[0002] The origins of architecture can be traced back to ancient times. It gradually arose and developed as humankind sought to meet its own needs for survival and development. The emergence of cities spurred the diversification and scaling of architecture. Cities required buildings with various functions, such as palaces, temples, markets, residences, and city walls. Urban planning and architectural layout gradually gained importance to meet people's needs for living, production, and social interaction. From the earliest simple shelters to today's modern high-rise buildings, the development of architecture reflects the progress of human society, technological innovation, and the inheritance and evolution of culture.

[0003] In existing technologies, in daily life, residences need to maintain good ventilation to keep indoor air fresh. Filter devices can effectively filter common pollutants such as dust, pollen, and pet hair in the air, providing residents with a healthy indoor air environment. They are especially suitable for people with high requirements for air quality. However, during use, filter devices can usually only perform simple dust filtration and cannot filter pollutants and harmful gases of different particle sizes. In addition, the filter screens in the filter devices generally need to be disassembled and cleaned frequently by hand, which increases labor costs.

[0004] Therefore, a filtration device for indoor ventilation in buildings is proposed. Summary of the Invention

[0023] 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.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1:

[0026] Based on the existing problems that filter devices can only perform simple dust filtration during use and cannot filter pollutants and harmful gases of different particle sizes, and the filter screens in the filter devices generally require frequent manual disassembly and cleaning, increasing labor costs, the present invention provides a preferred embodiment of a filter device for indoor ventilation in buildings, as shown in Figures 1-5: A filter device for indoor ventilation in buildings includes a wall 1, an air exchange pipe 2 is arranged between the inner walls of the wall 1, a ventilation cavity 3 is arranged inside the air exchange pipe 2, a multi-stage filter assembly 4 is arranged inside the ventilation cavity 3, and an automatic dust removal assembly 5 is arranged at the bottom of the air exchange pipe 2.

[0027] The multi-stage filter assembly 4 specifically includes: a concave plate 411, fixedly installed on the top of the air exchange pipe 2; a motor 412, fixedly installed on the top of the inner wall of the concave plate 411; a rotating rod 413, fixedly installed on the output end of the motor 412; a connecting ring 417, evenly and equidistantly arranged between the inner walls of the air exchange pipe 3; and a side block 419, evenly and equidistantly fixedly installed on the outer wall of the air exchange pipe 2. The bottom of the air exchange pipe 2 is provided with holes evenly and equidistantly. The other end of the rotating rod 413 moves sequentially through the bottom of the inner wall of the concave plate 411, the top of the air exchange pipe 2, and the inner wall of the air exchange pipe 2, extending to the bottom of the air exchange pipe 2. A baffle plate 414 is fixedly sleeved on the outer wall of the rotating rod 413, and an arc plate 415 is engaged with the inner wall of the hole.

[0028] The outer circumference of the arc plate 415 is fixedly installed with groove blocks 416 at equal intervals. The inner side of the arc plate 415 is fixedly connected to the outer wall of the connecting ring 417. A filter screen 418 is fixedly installed between the inner walls of the connecting ring 417.

[0029] A pull ring 4111 is provided on one side of the side block 419. A plug rod 4112 is fixedly connected to one side of the pull ring 4111. The other end of the plug rod 4112 moves through one side of the side block 419 and extends to engage with the inner wall of the groove block 416.

[0030] A retrieval ring 4113 is fixedly sleeved on the outer wall of the insertion rod 4112, and a spring 4114 is movably sleeved on the outer wall of the insertion rod 4112. One end of the spring 4114 is fixedly connected to one side of the inner wall of the side block 419, and the other end of the spring 4114 is fixedly connected to one side of the retrieval ring 4113.

[0031] In this example, filtration and purification can be achieved by setting up a multi-stage filtration assembly 4. The motor 412 drives the rotating rod 413 and the baffle 414 to rotate, which can adjust the air intake of the ventilation pipe 3. Filtration is carried out through three layers of filter screens 418. The first layer is a polypropylene filter screen for filtering larger particles, the second layer is a glass fiber fine filter screen for filtering fine particles, and the third layer is an activated carbon filter screen for adsorbing harmful gases, thereby achieving the effect of multi-stage filtration.

[0032] Example 2:

[0033] Based on Embodiment 1, a preferred embodiment of the filtration device for indoor ventilation in buildings provided by this utility model is shown in Figures 1-5: The automatic dust removal component 5 specifically includes: a locking block 511, which is equidistantly and uniformly fixedly installed on the top of the inner wall of the ventilation pipe 2; a curved plate 512, which is disposed inside the ventilation pipe 2; a collection box 516, which is equidistantly and uniformly connected to the bottom of the ventilation pipe 2; and a vacuum cleaner 518, which is disposed at the bottom of the ventilation pipe 2.

[0034] The outer wall of the locking block 511 fits against the inner wall of the connecting ring 417. One side of the bent plate 512 is fixedly connected to one side of the locking block 511. A second motor 513 is fixedly installed on the inner side of the bent plate 512. A second rotating rod 514 is fixedly installed at the output end of the second motor 513. The other end of the second rotating rod 514 moves through one side of the locking block 511 and extends to the other side of the locking block 511. A cleaning brush 515 is fixedly sleeved on the outer wall of the second rotating rod 514 at equal intervals.

[0035] A hose 517 is connected to the bottom of the collection box 516, a suction tube 519 is connected to the top of the vacuum cleaner 518, and a suction box 5111 is connected to the other end of the suction tube 519. The bottom of the suction box 5111 is in contact with the top of the vacuum cleaner 518, and one side of the vacuum cleaner 518 is connected to the other end of the hose 517.

[0036] In this example, automatic dust removal can be achieved by setting up the automatic dust removal component 5. The second motor 513 is started to drive the second rotating rod 514 to rotate, which drives the cleaning brush 515 to rotate and clean the filter screen 418. At the same time, the vacuum cleaner 518 is started to work. The dust generated during cleaning is collected by the collection box 516. The dust enters the vacuum cleaner 518 through the hose 517, suction box 5111, and suction tube 519 for collection, thereby achieving the function of automatic dust removal.

[0037] Working principle: First, air is introduced through one side of the ventilation pipe 2 and filtered through a three-layer filter screen 418. The first layer is a polypropylene filter screen for filtering larger particles, the second layer is a fine glass fiber filter screen for filtering fine particles, and the third layer is an activated carbon filter screen for adsorbing harmful gases. When the air intake needs to be adjusted, motor 412 drives the rotating rod 413 and the baffle 414 to rotate, thereby adjusting the air intake of the ventilation pipe 3. When automatic dust removal of the filter screen 418 is required, motor 513 is started to drive the rotating rod 514 to rotate, which drives the cleaning brush 515 to clean the filter screen 418. The system performs rotational cleaning while simultaneously activating the vacuum cleaner 518. Dust generated during cleaning is collected via the collection box 516 and enters the vacuum cleaner 518 through the hose 517, suction box 5111, and suction tube 519. When manual cleaning of the filter 418 is required, pulling the pull ring 4111 moves the insertion rod 4112 and the recovery ring 4113, compressing the spring 4114. The insertion rod 4112 separates from the groove block 416, and under gravity, the arc plate 415 and connecting ring 417 descend, thus cleaning the filter 418. This achieves multi-stage filtration and automatic dust removal.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
