[0002] In modern building construction, heating, ventilation, and air conditioning (HVAC) systems have become a crucial component. The main functions of HVAC systems include heating, ventilation, and air conditioning. HVAC systems often refer to individual central air conditioning systems, whose biggest advantage is creating a comfortable indoor environment. Therefore, with the improvement of people's living standards, the adoption of HVAC systems is becoming increasingly widespread. Currently, HVAC systems draw air from the outdoors, inevitably containing some dust and impurities. These dust and impurities, entering the house with the heating system, can easily affect human health. Therefore, a filtration system is needed to filter dust and impurities. However, current filtration systems are not easily disassembled for cleaning and replacement. Utility Model Content

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] like Figures 1-6As shown, this utility model provides a building heating and ventilation (HVAC) filter structure that is easy to disassemble. It includes an HVAC pipe 1 with an opening 2 on its side wall. A filter element 3 is detachably installed inside the HVAC pipe 1 at the opening 2. The filter element 3 is inserted into sliding grooves 4 at the top and bottom of the HVAC pipe 1 through the opening 2. A door panel 5 is hinged to the side of the opening 2 to close it. This utility model allows for easy replacement and cleaning of the filter element 3 by inserting it into the sliding grooves 4. When disassembly is needed, the filter element 3 can be pulled out of the sliding groove 4, a new filter element 3 can be inserted into the sliding groove 4, and then the door panel 5 can be closed. This improves the air quality of the incoming indoor heating system.

[0019] A raised frame 21 is provided at the edge of the opening 2, and a rubber sealing ring is provided on the frame 21. The door panel 5 covers the frame 21. The door panel 5 is fixed to the side wall of the heating and ventilation pipe 1 by a latch. The rubber sealing ring can prevent heating leakage at the opening 2. The latch is a prior art for opening and closing the door panel 5, which is not shown in the figure and will not be described in detail.

[0020] The filter component 3 includes a fixed frame 31 and multiple small filter screens 32. The fixed frame 31 is divided into multiple mounting compartments 33 by crisscrossing isolation rods, and a limiting frame 34 is provided at the bottom edge of each mounting compartment 33. The small filter screens 32 are positioned in the mounting compartments 33 by the limiting frame 34. This filter component 3 is composed of multiple small filter screens 32, allowing for individual replacement of small filter screens 32 in specific areas to address blockages, thus avoiding the need to replace the entire filter component 3 and saving resources.

[0021] The fixed frame 31 is also provided with a clamping frame 35 to hold the small filter screen 32 in place. The clamping frame 35 is also divided into multiple through holes corresponding to the mounting grid 33 by crisscrossing isolation rods. The edges of the through holes are provided with protruding positioning frames 36 that are inserted into the mounting grid 33 to clamp the small filter screen 32. After the small filter screen 32 is placed into the mounting grid 33, the clamping frame 35 is placed on the fixed frame 31, so that the positioning frames 36 are inserted into the mounting frame to clamp the small filter screen 32. Then, the fixed frame 31 and the clamping frame 35 are inserted together into the slide groove 4 to install and fix the filter component 3, thereby preventing the small filter screen 32 from falling out and ensuring that the small filter screen 32 is installed securely.

[0022] The bottom of the HVAC pipe 1 is provided with an outlet 6 for impurities to leak out, and a receiving trough 7 for receiving impurities is sleeved on the outlet 6.

The connecting sleeve 9 is rotatably connected to the bottom of the receiving groove 7 through a bearing. The upper end is located inside the receiving groove 7, and the lower end extends out of the receiving groove 7. The upper end is provided with a threaded hole that is threadedly connected to the lower end of the fixing rod 8. The receiving groove 7 is fitted onto the sleeve interface 61, and then the connecting sleeve 9 is rotated so that the connecting sleeve 9 is threadedly connected to the lower end of the fixing rod 8, thereby fixing the receiving groove 7 in place. Impurities blocked by the filter component 3 fall into the receiving groove 7 for temporary storage. When it is necessary to remove the receiving groove 7, the connecting sleeve 9 is rotated to remove it from the fixing rod 8, thereby removing the receiving groove 7 and emptying the impurities inside.

[0024] Work process: This utility model involves inserting the filter component 3 into the slide groove 4. When disassembly is required, the filter component 3 is pulled out of the slide groove 4, the clamping frame 35 is removed, the small filter screen 32 at the clogged part is replaced separately, the clamping frame 35 is then installed on the fixed frame 31 to press the small filter screen 32 tightly, and then the fixed frame 31 and the clamping frame 35 are inserted into the slide groove 4 together to install and fix the filter component 3. Then the door panel 5 is closed, thus completing the replacement of the filter component 3. When it is necessary to clean the impurities in the receiving trough 7, the connecting sleeve 9 is rotated to remove it from the fixed rod 8, thereby removing the receiving trough 7, emptying and cleaning the impurities inside, and then the receiving trough 7 is fitted onto the sleeve interface 61. Then the connecting sleeve 9 is rotated so that the connecting sleeve 9 is threadedly connected to the lower end of the fixed rod 8, thereby fixing the receiving trough 7 in place.
