Abstract

The invention discloses a fan with a noise reduction structure. The fan comprises a volute, an air inlet, an impeller, an air outlet, a rotating shaft and a motor, a partition plate is fixedly installed on the inner wall of the volute, a spiral groove is fixedly installed between the partition plate and the volute, the two ends of the spiral groove are connected with the volute and the partition plate respectively, the air inlet is formed in the center of the volute, the impeller is arranged in the air inlet, an inclined groove is formed in the outer wall of the impeller, a dust collecting plate is fixedly installed in the inclined groove, a through hole is formed in the side face of the dust collecting plate, the air outlet is fixedly formed in the top of the volute, and a water injection opening is formed in the top end of the air outlet. The dust collecting plate is arranged, dust contained in outside air can be filtered, noise generated by the impeller can be absorbed through the partition plate and the spiral groove, the dust in the outside air can fall through a water outlet pipe, and the situation that the dust in the outside air flies around, and a human body absorbs a large amount of dust is avoided.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan with a noise reduction structure. Background technique [0002] With the continuous development of society and the continuous progress of industry, the fan is composed of air inlet, impeller, motor and air outlet, etc. It mainly blows the wind in the air through the fan to form an airflow outside. When the fan is working, the noise is relatively loud, and the dust contained in the air is easy to move with the wind, so that the dust flies in the air, causing the human body to absorb a large amount of dust, which is not conducive to health. When the fan is in motion, it is easy to blow the outside air The dust in the fan is sucked into the inside of the fan, and then it is blown to the outside together by the wind. When it is blown on the human body, it is easy to make the human body absorb a large amount of dust. Therefore, a fan with a noise reduction structure is urgently nee...
