Description

Technical Field

[0001] This utility model relates to the field of cleanroom purification and ventilation technology, specifically a cleanroom purification and ventilation device that facilitates filter replacement. Background Technology

[0002] A cleanroom is a dedicated space that uses engineering techniques to strictly control environmental parameters such as airborne particles, microorganisms, temperature, humidity, pressure, airflow distribution, noise, vibration, and lighting in order to meet the high cleanliness requirements of specific industrial production or scientific experiments.

[0003] When replacing filters inside cleanroom ventilation ducts, it is usually necessary to unscrew multiple screws, remove pressure strips, or loosen clips. A single replacement may take tens of minutes, which seriously affects the normal operation of the cleanroom. This is especially true in continuous production scenarios such as pharmaceuticals and semiconductors, leading to production capacity loss. The complex disassembly process can easily cause maintenance delays or omissions, resulting in filters exceeding their service life, reducing filtration efficiency, and affecting the cleanliness level.

[0004] Therefore, this utility model provides a cleanroom purification and ventilation device that facilitates filter replacement, in order to solve the above-mentioned problems. Utility Model Content

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

[0016] This utility model provides a cleanroom purification and ventilation device with an easy-to-replace filter, such as... Figures 1-6 As shown, a cleanroom purification and ventilation device that facilitates filter replacement includes a ventilation duct 1. A groove is provided on the front of the ventilation duct 1, and a magnetic suction mechanism is hinged to the edge of the groove via a hinge. Connecting plates 2 are fixedly connected to both sides of the ventilation duct 1, and a pushing mechanism is fixedly connected to the outer surface of the connecting plates 2. The magnetic suction mechanism includes a magnetic suction plate 3. The outer surface of the magnetic suction plate 3 is magnetically attracted to the inside of the groove on the front of the ventilation duct 1. A square groove for installing a visible panel 4 is opened in the middle of the magnetic suction plate 3. A magnetic block 5 is fixedly connected to the surface of the magnetic suction plate 3. A magnetic strip 6 is fixedly connected to the inner side wall of the ventilation duct 1. The magnetic strip 6 is magnetically attracted to the magnetic suction plate 3. A hole groove for installing a pushing mechanism is opened inside the visible panel 4. The magnetic suction structure can replace the traditional screw, buckle or pressure strip fixing method, making the installation and removal of the filter module a "one-click to fit, one-click to open" operation. The staff can replace the filter plate 18 in a few seconds without tools. The magnetic force is evenly distributed, avoiding local air leakage caused by uneven force in traditional mechanical fixing.

[0017] The pushing mechanism includes a miniature electric push rod 7. The outer surface of the miniature electric push rod 7 is fixedly connected to the outer surface of the connecting plate 2 via a bracket ring. One end of the miniature electric push rod 7 is fixedly connected to a pushing rod 8. One end of the pushing rod 8 is fixedly connected to a rotating block 9. The middle of the rotating block 9 is rotatably connected to a rotating component 10 via a rotating rod. One end of the rotating component 10 is fixedly connected to the outer surface of the visible panel 4. The pushing mechanism can quickly and smoothly push the magnetic plate 3 open without manually prying, rotating, or loosening multiple fasteners. The pushing mechanism provides concentrated and controllable thrust to overcome static friction and sealing resistance, reducing the burden of manual operation. During the closing process, the pushing mechanism can be reversed to act as a "pressing mechanism" to evenly press the sealing door back to its original position, ensuring that the sealing strips around the box fully fit the interface.

[0018] The pushing mechanism includes a sleeve 11, the outer surface of which is fixedly connected to the inside of the slot. One end of the sleeve 11 is fixedly connected to a base 12, and a round hole is opened in the middle of the base 12. A threaded rod 13 is threadedly connected inside the sleeve 11. A magnetic suction piece 14 is fixedly connected to one end of the threaded rod 13. A connecting frame 15 is fixedly connected to the inner wall of the ventilation duct 1. A fixing piece 16 is fixedly connected to the inner side wall of the connecting frame 15. A magnetic suction piece 17 is fixedly connected to the middle of the fixing piece 16. The threaded rod 13 is screwed into the inside of the sleeve 11. The threaded rod 13 drives the magnetic suction piece 14 to rotate inside the sleeve 11, pushing the magnetic suction piece 14 to push the filter plate 18, so that the magnetic suction piece 14 and the magnetic suction piece 17 on the fixing piece 16 on the surface of the connecting frame 15 are magnetically connected, and the filter plate 18 is snapped and fixed, thus completing the replacement of the filter plate 18.

[0019] The front of the connecting frame 15 is overlapped with a filter plate 18. Both sides of the filter plate 18 are magnetically connected by magnetic clamping through A magnetic sheet 14 and B magnetic sheet 17. The filter plate 18 is connected by magnetic clamping to avoid damage to the filter plate 18 caused by bolt connection, which would lead to the filter plate 18 breaking and affect the filtration effect.

[0020] A filter screen 19 is fixedly connected inside the ventilation duct 1. The filter screen 19 is arranged in a linear array inside the ventilation duct 1. The filter screen 19 is distributed in a dispersed manner in the ventilation duct 1, which can enhance the filtration effect.

[0021] Specifically, when filter plate 18 needs to be replaced, the miniature electric push rod 7 is activated. The miniature electric push rod 7 drives the push rod 8 to extend and retract back and forth. During this extension and retraction, the push rod 8 drives the rotating block 9 and rotating component 10 to push forward. The rotating component 10 then pulls open the magnetic suction plate 3, separating it from the magnetic strip 6 on the inner wall of the ventilation duct 1. After the magnetic suction plate 3 is opened, the filter plate 18 inside the ventilation duct 1 is removed, and a new filter plate 18 is replaced. The filter plate 18 is placed on the connecting frame 15, and the miniature electric push rod 7 is activated to extend and retract the magnetic suction plate 3 inward, connecting the magnetic suction plate 3 to the ventilation duct 1. The magnetic strips 6 on the inner wall of the air duct 1 are magnetically connected, and the magnetic force is distributed by the magnetic block 5. The magnetic force is evenly distributed, avoiding local air leakage caused by uneven force due to traditional mechanical fixation. After the magnetic plate 3 and the visible plate 4 are covered on the surface of the ventilation duct 1, the threaded rod 13 is screwed into the sleeve 11. The threaded rod 13 drives the A magnetic plate 14 to rotate in the sleeve 11, pushing the A magnetic plate 14 against the filter plate 18, so that the A magnetic plate 14 is magnetically connected to the B magnetic plate 17 on the fixing plate 16 on the surface of the connecting frame 15, and the filter plate 18 is snapped and fixed, completing the replacement of the filter plate 18.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
