Description

The dirt cup bottom device of dust catcher

Technical field

The utility model relates to a kind of dirt cup bottom device 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.

But, along with improving constantly of environmental consciousness, the single-stage dust arrester can not satisfy user's requirement, the market demand efficiency of dust collection is higher, the discharge air is cleaner, can not produce the dust catcher of secondary pollution, therefore, manufacturer develops the dust catcher that contains firsts and seconds two-stage dust arrester again.

On concrete structure, the arrangement mode of two-stage dust arrester has varied, difference according to the two-stage dust arrester is arranged, and its mode of falling ash also has difference, for example, a kind of two-stage dust arrester structure arranged arranged side by side that is is arranged, the ash mouth that falls of the dust storage chamber of its primary dust removing device and two-stage dust removal device is in the bottom, therefore, only is provided with a shared bottom, when opening bottom, the dust storage chamber of two-stage dust arrester can fall grey simultaneously.But, when concrete the use,, can bring pollution to the user, even dust can be splashed on user's the body because ash is too fierce.

Summary of the invention
