Technical Field

[0001] This utility model relates to the field of building decoration engineering technology, and in particular to a fresh air device for interior decoration engineering. Background Technology

[0002] Traditional fresh air systems have many drawbacks in interior decoration projects. Some products use an integrated filter structure, which requires complete disassembly for filter replacement, making the operation cumbersome and inefficient. Some systems have a single filtration level, making it difficult to remove multiple pollutants such as PM2.5, formaldehyde, and odors at the same time. This fresh air system aims to solve the above problems and improve indoor air quality and equipment practicality through modular filter components and optimized connection structure design.

[0005] The filtering device includes a first connecting circular block, a filtering assembly, and a housing. A threaded strip is fixedly connected to the inner wall of the first connecting circular block. Several connecting blocks are fixedly connected to the right side of the outer surface of the first connecting circular block. Each of the connecting blocks has a through slot on its left side. Several housings are provided. A movable groove is provided on the upper left side of each housing. A push block is slidably connected in the movable groove. One end of the push block passes through the housing and is fixedly connected to a stop block.

[0006] Preferably, the outer surface of the fan housing is provided with a second threaded hole that matches the four screws, and the four screws pass through the first threaded hole and are threadedly connected to the second threaded hole.

[0007] The above solution allows the fan casing and ventilation duct body to be detachably and fixedly connected by screws, ensuring stable installation and facilitating disassembly and maintenance, thus improving the convenience of fan inspection and replacement.

[0009] The above solution allows for easy removal of the filter components via a sliding connection between the slide and the plate, using an arc-shaped handle. This enables individual replacement of the primary, medium, and high-efficiency filters, simplifying maintenance and providing excellent purification results.

[0010] Preferably, the second connecting block has a cylindrical structure, and the right end of the second connecting block has several ventilation holes that pass through from left to right.

[0024] In this embodiment, the filter device 6 includes a first connecting circular block 61, a filter assembly 65, and a housing 66. A threaded strip 62 is fixedly connected to the inner wall of the first connecting circular block 61. A plurality of connecting blocks 63 are fixedly connected to the right side of the outer surface of the first connecting circular block 61. A slot 64 that passes through the left side is opened at the left end of each of the plurality of connecting blocks 63. A plurality of housings 66 are provided. A movable groove 67 is opened at the upper left end of each of the plurality of housings 66. A push block 68 is slidably connected in the movable groove 67. One end of the push block 68 passes through the housing 66 and is fixedly connected to a stop block 69. A second threaded hole adapted to four screws 4 is opened on the outer surface of the fan housing 3. The four screws 4 pass through the first threaded hole 2 and are threadedly connected to the second threaded hole.

[0025] With the above solution: During installation, the ventilation duct body 1 and the fan housing 3 are fixed with screws 4. The screws 4 pass through the first threaded hole 2 of the ventilation duct body 1 and are screwed into the second threaded hole of the fan housing 3 to achieve a stable connection. When installing the filter device 6, the first connecting block 61 is threaded to the external pipe through the threaded strip 62. Then, the movable groove 67 on the outer shell 66 is aligned with the slot 64 of the connecting block 63 and inserted. The push block 68 is pushed so that the stop block 69 is engaged in the slot 64, thus completing the fixation of the first connecting block 61 and the outer shell 66. When in use, the fan 5 works to generate airflow. The air is filtered through multiple stages by the filter device 6 and then sent into the room to achieve the fresh air function. When disassembling, the push block 68 and screws 4 can be reversed for convenient maintenance.

[0026] In this embodiment, the filter assembly 65 includes a second connecting circular block 651. A groove 652 is provided on the upper part of the inner wall surface of the second connecting circular block 651. A sliding plate 653 is slidably connected in the groove 652. A fixing plate 654 is fixedly connected to the lower end of the sliding plate 653. An arc-shaped handle 655 is fixedly connected to the lower end of the fixing plate 654. A primary filter 656, a medium-efficiency filter 657, and a high-efficiency filter 658 are fixedly connected from left to right on the lower end of the fixing plate 654. The second connecting circular block 651 has a cylindrical structure, and a number of ventilation holes that pass through it to the left and right are provided on the right end of the second connecting circular block 651. A number of outer shells 66 are inserted into a number of slots 64. The first connecting circular block 61 and the second connecting circular block 651 are engaged by a connecting block 63 and a stop block 69. The positions of the number of outer shells 66 and the number of connecting blocks 63 are opposite to each other, and the number of slots 64 are arranged in a ring array around the center of the first connecting circular block 61.

[0027] With the above solution: During installation, the outer casing 66, driven by the push block 68, moves the stop block 69 into the slot 64 of the connecting block 63, achieving the engagement of the first connecting block 61 and the second connecting block 651. The circular array of slots 64 ensures uniform force distribution. The filter assembly 65 slides within the groove 652 of the second connecting block 651 via the sliding plate 653. Combined with the arc-shaped handle 655, it can be pulled out for easy filter replacement. During operation, the airflow generated by the fan 5 enters through the ventilation duct body 1, passing sequentially through the primary filter 656 to filter large particles, the medium-efficiency filter 657 to intercept pollutants such as PM10, and the high-efficiency filter 658 to purify fine particles such as PM2.5. The purified air flows into the room through the ventilation hole at the right end of the second connecting block 651. For disassembly and maintenance, simply release the push block 68 and pull out the filter assembly 65 to replace each filter individually, eliminating the need for complete disassembly and improving ease of use.

[0028] It should be noted that this utility model is a fresh air device for indoor decoration projects. In the process of use, firstly, when installing the device, place the fan housing 3 inside the ventilation pipe body 1, align the second threaded hole on the outer surface of the fan housing 3 with the first threaded hole 2 on the outer surface of the ventilation pipe body 1, and use a screw 4 to pass through the first threaded hole 2 and screw it into the second threaded hole to fix the fan housing 3. Securely install the fan 5 inside. Next, install the filter device 6, screw the threaded strip 62 of the first connecting round block 61 into the left end of the ventilation pipe body 1 to complete the initial fixation, align the left end of the outer shell 66 with the connecting block 63, so that the movable groove 67 corresponds to the slot 64, push the push block 68, and drive the stop block 69 to insert into the slot 64, engaging the first connecting round block 61 and the second connecting round block 651. When the filter needs to be replaced, pull the arc handle 655 to make the slide plate 653 slide along the slide groove 652, and pull out the filter assembly 65. The primary, medium and high efficiency filters can be replaced individually, making maintenance and operation simple.
