In this embodiment, the connecting member 306 is a blade 361, the cross-section of which has two curves arranged in sequence along the direction of rotation 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 In this way, by increasing the length of the string 373, the air volume of the laminar flow fan 110 can be greatly increased, thereby promoting laminar air circulation. It should be noted that the two curves can be circular arcs, non-circular arcs, straight lines and other lines, and the straight line can be used as a special curve. When the distance between the two end points of the two curves is the same, the length of the chord line 373 may be the distance between the two end points of the two curves.

When the outer and inner diameters of the annular disc 301 are constant, although the longer the chord 373, the greater the air volume and pressure of the laminar flow fan 110, but the length of the chord 373 must be restricted to avoid the blade 361 Excessive penetration of the annular disk 301 causes the stability of the laminar flow fan 110 to decrease.

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 inside to the outside. Taking the laminar flow fan 300 arranged in the upper part of the casing 200 as an example, each annular disc 301 is arranged as an arc-shaped disc that gradually rises from the inside to the outside and protrudes upward, so that the outside air enters the laminar flow fan 300 The angle of φ is more in line with the fluid flow, so that it is more conducive for external air to enter the laminar flow fan 300, effectively reducing air volume loss, and ensuring that the air output of the laminar flow fan 110 meets the needs of users. FIG. 34 is a schematic diagram of the central angle θ of the connection between the inner and outer diameters of a plurality of annular disks 301 on the same longitudinal section passing through the central axis. 35 is a schematic diagram of the relationship between the central angle θ and the air volume and air pressure when the outer diameter, number of layers, spacing, thickness of the annular disc 301, and the rotation speed of the motor 400 remain unchanged. As shown in Figure 35, when the above-mentioned parameters remain unchanged, as the central angle θ gradually increases, the air volume first increases and then decreases, while the wind pressure increases slightly.
