Problems solved by technology

This kind of fan keeps running in one direction for a long time, which is easy to cause dust accumulation. The accumulated dust will increase the weight of the fan blades, increase power consumption, and reduce air volume, which will affect the life of the fan and the heat dissipation of the system.

Embodiment

[0022] Embodiment: a dust removal fan, including a casing 1 and a fan blade 2, the fan blade 2 is rotatably installed in the casing 1, a number of blades 3 inclined in the same direction are formed on the outer wall of the fan blade 2, and the A dust removal hole 4 is formed on the side wall of the housing 1 , and the dust removal hole 4 can connect the inside and outside of the housing 1 .

[0023] When the fan is running normally, the windshield 5 will close the dust removal hole 4, so that the air volume of the fan under normal working conditions will not be reduced due to the increase of the dust removal function; The dust stirred by the reverse rotation of the fan is discharged from the fan through the dust removal hole 4 under the blowing of the reverse rotation compressed air, so as to realize the automatic cleaning of the fan and avoid the accumulation of dust in the fan, which is conducive to maintaining a stable air output of the fan and improving its heat dissipation...

Abstract

The invention discloses a dust removing fan. The dust removing fan comprises a shell and a fan blade; the fan blade is rotatably installed in the shell, and a plurality of blade bodies which incline in the same direction are arranged on the outer side wall of the circumference of the fan blade; the side wall of the shell is provided with a dust removing hole, and the interior and the exterior of the shell can communicate with each other through the dust removing hole; and the side wall of the shell is provided with an air baffle, and the dust removing hole can be opened or closed through the air baffle. According to the dust removing fan, the structure is simple, when the dust removing fan normally runs, the dust removing hole is closed through the air baffle, air can not flow out from thedust removing hole, therefore, the effective air volume of the fan is guaranteed, and the air volume of the fan under the normal working condition can not be decreased due to additional achievement of a dust removing function; and when dust removing is conducted, the air baffle is automatically opened, automatic dust removing is achieved, the condition that the weight is increased due to the factthat dust is accumulated on the fan blade is avoided, power dissipation can be reduced, the air volume is guaranteed, the heat dissipation effect of the system is improved, and the service life of the fan is prolonged.

Description

technical field [0001] The invention relates to a fan, in particular to a dust removal fan. Background technique [0002] Generally, the direction of the blower fan is fixed, such as figure 1 For a fan that runs counterclockwise. This kind of fan keeps running in one direction for a long time, which is easy to cause dust accumulation. The accumulated dust will increase the weight of the fan blades, increase the power consumption, and reduce the air volume, which will affect the life of the fan and the heat dissipation of the system. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a dust removal fan. When the dust removal fan operates in the opposite direction, the dust will be stirred and discharged from the dust removal hole, so as to realize the effect of automatic dust removal by the fan. [0004] The technical solution adopted by the present invention to solve the technical problem is: a dust removal...
