Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and in particular to a heating, ventilation and air conditioning ventilation and filtration device. Background Technology

[0002] With the acceleration of industrialization and urbanization, indoor and outdoor air quality problems are becoming increasingly prominent, and people's requirements for indoor air quality are also getting higher and higher. Therefore, ventilation and filtration devices in HVAC systems must not only be able to effectively filter pollutants such as dust, bacteria, and viruses in the air, but also be able to adapt to changes in different environments and needs to ensure clean and healthy indoor air.

[0003] Most HVAC ventilation filtration devices currently on the market employ traditional fixed structural designs. The filter plates are typically fixed inside the device, making disassembly difficult. Over long-term use, large amounts of dust, impurities, pollen, and other pollutants continuously adhere to the filter plates. For example, in urban areas with poor air quality or industrial environments, a thick layer of dirt can accumulate on the filter plates in a short time. The inability to easily disassemble makes cleaning extremely inconvenient, often requiring only simple surface cleaning with external cleaning tools, which is insufficient to thoroughly remove the internal blockages. To address this technical problem, this application proposes an HVAC ventilation filtration device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a HVAC ventilation filter device. The rotating plate drives the limiting plate to rotate. The limiting plate makes the mounting plate unlock from the filter device body, so that the mounting plate can be removed from the filter device body. Pulling the slide rod compresses the second spring. Then, the limiting head is rotated, and under the action of the limiting block, the rotating rod is driven to rotate, thereby driving the second filter plate to rotate, so that it opens or closes inside the filter device body.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A rotating plate is fixedly connected to the rear end of the limiting plate. An installation plate is rotatably connected to the outer wall of the rotating plate. A torsion spring is provided on the rear side of the outer wall of the rotating plate. A filter plate is connected to the rear end of the installation plate via a slide rail. The filter plate is disposed on the inner wall of the filter body. A limiting component is provided on the left side of the front end of the filter body. A rotating rod is rotatably connected to the top side of the inner wall of the filter body. A filter plate is fixedly connected to the outer wall of the rotating rod.

[0008] Furthermore, the limiting component includes two pull rods located on the left side of the front end of the filter device body. The rear ends of the two pull rods are fixedly connected with tenons, and the outer walls of the two pull rods are provided with springs. The tenon on the left side is located at the bottom end of the limiting plate, and the tenon on the right side is located at the top end of the limiting plate.

[0009] Furthermore, one end of the torsion spring is disposed on the inner wall of the mounting plate, and the other end of the torsion spring is disposed on the front end of the limiting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1.

[0025] 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.

[0026] Reference Figures 1-3 An embodiment of this utility model provides a HVAC ventilation filtration device, comprising a filter device body 1, a limiting plate 6 rotatably connected to the inner wall of the filter device body 1, a rotating plate 5 fixedly connected to the rear end of the limiting plate 6, an mounting plate 2 rotatably connected to the outer wall of the rotating plate 5, a torsion spring 7 provided on the rear side of the outer wall of the rotating plate 5, a filter plate 4 connected to the rear end of the mounting plate 2 via a slide rail, the filter plate 4 being disposed on the inner wall of the filter device body 1, two pull rods 8 provided on the left side of the front end of the filter device body 1, a rotating rod 11 rotatably connected to the top side of the inner wall of the filter device body 1, a filter plate 12 fixedly connected to the outer wall of the rotating rod 11, a limiting head 17 connected to the inner wall of the rotating rod 11 via a slide rod 13, the limiting head 17 being disposed at the front end of the filter device body 1;

[0027] Specifically, with increased usage time, the filter plate will become clogged due to the accumulation of large amounts of dust, impurities, pollen, and other pollutants. When the filter plate is clogged, the ventilation resistance increases, leading to a decrease in airflow and an increase in energy consumption in the air conditioning system. At this point, simply rotating the rotating plate 5 will cause the limiting plate 6 to rotate, thereby releasing the mounting plate 2 from the filter device body 1. This allows the mounting plate 2 to be removed from the filter device body 1, enabling the filter plate 4 to be removed from the filter device body 1 via the tenon 3. The filter plate 4 can then slide off the tenon 3 and be removed from the mounting plate 2 for cleaning or replacement, ensuring that the ventilation system performance remains in good condition. Conversely, rotating the rotating plate 5 will cause the limiting plate 6 to rotate, inserting the mounting plate 2 into the groove of the filter device body 1. Releasing the rotating plate 5 will cause the limiting plate 6 to rotate back to its original position under the action of the torsion spring 7, thus limiting the mounting plate 2.

[0028] Reference Figures 4-6 The slide rod 13 is located on the inner wall of the rotating rod 11. A limit block 14 is fixedly connected to the rear side of the outer wall of the slide rod 13. The limit block 14 is slidably connected to the inner wall of the rotating rod 11. A spring 16 is provided in the middle of the outer wall of the slide rod 13. The slide rod 13 is fixedly connected to the top rear end of the limit head 17. Two pull rods 8 are located on the left side of the front end of the filter device body 1. The rear ends of both pull rods 8 are fixedly connected to tenons 9. Springs 10 are provided on the outer walls of both pull rods 8. The left tenon 9 is located at the bottom end of the limit plate 6, and the right tenon 9 is located at the top end of the limit plate 6. One end of the torsion spring 7 is located on the mounting plate 2. The inner wall has a torsion spring 7 with one end set at the front end of the limiting plate 6, a spring 10 with one end set at the inner wall of the filter body 1, and a tenon 9 with the other end set at the front end of the tenon 9. Two limiting plates 15 are set in the middle of the outer wall of the slide rod 13. The front limiting plate 15 is slidably connected to the outer wall of the slide rod 13, and the rear limiting plate 15 is fixedly connected to the outer wall of the slide rod 13. One end of the spring 2 16 is set at the rear end of the front limiting plate 15, and the other end of the spring 2 16 is set at the front end of the rear limiting plate 15. The mounting plate 2 is fixedly connected to the rear end of the tenon 3, and the tenon 3 is slidably connected to the front end of the filter plate 4.

[0029] Specifically, when it is necessary to increase or decrease the filtration level, pull the slide rod 13 to compress the spring 16, then rotate the limiting head 17, and under the action of the limiting block 14, drive the rotating rod 11 to rotate, thereby driving the filter plate 12 to rotate. After rotating 90 degrees, release the force applied to the slide rod 13, and under the action of the spring 16, the limiting head 17 will spring into the corresponding slot, limiting the filter plate 12 so that it can open or retract within the filter device body 1, thus flexibly meeting different usage scenarios and user needs. When it is necessary to rotate the limiting plate 6 to remove the mounting plate 2 from the filter device body 1, During disassembly, first pull the lever 8 to move the tenon 9, so that the tenon 9 can release the limiting plate 6. When it is necessary to rotate the limiting plate 6 to lock the mounting plate 2 into the filter device body 1, when the limiting plate 6 rotates and touches the tenon 9, it can slowly move under the action of the shape of the tenon 9, so that the limiting plate 6 can pass through the tenon 9. When the limiting plate 6 reaches the appropriate position, the tenon 9 will spring back to its original position under the action of the first spring 10, limiting the limiting plate 6. The second spring 16 can be limited by the limiting piece 15, so that the sliding rod 13 rotates and drives the second spring 16 to rotate together, preventing damage to the second spring 16.

[0030] Working principle: When cleaning or replacing filter plate 4 is required, first pull rod 8 to move tenon 9, compressing spring 10, causing tenon 9 to release its restriction on limiting plate 6. Then rotate rotating plate 5 to rotate limiting plate 6, allowing mounting plate 2 to release its engagement with filter device body 1, thus removing mounting plate 2 from filter device body 1. This allows filter plate 4 to be removed from filter device body 1 via tenon 3 for replacement or cleaning. After cleaning, rotate rotating plate 5 to rotate limiting plate 6, inserting mounting plate 2 into the groove of filter device body 1. Release rotating plate 5; under the action of torsion spring 7, limiting plate 6 will rotate back to its original position. When limiting plate 6 rotates to contact... When the tenon 9 is encountered, it can slowly move under the action of the shape of the tenon 9, so that the limiting plate 6 can pass through the tenon 9. When the limiting plate 6 reaches the appropriate position, the tenon 9 will spring back to its original position under the action of the first spring 10, limiting the limiting plate 6. The mounting plate 2 is limited by the limiting plate 6. When it is necessary to increase or decrease the filtration degree, pull the slide rod 13 to compress the second spring 16, then rotate the limiting head 17, and drive the rotating rod 11 to rotate under the action of the limiting block 14, thereby driving the filter plate 12 to rotate. After rotating 90 degrees, the force applied to the slide rod 13 is released, and the limiting head 17 is springed into the corresponding slot under the action of the second spring 16, limiting the filter plate 12, so that it can open or retract within the filter device body 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
