Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, specifically a ventilation duct with an air purification module. Background Technology

[0002] In industrial production, commercial buildings, and residential settings, ventilation systems are essential facilities for ensuring air circulation and maintaining ambient air quality. As a core component of the ventilation system, the performance of ventilation ducts directly affects the ventilation effect.

[0003] Currently, most common ventilation ducts on the market can only achieve one-way or two-way airflow and lack effective air purification functions. When the air contains a lot of dust, particulate matter, odors, or other harmful impurities, these pollutants will enter the indoor or workplace environment during the ventilation process, affecting not only human health but also polluting the environment. To solve the air purification problem, some ventilation equipment is equipped with additional filters. However, the existing filters are mostly fixed to the ventilation duct with bolts. When cleaning or replacing the filter components, a cumbersome disassembly operation with tools is required, which is not only time-consuming and labor-intensive but also causes many inconveniences for users. Therefore, this utility model proposes a ventilation duct with an air purification module to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation duct with an air purification module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation duct with an air purification module, comprising a main ventilation duct, a diversion cavity communicating with the main ventilation duct, and two connecting ducts communicating with the diversion cavity. A frame is detachably provided inside the connecting duct, and a filter plate is integrated inside the frame. A rotary drive mechanism is provided on the connecting duct. The rotary drive mechanism includes a bidirectional threaded rod rotatably disposed at the lower end of the connecting duct. A movable folding plate is threadedly connected to each of the two reverse threads of the bidirectional threaded rod. A limiting groove is provided on the frame for the movable folding plate to extend into.

[0006] Preferably, a fixing block is fixedly installed at the lower end of the connecting cylinder, and a bidirectional threaded rod is rotatably connected inside the fixing block.

[0007] Preferably, both ends of the bidirectional threaded rod are fixedly connected to a fixing button, and one end of the movable folding plate slides into the inside of the connecting cylinder.

[0008] Preferably, a fixed straight plate is fixedly installed between the two connecting cylinders, and the two movable folding plates are slidably installed on the fixed straight plate.

[0009] Preferably, the connecting cylinder has an installation groove inside, which allows the frame to slide into.

[0010] Preferably, the filter plate is connected to the frame by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Equipped with a rotary drive mechanism, rotating the fixed knob will drive the bidirectional threaded rod to rotate. The bidirectional threaded rod will drive the two movable folding plates to move closer to each other along the fixed straight plate to unlock, or move further apart to lock, thereby disengaging from or extending into the limiting groove on the frame, realizing quick disassembly and assembly of the frame and filter plate without tools, and making operation convenient.

[0013] 2. By setting two connecting cylinders and two filter plates, during the ventilation process, after the air enters the diversion chamber through the main ventilation cylinder, it can be simultaneously diverted to the two connecting cylinders and purified synchronously through the two filter plates. This dual-path purification design greatly increases the amount of air purified per unit time, improves the overall air purification efficiency, and can quickly improve the air quality in the ventilation area.

[0019] 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.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a ventilation duct with an air purification module, including a main ventilation duct 1, a diversion cavity 2 communicating with the main ventilation duct 1, and two connecting ducts 3 communicating with the diversion cavity 2. A frame 4 is detachably installed inside the connecting duct 3, and a filter plate 5 is integrated inside the frame 4. A rotary drive mechanism is provided on the connecting duct 3, including a bidirectional threaded rod 7 rotatably installed at the lower end of the connecting duct 3. Movable folding plates 8 are threadedly connected to the two reverse threads of the bidirectional threaded rod 7. A limiting groove 10 is provided on the frame 4 for the movable folding plates 8 to extend into. By providing the rotary drive mechanism, rotating the fixing knob 12... The bidirectional threaded rod 7 can rotate, and the bidirectional threaded rod 7 drives the two movable folding plates 8 to move closer to each other along the fixed straight plate 9 to unlock, or move further apart to lock, thereby disengaging from or extending into the limiting groove 10 on the frame 4, realizing the quick disassembly and assembly of the frame 4 and the filter plate 5 without tools, and the operation is convenient. By setting two connecting cylinders 3 and two filter plates 5, during the ventilation process, after the air enters the diversion chamber 2 through the ventilation main cylinder 1, it can be simultaneously diverted to the two connecting cylinders 3, and undergo synchronous purification treatment through the two filter plates 5. This dual-path purification design greatly improves the amount of air purified per unit time and improves the overall air purification efficiency.

[0021] like Figure 3 As shown, a fixing block 6 is vertically fixed to the lower end of the connecting cylinder 3 by welding. A bidirectional threaded rod 7 is rotatably connected inside the fixing block 6. Fixing buttons 12 are welded to both ends of the bidirectional threaded rod 7. One end of the movable folding plate 8 slides into the interior of the connecting cylinder 3. By rotating the fixing button 12, the bidirectional threaded rod 7 can be driven to rotate inside the fixing block 6.

[0022] like Figure 3 as well as Figure 4 As shown, a fixed straight plate 9 is welded and fixed between the two connecting cylinders 3, and two movable folding plates 8 are slidably installed on the fixed straight plate 9. An installation groove 11 is opened inside the connecting cylinder 3, and the installation groove 11 allows the frame 4 to slide into it. The filter plate 5 and the frame 4 are connected by bolts evenly distributed around the circumference passing through the reserved holes.

[0023] During the ventilation and purification process, air first enters the main ventilation duct 1, then flows into the diversion chamber 2 connected to it. After being diverted by the diversion chamber 2, it enters two connecting ducts 3. Since a frame 4 is inserted into the mounting groove 11 inside the connecting duct 3, and a filter plate 5 is integrated inside the frame 4, the air will pass through the filter plate 5 to complete the purification, and then be discharged from the connecting duct 3. When it is necessary to remove the filter plate 5 for cleaning or replacement, turn the fixing knob 12. The fixing knob 12 drives the bidirectional threaded rod 7 connected to it to rotate in the fixing block 6. Since the two reverse threads of the bidirectional threaded rod 7 are both threaded with movable folding plates 8, and the movable folding plates 8 slide... Installed on the fixed straight plate 9 between the two connecting cylinders 3, the rotation of the bidirectional threaded rod 7 will cause the two movable folding plates 8 to move closer to each other and then move out of the limiting groove 10 on the frame 4. At this time, the frame 4 can be pulled out from the mounting slide groove 11 of the connecting cylinder 3 to remove the filter plate 5. When installing the filter plate 5, insert the frame 4 with the filter plate 5 into the mounting slide groove 11 of the connecting cylinder 3, rotate the fixing knob 12 in the opposite direction, and the bidirectional threaded rod 7 will drive the two movable folding plates 8 to move away from each other, so that they are inserted into the limiting groove 10 on the frame 4, completing the installation and fixing of the filter plate 5. Then the ventilation duct can continue to perform ventilation and purification work.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
