[0002] During the installation of the fresh air system, the treatment of the entrance of the fresh air duct is particularly critical. The traditional practice is to connect the blinds to the reducer duct joint and isolate insects and birds through the grille of the blinds. This is because birds and insects can easily enter the fresh air duct through the gaps in the blinds. Their corpses will pollute the indoor air and even bring the risk of bacterial growth. Some people also add a metal mesh between the inside of the blinds and the reducer duct joint for a certain degree of isolation, but it cannot meet the requirements of simple disassembly and assembly, and is not easy to clean. Over time, not only will the indoor air quality be affected, but the metal mesh will also hinder wind power after being clogged, affecting the effect of the fresh air system.

[0025] like Figures 1 to 3 As shown, the utility model includes a detachable protection mechanism 2 arranged at the reducer air duct joint 1 and the inlet of the fresh air duct 3, the detachable protection mechanism 2 includes a connection frame connected to the reducer air duct joint 1 and the inlet of the fresh air duct 3 and a first protection net 2-4 and a second protection net 2-5 detachably inserted in the connection frame, and the ends of the first protection net 2-4 and the second protection net 2-5 are provided with handles 2-8;

[0026] The first protection net 2-4 and the second protection net 2-5 are both nylon nets.

[0027] In this embodiment, the connecting frame includes a circular frame 2-1, a first extension plate 2-3 integrally formed with the outer edge of the front side of the circular frame 2-1, and a second extension plate 2-9 integrally formed with the outer edge of the rear side of the circular frame 2-1. The first extension plate 2-3 and the connecting part of the reducing air duct joint 1 are connected by a first bolt, and the second extension plate 2-9 and the inlet connecting part of the fresh air duct 3 are connected by a second bolt.

[0028] In this embodiment, an integrally formed middle cross bar 2-2 is provided inside the circular frame 2-1, and the middle cross bar 2-2 divides the circular frame 2-1 into a first installation cavity and a second installation cavity. The first installation cavity is provided with a first embedding groove 2-6 for inserting the first protective net 2-4, and the second installation cavity is provided with a second embedding groove 2-7 for inserting the second protective net 2-5.

[0029] In this embodiment, an opening is provided in the right frame of the circular frame 2-1 for plugging in and out of the first protection net 2-4 and the second protection net 2-5.

[0030] In this embodiment, a first sealing ring is provided at the connection portion between the first extension plate 2 - 3 and the variable diameter air duct joint 1 , and a second sealing ring is provided at the connection portion between the second extension plate 2 - 9 and the inlet of the fresh air duct 3 .

[0031] In this embodiment, a connecting frame and a first protective net 2-4 and a second protective net 2-5 detachably inserted in the connecting frame are provided, so that when the connecting frame is added to the reducer air duct joint 1 and the inlet of the fresh air duct 3, only the first protective net 2-4 and the second protective net 2-5 need to be disassembled and assembled, which is convenient to operate and does not affect the performance of the reducer air duct joint 1 and the inlet device of the fresh air duct 3.

[0032] In this embodiment, the first protective net 2-4 and the second protective net 2-5 are set, which not only prevent pollutants such as insects and birds from entering the fresh air duct, ensuring the freshness and health of indoor air; but also the two protective nets are convenient for pulling out and selectively replacing, thereby improving adaptability.

[0033] In this embodiment, the handle 2-8 is provided to drive the first protection net 2-4 and the second protection net 2-5 to be pulled out or inserted through the handle 2-8, so as to realize the installation and removal of the protection nets and facilitate the operation.

[0034] In this embodiment, the first protection net 2-4 and the second protection net 2-5 are both double-layer nylon nets embedded in the frame, and the aperture is 80 meshes. They are easy to install and maintain, corrosion-resistant, and have high strength.

[0035] In this embodiment, the first embedding groove 2-6 and the second embedding groove 2-7 make the frames of the first protective net 2-4 and the second protective net 2-5 connected to the embedding groove equivalent to the sliding rail groove, which not only ensures the stability and durability of the device, but also makes the pulling and pulling of the protective net smoother.

[0036] In this embodiment, due to the detachable design, the user can regularly check and clean the protective net to avoid blockage and wind obstruction. Compared with the fixed metal net in the prior art, this product can ensure the normal ventilation and efficient operation of the fresh air system while maintaining the protective effect. Secondly, the metal net is difficult to clean and maintain because it is closely connected to the air duct opening. The detachable pull-out design allows the user to easily take out the protective net for cleaning or replacement, which greatly simplifies the maintenance process and reduces maintenance costs. Furthermore, the protective net design can more effectively prevent objects such as birds and insects from entering the fresh air system. Its fine mesh design ensures air circulation while effectively blocking the entry of external pollutants; finally, after the protective net is precisely docked and sealed with the air duct opening, the docking and sealing effects of the connection are not changed, which extends the service life of the device.

[0037] In this embodiment, it should be noted that the first sealing ring and the second sealing ring are not shown in the figure.

[0038] When the utility model is used, the connection part of the first extension plate 2-3 and the reducer air duct joint 1 is connected by a first bolt, and the second extension plate 2-9 and the inlet connection part of the fresh air duct 3 are connected by a second bolt, so that the detachable protective mechanism 2 is added between the reducer air duct joint 1 and the inlet of the fresh air duct 3.

[0039] When the fresh air system is running, air enters through the variable diameter air duct joint 1, the detachable protective mechanism 2 and the fresh air duct 3. In this way, birds, insects, some dust and other objects are effectively blocked out after being filtered by the detachable protective mechanism 2. The first protective net 2-4 and the second protective net 2-5 can also be pulled out along the first embedded groove 2-6 and the second embedded groove 2-7 and the opening at any time for cleaning or replacement as needed. After cleaning or replacement, the first protective net 2-4 and the second protective net 2-5 are inserted along the first embedded groove 2-6 and the second embedded groove 2-7 and the opening and pushed back to their original positions. During the whole process, the sealing ring always keeps a close fit with the air duct opening to ensure the sealing and insect-proof effect of the system, effectively solving the problems of poor protection effect, difficulty in cleaning and maintenance, and influence on wind force in the prior art, and improving the use effect and user experience of the fresh air system.

[0040] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
