Description

Technical Field

[0001] The present invention relates to the technical field of axial flow fans, in particular to a vibration-reducing axial flow fan with high aerodynamic performance. Background Art

[0002] High-performance axial fans are those optimized in design and manufacturing to provide high air flow while maintaining high efficiency and low energy consumption. These fans are commonly used in industrial, commercial, and architectural applications such as ventilation, air conditioning, smoke exhaust, and air purification systems.

[0003] In the prior art, axial flow fans are mainly composed of a motor, fan blades and a casing. However, since the wind force of the axial flow fan is relatively large when in use, the power of the motor is relatively large, and the larger the power of the motor, the greater the vibration generated when in use. The vibration reduction measures for axial flow fans in the prior art are basically to install soft blocks for vibration reduction at the bottom of the fan, such as rubber blocks. However, these vibration reduction blocks that play a buffering role are still relatively hard, resulting in limited vibration reduction effect. Poor vibration reduction effect will cause the vibration to be transmitted to the fan, causing internal components to be damaged due to vibration, thereby reducing the service life of the axial flow fan. Summary of the Invention

[0022] Working principle: When in use, first start the motor, and the output end of the motor rotates to drive the fan to rotate, thereby generating wind force. When the fan rotates to generate wind force, it also generates vibration, and the vibration is transmitted to the fan frame through the mounting frame and the mounting base. At this time, the vibration force is transmitted to the connecting block through the fan frame. After the connecting block moves downward, it can drive the limit plate to move downward. The downward movement of the limit plate can compress the buffer spring. At the same time, the liquid inside the internal sliding groove is squeezed by the limit plate and enters the interior of the liquid storage tank through the through hole. Under the action of the buffer spring, the limit plate can be pushed upward, thereby sucking the liquid inside the liquid storage tank into the interior of the internal sliding groove through the through hole, thereby reducing the vibration of the buffer spring, and then playing a buffering role, which can effectively slow down the vibration.

[0024] As the fan rotates, the fixed rod can be driven to rotate, and when the fixed rod rotates, the limiting square plate can be driven to rotate, and when the limiting square plate rotates, the connecting square rod can be driven to rotate, thereby driving the cleaning plate to rotate, and then the protective mesh cover can be cleaned, thereby preventing dust from adhering to the protective mesh cover or the fan frame near the inner wall of the fan, thereby increasing the wind force.

[0025] The present invention provides a vibration-reducing axial flow fan with high aerodynamic performance. It has the following beneficial effects:

[0026] 1. The present invention can utilize the cooperation of the buffer spring and the internal sliding groove liquid through the buffer mechanism when the fan vibrates, which can overcome the continuous vibration of the spring and effectively buffer the vibration, thereby reducing the vibration generated when the axial flow fan is in use, and then protecting the internal components of the fan, thereby increasing the service life of the axial flow fan.

[0027] 2. The present invention drives the cleaning mechanism to rotate by rotating the fan, and at the same time drives the wind force lifting mechanism to rotate, so that the interior of the fan frame close to the fan side and the protective mesh cover can be cleaned, thereby preventing the air outlet from being blocked and then increasing the wind force.
