Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a dust-proof blower. Background Art

[0002] A blower is a mechanical device used to increase the conveyance of gas. Its basic function is to convey gas from the suction side to the discharge side, and it is usually used for gas supply in industrial processes. The working principle of a blower depends on its type, but most blowers increase the kinetic energy of gas through a rotating impeller, which is then converted into pressure energy.

[0003] Common blowers generally use an electric motor as the power source of the blower to drive other components to rotate. The rotation of the impeller generates an air flow to drive the gas to flow, and a dust-proof net is installed at the air inlet to prevent dust from entering the blower.

[0004] In order to prevent the dust-proof net from being blocked by dust, a cleaning device is generally used to clean the dust adsorbed on the surface of the dust-proof net. However, when cleaning the dust-proof net, the cleaned dust easily passes through the holes of the dust-proof net, and the suction force generated by the blower sucks the passed dust into the interior, resulting in poor dust-proof effect for the blower. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a dust-proof blower to solve the problem that when cleaning the dust-proof net, the cleaned dust easily passes through the holes of the dust-proof net, and the suction force generated by the blower sucks the passed dust into the interior, resulting in poor dust-proof effect for the blower as mentioned in the above background art.

Through the suction port, the dust cleaned can be extracted from the surface of the first dust-proof net, making it difficult for the dust to enter the blower through the holes of the first dust-proof net. Moreover, the second dust-proof net can intercept the dust that has not been completely extracted, effectively preventing the dust from entering the blower and improving the dust-proof effect of the blower.
