Description

Technical Field

[0001] This utility model belongs to the field of heating, ventilation and air conditioning technology, specifically a building heating, ventilation and air conditioning device. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) refers to the heating, ventilation, and air conditioning systems within buildings. Their primary function is to provide a comfortable indoor environment by regulating temperature, humidity, and airflow. HVAC systems include boilers, air conditioning units, fans, ducts, radiators, and other equipment. In winter, the system provides heat to keep the room warm; in summer, it cools and dehumidifies, providing fresh air. However, when replacing the internal filters of HVAC systems, the system must be temporarily shut down until the filters are removed, cleaned, and reinstalled. This replacement method affects the continuous and effective use of the HVAC system. Therefore, improvements are needed to address these issues. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 5 The present invention includes a ventilation duct 1, a connecting frame 2 fixedly installed in the middle of the ventilation duct 1, a through groove 3 opened in the middle of the connecting frame 2, an adjustable mounting plate 4 installed inside the through groove 3, limit plates fixedly installed at the top and bottom of the mounting plate 4, and mounting slots 5 matching the interior of the ventilation duct 1 opened at the upper and lower parts of the mounting plate 4, and detachable filter screens 6 installed inside the two mounting slots 5.

[0019] The mounting plate 4 has an inner cavity 7 in the middle of both sides of the two mounting slots 5. A pin A8 extending to the side of the mounting plate 4 is movably inserted into one side of the inner cavity 7, and a pin B9 extending into the inside of the mounting slot 5 is movably inserted into the other side of the inner cavity 7. The pins A8 and B9 are staggered. A sliding plate 10 is fixedly installed at the end of the pins A8 and B9 inside the inner cavity 7. A return spring 11 is fixedly installed between one side of the sliding plate 10 and the inner wall of the inner cavity 7.

[0020] An adjusting shaft A12 is rotatably mounted inside the inner cavity 7. Two eccentric wheels 13 are fixedly mounted on the surface of the adjusting shaft A12. The two eccentric wheels 13 are in contact with one side of the two slide plates 10 respectively. One end of the adjusting shaft A12 extends to the end of the mounting plate 4 and is fixedly mounted with a small bevel gear 14. A pair of mounting blocks 15 are fixedly mounted on both ends of the mounting plate 4. An adjusting shaft B16 is rotatably mounted between the two mounting blocks 15. Large bevel gears 17 that mesh with the small bevel gears 14 are fixedly mounted on both ends of the two adjusting shafts B16. Torsion springs 18 are sleeved on both sides of the two adjusting shafts B16. The two ends of the torsion springs 18 are fixedly connected to the mounting blocks 15 and the large bevel gears 17 respectively, so as to effectively adjust the pins A8 and B9.

[0021] Two insertion holes A19 are provided on both sides of the through groove 3 to cooperate with the pin A8. Extrusion slopes A20 are provided on both sides of the top and bottom of the through groove 3. A pressure-bearing slope A is provided at the end of the pin A8 to cooperate with the extrusion slope A20, thus effectively fixing the vertically moving mounting plate 4 and maintaining its stability. Limiting baffles 21 are fixedly installed on both sides inside the two mounting slots 5. Each of the two filter screens 6 includes a mounting frame 22 and a filter screen body 23 fixedly installed inside the mounting frame 22. The mounting frame 22 is installed inside the mounting slot 5 and limited by the two limiting baffles 21. Insertion holes B24 to cooperate with the pin A8 are provided in the middle of both sides of the two mounting frames 22. An extrusion slope B25 aligned with the insertion hole B24 is provided at one end of the middle of both sides of the two mounting frames 22. A pressure-bearing slope B is provided at the end of the pin B9 to cooperate with the extrusion slope B25, thus facilitating convenient disassembly and assembly of the filter screens 6 and stable installation and use.

[0022] As shown in Figure 1, when it is necessary to disassemble and replace the upper filter screen 6, first install the new or cleaned filter screen 6 in the mounting groove 5 at the bottom of the mounting plate 4; during installation, align the pressing slope B25 with the pin B9, and then press the mounting frame 22 so that the pressing slope B25 compresses the pin B9 through the pressure slope B. The pin B9 is compressed and the return spring 11 is compressed through the slide plate 10. When the socket B24 is aligned with the pin B9, the elastic restoring force of the return spring 11 will cause the pin B9 to be inserted into the socket B24, so that the mounting frame 22 can be stably installed in the mounting groove 5 at the bottom of the mounting plate 4.

[0023] Then, by rotating the adjusting shaft B16 on the upper part of the mounting plate 4, the adjusting shaft B16 drives the two large bevel gears 17 to rotate and tightens the two torsion springs 18. The rotation of the two large bevel gears 17 will drive the two small bevel gears 14 to rotate, which in turn drives the two adjusting shafts A12 to rotate. The rotation of the two adjusting shafts A12 will drive the two eccentric wheels 13 on them to rotate. The rotation of the two eccentric wheels 13 will squeeze and move the slide plate 10 and compress the return spring 11. The movement of the slide plate 10 will drive the pins A8 and B9 to move, thereby causing the pins A8 and B9 to be withdrawn from the inside of the sockets A19 and B24, respectively.

[0024] Then, by adjusting the mounting plate 4, the lower filter screen 6 is moved into the through groove 3. At the same time, by squeezing the inclined surface A20 and the pressure inclined surface A, the two pins A8 at the bottom of the mounting plate 4 are inserted into the socket A19, so that the filter screen 6 can be replaced stably and effectively, and the new or cleaned filter screen 6 can be moved to the middle of the connecting frame 2 for filtration.

[0025] The upward-moving mounting plate 4 will move the filter 6 that needs to be replaced to the top of the connecting frame 2, allowing for its disassembly and cleaning.

[0026] The building's HVAC system features a dual-layer filter replacement structure. This structure allows for rapid filter replacement during system operation without affecting the continuous and effective use of the system. Furthermore, the filter is easy to install and remove, ensuring stable and reliable installation and use. The design is simple, user-friendly, and easy to operate, and its performance meets the requirements of HVAC systems.
