The utility model has the advantages that: this resonance fan casing is prevented to low noise has following advantage:
1. the center of the shell can be changed continuously through the anti-resonance component, so that resonance cannot occur between the motor and the shell, and the fan and the shell are protected;
2. the cross section of the reinforcing strip is isosceles trapezoid, the short edge of the isosceles trapezoid is close to the fan blade, so that the area of the reinforcing strip contacted by wind at first is small, and meanwhile, the reinforcing strip is guided by the side edge of the reinforcing strip, thereby greatly reducing the wind resistance and reducing the wind noise.
Drawings
The invention will be described by way of example and with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of the present invention with the fan cover removed;
fig. 3 is a schematic structural view of the reinforcing strip of the present invention.
In the figure: 1. the fan comprises a shell, a frame 2, a base 3, a lantern ring 4, a magnet 5, a guide rod 6, a guide groove 7, a fan blade 8, a fixing rod 9, a motor 10 and a reinforcing strip 11.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, a low-noise anti-resonance fan casing includes a base 3, a casing 1 and a fan housing, the fan housing is connected to the casing 1, the casing 1 is disposed on the base 3, a motor 10 is disposed inside the casing 1, the motor 10 is in transmission connection with a plurality of fan blades 8, and the motor 10 is connected to the casing 1 through a fixing rod 9;
an anti-resonance assembly is arranged inside the base 3 and comprises a lantern ring 4, a guide rod 6 and two magnets 5, the lantern ring 4 is sleeved on the periphery of the guide rod 6, the two magnets 5 are positioned at the upper end and the lower end inside the base 3, the guide rod 6 is vertically arranged between the two magnets 5, the lantern ring 4 is made of magnets, the polarity of the upper end of the lantern ring 4 is opposite to that of the lower end of the magnet 5 positioned above, and the polarity of the lower end of the lantern ring 4 is opposite to that of the upper end of the magnet 5 positioned below;
the fan housing includes frame 2 and a plurality of reinforcement strip 11, and each reinforcement strip 11 evenly sets up at the preceding terminal surface of frame 2, and frame 2 is connected with casing 1, and reinforcement strip 11's cross-section is isosceles trapezoid, and isosceles trapezoid's minor face is close to flabellum 8.
In the low-noise anti-resonance fan shell, when the fan works, the lantern ring 4 moves up and down on the guide rod 6 due to vibration, and the lantern ring 4 and the upper and lower magnets 5 repel each other, so that the gravity center of the base 3 continuously changes due to up-down movement, so that when the fan works, the vibration frequency of the motor 10 is unchanged, the base 3 and the shell 1 are integrated, and the vibration frequency continuously changes due to the change of the gravity center, so that the motor 10 and the shell 1 cannot resonate, and the fan and the shell 1 are protected; and when the wind that flabellum 8 blown passes through reinforcing strip 11, because the cross-section of reinforcing strip 11 is isosceles trapezoid, isosceles trapezoid's minor face is close to flabellum 8 for wind contacts the area of reinforcing strip 11 less at first, leads by reinforcing strip 11 side simultaneously, greatly reduced the windage, reduced wind and made an uproar.
