Description
Technical field
The utility model relates to a kind of dust catcher.
Background technology
Filter mantle or dust bag all are housed in the existing dust catcher, purpose is with filter mantle or dust bag the dirty air that vacuum motor sucks to be filtered, and dust granule stayed in control of dust tube or the dust bag, therefore, above-mentioned dust catcher is after using a period of time, the user should clear up filter mantle or dust bag or change, otherwise, after the filtering holes of filter mantle or dust bag is stopped up by thin dust, can increase the dust suction resistance of vacuum motor, severe patient even can burn out motor, so, traditional dust catcher also exists many weak points on its structure, it has not only brought trouble to the user, has also influenced the serviceability of dust catcher.
In order to overcome above-mentioned shortcoming, production firm is applied in the dust arrester of dust catcher with the cyclonic separation principle, and obtains result of use preferably.This cyclonic separation dust arrester is provided with the back taper cylindrical shell that a upper end is big, the lower end is little in dust-collecting box, the upper end closed of back taper cylindrical shell also vertically is provided with a discharge pipe, the lower ending opening of back taper cylindrical shell is so that dust falls into the dust-collecting box bottom, blast pipe also tangentially enters in back taper cylindrical shell upper portion side wall, make the air-flow that has dust in the back taper cylindrical shell, produce rotation, dust granule drops to the dust-collecting box bottom at action of centrifugal force lower edge back taper cylinder lateral wall, and the air-flow after the dedusting is upwards discharged through discharge pipe.
Patent Office of the People's Republic of China in October 17 calendar year 2001 Granted publication by the applicant application, the patent No. is that ZL00266255.8, notification number are the utility model patent " the split-type cyclone dust filter device of dust catcher " of CN2453827.This patent " discloses a kind of split-type cyclone dust filter device of dust catcher; comprise a container; container is provided with dirty air intlet and cleaned air outlet; described container is separated into thick dirt chamber and thin dirt chamber, and thick dirt chamber is provided with rotary barrel, is provided with the filtration webmaster in the rotary barrel; dirty air intlet is positioned at the last side of thick dirt chamber; the thin indoor rotating cone that is provided with of dirt, the top of rotating cone are the cleaned air outlet, and described filtration webmaster is provided with a guiding air channel that is communicated with rotating cone; This device has changed the filter type of traditional dust catcher, adopts the structure of cyclonic separation, and it is cleaner that dirty air filtration is got, nor can increase the dust suction resistance of motor, and the use of returning the user has simultaneously brought convenience.”
Because the rotary barrel of above-mentioned patented product is the back taper shape, quicken rotation by air-flow and come dust-separating, so the pressure loss of air-flow is bigger, thereby influenced the pick-up performance of dust catcher.In addition, the air-flow of acceleration will sink to the fine dust of bottom easily and kick up once more, and discharge from discharge pipe with air-flow, thereby make air produce secondary pollution.In addition, this product is suitable for the separate coarse particulate dust, and is then relatively poor relatively to the separating effect of fine particle dust.
