Problems solved by technology

The air volume of the air inlet of the existing centrifugal fan cannot be adjusted, and the scope of application is small. At the same time, when not in use, dust is easy to enter from the air inlet, resulting in serious dust accumulation inside the fan, troublesome cleaning, and easy to shorten the service life of the fan.

Abstract

The invention discloses a centrifugal fan capable of adjusting the air volume of an air inlet. The centrifugal fan comprises a shell, the air inlet formed in the side face of the shell and an air outlet formed in the end surface of the shell; the side, close to the air inlet, of the shell is evenly provided with a plurality of fan-shaped baffles matched with the air inlet, the multiple fan-shapedbaffles form a circular structure, slide rails corresponding to the fan-shaped baffles in a one-to-one manner are arranged on the shell, the fan-shaped baffles are slidably arranged on the slide railsthrough sliders, toothed discs are rotationally arranged on the portions, on the outer sides of the sliding rails, of the shell through large bearing blocks, and a servo gear motor is arranged at theupper end of the shell, a first gear is arranged on a motor shaft of the servo gear motor, the first gear is engaged with first gear teeth on the outer sides of the toothed discs, and a swivel nut isrotationally arranged on the portion, on the outer sides of the sliding rails, of the shell through a small bearing block.

Description

technical field [0001] The invention relates to a fan, in particular to a centrifugal fan capable of adjusting the air volume of an air inlet. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. At present, the fan is widely used in various fields. The air volume of the air inlet of the existing centrifugal fan cannot be adjusted, and the scope of application is small. At the same time, when not in use, dust is easy to enter through the air inlet, resulting in serious dust accumulation inside the fan, troublesome cleaning, and easy to shorten the service life of the fan. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a centrifugal fan with good adjustment effect and adjustable air volume at the air inlet. [0004] In order to solve the above-mentioned technical problems, the technical solu...
