Technical Field
The utility model relates to the field of mechanical equipment, concretely relates to low noise fan with shock-absorbing function.
Background
Fans are widely used in various fields such as production workshops as ventilation equipment. However, noise generated by interaction between an asymmetric structure around a fan blade and a circumferentially uneven flow field formed by design test rotation of a blade opening is a source of accidents affecting the health of workers and disturbing the quiet environment, and seriously interferes with normal work and rest of people, so that the noise becomes public nuisance. Thus, users are more focused on selecting devices that are equipped with high efficiency, low noise, and long lifetime. The fan of prior art has the noise big, the problem that the motor radiating efficiency is low.
SUMMERY OF THE UTILITY MODEL
Big to prior art fan noise, the problem that motor radiating efficiency is low, the utility model provides a low noise fan with shock-absorbing function.
The technical scheme of the utility model as follows:
a low-noise fan with a damping function comprises a supporting plate, wherein the supporting plate is fixedly connected with a shell of the fan; a buffer component is fixed between the bottom of the casing and the supporting plate; the bottom of the shell is provided with a vent, the outer surface of the vent is provided with a protective cover, and the center of the vent is provided with a heat dissipation impeller; the inner surface of the shell is bonded with a noise reduction material; a low-temperature air inlet is formed in the side surface of the shell; the top of casing is equipped with the bearing, the bearing bears the pivot, the motor is connected to the pivot.
Preferably, the noise reduction material is sound absorption cotton.
Inhale the sound cotton and acquire easily, and noise reduction effect is good.
Preferably, the low-temperature air inlets are uniformly distributed along the circumference of the shell.
The plurality of low-temperature air inlets can ensure that the surface of the motor is uniformly cooled.
Preferably, the buffer component is a high-activity soft adsorption material.
The buffering subassembly is stable high active soft adsorption material, when the fan vibration, can play the cushioning effect to the backup pad vibration that the fan effect arouses, and the soft adsorption material of preferred stable active can reach vibration/noise reduction's effect.
Preferably, the shield is a porous metal shield.
Inside the porous metal protection casing can avoid large granule magazine to get into the casing, effectively protected the normal operating of fan.
The utility model discloses compare and have following beneficial effect in prior art:
the utility model discloses a be fixed with the buffering subassembly between the bottom of casing and the backup pad, casing and backup pad production resonance in avoiding the tradition reduce the production of vibration. Meanwhile, the noise reduction material is bonded in the shell, so that the noise generated by the vibration of the shell is further reduced.
