The dust arrester of dust catcher
Technical field
The utility model relates to a kind of dust arrester of dust catcher.
Background technology
Dust arrester is installed in the dust catcher, discharges body after the dirty air filtration that dust arrester will suck, and dust granule is collected in the dirt cup.The dust arrester of conventional cleaners is exactly in fact a filter, therefore, dust catcher is after using a period of time, the user should clear up filter or change, otherwise, after the filter opening of filter is stopped up by thin dust, can increase the resistance of vacuum motor, severe patient even can burn out motor has not only brought trouble to the user, and can influence the performance and the life-span of dust catcher.
In recent years, manufacturer substitutes filter according to the principle of cyclonic separation with cyclone dust collector, has obtained dust removing effects preferably, thereby has been widely applied on the dust catcher.This cyclone dust collector is provided with a conical cyclone tube in the dirt cup, the upper end of whirlwind tube vertically is provided with a discharge pipe, and be communicated with the air outlet of dirt cup, the lower end of whirlwind tube is provided with opening, so that dust falls into the disposal box of dirt cup bottom, blast pipe also tangentially enters in whirlwind tube upper portion side wall, make the air-flow that has dust in the whirlwind tube, produce whirlwind, dust granule drops to the dust-collecting box bottom at action of centrifugal force lower edge whirlwind tube sidewall, and the air-flow after the dedusting is upwards discharged the dirt cup through discharge pipe.
