Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, specifically a cleanroom dust prevention device. Background Technology

[0002] A cleanroom is a well-sealed space that uses special design and control technology to keep airborne particles, microorganisms, and chemical pollutants at extremely low levels to meet specific production, research, or medical needs. The environmental requirements of industries such as precision machinery and semiconductors have promoted the development of cleanroom technology.

[0003] To achieve a cleanroom's cleanliness level, comprehensive measures are necessary, including process layout, building plan, building structure, building decoration, personnel and material purification, air purification measures, and maintenance management. Among these, air purification measures are the fundamental guarantee for achieving the cleanliness level, and high-efficiency air filters are the core component of the air purification system. As the end filter in various filtration systems, their function is to filter out submicron particles smaller than 1µm, ensuring that the clean space meets the standards.

[0004] Existing high-efficiency air filters require manual lifting during installation until they are fully secured in the static pressure chamber. This method increases the time and labor intensity of manual lifting. To solve the problem of time-consuming and labor-intensive installation of high-efficiency air filters, a cleanroom dust prevention device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cleanroom dust prevention device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom dustproof device, comprising a static pressure chamber, wherein an air filter is installed inside the static pressure chamber via a locking structure for limiting the position of the air filter, the locking structure including a telescopic column installed on the outer wall of the air filter, a movable plate slidably installed on the inner wall of the static pressure chamber, one end of the movable plate abutting against the end of the telescopic column, a screw threadedly connected to the static pressure chamber, and a pressure strip rotatably connected to the end of the screw, a sliding groove provided on the inner wall of the static pressure chamber, and a pressing structure fixedly connected to the bottom of the pressure strip provided in the sliding groove, the pressing structure cooperating with the pressure strip to ensure that when the pressure strip rotates to the corresponding state, the pressing structure maintains a pressing state on the movable plate.

[0007] By adopting the above technical solution, when the user lifts the air filter into the static pressure box, the spring is first compressed and pressed against the box wall. When it reaches the through hole, the spring releases pressure, causing the telescopic column to extend into the through hole, thus fixing and restricting the position of the air filter. At this point, the user no longer needs to manually lift the air filter; they can simply rotate the pressure bar and tighten the screw to further compress the air filter, reducing the time and labor intensity of manual lifting. When disassembling the air filter, rotating the pressure bar moves the extrusion block and applies pressure to the movable plate, causing the movable plate to squeeze the telescopic column out of the through hole, thereby releasing the lock and facilitating the user's disassembly of the air filter, achieving a time-saving and labor-saving effect.

[0008] Furthermore, multiple sets of the telescopic columns are installed on the outer wall of the air filter, and the ends of the telescopic columns protrude beyond the edge of the air filter, and springs are slidably installed on the inner wall of the telescopic columns.

[0009] By adopting the above technical solution, the safety of the air filter during installation can be improved through multiple locking structures, preventing it from falling off without manual support.

[0010] Furthermore, the outer wall of the static pressure box is provided with multiple sets of through holes corresponding to the telescopic column, and the sliding groove communicates with the through holes provided on the outer wall of the static pressure box, so as to ensure that when the pressure bar rotates, the extrusion structure can smoothly abut and extrude the movable plate.

[0011] By adopting the above technical solution, the linkage between the pressure strip, the extrusion structure and the movable plate can be realized.

[0012] Furthermore, the pressure bar is rotatably connected to multiple sets on the static pressure box, and the extrusion structure includes a connecting rod fixedly installed at the bottom of the pressure bar, with an extrusion block fixedly connected to the end of the connecting rod.

[0013] By adopting the above technical solution, multiple sets of pressure strips are used to ensure that the installed air filter will not fall off or loosen, thereby improving the overall safety of the dustproof device.

[0014] Furthermore, the extrusion block has a rectangular cross-section, and the side of the extrusion block closest to the movable plate has an arc-shaped design.

[0015] By adopting the above technical solution and using the guiding nature of the curved surface design, users can more easily rotate the pressure bar to allow the extrusion block to contact the end of the movable plate and apply pressure to it, thereby achieving the effect of unlocking and realizing a more time-saving and labor-saving operation.

[0016] Furthermore, the diameter of one end of the movable plate corresponds to the diameter of the through hole opened on the outer wall of the static pressure box, and is smaller than the diameter of the other end of the movable plate.

[0017] By adopting the above technical solution, and by designing the movable plate with different diameters at both ends, the extrusion block will not come out of the through hole when extruding the movable plate, thus ensuring the integrity of the extrusion structure.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention features a locking structure that allows the user to lift the air filter into the static pressure chamber. The spring is initially compressed and pressed against the chamber wall. Once the filter reaches the through-hole, the spring releases pressure, allowing the telescopic column to extend into the through-hole. This fixes and restricts the air filter's position. At this point, the user no longer needs to manually lift the air filter; they can simply rotate the pressure bar and tighten the screw to further compress it, reducing the time and effort required for manual lifting. Furthermore, the inclusion of a compression structure allows the user to easily disassemble the air filter. Rotating the pressure bar moves the compression block, applying pressure to the movable plate, which then forces the telescopic column out of the through-hole, releasing the lock and facilitating easy disassembly. This design saves time and effort. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A cleanroom dust control device, such as Figure 1 - Figure 4 As shown, it includes a static pressure chamber 1.

[0028] Specifically, an air filter 2 is installed inside the static pressure chamber 1 via a locking structure to limit its movement. The locking structure includes a telescopic column 22 installed on the outer wall of the air filter 2, and a movable plate 21 slidably installed on the inner wall of the static pressure chamber 1. One end of the movable plate 21 abuts against the end of the telescopic column 22, so that when the telescopic column 22 enters the through hole in the wall of the static pressure chamber 1, it achieves the effect of fixing the air filter 2, eliminating the need for manual lifting of the air filter 2, thereby reducing the time and labor intensity of manual lifting. A screw 11 is threadedly connected to the static pressure chamber 1, and a pressure strip 12 is rotatably connected to the end of the screw 11. At this time, rotating the pressure strip 12 to the tightened state... The air filter 2 is further secured by tightening the screw 11. The inner wall of the static pressure box 1 has a sliding groove 14, and a pressing structure is fixedly connected to the bottom of the pressure strip 12 in the sliding groove 14. The pressing structure works in conjunction with the pressure strip 12 to ensure that when the pressure strip 12 is rotated to the corresponding state, the pressing structure keeps the movable plate 21 in a pressing state. This allows the user to rotate the pressure strip 12 to drive the pressing block 15 to move and apply pressure to the movable plate 21 when disassembling the air filter 2. This causes the movable plate 21 to squeeze the telescopic column 22 out of the through hole, thereby releasing the lock and facilitating the user to disassemble the air filter 2, achieving the effect of saving time and effort.

[0029] Please refer to Figure 1-2. Multiple sets of telescopic columns 22 are installed on the outer wall of the air filter 2. The multiple sets of locking structures can improve the safety of the air filter 2 during installation and prevent it from falling off without manual support. The ends of the telescopic columns 22 protrude from the edge of the air filter 2, and springs 23 are slidably installed on the inner wall of the telescopic columns 22. The elasticity of the springs 23 can be used to allow the telescopic columns 22 to shorten to enter the through hole and then extend when they come into contact with the wall of the static pressure box 1, which enhances the flexibility of the locking structure.

[0030] Please refer to Figure 1-2. The outer wall of the static pressure box 1 has multiple sets of through holes corresponding to the telescopic column 22, and the sliding groove 14 communicates with the through holes on the outer wall of the static pressure box 1, thereby realizing the linkage between the pressure bar 12, the extrusion structure and the movable plate 21. This is to ensure that when the pressure bar 12 rotates, the extrusion structure can smoothly abut against and extrude the movable plate 21.

[0031] Please refer to Figure 1-2. Multiple sets of pressure strips 12 are rotatably connected on the static pressure box 1. The multiple sets of pressure strips 12 ensure that the installed air filter 2 will not fall off or loosen, thereby improving the overall safety of the dustproof device. The extrusion structure includes a connecting rod 13 fixedly installed at the bottom of the pressure strip 12, and an extrusion block 15 is fixedly connected to the end of the connecting rod 13. The extrusion block 15 is driven to move by the connecting rod 13 at the bottom of the pressure strip 12 to apply pressure to the movable plate 21.

[0032] Please refer to Figure 1-1. The extrusion block 15 has a rectangular cross-section, and the side of the extrusion block 15 closest to the movable plate 21 has an arc-shaped design. The guiding nature of the arc-shaped design allows the user to more easily rotate the pressure bar 12 to bring the extrusion block 15 into contact with the end of the movable plate 21 and apply pressure to it, thereby achieving the effect of unlocking and realizing a more time-saving and labor-saving operation.

[0033] Please refer to Figure 1-2. The diameter of one end of the movable plate 21 corresponds to the diameter of the through hole opened on the outer wall of the static pressure box 1, so that the extrusion block 15 can enter the through hole when applying pressure to the movable plate 21, avoiding the situation where there is an obstacle blocking the extrusion block 15 from extruding. The diameter of the other end of the movable plate 21 is smaller than that of the other end of the movable plate 21. By designing the movable plate 21 with different diameters at both ends, the extrusion block 15 will not come out of the through hole when extruding the movable plate 21, thus ensuring the integrity of the extrusion structure.

[0034] The working principle of this utility model is as follows: When installing the air filter 2, the user needs to lift the air filter 2 into the static pressure box 1 in the correct direction. During the process of the air filter 2 entering the static pressure box 1, the spring 23 inside the telescopic column 22 is gradually compressed, and the oblique angle of the end of the telescopic column 22 enters the box along the edge of the static pressure box 1. At this time, the end of the telescopic column 22 is attached to the box wall of the static pressure box 1. When the telescopic column 22 moves to the through hole of the static pressure box 1, the spring 23 loses pressure restriction and returns to the initial state, so that the telescopic column 22 extends into the through hole, fixing and restricting the position of the air filter 2. After ensuring that multiple locking mechanisms have completed locking, the user does not need to continue lifting the air filter 2, reducing the time and labor intensity of manual lifting. Then, the pressure strip 12 is rotated to the pressing state, and the screw 11 is tightened to complete the installation of the air filter 2.

[0035] When the user needs to disassemble the air filter 2, first loosen the screw 11 to make the pressure bar 12 rotate to the compression state. During this process, the pressure bar 12 drives the compression structure to slide in the slide groove 14 until the arc end of the compression block 15 contacts the movable plate 21 and applies pressure to it. As a result, the movable plate 21 squeezes the end of the telescopic column 22, thereby causing the spring 23 to be shortened by force. At this time, the plane at the end of the telescopic column 22 is consistent with the plane at the wall of the static pressure box 1, thus achieving the function of unlocking. The user can then disassemble the air filter 2.
