<p>The invention relates to a vacuum dust collector. The bottom of the vacuum dust collector is provided with an absorptive groove; an absorptive nozzle is disposed in the absorptive groove; and a guide influx channel is mounted on the front end of the bottom of the vacuum dust collector. The vacuum dust collector is characterized in that an upwardly-recessed intermediate influx channel is arranged between the absorptive groove and the guide influx channel; the lower part of the intermediate influx channel is equipped with a scrubbing brush component; a path is formed between the scrubbing brush component and the intermediate influx channel; the front end of the intermediate influx channel is communicated with the guide influx channel; the back of the intermediate influx channel is communicated with the absorptive groove; with the scrubbing brush component on the guide influx channel between the guide influx channel and the absorptive groove, efficiency of waste scrubbing can be improved; and with the path acting as a channel between the intermediate influx channel and the scrubbing brush component, absorption efficiency can be improved.</p> |
