Referring to Figures 1 to 4, the utility model provides a fresh air housing structure for improving noise and a fresh air fan 100 having a fresh air housing structure. The fresh air fan 100 is used to transport outdoor fresh air to the room and discharge indoor turbid air to the outside. Preferably, the fresh air fan 100 can be installed and fixed to the bearing structure through the mounting member 3, and the bearing structure refers to the load-bearing structure indoors for carrying and fixing the fresh air fan 100, for example, it can be a house wall, a ceiling structure, an indoor ceiling, etc. The fresh air fan 100 includes a fresh air housing structure, and a duct 11 connecting indoors and outdoors is formed in the fresh air housing structure. A fan component 5 can be arranged in the duct 11 to drive the air flow through the duct 11, flowing from the outside to the room, and providing outdoor fresh air to the room. Preferably, a filter component 6 can also be arranged in the duct 11 to filter out impurities in the outdoor air to improve the indoor air quality, and can include one or more of a high-efficiency filter, a medium-efficiency filter, a primary filter, a photocatalyst filter, an activated carbon filter, etc.

Please continue to refer to Figures 1 to 4. The fresh air housing structure includes a housing plate 1 and a wind tube 2. The housing plate 1 is a part of the fresh air housing structure, and is opened to connect the air outlet of the air duct 11 located on the inner side of the housing plate 1. The wind tube 2 is integrally arranged on the outer side of the housing plate 1 and is sleeved on the outer periphery of the air outlet. In this embodiment, the wind tube 2 is used to connect the air supply pipe leading to the indoor and/or outdoor, so as to transport the air flow according to the designed path and ensure the air tightness of the air supply flow path. Specifically, the air duct 11 has at least an air inlet and an air outlet. When the fan component 5 is working, the air flow is driven to flow from the air inlet into the air duct 11 and is sent out from the air outlet. The air inlet can be directly connected to the outdoor through the wind tube 2, or connected to the air supply pipe connected to the outdoor, and the air outlet can be directly connected to the indoor, or connected to the air supply pipe connected to the indoor. In the fresh air shell structure disclosed by the utility model, the casing plate 1 can be set as one piece, wherein the air inlet and the air exhaust outlet are both arranged on the casing plate 1, or the casing plate 1 can be provided with multiple pieces, and the multiple casing plates are distributed on different sides of the fresh air shell structure, wherein the air inlet and the air exhaust outlet are distributed on the casing plates on different sides according to the actual air supply and exhaust directions.

In this embodiment, the air duct 2 is integrally arranged with the casing plate 1, so that the fresh air fan 100 does not need to connect the air duct 2 and the casing plate 1 through fasteners during the production process, thereby improving assembly efficiency, reducing the holes on the outer casing of the air duct 11, improving the sealing performance of the air duct 11, reducing the gaps on the outer casing of the fresh air fan 100, and improving the noise during the use of the fresh air fan 100.

There are many ways to integrate the air duct 2 and the casing plate 1. For example, the air duct 2 and the casing plate 1 are both made of metal and are welded together, or the air duct 2 is bonded to the outside of the casing plate 1 by a strong adhesive. In a possible embodiment, the air duct 2 and the casing plate 1 are integrally formed by injection molding or die casting. This can further simplify the production process and reduce costs. It is understood that the air duct 2 and the casing plate 1 can also be made of materials with strong deformation resistance and load-bearing capacity, such as engineering plastics, aluminum alloys, etc.

Preferably, as shown in FIG1 , the air duct 2 includes a first tube section 21 attached to the outside of the casing plate 1, and a second tube section 22 extending from the first tube section 21 in a direction away from the casing plate 1, and the cross-sectional size of the first tube section 21 is gradually reduced from the outside of the casing plate 1 to the second tube section 22. In this way, the air flow velocity at the inlet and outlet air supply pipes can be increased, and the ventilation efficiency can be improved, while the air flow entering the air duct 11 is slowed down, and the ventilation area is increased. On the one hand, the air supply area of the fan component 5 is increased, and the air supply volume is increased. On the other hand, the air flow velocity in the air duct 11 is slowed down, and the operating noise of the fresh air blower 100 is reduced.

Please continue to refer to Figures 1 and 4. Further, the fresh air housing structure also includes a mounting member 3, which is integrally arranged on the outer side of the housing plate 1, and is used to connect the bearing structure. In this way, the fresh air fan 100 can be easily installed on a wall or other locations, and the mounting member 3 does not need to be installed on the housing plate 1 through fasteners, which improves the efficiency of on-site assembly, reduces the number of holes on the housing of the air duct 11, improves the sealing performance of the air duct 11, reduces the gaps on the housing of the fresh air fan 100, and improves the noise during the use of the fresh air fan 100.

There are many ways to integrate the mounting member 3 and the housing plate 1. For example, the mounting member 3 and the housing plate 1 are both made of metal and are welded together, or the mounting member 3 is bonded to the outside of the housing plate 1 by a strong adhesive. In a possible embodiment, the mounting member 3 and the housing plate 1 are integrally formed by injection molding or die casting. This can further simplify the production process and reduce costs. It is understandable that the mounting member 3 and the housing plate 1 can also be made of materials with strong deformation resistance and load-bearing capacity, such as engineering plastics and aluminum alloys.

The shape and structure of the mounting member 3 can be various, and according to the specific installation method of the fresh air fan, the shape and structure of the mounting member 3 can be designed according to actual needs. In one embodiment provided by the present utility model, as shown in FIG4 , the mounting member 3 includes a main body 31 protruding outward from the outside of the casing plate 1, and reinforcing plates 32 provided at both ends of the main body 31 and respectively connected to the casing plate 1, the main body 31 is provided with mounting holes 33 in the up-down direction, and the main body 31 is provided with reinforcing ribs 34 protruding on one side in the up-down direction, and a plurality of reinforcing ribs 34 are provided at intervals between the two reinforcing plates 32. In this embodiment, the fresh air fan 100 can be fixedly connected to the bearing structure by fasteners such as bolts passing through the mounting holes 33, and the provision of the reinforcing ribs 34 and the reinforcing plates 33 can enhance the structural strength and stability of the mounting member 3, and prevent the mounting member 3 from being deformed or broken during use. Preferably, at least two mounting parts 3 can be provided on the casing plate 1, thereby increasing the stress points on each casing plate 1, so that after the fresh air fan 100 is installed, its fresh air shell structure can bear a reasonable load and force, is not prone to excessive concentrated stress, and extends its service life.

Furthermore, in the present invention, as shown in FIGS. 1 to 3 , the fresh air housing structure further includes a box body 4, which has openings 41 on both sides in the front-rear direction, and two housing plates 1 are provided, and the two housing plates 1 are detachably connected to the box body 4 and cover the corresponding openings 41. This can make the structure of the fresh air blower 100 more compact and beautiful, and also facilitate the maintenance and cleaning of the interior thereof.

Preferably, the fresh air housing structure has a packaging state in which the two housing plates 1 are located in the air duct 11, and an assembly state in which the two housing plates 1 are respectively installed on both sides of the box body 4 in the front-rear direction. In this way, when installing the fresh air fan, the fresh air housing structure can be adjusted to the packaging state during transportation and storage to reduce its overall volume, facilitate transportation and storage, and avoid the fresh air fan 1 being damaged due to bumps caused by the protrusion of the wind tube during transportation or at the construction site. When installing the fresh air fan 100, it can be adjusted to the assembly state, and the assembly operation is simple and the installation efficiency is high.

The fresh air fan 100 provided by the utility model adopts a fresh air shell structure as its outer shell structure, so that the fresh air fan 100 has the advantages of smooth and beautiful appearance, high assembly efficiency, good sealing performance, and low working noise.

The utility model also provides a fresh air system, which includes the fresh air machine 100 as described above, and a ventilation duct connected to the fresh air machine 100, and the ventilation duct can be designed and arranged according to the actual space requirements to reasonably arrange the indoor air outlet and return air outlet of the ventilation duct.
