Example 1

The embodiment provides a fan assembly 100, please refer to fig. 1 to 2, the fan assembly 100 includes a housing 1, a fan 2 and a mesh member 3, the fan 2 and the mesh member 3 are both disposed in the housing 1, an opening is disposed on the housing 1, the fan 2 has an air inlet end and an air outlet end, an air inlet channel is formed between the air inlet end of the fan 2 and the opening on the housing 1, and an external air flow flows from the opening on the housing 1 to the air inlet end of the fan 2 and then blows out from the air outlet end of the fan, wherein the mesh member 3 is disposed in the air inlet channel between the opening and the air inlet end of the fan 2 and is disposed opposite to the air inlet end of the fan 2, the mesh member 3 is a sheet member having a plurality of through holes, occupies a small space in the housing, and can guide the air flow entering the fan 2 through the mesh member 3, thereby reducing the aerodynamic noise of the air flow before entering the fan 2 and reducing the working noise of the fan assembly 100; and because the net shape part 3 can make the mesh that the aperture is little and the quantity is more, the mesh rate can be made higher, is difficult for blockking the air current, reduces flow field energy loss, makes the airflow that gets into fan 2 bigger to the air output that makes this fan subassembly 100 can be bigger, and the user experiences and feels better.

Specifically, the mesh rate of the mesh member 3 should be kept between 30% and 80%, so as to avoid the influence on the air output due to too small mesh rate and too large wind resistance, and avoid the problem that the strength of the mesh member 3 is not ensured due to too large mesh rate. The mesh opening rate of the net-shaped member 3 is controlled to be 30% -80%, such as 30%, 40%, 50%, 60%, 70% and 80%, etc., so that the strength of the net-shaped member 3 can be ensured, the net-shaped member is not easy to deform, the wind resistance is smaller, the energy loss of a flow field is reduced, the air flow entering the fan 2 is larger, and the air outlet amount is particularly good.

Preferably, the aperture of the through-hole of the net-shaped piece 3 is between 0.2mm ~ 1mm, the aperture undersize of the through-hole of the net-shaped piece 3, the windage of formation is too big, may lead to the air current to pass through completely, may lead to even that 2 air inlet end of fan department forms the negative pressure, influence the normal work of fan 2, and if the aperture of the through-hole of the net-shaped piece 3 is too big, then can't play the effect of leading to the air current, make the air current noise that gets into fan 2 too big, influence the user and use experience and feel. Therefore, the aperture of the through hole of the net-shaped member 3 is set to be 0.2 mm-1 mm, such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, 1mm, etc., so that the air flow can be guided, the pneumatic noise is small, and the sufficient air flow can be ensured to ensure the air output of the fan assembly 100.

Preferably, the net-shaped member 3 can be a metal net, so that the strength is better, and the metal material can be used for easily manufacturing meshes with small apertures and more quantity, so that the manufacturing is more convenient.

Furthermore, the mesh 3 is located in front of the air inlet end of the fan 2 to guide the airflow entering the fan 2, and it can be understood that the distance between the mesh 3 and the air inlet end of the fan 2 is not small enough, and the small distance makes the flow direction of the airflow not optimized, i.e. entering the fan 2, and therefore does not play a role in guiding, but if the distance is too large, the guiding also does not play a role, preferably, as shown in fig. 3 and 4, the distance d1 between the mesh 3 and the air inlet end of the fan 2 is generally 0.5cm to 3cm, so that after the airflow passes through the mesh 3, the airflow is guided through the through holes on the mesh 3, thereby reducing the aerodynamic noise of the airflow before entering the fan 2, and thereby reducing the working noise of the whole fan assembly 100.

Moreover, in order to make the airflow more stable after flowing through the fan 2, preferably, the fan 2 is set as an axial flow fan 2, an air inlet end and an air outlet end of the axial flow fan 2 are respectively located at two axial ends of the impeller, and the flow direction of the airflow from the air inlet end to the air outlet end is consistent, at this time, a plurality of net-shaped members 3 can be arranged, and the plurality of net-shaped members 3 are distributed in a stacked manner along the axial direction of the axial flow fan 2, so that the guidance for the airflow is better, and the aerodynamic noise is effectively reduced.

The shape of the mesh of the net 3 is not limited, and may be circular, triangular, or other polygonal shapes.

In this embodiment, the housing 1 is cylindrical, and the mesh 3 is a disc-shaped member matching with the inside of the housing 1, wherein the fan 2, the mesh 3 and the housing 1 are coaxial, so that the airflow flowing in the housing 1 is more stable.

Further, in order to facilitate installation of the mesh-shaped member 3, the housing 1 may be provided in a sectional manner, specifically, as shown in fig. 2, the housing 1 includes a first housing 11 and a second housing 12 connected to each other, the first housing 11 and the second housing 12 are oppositely disposed, a first clamping groove is formed on the first housing 11, a second clamping groove is formed on the second housing 12, and the first clamping groove and the second clamping groove clamp both sides of the mesh-shaped member 3 together to fix the mesh-shaped member 3 in the housing 1, so as to facilitate replacement and maintenance of the mesh-shaped member 3. The connection between the first housing 11 and the second housing 12 can be made by snap-fit structures and/or connectors (e.g., screws, bolts, etc.). The above-mentioned openings may be provided in plural, and the plural openings are uniformly arranged along the circumferential direction of the first housing 11 and the second housing 12.

Moreover, the outer shell 4 can be further arranged on the outer side of the shell 1, the outer shell 4 is wrapped on the outer sides of the first shell 11 and the second shell 12, the structure is more compact, the end portion of the outer shell 4 can be further provided with the end cover 5, the end cover 5 is provided with a plurality of air inlet holes communicated with the opening, the air inlet holes are arranged in a net shape, and external impurities can be prevented from entering the air portion of the fan assembly 100.
