technical field

FIG. 22 is a schematic diagram of the air circulation of the laminar flow fan 110 shown in FIG. 20 . The center of the plurality of annular discs 301 is jointly formed with an air inlet channel 302 to allow the air outside the laminar flow fan 300 to enter; the plurality of annular discs 301 A plurality of discharge ports 303 are formed in the gaps between them, so that the laminar flow can be blown out.

The connecting members 306 of the laminar flow fan 300 may be blades 361, connecting rods 362, and the like.

FIG. 23 is a schematic cross-sectional view of the laminar flow fan 110 shown in FIG. 20 . In this embodiment, the connecting member 306 is a blade 361, and its cross section has two curves arranged in sequence along the rotation direction of the annular disc 301. The length of the chord line 373 of the two curves is linear with the air volume of the laminar flow fan 110. Therefore, by increasing the length of the string 373, the air volume of the laminar flow fan 110 can be greatly improved, thereby promoting the laminar flow air circulation. It should be noted that the two curves can be arcs, non-circular arcs, straight lines, etc. The straight line can be used as a special curve. When the distances between the two end points of the two curves are the same, the length of the chord line 373 may be the distance between the two ends of the two curves. When the distances between the two end points of the two curves are different, if both ends of the two curves do not intersect, the length of the chord line 373 may be the length of the midpoint of the cross section of the blade 361 except for the two curves.

The annular discs 301 of the laminar flow fan 300 can also be arranged in one or more of the following structures: the distance between two adjacent annular discs 301 gradually increases along the direction of air flow in the air inlet channel 302 The inner diameters of the plurality of annular discs 301 gradually decrease along the direction of the airflow in the air inlet channel 302;

In some embodiments, the plurality of annular disks 301 of the laminar flow fan 300 are arranged in parallel and spaced apart from each other, have the same central axis, and the distance between two adjacent annular disks 301 is along the air in the air inlet channel 302 The direction of flow gradually increases.

When the variation between the inner diameter of each annular disc 301 and the inner diameter of the adjacent annular disc 301 shown by the abscissa axis is a positive number, it means that the inner diameters of the plurality of annular discs 301 gradually increase from bottom to top; When the variation between the inner diameter of each annular disk 301 indicated by the coordinate axis and the inner diameter of the adjacent annular disk 301 below is a negative number, it means that the inner diameters of the plurality of annular disks 301 gradually decrease from bottom to top.

Considering the overall air volume and wind pressure, the variation between the inner diameter of each annular disc 301 and the inner diameter of the adjacent annular disc 301 below can be set to -5mm, that is to say, the inner diameters of the eight annular discs 301 are respectively For: 115mm, 110mm, 105mm, 100mm, 95mm, 90mm, 85mm, 80mm.

In some embodiments, the annular disk 301 of the laminar flow fan 300 is an arc-shaped disk gradually approaching the driving disk 305 from the inner side to the outer side. Taking the laminar flow fan 300 disposed in the upper part of the housing 200 as an example, each annular disc 301 is set as an arc-shaped disc that gradually rises from the inside to the outside and protrudes upwards, so that the outside air enters the laminar flow fan 300 The angle is more in line with the fluid flow, which is more conducive to the entry of external air into the laminar flow fan 300, effectively reducing the loss of air volume, and ensuring that the air outlet of the laminar flow fan 110 meets the user's use requirements.
