated more conveniently and effortlessly.

[0099] like Figure 4 and Figure 13 As shown, the end of the knob 15 furthest from the rotating rod 14 is provided with an internal turning mechanism. This internal turning mechanism is not particularly limited; it can be a straight line, a cross shape, or a star-shaped structure, but is preferably preferred. Figure 4 The diagram shows a flat-bottomed structure. When it is necessary to rotate the rotating rod 14, a flathead screwdriver is inserted into the flat-bottomed inner screw mechanism of the knob 15 to rotate it, which makes it easy to rotate the rotating rod 14.

[0100] In this embodiment, as Figure 7 and Figure 13 As shown, a circular rotating rod limiting rotating plate is installed on the side wall of the rotating rod 14. This rotating rod limiting rotating plate is positioned relative to the top end of the second external threaded sleeve 13 (i.e., Figure 13 The top end of the second external threaded sleeve 13 is in contact with and slides into the sleeve. At this time, the knob 15 and the rotating rod limiting rotating plate will contact and slide into the two ends of the second external threaded sleeve 13 respectively, thereby realizing the limiting rotational connection between the rotating rod 14 and the second external threaded sleeve 13.

[0101] According to one embodiment of the present invention, such as Figure 8 As shown, the locking rod 19 is slidably connected to at least two limiting plates 20, preferably two, and there is a distance between the two limiting plates 20, which is less than or equal to the length of the rack 18. A limiting block 21 is installed on the locking rod 19, and the limiting block 21 is located between the two limiting plates 20.

[0102] In this embodiment, the limiting block 21 can be a flat cuboid structure or a generally flat cuboid structure.

[0103] In this embodiment, when the locking rod 19 extends into the locking rod locking hole (i.e., when the diffuser body 3 is permanently locked to the high-efficiency air outlet static pressure box body 1 by the locking rod 19), the limiting block 21 is configured to be able to engage with the limiting plate 20 (i.e., the end away from the second external threaded sleeve 13) at the other end. Figure 8 The limiting plate 20 on the right side of the middle part ... 13, the limiting block 21 is configured to abut against the limiting plate 20 near the end of the second external thread sleeve 13 (i.e., the limiting plate Figure 8 The left side limit plate 20) abuts.

[0104] The two limiting plates 20 make it easier for workers to determine the locking status between the diffuser body 3 and the high-efficiency air outlet static pressure box body 1, thereby improving disassembly and assembly efficiency. For example, when it is necessary to remove the diffuser body 3 from the long-term lock of the high-efficiency air outlet static pressure box body 1 (i.e., when the diffuser body 3 needs to be removed), the limiting block 21 will move towards the fixed position as the knob 15 rotates. Figure 8 Move to the left in the middle until it matches Figure 8 The left-side limiting plate 20 abuts against the switch. At this point, the knob 15 will be unable to be turned, thus allowing the worker to know in a timely manner that the locking rod 19 has completely disengaged from the locking rod locking hole, thereby improving the efficiency of disassembly and assembly.

[0105] In addition, since the distance between the two limiting plates 20 is less than or equal to the length of the rack 18, the setting of the two limiting plates 20 can also prevent the gear 17 from disengaging from the rack 18, thus ensuring the normal progress of disassembly and assembly.

[0106] The following will briefly describe the assembly and disassembly process of the diffuser body 3 and the high-efficiency air outlet static pressure box body 1 in this embodiment, in conjunction with the above embodiments:

[0107] First, when it is necessary to install the diffuser body 3 on the high-efficiency air outlet static pressure box body 1, the diffuser body 3 can be directly snapped upwards onto the air outlet of the high-efficiency air outlet static pressure box body 1. At this time, the locking tongue 9 will automatically extend into the interior of the first external threaded sleeve 5 through its own bevel. When the locking tongue 9 is completely above the gasket 4, the locking tongue 9 will automatically extend out of the outside of the first external threaded sleeve 5 under the elastic potential energy stored in the torsion spring 12, so that the bottom end of the locking tongue 9 can abut against the top end of the gasket 4, realizing the temporary fixation of the diffuser body 3 and the high-efficiency air outlet static pressure box body 1. Therefore, there is no need for another worker to continuously hold up the diffuser body 3 during the installation process, which greatly reduces labor costs.

[0108] Then, by turning knob 15 with a flathead screwdriver, locking rod 19 will extend into the locking rod locking hole until limit block 21 contacts it. Figure 8 When the limiting plate on the right side stops at 20, the diffuser body 3 and the high-efficiency air outlet static pressure box body 1 can be permanently fixed, thus completely completing the installation of the diffuser body 3.

[0109] Finally, by repeating the above operations in reverse, the diffuser body 3 can be removed from the high-efficiency air outlet static pressure box body 1. Further details are omitted here.

[0110] Those skilled in the art should understand that, in the above process, when the diffuser body 3 is installed on the high-efficiency air outlet static pressure box body 1, that is, when the bottom end of the locking tongue 9 abuts against the top end of the gasket 4, there will be a certain distance between the top end of the first nut 11 and the bottom end of the static pressure box flange 2 (not shown in the figure).

[0111] When it is necessary to remove the diffuser body 3 from the static pressure box body 1 of the high-efficiency air outlet, after the locking rod 19 is completely disengaged from the locking hole, the worker can lift the diffuser body 3 upwards by using the distance between the top of the first nut 11 and the bottom of the static pressure box flange 2, raising the diffuser body 3 a certain distance until the top of the first nut 11 contacts the bottom of the static pressure box flange 2. At this time, there will be a certain distance between the bottom of the locking tongue 9 and the top of the gasket 4. When the worker presses the button 6 upwards, the locking tongue 9 can smoothly extend into the interior of the first external threaded sleeve 5, thus ensuring the normal progress of the disassembly and assembly work.

[0112] Conversely, when installing the diffuser body 3 on the static pressure box body 1 of the high-efficiency air outlet, the worker can lift the diffuser body 3 until the top of the first nut 11 contacts the bottom of the static pressure box flange 2, and then stop. This allows the locking tongue 9 to extend smoothly to the outside of the first external threaded sleeve 5. After the locking tongue 9 extends, there will be a certain distance between the bottom of the locking tongue 9 and the top of the gasket 4. At this point, the worker stops lifting the diffuser body 3, and the bottom of the locking tongue 9 will descend a certain distance and abut against the top of the gasket 4, thus completing the temporary fixation of the diffuser body 3. The length of the above-mentioned distance is not particularly limited, as long as it can smoothly ensure that the locking tongue 9 can extend into or out of the inside and outside of the first external threaded sleeve 5.

[0113] Those skilled in the art should also understand that the above embodiments or implementation schemes of this utility model can be combined with each other and have corresponding technical effects.

[0114] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
