Pulse dust collector with pre-dedusting function

The utility model discloses a pulse dust collector with a pre-dedusting function, which comprises a pulse dust collector, the left side of the pulse dust collector is communicated with a first transverse pipe, the left end of the first transverse pipe is fixedly connected with a first rubber ring, and the first transverse pipe and a second transverse pipe are fixed together through a fixing device. According to the pulse dust collector with the pre-dedusting function, through cooperation of an annular filter screen, a spring, a short pipe, a first rubber ring, a second rubber ring, a hairbrushand a box body, pre-adsorption of dust is achieved, and the adsorption effect of the dust is greatly improved due to the fact that water is attached to the outer wall of the annular filter screen, sothat little dust enters the pulse dust collector; compared with the prior art, the pulse dust collector with the pre-dedusting function has the advantages that the operation effect is better, and thepulse dust collector with
